DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
[0027] Although the invention is illustrated and described herein
with reference to specific embodiments, the invention is not
intended to be limited to the details shown. Rather, various
modifications may be made in the details within the scope and range
of equivalents of the claims and without departing from the
invention.
[0028] The present invention relates to a cleaning apparatus
comprising at least one cleaning tool for cleaning an object to be
cleaned, an operating unit for a user, which comprises at least one
operating element for operating the cleaning apparatus, a control
unit for processing operating instructions, a receptacle, arranged
on the operating unit, for an external accessory that can be
associated with the cleaning apparatus and that has a display
device with an image display, wherein the accessory is removably
positionable in the receptacle in a defined position, as well as a
communication unit by way of which display information for being
displayed on the image display are transmittable from the cleaning
apparatus to the accessory positioned in the receptacle.
[0029] In the cleaning apparatus in accordance with the invention,
it is possible to display information about the state and/or the
operation in the image display of the external accessory. For this
purpose, display information defining the image content can be
transmitted from the communication unit to the accessory. The
communication unit may be in operative connection with the control
unit, be formed thereby, or be integrated therein. So that the
image display can be easily seen by the user, the cleaning
apparatus comprises a receptacle for the accessory, arranged on the
operating unit, in which the accessory can be removably arranged.
It is thereby possible, in particular, to position the accessory in
a defined manner, in particular in the viewing direction of the
user during the intended use of the cleaning apparatus, in which
said user, for example, interacts with operating elements of the
operating unit. By way of the defined position of the accessory in
the receptacle, it is preferably simultaneously ensured that a
reliable transmission of display information from the communication
unit to the accessory is securely provided.
[0030] By means of the present invention, it is possible, for
example, for display devices of accessories in the possession of
the users to be able to be used, for example smartphones and/or
tablet computers, which the users would carry with them anyway when
working with the cleaning apparatus. If necessary, communicative
connections establishable with the accessory can preferably be used
by way of a communication network. A portion of the operating unit
of the cleaning apparatus can be exported, so to speak, and is
carried by the users. This is advantageous, for example, if
information regarding or about the operation of the cleaning
apparatus is saved on the accessory or is provided thereby. As a
result, for example, the work of the user with different cleaning
apparatuses, even of the identical kind, is made easier. Moreover,
it is possible to, at least partially, save a display device in the
cleaning apparatus or to configure said display device in a
relatively inexpensive manner. This prevents, for example,
cost-intensive maintenance and reconstruction in order to keep the
presentation of information up to date or to update it.
[0031] Unless anything to the contrary is stated in the following,
it is to be assumed that the accessory is positioned in the
receptacle.
[0032] The accessory is preferably an accessory in flat design, the
extent of which in one spatial direction is significantly smaller
than the respective extent in the two other spatial directions. An
image plane defined by the display device is preferably parallel to
a plane defined by the receptacle, for example the abutment plane
mentioned below.
[0033] Provision may be made for the accessory to be positionable
with the image display in landscape format and/or in portrait
format.
[0034] In the cleaning apparatus in accordance with the invention,
an electronic interface via the communication unit to the accessory
is present. Additionally, by way of the receptacle, a mechanical
interface to the accessory is present.
[0035] It is favorable if the receptacle comprises or forms at
least one abutment element against which the accessory abuts. A
defined position of the accessory in relation to the cleaning
apparatus in at least one spatial direction can thereby be ensured.
Favorably, at least one bearing element is present, on which the
accessory bears.
[0036] The abutment element or bearing element is, in particular,
of flat and/or planar configuration. As a result, a largest
possible contact surface with the accessory can be provided.
[0037] It is favorable if the receptacle comprises or forms a
shoulder for abutting against and, in particular, bearing the
accessory. The shoulder may be formed, for example, by a projecting
bar, rib, or edge of the receptacle. By way of the shoulder, it is
possible for the accessory to be oriented relative to the operating
unit in two spatial directions, whereby the accessory can adopt a
particularly well defined position.
[0038] The receptacle, in particular the abutment element or
bearing element for the accessory, preferably defines an abutment
plane. The abutment plane preferably encloses an angle with the
horizontal of about 0.degree. to 90.degree., preferably about
30.degree. to 60.degree., and further preferably about 45.degree..
In this way, for example, in the case of an accessory in flat
design, a surface normal of the image display can be oriented
approximately vertically to approximately horizontally, preferably
about at an angle of 45.degree. to the horizontal. In advantageous
implementations of the cleaning apparatus, it has been shown that
the content of the image display can thereby be seen and read
particularly well by the user.
[0039] Indications of position, orientation and alignment like e.g.
"horizontal", "vertical", "at the top", "at the bottom" or the like
are presently to be interpreted in relation to an intended use of
the cleaning apparatus. The cleaning apparatus can thereby be
positioned, in particular, on a placement surface presently taken
to be oriented horizontally. The "horizontal" of the last mentioned
advantageous embodiment may thus be a reference plane in parallel
to a contact plane of the cleaning apparatus with the placement
surface.
[0040] The receptacle is preferably arranged or arrangable on the
operating unit in such a way that the image display of the
accessory positioned in the receptacle defines an image plane
substantially perpendicular to the viewing direction of the
user.
[0041] A surface normal of an abutment plane defined by the
receptacle, in particular of the abutment element for the
accessory, is favorably oriented in a vertical plane.
[0042] The receptacle preferably comprises at least one frictional
coefficient-increasing element against which the accessory is able
to abut, or such a frictional coefficient-increasing element is
arranged an the receptacle. As a result, an increased frictional
force of the accessory on the receptacle can be increased. This
secures the position of the accessory in the receptacle even during
the operation of the cleaning apparatus, which is associated with
vibrations, for example. The frictional coefficient-increasing
element is configured, for example, to be flat, e.g. as a mat or
the like. Alternatively, it is conceivable for a plurality of
discrete frictional coefficient-increasing elements to be provided,
for example nubs. The frictional coefficient-increasing element is
preferably made of an elastically deformable material.
[0043] It is advantageous if the receptacle is movable relative to
the operating unit for changing a viewing angle of the user on the
image display. This enables a user-friendly and versatile
configuration of the cleaning apparatus. For adapting to the height
of the user, his/her location relative to the cleaning apparatus,
and/or his/her viewing direction, the position of the receptacle on
the operating unit can advantageously be varied. The receptacle is
favorably pivotable relative to the operating unit, in particular
about a horizontal axis. The horizontal axis extends e.g. in a
transverse direction of the cleaning apparatus. The adjustment of
the receptacle relative to the operating unit may be of continuous
or discrete configuration. The receptacle may favorably be set such
that the user can look substantially perpendicularly at the image
plane of the image display.
[0044] It is favorable if the receptacle is adjustable over an
angular range of at least about 45.degree., preferably of about
90.degree.. For example, the abutment plane of the receptacle can
be changed from an approximately horizontal to an approximately
vertical orientation.
[0045] Provision may be made for the cleaning apparatus to comprise
a housing that, in relation to a longitudinal direction of the
cleaning apparatus, is arranged in front of the operating unit. A
housing of that kind may be used e.g. in a cleaning apparatus
configured as a scrubber-dryer machine, sweeping machine, or
suction sweeping machine.
[0046] The housing may have a movable housing part arranged in
front of the operating unit, which housing part is pivotable from a
closed position in the direction of the operating unit into an open
position and vice versa. The housing part is e.g. a lid of a tank
of the cleaning apparatus for cleaning liquid.
[0047] It is favorable if the housing part in the open position is
free of contact with the receptacle and/or free of contact with the
accessory positioned in the receptacle. This ensures that the
position of the accessory in the receptacle is not negatively
affected when opening the housing part. An abutment element for the
housing part may preferably be provided on the cleaning apparatus,
for example on the operating unit, against which abutment element
the housing part strikes in the open position.
[0048] The operating unit preferably comprises a gripping device
for the user with two gripping elements arranged at a distance from
one another. In this way, the user can reliably guide the cleaning
apparatus, for example when configured as a walk-behind apparatus
or as a ride-on apparatus.
[0049] It proves to be advantageous if the gripping elements define
a gripping plane and if an abutment plane defined by the receptacle
defines an angle of less than about 20.degree. with the gripping
plane, preferably if the abutment plane extends in parallel or
substantially parallel to the gripping plane. It has been shown
that a user-friendly operation is possible in this way. For
example, the accessory may be positioned such that the image plane
of the image display is in parallel or substantially parallel to
the abutment plane. The angle between the image plane and the
gripping plane is preferably less than 20.degree. and more
preferably parallel or substantially parallel to the gripping
plane. Is has been shown that the image content can be reliably
seen by the user in this way.
[0050] In a preferred embodiment, the receptacle is arranged on the
operating unit offset in a direction away from the user relative to
the gripping elements. In the intended operation of the cleaning
apparatus, the accessory can in this way be further away from the
user than the gripping elements. The accessory is, in a way,
arranged lower, offset relative to the gripping elements.
[0051] When interacting with the operating unit, the likelihood is
thereby reduced that the user accidentally comes into contact with
the accessory, the positioning thereof in the receptacle thereby
being ensured. The gripping elements are, conversely, preferably
offset in the direction of the user in relation to the receptacle
and preferably the accessory.
[0052] The offset of the receptacle may be e.g. about 5 cm to 20
cm, preferably about 10 cm to 15 cm.
[0053] It proves to be advantageous if the receptacle, in relation
to a transverse direction of the cleaning apparatus, is arranged
between the gripping elements, in a viewing direction of the user
toward the image display of the accessory arranged in the
receptacle. In the transverse direction, the image display is
thereby positioned between the gripping elements, such that the
image display and the hands can be within the field of view of the
user and can be seen by the user together and in a simple manner.
This makes it possible for the user to operate the cleaning
apparatus in a handling-friendly, intuitive manner with a natural,
upright posture and head position. As explained above, provision
may be made for the accessory to be arranged offset relative to the
gripping elements, in particular with an offset away from the
user.
[0054] An operating element for acting on a chassis of the cleaning
apparatus is favorably arranged laterally next to a respective
gripping element, and the receptacle, in relation to the transverse
direction, is advantageously arranged between the operating
elements. In this way, the user can easily see the operating
elements for actuating the same and the image display for accepting
information displayed thereon, located within the field of view of
said user. This makes it easier for the user to operate the
cleaning apparatus.
[0055] In an advantageous implementation of the cleaning apparatus,
it is favorable if the gripping elements are configured as
longitudinal gripping elements and the receptacle, when the hands
of the user are placed with the thenar eminence against the
gripping elements, is arranged substantially in a region between
the bases of thumbs and the distal ends of the thumbs. The image
display and the hands, preferably together with the aforementioned
operating elements, are thereby located within a strip-shaped
visible region extending in the transverse direction, thus
facilitating the operation of the cleaning apparatus.
[0056] It is advantageous if the operating unit comprises at least
one operating element that is arranged in front of the user in
relation to the receptacle and preferably is arranged on the
operating unit below said receptacle. The operating element, in
particular a main operating element of the cleaning apparatus, can
thereby be easily reached and actuated by the user without having
to reach over or past the accessory arranged in the receptacle.
[0057] The operating element is e.g. a program selector switch for
setting a cleaning program of the cleaning apparatus and preferably
comprises a rotary grip or is configured as such. The positioning
in front of a preferably below the receptacle enables a
user-friendly actuation of the rotary grip.
[0058] In an advantageous implementation of the cleaning apparatus,
provision may be made for the operating unit to comprise an
operating field defining an operating plane, on which operating
field at least one operating element is arranged, for example the
aforementioned program selector switch. The operating plane is
advantageously arranged in front of the receptacle in relation to
the user. It proves to be advantageous if the operating plane is
oriented at an angle to an abutment plane defined by the
receptacle, wherein the angle may be e.g. about 10.degree. to
30.degree.. That angle is presently understood to be the smaller of
the two angles between the operating plane and the abutment
plane.
[0059] It is favorable if the receptacle for the arrangement of
accessories is configured having at least one of the following in
order to place a multitude of different accessories in the
receptacle where possible: [0060] accessories having a width of at
least about 15 cm, preferably up to about 25 cm; [0061] accessories
having a diagonal of the image display up to at least about 10
inches.
[0062] The operating unit is preferably arranged, in relation to a
longitudinal direction of the cleaning apparatus, on the rear side
thereof, for example in the case of a walk-behind apparatus like a
scrubber vacuum.
[0063] The cleaning apparatus preferably comprises a charging
device for providing electrical energy for the accessory, wherein
the accessory is able to be applied with electrical energy when
arranged in the receptacle. This makes it possible to increase
operating time of the accessory, preferably independently of the
use with the cleaning apparatus, in which display information are
transmitted to the accessory by way of the communication unit to
the accessory.
[0064] In a preferred embodiment, the charging device is an
inductive charging device for contactlessly acting upon the
accessory. For example, the charging device is arranged on the side
of the receptacle facing away from the accessory. The accessory can
be charged through the abutment element of the receptacle.
[0065] Provision may be made for the charging device to comprise at
least one electrical connecting element fixedly arranged on the
receptacle, which connecting element couples to a corresponding
electrical connecting element of the accessory. For example, the
connecting element is configured in the form of a docking
connector.
[0066] Provision may advantageously be made for the charging device
to comprise a connector socket (for example a USB socket) for
connecting a charging cable for the accessory.
[0067] In a similar manner, provision may preferably be made for
the charging device to comprise a charging cable with a connecting
element for connecting to an electrical connecting element of the
accessory.
[0068] In a preferred embodiment of the cleaning apparatus, it is
favorable if the cleaning apparatus comprises an integrated display
device, arranged on the operating unit, for displaying status
information, wherein the display device preferably comprises an
image display. For example, the display device is used when no
accessory is arranged on the receptacle. It can thereby be ensured
that information is provided visually to the user in order to make
the operation of the cleaning apparatus easier, even without an
accessory. Alternatively, provision may be made for the integrated
display device to be able to be used in combination with the image
display of the accessory.
[0069] Provision may be made for the display device to be at least
partially and in particular completely covered by the accessory
when the same is arranged in the receptacle. For example, a display
device of that kind is only used when no accessory is positioned in
the receptacle.
[0070] Provision may be made for the display device to be switched
off when the accessory is arranged in the receptacle and to be
activatable or activated when the accessory is removed from the
receptacle. This can preferably take place without intervention by
the user.
[0071] Provision may be made for no (further) display device to be
arranged on the operating unit, aside from that of the
accessory.
[0072] In a preferred embodiment of the cleaning apparatus, the
communication unit is configured to contactlessly transmit display
information to the accessory. For example, the display information
is transmitted by way of a radio connection, in particular a
Bluetooth connection. "Contactless" presently includes the
possibility that the accessory is physically in contact with the
receptacle. Merely the display information, the data for
controlling the image display, are transmitted without contact.
[0073] Alternatively or in addition, provision may be made for the
communication unit to be configured to transmit display information
in a contact-based manner, for example by way of a wired
connection.
[0074] Provision is favorably made for the communication unit to be
automatically activated to transmit the display information when
the accessory is positioned in the receptacle. This makes it easier
for the user to handle the cleaning apparatus. The presence of the
accessory may be mechanically and/or electrically detectable. For
example, a microswitch or a sensor element is provided, which is
actuated when the accessory is positioned in the receptacle.
Alternatively or in addition, a wireless coupling of the accessory,
in particular to the communication unit can be detected and the
image display thereby activated.
[0075] In a corresponding manner, provision may be made for the
communication unit to be automatically deactivated upon removal of
the accessory from the receptacle.
[0076] Provision may be made for display information relating to at
least one of the following to be transmittable to the
accessory:
[0077] information relating to the use of at least one cleaning
tool, for example the usage time, usage type, and/or wear thereto;
[0078] information relating to the consumption, the supply, or the
state of at least one consumable component used for the operation,
for example electrical energy, a cleaning liquid, and/or a cleaning
chemical. In particular, the information may relate to the state of
at least one battery, the amount/remaining amount of cleaning
liquid, the amount/remaining amount of a cleaning chemical, the
fill level of at least one container for cleaning liquid or dirty
liquid, and/or the state of at least one cleaning tool; [0079]
information relating to the elapsed usage time and/or the remaining
usage time of the cleaning apparatus; [0080] information relating
to the preceding usage type, for example the usage location, the
completed or foregone execution of a cleaning task and/or the
remaining usage type of the cleaning apparatus; [0081] instructions
for the user for assisting in cleaning, in particular for cleaning
tasks and/or for the optimization of the remaining usage. For
example, the user can be informed of remaining cleaning tasks and
preferably be assisted in the completion thereof.
[0082] It is favorable if status and/or operational information
relating to the operation of the cleaning apparatus is
transmittable by the communication unit to the accessory for
storage and/or forwarding to an external data processing device.
Display information for creating the image contents in the image
display may differ from the status and/or operational information
or coincide entirely or partially therewith. In the present
embodiment, the operation of the cleaning apparatus can be
monitored, wherein a report on the usage thereof can be created.
For example, the report may be evaluated with a view to an
improvement of the use of the cleaning apparatus and/or of the
coordination of users and/or a plurality of cleaning apparatus of a
cleaning fleet. The report can be saved in the accessory.
Alternatively or in addition, provision may be made for the report
to be transmitted for evaluation and/or archiving via a
communicative connection to a spatially remotely arranged data
processing device. The data processing device is, for example, in
the possession of or under management of a manufacturer or a user
of the cleaning apparatus.
[0083] For example, it can be tracked which user or which group of
users is using a particular cleaning apparatus. For this purpose,
it has proven to be advantageous if the cleaning apparatus is used
in conjunction with an access authorization, still to be described
in the following, and/or a user profile or an authorization
profile.
[0084] With the use of an external data processing device, it is
conceivable, in particular, for cleaning tasks to be created and
assigned to a plurality of users and/or cleaning apparatuses by way
of said data processing device. Corresponding cleaning tasks may,
for example, be transmitted to the accessory or, alternatively or
in addition, to the cleaning apparatus. The cleaning tasks can be
constituted differently in dependence on with which access
authorization, which user profile, and/or which authorization
profile a cleaning apparatus is used.
[0085] The display information and/or the status and/or operating
information are preferably transmittable in real time from the
communication unit to the accessory.
[0086] Provision may be made for the cleaning apparatus to be
operable without a separate authentication device. For example, the
cleaning apparatus can be put into operation by any user. A main
switch is preferably provided on the cleaning apparatus or on the
accessory for switching on and switching off the cleaning
apparatus.
[0087] Alternatively, provision may be made for an authentication
device to be required for operating the cleaning apparatus. The
authentication device may be configured in a variety of ways. For
example, an object-dependent authentication may be provided, an
authorization means being associated with the cleaning apparatus as
such, for example in the form of a mechanical or electronic key.
Alternatively or in addition, a person-dependent authentication
device may be provided, the identity of the user being checked for
use with the cleaning apparatus. It is hereby possible, in
particular, to give a user access to selected cleaning apparatuses
if there are a plurality of cleaning apparatuses. The
person-dependent authentication is possible e.g. using biometric
characteristics of the user, for example checking a fingerprint,
facial recognition, iris recognition etc.
[0088] Provision may be made for an emergency cleaning operation to
be performable with the cleaning apparatus in the absence of an
authentication device or a valid authentication. For example, the
use of at least one selected predetermined function of the cleaning
apparatus is possible if no authentication device is present or if
the authentication required therewith fails.
[0089] In a preferred embodiment, in order to prevent unauthorized
access to the cleaning apparatus, said cleaning apparatus is
associated with at least one authentication device by means of
which an access authorization required for the operation of the
cleaning apparatus is providable thereto. The access authorization
can be checked for validity, for example by the control unit, the
accessory, or an external data processing device. Only then can the
cleaning apparatus be used to a predetermined or predeterminable
extent, the aforementioned emergency cleaning operation
notwithstanding.
[0090] The transmission of the access authorization to the cleaning
apparatus may, in the present case, be equivalent to the cleaning
apparatus receiving unlocking information indicating that a user
may put the cleaning apparatus into operation, in dependence on an
existing access authorization.
[0091] The access authorization may be constituted in a variety of
ways. For example, it may consist in a password, a code, an
alphanumeric character string, a biometric characteristic of the
user, a physical property of an authorization means like, for
example, a profiling with raised portions and/or recessed portions
etc.
[0092] In a preferred embodiment, the access authorization of the
cleaning apparatus is transmittable contactlessly, in particular to
the communication unit. This enables a user-friendly interaction
with the cleaning apparatus. "Contactless" presently does not
exclude that the authentication device, for example an
authorization means thereof, has a physical contact with the
cleaning apparatus. The contactless transmission takes place e.g.
by radio, for example by way of an existing Bluetooth connection of
the accessory with the communication unit, by way of an RFID
connection, an NFC connection, for example optically or by means of
a magnetic or electrical field effect.
[0093] Alternatively, provision may be made for the access
authorization of the cleaning apparatus to be transmittable in a
contact-based manner. In particular, the access authorization can
be physically sensed, for example when using a mechanical key that
is arranged in a corresponding receptacle of the cleaning
apparatus.
[0094] It is advantageous if the cleaning apparatus comprises a
receptacle in which the authentication device is releasably
arrangable. The receptacle is favorably arranged on the operating
unit. The authentication device has a defined position in the
receptacle, the access authorization being able to be reliably
transmitted to the cleaning apparatus or sensed thereby in a
contactless or contact-based manner. The authentication device may
be fixable in the receptacle, for example by means of force fit
and/or positive engagement, in particular clampingly and/or
latchingly. The presence of the authentication device can
preferably be automatically detected. For example, a sensor element
that can cooperate with the authentication device in a contactless
or contact-based manner may be provided for this purpose. The
receptacle, when the accessory is used as an authentication device,
may in particular be the receptacle on the operating unit
associated with said accessory.
[0095] In a preferred embodiment, provision is made for the access
authorization to be saved on the authentication device in a storage
unit. The access authorization can be read from the storage unit
and can preferably be transmitted contactlessly to the cleaning
apparatus.
[0096] Alternatively or in addition, provision may be made for the
access authorization to be physically stored on the authentication
device, for example in the form of the aforementioned profiling
with raised portions and/or recessed portions.
[0097] In a preferred embodiment, the access authorization may
preferably be inputtable by the user on the authentication device
by means of an input device and be transmittable to the cleaning
apparatus, in particular to the communication unit. For example, an
input device of the accessory, in particular a touchscreen, is used
to input the access authorization. Said access authorization can,
for example, be checked for validity by the accessory, by the
control unit, or an external data processing device.
[0098] It is favorable if the accessory comprises or forms an
authentication device. This makes it possible, in particular, to
use an accessory that users carry with them like, for example, a
smartphone or a tablet computer not only for providing the image
display, but also for unlocking the cleaning apparatus.
[0099] Alternatively or in addition, provision may be made for an
authorization means formed separate from the accessory to comprise
or form an authentication device. For example, an electronic or
mechanical key may be used as an authorization means.
[0100] The authorization means may be configured e.g. as a
transponder in which the access authorization is saved. The access
authorization is preferably transmitted to the cleaning apparatus
wirelessly, for example by means of RFID technology.
[0101] Provision may be made for an authorization means, as
described above, formed separate from the accessory to be used when
using the authentication via said accessory.
[0102] It is favorable if a user profile is provided. This enables
an individualization of the cleaning apparatus in which, for
example, presettings of the cleaning apparatus and/or the accessory
can be performed in dependence on the user profile. The user
profile is, for example, defined by a user account that can be
created and managed by an overseer or an administrator of at least
one cleaning apparatus.
[0103] It is favorable if an authorization profile is provided,
wherein two or more different authorization profiles are provided,
wherein different functional scopes are providable to a user by the
cleaning apparatus in dependence on the authorization profile. This
makes it possible to completely or partially limit or unlock the
use of the cleaning apparatus in dependence on the respective
authorization profile. Alternatively or in addition, the scope of
interaction with the cleaning apparatus that is usable on the
accessory can preferably be limitable or unlockable, for example
the scope of the user application program discussed in the
following.
[0104] A common authorization profile may be assigned to a
plurality of users. For example, an authorization profile for users
with a normal amount of experience may be created, an authorization
profile for experienced users, an authorization profile for
overseers, and an authorization profile for administrators or
service personnel. By limiting the functional scope in dependence
on the authorization profile, in particular the operational safety
of the cleaning apparatus can be increased. For example, the
authorization profile allows only a usage within the scope of the
knowledge of the user and/or of the cleaning tasks assigned to
him/her. This preferably makes it possible to prevent damage to the
cleaning apparatus, to the object to be cleaned, and/or personal
injury as a result of misuse.
[0105] An authentication device linked to an authorization profile
favorably has an identification device with an identification,
wherein the identifications of different authorization profiles
differ from one another. This enables an identification of the
authentication devices on the level of the authorization profile,
as is explained in the publications WO 2012/016847 A1 and WO
2012/013575 A1 stated at the outset.
[0106] Authorization levels may in particular be tiered
hierarchically, wherein a higher order authorization level makes it
possible to use the cleaning apparatus in a functional scope of a
lower order authorization profile and to additionally perform at
least one further function of the cleaning apparatus.
[0107] Provision may favorably be made for the user profile and/or
the authorization profile to be associated with the access
authorization. For example, a user profile is linked to the
identity of the user. In addition, an authorization profile
associated with the user or only with the access authorization may
be provided.
[0108] Provision may be made, for example, for the authorization
profile to not be linked to the user profile. For example, the
cleaning apparatus can be put into operation by way of an
authentication device. The user can also log in on the cleaning
apparatus with a user profile, for example by way of the
accessory.
[0109] Provision may be made for the user profile and/or the
authorization profile to be [0110] stored or saved in or on the
authentication device; [0111] saved in a storage unit of the
cleaning apparatus; [0112] saved in a storage unit of a data
processing device arranged externally to the cleaning apparatus. In
this case, a data connection to the data processing device can be
established e.g. by means of the authentication device and/or the
cleaning apparatus. This enables, in particular, reading out the
user profile and/or the authorization profile and directly or
indirectly transmitting the same to the cleaning apparatus, for
example in order to set the functional scope thereof as well as to
perform any presettings. For example, the user logs in on the data
processing device by way of the authentication device, in
particular the accessory, whereupon the access authorization or a
corresponding unlocking information together with the user profile
and/or an authorization profile is transmitted to the cleaning
apparatus.
[0113] In particular, provision may be made for display information
with corresponding image contents to be providable to the image
display in dependence on the user profile. For example, by way of
the user profile, the user can influence the manner in which the
display contents are displayed and/or influence a display
language.
[0114] Alternatively or in addition, preferably a presetting of at
least one functional unit of the cleaning apparatus can be
performed in dependence on the user profile, in particular an
operating parameter of at least one cleaning tool can be set. For
example, operating parameters of the functional unit that are
typically used by the user can be saved by way of the user profile
and be preset in dependence thereon.
[0115] In dependence on the authorization profile, provision may be
made, for example, for access authorizations, user profiles, and/or
authorization profiles to be able to be created or deleted. For
example, performing such functions is reserved for overseers or
administrators.
[0116] In dependence on the authorization profile, provision is
made, for example, for an adaptation of user profiles and/or
authorization profiles to be able to be carried out. For example,
an unlocking of a functional unit of the cleaning apparatus for use
can be granted or revoked. Alternatively or in addition, for
example a presetting of at least one functional unit of the
cleaning apparatus can be performed. For example, presettings for
the cleaning apparatus with a higher order authorization can be
performed, or limits for operating parameters of at least one
functional unit can be defined. It is possible that certain
operating parameters of a functional unit can also be changed with
a lower order authorization, whereas a change to certain operating
parameters is only possible with a higher order authorization.
[0117] Depending on the authorization profile, it may be possible,
for example, to create a report on the usage of the cleaning
apparatus. This possibility exists, for example, only with a higher
order authorization profile. The report can preferably be
transmitted to an external data processing device for evaluation
and/or archiving.
[0118] In dependence on the authorization profile, provision may be
made regarding the extent to which the usage data of the cleaning
apparatus can be evaluated. For example, the evaluation is only
possible with a higher order authorization profile and is not
possible for users with a lower order authorization profile.
[0119] The cleaning apparatus may be configured in a variety of
ways and, associated therewith, the makeup of the at least one
cleaning tool or cleaning assembly. The functional units of the
cleaning apparatus mentioned at the outset may be made up in a
variety of ways.
[0120] For example, the cleaning apparatus is a floor cleaning
apparatus, in particular a scrubber vacuum, a sweeping machine, or
a suction sweeping machine.
[0121] The cleaning apparatus may be a hand-guided cleaning
apparatus or a ride-on or stand-on cleaning apparatus.
[0122] It is conceivable for the cleaning apparatus to be
configured to be self-propelled and self-steering in order to be
able to perform an autonomous cleaning of the floor surface in the
absence of the user.
[0123] The cleaning apparatus may be a cleaning apparatus that
cleans with a cleaning jet, in particular a high-pressure cleaning
appliance or a dry ice blasting appliance.
[0124] As mentioned at the outset, the present invention also
relates to a cleaning system. A cleaning system in accordance with
the invention, which achieves the object stated at the outset,
comprises a cleaning apparatus of the kind stated above and at
least one accessory that has a display device with an image display
and is removably positionable in the receptacle, wherein display
information for being displayed on the image display is
transmittable to the accessory positioned in the receptacle.
[0125] The advantages which were already mentioned in conjunction
with the description of the cleaning apparatus in accordance with
the invention can also be achieved with the cleaning system.
Reference is made to the preceding remarks in this regard.
[0126] Advantageous embodiments of the cleaning system result from
advantageous embodiments of the cleaning apparatus.
[0127] The accessory is e.g. a smartphone or a tablet computer.
[0128] It is favorable if the accessory comprises a touch-sensitive
display device for accepting operating instructions of the user, in
particular a touchscreen.
[0129] A user application program is preferably executably saved on
the accessory, for example a so-called "App". Operating
instructions for the cleaning apparatus are favorably providable by
the user by way of the user application program, which instructions
are transmittable from the accessory to the communication unit. It
is thereby possible for the user to use the accessory not only for
the display of image contents on the image display, but also for
inputting operating instructions by way of an input device, in
particular the aforementioned touchscreen.
[0130] The operating instructions advantageously comprise settings
of at least one operating parameter of a functional unit of the
cleaning apparatus. Alternatively or in addition, the operating
instructions may comprise, for example, the creating and/or
changing of access authorizations, user profiles, and/or
authorization profiles for users, and/or the creating of reports on
the usage of the cleaning apparatus.
[0131] It is understood that the input of an access authorization
by way of the input device of the accessory can presently be
interpreted as an operating instruction.
[0132] It is favorable if by way of the user application program,
at least one digital operating element is providable on the display
device for accepting operating instructions, which operating
element is preferably configured identically or corresponding to a
functionally identical physical operating element of the operating
unit. In this way, physical operating elements can be recreated or
duplicated, as it were. This makes it possible for the user using
the accessory to operate the cleaning apparatus in an intuitive
manner, wherein learned operating patterns or hand grips can be
applied with the accessory. Moreover, the versatility is increased
by the user being able to select the manner of interaction with the
cleaning apparatus that is most comfortable to him/her.
[0133] Provision may be made for at least one digital operating
element to be providable on the display device for accepting
operating instructions, the operating unit comprising no
corresponding physical functionally identical operating element.
Instead of a conventional operating element, now an operating
element on the accessory in digital form is used. This enables a
"streamlining", so to speak, of the cleaning apparatus, wherein a
user can, at least in part, carry the operating unit with him/her,
as it were, for example in the form of the smartphone or the tablet
computer.
[0134] A communicative connection to an externally arranged data
processing device can advantageously be established by way of the
accessory and/or the communication unit. This makes it possible,
for example, to forward reports on the usage of the cleaning
apparatus and/or a transmission of information regarding the access
authorization, the user profile, and/or the authorization
profile.
[0135] The cleaning system preferably comprises a data processing
device arranged externally to the cleaning apparatus and to the
accessory. "Data processing device" presently includes the case
that a plurality of data processing devices in communicative
connection with one another may be present, for example implemented
as a "Cloud".
[0136] The cleaning system may comprise a plurality of cleaning
apparatuses and a plurality of accessories. The cleaning
apparatuses and/or the accessories may each be of identical or
different configuration.
[0137] The present invention also relates to a cleaning system with
an authentication device.
[0138] A cleaning system in accordance with the invention comprises
a cleaning apparatus of the aforementioned kind or a cleaning
system of the aforementioned kind and at least one authentication
device by way of which an access authorization is providable to the
cleaning apparatus.
[0139] Reference is made to the above statements regarding the
advantages achievable herewith and preferred embodiments.
[0140] FIG. 1 shows an advantageous embodiment of a cleaning system
in accordance with the invention, attributed as a whole with the
reference numeral 10. The cleaning system 10 comprises at least one
preferred embodiment of a cleaning apparatus in accordance with the
invention, attributed with the reference numeral 12.
Advantageously, further cleaning apparatuses 12 are provided,
depicted schematically, which may differ from the cleaning
apparatus 12 with regard to type and/or configuration.
[0141] The cleaning system 10 further comprises at least one
authentication device 14. Here, presently four authentication
devices 14 are depicted. The authentication devices 14 are
configured for use with the cleaning apparatus 12.
[0142] The same applies to at least one accessory 16 of the
cleaning system 10, which may be used together with the cleaning
apparatus 12. For example, two accessories 16 are depicted, namely
one as a smartphone 18 and the other as a tablet computer 20.
[0143] The cleaning system 10 comprises a spatially remote data
processing device 22 that is arranged externally to the cleaning
apparatus 12 and the accessories 16. In the present case, only one
data processing device 22 is depicted. It is understood that the
cleaning system 10 may comprise a plurality of data processing
devices 22 that are in communicative connection with one another.
This is presently depicted by a "Cloud" 24.
[0144] The accessories 16 may be in a communicative connection with
the data processing device 22, for example by way of a cellular
network and/or a data network like the internet. Further, provision
may be made for the cleaning apparatus 12 to also be able to
establish a communicative connection for exchanging data with the
data processing device 22. For this purpose, the data processing
device 22 presently comprises a communication unit 26 (FIG. 2). The
communication unit 26 is, for example, integrated into, formed by,
or in operative connection with a control unit 28 of the cleaning
apparatus 12.
[0145] The cleaning apparatus 12, in the present example, is a
walk-behind cleaning apparatus. The cleaning apparatus 12 is, in
particular, a scrubber vaccum 30 for cleaning a floor surface
32.
[0146] It was already mentioned at the outset that the invention
may also be used with cleaning apparatuses of a different type, for
example sweeping machines, suction sweeping machines, jet cleaning
appliances like high-pressure cleaning appliances or dry ice
blasting appliances. It is favorable if the invention is applied to
user-guided cleaning apparatuses (walk-behind and ride-on), which
are guided by a user walking, standing, or sitting.
[0147] The cleaning apparatus 12 is used for cleaning the floor
surface 32, which is presently considered to be oriented
horizontally, wherein a contact plane of the cleaning apparatus 12
coincides with the plane of the floor surface 32. In its intended
use, the cleaning apparatus 12 is moved in a working direction that
is defined by the longitudinal direction 34. A transverse direction
36 of the cleaning apparatus 12 is defined transverse to the
longitudinal direction 34.
[0148] The cleaning apparatus comprises on a rear side 38, in
relation to the longitudinal direction 34, an operating unit 40 for
the user walking therebehind. The operating unit 40 is arranged in
the transition from the rear side 38 to a top side 42.
[0149] The cleaning apparatus 12 comprises a plurality of
functional units 44 for performing a function. Operating
instructions of the operating person on the operating unit 40 can
be processed and transmitted to the functional units 44 by the
control unit 28.
[0150] For example, a cleaning tool 46 that comprises a cleaning
brush and, in particular, a plate brush 48 as well as a drive
device 50 for the plate brush 48 is presently provided as a
functional unit 44. Provided as a further functional unit 44 is a
pressing device 52 with which a pressing force of the plate brush
48 against the floor surface 32 can be set.
[0151] Provided as further functional units 44 are a chassis 54
with a drive device 56 for moving the cleaning apparatus 12 over
the floor surface 32 and a suction assembly 58 with which a mixture
of dirt and cleaning liquid can be suctioned from the floor surface
32.
[0152] Further functional units 44 are a dosing device 60 with
which the amount of cleaning liquid accommodated in a tank 62 for
acting on the floor surface 32 can be dosed, as well as a cleaning
agent dosing device 64 for dosing a cleaning chemical admixed to
the cleaning liquid.
[0153] The tank 62 is formed by a housing 66 that comprises a
housing part 68 at the top. The housing part 68 forms a lid 70 of
the tank 62 and is mounted so as to be pivotable about a horizontal
pivotal axis 72 presently extending in the transverse direction 36
(FIG. 3). For opening the tank 62, the lid 70 can be pivoted
backwards about the pivotal axis 72 from a closed position into an
open position (not shown) in the direction of the operating unit
40.
[0154] The operating unit 40 has a gripping device 74 for making it
easier for a user to guide the cleaning apparatus 12. The gripping
device 74 presently comprises two gripping elements 76. The
gripping elements 76 are presently configured as stirrup-shaped
longitudinal gripping elements, which are spaced at a distance from
one another in the transverse direction 36.
[0155] The user can rest his/her hands 78 on the gripping elements
76 in the longitudinal direction without having to rotate the wrist
in the transverse direction. The hands 78 thereby lie with the
thenar eminence against the gripping elements 76, the thumbs 80
able to abut approximately from the base of the thumb 82 to the
distal ends 84. This is depicted with the example of the operating
unit 40 in the embodiment in accordance with FIGS. 8 and 9 and also
applies to the embodiment in accordance with FIGS. 1 to 4.
[0156] In the transverse direction 36, a strip 86 is thereby
defined between a connecting line, imagined in the transverse
direction 36, of the distal ends 84 on the one side and the base of
the thumbs 82 on the other side. This strip 86 is also depicted in
FIG. 3.
[0157] The operating unit 40 presently comprises a plurality of
operating elements, by way of which the user can interact with the
cleaning apparatus 12, in particular for controlling the functional
units 44.
[0158] In the transverse direction 36 laterally next to a
respective gripping element 76, facing toward the respective other
gripping element 76, the operating unit 40 comprises a rocker
lever-shaped operating element 88. By way of the operating element
88, the chassis 54 can be acted on for setting the speed and/or the
direction with which or in which the cleaning apparatus 12
travels.
[0159] Further, the operating unit 40 comprises an operating field
90 that preferably defines an operating plane 92 (FIG. 4). The
operating plane 92 is arranged on the operating unit 40 facing
toward the user and is inclined relative to the horizontal in the
direction of the user. The inclination is e.g. about 20.degree. to
30.degree. and enables the user to more easily actuate operating
elements arranged on the operating field 90.
[0160] Arranged in the operating field 90 is an operating element
94, presently a main operating element. The operating element 94
comprises a rotary grip 96 and serves as a main switch as well as
program selector switch for the cleaning apparatus 12. By way of
the operating element 94, different cleaning programs can be set,
which differ from one another in the functioning of at least one of
the functional units 44.
[0161] Moreover, further operating elements 98 are schematically
depicted, as well as two operating elements 100. By way of the
operating elements 100, values for operating parameters of at least
one functional unit 44 can be incremented or decremented. For
example, the rotational speed of the plate brush 48 can be
increased or decreased or the contact pressure for the plate brush
48.
[0162] The operating unit 40 further comprises an integrated
display device 102 installed in the operating field 90. Operational
and status information of the cleaning apparatus 12 can be
displayed on the display device 102 in order to facilitate the
operation of said cleaning apparatus 12 for a user.
[0163] The accessories 16 that can be used with the cleaning
apparatus 12 each comprise a display device 104, which in
particular has an image display 106. The image display 106 defines
an image plane.
[0164] In the present example, the accessories 16 are configured in
flat design, which is advantageous for the invention but is not
absolutely necessary.
[0165] The accessories 16 can enter into a communicative connection
with the cleaning apparatus 12. In particular, data can be
contactlessly exchanged between the accessories 16 and the
communication unit 26. This is presently understood to mean that
the data exchange itself takes place without physical contact.
However, as explained in the following, in particular, there may be
a physical contact of the accessory 16 itself with the operating
unit 40.
[0166] Alternatively or in addition, provision may be made for data
to be able to be transmitted between the communication unit 26 and
the accessory 16 in a contact-based manner, for example by way of a
wired connection not depicted in the drawing.
[0167] The cleaning apparatus 12 has a receptacle 108 arranged on
the operating unit 40 for the accessory 16. The accessory 16 can be
positioned in the receptacle 108 and thereby has a defined position
relative to the operating unit 40. Depending on the size of the
receptacle 108, a placement of the smartphone 18 and the tablet
computer 20 with the image display 106 oriented in landscape format
and/or in portrait format is possible. FIGS. 2 to 4 show the
arrangement of the smartphone 18 with the image display 106 in
landscape format, though the smartphone 18 could also be placed
with the image display 106 in portrait format.
[0168] With respect to the tablet computer 20, the receptacle 108
is presently dimensioned such that the arrangement thereof with the
image display 106 in portrait format is possible.
[0169] It is favorable if the receptacle 108 is dimensioned in such
a way that accessories 16 with a width of at least about 15 cm,
preferably up to about 25 cm and/or with a diagonal of the image
display 106 up to at least about 10 inches can be accommodated.
[0170] The receptacle 108 is positioned in the transverse direction
36 between the gripping elements 76 and between the operating
elements 88, with respect to a viewing direction of the user toward
the receptacle 108 and in particular the image display 106 of the
accessory 16 positioned in the receptacle 108. However, the
receptacle 108 is arranged on the operating unit 40 offset in a
direction away from the user relative to the gripping elements 76.
This may presently be understood to mean that the receptacle 108 is
arranged lower on the operating unit 40 (FIG. 4).
[0171] The receptacle 108 comprises an abutment element 110 that is
presently configured as a bearing element 112. The bearing element
112 is of flat configuration and is planar so that the accessory 16
is able to abut thereagainst in surface to surface contact.
[0172] The receptacle 108 further comprises a shoulder 114 that is
formed by way of a bar 116 formed projecting from the bearing
element 112. This makes it possible for the accessory 16 to be
arranged in a defined position in two spatial directions relative
to the receptacle 108.
[0173] In the present case, the bearing element 112 is formed by a
frictional coefficient-increasing element 120 or such a one is
positioned in the receptacle 108. The frictional
coefficient-increasing element 120 comprises, in particular, a mat
122 made of an elastically deformable material, for example a
rubber material. By way of the mat 122, the accessory 16 is
effectively protected from moving in the receptacle 108. In
addition, vibrations during the operation of the cleaning apparatus
12 are dampened in order to largely avoid movements of the
accessory 16 as a result of shaking.
[0174] The bearing element 112 defines an abutment and, in
particular, bearing plane 124. In the case of the accessory 16 in
flat design, the image plane of the image display 106 is oriented
in parallel to the abutment plane 124 and has only small distance
therefrom.
[0175] The abutment plane 124 is oriented at an angle 126 relative
to the operating plane 92 (FIG. 4). The angle 126 is e.g. about
10.degree. to 30.degree., for example about 20.degree.. The
abutment plane 124 is thereby inclined relative to the operating
plane 92 in the direction of the user, thus making the image
display 106 easier for the user to see.
[0176] The reference numeral 128 symbolizes a surface normal of the
abutment element 110, said surface normal having e.g. an angle of
about 45.degree. relative to the horizontal. In this way, the image
display 106 can be seen very well by most users, the viewing
direction being oriented substantially perpendicular to the image
display 106 (FIG. 5).
[0177] Provision may be made for the receptacle 108 to be movably
arranged on the operating unit 40. For example, the receptacle 108
is pivotable relative to the operating unit 40 about a pivotal axis
130 extending in a transverse direction. A discrete or a continuous
pivoting is possible, in particular the abutment element 110 being
able to be pivoted with the shoulder 114. FIGS. 6 and 7 show an
example of this for two further pivotal positions of the receptacle
108.
[0178] The orientation of the surface normal 128 is changed as a
result of the pivoting. This makes it possible, for example, to
orient the position of the accessory 16 in dependence on the size,
the position, and/or the viewing direction of a user, such that
said user always has a best possible view of the image display
106.
[0179] It is understood that the receptacle 108, which is not
depicted in the drawing, could also be pivoted in the opposite
direction, corresponding to the depictions in FIGS. 5 and 7, i.e.
counterclockwise in FIGS. 5 to 7.
[0180] Overall, the accessory is arranged, at least partially,
within the strip 86 and within the field of view of the user in
order facilitate the view of the image display 106. During the
operation of the cleaning apparatus 12, the user typically looks
across the operating unit 40 and the lid 70, standing behind the
same, such that the image display 106 can be always been seen well
during the cleaning operation.
[0181] It is favorable if the accessory 16 is positioned on the
operating unit 40 with an offset in relation to a gripping plane
132 defined by the gripping elements 76. The offset between the
gripping plane 132 and the abutment plane 124 is e.g. about 10 cm
to 15 cm. As a result of the offset, the likelihood is reduced that
the user unintentionally comes into contact with the accessory 16,
the accessory 16 being reliably arranged in the receptacle 108 even
when the user is interacting with the operating unit 40.
[0182] The operating field 90 is arranged in front of the
receptacle in the direction of the user. When interacting with the
operating elements 94, 98, or 100, the likelihood is also reduced
that the user unintentionally comes into contact with the accessory
16.
[0183] The receptacle 108 is arranged between legs 134 of the
gripping elements 76, the legs 134 pointing in the direction of the
respective other gripping element 76 and being arranged on the
sides of the gripping elements 76 facing away from the user.
[0184] The receptacle 108 is preferably positioned on the operating
unit 40 in such a way that the lid 70 adopting the open position is
free of contact with the receptacle 108 and preferably free of
contact with the accessory 16. This is favorably independent of
whether the accessory 16 is positioned in the receptacle 108 with
the image display 106 in landscape format or in portrait
format.
[0185] The positioning of the accessory 16 in the receptacle 108 as
well as the removal thereof is possible, in particular, manually
and without tools. The accessory 16 is held sufficiently reliably
in the receptacle 108 by way of frictional engagement, in
particular by means of the mat 122, and positive engagement by way
of the bearing element 112 and the shoulder 114.
[0186] For communicating with the cleaning apparatus 12, in
particular the communication unit 26, the accessory 16 can enter
into a communicative connection of different kinds. In particular,
a Bluetooth connection may be used, though the invention is not
limited to this.
[0187] A user application program is executably saved on the
accessory 16, for example a so-called "App". Display information
relating to the operation of the cleaning apparatus 12 can be
transmitted by way of the communication unit 26 to the accessory 16
and there be displayed, in particular using the App (FIG. 3).
[0188] Provision may thereby be made for the information
displayable on the image display 106 to differ from the information
that is displayed on the permanently installed display device 102.
It is also conceivable for the information on the display devices
102 and 104 to complement one another.
[0189] In particular, provision may be made for the display device
102 to be deactivated when the accessory 16 is positioned in the
receptacle 108. The presence of the accessory 16 may, for example,
be detected contactlessly or in a contact-based manner. For
example, a sensor element 136 is provided on the receptacle 108 for
contactlessly detecting the accessory 16.
[0190] In a preferred embodiment, the display device 102 is
deactivated when the user positions the accessory 16 in the
receptacle 108. Display information is transmitted to the accessory
16 to be displayed on the image display 106. If the user removes
the accessory 16 from the receptacle 108, no further transmission
of display information occurs, and the display device 102 is
controlled to display information.
[0191] By way of the permanently installed display device 102, it
is ensured that visual information is displayed to the user even if
he/she is not carrying an accessory 16.
[0192] By way of the user application program, an interface is
provided for the user to interact with the cleaning apparatus 12.
In a preferred embodiment, the user application program may provide
e.g. digital operating elements, referenced as a whole with the
reference numeral 138. In the present case, a digital variant of
each of the operating elements 94, 98, and 100 is displayed on the
display device 104. The display device 104 is touch-sensitively
configured as a touchscreen, by means of which operating
instructions of the user can be accepted by way of the accessory 16
and transmitted by the same to the communication unit 26.
[0193] The operating elements 138 are functionally identical to the
operating elements 94, 98, and 100, such that the user can operate
the cleaning apparatus 12 by means of the digital operating
elements 138 without having to adjust his/her learned habits and
abilities.
[0194] It is understood that the user application program, for the
purpose of interacting with the cleaning apparatus 12, can provide
the user different or further operating elements, for example
menus, input fields, selection lists, toggles, etc.
[0195] In an advantageous embodiment of the cleaning apparatus in
accordance with the invention, it is conceivable for the cleaning
apparatus to not comprise a functionally identical, physical
operating element relating to a digitally provided operating
element 138 on the display device 104. Provision may be made for
this to be the case for the majority or all operating elements of
the operating unit 40, in the present case for example for
operating elements 88, 94, 98, and 100.
[0196] It is also conceivable for a physical operating element of
the operating unit 40 to be deactivated when the accessory 16 is
positioned in the receptacle 108 and a corresponding digital
operating element 138 is provided on the display device 104.
[0197] An authentication device 14 is required for the operation of
the cleaning apparatus 12. An access authorization is provided to
the cleaning apparatus 12 by way of the authentication device 14.
Provision may be made for an emergency operation to be able to be
performed with the cleaning apparatus 12 in the absence of an
authentication device 14 or in the case of failed
authentication.
[0198] In the present case, authentication devices 14 are present,
which are configured as authorization means 140 in the form of
electronic keys, specifically authorization means 140a, 140b, 140c,
and 140d. The authorization means 140 are, in particular,
transponders, which are able to contactlessly interact with the
cleaning apparatus 12 by means of RFID technology.
[0199] Otherwise, in the scope of the present invention, a
contactless interaction, for example by way of a different radio
connection, and/or a contact-based interaction, for example by
physically sensing an access authorization, may be provided.
[0200] For positioning an authorization means 140 in a defined
manner, the cleaning apparatus 12 comprises a receptacle 142
arranged on the operating unit 40. The authorization means 140 can
be releasably positioned in the receptacle 142 and preferably
clampingly and/or latchingly fixed therein.
[0201] In the present case, an RFID reader 144 is provided, which
is arranged within reach of the receptacle 142. When the
authorization means 140 is located in the receptacle 142, the
presence thereof can be detected by means of the RFID reader 144.
For example, the RFID reader 144 repeatedly sends read pulses,
which are received by the authorization means 140 when arranged in
the receptacle 142 and can be replied to.
[0202] The authorization means 140 comprises a storage unit in
which an access authorization, for example in the form of an ID or
a code, is saved. The access authorization can be contactlessly
detected by the RFID reader 144, transmitted to the control unit
28, and checked for validity by said control unit 28. If the result
of the check is positive, the cleaning apparatus 12 is
unlocked.
[0203] Alternatively, it is conceivable for unlocking information
to be transmitted to the cleaning apparatus 12 in dependence on the
access authorization. For example, the detected access
authorization is transmitted via the communication unit 26 to the
data processing device 22 and is checked for validity by said data
processing device 22. If the result is positive, unlocking
information for unlocking the cleaning apparatus 12 can be
transmitted.
[0204] The authorization means 140 presently differ in that the
access authorization is linked to different authorization profiles.
For example, an authorization means 140a is provided for users with
a normal amount of experience and an authorization means 140b for
more experienced users. An authorization means 140c is provided
e.g. for overseers and an authorization means 140d for
administrators or service personnel.
[0205] In dependence on the authorization profile of the respective
authorization means 140a to 140d, a different functional scope is
provided to the user by the cleaning apparatus 12. In particular,
the authorization profiles may be defined as authorization levels
that are structured hierarchically.
[0206] The functional scope for a user with a normal amount of
experience is typically smaller than for a more experienced user,
and the functional scope accessible to that user not as wide as the
functional scope provided to an overseer. The widest functional
scope with the authorization means 140d is provided for
administrators.
[0207] Information on the authorization profile are stored e.g. in
the storage unit of the authorization means 140, in the cleaning
apparatus 12, and/or in the data processing device 22. Provision
may be made for the respective authorization profile to be able to
be determined solely by identifying the access authorization.
[0208] In addition, provision is made for user-individual user
profiles to be provided in the cleaning system 10. Said user
profiles are managed e.g. by way of user accounts that are saved,
in particular, in the data processing device 22, alternatively or
in addition in the accessory 16 and/or the cleaning apparatus
12.
[0209] For example, the user can log into his/her user account by
way of the App of the accessory so that the user profile can be
provided for the operation of the cleaning apparatus 12.
[0210] Provision may be made for the user to be able to connect to
the cleaning apparatus 12 with his/her user profile by way of the
accessory 16, though the startup (aside from the possible emergency
operation mentioned above) is possible only once an authorization
means 140 is used.
[0211] For example settings preferred by the user for functional
units 44 are stored in the user profile, provided they can be made
by the user. Alternatively or in addition, the user can define in
the user profile, for example, which display information he/she
would like to have displayed on the image display 106. The language
of the image display 106 is preferably also saved in the user
profile.
[0212] If the user profile is known, presettings can be made for
the user of the functional units 44 in order to make it easier for
the user to put the cleaning apparatus 12 into operation.
[0213] As mentioned, the functional scope that is provided to the
user is defined by the authorization profile and therefore by the
use of the respective authorization means 140a to 140d. The user
can use the cleaning apparatus 12 within the extent of the
functional scope, wherein in dependence on the authorization
profile, for example: [0214] access authorizations, user profiles,
and/or authorization profiles can be created or deleted; [0215] an
adaptation of user profiles and/or authorization profiles can be
performed, in particular regarding an unlocking of a functional
unit 44 for use and/or a presetting of at least one functional unit
44 of the cleaning apparatus 12; [0216] a report on the usage of
the cleaning apparatus 12 can be created and preferably transmitted
to an external data processing device 22; [0217] usage data of the
cleaning apparatus 12 can be evaluated.
[0218] Provision may thus be made for the user to have no access or
only limited access to certain functional units 44. For example,
the user can use functional units 44, the operating parameters of
which do not change or change only within certain limits.
[0219] By using the authorization profiles, it can be ensured that
the operational safety can be increased for the protection of the
cleaning apparatus 12, the user, the object to be cleaned, or third
parties, because the functional scope can be tailored to the
abilities of the user, his/her trustworthiness, and the cleaning
tasks that are to be performed.
[0220] In a concrete example, provision is made e.g. for the user
with a normal amount of experience to be able to change the travel
speed, the rotational speed of the plate brush 48, and the dosing
via the dosing device 60 and/or the cleaning agent dosing device
64, wherein presettings can be providable and storable by way of
the user profile. However, the normal user is subject, for example,
to the limitation that the travel speed can only be changed within
certain limits, and that another operating parameter, for example
the contact pressure by way of the pressing device 52, is not able
to be changed at all.
[0221] Changing the functional scopes that are linked to an
authorization means 140 may be reserved e.g. for an overseer using
the authorization means 140c or an administrator using the
authorization means 140d.
[0222] Alternatively or in addition, the image content of the image
display 106 may be different in dependence on the functional scope.
For example, the display information differs regarding which
authorization means 140 is used. Lower order authorization profiles
obtain e.g. no access to certain menus or setting elements that are
reserved for higher order authorization profiles.
[0223] Provision may be made, for example, for information about a
consumable component to be displayed on the image display 106.
Again depending on the authorization profile, provision may be made
for the placing of an order, for example in the case of wear to a
consumable component (e.g. the plate brush 48), to be reserved for
users with a certain authorization profile. A user with a lower
order authorization profile, however, is only able, for example, to
forward information about the supply of a consumable component to
be replaced.
[0224] The use of the user profiles and/or authorization profiles
enables e.g. tracking which user or which group of users is using
one or more cleaning apparatuses 12.
[0225] Cleaning tasks can be individualized and, for example,
assigned to a particular user. Alternatively or in addition, the
cleaning tasks may be assigned in dependence on an existing
authorization profile, for example only to normal users or only to
overseers. It should hereby be considered, for example, that the
user is typically in possession of an authorization means 140 that
corresponds to his/her actual authorization profile.
[0226] For example, in dependence on the authorization profile of
the user, information can be transmitted to the accessory 16 and
displayed on the image display 106. For example, the user is
instructed to change or to check the cleaning tool 46, wherein this
task, for example, should only be performed by experienced users or
overseers.
[0227] FIG. 3a shows in a detail view in a manner corresponding to
FIG. 3 a plan view of the operating unit 40 with a cleaning
apparatus in accordance with the invention.
[0228] The receptacle 108 additionally comprises at least one
holding element, preferably two holding elements 146, with which
the accessory 16 can be held on the receptacle 108 even more
reliably.
[0229] In the present case, the holding elements are configured as
bars that have an angling (for example L-shaped) and project from
the bearing element 112. An interspace 148 in the manner of a
"compartment" is thereby formed between the bars and the bearing
element 112. The accessory 16 can be slid into the interspace 148,
presently from above.
[0230] In the case of vibrations that are transmitted to the
accessory 16, the holding elements 146 ensure that the accessory 16
does not lift up and, in the worst case, fall out of the receptacle
108.
[0231] FIGS. 8 and 9 show in a manner corresponding to FIG. 3 the
operating unit 40 of an advantageous embodiment, only partially
depicted and designated with the reference numeral 150, of a
cleaning apparatus in accordance with the invention, which could be
used in a cleaning system in accordance with the invention together
with the cleaning apparatus 12 or in place thereof.
[0232] Identical reference numerals are used for like or
functionally equivalent features and components. This also applies
to the following embodiments. The advantages that can be achieved
with the cleaning apparatus 12 can also be achieved with the
cleaning apparatus 150 as well as with the cleaning apparatuses
discussed in the following. Only the most important differences are
described.
[0233] In the cleaning apparatus 150, for example fewer operating
elements are arranged on the operating field 90; only the operating
element 94 is provided.
[0234] The receptacle 108 is arranged in the region of the
operating field 90 above or behind the operating element 94. The
accessory 16 in the form of the smartphone 18 is thereby arranged
entirely or substantially entirely within the strip 86 both when
the image display 106 is oriented in the landscape format as well
as in the portrait format and thereby is easily visible in the
field of view of the user (FIG. 8). The accessory 16 in the form of
the tablet computer 20 is, for example, positioned mostly within
the strip 86 when the image display 106 is oriented in the portrait
format (FIG. 9).
[0235] The permanently integrated display device 102 is also
provided in the case of the cleaning apparatus 150, and arranged in
the region of the receptacle 108. Provision may be made, for
example, in order to clear the view of the display device 102, for
the mat 122 to be dimensioned smaller than in the case of the
cleaning apparatus 12 or for the mat 122 to have a cutout.
[0236] When the accessory 16 is arranged in the receptacle 108, the
display device 102 is covered by said accessory 16 and is
deactivated. The user in this way concentrates his/her optical
perception on the image display 106. When the accessory 16 is
removed, view of the display device 102 is cleared and the same is
activated to provide visual information for the user.
[0237] Schematically depicted in FIGS. 10 to 12 is in each case an
operating unit 40 of a cleaning apparatus 152, 154 and 156,
respectively, in accordance with the invention. In the case of the
cleaning apparatuses 152 to 156, a respective charging device 158
is provided with which the accessory 16 is applied with electrical
energy and the usage time thereof can thereby be increased.
[0238] In the case of the cleaning apparatus 152 in accordance with
FIG. 10, the charging device 158 is of inductive configuration and
is arranged on the side of the abutment element 110 facing away
from the accessory 16. When the accessory 16 is arranged in the
receptacle 108, the battery thereof can be charged.
[0239] The charging device 158 in the case of the cleaning
apparatus 154 in accordance with FIG. 11 comprises at least one and
preferably a plurality of fixedly arranged electrical connecting
element(s) 160 (for example configured as a docking connector). The
connecting element 160 can couple to a corresponding electrical
connecting element of the accessory 16.
[0240] In the case of the cleaning apparatus 156 in accordance with
FIG. 12, the charging device 158 comprises a charging cable 162
with connecting element 164 for connecting to the connecting
element of the accessory 16. Provision may further be made for a
connector socket 166 for connecting a charging cable to be
present.
[0241] It is understood that a preferred embodiment of the cleaning
apparatus in accordance with the invention may comprise two or more
of the different variants of the charging device 158 described
above.
[0242] A preferred embodiment, depicted in FIG. 13, of a cleaning
system in accordance with the invention is designated with the
reference numeral 170.
[0243] The data processing device 22 is omitted in the case of the
cleaning system 170. User profiles are stored e.g. on the
accessories 16 and/or in the cleaning apparatus 12. The
authorization profiles are preferably saved on the authorization
means 140 linked to the access authorizations.
[0244] A preferred embodiment, depicted in FIG. 14, of a cleaning
system in accordance with the invention is designated with the
reference numeral 180.
[0245] The authentication devices 14 in the form of the
authorization means 140 are omitted in the cleaning system 180.
Instead, the accessories 16 each form an authentication device
14.
[0246] For putting the cleaning apparatus 12 into operation, the
access authorization can be inputted by the user on the accessory
16 via the app or it is determined in dependence on a user account.
The access authorization may be transmitted to the cleaning
apparatus 12 for unlocking. Alternatively, provision may be made
for the access authorization to be transmitted to the data
processing device 22 by way of a data connection and for a
corresponding unlocking information to be transmitted directly or
indirectly to the cleaning apparatus 12 by said data processing
device 22.
[0247] The user profiles and the authorization profiles may be
saved in the cleaning apparatus 12, in the accessory 16, and/or in
the data processing device 22. In particular, there is preferably a
link between the access authorization and the user profile and the
authorization profile.
[0248] If an access authorization is detected to be valid, the
cleaning apparatus 12 can be switched on, the functions allowed for
by the corresponding authorization profile being able to be
performed. User-defined settings can be loaded e.g. by way of the
user profile.
[0249] In the case of the cleaning system 180, authorization
profiles can be managed e.g. by way of the user application program
of an accessory 16. While in the case of the cleaning system 10 and
170 the authorization profile is defined by the respective
authorization means 140a to 140d, this makes it possible in the
case of the cleaning system 180 for user profiles, in particular
hierarchical user levels, to be more easily and more flexibly
managed.
[0250] Conversely, by using the authorization means 140, the
required expenditure required for managing authorization profiles
on the software level can be saved. This may be advantageous, for
example, if there are high fluctuations in the users of the
cleaning apparatus 12.
[0251] A preferred embodiment, depicted in FIG. 15, of a cleaning
system in accordance with the invention is designated with the
reference numeral 190.
[0252] As in the case of the cleaning system 170, the data
processing device 22 is omitted in the cleaning system 190. As in
the case of the cleaning system 180, the authentication devices 14
in the form of the authorization means 140 are omitted. In all
other respects, the cleaning system 190 corresponds to the cleaning
system 180 without the property that data can be exchanged between
the external data processing device 22 and the cleaning apparatus
12 and/or the accessories 16.
