BACKGROUND OF THE INVENTION
[0002] The invention relates to a household appliance with at least
one control element for modifying at least one operating parameter
of the household appliance. The invention further relates to a
method for operating a household appliance.
[0003] It is known that if a control element which is provided for
modifying at least one operating parameter of the household
appliance is not operated correctly, an operator or user must reset
this operating parameter. The difficulty which arises in such cases
is that the operator frequently no longer remembers the value of
the operating parameter set incorrectly by the incorrect operation
of the control element. It can even occur that a number of
operating parameters are set incorrectly by the incorrect operation
of a control element, which further complicates making a new
setting.
[0004] The task of the present invention is to overcome the
disadvantages of the prior art, at least in part.
BRIEF SUMMARY OF THE INVENTION
[0005] This object is achieved by the features of the independent
claims. Preferred embodiments are especially to be taken from the
dependent claims.
[0006] The object is achieved by a household appliance with a least
one control element for modifying at least one operating parameter
of the household appliance. The household appliance also has at
least one reset control element which is intended for resetting at
least one most recently carried out modification. This gives the
advantage that the operator no longer has to remember the
incorrectly set value but merely needs to actuate the reset control
element in order to return the value to its original setting. Such
resetting is also able to be executed especially easily, especially
with a few actuations.
[0007] A control element can for example be understood as a
physical control element, e.g. a switch, a button, a slider etc.,
or also a control panel of a sensor array etc. for example.
[0008] The reset control element can especially be embodied as a
separate switch or button. The switch or the button might be a
physical switch or button or might for example be a control area of
a sensor array. The reset control element might be one function of
a multifunction button.
[0009] The resetting of at least one modification recently carried
out can include the resetting of just one modification, the last
one carried out.
[0010] One embodiment is that the reset control element is
configured for resetting a number of recently carried out
modifications, e.g. the last two, three or more modifications
carried out. The resetting of a number of modifications can for
example be undertaken by actuating the reset control element just
as frequently and/or by a longer-duration actuation of the reset
control element if the reset control element is equipped with what
is referred to as a repeat function.
[0011] Another embodiment is that a modification of the at least
one operating parameter is undertaken as a result of precisely one
actuation of an associated control element.
[0012] Another embodiment is that the at least one operating
parameter is modified as a result of a number of consecutive
actuations of the at least one control element, wherein two
actuations carried out directly one after the other do not extend
beyond a predetermined period of time. This enables series of
actuations which are carried out one after the other in a
sufficiently rapid sequence to be canceled or reset with a single
actuation of the reset control element. In such cases the content
relationship between these actuations is established by the
sufficiently rapid sequence, wherein the "sufficiently rapid"
sequence is determined by the first predefined period of time.
[0013] A further embodiment is that the predefined period of time
amounts to at least approximately one second, especially at least
approximately three seconds, especially approximately five
seconds.
[0014] A further embodiment is that a modification is able to be
reset up to a second predefined period of time. The advantage
achieved by this is that a reset is only carried out for changes
which do not lie too far back and consequently make little sense
for a current situation. For example by switching off a heat
setting of a cooking device a temperature of the cooked item might
have cooled down so far after five minutes that simply resetting it
to its previous state would no longer produce a satisfactory
cooking result.
[0015] A development is that the second predefined period of time
lies between thirty seconds and ten minutes, especially lasts for
at least one minute, especially approximately five minutes.
[0016] A development is that the second predefined period of time
is dependent on an operating state and/or a modification of the
operating state of the household appliance. Thus the household
appliance can recognize this operating state (e.g. on the basis of
operating parameters set) and automatically assign an associated
second predefined period of time, especially assigned automatically
by the household appliance. This makes possible an especially
effectively assigned resetting. For example the second predefined
period of time can be set for a cooktop as a function of a value of
a heat setting before a modification, after the modification and/or
of the extent of the modification.
[0017] Another embodiment is that a modification is able to be
reset after the household appliance is switched off up to a third
predefined period of time, which is especially shorter than the
second predefined period of time. The provision of the third
predefined period of time prevents a household appliance
deliberately switched off and switched back on again much later
being reset to operating parameter values before it was switched
off.
[0018] A development is that the third predefined period of time
amounts to a maximum of around one minute. For example the
household appliance can in this way be switched back on after a
switch off before the third period of time is reached or exceeded
and can be reset by means of the reset control element again at
least to the state obtaining before the switch-off.
[0019] The domestic appliance can be switched on and reset to the
operating parameter values valid before the switch-on for example
by actuating the main switch and then the reset control element or
by actuating only the reset control element (especially within the
third predefined period of time). These alternatives are especially
also provided for the case in which the switching off has been
carried out automatically especially after a long continuous
actuation has been identified.
[0020] A further development is that modifications made during
normal operation are able to be reset by means of the reset control
element. Normal operation can especially be understood as operation
between switching on and switching off the household appliance. A
specific development is that only modifications made during normal
operation are able to be reset. In this case in particular
modifications made after switching off the household appliance may
no longer be reset, for example since an associated memory or
memory area is erased with the switching off.
[0021] An embodiment is also that specific modifications
(especially modifications of specific parameters) are able to be
reset and other modifications (especially modifications of other
parameters) are not able to be reset. This enables the resetting to
be designed in an even more user-friendly way. This exploits the
fact that a few operating parameters are able to be reset simply
and intuitively, while resetting of other operating parameters is
either able to be carried out just as easily with other means or
does not make possible any resetting that can be implemented
intuitively.
[0022] A development is that modifications of an operating
parameter are especially able to be reset if this operating
parameter can assume more than two values. That an operating
parameter can assume more than two values can especially mean that
it includes an operating parameter range, e.g. a number of heat
settings. However modifications of an operating parameter which can
assume two or fewer values can basically also be reset.
[0023] The non-resettable modifications can especially include
modifications which activate or switch in a function (e.g. activate
a roasting sensor system) or trigger a sequence (e.g. starting a
timer or of automatic programming). The non-resettable
modifications can especially include modifications which are only
used for appliance control (e.g. triggering of a "select" button or
a menu button).
[0024] Another embodiment is that a resetting by the reset control
element is only then able to be initiated if there is no incorrect
actuation present. Thus a new modification following on directly
from the resetting can be avoided because of the non-rectified
incorrect actuation function.
[0025] A development is that a resetting by the reset control
element is only then able to be initiated if there is no incorrect
actuation of a resettable control element present. The reset
control element might thus trigger and a resetting might however be
carried out if an incorrect actuation of a non-resettable control
element is present.
[0026] A development is also that the incorrect actuation is a
permanent actuation. In such cases it is assumed that a specific
control element does not have to be actuated for longer than a
fourth predefined period of time and/or usually is not actuated for
longer than the fourth predefined period of time. If a specific
control element is actuated for as long as or for longer than the
fourth predefined period of time, an incorrect actuation is
assumed. This permanent actuation can for example be created by
laying objects on the at least one control element or if
electrically conductive liquid, e.g. noodle water, spills onto a
capacitively-responsive sensor array. Another type of incorrect
actuation, depending on operational control, might comprise a
simultaneous actuation of a number of control elements for
example.
[0027] Another embodiment is that the reset control element is
coupled to a memory device, wherein the memory device is configured
to store the at least one modification made most recently. This
makes a simple resetting possible. The memory device might be a
memory device assigned permanently to the reset control element for
example or might be present as a memory area of a memory unit of a
central control unit of the household appliance.
[0028] A development is to restore the at least one modification
with a respective actuation of the resetting control element (and
to do so into a memory or into memory areas in which the values of
the operating parameters are able to be stored or are stored during
operation of the household appliance). The restoring makes an
especially simple resetting implementation possible.
[0029] A development is that at least one operating parameter is
able to be modified automatically and with each (i.e. also an
automatic) modification which it undergoes, is able to be stored or
is stored. This also enables operating parameters which change over
time to be reset to values valid immediately before a modification
and not just to originally set values. Such a modification can also
be an automatic modification of the operating parameter.
[0030] The at least one predefined operating parameter can include
at least one ongoing period of time, especially a timer time and/or
a cooking time.
[0031] A general development is also that only modifications which
have been made by a manual actuation of a control element are able
to be reset. Modifications made automatically, e.g. an automatic
countdown of a period of time executed by a control device, are
consequently not able to be reset by an actuation of the reset
control element in such cases. In particular a change in a manual
and automatically modifiable operating parameter might only be able
to be reset if the modification has been made manually and
otherwise the value of the operating parameter is only updated.
[0032] A further embodiment is that a storage of a modification is
able to be deleted automatically (i.e. is deleted or is not even
made at all) if the associated at least one operating parameter has
not been modified by the modification. This might be the case for
example for a modification of an operating parameter in which a
target value corresponds to an initial value. This enables storage
space to be saved and an operator is not confused during resetting
by not recognizing any change on actuating the reset control
element.
[0033] A development is that the storage of a modification is able
to be erased automatically if the associated at least one operating
parameter, without taking into account at least one modification
carried out automatically, has not been changed by the
modification. The storage of the modification is thus also able to
be erased automatically if, since the last, modification undertaken
manually, an operating parameter has automatically changed its
setting.
[0034] The household appliance can basically comprise any household
appliance, especially a cooking appliance, especially a cooker.
[0035] Another embodiment is that the household appliance is a
cooker in the form of a cooking appliance with a cooktop. The
invention is able to be implemented advantageously particularly for
this embodiment, since many settings are specifically made and also
modified during a cooking process.
[0036] For a cooking appliance in particular the following
modifications are able to be reset for example: an adjustment of a
heat setting, an adjustment of a zone switch-in, an adjustment of
start to boil setting (especially its activation, if necessary also
a period of time and/or a level) and/or an adjustment (including
activation) of a timer time.
[0037] For example the following modifications might not be able to
be reset: an activation of a time, an activation of a roasting
sensor system, an activation of an automatic program, an activation
of a selection/menu button, an activation of a child lock, an
activation of a wipe protection (especially by an actuation of a
respectively assigned control element) and/or an activation of the
at least one hot plate by actuating the main switch.
[0038] Another development is that with a resetting of the at least
one operating parameter an associated display of the value of the
parameter is reset, if present. The display can e.g. be an
alphanumeric display and/or a symbol display.
[0039] The object is achieved by a method for operating a household
appliance, wherein at least one modification of an operating
parameter recently carried out is able to be reset by an
operator.
[0040] The method produces the same advantage as the household
appliance and can also be embodied in a similar way. Thus the
modification might be able to be carried out by means of actuating
a reset control element. The at least one modification might also
be able to be reset during normal operation.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS OF THE PRESENT
INVENTION
[0049] FIG. 1 shows an overhead view of a section of a cooktop 1 of
a cooking device G (e.g. a range cooker or a stand-alone cooktop)
looking at a control panel 2, wherein the control panel 2 is in a
first actuation state. Shown above the control panel 2 are two of a
total of four hotplates 3a-d able to be operated by the control
panel 2. The control panel 2 is embodied for example as a
capacitive sensor array and has a number of (sensor) buttons 4,
5a-d, 6a-d, 7 to 13 arranged in a row and also display panels 14a-d
and 15.
[0050] Individually these are a main switch 4 for switching the
cooktop 1 on and off, arranged at a left-hand edge. In this case
the cooking device G can continue to be supplied with power, e.g.
to display an error condition, but at least the hot plates 3a, 3c
are switched off.
[0051] Located to the right next to the main switch 4 is a
reduction button or "-" button 5a for reducing the heat setting of
the cooktop 3a. The heat setting can be reduced here for example
between "9" (maximum power) and "0" (cooktop switched off) in full
steps or half steps and/or also in predefined steps. The "-" button
5a has the repeat function, i.e. it reduces multiple times when
actuated continuously.
[0052] Located to the right next to the "-" button 5a is an
increase button or "+" button 6a to increase the heat setting of
the cooktop 3a, maximally between "0" and "9". The "+" button 6a
also has a repeat function, i.e. it increases the setting multiple
times when actuated continuously.
[0053] Located to the right next to the "+" button 6a is a child
lock button 7, which on actuation of a child lock suppresses
actuation of the other buttons 4, 5a-d, 6a-d, 8 to 13. The child
lock can be canceled again by actuating the child lock button 7
once again.
[0054] Located on the right next to the child lock button 7 are a
"-" button 5b and a "+" button 6b, which are able to be actuated or
function in a similar way to the "-" button 5a and the "+" button
6a, however now for the hot plate 3b located behind the hotplate
3a.
[0055] Located on the right next to the "+" button 6b are, in this
order, a decrement timer button or"-" timer button 8, a timer
activation button 9 and an increment timer button or "+" timer
button 10. The timer activation button 9 enables a timer to be
activated and the "-" timer button 8 and the "+" timer button 10
enable it to be adjusted, especially also decremented or
incremented, possibly with a repeat function.
[0056] Located on the right next to the "+" timer button 10 are a
"-" button 5c and a "+" button 6c, which are able to be actuated or
function in a similar way to the "-" button 5a and the "+" button
6a, but now for the hotplate 3c.
[0057] Located on the right next to the "+" button 6c is a zone
addition button 11, with which a hotplate expansion or cooking zone
is able to be added to a hotplate, e.g. the hotplate 3d located
behind the hotplate 3c.
[0058] Located on the right next to the zone addition button 11 are
a "-" button 5d and a "+" button 6d, which are able to be actuated
or function in a similar manner to the "-" button 5a and the "+"
button 6a, but now for the hotplate 3d located behind the hotplate
3c.
[0059] Located on the right next to the "+" button 6c is a heat
boost supplementary switch 12, with which a heat boost is able to
be activated.
[0060] Located on the right next to the heat boost supplementary
switch 12, and thus on the right-hand edge of the control panel 2,
is a reset control element in the form of a reset button 13.
[0061] Located above the buttons 4, 5a-d, 6a-d, 7 to 13 are the
display panels 14a-d and 15, and from left to right they are in
this order: a single-segment display 14a for displaying a heat
setting of the hotplate 3a, a single-segment display 14b for
displaying a heat setting of the hotplate 3b, a two-digit timer
display 15 for displaying the current timer time, a single-segment
display 14c for displaying a heat setting of the hotplate 3c and a
single-segment display 14d for displaying a heat setting of the
hotplate 3d.
[0062] In the first actuation state shown the cooktop 1 is switched
on, and hotplate 3a is at a heat setting of "9", hotplate 3b is
performing a supplementary heat boost "A", hotplate 3c is at a heat
setting of "7" and hotplate 3d is switched on, but is at a heat
setting of "0". A zone connection for the hotplate 3d is active
(associated lamp not shown).
[0063] By actuating the "+" button 6d, as indicated by the arrow in
the diagram below the control panel 2, the heat setting of hotplate
3d can be increased from "0" to "9" and this can be done by a
corresponding frequent actuation of the "+" button 6d or by use of
the repeat function. The "+" button 6d (like the "+" buttons 6a to
6c), for a first actuation after the cooktop 1 is switched on, can
set the heat setting to a predefined level and only on a subsequent
actuation increase the heat setting in turn. Such a modification of
an operating parameter, because of its sufficiently rapid sequence,
counts as a single modification.
[0064] The correspondingly adjusted state of the operating panel 2
and thus also of the cooktop 1 is shown in FIG. 2. Now, as
indicated by the arrow, the heat setting of the cooktop 3d can be
reduced to "8" by at least a single, short actuation of the "-"
button 5d, which is shown in FIG. 3. Subsequently the timer can be
set by an actuation of the timer button 9, through which the timer
display 15 is initially set to "00", which is shown in FIG. 4. The
time can be incremented by actuating the "-" timer button 8 from
the "00" in 10 steps or in other predefined time steps (e.g. to a
value "10", as shown in FIG. 5) and through an (especially
multiple) actuation of the "+" timer button 10 be adjusted in
individual steps (steps of one minute) (e.g. to a value of "17", as
shown in FIG. 6).
[0065] Due to the unintentional switching down of the heat setting
of the hotplate 3d shown by the arrow in FIG. 6 by rapid
consecutive actuations or made possible by the repeat function
because of a corresponding actuation of the "-" button 5d, not only
is the heat setting of the hotplate 3d adjusted, but also timers
and possibly a previously activated zone addition are deactivated
for this hotplate 3d. This is designed as a single modification.
With this modification a number of operating parameters are thus
modified by an actuation of just one actuation element.
[0066] Through the following actuation of the reset control element
13, as indicated by the arrow in FIG. 7, the modifications created
by the last actuation of the "-"-button 5d are cancelled or reset,
namely the associated heat setting of the hotplate 3d to "8", the
timer is activated and again set to a value "17", as already shown
in FIG. 6. The displays 14d and 15 are reset accordingly.
[0067] Actuating the reset control element 12 once more could
enable further modifications (in the reverse order in which they
were made) to be reset, e.g. the timer is then reset again to the
value "10" etc. In such cases it is assumed that the changes made
between the figures shown have been performed with an interval
between them which is larger than a predefined first period of time
of three seconds here for example.
[0068] Were the timer function already started, wherein the timer
time is counted down by the cooking device G independently in
minutes, and were the unintentional actuation of the "-" button 5d
then to occur, by the actuation of the reset button 13 the
associated heat setting of the hotplate 3d would be reset to "8",
the timer activated and reset to the then current value (which can
also be smaller than "17").
[0069] Naturally the present invention is not restricted to the
exemplary embodiment shown.
[0070] Thus the invention is not restricted to sensor arrays.
[0071] The control panel can also have further characteristics,
e.g. illustrated in the general description part.
[0072] Then, starting from FIG. 1, a switching-off of the main
switch is undertaken (all hotplates to heat setting "0", i.e.
switched off, corresponding segment displays 14a-d to display "0",
timer display 15 deactivated, no additional functions such as a
zone addition, a timer or a supplementary heat boost activated), by
actuating the reset button 13 the setting of the cooktop 1 in
accordance with FIG. 1 can be restored or reset, if the reset
button 13 is actuated within five minutes, possibly only after a
renewed actuation of the main switch 4.
