DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
[0037] Hereinafter, the present disclosure will be described in
more detail with reference to the accompanying drawings.
[0038] FIG. 1 is a diagram illustrating a network system according
to an embodiment of the present disclosure.
[0039] Referring to FIG. 1, a network system 1000 may include a
plurality of electronic devices 10 to 50, and a server 100.
[0040] Here, the plurality of electronic devices 10 to 50 are
electronic devices that constitute a home network or the Internet
of Things (IoT) environment, and are connected to various kinds of
networks to communicate with each other or to communicate with the
server 100.
[0041] In this case, the plurality of electronic devices 10 to 50
and the server 100 may use various communication types to be
connected to the network. For example, the plurality of electronic
devices 10 to 50 and the server 100 may be connected to the network
using various kinds of wireless communications, such as Wi-fi
(Wireless fidelity), BT (Bluetooth), and cellular communication
(e.g., LTE, LTE-A, CDMA, WCDMA, UMTS, WiBro, or GSM), or various
kinds of wired communications, such as USB (Universal Serial Bus),
HDMI (High Definition Multimedia Interface), RS-232 (Recommended
Standard 232), and POTS (Plain Old Telephone Service). However,
this is merely exemplary, and the communication types are not
limited thereto.
[0042] Under such an environment, in order to improve user
convenience and to provide an optimum dry state for laundry, a
dryer 20 may receive washing information of a washing machine 10,
and perform drying of the laundry through setting of a drying
course of the laundry using the washing information.
[0043] FIG. 2 is a block diagram illustrating the configuration of
a washing machine according to an embodiment of the present
disclosure.
[0044] Referring to FIG. 2, a washing machine 10 includes a
communicator 11 and a processor 12.
[0045] The communicator 10 may be connected to a network to
communicate with a plurality of electronic devices 20 to 50 and a
server 100. For this, the communicator 11 may include various kinds
of communication modules for being connected to the network through
wired communication or wireless communication.
[0046] The processor 12 controls the whole operation of the washing
machine 10. For this, the processor 12 may include a CPU (Central
Processing Unit) (or microcomputer), a RAM (Random Access Memory)
and a ROM (Read Only Memory) for the operation of the washing
machine 10.
[0047] First, the processor 12 may acquire washing information for
laundry. Here, the washing information may include at least one of
a laundry weight, a water content rate, a washing course, a washing
temperature, a washing time, a dehydration time, and the degree of
dehydration.
[0048] For this, the washing machine 10 may be provided with
various sensors installed therein.
[0049] Specifically, the washing machine 10 may include a weight
sensor for measuring the weight of laundry, specifically, the
weight of laundry of which washing and dehydration have been
completed, a temperature sensor for measuring the temperature of
air in a drum or the temperature of the laundry after completion of
the washing, and a humidity sensor for measuring a moisture content
rate (i.e., water content rate) of the laundry.
[0050] Accordingly, the processor 12 may determine the weight of
laundry, the water content rate, and the washing temperature based
on sensed values measured by various sensors.
[0051] Further, the processor 12 may acquire information on a
washing course for laundry.
[0052] In general, the washing course is set in the washing machine
to wash the laundry based on an appropriate amount of water, an
amount of detergent, a washing intensity, a washing time, a
dehydration time, a dehydration intensity, and whether to dehydrate
in accordance with the kind and the weight of the laundry.
[0053] For example, the washing course may include a standard
washing course for washing laundry having general materials and
sizes, a wool course for washing woolen laundry, a bedding washing
course for washing bed clothes having a large volume, such as a
quilt or a blanket, and a special washing course for washing
laundry of a functional material, such as mountain climbing wear or
sportswear.
[0054] In this case, a user may select a washing course in
accordance with the kind of laundry that the user intends to wash
to perform washing.
[0055] Accordingly, the processor 12 may determine information on
the washing course for laundry through determination of the washing
course selected by the user when washing the laundry.
[0056] Further, the processor 12 may acquire information on the
washing time, the dehydration time, and the degree of
dehydration.
[0057] Specifically, the processor 12 may determine information on
the washing time and the dehydration time of the laundry through
determination of the washing time and the dehydration time using
time that is consumed from the time when the washing and the
dehydration start to the time when the washing and dehydration is
completed. Further, the processor 12 may determine the degree of
dehydration of the laundry through determination of RPM
(Revolutions Per Minute) of a motor that rotates the drum during
the dehydration.
[0058] Through the above-described method, the processor 12 may
acquire the washing information of the laundry.
[0059] Further, if the washing and dehydration of the laundry is
completed, the processor 12 may control the communicator 11 to
transmit the washing information that is acquired during the
laundry washing and dehydration process to the server 100.
[0060] In this case, the processor 12 may transmit the washing
information of the laundry to the server 100 whenever the washing
and dehydration of the laundry is completed.
[0061] That is, since washing of another laundry can be performed
after washing of a specific laundry is completed, the processor 12
may transmit washing information of a specific laundry to the
server 100 after the washing and dehydration of the laundry is
completed, and if the washing and dehydration of another laundry is
completed, the processor 12 may transmit the corresponding washing
information of the laundry to the server 100.
[0062] Although not illustrated, the washing machine 10 may further
include additional constituent elements.
[0063] For example, the washing machine 10 may include a tub
installed in a main body to contain water (washing water or rinsing
water), a cylindrical drum rotatably installed in the tub, a motor
rotating the drum to perform washing, rinsing, and dehydration of
laundry, a door installed on a front portion of the main body to
put laundry into the drum or to take out the laundry in the drum, a
water supply pipe for supplying water into the tub, a water
discharge pipe for discharging water in the tub to an outside, a
control panel including various kinds of buttons for receiving an
input of a user command for controlling the washing machine and a
display, and a storage storing various kinds of programs for
driving the washing machine 10, such as programs for the respective
washing courses.
[0064] Since the above-described constituent elements are those
that are generally used for the washing and dehydration of the
laundry, the detailed explanation thereof will be omitted.
[0065] On the other hand, the server 100 may provide the washing
information that is received from the washing machine 10 to the
dryer 20. This will be described in more detail hereinafter.
[0066] FIG. 3 is a block diagram explaining constituent elements of
a server according to an embodiment of the present disclosure.
[0067] Referring to FIG. 3, a server 100 includes a communicator
110, a storage 120, and a processor 130.
[0068] The communicator 110 may be connected to a network to
communicate with a plurality of electronic devices 20 to 50. For
this, the communicator 110 may include various kinds of
communication modules for being connected to the network through
wired communication or wireless communication.
[0069] The storage 120 stores various pieces of data. For this, the
storage 120 may be implemented by various types of storage media,
such as RAM, ROM, EEPROM, and hard disk.
[0070] Specifically, the storage 120 may store washing information
that is received from a washing machine 10, and this will be
described later.
[0071] The processor 130 controls the whole operation of the server
100. For this, the processor 130 may include a CPU (Central
Processing Unit) (or microcomputer), a RAM (Random Access Memory)
and a ROM (Read Only Memory) for the operation of the server
100.
[0072] First, if the washing information of the washing machine 10
is received through the communicator 110, the processor 130 stores
the received washing information in the storage 120. That is, the
processor 130 may operate to receive and store the washing
information of the washing machine 10 that is connected to the
network.
[0073] Then, the processor 130 transmits the pre-stored washing
information to a dryer 20 through the communicator 110.
[0074] Specifically, if a transmission request command of the
washing information is received from the dryer 20, the processor
130 may transmit the pre-stored washing information to the dryer
20. However, this is merely exemplary, and the processor 130 may
also transmit the washing information to the dryer 20 at a time
when the washing information is received from the washing machine
10 or at a time when a predetermined time elapses after the washing
information is received. In addition, the processor 130 may
transmit the washing information to the dryer 20 at any time that
may be variously determined.
[0075] On the other hand, if a plurality of pieces of washing
information are pre-stored, the processor 130 may transmit the
plurality of pieces of washing information to the dryer 20, or may
transmit the washing information, which is received from the
washing machine 10 within a predetermined time before the
transmission request command of the washing information is received
among the plurality of pieces of washing information, to the dryer
20.
[0076] That is, as described above, if the washing is performed
several times, the washing machine 10 may transmit a plurality of
pieces of washing information to the server 100, and the processor
130 may transmit all or a part of the plurality of pieces of
washing information to the dryer 20.
[0077] In particular, since drying of the laundry is performed just
after the washing is completed, the processor 130 may transmit the
washing information, which is received from the washing machine 10
within a predetermined time before the transmission request command
of the washing information is received among the plurality of
pieces of washing information, to the dryer 20 in consideration of
the time in which the laundry is moved to the dryer 20.
[0078] However, this is merely exemplary, and the processor 130 may
transmit the washing information that is selected in accordance
with a user command to the dryer 20.
[0079] For this, the processor 130 may control the communicator 110
to transmit the pre-stored washing information to electronic
devices 30, 40, and 50 connected to the network. In this case, the
electronic devices 30, 40, and 50 may display the washing
information through displays provided therein, and if the user
command for selecting the washing information is input, they may
transmit this to the server 100. Accordingly, the processor 130 may
determine the washing information selected by the user, and
transmit the selected washing information to the dryer 20.
[0080] On the other hand, if the washing information is received
from the washing machine 10, the processor 130 may control the
electronic devices 30, 40, and 50 that are connected to the network
to provide notifications indicating that the washing and
dehydration of the washing machine 10 is completed.
[0081] Here, the notification may be audibly provided or visually
provided through the displays provided on the electronic devices
30, 40, and 50.
[0082] For example, as shown in FIG. 4, if the washing information
is received, the processor 130 may transmit a control command to a
TV 30 that is connected to the network so that a voice, such as
"Washing has been completed. Please move the laundry to the dryer",
is output from the TV 30. As another example, as shown in FIG. 5,
if the washing information is received, the processor 130 may
transmit a control command to a smart phone 40 that is connected to
the network so that a GUI 41 that reports completion of the washing
is output from the smart phone 40.
[0083] However, this is merely exemplary, and the notification may
be provided in various methods. For example, if the washing
information is received in a state where a lamp (not illustrated)
is connected to the network, the processor 130 may transmit a
control command for turning on the power of the lamp (not
illustrated) to notify the user of the completion of the washing
through the lamp (not illustrated).
[0084] On the other hand, if the washing information is received
from the server 100, the dryer 20 may set a drying course for
drying the laundry based on the washing information. Hereinafter,
this will be described in more detail.
[0085] FIG. 6 is a block diagram illustrating constituent elements
of a dryer according to an embodiment of the present
disclosure.
[0086] Referring to FIG. 6, the dryer 20 includes a communicator
21, a display 22, and a processor 23. However, among the
above-described constituent elements, the display 22 may be omitted
according to circumstances.
[0087] The communicator 21 may be connected to a network to
communicate with a plurality of electronic devices 10 and 30 to 50.
For this, the communicator 21 may include various kinds of
communication modules for being connected to the network through
wired communication or wireless communication.
[0088] The display 22 displays a screen. As an example, the display
22 may display various screens, such as a menu screen for selecting
washing information and a menu screen for selecting a drying
course.
[0089] The processor 23 controls the whole operation of the dryer
20. For this, the processor 23 may include a CPU (Central
Processing Unit) (or microcomputer), a RAM (Random Access Memory)
and a ROM (Read Only Memory) for the operation of the washing
machine 20.
[0090] First, the processor 23 receives washing information that is
pre-stored in a server 100 from the server 100.
[0091] Specifically, if a predetermined user command is input, the
processor 23 may control the communicator 21 to transmit a
transmission request command of washing information to the server
100 and to receive the washing information from the server 100 in
response to this. Here, the user command may include a user command
for turning on the power of the dryer 20 or a user command for
switching a mode of the dryer 20 from a standby mode to an
operation mode.
[0092] Further, the processor 23 sets a drying course for drying
the laundry that is put into the dryer 20 based on the washing
information that is received from the server 100.
[0093] For this, the processor 23 may determine drying information
that is required to determine the drying course of the laundry
based on the washing information.
[0094] Specifically, the processor 23 may determine a drying
temperature and a drying time that are required to dry laundry at
an optimum state in accordance with a laundry weight, a water
content rate, a washing temperature, a washing course, a
dehydration time, and the degree of dehydration.
[0095] For example, in order to perform an optimum drying of the
laundry, it is required to perform drying for a relatively long
time at high temperature as the weight of the laundry and the water
content rate are high, and to perform the drying for a relatively
long time at high temperature as the weight of the laundry is high
even in the case of the same water content rate. Further, in the
case of special clothes made of a functional material, in order to
perform optimum drying without damaging the clothes, it is required
to perform drying at a specific temperature for a specific
time.
[0096] Further, in order to perform optimum drying in accordance
with the weight of the laundry, it is required to perform drying at
a specific temperature for a specific time, and in the case of low
washing temperature rather than high washing temperature, it is
required to perform drying so that an initial temperature rising
width becomes high.
[0097] Further, since the water content rate becomes high in the
case where the dehydration time is short and the degree of
dehydration is low rather than in the case where the dehydration
time is long and the degree of dehydration is high, the optimum
laundry drying can be performed through drying at a relatively high
temperature for a long time in the case where the dehydration time
is short and the degree of dehydration is low.
[0098] Accordingly, the dryer 20 may pre-store information on a
drying temperature and a drying time that are required to dry the
laundry at an optimum state in accordance with a laundry weight, a
water content rate, a washing temperature, a washing course, a
dehydration time, and the degree of dehydration. On the other hand,
the information on the optimum drying temperature and drying time
may be acquired through the result of simulations during
manufacturing of the dryer 20 and may be pre-stored in the dryer
20. Further, the processor 23 may download information on the
optimum drying temperature and drying time by connecting to a
server that is operated by a manufacturer through a network, or may
periodically update the information.
[0099] Accordingly, if the washing information is received from the
server 100, the processor 23 may determine the optimum drying
temperature and drying time that are required when drying the
laundry of which the washing has been completed in the washing
machine 10 using the pre-stored information.
[0100] Further, the processor 23 may determine a drying course that
corresponds to a drying course that corresponds to the drying
information among drying courses in which at least one of the
drying temperature and the drying time differs, and perform the
drying of the laundry using the determined drying course.
[0101] That is, the dryer 20 may pre-store a plurality of drying
courses in which at least one of the drying temperature and the
drying time differs, and the processor 23 may determine a drying
course that has the optimum drying temperature and drying time that
are required when the laundry of which the washing has been
completed in the washing machine 10 among the pre-stored drying
courses, and may automatically perform the drying of the laundry
that is put into the dryer 20 using the corresponding drying
course.
[0102] As described above, according to an embodiment of the
present disclosure, the drying is performed based on the washing
information, and thus user convenience can be improved. Further,
since the drying is performed using the optimum drying course in
accordance with the weight and the dehydration state of the
laundry, incomplete drying and over-drying can be prevented from
occurring in accordance with the weight and the dehydration state
of the laundry. Further, even in the case of the special clothes,
the drying is performed using the optimum drying course that suits
the corresponding clothes, and thus damage of the clothes can be
prevented.
[0103] Although it is described that the drying of the laundry is
automatically performed based on the washing information, this is
merely exemplary, and the drying may be performed in accordance
with a user command.
[0104] Specifically, the processor 23 may control the display 22 to
display the drying course that is determined based on the drying
information, and if a user command for selecting the displayed
drying course is input, the processor 23 may perform the drying of
the laundry using the selected drying course.
[0105] In this case, the processor 23 may display a menu for
selecting another drying course except for the determined drying
course on the display based on the drying information, and perform
the drying of the laundry using the selected other drying course if
the other drying course is selected through the menu.
[0106] For example, as shown in FIG. 7, if it is determined that
the drying course of the laundry is a "special clothes course", the
processor 23 may display a menu screen 710 for inquiring whether to
perform the drying through the special clothes course on the
display 22. Accordingly, the processor 23 may perform the drying in
the special clothes course in accordance with the user command
input through the corresponding menu screen 710.
[0107] In this case, the processor 23 may also display a menu
screen 720 for inquiring whether to perform the drying in another
drying course except for the special clothes course on the display
22.
[0108] Accordingly, if a user command for performing the drying in
another drying course is input, the processor 23 may display a menu
screen 810 for selecting another drying course except for the
special clothes course as shown in FIG. 8. Accordingly, the
processor 23 may perform the drying in the drying course in
accordance with the user command that is input through the menu
screen 810.
[0109] On the other hand, although it is described that an input of
the user command is received through the dryer 20, it is merely
exemplary, and the user command may be input through another
electronic device connected to the network except for the dryer
20.
[0110] For example, the processor 23 may control the communicator
21 to transmit the information for the determined drying course. In
this case, the server 100 may transmit the information on the
received drying course to other electronic devices 30 to 50
connected to the network.
[0111] Accordingly, the electronic devices 30 to 50 may display the
drying course, and if a user command for selecting the displayed
drying course is input, they transmit this to the server 100. In
this case, the server 100 may transmit a control command for
performing the drying to the dryer 20 based on the received user
command. Accordingly, if a control command is received from the
server 100, the processor 23 may perform the drying of the laundry
in accordance with the determined drying course.
[0112] On the other hand, as described above, if the washing is
performed several times in the washing machine 10, the dryer 20 may
receive a plurality of pieces of washing information from the
server 100.
[0113] In this case, the processor 23 may determine drying
information corresponding to a plurality of pieces of washing
information received from the server 100, determine the drying
courses that correspond to the plurality of pieces of drying
information, control the display 21 to display the determined
plurality of drying courses, and perform the drying of the laundry
using the drying course that is selected in accordance with a user
command among the plurality of drying courses.
[0114] That is, even in the case where the user performs the
washing of different kinds of laundry, drying may be performed with
respect to a part of the laundry, but drying may not be performed
with respect to the remaining laundry. Accordingly, it is required
for the user to select the drying course that suits the laundry to
be dried among the plural pieces of laundry.
[0115] Accordingly, if a plurality of pieces of washing information
are received from the server 100, the processor 23 may provide the
drying courses for the plurality of pieces of washing information
to the user to enable the user to select the drying course that
suits the laundry to be dried.
[0116] On the other hand, although not illustrated, the dryer 20
may further include additional constituent elements.
[0117] For example, the dryer 20 may further include a drum
installed in the main body to contain laundry, a condensation duct
for condensing moisture in air that flows in from the drum, a
drying duct for drying the air that flows in from the condensation
duct through heating the air, a blower fan arranged between the
condensation duct and the drying duct to form an air flow so that
the air that flows into the condensation duct can flow into the
drum through the drying duct, and a storage storing various kinds
of programs for driving the dryer 20, such as programs for the
respective drying courses, to dry the laundry. On the other hand, a
heater for heating the internal air is built in the drying duct,
and a water supply nozzle is provided on the condensation duct to
supply condensation water (cold water) into the condensation duct
so that moisture is condensed and removed in a process in which
high-temperature and high-moisture air that is generated through
the drying of the laundry passes through the condensation duct.
This water supply nozzle may be connected to a condensation water
supply pipe that supplies condensed water, and the condensation
water supply pipe may be connected to a water supply valve.
[0118] FIG. 9 is a flowchart illustrating a method for controlling
a dryer according to an embodiment of the present disclosure.
[0119] First, washing information that is pre-stored in a server is
received from the server (S910). Here, the washing information may
include at least one of a laundry weight, a water content rate, a
washing course, a washing temperature, a washing time, a
dehydration time, and the degree of dehydration.
[0120] Then, a drying course for drying the laundry that is put
into the dryer is set based on the washing information (S920).
[0121] Specifically, S920 may determine drying information that is
required to determine a drying course for the laundry based on the
washing information, determine a drying course that corresponds to
the drying information among drying courses in which at least one
of a drying temperature and a drying time differs, and perform
drying of the laundry using the determined drying course.
[0122] In this case, the determined drying course is displayed on a
display provided on the dryer, and if a user command for selecting
the displayed drying course is input, drying of the laundry is
performed using the selected drying course.
[0123] Further, a menu for selecting another drying course except
for the determined drying course is displayed on the display, and
if another other drying course is selected through the menu, the
drying of the laundry is performed using the selected other drying
course.
[0124] On the other hand, S920 may determine pieces of drying
information that correspond to a plurality of pieces of washing
information received from the server, determine the drying courses
that correspond to the plurality of pieces of drying information,
control the display to display the determined plurality of drying
courses, and perform the drying of the laundry using the drying
course that is selected in accordance with a user command among the
plurality of drying courses.
[0125] Further, the server may receive the washing information from
a washing machine that is connected to the network and store the
received washing information, and if washing and dehydration of the
laundry is completed, the washing machine may transmit the washing
information that is acquired during the washing and dehydration of
the laundry to the server.
[0126] In this case, if the washing information is received from
the washing machine, the server may control an electronic device
that is connected to the network to provide a notification
indicating that the washing and dehydration of the washing machine
is completed.
[0127] On the other hand, the server may transmit the washing
information that is received from the washing machine to the dryer
within a predetermined time before a transmission request command
for the washing information is received from the dryer.
[0128] On the other hand, the method for performing drying based on
the washing information is as described above.
[0129] On the other hand, a non-transitory computer readable medium
may be provided to store therein a program for successively
performing the control method according to the present
disclosure.
[0130] A non-transitory computer readable medium is not a medium
that stores data for a short period, such as a register, a cache,
or a memory, but means a medium which semi-permanently stores data
and is readable by a device. Specifically, the above-described
programs may be stored and provided in the non-transitory computer
readable medium, such as, a CD, a DVD, a hard disc, a Blu-ray disc,
a USB, a memory card, and a ROM.
[0131] Further, in the block diagram illustrating the washing
machine, the dryer, and the server, a bus is not illustrated.
However, communication between the respective constituent elements
in the washing machine, the dryer, and the server may be performed
through the bus. Further, a processor, such as a CPU or a
microprocessor that performs the various operations as described
above, may be further included in the respective devices, and a
memory for performing the various operations as described above may
be further included in the respective devices.
[0132] Further, in the embodiments of the present disclosure, the
term "module", "unit", or "part" is to designate a constituent
element that perform at least one function or operation, and this
constituent element may be implemented by hardware or software, or
by a combination of hardware and software. Further, plural
"modules", "units", or "parts" may be integrated into at least one
module or chip, except for a case where it is necessary to
implement them as individual specific hardware, to be implemented
as at least one processor (not illustrated).
[0133] The foregoing exemplary embodiments and advantages are
merely exemplary and are not to be construed as limiting the
present disclosure. The present teaching can be readily applied to
other types of apparatuses. Also, the description of the exemplary
embodiments of the present disclosure is intended to be
illustrative, and not to limit the scope of the claims, and many
alternatives, modifications, and variations will be apparent to
those skilled in the art.
