BACKGROUND

1. Field

The disclosures relate to a washing machine, and more particularly, to a washing machine capable of communicating with a drying machine.

2. Description of Related Art

In general, a washing machine is an apparatus configured to wash laundry inside of a tub by rotating a drum rotatably installed in the tub to accommodate the laundry. The washing machine may perform a washing process using water to separate pollutants from the laundry, a rinsing process rinsing the laundry, and a dehydrating process removing water from the wet laundry.
In addition, a drying machine may include a drum that is rotatably installed, and may dry an object to be dried (laundry) by injecting high-temperature dry hot air into the drum while the drum is rotating. The drying machine may perform a drying process for drying the object to be dried.
Recently, the drying machine having a heat pump and operating only with electricity has been commercialized. As a result, restrictions on installing the drying machine have been reduced, and the number of households equipped with the washing machine with the drying machine is increasing.
For example, the drying machine may be placed side by side (horizontally) with the washing machine, or may be placed at the same position of the washing machine.
When the drying machine is placed side by side with the washing machine, a user may immediately put the washed laundry into the drying machine. However, because the drying machine is arranged side by side with the washing machine, a space occupied by the drying machine and the washing machine increases.
When the drying machine is placed on top of the washing machine, the user may immediately put the laundry into the drying machine, and the space occupied by the drying machine may be reduced similarly to using only the washing machine.
However, when the drying machine is placed on top of the washing machine, a control panel of the drying machine is located at a high position, thus the user has inconvenience in operating the drying machine.

The expression, “at least one of a, b, and c,” should be understood as including only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.
Hereinafter, the operation principles and embodiments of the disclosure will be described with reference to the accompanying drawings.
FIG. 1 is a view illustrating that a washing machine is arranged horizontally with a drying machine according to an embodiment. FIG. 2 is a view illustrating that a washing machine is arranged vertically with a drying machine according to an embodiment.
Referring to FIGS. 1 and 2 , a washing machine 100 may be disposed adjacent to a drying machine 300. As such, because the washing machine 100 is disposed adjacent to the drying machine 300, a user may move laundry from the washing machine 100 to the drying machine 300 without lifting and moving the laundry.
As illustrated in FIG. 1 , the washing machine 100 may be placed side by side (horizontally) with the drying machine 300. Because the washing machine 100 is placed side by side with the drying machine 300, the user may easily move the laundry from the washing machine 100 to the drying machine 300, as well as easily use a control panel of the washing machine 100 and a control panel of the drying machine 300. On the other hand, because the washing machine 100 is arranged side by side with the drying machine 300, the user's living space may be reduced.
Also, as illustrated in FIG. 2 , the drying machine 300 may be disposed on the washing machine 100 (vertical). The washing machine 100 usually washes laundry (for example, clothes or shoes) using water, and thus a weight of the washing machine 100 may increase significantly during a washing operation. On the other hand, the drying machine 300 dries objects to be dried (e.g., clothing or shoes, etc.) using high-temperature dry hot air, so that a weight of the drying machine 300 does not change significantly during a drying operation. Thus, the relatively light drying machine 300 (during operation) may be placed on top of the washing machine 100.
Thus, because the drying machine 300 is disposed on top of the washing machine 100, a space occupied by the washing machine 100 and the drying machine 300 may be similar to a case where the washing machine 100 is used alone. In other words, the user's living space may not be significantly reduced due to the drying machine 300. However, because the drying machine 300 is placed on top of the washing machine 100, the control panel of the drying machine 300 is placed at a high position. As a result, some of the users may have difficulty using the control panel of the drying machine 300.
In order to prevent or reduce the user from having difficulty using the control panel of the drying machine 300 when the drying machine 300 is placed on top of the washing machine 100, or in order for the user to control the drying machine 300 and the washing machine 100 collectively when the drying machine 300 is placed side by side with the washing machine 100, the washing machine 100 may provide a user interface for controlling the drying machine 300 using the control panel of the washing machine 100. In other words, the user may control the drying machine 300 using the control panel of the washing machine 100.
In order for the washing machine 100 to provide the user interface for controlling the drying machine 300, the washing machine 100 may communicate with the drying machine 300 either by wire or wirelessly. For example, the washing machine 100 may not only obtain washing settings (e.g., washing temperature, number of rinsing times, dehydrating strength, etc.) for the washing operation from the user, but also obtain drying settings (e.g., degree of drying, additional time for preventing or reducing wrinkles, drying time, etc.) for the drying operation from the user. In addition, the washing machine 100 may transmit the drying settings obtained from the user to the drying machine 300 by wire or wirelessly, and the drying machine 300 may dry an object to be dried depending on the drying settings received from the washing machine 100.
FIG. 3 is a view illustrating a side cross-section of a washing machine according to an embodiment.

The air discharge-type drying machine may refer to a drying machine which sucks outside air, uses the outside air in drying, and then discharges the outside air to the outside of the drying machine.
The drying machine 300 may include the fan 340 configured to circulate air inside the drum 330. The fan 340 may suck air from inside the drum 330 and discharge the air to the duct 350. By the fan 340, the air inside the drum 330 may circulate through the drum 330 and the duct 350. The fan 340 may rotate by the fan motor 345.
The heater 355 and the heat pump 360 may be provided in the duct 350 through which the air inside the drum 330 circulates.
As illustrated in FIG. 12 , the heat pump 360 may include a compressor 361, a condenser 362, an evaporator 364, and an expander 363. The compressor 361, the condenser 362, the expander 363, and the evaporator 364 may be seated at a bottom surface of the cabinet 301.
The compressor 361 may compress refrigerant in a gaseous state to a high-temperature, high-pressure state and discharge the gaseous refrigerant in the high-temperature, high-pressure state. The discharged refrigerant may be transferred to the condenser 362.
The condenser 362 may condense the compressed gaseous refrigerant to a liquid. The condenser 362 may dissipate heat to surrounding portions thereof through the process of condensing the refrigerant. The condenser 362 may be provided in the duct 350 and heat the air through heat generated in the process of condensing the refrigerant. The liquid refrigerant condensed by the condenser 362 may be transferred to the expander 363.
The expander 363 may expand the high-temperature, high-pressure liquid refrigerant condensed by the condenser 362 to the liquid refrigerant in a low-pressure state. For example, the expander 363 may include an expansion valve configured to adjust a pressure difference of the refrigerant.
The evaporator 364 may evaporate the liquid refrigerant expanded by the expander 363. As a result, the evaporator 364 may cause the low-temperature, low-pressure gaseous refrigerant to return to the compressor 361.
The evaporator 364 may absorb heat from the surrounding portions thereof through an evaporation process in which the low-pressure liquid refrigerant is changed to the gaseous refrigerant. The evaporator 364 may be provided in the duct 350 and may cool air passing through the evaporator 364 in the evaporation process.
Air around the evaporator 364 may be cooled by the evaporator 364, and, when a temperature of the air around the evaporator 364 becomes lower than the dew point, the air around the evaporator 364 may be condensed. Due to the condensation occurring around the evaporator 364, the absolute humidity of the air passing through the evaporator 364 may be lowered. In other words, the amount of water vapor contained in the air passing through the evaporator 364 may be reduced.
Using the condensation occurring around the evaporator 364, the drying machine 300 may reduce the amount of water vapor contained in the air inside the drum 330 and dry the object to be dried.
The evaporator 364 may be disposed more upstream than the condenser 362 on the basis of the flow of air due to the fan 340. The air circulating due to the fan 340 may be dried (water vapor may be condensed) by the evaporator 364 while the air passes through the evaporator 364, and then the air may be heated by the condenser 362 while passing through the condenser 362.
The heater 355 may assist the condenser 362 in heating the air. For example, before the condenser 362 of the heat pump 360 sufficiently heats the air in the duct 350, the heater 355 may assist the condenser 362 in heating the air in the duct 350.
The temperature inside the drum 330 may more rapidly rise due to the heater 355 assisting the condenser 362, and the drying machine 300 may more rapidly dry the object to be dried.
The heater 355 may be disposed more downstream than the condenser 362 on the basis of the flow of air due to the fan 340. The heater 355 may be implemented through a heating coil. However, the heater 355 is not limited thereto and may be implemented through various other known devices.

Hereinafter, the operations of the washing machine 100 and the drying machine 300 will be described. The operation of the washing machine 100 may be performed under the control of the controller 190 and/or the processor 191, and the operation of the drying machine 300 may be performed under the control of the controller 390 and/or the processor 391.
FIGS. 15 a and 15 b illustrate a mode switching method of a washing machine according to an embodiment.
Referring to FIGS. 15 a and 15 b , a mode switching method 1000 of the washing machine 100 is described.
The washing machine 100 may be turned on (1005).
The washing machine 100 may be placed in the “standby state” in which the plug is inserted into the power socket and the user's power-on command is not input.
When the washer power button 211 of the control panel 110 is touched or pressed by the user, the washing machine 100 may be switched from the “standby state” to the ‘on state.’ In the ‘standby state,’ the power may be supplied to the controller 190 and the control panel 110. The power may be supplied to the first touch switch 211 a of the washer power button 211. The first touch switch 211 a may detect a user touch for powering on the washing machine 100 and provide the electrical signal according to the detection of the user touch to the controller 190. The controller 190 may supply power to all of the components included in the washing machine 100 in response to the user touch for power on. In other words, the washing machine 100 may be switched from the “standby state” to the “on state,” and in the “on state,” the power may be supplied to all of the components included in the washing machine 100.
The washing machine 100 may determine whether the washing machine 100 is connected to the drying machine 300 (1010).
The controller 190 may identify whether it is possible to communicate with the drying machine 300 through the communication device 180.
For example, the controller 190 may identify whether the communication line 181 a or the wireless dongle 182 a is inserted into the communication interface 183. When the communication line 181 a or the wireless dongle 182 a is not inserted into the communication interface 183, the controller 190 may identify that it is not connected to the drying machine 300.
When the communication line 181 a or the wireless dongle 182 a is inserted into the communication interface 183, the controller 190 may transmit a request message and identify whether a response message has been received in response to the request message. When the response message is not received, the controller 190 may identify that it is not connected to the drying machine 300.
When the response message is received, the controller 190 may identify whether the drying machine 300 can communicate by wire or wirelessly with the drying machine 300.
Upon identifying that the controller 190 can communicate with the drying machine 300, the controller 190 may identify whether the communication line 181 a has been inserted into the communication interface 183 or the wireless dongle 182 a has been inserted. In other words, the controller 190 may identify whether the drying machine 300 can communicate by wire or wirelessly with the drying machine 300.
When the washing machine 100 determines that the washing machine 100 is connected to the drying machine 300 (YES in 1010), the washing machine 100 may obtain information of the drying machine 300 from the drying machine 300 (1015).
When it is identified that communication with the drying machine 300 is possible, the controller 190 may request the drying operation information and/or the drying setting information of the drying machine 300 through the communication device 180, and receive the drying operation information and/or the drying setting information of the drying machine 300 through the communication device 180. For example, the controller 190 may determine whether the drying machine 300 is in the “on state,” and when it is in the “on state,” the controller 190 may determine whether the drying machine 300 is in the drying operation. When the drying machine 300 is in the drying operation, the controller 190 may receive the time remaining until the drying operation is completed through the communication device 180.
Based on the information received from the drying machine 300, the controller 190 may determine whether the drying machine 300 is in the “on state,” and when it is in the “on state,” the controller 190 may determine whether the drying machine 300 is in the drying operation. When the drying machine 300 is in the drying operation, the controller 190 may identify the time remaining until the drying operation is completed.
As such, the washing machine 100 may identify whether the washing machine 100 is connected to the drying machine 300 after being powered on, and receive the operation information and/or the setting information of the drying machine 300 from the drying machine 300.
However, the disclosure is not limited thereto, and the washing machine 100 may supply power to the communication device 180 at a predetermined cycle during the ‘standby state,’ identify whether the washing machine 100 is connected to the drying machine 300 through the communication device 180, and receive the operation information and/or the setting information of the drying machine 300 from the drying machine 300. In addition, the washing machine 100 may identify whether the washing machine 100 is connected to the drying machine 300 through the communication device 180 at the predetermined cycle even during the “on state” and receive the operation information and/or the setting information of the drying machine 300 from the drying machine 300.
After determining that the drying machine 300 is not connected (NO in 1010) or receiving information of the drying machine 300, the washing machine 100 may operate in the washer control mode (1020).
Regardless of whether the communication of the drying machine 300 is possible, the washing machine 100 may operate in the washer control mode after being turned on. In other words, the washer control mode may be a default setting of the operating mode of the washing machine 100.
After the washing machine 100 is turned on, until the user input for switching the operation mode is obtained, the controller 190 may operate in the washer control mode. In the washer control mode, the controller 190 may display information of the washing machine 100 and obtain the user input to the washing machine 100. Particularly, in the washer control mode, the controller 190 may display the washing operation information and/or washing setting information and obtain the user input for controlling the washing operation and/or the washing setting.
The controller 190 may control the control panel 110 so that the washer control button 222 emits light. The controller 190 may control the control panel 110 to display the washing course on the course display 251. In addition, the controller 190 may control the control panel 110 to display the ‘washing temperature,’ ‘number of rinsing times,’ and ‘dehydrating strength’ on the first setting button 261, the second setting button 262, and the third setting button 263, respectively. In other words, the controller 190 may control the control panel 110 to display information related to the operation of the washing machine 100 on the display, and obtain inputs related to the operation of the washing machine 100 through input buttons.
Thereafter, the washing machine 100 may determine whether the washing operation is in progress (1025).
The controller 190 may store data indicating that the washing is not performed in the memory 192 before the washing machine 100 starts the washing operation. In addition, the controller 190 may store data indicating the washing operation in the memory 192 in response to a washing start command through the washing operation button 232.
The controller 190 may identify whether the washing machine 100 is operating or whether the washing machine 100 is not operating based on data stored in the memory 192. For example, the controller 190 may identify that the washing machine 100 is operating based on data stored in the memory 192 during the washing operation. In addition, the controller 190 may identify that the washing machine 100 is not in operation, based on data indicating that the washing is not performed in the memory 192.
When the washing is in operation (YES in 1025), the washing machine 100 may display the washing operation information (1030), and when the washing is not in operation (NO in 1025), the washing machine 100 may display the washing setting information (1035).
When the washing machine 100 is in operation, the controller 190 may display information about the washing operation of the washing machine 100 on the control panel 110. For example, the controller 190 may display the time remaining until the end of the washing operation on the course display 251.
In addition, when the washing machine 100 is not in operation, the controller 190 may display information about the washing setting of the washing machine 100 on the control panel 110. For example, the controller 190 may display the washing course on the course display 251, the washing temperature on the first setting display 271, the number of rinsing times on the second setting display 272, and the dehydrating strength on the third setting display 273.

The control panel 110 may be provided with the dryer control button 221 for obtaining the user input to activate the dryer control for controlling the drying machine 300. In order to switch the operation mode of the washing machine 100 to the dryer control mode that can control the drying machine 300 using the control panel 110 of the washing machine 100, the user may touch or press the dryer control button 221.
When the dryer control button 221 is touched or pressed, the controller 190 may determine that the user input for activating the dryer control is obtained.
When the user input for switching to the dryer control mode is not obtained (NO in 1040), the washing machine 100 may maintain the washer control mode. In addition, the washing machine 100 may display the washing operation information and/or the washing setting information and obtain the user input for controlling the washing operation and/or the washing setting.
When the user input for switching to the dryer control mode is obtained (YES in 1040), the washing machine 100 may determine whether the washing machine 100 is connected to the drying machine 300 (1045).
In response to the dryer control button 221 being touched, the controller 190 may determine whether it is possible to communicate with the drying machine 300 through the communication device 180. In other words, the controller 190 may identify whether it is possible to switch to the dryer control mode.
Operation 1045 may be the same as operation 1010.
When it is determined that the washing machine 100 is not connected to the drying machine 300 (NO in 1045), the washing machine 100 may maintain the washer control mode.
When the washing machine 100 determines that the washing machine 100 is connected to the drying machine 300 (YES in 1045), the washing machine 100 may obtain information of the drying machine 300 from the drying machine 300 (1055).
Operation 1055 may be the same as operation 1015.
As described above, when the washing machine 100 obtains the user input for switching to the dryer control mode, the washing machine 100 may identify whether the washing machine 100 is connected to the drying machine 300 and receive the operation information and/or the setting information of the drying machine 300 from the drying machine 300.

The controller 190 may obtain the user input for starting the drying operation or the user input for pausing the drying operation from the user through the drying operation button 231, regardless of the control mode of the washing machine 100. In other words, the controller 190 may obtain the user input for starting the drying operation or the user input for pausing the drying operation through the drying operation button 231 in the dryer control mode, as well as the user input for starting the drying operation or the user input for pausing the drying operation through the drying operation button 231 in the washer control mode while operation information of the washing machine is displayed on the display 251.
When the washing machine 100 determines that it has obtained the user input for starting or pausing drying (YES in 1230), the washing machine 100 may transmit a control command to the drying machine 300 to start the drying operation or to pause the drying operation (1235).
In response to the drying operation button 231 being touched or depressed, the controller 190 may control the communication device 180 so that the drying machine 300 transmits the control command for starting the drying operation to the drying machine 300. In addition, the controller 190 may control the communication device 180 to transmit the control command for starting the drying operation to the drying machine 300, along with information about the drying course and/or the drying settings.
The controller 190 may determine whether to transmit the control command for starting the drying operation to the drying machine 300, depending on whether the wired or wireless communication with the drying machine 300 is performed. For example, when communicating with the washing machine 100 and the drying machine 300 by wire, the controller 190 may transmit the control command for starting the drying operation to the drying machine 300.
On the other hand, when the washing machine 100 communicates wirelessly with the drying machine 300, the controller 190 may not transmit the control command for starting the drying operation to the drying machine 300. When the washing machine 100 communicates wirelessly with the drying machine 300, the washing machine 100 may be located away from the drying machine 300. Therefore, the user of the washing machine 100 may operate the drying machine 300 without checking the drying machine 300. For example, even if a pet or the like is contained inside the drying machine 300, the user may operate the drying machine 300 without checking it. To prevent this, when the washing machine 100 communicates wirelessly with the drying machine 300, it may be prevented (or prohibited) that the controller 190 of the washing machine 100 transmits the drying operation command for rotating the drum 330 of the drying machine 300 to the drying machine 300.
As such, the controller 190 may preferably control the wired communication module 181 so that the drying machine 300 transmits the control command for starting the drying operation to the drying machine 300.
The controller 390 of the drying machine 300 may receive the control command for starting the drying operation through the communication device 380. In response to the control command for starting the drying operation, the controller 390 may control the components included in the drying machine 300 to perform the drying operation. The controller 390 may identify whether the door 302 is closed depending on an output signal of the door switch 303. When it is identified that the door 302 is closed, the controller 390 may control the door lock 304 to lock the door 302. When it is identified that the door 302 is locked, the controller 390 may control the drum motor 335 to rotate the drum 330, control the fan motor 345 to rotate the fan 340, and control the heater 355 to heat the inside of the duct 350.
In addition, in response to the drying operation button 231 being touched or pressed during the drying operation of the drying machine 300, the controller 190 of the washing machine 100 may control the communication device 180 so that the drying machine 300 transmits the control command for pausing the drying operation to the drying machine 300.

Returning to operation 1325, upon obtaining the user input for switching to the dryer control mode (YES in 1325), the washing machine 100 may obtain information of the drying machine 300 from the drying machine 300 (1355). The washing machine 100 may operate in the dryer control mode (1360), display the drying setting information or the drying operation information (1365), and determine whether the user input for switching to the washer control mode is obtained (1370).
Operation 1355, operation 1360, operation 1365, and operation 1370 may be the same as operation 1155, operation 1160, operation 1165, and operation 1170 illustrated in FIG. 16 .
When the user input for switching to the washer control mode is obtained (YES in 1370), the washing machine 100 may operate in the washer control mode (1315).
When it is determined that the washing machine 100 does not obtain the user input for switching to the washer control mode (NO in 1370), the washing machine 100 may determine whether the user input for the remote control is obtained in the dryer control mode (1375).
Operation 1375 may be the same as operation 1330.
When it is determined that the washing machine 100 obtains the user input for activating the remote control (YES in 1375), the washing machine 100 may determine whether the door 302 of the drying machine 300 is locked (1380). When it is determined that the door 302 of the drying machine 300 is locked (YES in 1380), the washing machine 100 may activate the remote control of the drying machine 300 (1385).
Operation 1380 and operation 1385 may be the same as operation 1345 and operation 1350.
When it is determined that the door 302 of the drying machine 300 is not locked (NO in 1380), the washing machine 100 may determine whether the door 102 of the washing machine 100 is locked (1390). When it is determined that the door 102 of the washing machine 100 is locked (YES in 1390), the washing machine 100 may activate the remote control of the washing machine 100 (1395).
Operation 1390 and operation 1395 may be the same as operation 1335 and operation 1340.
When it is determined that the door 102 of the washing machine 100 is not locked (NO in 1390), the washing machine 100 may continue to obtain the user input in the dryer control mode.

However, when it is determined that the door 102 of the washing machine 100 is not locked, the washing machine 100 may not allow the remote control. When it is determined that the door 302 of the drying machine 300 is not locked, the washing machine 100 may not transmit the control command for allowing the wireless remote control of the drying machine 300 to the drying machine 300.
When the remote control is permitted, the washing machine 100 (or drying machine) may wirelessly communicate with the external device and may receive the control command from the external device. When the washing machine 100 (or drying machine) communicates wirelessly, the washing machine 100 (or drying machine) may be located away from the external device. Therefore, the user of the external device may operate the washing machine 100 (or drying machine) without confirming the state of the washing machine 100 (or drying machine). For example, even if a pet or the like is contained inside the washing machine 100 (or drying machine), the user may operate the washing machine 100 (or drying machine) without confirming the pet. To prevent this, the washing machine 100 (or drying machine) may allow the remote control when the door 102 is locked (i.e., after the operation of the washing machine is started). The remote control of the drying machine 300 may be activated in the same way as the washing machine 100.
FIG. 24 is a view illustrating a power-off method of a washing machine and a drying machine according to an embodiment. FIG. 25 is a view illustrating power-off of a drying machine by a washing machine according to an embodiment.
Referring to FIGS. 24 and 25 , a power-off method 1400 of the washing machine 100 is described.
The washing machine 100 may be turned on (1405), obtain information of the drying machine 300 from the drying machine 300 (1410), operate in the washer control mode (1415), display the washing setting information or the washing operation information (1420), and determine whether the user input for switching to the dryer control mode is obtained (1425).
Operation 1405, operation 1410, operation 1415, operation 1420, and operation 1425 may be the same as operation 1105, operation 1110, operation 1115, operation 1120, and operation 1125 illustrated in FIG. 16 .
When it is determined that the washing machine 100 does not obtain the user input for switching to the dryer control mode (NO in 1425), the washing machine 100 may determine whether the user input for power-off in the washer control mode (user input for switching to the standby state) is obtained (1430).
The control panel 110 may be provided with the washer power button 211 for obtaining the user input to power-on the washing machine 100 or power-off the washing machine 100.
For example, as illustrated in FIG. 24 , the user may input the user input for switching the washing machine 100 in the “on state” to the “standby state” through the washer power button 211 in the washer control mode. In response to the washer power button 211 being touched or pressed, the controller 190 may switch the washing machine 100 from the “standby state” to the “on state” or from the “on state” to the ‘standby state.’
When it is determined that the user input for power-off (user input for switching to the standby state) is not obtained (NO in 1430), the washing machine 100 may wait for the user input in the washer control mode.
When it is determined that the user input for power-off is obtained (YES in 1430), the washing machine 100 is powered-off (turns washing machine to the standby state) (1435).
The controller 190 may switch the washing machine 100 in the “on state” to the ‘standby state.’
In the ‘standby state,’ limited power may be supplied to the components of the washing machine 100. For example, the power may be supplied to all of the components of the washing machine 100 in the “on state,” but in the ‘standby state,’ the power may be limitedly supplied to the control panel 110, the communication device 180, and the controller 190.
As such, the controller 190 may switch the washing machine 100 in the “on state” to the “standby state” in response to obtaining the user input for power-off in the washer control mode.
Returning to operation 1425, upon obtaining the user input for switching to the dryer control mode (YES in 1425), the washing machine 100 may obtain information of the drying machine 300 from the drying machine 300 (1455). The washing machine 100 may operate in the dryer control mode (1460), display the drying setting information or the drying operation information (1465), and determine whether the user input for switching to the washer control mode is obtained (1470).
Operation 1455, operation 1460, operation 1465, and operation 1470 may be the same as operation 1155, operation 1160, operation 1165, and operation 1170 illustrated in FIG. 16 .
When the user input for switching to the washer control mode is obtained (YES in 1470), the washing machine 100 may operate in the washer control mode (1415).
When it is determined that the washing machine 100 does not obtain the user input for switching to the washer control mode (NO in 1470), the washing machine 100 may determine whether the user input for power-off in the dryer control mode is obtained (1475). When it is determined that the washing machine 100 has obtained the user input for power-off (YES in 1475), the drying machine 300 may be powered-off (turned the washing machine to the standby state) (1480).
In response to the washer power button 211 being touched or pressed in the dryer control mode, the controller 190 may transmit the control command for switching the power state of the drying machine 300 to the drying machine 300 through the communication device 180.
For example, the controller 190 may identify the power state of the drying machine 300 (e.g., in the standby state or in the on state) based on information received from the drying machine 300. Upon identifying that the drying machine 300 is in the ‘standby state,’ the controller 190 may transmit the control command for switching the drying machine 300 that is in the “standby state” to the “on state” to the drying machine 300. Upon identifying that the drying machine 300 is in the “on state,” the controller 190 may transmit the control command for switching the drying machine 300 that is in the “on state” to the “standby state” to the drying machine 300.
The controller 390 of the drying machine 300 may receive the control command for switching the power state from the washing machine 100 and switch the power state of the drying machine 300 in response to the received control command.
In the above, it has been described that the washing machine 100 changes the power state of the drying machine 300 in response to the washer power button 211 being touched or pressed in the dryer control mode, but is not limited thereto. The washing machine 100 may change the power state of the washing machine 100 itself in response to the washer power button 211 being touched or pressed in the dryer control mode. Particularly, the washing machine 100 may be switched from the “on state” to the “standby state” in response to the washer power button 211 being touched or pressed in the dryer control mode.
As described above, the washing machine 100 may switch the power state from the “on state” to the “standby state” in response to the user input for power-off in the washer control mode. The washing machine 100 may transmit the control command for switching the power state of the drying machine 300 to the drying machine 300 in response to the user input for power-off in the dryer control mode. Thereby, the user may power-on or power-off the drying machine 300 using the control panel 110 of the washing machine 100.
As described above, the washing machine may include the control panel; the drum; the drum motor; the communication device configured to exchange data with the drying machine; and the controller electrically connected to the control panel, the drum motor, and the communication device. The controller may operate in one of a first mode and a second mode depending on a first user input through the control panel, control the communication device to transmit the control command for controlling the drying machine to the drying machine in response to a second user input through the control panel in the first mode, and control the drum motor to rotate the drum in response to a third user input through the control panel in the second mode.
Thereby, the user may not only control the operation of the washing machine using the control panel of the washing machine, but also control the operation of the drying machine in communication with the washing machine. In other words, the user may be provided with the first user interface for controlling the washing machine and the second user interface for controlling the drying machine through one control panel.
The control panel may include a first control switch and a second control switch. The controller may switch to the first mode in response to the user input through the first control switch in the second mode, and may switch to the second mode in response to the user input through the second control switch in the first mode.
The control panel may include at least one input switch. The controller may obtain the second user input for controlling the drying machine through the at the least one input switch in the first mode, and may obtain the third user input for controlling the drying machine through the at the least one input switch in the second mode.
Thereby, a size of a menu (or button) for controlling the washing machine or the drying machine is not reduced, and the user's operation error due to miniaturization of the menu (or button) may be prevented or reduced.
The control panel includes a first action switch and a second action switch. In both the first mode and the second mode, the controller may control the communication device to transmit the control command for starting the drying operation to the drying machine in response to the user input through the first action switch, and may control the drum motor to rotate the drum for washing in response to the user input through the second action switch.
Thereby, the user may stop the washing machine or the drying machine with one button in an urgent situation, and may further quickly stop the operation of the drying machine or the washing machine in the urgent situation.
The communication device may exchange data with the drying machine, either by wire or wirelessly. When the communication device exchanges data with the drying machine by wire, the controller may control the communication device to transmit the control command for starting the drying operation of the drying machine. When the communication device exchanges data with the drying machine wirelessly, the controller may not transmit the control command for starting the drying operation of the drying machine.
Thereby, the user of the washing machine may be prevented from operating the drying machine without checking the drying machine. In other words, a safety accident caused by the drying machine may be prevented or reduced.
The control panel may include at least one input switch. In both the first mode and the second mode, the controller may control the communication device to transmit the control command for activating the remote control of the drying machine in response to the user input through the at least one input switch, and may activate the remote control of the washing machine. The washing machine may further include a cabinet that accommodates the drum and has an opening formed on a front surface and a door that can close the opening. The controller may determine whether the door is closed in response to the user input through the at least one input switch, activate the remote control of the washing machine in response to determining that the door is closed, and deactivate the remote control of the washing machine in response to determining that the door is not closed.
Thereby, the user of the external device may be prevented from operating the washing machine (or drying machine) without checking the condition of the washing machine (or drying machine). In other words, a safety accident of the washing machine (or drying machine) by remote control may be prevented or reduced.
In response to at least one of the user input for power-on of the washing machine and the user input for controlling the drying machine, the controller may control the communication device to identify when it is communicable with the drying machine and to receive information from the drying machine. The controller may control the communication device to identify whether it is possible to communicate with the drying machine and receive information from the drying machine at predetermined times.
Thereby, the washing machine may monitor the operation of the drying machine, and provide information about the operation of the drying machine to the user through the control panel.
According to an aspect of the disclosure, there is provided the washing machine capable of controlling the drying machine using the control panel of the washing machine, and the method of controlling the washing machine. Thereby, even if the drying machine is installed on the washing machine, the user may operate the drying machine without inconvenience.
According to another aspect of an embodiment, there is provided the washing machine capable of integrating the menu (or button) capable of controlling the washing machine and the menu (or button) capable of controlling the drying machine, and the method of controlling the washing machine. Thereby, a size of the menu (or button) for controlling the washing machine or the drying machine is not reduced, and the user's operation error due to miniaturization of the menu (or button) may be prevented or reduced.
