The evaporator 364 may evaporate the liquid refrigerant expanded in the expander 363. As a result, the evaporator 364 can return the low-temperature, low-pressure individual refrigerant to the compressor 361.

The evaporator 364 can absorb heat from the surroundings through an evaporation process that changes low-pressure liquid refrigerant into gaseous refrigerant. The evaporator 364 may be provided on the duct 350 and may cool the air passing through the evaporator 364 during the evaporation process.

The surrounding air is cooled by the evaporator 364, and when the temperature of the surrounding air falls below the dew point, the air surrounding the evaporator 364 may condense. As condensation occurs 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 decrease.

Using condensation around the evaporator 364, the dryer 300 can reduce the amount of water vapor contained in the air inside the drum 330 and also dry the dried material.

The evaporator 364 may be located upstream of the condenser 362 based on the air flow by the fan 340. The air circulating by the fan 340 is dried (water vapor is condensed) by the evaporator 364, and can then be heated by the condenser 362 while passing through the condenser 362. there is.

The heater 355 assists the condenser 362 and can heat the air. For example, the heater 355 may heat the air in the duct 350 by assisting the condenser 362 before the condenser 362 of the heat pump 360 sufficiently heats the air in the duct 350.

The temperature inside the drum 330 can rise more quickly by the heater 355 that assists the condenser 362, and the dryer 300 can dry the dried material more quickly.

The heater 355 may be located downstream of the condenser 362 based on the air flow by the fan 340. The heater 355 may be implemented through a heating coil. However, the heater 355 is not limited to this and can be implemented using various already known elements.

Figure 15 shows a mode switching operation of a washing machine according to one embodiment.

Together with FIG. 15, a mode switching method 1000 of the washing machine 100 is explained.

The washing machine 100 is turned on (1005).

The washing machine 100 may be placed in a “standby state” when its plug is inserted into the power socket and no power-on command from the user is input.

When the washing machine power button 211 on the control panel 110 is touched or pressed by the user, the washing machine 100 can be switched from the 'standby state' to the 'on state'. In the “standby state,” power may be supplied to the control unit 190 and the control panel 110. Power may be supplied to the first touch switch 211a of the washing machine power button 211, and the first touch switch 211a may detect a user touch for powering on the washing machine 100, and the first touch switch 211a may detect a user touch for powering on the washing machine 100. An electrical signal according to detection may be provided to the control unit 190. The control unit 190 may supply power to all components included in the washing machine 100 in response to a user touch to turn on the power. In other words, the washing machine 100 switches from the “standby state” to the “on state,” and power can be supplied to all components included in the washing machine 100 in the “on state.”

The washing machine 100 determines whether it is connected to the dryer 300 (1010).

The control unit 190 can identify whether it can communicate with the dryer 300 through the communication unit 180.

For example, the control unit 190 may identify whether the communication line 181a or the wireless dongle 182a is inserted into the communication interface 183. It can be identified that the communication line 181a or the wireless dongle 182a is not inserted into the communication interface 183, and the control unit 190 is not connected to the dryer 300.

If the communication line 181a or the wireless dongle 182a is inserted into the communication interface 183, the control unit 190 can transmit a request message and identify whether a response message has been received in response to the request message. If a response message is not received, the control unit 190 can identify that it is not connected to the dryer 300.

When the response message is received, the control unit 190 can identify that it is connected to the dryer 300 and can communicate with the dryer 300.

Once it is identified that communication with the dryer 300 is possible, the control unit 190 can identify whether the communication line 181a or the wireless dongle 182a is inserted into the communication interface 183. In other words, the control unit 190 can identify whether it can communicate with the dryer 300 by wire or wirelessly.

When the washing machine 100 determines that it is connected to the dryer 300 (yes in 1010), it obtains information about the dryer 300 from the dryer 300 (1015).

If it is identified that communication with the dryer 300 is possible, the control unit 190 may request drying operation information and/or drying setting information of the dryer 300 through the communication unit 180, and the dryer ( 300) drying operation information and/or drying setting information may be received. For example, the control unit 190 determines whether the dryer 300 is in the “on state”, if the dryer 300 is in the “on state”, whether the dryer 300 is in a drying operation, and if the dryer 300 is in a drying operation, the remaining time until the drying operation is completed. The time can be received through the communication unit 180.

Based on the information received from the dryer 300, the control unit 190 determines whether the dryer 300 is in the “on state,” and if the dryer 300 is in the “on state,” whether the dryer 300 is in a drying operation or whether the dryer 300 is in a drying operation. If it is in progress, you can identify the time remaining until the drying operation is completed.

In this way, the washing machine 100 can identify whether it is connected to the dryer 300 after being turned on, and receive operation information and/or setting information of the dryer 300 from the dryer 300.

However, it is not limited to this, and the washing machine 100 supplies power to the communication unit 180 at a predetermined cycle during the “standby state”, identifies whether it is connected to the dryer 300 through the communication unit 180, and Operation information and/or setting information of the dryer 300 may be received from (300). In addition, even during the “on state,” the washing machine 100 identifies whether it is connected to the dryer 300 through the communication unit 180 at a predetermined cycle and receives operation information and/or settings of the dryer 300 from the dryer 300. Information can be received.

After it is determined that it is not connected to the dryer 300 (No in 1010) or after receiving information from the dryer 300, the washing machine 100 operates in the washing machine control mode (1020).

Regardless of whether communication is possible with the dryer 300, the washing machine 100 can operate in the washing machine control mode after being turned on. In other words, the washing machine control mode is the default setting for the operation mode of the washing machine 100.

After the washing machine 100 is turned on and before obtaining a user input for switching the operation mode, the control unit 190 may operate in the washing machine control mode. The control unit 190 may display information on the washing machine 100 and obtain user input for the washing machine 100 in the washing machine control mode.

When the control unit 190 identifies that the dryer 300 is in a “standby state,” it can transmit a control command to the dryer 300 to switch the dryer 300 from the “standby state” to the “on state.” If it is identified that the dryer 300 is in the “on state,” a control command for switching the dryer 300 in the “on state” to the “standby state” may be transmitted to the dryer 300.

The control unit 390 of the dryer 300 may receive a control command for switching the power state from the washing machine 100 and change the power state of the dryer 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 dryer 300 in response to the washing machine power button 211 being touched or pressed in the dryer control mode, but the washing machine is not limited to this. 100 may change the power state of the washing machine 100 itself in response to the washing machine power button 211 being touched or pressed in the dryer control mode. Specifically, the washing machine 100 may switch from the “on state” to the “standby state” in response to the washing machine power button 211 being touched or pressed in the dryer control mode.

As described above, the washing machine 100 can change its power state from “on state” to “standby state” in response to a user input for power-off in the washing machine control mode, and in the dryer control mode. A control command for switching the power state of the dryer 300 may be transmitted to the dryer 300 in response to a user input for power-off. Accordingly, the user can turn the dryer 300 on or off using the control panel 110 of the washing machine 100.
