The control unit (80) may cut off the power supplied to the drying heater (120) based on the electrical signal received from the first temperature sensor (171), the second temperature sensor (172), and the third temperature sensor (173).

[0229] The humidity sensor (180) can detect the humidity of the air discharged from the tub (20) and transmit an electrical signal corresponding to the humidity of the air discharged from the tub (20) to the control unit (80). The control unit (80) can determine the humidity value of the air discharged from the tub (20) based on the electrical signal received from the humidity sensor (180). For example, the humidity sensor (180) may be provided on the side closer to the discharge guide (145) than to the duct guide (144) in the discharge path (146).

[0230] For example, an electrical signal corresponding to the humidity of the air discharged from the tub (20) may be a voltage, and the control unit (80) may determine the humidity value of the air discharged from the tub (20) based on the magnitude of the voltage. Since the humidity value of the air discharged from the tub (20) corresponds to the magnitude of the voltage, the humidity value detected by the humidity sensor (180) in the present invention may mean the electrical signal output from the humidity sensor (180) and / or the humidity value determined by the control unit (80) based on the electrical signal output from the humidity sensor (180).

[0231] The communication interface (89) may include various communication circuits for performing wired communication and / or wireless communication with an external device (e.g., a server, a user device, and / or other home appliance). The user device may include various electronic devices such as a smartphone, a notebook, a laptop, a smart watch, a stationary tablet, and a speaker. User input may be obtained through the user device as well as through the control panel (15).

[0232] The communication interface (89) may include at least one of a short-range communication circuit and a long-range communication circuit. The communication interface (89) may transmit data to an external device or receive data from an external device. For example, the communication interface (89) may support cellular communication, wireless local area network, home radio frequency (RF), infrared communication, ultra-wide band (UWB) communication, Wi-Fi, Wi-Fi Direct, Bluetooth, AD-HOC, and / or Zigbee. The communication technologies supported by the communication interface (89) are not limited to those exemplified.

[0233] The communication interface (89) may also communicate with an external device through an access point (AP). The access point can connect the local network (LAN) to which the clothing processing device (1) is connected to a wide area network (WAN) to which the server is connected. The clothing processing device (1) can be connected to the server through the wide area network (WAN).

[0234] FIG. 21 is a flowchart of a control method for a clothing processing device according to one embodiment of the present disclosure.

[0235] Referring to FIG. 21, a clothing processing device (1) according to one embodiment can perform fire prevention control to prevent a fire caused by overheating of the drying heater (120). The clothing processing device (1) can start the operation of the drying heater (120) based on the fact that the conditions for starting the drying process are satisfied (1000).

[0236] Based on the start of operation of the drying heater (120), the temperature of the hot air supply device (110) may rise. The first temperature sensor (171) may detect whether the temperature value at the first position of the hot air supply device (110) has reached a predetermined first temperature value (1100). For example, the temperature value at the first position of the hot air supply device (110) reaching the first temperature value may include the case where the supply fan (130) is inoperable.

[0237] Based on the detection of a first temperature value by the first temperature sensor (171), the power supplied to the drying heater (120) may be temporarily cut off (1200). For example, the first temperature sensor (171) may temporarily cut off the power supplied to the drying heater (120) based on the fact that the temperature value at the first position of the hot air supply device (110) has reached the first temperature value. For example, the control unit (80) may temporarily cut off the power supplied to the drying heater (120) in response to the detection by the first temperature sensor (171) that the temperature value at the first position of the hot air supply device (110) has reached the first temperature value.

[0238] Based on the fact that the first temperature value is not detected by the first temperature sensor (171), the third temperature sensor (173) can detect whether the temperature value at the third position of the hot air supply device (110) has reached a predetermined first temperature value (1300). For example, the fact that the first temperature value is not detected by the first temperature sensor (171) may include the case where the first temperature sensor (171) is inoperable.

[0239] Based on the detection of a first temperature value by the third temperature sensor (173), the power supplied to the drying heater (120) may be temporarily cut off (1200). For example, the third temperature sensor (173) may temporarily cut off the power supplied to the drying heater (120) based on the fact that the temperature value at the third position of the hot air supply device (110) has reached the first temperature value. For example, the control unit (80) may temporarily cut off the power supplied to the drying heater (120) in response to the detection by the third temperature sensor (173) that the temperature value at the third position of the hot air supply device (110) has reached the first temperature value.

[0240] Based on the fact that the first temperature value is not detected by the third temperature sensor (173), the first temperature sensor (171) can detect whether the temperature value at the first position of the hot air supply device (110) has reached the first temperature value (1100).

[0241] When the power to the drying heater (120) is temporarily cut off, the temperature value of the hot air supply device (110) may rise due to latent heat. After the power to the drying heater (120) is temporarily cut off, the second temperature sensor (172) can detect whether the temperature value at the second position of the hot air supply device (110) has reached a predetermined second temperature value (1400). The second second temperature value may be higher than the first temperature value.

[0242] Based on the detection of a second temperature value by the second temperature sensor (172), the power supplied to the drying heater (120) may be permanently cut off (1500). For example, the second temperature sensor (172) may permanently cut off the power supplied to the drying heater (120) based on the fact that the temperature value at the second position of the hot air supply device (110) has reached the second temperature value. For example, the control unit (80) may permanently cut off the power supplied to the drying heater (120) in response to the detection by the second temperature sensor (172) that the temperature value at the second position of the hot air supply device (110) has reached the second temperature value. Based on the permanent cut-off of the power supplied to the drying heater (120), fire prevention control may be terminated.

[0243] For example, based on the fact that the second temperature value is not detected by the second temperature sensor (172), the control unit (80) can determine whether a predetermined time has elapsed (1600). Based on the fact that the predetermined time has not elapsed, the second temperature sensor (172) can detect whether the temperature value at the second position of the hot air supply device (110) has reached the second temperature value (1400). Based on the fact that the predetermined time has elapsed, the control unit (80) can restore the power supplied to the drying heater (120).

[0244] For example, based on the fact that the second temperature value is not detected by the second temperature sensor (172), the first temperature sensor (171) and / or the third temperature sensor (173) may be configured to automatically restore power supplied to the drying heater (120) after a predetermined time has elapsed.

[0245] Based on restoring power supplied to the drying heater (120), fire prevention control can be terminated.
