[0182] The temperature sensor (86) can detect the temperature of the humid air and transmit an electrical signal corresponding to the temperature of the humid air to the control unit (80).

The control unit (80) can determine the temperature of the air discharged from the tub (20) based on the electrical signal transmitted from the temperature sensor (86). The temperature sensor (86) may be located on the discharge path of the discharge device (140).

[0183] According to one embodiment, the clothing processing device (1) may include a plurality of temperature sensors (86a, 86b). For example, the plurality of temperature sensors (86a, 86b) may be located on the same cross-section of the discharge channel (146).

[0192] The control unit (80) can control the driving device (135) so that the drum (30) rotates at a preset rotational speed based on the fact that the temperature obtained by any one of the plurality of temperature sensors (86) is higher than or equal to a preset target temperature, and can control the water supply device (40) so that water is supplied into the drum (30).

[0193] At this time, the preset rotation speed may be slower than the rotation speed of the drum (30) when the dehydration process is performed.

[0194] The control unit (80) can stop the operation of the hot air supply device (110) before controlling the driving device (135) and the water supply device (40) based on the fact that the temperature obtained by any one of the plurality of temperature sensors (86) is higher than or equal to a preset target temperature.

[0195] The control unit (80) can control the water supply device (40) so that the water supply into the drum (30) is stopped based on the elapsed time of a preset reference time.

[0196] The control unit (80) can control the water supply device (40) to stop the supply of water into the drum (30) based on the fact that water has been supplied up to a critical water level in the drum (30).

[0197] The control unit (80) controls the output interface (15b) to output a guide interface regarding the end of the drying process based on the fact that one of the plurality of temperature sensors (86) is identified as abnormal during the drying process, and can determine whether the temperature obtained by one of the plurality of temperature sensors (86) is above a preset target temperature based on the fact that the plurality of temperature sensors (86) are identified as normal during the drying process.

[0198] The control unit (80) identifies that the multiple temperature sensors (86) are normal based on the difference in temperature obtained from the multiple temperature sensors (86) being less than a preset threshold value, and determines whether the difference in temperature obtained from the multiple temperature sensors (86) is greater than or equal to a preset threshold value after a first unit time has elapsed.

[0199] The control unit (80) can identify that the plurality of temperature sensors (86) are normal based on the difference in temperature obtained from the plurality of temperature sensors (86) after the first unit time has elapsed being less than a preset threshold value, and identify that at least one of the plurality of temperature sensors (86) is abnormal based on the difference in temperature obtained from the plurality of temperature sensors (86) after the first unit time has elapsed being greater than or equal to a preset threshold value.

[0200] The control unit (80) can determine whether the temperature obtained by one of the plurality of temperature sensors (86) is below the preset safety temperature after the second unit time has elapsed, based on the fact that the temperature obtained by one of the plurality of temperature sensors (86) is below the preset safety temperature.

[0202] The control unit (80) can control the driving device (135) to stop the rotation of the drum (30) based on the determination that the extinguishing of the drum (30) is complete, and control the drainage device (70) to drain the water supplied into the drum (30).

[0203] FIG. 12 is a flowchart of a control method for a clothing processing device according to one embodiment.

[0204] A control unit (80) of a clothing processing device (1) according to one embodiment can detect a malfunction of a temperature sensor (1100). That is, a control unit (80) according to one embodiment can identify whether the temperature sensor is abnormal. According to one embodiment, the clothing processing device (1) may include a plurality of temperature sensors (86a, 86b). A control unit (80) according to one embodiment can detect a malfunction of a temperature sensor based on the temperature difference of the plurality of temperature sensors (86a, 86b). A specific method for detecting a malfunction of a temperature sensor will be described in detail later with reference to FIG. 13.

[0205] A control unit (80) according to one embodiment can detect a malfunction of the temperature sensor during the drying process. However, according to various embodiments, the control unit (80) can detect a malfunction of the temperature sensor even outside of the drying process. For example, the control unit (80) can detect a malfunction of the temperature sensor even when the clothing processing device (1) is not operating according to a specific operation course and is simply powered on.

[0206] A control unit (80) according to one embodiment may provide a guide interface (1200) when a malfunction of a temperature sensor is detected, that is, when a plurality of temperature sensors are identified as abnormal (example of 1100). For example, when a malfunction of a temperature sensor is detected, the control unit (80) may provide a guide interface regarding the termination of the drying process, as it cannot detect even if a fire occurs in the drum (30) during the drying process.

[0207] In the present invention, the control unit (80) providing a guide interface may include the control unit (80) controlling an output interface (15b) to output a guide interface and / or the control unit (80) controlling a communication interface (89) to transmit a signal to an external device to output a guide interface.

[0208] The guide interface may include sensory information (e.g., visual information, auditory information, etc.) regarding a malfunction or abnormality of the temperature sensor.

[0209] The guide interface may include sensory information (e.g., visual information, auditory information, etc.) that guides the method for terminating the drying process.

[0210] In addition, the guide interface may include sensory information (e.g., visual information, auditory information, etc.) that induces the termination of the drying process.

[0211] On the other hand, the control unit (80) can determine whether a fire has occurred in the drum (1300) when no malfunction of the temperature sensor is detected, that is, when multiple temperature sensors are identified as normal (No of 1100). According to one embodiment, the control unit (80) can determine whether a fire has occurred based on whether the temperature obtained from any one of the multiple temperature sensors (86a, 86b) corresponds to or greater than the target temperature. According to one embodiment, the control unit (80) can perform a fire extinguishing operation as it determines that a fire has occurred (1400). The method of detecting a fire and performing a fire extinguishing operation will be described in detail later with reference to FIG. 14.

[0212] After performing the extinguishing process, the control unit (80) can determine whether the extinguishing is complete (1500). According to one embodiment, the control unit (80) can determine whether the extinguishing is complete based on whether the temperature obtained from any one of the plurality of temperature sensors (86a, 86b) corresponds to a preset safety temperature or higher. A method for determining whether the extinguishing is complete will be described in detail later with reference to FIG. 15.

[0213] FIG. 13 is a flowchart for explaining the process of identifying abnormalities in a temperature sensor in a control method of a clothing processing device according to one embodiment.

[0214] A clothing processing device (1) according to one embodiment may include a plurality of temperature sensors (86a, 86b). For example, the plurality of temperature sensors (86a, 86b) may include a first temperature sensor (86a) and a second temperature sensor (86b).

[0215] For example, the first temperature sensor (86a) and the second temperature sensor (86b) may be located on the same cross-section of the discharge channel (146). In other words, the first temperature sensor (86a) and the second temperature sensor (86b) may be located at positions spaced apart by the same distance from the starting point of the discharge channel (146).

[0216] According to one embodiment, the control unit (80) can obtain a first temperature from a first temperature sensor and a second temperature from a second temperature sensor (2001). Specifically, the control unit (80) can obtain a first temperature and a second temperature at the same time.

[0217] The control unit (80) can determine whether the difference between the first temperature and the second temperature is greater than or equal to a preset threshold value (2002). At this time, the first temperature and the second temperature may correspond to temperatures obtained from the first temperature sensor (86a) and the second temperature sensor (86b), respectively, at a predetermined same point in time. The preset threshold value may be preset as the temperature difference between the multiple temperature sensors (86a, 86b) that may occur when at least one of the multiple temperature sensors (86a, 86b) is abnormal. For example, the preset threshold value may correspond to 20℃.

[0218] The control unit (80) can identify that the plurality of temperature sensors (86a, 86b) are normal when the difference between the first temperature and the second temperature is less than a preset threshold (No in 2002) (2003).

[0219] On the other hand, the control unit (80) can determine whether the difference between the first temperature and the second temperature is greater than or equal to a preset threshold (No in 2002) and whether the difference between the temperatures obtained from the plurality of temperature sensors after the first unit time has elapsed is greater than or equal to a preset threshold (2004). At this time, the first unit time can be preset as an appropriate time during which a change in the difference between the first temperature and the second temperature may occur. For example, the first unit time may correspond to 3 seconds.

[0220] The control unit (80) can identify that the plurality of temperature sensors (86a, 86b) are normal (2003) if, after a first unit time has elapsed, the difference in temperature obtained from the plurality of temperature sensors is less than a preset threshold value (No in 2004).

[0221] On the other hand, the control unit (80) can identify that at least one of the plurality of temperature sensors (86a, 86b) is non-growth if the difference in temperature obtained from the plurality of temperature sensors after a first unit time has elapsed is greater than or equal to a preset threshold value (e.g., 2004).

[0222] The clothing processing device (1) according to the present disclosure can increase the reliability of the system by comparing the temperatures obtained through a plurality of temperature sensors (86a, 86b), thereby quickly detecting when one sensor malfunctions or outputs an abnormal value.

[0223] FIG. 14 is a flowchart illustrating the process of detecting a fire and performing a fire extinguishing operation in a control method of a clothing processing device according to one embodiment.

[0224] According to one embodiment, the control unit (80) can determine whether the temperature obtained by any one of the plurality of temperature sensors is above a preset target temperature based on the fact that the plurality of temperature sensors (86a, 86b) are identified as normal (3001). The one temperature sensor (86) that obtains the temperature to determine whether the temperature is above the target temperature among the plurality of temperature sensors (86a, 86b) may be either the first temperature sensor (86a) or the second temperature sensor (86b). For example, the one temperature sensor (86) that obtains the temperature to determine whether the temperature is above the target temperature among the plurality of temperature sensors (86a, 86b) may be preset. Additionally, the one temperature sensor that obtains the temperature to determine whether the temperature is above the target temperature among the temperature sensors (86a, 86b) may correspond to the temperature sensor that reaches the target temperature first among the plurality of temperature sensors (86a, 86b). At this time, the target temperature can be preset to an appropriate temperature of the heated air moving from the drum (30) to the exhaust path (146) as a fire occurs in the drum (30). For example, the target temperature may be 80°C.

[0225] According to various embodiments, the control unit (80) may determine whether the average temperature of the first temperature and the second temperature obtained from each of the plurality of temperature sensors (86a, 86b) is greater than or equal to a preset target temperature based on the fact that the plurality of temperature sensors (86a, 86b) are identified as normal.

[0226] The control unit (80) can determine that no fire has occurred in the drum (30) based on the fact that the temperature obtained by any one of the multiple temperature sensors (86a, 86b) is below a preset target temperature (No of 3001). After that, the control unit (80) can continuously detect a malfunction of the temperature sensor (86) (1100) and monitor whether a fire has occurred.

[0227] The control unit (80) can determine that a fire has occurred in the drum (30) (3002) based on the fact that a plurality of temperature sensors (86a, 86b) are identified as normal, and that the temperature obtained by any one of the plurality of temperature sensors is above a preset target temperature (e.g., 3001). Accordingly, the control unit (80) can perform a fire extinguishing operation.

[0228] A control unit (80) according to one embodiment can control a driving device (36) and / or a water supply device (40) to perform a fire extinguishing process (3003). Specifically, the control unit (80) can control the driving device (36) so that the drum (30) rotates at a preset rotational speed. When performing a fire extinguishing process, if the drum (30) rotates at a high speed, external air may be introduced due to changes in internal air pressure of the drum (30), which may be disadvantageous for fire extinguishing. Accordingly, the preset rotational speed can be preset at a speed at which the contact time or frequency of water between the object to be washed (also to be dried) being burned inside the drum (30) increases without external air being introduced into the drum (30). For example, the preset rotational speed can be preset at a speed slower than the rotational speed of the drum (30) when a dehydration process is performed. As another example, the preset rotational speed may be preset at a speed slower than the rotational speed of the drum (30) when the temperature obtained by any one of the multiple temperature sensors (86a, 86b) is below the preset target temperature. As another example, the preset rotational speed may be preset at a value of 45 rpm or more and 55 rpm or less.

[0229] Additionally, the control unit (80) can control the water supply device (40) so that water is supplied into the drum (30). According to one embodiment, rotation of the drum (30) at a preset rotational speed and supply of water into the drum (30) can be performed simultaneously or sequentially. For example, the control unit (80) can control the water supply device (40) and the drive device (36) to rotate the drum (30) at a preset rotational speed simultaneously with the supply of water into the drum (30). As another example, the control unit (80) can control the water supply device (40) and the drive device (36) to rotate the drum (30) at a preset rotational speed after a predetermined time has elapsed since starting to supply water into the drum (30).

[0230] According to various embodiments, the control unit (80) may control the water supply device (40) to regulate the flow rate of water supplied into the drum (30) based on the temperature obtained from any one of the plurality of temperature sensors (86a, 86b). For example, the control unit (80) may increase the flow rate of water supplied into the drum (30) as the temperature obtained from any one of the plurality of temperature sensors (86a, 86b) is higher than the target temperature.

[0231] According to various embodiments, the control unit (80) may control the water supply device (40) to regulate the flow rate of water supplied into the drum (30) based on the amount of material to be washed (or material to be dried) contained inside the drum (30). For example, the control unit (80) may increase the flow rate of water supplied into the drum (30) as the amount of material to be washed (or material to be dried) contained inside the drum (30) increases.

[0232] The control unit (80) can determine the amount of material to be washed (or material to be dried) contained inside the drum (30) before or during the drying process.

[0233] According to one embodiment, the control unit (80) may stop the operation of the hot air supply device (110) before controlling the driving device (36) and the water supply device (40) based on the fact that the temperature obtained by any one of the plurality of temperature sensors (86a, 86b) is above a preset target temperature. Accordingly, the control unit (80) may prevent the spread of fire by blocking the supply of heated air into the drum (30).

[0234] According to one embodiment, the control unit (80) can control the water supply device (40) to stop the water supply into the drum (30) based on the elapsed of a preset reference time. The preset reference time can be preset as an appropriate time required for extinguishing. For example, the preset reference time can be preset as a value between 9 minutes and 10 minutes.

[0235] According to one embodiment, the control unit (80) can control the water supply device (40) to stop the supply of water into the drum (30) based on the fact that water has been supplied up to a critical water level in the drum (30). At this time, the control unit (80) can detect whether the critical water level has been reached by various sensors (e.g., water level sensors) provided in the drum (30).

[0236] FIG. 15 is a flowchart for explaining the process of determining whether digestion is complete in a control method of a clothing processing device according to one embodiment.

[0237] A control unit (80) according to one embodiment can determine whether the extinguishing process is complete after performing the extinguishing process. A control unit (80) according to one embodiment can determine whether the extinguishing process is complete based on the temperature obtained from any one of a plurality of temperature sensors (86a, 86b).

That is, among the plurality of temperature sensors (86a, 86b), any one of the temperature sensors (86) that acquires the temperature to determine whether it is above the target temperature may be either the first temperature sensor (86a) or the second temperature sensor (86b). Additionally, among the temperature sensors (86a, 86b), any one of the temperature sensors that acquires the temperature to determine whether it is above the target temperature may be the temperature sensor that first reaches a preset safety temperature among the plurality of temperature sensors (86a, 86b).

At this time, the second unit time can be preset as an appropriate time during which a change in the difference between the first temperature and the second temperature can occur after the extinguishing process is performed. For example, the second unit time may correspond to 60 seconds.

[0242] The control unit (80) may determine that the fire extinguishing is incomplete if, after a second unit time has elapsed, the temperature obtained by any one of the plurality of temperature sensors (86a, 86b) exceeds a preset safety temperature.
