[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0041] The laundry treating apparatus is an apparatus for treating laundry such as washing, spinning, drying, etc., and can be a washing machine, a drying machine, a washer-dryer, etc. The laundry treating apparatus usually has a function of heating water to improve washing effect or dry laundry. The processing mode for the case of abnormally high temperature in the drum is usually to close the door lock and turn off all loads. However, this mode has limitations. When the temperature is abnormally high due to sticking of the heating tube relay contact, the processing mode cannot directly turn off the heating tube, so that the heating tube is still in an abnormal working state, which easily causes the heating tube to dry out.

[0042] Based on this, the present application provides a heating control method, device and laundry treating apparatus, which will be described below with reference to the drawings.

[0043] Please refer to Figure 1 shown, Figure 1 The first flowchart of the heating control method provided by the embodiment of the present application is shown. For example, the embodiment of the present application provides a heating control method, which includes the following steps.

[0044] Step S110: detecting the temperature in the drum of the laundry treating apparatus.

[0045] Step S120: when the temperature in the drum is greater than a first temperature threshold, controlling the door lock to be unlocked, so that the heating tube is disconnected from the live wire.

[0046] The laundry treating apparatus includes a heating tube and a door lock, and the heating tube is connected to the live wire through the door lock. Of course, the laundry treating apparatus is not limited to the above components, and can also include components such as a door body, a box body, a display panel, etc., which are not limited here.

[0047] Exemplarily, the heating pipe is used for heating the drum of the clothes treatment device, such as the heating pipe can be arranged at the bottom of the drum of the clothes treatment device to realize the heating of the drum, thereby adjusting the treatment of the clothes. In order to protect the heating pipe from overheating damage, ensure the stable operation and safe use of the heating pipe, the relay can be used to control the on-off of the heating pipe. In another aspect, the relay can play a protection role in the heating pipe, the temperature of the heating pipe can be monitored by the relay, and the power supply can be cut off when the set value is reached, thereby preventing the heating pipe from overheating. The relay can also play an automatic control role. The relay can realize the automatic control of the heating pipe by cooperating with other control elements such as temperature sensors, thereby improving the heating efficiency and comfort.

[0048] The embodiments of the present application are improved in order to reduce the phenomenon of dry burning of the heating pipe caused by the failure of the relay due to the sticking of the relay contacts. Of course, the occurrence of the dry burning phenomenon of the heating pipe is not limited to the above reason, and the embodiments of the present application can be solved together.

[0049] Exemplarily, the heating pipe of the embodiments of the present application can be connected with the relay, and then connected with the live wire through the relay and the door lock. That is, the heating pipe is not only controlled by the relay, but also affected by the unlocking and locking of the door lock, thereby reducing the risk of dry burning of the heating pipe.

[0050] Exemplarily, one end of the heating pipe is connected with the zero line through the relay, and the other end of the heating pipe is connected with the live wire through the door lock. When the door lock is closed, the live wire is connected with the door lock, and at this time the heating pipe is connected with the live wire. When the door lock is closed, the connection and disconnection of the heating pipe with the zero line can be controlled by controlling the switch of the relay. When the door lock is closed, if the relay fails, the heating pipe can be directly connected with the zero line, and the heating pipe can always work, thereby causing the water temperature in the drum of the clothes treatment device to continuously rise. When the door lock is opened or unlocked, the heating pipe is disconnected with the live wire, and even if the relay fails, the heating pipe will not work.

[0051] In the working process, the temperature in the drum of the clothes treatment device needs to be detected first, such as the real-time temperature in the drum can be obtained by collecting the feedback signal of the temperature sensor, when the collected temperature in the drum is higher than the first temperature threshold such as the maximum washing temperature for a certain time, and the temperature sensor is normal, it can be determined that the heating water temperature is abnormal. The maximum washing temperature of different models of clothes treatment devices is different, that is, the first temperature threshold is related to the model of the clothes treatment device, but the first temperature threshold fluctuates around a certain set value.

[0052] Exemplarily, the temperature in the drum of the clothes treatment device can be detected by using a temperature sensor such as a thermistor NTC.

[0053] For example, the first temperature threshold can be determined according to the processing temperature of the clothes treatment apparatus on clothes and experience value. For example, the processing temperature of the clothes treatment apparatus on clothes is 60 DEG C, which can realize drying of clothes and will not cause damage to clothes. According to experience value, when the processing temperature is 83 DEG C or more, the possibility of damage to clothes is large. Therefore, the first temperature threshold can be greater than 75 DEG C, for example, the first temperature threshold can be 83 DEG C.

[0054] When the temperature in the drum is greater than the first temperature threshold, the door lock is controlled to be unlocked, so that the heating pipe is disconnected from the live wire. At this time, even if the relay fails, the heating pipe will not work.

[0055] When the temperature in the drum exceeds the first temperature threshold, such as 83 DEG C, it can be determined that the temperature in the drum is abnormal. Therefore, the door lock can be controlled to be unlocked to disconnect the heating pipe and the live wire, so that the heating pipe stops working, thereby reducing the risk of dry burning of the heating pipe.

[0056] It should be noted that when the temperature in the drum exceeds the first temperature threshold, the door lock is unlocked at this time, and if the user approaches or puts his hand into the drum, there is a risk of being scalded. In order to reduce the risk of scalding of the user, when the temperature in the drum exceeds the first temperature threshold, the door lock can be controlled to be unlocked while an alarm prompt is issued to remind the user that the temperature in the drum is abnormally high at this time. For example, the alarm prompt can be displayed by issuing a software instruction and accompanied by a beeping sound. For another example, the alarm prompt can be a light reminder, which is more intuitive than the sound prompt, and will not cause noise interference to the user's life, nor will it cause the problem of missing alarm caused by interval prompt sound.

[0057] The heating control method provided by the embodiment of the present application connects the heating pipe to the live wire through the door lock, that is, the heating pipe is controlled by the door lock. When the temperature in the drum is abnormally high, the door lock can be unlocked to stop the heating pipe from working, thereby reducing the risk of dry burning of the heating pipe.

[0058] Before detecting the temperature in the drum, it can be determined whether the temperature sensor is normal, so as to reduce the temperature abnormality caused by failure of the temperature sensor.

[0059] For example, before step S110, the heating control method further comprises:

[0060] Detecting the working state of the temperature sensor in the drum.

[0061] If the working state of the temperature sensor is normal, detecting the temperature in the drum of the clothes treatment apparatus.

[0062] The working state of the temperature sensor in the detection cylinder is detected, the temperature sensor can be a thermistor NTC for example, and the working state of the thermistor NTC can be detected by detecting the resistance value of the thermistor NTC, and the working state of the temperature sensor can be determined by comparing the resistance value with the resistance change curve of the thermistor NTC. In addition, the detection of the temperature in the cylinder is performed when the working state of the temperature sensor is normal, so that the temperature abnormality caused by the temperature sensor can be excluded, and the accuracy of the control of the heating pipe can be improved.

[0063] When the temperature in the cylinder exceeds the first temperature threshold, the door lock is unlocked, which has the risk of scalding the user. In order to reduce the risk of scalding, in addition to the alarm prompt, the cylinder can be cooled before the door lock is unlocked.

[0064] For example, refer to Figure 2 , Figure 2 The second flowchart of the heating control method provided by the embodiment of the present application is shown. Step S120 comprises:

[0065] Step S121, when the temperature in the cylinder is greater than the first temperature threshold, the cylinder is cooled, and the cooling process comprises repeatedly filling water in the cylinder to the first water level and draining water to the second water level, the second water level being lower than the first water level.

[0066] Step S122, when the temperature in the cylinder is less than or equal to the second temperature threshold, the door lock is unlocked, wherein the second temperature threshold is less than the first temperature threshold.

[0067] For example, when the temperature in the cylinder is greater than the first temperature threshold, i.e. the temperature in the cylinder is abnormal, the cylinder is cooled, and the cooling process can be repeated by filling water in the cylinder to the first water level and draining water to the second water level, i.e. by water exchange to cool the cylinder.

[0068] The first water level needs to be no less than half the cylinder water level, and the second water level needs to be below the cylinder water level and above the heating protection water level. Therefore, the second water level is lower than the first water level.

[0069] It should be noted that this process needs to shield the water filling abnormality and water draining abnormality alarm.

[0070] The timing of the door lock unlocking can be when the temperature in the cylinder is less than or equal to the second temperature threshold, and the second temperature threshold is less than the first temperature threshold. The second temperature threshold can refer to the processing temperature of the clothes in the clothes treatment device, such as 60℃, or the processing temperature range of the clothes in the clothes treatment device is 50℃ to 65℃, and the second temperature threshold can be selected as 60℃.

[0071] When the temperature in the barrel is less than or equal to the second temperature threshold, that is, the requirement for unlocking the door lock is met, in order to avoid water leakage caused by the door body opening when the door lock is unlocked, the cooling process can be stopped at this time, such as draining the water in the barrel to a third water level, which can be a water level lower than the door seal, thereby preventing water leakage and disconnecting the heating pipe.

[0072] If the temperature in the barrel continues to be detected to be higher than the first temperature threshold, such as the processing time of the detected temperature being higher than the first temperature threshold reaching a maximum preset time, the operation of draining to the second water level is forcibly performed.

[0073] In the heating control method provided by the embodiments of the present application, the heating pipe is connected to the live wire through the door lock, that is, the heating pipe is controlled by the door lock, so that the door lock can be unlocked to stop the heating pipe from working when the temperature in the barrel is abnormally high, thereby reducing the risk of heating pipe dry burning accidents. Moreover, when the temperature in the barrel is abnormally high, the barrel is cooled first, and then the door lock is unlocked, thereby reducing the risk of users being scalded.

[0074] It should be noted that the unlocking state of the door lock is related to whether the heating pipe can stop working when the temperature is abnormally high, so the unlocking state of the door lock needs to be detected after the door lock unlocking instruction is sent, such as unlocking success and unlocking failure.

[0075] For example, after step S122, the heating control method further includes:

[0076] Step S123, detecting the unlocking state of the door lock.

[0077] Step S124, if the unlocking state of the door lock is unlocking success, stopping the cooling process.

[0078] Step S125, if the unlocking state of the door lock is unlocking failure, continuing to perform the cooling process.

[0079] The unlocking state of the door lock can be detected by detecting whether a feedback signal is received after sending an unlocking signal. If the unlocking signal is sent to the door lock, when the door lock is normal, such as receiving a feedback signal of door lock unlocking success; when the door lock is abnormal, such as not receiving the feedback signal of door lock unlocking success.

[0080] If the unlocking state of the door lock is unlocking success, the door lock circuit is automatically disconnected, and then the heating pipe relay contact is disconnected to make the heating pipe stop heating, thereby achieving the effect that the heating pipe does not dry burn due to circuit failure. At this time, the cooling process can be stopped, because the barrel has been cooled, and the door lock unlocking can make the heating pipe stop working, so the risk of heating pipe dry burning accident is low at this time, which can be used as a judgment condition for stopping the cooling process.

[0081] If the unlocking state of the door lock is unlocking failure, the probability of the heating tube dry burning accident is relatively large because the heating tube can not stop working, so the risk of the heating tube dry burning accident can be reduced by continuing the cooling treatment, and the cooling treatment is until unlocking success or power off, and the buzzer can intermittently emit an alarm prompt sound to remind the user to find the fault as soon as possible so as to take the power-off measure in time.

[0082] In order to reduce the occurrence of the heating tube dry burning accident, the cooling treatment can also be performed on the drum to achieve this purpose. When the cooling treatment is performed, the water in the drum is at least set at the second water level, and the water is in direct contact with the heating tube, so that the occurrence of the heating tube dry burning accident can be reduced.

[0083] For example, the heating tube is used to heat the drum of the clothes treatment device, such as the heating tube can be arranged at the bottom of the drum of the clothes treatment device to heat the drum, and then adjust the treatment of the clothes. In order to protect the heating tube from overheating damage and ensure stable operation and safe use, the relay can be used to control the on-off of the heating tube. In another aspect, the relay can play a protective role in the heating tube. The relay can monitor the temperature of the heating tube and cut off the power supply when the set value is reached, thereby preventing the heating tube from overheating. The relay can also play an automatic control role. The relay can cooperate with other control elements such as temperature sensors to realize automatic control of the heating tube, improve heating efficiency and comfort. Figure 3 Figure 3 The third flowchart of the heating control method provided by the embodiment of the present application. The embodiment of the present application also provides a heating control method, which comprises:

[0084] Step S210, detecting the temperature in the drum of the clothes treatment device.

[0085] Step S220, when the temperature in the drum is greater than the first temperature threshold, an alarm prompt information is sent and the drum is cooled, and the cooling treatment comprises repeatedly filling water in the drum to the first water level and draining water to the second water level, the second water level being lower than the first water level.

[0086] For example, the heating tube is used to heat the drum of the clothes treatment device, such as the heating tube can be arranged at the bottom of the drum of the clothes treatment device to heat the drum, and then adjust the treatment of the clothes. In order to protect the heating tube from overheating damage and ensure stable operation and safe use, the relay can be used to control the on-off of the heating tube. In another aspect, the relay can play a protective role in the heating tube. The relay can monitor the temperature of the heating tube and cut off the power supply when the set value is reached, thereby preventing the heating tube from overheating. The relay can also play an automatic control role. The relay can cooperate with other control elements such as temperature sensors to realize automatic control of the heating tube, improve heating efficiency and comfort.

[0087] In order to reduce the risk of the heating tube dry burning accident caused by the failure of the relay, the cooling treatment can be performed on the drum.

[0088] In the working process, the temperature in the drum of the clothes treatment device needs to be detected first. When the temperature in the drum is greater than the first temperature threshold, it can be determined that the temperature in the drum is abnormal. At this time, the cooling treatment can be performed on the drum, on the one hand, the temperature in the drum can be reduced to prevent the temperature from being too high to damage the internal components of the clothes treatment device; on the other hand, water can be maintained in the drum to reduce the risk of the heating tube dry burning accident.​

[0089] The cooling treatment can be implemented by repeatedly filling water in the drum to the first water level and draining water to the second water level, i.e., by water replacement.

[0090] The first water level needs to be no less than the half-drum water level, and the second water level needs to be below the drum water level and above the heating protection water level. Therefore, the second water level is lower than the first water level.

[0091] It should be noted that this process needs to shield the water filling abnormality and water draining abnormality alarms.

[0092] For example, the first temperature threshold can be determined according to the treatment temperature of the clothes treatment device on clothes as a reference and according to an empirical value. For example, the treatment temperature of the clothes treatment device on clothes is 60℃, which can achieve drying of clothes and will not cause damage to clothes. According to the empirical value, when the treatment temperature is 83℃ or higher, the possibility of damage to clothes is relatively large. Therefore, the first temperature threshold can be a value greater than 75℃, such as 83℃.

[0093] It should be noted that, in order to prevent the risk of water leakage and / or scalding due to the user opening the door during the cooling treatment, an alarm prompt can be issued when the temperature in the drum is detected to be greater than the first temperature threshold, while the drum is being cooled, to remind the user to pay attention. For example, the alarm prompt can be a light reminder, which is more intuitive than the sound prompt method, and will not cause noise interference to the user's life, nor will it cause the problem of missed alarm caused by interval prompt sound.

[0094] Of course, in order to prevent the problem of waste of water resources caused by temperature error detection of the temperature sensor and the triggered cooling treatment, the working state of the temperature sensor can be detected before detecting the temperature in the drum. For details, refer to the above description, which will not be repeated here.

[0095] In the heating control method provided by the embodiments of the present application, when the temperature in the drum is abnormally high, the drum is cooled, which can reduce the temperature in the drum and thus reduce the risk of the user being scalded, and can also maintain water in the drum and thus reduce the risk of dry burning of the heating pipe.

[0096] For example, after step S220, the heating control method further includes:

[0097] Step S230: when the temperature in the drum is less than or equal to the second temperature threshold, stopping the cooling treatment and maintaining the water level in the drum to the third water level, the third water level being lower than the second water level.

[0098] When the temperature in the drum falls to a second temperature threshold, such as 60℃, the cooling process can be stopped to save water resources. Also, to reduce the risk of dry burning of the heating pipe, the water level in the drum can be maintained at a third water level, which is less than the second water level, such as a height below the door seal.

[0099] Please refer to Figure 4 and Figure 5 , Figure 4 a structural block diagram of a heating control device provided by an embodiment of the present application, Figure 5 a circuit diagram of a heating control device provided by an embodiment of the present application. In order to better implement the heating control method of the present application, the present application further provides a heating control device 300 applied to a clothes treatment apparatus, which comprises a heating pipe and a door lock, and the heating pipe is connected to a live wire L through the door lock. Exemplarily, one end of the heating pipe is connected to a zero line through a relay, and the other end of the heating pipe is connected to the live wire L through the door lock. When the door lock is closed, the live wire L is connected to the door lock, and at this time, the heating pipe is connected to the live wire L. When the door lock is closed, the connection and disconnection of the heating pipe to the zero line N can be controlled by controlling the switch of the relay. When the door lock is closed, if the relay fails, the heating pipe may be directly connected to the zero line, and the heating pipe will always work, causing the water temperature in the drum of the clothes treatment apparatus to continuously rise. When the door lock is opened or unlocked, the heating pipe is disconnected from the live wire L, and even if the relay fails, the heating pipe will not work.

[0100] Exemplarily, the heating control device 300 comprises a temperature sensor 310 and a controller 320.

[0101] The temperature sensor 310 is arranged in the drum of the clothes treatment apparatus, and is used to detect the temperature in the drum of the clothes treatment apparatus. For example, the temperature sensor 310 can be a thermistor.

[0102] The controller 320 is connected to the temperature sensor 310 and the door lock respectively, and is used to output an unlocking signal to unlock the door lock according to the temperature in the drum input by the temperature sensor 310, and disconnect the heating pipe from the live wire L.

[0103] In the heating control device 300 provided by the present application, the heating pipe is connected to the live wire L through the door lock, that is, the heating pipe is controlled by the door lock, and the door lock can be unlocked to stop the heating pipe from working when the temperature in the drum is abnormally high, thereby reducing the risk of dry burning of the heating pipe.

[0104] Exemplarily, the heating control device 300 further comprises a washing valve 330 and a drainage valve 340. One end of the washing valve 330 is connected to the zero line N, and the other end of the washing valve 330 is connected to the heating pipe. One end of the drainage valve 340 is connected to the zero line N, and the other end of the drainage valve 340 is connected to the heating pipe.

[0105] The controller 320 is also connected with the washing valve 330 and the draining valve 340, and is configured to output a cooling signal to make the washing valve 330 and the draining valve 340 work alternately according to the temperature in the drum input by the temperature sensor 310, and repeat the processes of water filling to the first water level and water draining to the second water level, which is lower than the first water level.

[0106] For example, the heating control device 300 further comprises a first transistor 350 and a second transistor 360. The first transistor 350 is connected between the washing valve 330 and the zero line N, and the second transistor 360 is connected between the draining valve 340 and the zero line N.

[0107] For example, the washing valve 330 and the first transistor 350 are in a one-to-one correspondence, such as the washing valve 330 can have two, such as one is a main washing valve and the other is a pre-washing valve, and the corresponding two first transistors 350 are connected to the main washing valve and the zero line N and the pre-washing valve and the zero line N, respectively.

[0108] Correspondingly, the embodiment of the present application also provides a laundry treating apparatus (the structure of the laundry treating apparatus is not shown in the figure). The laundry treating apparatus can be a washing machine, a drying machine or a washing-drying integrated machine. The laundry treating apparatus can comprise a heating pipe and a door lock, and the heating pipe is connected with the live line L through the door lock.

[0109] Of course, the laundry treating apparatus is not limited to the above-mentioned devices, and also has a door body, a box body, a display screen and the like. The above-mentioned are only examples and should not be understood as a limitation to the laundry treating apparatus.

[0110] Please refer to Figure 6 , Figure 6 The structure block diagram of the laundry treating apparatus provided by the embodiment of the present application is shown in the figure. The laundry treating apparatus 400 can further comprise a processor 410 with one or more processing cores, a memory 420 with one or more computer readable storage media, and a computer program stored in the memory 420 and executable on the processor 410.
