[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with 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 of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0041] Clothes processing equipment is a device that processes clothes, such as washing, spinning, and drying. Clothes processing equipment may be washing machines, dryers, and washer-dryers. Clothes processing equipment usually has the function of heating water to improve the washing effect or dry clothes. The treatment method for abnormally high temperature in the drum is usually to close the door lock and turn off all loads. However, this method has limitations. When the temperature is abnormally high due to adhesion of the heating tube relay contacts, this treatment method cannot directly turn off the heating tube, resulting in the heating tube still being in an abnormal working state, which can easily cause a dry burning accident of the heating tube.

[0042] Based on this, the present application provides a heating control method, device and clothing processing equipment, which will be described below in conjunction with the accompanying drawings.

[0043] See also Figure 1 As shown, Figure 1 The first flow chart of the heating control method provided in the embodiment of the present application is shown in FIG.

[0044] Step S110: detecting the temperature inside the drum of the clothes processing equipment.

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

[0046] The clothes processing device includes a heating pipe and a door lock, and the heating pipe is connected to the live wire through the door lock. Of course, the clothes processing device is not limited to the above components, and may also include components such as a door body, a box body, a display panel, etc., which are not limited here.

[0047] Exemplarily, the heating tube is used to heat the inside of the drum of the clothing processing device. For example, the heating tube can be arranged at the bottom of the drum of the clothing processing device to achieve heating inside the drum, thereby adjusting the treatment of the clothing. Among them, in order to protect the heating tube from overheating damage and ensure its stable operation and safe use, the on and off of the heating tube can be controlled by a relay. In other words, the relay can play a protective role in the heating tube. The adder 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 and improve heating efficiency and comfort.

[0048] The embodiment of the present application is an improvement made to reduce the phenomenon of dry burning of the heating tube caused by relay failure due to adhesion of the relay contacts. Of course, the occurrence of the dry burning of the heating tube is not limited to the above reasons, and the embodiment of the present application can solve them together.

[0049] For example, the heating tube of the embodiment of the present application can be connected to the relay, and then connected to the live wire through the relay and the door lock in sequence. That is, the heating tube is not only controlled by the relay, but the unlocking and locking of the door lock will also affect the operation of the heating tube, thereby reducing the risk of dry burning accidents of the heating tube.

[0050] Exemplarily, one end of the heating tube is connected to the neutral wire through a relay, and the other end of the heating tube is connected to the live wire through a door lock. When the door lock is closed, the live wire is connected to the door lock, and the heating tube is connected to the live wire at this time. When the door lock is closed, the connection and disconnection of the heating tube and the neutral wire can be controlled by controlling the switch of the relay. When the door lock is closed, if the relay fails, the heating tube may be directly connected to the neutral wire, and the heating tube will continue to work, causing the water temperature in the drum of the clothing processing device to continue to rise. When the door lock is disconnected or unlocked, the heating tube is disconnected from the live wire, and the heating tube will not work even if the relay fails.

[0051] During operation, it is necessary to first detect the temperature in the drum of the clothing processing device, such as by collecting the real-time temperature in the drum through the feedback signal of the temperature sensor. When the temperature in the drum is collected to be higher than the first temperature threshold, such as the maximum washing temperature, for a certain period of time, and there is no abnormality in the temperature sensor, it can be determined that the heating water temperature is abnormal. Among them, the maximum washing temperature of different models of clothing processing devices is different, that is, the first temperature threshold is related to the model of the clothing processing device, but the first temperature threshold fluctuates around a certain set value.

[0052] Exemplarily, detecting the temperature in the drum of the laundry processing device may be achieved using a temperature sensor, such as a thermistor NTC.

[0053] Exemplarily, the selection of the first temperature threshold can be based on the processing temperature of the clothes by the clothing processing equipment as a reference and determined based on empirical values. For example, the processing temperature of the clothes by the clothing processing equipment is 60°C. This temperature can dry the clothes without causing any damage to the clothes. According to empirical values, when the processing temperature is 83°C or exceeds 83°C, the possibility of damage to the clothes is greater. Therefore, the first temperature threshold can be a value greater than 75°C, such as 83°C.

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

[0055] When the temperature inside the barrel exceeds a first temperature threshold, such as 83°C, it can be determined that the temperature inside the barrel is abnormal, so the door lock can be controlled to unlock to disconnect the heating tube and the fire wire, so that the heating tube stops working, thereby reducing the risk of dry burning accidents of the heating tube.

[0056] It should be noted that when the temperature in the barrel exceeds the first temperature threshold, the door lock is unlocked. If the user approaches or puts his hand into the barrel, there is a risk of scalding. In order to reduce the risk of scalding for the user, when the temperature in the barrel exceeds the first temperature threshold, the door lock can be controlled to unlock and an alarm can be issued at the same time to remind the user that the temperature in the barrel is abnormally high at this time. For example, an alarm prompt can be displayed by issuing a software instruction accompanied by a beep. For another example, the alarm prompt can be a light reminder, which is more intuitive than a sound prompt, and there will be no noise interfering with the user's life, nor will there be a problem of missed alarms caused by interval prompt sounds.

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

[0058] Before detecting the temperature in the cylinder, it is possible to first confirm whether the temperature sensor is normal, so as to reduce the temperature abnormality caused by the failure of the temperature sensor.

[0059] Exemplarily, before step S110, the heating control method further includes:

[0060] Check the working status of the temperature sensor in the cylinder.

[0061] If the working state of the temperature sensor is normal, the temperature inside the drum of the clothes processing device is detected.

[0062] The working state of the temperature sensor in the cylinder is detected. The temperature sensor may be, for example, a thermistor NTC. The working state of the thermistor NTC may be detected by, for example, detecting the resistance value of the thermistor NTC. By comparing the resistance change curve thereof, the working state of the temperature sensor may be determined. Moreover, the detection of the temperature in the cylinder in the embodiment of the present application is performed when the working state of the temperature sensor is normal, thereby eliminating the abnormal temperature caused by the temperature sensor and improving the accuracy of the control of the heating tube.

[0063] Among them, when the temperature inside the barrel exceeds the first temperature threshold, there is a risk of scalding the user when the door lock is unlocked. To reduce the risk of scalding, in addition to the alarm prompt, the barrel can also be cooled before controlling the door lock to unlock.

[0064] For example, see Figure 2 , Figure 2 This is a second flow chart of the heating control method provided in the embodiment of the present application. Step S120 includes:

[0065] Step S121, when the temperature in the drum is greater than the first temperature threshold, cooling treatment is performed on the drum, the cooling treatment includes repeatedly filling water into the drum to a first water level and draining water to a second water level, the second water level being lower than the first water level.

[0066] Step S122: When the temperature inside the barrel is less than or equal to a second temperature threshold, the door lock is controlled to be unlocked, wherein the second temperature threshold is less than the first temperature threshold.

[0067] Exemplarily, when the temperature inside the barrel is greater than a first temperature threshold, that is, when the temperature inside the barrel is abnormal, cooling treatment is performed on the barrel. The cooling treatment may be performed by, for example, repeatedly filling the barrel with water to a first water level and draining the water to a second water level, that is, cooling the barrel by changing the water.

[0068] Among them, the first water level needs to be not less than the half-barrel water level, and the second water level needs to be below the barrel edge 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 requires shielding the abnormal water inlet and abnormal drainage alarms.

[0070] The timing for unlocking the door lock may be when the temperature inside the drum is less than or equal to a second temperature threshold, and the second temperature threshold is less than the first temperature threshold, wherein the second temperature threshold may refer to the processing temperature of the clothes by the clothing processing device, such as 60°C, or, the processing temperature range of the clothes by the clothing processing device is 50°C to 65°C, and the second temperature threshold may be selected as 60°C, for example.

[0071] Among them, 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 opening of the door body 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. The third water level 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 drum is continuously detected to exceed the first temperature threshold, such as the processing time of the detected temperature exceeding the first temperature threshold reaches a maximum preset time, the operation of draining water to the second water level is forcibly executed.

[0073] In the heating control method provided in the embodiment of the present application, the heating tube is connected to the live wire through the door lock, that is, the heating tube is controlled by the door lock, and the door lock can be unlocked to stop the heating tube from working when the temperature inside the tube is abnormally high, thereby reducing the risk of dry burning of the heating tube. In addition, when the temperature inside the tube is abnormally high, the tube is cooled first, and then the door lock is unlocked, which can reduce 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 tube can stop working when the temperature is abnormal. Therefore, it is necessary to detect the unlocking state of the door lock after sending the door lock unlocking command. The unlocking state includes unlocking success and unlocking failure.

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

[0076] Step S123: Detect the unlocking state of the door lock.

[0077] Step S124: If the unlocking state of the door lock is unlocked successfully, stop the cooling process.

[0078] Step S125: If the unlocking state of the door lock is unlocking failure, continue to perform the cooling process.

[0079] The unlocking status of the door lock can be detected by, for example, detecting whether a feedback signal is received after sending an unlocking signal. If an unlocking signal is sent to the door lock, when the door lock is normal, a feedback signal indicating successful unlocking of the door lock will be received; when the door lock is abnormal, no feedback signal indicating successful unlocking of the door lock will be received.

[0080] If the door lock is unlocked successfully, the door lock circuit is automatically disconnected, and then the heating tube relay contacts are disconnected, causing the heating tube to be powered off and stop heating, ultimately achieving the effect of preventing the heating tube from burning dry due to circuit failure. At this time, the cooling process can be stopped, because the tube has been cooled, and the door lock unlocking can stop the heating tube from working. At this time, the risk of the heating tube burning dry is low, and this can be used as a judgment condition for stopping the cooling process.

[0081] If the unlocking status of the door lock is unlocking failure, the heating tube may not be able to stop working, and the probability of dry burning of the heating tube is relatively high. Therefore, the risk of dry burning of the heating tube can be reduced by continuing the cooling process until the unlocking is successful or the power is cut off. During this process, the buzzer can intermittently sound an alarm to remind the user to discover the fault as early as possible so as to take power-off measures in time.

[0082] In order to reduce the occurrence of dry-burning accidents of the heating tube, it can also be achieved by cooling the inside of the tube. During the cooling process, the amount of water in the tube will at least be set to the second water level, and the water will always be in contact with the heating tube, thereby reducing the occurrence of dry-burning accidents of the heating tube.

[0083] For example, Figure 3 , Figure 3 The third flow chart of the heating control method provided in the embodiment of the present application. The embodiment of the present application also provides a heating control method, including:

[0084] Step S210: Detect the temperature inside the drum of the clothing processing equipment.

[0085] Step S220: When the temperature in the barrel is greater than the first temperature threshold, an alarm message is issued and the barrel is cooled. The cooling process includes repeatedly filling the barrel with water to a first water level and draining the water to a second water level, wherein the second water level is lower than the first water level.

[0086] Exemplarily, the heating tube is used to heat the inside of the drum of the clothing processing device. For example, the heating tube can be arranged at the bottom of the drum of the clothing processing device to achieve heating inside the drum, thereby adjusting the treatment of the clothing. Among them, in order to protect the heating tube from overheating damage and ensure its stable operation and safe use, the on and off of the heating tube can be controlled by a relay. In other words, the relay can play a protective role in the heating tube. The adder 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 and improve heating efficiency and comfort.

[0087] In order to reduce the risk of dry burning of the heating tube due to relay failure, the inside of the tube can be cooled.

[0088] During the working process, it is necessary to first detect the temperature inside the drum of the clothing processing equipment. When the temperature inside the drum is greater than the first temperature threshold, it can be determined that the temperature inside the drum is abnormal. At this time, the drum can be cooled. On the one hand, the temperature inside the drum can be lowered to prevent damage to the internal components of the clothing processing equipment caused by excessive temperature; on the other hand, water can be maintained in the drum to reduce the risk of dry burning accidents of the heating tube.

[0089] The cooling treatment may be performed by repeatedly filling the drum with water to a first water level and draining the drum to a second water level, that is, by changing the water to achieve cooling treatment in the drum.

[0090] Among them, the first water level needs to be not less than the half-barrel water level, and the second water level needs to be below the barrel edge 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 requires shielding the abnormal water inlet and abnormal drainage alarms.

[0092] Exemplarily, the selection of the first temperature threshold can be based on the processing temperature of the clothes by the clothing processing equipment as a reference and determined based on empirical values. For example, the processing temperature of the clothes by the clothing processing equipment is 60°C. This temperature can dry the clothes without causing any damage to the clothes. According to empirical values, when the processing temperature is 83°C or exceeds 83°C, the possibility of damage to the clothes is greater. Therefore, the first temperature threshold can be a value greater than 75°C, such as 83°C.

[0093] It should be noted that in order to prevent the risk of water leakage and / or scalding caused by the user opening the door during the cooling process, when the temperature inside the barrel is detected to be greater than the first temperature threshold, an alarm prompt can be issued while the barrel 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 there will be no noise interfering with the user's life, and there will be no problem of missed alarms caused by interval prompt sounds.

[0094] Of course, in order to prevent the problem of temperature misdetection due to abnormal temperature sensor and the cooling process triggered thereby, which wastes water resources, the working status of the temperature sensor can be detected before detecting the temperature inside the barrel. For details, please refer to the above description and will not be repeated here.

[0095] In the heating control method provided in the embodiment of the present application, when the temperature inside the barrel is abnormally high, the barrel is cooled. On the one hand, the temperature inside the barrel can be lowered, thereby reducing the risk of scalding the user; on the other hand, water can be maintained in the barrel, thereby reducing the risk of dry burning accidents of the heating tube.

[0096] Exemplarily, 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, the cooling process is stopped, and the water level in the drum is maintained at a third water level, which is lower than the second water level.

[0098] When the temperature in the cylinder drops to a second temperature threshold, such as 60°C, the cooling process can be stopped to save water resources. In addition, in order to reduce the risk of dry burning of the heating tube, the water level in the cylinder can be maintained at a third water level, which is lower than the second water level. The third water level can be, for example, lower than the height of the door seal.

[0099] See also Figure 4 and Figure 5 , Figure 4 This is a structural block diagram of the heating control device provided in an embodiment of the present application. Figure 5 A circuit diagram of a heating control device provided in an embodiment of the present application. In order to better implement the heating control method of an embodiment of the present application, an embodiment of the present application also provides a heating control device 300, which is applied to a clothing processing device, and the clothing processing device includes a heating tube and a door lock, and the heating tube is connected to the live wire L through the door lock. Exemplarily, one end of the heating tube is connected to the neutral wire through a relay, and the other end of the heating tube 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 the heating tube is connected to the live wire L. When the door lock is closed, the connection and disconnection of the heating tube and the neutral wire N can be controlled by controlling the switch of the relay. When the door lock is closed, if the relay fails, the heating tube may be directly connected to the neutral wire, and the heating tube will continue to work, causing the water temperature in the drum of the clothing processing device to continue to rise. When the door lock is disconnected or unlocked, the heating tube is disconnected from the live wire L, and even if the relay fails, the heating tube will not work.

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

[0101] The temperature sensor 310 is disposed in the drum of the laundry processing device, and is used to detect the temperature in the drum of the laundry processing device. For example, the temperature sensor 310 may be a thermistor.

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

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

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

[0105] The controller 320 is also connected to the washing valve 330 and the drain valve 340. The controller 320 is also used to output a cooling signal to make the washing valve 330 and the drain valve 340 work alternately according to the temperature in the drum input by the temperature sensor 310, and repeatedly let water into the drum to a first water level and drain water to a second water level, and the second water level is lower than the first water level.

[0106] Exemplarily, the heating control device 300 further includes a first transistor 350 and a second transistor 360. The first transistor 350 is connected between the wash valve 330 and the neutral line N, and the second transistor 360 is connected between the drain valve 340 and the neutral line N.

[0107] Among them, the number of washing valves 330 and first transistors 350 corresponds. For example, there can be two washing valves 330, such as one is a main wash valve and the other is a pre-wash valve. The corresponding two first transistors 350 are respectively connected to the main wash valve and the zero line N and to the pre-wash valve and the zero line N.

[0108] Accordingly, the embodiment of the present application further provides a clothing processing device (the structure of the clothing processing device is not shown in the figure). The clothing processing device may be, for example, a washing machine, a dryer, or a washing and drying machine. The clothing processing device may include a heating pipe and a door lock, and the heating pipe is connected to the live wire L through the door lock.

[0109] Of course, the clothing processing device is not limited to the above-mentioned devices, but also has structures such as a door body, a box body, and a display screen. The above-mentioned are only examples and should not be understood as limitations on the clothing processing device.

[0110] See also Figure 6 , Figure 6 A structural block diagram of a clothing processing device provided in an embodiment of the present application. The clothing processing device 400 may also include a processor 410 having one or more processing cores, a memory 420 having one or more computer-readable storage media, and a computer program stored in the memory 420 and executable on the processor 410. The processor 410 is electrically connected to the memory 420. Those skilled in the art will appreciate that the structure of the clothing processing device 400 shown in the figure does not constitute a limitation on the clothing processing device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange components differently.
