Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the application will be more thoroughly understood, and will fully convey the scope of the application to those skilled in the art.

It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the usual meanings understood by those skilled in the art to which this application belongs.

The following describes a heating control method, a device, a clothes treatment device, and a storage medium according to the embodiments of the present application with reference to the accompanying drawings.

An embodiment of the present application provides a heating control method, which is applied to a laundry treatment device. The laundry treatment device may be a single-tub washing machine, a double-tub washing machine, or a washing machine with more washing tubs. The washing method can be drum type or pulsator type.

Each washing tub of the laundry treatment device is equipped with a corresponding main control board, a heating tube, and a relay corresponding to the heating tube. For a certain washing tub, a heating pipe is provided at the bottom of the washing tub, and the heating pipe is connected to the main control board corresponding to the washing tub through a relay. The execution body of the embodiment of the present application may be the main control board corresponding to the washing tub, and the main control board determines whether the relay of the heating tube of the washing tub controlled by the main control board has a failure such as adhesion by using the method provided in the embodiment of the present application, and the Drain the water in the washing tub after confirming that the relay has a failure such as sticking. For example, drain all the water in the washing tub, or drain part of the water in the washing tub. Therefore, the temperature of the heating tube at the bottom of the washing tub rises rapidly, and the fuse in the heating tube is blown, so that the heating tube cannot continue to be heated, thereby avoiding the occurrence of simultaneous heating of multiple washing tubs, and avoiding the heating of the laundry treatment equipment. The power exceeds the rated power of the power cord or power socket, reducing safety problems caused by faults such as relay adhesion.

The main control board corresponding to each washing tub of the laundry treatment device can perform relay adhesion protection by the method provided by the embodiment of the present application. Referring to FIG. 1 , the method specifically includes the following steps:

Step 101: Acquire a heating flag bit used to identify the working state of the heating tube.

The laundry treatment equipment controls the opening or closing of the heating tube through the main control board. The main control board maintains a heating flag bit used to identify the working state of the heating tube, and the working state of the heating tube is represented by a preset character, such as character 1. Indicates the open state, and the character 0 is used to indicate the closed state; or, the character 01 is used to indicate the open state, and the character 10 is used to indicate the closed state, etc.

When the main control board sends a control signal for turning on the heating tube to the relay corresponding to the heating tube, it also sets the heating flag position as a character used to indicate the opening state. When the main control board sends a control signal to turn off the heating tube to the relay, the heating flag is set to a character used to indicate the off state.

In the embodiment of the present application, when the user turns on the clothes treatment device, and the main control board is powered on and detects a start signal, the main control board reads the value of the heating flag.

Step 102: According to the heating flag indicating that the heating pipe is in a closed state, determine the current consecutive times that the water temperature in the washing tub satisfies the preset temperature rise condition.

The main control board determines the current working state of the heating tube according to the value of the heating flag bit read in step 101 . It is assumed that the character 1 is preset to indicate the open state, and the character 0 is to indicate the closed state. Then, if the value of the heating flag bit read by the main control board is 1, it is determined that the current working state of the heating tube is the ON state. If the value of the read heating flag bit is 0, it is determined that the current working state of the heating tube is the off state.

If it is determined that the value of the heating flag indicates that the heating tube is in the off state, it means that the main control board has previously sent a control signal to the relay of the heating tube to turn off the heating tube. Turn off and continue to heat, the water temperature in the washing tub will continue to rise. Therefore, on the premise that the heating flag indicates that the heating tube is in the off state, detecting the change of the water temperature in the washing tub is helpful to determine whether the relay of the heating tube is stuck or not.

In the embodiment of the present application, the main control board indicates that the heating pipe is in a closed state according to the heating flag, and determines the current consecutive times that the water temperature in the washing tub satisfies the preset temperature rise condition. A temperature sensor is arranged in the washing tub of the laundry treatment device, the temperature sensor is connected with the main control board, and the temperature of the water in the washing tub is detected by the temperature sensor. The preset temperature rise condition can be that the time period for which the temperature value of the water temperature rises exceeds the preset temperature value is less than or equal to the preset time period, the preset temperature value can be 2 degrees or 3 degrees, etc., and the preset time period can be 4 minutes or 5 minutes wait. The embodiments of the present application do not limit the specific values of the preset temperature value and the preset duration, which may be set according to requirements in practical applications.

The main control board indicates that the heating pipe is in a closed state according to the heating flag, and firstly determines the temperature rise time for the water temperature in the washing tub to rise to the preset temperature value. When the main control board determines that the heating flag indicates that the heating pipe is in a closed state, it obtains the current water temperature in the washing tub through the temperature sensor. A first detection time corresponding to the water temperature. Since the water temperature does not rise rapidly after heating, but there is a certain buffer time, the water temperature rises slowly in the early stage, so after confirming that the heating tube is in the closed state, the first water temperature can be obtained after a certain period of time. Check the water temperature after 1 or 2 minutes.

After acquiring the first water temperature and its corresponding first detection time, the water temperature in the washing tub is acquired in real time through the temperature sensor. In this embodiment of the present application, the real-time acquired water temperature is referred to as the second water temperature, and the second detection corresponding to the second water temperature is recorded. time. Each time the second water temperature and the second detection time corresponding to the second water temperature are obtained, the main control board calculates the difference between the second water temperature and the first water temperature, and compares the difference with the preset temperature value. If the difference is smaller than the preset temperature value, the sensor continues to acquire the second water temperature in the washing tub in real time. If the difference is greater than or equal to the preset temperature, calculate the difference between the second detection time corresponding to the second water temperature and the first detection time corresponding to the first water temperature, and determine the difference as the water in the washing tub The temperature rise time used to raise the preset temperature value. Then compare the temperature rise duration with the preset duration, if the temperature rise duration is less than or equal to the preset duration, it is determined that the temperature of the water in the washing tub has increased by the preset temperature value within the preset duration, and the temperature rise is determined this time. It is due to the temperature rise caused by the heating of the heating tube. Eliminate the possibility that the water temperature rises due to changes in the ambient temperature, determine that the water temperature in the washing tub satisfies the preset temperature rise condition, and add the current consecutive times that the water temperature in the washing tub meets the preset temperature rise condition. 1.

In the embodiment of the present application, if it is determined that the above-mentioned temperature rise duration is greater than the preset duration, it is considered that the temperature rise this time is caused by the change of the ambient temperature, rather than the heating of the heating pipe, and at this time, it is considered that the heating flag indicates the heating The tube is in a closed state, and the heating tube is actually in a closed state. The relay corresponding to the heating tube has no problems such as sticking, so the current consecutive times that the water temperature in the washing tub meets the preset temperature rise condition is reset to zero.

In some embodiments of the present application, if the main control board determines that the value of the heating flag indicates that the heating tube is in an on state, it means that the main control board has previously sent a control signal to the relay for turning on the heating tube, and the heating tube is turned on. If it belongs to the normal washing program, the above-mentioned current consecutive times will be reset to zero.

Step 103: It is determined that the current consecutive number of times is greater than or equal to the preset number of times, and the drain pump is controlled to drain the water in the washing tub.

After determining the current continuous number of times that the water temperature in the washing tub meets the preset temperature rise condition through the above step 102, compare the current continuous number of times with the preset number of times. The value of the preset number of times can be set as required in practical applications.

If it is compared that the current consecutive times is greater than or equal to the preset times, it means that the water temperature in the washing tub continues to rise even when the main control board controls the heating pipe to be turned off, indicating that the heating pipe is not actually turned off, so it can be determined that the heating pipe The corresponding relay is stuck and other failures occur.

In the case of a failure such as adhesion of the relay, the main controller cannot effectively control the heating tube, and the heating tube will continue to heat. In order to avoid the safety problem caused by the continuous heating of the heating tube, the embodiment of the present application determines that the relay has a failure such as adhesion. Then, the drain pump connected to the water outlet of the washing tub is controlled to start, and the water in the washing tub is discharged through the drain pump. After the water in the washing tub is discharged, the heating tube continues to heat, the temperature of the heating tube will rise rapidly, and the fuse in the heating tube will be blown. After the fuse is blown, the heating tube will no longer work, thus avoiding the safety problem caused by the constant heating of the heating tube. After the fuse is blown, although the washing tub corresponding to the heating tube no longer has the heating function, other washing functions such as rinsing and dehydration can still be used normally.

Because under normal circumstances, the temperature of the heating tube itself is high after the heating tube is turned off, which will cause the water temperature in the washing tub to continue to rise until the temperature of the heating tube is less than or equal to the water temperature in the washing tub. Therefore, if the main control board compares that the current consecutive number of times that the water temperature in the washing tub meets the preset temperature rise condition is less than the preset number of times, the increase in the water temperature in the washing tub may be caused by the relay sticking and other faults causing the heating tube to continue to heat. It may also be due to the high temperature of the heating tube after the heating tube is turned off. Therefore, when the current consecutive number of times is less than the preset number of times, return to step 101 to re-obtain the heating flag bit used to identify the working state of the heating tube, and execute steps 101-103 cyclically. until it is determined that the current consecutive number of times is greater than or equal to the preset number of times, it is determined that the relay corresponding to the heating tube has a failure such as adhesion, and the drain pump is controlled to drain the water in the washing tub.

In the embodiment of the present application, a fault flag may also be maintained in the main control board, and the main control board detects that the laundry treatment device is started, and sets the fault flag as a preset identifier, and the preset identifier may be 1 or 01 etc. The fault flag bit is used to identify a fault such as relay adhesion. In step 103, it is determined that the number of consecutive times is greater than or equal to the preset number of times, and the fault flag bit is cleared after it is determined that the relay corresponding to the heating tube has a fault such as adhesion. Or, in the entire washing process, the current consecutive times are less than the preset times, and no faults such as relay adhesion are determined, and the fault flag is cleared at the end of the washing program.

In order to facilitate the understanding of the relay adhesion protection solution provided by the embodiments of the present application, the following description is made with reference to the accompanying drawings. As shown in FIG. 2 , S1 : It is detected that the laundry treatment device is started, and the fault flag position is set as a preset identifier. S2: Determine whether the heating tube is in a closed state according to the heating flag, if yes, execute step S3, if not, execute step S12. S3: Determine whether there is a delay after the heating tube is turned off for a certain period of time, if yes, execute step S4, if not, continue to execute step S3. S4: Obtain the current first water temperature in the washing tub and its corresponding first detection time. S5: Acquire the second water temperature in the washing tub and the second detection time corresponding to the second water temperature in real time. S6: Determine whether the temperature difference between the second water temperature and the first water temperature is greater than or equal to the preset temperature value, if yes, go to step S7, if not, go to step S5. S7: Determine whether the time difference between the second detection time and the first detection time is less than or equal to the preset duration, if yes, go to step S8, if not, go to step S12. S8: Add one to the current continuous number of times that the water temperature in the washing tub satisfies the preset temperature rise condition. S9: Determine whether the current consecutive number of times is greater than or equal to the preset number of times, and if so, execute step S10, and if not, execute step S2. S10: Clear the fault flag bit. S11: It is determined that the relay corresponding to the heating tube has a failure such as adhesion, and the drain pump is controlled to discharge the water in the washing tub, and then the heating tube is dry-burned to blow the fuse. S12: Clear the current consecutive times to zero, and then execute step S2.

In the embodiment of the present application, when the heating flag in the main control board indicates that the heating pipe is in a closed state, the change of the water temperature in the washing tub is detected, and the current consecutive times that the water temperature meets the preset temperature rise condition are recorded, and the current consecutive times exceed the preset times. , indicating that the water temperature is raised by the heating of the heating tube, indicating that the main control board controls the relay to turn off the heating tube through the control signal, but in fact the heating tube is not turned off, so it can be determined that the relay has a failure such as adhesion. . At this time, the drain pump is controlled to discharge the water in the washing tub. After the water in the washing tub is discharged, the heating tube continues to heat, the temperature of the heating tube will rise rapidly, and the fuse in the heating tube will be blown. After the fuse is blown, the heating tube will no longer work. , so as to avoid the situation that multiple washing tubs are heated at the same time, to avoid the heating power of the laundry treatment equipment exceeding the rated power of the power cord or the power socket, and to avoid the safety problem caused by the constant heating of the heating tube.
