Description

Technical Field

[0001] This application relates to the field of washing machine control technology, specifically to a washing machine heating control method, device, washing machine, and readable storage medium. Background Technology

[0002] Twin-drum washing machines are gradually becoming commonplace in households, allowing customers to place laundry into both drums for separate washing, simultaneous drying, and simultaneous heating. However, because the drying and water heaters in twin-drum washing machines have high power ratings, exceeding the specified power consumption for Class I household appliances and the current carrying capacity of household cables, existing twin-drum washing machines prevent the second drum from entering the water or drying heating phase while the first drum is in operation. Instead, the second drum operates at a low speed for an extended period until the first drum has finished its water or drying heating process. This results in longer running times and higher energy consumption for simultaneous heating in both drums.

[0003] Therefore, how to reduce the long running time and energy consumption of washing machines with simultaneous dual-drum heating is an urgent problem to be solved. Summary of the Invention

[0004] This application provides a washing machine heating control method, device, washing machine, and readable storage medium, which can reduce the long running time and power consumption of the dual-drum synchronous heating of the washing machine.

[0005] In a first aspect, embodiments of this application provide a washing machine heating control method, the method comprising:

[0006] Obtain the operating status information of the first washing drum;

[0007] If it is determined from the operating condition information that the first washing drum is in the heating process, then the first temperature, the load of clothes and the humidity inside the drum of the first washing drum, and the second temperature of the second washing drum are obtained.

[0008] Based on the first temperature, the load of clothes, the humidity inside the drum, and the second temperature, the second washing drum is controlled to heat up.

[0009] Secondly, embodiments of this application provide a washing machine heating control device.

[0010] The first acquisition unit is used to acquire the operating condition information of the first washing drum;

[0011] The second acquisition unit is used to acquire, if it is determined from the working condition information that the first washing drum is in the heating process, the first temperature of the first washing drum, the load of clothes and the humidity inside the drum, and the second temperature of the second washing drum.

[0012] The control unit is used to control the second washing drum to heat up based on the first temperature, the load of clothes, the humidity inside the drum, and the second temperature.

[0013] Thirdly, embodiments of this application also provide a washing machine, including a memory storing multiple instructions; a processor loads instructions from the memory to execute the steps of any of the washing machine heating control methods provided in embodiments of this application.

[0014] Fourthly, embodiments of this application also provide a readable storage medium storing multiple computer programs adapted for loading by a processor to execute the steps of any of the washing machine heating control methods provided in embodiments of this application.

[0015] Fifthly, embodiments of this application also provide a computer program product, including multiple computer programs, which, when executed by a processor, implement the steps in any of the washing machine heating control methods provided in embodiments of this application.

[0016] The scheme adopted in the application embodiment obtains the operating condition information of the first washing drum; if it is determined from the operating condition information that the first washing drum is in the heating process, then the first temperature, laundry load, and humidity inside the drum of the first washing drum, and the second temperature of the second washing drum are obtained; based on the first temperature, the laundry load, the humidity inside the drum, and the second temperature, the second washing drum is controlled to heat. By controlling the second washing drum to heat based on the first temperature, laundry load, humidity inside the drum, and the second temperature of the second washing drum while the first washing drum is in the heating process, synchronous heating of the first and second washing drums is achieved, thereby reducing the long running time and energy consumption of the washing machine's dual-drum synchronous heating.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. At the same time, in the description of the embodiments of this application, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] This application provides a washing machine heating control method, apparatus, washing machine, and readable storage medium.

[0025] Specifically, this embodiment will be described from the perspective of a washing machine heating control device, which can be integrated into the washing machine. That is, the washing machine heating control method of this embodiment can be executed by the washing machine.

[0026] The washing machine heating control method provided in this application embodiment can be applied to, for example, twin-drum washing machines.

[0027] The following detailed description is provided in conjunction with the accompanying drawings. In this embodiment, a washing machine is used as the executing entity. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments. Although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown in the accompanying drawings.

[0028] Please refer to Figure 1 The first embodiment of this application proposes a washing machine heating control method, the specific process of which includes the following steps:

[0029] Step 101: Obtain the operating condition information of the first washing drum;

[0030] Step 102: If it is determined from the working condition information that the first washing drum is in the heating process, then obtain the first temperature, clothing load and humidity inside the first washing drum, and the second temperature of the second washing drum.

[0031] Step 103: Based on the first temperature, the load of clothes, the humidity inside the drum, and the second temperature, control the second washing drum to heat up.

[0032] In this embodiment, when the first and second washing drums of the washing machine need to be heated synchronously, the washing machine first heats the first washing drum according to the heating command and obtains the operating condition information of the first washing drum. If it is determined from the operating condition information that the first washing drum is in the heating process, the first temperature, clothing load and humidity inside the drum of the first washing drum, and the second temperature of the second washing drum are obtained. Based on the first temperature, clothing load, humidity inside the drum and the second temperature, it is determined whether the second washing drum can be controlled to heat. If it is determined that the second washing drum can be controlled to heat, the second washing drum is controlled to heat.

[0033] It should be noted that heating includes water heating or drying heating. During the heating of the first washing drum, heating the second washing drum at an appropriate time can ensure that the second washing drum is heated simultaneously while the first washing drum is being heated. This improves and reduces the long running time and energy consumption of the washing machine's dual-drum synchronous heating.

[0034] In this embodiment, the washing machine acquires the operating condition information of the first washing drum. If it is determined from the operating condition information that the first washing drum is in the heating process, it acquires the first temperature, laundry load, and humidity inside the drum of the first washing drum, as well as the second temperature of the second washing drum. Based on the first temperature, laundry load, humidity inside the drum, and second temperature, it controls the second washing drum to heat up. By controlling the second washing drum to heat up based on the first temperature, laundry load, humidity inside the drum, and second temperature of the second washing drum while the first washing drum is in the heating process, synchronous heating of the first and second washing drums is achieved, thereby reducing the long running time and energy consumption of the washing machine's dual-drum synchronous heating.

[0035] Specifically, the following provides a detailed explanation of each step:

[0036] Step 101: Obtain the operating condition information of the first washing drum;

[0037] In this step, when the washing machine receives a command to heat the first washing drum but the second washing drum is not heating, it first controls the first washing drum to heat. When it receives a command to heat the second washing drum, it acquires the operating status information of the first washing drum to determine whether the first washing drum is in the heating process. Heating includes water heating or drying heating.

[0038] It should be noted that when the first washing drum begins drying and heating, the motor performs weighing and eccentricity detection to achieve drying timing operation. The fan of the first washing drum continues to run, and the motor rotates at low speed. The initial temperature of the first washing drum (the actual temperature at the air outlet) is usually room temperature, approximately 20℃ to 30℃. At this time, the washing machine will control the first washing drum to continue heating until the initial temperature of the first washing drum reaches the preset maximum temperature. This process is the heating process of the first washing drum.

[0039] When the temperature of the first washing drum reaches the preset maximum temperature, the washing machine will control the first washing drum to stop heating, so that the temperature of the first washing drum gradually cools down to the preset minimum temperature. This process is called the cooling process of the first washing drum.

[0040] The heating of the first and second washing drums by the washing machine is as described above. Therefore, it is necessary to obtain the operating status information of the first washing drum to determine whether the first washing drum is in the heating process, and further determine whether the second washing drum can be controlled to heat when the first washing drum is in the heating process.

[0041] Step 102: If it is determined from the working condition information that the first washing drum is in the heating process, then obtain the first temperature, clothing load and humidity inside the first washing drum, and the second temperature of the second washing drum.

[0042] In this step, if the washing machine determines that the first washing drum is in the heating process based on the operating condition information, it acquires the first temperature, the load of clothes, and the humidity inside the drum of the first washing drum, as well as the second temperature of the second washing drum. Specifically, when the first washing drum is in the drying heating process, the acquired first temperature is the actual temperature of the air outlet of the first washing drum; when the second washing drum needs to be dried and heated, the second temperature is the actual temperature of the air outlet of the second washing drum; when the second washing drum needs to be heated, the second temperature is the actual water temperature inside the second washing drum. When the first washing drum is in the water heating process, the acquired first temperature is the actual water temperature inside the first washing drum; when the second washing drum needs to be dried and heated, the second temperature is the actual temperature of the air outlet of the second washing drum; when the second washing drum needs to be heated, the second temperature is the actual water temperature inside the second washing drum.

[0043] Step 103: Based on the first temperature, the load of clothes, the humidity inside the drum, and the second temperature, control the second washing drum to heat up.

[0044] In this step, the washing machine determines the remaining heating power based on the first temperature, the load of clothes, and the humidity inside the drum. Then, based on the first temperature, the second temperature, and the remaining heating power, it determines whether it can currently control the second washing drum to heat. If it determines that it can control the second washing drum to heat, it controls the second washing drum to heat. It can be understood that the remaining heating power is the difference between the washing machine's preset total heating power and the first heating power of the first washing drum during the heating process. The first heating power of the first washing drum during the heating process needs to be calculated based on the first temperature, the load of clothes, and the humidity inside the drum.

[0045] Specifically, step 103 includes:

[0046] Step 1031: Determine the remaining heating power based on the first temperature, the clothing load, and the humidity inside the drum;

[0047] In this step, the washing machine calculates the first heating power of the first washing drum based on the first temperature of the first washing drum, the load of clothes and the humidity inside the drum, and then calculates the remaining heating power based on the preset total heating power and the first heating power.

[0048] Further, step 1031 includes:

[0049] Step 10311: If the heating process of the first washing drum is drying heating, then the first heating power of the first washing drum is determined according to the first temperature, the load of clothes and the humidity inside the drum.

[0050] In this step, when the washing machine calculates the first heating power of the first washing drum, it first determines whether the heating process of the first washing drum is drying heating. If the heating process of the first washing drum is drying heating, the first heating power of the first washing drum is determined based on the first temperature, the load of clothes, and the humidity inside the drum. Specifically, the formula for calculating the first heating power of the first washing drum for drying heating is: P = (M*H) + (K*Delta T), where P is the first heating power, M is the load of clothes, H is the energy required for humidity control inside the drum, K is the energy required for temperature control, Delta T is the temperature difference between the first temperature and the target temperature of the first washing drum, the energy required for humidity control inside the drum can be determined by referring to a pre-set table of humidity and energy relationship inside the drum, and the energy required for temperature control can be determined by referring to a pre-set table of temperature and energy relationship.

[0051] Step 10312: If the heating process of the first washing drum is water heating, then the first heating power of the first washing drum is determined according to the first temperature, the load of clothes, the humidity inside the drum and the specific heat capacity of water.

[0052] In this step, if the washing machine determines that the heating process of the first washing drum is water heating, then the first heating power of the first washing drum is determined based on the first temperature, the load of clothes, the humidity inside the drum, and the specific heat capacity of water. Specifically, the formula for calculating the first heating power of the first washing drum water heating is: P = (M * H * C) + (K * Delta T), where P is the first heating power, M is the load of clothes, H is the energy required for humidity control inside the drum, C is the specific heat capacity of water, K is the energy required for first temperature control, Delta T is the temperature difference between the first temperature and the target temperature of the first washing drum, the energy required for humidity control inside the drum can be determined by referring to a pre-set table of humidity and energy relationship inside the drum, and the energy required for first temperature control can be determined by referring to a pre-set table of first temperature and energy relationship.

[0053] Step 10313: Determine the remaining heating power based on the preset total heating power and the first heating power.

[0054] In this step, the washing machine calculates the difference between the preset total heating power and the first heating power, and this difference is the remaining heating power.

[0055] Step 1032: Compare the first temperature with the first temperature threshold, and compare the second temperature with the second temperature threshold;

[0056] In this step, the washing machine compares the first temperature with a first temperature threshold and the second temperature with a second temperature threshold.

[0057] Step 1033: If the first temperature is less than the first temperature threshold and the second temperature is less than the second temperature threshold, then control the second washing drum to heat according to the remaining heating power;

[0058] In this step, if the washing machine determines that the first temperature is less than a first temperature threshold and the second temperature is less than a second temperature threshold, it controls the second washing drum to heat up based on the remaining heating power. Further, if the washing machine determines that the first temperature is less than the first temperature threshold and the second temperature is not less than the second temperature threshold, it does not need to heat the second washing drum.

[0059] Further, step 1033 includes:

[0060] Step 10331: Compare the remaining heating power with the first power threshold and the second power threshold respectively, wherein the first power threshold is less than the second power threshold;

[0061] Step 10332: If the remaining heating power is greater than the second power threshold, then control the heater main function of the second washing drum to heat;

[0062] Step 10333: If the remaining heating power is greater than the first power threshold and less than the second power threshold, then control the heater auxiliary function of the second washing drum to heat.

[0063] In steps 10331 to 10333, after determining the remaining heating power, the washing machine compares the remaining heating power with a first power threshold and a second power threshold, respectively. The first power threshold and the second power threshold are preset, and the first power threshold is less than the second power threshold. The first power threshold represents the peak power when the auxiliary function of the heater of the second washing drum is heating, and the second power threshold represents the peak power when the main function of the heater of the second washing drum is heating. If the washing machine determines that the remaining heating power is greater than the second power threshold, it means that the current remaining power can meet the heating needs of the main function of the heater of the second washing drum, and the main function of the heater of the second washing drum is controlled to heat. If the washing machine determines that the remaining heating power is greater than the first power threshold and less than the second power threshold, it means that the current remaining power can only meet the heating needs of the auxiliary function of the heater of the second washing drum, and the auxiliary function of the heater of the second washing drum is controlled to heat. If the washing machine determines that the remaining heating power is less than the first power threshold, it means that the current remaining power cannot meet the heating needs of the auxiliary function of the heater of the second washing drum, and the second washing drum is not controlled to heat.

[0064] Step 1034: If the first temperature is not less than the first temperature threshold and the second temperature is less than the second temperature threshold, then according to the remaining heating power, control the first washing drum and the second washing drum to heat simultaneously, or control the first washing drum to stop heating and control the second washing drum to heat.

[0065] In this step, if the washing machine determines that the first temperature is not less than the first temperature threshold and the second temperature is less than the second temperature threshold, it controls the first washing drum and the second washing drum to heat simultaneously according to the remaining heating power, or controls the first washing drum to stop heating and controls the second washing drum to heat.

[0066] Further, step 1034 includes:

[0067] Step 10341: Compare the remaining heating power with the third power threshold and the fourth power threshold respectively, wherein the third power threshold is less than the fourth power threshold;

[0068] Step 10342: If the remaining heating power is greater than the fourth power threshold, then control the heater auxiliary function of the first washing drum and the heater main function of the second washing drum to heat simultaneously.

[0069] Step 10343: If the remaining heating power is greater than the third power threshold and less than the fourth power threshold, then control the heater auxiliary function of the first washing tub and the heater auxiliary function of the second washing tub to heat simultaneously.

[0070] Step 10344: If the remaining heating power is less than the third power threshold, then control the first washing drum to stop heating and control the heater of the second washing drum to start heating.

[0071] In steps 10341 to 10344, the washing machine compares the remaining heating power with a third power threshold and a fourth power threshold, respectively. The third power threshold is less than the fourth power threshold. The third power threshold is the peak power when the auxiliary heating function of the first washing drum and the auxiliary heating function of the second washing drum are used simultaneously for heating. The fourth power threshold is the peak power when the auxiliary heating function of the first washing drum and the main heating function of the second washing drum are used simultaneously for heating. If the washing machine determines that the remaining heating power is greater than the fourth power threshold, it means that the current remaining power can meet the requirements of the auxiliary heating function of the first washing drum and the main heating function of the second washing drum for simultaneous heating, and controls the first washing drum to heat up. The auxiliary heater function of the first washing drum and the main heater function of the second washing drum are used for heating simultaneously. If the washing machine determines that the remaining heating power is greater than the third power threshold and less than the fourth power threshold, it means that the current remaining power can only meet the heating of the auxiliary heater function of the first washing drum and the main heater function of the second washing drum simultaneously. If the washing machine determines that the remaining heating power is less than the third power threshold, it means that the current remaining power can only meet the heating of the auxiliary heater function of the second washing drum. It controls the first washing drum to stop heating and controls the auxiliary heater function of the second washing drum to continue heating.

[0072] It is understandable that when the first temperature of the first washing drum is not less than the first temperature threshold, it means that the first temperature of the first washing drum has met certain drying or water heating conditions. Therefore, when the remaining power meets the conditions and the second washing drum needs to be heated, the first washing drum only needs to maintain the heating of the heater auxiliary function.

[0073] Furthermore, after step 103, the following steps are included:

[0074] Step a: Obtain the first cumulative heating time of the first washing drum, and compare the first cumulative heating time with the first target heating time;

[0075] Step b: If the first cumulative heating time is not less than the first target heating time, then control the first washing drum to stop heating and control the heater main function of the second washing drum to start heating.

[0076] Step c, until the second cumulative heating time of the second washing drum is not less than the second target heating time, control the second washing drum to stop heating.

[0077] In steps a to c, after each cycle of heating and cooling in the first washing drum, the washing machine acquires the first cumulative heating time of the first washing drum and compares it with the first target heating time. If the first cumulative heating time is less than the first target heating time, the washing machine continues to control the first washing drum to heat, and during the heating process of the first washing drum, it controls the main function of the heater of the second washing drum to heat. If the first cumulative heating time is not less than the first target heating time, the washing machine stops heating in the first washing drum and controls the main function of the heater of the second washing drum to heat. Similarly, after each cycle of heating and cooling in the second washing drum, the washing machine acquires the second cumulative heating time of the second washing drum. If the second cumulative heating time is less than the second target heating time, the washing machine continues to control the second washing drum to heat. If the second cumulative heating time is not less than the second target heating time, the washing machine stops heating in the second washing drum.

[0078] In this embodiment, the washing machine acquires the operating condition information of the first washing drum. If the operating condition information determines that the first washing drum is in the heating process, it acquires the first temperature, laundry load, and humidity inside the drum of the first washing drum, as well as the second temperature of the second washing drum. Based on the first temperature, laundry load, humidity inside the drum, and second temperature, it controls the second washing drum to heat up. By controlling the second washing drum to heat up based on the first temperature, laundry load, humidity inside the drum, and second temperature of the second washing drum while the first washing drum is in the heating process, synchronous heating of the first and second washing drums is achieved, thereby reducing the long running time and energy consumption of the washing machine's dual-drum synchronous heating.

[0079] Further, refer to Figure 2 The second embodiment of this application is proposed. The difference between the second embodiment and the first embodiment is that, after obtaining the operating condition information of the first washing drum, it further includes:

[0080] Step d: If it is determined from the operating condition information that the first washing drum is in the cooling process, then obtain the second temperature of the second washing drum;

[0081] Step e: If the second temperature is less than the second temperature threshold, then control the heater main function and heater auxiliary function of the second washing drum to heat simultaneously.

[0082] In this embodiment, after the washing machine obtains the operating condition information of the first washing drum, if it determines that the first washing drum is in a cooling process, that is, in the process of cooling from a preset maximum temperature to a preset minimum temperature, then it obtains the second temperature of the second washing drum. If it determines that the second temperature is less than the second temperature threshold, it indicates that the second washing drum needs to be heated, and then it controls the main heater function and auxiliary heater function of the second washing drum to heat simultaneously. It can be understood that the second temperature threshold is the preset minimum temperature of the second washing drum. When the first washing drum is in a cooling process, both the main heater function and auxiliary heater function of the first washing drum are turned off. At this time, the total heating power can be provided to the second washing drum for heating, so the main heater function and auxiliary heater function of the second washing drum can be controlled to heat simultaneously.

[0083] Furthermore, if it is determined that the second temperature is not less than the second temperature threshold, then the second washing drum is not controlled to heat up.

[0084] In this embodiment, when the washing machine determines that the first washing drum is in the cooling process, it controls the main function and auxiliary function of the heater of the second washing drum to heat simultaneously according to the second temperature of the second washing drum. This allows the second washing drum to heat when the first washing drum stops heating, thereby reducing the long running time and energy consumption of the washing machine's dual-drum synchronous heating.

[0085] In specific implementation, optionally, the washing machine determines that the first washing drum is in the drying and heating process, and only obtains the first temperature of the first washing drum and the second temperature of the second washing drum. When the first temperature is less than the preset minimum drying temperature, the first washing drum continues to be in the heating state.

[0086] If the second washing drum's water heating requirement is activated, and the second temperature is lower than the preset minimum water heating temperature, it indicates that the second washing drum urgently needs water heating. The auxiliary function of the first washing drum's drying heater is deactivated, and only the main function of the first washing drum's drying heater is activated. The main or auxiliary function of the second washing drum's drying heater is also activated to heat water in the second washing drum. If the second washing drum's water heating requirement is not activated, or if the water heating requirement is activated but the second temperature is not lower than the preset minimum water heating temperature, it indicates that the second washing drum currently does not require water heating. The auxiliary and main functions of the first washing drum's drying heater remain activated to continue drying and heating the first washing drum.

[0087] If the second washing drum's drying and heating requirement is activated, and the second temperature is lower than the preset minimum drying and heating temperature, it indicates that the second washing drum urgently needs drying and heating. The auxiliary function of the first washing drum's drying heater is turned off, and only the main function of the drying heater is activated. The main or auxiliary function of the second washing drum's drying heater is also activated to dry and heat the second washing drum. If the second washing drum's drying and heating requirement is not activated, or if the drying and heating requirement is activated but the second temperature is not lower than the preset minimum drying and heating temperature, it indicates that the second washing drum currently does not need drying and heating. The auxiliary and main functions of the first washing drum's drying heater remain activated to continue drying and heating the first washing drum.

[0088] When the first temperature is not lower than the preset minimum drying temperature, as long as the second washing drum has a water heating requirement or a drying heating requirement, the main and auxiliary functions of the drying heater of the first washing drum will be immediately turned off, and the main or auxiliary function of the drying heater of the second washing drum will be turned on to dry and heat the second washing drum.

[0089] Furthermore, the washing machine determines that the first washing drum is in the water heating process, and uses the same logic to control whether the second washing drum performs drying heating or water heating, which will not be elaborated here.

[0090] Furthermore, after each cycle of heating and cooling in the first or second washing drum, it is determined whether the current drying time has been used up. If the time has been used up, the main and auxiliary functions of the drying heater in the first or second washing drum are turned off, the motor of the first or second washing drum performs a shaking operation, and when the temperature inside the first or second washing drum is lower than the safe temperature threshold, the motor and fan of the first or second washing drum are turned off, and the drying stage ends.

[0091] Furthermore, after each cycle of heating and cooling in the first or second washing drum, it is determined whether the current water heating time has been used up. If the time has been used up, the main and auxiliary functions of the water heater in the first or second washing drum are turned off, the motor of the first or second washing drum performs a shaking operation, and the water heating stage ends.

[0092] Further, refer to Figure 3This invention also provides a synchronous water heating and drying heating control circuit. H11, H12, H21, H22, H31, H32, H41, and H42 represent the main function, auxiliary function, main function, and auxiliary function of the first washing drum drying heater, the second washing drum drying heater, the first washing drum water heater, the first washing drum water heater, the second washing drum water heater, and the second washing drum water heater, respectively. H11, H12, H21, H22, H31, H32, H41, and H42 switch between the main and auxiliary functions of the heater via relays K11, K12, K21, K22, K31, K32, K41, and K42. For example, if K11 is closed and K12 is open, both the main and auxiliary functions of the A-drying heater are activated. If K11 is closed and K12 is closed, the main function of the A-drying heater is activated, and the auxiliary function is deactivated. For example, if K11 is disconnected, both the main and auxiliary functions of the A-tube drying heater will be disconnected.

[0093] This embodiment also provides a washing machine heating control device, which can be integrated into equipment such as twin-drum washing machines or double-tub washing machines. Figure 4 As shown, the washing machine heating control device may include:

[0094] The first acquisition unit 1001 is used to acquire the operating condition information of the first washing drum;

[0095] The second acquisition unit 1002 is used to acquire the first temperature, clothing load and humidity inside the first washing drum, and the second temperature of the second washing drum if it is determined from the working condition information that the first washing drum is in the heating process.

[0096] The control unit 1003 is used to control the second washing drum to heat up based on the first temperature, the load of clothes, the humidity inside the drum and the second temperature.

[0097] In an optional example, the control unit is also used for:

[0098] The remaining heating power is determined based on the first temperature, the clothing load, and the humidity inside the drum.

[0099] The first temperature is compared with the first temperature threshold, and the second temperature is compared with the second temperature threshold;

[0100] If the first temperature is less than the first temperature threshold and the second temperature is less than the second temperature threshold, then the second washing drum is controlled to heat according to the remaining heating power;

[0101] If the first temperature is not less than the first temperature threshold and the second temperature is less than the second temperature threshold, then based on the remaining heating power, the first washing drum and the second washing drum are controlled to heat simultaneously, or the first washing drum is controlled to stop heating and the second washing drum is controlled to heat.

[0102] In an optional example, the control unit is also used for:

[0103] If the heating process of the first washing drum is drying heating, then the first heating power of the first washing drum is determined according to the first temperature, the load of clothes and the humidity inside the drum;

[0104] If the heating process of the first washing drum is water heating, then the first heating power of the first washing drum is determined based on the first temperature, the load of clothes, the humidity inside the drum, and the specific heat capacity of water.

[0105] The remaining heating power is determined based on the preset total heating power and the first heating power.

[0106] In an optional example, the control unit is also used for:

[0107] The remaining heating power is compared with a first power threshold and a second power threshold, respectively, and the first power threshold is less than the second power threshold;

[0108] If the remaining heating power is greater than the second power threshold, then the heater of the second washing drum is controlled to perform heating.

[0109] If the remaining heating power is greater than the first power threshold and less than the second power threshold, then the heater auxiliary function of the second washing drum is controlled to heat.

[0110] In an optional example, the control unit is also used for:

[0111] The remaining heating power is compared with the third power threshold and the fourth power threshold, respectively, and the third power threshold is less than the fourth power threshold;

[0112] If the remaining heating power is greater than the fourth power threshold, then the heater auxiliary function of the first washing drum and the heater main function of the second washing drum are controlled to heat simultaneously.

[0113] If the remaining heating power is greater than the third power threshold and less than the fourth power threshold, then the heater auxiliary function of the first washing tub and the heater auxiliary function of the second washing tub are controlled to heat simultaneously.

[0114] If the remaining heating power is less than the third power threshold, the first washing drum is controlled to stop heating, and the heater of the second washing drum is controlled to start heating.

[0115] In an optional example, the control unit is also used for:

[0116] If it is determined from the operating condition information that the first washing drum is in the cooling process, then the second temperature of the second washing drum is obtained;

[0117] If the second temperature is less than the second temperature threshold, then the main heater function and the auxiliary heater function of the second washing drum are controlled to heat simultaneously.

[0118] In an optional example, the control unit is also used for:

[0119] Obtain the first cumulative heating time of the first washing drum, and compare the first cumulative heating time with the first target heating time;

[0120] If the first cumulative heating time is not less than the first target heating time, then control the first washing drum to stop heating and control the heater of the second washing drum to start heating.

[0121] The second washing drum is controlled to stop heating until the second cumulative heating time is not less than the second target heating time.

[0122] The solution in this embodiment obtains the operating condition information of the first washing drum. If it is determined from the operating condition information that the first washing drum is in the heating process, then the first temperature, laundry load, and humidity inside the drum of the first washing drum, as well as the second temperature of the second washing drum, are obtained. Based on the first temperature, laundry load, humidity inside the drum, and second temperature, the second washing drum is controlled to heat. By controlling the second washing drum to heat based on the first temperature, laundry load, humidity inside the drum, and second temperature of the second washing drum while the first washing drum is in the heating process, synchronous heating of the first and second washing drums is achieved, thereby reducing the long running time and energy consumption of the washing machine's dual-drum synchronous heating.

Those skilled in the art will understand that the washing machine structure shown in the figure does not constitute a limitation on the washing machine, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0124] The processor 1101 is the control center of the washing machine 1100. It connects to various parts of the washing machine 1100 via various interfaces and lines. By running or loading software programs and / or units stored in the memory 1102, and by calling data stored in the memory 1102, it executes various functions of the washing machine 1100 and processes data, thereby providing overall monitoring of the washing machine 1100. The processor 1101 can be a CPU, GPU, network processor (NP), etc., and can implement or execute the methods, steps, and logic diagrams disclosed in the embodiments of this application.

[0125] In this embodiment of the application, the processor 1101 in the washing machine 1100 will load the instructions corresponding to the processes of one or more applications into the memory 1102 according to the following steps, and the processor 1101 will run the applications stored in the memory 1102 to execute any of the washing machine heating control methods provided in this embodiment of the application.

Those skilled in the art will understand that... Figure 5 The washing machine structure shown does not constitute a limitation on the washing machine and may include more or fewer parts than shown, or combine certain parts, or have different arrangements of parts.

[0127] The touch display screen 1103 can be used to display a graphical user interface (GUI) and receive operation commands generated by the user interacting with the GUI. The touch display screen 1103 may include a display panel and a touch panel. The display panel can be used to display information input by the user or information provided to the user, as well as various GUIs of the washing machine. These GUIs can be composed of graphics, text, icons, video, and any combination thereof. Optionally, the display panel can be configured using a liquid crystal display (LCD), organic light-emitting diode (OLED), or other similar technologies. The touch panel can be used to collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near the touch panel), and generate corresponding operation commands, which then execute the corresponding program. Optionally, the touch panel may include a touch detection device and a touch controller. The touch detection device detects the user's touch location and the signal generated by the touch operation, transmitting the signal to the touch controller. The touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to the processor 1101. It can also receive and execute commands from the processor 1101. The touch panel can cover the display panel. When the touch panel detects a touch operation on or near it, it transmits the information to the processor 1101 to determine the type of touch event. Subsequently, the processor 1101 provides corresponding visual output on the display panel based on the type of touch event. In this embodiment, the touch panel and the display panel can be integrated into the touch display screen 1103 to achieve input and output functions. However, in some embodiments, the touch panel and the touch display screen 1103 can be implemented as two independent components to achieve input and output functions.

Audio circuit 1105 can convert received audio data into electrical signals and transmit them to the speaker, where the speaker converts them into sound signals for output. Conversely, the microphone converts collected sound signals into electrical signals, which are then received by audio circuit 1105, converted back into audio data, and processed by processor 1101. The audio data is then transmitted via radio frequency circuit 1104 to, for example, another washing machine, or output to memory 1102 for further processing. Audio circuit 1105 may also include an earphone jack to provide communication between external headphones and the washing machine.
