[0020] Reference Attachment Figure 1 This embodiment provides a cleaning method for foaming pollutants, which is applied to a cleaning machine. The cleaning machine includes a cleaning pump. The method includes: S1: During the cleaning process of the cleaning machine, the working status information of the cleaning machine is monitored, and the working status information includes the operating parameters of the cleaning pump and the foam contamination coefficient inside the cleaning machine; Specifically, the foam fouling coefficient represents the degree of foam fouling in the cleaning machine, and the operating parameters of the cleaning pump represent the operating state of the motor power of the cleaning pump.

[0021] S2: When the operating parameters and the foam pollution coefficient meet the preset foaming pollutant detection conditions, the cleaning machine is controlled to operate in the foaming pollutant cleaning mode; Specifically, the preset foaming contaminant detection conditions can be used to indicate foaming contaminant information within the cleaning machine, and the foaming contaminant information is used to indicate whether foaming contaminants are present within the cleaning machine. In the present invention, foaming contaminants can refer to food residues such as meat and starch that easily foam during cleaning, or to substances that easily foam, such as steamed egg liquid. This application does not specifically limit the foaming contaminants; it only requires that the cleaning machine generate foam during the cleaning process.

[0022] In some embodiments, the operating parameters include actual motor operating power of the cleaning pump and operating time of the cleaning pump, and the foam turbidity coefficient includes a transparency fluctuation index, which is used to indicate the standard deviation of turbidity values measured by the cleaning machine; The preset foaming pollutant detection condition means that the actual motor operating power of the cleaning pump is less than or equal to the preset motor power average, and the difference between the actual motor operating power of the cleaning pump and the preset motor power average is greater than the first preset motor power value, and the running time of the cleaning pump is greater than the first preset running time, and the transparency fluctuation index is greater than the preset transparency fluctuation index average. The preset transparency fluctuation index average is used to indicate the average value of the transparency fluctuation index measured after running the current cleaning mode multiple times.

[0023] Specifically, the preset motor power average value refers to the average value of the actual operating motor power of the cleaning pump after running the current cleaning mode multiple times.

[0024] Specifically, the actual motor operating power of a cleaning pump refers to the output power of the cleaning pump under actual operating conditions. The motor power of a cleaning pump is generally divided into actual operating motor power and rated operating motor power. Under ideal circumstances, the actual operating motor power and the rated operating motor power are equal. However, due to factors such as load changes, efficiency loss, and working environment, the actual operating motor power is usually less than the rated operating power.

[0025] Specifically, the first preset motor power value is 10 W-30 W. Preferably, the first preset motor power value is 20 W.

[0026] Specifically, the first preset running time is 5s-20s. Preferably, the first preset running time is 10s.

[0027] In this embodiment, by judging the relationship between the actual motor operating power of the cleaning pump and the preset motor power average, the relationship between the operating time of the cleaning pump and the first preset operating time, and the relationship between the transparency fluctuation index and the preset transparency fluctuation index average, it is possible to accurately judge whether there are foaming pollutants inside the cleaning machine, and then run a specific foaming pollutant cleaning mode to remove foaming pollutants, thereby improving cleanliness.

[0028] In some embodiments, if the operating parameters and foam contamination coefficient of the cleaning pump do not meet the preset foaming contaminant detection conditions, the cleaning machine is controlled to switch to a preset cleaning mode.

[0029] Specifically, the preset cleaning mode refers to the cleaning mode selected by the cleaning machine after it is currently started. The preset cleaning mode can be a strong cleaning mode, a daily cleaning mode, an energy-saving cleaning mode, an intelligent cleaning mode, a quick cleaning mode, etc., which is not specifically limited in this application.

[0030] Specifically, if the operating parameters and foam pollution coefficient of the cleaning pump do not meet the preset foaming pollutant detection conditions, the cleaning machine is controlled to switch to the preset cleaning mode, including: If the actual motor operating power of the cleaning pump is greater than the preset motor power average, and the difference between the actual motor operating power of the cleaning pump and the preset motor power average is less than or equal to the first preset motor power value, and the running time of the cleaning pump is less than or equal to the first preset running time, and the transparency fluctuation index is less than or equal to the preset transparency fluctuation index average, control the cleaning machine to switch to the preset cleaning mode operation, control the cleaning machine to switch to the preset cleaning mode operation.

[0031] In this embodiment, if the operating parameters and the foam turbidity coefficient do not meet the preset foaming pollutant detection conditions, it indicates that there are no foaming pollutants inside the washing machine, that is, the preset cleaning mode can be used for operation, avoiding the problem of high energy consumption caused by using a strong cleaning mode to clean tableware without foaming pollutants, and at the same time simplifying the process.

[0032] Specifically, the specific process of determining whether the operating parameters and foam pollution coefficient meet the preset foaming pollutant detection conditions includes: S21: Is the actual operating motor power of the cleaning pump less than or equal to the preset motor power average value, is the difference between the actual operating motor power of the cleaning pump and the preset motor power average value greater than the first preset motor power value, is the operating time of the cleaning pump greater than the first preset operating time, and is the transparency fluctuation index greater than the preset transparency fluctuation index average value? If so, execute step S22; if not, execute step S23; S22: Control the cleaning machine to run a foaming pollutant cleaning mode; S23: Control the cleaning machine to perform cleaning according to a preset cleaning mode.

[0033] In some embodiments, the operating parameters include the rated motor operating power of the cleaning pump; During the operation of the foaming contaminant cleaning mode, the rated motor operating power of the cleaning pump needs to exceed the preset rated motor operating power in stages.

[0034] Specifically, the preset rated motor operating power is used to indicate the motor power threshold at which the cleaning pump can operate continuously without overloading. To ensure the lifespan of the cleaning pump, the factory typically sets a maximum motor power setting for the cleaning pump to ensure continuous operation without overloading. This is known as the preset rated motor operating power. This prevents problems such as overheating of the motor coil or excessive load, which could shorten the lifespan of the cleaning pump.

[0035] During the operation of the foaming pollutant cleaning mode of the present invention, the rated motor operating power of the cleaning pump is set to periodically exceed the preset rated motor operating power, thereby greatly increasing the cleaning pressure of the cleaning pump within a period of time, so that the foaming pollutants can be quickly cleaned, which not only saves cleaning time but also improves cleanliness.

[0036] In some embodiments, the cleaning pump includes a motor having a winding disposed thereon, and the operating parameters of the cleaning pump include a winding temperature of the motor and an operating time when the rated motor operating power of the cleaning pump exceeds a preset rated motor operating power; During the operation of the foaming contaminant cleaning mode, when the winding temperature reaches a preset winding temperature, the rated motor operating power of the cleaning pump is controlled to decrease to the preset rated motor power and continue to work for a preset time. The preset winding temperature is used to indicate the temperature threshold that the motor winding is allowed to reach under safe operating conditions; Alternatively, during the operation of the foaming pollutant cleaning mode, when the winding temperature has not reached the preset winding temperature, if the rated motor operating power of the cleaning pump exceeds the preset rated motor operating power for a period of time that reaches a preset first operating time, the rated motor operating power of the cleaning machine is controlled to decrease to the preset rated motor power and continue to operate for the preset time; The preset first working time is used to indicate the time required for the winding temperature generated when the rated motor operating power of the cleaning pump exceeds the preset rated motor operating power to reach the preset winding temperature when the cleaning machine is under different external temperatures.

[0037] Specifically, during the operation of the foaming contaminant cleaning mode, when the winding temperature has not reached the preset winding temperature and the rated motor operating power of the cleaning pump has not reached the preset first working time when the working time exceeds the preset rated motor operating power, the cleaning machine is controlled to continue to operate when it exceeds the preset rated motor operating power until the working time reaches the preset first working time, and the rated motor operating power of the cleaning machine is controlled to drop to the preset rated motor power and continue to operate for the preset time.

[0038] In this embodiment, since the rated motor operating power of the cleaning pump exceeds the preset rated motor operating power, it may cause winding overheating, thereby reducing the service life of the cleaning pump, and sometimes even causing damage to the cleaning pump. In order to greatly improve the cleaning pressure of the cleaning pump while avoiding damage to the cleaning pump, the present invention monitors the relationship between the winding temperature of the cleaning pump and the preset winding temperature in real time, as well as the relationship between the working time of the cleaning pump when the rated motor operating power exceeds the preset rated motor operating power and the preset first working time. This avoids the problem of the cleaning pump's service life being reduced due to the cleaning pump's working time being too long when the rated motor operating power exceeds the preset rated motor operating power. At the same time, it protects the winding material of the motor and improves the cleanliness.

[0039] In some embodiments, the operating status information includes a resistance temperature coefficient of a material used in the winding, a starting temperature of the winding, a starting resistance of the winding, and an operating resistance of the winding. The method further includes: The winding temperature of the cleaning pump is determined based on the resistance temperature coefficient of the winding material, the starting temperature of the winding, the starting resistance of the winding and the running resistance of the winding. The winding temperature of the cleaning pump is positively correlated with the running resistance and the starting temperature of the winding, and negatively correlated with the starting resistance of the winding. The starting temperature of the winding is used to indicate the temperature of the winding measured before the motor starts; The starting resistance of the winding is used to indicate the resistance of the winding measured at the starting temperature; The running resistance of the winding is used to indicate the resistance of the winding measured when the rated motor running power of the cleaning pump exceeds the preset rated motor running power.

[0040] Specifically, when the rated motor operating power of the cleaning pump exceeds the preset rated motor operating power, the operating resistance of the winding changes with the change of the working time of the cleaning pump.

[0041] Specifically, the material used for the winding can be copper, aluminum, insulating material, etc., and this application does not make any specific restrictions here.

[0042] Exemplarily, the winding temperature of the cleaning pump is obtained by the following formula: T = Tref + (RT / Rref −1) / α; in, Tref is the starting temperature of the winding, Rref is the starting resistance of the winding, RT is the running resistance of the winding, and α is the resistance temperature coefficient of the material used in the winding.

[0043] In this embodiment, by real-time testing of the winding temperature of the cleaning pump when the rated motor operating power exceeds the preset rated motor operating power, the problem of damage to the cleaning pump due to excessive winding temperature is avoided, thereby ensuring the service life of the cleaning pump.

[0044] In some embodiments, the working status information includes a cleaning temperature of the cleaning machine, an external temperature, and safety configuration information, wherein the safety configuration information includes multiple preset cleaning temperatures and thermal protection times corresponding to the multiple preset cleaning temperatures. The method further includes: Based on the monitored cleaning temperature, the thermal protection time is matched with the safety configuration information to determine the thermal protection time of the cleaning machine; determining the preset first operating time based on the thermal protection time, the external temperature, and the resistance temperature coefficient of the material used for the winding; The thermal protection time is used to indicate the time required for the winding temperature generated when the rated motor operating power of the cleaning pump exceeds the preset rated motor operating power to reach the preset winding temperature when the cleaning machine is at normal ambient temperature.

[0045] Specifically, the safety configuration information is the thermal protection time corresponding to the monitored cleaning temperature, and the preset cleaning temperature corresponding to the safety configuration information matches the monitored cleaning temperature. In this embodiment, multiple preset cleaning temperatures and their corresponding thermal protection times can be obtained through configuration.

[0046] Exemplarily, the preset first working time is obtained by the following formula: ; ; in, Thermal protection time, To preset the first working time, is the resistance temperature coefficient of the material used in the winding, For example, if the material used for the winding is copper, the temperature coefficient of the material used for the winding is 0.00393 / °C.

[0047] Specifically, Characterizes the degree of influence of temperature changes in the external environment on the thermal protection time, Used to indicate the actual value of the thermal protection time under the influence of temperature changes in the external environment.

[0048] Specifically, the thermal protection time obtained by the cleaning machine varies depending on the cleaning temperature. The thermal protection time has been set when the cleaning machine leaves the factory. For example, the thermal protection time is determined as follows: When the external temperature of the cleaning machine is 25℃, the cleaning temperature of the cleaning machine is 35℃. The rated motor operating power of the cleaning pump is set to exceed the preset rated motor operating power. The time for the winding temperature generated when the rated motor operating power of the cleaning pump exceeds the preset rated motor operating power to reach the preset winding temperature is measured, which is the thermal protection time when the cleaning temperature of the cleaning machine is 35℃. The cleaning temperature of the cleaning machine can be set to 25℃, 45℃, 55℃ and other temperatures. The thermal protection time of the cleaning machine when the cleaning temperature is below 25℃, 45℃ and 55℃ can be measured respectively.

[0049] Since the external temperature of the cleaning machine will affect the preset first working time of the cleaning pump when the rated motor operating power exceeds the preset rated motor operating power, if the external temperature of the cleaning machine is high or low, the preset first working time of the cleaning pump when the rated motor operating power exceeds the preset rated motor operating power will be extended or shortened accordingly. Therefore, different preset operating times need to be set according to different external temperatures, which can greatly improve the cleaning pressure of the cleaning pump while ensuring the service life of the cleaning pump.

[0050] In some embodiments, before controlling the cleaning machine to operate in a foaming contaminant cleaning mode, the method further comprises: controlling the cleaning machine to drain water and then to allow water to flow in; The operating parameters of the cleaning pump include motor operating power information, the motor operating power information includes at least one actual motor operating power value, and the actual motor operating power value represents the actual motor operating power value of the cleaning pump detected after executing a foaming pollutant cleaning mode; The foam turbidity coefficient includes transparency information, which includes at least one transparency value. The transparency value represents the turbidity value inside the cleaning machine detected after executing a foaming contaminant cleaning mode. The fluctuation value of the foam turbidity coefficient is between 0 and 1 NTU, which means that the difference between at least two transparency values is between 0 and 1 NTU. Controlling the cleaning machine to operate the foaming contaminant cleaning mode includes: controlling the rated motor operating power of the cleaning pump to exceed the preset rated motor operating power, and cleaning the cleaning machine when the preset rated motor operating power is exceeded; If at least one monitored actual motor operating power value is greater than or equal to a preset motor power average value and the difference between at least two transparency values is between 0 and 1 NTU, executing the step of controlling the cleaning machine to perform cleaning according to a preset cleaning mode; If at least one monitored actual motor operating power value is less than a preset motor power average or the difference between at least two transparency values is not between 0 and 1 NTU, the steps of controlling the rated motor operating power of the cleaning pump to exceed the preset rated motor operating power and cleaning the cleaning machine when the preset rated motor operating power is exceeded are repeated until at least one actual motor operating power value is greater than or equal to the preset motor power average and the difference between at least two transparency values is between 0 and 1 NTU.

[0051] In this embodiment, by obtaining the actual motor operating power value and transparency value of the cleaning pump, it is possible to determine whether the foaming pollutants in the cleaning machine have been removed after controlling the rated motor operating power of the cleaning pump to exceed the preset rated motor operating power. If not, the steps of controlling the rated motor operating power of the cleaning pump to exceed the preset rated motor operating power for cleaning are repeated, and the actual motor operating power value and transparency value of the cleaning pump are repeatedly obtained to ensure cleanliness.

[0052] Specifically, the specific process of controlling the cleaning machine to operate the foaming contaminant cleaning mode includes: S24: controlling the rated motor operating power of the cleaning pump to exceed the preset rated motor operating power, and cleaning the cleaning machine when the preset rated motor operating power is exceeded, and executing S25; S25: Check whether the winding temperature reaches the preset winding temperature. If so, execute S26; if not, execute S27. S26: Control the rated motor operating power of the cleaning pump to decrease to a preset rated motor power and continue the operation for a preset time, and then execute S28; S27: Whether the working time of the rated motor operating power of the cleaning pump exceeds the preset rated motor operating power reaches the preset first working time, if so, execute step S26, if not, execute step S29; S28: Is the actual motor operating power value greater than or equal to the preset motor power average value? If so, execute step S30; if not, execute step S31; S29: Controlling the cleaning machine to continue operating at a power exceeding the preset rated motor operating power until the operating time reaches a preset first operating time, controlling the rated motor operating power of the cleaning machine to decrease to the preset rated motor power and continue operating for the preset time, and executing step S28; S30: Repeat steps S24-S28 to check whether the difference between the two transparency values is between 0 and 1 NTU. If so, execute S31; if not, execute step S32. S31: executing the step of controlling the cleaning machine to perform cleaning according to a preset cleaning mode; S32: Repeat steps S24-S31.

[0053] S3: If the operating parameter is greater than or equal to the preset motor power average value and the fluctuation value of the foam turbidity coefficient is between 0 and 1 NTU, the cleaning machine is controlled to perform cleaning according to the preset cleaning mode.
