Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a cleaning control method and device for a cleaning machine, and the cleaning machine. Background Art

[0002] Dishwashers, as a tableware washing device, are widely used in restaurants, hotels, homes and other places where various types of tableware are needed to wash tableware in batches and improve the washing efficiency of tableware.

[0003] Existing dishwashers use a cleaning pump to pressurize water, which is then sprayed out from small holes in the spray arm to form a high-pressure water column to flush the dishes to be washed. One of the key cleaning factors is the cleaning pressure of the cleaning pump. To ensure the lifespan and safety of the cleaning pump, the motor of the cleaning pump is generally set with a rated power when it leaves the factory. Due to the limited rated power of the cleaning pump, for difficult-to-clean contaminants such as burnt protein (egg liquid / cheese) and pigment deposits (curry, soy sauce), the cleaning efficiency can only be guaranteed by increasing the cleaning time, which in turn increases user waiting time and energy consumption.

[0004] In summary, for pollutants that are difficult to clean, the cleaning method of the dishwasher in the prior art can only ensure cleanliness by increasing the cleaning time, etc., which increases the user's waiting time and energy consumption. Summary of the Invention

[0020] Reference Attachment Figure 1 This embodiment provides a drainage control method for a cleaning machine, wherein the cleaning machine includes a cleaning pump, and the method includes: S1: During the cleaning process of the cleaning machine, monitor the operating status information of the cleaning machine; Specifically, the operating status information may indicate pollutant information of the cleaning machine during the cleaning process, and the pollutant information is used to indicate whether pollutants exist inside the cleaning machine during the cleaning process.

[0021] S2: If the operating status information indicates that there are pollutants inside the cleaning machine, the cleaning machine is controlled to operate in the pollutant cleaning mode. During the operation in the pollutant cleaning mode, the motor power of the cleaning pump is controlled to reach a first preset power during at least part of the operating period. The first preset power is greater than or equal to the motor power threshold allowed when the cleaning pump is instantaneously overloaded.

[0022] Specifically, in step S2, when the cleaning pump is in a momentary overload, it means that the load power borne by the motor of the cleaning pump exceeds the rated power of the motor. The rated power refers to the second preset power. When the cleaning pump of the cleaning machine leaves the factory, in order to ensure the cleaning life of the cleaning pump, the maximum motor power when the cleaning pump is continuously running without overload is usually set, that is, the rated power, to avoid the problem of overheating of the motor coil or excessive load causing the life of the cleaning pump to be reduced.

[0023] In some embodiments, if the operating status information indicates that no contaminants exist inside the cleaning machine, the cleaning machine is controlled to switch to a preset cleaning mode.

[0024] In some embodiments, the cleaning pump includes a motor having a motor coil, and the operating status information includes a temperature of the motor coil of the cleaning pump and an operating time of the motor of the cleaning pump at a first preset power; During the operation of the pollutant cleaning mode, if the monitored operating status information meets the preset safety conditions, the motor power of the cleaning pump is controlled to drop from the first preset power to the second preset power and continue for the preset time. The preset safety conditions refer to that the running time of the motor power of the cleaning pump at the first preset power reaches the preset running time or the temperature of the motor coil reaches the preset temperature; the preset running time is used to indicate the time required for the temperature of the motor coil generated when the cleaning pump is instantaneously overloaded at different ambient temperatures to reach the preset temperature; the second preset power is used to indicate the motor power threshold value at which the cleaning pump will not be overloaded when it runs continuously; the preset temperature is used to indicate the temperature threshold value allowed by the material used for the motor coil.

[0025] Specifically, the second preset power is used to indicate the motor power threshold at which the cleaning pump does not overload when running continuously. The second preset power here may refer to the rated power of the cleaning pump motor, or the maximum motor power set for the cleaning pump motor at the factory.

[0026] In some embodiments, during operation in the pollutant cleaning mode, if the monitored operating status information meets a preset safety condition, the motor power of the cleaning pump is controlled to decrease from a first preset power to a second preset power and continue for a preset time, wherein the preset safety condition refers to the motor power of the cleaning pump operating at the first preset power for a preset operating time or the temperature of the motor coil reaching a preset temperature; In this embodiment, if the cleaning pump runs for too long at the first preset power, the motor coil will overheat, thereby reducing the service life of the cleaning pump, and in severe cases, the cleaning pump will be damaged. In order to ensure cleanliness and reduce energy consumption while avoiding the above problems, the running time of the cleaning pump at the first preset power and the temperature of the motor coil are monitored, thereby avoiding the problem of damage to the cleaning pump due to excessive running time and overheating of the motor coil. Cleanliness is also ensured, energy consumption is reduced, and cleaning time is shortened.

[0027] In some embodiments, during operation in the pollutant cleaning mode, if the monitored operating status information does not meet a preset safety condition, the motor power of the cleaning pump is controlled to continue operating at a first preset power until the preset safety condition is met.

[0028] The motor power of the cleaning pump is controlled to drop from a first preset power to a second preset power and last for a preset time. The preset safety condition means that the running time of the motor power of the cleaning pump at the first preset power reaches the preset running time or the temperature of the motor coil reaches the preset temperature.

[0029] Specifically, the temperature of the motor coil of the cleaning pump is obtained by the following steps: Obtain the temperature coefficient of the material used in the motor coil, the initial temperature of the motor coil, the initial resistance of the motor coil, and the operating resistance of the motor coil; The temperature of the motor coil of the cleaning pump is determined based on the temperature coefficient of the material used in the motor coil, the initial temperature of the motor coil, the initial resistance of the motor coil and the operating resistance of the motor coil. The initial temperature of the motor coil is used to indicate the temperature of the motor coil measured before the motor is started. The initial resistance of the motor coil is used to indicate the resistance of the motor coil measured at the initial temperature. The operating resistance of the motor coil is used to indicate the resistance of the motor coil measured when the cleaning pump is in a momentary overload.

[0030] Specifically, when the washer pump is in a momentary overload state, the operating resistance of the motor coil changes as the operating time of the washer pump changes.

[0031] Exemplarily, the temperature of the motor coil of the cleaning pump is obtained by the following formula: T = Tref + (RT / Rref −1) / α; in, Tref is the initial temperature of the motor coil, Rref is the initial resistance of the motor coil, RT is the operating resistance of the motor coil, and α is the temperature coefficient of the material used in the motor coil.

[0032] In some embodiments, the preset running time is obtained by the following steps: Obtain the ambient temperature of the cleaning machine, the overheating time threshold, and the temperature coefficient of the material used for the motor coil. The overheating time threshold indicates the time required for the motor coil temperature to reach a preset temperature when the cleaning pump is momentarily overloaded and the cleaning machine is at normal ambient temperature. Based on the ambient temperature of the cleaning machine, the overheating time threshold and the temperature coefficient of the material used in the motor coil, the preset operating time of the cleaning pump at the first preset power is determined, wherein the preset operating time is positively correlated with the ambient temperature of the cleaning machine, the overheating time threshold and the temperature coefficient of the material used in the motor coil, respectively.

[0033] Specifically, the material used for the motor coil can be copper, aluminum, insulating material, etc., and this application does not make any specific restrictions here.

[0034] Since the ambient temperature of the cleaning machine will affect the preset running time of the cleaning pump at the first preset power, if the ambient temperature of the cleaning machine is high or low, the preset running time of the cleaning pump at the first preset power will be extended or shortened accordingly. Therefore, different preset running times need to be set according to different ambient temperatures, which can greatly improve the cleaning pressure of the cleaning pump while ensuring the service life of the cleaning pump.

[0035] Exemplarily, the preset running time is obtained by the following formula: ; ; in, is the overheating time threshold, For the preset running time, is the temperature coefficient of the material used in the motor coil, is the ambient temperature, and the temperature coefficient of the material used in the motor coil is the resistance temperature coefficient of the motor coil; for example, if the material used in the motor coil is copper, the temperature coefficient of the material used in the motor coil is 0.00393 / °C.

[0036] Specifically, the overheating time threshold is determined based on the cleaning temperature of the cleaning machine. Different cleaning temperatures of the cleaning machine will result in different overheating time thresholds. The overheating time threshold is set when the cleaning machine leaves the factory. For example, the process of determining the overheating time threshold is as follows: When the ambient temperature of the cleaning machine is 25°C, the cleaning temperature of the cleaning machine is 35°C. At this time, the motor power of the cleaning pump is increased to the first preset power, and the time it takes for the temperature of the motor coil generated by the motor power of the cleaning pump at the first preset power to reach the preset temperature is measured, which is the overheating time threshold of the cleaning machine when the cleaning temperature is 35°C; the cleaning temperature of the cleaning machine can be set to 25°C, 45°C, 55°C and other temperatures, and the overheating time thresholds of the cleaning machine when the cleaning temperature is below 25°C, 45°C and 55°C can be measured respectively.

[0037] In some embodiments, the operating status information includes cleaning mode selection information received by the cleaning machine after the cleaning machine is currently started. Before controlling the cleaning machine to operate in the contaminant cleaning mode, the method further includes: If the cleaning mode selection information indicates that the triggered cleaning mode is the strong cleaning mode, it is determined that the operating status information indicates that contaminants exist inside the cleaning machine.

[0038] Specifically, the cleaning mode selection information is used to indicate the selected cleaning mode received by the cleaning machine after the current startup. The cleaning mode includes a strong cleaning mode and a non-strong cleaning mode. The difference in cleaning parameters between the strong cleaning mode and the non-strong cleaning mode lies in the different motor power of the cleaning pump, wherein the motor power of the cleaning pump in the strong cleaning mode is greater than the motor power of the cleaning pump in the non-strong cleaning mode.

[0039] In this embodiment, by selecting the strong cleaning mode as the cleaning mode by the user, it can be preliminarily determined that there are difficult-to-clean contaminants on the items to be cleaned in the cleaning machine, thereby simplifying the operation process and shortening the user's waiting time.

[0040] In some embodiments, the operating status information includes a current turbidity value of the cleaning machine. Before controlling the cleaning machine to operate in the contaminant cleaning mode, the method further includes: When the cleaning mode selection information indicates that the triggered cleaning mode is a non-strong cleaning mode, if the current turbidity value is less than the preset turbidity average value and the difference between the current turbidity value and the preset turbidity average value is greater than the preset turbidity initial value, it is determined that the operating status information indicates that there are contaminants inside the cleaning machine; the preset turbidity initial value is used to indicate the turbidity value measured by the cleaning machine when it is initialized, and the preset turbidity average value is used to indicate the average value of the turbidity values measured after running the current cleaning mode multiple times.

[0041] In some embodiments, the operating status information includes a current turbidity value of the cleaning machine. Before controlling the cleaning machine to operate in the contaminant cleaning mode, the method further includes: If the current turbidity value is greater than or equal to the preset turbidity average value or the difference between the current turbidity value and the preset turbidity average value is less than or equal to the preset turbidity initial value, it is determined that the operating status information indicates that there is no contaminant inside the cleaning machine, and the cleaning machine is controlled to operate in the triggered non-strong cleaning mode.

[0042] In this embodiment, by judging that the current turbidity value is less than the preset turbidity average value and the difference between the current turbidity value and the preset turbidity average value is greater than the preset turbidity initial value, it is possible to judge that there are pollutants inside the current cleaning machine that are difficult to clean, thereby avoiding the problem of pollutants inside the cleaning machine causing the cleaning time to be too long and thus increasing energy consumption. In addition, by judging the relationship between the current turbidity value, the preset turbidity average value and the preset turbidity initial value, the accuracy of judging whether there are pollutants inside the cleaning machine that are difficult to clean is improved.

[0043] In some embodiments, before controlling the cleaning machine to operate in the contaminant cleaning mode, the specific process of the method includes: S11: Is the cleaning mode a strong cleaning mode? If so, execute S12; if not, determine that the cleaning mode is a non-strong cleaning mode and execute S13; S12: Determine whether there are pollutants inside the cleaning machine, and control the cleaning machine to operate in a pollutant cleaning mode; S13: Is the current turbidity value less than the preset turbidity average value and the difference between the current turbidity value and the preset turbidity average value greater than the preset turbidity initial value? If so, execute S12; if not, execute S14; S14: Determine that no pollutants exist in the cleaning machine, and control the cleaning machine to operate in a triggered non-strong cleaning mode.

[0044] In some embodiments, the contaminant cleaning mode includes a first contaminant cleaning step and a second contaminant cleaning step, and controlling the cleaning machine to operate in the contaminant cleaning mode includes: Controlling the cleaning machine to run at least one first contaminant cleaning step; Control the drainage and water inlet of the cleaning machine; The cleaning machine is controlled to run the second pollutant cleaning step at least once when water intake is completed, until the operation status information indicates that the preset pollutant removal conditions are met, and it is determined that the operation status information indicates that the cleaning machine has completed the pollutant cleaning.

[0045] In this embodiment, by dividing the pollutant cleaning mode into a first pollutant cleaning step and a second pollutant cleaning step, and running the first pollutant cleaning step at least once and the second pollutant cleaning step at least once, it is ensured that pollutants can be completely removed and cleanliness is guaranteed.

[0046] In some embodiments, the operating status information includes first turbidity information, the first turbidity information includes at least one first turbidity value, the first turbidity value representing a turbidity value within the cleaning machine detected after the cleaning machine performs a first contaminant cleaning step once, and controlling the cleaning machine to perform the first contaminant cleaning step at least once includes: controlling the power of the cleaning pump to be a first preset power and cleaning the cleaning machine at the first preset power; If the first turbidity information is monitored to meet the preset drainage condition, the step of controlling the cleaning machine to drain water and then fill water is executed; the first turbidity information meeting the preset drainage condition means that at least one first turbidity value in the first turbidity information is greater than or equal to a preset turbidity average value, or at least two first turbidity values are both less than the preset turbidity average value and the difference between the two first turbidity values is between 0 and 1 NTU; If it is monitored that the first turbidity information does not meet the preset drainage condition, the steps of controlling the cleaning pump power to be the first preset power and cleaning the cleaning machine at the first preset power are repeated until the first turbidity information meets the preset drainage condition.

[0047] By repeatedly obtaining the first turbidity information of the cleaning machine and repeatedly increasing the cleaning pump power to clean the cleaning machine, it is possible to promptly determine whether the pollutants have been removed. When at least one first turbidity value is greater than or equal to the preset turbidity average, or when at least two first turbidity values are both less than the preset turbidity average and the difference between the two first turbidity values is between 0 and 1 NTU, it is determined that the pollutants can be preliminarily cleaned and the next step of the process is carried out.

[0048] Specifically, after controlling the power of the cleaning pump to be a first preset power and cleaning the cleaning machine at the first preset power, the method further includes: If the monitored operating status information meets the preset safety condition, the motor power of the cleaning pump is controlled to decrease from the first preset power to the second preset power and continue for a preset time. The preset safety condition means that the running time of the motor power of the cleaning pump at the first preset power reaches the preset running time or the temperature of the motor coil reaches the preset temperature; If the monitored operating status information does not meet the preset safety conditions, the motor power of the cleaning pump is controlled to continue running at the first preset power until the preset safety conditions are met.

[0049] Specifically, the specific process of controlling the cleaning machine to run the first pollutant cleaning step at least once includes: S21: controlling the power of the cleaning pump to be a first preset power and cleaning the cleaning machine at the first preset power; S22: Determine whether the motor power of the cleaning pump reaches the preset running time or the temperature of the motor coil reaches the preset temperature. If so, execute step S23; if not, repeat steps S21-S22; S23: Control the motor power of the cleaning pump to decrease from the first preset power to the second preset power and continue for a preset time, and then execute step S24; S24: Determine whether the first turbidity value is greater than or equal to a preset turbidity average value. If so, execute step S25; if not, execute step S26; S25: Control the draining and water intake of the cleaning machine; S26: Determine whether the first turbidity value is less than a preset turbidity mean value and whether the difference between the two first turbidity values is between 0 and 1 NTU. If so, execute step S25; if not, execute step S27. S27: Repeat steps S21-S26.

[0050] In some embodiments, the operating status information includes a second initial turbidity value and second turbidity information, the second initial turbidity value being used to indicate a turbidity value measured after the cleaning machine completes at least one first contaminant cleaning step and completes water intake, and the second turbidity information includes at least one second turbidity value, the second turbidity value representing a turbidity value detected in the cleaning machine after the cleaning machine performs one second contaminant cleaning step; Controlling the cleaning machine to run the second contaminant cleaning step at least once in a state where water intake is completed, comprising: controlling the power of the cleaning pump to be a first preset power and cleaning the cleaning machine at the first preset power; If the second turbidity information is monitored to meet the preset pollutant removal condition, determining that the operating status information indicates that the cleaning machine has completed the cleaning of pollutants, the second turbidity information meeting the preset pollutant removal condition means that at least two second turbidity values are greater than the second turbidity initial value; If it is monitored that the second turbidity information does not meet the preset pollutant removal condition, the steps of controlling the cleaning pump power to the first preset power and cleaning the cleaning machine at the first preset power are repeated until the second turbidity information meets the preset pollutant removal condition.

[0051] By repeatedly acquiring the second turbidity information, it is possible to determine whether the pollutants have been completely removed after the cleaning pump increases its power to the first preset power. If not, the power of the cleaning pump is continued to be increased to the first preset power until the pollutants are completely removed, thereby ensuring cleanliness.

[0052] Specifically, after controlling the power of the cleaning pump to be a first preset power and cleaning the cleaning machine at the first preset power, the method further includes: If the monitored operating status information meets the preset safety condition, the motor power of the cleaning pump is controlled to decrease from the first preset power to the second preset power and continue for a preset time. The preset safety condition means that the running time of the motor power of the cleaning pump at the first preset power reaches the preset running time or the temperature of the motor coil reaches the preset temperature; If the monitored operating status information does not meet the preset safety conditions, the motor power of the cleaning pump is controlled to continue running at the first preset power until the preset safety conditions are met.

[0053] Specifically, the specific process of controlling the cleaning machine to run the second contaminant cleaning step at least once includes: S28: Controlling the power of the cleaning pump to a first preset power and cleaning the cleaning machine at the first preset power; S29: Determine whether the motor power of the cleaning pump reaches the preset running time or the temperature of the motor coil reaches the preset temperature. If so, execute step S30; if not, repeat steps S28-S29; S30: Control the motor power of the cleaning pump to decrease from the first preset power to the second preset power and continue for a preset time, and then execute step S31; S31: Determine whether the second turbidity value is greater than the second initial turbidity value. If so, execute step S32; if not, execute step S33; S32: Repeat S28-S31 to determine whether the second turbidity value is greater than the second initial turbidity value. If so, execute step S34; if not, execute step S33; S33: Repeat S28-S32; S34: Determine whether the operation status information indicates that the cleaning machine has completed cleaning of the contaminants.

[0054] S3: When the operation status information indicates that the cleaning machine has completed cleaning of the pollutants, the cleaning machine is controlled to switch to a preset cleaning mode.

[0055] Specifically, the preset cleaning mode may be a strong cleaning mode or a non-strong cleaning mode, or the preset cleaning mode may be a cleaning mode received by the cleaning machine after it is currently started.

[0056] The present invention also protects a cleaning device 100 of a cleaning machine, such as Figure 2 As shown, the cleaning machine includes a cleaning pump, the cleaning pump includes a motor, and the motor is provided with a motor coil.
