[0039] Embodiment 1

[0040] The present embodiment provides a control method of a cleaning machine. The cleaning machine comprises a cleaning tank, a water inlet valve and a refrigeration device, the refrigeration device is used for cooling the water inlet pipeline, and the water inlet valve is communicated with the cleaning tank through the water inlet pipeline.

[0041] As shown in Figure 1 , the control method of the cleaning machine comprises the following steps:

[0042] S1, determining the preservation temperature of the target fruits and vegetables put into the cleaning tank.

[0043] S2, controlling the operation of the refrigeration device and the action of the water inlet valve according to the environmental temperature of the cleaning tank, the preservation temperature and the temperature of the water inlet pipeline.

[0044] In a specific example, the structure of the cleaning machine can be as shown in Figure 2 , the cleaning machine comprises a cleaning tank 11, a water inlet valve 12 and a refrigeration device 13, the refrigeration device 13 is arranged on the water inlet pipeline and is used for cooling the water inlet pipeline, the water inlet valve 12 is communicated with the cleaning tank 11 through the water inlet pipeline, and the control of the opening of the water inlet valve 12 can make the water flow in the water inlet pipeline enter the cleaning tank 11.

[0045] In this embodiment, there are many types of fruits and vegetables, and different fruits and vegetables have different preservation requirements. This embodiment will collect preservation data of common fruits and vegetables, establish a preservation database, and perform fruit and vegetable preservation operations based on this data. Preservation temperature needs to be considered when preserving fruits and vegetables. For example, the preservation temperature for tropical fruits is 20℃, for subtropical fruits it is 10℃, and for vegetables it is 5℃, etc. Using different preservation parameters according to the type of fruit and vegetable can prevent damage, ensure optimal preservation effect, and extend the shelf life of fruits and vegetables.

[0046] In this embodiment, the washing machine first determines the type of the target fruits and vegetables placed in the washing tank, and then determines the parameters in the corresponding washing and preservation database based on the type of fruits and vegetables.

[0047] Specifically, determining the type of fruits and vegetables to be placed in the washing tank can be achieved using image recognition technology. This method is convenient and quick, saving users time and effort. Alternatively, users can actively select the types of fruits and vegetables to be placed in the washing tank. This method is low-cost, has a wider range of applications, and is more flexible for users, allowing them to choose the most suitable option based on their daily experience and common sense.

[0048] In this embodiment, a verification step to determine whether fruits and vegetables are in the washing tank may also be included. This can be achieved using image recognition technology to intelligently identify whether the user has removed the fruits and vegetables, or by allowing the user to manually select whether to remove them, or by weighing the washing tank to detect whether the fruits and vegetables have been removed. If the fruits and vegetables are in the washing tank for more than a time period T, a preservation operation is performed, i.e., step S2 described above is executed. If the user removes all the fruits and vegetables within the time period T, the preservation operation is stopped. The time period T can be 5 minutes, 10 minutes, half an hour, etc., and can be set according to the actual situation.

[0049] In a specific example, before preserving fruits and vegetables, the washing machine also cleans them. The machine first determines the type of fruit or vegetable to be placed in the washing tank, and then determines parameters such as washing intensity and time based on that type. For example, different types of fruits and vegetables, such as root vegetables, leafy greens, and berries, require different washing intensities and times. The washing machine controls the operation of the water inlet, drain, washing pump, and ultrasonic transducer based on these parameters to clean the fruits and vegetables before preserving them. Thus, the washing machine combines cleaning and preservation functions, bringing convenience to users.

[0050] In one optional implementation, step S2 specifically includes: if the ambient temperature of the cleaning tank is greater than the first target temperature, then controlling the refrigeration device to start operating; wherein the first target temperature is determined based on the preservation temperature; if the temperature of the water inlet pipe is less than the second target temperature, then controlling the refrigeration device to stop operating, and controlling the water inlet valve to be opened for a period of time and then closed, so that the amount of water entering the cleaning tank reaches the first water inlet amount; wherein the second target temperature is determined based on the preservation temperature.

[0051] In this embodiment, water flows through the inlet pipe and enters the cleaning tank through the inlet valve. The refrigeration device can be an ice chamber, compressor, or other device with refrigeration capabilities. During operation, the refrigeration lowers the temperature of the inlet pipe, and the water flowing through the inlet pipe is transformed into ice water with a temperature lower than the second target temperature. Specifically, the first and second target temperatures are determined based on the preservation temperature. For example, the first target temperature is the preservation temperature plus 5°C, and the second target temperature is the preservation temperature minus 5°C. When the ambient temperature of the cleaning tank is below the first target temperature, it meets the fruit and vegetable preservation standards. Since the water flowing through the tank is ice water with a temperature lower than the second target temperature, it can help lower the ambient temperature of the cleaning tank.

[0052] Specifically, a filter can be installed at the front end of the water inlet pipe to prevent impurities in the water from entering the water inlet pipe, thereby extending the service life of the equipment, improving water quality, and ensuring the health of users.

[0053] In a specific example, when the ambient temperature of the cleaning tank is detected to be higher than the first target temperature, the ice tank is activated. After a period of time, the water temperature in the inlet pipe decreases, becoming ice water with a temperature lower than the second target temperature. The ice tank then stops operating, and the inlet valve is activated to allow ice water to enter the cleaning tank. When the amount of water entering the cleaning tank reaches the first inlet volume, the inlet valve is closed. The first inlet volume is pre-set and corresponds to the size of the cleaning tank.

[0054] In one optional embodiment, a cleaning pump is provided in the cleaning tank, and the control method of the cleaning machine further includes: after the water inlet valve is closed.

[0055] S3. Control the operation of the cleaning pump according to the ambient temperature and preservation temperature of the cleaning tank.

[0056] In this embodiment, when the water volume in the cleaning tank is the first inlet water volume, it can submerge the impeller of the cleaning pump motor.

[0057] In one optional implementation, step S3 specifically includes:

[0058] S31. If the ambient temperature of the cleaning tank is higher than the third target temperature, the cleaning pump will start running; wherein the third target temperature is determined based on the preservation temperature.

[0059] S32. If the running time of the cleaning pump does not reach the first duration and the ambient temperature of the cleaning tank is lower than the first target temperature, then control the cleaning pump to stop running; wherein, the third target temperature is higher than the first target temperature.

[0060] In this embodiment, the third target temperature is determined based on the preservation temperature and is higher than the first target temperature. For example, the third target temperature is 10°C higher than the preservation temperature. At this temperature, the temperature inside the washing tank is high, which is detrimental to the preservation of fruits and vegetables and requires rapid cooling. Therefore, if the ambient temperature of the washing tank is detected to be higher than the third target temperature, the washing pump is controlled to operate. During the operation of the washing pump, water in the washing tank is sprayed into the washing tank as the pump rotates, thereby quickly reducing the temperature inside the entire washing tank and ensuring the preservation effect of fruits and vegetables. While the washing pump is rotating and spraying in the washing tank, the ambient temperature inside the washing tank is monitored in real time. If the ambient temperature inside the washing tank successfully decreases within a short period of time, that is, the running time of the washing pump has not reached the first duration and the ambient temperature of the washing tank is less than or equal to the first target temperature, the washing pump is controlled to stop operating, and the spraying operation is stopped to prevent over-washing of fruits and vegetables.

[0061] In one optional embodiment, the cleaning machine further includes a drain valve, and the cleaning tank is connected to a drain pipe via the drain valve; the control method of the cleaning machine further includes:

[0062] S4. If the running time of the cleaning pump reaches the first duration and the ambient temperature of the cleaning tank is greater than or equal to the first target temperature, then control the cleaning pump to stop running and control the drain valve to open.

[0063] In this embodiment, if the ambient temperature of the cleaning tank has not successfully dropped below the first target temperature after the cleaning pump has been running for a first duration, the water temperature in the cleaning tank will rise and will no longer be able to help lower the ambient temperature of the cleaning tank. Therefore, the cleaning pump will be stopped to prevent damage to the cleaning pump due to excessive operation. At the same time, the drain valve will be opened to drain the water in the cleaning tank to prevent it from affecting the subsequent ice water filling operation.

[0064] In a specific example, the washing pump can rotate according to the acceptable washing intensity corresponding to the identified fruit and vegetable type, preventing damage to the target fruit and vegetable. Specifically, different fruit and vegetable types correspond to different rotation speeds, and different washing intensities can be achieved by the washing pump operating at different speeds.

[0065] In one optional embodiment, the cleaning machine further includes a drain valve, and the cleaning tank is connected to a drain pipe via the drain valve; after step S32, the following is also included:

[0066] The system starts the refrigeration unit; if the temperature of the inlet water pipe is lower than the second target temperature, the system stops the refrigeration unit and controls the inlet water valve to open for a period of time and then close it, so that the water volume entering the cleaning tank reaches the maximum inlet volume; if the water volume in the cleaning tank reaches the maximum inlet volume for a second period of time, and the ambient temperature of the cleaning tank is greater than or equal to the first target temperature, the system controls the drain valve to open.

[0067] In this embodiment, the ambient temperature of the cleaning tank is already lower than the first target temperature, and the cooling operation is complete. However, it is still necessary to maintain the ambient temperature of the cleaning tank. Therefore, the cooling device is started to lower the temperature in the water inlet pipe. After the cooling device has been running for a period of time, the temperature in the water inlet pipe is lower than the second target temperature, indicating that cooling is complete. At this point, the cooling device is stopped, and the water inlet valve is opened to slowly introduce ice water into the cleaning tank. When the amount of water entering the cleaning tank reaches the maximum inlet volume, the water inlet valve is closed. The maximum inlet volume is the sum of the aforementioned first inlet volume and the current inlet volume.

[0068] Specifically, during the process of slowly introducing ice water into the washing tank, the ambient temperature inside the washing tank is monitored in real time. If the ambient temperature inside the washing tank drops to the preservation temperature of the target fruits and vegetables during the process, the water inlet valve can be directly closed without waiting for the water volume entering the washing tank to reach the maximum water volume, so as to prevent the temperature from being too low due to too much ice water.

[0069] In this embodiment, when the water volume entering the cleaning tank reaches the maximum water volume and the water inlet valve is closed for the second duration, if the ambient temperature of the cleaning tank is greater than or equal to the first target temperature, the water temperature in the cleaning tank will rise and will no longer be able to help lower the ambient temperature of the cleaning tank. Therefore, the drain valve is opened to drain the water in the cleaning tank to prevent it from affecting the subsequent ice water entry operation.

[0070] Specifically, when the water intake in the washing tank is at its maximum, the water level remains below the position of the washing basket containing the fruits and vegetables in the washing tank, to prevent the fruits and vegetables from being soaked in water and rotting.

[0071] In one specific embodiment, the preservation temperature of the target fruits and vegetables is 10°C, the first target temperature is 15°C, the second target temperature is 5°C, and the third target temperature is 20°C. The refrigeration device is an ice chamber. When it is determined that the target fruits and vegetables have been in the washing tank for more than 5 minutes, the preservation operation begins.

[0072] The first step is to lower the ambient temperature of the cleaning tank. If the ambient temperature is detected at 25℃, which is 15℃ higher than the first target temperature, the ice tank is activated. Operation continues until the temperature in the inlet pipe is 5℃ lower than the second target temperature. At this point, the ice tank stops, the inlet valve is opened, and the first volume of 5℃ ice water is introduced into the cleaning tank. The inlet valve is then closed. With the water intake complete, the ambient temperature of the cleaning tank decreases. If the temperature drops to 23℃, which is still higher than the third target temperature of 20℃, the cleaning pump is activated. It rotates according to the acceptable cleaning intensity corresponding to the identified fruit and vegetable type, spraying the cold water into the cleaning tank. The cleaning pump's operating time does not exceed the first set of time limits. The ambient temperature of the cleaning tank is monitored in real time during pump operation, and the pump's operation is controlled accordingly. For example, if the ambient temperature of the cleaning tank drops to 13℃ within the first set of time limits, which is lower than the first target temperature of 15℃, the cleaning pump is stopped prematurely. In another example, if the cleaning pump runs for a certain period of time and the ambient temperature of the cleaning tank has not dropped below the first target temperature of 15°C, the cleaning pump will be forcibly stopped and the drain valve will be opened to drain the water from the cleaning tank. The above steps will then be repeated.

[0073] The next step is to maintain the ambient temperature of the cleaning tank. If the ambient temperature of the cleaning pump has dropped below the first target temperature of 15°C, restart the ice tank until the water temperature in the inlet pipe is 5°C lower than the second target temperature. Then, stop the ice tank, open the inlet valve, and slowly introduce ice water into the cleaning tank. If the ambient temperature of the cleaning tank drops to the preservation temperature of 10°C during this process, close the inlet valve directly to prevent the temperature from dropping too low. Otherwise, open the inlet valve until the water volume entering the cleaning tank reaches the maximum, then close the inlet valve. If the ambient temperature of the cleaning tank gradually rises above the first target temperature of 15°C during the second time the inlet valve is closed, open the drain valve and repeat the above steps until the ambient temperature of the cleaning tank drops below the first target temperature of 15°C.
