Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a water pump control method, device, household appliance, and storage medium. Background Technology

[0002] In the air conditioning industry, air conditioners produce condensate when performing the cooling function and humidification water when performing the humidification function. Therefore, air conditioners are usually equipped with a corresponding drip tray to receive condensate or humidification water, and a water pump is installed in the drip tray to drain the water from the drip tray.

[0003] However, in related technologies, when controlling the water pump, its lifespan is far shorter than that of the entire air conditioner, thus limiting the actual lifespan of the air conditioner. For example, the lifespan of the fresh air unit in a radiant air conditioner can reach 47,000 hours, while the water pump's lifespan is only up to 20,000 hours, resulting in a reduced overall lifespan for the radiant air conditioner.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the first objective of this invention is to propose a water pump control method that, for different operating conditions, uses corresponding target start-stop times to control the water pump, thereby improving the service life of the water pump without affecting the drainage performance of the target equipment, and thus extending the actual service life of the target equipment.

[0006] A second objective of this invention is to provide a computer-readable storage medium.

[0007] The third objective of this invention is to provide a household appliance.

[0008] The fourth objective of this invention is to provide a water pump control device.

[0009] To achieve the above objectives, a first aspect of the present invention provides a water pump control method. The water pump is located in the water receiving pan of a target device and is used to discharge water from the water receiving pan. The method includes: acquiring the water production flow rate of the target device; determining the operating condition of the target device based on the water production flow rate; determining the target start-stop time of the water pump based on the operating condition; wherein the target device includes multiple operating conditions, and different operating conditions correspond to different target start-stop times; and controlling the water pump according to the target start-stop times.

[0010] According to the water pump control method of this invention, the water production flow rate of the target equipment is obtained, the operating condition of the target equipment is determined based on the water production flow rate, the target start-stop time of the water pump is determined based on the operating condition, and the water pump is controlled according to the target start-stop time. Therefore, by using corresponding target start-stop times to control the water pump for different operating conditions, the service life of the water pump can be improved without affecting the drainage performance of the target equipment, thereby increasing the actual service life of the target equipment.

[0011] In some embodiments of the present invention, the target start-stop working time corresponding to each operating condition is determined in advance based on the maximum water production flow rate of the target equipment, the maximum water storage capacity of the water receiving pan, the overall service life of the target equipment, the drainage flow rate of the water pump, the service life of the water pump, the start-stop life of the water pump, and the proportion of the running time of each operating condition in multiple operating conditions.

[0012] In some embodiments of the present invention, the target start-stop time corresponding to each operating condition is determined in advance by the following method:

[0013]

[0014] Where m is the maximum water capacity of the water tray, k is a preset coefficient, and t 1i t 2i V represents the target start-up time and target stop time of the water pump corresponding to the i-th operating condition. 0i Let V1 be the maximum water production flow rate of the target equipment corresponding to the i-th operating condition, x be the number of operating conditions, T0 be the service life of the entire machine, and ω be the maximum water production flow rate of the target equipment corresponding to the i-th operating condition. 1i T1 represents the percentage of the operating time of the i-th operating condition across multiple operating conditions, T1 represents the pump's service life, and N represents the pump's start-stop life.

[0015] In some embodiments of the present invention, when the target device is a refrigeration device, the operating conditions include minimum refrigeration condition, rated refrigeration condition and maximum refrigeration condition, and the water production flow rate corresponding to the minimum refrigeration condition, rated refrigeration condition and maximum refrigeration condition increases sequentially, the target start-up time of the corresponding water pump increases sequentially, and the target stop-up time of the corresponding water pump decreases sequentially.

[0016] In some embodiments of the present invention, determining the operating condition of the target equipment based on the product water flow rate includes: determining the operating condition of the target equipment as the minimum cooling condition when the product water flow rate is in a first flow range; determining the operating condition of the target equipment as the rated cooling condition when the product water flow rate is in a second flow range; wherein the flow rate in the second flow range is greater than the flow rate in the first flow range; and determining the operating condition of the target equipment as the maximum cooling condition when the product water flow rate is in a third flow range; wherein the flow rate in the third flow range is greater than the flow rate in the second flow range, and the maximum value of each flow range is the maximum product water flow rate of the target equipment corresponding to the corresponding operating condition.

[0017] In some embodiments of the present invention, the target start-stop working time includes a target start working time and a target stop working time. Controlling the water pump according to the target start-stop working time includes: controlling the water pump to start working; controlling the water pump to stop working when the start working time of the water pump reaches the target start working time; controlling the water pump to start working again when the stop working time of the water pump reaches the target stop working time, and so on.

[0018] To achieve the above objectives, a second aspect of the present invention provides a computer-readable storage medium having a program stored thereon that, when executed by a processor, implements the water pump control method of any of the above embodiments.

[0019] According to the computer-readable storage medium of the present invention, based on the above-described pump control method, the pump is controlled by adopting corresponding target start-stop times for different operating conditions, which can improve the service life of the pump without affecting the drainage performance of the target equipment, thereby improving the actual service life of the target equipment.

[0020] To achieve the above objectives, a third aspect of the present invention provides a household appliance comprising: a memory, a processor, and a program stored in the memory and executable on the processor, wherein when the processor executes the program, it implements the water pump control method of any of the above embodiments.

[0021] According to the embodiments of the present invention, the water pump control method described above is used to control the water pump with corresponding target start-stop times for different operating conditions. This can improve the service life of the water pump without affecting the drainage performance of the target equipment, thereby improving the actual service life of the target equipment.

[0022] To achieve the above objectives, a fourth aspect of the present invention provides a water pump control device. The water pump is located in the water receiving pan of a target device and is used to discharge water from the water receiving pan. The device includes: an acquisition module for acquiring the water production flow rate of the target device; and a control module for determining the operating condition of the target device based on the water production flow rate, determining the target start-stop time of the water pump based on the operating condition, and controlling the water pump based on the target start-stop time. The target device includes multiple operating conditions, and different operating conditions correspond to different target start-stop times.

[0023] According to an embodiment of the present invention, the water pump control device acquires the water production flow rate of the target device through an acquisition module, determines the operating condition of the target device based on the water production flow rate through a control module, determines the target start-stop time of the water pump based on the operating condition, and controls the water pump based on the target start-stop time. Therefore, by using corresponding target start-stop times to control the water pump for different operating conditions, the service life of the water pump can be improved without affecting the drainage performance of the target device, thereby extending the actual service life of the target device.

[0030] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] The following describes in detail, with reference to the accompanying drawings, the water pump control method, device, household appliance, and storage medium according to embodiments of the present invention.

[0032] Figure 1 This is a schematic flowchart of a water pump control method according to an embodiment of the present invention.

[0033] In an embodiment of the present invention, a water pump is located in the water receiving tray of the target device and is used to drain the water in the water receiving tray.

[0034] It should be noted that the target device can be a refrigeration device (such as an air conditioner), a dehumidifier, etc. There are no specific restrictions here. For ease of explanation, the following explanation will use an air conditioner as the target device.

[0035] like Figure 1 As shown, the water pump control method may include:

[0036] S11: Obtain the water production flow rate of the target device.

[0037] For example, when the air conditioner is running in cooling mode, condensate will be generated and flow into the water collection pan inside the air conditioner. During this process, the condensate flow rate of the air conditioner, i.e. the water production flow rate of the air conditioner, can be calculated based on the temperature and humidity of the air inlet and outlet of the air conditioner.

[0038] S13: Determine the operating conditions of the target equipment based on the water production flow rate.

[0039] It should be noted that the target equipment includes multiple operating conditions, and the amount of condensate produced by the air conditioner varies under different operating conditions. Therefore, the operating condition of the target equipment can be determined based on the water production flow rate of the target equipment.

[0040] For example, when the air conditioner is operating at a high cooling capacity, it produces more condensate, while when it is operating at a low cooling capacity, it produces less condensate. Therefore, the current operating condition of the air conditioner can be determined based on its water production flow rate.

[0041] In some embodiments, when the target device is a refrigeration device such as an air conditioner, the operating conditions can be divided into three types: minimum cooling condition, rated cooling condition, and maximum cooling condition, with the water production flow rate corresponding to the minimum cooling condition, rated cooling condition, and maximum cooling condition increasing sequentially. The minimum cooling condition refers to the condition where the refrigeration device operates at its minimum cooling capacity; the rated cooling condition refers to the condition where the refrigeration device operates at its rated cooling capacity; and the maximum cooling condition refers to the condition where the refrigeration device operates at its maximum cooling capacity.

[0042] S15: Determine the target start-up and shutdown time of the water pump based on the operating conditions.

[0043] It should be noted that different operating conditions correspond to different target start-up and shutdown times. Target start-up and shutdown times can include target start-up time and target stop time.

[0044] For example, when the air conditioner is operating at a high cooling capacity, it produces more condensate, resulting in a longer target start-up time for the water pump. Conversely, when the air conditioner is operating at a low cooling capacity, it produces less condensate, resulting in a shorter target start-up time for the water pump.

[0045] In some embodiments, when the target device is a refrigeration device such as an air conditioner, the operating conditions can be divided into three types: minimum cooling condition, rated cooling condition, and maximum cooling condition, and the target start-up time of the corresponding water pump increases sequentially, while the target stop-up time of the corresponding water pump decreases sequentially.

[0046] For example, when the air conditioner's water flow rate is low, it can be considered to be in its minimum cooling condition. In this case, the target start-up time of the water pump can be set to a smaller value, while the target stop-up time can be set to a larger value. This reduces the water pump's operating time and the number of starts while ensuring that the water in the drip tray is drained in a timely manner. When the air conditioner's water flow rate is high, it can be considered to be in its maximum cooling condition. In this case, the target start-up time of the water pump can be set to a larger value, while the target stop-up time can be set to a smaller value, ensuring that the water in the drip tray is drained in a timely manner. Compared to the method of using a larger target start-up time and a smaller target stop-up time for all cooling operation conditions during air conditioner operation (to ensure that the water under the maximum cooling condition is drained in a timely manner), this method reduces the water pump's operating time and the number of starts and stops to a certain extent, thereby extending the water pump's service life. At the same time, compared with the method of keeping the water pump in the starting state for all cooling operation conditions during the cooling process of the air conditioner, this method greatly reduces the working time of the water pump and extends its service life. Although the number of start-stop cycles increases with this method, the service life of the water pump can still be extended through proper settings.

[0047] S17: Control the water pump according to the target start-up and shutdown time.

[0048] In some embodiments, controlling the water pump according to a target start-stop time includes: controlling the water pump to start; controlling the water pump to stop when the start-up time reaches the target start-up time; controlling the water pump to start again when the stop time reaches the target stop time, and so on.

[0049] In other words, the water pump is controlled to operate intermittently based on the target start-up time and target stop-work time.

[0050] For example, during the cooling operation of an air conditioner, condensate is generated and flows into the air conditioner's drip tray. During this process, the condensate flow rate, i.e., the water production flow rate, is obtained. Based on the water production flow rate, the target start-up time and target stop-up time of the water pump in the drip tray are determined. The water pump is controlled to operate according to the target start-up time until the water pump's start-up time reaches the target start-up time to drain all the water in the drip tray. Then, the water pump is controlled to stop operating. During this process, the air conditioner will still generate condensate. When the water pump's stop-up time reaches the target stop-up time, the water pump is controlled to start operating again to drain the water in the drip tray in a timely manner. This process is repeated until the cooling mode is exited, etc.

[0051] In the above embodiments, by determining the target start-up and shutdown time of the target equipment based on the water production flow rate of the target equipment, and controlling the water pump to work intermittently based on the target start-up and shutdown time, it is possible to reduce the continuous operation time and start-up and shutdown frequency of the water pump without affecting the drainage performance of the target equipment, thereby increasing the service life of the water pump and thus increasing the actual service life of the target equipment.

[0052] In some embodiments, the target start-stop working time corresponding to each operating condition is determined in advance based on the maximum water production flow rate of the target equipment, the maximum water storage capacity of the water receiving pan, the overall service life of the target equipment, the drainage flow rate of the water pump, the service life of the water pump, the start-stop life of the water pump, and the proportion of the running time of each operating condition in multiple operating conditions.

[0053] It should be noted that the maximum water production flow rate of the target equipment refers to the maximum water flow rate generated per unit time during operation. For example, in the case of refrigeration equipment such as an air conditioner operating at its minimum cooling capacity, the maximum water production flow rate refers to the maximum water flow rate generated per unit time during operation. The maximum water capacity of the drip tray refers to the maximum amount of water the drip tray can hold. The overall service life of the target equipment refers to the service life achievable under the corresponding design standards. For example, the overall service life of a radiant air conditioner is 47,000 hours. The drainage flow rate of the water pump refers to the amount of water that the pump can discharge per unit time. The service life of the water pump refers to the maximum continuous operating time of the water pump under the corresponding design standards. For example, the service life of the water pump is 20,000 hours. The start-stop life of the water pump refers to the maximum number of start-stop cycles of the water pump under the corresponding design standards. For example, the start-stop life of the water pump is 100,000 cycles. The duty cycle of each operating condition across multiple operating conditions can be determined through experiments or actual usage data. For example, when a refrigeration device includes a minimum refrigeration condition, a rated refrigeration condition, and a maximum refrigeration condition, the duty cycle of the minimum refrigeration condition across the three operating conditions is 25%, the duty cycle of the rated refrigeration condition across the three operating conditions is 70%, and the duty cycle of the maximum refrigeration condition across the three operating conditions is 5%.

[0054] When determining the target start-stop time for each operating condition based on the above parameters, the following principles can be used:

[0055] (1) For each operating condition, during the time when the water pump stops working, the water production of the target equipment shall not exceed the maximum water storage capacity of the water receiving pan, and a certain margin can be left.

[0056] (2) For each operating condition, during the pump start-up working time, the pump discharge is greater than the total water production of the target equipment during the pump stop working time and start-up working time, and a certain margin can be left.

[0057] (3) The continuous working life of the water pump under multiple operating conditions is less than or equal to the service life of the water pump.

[0058] (4) The start-stop service life of the water pump under multiple operating conditions is less than or equal to the start-stop service life of the water pump.

[0059] Thus, by pre-determining the target start-stop time for each operating condition based on the aforementioned parameters, the continuous operating time and number of start-stop cycles of the water pump can be reduced while ensuring that the water in the receiving pan is drained in a timely manner. This increases the service life of the water pump and consequently, the service life of the target equipment. For example, when it is necessary to increase the service life and start-stop life of the water pump, these values ​​can be set as target values. Under this constraint, the requirements can be met by adjusting the start-stop time of the water pump, and this method is universal.

[0060] In some embodiments, the target start-stop working time corresponding to each operating condition can be calculated in advance using the following formula (1):

[0061]

[0062] Where m is the maximum water capacity of the water tray, k is the preset coefficient (also known as the safety factor, to leave a certain margin), and t 1i t 2i V represents the target start-up time and target stop time of the water pump corresponding to the i-th operating condition. 0i Let V1 be the maximum water production flow rate of the target equipment corresponding to the i-th operating condition, x be the number of operating conditions, T0 be the service life of the entire machine, and ω be the maximum water production flow rate of the target equipment corresponding to the i-th operating condition. 1i T1 represents the percentage of the operating time of the i-th operating condition across multiple operating conditions, T1 represents the pump's service life, and N represents the pump's start-stop life.

[0063] For example, there are three operating conditions: minimum cooling condition, rated cooling condition, and maximum cooling condition. The target start-up time and target stop time of the water pump under each of the three operating conditions can be calculated using the above formula.

[0064] It should be noted that each sub-formula in the above formula corresponds to one of the four principles mentioned above. Thus, by reasonably setting the target start-up and shutdown time of the water pump, not only can the water in the receiving pan be discharged in a timely manner, but the service life of the water pump can also be extended, thereby extending the service life of the target equipment.

[0065] In some embodiments, refer to Figure 2 The operating conditions of the target equipment are determined based on the water production flow rate, including:

[0066] S21: When the water production flow rate is in the first flow range, determine the operating condition of the target equipment as the minimum cooling condition.

[0067] S23: When the product water flow rate is in the second flow range, the operating condition of the target equipment is determined to be the rated cooling condition. The flow rate in the second flow range is greater than the flow rate in the first flow range.

[0068] S25: When the product water flow rate is in the third flow rate range, the operating condition of the target equipment is determined as the maximum cooling condition. The flow rate in the third flow rate range is greater than the flow rate in the second flow rate range, and the maximum value of each flow rate range is the maximum product water flow rate of the target equipment corresponding to the respective operating condition.

[0069] In other words, the water production flow rate of the target equipment can be divided into three levels, with each level corresponding to a different operating condition. For example, when the water production flow rate is low, it corresponds to the minimum cooling condition; when the water production flow rate is in the middle, it corresponds to the rated cooling condition; and when the water production flow rate is high, it corresponds to the maximum cooling condition.

[0070] For example, the target start-stop operating time of the water pump under minimum cooling condition, the target start-stop operating time of the water pump under rated cooling condition, and the target start-stop operating time of the water pump under maximum cooling condition can be calculated in advance according to the above formula, and the calculation results can be stored in the air conditioner in advance.

[0071] Then, during the air conditioner's cooling operation, the system acquires the air conditioner's water production flow rate and determines the flow range it falls within. If it falls within the first flow range, the system acquires the target start-stop time for the water pump corresponding to the minimum cooling condition; if it falls within the second flow range, the system acquires the target start-stop time for the water pump corresponding to the rated cooling condition; and if it falls within the third flow range, the system acquires the target start-stop time for the water pump corresponding to the maximum cooling condition. Based on the acquired target start-stop times, the system controls the water pump's start and stop to promptly drain the water from the drip tray.

[0072] It should be noted that the formula above uses the maximum water production flow of the target equipment under various operating conditions, and the maximum value of each flow range is the maximum water production flow of the target equipment corresponding to the corresponding operating condition. Compared with the calculation of the target start-up and shutdown time of the water pump based on the water production flow of the target equipment and the relationship between the water production flow of the target equipment and the target start-up and shutdown time of the water pump, the service life of the water pump is determined.

[0073] Specifically, assuming that after obtaining the water production flow rate of the target equipment, it is substituted into the above formula, then when the water production flow rate of the target equipment is less than the maximum water production flow rate under the corresponding operating conditions, the corresponding pump lifespan and pump start-stop lifespan may increase, thus making it impossible to guarantee that the pump lifespan and pump start-stop lifespan are at a fixed value, resulting in uncontrollable pump lifespan and pump start-stop lifespan. However, in the above embodiment, using a fixed maximum water production flow rate of the target equipment ensures that the pump lifespan and pump start-stop lifespan are controllable.

[0074] To verify that the pump's service life and start-stop life meet the requirements, corresponding experiments were conducted, and the experimental data are shown in Tables 1-3. As can be seen from Tables 1-3, under minimum cooling conditions, rated cooling conditions, and maximum cooling conditions, the average start-stop life of the pump is 91,197 cycles, and the pump's service life is 16,685 hours, meeting the requirements of a pump service life of 20,000 hours and a start-stop cycle count of 100,000.

[0083] It should be noted that the specific values ​​mentioned above are only for illustrating the implementation of the present invention in detail, and should not be construed as limiting the present invention. In other examples, implementation methods, or embodiments, other values ​​may be selected according to the present invention, and no specific limitations are made here.

[0084] Corresponding to the above embodiments, embodiments of the present invention also propose a computer-readable storage medium having a program stored thereon, which, when executed by a processor, is the water pump control method of any of the above embodiments.

[0085] According to the computer-readable storage medium of the present invention, the water production flow rate of the target device is acquired by an acquisition module, and the operating conditions of the target device are determined by a control module based on the water production flow rate. The target start-stop time of the water pump is then determined based on the operating conditions, and the water pump is controlled according to the target start-stop time. Therefore, by using corresponding target start-stop times to control the water pump for different operating conditions, the service life of the water pump can be improved without affecting the drainage performance of the target device, thereby extending the actual service life of the target device.

[0086] For example, when the program is executed by the processor, the following water pump control method can be implemented:

[0087] S11: Obtain the water production flow rate of the target device.

[0088] S13: Determine the operating conditions of the target equipment based on the water production flow rate.

[0089] S15: Determine the target start-up and shutdown time of the water pump based on the operating conditions.

[0090] S17: Control the water pump according to the target start-up and shutdown time.

[0091] It should be noted that the above explanation of the embodiments and beneficial effects of the water pump control method is also applicable to the computer-readable storage medium of the embodiments of the present invention. To avoid redundancy, it will not be elaborated in detail here.

[0092] Corresponding to the above embodiments, the present invention also proposes a household appliance. Figure 3 This is a structural block diagram of a household appliance according to an embodiment of the present invention. Figure 3 As shown, the home appliance 50 includes a memory 502, a processor 504, and a program 506 stored in the memory 502 and executable on the processor 504. When the processor 504 executes the program 506, it implements the water pump control method of any of the above embodiments.

[0093] According to the present invention, the household appliance acquires the water flow rate of the target device through an acquisition module, determines the operating condition of the target device based on the water flow rate through a control module, determines the target start-stop time of the water pump based on the operating condition, and controls the water pump based on the target start-stop time. Therefore, by using corresponding target start-stop times to control the water pump for different operating conditions, the service life of the water pump can be improved without affecting the drainage performance of the target device, thereby extending the actual service life of the target device.

[0094] For example, when program 506 is executed by processor 504, the following water pump control method is implemented:

[0095] S11: Obtain the water production flow rate of the target device.

[0096] S13: Determine the operating conditions of the target equipment based on the water production flow rate.

[0097] S15: Determine the target start-up and shutdown time of the water pump based on the operating conditions.

[0098] S17: Control the water pump according to the target start-up and shutdown time.

[0099] It should be noted that the above explanation of the embodiments and beneficial effects of the water pump control method also applies to the household appliance 50 in the embodiments of the present invention. To avoid redundancy, it will not be elaborated in detail here.

[0100] Corresponding to the above embodiments, the present invention also proposes a water pump control device.

[0101] Figure 4This is a structural block diagram of a water pump control device according to an embodiment of the present invention. Figure 4 As shown, the water pump is located in the water receiving pan of the target equipment and is used to discharge the water in the water receiving pan. The water pump control device 60 includes: an acquisition module 602 and a control module 604. The acquisition module 602 is used to obtain the water production flow rate of the target equipment. The control module 602 is used to determine the operating condition of the target equipment according to the water production flow rate, and to determine the target start-stop time of the water pump according to the operating condition, and to control the water pump according to the target start-stop time. The target equipment includes multiple operating conditions, and different operating conditions correspond to different target start-stop times.

[0102] In some embodiments of the present invention, the target start-stop working time corresponding to each operating condition is determined in advance based on the maximum water production flow rate of the target equipment, the maximum water storage capacity of the water receiving pan, the overall service life of the target equipment, the drainage flow rate of the water pump, the service life of the water pump, the start-stop life of the water pump, and the proportion of the running time of each operating condition in multiple operating conditions.

[0103] In some embodiments of the present invention, the target start-stop time corresponding to each operating condition is determined in advance by the following method:

[0104]
