[0040] Embodiments of the present application are described in detail below with reference to the attached drawings, which show by way of example, embodiments in which like numerals indicate like elements or elements having the same or similar function throughout the several figures. The embodiments described below are exemplary and are intended to be illustrative of the present application and are not to be construed as limiting the present application.

[0041] In embodiments of the present application, a water pump is located in a water receiving tray of a target device for draining water in the water receiving tray.

[0042] It should be noted that the target device can be an air conditioner or the like, and is not specifically limited here. For ease of description, the target device is taken as an air conditioner in the following description.

[0043] By way of example, with reference to Figure 1 , the air conditioner includes a water receiving tray, a water pump and a water level switch arranged in the water receiving tray, and a controller. The water receiving tray is used to receive condensate water generated during air conditioning operation, the water pump is used to drain the condensate water in the water receiving tray, and the water level switch is used to detect the water level of the water receiving tray and send a water level signal to the controller. Generally, the controller controls the water pump to work continuously to ensure that the condensate water in the water receiving tray is drained. Since dust, foreign matter and the like in the air can dissolve into the condensate water, and the condensate water can also produce bacteria and breed, resulting in dirty blockage or even blockage of the water pump, thereby causing the drainage flow of the water pump to attenuate. When the drainage flow of the water pump attenuates to less than the condensate water production of the air conditioner, the condensate water in the water receiving tray cannot be drained in time, the controller alarms based on the water level signal, and controls the air conditioner to stop.

[0044] The above-mentioned manner not only causes the user to be unable to continue using the air conditioner, but also, when the water full alarm occurs, it indicates that the drainage system is already very dirty, and there can be a large amount of bacteria, viruses and the like, causing the air blown by the air conditioner to affect the health of the user. In addition, the water level switch and the water pump are in an overloaded state for a long time, reducing their service life, and failure of the water level switch will cause a "bubble top" risk.

[0045] Therefore, in the embodiment of the present application, the water pump is controlled to stop working, and the water pump dirty blockage reminding is performed according to the first time from when the water pump stops working to when the water level reaches the preset water level, so that the user can clean the water receiving tray, the water pump and the water level switch in time, thereby not only reducing the situation that the air conditioner cannot continue to be used due to water fullness, but also making the drainage system in a relatively clean state, reducing the influence on the user's health, and avoiding the water pump and the water level switch being in an overload state for a long time, thereby prolonging the service life of the water pump and the water level switch.

[0046] The water pump control method, device, household appliance and storage medium are described in detail below with reference to the drawings.

[0047] Figure 2 FIG. 1 is a flowchart of a water pump control method according to an embodiment of the present application.

[0048] As shown in FIG. 1, the water pump control method can include: Figure 2

[0049] S11: After the water pump is controlled to stop working, if the water level of the water receiving tray reaches the preset water level within the first preset time, the first time from when the water pump stops working to when the water level reaches the preset water level is obtained.

[0050] It should be noted that the preset water level can be the water level corresponding to the water fullness of the water receiving tray, that is, when the water level reaches the preset water level, it indicates that the water receiving tray is in the water fullness state, and the preset water level can also be referred to as the water fullness alarm water level. The first preset time can be the shortest time for the water in the water receiving tray to reach the preset water level from zero in the process of air conditioner refrigeration operation without the water pump being started, so that not only can the water in the water receiving tray be avoided from being full due to the first preset time being set too long, but also the water in the water receiving tray can be avoided from not reaching the preset water level within the time due to the first preset time being set too short, thereby avoiding inaccurate dirty blockage detection. The preset water level and the first preset time can be set according to actual conditions.

[0051] For example, in the process of air conditioner refrigeration operation, the water pump can be controlled to continuously work for a period of time, and then the water pump is controlled to stop working for dirty blockage detection.

[0052] Under normal circumstances, since the drainage flow of the water pump is greater than the condensate flow generated in the process of air conditioner refrigeration operation, after the water pump continuously works for a period of time, the condensate in the water receiving tray will be completely drained, and then the water pump is controlled to stop working, after the water pump stops working, the air conditioner will continue to generate condensate, and the condensate in the water receiving tray will gradually increase from zero. Through reasonable setting of the first preset time, it can be ensured that the condensate in the water receiving tray will not exceed the preset water level at the first preset time when the water pump stops working, and then the water pump is controlled to continuously work for a period of time.

[0053] ​However, when the water pump is dirty and blocked, the water discharge flow rate of the water pump will decrease during the continuous operation of the water pump. When the water discharge flow rate decreases to less than the condensate water flow rate generated during the air conditioning refrigeration operation, the water pump will not be able to discharge the condensate water in the water pan after a period of continuous operation. If the water pump is controlled to stop working at this time, the condensate water in the water pan will reach the preset water level within the first preset time because the water in the water pan is not gradually increased from zero. Therefore, if the water level in the water pan reaches the preset water level within the first preset time, it indicates that the water pump is dirty and blocked. The time from when the water pump stops working to when the water level reaches the preset water level is recorded as the first time, and the dirty and blocked condition of the water pump is determined based on the first time. The shorter the first time, the more serious the dirty and blocked condition of the water pump.

[0054] S13: reminding of the dirty and blocked condition of the water pump based on the first time.

[0055] It can be understood that the shorter the first time, the more serious the dirty and blocked condition of the water pump; the longer the first time, the less serious the dirty and blocked condition of the water pump. Therefore, different levels of reminding of the dirty and blocked condition of the water pump can be performed based on the first time.

[0056] For example, when the first time is long, a first-level reminding of the dirty and blocked condition of the water pump can be performed to remind the user to clean the water pan, the water pump, and the water level switch in time. When the first time is short, a second-level reminding of the dirty and blocked condition of the water pump can be performed to remind the user to clean the water pan, the water pump, and the water level switch immediately. Thus, when the water pump is dirty and blocked, the user can be reminded in time so that the user can know the dirty and blocked condition of the water pump in advance to clean it, thereby avoiding the situation that the air conditioner stops working due to the alarm reminding of the water full condition of the water pan.

[0057] That is, if the alarm reminding is performed only based on whether the water pan is full, the air conditioner will stop working, which will cause the user to be unable to continue using the air conditioner. If the dirty and blocked condition of the water pump is detected and different levels of reminding of the dirty and blocked condition of the water pump are performed based on the detected dirty and blocked condition, the user can know the dirty and blocked condition of the water pump in advance to clean it in time, and the situation that the air conditioner cannot be used due to the water full condition of the water pan can be avoided. In addition, the drainage system can be kept in a relatively clean state by cleaning in time, which reduces the impact on the health of the user and improves the service life of the water pump and the water level switch. Furthermore, since the dirty and blocked condition of the water pump needs to be detected by controlling the water pump to stop working, an intermittent working mode of stopping working for a period of time after working for a period of time is formed, which is beneficial to the discharge of foreign matters and thus prevents the water pump from being dirty and blocked.

[0058] In some embodiments, when the water level of the water pan reaches the preset water level, the water pump control method further comprises: controlling the water pump to start working, and controlling the water pump to stop working again after a second preset time.

[0059] For example, during the refrigeration operation of the air conditioner, the water pump can be controlled to work continuously for a second preset time, and then controlled to stop working, so as to detect the dirty blockage of the water pump.

[0060] When the water pump is dirty and blocked, the water discharge flow of the water pump will decrease during the continuous working of the water pump. When the decrease is less than the condensate water flow generated during the refrigeration operation of the air conditioner, the water pump will not be able to discharge the condensate water in the water pan after working for the second preset time. If the water pump is controlled to stop working at this time, since the water in the water pan is not gradually increased from zero, the condensate water in the water pan will reach the preset water level within the first preset time. At this time, in order to avoid the water level from continuing to rise and causing the water in the water pan to overflow, the water pump is controlled to work again, and then controlled to stop working again after working for the second preset time, so as to detect the dirty blockage of the water pump, and the cycle is repeated.

[0061] In this way, not only can the dirty blockage of the water pump be detected in time, but also the water pump adopts an intermittent working mode of working-stop working, which is beneficial to the discharge of foreign matters.

[0062] In some embodiments, if the water level of the water pan does not reach the preset water level within the first preset time, the water pump control method further comprises: when the time of the water pump stopping working reaches the first preset time, controlling the water pump to start working, and then controlling the water pump to stop working again after a second preset time.

[0063] For example, during the refrigeration operation of the air conditioner, the water pump can be controlled to work continuously for a second preset time, and then controlled to stop working, so as to detect the dirty blockage of the water pump.

[0064] Under normal circumstances, since the water discharge flow of the water pump is greater than the condensate water flow generated during the refrigeration operation of the air conditioner, the condensate water in the water pan will be completely discharged after the water pump works for the second preset time, and then the water pump is controlled to stop working. After the water pump stops working, the air conditioner will continue to generate condensate water, and the condensate water in the water pan will gradually increase from zero until the water pump is controlled to work again after stopping working for the first preset time, and then controlled to stop working again after working for the second preset time, and the cycle is repeated.

[0065] In this way, the water pump adopts an intermittent working mode of working-stop working, which is beneficial to the discharge of foreign matters, so that the water pump is less likely to be dirty and blocked.

[0066] In some embodiments, the first preset time and the second preset time can be obtained by the following formula (1):

[0067]

[0068] wherein m is the maximum water storage capacity of the water pan, t1 is the first preset time, V0 is the water production flow rate of the target device, such as the condensate water flow rate produced by the air conditioner during the refrigeration operation, t2 is the second preset time, i.e., the continuous working time of the water pump, V1 is the water pump drainage flow rate, and k is the preset coefficient, i.e., the safety coefficient, which ensures a certain safety margin.

[0069] In this way, by reasonably setting the first preset time and the second preset time, the water in the water pan can be promptly drained, and the dirty and clogged condition of the water pump can be promptly detected.

[0070] In some embodiments, with reference to Figure 3 the dirty and clogged condition of the water pump is reminded according to the first time, including:

[0071] S21: When the first time is greater than or equal to the first preset reminding time, first reminding information for cleaning the water pump within a first cleaning time is sent out.

[0072] S23: When the first time is less than the first preset reminding time and greater than or equal to a second preset reminding time, second reminding information for cleaning the water pump within a second cleaning time is sent out. The second preset reminding time is less than the first preset reminding time, and the second cleaning time is less than the first cleaning time.

[0073] S25: When the first time is less than the second preset reminding time, the target device is controlled to shut down, and third reminding information that the water pump needs to be repaired is sent out.

[0074] That is, the dirty and clogged condition of the water pump can be divided into three levels, and different levels correspond to different reminding information.

[0075] For example, when the first time is greater than or equal to the first preset reminding time, i.e., the first time is relatively long, the first reminding information is sent out, i.e., a first-level dirty and clogged condition of the water pump is reminded, and the reminding information is used to instruct the user to promptly clean the water pan, the water pump, and the water level switch. When the first time is less than the first preset reminding time and greater than or equal to the second preset reminding time, the second reminding information is sent out, i.e., a second-level dirty and clogged condition of the water pump is reminded, and the reminding information is used to instruct the user to immediately clean the water pan, the water pump, and the water level switch, otherwise the device is controlled to shut down. When the first time is less than the second preset reminding time, i.e., the first time is relatively short, the third reminding information is sent out, i.e., a third-level dirty and clogged condition of the water pump is reminded, and the reminding information is used to instruct the user to repair the water pump, the water level switch, etc., and the device is controlled to shut down.

[0076] Therefore, the dirty and blocked water pump is reminded in different levels according to the first time from when the water pump stops working to when the water level reaches the preset water level, so that the user can clean the water pump and other components in the water tray in time.

[0077] In some embodiments, referring to Figure 4 , the dirty and blocked water pump is reminded according to the first time, including:

[0078] S31: determining the flow decay rate of the water pump according to the first time.

[0079] It can be understood that the more serious the dirty and blocked water pump is, the smaller the drainage flow of the water pump is, the greater the flow decay rate of the water pump is, and the shorter the first time is. Therefore, the flow decay rate of the water pump can be determined according to the first time, and the dirty and blocked water pump is reminded according to the flow decay rate.

[0080] In some embodiments, the flow decay rate of the water pump can be calculated by the following formula (2):

[0081]

[0082] wherein p is the flow decay rate of the water pump, V1 is the drainage flow of the water pump, t2 is the second preset time, i.e. the continuous working time of the water pump, t 11 is the first time, and V0 is the water production flow of the target device, such as the condensate flow generated during the air conditioning refrigeration operation. As can be seen from the formula, the shorter the first time is, the greater the flow decay rate of the water pump is.

[0083] S33: reminding the dirty and blocked water pump according to the flow decay rate.

[0084] That is, the dirty and blocked water pump can be reminded according to the flow decay rate.

[0085] In some embodiments, referring to Figure 5 , the dirty and blocked water pump is reminded according to the flow decay rate, including:

[0086] S41: when the flow decay rate is greater than a first preset decay rate and less than or equal to a second preset decay rate, issuing a first reminder information for cleaning the water pump within a first cleaning time.

[0087] S43: when the flow decay rate is greater than the second preset decay rate and less than or equal to a third preset decay rate, issuing a second reminder information for cleaning the water pump within a second cleaning time. Wherein the second preset decay rate is less than the third preset decay rate, and the second cleaning time is less than the first cleaning time.

[0088] S45: when the flow decay rate is greater than the third preset decay rate, controlling the target device to stop working, and issuing a third reminder information that the water pump needs to be repaired.

[0089] That is, the water pump dirty blockage prompt can be divided into three levels, and different levels correspond to different prompt information.

[0090] For example, when the flow decay rate is greater than the first preset decay rate and less than or equal to the second preset decay rate, a first-level water pump dirty blockage prompt is performed, and the prompt information is used to instruct the user to clean the water pan, the water pump and the water level switch in time. When the flow decay rate is greater than the second preset decay rate and less than or equal to the third preset decay rate, a second-level water pump dirty blockage prompt is performed, and the prompt information is used to instruct the user to clean the water pan, the water pump and the water level switch immediately, or the control device is stopped. When the flow decay rate is greater than the third preset decay rate, that is, the first time is short, a third-level water pump dirty blockage prompt is performed, and the prompt information is used to instruct the user to maintain the water pump, the water level switch and the like, and the control device is stopped. Further, when the first prompt information, the second prompt information or the third prompt information is sent, the flow decay rate can also be displayed.

[0091] Therefore, by performing different levels of water pump dirty blockage prompts according to the flow decay rate of the water pump corresponding to the first time from when the water pump stops working to when the water level reaches the preset water level, the user can clean the water pump and other components in the water pan in time.

[0092] The foregoing water pump control method will be further described below in combination with Figure 6-9 .

[0093] For example, referring to Figure 6 , during air conditioning refrigeration operation, the water pump can be controlled to work continuously for a second preset time t2, and then stopped to perform water pump dirty blockage detection.

[0094] Under normal circumstances, because the drainage flow rate of the water pump is greater than the condensate flow rate generated during air conditioning refrigeration operation, after the water pump works continuously for the second preset time t2, the condensate in the water pan will be completely drained, and then the water pump is controlled to stop working. After the water pump stops working, the air conditioner will continue to generate condensate, and the condensate in the water pan will gradually increase from zero until the water pump stops working for the first preset time t1, and then the water pump is controlled to work again, and after working for the second preset time t2, the water pump is controlled to stop working again. Referring to Figure 6 and Figure 7 , by reasonably setting the first preset time t1, under normal circumstances, the water level in the water pan after the water pump stops working for the first preset time t1 can be made to reach h1, which is different from the preset water level h2 by △h, that is, the preset water level h2 will not be reached.

[0095] When the water pump is dirty and blocked, the water pump's drainage flow rate will decrease during the continuous operation of the water pump. When the decrease is less than the condensate flow rate generated during the air conditioner's refrigeration operation, the water pump will not be able to drain the condensate in the water pan after the second preset time t2 of continuous operation. If the water pump is controlled to stop working at this time, the condensate in the water pan will reach the preset water level h2 within the first preset time t1 because the water in the water pan is not gradually increased from zero. At this time, to avoid the water level continuing to rise and causing the water in the water pan to overflow, the water pump is controlled to work again, and the water pump is controlled to stop working again after the second preset time t2 of operation. Referring to Figure 6 and Figure 8 Because of the water pump's dirty and blockage, water in the water pan that exceeds △h cannot be drained after the second preset time t2. Therefore, after the water pump stops working for a period of time, the water in the water pan will reach the preset water level h2, and the time is less than the first preset time t1. Therefore, according to the first time t11 from when the water pump stops working to when the water level reaches the preset water level h2, the dirty and blockage of the water pump can be determined. The shorter the first time t11, the greater the flow rate attenuation rate of the water pump, and the more serious the dirty and blockage of the water pump. The test results are shown in Table 1.
