[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The following is attached to the instruction manual Figure 1 -Attached Figure 6And specific implementation methods are described in detail for the control method, device and storage medium, controller and air conditioner of the air conditioner in the embodiment of the present invention.

[0035] The air conditioner in the embodiment of the present invention may include an indoor unit and an outdoor unit. The indoor unit is provided with an indoor water storage structure 1 and a spray pump 4, and the outdoor unit is provided with an outdoor water storage structure 2. The indoor water storage structure 1 is connected to the outdoor water storage structure 2 through a water pipe and a water pump 3. Figure 1 .

[0036] In order to prevent the condensation water generated in the outdoor unit of the heating and cooling air conditioner when heating in a cold environment, the water splashing and freezing damage to the fan blades due to insufficient water pumping on the outdoor side fan blades, and the freezing and blockage of the pump body of the outdoor unit during spraying, the embodiment of the present invention is provided with a water pipe and a water pump 3, and the indoor water storage structure 1 is connected with the outdoor water storage structure 2, so that the condensation water in the outdoor water storage structure 2 is pumped into the indoor water storage structure 1 by controlling the water pump 4, and the condensation water in the indoor water storage structure 1 is uniformly consumed, so as to achieve the purpose of not needing to drain water.

[0037] In the embodiment of the present invention, the spray pump 4 is connected to the atomizing nozzle 5 provided at the outdoor unit to atomize and spray the condensed water in the indoor water storage structure to the outdoors.

[0038] Figure 2 FIG. 1 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present invention. Figure 2 As shown, the control method of the air conditioner may include:

[0039] S101, detecting the water storage conditions of the indoor water storage structure and the outdoor water storage structure respectively;

[0040] S102, if it is detected that the condensed water in the indoor water storage structure needs to be discharged, the spray pump is controlled to work so as to spray the condensed water in the indoor water storage structure to the outside in atomized form;

[0041] S103: If it is detected that the condensed water in the outdoor water storage structure needs to be discharged, the water pump is controlled to operate so as to pump the condensed water in the outdoor water storage structure to the indoor water storage structure.

[0042] Specifically, after the air conditioner is turned on, the water storage conditions of the indoor water storage structure and the outdoor water storage structure are detected respectively to detect whether the condensed water in the indoor water storage structure and the outdoor water storage structure needs to be discharged. When it is detected that the condensed water in the indoor water storage structure needs to be discharged, the spray pump is controlled to work so as to spray and atomize the condensed water in the indoor water storage structure to the outside. When it is detected that the condensed water in the outdoor water storage structure needs to be discharged, the pumping pump is controlled to work so as to pump the condensed water in the outdoor water storage structure to the indoor water storage structure.

[0043] It should be noted that the above detection and control process is not affected by the specific mode in which the air conditioner is turned on. That is, there is no need to specify a specific mode, such as air supply mode, cooling mode or heating mode. The above detection and control process is effective for all modes to ensure that water system protection is prioritized.

[0044] When controlling the spray pump to work, the embodiment of the present invention controls the spray pump to run a first preset number of times to reduce the water level of condensed water in the indoor water storage structure to a safe water level area. The spray pump is turned on for a first time and turned off for a second time each time it runs. Exemplarily, the spray pump is turned on for 50 seconds and turned off for 10 seconds each time it runs.

[0045] In the embodiment of the present invention, when controlling the operation of the water pump, the water pump is controlled to operate for a second preset number of times to reduce the water level of the condensed water in the outdoor water storage structure to a safe water level area. The water pump is turned on for a third time each time it operates and is turned off for a fourth time. Exemplarily, the water pump is turned on for 50 seconds and turned off for 10 seconds each time it operates.

[0046] It should be noted that the opening and closing time of each operation of the spray pump and the water pump is related to the flow rate of the pump and the length of the water pipe. The opening and closing time of each operation of the spray pump and the water pump can be set according to the flow rate of the pump and the length of the water pipe.

[0047] It should be noted that the first preset number of times and the second preset number of times are related to the capacity of the indoor water storage structure and the outdoor water storage structure and the operation of the spray pump and the water pump. The first preset number of times can be determined according to the capacity of the indoor water storage structure and the operation of the spray pump. The second preset number of times can be determined according to the capacity of the outdoor water storage structure and the operation of the water pump.

[0048] In one embodiment of the present invention, the indoor water storage structure is provided with an indoor water level switch 6, and the water storage condition of the indoor water storage structure is characterized by the alarm condition of the indoor water level switch 6 and the working time of the spray pump;

[0049] Among them, if the indoor water level switch alarms, or the working time of the spray pump does not exceed the first preset time, it is determined that the condensed water in the indoor water storage structure needs to be discharged, and the indoor water level switch alarms when the water level of the indoor water storage structure exceeds the first preset water level.

[0050] In the embodiment of the present invention, an indoor water level switch 6 is provided in the indoor water storage structure to detect whether the water level of condensed water in the indoor water storage structure exceeds a first preset water level.

[0051] In this embodiment, the indoor water level switch alarm indicates that the water level of the condensed water in the indoor water storage structure has reached the first preset water level, and the condensed water in the indoor water storage structure needs to be discharged. When the indoor water level switch alarms, the spray pump is controlled to run for the first preset number of times to reduce the water level of the condensed water in the indoor water storage structure to a safe water level area. Therefore, when the working time of the spray pump does not exceed the first preset time, it can also be said that the water level of the condensed water in the indoor water storage structure is high and has not reached the safe water level area, and the condensed water in the indoor water storage structure needs to be discharged.

[0052] In one embodiment of the present invention, Figure 3 As shown, if it is detected that the condensed water in the indoor water storage structure needs to be discharged, the spray pump is controlled to work, which may include:

[0053] If the indoor water level switch alarm is detected, the spray pump is controlled to work for the first preset number of times;

[0054] If it is detected that the working time of the spray pump does not exceed the first preset time, the spray pump is controlled to continue working until the first preset time is reached.

[0055] Specifically, when discharging the condensed water in the indoor water storage structure, it is detected whether the indoor water level switch alarms. When the indoor water level switch alarm is detected, the spray pump is controlled to work for a first preset number of times to reduce the water level of the condensed water in the indoor water storage structure to a safe water level area. In the process of controlling the operation of the spray pump, it is detected whether the working time of the spray pump exceeds the first preset time. If it is detected that the working time of the spray pump does not exceed the first preset time, it means that the water level of the condensed water in the indoor water storage structure is high, and the spray pump needs to be controlled to continue working until the working time of the spray pump reaches the first preset time.

[0056] In one embodiment of the present invention, the outdoor water storage structure is provided with an outdoor water level switch 7, and the water storage condition of the outdoor water storage structure is characterized by the alarm condition of the outdoor water level switch 7 and the working time of the water pump;

[0057] Among them, if the outdoor water level switch alarms, or the working time of the water pump does not exceed the second preset time, it is determined that the condensed water in the outdoor water storage structure needs to be discharged, and the outdoor water level switch alarms when the water level of the outdoor water storage structure exceeds the second preset water level.

[0058] In the embodiment of the present invention, an outdoor water level switch 7 is provided in the outdoor water storage structure to detect whether the water level of condensed water in the outdoor water storage structure exceeds a second preset water level.

[0059] In this embodiment, the outdoor water level switch alarm indicates that the water level of the condensed water in the outdoor water storage structure exceeds the second preset water level, and the condensed water in the outdoor water storage structure needs to be discharged. When the outdoor water level switch alarms, the pump is controlled to run the second preset number of times to reduce the water level of the condensed water in the outdoor water storage structure to a safe water level area. Therefore, when the working time of the pump does not exceed the second preset time, it can also indicate that the water level of the condensed water in the outdoor water storage structure is high and has not reached the safe water level area, and the condensed water in the outdoor water storage structure needs to be discharged.

[0060] In one embodiment of the present invention, Figure 3 As shown, if it is detected that the condensed water in the outdoor water storage structure needs to be discharged, the water pump is controlled to work, which may include:

[0061] If an outdoor water level switch alarm is detected, the water pump is controlled to work for a second preset number of times;

[0062] If it is detected that the working time of the water pump does not exceed the second preset time, the water pump is controlled to continue working until the second preset time is reached.

[0063] Specifically, when discharging condensed water in the outdoor water storage structure, it is detected whether the outdoor water level switch alarms. When the outdoor water level switch alarm is detected, the water pump is controlled to work for a second preset number of times to reduce the water level of the condensed water in the outdoor water storage structure to a safe water level area. In the process of controlling the operation of the water pump, it is detected whether the working time of the water pump exceeds the second preset time. If it is detected that the working time of the water pump does not exceed the second preset time, it means that the water level of the condensed water in the outdoor water storage structure is high, and the water pump needs to be controlled to continue working until the working time of the water pump reaches the second preset time.

[0064] As a specific embodiment, the controller detects the water storage conditions of the indoor water storage structure and the outdoor water storage structure every 60 seconds. When the controller detects that the condensed water in the indoor water storage structure needs to be discharged, the spray pump is controlled to run 5 times, wherein the spray pump is turned on for 50 seconds and turned off for 10 seconds each time it runs. And when the controller detects that the condensed water in the outdoor water storage structure needs to be discharged, the pump is controlled to run 10 times, wherein the pump is turned on for 50 seconds and turned off for 10 seconds each time it runs:

[0065] If the indoor water level switch alarm is detected at time t0, the spray pump is controlled to work 5 times, and the spray pump works for 5*60s. In these 300s, the water storage situation of the indoor water storage structure is still detected every 60s. If the indoor water level switch alarm is not detected in these 300s, the spray pump still works and needs to be controlled to work until 300s is reached; if the outdoor water level switch alarm is detected in 300s, it is ignored, or the outdoor water level switch alarm is not detected when the spray pump is working.

[0066] If the outdoor water level switch alarm is detected at time t1, the pump is controlled to work 10 times, and the pump works for 10*60 seconds. During the 600s, the water storage situation of the outdoor water storage structure is still detected every 60s. If the indoor water level switch alarm is detected at t1+60s, the pump is controlled to shut down and the spray pump is controlled to work 5 times (i.e., the above steps of detecting the indoor water level switch alarm at time t0 and controlling the spray pump to work 5 times are executed); if there is no alarm within 600s, the pump needs to be controlled to work until 600s is reached.

[0067] It should be noted that after the alarm controls the pump to work, under normal circumstances, the same alarm should not be detected in the next detection cycle. For example, if the indoor water level switch alarm is detected at time t0, the spray pump is controlled to work. If it is detected again within 300s, theoretically, there should be no alarm because the water is pumped outdoors, and the spray pump stops working after 300s. If there is a fault, the alarm may be detected multiple times in a row within 300s, and the spray pump will continue to work. The number of operations is the number of operations before the last alarm was detected plus 5 times.

[0068] In one embodiment of the present invention, Figure 3 As shown, the control method of the air conditioner may further include:

[0069] If the indoor water level switch alarm is detected for the third consecutive preset time, or if it is detected that the spray pump has run for more than the third preset number of times, the spray pump is controlled to stop working and a first fault reminder message is issued, wherein the third preset number of times is greater than the first preset number of times, and the third preset time is greater than the first preset time.

[0070] At this time, if the air conditioner includes a water pump, the water pump stops working to avoid pumping condensed water in the outdoor water storage structure into the indoor water storage structure, thereby causing the water level in the indoor water storage structure to rise and causing the indoor water level switch to alarm.

[0071] If the air conditioner includes a humidification pump, the humidification pump stops working, thereby preventing the water in the indoor water storage structure from being evaporated and consumed, resulting in inaccurate detection of the spray pump.

[0072] Specifically, when the indoor water level switch alarm is detected, the spray pump is controlled to work for the first preset number of times (first preset time). The spray pump works for the first preset time to reduce the water level of the condensed water in the indoor water storage structure to a safe water level area. Under normal circumstances, the indoor water level switch will not alarm at the first preset time. If the indoor water level switch alarm is detected for the third consecutive preset time, it means that the spray pump water system is blocked. At this time, the spray pump is controlled to stop working and a first fault reminder message is issued to remind the staff to inspect and repair the spray pump water system.

[0073] In addition, under normal circumstances, after the indoor water level switch alarms, the spray pump works for the first preset number of times. If it is detected that the spray pump has run for more than the third preset number of times, it indicates that the spray pump water system is blocked. At this time, the spray pump is controlled to stop working and a first fault reminder message is issued to remind the staff to inspect and repair the spray pump water system.

[0074] In one embodiment of the present invention, after the pump is controlled to operate for a second preset time, the condensed water in the outdoor water storage structure has been discharged to the indoor water storage structure by the pump. Therefore, after the pump is controlled to operate for a second preset time, it can be detected whether the indoor water level switch alarms.

[0075] If the indoor water level switch alarms, it means that the water level of the condensed water in the indoor water storage structure has reached the first preset water level, and the condensed water in the indoor water storage structure needs to be discharged. The spray pump can be controlled to run the first preset number of times to discharge the condensed water in the indoor water storage structure. If the indoor water level switch does not alarm, it means that the water level of the condensed water in the indoor water storage structure has not reached the first preset water level, and the condensed water in the indoor water storage structure does not need to be discharged temporarily.

[0076] After the water pump is controlled to run outdoors for the second preset number of times, if the indoor water level switch does not alarm, it is possible to detect whether the outdoor water pump switch alarms. If the outdoor water pump switch does not alarm, it should be noted that since the water pump has been controlled to run for the second preset number of times, under normal circumstances, the water level of the condensed water in the outdoor water storage structure should not exceed the second preset water level, and the condensed water in the outdoor water storage structure does not need to be discharged temporarily. Therefore, if the outdoor water pump switch does not alarm, the spray pump can be controlled to run for the first preset number of times to discharge the condensed water in the indoor water storage structure. If the outdoor water pump switch alarms, since the water pump has been controlled to run for the second preset number of times, under normal circumstances, the indoor water level switch should not alarm, but the outdoor water pump switch alarms, it means that the drainage of the outdoor water storage structure may be abnormal.

[0077] In one embodiment of the present invention, Figure 3 As shown, the control method of the air conditioner may further include:

[0078] If the outdoor water level switch alarm is detected for the fourth consecutive preset time, or if it is detected that the water pump has run for more than the fourth preset number of times, the water pump is controlled to stop working and a second fault reminder message is issued, wherein the fourth preset number of times is greater than the second preset number of times and the fourth preset time is greater than the second preset time.

[0079] Specifically, when the outdoor water level switch alarm is detected, the water pump is controlled to work for the second preset number of times (second preset time). The water pump works for the second preset number of times (second preset time) to reduce the water level of the condensed water in the outdoor water storage structure to a safe water level area. Under normal circumstances, the outdoor water level switch will not alarm at the second preset time. If the outdoor water level switch alarm is detected for the fourth consecutive preset time, it means that the water system of the water pump is blocked. At this time, the water pump is controlled to stop working, and a second fault reminder message is issued to remind the staff to check and repair the water system of the water pump.

[0080] In addition, under normal circumstances, after the outdoor water level switch alarms, the water pump works for the second preset number of times. If it is detected that the spray pump has run for more than the third preset number of times, it means that the spray pump water system is blocked. At this time, the water pump is controlled to stop working and a second fault reminder message is issued to remind the staff to check and repair the water pump water system.

[0081] In one embodiment of the present invention, the indoor unit is further provided with a humidifying pump, and the control method of the air conditioner further comprises:

[0082] In response to a humidification instruction, detecting the working status of a spray pump and a water pump;

[0083] If the spray pump and the water pump are both in a stopped state, the humidification pump is controlled to start, so as to utilize the condensed water in the indoor water storage structure to humidify the room.

[0084] Specifically, when a humidification instruction is received, the working status of the spray pump and the water pump is detected. If both the spray pump and the water pump are in a stopped working state, the humidification pump is controlled to start to provide humidification for the user. When the humidification pump is turned on, the condensed water in the indoor water storage structure can be consumed while humidifying the room. If the indoor water level switch does not alarm when the humidification pump is turned on, it means that the water level of the condensed water in the indoor water storage structure is in the safe water level area. At this time, drainage is no longer required, and the water pump and the spray pump can stop operating.

[0085] It should be noted that the humidifier pump can use the condensed water in the indoor water storage structure to humidify the room, and can also use the condensed water in the outdoor water storage structure to humidify the room. If the outdoor water level switch does not alarm when the humidifier pump is turned on, it means that the water level of the condensed water in the outdoor water storage structure is in the safe water level area. At this time, there is no need to drain the water, and the pump and spray pump can stop operating.

[0086] In one embodiment of the present invention, the control method of the air conditioner further comprises: during the operation of the spray pump, controlling the water pump and the humidification pump to stop working.

[0087] Specifically, when the spray pump is controlled to work, the water pump and the humidification pump are synchronously controlled to be turned off. This is mainly because the whole machine current is at its peak value and to avoid the whole machine current being too high. Therefore, during the operation time of the spray pump, the water pump and the humidification pump are controlled to stop working.

[0088] In one embodiment of the present invention, during the process of controlling the operation of the water pump, the spray pump and the humidification pump are synchronously controlled to be turned off. This is mainly because the whole machine current is at its peak value and to avoid the whole machine current being too high. Therefore, during the operation time of the water pump, the spray pump and the humidification pump are controlled to stop working.

[0089] In an embodiment of the present invention, in response to a shutdown instruction, the spray pump will perform a spray operation, mainly to dry any residual water in the spray pump, thereby avoiding the risk of ice blockage in winter.

[0090] It should be noted that the shutdown instruction may be a shutdown instruction issued by a user, or a shutdown instruction generated after a fault is reported. The shutdown instruction generated after a fault is reported includes: generating a shutdown instruction when a first fault reminder message is issued, generating a shutdown instruction when a second fault reminder message is issued, or any one or more of the shutdown instructions.
