[0034] 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.

[0035] The following describes a control method for an air conditioner, a computer-readable storage medium, and an air conditioner according to embodiments of the present invention with reference to the accompanying drawings.

[0036] In one embodiment of the present invention, Figure 2 As shown, the air conditioner 200 may include an indoor unit 110, an outdoor unit 120 and a water consumption component 130. The indoor unit 110 includes an indoor heat exchanger 111 and an indoor water tank 112 disposed below the indoor heat exchanger 111 for collecting condensed water of the indoor heat exchanger 111. The outdoor unit 120 includes an outdoor heat exchanger 121 and an outdoor water tank 122 disposed below the outdoor heat exchanger 121 for collecting condensed water of the outdoor heat exchanger 121. The water consumption component 130 includes a first switching device 131, a water pump 132 and a spray head 133. The first end of the first switching device 131 extends into the indoor water tank 112 through a first pipeline, the second end of the first switching device 131 extends into the outdoor water tank 122 through a second pipeline, the third end of the first switching device 131 is connected to the inlet of the water pump 132, and the outlet of the water pump 132 is connected to the spray head 133 through a third pipeline.

[0037] Specifically, the first switching device 131 can be a three-way valve. The first switching device 131 can selectively connect the outlet of the water pump 132 with the first pipeline and the second pipeline. When the air conditioner 200 is in cooling mode, when the indoor air flows through the indoor heat exchanger 111 of the indoor unit 110 to exchange heat, the water vapor in the air condenses to form condensed water. The indoor water tank 112 can collect the condensed water dripping from the indoor heat exchanger 111. When the water level in the indoor water tank 112 is high, the water pump 132 can extract the water in the indoor water tank 112 and spray the water through the spray head 133, for example, it can be sprayed outdoors, thereby realizing water consumption. When the air conditioner 200 is in the heating mode, when the outdoor air flows through the outdoor heat exchanger 121 of the outdoor unit 120 to exchange heat, the water vapor in the air condenses to form condensed water. The outdoor water tank 122 can collect the condensed water dripping from the outdoor heat exchanger 121. Or, when heating, the outdoor unit 120 absorbs heat from the surrounding air and lowers the ambient temperature of the outdoor unit 120. When the ambient temperature drops to about 0 degrees, the moisture in the air is condensed into frost and adheres to the heat exchange plate of the outdoor unit 120. When the frost increases, it will affect the heat absorption of the outdoor unit 120, and the air conditioner 200 will start the defrosting program, generally stopping the heating program and starting the cooling program, allowing the high-temperature gas of the compressor to enter the outdoor unit 120, and the frost will be melted, and water will flow out. The outdoor water tank 122 can also collect the defrosting water, and when the water level in the outdoor water tank 122 is high, the water pump 132 can extract the water in the outdoor water tank 122 and spray the water through the spray head 133, for example, spray it outdoors, so as to realize water consumption. In addition, the water pump 132 can not only realize the extraction of water and then spray the water through the spray head 133, but also can pump water to the outdoor heat exchanger or the indoor heat exchanger for consumption, which can achieve the purpose of humidification, etc.

[0038] In addition, continue to refer to Figure 2 As shown, the water consumption component 130 may also include a second switching device 134, a first pressure relief valve 135 provided above the indoor heat exchanger 111, and a second pressure relief valve 136 provided above the outdoor heat exchanger 121, a first end of the second switching device 134 is connected to the outlet of the water pump 132, a second end of the second switching device 134 is connected to the third pipeline, a third end of the second switching device is connected to the first pressure relief valve 135 through a fourth pipeline, and a fourth end of the second switching device is connected to the second pressure relief valve 136 through a fifth pipeline.

[0039] Specifically, the second switching device 134 can be a four-way valve. The second switching device 134 can selectively connect the outlet of the water pump 132 to one or more of the third pipeline, the fourth pipeline and the fifth pipeline. When the air conditioner 200 is in cooling mode or heating mode, the condensed water in the indoor water tank 112 or the outdoor water tank 122 will be sprayed from the spray head 133. If the spray head is dirty or frozen, the condensed water will not be able to be sprayed normally from the spray head 133. Therefore, the first pressure relief valve 135 and the second pressure relief valve 136 can be automatically opened as the pipeline pressure increases, so that the condensed water in the indoor water tank 112 or the outdoor water tank 122 can be discharged through the first pressure relief valve 135 or the second pressure relief valve 136. In this way, when the spray head 133 is dirty or frozen during the operation of the air conditioner 200, it is ensured that the air conditioner 200 can still operate normally and drain water normally, which can improve the user experience.

[0040] Figure 1 FIG. 4 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present invention.

[0041] like Figure 1 As shown, the control method of the air conditioner according to the embodiment of the present invention may include the following steps:

[0042] S1, obtaining a first water level of an indoor water tank and a second water level of an outdoor water tank.

[0043] S2, controlling the first switching device and the water pump according to the first water level and / or the second water level, so that the water in the indoor water tank or the outdoor water tank is consumed by the water pump.

[0044] Specifically, when the air conditioner is in different operating modes, the amount of water stored in the indoor water tank is different from the amount of water stored in the outdoor water tank. For example, when the air conditioner is in cooling mode, when the indoor air flows through the indoor heat exchanger of the indoor unit to exchange heat, the water vapor in the air condenses to form condensed water. The indoor water tank can collect the condensed water dripping from the indoor heat exchanger. When obtaining the water level information of the indoor water tank, for example, the water level switch can be used for detection to obtain the first water level of the indoor water tank. When the air conditioner is in heating mode, when the outdoor air flows through the outdoor heat exchanger of the outdoor unit to exchange heat, the water vapor in the air condenses to form condensed water. The outdoor water tank can collect the condensed water dripping from the outdoor heat exchanger. When obtaining the water level information of the outdoor water tank, for example, the water level switch can be used for detection to obtain the second water level of the outdoor water tank. For another example, when it rains, some water drops may fall into the outdoor water tank, which can also be detected by the water level switch to obtain the second water level of the outdoor water tank.

[0045] After obtaining the first water level of the indoor water tank and the second water level of the outdoor water tank, the first switching device and the water pump can be controlled according to the first water level. For example, when the first water level reaches the set water level threshold, it means that there is a large amount of water in the indoor water tank. Therefore, the first switching device and the water pump can be controlled to consume the water in the indoor water tank through the water pump. For example, the water can be pumped out by the water pump and then sprayed outdoors through the spray head.

[0046] Alternatively, the first switching device and the water pump can also be controlled according to the second water level. When the second water level reaches the set water level threshold, it means that there is a large amount of water in the outdoor water tank. Therefore, the first switching device and the water pump can be controlled to consume the water in the outdoor water tank through the water pump. For example, the water can be pumped out by the water pump and then sprayed outdoors through the spray head.

[0047] Alternatively, the first switching device and the water pump can also be controlled according to the first water level and the second water level. When the first water level reaches the set water level threshold and the second water level also reaches the set water level threshold, it means that the amount of water in the indoor water tank is large and the amount of water in the outdoor water tank is also large. Therefore, the first switching device and the water pump can be controlled twice, so that the water in the indoor water tank is first consumed by the water pump, such as the water can be pumped out by the water pump and then sprayed outdoors through the spray head, and then the water in the outdoor water tank is consumed by the water pump, such as the water can be pumped out by the water pump and then sprayed outdoors through the spray head, or the water in the outdoor water tank is first consumed by the water pump, such as the water can be pumped out by the water pump and then sprayed outdoors through the spray head, and then the water in the indoor water tank is consumed by the water pump, such as the water can be pumped out by the water pump and then sprayed outdoors through the spray head, thereby reducing the number of pumps and the number of control valves and increasing the reliability of water consumption.

[0048] The specific working process of the anti-freezing water consumption method of the air conditioner of the present invention is described in detail below.

[0049] According to one embodiment of the present invention, the first switching device and / or the water pump are controlled according to the first water level and the second water level to consume the water in the indoor water tank or the outdoor water tank through the water pump, including: when the air conditioner is in cooling mode, if the first water level is greater than the first preset low water level, the water pump is controlled to work, and the first end and the third end of the first switching device are controlled to be connected, so that the water in the indoor water tank is consumed by the water pump; when the air conditioner is in heating mode, if the second water level is greater than the second preset low water level, the water pump is controlled to work, and the second end and the third end of the first switching device are controlled to be connected, so that the water in the outdoor water tank is consumed by the water pump. The first preset low water level and the second preset low water level can be determined according to actual conditions.

[0050] Specifically, when the air conditioner is in cooling mode, when the indoor air flows through the indoor heat exchanger of the air conditioner to exchange heat, the water vapor in the air condenses to form condensed water, which drips into the indoor water tank, and the condensed water dripping from the indoor heat exchanger is collected by the indoor water tank. Then, the first water level of the indoor water tank is obtained. For example, the first water level of the current indoor water tank can be determined by a water level switch, and the first water level is compared with the first preset low water level. When the first water level is greater than the first preset low water level, it means that some condensed water has been stored in the current indoor water tank. If the condensed water is not extracted in time, it will overflow from the indoor water tank as the water level increases. Therefore, the first end and the third end of the first switching device can be controlled to be connected, and the water pump can be controlled to work, so that the water in the indoor water tank can be extracted by the water pump and consumed by the water pump. For example, after the water is extracted by the water pump, the water is sprayed to the outside through the spray head, thereby completing the consumption of the condensed water in the indoor water tank.

[0051] When the air conditioner is in heating mode, when outdoor air flows through the outdoor heat exchanger of the air conditioner to exchange heat, water vapor in the air condenses to form condensed water, which drips into the outdoor water tank, and the condensed water dripping from the outdoor heat exchanger is collected by the outdoor water tank. Then the second water level of the outdoor water tank is obtained. For example, the second water level of the current outdoor water tank can be determined by a water level switch, and the second water level is compared with the second preset low water level. When the second water level is greater than the second preset low water level, it means that some condensed water has been stored in the current outdoor water tank. If the condensed water is not extracted in time, it will overflow from the outdoor water tank as the water level increases. Or, in a low-level environment, the water in the outdoor water tank is prone to freezing, etc., and the water in the outdoor water tank cannot be consumed normally. Therefore, the second end and the third end of the first switching device can be controlled to be connected, and the water pump can be controlled to work, so that the water in the outdoor water tank can be extracted by the water pump and consumed by the water pump. For example, after the water is extracted by the water pump, the water is sprayed outdoors through the spray head, thereby completing the consumption of the condensed water in the outdoor water tank.

[0052] According to one embodiment of the present invention, the water consumption component also includes a second switching device, a first pressure relief valve arranged above the indoor heat exchanger and a second pressure relief valve arranged above the outdoor heat exchanger, the first end of the second switching device is connected to the outlet of the water pump, the second end of the second switching device is connected to the third pipeline, the third end of the second switching device is connected to the first pressure relief valve through a fourth pipeline, and the fourth end of the second switching device is connected to the second pressure relief valve through a fifth pipeline. The method also includes: when the air conditioner is in cooling mode and the indoor water tank has a drainage demand, the first end of the second switching device is controlled to connect the second end and the fourth end, so as to release pressure through the second pressure relief valve when the spray head is blocked; when the air conditioner is in heating mode and the outdoor water tank has a drainage demand, the first end of the second switching device is controlled to connect the second end and the third end, so as to release pressure through the first pressure relief valve when the spray head is blocked.

[0053] The spray head with high-pressure atomization can atomize the condensed water for consumption. However, the nozzle has a small caliber and there is a risk of dirt blockage and freezing blockage. Ultimately, the user cannot clear the pipeline in time, which leads to problems such as failure to start the machine, overflow, and high-pressure expansion pipe burst. Therefore, in order to prevent the spray head from being blocked by dirt or freezing of the spray head due to the low outdoor ambient temperature during the operation of the air conditioner, when the condensed water in the indoor water tank or the outdoor water tank cannot be sprayed through the spray head, a second switching device and a first pressure relief valve arranged on the indoor heat exchanger and a second pressure relief valve arranged above the outdoor heat exchanger are added in the present invention to ensure the normal discharge of the condensed water.

[0054] Specifically, the opening and closing of the first pressure relief valve and the second pressure relief valve are controlled by the water pressure in the pipeline. When the spray head is blocked by dirt or freezing, the increase in water pressure will cause the water pipe to rupture. The first pressure relief valve and the second pressure relief valve can relieve pressure and drain water in time. That is, when the air conditioner is in cooling mode and the indoor water tank has a drainage demand (that is, the first water level is greater than the first preset low water level), the first end of the second switching device can be controlled to connect the second end and the fourth end, and at this time the first end and the third end of the first switching device are connected. Therefore, when the spray head is blocked, the condensed water that was originally sprayed through the spray head after the water pump draws water from the indoor water tank becomes the condensed water that flows through the fifth pipeline through the second pressure relief valve. As the pressure in the pipeline rises, the condensed water is discharged by opening the second pressure relief valve. When the air conditioner is in heating mode and the outdoor water tank has a drainage demand (i.e., the second water level is greater than the second preset low water level), the first end of the second switching device can be controlled to connect the second end and the third end, and at this time the second end and the third end of the first switching device are connected, so that when the spray head is blocked, the condensed water that was originally sprayed through the spray head after the water pump draws water from the outdoor water tank changes to flow through the fourth pipeline through the first pressure relief valve, and as the pressure of the pipeline rises, the first pressure relief valve is opened to discharge the condensed water.

[0055] According to one embodiment of the present invention, the method also includes: after the pressure is released through the second pressure relief valve, if the second water level is greater than the second preset low water level, the second end and the third end of the first switching device are controlled to be connected, and the first end and the fourth end of the second switching device are controlled to be connected, so that the water in the outdoor water tank is consumed through the outdoor heat exchanger; after the pressure is released through the first pressure relief valve, if the first water level is greater than the first preset low water level, the first end and the third end of the first switching device are controlled to be connected, and the first end and the third end of the second switching device are controlled to be connected, so that the water in the indoor water tank is consumed through the indoor heat exchanger.

[0056] Specifically, if Figure 3As shown, after the pressure is released through the second pressure relief valve 136, the condensed water can drip from the second pressure relief valve 136 onto the outdoor heat exchanger 121, and the unconsumed condensed water of the outdoor heat exchanger 121 will continue to drip into the outdoor water tank 122, thereby, the second water level in the second water tank 122 can be judged, and when the second water level is greater than the second preset low water level, the second end and the third end of the first switching device 131 can be controlled to be connected, and the first end and the fourth end of the second switching device 134 can be controlled to be connected, so that the water in the outdoor water tank 122 can be passed through The water pump 132 extracts and flows to the second pressure relief valve 136 through the second switching device 134. When the condensed water flows out from the second pressure relief valve 136, it can drip on the outdoor heat exchanger 121, so that the water in the outdoor water tank 122 can be consumed through the outdoor heat exchanger 121. The condensed water can be consumed by spraying the outdoor heat exchanger 121, that is, the condensed water is evaporated through the outdoor heat exchanger 121 and the water is blown out of the room through the fan. The heat exchange effect of the outdoor heat exchanger 121 can also be improved to keep the air conditioner running normally.

[0057] like Figure 4 As shown, after the pressure is released through the first pressure relief valve 135, the condensed water can drip from the first pressure relief valve 135 onto the indoor heat exchanger 111, and the unconsumed condensed water of the indoor heat exchanger 111 will continue to drip into the indoor water tank 112, thereby, the first water level in the first water tank 112 can be judged, and when the first water level is greater than the first preset low water level, the first end and the third end of the first switching device 131 can be controlled to be connected, and the first end and the third end of the second switching device 134 can be controlled to be connected, so that the indoor The water in the water tank 112 is pumped by the water pump 132 and flows to the first pressure relief valve 135 through the second switching device 134. When the condensed water flows out from the first pressure relief valve 135, it can drip on the indoor heat exchanger 111, so that the water in the indoor water tank 112 can be consumed through the indoor heat exchanger 111, that is, the condensed water can be consumed by spraying the indoor heat exchanger 111, the indoor space can be humidified, and the heat exchange effect of the indoor heat exchanger 111 can be improved to keep the air conditioner operating normally.

[0058] In summary, under the control method of the present invention, the high pressure caused by dirty blockage or frozen blockage can be discharged through two pressure relief valves to avoid pipe burst. At the same time, the discharged water is used to spray the heat exchanger for consumption, so that the air conditioner can remind the user to replace the spray head and maintain the normal operation of the air conditioner, avoiding the poor user experience caused by protection shutdown due to dirty blockage or frozen blockage and inability to drain water.

[0059] According to one embodiment of the present invention, when the water in the indoor water tank is consumed through the indoor heat exchanger, the method also includes: if the second water level is greater than the second preset low water level, controlling the second end and the third end of the first switching device to be connected, and controlling the first end and the third end of the second switching device to be connected, so that the water in the outdoor water tank is consumed through the indoor heat exchanger.

[0060] Specifically, if Figure 5 As shown, when the water in the indoor water tank 112 is consumed through the indoor heat exchanger 111, since the air conditioner is in heating mode, the condensed water will continue to gather in the outdoor water tank 122. Therefore, the second water level of the outdoor water tank 122 can be judged. When the second water level is greater than the second preset low water level, it means that there is a lot of condensed water in the outdoor water tank 122. The second end and the third end of the first switching device 131 can be controlled to be connected, and the first end and the third end of the second switching device 134 can be controlled to be connected, so that the condensed water in the outdoor water tank 122 can be extracted and flow to the first pressure relief valve 135 through the second switching device 134, and drip to the indoor heat exchanger 111 through the first pressure relief valve 135, so that the condensed water is consumed through the indoor heat exchanger 111, which can ensure that the indoor environment is humidified when the air conditioner is in heating operation, thereby improving the user experience.

[0061] According to one embodiment of the present invention, after the water in the outdoor water tank is consumed by the indoor heat exchanger, the method also includes: after a delay of a first preset time, controlling the first end and the third end of the first switching device to be connected again, and controlling the first end and the third end of the second switching device to be connected, so that the water in the indoor water tank is consumed by the indoor heat exchanger.

[0062] Specifically, if Figure 4 As shown, after the water in the outdoor water tank 122 is consumed through the indoor heat exchanger 111, after a first preset time, the water pump 132 can pump all the water in the outdoor water tank 122 into the indoor water tank 112, and then the first end and the third end of the first switching device 131 can be controlled to be connected again, and the first end and the third end of the second switching device 132 can be controlled to be connected, so that the water in the indoor water tank 112 can be pumped through the water pump 132 and dripped into the indoor heat exchanger 111 through the first pressure relief valve 135, so that the water in the indoor water tank 112 can continue to be consumed through the indoor heat exchanger 111, which can ensure that the indoor environment is humidified when the air conditioner is in heating operation, thereby improving the user experience.

[0063] According to one embodiment of the present invention, when the water of the indoor water tank or the outdoor water tank is consumed by a water pump, the method also includes: obtaining a first spray time; when the first spray time reaches a first preset spray time, controlling the first end and the third end of the first switching device to be connected, and controlling the first end and the second end of the second switching device to be connected, so as to perform anti-freezing protection on the spray head; wherein the first preset spray time is less than the second preset spray time to complete the spraying of the water of the outdoor water tank.

[0064] Specifically, when the air conditioner is in heating mode and the water in the outdoor water tank is consumed by the water pump, the current spraying time, i.e., the first spraying time, is obtained. After the spray head sprays the first spraying time, the condensed water in the outdoor water tank will be reduced to a thin water film. At this time, although the water pump is continuously turned on, a small amount of droplets will be carried into the pipeline. When the droplets remain in the spray head, they may freeze and expand to cause blockage. Therefore, in order to avoid this freezing and blockage phenomenon, Figure 6 As shown, when the first spraying time reaches the first preset spraying time, the first end and the third end of the first switching device 131 are controlled to be connected, and the first end and the second end of the second switching device 134 are controlled to be connected, so that the water pump 132 draws air in the indoor water tank 112, and continuously takes away the residual droplets in the pipeline through the air. When there are no residual droplets in the pipeline, even in a low temperature environment, it will not cause the spray head or the pipeline to be frozen, thereby protecting the spray head from freezing.

[0065] It should be noted that the first preset injection time is shorter than the second preset injection time for completing the injection of water from the outdoor water tank, which ensures that the water pump will not extract all the condensed water in the outdoor water tank within the first preset injection time. Since the water pump's suction port makes a louder noise when absorbing water vapor when the amount of water is small, a portion of the condensed water can be left in the outdoor water tank, so that when the water pump is pumping, no water vapor mixture is extracted, thereby reducing the noise problem during the operation of the water pump. That is, only when the shutdown command is received will all the condensed water in the outdoor water tank be extracted and injected, which can reduce the number of times the water pump absorbs water vapor.

[0066] According to one embodiment of the present invention, when the water in the indoor water tank or the outdoor water tank is consumed by the water pump, the method further includes: in response to a shutdown instruction, when the first spraying time reaches the second preset spraying time, controlling the water pump to stop working.

[0067] Specifically, when the water in the outdoor water tank is consumed by the water pump, a shutdown command can be responded to. For example, the air conditioner can be shut down by controlling the air conditioner remote control, or a shutdown command can be sent through a mobile device connected to the air conditioner, such as a mobile phone, a tablet, etc. And it is determined whether the first spray time reaches the second preset spray time. When the first spray time does not reach the second preset spray time, the water pump can be controlled to continue working to consume the condensed water in the outdoor water tank through the water pump; when the first spray time reaches the second preset spray time, it means that the current water pump has consumed the water in the outdoor water tank, such as spraying it to the outdoors through the spray head, and there is no more condensed water left in the outdoor water tank, so the water pump can be controlled to stop working.

[0068] According to one embodiment of the present invention, when the water in the indoor water tank or the outdoor water tank is consumed by a water pump, the method also includes: obtaining a second spraying time; when the second spraying time reaches a third preset spraying time, controlling the water pump to stop working; wherein the third preset spraying time is less than a fourth preset spraying time to complete the spraying of the water in the indoor water tank.

[0069] Specifically, when the air conditioner is operating in cooling mode, when the water in the indoor water tank is consumed by the water pump, the current injection time, i.e., the second injection time, is obtained, and it is determined whether the second injection time has reached the third preset injection time. When the second injection time has not reached the third preset injection time, the condensed water in the indoor water tank can continue to be pumped out by the water pump and consumed by the water pump. When the second injection time reaches the third preset injection time, the water pump can be controlled to stop working and no longer pump the condensed water in the indoor water tank.

[0070] It should be noted that the third preset injection time is shorter than the fourth preset injection time for completing the injection of water from the indoor water tank, i.e., it is ensured that within the third preset injection time, the water pump will not extract all the condensed water in the indoor water tank. Since the suction port of the water pump makes a louder noise when absorbing water vapor when the amount of water is small, a portion of the condensed water can be left in the indoor water tank, so that when the water pump is pumping, no water vapor mixture will be extracted, thereby reducing the noise problem during the operation of the water pump. That is, only when the shutdown command is received, the condensed water in the indoor water tank will be completely extracted and sprayed outdoors, which can reduce the number of times the water pump absorbs water vapor.

[0071] According to one embodiment of the present invention, when the water in the indoor water tank or the outdoor water tank is consumed by the water pump, the method further includes: in response to a shutdown instruction, when the second spraying time reaches a fourth preset spraying time, controlling the water pump to stop working.

[0072] Specifically, when the water in the indoor water tank is consumed by the water pump, a shutdown command can be responded to, for example, the air conditioner can be shut down by controlling the air conditioner remote control, or a shutdown command can be sent through a mobile device connected to the air conditioner, such as a mobile phone, a tablet, etc. And it is determined whether the second injection time reaches the fourth preset injection time. When the second injection time does not reach the fourth preset injection time, the water pump can be controlled to continue working to consume the condensed water in the indoor water tank through the water pump; when the second injection time reaches the fourth preset injection time, it means that the current water pump has consumed the water in the indoor water tank, such as spraying it to the outdoors through the spray head, and there is no more condensed water left in the indoor water tank, so the water pump can be controlled to stop working.

[0073] It should be noted that the air conditioner in the present invention is not limited to a window air conditioner, but is applicable to other air conditioning systems and non-air conditioning systems that require drainage.

[0074] In summary, according to the control method of the air conditioner of the embodiment of the present invention, the first water level of the indoor water tank and the second water level of the outdoor water tank are first obtained, and then the first switching device and the water pump are controlled according to the first water level and / or the second water level to consume the water in the indoor water tank or the outdoor water tank through the water pump. Therefore, the method can reduce the number of pumps and the number of control valves, and increase the reliability of water consumption.
