[0005] In some embodiments, the air conditioner includes a second water pump and a second water level sensor. The second water pump is used to draw water from the water storage device for humidification, and the second water level sensor is used to detect whether the water level in the water storage device is below a second threshold, wherein the second threshold is less than a first threshold. The control method includes: turning off the second water pump when the second water level sensor detects that the water level in the water storage device is below the second threshold.

[0006] In some embodiments, the control method includes: when the first water level sensor detects that the water in the water storage device is higher than the first threshold, starting the second water pump for a first predetermined time and then starting the first water pump.

[0007] In some embodiments, the control method includes determining the first predetermined duration based on the flow rate of the second water pump, the capacity of the water storage device, and the humidification requirement.

[0008] In some embodiments, the control method includes: when the second water level sensor detects that the water in the water storage device is lower than the second threshold, the second water pump is turned on after the first water pump has been operating for a second predetermined period of time.

[0009] In some embodiments, the control method includes: acquiring a time difference when the humidification mode of the air conditioner is turned on, the time difference being the difference between the current turn-on time and the previous turn-on time; and activating a smart cleaning function to clean the evaporator of the air conditioner when the time difference is greater than a preset time difference.

[0010] In some embodiments, when the humidification mode of the air conditioner is turned on, the degree of dirt clogging of the filter screen is obtained; if the degree of dirt clogging is greater than a preset degree of dirt clogging, the filter screen is cleaned.

[0011] In some embodiments, the air conditioner includes a second water level sensor for detecting whether the water level in the water storage device is below a second threshold.

[0012] An air conditioner according to an embodiment of this application includes a water receiving tray, a water storage device, a pipeline connecting the water receiving tray and the water storage device, a first water pump for pumping water from the water receiving tray to the water storage device through the pipeline, a filter installed in the pipeline, a first water level sensor, and a processor.

[0014] The control method, air conditioner, and computer-readable storage medium of this application embodiment can shut down the first water pump when the water level in the water storage device is higher than the first threshold. This avoids the first water pump continuously drawing condensate, which would cause the filter to filter condensate for an extended period of time, thus extending the filter's service life.

[0015] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

Detailed Implementation

[0017] The embodiments of this application are described in detail below. 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 are only used to explain this application, and should not be construed as limiting this application.

[0018] Please refer to the following: Figure 1 , Figure 2 and Figure 3 This application provides a control method for an air conditioner 100. The air conditioner 100 includes a water receiving tray 10, a water storage device 20, a pipeline connecting the water receiving tray 10 and the water storage device 20, a first water pump 30 for pumping water from the water receiving tray 10 to the water storage device 20 through the pipeline, a filter 40 installed in the pipeline, and a first water level sensor 50. The first water level sensor 50 is used to detect whether the water level in the water storage device 20 is higher than a first threshold. The control method includes: Step 01: When the first water level sensor 50 detects that the water in the water storage device 20 is higher than the first threshold, the first water pump 30 is turned off.

[0019] Please refer to it again. Figure 2 and Figure 3 This application also provides an air conditioner 100, and the control method of this application can be implemented by the air conditioner 100 of this application. The air conditioner 100 includes a water receiving tray 10, a water storage device 20, a pipeline connecting the water receiving tray 10 and the water storage device 20, a first water pump 30 for pumping water from the water receiving tray 10 to the water storage device 20 through the pipeline, a filter 40 installed in the pipeline, a first water level sensor 50, and a processor 80. The first water level sensor 50 is used to detect whether the water in the water storage device 20 is higher than a first threshold. Step 01 can be implemented by the processor 80, that is, the processor 80 is used to: shut off the first water pump 30 when the first water level sensor 50 detects that the water in the water storage device 20 is higher than the first threshold.

[0020] The control method and air conditioner 100 of this application embodiment can shut down the first water pump 30 when the water level in the water storage device 20 is higher than a first threshold. This avoids the first water pump 30 continuously drawing condensate, which would cause the filter 40 to filter condensate for an extended period of time, thus extending the service life of the filter 40.

[0021] Specifically, the air conditioner 100 includes an evaporator and a drip tray 10. The drip tray 10 can be located below the evaporator and can collect condensate flowing down the surface of the evaporator. The first water pump 30 can extract the condensate from the drip tray 10. Under the action of the first water pump 30, the condensate enters the pipe, passes through the filter 40, and flows into the water storage device 20 after filtration. In some embodiments, the drip tray 10 is also equipped with a guide pipe. When the user is not using the air conditioner 100 for humidification, the condensate can be discharged through the guide pipe, preventing the drip tray 10 from overflowing when it is full of condensate. This prevents the drip tray 10 from overflowing and causing the walls to turn black and moldy, affecting the overall aesthetics of the room, and also prevents the air conditioner 100 from malfunctioning due to overflow.

[0022] It is worth mentioning that condensate forms when the evaporator is operating. Due to the low surface temperature of the evaporator, the conditions for water vapor condensation are met, causing water vapor in the air to condense and condense. When the dewdrops grow to a certain size, they slide down into the water collection tray 10, thus forming condensate. It should be noted that because airborne impurities such as suspended dust, microorganisms, and chemicals easily adhere to the condensate, and the water collection tray 10 of the air conditioner 10 easily accumulates dust and microorganisms, the discharged condensate is not very clean. Therefore, the condensate cannot be directly used to achieve the humidification function of the air conditioner 100 and needs to be filtered through the filter 40. However, a continuous influx of condensate into the filter 40 leads to an increasing amount of particulate impurities trapped inside, affecting the filter 40's efficiency and lifespan. The air conditioner 100 of this embodiment includes a water storage device 20 and a first water level sensor 50. When the user turns on the humidification mode of the air conditioner 100, the first water pump 30 draws condensate from the water collection tray 10, and the condensate, after being filtered through the filter 40, enters the water storage device 20. After the air conditioner 100 is turned on, the first water level sensor 50 can detect whether the water in the water storage device 20 is higher than the first threshold. If the water is higher than the first threshold, the first water pump 30 is turned off. In this way, the filter 40 does not need to work continuously, which can reduce the flow rate of condensate filtered by the filter 40 and thus extend the service life of the filter 40.

[0023] The first water pump 30 includes, but is not limited to, positive displacement pumps, vane pumps, etc. The first water pump 30 may be partially installed inside the water receiving pan 10 and in contact with the bottom of the water receiving pan 10. The first water pump 30 may also be connected to the water receiving pan 10 and the water storage device 20 through a pipeline. The first water pump 30 can transport the condensate in the water receiving pan 10 so that the filtered condensate can flow into the water storage device 20.

[0024] The first water level sensor 50 can be one type of liquid level sensor. The first water level sensor 50 includes, but is not limited to, float-type liquid level sensors, float-ball type liquid level transmitters, hydrostatic liquid level sensors, ultrasonic liquid level sensors, radar liquid level sensors, etc. The first water level sensor 50 can be understood as a high water level sensor. The first water level sensor 50 can detect whether the water in the water storage device 20 is higher than a first threshold. The first threshold can be set by the air conditioner 100 before leaving the factory, and is not limited here. In some embodiments, the water in the water storage device 20 is considered to be higher than the first threshold when the water in the water storage device 20 is full, and thus the first water pump 30 can be shut off when the water in the water storage device 20 is full.

[0025] Please refer to it again. Figure 1 , Figure 2 and Figure 3 In some embodiments, the air conditioner 100 includes a second water pump 60 and a second water level sensor 70. The second water pump 60 is used to draw water from the water storage device 20 for humidification, and the second water level sensor 70 is used to detect whether the water level in the water storage device 20 is below a second threshold. The second threshold is less than a first threshold. The control method includes: Step 02: If the second water level sensor 70 detects that the water level in the water storage device 20 is lower than the second threshold, the second water pump 60 is turned off.

[0026] The control method of this application embodiment can be implemented by the air conditioner 100 of this application embodiment. Specifically, the air conditioner 100 includes a processor 80, and step 02 can be implemented by the processor 80. That is, the processor 80 is used to: shut down the second water pump 60 when the second water level sensor 70 detects that the water in the water storage device 20 is lower than the second threshold.

[0027] Specifically, the second water pump 60 includes, but is not limited to, a positive displacement pump, a vane pump, etc. The second water pump 60 may be partially installed within the water storage device 20 and in contact with the bottom of the water storage device 20. The second water pump 60 may also be connected to the water storage device 20 and the humidification component via a water pipe. The second water pump 60 can deliver filtered condensate from the water storage device 20, allowing the filtered condensate to flow to the humidification component to achieve the humidification function of the air conditioner 100.

[0028] The second water level sensor 70 can be any type of liquid level sensor. The second water level sensor 70 includes, but is not limited to, float-type liquid level sensors, float-ball type liquid level transmitters, hydrostatic liquid level sensors, ultrasonic liquid level sensors, radar liquid level sensors, etc. The second water level sensor 70 can be understood as a low water level sensor. After the air conditioner 100 is turned on, the second water level sensor 70 can detect whether the water in the water storage device 20 is below a second threshold. The second threshold is less than the first threshold. The second threshold can be set by the air conditioner 100 before leaving the factory, and is not limited here. In some embodiments, if there is still a small amount of water at the bottom of the water storage device 20, it can also be considered that the water in the water storage device 20 is below the second threshold, and the second water pump 60 can be turned off. This ensures that the second water pump 60 does not run dry, avoids the noise generated during dry running, and improves the user experience.

[0029] In one embodiment, after the air conditioner 100 is turned on, the second water level sensor 70 can first detect whether the water level in the water storage device 20 is below a second threshold. If it is not below the second threshold, the second water pump 60 can be turned on. Then, the first water level sensor 50 can be used to detect whether the water level in the water storage device 20 is above the first threshold. If it is not above the first threshold, the first water pump 30 can be turned on. After the first water pump 30 is turned on, the first water level sensor 50 is used to detect whether the water level in the water storage device 20 is above the first threshold. If the water level is above the first threshold, the first water pump 30 is turned off, while the second water pump 60 remains on.

[0030] Please see Figure 4 In some implementations, the control method includes: Step 03: When the first water level sensor 50 detects that the water in the water storage device 20 is higher than the first threshold, the second water pump 60 is started to work for a first predetermined time, and then the first water pump 30 is started.

[0031] The control method of this application embodiment can be implemented by the air conditioner 100 of this application embodiment. Specifically, the air conditioner 100 includes a processor 80, and step 03 can be implemented by the processor 80. That is, the processor 80 is used to: start the second water pump 60 after the first water level sensor 50 detects that the water in the water storage device 20 is higher than the first threshold, and then start the first water pump 30.

[0032] Specifically, when the first water level sensor 50 detects that the water level in the water storage device 20 is higher than a first threshold, the first water pump 30 is turned off, and the filter 40 no longer needs to continuously filter condensate. The second water pump 60 is then turned on, allowing it to draw water from the water storage device 20 to the humidification component. After the second water pump 60 is turned on, the water level in the water storage device 20 gradually decreases. After the second water pump 60 operates for a first predetermined period, the first water pump 30 is turned on again. This ensures that the air conditioner 100 can normally perform its humidification function, avoids the first water pump 30 continuously drawing condensate which would cause the filter 40 to filter condensate for an extended period, and also prevents the second water pump 60 from running dry.

[0033] In some implementations, the control method includes: The first predetermined duration is determined based on the flow rate of the second water pump 60, the capacity of the water storage device 20, and the humidification requirements.

[0034] The control method of this application embodiment can be implemented by the air conditioner 100 of this application embodiment. Specifically, the air conditioner 100 includes a processor 80, and the above steps can be implemented by the processor 80. That is to say, the processor 80 is used to: determine a first predetermined duration based on the flow rate of the second water pump 60, the capacity of the water storage device 20, and the humidification requirement.

[0035] Specifically, the processor 80 can obtain the flow rate and humidification requirement of the second water pump 60, which can be set by the user. For example, the user can use the remote control of the air conditioner 100 to select the current humidification requirement as 20%, 40%, 60%, 75%, 100%, etc., without limitation. Within the same time period, the flow rate of the second water pump 60 is greater when the humidification requirement is 100% than when the humidification requirement is 20%. In some embodiments, the processor 80 determines a first predetermined time period of A hours based on the flow rate of the second water pump 60, the capacity of the water storage device 20, and the humidification requirement. Thus, the first water pump 30 is turned on after the second water pump 60 has been operating for A hours.

[0036] Please continue reading. Figure 4 In some implementations, the control method includes: Step 04: When the second water level sensor 70 detects that the water in the water storage device 20 is lower than the second threshold, the first water pump 30 is started to work for a second predetermined time, and then the second water pump 60 is started.

[0037] The control method of this application embodiment can be implemented by the air conditioner 100 of this application embodiment. Specifically, the air conditioner 100 includes a processor 80, and step 04 can be implemented by the processor 80. That is, the processor 80 is used to: start the first water pump 30 to work for a second predetermined time after the second water level sensor 70 detects that the water in the water storage device 20 is lower than the second threshold, and then start the second water pump 60.

[0038] Specifically, when the second water level sensor 70 detects that the water level in the water storage device 20 is below the second threshold, the second water pump 60 is shut off to prevent it from running dry. Meanwhile, the first water pump 30 is activated, allowing it to draw condensate from the drip tray 10, filter it using the filter 40, and then deliver it to the water storage device 20. After the first water pump 30 is activated, the water level in the water storage device 20 gradually increases. After the first water pump 30 has operated for a predetermined period, the second water pump 60 is activated again. This ensures that the air conditioner 100 can perform its humidification function normally, prevents the second water pump 60 from running dry and generating noise, and improves the user experience.

[0039] In some embodiments, the second predetermined duration can be 5 minutes. That is, when the second water level sensor 70 detects that the water level in the water storage device 20 is below a second threshold, the first water pump 30 is turned on for 5 minutes before the second water pump 60 is turned on. Using 5 minutes as the second predetermined duration is experimental data obtained after multiple experiments by the R&D personnel. A second predetermined duration of 5 minutes ensures both a good user experience and allows the water capacity in the water storage device 20 to achieve the humidification function. In some embodiments, the second predetermined duration can also be 6 minutes, 8 minutes, 10 minutes, etc., and is not limited here.

[0040] Please see Figure 5 In some implementations, the control method includes: Step 05: Obtain the time difference when the air conditioner is in humidification mode 100. The time difference is the difference between the current start time and the previous start time. Step 06: If the time difference is greater than the preset time difference, activate the smart cleaning function to clean the evaporator of the air conditioner 100.

[0041] The control method of this application embodiment can be implemented by the air conditioner 100 of this application embodiment. Specifically, the air conditioner 100 includes a processor 80, and steps 05 and 06 can be implemented by the processor 80. That is, the processor 80 is used to: obtain the time difference when the humidification mode of the air conditioner 100 is turned on, the time difference being the difference between the current turn-on time and the previous turn-on time; and when the time difference is greater than a preset time difference, activate the intelligent cleaning function to clean the evaporator of the air conditioner 100.

[0042] Specifically, air conditioners that have not been used for a long time will accumulate dust. Suspended dust, microorganisms, chemicals, and other impurities in the air easily accumulate on the evaporator fins. The condensate formed by the evaporator will also become dirtier, and the recirculated condensate passing through the filter (40) is more likely to clog the filter, affecting its lifespan. Therefore, it is necessary to clean the evaporator when turning on the air conditioner again after a long period of inactivity.

[0043] When a user turns on air conditioner 100 and uses its humidification mode, processor 80 can obtain the last time air conditioner 100 was turned on. Combining this with the current time of use, a time difference is calculated. If this time difference is greater than a preset time difference, the intelligent cleaning function is activated to clean the evaporator of air conditioner 100. The intelligent cleaning function can clean the evaporator and perform high-temperature sterilization. In one embodiment, the user can turn on air conditioner 100 using a remote control and use its humidification mode. Processor 80 obtains that the last time air conditioner 100 was turned on was January 1, 2022, at 23:00, and the current time of use is January 11, 2022, at 23:00, resulting in a time difference of 240 hours. The preset time difference can be 120 hours. If this time difference is greater than the preset time difference, the intelligent cleaning function is activated to clean the evaporator of air conditioner 100.

[0044] It should be noted that the examples and specific figures mentioned above are for the purpose of illustrating the implementation of this application and should not be construed as limiting the scope of protection of this application.

[0045] Please see Figure 6 In some implementations, the control method includes: Step 07: With the air conditioner in humidification mode 100 turned on, obtain the degree of dirt and clogging of filter 40; Step 08: Clean the filter if the degree of dirt and clogging is greater than the preset degree of dirt and clogging.

[0046] The control method of this application embodiment can be implemented by the air conditioner 100 of this application embodiment. Specifically, the air conditioner 100 includes a processor 80, and steps 07 and 08 can both be implemented by the processor 80. That is to say, the processor 80 is used to: obtain the time difference when the humidification mode of the air conditioner 100 is turned on, the time difference being the difference between the current turn-on time and the previous turn-on time; and when the time difference is greater than a preset time difference, activate the intelligent cleaning function to clean the evaporator of the air conditioner 100.

[0047] Specifically, when filter 40 filters condensate, condensate flows in through the inlet of filter 40 and flows out through the outlet after filtration. However, as the condensate passes through the filter screen of filter 40, particulate impurities in the condensate are trapped inside the screen. Over time, as filter 40 filters condensate, the trapped particulate impurities accumulate, slowing down the filtration process. Meanwhile, condensate continues to flow into the inlet, causing the filter screen pores to become smaller, further affecting the filtration speed. Therefore, it is necessary to clean the filter screen.

[0048] When the user turns on the air conditioner 100 and uses its humidification mode, the degree of filter clogging can be detected by a sensor. If the detected degree of clogging is greater than a preset level, the filter is cleaned, thus extending the lifespan of the filter 40 and ensuring its working efficiency. If the detected degree of clogging is less than the preset level, the second water level sensor 70 detects whether the water level in the water storage device 20 is below a second threshold. If the second water level sensor 70 detects that the water level in the water storage device 20 is not below the second threshold, the second water pump 60 is activated, allowing the air conditioner 100 to humidify the environment normally.

[0049] It is worth mentioning that, in some implementations, if the degree of dirt clogging of the filter is found to be greater than the preset degree of dirt clogging, the filter can be cleaned by activating the intelligent cleaning function, which will rinse and sterilize the filter at high temperature; a reminder message can also be issued to remind the user to clean the filter, which is not limited here.

[0050] Please see Figure 7 In some embodiments, the air conditioner 100 includes a second water level sensor 70, which is used to detect whether the water level in the water storage device 20 is below a second threshold. The control method includes: Step 09: When the humidification mode of the air conditioner 100 is turned on, determine whether the air conditioner 100 is also in the cooling mode. If the air conditioner 100 is in the cooling mode and the second water level sensor 70 detects that the water in the water storage device 20 is lower than the second threshold, turn on the first water pump 30.

[0051] The control method of this application embodiment can be implemented by the air conditioner 100 of this application embodiment. Specifically, the air conditioner 100 includes a processor 80, and step 09 can be implemented by the processor 80. That is, the processor 80 is used to: determine whether the air conditioner 100 is simultaneously in cooling mode when the humidification mode of the air conditioner 100 is turned on; and turn on the first water pump 30 when the air conditioner 100 is in cooling mode and the second water level sensor 70 detects that the water in the water storage device 20 is lower than the second threshold.

[0052] Specifically, the air conditioner 100 includes multiple operating modes, including but not limited to cooling mode, humidification mode, dehumidification mode, heating mode, and fan mode. In some embodiments, the humidification mode can be activated simultaneously with the cooling mode; the humidification mode can be activated simultaneously with the fan mode; and the dehumidification mode can be activated simultaneously with the heating mode.

[0053] When the user turns on the humidification mode of air conditioner 100, it is determined whether air conditioner 100 is also in cooling mode. When air conditioner 100 is in cooling mode, the evaporator of air conditioner 100 is working. The compressor of air conditioner 100 compresses the refrigerant into a liquid state, which flows through the evaporator. The evaporator absorbs heat through evaporation. At this time, the surface temperature of the evaporator is low, meeting the conditions for water vapor condensation. The water vapor condenses and condenses. When the dewdrops grow to a certain size, they will slide down into the drip tray 10, thus forming condensate. Therefore, air conditioner 100 can produce condensate when in cooling mode. The condensate can drip onto the drip tray 10, and the condensate in the drip tray 10 can be used to humidify the room.

[0054] When the air conditioner 100 is in cooling mode and the second water level sensor 70 detects that the water level in the water storage device 20 is below the second threshold, the first water pump 30 is activated to draw condensate filtered by the filter 40 into the water storage device 20. After the first water pump 30 has been operating for a period of time, when the first water level sensor 50 detects that the water level in the water storage device 20 is above the first threshold, the first water pump 30 is turned off. In this way, when the air conditioner 100 is in cooling mode, condensate can be continuously collected in the drip tray, achieving condensate recycling. At the same time, the first water level sensor 50 can also prevent the first water pump 30 from continuously drawing condensate, thus avoiding prolonged condensate filtration by the filter 40, extending the filter 40's lifespan, and saving energy.

[0055] In some implementations, when a user turns on the humidification mode of the air conditioner 100, if it is determined that the air conditioner 100 is not simultaneously in cooling mode, the fresh air logic humidity control function of the air conditioner 100 can be activated to achieve the humidification function of the air conditioner 100.

[0056] Please see Figure 8 In some implementations, after the user turns on the air conditioner 100, they can use the remote control to select the humidification mode. The processor 80 can obtain the time difference to determine whether the air conditioner 100 has not been used for a long time. If it is determined that the air conditioner 100 has not been used for a long time, the intelligent cleaning function is activated to clean the air conditioner 100. After cleaning is completed, it is determined whether the air conditioner 100 is simultaneously in cooling mode. If it is determined that the air conditioner 100 has not been used for a long time, it directly determines whether the air conditioner 100 is simultaneously in cooling mode.

[0057] If it is determined that the air conditioner 100 is not simultaneously in cooling mode, then the humidification function of the air conditioner 100 is activated by using the fresh air logic humidity control function. If it is determined that the air conditioner 100 is simultaneously in cooling mode, then the second water level sensor 70 is used to detect whether the water in the water storage device 20 is lower than the second threshold.

[0058] If the water level is below the second threshold, the first water pump 30 is activated and operates for a second predetermined time. During this time, the second water pump 60 is deactivated. After the first water pump 30 has operated for the second predetermined time, the second water pump 60 is activated. The first water level sensor 50 then detects whether the water level in the water storage device 20 is above the first threshold. If it is above the first threshold, the first water pump 30 is deactivated, and the second water pump 60 is activated and operates for the first predetermined time. After the second water pump 60 has operated for the first predetermined time, the second water level sensor 70 detects whether the water level in the water storage device 20 is below the second threshold. If it is below the second threshold, the first water pump 30 is activated again. This cycle repeats to achieve the humidification function of the air conditioner 100.

[0059] This application also provides a computer-readable storage medium storing a computer program that, when executed by a processor, causes the processor to perform the steps of the control method described in any of the above embodiments.

[0060] In one embodiment, when the program is executed by a processor, the following steps of the control method are implemented: Step 01: When the first water level sensor 50 detects that the water in the water storage device 20 is higher than the first threshold, the first water pump 30 is turned off.

[0061] The computer-readable storage medium of this application embodiment can shut down the first water pump 30 when the water level in the water storage device 20 is higher than a first threshold. This avoids the first water pump 30 continuously drawing condensate, which would cause the filter 40 to filter condensate for an extended period of time, thus extending the service life of the filter 40.
