[0053] First, those skilled in the art should understand that these embodiments are only used to explain the technical principles of the embodiments of the present application, and are not intended to limit the protection scope of the embodiments of the present application. Those skilled in the art can adjust them as needed in order to adapt to specific application occasions.

[0055] In addition, it needs to be explained that, in the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication inside two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0056] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0057] The air conditioner in the related art, when starting the refrigeration mode, the low-temperature and low-pressure liquid refrigerant flows through the evaporator and exchanges heat with the air, and after absorbing the heat in the air, it is gasified into low-temperature and low-pressure gaseous refrigerant, so as to reduce the temperature of the air, so as to achieve the effect of refrigeration.

[0058] In summer, the temperature of the air is relatively high and the humidity is relatively large. When the air conditioner starts the refrigeration mode, the water vapor in the indoor air condenses on the surface of the evaporator, producing a large amount of condensed water, part of which adheres to the surface of the evaporator, reducing the heat exchange effect of the evaporator.

[0059] The embodiments provide a control method and device of an air conditioner and the air conditioner. When the air conditioner is in a refrigeration mode and the humidity of indoor air is greater than a preset humidity, the filter screen is controlled to relax, so as to improve the water vapor collecting capacity of the filter screen, so that part of the water vapor in the air is collected by the filter screen when the indoor air enters the shell from the air inlet, thereby reducing the amount of water vapor in the air reaching the indoor heat exchanger, and reducing the water adhering to the surface of the indoor heat exchanger, so that the heat exchange efficiency of the indoor heat exchanger is increased.

[0060] The principles and characteristics of the embodiments of the present application will be described below in combination with the drawings. The examples are only used to explain the embodiments of the present application, and are not used to limit the scope of the embodiments of the present application.

[0061] As shown in Figure 1 The embodiments of the present application provide a control method of an air conditioner. The air conditioner comprises an air conditioner indoor unit and an air conditioner outdoor unit. The air conditioner outdoor unit comprises a shell, a compressor, an outdoor heat exchanger and a throttling element. The shell is used to be placed outdoors. The compressor, the outdoor heat exchanger and the throttling element are arranged in the shell.

[0062] The air conditioner indoor unit comprises a shell, a filter screen, an indoor heat exchanger and an indoor fan. The filter screen, the indoor heat exchanger and the indoor fan are arranged in the shell. The shell is provided with an air inlet and an air outlet. The indoor heat exchanger is arranged between the air inlet and the air outlet. The filter screen is arranged between the air inlet and the indoor heat exchanger. The indoor fan is arranged between the indoor heat exchanger and the air outlet. The filter screen filters the air entering the shell to avoid impurities in the air from adhering to the indoor heat exchanger and affecting the heat exchange efficiency of the indoor heat exchanger and the air. The compressor, the outdoor heat exchanger, the throttling element and the indoor heat exchanger are connected in series through a pipeline. The pipeline circulates refrigerant.

[0063] When the air conditioner is started in the cooling mode, the compressor compresses the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant is delivered to the outdoor heat exchanger and becomes liquid refrigerant at normal temperature and high pressure after heat dissipation. The liquid refrigerant at normal temperature and high pressure enters the indoor heat exchanger through the throttling element. The liquid refrigerant at normal temperature and high pressure is cooled and decompressed into low-temperature and low-pressure liquid refrigerant when flowing through the throttling element. The low-temperature and low-pressure liquid refrigerant exchanges heat with the air when flowing through the indoor heat exchanger, and is gasified into low-temperature and low-pressure gaseous refrigerant after absorbing heat in the air. The temperature of the air and the indoor heat exchanger is reduced. The indoor fan blows out the low-temperature gas to reduce the temperature of the indoor air, thereby realizing the cooling of the air conditioner.

[0064] When the air conditioner is started in the heating mode, the flow direction of the refrigerant in the outdoor heat exchanger and the indoor heat exchanger is opposite to that when the air conditioner is started in the cooling mode. The compressor compresses the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gaseous refrigerant. The high-temperature and high-pressure gaseous refrigerant exchanges heat with the air when delivered to the indoor heat exchanger, so that the gaseous refrigerant is cooled and condensed into liquid refrigerant at normal temperature and high pressure. The temperature of the air is increased. The indoor fan blows out the high-temperature gas to increase the temperature of the indoor air, thereby realizing the heating of the air conditioner. The liquid refrigerant enters the outdoor heat exchanger through the throttling element. The liquid refrigerant at normal temperature and high pressure is cooled and decompressed into low-temperature and low-pressure liquid refrigerant when flowing through the throttling element. The low-temperature and low-pressure liquid refrigerant exchanges heat with the air when flowing through the outdoor heat exchanger, and is gasified into low-temperature and low-pressure gaseous refrigerant after absorbing heat in the air, thereby reducing the temperature of the air and the outdoor heat exchanger.

[0065] Reference Figure 1 The control method of the air conditioner comprises:

[0066] S101, when the working mode of the air conditioner is the cooling mode, the indoor air humidity and the preset humidity are determined.

[0067] The preset humidity can be 50%-80%. The preset humidity is the humidity that makes the user feel comfortable. If the indoor air humidity is less than the preset humidity, it means that the indoor air humidity is relatively dry. When the air conditioner is started in the cooling mode, it is not easy to form condensate water on the surface of the indoor heat exchanger.

[0068] If the indoor air humidity is equal to the preset humidity, it indicates that the indoor air humidity is appropriate, and when the air conditioner is started in the cooling mode, a small amount of condensate water is formed on the surface of the indoor heat exchanger.

[0069] If the indoor air humidity is greater than the preset humidity, it indicates that the indoor air humidity is large, and when the air conditioner is started in the cooling mode, a large amount of condensate water is easily formed on the surface of the indoor heat exchanger.

[0070] S102, if the indoor air humidity is greater than the preset humidity, the filter screen of the air conditioner is controlled to be relaxed to improve the water vapor collection capacity of the filter screen, wherein the filter screen has a water collecting structure in the relaxed state.

[0071] When the indoor air humidity is greater than the preset humidity, a large amount of condensate water is easily formed on the surface of the indoor heat exchanger, at this time, the filter screen 100 of the air conditioner is controlled to be relaxed, so that the filter screen 100 has a water collecting structure 10, and the water collecting structure 10 can collect the water in the air flowing through the filter screen 100, so as to improve the water vapor collection capacity of the filter screen 100. After the indoor air enters the shell from the air inlet, part of the water vapor in the air is collected by the filter screen 100, so that the amount of water vapor in the air reaching the indoor heat exchanger is reduced, thereby reducing the water on the surface of the indoor heat exchanger, and increasing the heat exchange efficiency of the indoor heat exchanger.

[0072] The filter screen 100 with the water collecting structure 10 not only has the water vapor collection capacity, but also has the effect of filtering solid impurities in the air.

[0073] In some embodiments, the control of the filter screen 100 of the air conditioner to be relaxed in S102 to improve the water vapor collection capacity of the filter screen 100 specifically includes:

[0074] The filter screen 100 is relaxed so that the wire 20 of the filter screen 100 has a bifurcated segment, the bifurcated segment surrounds a hollow space in the shape of a spindle, and the hollow space forms the water collecting structure 10.

[0075] Reference Figure 2 The filter screen 100 has the water collecting structure 10 in the relaxed state, which can be in the shape of a hollow spindle. The water collecting structure 10 in the shape of a hollow spindle has excellent water collecting efficiency. The water in the air flowing through the filter screen 100 is continuously gathered and condensed into water droplets at the water collecting structure 10, and the water droplets flow downward to the water pan and can be discharged from the condensate water drain pipe, thereby reducing the water in the air.

[0076] Reference Figure 3 In some embodiments, the control method of the air conditioner further includes:

[0077] S103, if the indoor air humidity is less than or equal to the preset humidity, the filter screen is controlled to be stretched to reduce the water vapor collection capacity of the filter screen.

[0078] When the indoor air humidity is less than or equal to the preset humidity, the surface of the indoor heat exchanger is not easy to form condensate water or forms less condensate water, and the small amount of condensate water has less influence on the heat exchange efficiency of the indoor heat exchanger. At this time, the filter screen 100 does not need to collect the water in the air, and therefore, the filter screen 100 is controlled to be stretched to weaken the water collection ability of the water collection structure 10, thereby reducing the water vapor collection ability of the filter screen 100.

[0079] With reference to Figure 4 The above control of the stretching of the filter screen 100 to reduce the water vapor collection ability of the filter screen 100 specifically includes: the filter screen 100 is tightened to make the screen wire 20 of the filter screen 100 in a compact linear shape. At this time, the filter screen 100 does not have the water collection structure 10 and does not have the water vapor collection ability, but only has the function of filtering solid impurities.

[0080] With reference to Figure 5 In some embodiments, after S102, the method further includes:

[0081] S104, detecting the turbidity of the water dripping from the filter screen.

[0082] In some implementations, the turbidity of the water dripping from the filter screen 100 can be determined according to the conductivity of the water dripping from the filter screen 100. The higher the conductivity of the water, the more impurities in the water, and the greater the turbidity of the water.

[0083] In other implementations, the turbidity of the water dripping from the filter screen 100 can be detected by a turbidity meter.

[0084] S105, when the turbidity of the water dripping from the filter screen is less than or equal to a preset turbidity, the water dripping from the filter screen is introduced into a water box of a water-using device of the air conditioner, and the water-using device includes at least one of a humidifying device and a heat exchange fin cleaning device.

[0085] When the turbidity of the water dripping from the filter screen 100 is less than or equal to the preset turbidity, the water is relatively clear and can be reused. At this time, the water dripping from the filter screen 100 can be introduced into the water box of the water-using device of the air conditioner, and the water-using device can include at least one of the humidifying device and the heat exchange fin cleaning device.

[0086] When the water dripping from the filter screen 100 is introduced into the water box of the humidifying device, the water dripping from the filter screen 100 can be used to humidify the indoor space; when the water dripping from the filter screen 100 is introduced into the water box of the heat exchange fin cleaning device, the water dripping from the filter screen 100 can be used to clean the heat exchange fin, thereby improving the utilization efficiency of the water and saving water resources.

[0087] With reference to Figure 6 In some embodiments, the control method of the air conditioner further includes:

[0088] S106、In the case that the indoor air humidity is greater than the preset humidity, the swing blade of the air conditioner is controlled to move so as to make the air outlet direction of the air conditioner tilt upward.

[0089] In the case that the indoor air humidity is greater than the preset humidity, it indicates that the indoor air humidity is relatively large, at this time, the swing blade of the air conditioner is controlled to move so as to make the air outlet direction of the air conditioner tilt upward, avoiding the humid air directly blowing to the user, and improving the comfort of the user.

[0090] The device for implementing the above method is described below.

[0091] Reference Figure 7 The embodiment provides a control device 200 of an air conditioner, which comprises a determination module 21 and a control module 22.

[0092] The determination module 21 is used for determining the indoor air humidity and the preset humidity when the working mode of the air conditioner is the cooling mode.

[0093] The preset humidity can be 50%-80%, and the preset humidity is the humidity that makes the user feel comfortable. If the indoor air humidity is less than the preset humidity, it indicates that the indoor air humidity is relatively dry, and the surface of the indoor heat exchanger is not easy to form condensate water when the air conditioner is started in the cooling mode.

[0094] If the indoor air humidity is equal to the preset humidity, it indicates that the indoor air humidity is appropriate, and a small amount of condensate water will be formed on the surface of the indoor heat exchanger when the air conditioner is started in the cooling mode.

[0095] If the indoor air humidity is greater than the preset humidity, it indicates that the indoor air humidity is relatively large, and a large amount of condensate water is easy to be formed on the surface of the indoor heat exchanger when the air conditioner is started in the cooling mode.

[0096] The control module 22 is used for controlling the filter screen 100 of the air conditioner to relax if the indoor air humidity is greater than the preset humidity, so as to improve the water vapor collection capacity of the filter screen 100, wherein the filter screen 100 has a water collecting structure 10 in the relaxed state.

[0097] When the indoor air humidity is greater than the preset humidity, a large amount of condensate water is easy to be formed on the surface of the indoor heat exchanger, at this time, the filter screen 100 of the air conditioner is controlled to relax, so that the filter screen 100 has the water collecting structure 10, the water collecting structure 10 can collect the water in the air flowing through the filter screen 100, so as to improve the water vapor collection capacity of the filter screen 100. After the indoor air enters the shell from the air inlet, part of the water vapor in the air is collected by the filter screen 100, so that the amount of water vapor in the air reaching the indoor heat exchanger is reduced, thereby reducing the water on the surface of the indoor heat exchanger, and increasing the heat exchange efficiency of the indoor heat exchanger.

[0098] The filter screen 100 with the water collecting structure 10 not only has the water vapor collection capacity, but also has the effect of filtering the solid impurities in the air.

[0099] In some embodiments, the control module 22 is specifically configured to control the filter screen 100 to relax, so that the filaments 20 of the filter screen 100 have bifurcated segments, and the bifurcated segments enclose a hollow space in the shape of a spindle, and the hollow space forms the water collecting structure 10, if the indoor air humidity is greater than the preset humidity.

[0100] With reference to Figure 2 , the filter screen 100 has the water collecting structure 10 in the relaxed state, which can be in the shape of a hollow spindle. The water collecting structure 10 in the shape of a hollow spindle has excellent water collecting efficiency. The moisture in the air flowing through the filter screen 100 continuously gathers and condenses into water droplets at the water collecting structure 10, and the water droplets flow downward to the water pan and can be discharged from the condensate drain pipe, so as to reduce the moisture in the air.

[0101] With reference to Figure 8 In some embodiments, the control device 200 further comprises:

[0102] The control module 23 is configured to control the filter screen 100 to stretch, so as to reduce the water vapor collecting capacity of the filter screen 100, if the indoor air humidity is less than or equal to the preset humidity.

[0103] When the indoor air humidity is less than or equal to the preset humidity, the surface of the indoor heat exchanger is not easy to form condensate water or forms less condensate water, and the small amount of condensate water has little effect on the heat exchange efficiency of the indoor heat exchanger. At this time, it is not necessary to collect the moisture in the air through the filter screen 100, and therefore, the filter screen 100 is controlled to stretch at this time, so as to weaken the water vapor collecting capacity of the water collecting structure 10, thereby reducing the water vapor collecting capacity of the filter screen 100.

[0104] With reference to Figure 4 The above control module 23 is specifically configured to stretch the filter screen 100, so that the filaments 20 of the filter screen 100 are in the shape of a compact line. At this time, the filter screen 100 does not have the water collecting structure 10 and does not have the water vapor collecting capacity, but only has the function of filtering solid impurities.

[0105] The above control module 22 and the control module 23 can be the same control module, which can control the filter screen 100 of the air conditioner to relax and can also control the filter screen 100 of the air conditioner to stretch. The control module 22 and the control module 23 can also be two control modules, which are respectively used to control the filter screen 100 of the air conditioner to relax and to stretch.

[0106] With reference to Figure 8 In some embodiments, the control device 200 further comprises a detection module 24 and an import module 25.

[0107] The detection module 24 is configured to detect the turbidity of the water dripping from the filter screen 100.

[0108] In some implementations, the detection module 24 can be specifically configured to determine the turbidity of the water dripping from the filter screen 100 according to the conductivity of the water dripping from the filter screen 100. The higher the conductivity of the water, the more impurities in the water, and the greater the turbidity of the water.

[0109] In other implementations, the detection module 24 can be specifically configured to detect the turbidity of the water dripping from the filter screen 100 by a turbidimeter.

[0110] The introduction module 25 is configured to introduce the water dripping from the filter screen 100 into a water box of a water-using device of the air conditioner when the turbidity of the water dripping from the filter screen 100 is less than or equal to a preset turbidity, the water-using device including at least one of a humidifying device and a heat exchange fin cleaning device.

[0111] When the turbidity of the water dripping from the filter screen 100 is less than or equal to the preset turbidity, the water is relatively clean and can be reused, and thus the water dripping from the filter screen 100 can be introduced into the water box of the water-using device of the air conditioner, which can include at least one of the humidifying device and the heat exchange fin cleaning device.

[0112] When the water dripping from the filter screen 100 is introduced into the water box of the humidifying device, the water dripping from the filter screen 100 can be used to humidify the indoor space, and when the water dripping from the filter screen 100 is introduced into the water box of the heat exchange fin cleaning device, the water dripping from the filter screen 100 can be used to clean the heat exchange fins, thereby improving the utilization efficiency of the water and saving water resources.

[0113] Reference Figure 8 In some embodiments, the control device 200 further includes:

[0114] The control module 26 is configured to control the swing blade of the air conditioner to move so as to tilt the air outlet direction of the air conditioner upward when the indoor air humidity is greater than a preset humidity.

[0115] When the indoor air humidity is greater than the preset humidity, it indicates that the indoor air humidity is relatively large, and thus the swing blade of the air conditioner is controlled to rotate so as to tilt the air outlet direction of the air conditioner upward, thereby avoiding the humid air from directly blowing on the user and improving the comfort of the user.

[0116] The control device 200 of the air conditioner according to the embodiments of the present application comprises a determining module 21 and a control module 22. The determining module 21 is configured to determine the indoor air humidity and a preset humidity when the working mode of the air conditioner is the cooling mode. The control module 22 is configured to control the filter screen 100 of the air conditioner to relax if the indoor air humidity is greater than the preset humidity, so as to improve the water vapor collection capacity of the filter screen 100. The filter screen 100 has the water collecting structure 10 in the relaxed state. When the indoor air humidity is greater than the preset humidity, a large amount of condensate water is likely to form on the surface of the indoor heat exchanger. At this time, the filter screen 100 of the air conditioner is controlled to relax, so that the filter screen 100 has the water collecting structure 10, and the water collecting structure 10 can collect the water vapor in the air flowing through the filter screen 100, so as to improve the water vapor collection capacity of the filter screen 100. After the indoor air enters the shell from the air inlet, part of the water vapor in the air is collected by the filter screen 100, so that the amount of water vapor in the air reaching the indoor heat exchanger is reduced, thereby reducing the water vapor attached to the surface of the indoor heat exchanger, and the heat exchange efficiency of the indoor heat exchanger is increased.

[0117] Reference Figure 9 The embodiments of the present application also provide an air conditioner 300, which comprises an air conditioner indoor unit and an air conditioner outdoor unit. The air conditioner outdoor unit comprises a shell, a compressor, an outdoor heat exchanger, a throttling element, a computer board, at least one memory 31 and at least one processor 32. The shell is used to be placed outdoors. The compressor, the outdoor heat exchanger and the throttling element are arranged in the shell. The air conditioner indoor unit comprises a shell, a filter screen 100, an indoor heat exchanger and an indoor fan.
