Furthermore, the specific features, structures, materials or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0062] like Figure 4-10As shown, an embodiment of the present invention provides an air conditioner self-cleaning control system, including a water tank 2, a three-way valve assembly 3, a drain pipe 6, a cleaning unit and a control switch assembly 7.

When the air conditioner is running in the cooling and dehumidification mode, the water outlet 1 of the water receiving pan of the air conditioner is prone to generate condensed water. Therefore, the three-way valve assembly 3 is used to switch the connection between the water tank 2 and the drain pipe 6, thereby realizing the collection and discharge of condensed water. The structure is simple and is conducive to the rapid collection of condensed water. When performing the cleaning action, a clean water source is provided, and no external water source is required, so cleaning is convenient. The system can automatically detect whether the water tank is full of water before performing the cleaning action. It is intelligent and does not require disassembly of parts during the cleaning process, thereby improving cleaning efficiency.

[0063] Preferably, if Fig.10 As shown, the control switch assembly 7 includes a housing 73 extending from the top of the water tank 2 in a direction away from the water tank 2, and a floating valve 71 and a control switch 72 respectively connected to the housing 73. The first end of the floating valve 71 close to the control switch 72 is arranged inside the housing 73, and the second end of the floating valve 71 away from the control switch 72 is arranged inside the water tank 2. The floating valve 71 is suitable for moving along the height direction of the water level in the water tank 2 to close or disconnect the static and dynamic contacts in the control switch 72. Thus, the specific structure of the control switch assembly 7 is defined, and the control is convenient and the sensitivity is high. It should be noted that in this embodiment, the height direction of the water level is the direction of Y in the figure.

[0064] In some specific embodiments, after the water level rises to contact the floating valve 71, the floating valve 71 rises under the action of buoyancy, pushing the static and dynamic contacts in the control switch 72 to contact, indicating that the water tank 2 is full of water; the static and dynamic contacts in the control switch 72 separate, indicating that the water tank 2 is not full of water. At this time, the control switch sends a warning signal to the main control to remind the user to add water manually. The control is convenient, the sensitivity is high, and the detection is accurate.

[0065] Preferably, the shell 73 is a rectangular structure with a simple structure. The floating valve 71 is an "I"-shaped structure, including a first end, a second end and a third end, and the third end is connected between the first end and the second end. The first end and the second end of the floating valve 71 are the top and bottom ends of the floating valve 71, respectively. A through hole suitable for the third end to pass through is set at the bottom of the shell 73, and the inner diameter of the through hole is smaller than the length of the first end and the second end. This structural setting is suitable for the floating valve to move along the height direction of the water level in the water tank 2, and the structure is simple.

[0066] Preferably, the three-way valve assembly 3 includes a valve 31 and a motion structure drivingly connected to the valve 31, and the motion structure is suitable for driving the valve 31 to move, thereby switching the connection between the water tank 2 and the drain pipe 6, with a simple structure and convenient switching.

[0067] Preferably, the motion structure includes a motor 32, a gear 35 and a rack 36, the motor 32 is drivingly connected to the gear 35, the gear 35 is meshed with the rack 36, the rack 36 is connected to the valve 31, and the rack 36 can drive the valve 31 to move with the rotation of the gear 35. Thus, the specific structural composition of the motion structure is defined, the structure is simple, and the control is accurate.

[0068] In some specific embodiments, the valve 31 is a flat plate structure, and when the rack 36 drives the valve 31 to move as the gear 35 rotates, the plate surface of the valve 31 is suitable for covering the connection between the water outlet 1 and the water tank 2 or the connection between the water outlet 1 and the drain pipe 6. The structure is simple.

[0069] like Figure 4 As shown, preferably, the motion structure also includes a motor frame 33 and a connecting plate 34, the motor 32 is fixed on the motor frame 33, and one end of the connecting plate 34 is fixedly connected to the motor frame 33, and the other end of the connecting plate 34 is fixedly connected to the three-way valve assembly 3, so that the installation structure of the motor 32 is simple and firmly installed.

[0070] In this embodiment, there is no restriction on the connection method between the motor 32 and the motor frame 33 and the connection method between the connecting plate 34 and the motor frame 33. In some preferred embodiments, in order to facilitate installation and disassembly, the motor 32 is connected to the motor frame 33 with screws, and the connecting plate 34 is connected to the motor frame 33 with screws, and the connection is convenient and firm.

[0071] In this embodiment, there is no limitation on the connection method between the connecting plate 34 and the three-way valve assembly 3. In some preferred embodiments, the connecting plate 34 is integrally connected to the outer tube wall of the three-way valve assembly 3 and the connection is firm.

[0072] like Figure 7 and Figure 8As shown, in this embodiment, the three-way valve assembly 3 includes a body 30 and a first connection end 37, a second connection end 38 and a third connection end 39 respectively connected to the body 30, the first connection end 37 is also connected to the water outlet 1 of the water receiving tray of the air conditioner, the second connection end 38 is also connected to the drain pipe 6, and the third connection end 39 is also connected to the water tank 2, and the first connection end 37 and the water outlet 1 of the water receiving tray of the air conditioner are kept in a normally connected state, and the second connection end 38 and the third connection end 39 can be switched and connected through the valve 31. In some specific embodiments, when the second connection end 38 is opened, the third connection end 39 is closed, and when the second connection end 38 is closed, the third connection end is opened, that is, only one of the second connection end 38 and the third connection end 39 can be opened, and the structure is simple and the switching is convenient. It should be noted that the upper and lower parts of the body 30 in this embodiment refer to the upper and lower parts in the Y direction in the figure.

[0073] In some specific embodiments, the first connection end 37 is arranged at the upper part of the body 30, and the second connection end 38 and the third connection end 39 are arranged at the lower part of the body 30, that is, the first connection end 37 is higher than the second connection end 38 and the third connection end 39, thereby making it easier for the condensed water flowing out of the water outlet to be discharged from the drain pipe or stored in the water tank. It should be noted that in this embodiment, the first connection end 37 is higher than the second connection end 38 and the third connection end 39, which means that the maximum distance from the first connection end 37 to the horizontal plane is greater than the maximum distance from the second connection end 38 and the third connection end 39 to the horizontal plane, where the horizontal plane is the plane where the upper surface of the water tank 2 in the figure is located.

[0074] Preferably, the cleaning unit includes a water pump 4 connected to the water tank 2, a connecting water pipe 5 connected to the water pump 4, and a water spray assembly connected to the connecting water pipe 5, and the water spray assembly is arranged close to the air outlet assembly of the air conditioner. In some specific embodiments, the water spray assembly is a nozzle, and the nozzle is provided with uniform small holes, and condensed water is sprayed from the small holes and sprayed on the air outlet assembly, and the water is evenly discharged and cleaned.

[0075] In this embodiment, there is no restriction on the number of nozzles or connecting water pipes 5, which can be one or more and can be set according to actual conditions, but each nozzle is connected to at least one connecting water pipe 5. In some specific embodiments, there is one connecting water pipe 5 and one nozzle, which saves space, and by controlling the water pump 4 to start, the water in the water tank 2 is sprayed to the air outlet component for cleaning, which is convenient to clean, saves time and effort.

[0076] Compared with the prior art, the air conditioner self-cleaning control system of the present invention utilizes the principle of condensation generated by the air conditioner. After the air conditioner performs automatic cleaning, it automatically collects and stores condensed water, and provides a clean water source when performing the cleaning action. It does not require an external water source, and cleaning is convenient. There is no need to disassemble parts during the cleaning process, thereby improving the cleaning efficiency.

[0077] like Figure 1 As shown, the embodiment of the present invention also provides an air conditioner self-cleaning control method, comprising:

[0078] When receiving the self-cleaning command, the water tank 2 is detected to be full of water.

[0079] When it is detected that the water tank 2 is full of water, a self-cleaning command is executed, including:

[0080] Step S1, controlling the three-way valve assembly 3 to connect the drain pipe 6 and the water outlet 1 of the air conditioner water receiving pan, the air conditioner enters the self-cleaning mode, so as to use the air conditioner condensed water for self-cleaning, and discharge the cleaned sewage from the drain pipe 6;

[0081] Step S2, when the execution of the self-cleaning command reaches the first predetermined time, the three-way valve assembly 3 is controlled to connect the water tank 2 and the water outlet 1, and the air conditioner enters the water storage mode to store condensed water;

[0082] Step S3, when the condensed water is stored for a second predetermined time, the three-way valve assembly 3 is controlled to connect the drain pipe 6 and the water outlet 1 again to continue to discharge the condensed water;

[0083] When it is detected that the water tank 2 is not full, a warning signal is issued to remind the user to manually add water until the water tank 2 is full and the self-cleaning command is executed.

[0084] In this embodiment, the air conditioner can start the self-cleaning mode through the remote control button or the function key of the air conditioner itself, which is convenient to start. And by using the principle of condensation of air conditioner, after the air conditioner performs automatic cleaning, it automatically collects and stores condensed water, and provides a clean water source when performing the cleaning action, without the need for an external water source, and is convenient for cleaning. It can also automatically detect the fullness of the water tank before performing the cleaning action, which is intelligent, and there is no need to disassemble parts during the cleaning process, thereby improving the cleaning efficiency.

[0085] like Figure 2 As shown, preferably, using air conditioning condensate for self-cleaning includes using air conditioning condensate for self-cleaning of the air outlet component, and the self-cleaning of the air outlet component includes one or more of air duct self-cleaning, fan blade self-cleaning, or filter self-cleaning. In this embodiment, there is no restriction on the self-cleaning method of the air outlet component, and air conditioning condensate can be used to simultaneously perform self-cleaning of the air duct, fan blade self-cleaning, and filter self-cleaning, or any one of the self-cleaning of the air duct, fan blade self-cleaning, or filter self-cleaning, or any two of them can be performed simultaneously, so that cleaning is convenient and thorough.

[0086] like Figure 3As shown, preferably, when a self-cleaning command is received, the air conditioner enters a self-cleaning mode, which also includes any one or more of evaporator self-cleaning, waterway self-cleaning or appearance self-cleaning. Thus, multiple components can be cleaned at the same time, or one component can be cleaned separately, which has strong versatility.

[0087] Preferably, when a self-cleaning command is received, when the air conditioner enters the self-cleaning mode, after performing self-cleaning of the evaporator and / or self-cleaning of the air outlet component and / or self-cleaning of the appearance, it is also necessary to perform self-cleaning of the water channel. In some specific embodiments, after the air conditioner performs one or more of the self-cleaning of the evaporator, the self-cleaning of the air outlet component and the self-cleaning of the appearance, it is necessary to perform self-cleaning of the water channel, that is, after the self-cleaning mode, a self-cleaning of the water channel must be performed to clean the dirt remaining in the water channel after the self-cleaning of the evaporator and / or the self-cleaning of the air outlet component and / or the self-cleaning of the appearance, so as to prevent the self-cleaning of the water channel before other plot modes, resulting in the water channel being contaminated again by the discharged sewage in other modes after cleaning, so as to ensure thorough cleaning.

[0088] In this embodiment, there is no specific restriction on the range of the first predetermined time, and it can be adjusted according to the specific operations performed in the self-cleaning mode. For example, when evaporator self-cleaning, water channel self-cleaning or appearance self-cleaning are performed separately or simultaneously, water channel self-cleaning is also required. Therefore, the first predetermined time is longer, and when water channel self-cleaning is performed separately, the time is shorter, generally 3-5 minutes, It can be completed.

[0089] In this embodiment, there is no specific limitation on the range of the second preset time. When the humidity is high and the refrigeration setting temperature is low, condensation water is more likely to form, and the time can be shortened accordingly. In some preferred embodiments, the second preset time is 50-70 minutes. In some specific embodiments, the second preset time is 60 minutes. After this period of time, the water volume can meet the water volume required for self-cleaning of the air outlet component.

[0090] Preferably, the air conditioner enters the self-cleaning mode, and the air outlet assembly is self-cleaned using the air conditioner condensed water, including controlling the water pump 4 to start, and controlling the water pump 4 to spray the water in the water tank 2 to the air outlet assembly for cleaning. By controlling the water pump 4 to start, the condensed water stored in the water tank 2 is sprayed to the air outlet assembly for cleaning, which is convenient for cleaning, saves time and effort, and saves resources, avoiding excessive waste of resources.

[0091] Preferably, the air conditioner self-cleaning control method further includes:

[0092] After receiving the start-up command, the water in the water tank 2 is detected to be full.

[0093] When it is detected that the water tank 2 is full of water, a self-cleaning command is executed, including: controlling the three-way valve assembly 3 to connect the water tank 2 and the water outlet 1 to store condensed water, until the condensed water is stored for a third predetermined time, and controlling the three-way valve assembly 3 to connect the drain pipe 6 and the water outlet 1 again to continue to discharge the condensed water;

[0094] When it is detected that the water tank 2 is not full, a warning signal is issued to remind the user to manually add water until the water tank 2 is full and the self-cleaning command is executed.

[0095] Therefore, when the air conditioner is started, condensed water is collected for self-cleaning of the air outlet components. No external water source is required, and cleaning is convenient. It can also automatically detect whether the water tank is full of water before performing the cleaning action, which is intelligent.

[0096] In this embodiment, there is no specific limitation on the range of the third preset time. When the air conditioner is started and in cooling or dehumidification mode, after the last cleaning, the water channel is not dirty, so condensed water can be collected. When the humidity is high and the cooling setting temperature is low, condensed water is more likely to form, and the time can be shortened accordingly. In some preferred embodiments, the third preset time is 50-70 minutes, and in some specific embodiments, the third preset time is 60 minutes. After this period of water storage, the amount of water can meet the amount of water required for self-cleaning of the air outlet component.

[0097] In some specific embodiments, when the air conditioner is used for the first time, water suitable for the first self-cleaning of the air outlet component can be manually added to the water tank 2 before the air conditioner is started or before the air conditioner receives a self-cleaning command to ensure the amount of water for the self-cleaning of the air outlet component when it is first run.

[0098] like Fig.11 As shown, it should be pointed out that in the present embodiment, except in the water storage mode, the three-way valve assembly 3 connects the water tank 2 and the water outlet 1, in other modes, i.e., the normal mode, the three-way valve assembly 3 connects the drain pipe 6 and the water outlet 1 of the air-conditioning water receiving pan for drainage. Here, the normal mode includes the self-cleaning mode or other modes in which the air conditioner works normally.

[0099] Compared with the prior art, the air conditioner self-cleaning control method of the present invention utilizes the principle of condensation generated by the air conditioner. After the air conditioner performs automatic cleaning, it automatically collects and stores condensed water, and provides a clean water source when performing the cleaning action. It does not require an external water source, and is convenient for cleaning. It can also automatically detect whether the water tank is full of water before performing the cleaning action. It is intelligent and does not require disassembly of parts during the cleaning process, thereby improving the cleaning efficiency.

[0100] An embodiment of the present invention further provides an air conditioner self-cleaning control device, comprising a computer-readable storage medium storing a computer program and a processor, wherein when the computer program is read and executed by the processor, the air conditioner self-cleaning control method is implemented.

[0101] The advantages of the air conditioner self-cleaning control device described in the present invention and the air conditioner self-cleaning control method described in the present invention over the prior art are the same and will not be described in detail here.

[0102] An embodiment of the present invention further provides an air conditioner, including an air conditioner self-cleaning control system or an air conditioner self-cleaning control device.

[0103] In this embodiment, the air conditioner further includes a main controller. When the control switch assembly 7 detects that the water tank 2 is not full, a signal is sent to the main controller, and the main controller sends a warning signal to remind the user to manually add water until the water tank 2 is full and the self-cleaning command is executed. The present invention does not limit the specific model of the main controller, and any existing technology that can control the air conditioner to achieve the cleaning function in this embodiment can be used.

[0104] The advantages of the air conditioner described in the present invention and the air conditioner self-cleaning control system or the air conditioner self-cleaning control device over the prior art are the same and will not be repeated here.

[0105] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
