[0089] The following will be described in conjunction with Figures 1 to 6 The embodiments of the present application are further described in detail. The following embodiments are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0090] In a first aspect, as Figure 1 The present application provides a cleaning method of an air conditioner, comprising the following steps:

[0091] Step S1, in response to the dirt signal of the filter screen 14.

[0092] Step S2, generating a cleaning strategy according to the dirt signal of the filter screen 14.

[0093] Step S3, cleaning the filter screen 14 according to the cleaning strategy.

[0094] As Figure 6As shown, the air conditioner of the present application is a cylindrical air conditioner, which comprises a shell 12, a filter screen 14 and a cleaning mechanism 10. The shell 12 is provided with an air inlet and an air outlet, and the air inlet and the air outlet are opposite to each other. The filter screen 14 is arranged at the air inlet and can move between the air inlet and the air outlet. Optionally, a driving mechanism 16 is arranged in the shell 12, and the filter screen 14 changes the position through the driving mechanism 16. The cleaning mechanism 10 is arranged on the inner wall of the shell 12 and located between the air inlet and the air outlet. When the filter screen 14 moves between the air inlet and the air outlet, the cleaning mechanism 10 can clean the filter screen 14.

[0095] In an optional embodiment provided by the present application, step S1 specifically comprises:

[0096] Step S1.1, obtaining the control instruction sent by the user.

[0097] Step S1.2, determining that the control instruction at least identifies the cleaning information of the filter screen 14, and generating the dirt signal according to the control instruction.

[0098] When the air conditioner is running, the filter screen 14 is shielded at the air inlet and used to filter the airflow entering from the air inlet. The user can visually observe the dirt condition of the filter screen 14, and when the user thinks that the dirt of the filter screen 14 needs to be cleaned, sends a control instruction to the air conditioner, which includes the cleaning information of the filter screen 14. After the air conditioner receives the control instruction, the dirt signal is generated. The control instruction can include the cleaning information of the filter screen 14, the temperature information of the air conditioner and the humidity information of the air conditioner.

[0099] In another optional embodiment provided by the present application, a pressure sensor is arranged at the air inlet of the air conditioner, and step S1 specifically comprises:

[0100] Step S1.3, obtaining the pressure parameter monitored by the pressure sensor.

[0101] Step S1.4, determining that the cleaning degree of the filter screen 14 identified by the pressure parameter meets the preset cleaning threshold, and generating the dirt signal according to the pressure parameter.

[0102] The pressure parameter is the parameter when the filter screen 14 is arranged at the air inlet.

[0103] When the air conditioner is in the non-cleaning state, the filter screen 14 continuously stays at the air inlet position. The detection end of the pressure sensor is arranged at the windward side and the leeward side of the filter screen 14, respectively, for detecting the air pressure of the windward side and the leeward side, calculating the difference between the air pressure of the windward side and the leeward side, and determining that the absolute value of the difference is greater than or equal to the first air pressure difference when the cleaning degree of the filter screen 14 meets the preset cleaning threshold, and then generating the dirt signal according to the pressure parameter.

[0104] AsFigure 2 As shown in the above embodiment, step S3 specifically comprises:

[0105] Step S3.1, rotate the filter screen 14 to an initial cleaning position, and adjust the cleaning part 106 to an initial position.

[0106] Step S3.2, move the cleaning part 106 from the initial position to the water tank 102 for medium replenishment.

[0107] Step S3.3, control the cleaning part 106 to return from the position of the water tank 102 to the initial position, and spray medium to the filter screen 14 in the process.

[0108] Step S3.4, determine that the cleaning part 106 reaches the initial position, and rotate the filter screen 14 to the next cleaning position.

[0109] Step S3.5, repeat the above steps until all cleaning positions of the filter screen 14 are cleaned.

[0110] The initial cleaning position is the position where the filter screen 14 is cleaned for the first time, and the initial position is the farthest end of the cleaning part 106 from the water tank 102 in the extension direction of the slide rail 104.

[0111] The cleaning mechanism 10 comprises a water tank 102, a cleaning part 106, and a slide rail 104. The water tank 102 is arranged on the inner wall of the shell 12 and is close to the ground. An opening is formed on the upper side of the water tank 102, and the water tank 102 contains cleaning medium inside. The slide rail 104 is arranged on the inner wall of the shell 12 and is arranged perpendicular to the moving direction of the filter screen 14. One end of the slide rail 104 extends to the water tank 102. The cleaning part 106 is in sliding cooperation with the slide rail 104, and the moving direction of the cleaning part 106 is perpendicular to the moving direction of the filter screen 14. The cleaning part 106 is provided with a first sensing part for detecting the dirt degree of the filter screen 14. When the cleaning part 106 moves into the water tank 102, the medium can be replenished from the water tank 102. The cleaning part 106 is provided with a nozzle for spraying medium to the filter screen 14.

[0112] Further, step S3.2 specifically comprises:

[0113] Step S3.2.1, in the process of moving the cleaning part 106 to the water tank 102, the dirt degree of the filter screen 14 is acquired in real time.

[0114] Step S3.2.2, according to the dirt degree of the filter screen 14, the medium spraying amount of the cleaning part is determined.

[0115] Further, step S3.2.1 specifically comprises:

[0116] Step S3.2.1.1, in the process of moving the cleaning part 106 to the water tank 102, a set amount of detection rays are sent.

[0117] Step S3.2.1.2, obtaining the returned amount of detection rays, and determining the difference value according to the set amount and the returned amount.

[0118] Step S3.2.1.3, determining the dirt degree of the filter screen 14 according to the difference value.

[0119] Specifically, the filter screen 14 is moved from the air inlet to an initial cleaning position between the air inlet and the air outlet, and the cleaning part 106 is opposite to one side edge of the filter screen 14 at this time. The cleaning part 106 is usually in an empty state without containing medium inside. The cleaning part 106 is lifted to be away from the water tank 102 in the empty state.

[0120] Optionally, the first sensing part is an infrared sensor. The cleaning part 106 is moved from the initial position to the position of the water tank 102, and during the movement, the infrared sensor sends a set amount of infrared rays to the filter screen 14, and receives the returned infrared rays of the filter screen 14. The difference value between the set amount and the returned amount is calculated, and the dirt degree of the filter screen 14 is determined according to the difference value. If it is determined that the dirt degree meets the preset condition, the medium is supplemented into the cleaning part 106 from the water tank 102 after the cleaning part 106 reaches the water tank 102. If it is determined that the dirt degree does not meet the preset condition, the empty state of the cleaning part 106 is maintained after the cleaning part 106 reaches the water tank 102. The determination that the dirt degree meets the preset condition includes: determining that the difference value is greater than or equal to a set proportion of the set amount, and then determining that the dirt degree meets the preset condition. The determination that the dirt degree does not meet the preset condition includes: determining that the difference value is less than the set proportion of the set amount, and then determining that the dirt degree does not meet the preset condition. Optionally, the set proportion is 20%.

[0121] After the medium supplement is completed, the cleaning part 106 is moved from the position of the water tank 102 to the initial position, and during the movement, the nozzle is opened to spray the medium to the filter screen 14. Optionally, after the cleaning part 106 reaches the initial position, all the medium in the cleaning part 106 has been sprayed out. The cleaning part 106 reaches the initial position, and the filter screen 14 is rotated to the next cleaning position. The above steps are repeatedly continued until all the cleaning positions of the filter screen 14 are cleaned.

[0122] Optionally, the step S3 specifically includes:

[0123] Step S3.6, rotating the filter screen 14 to the initial cleaning position, and adjusting the cleaning part 106 to the initial position.

[0124] Step S3.7, reciprocating the cleaning part 106 between the initial position and the position of the water tank 102 until all the cleaning positions of the filter screen 14 are cleaned.

[0125] Step S3.8, rotating the filter screen 14 from the initial cleaning position to the final cleaning position until all the cleaning positions of the filter screen 14 are cleaned.

[0126] In the above embodiment, step S3.7 specifically includes:

[0127] Moving the cleaning part 106 from the initial position to the water tank 102 for medium replenishment, and moving the cleaning part 106 from the position of the water tank 102 to the initial position, and spraying medium to the filter screen 14.

[0128] In order to ensure the cleaning effect, after all the cleaning positions of the filter screen 14 are cleaned, the cleaned filter screen 14 is re-inspected, and the dirt found in the re-inspection is treated accordingly. Based on this, the present application also provides an embodiment, as shown in Figure 3 The steps after step S3 further include the following steps:

[0129] Step S4, rotating the filter screen 14 to the initial cleaning position, and adjusting the cleaning part 106 to the initial position.

[0130] Step S5, moving the cleaning part 106 from the initial position to the water tank 102 for medium replenishment.

[0131] Step S6, acquiring the dirt form feature of the filter screen 14 in real time during the process of moving the cleaning part 106 to the water tank 102.

[0132] Step S7, generating a secondary cleaning strategy according to the dirt form feature.

[0133] Step S8, controlling the operation of the cleaning part 106 according to the secondary cleaning strategy during the process of moving the cleaning part 106 from the position of the water tank 102 to the initial position.

[0134] Step S9, determining that the cleaning part 106 reaches the initial position, and rotating the filter screen 14 to the next cleaning position.

[0135] Step S10, repeating the above steps until all the cleaning positions of the filter screen 14 are cleaned.

[0136] Specifically, the filter screen 14 is moved from the air inlet to the initial cleaning position between the air inlet and the air outlet, at this time the cleaning part 106 is opposite to one side edge of the filter screen 14. The cleaning part 106 is lifted to move away from the water tank 102 to the initial position in an empty state. The cleaning part 106 is moved from the initial position to the water tank 102, during the moving process, a set amount of infrared rays is sent to the filter screen 14, and the return amount of the infrared rays is acquired from the filter screen 14. The difference between the set amount and the return amount is calculated, and the dirt form feature is determined according to the difference. The secondary cleaning strategy is generated according to the dirt form feature. The cleaning part 106 reaches the water tank 102, and the medium is replenished from the water tank 102 to the cleaning part 106.

[0137] The cleaning part 106 is moved from the position of the water tank 102 to the initial position, and during the movement, the cleaning part 106 operates according to the secondary cleaning strategy. When it is determined that the cleaning part 106 reaches the initial position, the filter screen 14 is rotated to the next cleaning position.

[0138] The above steps are repeated until the secondary cleaning of all cleaning positions of the filter screen 14 is completed.

[0139] Wherein, as shown in Figure 4 Step S7 specifically includes:

[0140] Step S7.1, determining that the dirt form feature is the first form feature, generating a secondary cleaning strategy of point cleaning.

[0141] Step S7.2, determining that the dirt form feature is the second form feature, generating a secondary cleaning strategy of overall cleaning.

[0142] Wherein, the first form feature indicates that the dirt area is less than or equal to a preset area, and the second form feature indicates that the dirt area is greater than the preset area.

[0143] Further, step S7.1 specifically includes:

[0144] Step S7.1.1, determining that the dirt form feature is the first form feature.

[0145] Step S7.1.2, obtaining a first dirt position on the filter screen 14 indicating the first form feature of the dirt.

[0146] Step S7.1.3, generating a secondary cleaning strategy according to the first dirt position.

[0147] Wherein, the secondary cleaning strategy at least includes stopping the cleaning part 106 at each first dirt position and performing point cleaning on the filter screen 14.

[0148] Step S7.2 specifically includes:

[0149] Step S7.2.1, determining that the dirt form feature is the second form feature.

[0150] Step S7.2.2, obtaining a second dirt position on the filter screen 14 indicating the second form feature of the dirt.

[0151] Step S7.2.3, generating a secondary cleaning strategy according to the second dirt position.

[0152] Wherein, the secondary cleaning strategy at least includes controlling the cleaning part 106 to clean the filter screen 14 according to the contour of the second dirt position.

[0153] Specifically, as the cleaning unit 106 moves from its initial position to the water tank 102, the infrared sensor continuously sends a set amount of infrared light to the filter 14 and receives the returned infrared light from the filter 14. The difference between the set amount and the returned amount is calculated. Whenever the difference is determined to be greater than or equal to a set percentage of the set amount, the corresponding location of dirt is obtained, along with the corresponding duration. During one movement of the cleaning unit 106 from its initial position to the water tank 102, all durations are accumulated to obtain the cumulative duration.

[0154] If the cumulative duration is less than the set duration, it means the dirty area is less than the preset area, and the dirt is scattered. Therefore, the dirt morphology is determined to be the first morphology. The first dirty location on the filter 14 is obtained, and a secondary cleaning strategy is generated based on the first dirty location. This secondary cleaning strategy involves stopping the cleaning unit 106 at each first dirty location for a set time and performing targeted cleaning on the filter 14.

[0155] If the cumulative duration is greater than or equal to the set duration, it means that the dirty area is greater than or equal to the preset area, and the dirt is in block form. Therefore, the dirt morphology is determined to be the second morphology. The second dirt position on the filter 14 is obtained, and a secondary cleaning strategy is generated based on the second dirt position. The first and last appearance positions of the second dirt position are used as the outline of the second dirt position. The secondary cleaning strategy involves the cleaning unit 106 reciprocating within the outline of the second dirt position a set number of times to perform a comprehensive cleaning of the filter 14.

[0156] Secondly, such as Figure 5 As shown, the present invention also provides a control device for an air conditioner, comprising: a signal response module 20, a strategy generation module 22, and a strategy execution module 24. The signal response module 20 is used to respond to a dirt signal from the filter 14.
