Therefore, they cannot be understood as a limitation on the present invention.

[0023] like Figures 1 to 3As shown, an air conditioner maintenance device includes an air conditioner outer case 1 and a support plate 4. A dustproof net 2 is hinged on the front of the air conditioner outer case 1, an exhaust fan 3 is rotatably installed on the inner wall surface of the air conditioner outer case 1, a spray assembly 5 and a movable cleaning mechanism 8 are provided on the surface of the support plate 4, a fan brush 6 is fixedly installed on the bottom surface of the support plate 4, a second motor 9 is fixedly installed on the top surface of the support plate 4, the output end of the second motor 9 passes through the surface of the support plate 4, and the output end of the second motor 9 is fixedly connected to the fan 7.

[0024] Specifically, when the air-conditioning outdoor unit needs maintenance, the top cover of the air-conditioning outdoor unit is opened, the support plate 4 is placed on the surface of the air-conditioning outdoor unit case 1 and engaged, and cleaning liquid or tap water or other liquids are sprayed on the surface of the exhaust fan 3 inside the air-conditioning outdoor unit case 1 through the spray assembly 5, and the fan 7 is driven to rotate by the rotation of the output end of the second motor 9. The wind force generated by the fan 7 can accelerate the volatilization of the liquid on the surface of the exhaust fan 3. At the same time, the exhaust fan 3 can rotate under the action of the wind force generated by the fan 7. After the exhaust fan 3 rotates, each blade of the exhaust fan 3 can contact the fan brush 6. During the rotation of the exhaust fan 3, friction is generated with the fan brush 6 to The dust on the surface of the exhaust fan 3 is cleaned. When the surface of the exhaust fan 3 is sprayed and wiped, some liquid and dust will fall to the bottom of the inner wall of the air-conditioning outer case 1. The dust inside the air-conditioning outer case 1 can be cleaned by moving the cleaning mechanism 8. When the dust on both sides is concentrated in the middle of the bottom surface of the air-conditioning outer case 1, the dust can be cleaned out from the inside of the air-conditioning outer case 1 by opening the dustproof net 2, which is beneficial to ensure the use effect and service life of the air conditioner, and avoids the maintenance personnel from extending their arms into the inside of the air-conditioning outer case 1 from above for maintenance work. The maintenance work is more convenient, which is conducive to the smooth progress of the air-conditioning maintenance work.

[0025] like Figures 1 to 3 As shown, the fan brush 6 has an inverted U-shaped structure. There are two fan brushes 6 and they are arranged on the left and right sides. The fan 7 can contact the inner side surface of the fan brush 6.

[0026] Specifically, the fan brush 6 is in an inverted U-shaped structure, which facilitates cleaning of the front and rear sides of the fan 7, making the cleaning of the fan 7 more thorough, which is beneficial to ensuring the use effect and service life of the air conditioner.

[0027] like Figure 1 As shown, the bottom surface of the dustproof net 2 is hinged to the surface of the air conditioner outer case 1, and the upper end of the dustproof net 2 is fixed to the surface of the air conditioner outer case 1 by screws.

[0028] Specifically, when it is necessary to centrally clean the dust inside the air-conditioning outer case 1, the dust-proof net 2 can be rotated by removing the screws at the upper end of the dust-proof net 2 from the surface of the air-conditioning outer case 1. At this time, space is left for centralized cleaning of the dust, which is convenient for maintenance personnel to clean out the dust from the front of the air-conditioning outer case 1, avoiding the maintenance personnel from extending their arms into the air-conditioning outer case 1 from above to perform maintenance work. The maintenance work is more convenient, which is conducive to the smooth progress of the air-conditioning maintenance work.

[0029] like Figures 1 to 3 As shown, the support plate 4 includes two fixed legs 402 , which can be respectively engaged with the two side walls of the air conditioner outer case 1 , and the support plate body 401 is fixedly installed on the top surface of the fixed legs 402 .

[0030] Specifically, by engaging the air conditioner outer case 1 with the fixing legs 402, the support plate body 401 can be fixed and connected to the air conditioner outer case 1, which is beneficial to the stability of the overall structure and facilitates smooth air conditioner maintenance work.

[0031] like Figures 1 to 3 As shown, the spray assembly 5 includes a cleaning liquid storage tank 501, which is fixedly installed on the top surface of the support plate body 401. A spray head 502 is fixedly installed on the bottom surface of the cleaning liquid storage tank 501, and the spray head 502 is set through the surface of the support plate body 401.

[0032] Specifically, by injecting cleaning liquid or tap water or other liquid into the cleaning liquid storage tank 501 and spraying the liquid onto the surface of the exhaust fan 3 through the spray head 502, it is convenient to clean the dust on the surface of the exhaust fan 3. The maintenance personnel do not need to hold a spray gun and reach into the interior of the air conditioner outer case 1 to clean the exhaust fan 3, making the cleaning of the exhaust fan 3 easier and more convenient.

[0033] like Figures 1 to 3 As shown, the mobile cleaning mechanism 8 includes a fixed block 801 and a slide 802. The fixed block 801 is fixedly installed on the top surface of the support plate body 401. There are two fixed blocks 801 and they are respectively arranged on the left and right sides of the cleaning liquid storage tank 501. The slide 802 is opened on the top surface of the support plate body 401. There are two slides 802 and they are respectively arranged on the left and right sides of the cleaning liquid storage tank 501. The opposite sides of the two fixed blocks 801 are fixedly installed with a first motor 803. A threaded rod 804 is rotatably installed between the opposite surfaces of the fixed block 801 and the cleaning liquid storage tank 501. The threaded rod 804 is fixedly connected to the output end of the first motor 803. A sliding rod 805 is threadedly sleeved on the surface of the threaded rod 804. The sliding rod 805 is slidably installed on the inner wall surface of the slide 802, and a brush head 806 is fixedly installed on the bottom surface of the sliding rod 805.

[0034] Specifically, the output end of the first motor 803 on the surface of the fixed block 801 rotates to drive the threaded rod 804 to rotate, thereby driving the sliding rod 805, which is threadedly mounted on the surface of the threaded rod 804 and slidably installed on the inner wall surface of the slide groove 802, to slide left and right, and then drive the brush head 806 to slide left and right along the inner wall surface of the air-conditioning outer case 1, so as to facilitate the cleaning of the dust at the bottom of the air-conditioning outer case 1, and concentrate the dust on both sides to the middle of the bottom surface of the inner wall of the air-conditioning outer case 1, so as to facilitate the subsequent cleaning of the dust from the inside of the air-conditioning outer case 1, which is conducive to the smooth progress of maintenance work.

[0035] When the fan 7 is in the air, the fan 7 is rotated, and the wind force generated by the fan 7 can accelerate the volatilization of the liquid on the surface of the exhaust fan 3. At the same time, the exhaust fan 3 can rotate under the action of the wind force generated by the fan 7, so that each blade of the exhaust fan 3 can contact and generate friction with the fan brush 6, which is convenient for cleaning the dust on the surface of the exhaust fan 3. The dust inside the outer case 1 of the air conditioner can be cleaned from both sides to the middle by moving the cleaning mechanism 8. The dust inside the outer case 1 of the air conditioner can be cleaned out by opening the dustproof net 2, which is beneficial to ensuring the use effect and service life of the air conditioner and avoiding the maintenance personnel from extending their arms into the outer case 1 of the air conditioner from above for maintenance work. The maintenance work is more convenient and is conducive to the smooth progress of the air conditioner maintenance work.
