DETAILED DESCRIPTION

[0016] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0017] The embodiment of the present utility model: Figure 1 and Figure 2 As shown, a ceiling-mounted air conditioner automatic cleaning device includes a flushing component 1. A lifting mechanism is provided in the ceiling-mounted air conditioner main body shell 2. The lifting mechanism is located on one side of the air conditioner radiator 3. The flushing component 1 is installed on the lifting mechanism. The flushing component 1 is connected to the water source through a water pipe 4.

[0018] By setting up a lifting mechanism and a flushing component 1, the flushing component 1 can be driven up and down by the lifting mechanism to achieve thorough flushing of the air-conditioning radiator 3, so that there is no need for workers to climb high to clean the air-conditioning radiator 3, which solves the safety hazards of manual climbing and improves cleaning efficiency.

[0019] In a specific embodiment, the lifting mechanism includes a waterproof motor 5 and two sets of chain transmission assemblies, the two sets of chain transmission assemblies are arranged on both sides of the ceiling-mounted air-conditioning host housing 2, the flushing assembly 1 is connected to the two sets of chain transmission assemblies, and the output shaft of the waterproof motor 5 is connected to one of the chain transmission assemblies.

[0020] The structures of the two sets of chain transmission assemblies are exactly the same. The chain transmission assemblies include a first sprocket 6, a chain 7 and a second sprocket. The first sprocket 6 is rotatably installed in the upper part of the ceiling-mounted air-conditioning main unit housing 2, and the second sprocket is rotatably installed in the lower part of the ceiling-mounted air-conditioning main unit housing 2. The chain 7 connects the first sprocket 6 and the second sprocket, and the rotating shaft of one of the second sprockets is connected to the output shaft of the waterproof motor 5.

[0021] When the waterproof motor 5 is working, it drives the second sprocket to rotate, and the rotation of the second sprocket drives the first sprocket 6 to rotate through the chain 7. During the movement of the chain 7, the flushing component 1 is installed on the chain 7. When the chain 7 moves, it drives the flushing component 1 to move and change its height, thereby realizing flushing of different height positions of the air conditioner radiator 3.

[0022] Furthermore, limit switches 8 are provided at the upper and lower parts of the housing 2 of the ceiling-mounted air-conditioning host, and the waterproof motor 5 and the limit switch 8 are electrically connected to the control module of the ceiling-mounted air-conditioning host.

[0023] The control module of the ceiling-mounted air conditioner has a programmable logic controller (PLC). By rewriting the program of the PLC, the control module of the ceiling-mounted air conditioner can control the working state of the waterproof motor 5 and collect signals from the limit switch 8. This eliminates the need for an additional control module, reducing modification costs.

[0024] The flushing assembly 1 includes a flushing pipe 9 and a nozzle 10 . Both ends of the flushing pipe 9 are fixedly connected to the two chains 7 , and a plurality of nozzles 10 are evenly distributed on the flushing pipe 9 .

[0025] The flushing pipe 9 is arranged horizontally and preferably remains horizontal during the lifting process. To keep the flushing pipe 9 horizontal during movement, the second sprockets of the two chain drive assemblies can be connected via a connecting shaft. In this way, the chains 7 at both ends of the flushing pipe 9 can move synchronously, allowing the flushing pipe 9 to always remain horizontal. If the connecting shaft is not provided, the lifting of the flushing pipe 9 will not be affected; only one end will be slightly higher than the other.

[0026] An electric valve 11 is provided on the water pipe 4 and is electrically connected to a control module of the ceiling-mounted air-conditioning host.

[0027] Further, a water retaining bar 12 is provided on the bottom plate in the ceiling-mounted air conditioner mainframe housing 2. The water retaining bar 12 is provided near the condensate drain pipe 13 of the air conditioner mainframe, so that the sewage after flushing the air conditioner radiator 3 can be discharged through the condensate drain pipe 13.

[0028] The working principle of the present utility model is as follows: during operation, the control module of the ceiling-mounted air-conditioning host is programmed to control the working status of the electric valve 11 and the waterproof motor 5. When the electric valve 11 is opened, the water source supplies water to the flushing pipe 9 through the water pipe 4, and the water is sprayed to the air-conditioning radiator 3 through the nozzle 10. The waterproof motor 5 drives the second sprocket to rotate, and the second sprocket drives the chain 7 to move. The movement of the chain 7 drives the flushing pipe 9 to rise. During the rising process of the flushing pipe 9, the nozzle 10 can flush the air-conditioning radiator 3 at different heights. When the flushing pipe 9 rises to a preset height, it contacts the limit switch 8 provided on the upper part of the ceiling-mounted air-conditioning host housing 2. The limit switch 8 sends a signal to the control module, and the control module controls the waterproof motor 5 to rotate in the opposite direction, and the flushing pipe 9 starts to move downward. When the flushing pipe 9 contacts the limit switch 8 at the lower part of the ceiling-mounted air-conditioning host housing 2, the limit switch 8 sends a signal to the control module, and the control module controls the waterproof motor 5 to rotate in the opposite direction, thus completing a working cycle. After completing the preset number of working cycles, the control module controls the waterproof motor 5 to stop and the electric valve 11 is closed.

[0029] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
