[0029] Furthermore, the condensate pan 1 collects the condensate generated during the operation of the heat exchange coil 2 above, and a water-proof strip 205 is installed inside the condensate pan 1 to prevent water vapor from corroding the heat exchange coil 2.

[0030] To prevent dust and other debris from clogging the air inlet after prolonged use and affecting the cooling effect of the fan coil unit, a cleaning mechanism is installed, such as... Figure 1 and Figures 3-4 The cleaning mechanism includes a cleaning brush 3, which performs the action of cleaning dust and debris clogging the surface of the device.

[0031] The cleaning mechanism also includes a cleaning box 301.

[0034] Furthermore, the drive motor 304 drives the movable bracket 306 to move along the length of the movable screw 305 via the movable screw 305.

[0035] A cleaning shaft 307 is rotatably connected to the surface of the movable bracket 306. The surface of the cleaning shaft 307 is slidably connected to the inner wall of the cleaning tank 301. The surface of the cleaning shaft 307 is fixedly connected to the surface of the cleaning brush 3. The surface of the cleaning brush 3 is slidably connected to the surface of the filter tank 303.

[0036] Furthermore, the cleaning motor 309 located below the cleaning tank 301 drives the cleaning brush 3 to rotate via the cleaning shaft 307 to clean the surface of the filter tank 303.

[0039] By setting up a cleaning mechanism, the cleaning brush 3 cleans the dust and debris clogging the surface of the device, preventing dust and other debris from clogging the air inlet after long-term use and affecting the cooling effect of the fan coil unit. This solves the technical problem that a large amount of dust will accumulate on the filter screen of the existing fan coil unit after long-term use, reducing the air intake of the fan coil unit.

[0040] Working principle:

[0041] Before use, the refrigeration motor 203 installed on the surface of the heat exchange box 202 drives the refrigeration fan 201 to start working. Air from outside the cleaning box 301 enters the interior of the cleaning box 301 through the dustproof plate 302. The air inlet of the refrigeration fan 201 sends the air from inside the cleaning box 301 into the heat exchange box 202, cooling the heat exchange coils 2 installed inside the heat exchange box 202. The condensate produced after heat exchange by the heat exchange coils 2 is collected through the condensate tray 1 installed at the bottom of the heat exchange box 202. The bottom of the condensate tray 1 is supported by multiple water-proof strips 205 to prevent the accumulated condensate from corroding the structural components. The condensate accumulated inside the condensate pan 1 is discharged through the drain pipe 206 at the bottom of the condensate pan 1. A drain plug 207 is installed at one end of the drain pipe to control the discharge of the drain pipe 206. After long-term use, dust carried by the outside air will clog the filter tank 303 when passing through the dustproof plate 302, reducing the air intake of the fan coil unit and affecting the cooling effect of the fan coil unit. The moving motor 304 installed on the surface of the cleaning box 301 drives the moving bracket 306 to move along the opening direction of the filter tank 303 through the moving screw 305. The surface of the moving bracket 306 is rotatably connected to the cleaning shaft 307. Shaft 307 prevents the movable support 306 from shifting when the movable screw 305 rotates. The cleaning motor 309, located below the cleaning tank 301 and mounted on the surface of the mounting plate 308, drives the cleaning shaft 307 to rotate. This rotation causes the cleaning brush 3 on the surface of the cleaning shaft 307 to clean the surface of the filter tank 303. The mounting plate 308 moves synchronously with the cleaning brush 3, preventing the cleaning motor 309 from rotating on its own during operation. The cleaning motor 309 and the movable motor 304 work together to move and clean the surface of the filter tank 303, removing dust and debris clogging the surface of the filter tank 303. The cleaning brush 3 is equipped with a diversion pipe 313 at the rear. One end of the diversion pipe 313 is connected to the compressed air pipe through a connecting cylinder. Multiple high-pressure air nozzles 315 are horizontally arranged on the surface of the diversion pipe 313 to blow air to clean the filter tank 303 after it has been cleaned by the cleaning brush 3 and to perform reverse rinsing of the filter tank 303. The lifting cylinder 310 on the upper surface of the cleaning box 301 drives the lifting slider 312 to slide up and down along the surface of the guide rod 311. The surface of the lifting slider 312 is fixedly connected to the surface of the diversion pipe 313, which drives the diversion pipe 313 to move up and down to circulate and clean the filter tank 303 on the surface of the dustproof plate 302.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
