At the same time, a thermal insulation cotton is fixedly connected to the surface of the protective cover 2, which can insulate the condensed water in the water collecting pan 5, thereby avoiding the situation where condensed water is generated on the surface of the protective cover 2 and the ceiling is soaked, thereby improving the use effect of the fan coil unit 1.

[0024] Furthermore, the inner wall of the water collecting pan 5 is fixedly connected with an installation box 11, the cross-section of the installation box 11 is triangular, the drain pipe 3 is located in the installation box 11, and the interior of the installation box 11 is divided into a water flow chamber 17 and a collection chamber 16. The drain pipe 3 is located in the water flow chamber 17, and the setting of the collection chamber 16 stores impurities. The surface of the installation box 11 is fixedly connected with a first filter plate 8 which is arranged obliquely, and the inclined surface of the drain pipe 3 fits with the bottom of the first filter plate 8, so that the condensed water entering the drain pipe 3 can be filtered through the setting of the first filter plate 8, thereby preventing impurities from entering the drain pipe 3 and clogging the drain pipe 3, so that the condensed water cannot flow out and is always retained in the water collecting pan 5, thereby causing the device to overflow and soak the ceiling, thereby ensuring the use effect of the device.

[0025] The surface of the installation box 11 is slidably connected to a cover plate 6, which is located above the collecting chamber 16. The cover plate 6 can cover the impurities in the collecting chamber 16, thereby preventing the impurities in the collecting chamber 16 from flowing out again, thereby improving the use effect of the device. The surface of the cover plate 6 is fixedly connected to a first spring 18, and one end of the first spring 18 away from the cover plate 6 is fixedly connected to the surface of the installation box 11 for resetting the cover plate 6.

[0026] Furthermore, a mounting plate 9 and a scraper 10 are provided on the mounting box 11. The scraper 10 is rotatably connected to the mounting plate 9. The surface of the scraper 10 is in close contact with the surfaces of the first filter plate 8 and the cover plate 6, so as to scrape and push impurities on the surface of the first filter plate 8, thereby avoiding clogging of the first filter plate 8 by impurities, thereby affecting the condensate water from entering the drain pipe 3, and further ensuring the smooth flow of the condensate water.

[0027] A torsion spring 24 is fixedly connected to the surface of the scraper 10. One end of the torsion spring 24 away from the scraper 10 is fixedly connected to the inside of the mounting plate 9. When the scraper 10 and the mounting plate 9 are relatively vertical, the torsion spring 24 is in a twisted state.

[0028] Furthermore, a motor 4 is fixedly connected to the surface of the water receiving tray 5, and an output end of the motor 4 penetrates the surface of the water receiving tray 5 and is rotatably connected to the inside of the water receiving tray 5. One end of the output end of the motor 4 located inside the water receiving tray 5 is fixedly connected to a reciprocating screw 13, and an L-shaped movable plate 14 is threadedly connected to the surface of the reciprocating screw 13.

The extension rod 25 and the baffle 7 correspond to each other, and the extension rod 25 and the baffle 7 are at the same height, thereby ensuring that when the extension rod 25 moves, it can smoothly push the baffle 7, thereby ensuring the smooth operation of the device.

[0030] The end of the movable plate 14 away from the connecting rod 15 is fixedly connected with the push rod 12, and the push rod 12 passes through the surface of the installation box 11 and is slidably connected to the inside of the installation box 11. The inner wall of the drain pipe 3 is slidably connected with the second filter plate 21, and the holes of the second filter plate 21 are staggered with the holes of the first filter plate 8. The surface of the second filter plate 21 is fixedly connected with the extrusion rod 20, and the holes on the extrusion rod 20 and the first filter plate 8 correspond to each other. The extrusion rod 20 is conical, and the length of the extrusion rod 20 is the same as the thickness of the first filter plate 8, so that after the extrusion rod 20 is inserted into the first filter plate 8, the extrusion rod 20 will not protrude from the surface of the first filter plate 8, thereby avoiding the situation where the scraper 10 is blocked from sliding on the first filter plate 8.

[0031] Furthermore, a second spring 22 is fixedly connected to the bottom of the first filter plate 8, and one end of the second spring 22 away from the first filter plate 8 is fixedly connected to the surface of the second filter plate 21 for resetting the second filter plate 21. A lifting plate 23 is fixedly connected to the bottom of the second filter plate 21, and an extrusion groove 19 is provided on the surface of the lifting plate 23. The inner wall of the extrusion groove 19 is inclined, and half of the extrusion groove 19 passes through the surface of the lifting plate 23, and the surface of the push rod 12 contacts the inner wall of the extrusion groove 19.

[0032] Specifically, the motor 4 is started, and the moving plate 14 is driven to reciprocate on the reciprocating screw rod 13, and the connecting rod 15 and the push rod 12 are driven to reciprocate in the water receiving tray 5. When the connecting rod 15 and the push rod 12 move in the water receiving tray 5 in a direction away from the motor 4, the mounting plate 9 and the scraper 10 are driven to slide on the surface of the first filter plate 8, and the push rod 12 squeezes the inclined surface of the inner wall of the extrusion groove 19, thereby pushing the lifting plate 23 to slide and rise in the drain pipe 3, thereby driving the extrusion rod 20 to rise in the water flow chamber 17, and compressing the second spring 22, and inserting the extrusion rod 20 into the hole of the first filter plate 8, pushing the impurities in the hole of the first filter plate 8, and retaining them on the surface of the first filter plate 8, and then as the push rod 12 and the connecting rod 15 continue to slide, the mounting plate 9 is driven to push the scraper 10 to scrape off the impurities on the surface of the first filter plate 8, and then as the mounting plate 9 and the scraper 10 continue to move, the extension rod 25 and the baffle 7 are moved together. The first spring 18 is stretched and the mounting plate 9 and the scraper 10 are moved upwards to open the collecting chamber 16. The scraper 10 is located above the collecting chamber 16. At this time, under the elastic force of the torsion spring 24, the scraper 10 and the mounting plate 9 are kept on the same vertical plane. The impurities on the scraper 10 fall into the collecting chamber 16 and are collected, thereby preventing the impurities from being always retained in the water receiving tray 5. As the condensed water flows, the first filter plate 8 is blocked, and the condensed water cannot be discharged and overflows. Therefore, when the device is in use, the impurities in the water receiving tray 5 can be always collected and scraped. Therefore, the impurities are prevented from clogging the drain pipe 3, which makes it impossible for the condensed water to be discharged, and the device overflows, which affects the surrounding environment. Therefore, the use effect of the device is improved, and it has high promotion value and practicality.

[0033] Working principle: The motor 4 is started, which drives the mounting plate 9 and the scraper 10 to slide on the surface of the first filter plate 8, and the push rod 12 squeezes the inclined surface of the inner wall of the extrusion groove 19, thereby driving the extrusion rod 20 to rise in the water flow chamber 17, and at the same time, the extrusion rod 20 is inserted into the hole of the first filter plate 8, pushing the impurities in the hole of the first filter plate 8, and retaining them on the surface of the first filter plate 8, and then as the push rod 12 and the connecting rod 15 continue to slide, the mounting plate 9 is driven to push the scraper 10 to scrape the impurities on the surface of the first filter plate 8, and when the extension rod 25 pushes the baffle 7, the cover plate 6 is driven to slide on the surface of the mounting box 11 to open the collecting chamber 16, and then when the scraper 10 is located above the collecting chamber 16, under the elastic force of the torsion spring 24, the scraper 10 and the mounting plate 9 remain on the same vertical plane, so that the impurities on the scraper 10 fall into the collecting chamber 16 and the impurities are collected.
