DETAILED DESCRIPTION

[0021] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0022] See also Figure 1-2 The utility model provides a dustproof structure of air-cooled refrigeration equipment, including a cabinet 1, a fan unit 2 and a self-cleaning dustproof device 3. The fan unit 2 is installed on the side wall of the cabinet 1, and the self-cleaning dustproof device 3 is arranged outside the fan unit 2.

[0023] See also Figure 3-4 The self-cleaning dustproof device 3 in the utility model includes a connecting frame 31, a dustproof grid 32, a door opener 33, a linear module 34, a controller 35, a roller group 36 and a clamping mechanism 37. The connecting frame 31 is screwed to the side wall of the cabinet 1, and the connecting frame 31 covers the outside of the fan unit 2. The dustproof grid 32 is hingedly installed on the right side of the inner side of the connecting frame 31. The dustproof grid 32 can be closed into the inner side of the connecting frame 31. The door opener 33 is installed in the middle of the right side of the connecting frame 31, and the door opener 33 The end of the driving connecting rod is hinged to the dustproof grid 32, and the dustproof grid 32 is flipped and opened and closed by the door opener 33. A linear module 34 is installed at the top right end of the connecting frame 31. The linear module 34 is perpendicular to the top edge of the connecting frame 31. A controller 35 is installed on the upper right side of the connecting frame 31, wherein the door opener 33 and the linear module 34 are both connected to the controller 35 line and are centrally controlled by the controller 35. The bottom moving end of the linear module 34 is connected to the roller group 36 through the clamping mechanism 37.

[0024] To further explain, after the door opener 33 controls the dustproof grid 32 to be fully opened, the dustproof grid 32 is located directly below the linear module 34 and is consistent with its orientation angle. At this time, the linear module 34 can control the roller group 36 to move and clamp to both sides of the dustproof grid 32, thereby cleaning the inside and outside surfaces of the dustproof grid 32.

[0025] To further illustrate, the roller set 36 is consistent in height with the dustproof grid 32 , and the roller set 36 matches the size of the dustproof grid 32 , ensuring that the roller set 36 can move to cover every corner of the dustproof grid 32 , and it is not easy to leave dead corners for cleaning.

[0026] To further illustrate, the travel distance of the roller set 36 is greater than the horizontal width of the dustproof grid 32, ensuring that the roller set 36 can move to cover every corner of the dustproof grid 32, and it is not easy to leave a dead corner for cleaning.

[0027] See also Figure 5 The clamping mechanism 37 of the utility model includes a connecting seat 371, a slide bar 372, a slide seat 373 and a return spring 374. The connecting seat 371 is screwed to the bottom movable end of the linear module 34. The inner cavity at the bottom of the connecting seat 371 is horizontally installed with a slide bar 372. The inner cavity at the bottom of the connecting seat 371 is slidably connected to the slide seat 373 by a slide rail, and the slide seat 373 is movably sleeved on the surface of the slide bar 372. There are two slide seats 373, and the slide seats 373 are symmetrically distributed at the left and right ends of the slide bar 372. A return spring 374 is respectively provided, and both ends of the return spring 374 are connected to the connecting seat 371 and the sliding seat 373 respectively. The roller group 36 consists of two cleaning rollers 361 of the same size, and the two cleaning rollers 361 are respectively installed at the bottom of the two sliding seats 373, wherein the top of the cleaning roller 361 is rotatably connected to the sliding seat 373, and the two connecting seats 371 are pushed to move toward each other by the return spring 374, so that the roller group 36 is folded, ensuring that the two cleaning rollers 361 can fit tightly on the inner and outer surfaces of the dustproof grid 32 to ensure the cleaning effect.

[0028] Further description, the cleaning roller 361 is a brush roller, and the length of the bristles on the surface of the cleaning roller 361 is at least 1 cm, so that the cleaning roller 361 can clear the mesh of the dustproof grid 32 through the bristles, and the cleaning effect is good.

[0029] Here’s how it works:

[0030] First, before use, the controller 35 is first connected to the cooling system of the cabinet 1 for centralized control.

[0031] Second, during normal use, the door opener 33 controls the dustproof grid 32 to flip and close into the inner side of the connecting frame 31, so that the dustproof grid 32 covers the outside of the fan unit 2. The dustproof grid 32 intercepts dust particles in the air to prevent dust from being blown into the interior of the cabinet 1 by the fan unit 2, thereby playing a dustproof role.

[0032] Third, after a period of use, a layer of dust will adhere to the surface of the dustproof grid 32, causing the mesh to be blocked, thereby reducing the ventilation volume. When cleaning is required, a cleaning command is first issued to the controller 35, and the door opener 33 will first control the dustproof grid 32 to flip outward and open, so that the roller group 36 and the dustproof grid 32 are in the same direction, and then the linear module 34 controls the roller group 36 to move back and forth along its track. When the roller group 36 passes the position of the dustproof grid 32, the two cleaning rollers 361 of the roller group 36 will respectively fit on the inner and outer surfaces of the dustproof grid 32 and move to sweep away the dust adhered to the surface of the dustproof grid 32. Both the inner and outer surfaces of the dustproof grid 32 can be cleaned to further improve its cleaning effect. Then the linear module 34 controls the roller group 36 to move and reset along its track, and the door opener 33 controls the dustproof grid 32 to flip and close into the inner side of the connecting frame 31, thereby completing the cleaning process.

[0033] Fourth, by setting a clamping mechanism 37 on the top of the roller group 36, the two cleaning rollers 361 of the roller group 36 are respectively installed at the bottom of the two sliding seats 373. When in use, the return spring 374 will push the two connecting seats 371 to move toward each other along the sliding rod 372, so that the roller group 36 can be retracted, ensuring that the two cleaning rollers 361 can fit tightly on the inner and outer surfaces of the dustproof grid 32 to ensure the cleaning effect.

[0034] The utility model provides a dustproof structure for air-cooled refrigeration equipment, in which a self-cleaning dustproof device 3 is arranged outside a fan unit 2, and a door opener 33 is used to first control a dustproof grid 32 to flip outward and open, so that a pair of rollers 36 and the dustproof grid 32 are in the same direction, and then a linear module 34 controls the pair of rollers 36 to move back and forth along its track, and when the pair of rollers 36 passes the position of the dustproof grid 32, two cleaning rollers 361 of the pair of rollers 36 are respectively fitted on the inner and outer surfaces of the dustproof grid 32 to move, so as to clean the dustproof grid 32. The dust adhered to the surface of the grid 32 can be swept away, and both the inner and outer surfaces of the dustproof grid 32 can be cleaned to further improve its cleaning effect. A clamping mechanism 37 is set on the top of the roller group 36, and the two cleaning rollers 361 of the roller group 36 are respectively installed at the bottom of the two slide seats 373. When in use, the return spring 374 will push the two connecting seats 371 to move toward each other along the slide rod 372, so that the roller group 36 is folded, ensuring that the two cleaning rollers 361 can fit tightly on the inner and outer surfaces of the dustproof grid 32 to ensure the cleaning effect.
