The outdoor unit is usually placed outside the building and is responsible for the compression cycle process of refrigeration or heating; the indoor units are installed in various rooms or areas inside the building and are connected to the outdoor unit through pipelines. The indoor units can supply cold air or hot air as needed and send the air into the room through a fan; the pipelines are used to transport cold and hot media and distribute cold and hot air. Since the length of the central air duct system is relatively long, and the humid and warm space is prone to bacterial growth, the bacteria generated are blown into the room through the air outlet. Over time, it will cause damage to the health of the people in the room. Content of the Utility Model

[0003] The purpose of the utility model is to provide an air purification module of a central air conditioner to solve the problem that due to the relatively long length of the central air duct system, the humid and warm space is prone to bacterial growth, and the bacteria generated are blown into the room through the air outlet, which will cause damage to the health of the people in the room over time as mentioned in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an air purification module of a central air conditioner, including a ventilation box. A limiting groove is recessed inward at the middle position of the side wall of the ventilation box. A filter box is arranged inside the ventilation box and above the limiting groove. A filter element is arranged inside the filter box. A filter cotton is arranged inside the filter element. The filter cotton is arranged in an S-shaped fold inside the filter element. A fixed grid is arranged inside the filter box and above the filter element. A wind guiding box is arranged at the lower end inside the ventilation box. A wind guiding grid is arranged at the lower end inside the wind guiding box.

[0005] Preferably, a support edge is arranged at the lower end inside the filter box. The lower end of the filter element abuts against the support edge. A clamping groove is arranged at the upper end inside the filter box corresponding to the fixed grid. One side of the filter box extends out of the ventilation box and is provided with a fixing plate. The fixing plate is fixedly connected to the ventilation box through bolts. The fixed grid is clamped to the filter box through the clamping groove. The fixed grid and the support edge clamp and fix the filter element.

[0006] Preferably, a limiting edge is provided at the outer edge of the lower end of the air guide box, the upper surface of the limiting edge abuts against the lower end of the ventilation box, a support rod is provided at the upper end inside the air guide box, the upper surface of the air guide grille is fixedly connected to the support rod, and the air guide box is fixedly connected to the ventilation box by bolts.

[0007] Preferably, folding rods are staggeredly arranged at the upper and lower ends inside the filter element, and the filter cotton is sequentially wound around the outside of the folding rods.

[0008] Preferably, a fixing edge is provided at the outer edge of the upper end of the ventilation box.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows: Since the length of the central air duct system is relatively long, and a humid and warm space is prone to bacterial growth, a filter box structure that can be quickly disassembled is arranged inside the ventilation box. The bacteria and impurities inside the ventilation box are filtered by the filter box, and the quickly disassembled filter box can be conveniently replaced, reducing the bacteria blown into the room through the air outlet and reducing the damage to the health of the people in the room.
