Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger cleaning, in particular to a device for cleaning a heat exchanger of an outdoor unit of an air conditioner. Background Art

[0002] With the advancement of science and technology, people's quality of life is constantly improving. Air-conditioning equipment has entered every household and has become one of the indispensable household appliances in users' lives. After the air-conditioning outdoor unit has been used for a period of time, some dust and dirt will accumulate on the heat exchanger. Excessive accumulation of dust and dirt on the heat exchanger will affect the working efficiency of the air conditioner and reduce the cooling and heating performance of the air conditioner. Therefore, the heat exchanger of the air conditioner needs to be cleaned regularly.

[0003] The existing patent (publication number: CN217342532U) discloses an external cleaning device for an air-conditioning heat exchanger, comprising a heat exchanger body located inside the air-conditioning shell, the top and bottom of the heat exchanger body are fixedly connected to a fixing plate by bolts, screw rods are vertically arranged on both sides of the front end between the two fixing plates, both ends of the screw rod are rotatably connected to the fixing plate, the two screw rods are connected by a linkage assembly, guide sliding rods are vertically arranged on both sides of the rear end between the two fixing plates, both ends of the guide sliding rods are fixedly connected to the fixing plate, and a movable plate is arranged between the screw rod and the guide sliding rod on the same side. The utility model can clean both sides of the heat exchanger at the same time, with high cleaning efficiency. While cleaning, the heat exchanger can be brushed with a cleaning brush to improve the cleaning effect, and there is no need to disassemble the shell of the air-conditioning, so cleaning is convenient.

[0004] The above patented technology drives the moving plate to move by rotating the screw rod so that the cleaning brush can brush the heat exchanger.

Therefore, a heat exchanger cleaning device for an air conditioner outdoor unit is proposed. Utility Model Content
