Description

Air conditioner outdoor unit automatic dust removal device

technical field

The utility model relates to an automatic dedusting device, in particular to a device for automatically dedusting a heat exchanger of an outdoor unit of an air conditioner.

Background technique

The fins of the heat exchanger of the existing air conditioner outdoor unit are narrow, and the fin slits of the heat exchanger are easily blocked by dust and catkins. Well, it affects the cooling efficiency of the air conditioner. In high temperature weather, it will frequently cause overheating protection of the compressor and damage the compressor. At present, the heat exchanger fins of the outdoor unit of the air conditioner are cleaned by manual washing, which has the problems of difficult washing, heavy maintenance workload and high labor cost. The existing utility model patents "dust-proof net for outdoor unit of air conditioner" (patent No. 98221749.8) and "dust-proof device for outdoor unit of air conditioner" (patent No. 201020527805.9) are dust-proof by adding dust-proof devices , can only play a role in dust prevention, but not dust removal.

Contents of the invention

The utility model provides an automatic dust removal device for an outdoor unit of an air conditioner, which solves the problem that the existing air conditioner dustproof device can only prevent dust but not remove dust.

The utility model solves the above technical problems through the following technical solutions:

An automatic dust removal device for an air conditioner outdoor unit, comprising an air conditioner outdoor unit casing, a dustproof net is arranged outside the air conditioner outdoor unit casing, a right fixing bracket is fixedly arranged on the right front side of the air conditioner outdoor unit casing, and on the right fixing bracket There is a right guide rail rod in the vertical direction, a rear fixing bracket is fixed on the left rear side of the air conditioner outdoor unit casing, a motor is fixed on the rear fixing bracket, and a lead screw in the vertical direction is connected to the output shaft of the motor , a sleeve is arranged at one end of the L-shaped moving brush rod, and a screw nut is arranged at the other end of the L-shaped moving brush rod. An L-shaped hairbrush is fixedly arranged on the inner surface of the shaped movable brush bar. The motor is a miniature motor that can be rotated forward and reverse.

The utility model adopts a high-efficiency dust-proof net, which can effectively block large particles of dust or catkins outside the dust-proof net. The motor drives the L-shaped moving brush rod, and through uninterrupted automatic reciprocating dust removal, it can obviously slow down the dirty speed of the heat exchanger. , greatly reducing the cleaning times of the heat exchanger and maintaining the heat exchange performance of the air conditioner. At the same time, the dust removal device for the outdoor unit of the air conditioner of the utility model has the advantages of simple manufacturing process and convenient maintenance.

Detailed ways

An automatic dust removal device for an air conditioner outdoor unit, comprising an air conditioner outdoor unit casing 1, a dustproof net 2 is arranged outside the air conditioner outdoor unit casing 1, and a right fixing bracket 3 is fixedly arranged on the right front side of the air conditioner outdoor unit casing 1, On the right fixed support 3, the right guide rail bar 4 of the up and down vertical direction is arranged, and the left rear side of the air conditioner outdoor unit casing 1 is fixedly provided with the rear fixed support 5, and the rear fixed support 5 is fixedly provided with the motor 11, the motor 11 The output shaft of the motor is connected with a lead screw 6 in the vertical direction, a sleeve 8 is arranged at one end of the L-shaped moving brush rod 7, and a screw nut 9 is arranged at the other end of the L-shaped moving brush rod, and the sleeve 8 is movably socketed. On the right guide rail bar 4 , a screw nut 9 is screwed on the screw mandrel 6 , and an L-shaped hairbrush 10 is fixedly arranged on the inner surface of the L-shaped movable brush bar 7 . The motor 11 is a reversible miniature motor.

When the automatic dedusting device is energized, the motor 11 directly drives the screw rod 6 to rotate, and the rotating screw rod 6 drives the screw nut 9 to move up and down. There is a through hole 12 on the ring of the screw nut 9, and the L-shaped moving brush rod 7 passes through the The hole 12 acts as an axial fixation, so that the L-shaped moving brush rod 7 moves up and down at a constant speed, so as to achieve the purpose of the L-shaped brush 10 moving up and down to clean the dust-proof net 2.
