Description

Air conditioning filter automatic cleaning device

technical field

The utility model belongs to the field of automatic cleaning of machines and relates to the automatic cleaning of air conditioner filter nets.

Background technique

At present, most of the filter screens at the air inlet of the indoor unit of the air conditioner need to be manually cleaned to achieve the purpose of cleaning.

Detailed ways

Below in conjunction with the embodiment shown in the accompanying drawings the utility model is further described.

An automatic cleaning device for an air conditioner filter, the structure of which is shown in the accompanying drawings, including a filter mechanism, a driving support mechanism, and a cleaning and dust suction mechanism.

The filter mechanism is cylindrical, which mainly includes a filter 1 and a filter frame 2. The filter is mainly placed on the side of the cylinder. Place them in the guide grooves of the guide rail 3 on the filter screen and the guide rail 4 under the filter screen respectively.

The driving support mechanism includes structures such as a driving motor 9, a motor support frame 8, a support column 11, a gear 10, a dust collection chamber 5, a guide rail 3 on the filter screen and a guide rail 4 under the filter screen. The motor support frame 8, the lower track 4 of the filter screen and the dust collection chamber 5 are respectively fixed on the air duct volute, and the track 3 on the filter screen is supported and fixed by the motor support frame 8 and the dust collection chamber 5. Motor 9 is fixed on the motor support frame 8, and gear 10 is fixed on the motor shaft, and under the drive of motor 9, gear 10 drives filter net frame 2 and moves circularly along the upper and lower tracks. In addition, four support columns 11 are connected to support the upper and lower filter screen guide rails, while limiting the filter screen from breaking away from the guide rails during motion.

The cleaning and dust suction mechanism is made up of parts such as hairbrush 13, suction nozzle 12, dust collection cavity 5, dust suction port 17, dust suction pipe 14, dust suction fan 15, dust discharge pipe 16.

Wherein, hairbrush 13 is fixed on the base 7 of dust collection chamber 5, and suction nozzle 12 is located in the middle of hairbrush 13, and dust collection chamber 5 also plays a supporting role to guide rail 3 on filter net while collecting dust. Driven by the gears, the filter frame moves in a circular motion, and the brush contacts with it to remove the dust on it; at the same time, using the negative pressure provided by the dust suction fan 15, the swept dust is sucked into the dust collection chamber 5 through the suction nozzle 12, and passed through After the dust suction port 17 and the dust suction pipe 14 are discharged to the dust suction fan 15, they are discharged outdoors through the dust discharge pipe 16.

The above-mentioned hairbrush 13 is made of long and short bristles, and the bristles on the upper half are shorter than the bristles on the lower half, so that during the cleaning process, the filter screen rotates clockwise, and the bristles on the upper half contact the filter screen first, and the dust dropped by the brush falls on the bristles on the lower half , to avoid the dust flying everywhere, so that there is a layer of dust inside the indoor air conditioner.

The suction nozzle 12 is designed as a slit structure, which is beneficial to the absorption of dust.

The dust collecting chamber 5 is composed of a dust collecting chamber base 7 and a dust collecting chamber top cover 6 . The base 7 of the dust collection chamber is used to fix the suction nozzle 12 and the brush 13; the top cover 6 of the dust collection chamber plays a sealing role.
