Cabinet air-conditioner dust gauze self-cleaning device and operation method thereof

Abstract

The invention discloses a cabinet-type air-conditioning strainer mesh self-cleaning device and the working methods, wherein the device consists of a suction nozzle mechanism and a strainer mesh mechanism; the strainer mesh mechanism is fixed outside the scroll casing of the air passage and consists of a strainer mesh and a strainer mesh frame; the suction nozzle mechanism is attached to the side of the strainer mesh facing outward, and consists of main body arranged on the strainer mesh and a suction nozzle arranged on the main body, wherein the main body is driven by a drive mechanism to slide between the left and the right sides of the strainer mesh along the track, and the suction nozzle is driven by another drive mechanism to slide between the top and bottom sides of the strainer mesh along the main body; the suction nozzle is provided with a dust absorption port and a brush, and is connected with the vacuum cleaner arranged in the air-conditioning through a connecting passage; the brush adjacent to the dust absorption port cleans the strainer mesh first, and then the connecting passage of the vacuum cleaner produces negative pressure high speed air flow by way of the suction nozzle, and the air flow keeps sucking the dust at the dust absorption port. The invention is characterized by reliable operation, low costs, wide ranged of dust absorption and good effect of dust cleaning.

Description

technical field [0001] The invention relates to an air conditioner filter screen cleaning device, in particular to a self-cleaning device capable of automatically cleaning the air filter screen at the air inlet side of an air conditioner indoor unit. Background technique [0002] At present, the dust removal method of ordinary split floor air conditioners is mainly to use the air filter installed near the air inlet to absorb the dust in the air, but too much dust on the filter will bring many negative effects. For example, too much dust causes the blockage of the filter mesh, causing poor ventilation, reducing the circulating air volume through the heat exchanger, affecting the cooling and heating effect, greatly reducing the air conditioning capacity, and increasing operating costs. At the same time, part of the dust on the filter screen may enter the indoor air again with the circulating air flow, affecting the indoor air quality and inconsistent with the health function o...

AI Technical Summary

Problems solved by technology

The dust suction method of this structure is through the rotation of the filter screen, so that the dust suction port moves relatively on the filter screen to achieve the effect of dust collection. However, because the filter screen rotation requires a high-power drive motor, the noise is relatively large. In addition, the dust suction port is a Slender opening, the opening is relatively large, and the suction effect is poor, so the dust removal effect is not ideal, especially in the area far from the middle of the filter, the dust removal effect is even worse
