Air conditioner filter screen self-cleaning device

Abstract

The invention discloses a self-cleaning device for an air conditioner filter screen, which is arranged on filter screen brackets at an air passage spiral casing air inlet of a cabinet air conditioner and is arranged outside the filter screen, an upper bracket and a lower bracket are provided with filter screen guide rails with slots, the filter screen is fixed on the filter screen brackets through the slots of the guide rails, a filter screen cleaning device comprises a cleaning component with a brush, a drive motor fixed on the cleaning component, a driving mechanism connected with the drive motor, a rack set arranged at the left side part and the right side part of the filter screen and a dust box arranged under the filter screen and used for collecting dust; a dust exchange device is arranged between the dust box and the filter screen; the drive motor connected with the driving mechanism drives the cleaning component to slide up and down along the rack set adhering to the filter screen in order to enable the brush to clean dust down; the cleaning component slides down to pass through the dust exchange device and cleans the dust down in the dust exchange device, and then the dust exchange device pours the dust to the dust box. The self-cleaning device for air conditioner filter screen saves time and labor and can be cleaned at any time without disassembling.

Description

technical field [0001] The invention relates to a self-cleaning device for an air conditioner filter screen, in particular to a cleaning device capable of automatically cleaning the 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...

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
