Filter screen assembly for air conditioner outdoor unit, air conditioner and control method

Abstract

The invention provides a filter screen assembly for an air conditioner outdoor unit, an air conditioner and a control method, the air conditioner outdoor unit comprises a shell and an outdoor fan, and an air inlet and an air outlet are formed in the first side wall and the third side wall of the shell correspondingly; the filter screen assembly comprises a supporting structure, a filter screen and a driving mechanism; the supporting structure comprises a plurality of supporting columns which are arranged in the shell and are sequentially arranged at intervals; the driving mechanism drives the filter screen to annularly move between the air inlet and the air outlet, so that the outdoor fan cleans dust on the filter screen; the structure is simple, the coverage area of the filter screen is large, the condenser can be protected in real time, the dedusting effect and the filtering effect are guaranteed, the dedusting process is simplified, and the dedusting efficiency is high; the invention further provides a control method of the air conditioner. The control method comprises the steps that the accumulative operation duration and the preset duration of the air conditioner outdoor unit are compared, the filth blockage degree of the filter screen is judged, the driving mechanism is controlled to drive the filter screen to move, and the outdoor fan is controlled to clean dust on the filter screen; the automation degree is high and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a filter assembly used for an outdoor unit of an air conditioner, an air conditioner, and a control method. Background technique [0002] In the outdoor unit of the air conditioner, the air entering the outdoor unit is filtered by setting a filter at the air inlet of the outdoor unit, so as to avoid the reduction of the heat transfer amount and the deterioration of the heat transfer effect when the condenser is seriously blocked, but the filter has a long service life. Finally, it needs to be cleaned; someone proposes to set a filter track in the shell of the outdoor unit, and when the filter slides to the air inlet along the filter track, it can filter the dust in the air; when the filter slides to the air outlet along the filter track, At the same time, the air from the outdoor fan can blow the dust on the filter screen; but the structure of the dust removal device in ...
