Problems solved by technology

The cross-flow fan of the air conditioner is one of the most difficult parts of the air conditioner to disassemble. To disassemble the fan must remove all the parts used, which will bring great trouble to cleaning the dust on the cross-flow fan
Cross-flow fans also don't clean up through frost like evaporator self-cleaning
The accumulated dust will be thrown directly from the fan and spread into the air in the room through the air duct, affecting the air quality

Abstract

The invention discloses an air conditioner indoor unit, a control method and a control device, and belongs to the field of air conditioners. The air conditioner indoor unit comprises a cover shell, across flow fan is arranged in the cover shell, and the air conditioner indoor unit further comprises a sweeping brush which is arranged on one side of the cross flow fan in the length extension direction of the cross flow fan, and a first driving mechanism which is used for driving the sweeping brush to rotate from the first direction to the second direction to enable bristles of the sweeping brush to be in contact with fan blades of the cross flow fan in the second direction. According to the air conditioner indoor unit, the control method and the control device, the first driving mechanism is controlled to drive the sweeping brush to rotate to the second direction to enable the sweeping brush to be in contact with the fan blades of the cross flow fan, so that when the cross flow fan rotates, the fan blades are sequentially swept from the bristles of the sweeping brush, then dust falls off and is collected by a dust collecting structure, so that self-cleaning of the cross flow fan andcollection and treatment of the dust are achieved; and the first driving mechanism is controlled to drive the sweeping brush to rotate to the first direction, the cross flow fan and other componentsare prevented from being touched, the occupation of the internal space of the air conditioner indoor unit is reduced, and the space waste is avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner indoor unit, a control method and a control device. Background technique [0002] The circulating air of the air conditioner first passes through the dust filter at the air inlet of the air conditioner for cleaning. The dust passing through the filter will adhere to the evaporator, and then the dust passing through the evaporator will fall on the cross-flow fan. The cross-flow fan of the air conditioner is one of the most difficult parts to disassemble. To disassemble the fan must remove all the parts used, which will bring great trouble to cleaning the dust on the cross-flow fan. Cross-flow fans also do not clean through frost the way evaporators self-clean. The accumulated dust will be thrown directly from the fan and spread into the air in the room through the air duct, affecting the air quality. If the cross-flow fan cannot be cleaned in time, th...
