Abstract

The invention provides an indoor unit for an air conditioner, capable of preventing a movable panel from descending in the cleaning process of a filter to normally clean the filter. The indoor unit has a housing with a suction inlet, the movable panel for opening and closing the suction inlet, a panel moving mechanism, the filter, a brush and a brush driving device. The panel moving mechanism hasan elevating motor for generating a driving force to drive the movable panel to move and drive the movable panel to reciprocate between the preset opening position and the preset closing position. The filter is arranged in the housing to filter the air introduced from the suction inlet. The brush is mounted on the movable panel in a rotatable way to clean the filter. The brush driving device is disposed in the housing to drive the brush to rotate. The brush driving device acts to excite the elevating motor of the panel moving mechanism, so that the elevating motor can not run, thus the movable panel can not move, or the elevating motor generates the power for applying the force to close the movable panel.

Description

technical field [0001] The present invention relates to an indoor unit of an air conditioner, particularly an indoor unit provided with a movable panel. Background technique [0002] Among ceiling-mounted indoor units, various indoor units having a function of periodically cleaning an air filter provided in an air intake path with a brush have been proposed. [0003] Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2007-40689) describes an indoor unit in which an air filter cleaning brush is attached to a movable panel that can be raised and lowered. In the indoor unit, dust or dust scraped from the air filter by the brush is collected in a dust box on the moving panel. Dust or dirt stored in the dust box is lowered together with the mobile panel together with the dust box, and is taken out from the dust box by an operator to the outside and discarded. [0004] However, during cleaning of the filter, when the brush is driven, a force may act on the...
