Abstract

The invention discloses an air conditioner indoor unit capable of preventing the pollution on a heat exchanger caused by the dust attached to the heat exchanger. The air conditioner indoor unit comprises a housing having an air inlet in an upper part; a fan used for sucking the indoor air in the housing via the air inlet; a filter capable of collecting the dust in the indoor air sucked in the housing; a heat exchanger, which is disposed on a downstream side of the air flow further than the filter, and can be used for the heat exchange with the indoor air; a filter cleaning mechanism, which is provided with a brush and a dust collecting case. The brush is provided with a plurality of brush hairs in a planted manner from a base part vertically, and when the brush is contacted with the filter, the filter can move to remove the dust of the filter, and then the dust can be collected in the dust collecting box. The dust collecting box is provided with a blocking wall, which is disposed close to the contact parts of the brush hairs of the brush, and is extended upwards from the part of the upstream side of the air flow.

Description

technical field [0001] The invention relates to an air conditioner indoor unit with a filter cleaning mechanism. Background technique [0002] Conventionally, there have been air-conditioning indoor units in which a filter for collecting dust is disposed upstream of a heat exchanger in air flow so that dust in sucked indoor air does not flow to the heat exchanger. Moreover, the air-conditioning indoor unit of recent years has the air-conditioning indoor unit provided with the filter cleaning mechanism which removes the dust collected by a filter from a filter. For example, in the indoor unit of the air conditioner disclosed in Patent Document 1 (Japanese Unexamined Patent Publication No. 6-114224), brushes are arranged in contact with the filter, and the filter is moved in a state where the filter is in contact with the brush. to remove dust.
