Indoor unit of air conditioner

摘要

An objective of the invention is to obtain a structure which allows a cleaning mechanism, such as dust removal means, for an air filter to be easily mounted in an indoor unit of an air conditioner that has an air filter on the intake side of an indoor fan. The indoor unit is constituted by a main unit (10) including an indoor heat exchanger (22) and an indoor fan (21) for blowing air taken from a room to the indoor heat exchanger (22), a cleaning unit (100) located on the room side of the main unit (10) and including an air filter (30) and dust removal means (50) for removing dust captured by the air filter (30), and an indoor panel (11) for covering the room side of the cleaning unit (100).

主权项

1. An indoor unit of an air conditioner, the indoor unit having in a casing an indoor heat exchanger, an indoor fan for blowing air taken from a room to the indoor heat exchanger, and an air filter located on an intake side of the indoor fan, the indoor unit comprising:
a main unit including the indoor heat exchanger and the indoor fan; a cleaning unit located on a room side of the main unit and having the air filter and a dust removal unit for removing dust captured by the air filter; a first electrical component box, positioned in the main unit, housing electrical components for controlling a motor of the indoor fan, the first electrical component box being structurally separate from an indoor fan motor housing; a second electrical component box, positioned in the cleaning unit, housing electrical components for controlling a motor of the dust removal unit, the second electrical component box being structurally separate from a dust removal unit motor housing; and an indoor panel for covering a room side of the cleaning unit, wherein the main unit includes a casing which is open toward a room, the cleaning unit includes a casing located on an opening side of the casing of the main unit and stacked on the casing of the main unit, the indoor panel is stacked on the casing of the cleaning unit to cover an opening of the casing of the cleaning unit that opens in a downward direction towards a room side, one or more air outlets being formed on the indoor panel, and the first and second electrical component boxes are electrically connected to each other via at least one signal line such that signals can be transmitted between the components housed in the first electrical component box and the components housed in the second electrical component box.
