Claims

[Scope of utility model registration request]

A casing attached to the wall of the room, a suction port provided at the top of the casing to allow indoor air to flow into the casing, and a suction port provided at the bottom of the casing to allow air inside the casing to flow into the room. a heat exchanger arranged at an inclination in the front-rear direction inside the housing to cool or heat the air flowing into the housing from the suction port; In an indoor unit of an air conditioner equipped with a rotatable impeller that sends air that has passed through a heat exchanger into the room from an outlet, a front part of a casing located in front of the heat exchanger and the heat exchanger are provided. The back surface of the casing located behind the impeller and the impeller are formed of a porous structure having a porous layer whose specific gravity is continuously varied in the layer thickness direction or in the surface direction of the layer. The surface of the porous structure having a lower specific gravity in the thickness direction is arranged on the inner side of the casing, and the surface of the casing with a larger specific gravity is arranged on the outer side. By providing a front outer wall and a rear outer wall on the outer surface of the rear surface, an air layer is formed between the front surface of the casing and the front outer wall, and between the rear surface of the casing and the rear outer wall. An indoor unit for an air conditioner, characterized in that a sound absorbing section is constituted by the porous structure described above.
