Abstract

Official abstract text for this publication.

An indoor unit of an air-conditioning apparatus includes: a heat exchanger which generates conditioned air by carrying out heat exchange between refrigerant and indoor air; and a drain pan disposed below a lower end of the heat exchanger to correct dew condensation water. The drain pan includes at a side portion thereof: a side dew receiving portion which receives dew condensation water; and a recessed portion disposed below the side dew receiving portion, the recessed portion being recessed toward an other side portion opposite to the side portion. A side face of the drain pan is provided with a heat insulating sheet covering an entire opening of the recessed portion.

First claim

Opening claim text (preview).

The invention claimed is: 1. An indoor unit of an air-conditioning apparatus comprising: a heat exchanger configured to generate conditioned air by carrying out heat exchange between refrigerant and indoor air; and a drain pan disposed below a lower end of the heat exchanger to correct dew condensation water, wherein the drain pan includes at a side portion thereof: a side dew receiving portion configured to receive dew condensation water; and a recessed portion disposed below the side dew receiving portion, the recessed portion being recessed toward an other side portion opposite to the side portion, and wherein a side face of the drain pan is provided with a heat insulating sheet covering an entire opening of the recessed portion. 2. The indoor unit of the air-conditioning apparatus of claim 1 , wherein the drain pan includes, at a central portion thereof, a central dew receiving portion configured to receive dew condensation water, the side dew receiving portion includes a connecting portion having an inner wall, the inner wall defining a drain port, and the recessed portion is recessed at least up to a position at the inner wall, the position being most proximal to the central dew receiving portion. 3. The indoor unit of the air-conditioning apparatus of claim 2 , wherein the recessed portion includes a surrounding wall which covers a lower face of the side dew receiving portion, with space provided between the surrounding wall and the lower face, and the surrounding wall includes a plurality of ribs protruding into the space. 4. The indoor unit of the air-conditioning apparatus of claim 1 , wherein the recessed portion includes a surrounding wall which covers a lower face of the side dew receiving portion, with space provided between the surrounding wall and the lower face, and the surrounding wall includes a plurality of ribs protruding into the space.
