Abstract

A housing cover provided on a housing section of an indoor unit of an air conditioning apparatus, the indoor unit including a casing, and the housing section provided on a bottom portion of the casing and having a remote control receiving section for receiving an infrared signal from a remote control and a temperature detection sensor for contactlessly detecting a surface temperature of an object in a room, the housing cover comprising a light transmissive surface inclined diagonally downward from a front and a sensor opening port formed behind the light transmissive surface, wherein the light transmissive surface is formed in front of the remote control receiving section to be opposed to and be parallel to the remote control receiving section, and the sensor opening port is formed such that the temperature detection sensor protrudes from the opening port.

First claim

The invention claimed is:

1. A housing cover that is provided on, and that substantially covers, a housing section of an indoor unit of an air conditioning apparatus, wherein the housing section:
is provided on a bottom portion of a casing, which is rectangular in shape when viewed from a side, of the indoor unit;
includes a remote control receiving section configured to receive an infrared signal from a remote control and a temperature detection sensor configured to contactlessly detect a surface temperature of an object in a room; and
protrudes downward from the bottom portion of the casing,
the housing cover comprising:
a light transmissive surface inclined diagonally downward from a front; and
a sensor opening port formed behind the light transmissive surface, wherein:
the light transmissive surface is formed in front of the remote control receiving section to be opposed to and be parallel to the remote control receiving section, and
the temperature detection sensor protrudes from the sensor opening port.

2. The housing cover of claim 1 , wherein
a flange, which has a shape tapering from the top to the bottom and has a bottom diameter that is smaller than a top diameter, is formed on a periphery of the sensor opening port.

3. The housing cover of claim 1 , wherein:
the housing section has a manual operation switch for manually causing the air-conditioning apparatus to operate,
the housing cover comprises a switch opening port formed behind the light transmissive surface; and
the manual operation switch faces downward from the switch opening port.

4. The housing cover of claim 3 provided with
an openable lid openably and closeably covering the manual operation switch.

5. An indoor unit of an air conditioning apparatus, the indoor unit comprising:
a casing having a rectangular shape in a side view;
a housing section provided on the bottom portion of the casing and including:
a remote control receiving section for receiving an infrared signal from a remote control, and
a temperature detection sensor configured to contactlessly detect a surface temperature of an object in a room; and

a housing cover provided on the housing section, protruding downward from the bottom portion of the casing, the housing cover comprising:
a light transmissive surface inclined diagonally downward from a front, and
a sensor opening port formed behind the light transmissive surface, wherein:
the light transmissive surface is formed in front of the remote control receiving section to be opposed to and be parallel to the remote control receiving section, and
the temperature detection sensor protrudes from the sensor opening port.

6. The indoor unit of the air conditioning apparatus of claim 5 , wherein:
the housing section has a manual operation switch for manually causing the air-conditioning apparatus to operate;
the housing cover comprises a switch opening port formed behind the light transmissive surface; and
the manual operation switch faces downward from the switch opening port.
