Embodiment Construction

[0029] The indoor unit of the air conditioner of this embodiment is such as Figure 1~3 shown. The indoor unit includes a heat exchanger 1 and a fan 2 built in a casing 3 . A suction port 4 is formed from the upper surface to the front surface of the casing 3 long in the left-right direction. An air outlet 5 is formed on a curved surface extending from the lower front surface of the housing 3 to the bottom surface. In addition, when the housing 3 is viewed from the front, the width direction is defined as the left-right direction, the depth direction is defined as the front-rear direction, and the height direction is defined as the up-down direction.

[0030] Inside the casing 3 is formed a blowing air path 6 from the suction port 4 to the blowing port 5 , and a heat exchanger 1 and a fan 2 are provided on the blowing air path 6 . The heat exchanger 1 surrounds the front and the top of the fan 2 . A detachable filter 7 is provided in the casing 3 facing the suction port 4 ...

Abstract

A locking section (31) for holding an end portion of a filter (7) that is mounted with the face side thereof being inserted toward a front surface is provided on a cabinet (3). A receiving rib (25) that configures a high / low portion (43) is provided at a lower end portion of the face side of the filter (7), and an end portion of the back side of the filter (7) is formed smoothly. When the filter (7) is inserted with the face / back of the filter (7) in the correct orientation, the lower end of the filter (7) is inserted without touching the locking section (31), the receiving rib (25) contacts the locking section (31), and the filter (7) is held. When the filter (7) is inserted with the face / back of the filter (7) in the incorrect orientation, a low portion (44) of the high / low portion (43) of the filter (7) contacts the locking section (31), and insertion of the filter (7) is impeded. Accordingly, incorrect insertion of the filter (7) is capable of being prevented by making it impossible to mount the filter (7) when the filter (7) is inserted with the face / back of the filter (7) in the incorrect orientation.

Description

technical field [0001] The present invention relates to an air conditioner in which a filter is disposed on a suction port of a casing. Background technique [0002] In the indoor unit of the air conditioner, a fan and a heat exchanger are built in a casing. A suction port is formed from the top surface of the casing to the front surface, and the front cover is provided so as to cover the suction port on the front surface, and can be opened and closed and detached. The filter is disposed on the casing in a detachable manner facing the suction port, and the filter is disposed along the front cover on the rear side of the front cover. [0003] When the front cover is open, the filter can be attached and removed. In order to install the filter simply, Patent Document 1 discloses forming a plurality of ribs at the bottom of the filter, and forming a U-shaped holding part with an upper opening on the lower part of the front bracket where the suction port is formed. Hold the lo...
