Indoor unit for air-conditioning apparatus

Abstract

An indoor unit 100 of an air-conditioning apparatus includes vanes 4, vane shafts 4a and 4b, which are disposed at the ends of the vanes 4, vane bearings 11 and 12, which hold the vane shafts 4a and 4b, and motors 9, each of which is mounted on a corresponding one of the vane shafts 4a and each of which causes a corresponding one of the vanes 4 to rotate. Each of the vane shafts 4b is provided with a rib 4c, and each of the vane bearings 12, which hold the corresponding vane shafts 4b, is provided with a hook portion 12c. When one of the vane shafts 4b moves by a reference movement amount in a direction toward the corresponding vane shaft 4a, the corresponding rib 4c and the corresponding hook portion 12c engage with each other, so that movement of the vane shaft 4b is restricted.

Description

technical field [0001] The present invention relates to an indoor unit of an air conditioner. Background technique [0002] Conventionally, there is a bathroom heating device that includes: a frame member having a bearing portion and an air outlet formed therein; an air outlet unit having a motor storage box connected to the frame member; and a wind direction adjustment louver. , which has rotation shafts on the left and right sides, and is rotatably supported by the frame member; and a stepping motor for driving the blind, which is stored in a motor storage box (for example, refer to Patent Document 1). In the bathroom heating device described in Patent Document 1, the rotation shaft of the wind direction adjustment louver is connected to the drive shaft of the stepping motor. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2003-14286 (page 3, Figure 5 ) [0004] However, in the bathroom heating equipment described in Patent Document 1, there is a ...

Problems solved by technology

[0004] However, in the bathroom heating equipment described in Patent Document 1, there is a problem that the rotation shaft of the blade receiving the rotational force from the stepping motor (motor) of the air direction adjustment shutter (blade) breaks before the other rotation shaft of the blade. In some cases, the rotating shaft of the other side of the blade cannot support the self-weight of the blade in the direction of falling, so it falls into the indoor space.
