Abstract

The air conditioner (100) includes an indoor heat exchanger (15), an indoor fan (16), a fan cleaning unit (24) that cleans the indoor fan (16) with a brush (24b), and the fan cleaning unit (24) and A control unit (30) in contact with the indoor fan (16), the control unit (30) having a brush angle changing member (31b1) for changing the angle of the brush in contact with the indoor fan (16).

Description

technical field [0001] The present invention relates to air conditioners. Background technique [0002] As a technique for cleaning an indoor fan (fan) of an air conditioner, for example, Patent Document 1 describes a device including a "fan cleaning device for removing dust from a fan". Also, of Patent Document 1 figure 1 Describes a structure in which the fan cleaning device is installed near the air outlet of the indoor fan. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Patent No. 4046755 Contents of the invention [0006] The problem to be solved by the invention [0007] In the technique described in Patent Document 1, the fan cleaning portion comes into contact with the fan before the rotation of the fan starts. Therefore, when the fan starts to rotate, a load is applied to the fan cleaning unit, and the fan cleaning unit tends to deteriorate, and if the fan cleaning unit deteriorates, there is a problem that the f...
