DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an air conditioner. More particularly, the present invention relates to a structure of an indoor unit for facilitating a cleaning operation of a blower fan.

[0002]

2. Description of the Related Art FIGS. 10 and 11 show a conventional general indoor unit of a separate type air conditioner for home use. In FIGS. 10 and 11, 1 is a main body, 2 is a top cover, and 3 is a front cover. Reference numeral 4 denotes an outlet. Each of the upper cover 2 and the front cover 3 is provided with a suction port 5 and is detachably attached to the main body 1.

Further, an air passage 8 formed by a fan casing 6 and a stabilizer 7 is formed in the main body 1, and a blow fan 9 composed of a cross flow fan and a heat exchanger 10 are provided in the air passage 8. Is rotatably arranged by a motor 11 and a bearing 12, and a water tray 13 for receiving drain water is arranged below the heat exchanger 10.

A large number of left and right blades 15 for adjusting the left and right wind directions are provided at the outlet 4 so as to be rotatably supported by the fan casing 6, and are provided in front of the upper and lower blades for adjusting the up and down wind directions. The blades 16 are rotatably supported on both side wall surfaces 4 a of the outlet 4, and an air filter 14 is provided on the rear surface side of the front cover 3.

[0005] The air conditioner having the above configuration is configured such that air blown from the inlet 5 by the blower fan 9 provided in the air passage 8 exchanges heat with the heat exchanger 10 and is blown from the outlet 4. Has become. At this time, the large dust in the air is removed by the air filter 14, but the fine dust adheres to the fin surface 10a of the heat exchanger 10 and the surface of the blower blade 9a of the blower fan 9, and although it depends on the frequency of use, the use 2 ~ 3
