2. Description of the Related Art Conventionally, for cleaning indoor units, an overhole or a simpler indoor unit which has been installed on a wall is covered with a waterproof cover, and a heat exchanger or a heat exchange room is used. The thing which performs washing of water was already known.

[0003]

In the above technology, dust easily adheres to the interior of an indoor unit such as an air conditioner, and furthermore, the plate fins of the heat exchanger are structurally adhering to water droplets and cause mold. In addition, mold breeding not only causes off-flavors,
During operation of the indoor unit, mold spores may be scattered from the air outlet, which may be unsanitary and harmful to humans.
And asthma attacks. In addition, in smoking in a room where an indoor unit is installed, tobacco odor is adsorbed to dust and mold in the indoor unit, and emits an odor due to cigarette odor together with dust and mold from the outlet.

As described above, dust and mold, and the tobacco odor adsorbed on the dust and mold, adhere to the wall surface in the heat exchange chamber, the blower fan, the louver and the dew tray at the outlet, in addition to the heat exchanger. ,
In particular, the blower fan has significant mold contamination. The antifungal agent is applied to the heat exchange room and the blower fan. The antifungal agent is very low for 2 years after the start of use. An increasing trend is generally recognized.

[0005] Under such circumstances, in the indoor unit,
Since the front panel was detachably mounted, partial cleaning of the front of the heat exchanger, which was removed and exposed to the outside, could be performed at home. However, the overall cleaning of the heat exchange chamber, blower fan, dew tray, louver, etc., which is separated by the back surface of the heat exchanger and the casing, requires removal of the blower fan, dew tray, and louver. At present, it is troublesome and not performed much.

[0006] The overall cleaning described above is usually performed by a trader. A typical method is an overhole, in which the indoor unit is removed from the wall in order to carry out the operation smoothly. After that, each part of the indoor unit is disassembled, and after cleaning, the parts are assembled again and attached to the wall, so that it takes a great deal of trouble, and it is difficult for an amateur other than the trader to work on the overhole. . In addition, since a fee for the cleaning operation is paid for the above-mentioned operation, it is uneconomical for the cleaning requester, and in reality, the cleaning request is not made much.

[0007] In addition, as a simpler cleaning method than the above-mentioned over-hole, an indoor unit is covered with a waterproof cover while being installed on a wall, and a heat exchanger or an elongated rod shape for spraying water into the heat exchange chamber. Cleaning using tools was performed. However, in such cleaning, the inside of the indoor unit is not sufficiently cleaned, and in particular, it is impossible to remove an object to be cleaned stuck on the surface of the blower fan. The present invention has been made to solve the above-mentioned drawbacks.

Collides with the motor shaft detachable mounting portions 19 and 19a. Then, it is necessary to slightly incline the blower fan 6 in order to prevent the collision. That is, one end shaft 15b
Is inserted into the through-hole 57 obliquely from the lower right while tilting slightly, but since the through-hole bearing body 58 is formed of the elastic body and has elasticity, the oblique lower end is tilted while the one end shaft 15b is tilted. It is possible to insert into the through hole 57, and at this time, the vicinity of the through hole 57 is deformed by the force from the one end shaft 15b. Here, as shown in FIG. 15A, the right end of the through-hole 57 is preferably formed in a conical groove 57c (the right opening 57a of the through-hole 57 corresponds to the circumference of the conical bottom surface of the groove 57c). ). If the inner diameter of the right opening 57a is substantially the same as the diameter of the one end shaft 15b,
Is difficult to insert into the right opening 57a of the through hole 57. However, if the inner diameter is enlarged like the circumference of the conical bottom surface of the conical groove 57c which is larger than the diameter, it becomes easy to insert the one end shaft 15b obliquely. When the one end shaft 15b is further inserted deeply, it reaches the apex portion of the conical shape, and a through hole 57b having substantially the same diameter as the diameter is provided from the apex portion.

One end shaft 15b can be withdrawn from through holes 57, 57b. Also, as described above, as a means for inserting or removing the through-hole bearings 58 from the diagonally lower right while slightly tilting the one-end shaft 15b without significantly deforming the through-hole bearing members 58, the mounting of the through-hole bearing members 58 is performed. By pivoting the piece 58c slightly firmly so as to be rotatable with respect to the vertical plane of the wall surface 5a of the housing 2, the axial direction of the through holes 57 and 57b can be rotated 360 degrees with respect to the vertical plane. Therefore, it is possible to insert or pull out the through-hole 57 from the obliquely lower right while tilting the one end shaft 15b, so that the through-hole bearing body 58 and the through-holes 57 and 57b do not require much deformation.
