た。(b) Prior art A heat exchange unit incorporated in a small wall-mounted air conditioner has a main body casing of the unit and a fan casing housed within the casing to approximately the full width thereof, both of which are made of the same material made of synthetic resin. There is. However, in recent years, there has been a demand for increased heat exchange capacity for wall-mounted air conditioners, and when a heat exchange unit with a larger width is manufactured based on this demand, the main body casing of this unit is made of synthetic resin, similar to conventional small units. Since integral molding would result in high mold costs and insufficient strength, attempts have been made to form the main body casing from a sheet metal material. However, in such a structure, the fan casing, which is made of synthetic resin, has a higher coefficient of thermal expansion than the main casing, which is made of sheet metal. As a result, both side plates of the main body casing bulged outward, and there was a risk that the bearings of the side plates and the rotating shaft of the crossflow fan would be misaligned, and the crossflow fan would not rotate smoothly.

In Figures 1 and 2, a sheet metal material 1 is bent into a substantially U-shape to integrally form a top plate 2, a back plate 3, and a bottom plate 4, and side plates 5a and 5b made of sheet metal are separate members. The main body casing of the heat exchange unit is spot-welded to the top plate 2 and the bottom plate 4, 6 is a glass wool insulation material attached to the inner wall of this casing, 7 has scroll parts 8a and 8b on the left and right, and has a higher thermal expansion than sheet metal. A fan casing is integrally formed with a foamed urethane material having a high ratio. 9 is an electric motor for driving the cross flow fans 10a and 10b facing inside the scroll parts 8a and 8b, respectively. 11 is a motor for driving the cross flow fans 10a and 1.
This is a plate fin type heat exchanger located on the windward side of 0b.

ある。 Reference numerals 12a and 12b are through holes formed in the side plates 5a and 5b for inserting the cross flow fans 10a and 10b, and projecting rings 13a and 13b integrally projected inward by burring are arranged around the holes. 14
A and 14b are bearing portions for the cross flow fans 10a and 10b that close the through holes 12a and 12b from the outside.

The fitting holes 16 are fitted into the protruding rings 13a, 13b, respectively, and the elastic heat insulating materials 15a, 15b are positioned and bonded to the inner walls of the side plates 5a, 5b. Thereafter, the fan casing 7 is housed from the front to approximately the full width in the main casing 1, and both end surfaces of the fan casing 7 are covered with elastic heat insulating material 15.
a, 15b, and incorporates the heat exchanger 11 and cross flow fans 10a, 10b, and supports the fans rotatably by bearings 14a, 14b. By attaching a suction grill (not shown) to the open front part of the main body casing 1 and decorative panels 17a and 17b on both sides, a wall-mounted air conditioner is completed, and the indoor air is heated from the suction grill. Exchanger 11, cross flow fans 10a, 10b
The heat exchanger 11 acts as an evaporator or a condenser, thereby cooling or heating the room.

板5a,5bの変形防止、延いては軸受部14
a,14bの位置ずれが防止される。 During such heating, since the fan casing 7 has a larger coefficient of thermal expansion than the main casing 1, this difference in elongation force is applied in the width direction, causing the fan casing 7 to bite into the elastic heat insulating materials 15a and 15b. That is, the stretch of the fan casing 7 is absorbed by the elastic heat insulating materials 15a and 15b, preventing deformation of the side plates 5a and 5b, and further preventing the bearing portion 14.
Misalignment of a and 14b is prevented.

こともない。 When the heating operation is switched to a simple ventilation operation and the fan casing 7 approaches its original length as the temperature decreases, the elastic heat insulating material 1
5a and 15b are also restored to their original states, and no air leaks from between the fan casing 7 and both side plates 5a and 5b.

防止できる。 In addition, during cooling, the fan casing 7 shrinks more than the main casing 1 due to cooling, so in consideration of this, elastic insulating materials 15a, 1 are used.
5b is made somewhat thicker so that it is already inserted between the end surface of the fan casing 7 and the side plates 5a and 5b at room temperature, the fan casing 7
It is possible to prevent cold air from leaking between the and both side plates 5a and 5b.
