Embodiments of the present invention will be described below in detail with reference to the drawings. 1A to 1C and FIG. 2A
2 (B), reference numeral 1 denotes an indoor unit main body of the air conditioner, 1a denotes a synthetic resin base constituting the main body 1, 2
Are suction ports provided on the front and upper parts of the main body 1;
Is a substantially rectangular heat exchanger provided in an air passage connecting the suction port 2 and an air outlet described later. The heat exchanger 3 has a vertical portion 3a having a dew receiving portion a at a lower portion and an upper end thereof. It consists of a rear inclined portion 3b bent rearward, and the tip of the rear inclined portion 3b is supported by the base 1a, but is supported by a support member to be described later when it is exchanged for a smaller one by, for example, a minor change. The configuration is such that:

4 is a blower fan provided in the air passage, 5 is a blower outlet for blowing out the suction air heat-exchanged by the heat exchanger 3 by the blower fan 4 toward the room,
6 is a group of left and right wind direction plates rotatably supported by the outlet 5;
7 is a vertically rotatable plate rotatably supported similarly, 8 and
8 ′, when the heat exchanger 3 including the vertical portion 3a and the rear inclined portion 3b is replaced with a smaller one, for example, by a minor change, and is provided in the air passage, a lower end of the rear inclined portion 3b is provided. A support member to support,
By forming the supporting members 8 and 8 'along the longitudinal direction of the tip of the rear inclined portion 3b, the lower end of the rear inclined portion 3b is accurately supported, and the tip of the rear inclined portion 3b and the Fill the gap between the base 1a
The configuration is such that the suction air sucked from the suction port 2 can be prevented from being sent to the outlet 5 without passing through the heat exchanger, so that the heat exchange efficiency is not reduced.

As shown in FIGS. 1A and 1B as the first embodiment, the support member 8 has a receiving portion 8a for receiving the lower end of the rear inclined portion 3b. A locking claw 8b is provided above and below the receiving portion 8a to form a substantially U-shaped cross section, and a locking hole 1b corresponding to the locking claw 8b is provided in the base 1a, and the locking hole 1b is provided in the locking hole 1b. The locking claw 8a is locked so that the tip of the rear inclined portion 3b is received and supported by the receiving portion 8a, whereby the rear inclined portion received by the receiving portion 8a is formed. The lower end of the front end of the rear inclined portion 3b can be accurately supported by the support member 8 in which the locking claw 8a is locked in the locking hole 1b. 1a, so that the heat exchange efficiency of the heat exchanger 3 can be prevented from lowering. It is a structure that can be used.

As shown in FIG. 1C as a second embodiment, the supporting member 8 has a receiving portion 8a for receiving a lower end portion of the rear inclined portion 3b and has a substantially U-shaped cross section. On the other hand, the base 1a is provided with a substantially concave locking portion 1c having an open front, corresponding to both ends of the supporting member 8, and the both ends of the supporting member 8 are engaged with the locking portion 1c. By stopping and supporting the front end of the rear inclined portion 3b with the receiving portion 8a, the suction air flows from the locking portion 1c described in the first embodiment to the rear side of the main body 1. The structure is such that the heat exchange efficiency of the heat exchanger 3 can be prevented more effectively so as not to decrease.

As shown in FIGS. 2A and 2B as a third embodiment, the supporting member 8 'is provided between the lower end of the rear inclined portion 3b and the base 1a. Interposed,
By attaching to the base 1a, the lower end of the rear inclined portion 3b can be more easily supported,
Since the gap between the tip of the rear inclined portion 3b and the base 1a can be filled by the support member 8 ', a structure is provided in which the heat exchange efficiency of the heat exchanger 3 can be prevented from being reduced. .

The support member 8 'is made of an elastic material such as urethane foam. As shown by the dimensional relationship "b <c" in FIG. It is formed with a dimension slightly larger than the gap between the lower part and the base 1a, so that its elasticity is utilized to make it possible to closely support the lower end of the rear inclined portion 3b and accurately support it. Becomes

The support members 8 and 8 'are made of a heat-insulating member such as urethane foam, for example, so that the temperature before and after the heat exchange by the heat exchanger 3 is performed. The configuration is such that both intake airs having a difference can be insulated.

Further, since the base 1a is provided with the protruding holding piece 1d for holding the lower portion of the support member 8 ', the attached support member 8' does not displace from the base 1a. As shown in FIG.

Further, since the holding piece 1d is formed integrally with the base 1a, the dimensions and shape can be finished with high accuracy, and the structure is advantageous in terms of cost.

With the above configuration, FIGS.
(C) and, as shown in FIGS. 2 (A) and 2 (B), a substantially vertical portion 3a having a dew receiving portion a at a lower portion and a rear inclined portion 3b having its upper end bent rearward. When the heat exchanger 3 is replaced with a smaller one by a minor change or the like and provided in the air passage in the main body 1, the heat exchanger 3 can be easily and accurately attached and supported, and the suction The air conditioner prevents the suction air sucked from the port 2 from passing through the air passage in a state where the heat exchange is not performed in the heat exchanger 3 so that the heat exchange efficiency is not reduced. .

[0025]

As described above, according to the present invention, a substantially rectangular heat exchanger consisting of a vertical portion and a rear inclined portion having its upper end bent backward is replaced with a smaller heat exchanger. The air conditioner can be easily supported so that no gap is generated in the air conditioner.
