DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an air conditioner.

[0002]

2. Description of the Related Art In recent years, several measures for heat insulation have been devised in order to prevent heat transfer in the structure of an air conditioner.

Conventionally, an air conditioner has been disclosed in Japanese Utility Model Publication No. 63-2834.
No. 3 is disclosed. Hereinafter, the conventional air conditioner will be described with reference to the drawings.

FIG. 7 is a cross-sectional view of a conventional air conditioner. In FIG. 7, reference numeral 1 denotes a heat exchanger. 2 is a blower. 3 is a drain pan. 4 is a heat insulating material. 5 is drain water. 6 is a wind direction board. 7 is a filter. 8 is a cabinet. 9 is an outlet. Reference numeral 10 denotes a water absorbing member.

The operation of the air conditioner configured as described above will be described below.

First, the air drawn by the blower 2 passes through the filter 7, is heat-exchanged by the heat exchanger 1, and is discharged from the outlet 9. At this time, the drain water 5 condensed in the heat exchanger 1 accumulates in the drain pan 3.

[0007]

However, the above-mentioned conventional construction has a heat insulating material 4 for preventing heat transfer from the cooled heat exchanger 1 and the drain water 5 to the cabinet 8, and a water retention for perspiration caused by insufficient heat insulation. Although the water absorbing member 10 was used in order to do so,
The water-absorbing member 10 has a disadvantage that it has a limited water-holding power and is not preferable in appearance.

The present invention solves the conventional problems,
The purpose is to reduce the amount of heat insulating material and eliminate water absorption members.

Further, in the above-mentioned conventional configuration, when a heat insulating material is arranged in a portion having irregularities, the heat exchanger 1 and the drain water 5 are not cooled because the heat insulating material cannot obtain a sufficient heat insulating effect due to its complicated shape.
There is a disadvantage that it is difficult to prevent heat transfer from the cabinet to the cabinet 8.

Another object of the present invention is to prevent the transfer of heat from the cooled heat exchanger and drain water to the cabinet even in the uneven portion of the cabinet.

In addition, the above-mentioned conventional configuration has a drawback that it is difficult to prevent heat transfer to the cabinet 8 when the heat insulating material 4 is disposed in a space-constrained structure.

An object of the present invention is to prevent heat transfer from a cooled heat exchanger and drain water to a cabinet in a limited space.

Further, the above-mentioned conventional configuration has a disadvantage that if moisture or dust adheres between the heat insulating material 4 and the cabinet 8, it is not preferable for hygiene.

Another object of the present invention is to prevent the occurrence of mold even when moisture or dust adheres to the cabinet.

In addition, the above-described conventional configuration has a disadvantage that the number of steps in manufacturing and assembling is increased because the heat insulating material 4 and the cabinet 8 must be fixed.

Another object of the present invention is to reduce the number of steps in manufacturing and assembling.

[0017]

In order to achieve this object, the present invention uses an air conditioner using a heat diffusion member.

As a result, it is possible to reduce the number of heat insulating materials and eliminate the water absorbing member.

Further, the present invention uses a heat diffusion member and a substance whose shape can be freely changed in an air conditioner.

Thus, even in a portion having unevenness of the cabinet, heat transfer from the cooled heat exchanger and drain water to the cabinet can be prevented.

Further, the present invention has an air conditioner having a heat diffusion member provided with irregularities.

Thus, even when the space is limited due to the structure, it is possible to prevent the heat transfer from the cooled heat exchanger and the drain water to the cabinet.

Further, the present invention has a heat diffusion member obtained by subjecting an air conditioner to a fungicide treatment.

Thus, even when moisture or dust adheres to the cabinet, the generation of mold can be prevented.

Further, in the present invention, a heat diffusion member is integrally formed with an air conditioner.

As a result, the number of steps in manufacturing and assembling can be reduced.
