Description

[Detailed Description of the Invention] The present invention relates to an improved structure of the outer shell of an air conditioner.

As shown in FIG. 3, in a conventional air conditioner, ventilation louvers 12 are formed by cutting and bending on both sides of the outer shell 11 located on the outdoor side. Since the louver 12 is opened flush with the wall, if it is installed on a thick wall, a part of the louver 12 will be located within the wall A, and that part will be blocked. This has the disadvantage that the ventilation area is substantially reduced, and the required amount of ventilation cannot be obtained, which adversely affects the cooling capacity itself.

The present invention eliminates the above-mentioned drawbacks of the conventional type, and the present invention will be explained with reference to an embodiment shown in the figure below. 1 is a main body base of an air conditioner, 2 is an outer shell provided on the outside thereof; An indoor heat exchanger 3 is placed on one side of the base 1, an outdoor heat exchanger 4 is placed on the other side, and a Shirotsko fan on the indoor side is placed between the two.
A fan motor 5 equipped with a propeller fan, a compressor 6, etc. are arranged on the outdoor side. Further, a partition plate 7 is provided to divide the indoor heat exchanger 3 and the Shirotsuko fan into an indoor side and an outdoor side, and the compressor 6 and the fan motor 5 are mounted on both side plates of the outer shell 2 located outside the partition plate 7. , a ventilation port 8 for circulating outside air to the outdoor heat exchanger 4 is formed, but the ventilation port 8 is
is a concave stepped portion 9 that is one step inward from the plate surface of the side plate.
The opening is made by punching or the like.

With the above configuration, the recessed step part 9 is formed in the outer shell 2, and the ventilation port 8 is opened in this, so that when installed on a thick wall part A as shown in FIG. Even if a part of the ventilation hole 8 is located within the same wall surface part A, a gap is formed between the recessed step part 9 and the plate surface of the outer body 2 due to the step, so the ventilation to the outside air is prevented from being blocked. Since the ventilation area is secured, there is no need to reduce the ventilation area and not be able to obtain the required amount of ventilation, which adversely affects the cooling capacity itself, unlike in the conventional type.

Note that by forming the recessed step 9, it will be close to the internal parts of the compressor 6, etc., but the ventilation hole is not formed by cutting and raising as in the conventional type, but by punching. Since it is formed in a single layer, it does not come into contact with internal parts.

Fig. 1 is a perspective view of the main parts of an air conditioner showing an embodiment of the present invention, Fig. 2 is a cutaway plan view of the main parts, and Fig. 3 is a cutaway plan view of the main parts of a conventional air conditioner. . In the figure, 1 is the main body base, 2 is the outer shell, 3 is the indoor heat exchanger, 4 is the outdoor heat exchanger, 6 is the compressor,
7 is a partition plate, 8 is a ventilation hole, and 9 is a recessed step.
