[0002]

2. Description of the Related Art A conventional housing for an air conditioner has a structure in which a panel 21 is fixed to an angle member 20 as a skeleton member by fixing members such as bolts and nuts 22 as shown in FIG. The panel 21 has an outer surface of a heat insulating material 23 covered with a metal plate 24, and has a packing 25 made of, for example, a soft synthetic resin material at an edge.

In the longitudinal direction of the angle member 20, a packing 26 made of, for example, a soft synthetic resin material is adhered. The packing seals between the panel and the angle member to maintain the airtightness of the housing. To prevent air leakage and condensation during cooling.

However, if the panel is opened and closed or detached during maintenance of the air conditioner, the packing 26 is peeled off from the angle member 20 and the seal between the panel and the angle member is insufficient, so that the airtightness is reduced. There's a problem.

Further, if the panel 21 is distorted due to a change in temperature or aging of the housing, a gap is formed between the panel and the angle member 20, and the airtightness of the housing becomes insufficient. In order to prevent the formation of the gap, it is only necessary to reduce the interval between the fixtures such as the bolts and nuts 22 for fixing the panel to the angle material. It cannot be adopted because of the disadvantage that opening and closing and attaching and detaching are not easy.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
It will be described based on FIG. Reference numeral 1 denotes an air conditioner, as shown in FIG. 2, wherein a panel 3 is attached to an angle member 2a serving as a frame member for a shaft assembly to form a housing. The edges are configured to be in airtight contact with each other, and the panel and its mounting structure will be described below.

Each panel is shown in FIG. 2 and subsequent figures.
It is a sandwich type in which a heat insulating material 4 such as foamed polyurethane is sandwiched between two plates 5 and 5, and the plates 5 and 5 are metal plates,
Preferably, it is made of a galvalume steel plate which is rich in rust prevention and is obtained by spraying galvalume which can be sprayed at a low temperature onto a steel plate.

A frame member 6 is attached to the four surroundings between the plate members 5 and 5. The frame member 6 has bent portions 6a facing each other at left and right side edges. The cross section in which the opening 7a for fitting is formed between the curved portions has a rectangular shape.

The edges 5a, 5a of the plate members 5, 5 are bent so as to face each other to form an opening 7b between the edges 5a, 5a which coincides with the opening 7a of the frame material. And edges 5a, 5a are bent portions 6a, 6a of the frame material.
The plate members 5 and 5 thus constitute a sandwich type panel sandwiching the heat insulating material 4.

An edge 8 is fitted around the periphery of the panel. The edge 8 is made of a hard material, for example, a hard synthetic resin material, and the outer surface of the edge is made of a soft material, for example, a soft material. A hollow tubular (for example, semicircular tubular as shown) packing 9 made of a synthetic resin material is formed integrally with the edge member 8.

Here, the packing 9 is in contact with the angle member 2 as shown in FIG. 2, for example, as shown in FIG. One or two are provided.

The edge member 8 is a channel rod having left and right pieces 8a, 8a and a bottom piece 8b.
5, two leg pieces 10 and 10 are press-fitted into an opening 7b between the bent portions 5 and an opening 7a between the bent pieces of the frame material.

The leg pieces 10, 10 are provided with expanding forces in the outward direction, that is, in directions opposite to each other, by their own elasticity, and bulge outward in an arc shape. Has a width that can be inserted into the opening portions 7b and 7a, and the bulging portion that has been forcibly press-fitted is engaged with the opening portion 7a and is prevented from coming off. Edge material 8
Is composed of a straight member 8A and an L-shaped corner member 8B for a square portion, and the packing 9 and the leg piece 10 have the same configuration.

The edge member 8 is divided into left and right pieces 8a, 8a.
On both sides of the panel (therefore, the left and right half portions 8a, 8
a has some elasticity), and the leg pieces 10, 10 are press-fitted into the opening portions 7b, 7a of the plate material and the frame material and mounted on the edge of the panel.

The left and right halves of the edge material thus fitted are tightly fitted to the panel, and the leg pieces 10 and 10 are
Does not come off by engaging with the edge of the opening 7a. In some cases, the straight member 8A of the rim is slid from the side to the panel and mounted.

The panel 3 is an A-1 type in which one packing 9 is provided on the side surface of the edge material as shown in FIGS. 3 to 6, and an A-2 type in which two packings 9 are provided in parallel as shown in FIGS. ,
As shown in FIGS. 9 and 10, there is an A-3 type in which one is provided on one side edge material and two are provided on the other side edge material, and other types of edge materials are variously combined.

FIGS. 10 to 13 show an example of how the panels are assembled. The rim 8 and the packing 9 may be made of any material, but the rim is made of a hard synthetic resin, and the packing 9 is made of a soft synthetic resin.

The air-conditioner housing 1 is assembled by appropriately attaching the panel having such a configuration to an angle member 2a forming a frame structure of a housing of the air-conditioner as shown in FIGS. . In the figure, reference numeral 2b indicates a pillar for a door.

The air conditioner includes a refrigerator including a compressor, a condenser, a liquid receiver, etc., a heat exchanger as a cooling / heating device, a blower,
A filter, a gas-liquid separator, etc. are provided in the housing, and the inlet 1
The air sucked into the housing from a is cooled or heated and blown out from the outlet 1b.

[0023]

The air conditioner housing assembled as described above has a hollow packing of a panel abutting against an outer surface of an angle member or an edge of an adjacent panel orthogonal to the angle member, or an angle member. And the panel edge.

Since the packing 9 has a hollow tubular shape, the packing 9 has an elastic deformation property in cross section. Therefore, even if the panel is distorted due to a temperature change or an aging change, the packing 9 adheres to the angle or the edge of the panel. The gap between the panel and the angle or the edge of the adjacent panel is completely sealed, the housing is kept airtight, and air leakage from the housing and condensation during cooling can be prevented.

Further, since the packing 9 is formed integrally with the rim 8 and does not peel off from the rim, the packing is peeled by opening and closing and detaching of the panel as in the conventional case, and the sealing becomes insufficient. The problem that the airtightness of the housing is reduced is solved.

Furthermore, since the panel is formed by sandwiching a heat insulating material with a steel plate, there is an advantage that cooling and heat in the housing are prevented from escaping to the outside of the housing, and the cooling and heat in the housing are effectively used. .
