Conventionally, a decorative panel in a ceiling-embedded indoor unit has been manufactured by sheet metal processing or by mold molding of a synthetic resin.
However, in the former case, since the weight of the decorative panel becomes very large, there is a drawback that the installation property is deteriorated and the manufacturing cost is increased. In the latter case, the decorative panel can be reduced in weight, but since the strength is reduced, a gap may be formed between the lower surface of the ceiling due to bending.

Also, in this type of air conditioner, the width dimension in the left-right direction is changed according to the air conditioning capability (horsepower) while keeping the length in the front-rear direction constant. However, in the latter case, since a mold for the decorative panel is required for each width dimension, the cost is increased.

This invention is made in view of such a situation, and it aims at providing the indoor unit of the air conditioning apparatus which can aim at the weight reduction of a decorative panel, cost reduction, and strength improvement with sufficient balance. To do.

Further, in this type of indoor unit, an air outlet is formed in the vicinity of the outer periphery of the decorative panel, but the strength of the side portion of the decorative panel along the longitudinal direction of the air outlet is reduced due to the presence of the air outlet. It is easy to do, and the side part of the decorative panel orthogonal to the longitudinal direction of the blower outlet is not easily influenced by the blower outlet, and it is easy to ensure the strength. Therefore, in this invention, the strength reduction of a decorative panel can be suppressed by providing a side panel made of a synthetic resin on both sides of a center panel orthogonal to the longitudinal direction of the air outlet.

The said structure WHEREIN: It is preferable that the said decorative panel is formed in the rectangular shape, and the short side part of this decorative panel is comprised by the said side panel.
When the decorative panel is formed in a rectangular shape, the short side portion has higher strength than the long side portion and is difficult to bend. Therefore, the short side portion is constituted by a side panel made of synthetic resin. Strength reduction can be suppressed.

The side panel may be formed with an operation opening for operating a fixture for attaching the main body case in the ceiling from below the ceiling.
With such a configuration, the opening for operation can be easily formed in the side panel by molding.

It is preferable that a metal reinforcing member is attached to the side panel along its longitudinal direction.
With such a configuration, the strength of the side panel can be increased, and a gap between the ceiling and the ceiling due to bending can be prevented.

It is preferable that the side panel is provided with a connecting portion connected to the main body case, and the reinforcing member is disposed in the vicinity of the connecting portion.
With such a configuration, the connection strength of the side panel to the main body case can be effectively increased.

In this embodiment, the decorative panel 32 includes a center panel 71 and a side panel 72, the center panel 71 is made of sheet metal, and the side panel 72 is made of synthetic resin. Therefore, it is possible to reduce the weight and cost of the decorative panel 32 as compared to the case where the entirety is made of sheet metal. Further, the strength can be improved as compared with the case where the entire decorative panel 32 is made of synthetic resin. In particular, since the front and rear side portions of the decorative panel 32 are located on the long side of the rectangular shape, the front and rear side portions are more easily bent than the left and right side portions located on the short side. Since it is comprised by 71, bending can be made as small as possible and it can prevent that a clearance gap produces between the ceilings 30. FIG.

Moreover, since the blower outlet 46 and the suction inlet 45 are formed in the vicinity along the front-and-back side part of the decorative panel 32, there exists a tendency for the intensity | strength of the said front-and-rear side part of the decorative panel 32 to fall. Since the side portion is constituted by the center panel 71 made of sheet metal, the strength reduction can be suppressed.
On the other hand, the left and right side portions of the decorative panel 32 are located on the short side of the rectangle and are arranged orthogonal to the longitudinal direction of the air outlet 46 and the air inlet 45, so that the air outlet 46 and the air inlet 45 are arranged. There is little influence of the strength reduction due to, and it is relatively easy to secure the strength. Therefore, even if the left and right side portions of the decorative panel 32 are configured by the side panels 72 made of synthetic resin, the strength reduction can be suppressed.

Further, since the side panel 72 is provided with the reinforcing member 80 along the front-rear direction, the side panel 72 can be prevented from being bent, and a gap is prevented from being generated between the side panel 72 and the ceiling 30. Can do. The reinforcing member 80 is provided between the front and rear connecting

portions

76 and 77 with respect to the main body case 31. Between the front and rear connecting

portions

76 and 77, the side panel 72 is the portion that is most easily bent. Therefore, this portion can be effectively reinforced by the reinforcing member 80, and bending can be prevented. Furthermore, since the front end and the rear end of the reinforcing member 80 are disposed in the vicinity of the front and rear connecting

portions

76 and 77, the connection strength between the main body case 31 and the side panel 72 can be increased.

In the ceiling-embedded indoor unit 11 as in the present embodiment, the width dimension in the left-right direction is changed according to the air conditioning capability (horsepower) while keeping the length in the front-rear direction constant. If the entire decorative panel 32 is made of synthetic resin, a mold must be prepared for each model having different width dimensions in the left-right direction, which increases manufacturing costs. In this respect, in the present embodiment, the center panel 71 located at the center in the left-right direction of the decorative panel 32 is made of sheet metal, and the side panel 72 located on the side in the left-right direction is made of synthetic resin. If the width dimension of 71 in the left-right direction is changed according to the air conditioning capability, the side panel 72 can be used among a plurality of models. Since the center panel 71 is made of sheet metal, it is possible to eliminate the need for a molding die, and even if the width dimension is different, the center panel 71 can be handled at a lower cost than the molding of synthetic resin.

Since the center panel 71 of the decorative panel 32 is made of sheet metal as described above, when the air cooled from the air outlet 46 shown in FIG. 5 is blown out, the periphery of the air outlet 46 is cooled and condensation is likely to occur. Become. For this reason, a synthetic resin frame member 46a having a thermal conductivity lower than that of the metal is provided at the front end edge of the air outlet 46 to prevent the occurrence of condensation.

On the other hand, since the frame member 46a is made of a synthetic resin, the coefficient of linear expansion is large, and the frame member 46a is easily expanded and contracted due to a change in ambient temperature. When the frame member 46a expands, the frame member 46a may bend when it contacts the side panel 72. To prevent this collision, a gap is provided between the side panel 72 and the frame member 46a. , Looks worse.
Therefore, in the present embodiment, as shown in FIG. 10, a recess 73g is formed in the upper panel 73 of the side panel 72, and when the frame member 46a expands, its end is accommodated in the recess 73g. Even if the frame member 46a contracts, the length of the frame member 46a is set so that there is almost no gap between the frame member 46a and the side panel 72. Since the recess 73g is covered by the lower panel 74, it is not exposed to the outside. Therefore, the frame member 46a does not abut against the side panel 72 and bends, and the appearance is not impaired by the gap between the side panel 72 and the frame member 46a.

The present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the invention described in the claims.
For example, in the said embodiment, although the one blower outlet 46 was formed in the front part side of the decorative panel 32, the blower outlet 46 may be formed also in the rear part side. That is, the indoor unit of the present invention may be of a type in which air is blown out from two places before and after the decorative panel 32.
In addition, the decorative panel 32 is formed with a room air inlet 45, but air may be taken into the main body case 31 through a duct or the like from an inlet formed in a place other than the decorative panel 32. Good.
