DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative panel for an air conditioner.

[0002]

2. Description of the Related Art Conventionally, a decorative panel 1 of this type of air conditioner.
Has a structure as shown in FIGS. 3 and 4, for example. That is, the blowing guide 3 of the urethane foam is fixed to the periphery 2 of the outlet of the decorative panel 1 with the adhesive 3a. In addition, the blowing guide 3 of the urethane foam is
The cross-sectional shape was constituted by the same extrusion molding.

[0003]

However, in such a conventional structure, the blowout guide 3 is not mechanically fixed, so that when the air conditioner is operated, a heat shock occurs due to the temperature of the blowout port and the adhesive 3a Had the drawback that the adhesive strength of the pulp was weakened and it came off or fell off.

[0004] As a result, the air conditioner is operated with the blow-out guide 3 peeled off, and the blow-out wind is disturbed to make air conditioning ineffective, noise is generated, or the surrounding portion 2 of the blow-out port is operated during cooling operation. This impairs the air-conditioning function such as dew condensation. In addition, since the adhesive 3a is used, the number of man-hours during assembly has increased.

[0005] A blowing guide 3 for urethane foam
Has a drawback in that a recess cannot be provided in a part of the material because it is formed by extrusion molding having the same cross-sectional shape, and therefore, a heat insulating portion using an air layer cannot be provided. As a result, the material and weight could not be reduced.

[0006]

In order to solve the above-mentioned problems, a means of the present invention is to lock the peripheral portion of the outlet and the blow guide of the hard foam, and to blow the blow guide of the hard foam with a holding member. It is fixed around the exit.

In addition, a recess is provided in a part of the blow guide of the rigid foam.

[0008]

The operation of this technical means is as follows.
That is, the peripheral portion of the outlet and the blow guide of the rigid foam are locked and fixed by the holding member, so that the blow guide is mechanically fixed, so that there is no peeling or falling off.

[0009] Further, by providing a recess in a part of the blowing guide of the hard foam, a heat insulating portion can be formed by an air layer, and as a result, the material and weight can be reduced.
In addition, even during the cooling operation of the air conditioner, since there is no dew condensation around the outlet, it is possible to prevent the floor surface from being contaminated by dripping of the dew condensation water.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
This will be described with reference to FIG. Here, the same components as those in the conventional example are denoted by the same reference numerals, and description thereof is omitted.

1 and 2, reference numeral 11 denotes a decorative panel fixed below the air conditioner and exposed on the surface of the ceiling. Reference numeral 12 denotes a peripheral portion of the outlet of the decorative panel 11, which is provided with a blow guide 13 of a hard foam formed by molding. B direction in the left-right direction and C in the front-rear direction of the blowing guide 13
The fixing in each direction is performed by providing a convex portion 12a in the peripheral portion 12 of the outlet, a concave portion 13a in the blowout guide 13, and forming the tips of the convex portion 12a and the concave portion 13a into wedge shapes 12b, 13b, respectively. The peripheral portion 12 of the outlet and the blowout guide 13 can be locked.
Further, in the vertical direction D, the blowout guide 13 is held by the flanges 14a of two holding members 14 provided on the left and right of the peripheral portion 12 of the outlet, and the holding member 14 and the outlet guide 13 are fixed by screws 15 to the outlet. It is fixed to the surrounding part 12.

In the above configuration, when the decorative panel 11 is attached below the air conditioner, the blowing guide 13
Since the front, rear, up and down directions are mechanically fixed to the peripheral portion 12 of the outlet of the decorative panel 11, there is no peeling or falling off. That is, the fixing in the B direction in the left-right direction is performed by
The fixing in the C direction in the front-rear direction is performed with the concave portion 13a, and the tip of the convex portion 12a and the tip of the concave portion 13a are each formed in a wedge shape 1
2b and 13b, the peripheral portion 12 and the blow-out guide 13 can be locked. Further, the fixing in the D direction in the vertical direction is performed by using two
The blowout guide 13 is held down by the flanges 14 a of the holding members 14, and the holding member 14 and the blowout guide 13 are fixed to the peripheral portion 12 by screws 15.

Therefore, the air conditioner is operated with the blow-out guide 13 peeled off, and the blow-out wind is not disturbed, so that the air-conditioning does not become effective or noise is generated. 12 does not impair the air-conditioning function such as dew condensation. Also, since no adhesive is used, the number of man-hours during assembly is reduced.

Next, in FIGS. 1 and 2, a recess 13c is provided in a part of the blow guide 13 for hard foam formed by molding, so that the peripheral portion 12 of the outlet and the blow guide 13 for hard foam are provided. A heat insulating portion with an air layer can be formed therebetween.

Therefore, the material and weight can be reduced, and no dew condensation occurs around the blowout portion even during the cooling operation of the air conditioner, so that it is possible to prevent the floor surface from being contaminated due to dripping of dew condensation water. Further, since the blow guide 13 is made of a hard foam formed by molding, the blow air has good dimensional accuracy and is not disturbed even when the blow air passes through the blow guide, thereby preventing generation of abnormal noise.

[0016]

According to the present invention, as is apparent from the above description,
Lock the peripheral part of the outlet and the blowing guide of hard foam,
In addition, since the blowout guide is mechanically fixed by being fixed by the presser, the blowout guide does not peel off or fall off. As a result, the air conditioner is operated with the blow-out guide peeled off, and the blow-out air is not disturbed and air-conditioning does not work or abnormal noise does not occur. It does not impair the air-conditioning function such as dew condensation. Also, since no adhesive is used, the number of man-hours during assembly is reduced.

Further, by providing a concave portion in a part of the blowing guide of the hard foam, a heat insulating portion can be formed by an air layer. As a result, the material and weight can be reduced.
In addition, even during the cooling operation of the air conditioner, since there is no dew condensation around the outlet, it is possible to prevent the floor surface from being contaminated by dripping of dew condensation water.
