Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blowout grill used for an outlet of an air conditioner or a duct type air conditioning system.

2. Description of the Related Art Conventionally, in a ceiling-embedded air conditioner, a wall-embedded air conditioner, and the like, a blowout grill is attached to a terminal of a duct provided inside the ceiling or a wall surface. As shown in FIG. 3, the blow-out grill has the outer frame 2 of the blow-out grill 1 made of a steel plate, and the flocked material 3 is flocked. The outer frame 2 is bent by welding or the like for finishing, and then painted, and the flocked material 3 is applied.
Is flocked to a portion in contact with blown air, and the outer periphery of the outer frame 2 is protected by a heat insulating material 4 made of soft foamed resin or the like, and the outer frame 2 is covered with the flocking material 3 and the heat insulating material 4 during cooling. This prevents dew condensation during cooling.

On the other hand, although not shown, it is common to use a resin molded product having a low thermal conductivity for the outer frame 2, but even in this case, in order to prevent dew condensation, the heat insulating material 4 and the flocking material 3 are used. It was used after flocking.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In such a conventional configuration, since the heat insulating material 4 must be attached and the flocked material 3 must be installed, the processing cost increases, and the heat insulating material 4 and the flocked material 3 In addition to the need for material cost, the work of sticking the heat insulating material 4 is not uniform, and the finish of the flocking material 3 is not uniform, and the product value of the blowout grill 1 is reduced. Had problems such as dew condensation.

The present invention solves such a problem, and an object of the present invention is to obtain a low-cost blowing grille that does not cause dew condensation even during long-time operation during cooling and that has a uniform finish. It is a thing.

Means for Solving the Problem In order to solve this problem, the present invention is to continuously mold the outer frame of the blowout grill with a hard foam resin, mold the outer frame of the outer frame with a high expansion ratio resin, and The part is composed of a strength core molded from a resin having a low expansion ratio, and the outer frame and the strength core are simultaneously extruded to form an outer frame.

Action With this configuration, the strength is maintained by the strength core formed of the low expansion ratio resin, and the outer shell is formed by the high expansion ratio resin that covers the strength core, and the outer frame formed by the strength core and the outer shell is formed. Are appropriately cut into pieces according to the size of the air outlet, and are insulated from each other with an adhesive or with the surroundings that make up the air outlet by a method such as screwing to prevent dew condensation and to be extruded. By configuring, it will be provided at a low cost.

Example An example of the present invention will be described below with reference to FIGS. 1 and 2. The body 6 of the blowout grill is continuously molded of hard foam resin, and is composed of an outer shell portion 7 and a strength core 8,
The strength core 8 is made of a resin having a low foaming ratio, and the outer shell 7
Is made of a resin having a high expansion ratio, and thus the outer shell 7 and the strength core 8 have different expansion ratios to form the outer frame 12. Further, the outer frame 12 is formed by extruding both the strength core 8 and the outer shell portion 7 at the same time. Further, a louver 9 serving as a wind direction changing device is provided inside the blowing grill 6 constituted by the outer frame 12.

In the above structure, the strength core 8 made of a low expansion ratio resin and the outer shell 7 made of a high expansion ratio resin are foamed at different ratios, and the outer frame 12 is first formed by coextrusion molding. The outer frame 12 is cut according to the size of the outlet grill 6 as shown in FIG. That is, the outer frames 7a, 7b are short to form the four outer frames 7a, 7b, 7c, 7d, and the outer frames 7c, 7d are cut so as to be long, and the joint portions 10 at the four corners are made of an adhesive or the like. Are joined together to form the outlet grill 6. Therefore, the size of the outlet grill 6 can be freely manufactured according to the air conditioning system. In this embodiment, the rectangular blowing grille is used, but this can be freely configured, such as a quadrangular shape or a polygonal shape.

EFFECTS OF THE INVENTION As will be clear from the description of the embodiments, the present invention forms a strength core with a low expansion ratio and an outer shell formed by coating the strength core with a high expansion ratio, and comprises a strength core and an outer shell. Since the outer frame is appropriately cut to form the blowout grill, the outer shell itself with a high foaming ratio already acts as a heat insulating material, prevents dew condensation during cooling, and controls the size of the blowout grill to that of the air conditioning system. It can be freely manufactured according to the air volume, the pasting work of the heat insulating material is no longer required as in the past, and there is no deterioration in the productability due to imbalanced sticking. In addition, since the outer frame composed of the outer shell having the strength core is formed by one extrusion molding, and this molded product is cut and adhered with an adhesive or the like, the cost can be remarkably reduced. is there.
