JPH0367949A - Air outlet grille for air conditioner - Google Patents

Abstract

PURPOSE:To prevent dew formation for a long period cooling operation, and achieve a uniform finish and a reduction in the production cost by producing an air outlet grille in such method that a strength core of low-expansion ratio plastic is covered with an external part of high expansion ratio plastic to form an external frame, and the external frame is adequately cut and assembled into the air outlet grille. CONSTITUTION:An air outlet grille main body 6 is continuously molded of hard foamed plastic and consists of external parts 7 and strength cores 8. The strength cores 8 are made of low expansion plastic and the external parts 7 are made of high expansion plastic. That is, the strength core 8 and the external part 7 each having different expansion ratios compose an external frame 12. The strength core 8 and the external part 7 are extruded simultaneously to form the outer frame 12, and louvers 9 to be used as air deflectors are provided inside the air outlet grille main body 6 composed of the outer frames 12. This constitution prevents dew formation on the air outlet grille main body 6 as it is heat-insulated from the surroundings and allows producing the air outlet grilled 6 at a low cost.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an outlet grill used for an outlet of an air conditioner or a duct type air conditioning system.

BACKGROUND ART Conventionally, in ceiling-embedded air conditioners, wall-embedded air conditioners, etc., an outlet grill is attached to the terminal of a duct installed in the ceiling, or to a wall surface. As shown in FIG. 3, this outlet grill has an outer frame 2 of an outlet grille 1 made of a steel plate, and is flocked with flocking material 3. The outer frame 2 is bent and finished by welding, etc., then painted, and flocked material 3 is flocked in the areas that come in contact with the blown air, and the outer frame 2 is surrounded by insulation made of soft foamed resin or the like. The outer periphery is covered with material 4, and during cooling, the outer frame 2 is covered with flocked material 3 and heat insulating material 4 to prevent dew condensation during cooling.

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

Problems to be Solved by the Invention In such a conventional configuration, processing costs increase because it is necessary to attach the heat insulating material 4 and construct the flocked material 3. In addition to requiring additional material costs, pasting the insulation layer 4 causes variations in work and the flocking material 3 does not have a uniform finish, reducing the commercial value of the outlet grill 1.9 It is also a long-term measure to prevent condensation. There were problems such as condensation occurring during hours of cooling operation.

3... The present invention solves these problems, and provides an inexpensive blow-out grill that does not cause dew condensation even during long-time operation during cooling, has a uniform finish, and is inexpensive. The purpose is to

Means for Solving the Problems In order to solve this problem, the present invention continuously molds the outer frame of the blow-out grille with a hard foamed resin, molds the outer part of the outer frame with a high expansion ratio resin, and forms a core. The outer frame consists of a strength core molded from a low expansion ratio resin, and the outer frame and the strength core are simultaneously extruded.

Due to the structure, the strength is maintained by the strength core molded with a low expansion ratio resin, and the outer shell is formed with a high expansion ratio resin that covers the strength core, and the strength core and the outer shell are formed to cover the strength core. The outer frame is cut to a size appropriate for the air outlet, and the air outlet is formed by adhesives or screws to each other, and the outer frame is insulated from the surrounding area to prevent condensation. At the same time, it can be provided at a low cost by being constructed from an extruded product.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. The main body 6 of the blowout grill is continuously molded from hard foamed resin, and is composed of an outer shell 7 and a strength core 8.
The strength core 8 is made of a low expansion ratio resin, and the outer shell 7
is made of a resin with 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 constructed by simultaneously molding the strength core 8 and the outer shell 7 as an extrusion molded product. Furthermore, a louver 9 serving as a wind direction changing device is provided inside the outlet grille 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 part 7 made of a high expansion ratio resin are foamed at different ratios, and the outer frame 12 is formed by simultaneous extrusion molding. This outer frame 12
are cut and cut to match the size of the outlet grille 6 as shown in FIG. That is, the four outer frames 7a, 7b, 70.
The outer frames 7a and yb are cut short to form the outer frame 7d, and the outer frame c and 7d are cut long to form the outer frame 7d, and the joints 10 at the four corners are joined with an adhesive or the like to form the outlet grille 6. be. Therefore, the size of the outlet grille 6 can be freely manufactured in accordance with the air volume of the air conditioning system. In this example, a rectangular outlet grill is used.
This can be freely configured, and can be configured into any shape such as a rectangular shape or a polygonal shape.

Effects of the Invention As is clear from the description of the above embodiments, the present invention provides a structure in which a strong core with a low foaming ratio is covered with an outer shell portion that covers the strength core with a high foaming ratio, and this structure is made up of the strong core and the outer shell. Since the outer frame is appropriately cut to form the outlet grille, the outer frame itself due to its high foaming ratio acts as a heat insulator, preventing condensation during cooling, and the size of the outlet grille can be adjusted to match the air volume of the air conditioning system. It can be manufactured freely to suit the needs of customers, and there is no need for pasting the heat insulating material, which was required in the past, and there is no loss of marketability due to unbalanced pasting. In addition, since the outer frame consisting of the outer shell part with a strength core is made into a single extrusion molded product, and this molded product is cut and bonded with adhesive, etc., costs are significantly reduced. It is something that you have.
