DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. 1 to 3 show an embodiment of an air conditioning box according to the present invention. FIG. 1 is an overall perspective view of an air conditioning box 10.
The material 0 has a sound absorbing property and / or a heat insulating property, and is formed by compression molding into a solid rectangular box shape. Although glass wool is used in the examples, the material is not limited to this, and other materials may be used, or an ordinary glass fiber surface may be covered with an aluminum foil or the like.

The air conditioning box 10 has an inlet 12 and an outlet 14 formed on at least two side surfaces P and Q. Either the inlet or the outlet may be the inlet or the outlet, but a flexible duct or the like is connected to the side for feeding air to serve as the inlet, and the side connected to the outlet is the outlet. The inlet 12 and the outlet 14 are communicated with each other in the box body to form a substantially arc-shaped wind flow passage 16.

In this embodiment, as shown in FIG. 1, the air-conditioning box 10 is compression-molded with first and second half-cut molding portions 18 and 20 having a split joint surface S that vertically cuts the air flow passage 16. Then, the divided joint surfaces S are adhesively bonded to each other to form an integral box body.

What is characteristic of the present invention is that
The box was assembled by joining six glass wool boards corresponding to each surface, and the flow path was formed by molding to configure the box, and the so-called stealing was performed on a desired portion inside the box other than the wind flow path 16. That is, the void portion 22 serving as a portion is provided.

As a molding method, for example, a material such as glass wool is press-compressed and pressed into a mold to be formed. Since glass wool is press-compressed and molded, not only long-fiber ones but also short-fiber ones can be used because they do not scatter due to air flow. If necessary, neoprene or other surface treatment may be performed. Further, other synthetic resin, vinylidene chloride in a molten state, chloroprene rubber or the like may be sprayed on the surface to form the layer. Compared with the conventional case of forming six glass wools by staking them by forming an air-conditioning box made of high-density crowwool by molding, it suffices to perform only the work of joining at the split joint surface S. The assembly work time is quick and the assembly accuracy is high. Therefore, work efficiency is significantly improved.

Further, in particular, the first and second half-cut molding portions 1
By forming 8 and 20, the flow path of the wind can be configured to have an arbitrary curvature, shape, etc. Especially when air flows into the air conditioning box from the conventional duct, the flow path suddenly expands in this box. However, since the pressure loss is large, which causes unfavorable results in the rectification and noise reduction design, the resistance loss is reduced due to the required smooth arc shape as if the duct was placed inside the box. It is possible to make an air-conditioning box configuration with less noise.

Further, by forming the void portion 22 in the box portion other than the flow passage of the wind at the time of molding, the entire box can be made extremely lightweight, and it becomes easy to operate at the time of assembly, handling, transportation and the like. Therefore, the material cost can be kept low. Further, for example, when the guide vanes are formed in the flow passage of the wind, when the air conditioning box is molded, it can be integrally molded by forming irregularities in the molding die in advance.

In the embodiment, the first and second half-cut molding portions 18 and 20 having the division joint surface S are compression-molded in advance, and these are adhesively bonded to form an integral box body. Instead of using the cracking mold, it may be integrally formed from the beginning by using a disappearing mold such as a foamed polystyrene material. The molding is not limited to the two-division, but may be divided into three or other division dies.

FIG. 3 shows another embodiment of the air-conditioning box. In this embodiment, a plurality of holes 24 are opened in the wall 16a forming the flow passage 16 of the wind so as to communicate with the void portion 22. There is. As a result, at the same time as the stealing portion that saves weight and saves material costs, the resonance effect of sound due to the pores and cavities is generated, and the sound of the air-conditioning box and the near edge is effective especially in the sound near the resonance frequency. To mute. Figure 4
As shown in FIG. 5, in the embodiment, holes 24 are formed in the inside and outside of the bend of the flow passage wall 16a so as to communicate with the corresponding voids 22.
