Abstract

PURPOSE:To enhance the illumination effect and to enable to diffuse straightened air by arranging a diffusion punching plate capable of diffusing clean air to the ceiling of an air showering chamber and having light transmission property and providing an illuminator thereon. CONSTITUTION:When a fan is driven, dusts of polluted air in an air shower chamber 7 is removed by a prefilter 1 and a main filter 2, the clean air is then fed into a ceiling case 5 through a diffusion punching plate 6 into the chamber 7, and is similarly circulated. In this case, a diffusion punching plate 6 is formed of a material which has preferably in opening rate 20-60% of light transmission property such as an acrylic plate or a vinyl chloride plate. In this manner, an illuminator 4 which illuminates the interior of the chamber 7 can be installed in the case 5. The air which is converted to turbulent flow by the illuminator 4 is straightened by the plate 6 and can be diffused into the chamber 7.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air shower device having a structure for blowing clean air from a ceiling surface.

In the conventional structure shown in FIG. 1, the illumination lamp 4 is exposed inside the air shower room 7, so the lighting efficiency in the wi is good, but
There were safety issues. The one shown in Figure 92 is air V.
A lighting lamp 4 is embedded in the side of the Yawa Seal 7, but this has the disadvantage that the illumination effect inside the wealth 7 is poor because the lighting lamp 4 is located at the back. The third diagram is the light between the ceilings.
′! Although the T4 was embedded, there were drawbacks such as the illumination light 4 disturbing the flow of clean air, and the cleanliness of the room being difficult to maintain.

In the conventional case, an opaque material was used as the diffusion punching plate 6.

The present invention was developed in view of the above points, and an object of the present invention is to improve the lighting effect in a room and to prevent turbulence in the airflow directly under the lighting equipment.

That is, in the present invention, the air diffusion punching board on the ceiling is a punching board having a translucency with an aperture ratio of 20 to 60%,
In addition, the lighting equipment is provided above the punching plate. By doing so, it is possible to eliminate pure air flow and to obtain an indoor lighting effect. If the aperture ratio is made smaller than 20%, the amount of V-yawer sent into the air shower chamber will be reduced to 60%.
If it is set higher than , the rectification effect will decrease.

An embodiment of the present invention will be explained with reference to FIG.

Reference numeral 1 denotes a pre-filter, which is provided at the air outlet 8 of the IV shower chamber 7.

Reference numeral 2 designates a main filter installed in the duct 9 at the 10th stage of the pre-filter.

The duct 9 connects the inlet 10 of the fan S and the air outlet 8.

3 is a fan that sucks in 9 Ct'' of clean air filtered by the main filter 2 and blows the air into the air shower room 7.

A punching board 6 made of a translucent material with an aperture ratio of 20 to 6096, such as an acrylic board or a vinyl chloride board, is used as an air intake port 11 by a fan 1slC in the shower w17.
It is pasted below.

The lighting fixture 4 is provided above the punching plate 6 so as to illuminate the inside of the V-shaped chamber 7.

Now, the contaminated air is filtered by pre-filter 1. The dust is removed by the main filter 2 and the air becomes clean, which is then transferred to the ceiling case 5 by the blower 3. Diffusion punching plate 6 Plate 6 is ceiling case 5
The clean air that has become turbulent due to the lighting lights 4, etc. inside the room is rectified and flows into the room 7 as a laminar flow, purifying the room 7, and at the same time,
It is possible to maintain the illuminance of 7 in * without impairing the brightness of the illumination light.

Furthermore, by selecting a milky-white translucent material such as polyethylene or styrene as the material for the diffusion punching plate 6, it can also serve as a light diffusion plate.

According to the present invention, since the diffusion punching plate is made of a translucent material as described above, the light rays of the illumination lamps are not obstructed, and the brightness of the room can be maintained. In addition, the aperture ratio of the diffusion punching plate was selected to be 20% to 6%%, and since it was placed closer to the room than the lighting equipment, it had the effect of eliminating turbulence in the airflow directly under the lighting equipment.
