Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a step-type air shower device installed in a clean room in the fields of electronics, medicine, medicine, etc.

Conventionally, as this type of air shower device, the first
I got what is shown in the figure. In this figure, 1 is a blower, 2 is a high-performance filter, 3 is a blowing nozzle, 4 is a medium-performance filter, 5 is a start switch for the blower 1, and 6 is a box housing these. 7 and 8 are doors, 9 is a timer that determines the operating time of the blower 1, and 10 is a footboard through which the object to be removed passes.

Next, the operation will be explained.

Open the door 7, enter the box 6, and press the start switch 5 to activate the blower 1. Air is sucked in through the medium-performance filter 4, passes through the high-performance filter 2, and is emitted from the blow-off nozzle 3 as a strong wind. It grows and pops out. Dust is removed by exposure to this wind. After the timer 9 stops, the door 8 is opened and the user goes outside.

Conventional air shower devices are configured as described above, so in order to improve the dust removal effect on objects to be removed, that is, people and materials, it is necessary to apply air evenly over the entire surface. In order to do this, there was a need to rotate within the device and move the limbs significantly. However, it had the disadvantage that it was difficult to apply wind across the entire surface due to the height of the person and the size of the materials.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology.By attaching an air shower device to the staircase part of a building, it is possible to easily blow air across the entire surface regardless of the height of the person or the size of the material. The purpose of the present invention is to provide an air shower device that can be applied to Hereinafter, this invention will be explained with reference to the drawings.

FIG. 2 shows an embodiment of the present invention, where numerals 1 to 9 are the same as those shown in FIG.
0A indicates a stepped tread.

Next, the operation will be explained.

Open the door 7, enter the box 6, and press the start switch 5 to activate the blower 1. Air is sucked in through the medium-performance filter 4, passes through the high-performance filter 2, and is emitted by the blow-off nozzle 3 as a strong wind. However, in the air shower device with this configuration, since the footboard 10A is stepped, the dust object to be removed inside the box body 6 must be removed from the blow-off nozzle 3 when going up the step-like footboard 10A. Since the relative position is constantly changed, the wind can easily hit the entire surface of people and materials, and the dust removal effect can be improved.

In the above embodiment, the doors 7 and 8 are provided in the box body 6.
Although the door 8 is shown as having a door 8, an air curtain having substantially the same effect may be provided in place of the door 8, and the starting switch 5 may be a starting switch using light or ultrasonic waves. Furthermore, timer 9
Instead, a stop switch for the blower 1 may be provided near the outlet.

As explained above, according to the present invention, the tread of the air shovel device is installed in a stair-like manner, so that regardless of the height of the person or the size of the material, by going up or down the stairs, the blowing nozzle can be Because the relative positional relationship between the two changes, the wind can be applied almost completely to the entire surface. Furthermore, in the case of humans, going up and down stairs inevitably increases the movement of the body, especially the limbs, which is highly effective in removing adhering dust.

Furthermore, since the staircase portion of a building has traditionally been an area with low utilization efficiency, the use of this area has advantages such as being preferable from the standpoint of effective use of space.

[Brief explanation of the drawing]

FIG. 1 is a partially cutaway perspective view showing a conventional air shower device, and FIG. 2 is a partially cutaway perspective view showing an embodiment of the present invention. In the figure, 1 is a blower, 2 is a high-performance filter, 3 is a blowout nozzle, 4 is a medium-performance filter, 5 is a start switch, 6 is a box, 7 and 8 are doors, 9 is a timer, and 10A is a stair-type tread. It is.
