JPH0229528A - Cylindrical air shower - Google Patents

Abstract

PURPOSE:To avoid an accident, where a door suddenly projects out, without requiring a large space for an entrance door and an exit door by building a cylindrical air shower room, and forming the entrance and the exit doors into a large door of a circular shape that is rotated to open and close the entrance and the exit. CONSTITUTION:An air shower room 1 is cylindrical, and equipped with air jet nozzles 12... on its inner wall 11. An entrance 2 is located next to an exit 3. A large door 4 that covers both the entrance and the exit is of a circular arc shape along the inner wall 11, formed into a linked body, and rotated by an automatic opening-closing driving unit 5. When an entrant comes, the large door 4 rotates towards the exit 3 side to open the entrance 2. When there is a person who leaves the room, the large door 4 rotates towards the entrance 2 side to open the exit 3.

Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a cylindrical air shower.

``Prior art'' Air showers are usually box-shaped like telephone booths that can accommodate one to several people, and have entrances and exits located at the front and back, and doors that open outward at these entrances and exits. Air jet nozzles are arranged on the inner surfaces of both side walls, laminar flow outlets are provided on the entire surface of the ceiling, and the floor is formed into an inlet consisting of a ventilated floor.

When someone enters the room, an air jet is first ejected from the air jet nozzle to knock off the dust adhering to the person's body, and then a laminar flow is released from the laminar air outlet on the entire surface of the ceiling. Air is blown out and the dust is removed to the suction port.

[Problem to be solved by the invention] However, in this case, a considerable amount of door space is required in the front and back, and since the door opens outward, there is a risk that the door will unexpectedly pop out toward the person entering the room if automated. Furthermore, each of the two doors requires an automatic opening/closing device, which has the disadvantage of increasing costs.

The present invention seeks to eliminate such conventional drawbacks.

"Means for Solving the Problems" The present invention forms a cylindrical air shower room in which an inlet and an outlet are adjacent to each other, and the doors of the inlet and outlet are arranged in a circular arc shape and a series of large doors along the circumference of the air shower room. It is formed on the door and configured to open and close as desired by rotating in the arc direction of the door.

``Operation'' With the above configuration, when opening the entrance, move the large door to one side, and when opening the exit, move the large door to the other side.
All you have to do is rotate each one. When opening both doors in an emergency, etc., it is only necessary to turn the door widely to either direction.

"Example" The drawings illustrate embodiments of the invention.

In the figure, l is an air shower room, 2 is an entrance of the air shower room, 3 is an exit of the air shower room, 4 is a large door that closes the entrance and exit, and 5 is an automatic opening/closing device for the large cough door. be.

The air shower room l has a cylindrical shape, has a large number of air jet nozzles 12 disposed on the inner circumferential wall 11, has laminar flow outlets (not shown) on the ceiling, and has an air chamber 13 behind these. The air chamber is connected to an air supply bag W (not shown) that supplies clean air;
A turntable 15 is provided in the center of the floor 14, a suction port 16 is formed by grating, the suction port is connected to an air exhaust device (not shown), and an annular opening 17 is provided around the floor 14. There is.

The entrance 2 and exit 03 of the air shower room are placed next to each other, and the large door 4 that closes them is arranged inside in the form of a series of circular arcs along the inner circumference 2+1 of the air shower room. The automatic opening/closing device 5 is configured to rotate it in the arc direction.

The automatic opening/closing device 5 has a ring body 51 arranged corresponding to the annular opening 17, and a plurality of guide rollers 52 under the floor.
It is rotatably supported by ..., and is placed under the floor.
A drive pulley 54 and an idler 55,55 rotated by a motor 53 are arranged, and a wire 5 is connected between these and the ring body 51.
6 are hung across each other, and the ring body 51 is rotated in both directions via a wire 56 by the rotation of the drive pulley 54, and the large door 4 is erected at a suitable position on the ring body 51.

With the above configuration, the large door 4 is opened and closed by the automatic opening/closing device 5.
Figure 41. As shown in ~■, the inlet 2 and outlet 3 are opened and closed. That is, 1. The closed state of the entrance 2 and the exit 3 is shown when the Air Yawer is in use and when it is not in use.

(2) When someone enters the room, the large door 4 rotates toward the exit 3 and opens the entrance 2.

(2) When someone leaves the room, the large door 4 rotates toward the entrance 2 and opens the exit 3.

(2) In the event of an emergency, the large door 4 can be largely rotated to either side to open the entrance 2 and exit 3.

Then, the person entering the room gets on the turntable 15 and plays 1-
It rotates several times, but during that time, air jets are ejected from all the air jet nozzles 12 at the same time, knocking off the dust adhering to the body of the person entering the room, and continuing to blow out the laminar flow outlet on the entire surface of the ceiling. A laminar flow of air is ejected from the entire surface, and the dust is discharged to the suction port 16.

Note that an air jet nozzle may also be provided in the large ffTh4 (in that case, each air jet nozzle may be connected to the air chamber 13 as appropriate, and the automatic opening/closing device 5 may be replaced with a wire and a gear It may be a means or a means with other things.

"Effects of the Invention" According to the present invention, a large door is placed around the air shower room (11).
Since the door can be opened and closed by rotating at the same time, a large door space is not required for the entrance and exit, and there is no danger of the door jumping out to the child.

Furthermore, since one large door is rotated corresponding to the entrance and exit, only one automatic opening/closing device is required, which reduces costs.
