Description

[Detailed explanation of the invention] (Field of industrial application) This invention is highly effective in eliminating dust from clothes in lockers in changing rooms connected to clean rooms, or in dehumidifying and ventilating locker rooms in sports facilities. The present invention relates to an air purifying device that exhibits the following characteristics.

(Conventional technology and its problems) The remarkable development of ultra-precision industry requires higher and higher levels of cleanliness in clean rooms, and this requirement cannot be met simply by improving the clean room structure and filters, and there is a problem with the introduction of dust into the clean room. Prevention must be strengthened.

When entering the clean room, employees change into work clothes in a changing room attached to the clean room, and use an air shower to remove dust from their bodies and work clothes before entering the room.

However, the lockers in the changing rooms store clothes and shoes with a lot of dust on them, and each time the locker door is opened, the dust inside the lockers floats outside and attaches to the worker, causing an air shower. However, it was difficult to completely prevent dust from entering the clean room.

In addition, changing rooms at sports facilities such as tennis clubs and swimming schools are used by people who have taken a shower, so the floors become wet and the humidity is high, causing mold to grow in the changing rooms and making them unclean.

(Means for solving the problem) In view of the above, the present invention aims to provide a device that turns the changing room itself into an air-cleaning space, strengthens the prevention of dust from being brought into the clean room, or improves the prevention of dust in the changing room of a sports facility. The purpose is to prevent mold from forming.

In the present invention, a locker 3 with a door 31 and a back plate 32 configured to allow ventilation is installed in a room, a ventilation space 21 is formed behind the back of the locker 3 along the wall of the room, and the ceiling 11 is communicated with the ventilation space 21. The filter is equipped with a filter 6 and an outlet 61.

(Operations and Effects) The air in the locker room passes through the locker, passes through the intake port, reaches the filter, is purified, and is discharged back into the locker room from the outlet port.

Inside the Locker 3, air flows from the door 31 side to the back plate 32 side, so dust generated from clothes inside the Locker 3 flows from the Locker 3 to the rear ventilation space 21 and is removed, leaving the door side as usual. There is no leakage into the changing room, and the air in the changing room is kept clean.

If implemented in changing rooms for clean rooms, it will be highly effective in preventing dust from entering the clean room, and if implemented in changing rooms for sports facilities,
Prevents mold from growing in the changing room.

(Example) Fig. 1 shows a changing room 1 connected to a clean room (not shown), with an air shower room on the other side of the door 12 and a clean room (neither shown) on the other side of the room. It's summery.

In the changing room 1, two-stage lockers 3, 3 are installed near one side wall, and partition plates 34, 34 are installed between the upper locker 3 and the ceiling 1 and between the lower locker and the floor. It is partitioned off.

A horizontally long slit-shaped ventilation hole 30 is provided at the bottom of each door 31 of the lockers 3, 3, and the back plate 32 is made of punching metal or the like, and has many through holes 33.
has been established.

The back plate 32 of the above rock cars 3 and 3 and the interior wall 2
A ventilation space 21 that reaches from the floor to the ceiling 11 between
is formed.

A filter 6 provided through the ceiling 11 and the upper end of the ventilation space 21 are connected by a duct 4, and an air blower 5 is connected to the duct 4.

The filter 6 is a well-known HEPA filter developed for dust removal in clean rooms.

However, the air inside changing room 1 is
1 through the ventilation hole 30 of the back plate 32, is led to the duct 4 through the ventilation space 21, passes through the filter 6, flows back into the room from the outlet 61, and repeats this cycle. . Since the filter 6 is a Hepa filter that blocks the passage of fine particles, the changing room itself becomes a clean room.

Inside the Locker 3, air flows from the door 31 side to the back plate 32 side, so dust generated from clothes etc. stored in the Locker flows from the back plate 32 to the ventilation space 21 at the rear, and flows out from the Locker door 31. The inside of changing room 1 is kept clean.

FIG. 2 is a sectional view of the changing room 1 of the sports facility, and FIG. 3 is a plan view of the same.

Inside the room, the backs of multi-stage lockers 3, 3 are placed against the wall of the room, and the lower locker 3 is placed slightly above the floor to form a space 22 between it and the floor.

A ventilation hole 30 and a through hole 33 are provided in the door 31 and back plate 32 of the lockers 3, 3.

Further, a ventilation space 21 is formed between the back plate 32 of the locker 3 and the wall surface of the room, and the ventilation space 21 communicates with a space 22 between the lower locker 3 and the floor surface.

The hollow panel 2 is connected to the filter 6 on the ceiling 11 of the changing room 1 by the duct 4 with a blower as described above.

The air in the changing room 1 passes through the rocker 3 and is sucked into the hollow panel 2 as described above, passes through the filter 6 and flows into the room again.

Indoor air is also sucked in from the space 22 between the lower rocker 3 and the floor, so that ventilation above the floor is improved.

Therefore, I took a shower and got my body wet.
Even if you enter the changing room and get the floor wet, it dries in a short time, keeping it clean and preventing mold from forming due to moisture.

It goes without saying that the configuration of each part of the present invention is not limited to the above-mentioned embodiments, but can be modified in various ways within the technical scope of the claims for utility model registration.
