Abstract

PURPOSE:To avoid accumulation and attachment of dusts while clean shoes are stored and prevent bad odor from staying in the storage box by recycling the air added fresh air partially through the storage box. CONSTITUTION:The air sent in by a blower 1 for air recycling is removed of dusts by a main filter 8 to become clean air, blows out of the ceiling section, and passes through a clean air passage 9 and among clean shoes 5 received in a clean shoes receiving shelf 7 and clean shoes receiving shelf 7. The air is then recovered to a return chamber 4 through an air passage opening 3. A fresh air taken in from a fresh air intake opening 11 is added to the air thus recovered. The air then passes through a prefilter 2 and is sent into a blower for air recycling. Because air ventilation holes 3 can be adjusted the respective sizes of openings by a blast regulating device 10 according to the positions of clean shoes receiving shelves 7, it is possible to cycle clean air uniformly all over the clean shoes receiving shelves.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a clean shoe storage for intermittently storing clean shoes worn in a clean room for manufacturing semiconductor devices or the like outside the clean room.

Conventional technology Clean shoes worn inside the clean room are stored in a changing room adjacent to the clean room, as shown in Figure 2. It was stored in a box-shaped shoe box. In the figure, there is a shoe storage box for one pair, 13 is the door,
14 is a door knob.

Melting point to be solved by the invention In the conventional box-shaped shoe box as described above, the air cleanliness inside the box-shaped shoe box is at the same level as in the changing room in which the box-shaped shoe box is installed. The cleanliness of the changing rooms is not high as there is a lot of dust coming from clothes.

Therefore, dust in the air accumulates and adheres to the clean shoes while they are being stored, and eventually adheres to the clean shoes and is carried into the cleaning room.

Since the air inside the box-shaped shoe box is stagnant, there is a bad odor caused by repeated use of clean shoes, which is unfavorable in terms of environmental hygiene.

The purpose of the present invention is to solve these problems by storing clean shoes in clean air even when they are stored, preventing dust from accumulating and adhering to them, and preventing foul odors from lingering by replacing the air. That is.

Means for Solving the Problems The present invention has a clean shoe storage chamber and an air return chamber separated by a vertical partition plate, and a main filter is connected to the upper part of the storage chamber. a plurality of clean shoe storage shelves protruding substantially horizontally into the storage chamber from the partition plate and arranged in a vertical direction; a ventilation hole communicating with the return chamber, a door on the front surface of the storage chamber opposite to the partition plate, a ventilation path between the door and the storage shelf, and an air passage in the upper part of the return chamber; To provide a clean shoe storage, comprising a circulating air blower that blows air to the upper part of the storage chamber through a pre-filter, and a fresh air intake port leading to the outside at a lower side of the return chamber. .

Function The air inside the clean shoe storage is adjusted so that it is kept at a higher pressure than the outside air by adding some fresh air, and the clean air that has been removed with a filter is circulated through the clean shoe storage. This prevents dust from entering outside the storage, for example through gaps in the door. In addition, since fresh air is constantly taken in, the bad odor emitted from the clean shoes being used is radiated outside the clean shoe storage, and the bad odor does not drift inside the clean shoe storage.

Furthermore, when the clean shoes are not stored, relatively clean air circulates within the clean shoe storage, extending the life of the dust filter.

Embodiment FIG. 1 is a sectional view of a clean shoe storage cabinet showing an embodiment of the present invention.

The air sent by the circulating air blower 1 becomes clean air from which dust is removed by the main filter 8 and is blown out from the ceiling, passes through the clean air passage 9, and is stored in the clean shoe storage shelf 7 and the clean shoe storage shelf 7. It passes through the gap between the clean shoes 5 and is collected into the return chamber 4 through the ventilation hole 3. The recovered air is added with fresh air taken in from the fresh air intake port 11,
- Passes through the pre-filter 2 and is sent to the circulating air blower.

By adjusting the size of each ventilation hole 3 using the air volume regulator 1o according to the position of the clean shoe storage shelf, clean air can be uniformly circulated throughout the clean shoe storage shelf. . The air volume regulator 7 may be in the form of a plate, for example, and may have a shape that blocks the air hole 3 to achieve its purpose.

The door 6 for taking in and taking out clean shoes may cover the entire clean shoe storage shelf 7, or may be provided for each clean shoe storage shelf.

Effects of the Invention As is clear from the description of one embodiment of the present invention, by circulating clean air to which some fresh air is added through the clean shoe storage, accumulation of dust while storing clean shoes can be prevented. , yet can prevent bad odors from drifting.
