DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garment stocker for keeping a garment (dustless garment) worn in a clean room or the like while keeping it clean.

[0002]

2. Description of the Related Art Conventionally, garments such as dust-free garments worn in a clean working space such as a clean room or a bio-clean room are stored in a clean state in order to keep them in a clean state. Stockers are used.

In this garment stocker, a vinyl curtain is stretched at the front opening of the stocker so that the garment can be taken in and out, and at the same time, clean air is constantly fed into the stocker to maintain the internal space at a positive pressure. This prevents dust from entering from outside and adheres to the garment. However, in such a garment stocker, the vinyl curtain must be opened and closed every time the garment is put in and taken out, which is difficult in terms of ease of use.

Further, since the garment is stored in the stocker as it is after wearing, there is a problem that dust particles attached to the inside and outside of the garment enter the stocker together with the garment.

Furthermore, because of the all-fresh system, air constantly flows out of the stocker to the outside, and the above-mentioned dust particles and odors attached to the garment diffuse to the outside.
Conversely, there was also a problem that external odor was sucked into the stocker and translocated to the garment.

[0006]

A ceiling partition 11 is provided on the lower side, which is the outlet side of 0, to form a cavity 12 (positive pressure section).

The above-mentioned ceiling partition 11 has an air outlet 11a composed of a number of small holes or slits having a uniform distribution over the entire surface.
And at the portion along the upper edge of the opening 4,
An air outlet 11b for generating an air curtain airflow flowing down along the opening surface is formed. In order for the airflow from the air outlet 11b to form an air curtain airflow, the area and the opening ratio of each opening of the air outlet 11a are made smaller than those of the air outlet 11b, or another air blowing is performed. It is necessary to distribute a sufficient air flow rate to the air outlet 11b by providing a fan or the like.

The floor plate constituting a part of the internal partition wall 6 is formed by a punching board having a large number of small holes formed on the entire surface thereof, and serves as an air recovery port 6 b for the cavity 7.

The part is slidably supported. Thus, when the garment G is taken in and out of the small space 22, the garment G is pulled out toward the front side from the garment hooking position in the center of the small space.
Can be hung.

Further, the opening 2 of the ceiling partition 24a is formed.
An air outlet 27 for generating an air curtain airflow that flows down along the opening surface is formed at a portion along the upper edge of the opening 0.

A partition 24 near the floor of the small space 22
Is provided with an air recovery port 31 and an air intake port 32 is provided near the lower end of the outer casing 23, and a pre-filter is attached to the air intake port 32. The cavity 25 includes a lower cavity 25b (negative pressure section) provided with the air recovery port 31 and the air intake 32 by the partition wall 33, and an upper cavity 25a.
(Positive pressure section), and a blower fan 34 is provided in the lower cavity 25b, and an air purification filter 35 is provided in the upper cavity 25a. Incidentally, reference numeral 36 denotes a vinyl noren similar to 16.

Next, the operation will be described based on the above embodiment.

In the stocker section 1, the air sucked into the cavity 7 through the air recovery port 6 b and the air intake 13 by the operation of the blower fan 9 is purified by the air purifying filter 8 and sent to the cavity 12 by pressure. , Air outlet 11
a is blown out into the storage space 3 and a part of the air is blown out from the air outlet 11b to the opening 4 to form an air curtain airflow flowing down along the opening 4.

The opening 4 is shielded by the air curtain airflow, so that the air blown out from the air outlet 11a is prevented from flowing out and diffusing from the opening 4, so that the air enters the storage space 3. Ceiling air outlet 11
The air flow from a to the air collecting port 6b of the floorboard is always generated, and only the air in the storage space 3 is circulated through the air collecting port 6b, so that the outside air does not enter through the opening 4.

Thus, dust particles are prevented from entering the storage space 3, and the inside of the storage space 3 has a cleanness M3.5-
It is always kept in a clean state of about M4.5 (Class 100 to 1000). In addition, the deodorizing filter provided in the air inlet 13 prevents the external odor from entering the stocker unit 2 and the odor of the garment G itself from flowing out. In spite of these advantages, the front surface of the stocker 1 is the entire opening 4, so that the garment G can be easily put in and out of the storage space 3.

When the garment G after being worn is stored in the stocker portion 1, the air curtain airflow is blown through the opening 4 so that dust particles together with the garment G can be prevented from entering the storage space 3 to some extent. . Even if the dust particles enter the storage space 3, the dust particles are collected by the air cleaning filter 8 by the airflow circulating through the air recovery port 6b, so that the cleanliness in the storage space 3 is reduced. I will not do it.

However, depending on the working conditions of wearing the garment G and the cleanliness required inside and outside the stocker, there is a possibility that the garment G may be contaminated. In such a case, the garment G can be positively dust-removed in the air jet unit 2 as described below, and then stored in the stocker unit 1.

First, the garment G after wearing is put on a hanger H
And hooked on the pipe hanger 28 of the air jet unit 2. Then, the pipe hanger 28 is slid and moved to the center of the small space 22 of the air jet unit 2.

In this state, when the blower fan 34 is operated by operating the switch 37, the air sucked into the lower cavity 25b through the air recovery port 31 and the air intake port 32 is cleaned by the air cleaning filter 35. Upper cavity 25a
And injected into the small space 22 from the bunker nozzle 26.

Then, as shown in FIG. 4, the air injected from the center bunker nozzle 26c is mainly blown into the garment G from the opening of the neck of the garment G,
Exhausted from cuffs and hem. On the other hand, the air injected from the bunker nozzles 26s on both sides is blown against both shoulders of the garment G. By vibrating the garment G from both the inner and outer surfaces by these two systems of air injection, dust particles attached to the garment G are reliably blown off. Then, the dust particles blown down are collected in the air collecting port 3.
1 is sucked into the lower cavity 25b and collected by the air purification filter 35.

At this time, a part of the air fed into the upper cavity 25a is blown out from the air outlet 27, and flows down along the opening 20 of the small space 22 in the same manner as in the case of the stocker 1 described above. The opening 20 is blocked by the air curtain air flow, and the dust particles scattered in the small space 22 are prevented from being scattered outside.

After the dust is removed in the air jet section 2, the normally closed sliding door 21 is opened to communicate the small space 22 of the air jet section 2 with the storage space 3 of the stocker section 1. As shown in FIG. 3, the garment G is moved into the storage space 3 of the stocker unit 1 through the communication portion, and is hooked on the pipe hanger 14. As a result, the garment G can be stored in the storage space 3 without being taken out of the air curtain airflow 17.
This is advantageous in preventing dust from re-adhering to the garment G, preventing contamination of the garment G, and maintaining cleanliness in the storage space 3.

In the above embodiment, the case where the front surface of the stocker unit 1 is the entire opening 4 is shown, but the garment G is stored only from the air jet unit 2, and the garment G When only taking out is performed, the lower half of the front surface of the stocker unit 1 may be closed at about 1/2 to 1/3, and only the upper part may be opened. In addition to the sliding door 21 of the sliding type, a roll shutter, a bellows type shutter, or the like can be used as the partition member.

[0031]

The front opening type garment stocker of the present invention is constructed as described above, and has the following effects.

A garment storage space is formed inside, and an opening for taking in and out the garment is formed in the front of the storage space, and a ceiling partition having an opening for blowing clean air is provided on the ceiling. Are provided with an air intake, and an inner partition is provided inside the outer casing on the back and / or side of the storage space to form a double structure to provide air between the air intake of the floor and the ceiling between the layers. While forming a flow path, an air purifying filter and a blower fan are provided above the outlet of the ceiling, and the air sucked through the air inlet, the air flow path and the air inlet opened to the outside is filtered by the air purifying filter. An air car that is cleaned so that it can be blown out of the outlet into the storage space, and that a part of the ceiling partition wall along the front opening of the storage space flows down along the opening of the storage space. The airflow outlet allows for easy insertion and removal of garments because there is no shielding member such as a vinyl curtain at the opening, and dust can enter the storage space from the opening due to the air curtain airflow. In addition, the air blown out from the ceiling into the storage space is recirculated from the air intake of the floor to the air purification filter. Outflow of dust and odor to the outside is suppressed.

Also, on one side of the garment storage space,
Partitioned by the storage space and an openable partition member,
In addition, a small space for air jets is formed on the front side of the garment storage space side and a series of openings is formed. In addition to providing air curtain airflow outlets, a blower fan and an air flow path for feeding air sucked in from the lower portion and outside of the small space to the air jet nozzle and the air curtain airflow outlet through an air cleaning filter are provided. Therefore, after dust is removed from the garment by an air jet, the partition member can be opened and communicated with the stocker side to be stored as it is. Adhesion can be prevented, and an effect of preventing contamination of the garment and the stocker can be expected.
