Description

Clean Bench with Shelves {Clean Bench with Shelves}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a clean bench, and more particularly, to a clean bench in which a shelf is installed inside to enable a work space to be used more widely and effectively.

The Clean Bench is an experimental device that provides a local working space in which a sterile, dust-free environment is maintained, allowing various experiments and observations in aseptic conditions inside. Normally, the aseptic working space is realized by circulating air in which the foreign substances (including bacteria) are removed in the case (work space).

The clean bench is used to perform various precision work such as semiconductor processing, chemical experiment, microbial cultivation, bacterial cultivation and the like since it provides an aseptic and nonvolatile environment. Especially, it is a device that is used almost indispensably in bio-related R & D and manufacturing processes where aseptic environment is essential.

The worker will work on the clean bench's workspace by placing experimental objects such as cells, various instruments, containers, and badges. However, if a certain level of foreign substances such as bacteria are introduced into the work space, an error may occur in the experiment or observation, or even the test object may be killed due to the contamination. Therefore, the work area of the clean bench should be kept very clean and impurities should not be allowed to flow above a certain level. To this end, the clean bench is supplied with clean air to the workspace.

The clean bench is composed of a horizontal layer type in which laminar clean air is supplied from the front side to a worker in accordance with the air flow type, a vertical layer type in which the vertical air is vertically supplied from the inner ceiling to the bottom side of the work space, An air circulation type in which air is circulated upward and an air exhaust type in which air flows vertically and then is sucked from the bottom side and exhausted upward.

For example, the exhaust type clean bench includes a filter mounted on the upper side of the work space to filter a part of the air blown by the blower to supply clean air to the lower part, A blower for forcedly sucking in the vicinity of the floor or inlet (operator side) and blowing upward between the outer case and the working space, and a discharge port for discharging a part of the blown air to the outside . Therefore, the air circulated during the clean bench operation is filtered by the clean air through the filter, and then flows from the upper side to the lower side of the working space. The air passing through the working space is forcibly transferred through the blower, And some of the air is exhausted to the outside through the exhaust port, so that the working space is kept sterile by the clean air supplied to the working space.

In any type, clean air is supplied by removing high-performance filter (HEPA / ULPA Fiter) including foreign matter such as bacteria, so the inside of the clean bench usually becomes a clean zone of Clean Room Class 100 or less. On the other hand, especially in the field of biotechnology, if the organism to be tested is toxic, infectious, or has a specific gene, it may cause diseases or disturb the ecology of organisms including humans, A predetermined filter device or a sterilizing device is provided to purify the exhaust gas.

On the other hand, in the field of biotechnology, in the course of the clean bench work, a variety of experimental tools are used for working such as bacteria, cells, tissues (hereinafter referred to as "bacteria"), newly prepared mediums, alcohol lamps, pipettes and containers . In some cases, it may be necessary to handle dozens to hundreds of petri dishes or triangular flasks containing medium. Fig. 1 shows a photograph showing a work space inside the clean bench in which a large number of experimental tools and a discharge container are loaded and are in a complicated state (normal operation state).

Since the floor of the clean bench work space is narrow, when there are a lot of exhaust containers or experimental tools (collectively called "experimental tools"), put some of the experimental tools on the clean bench and put the rest on the outside carts. Or alternatively, a method of replacing an external device or a multilayered rack is provided in a clean bench work space, and experimental tools are stacked thereon.

In the case of replacing the internal and external test tools, the operator must not only disinfect the hands and the test tool which were exposed to the outside every time they are replaced, but also the operator's hands and arms repeatedly move in and out of the work space There is a possibility that foreign pollutants may flow into the work space. ③ In the process of replacing, the context of the work may be cut off, which may lead to errors in experiments sensitive to changes in micro conditions. The method of using racks has the advantage that many experimental tools can be loaded in the work space inside the clean bench, but the work space is narrowed by encroaching a part of the floor, and in particular, the rack is not fixed, There is a problem that the experimental tool loaded in the rack falls to the floor or the rack is collapsed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a clean bench capable of safely and effectively expanding a fixed work space and loading many experimental tools at a time.

According to an aspect of the present invention, there is provided a clean bench for discharging purified clean air into a work space to make a work space sterile, wherein a shelf is mounted on a side wall of the work space It is about a clean bench.

As described above, according to the present invention, since many experimental tools can be loaded at one time during the clean bench operation, it is possible to minimize unnecessary external exposure during the operation, and to prevent pollution and increase the convenience of the operator.

In addition, according to the present invention, it is possible to consistently perform a set of operations without replacing experimental tools in and out of the work space, thereby maintaining the precision of the work.
