Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a disassembled clean unit, and more particularly to a clean unit that can form an air curtain flow to form a clean area.

[Conventional technology]

Conventionally, when performing cleaning work to partition a space to form a clean space, first a framework surrounding the space is formed using a single pipe material, a sheet is placed over this to form a space, and a small A clean space was created by placing a purifier.

However, in this method of creating a clean space, a framework is first formed using a single tube for scaffolding in order to distribute the sheets in a pentahedral shape, and then the sheet is placed on top of it to form the space to be cleaned. Not only does the work take a lot of time, but the space covered by the sheet needs to be kept clean! The drawback is that it takes a long time to get stuck in, and the work efficiency is not good.

In addition, when creating a clean space and entering and exiting the space,
There was a drawback that it was necessary to remove sheets etc. each time to go in and out, which was inconvenient for transporting people or goods.

[Problem that the invention seeks to solve]

For this reason, the applicant has arranged a clean unit equipped with an air inlet and an air outlet and a built-in filter surrounding the space to be cleaned, and arranged the air outlet and the air inlet in correspondence with each other. We proposed a clean area forming device that surrounds a clean space using an air curtain style to form a clean area.

However, as mentioned above, such a lean unit is equipped with parts such as an air inlet, an air outlet, a medium-performance filter, a high-performance filter, an axial fan, etc., and the size of the unit itself becomes large, and it can be assembled on site. Unavoidably, there was a drawback that the assembly work required a long time. In particular, this trend has the disadvantage that when a large-capacity clean area is formed, the clean unit itself naturally becomes large, and each part must be disassembled and assembled on site.

The present invention has been made in view of these circumstances, and consists of a clean unit that can be disassembled and divided into a plurality of units, each disassembled unit being manufactured at a factory, and the disassembled clean unit being disassembled at the site. The purpose of this project is to propose a disassembled clean unit that can be constructed simply by combining the two parts, making on-site work easier.

[Means for solving problems]

In order to achieve the above object, the present invention provides a first clean unit assembly including a first air suction port, a medium-performance filter through which air sucked from the first air suction port passes, and a second clean unit assembly. An air suction port, a high-performance filter through which air passing through a medium-performance filter and air sucked from a second air suction port pass, and a first fan that sucks air from the first and second air suction ports. a second clean unit assembly, an air outlet provided on a surface perpendicular to the first and second air suction ports, and a second fan that blows out air from the air outlet. consisting of an assembly;
The first, second, and third clean unit assemblies are assembled to form a substantially rectangular parallelepiped shape as a whole.

[Effect]

The present invention provides a first clean unit assembly with a first
The second clean unit assembly has a second air suction port, a high-performance filter, and a first fan, and the third clean unit assembly has an air blow-off port and a medium-performance filter. At the factory, the first, second, and third clean unit assemblies for each army were manufactured separately and delivered to the site.
At the site, the first, second, and third clean unit assemblies were combined to form a generally rectangular parallelepiped, and a plurality of these were arranged around the space to be cleaned to form an air curtain flow. It is something.
