Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a clean air generator that can be moved from place to place at any time, and the room in which it is moved can be used as a clean room.

(Prior Art) The development of conventional clean benches and the like is well known, and there is also a movable type as described in, for example, Japanese Utility Model Application Publication No. 151448/1983.

The movable sterile table in the above example is equipped with a foldable hood and curtain, which is expanded and clean air is blown into the interior through a hose to locally form a sterile room.

(Problems to be Solved by the Invention) The above-mentioned conventional devices are intended to form a sterile area within a limited range, and do not have the function of making the entire room a sterile area.

(Means for solving the problem) The purpose of this invention is to create a so-called clean room by sterilizing the entire room into which a movable air generator is installed, and by opening an air intake port on one side. , a blower with an air intake side connected to the air intake side and a filter installed on the exhaust side is installed in a movable machine housing with a moving wheel on the bottom surface, and a clean air blowing chamber is installed on the secondary side of the filter. A part of the outer wall of the blow-off chamber is made up of a plurality of removable panels including a panel provided with an operation panel and a panel with a blow-off port formed therein.

(Example) In the drawings, reference numeral 1 denotes a movable machine housing having a moving wheel 2 at the bottom, an air intake port 3 opened on one side thereof, and a removable filter 4 provided in the opening.

A blower 5 whose intake side communicates with the air intake port 3 side is installed inside the machine casing 1, and a filter 6 is installed on the exhaust side of the blower 5. In the illustrated example, a medium-performance filter 6a is located at the front, and a filter 6 is located at the rear of the blower 5. 6 shows a polymerized high performance filter 6b.

On the secondary side of the filter 6, a clean air blowing chamber 8 is formed which is separated from the machine room in which the blower 5 is installed by a partition wall 7, and a part of the outer wall 9 of the chamber 8 can be attached to and detached from a plurality of chambers having the same shape and size. It consisted of 10 panels.

That is, as shown in the illustrated example, the blowing chamber 8 has, for example, the sides opposite to the machine room and a part of the top surface open, and the open portions are closed with a plurality of detachable panels 10 to form an outer wall 9. Configured.

The plurality of panel members 10 are formed of blind boards without openings, and one of them is equipped with a switchboard 11 for controlling the operation of the internal mechanism, and another one is equipped with a clean air outlet 12. Assume that it is open.

In the illustrated example, the air outlet 12 has a multistage slit shape made of louvers, but the air blowing distance can be extended by making this into a single elongated air outlet, or by arranging an appropriate number of them in the form of a nozzle. etc. are optional.

In addition, the top surface of the machine casing 1, except for the open upper part of the blowout chamber 8, is opened to serve as an inspection port 13, and an opening/closing lid 14 is attached to this, and the air intake port 3 can also be used as an inspection port by removing the filter 4. I decided to do so. A handrail frame 15 is provided around the upper surface of the opening/closing lid 14 to be used as a grip for moving the machine and to prevent objects placed on the lid 14 from falling off.

Further, each panel 10 may be attached or detached by any means such as an external fitting type using a locking screw as shown in the illustrated example.

(Function) The clean air generator according to the present invention is used by moving it from the wheel 2 to any place at any time, and by operating the blower 5 in the room where it is moved, indoor air is sucked and the air is purified through the filter 6. The clean air is blown into the chamber 8 as air, and the clean air is blown into the room from the outlet 12 of the panel 10 with the outlet 12 opened.By circulating the air, the room can be made into a clean room. By selecting the positions of the panels 10 having the air outlets 12 and replacing the panels with each other, clean air can be supplied into the working area of the machine, as shown in FIGS. 1 and 3, for example. The air outlet 12 is located at the upper side of the machine casing 1,
Alternatively, as shown in FIG. 4, it can be used at the lower side position or, although not shown, as the upper surface open position of the blowout chamber 8, and the switchboard 11 can also be used at an appropriate position by replacing the panels 10 with each other. did.

(Effects of the invention) When using the invention, it is possible to move the aircraft and use a desired room as a clean room, and instantly convert the existing room into a clean room, so there is no need to construct a special expensive clean room. It is economical to use, easy and convenient to handle, and since the outer wall of the outlet chamber is made up of multiple panels of the same shape and size, including a panel with a switchboard and an outlet opening, the panels can be interchanged. This has the effect that the positions of the switchboard and the air outlet can be freely changed depending on the situation.
