Abstract

(57) [Summary] [Purpose] A simple and inexpensive clean bench that can form a local clean work area of about 100 clean at any time on a suitable work surface. [Structure] A fan case with a well-known fan filter unit that can easily obtain clean air is used as a clean air generator with its lower surface as a clean vertical airflow outlet, A clean work space having an open front surface was formed on the lower surface of the pedestal so as to be detachably mounted on the upper surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a clean bench capable of easily forming a clean work area.

[0002]

[Prior art]

 As a clean bench that locally forms a clean work area, a combination of a clean air flow generator and a support that supports the clean air flow at an appropriate height is already known, but it is adapted to the work content. In addition, there are differences in the arrangement of devices in the combination and the connection relationship between them, and the assembling means are generally complicated.

[0003]

[Problems to be solved by the device]

 Therefore, in the case of the conventional type, since the structure becomes complicated, many means are required in the manufacturing process, which inevitably results in high cost and maintenance operation is troublesome.

[0004]

[Means for Solving the Problems]

 In view of the above, the present invention provides a vertical air flow type clean bench which can be easily and locally formed on a table or other suitable base plate at a very low cost. The fan case has a motor-driven fan inside, a filter is installed on the bottom surface of the fan, and the bottom surface has a vertical airflow outlet, and a frame-shaped pedestal of a size large enough to support the fan case. It has a pair of left and right support legs on the lower surface of the pedestal so that it is positioned in the upper position, and it is composed of a combination with a pedestal with at least the lower front surface of the pedestal open. It is characterized in that it is placed on.

[0005]

[Action]

 As shown in the illustrated embodiment, the clean bench according to the present invention is a pedestal of a support base 8 having a fan case 1 having a vertical air flow outlet 5 on its lower surface as a device for generating a clean air flow and having an appropriate height. A clean bench can be easily formed by placing it on the table 9. If this is placed on the table or other work surface a, the lower surface of the pedestal 9 will be in a clean area by the vertical airflow blown from the air outlet 5. It becomes the work space 11, and by enclosing the open surface of the clean work space 11 with the transparent film 13 if necessary, it is possible to easily obtain a local clean bench for cleaning work with the front surface as a work opening. If 1 is separated from the pedestal 9 and attached to the ceiling surface, it can be used as a ceiling-exposed clean bench.

【Example】

 An embodiment of the present invention will be described with reference to the drawings.

The present invention is a fan case 1 used as a device for generating clean air, and the fan case 1 is placed so that the fan case 1 is positioned at an appropriate height and a lower surface thereof locally forms a clean work area. It can be combined with a possible bearing stand.

As is well known, a fan 2 that is rotated by a motor drive, a filter 3 on a lower surface of the fan case 1, and a punching board 4 on a lower surface of the fan case 1 are provided inside the fan case 1 to form a clean laminar air outlet 5. A fan filter unit 6 is provided, and intake ports 7 are provided on both sides of the fan case 1 for sucking outside air through a filter.

The support base 8 used in combination with the fan case 1 is a support base 9 of a size capable of supporting the fan case 1, and a lower surface of the support base 9 so that the support base 8 is at a predetermined height position. In the illustrated example, the left and right support legs 10 each have a vertical leg 10a and a horizontal grounding member 10b continuous to the lower end thereof. The pedestal 9 is integrally projected from the upper part of the both side vertical legs 10a, 10a toward the front side, and the both side vertical legs 10a, 10a are connected and reinforced by the lower horizontal rod 10c. Is opened to form a working space 11 between both side support frames 10 and 10 in which a worker can put his / her both hands into the work space. The work space 11 with an open front is shaped As long as it is made, the configuration such as the one in which the rear part and both sides are closed is arbitrary.

In the figure, reference numeral 12 is a reinforcing material for connecting corners of each connecting member constituting the support 8, and 13 is a transparent film 13 surrounding a part of each open surface of the working space 11 when used as a clean bench. , A is a table or other work table surface on which the clean bench of the present invention is placed in order to locally form a clean area, 14 is a stationary piece having a height adjusting mechanism provided on the lower surface of the receiving table 9, and 15 is a moving caster. Indicates. As shown in FIG. 2, the frame-shaped pedestal 9 and the fan case 1 mounted on the frame-shaped pedestal 9 are detachably fitted to each other at the concavo-convex portions 16 and 17 so as to prevent loosening during the coupling. As the anti-movement means, other suitable means can be adopted.

[Effect of device]

 According to the present invention, a fan case containing a well-known fan filter unit is used as a clean air generator as a device that is simply placed on a suitable workbench to easily form a local clean work area. Since it is a clean bench that is detachably mounted on the pedestal of the pedestal that is installed on the above-mentioned appropriate workbench and works in the clean work space formed on the bottom of the pedestal, the structure is extremely simple and inexpensive. It is easy to handle and can obtain a clean area of at least Class 100, and if necessary, only the fan case can be separated and used as a ceiling hanging type cleaning work device. Have.
