業が阻害される。[Detailed description of the invention] For workbenches that handle dangerous pathogens or harmful substances, or that are used for assembling sensitive equipment, etc., a blower and a filter are installed inside the workbench cabinet, leaving an opening for work. Filtered clean air is released into the work room surrounded by walls. For this reason, the vibrations caused by the blower impede precise weight measurements to determine the dosage of chemicals, or precise assembly work using a microscope.

ａで囲んだ作業室６を形成してある。 Reference numeral 1 designates a workbench main body, in which a blower 3, an air supply filter 4, and an exhaust filter 5 are installed in a cabinet 2, and a partition wall 2 is installed at the front of the cabinet 2 except for the front surface.
A work chamber 6 surrounded by a is formed.

る。 The upper half of the front surface of the work chamber 6 is covered with a transparent door 7, and a work opening 8 is formed under the transparent door 7.
On the other hand, an exhaust slit 9 is provided at the front of the bottom plate 6a of the work chamber 6 as an air intake port, and the exhaust slit 9 communicates with the intake port 3a of the blower 3.
The blower 3 takes in the air in the work chamber 6 through the exhaust slit 9 and the outside air that is drawn in through the work opening 8 and forms part of the air curtain airflow through its intake port 3a, and discharges it from its discharge port 3a. The water is then supplied to the filter 4 in the upper part of the working chamber via the duct 10. The air supply filter 4 cleans the air supplied from the blower 3 and releases it into the working chamber 6 from the upper part of the working chamber. An exhaust filter 5 placed on the top of the cabinet 2 cleans a portion of the air supplied by the blower 3 and exhausts it outside the cabinet via a duct and exhaust system (not shown), creating negative pressure in the work chamber 6. Keep it. This keeps the inside of the work room 6 clean and prevents dangerous pathogens inside the work room from leaking outside. The workbench main body 1 is manufactured in this state as a standard workbench with an air filter, and is used for normal work where vibrations on the workbench are not a problem.

縁されている。 Reference numeral 11 denotes an auxiliary workbench, which is removably inserted into the lower part of the workroom 6 through the work opening 8 of the workbench main body 1 to form a gap between the workroom bottom plate 6a and the partition wall 2a.
A work plate 12 located with gaps g 1 and g 2 and a base 13
A is installed on the floor separately from the workbench main body 1, and both arm portions 13b extending from both sides of the base pass through both sides of the work opening 8 to support the workbench 12. , is vibration-insulated from the workbench main body 1.

で発生した汚染物質の拡散を有効に防止する。 The work plate 12 is formed to have a smaller size than the bottom plate of the work chamber, and has a large number of holes 12a bored in the plate surface as an air circulation means, as shown in FIG.
A clean air flow flows through the work plate 12 in a substantially laminar flow state through the holes 12a. As a result, dust generated on the work plate 12 is immediately sucked into the nearest hole 12a and sucked into the exhaust slit 9, thereby preventing the spread of contamination on the work plate. The air circulation means is not limited to a large number of holes 12a, and may be something like a grating. The work plate 12 is located with a gap g 2 between it and the partition wall 2a, and is also located with a gap g 1 between it and the bottom plate 6a of the work chamber. As a result, an air curtain is formed around the work plate 12, thereby effectively preventing the diffusion of contaminants generated on the work plate 12.

る。 According to this embodiment, since the work plate 12 is provided with a large number of holes as air circulation means, the filter 4
Even if the clean air blown from the air collides with the work plate 12 as shown by the arrow A, the vibration of the work plate 12 due to the airflow can be suppressed since there is little air resistance. Further, by pulling out the auxiliary workbench 11 from the workroom 6, the workbench can be used as a normal cleaning workbench without any modification. Therefore, the manufacturer can improve productivity by manufacturing the workbench main body as a standard product and supplying the auxiliary workbench 11 as an option. Furthermore, on the user side, the workbench can be used in two ways, a non-vibration type and a standard type, by attaching and detaching the auxiliary workbench 11, improving usability.

る。 According to the present invention, by inserting an auxiliary workbench into the working chamber of the workbench with an air filter, the standard workbench with an air filter can be easily used as a vibration-free workbench with an air filter without changing the configuration. By providing the work plate with air circulation means, it is possible to obtain a work table with an air filter that can prevent cross contamination on the work plate.
