Abstract

PURPOSE:To permit to remove dust and contamination, adhered to a work piece upon processing, effectively under saving energy by a method wherein clean air, different from the clean air in a working space, is obtained from the port of a supplying means with a high speed. CONSTITUTION:An airflow resisting means 10, having an opening 10a at a part thereof, is provided at the downstream side of an air cleaning filter 4 and the opening 10a is provided with a connecting port 11, connected to a clean air supplying means 12. The airflow resisting means 10 is constituted of a substance, having air resistance of some degree, or a non-woven cloth, for example. The supplying means 12 may be a hose, for example. The size of the opening 10a is regulated so that a part of clean air, shown by arrow signs in the diagram, is flowed out of the supplying means 12 with about 1m/s flow speed in order to clean the working space 7. Accordingly, the flow speed is high, therefore, dust and contamination, generated upon working and adhered to the work piece, may be removed effectively by blowing the clean air against the work piece through the supplying means 12.

One embodiment will be described based on FIG. 1. In the figure, arrows represent air flow. Reference numeral 1 designates a clean bench, in which external air passes through a pre-filter 2 and is sent to an air purifying filter 4 by a blower 3. Here, the air is purified and sent to the work space 8. The work space is illuminated by the fluorescent lamp 6. 6 is a diffuser plate, 8 is a work object, and 9 is a work table. In the work space 7, the clean air is laminarized and the flow velocity is 0.2 m/s to 0.5 m/g.

Processed. However, the work object 8 may be contaminated by dust generated during processing. On the other hand, since the laminar flow velocity of clean air is slow at 0.2 to 0.5 m/s, the dust generated during processing cannot be removed quickly and tends to adhere, and it is difficult to effectively remove the dust. Blow away,
The drawback was that it could not be removed.

An air supply means is connected, and the area of the opening and the area of the supply means mouth are determined so that the velocity of clean air from the supply means mouth is approximately 1 rV/8. Then, the fast clean air that comes out from the supply means blows off and removes the particles and contaminants that are generated on the workpiece during processing.
This allows the work object to be kept clean at all times.

Components that are the same as those in the conventional example will be designated by the same numbers and will not be described further. As shown in FIGS. 2 to 4, an air flow resistance means 1° having an aperture 10a in a portion is provided downstream of the air purifying filter 4, and the aperture 10a has a
A connection port 11 with a clean air supply means 12 is provided, and the supply means 12 is connected thereto. The air flow resistance means 1o having an aperture 10a in a portion thereof may be made of any material as long as it has a certain degree of air resistance, such as a nonwoven fabric. Further, the supply means 12 is also exemplified by a hose. A part of the clean air shown by the arrow for cleaning the working space 7 is outputted from the supply means 12 at a flow rate of about 1 rrVS.
The size of the opening 10-a of the air flow resistance means 10 is adjusted. Therefore, since the flow rate is as fast as 1rrV/s, dust is generated during processing and dust and contaminants attached to the workpiece are 1. It can be effectively removed by applying clean air to the supply means 12.
