Abstract
PURPOSE: To prevent harmful substances from leaking to the outside by installing multiple number of free-to-tilt dampers under the cabinet fan and forming many divided blast passages.
CONSTITUTION: Many dampers 12 are installed, in contiguity with the filter 5, under the fan 6 of the cabinet 1. The damper blades 12 can be rotated by the center shaft 13 which is connected to the drive motor 15 via link mechanism 14 so that the blades 12 can be stopped, by controlling the motor 15, at a titled position with a proper angle. The damper 12 has divided draft passages 12a whose opening increases from the door 3 to the empty chamber 2; the damper 12 is connected to the motor 15 via connection circuit 16 so that both the door 3 and the blades 12 can be titled. When the door 3 is open by activating the fan 6, the dampers 12 are driven through the motor 15 so that the air speed is higher at the inlet and lower as the air goes deep. A nearly constant air speed is provided by closing the door 3. Thus harmful substance such as bacteria, even if used, cannot escape out of the cabinet.
