<p>PURPOSE:To prevent scattering of dust from a waste throw-in port to the outside by forming the charging port to be of a rotary slide type, and discharging the inside air through a gap between double containing boxes. CONSTITUTION:An inner containing box 1 for fixing a waste containing bag 6, and an outer containing box 2 for enclosing the inner containing box 1 are provided, and air is sucked and discharged from a gap between the inner containing box 1 and the outer containing box 2. A cover 4 of a waste throw-in port is of a rotary slide type, and a filter 5 is provided at a suction/discharge port 7. As air flowing from the waste throw-in port is a steady flow discharged from an air discharge port, dust generated when waste is thrown in follows the air flow to be collected by the filter 5, so clean air is discharged. Because the cover 4 of the throw-in port is of the rotary slide type, turbulence of air flow close to it can be restricted to the minimum, so scattering of dust into a clean room to contaminate it can be prevented.</p> |
