Abstract
A dry cleaning apparatus which causes cleaning agent to fly in a gas current to impact an object to be cleaned so as to remove extraneous substance attached to the object includes a cleaning tank defining an interior space for accommodating the cleaning agent and the object with the attached extraneous substance, an inflow unit configured to guide a gas current into the cleaning tank through an inlet, an aspiration unit configured to discharge gas from the cleaning tank through an aspiration opening, and a separation unit disposed between the interior space of the cleaning tank and both the inflow unit and the aspiration unit, the separation unit having openings that allow the gas and the extraneous substance to pass through but do not allow the cleaning agent to pass through, wherein the inlet, the aspiration opening, and the separation unit are configured such that relative motion is created between the separation unit and both the inlet and the aspiration opening.
