Abstract: An object of the present invention is to efficiently perform a series of processing including washing in which, for example, different types of clothes or a large volume of clothes etc. are washed and thereafter arranged in order. The clothes etc. are sortably stored in a washing basket (A) for storing the clothes etc. hung on hangers by hanging them vertically, a washing basket (B) for storing the clothes etc. hung on hangers by stacking them horizontally, and a washing basket (C) for storing the clothes etc. by folding them up and stacking them on each other. Pre-processing is performed such that after these washing baskets have beet charged into a pre-processing chamber (1) and the pre-processing chamber (1) has been evacuated to remove gases such as air contained in clearances in the clothes etc., deaerated washing fluid is introduced into the pre-processing chamber (1) to immerse the clothes etc. in the washing fluid.

Abstract: This is an ultrasonic washing technique to enhance, when an object to be washed is subjected to ultrasonic washing, the efficiency of charging and discharging the object to be washed in and out of a washing tank while preventing the apparatus from getting larger in the vertical direction. An inlet and an outlet are provided on the side wall of the washing tank, with closable doors and, after the object to be washed, carried along an upstream shift route is put in through the inlet, it is shut with the door for into a sealed closure, cleaning liquid deaerated in a storage tank is let into a washing tank to subject the object to be washed to ultrasonic washing.
