タンク等の排出部に排出するか、洗浄液タンクに還流し
、被洗浄物のみを洗浄槽内に残留させる。Function In order to clean the objects to be cleaned, such as printing screens and printed circuit boards, with the above-mentioned structure, after storing the objects to be cleaned in the cleaning tank, the cleaning liquid is poured into the cleaning tank from the cleaning liquid tank. Fill. Then, the object to be cleaned is cleaned using an appropriate cleaning method such as ultrasonic cleaning or rocking cleaning. When the cleaning of the object to be cleaned is completed, the cleaning liquid in the cleaning tank is discharged to a discharge part such as a drain tank. Otherwise, the cleaning liquid is returned to the tank, leaving only the items to be cleaned in the cleaning tank.
