ULTRSONIC WASHING EQUIPMENT AND ULTRASONIC WASHING METHOD

摘要

An ultrasonic washing method capable of increasing the efficiency of the retrieval and storage of a washed object from and into a washing tank when the washed object is washed by ultrasonic wave and preventing the size of the washing equipment from being vertically increased, comprising the steps of providing an inlet (6) and an outlet (7) in the side walls of the washing tank (2) and doors (6h) and (7h) are formed openable, putting, from the inlet (6), the washed object (fed body (8)) fed in a feed route (3) on the upstream side, closing the inlet (6) by the door (6h) for sealing, leading cleaning solvent deaerated in a storage tank into the washing tank (2), washing the washed object by ultrasonic wave, returning the cleaning solvent in the washing tank (2) to the storage tank, opening the door (7h) at the outlet (7), delivering the washed object (fed body (8)) from the outlet (7) to the side through a feed route (4) on the downstream side, and repeating the steps above.
