<p>Provided in a dipping washing tank (3) which contains therein a cleansing liquid (2) are a plurality of fluid injection nozzles (4a, 4b, 4c, 4d) serving to jet a fluid which causes the cleansing liquid (2) to forcibly flow, e.g. a cleansing liquid, compressed air and a mixed fluid thereof, said fluid injection nozzles being disposed in parallel to a tank wall, e.g. a bottom surface (1a) of the dipping washing tank (3). The plurality of fluid injection nozzles (4) are divided into two groups (e.g. 4a and 4d, and 4b and 4c) so that fluid injection timing is alternately switched between the respective groups of the plurality of fluid injection nozzles (4) by an injection timing control device (6) to substantially reverse a direction of forced flow of the cleansing liquid (2). Alternatively, the fluid injection nozzles are made movable to substantially reverse a direction of forced flow of the cleansing liquid. Accordingly, it is possible to uniformly wash an entire surface of an article being washed irrespective of a part and a position of the article being washed.</p> |
