  • Patent number: 5307652
    Abstract: A scoop-up portion of scoop means is of a flat plate shape so that water is drained by letting a wash rest on the scoop portion during the transferring operation. The wash is scooped surely in raise/drop washing so that the wash is not caught between the inner peripheral surface and one edge of the scoop-up portion. Also, an auxiliary plate is installed on the back surface of transfer portion of the scoop means to prevent the wash from dropping into the preceding vessel in raise/drop washing. Thus, the crumple washing and beat washing are performed efficiently, and cleanliness is improved.
