IPC: A47L15/42
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent air-sucking in pumps. SOLUTION: Washing water inside a washing water tank 4 is sucked from sucking ports 35 by the pumps 32 and 33 and supplied to vertical washing nozzles 30 by pressure. A filter 51 is arranged by covering the both sucking ports 35. Punch metal 52 is spread on four side surfaces except a top plate 5 in a box shape with an open lower surface and formation is executed to be a size by which the top plate 53 comes out from the upper part of a water level L1 in a washing process. Washing water after being supplied for washing comes down to washing water inside the washing tank 4 but falling washing water is prevented from being hit against the top plate 53 and the water surface of stored washing water in a part where the filter 51 is provided since the top plate 53 of the filter 51 is projected upward from the water level L1 during washing.  Therefore, bubbles generation in washing water is suppressed so that air is prevented from being sucked in the washing pumps 32 and 33.
