Abstract

PURPOSE: To prevent the re-sticking of fine garbage to dishes and prevent the clogging of a filter by inverting a damper position immediately before the final rinsing process of an operation program, and guiding the water from a washing tub to a half section of a filter chamber surrounded by the fine-mesh filter. CONSTITUTION: The upper end of an inner lever 29 presses a switching arm 23 to the left as shown by a broken line, and a damper 22 interlocked on the opposite side to its rotary shaft is rotated into contact with a stopper 19b on the right side by an upper end section 22c. The flow of the rinsing water entering from an opening 12 is shifted to a fine-mesh filter section 17 side. The fine garbage retained in the water is completely removed by the fine-mesh filter section 17, and the filtered water is sent to a washing pump 27 through the suction port 28b of a straightening tub 40, a suction pipe 34b, and a liaison port 27b. The straightening tub 40 is divided into two by the partial outer wall 15a of a filter chamber 15, and the washing water flows in a passage different from that in the previous processes.
