BATHTUB WATER PURIFYING APPARATUS

摘要

PROBLEM TO BE SOLVED: To dissolve the enlargement of a pressure loss due to clogging when used even if a filter area is small. SOLUTION: This bathtub water purifying apparatus is provided with a circulating pump 4 circulating bathtub water 2, a filtering means 6 having a filter 5 removing suspended solids in the bathtub water, and a flow passage selector valve changing over the direction of the bathtub water passing to the filtering means between the outflow and the inflow according to the bathtub water purification or the washing. The water flow passing to the filtering means is a rotational flow turning the filter surface. This constitution can produce the water flow on the filter surface to prevent the clogging of the filter and miniaturize the filter area necessary for the purification. COPYRIGHT: (C)2005,JPO&NCIPI
