APPARATUS FOR FILTERING BATHTUB WATER

摘要

PURPOSE:To surely collect dust even by a filter relatively low in flow passage resistance and to make it possible to develop capacity over a long period of time, by providing an ultrasonic generator to the upstream side of the filter provided on the way of the reciprocating recirculation passage of hot water in a bathtub. CONSTITUTION:An ultrasonic generator 5 is provided to the upstream side of the filter 4 provided on the way of the reciprocating recirculation passage 2 of hot water in a bathtub 1. Because the ultrasonic wave from the ultrasonic generator 5 impinges against hot water passing through the filter 4 from the bathtub 1, fine dust and bacteria or dead bacteria, etc. suspended in hot water cling together and flocculate to be grown into large particles. These particles grown to a certain degree can be sufficiently collected even by the filter having a larger mesh size.
