PURIFYING FILTER FOR BATHTUB WATER

PURPOSE:To remove impurities, fine refuse and soil, and further particularly to prevent the cloudiness in a bathtub water purifying device. CONSTITUTION:In a filter body A which a lot of filter surface materials 1 consisting of woven fabrics or nonwoven fabrics are bent in pleats to form and by which impurities, fine refuse and soil, are filtered off from bathtub water, an inner flow passage 5 through which a part of the bathtub water is passed without being filtered and the other bathtub water is passed with being filtered is formed. In the inner flow passage 5, a pressure automatic opening/closing means 8 which opens under the condition not less than a prescribed pressure is installed. In this way, the impurities, the fine refuse and the soil, can be filtered off to some extent, and the cloudiness is also prevented. The filter body A is not easily clogged, and the filter replacement time is saved. Even if the filter body is clogged, since the flow rate is secured, the pump is not burdened and the filtration efficiency is improved, and compact equipment can be manufactured.
