Abstract

The present invention is a bath which circulates and recycles a multiple mineral solution. The solution is released from the bathtub, filtered at the hair collector and the filtration device, sterilized at the electrolytic sterilizer, and returned to the tub. Non-metallic pipe is used along the circulation route. The electrolytic sterilizer employs several electrode panels which are placed perpendicular to the direction of flow of the solution. The filtration device features a rubber lining in the portions which come into contact with the solution, and has inside of it a dish onto which is lain filter sand. With the use of this invention, it becomes possible to repeatedly use and reuse a highly viscous solution containing multiple minerals as the recycling fluid, jams become infrequent, the filtration and reverse cleansing procedures become less time consuming, and the solution can be effectively sterilized.

Claims4

Dependent claims

A circulatory bathing system for use with a multiple mineral solution which has as its principal features:

(a) pipe means, composed of non-metallic material, for circulating solution released from a bathtub;
(b) an electrolytic sterilizer for disinfecting said solution, comprising several electrode panels lying perpendicular to the direction of fluid flow;
(c) a hair collector for removing hair from said solution;
and
(d) a filtration device for removing impurities in the solution, comprising a cylinder provided with a rubber lining on portions thereof which contact said solution, a dish provided inside said cylinder onto which is lain sand for filtering said solution, a circulatory route provided above said filter sand connecting to said hair collector, and a reverse cleansing route provided below said filter sand, wherein said electrode panels of said electrolytic sterilizer comprise a titanium alloy and are constructed in a mesh shape, and an electric current of between about 1 to 3A flows through said electrode panel.
