以下、図面に基づいて説明する。第1図は本発明による
装置の系統図であり、1は浴槽、7は浄化部、9は空気
導入口である。Hereinafter, description will be given with reference to the drawings. FIG. 1 is a system diagram of the apparatus according to the present invention, in which 1 is a bath, 7 is a purifying unit, and 9 is an air inlet.
浴槽1は、金属、ホーロー、プラスチック、コンクリー

も勿論使用される。The bathtub 1 is of a type which is made of metal, enamel, plastic, concrete, wood, etc. and is used in ordinary households. Of course, those having heating means such as an outer pot and an inner pot may be used.

わない。Reference numeral 2 is a first water supply pipe, one end of which is immersed in bath water 3 in the bathtub, and the other end of which is connected to the purifying section 7 through a suction port 4, a pump 5 and a secondary filter 6 of the bath water. The water 3 is sucked and supplied to the purification unit 7. This suction port is provided with an appropriate opening which does not cause suction resistance, and a primary filter 8 is provided at the tip thereof. The primary filter is for preventing relatively large solid matter such as sand, hair, and solid organic matter from entering the circulation system. For example, a sponge or a non-woven fabric may be used. The material does not matter as long as it is not suitable for bath water.

代えても良い。An air inlet 9 is provided in the first water pipe 2. In particular, a negative pressure compared to the atmospheric pressure can be utilized between the suction port 4 and the pump 5 because of the suction force of the pump, which is convenient for introducing air. However, the object of the present invention can be achieved even if an inlet is provided between the pump and the purifying unit and compressed air is pushed in. As for the air to be introduced, oxygen may be simply replaced with this, since oxygen is abundantly adsorbed in the circulating bath water as described above, and microorganisms are thereby proliferated.

を変えても良い。The air introducing port 9 is constituted by a small through hole provided in the wall of the water supply pipe, and the negative pressure of the pump sucks air from the through hole. The water pipe may be made of stainless steel, brass, or sometimes plastic as long as it can withstand the atmosphere in the bathroom, and the material is not specified. The diameter of the small holes is determined by the pressure difference when introducing and the amount of bath water. The dissolved oxygen value (DO) in the bath water is 1.5 to 2.0 from some of the examples carried out.
It is desirable that the volume is at least ml / l, the amount of bath water is 180 l, and the differential pressure is 1000.
In the example of mlAq, the diameter of the small holes was satisfied with φ0.1 to φ2.5. In order to introduce or push in the most efficient air amount, some small-diameter inlets may be prepared, or sometimes a needle valve or the like may be installed in place to change the air amount.

第1の送水管に設けたことが好ましい。The pump is a power source for sucking in the bath water and returning it to the bathtub again through the secondary filter and the purification section.In addition, the air introduced into the circulating bath water from the inlet is thoroughly stirred inside the pump to Since it also has a function of promoting air adsorption to the first water supply pipe, it is preferable to provide the first water supply pipe.

特に麦飯石のような水中にミネラル分を溶出する鉱物を
用いる場合は浴水の浄化に相乗してより快適な入浴環境
が得られる。In particular, when a mineral such as barley stone that dissolves out minerals in water is used, a more comfortable bathing environment can be obtained by synergizing with the purification of bath water.

たりすることも可能である。A second water supply pipe 11 is connected to the outlet of the purifying unit, and the other end thereof is connected to an outlet 12 provided in the bath so that purified bath water is delivered to the bath. A heater 13 is provided in the second water supply pipe and is a heater for compensating the temperature of the bath water that drops due to circulation. Hold. Although the heat source is electric power in the example of the present invention, it may be gas or kerosene by providing a heat exchanger, for example.

生させることにより入浴の快適性を増長させる。At the outlet, the circulating bath water pumped from the pump through the purification unit is blown out into the bathtub. The blowout port appropriately agitates the bath water by the force of the ejected bath water, and at the same time enhances the bathing comfort by generating air bubbles by entraining air by an ejector structure (not shown).

This bath water passes through the secondary filter and reaches the purification section together with organic substances and the like that cause the bath water dirty water. Microorganisms fixed to the carrier in the purification unit receive organic matter and oxygen-rich bath water, and contact with each other to actively oxidize and digest organic matter. The organic matter becomes carbon dioxide gas and water and diffuses in the air or in the bath water, thus producing the effect of purifying the bath water.

The amount of bath water was about 180 liters and was adjusted to about 41 ° C by a heater. Further, the flow rate of the water supply pipe 1 was set to 20 l / min, and about 30 cc / l of air was introduced into this bath water from the air inlet. After adding organic matter to the bath water in this state, the chemical oxygen demand value in the bath water (hereinafter referred to as COD), the dissolved oxygen value (hereinafter referred to as DO),
The number of microorganisms was measured. The results are shown in FIG. As is clear from the figure, the number of microorganisms increases rapidly, the COD value decreases rapidly with it, and the bath water is purified. It consumes a lot of oxygen, which reduces it. As a comparative example, introduction of air was stopped and the same test was conducted.
The results are shown in FIG. In this case, the amount of decrease in COD is small, and when comparing the values after 8 hours, for example, it is about four times as large as when air is introduced, indicating that purification is difficult to proceed.
なお各測定値は次のようにして測定した。Each measured value was measured as follows.
