Description

The present invention relates to an apparatus for sterilizing and purifying bath water.

<Prior Art and Its Problems> Conventionally, for sterilizing bath water, a sterilizing agent was added or sterilization was performed with ozone, but there were problems such as maintenance problems and system complexity.

Further, Japanese Patent Laid-Open No. 56-31489 discloses a sterilizer using an electrolyzer. However, sterilization is likely to be insufficient with a simple operation by electrolysis.

Therefore, an object of the present invention is to provide a bath water sterilization / purification device that eliminates the conventional drawbacks and can easily and surely perform bath water sterilization and purification.

<Means for Solving the Problem> In order to achieve the above object, the bath water sterilizing and purifying apparatus of the present invention has a receiving space for receiving the circulating water in the case in the middle of the circulation path for circulating the bath water to the outside. A bath water sterilizing and purifying apparatus provided with an electrolyzer for performing electrolysis by dividing the water entering each electrode side into each other by dividing it into an anode side and a cathode side by a diaphragm, A reaction tank having a receiving space larger than the receiving space is continuously and integrally formed on the downstream side of the electrolyzer, and the water on each side of the electrodes in the electrolyzer enters the reaction tank in an isolated state as it is. Thus, the diaphragm of the electrolyzer is configured to extend into the receiving space of the reaction tank.

<Operation> According to the features of the present invention, the bath water flowing through the circulation path is electrolyzed by the electrolyzer. On the anode side of the electrolyzer, the hydrogen ion concentration increases and becomes acidic water, and NaCl from human sweat is separated to generate chlorine gas, resulting in a sterilizing effect. Similarly, it becomes alkaline water on the cathode side, and has some sterilizing effect. That is, the bath water is sterilized by electrolysis.

Since the water on the anode side and the water on the cathode side of the electrolyzer are prevented from easily mixing with each other by the diaphragm, the sterilizing effect by the acidic water and the alkaline water generated at both electrodes is improved.

In particular, according to the feature of the present invention, since the reaction tank having a large receiving space which is continuously separated by the diaphragm is provided on the downstream side of the electrolyzer, the acidic water and alkaline water generated in the electrolyzer are formed. Each of them will continue to be sufficiently kept in an acidic and alkaline state in a wide reaction tank for a while. Therefore, the circulating water is sterilized by the acid and alkali generated for a sufficient time.

Further, in the present invention, the reaction tank is continuously formed integrally with the electrolyzer and the diaphragm is also configured to extend the diaphragm of the electrolyzer into the reaction tank. Since it can be integrally manufactured as one unit, the manufacturing is easy and the cost is low, and the piping work is easy.

<Embodiment> FIG. 1 is an overall configuration diagram of an apparatus embodying the present invention, and FIG. 2 is a sectional view showing a main part of the apparatus.

A circulation path 2 and a circulation pump 3 are provided for a bathtub (including a water tank such as a pool), and an electrolyzer 4 is provided in the middle of the circulation path 2.
(80) is provided. A filter 5 can be provided in the circulation path 2. In addition, the circulation path 2 may be provided with a reheating means, an air bubble introducing means, or the like. The bath water from the bath 1 is returned to the bath 1 through the filter 5 and the electrolyzer 4 by driving the circulation pump 3. And meanwhile, filter 5
And is electrolyzed by the electrolyzer 4.

The electrolyzer 4 is provided with an anode and a cathode in a receiving space inside a case, and bath water passes between them. By applying a DC voltage between the anode and the cathode, electrolysis of bath water is performed, hydrogen ions increase in the water on the anode side to become acidic, and components such as human sweat contained in bath water. Nacl is generated as chlorine gas on the anode side. Sterilization is performed with this acidic water and chlorine gas. Since the Nacl and other electrolytes increase as the bath water becomes dirty, the electrolysis current naturally increases and decreases accordingly, and sterilization corresponding to the dirt can be automatically performed. In addition, hydrogen ions increase on the cathode side to become alkaline, and sterilization is performed.

Referring to FIG. 2, the electrolyzer 80 has a receiving space 80b for receiving circulating water in a case 80a.
An anode 81 and a cathode 82 are provided on both left and right sides of b. A diaphragm 83 is provided in the center of the receiving space 80b in the flow path direction. The circulating water from the circulation path 2 enters the case 80a and is divided into a space 80b on the side of the anode 81 and a space 80b on the side of the cathode 82 which are partitioned by the diaphragm 83.

A reaction tank 90 is continuously formed on the downstream side of the electrolyzer 80. This reaction tank (90) is configured such that its case 90a is continuous with the case 80a of the electrolyzer 80, and the receiving space 90b in the case 90a is larger than the receiving space 80b of the electrolyzer 80. I am configuring. And a diaphragm in the direction of the flow path provided in the center of the receiving space 90b.
The diaphragm 93 of the electrolyzer 80 is made integral by extending the diaphragm 83.

The circulating water that has entered the electrolyzer 80 and is split into the anode 81 side and the cathode 82 side is electrolyzed by both electrodes 81 and 82 to become acidic water and alkaline water, respectively, and further flows into the reaction tank 90. Since the receiving space 90b in the reaction tank 90 is larger than the receiving space 80b of the electrolyzer 80 and is continuously separated by the diaphragm 93, the electrolyzer 80
The acidic water and the alkaline water obtained in step 1 above are kept in a sufficient space in the reaction tank 90 without being subsequently mixed. As a result, the sterilization with acidic water and the sterilization with alkaline water are carried out with sufficient contact place and time. The circulating water from the reaction tank 90 is mixed again and neutralized, and then returns to the bath 1.

The electrolyzer 80 and the reaction tank 90 are continuously and integrally configured, and also the diaphragm 83 of the electrolyzer 80 and the diaphragm 93 of the reaction tank 90.
Since the and are configured as an integral body, they can be easily manufactured, the manufacturing cost can be reduced, and the piping construction can be easily performed.

<Effect> The present invention is configured as described above, and according to the bath water sterilizing and purifying apparatus of claim 1, a reaction tank having a receiving space larger than the receiving space of the electrolyzer is provided on the downstream side of the electrolyzer. In addition, the diaphragm of the electrolyzer is extended into the receiving space of the reaction tank so that the water on each electrode side in the electrolyzer enters the reaction tank in an isolated state as it is. With this configuration, the acidic water and the alkaline water produced by the electrolyzer can be retained in a separated state with sufficient contact location and time, and the sterilizing effect can be sufficiently improved. Therefore, sterilization can be performed even when the concentration of acid and alkali is low.

Also, since the electrolyzer and the reaction tank are continuously and integrally configured, and the diaphragm of the electrolyzer and the diaphragm of the reaction tank are integrally configured, the manufacturing is easy and the cost is low. Etc. becomes easy.
