Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of electrolyzed water producing apparatus, and specifically, the electrolyzed water produced in a diaphragm-type electrolyzer is supplied to an acidic water tank and an alkaline water tank, respectively. The present invention relates to a batch-type electrolyzed water generator configured to obtain the electrolyzed water of interest while circulating the electrolyzed water.

[0002]

2. Description of the Related Art In a conventional electrolyzed water generator, as shown in, for example, Japanese Patent Laid-Open No. 7-39876, first, a fixed volume of raw water corresponding to the size of an electrolyzer is charged and electrolyzed for electrolysis. For example, as shown in Japanese Patent Application Laid-Open No. 4-76752, an electrolyzer and an acidic water tank and an alkaline water tank are separately provided so that acidic water and alkaline water are electrolyzed. There are continuous types that are produced while circulating between the tank and each tank.

[0003]

Among the above-mentioned conventional electrolyzed water producing devices, the former batch type is for producing electrolyzed water by putting a fixed amount of raw water in an electrolyzer.
At the time of one generation, only the capacity of the device, that is, the capacity of the electrolytic cell can generate the electrolyzed water. There is a hassle of having to repeat
When more electrolyzed water is required at one time, it is necessary to prepare a plurality of the same generators to simultaneously generate water, which is very uneconomical.

Further, the latter continuous type electrolyzed water producing apparatus is constructed such that anode water (acidic water) and cathode water (alkaline) are circulated between the electrolyzer and each tank by pumps, respectively. , The difference in water level between the anode side and the cathode side occurs due to the difference in the performance of each pump and the difference in the amount of electrolyzed water used, and due to this difference in the water level, acidic water and alkaline water are mixed. There was a problem of sexualization.

That is, the positive electrode chamber and the negative electrode chamber of the electrolytic cell are partitioned by a porous diaphragm. If the hole diameter of this porous membrane is large, the state becomes close to a non-separated state and acidic water and alkaline water are separated. Since they are mixed with each other, it is necessary to use a porous film whose hole diameter is made as small as possible.

However, in the production of a porous membrane, the smaller the hole diameter, the higher the production cost and the higher cost. Therefore, in reality, both water have a relatively small hole diameter so that they cannot be easily mixed with each other. Electrolysis is performed using a large-price, low-cost porous membrane, but if a difference in water level occurs between the two chambers as described above, the pressure difference easily mixes acidic water and alkaline water. There was a problem of becoming neutral.

In addition, since the above-mentioned conventional continuous type electrolyzed water producing device is constructed as an integrated type in which each tank and the electrolyzer are connected by a pipe, the size of the tank is changed. There is a problem that the capacity of the electrolyzed water cannot be changed easily.In addition, in the continuous type electrolyzed water generator that sends the electrolyzed water to an intake port different from the tank, the In addition, an electromagnetic switching valve or pump for switching the flow path of the electrolyzed water from the tank to the water inlet side is additionally required, which causes a problem that the water supply device becomes complicated and the cost is increased.

Therefore, the technical problem of the present invention is that the required amount of electrolyzed water can be obtained by one electrolyzed water generator, and there is no difference in water level between the positive and negative chambers. In this way, a porous membrane with a relatively large hole diameter can be used as a diaphragm, and the capacity of the generated electrolytic water can be easily changed. Furthermore, the water supply device has a simple structure and the cost of the entire device is reduced. The object of the present invention is to provide an electrolyzed water generator that enables the above.

The feature is that a freely-supplied water supply pump is attached. (Claim 3 )

According to the means of claim 1 described in the above (1), the water levels of the acidic water and the alkaline water in the positive and negative chambers are always kept constant by the overflow from the overflow discharge pipe. Therefore, there is no difference in water level between the two chambers, and therefore, it is possible to use an inexpensive and simple diaphragm having a relatively large hole diameter as a diaphragm for partitioning the two chambers.

Further, according to the means described in (1) above,
Just by switching the rotation direction of the water pump,
Circulate and supply electrolyzed water to the electrolyzer side or send it to the intake side.

According to the second aspect of the invention described in (2) above, the raw water tanks for electrolyzed water (acidic water and alkaline water) are detachably attached to the water supply pipe and the overflow discharge pipes, respectively. Therefore, by exchanging this with a raw water tank having a required capacity according to the purpose, it is possible to generate and use the required amount of electrolyzed water with one generator.

According to the third aspect of the invention described in ( 3 ) above, by using a water supply circuit having an extremely simple structure in which one pump and a total of four check valves are combined, a plurality of water supply circuits can be provided. This makes it possible to switch the electrolyzed water in the raw water tank to both the electrolyzer and the intake port without using a pump or electromagnetic switching valve.

As described above, the above (1)-
By solving the technical problem described above by means of ( 3 ),
It is possible to solve the problems of the prior art.
