Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alkaline ionized water generator, and more particularly to a treatment of waste water at the time of water purification.

[0002]

2. Description of the Related Art An alkaline ionized water generator is provided with an alkaline ionized water discharge passage and an acidic ionized water discharge passage for extracting alkaline ionized water and acidic ionized water from an electrolytic cell for electrolysis, respectively. In general, tap water is supplied after that (see, for example, Japanese Patent Application Laid-Open No. 7-227596). In the alkaline ionized water generator having such a configuration, when water is supplied in a state where the power to the electrolytic cell is cut off and the electrolysis function is lost, only the water purification function is exhibited, and the water is purified through the water purifier. Water is discharged outside through both the alkaline ionized water discharge passage and the acidic ionized water discharge passage through the electrolytic cell.

[0003] The above-mentioned acidic ionized water discharge passage is discharged to the outside as wastewater unless the acidic ionized water is actively required. Therefore, conventionally, even when only the water purification function is exhibited as described above, Purified water discharged through the acidic ionized water discharge passage is also discharged to the outside as wastewater.

[0004]

However, in the case where only the water purification function is performed as described above, the discharge to the outside, even if a part of the water purification function, is carried out in comparison with the amount of supplied tap water. There is a problem that the amount of water decreases. As a countermeasure, it is usually considered that the acidic ionized water discharge passage is closed by some means so that all purified water is discharged from the alkaline ionized water discharge passage.

However, if the acidic ionized water discharge passage is closed, a pressure difference is generated between the alkaline ionized water generation chamber and the acidic ionized water generation chamber provided with the diaphragm in the electrolytic cell, and the diaphragm is damaged. There is a risk.

Accordingly, the present invention is to provide an alkaline ionized water generator in which the amount of water does not decrease even when only the water purification function is exhibited, and which does not adversely affect the diaphragm. Make it an issue.

[0007]

In order to solve the above-mentioned problems, the present invention provides an alkaline ionized water discharge passage and an acidic ionized water discharge passage for extracting alkali ionized water and acidic ionized water from an electrolytic cell for electrolysis. In the alkaline ionized water generator provided so that tap water is supplied to the electrolytic cell through a water purifier, an inlet and a first outlet of a three-way valve are connected in the middle of any one of the discharge passages, A configuration is adopted in which the second outlet of the three-way valve is joined to the other discharge passage.

According to the above configuration, when electricity is supplied to the electrolytic cell to generate alkaline ionized water, the three-way valve is set to a non-operating state. Then, the alkaline ionized water and the acidic ionized water are discharged separately to the alkaline ionized water discharge passage and the acidic ionized water discharge passage, respectively, as usual.

On the other hand, when only purified water is to be discharged, the supply of electricity to the electrolytic cell is stopped and the three-way valve is operated to switch the passage. Then, a part of the purified water that has passed through the water purifier and passes through the three-way valve is combined with the purified water discharged through the other discharge passage, so that the entire amount of the purified water is discharged through one discharge passage to the outside. Is discharged.

[0010] At this time, there is no pressure difference between the two production chambers sandwiching the diaphragm inside the electrolytic cell, so that there is no influence on the diaphragm.

The above object can be achieved by connecting the three-way valve to either the acidic ionized water discharge passage or the alkaline ionized water discharge passage. However, the three-way valve is generally connected to the acidic ionized water discharge passage. . The valve body of the three-way valve is driven by an actuator such as an electromagnet.

As another means for achieving the above object, an alkaline ionized water discharge passage and an acidic ionized water discharge passage for taking out alkaline ionized water and acidic ionized water respectively from an electrolytic cell for performing electrolysis are provided. In the alkaline ionized water generator configured to supply tap water through a water purifier, one of the discharge passages has a first passage having an on-off valve, and a second passage having a valve chamber in the middle. And the outlet of the valve chamber is merged with the other discharge passage, and a spherical valve is mounted on a valve hole provided on the bottom surface of the valve chamber, and the second passage is closed by its own weight. Can be adopted. In this case,
A configuration in which a check valve is provided at the outlet of the valve chamber of the second passage may be employed.

The alkaline ionized water generator of the first embodiment is as described above. In order to generate alkaline ionized water by this, the water supply port 14 is connected to a faucet of a tap to supply electricity to the electrolytic cell 6. Then, tap water is supplied to the electromagnet 7 of the three-way valve 8 in a state where power is not supplied. The tap water is purified in the water purifier 3 and the calcium in the calcium addition car 15 is added. The purified water is supplied to the inner tank 35 and the outer tank 36 of the electrolytic tank 6.

Further, a check valve 49 is provided at the outlet of the valve chamber 45 so as to allow the flow in the direction exiting from the valve chamber 45 and prevent the flow in the direction entering from the alkaline ionized water discharge passage 9 side.

It should be noted that even if there is a backflow from the alkaline ionized water discharge passage 9 into the valve chamber 45, the spherical valve 48
, The check valve 49 may be omitted.

The second embodiment is as described above.
The operation as an alkaline ionized water generator is the same as that of the first embodiment, and the acidic ionized water is discharged from the acidic ionized water discharge port 13 by opening the on-off valve 44. At this time, the spherical valve 48 causes the valve hole 46
Is closed.

On the other hand, when only the water purification function is exhibited,
The on-off valve 44 is closed. Then, the purified water discharged from the inner tank 35 pushes up the spherical valve 48 (see FIG. 4B), passes through the valve hole 46, the valve chamber 45, and the check valve 49, and purifies the alkaline ionized water discharge passage 9. The water is merged with water, and the whole amount is discharged from the alkali ion water discharge port 11. In this case, the weight of the spherical valve 48 is appropriately selected so as not to generate a certain pressure or more in the inner tank 35.

[0033]

As described above, according to the present invention, when only purified water is discharged using the alkali ion generator, the three-way valve is switched or the on-off valve is closed, and the alkaline ion water discharge passage is connected to the acidic water. Purified water discharged separately from the ion water discharge passage can be joined to one of the discharge passages. As a result, the entire amount of purified water can be discharged from one discharge port, and no discharge passage is closed, so that there is no possibility of adversely affecting the diaphragm of the electrolytic cell.
