The present invention relates to an alkali ion water conditioner as described above. 2. Description of the Related Art In recent years, attention has been paid to the quality of drinking water with the rise of the health boom. In particular, the demand for alkali ion water conditioners capable of obtaining alkali ion water which is considered to be healthy is rapidly increasing. Is growing. Hereinafter, a conventional alkali ion water conditioner will be described with reference to the drawings. FIG. 2 is a schematic diagram showing the internal structure of a conventional alkali ion water conditioner. As shown in FIG. 2, the water supply pipe 2, the cartridge 3, the calcium addition cylinder 4, the electrolysis tank 5, the discharge pipe 6, and the drain pipe 7 are provided, and a water passage connecting them is secured by a hose 18 and a joint 19. I have.
The electrolysis tank 5 has a suction port 8 for sucking water, an electrolysis chamber 10 containing an electrode plate 9, and an electrolysis chamber 12 containing an electrode plate 11, and a discharge port 16 for discharging electrolyzed water in the electrolysis chamber 10. It has a drain port 17 for discharging the electrolyzed water in the electrolysis chamber 12. Further, the electrolyzer 5 has a configuration in which the center of the electrolyzer 10 and the electrolyzer 12 is separated by a diaphragm 15 in a state where the electrolyzer 10 and the bottom of the electrolyzer 12 communicate with each other. The electrode plate 9 and the electrode plate 11 have terminals 13 and 14 projecting out of the electrolytic cell 5 respectively. Discharge port 1
6 is connected to a discharge pipe 6 for feeding the electrolytic water on the discharge side to a point of use, and a drain port 17 is connected to a hose 18 serving as a drainage channel.
After the joints 19 are connected in order, a drain pipe 7 for discharging the drain-side electrolyzed water to the outside of the main body 1 is connected. Fitting 1
Numeral 9 also secures a water passage with the suction port 8 with the valve 20 interposed therebetween, and the valve 20 is normally closed. In order to increase the pH value of the alkaline ionized water, the discharge amount may be reduced and the drainage amount may be increased. However, in consideration of economy, a minimum drainage amount capable of securing a predetermined pH value is set. Normally, the diameter 22 of the drain port 17 is the discharge port 1
6 are smaller than the bore 21. [0005] The flow of water in the alkali ion water purifier constructed as described above will be described. When the alkaline ionized water is used for the purpose, the water supplied from the tap water (not shown) is sucked in from the water supply pipe 2, and after passing through the cartridge 3, calcium is added by the calcium adding cylinder 4 and passed through the inlet 8. And supplied into the electrolytic cell 5. In the electrolysis tank 5, the water is distributed to an electrolysis chamber 10 and an electrolysis chamber 12. Electrolysis room 1
The voltage of the cathode is applied to the terminal 13 of the electrode plate 9 in the electrode 0 and the voltage of the anode is applied to the terminal 14 of the electrode plate 11 in the electrolytic chamber 12. Alkaline ionized water as water is generated, and acidic ionized water as electrolyzed water on the anode side is generated in the electrolytic chamber 12. Next, the alkaline ionized water is supplied to the discharge port 16 and the discharge pipe 6.
The acidic ionized water passes through the drain port 17 and the drain pipe 7 and is discharged or discharged to the outside of the main body 1 according to the dimensional ratio of the diameter 22 of the drain port 17 and the diameter 21 of the discharge port 16. [0006] When the purpose is acidic ionized water, the opposite is the case, and the voltage of the anode is applied to the terminal 13 of the electrode plate 9 and the voltage of the cathode is applied to the terminal 14 of the electrode plate 11. The acidic ion water is discharged from the discharge pipe 6 and the alkaline ion water is discharged or discharged from the drain pipe 7 in accordance with the dimensional ratio of the bores 21 and 22, respectively. By the way, when the electrolysis is continued, the electrode plate 9,
For example, the scale may adhere to the surface 11 and the electrolysis ability may decrease. Also, the life of the electrode plates 9 and 11 is shortened. Therefore, in order to use the alkali ion water conditioner for a long time, the electrode plates 9 and 11 need to be washed. [0008] The washing of the electrode plates 9 and 11 of the alkali ion water purifier is performed by applying voltage to the electrode plates 9 and 11 in the immediately preceding use state while holding water in the electrolytic cell 5 after the completion of water supply. This is performed by applying a reverse voltage. After the washing is completed, the valve 20 is opened, and the water used for washing the inside of the electrolytic cell 5 is discharged out of the main body 1 through the drain pipe 7. [0009] However, the conventional alkali ion water conditioner having the above-described structure has the following problems. When using an alkali ion water purifier, the discharged water is used according to the purpose, and the discharged water is used as it is after being discarded or stored in a container or the like. Normal. However, the amount of the normally discharged water is larger than the amount of the discharged water, and the discharged water receives more energy per unit volume. Therefore, it can be said that the discharged water is more expensive than the discharged water. However, when the water discharged to the container is collected and used later, the drained water will be alkali ionized water or acidic ionized water depending on the contents of the alkali ion water purifier, and these will be mixed. In the recovered water in the container, alkaline ionized water and acidic ionized water are neutralized. Also, if the water used for washing is also joined, the quality of the recovered water will be deteriorated. For this reason, although the water in the container was added with the characteristic of electrolyzed water by an alkali ion water purifier, the characteristic was not usually utilized . [0011] The present invention is intended to solve the above problems, Al
It is an object of the present invention to provide an alkali ion water conditioner that can effectively use, as electrolyzed water, wastewater generated when target electrolyzed water, particularly alkali ion water, of potassium ion water and acidic ion water is used. [0012] In order to achieve the above object, an alkali ion water purifier according to the present invention is characterized in that the drainage channel is formed of an electrolytic cell.
Connected to the suction port via a valve, as well as a drain pipe and recovery
Each is connected to a dedicated pipe via a valve, and the drainage channel
Is formed smaller than the diameter of the discharge pipe, and the valve is opened.
When closed, only the specific electrolyzed water is
Collected, other electrolyzed water and water for washing are drained from drain pipe.
It is characterized by being performed. In the alkali ion water purifier of the present invention, since the drainage channel is connected to the drainage pipe and the dedicated recovery pipe via valves, for example, when it is desired to recover acidic ionized water, When ionic water is used, acidic ionic water can be discharged from a dedicated recovery pipe by switching a valve and stored in a container for recovery while using alkali ion water discharged from a discharge pipe. No acidic ionized water flows into the drain. Conversely, when the acidic ionized water is discharged and used, unnecessary alkali ionized water can be discarded from the discharge pipe by switching the valve, and this can be prevented from being mixed with the container provided in the dedicated recovery pipe.
Further, in the alkali ion water purifier of the present invention, the drainage channel is connected to the suction port of the electrolytic cell via a valve, and is also connected to the collection pipe via a valve. It is possible to mix the washed water into the container without deteriorating the quality of the recovered water. An embodiment of the present invention will now be described with reference to FIG. 1 in the case of recovering acidic ionized water for the purpose of alkaline ionized water. As shown in FIG. 1, a water supply pipe 2, a cartridge 3, a calcium addition cylinder 4, an electrolytic cell 5, a discharge pipe 6, a drain pipe 7, and a recovery pipe 23 are connected. 24. The electrolysis tank 5 has a suction port 8 for sucking water, an electrolysis chamber 10 containing an electrode plate 9, and an electrolysis chamber 12 containing an electrode plate 11, and a discharge port 16 for discharging electrolyzed water in the electrolysis chamber 10. It has a drain port 17 for discharging the electrolyzed water in the electrolysis chamber 12. Further, the electrolytic cell 5
With the electrolysis chamber 10 and the bottom of the electrolysis chamber 12 communicating with each other,
The center of the electrolysis chamber 10 and the electrolysis chamber 12 is separated by a diaphragm 15. The electrode plate 9 and the electrode plate 11 have terminals 13 and 14 projecting out of the electrolytic cell 5, respectively. The discharge port 16 is connected to the discharge pipe 6 for supplying the discharge-side electrolyzed water to the point of use, and the drain port 17 is connected to a hose 18 and a joint 24 which are drain channels in this order. The joint 24 is provided with a valve 25, a valve 26, and a valve 27. The valve 25 is connected to the suction port 8, and the valve 26 is connected to the drain pipe 7 for discharging the drain-side electrolyzed water out of the main body 1. , A valve 27 are connected to the collection dedicated pipe 23. Then, the acidic ionized water is collected in the collection tube 23. To increase the pH value of the alkaline ionized water, the discharge amount from the discharge pipe 6 may be reduced and the discharge amount from the drain pipe 7 may be increased.
The minimum drainage amount that can secure the H value is set, and the diameter 22 of the normal drainage port 17 is smaller than the diameter 21 of the discharge port 16. Now, the flow of water in the alkali ion water purifier constructed as described above will be described. When the alkaline ionized water is used for the purpose, the water supplied from the tap water (not shown) is sucked from the water supply pipe 2, and after passing through the cartridge 3, calcium is added by the calcium adding cylinder 4 and the suction port is provided. 8 into the electrolytic cell 5. In the electrolysis tank 5, the water is distributed to an electrolysis chamber 10 and an electrolysis chamber 12. The voltage of the cathode is applied to the terminal 13 of the electrode plate 9 in the electrolytic chamber 10, and the voltage of the anode is applied to the terminal 14 of the electrode plate 11 in the electrolytic chamber 12. The interior of the electrolysis chamber 12 is divided into alkaline ionized water as the cathodic electrolysis water and the acidic ionized water as the cathodic electrolysis water. The above operation is basically the same between the conventional example and the present embodiment. However, in this embodiment, the alkaline ionized water is discharged through the discharge port 16 and the discharge pipe 6, while the acidic ionized water is discharged through the valves 25 and 26.
Is closed and valve 27 is open, so drain 1
7. The water is discharged through the hose 18, which is a drainage channel, and the collection pipe 23. At this time, the ratio of the alkaline ionized water and the acidic ionized water is determined by the dimensional ratio of the diameter 22 of the drain port 17 and the diameter 21 of the discharge port 16, and
It will be discharged or discharged outside. In this way, acidic ionized water is effectively recovered. Next, when the purpose is acidic ionized water, the procedure is reversed. That is, since the voltage of the anode is applied to the electrode plate 9 and the voltage of the cathode is applied to the electrode plate 11, acidic ion water is discharged from the discharge pipe 6. Also, joint 24
At this time, the valves 25 and 27 are closed and the valve 26 is opened, so that the alkaline ionized water is discharged from the drain pipe 7. The ratio of the acidic ionized water and the alkaline ionized water is determined according to the dimensional ratio of the apertures 21 and 22, respectively. In this case, the alkaline ionized water is discharged as unnecessary. Further, the electrode plate 9 of the alkali ion water conditioner,
The washing of 11 is performed by applying a voltage opposite to the voltage applied in the immediately preceding use state to the electrode plates 9 and 11 while maintaining the water in the electrolytic cell 5 after the completion of the water supply. After the washing is completed, the valves 25 and 26 are opened and the valve 27 is closed in the joint 24, so that the water used for washing in the electrolytic tank 5 is discharged out of the main body 1 through the drain pipe 7. This water is not mixed into the recovered water. The opening and closing of the valves 25, 26, and 27 described above can be automatically performed. That is, when the alkaline ionized water is used, the valve 25 and the valve 2 are automatically selected in accordance with the polarity selection of the electrode plates 9 and 11.
6 is closed and valve 27 is opened. Valves 25, 26, 27
Are preferably solenoid valves. Also, when using acidic ionized water, the valves 25 and 27 are automatically closed and the valve 26 is automatically selected in accordance with the polarity selection of the electrode plates 9 and 11.
Is opened. Further, in the case of cleaning, after the electrode plates 9 and 11 are cleaned, a timer is operated after a predetermined time has elapsed, and the valves 25 and 26 are automatically opened and the valve 27 is closed.
By controlling in this way, a convenient alkali ion water conditioner can be obtained. According to the alkali ion water purifier of the present invention, the drainage channel is connected to the suction port of the electrolytic cell via a valve, and the drainage pipe and the collection pipe are connected to each other via the valve. Therefore, for example, when it is desired to recover acidic ions, a large amount of energy is received per unit body by operating the valve.
Only the acidic ionized water that has been removed can be recovered. Thereby, the alkaline ionized water is mixed with the acidic ionized water to be recovered and neutralized, and the expensive recovered water is not made worthless. Further, when the electrode is washed, the washing water is not mixed into the water to be collected, so that the water quality is not impaired. And it is possible to secure recovered water having a stable pH.
