Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for producing electrolytic ion water, and more particularly to an electrolytic ion water for converting raw water in an electrolytic cell into ion water by energizing electrodes arranged in the electrolytic cell. It relates to a generator.

[0002]

2. Description of the Related Art An example of an electrolytic ionized water producing device for converting raw water in an electrolytic cell into ionized water by energizing electrodes arranged in the electrolytic cell is disclosed in Japanese Patent Publication No. 60-20073. Technology is available. In this electrolytic ionized water generator, the electrolytic cell is partitioned by a porous partition wall to form a cathode chamber and an anode chamber. Electrodes are respectively arranged in these electrode chambers, and the raw water in the electrolytic cell is electrolyzed to form the anode chamber. Alkaline ionized water with a high pH value is generated. PH suitable for human body such as drinking
The value is 8.5 to 9.5, and if it is less than 8.5, it is not so different from the raw water, while if it exceeds 10.0, it is rather harmful. Therefore, in the conventional electrolytic ionized water generator,
A method is adopted in which a constant power corresponding to the electrolysis capacity such as the capacity of the electrolytic cell is supplied to the electrodes to adjust the pH value to 8.5 to 9.5.

[0003]

However, the above-mentioned conventional method of regulating the pH value within a predetermined range has the following problems. The amount of electric power supplied to the electrode for setting the pH value within the predetermined range is set to an amount of electric power suitable for setting the pH value within the predetermined range in a state where the electrolytic cell is filled with raw water. Therefore, when the amount of raw water introduced into the electrolytic cell is small and the same amount of electric power as that in the filled state is supplied to the electrode, the electrolytic capacity increases with respect to the amount of raw water, and the pH of the alkaline ionized water increases. There is a problem that the value exceeds 8.5 to 9.5 and becomes a value in a harmful range. Therefore, an object of the present invention is to provide an electrolyzed ionized water generator capable of keeping the pH value of ionized water within a predetermined range regardless of the amount of raw water introduced into the electrolytic cell.

[0004]

In order to solve the above problems, the present invention has the following constitution. That is, by energizing the electrodes arranged in the electrolytic cell, in the electrolytic ion water generator for converting the raw water in the electrolytic cell into ionized water, the flow rate or water pressure of the raw water introduced into the electrolytic cell is Detecting means for detecting, electric power adjusting means for adjusting the electric power supplied to the electrode, and in order to maintain the pH value of the ionized water within a predetermined range, based on the flow rate or the water pressure detected by the detecting means, And a control unit for adjusting the electric power supplied to the electrode via the electric power adjustment unit.

[0005]

[Operation] The operation will be described. The control means adjusts the electric power supplied to the electrodes through the electric power adjusting means based on the flow rate or the water pressure detected by the detecting means, thereby adjusting the pH value of the ionic water regardless of the amount of raw water introduced into the electrolytic cell. It can be maintained within a predetermined range.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 shows a schematic mechanical structure of this embodiment, and FIG. 2 shows an electric structure of a main part. In FIG. 1, 10 is a faucet, and raw water or alkaline ionized water is selected and discharged by a branch plug 12. Raw water or alkaline ionized water is selected from the handle 1 provided on the branch tap 12.
This can be done by rotating 4. When the raw water is selected, the raw water supplied from the water pipe (not shown) is directly discharged from the faucet 10. On the other hand, when the alkaline ionized water is selected, the raw water supplied from the water pipe (not shown) is the branch plug 1.
The alkaline ionized water that has flowed from 2 toward the pipe 16a and is electrolyzed and generated flows into the branch plug 12 from the pipe 16e and is discharged from the faucet 10. Reference numeral 18 denotes a water purification tank, into which raw water can flow in via a pipe 16a. The raw water that has flowed in passes through the activated carbon cartridge 20 and further passes through the hollow fiber membrane layer 22 to be purified. The purified raw water flows out from the pipe 16b.

Reference numeral 24 is a thermistor, which is provided to detect the temperature of the raw water flowing through the pipe 16a. This is provided to prevent the activated carbon in the activated carbon cartridge 20 from deteriorating when raw water having an abnormally high temperature flows into the water purification tank 18. For example, when the thermistor 24 detects that the temperature of the raw water exceeds 35 degrees, the first solenoid valve 2
6 blocks the pipe 16a. A first water pressure sensor 28 detects the water pressure of the raw water flowing through the pipe 16a. A second water pressure sensor 30 detects the water pressure of the raw water flowing through the pipe 16b, and also detects the water pressure of the purified raw water introduced into the electrolytic cell 32 as an example of the detection means. As the detecting means, a flow rate sensor may be used instead of the water pressure sensor. Further, by comparing the values detected by the first water pressure sensor 28 and the second water pressure sensor 30, it is possible to detect the degree of clogging of the water purification tank 18. In this case as well, a clogging of the water purification tank 18 can be detected by using a flow rate sensor in addition to the water pressure sensor.

Reference numeral 34 is a constant flow valve, which regulates the maximum value of the flow rate (or water pressure) of the purified raw water which flows through the pipe 16b and is introduced into the electrolytic cell 32. Reference numeral 36 is a calcium addition cylinder, which supplies a fixed amount of calcium powder to the purified raw water flowing through the pipe 16b. Electrodes 38 and 40 are arranged in the electrolytic cell 32 at intervals. 38 is an anode and 40 is a cathode. Pipe 16 in the electrolytic cell 32
Purified raw water is introduced from b. A DC voltage is supplied to the electrodes 38, 40 from a voltage adjusting circuit described later, and
The purified raw water inside is electrolyzed. By this electrolysis, alkaline ionized water containing OH ions is generated in the anode chamber 44 separated by the diaphragm 42, and acidic water is generated in the cathode chamber 46. The alkaline ionized water flows out of the electrolytic cell 32 via the pipe 16c. On the other hand, acid water is pipe 16
It flows out of the electrolytic cell 32 via d. In addition, pipe 1
The acidic water flowing out from 6d is used for drainage or other purposes. A second solenoid valve 48 opens and closes the pipe 16e branched from the pipe 16c.

Reference numeral 50 denotes a third solenoid valve, which is a pipe 16e.
The pipe 16c ahead of the branch point is opened and closed. Pipe 1
The tip of 6c merges with the pipe 16d. When the second solenoid valve 48 is opened and the third solenoid valve 50 is closed, the alkaline ionized water is absorbed by the pipe 16c and the pipe 16c.
If it is sent to the tap 10 via d, and the branch tap 12 selects alkaline ionized water, the alkaline ionized water flows into the branch tap 12 from the pipe 16e and is discharged from the tap 10. On the other hand, the second solenoid valve 48 is closed and the third solenoid valve 5
When 0 is open, the alkaline ionized water is pipe 16
It flows from c to the pipe 16d and is drained. For example, it is used in this mode when the residual water in the anode chamber 44 and the cathode chamber 46 is drained when it is reused after the use of the electrolytic ionized water generator is once stopped. It is also possible to make water in which alkaline ionized water and acidic water are mixed. At this time, the flow rate adjusting screw 52 provided in the middle of the pipe 16d can adjust the flow rate of the acidic water to adjust the mixing ratio of the alkaline ion water and the acidic water.

Next, the electric system will be described with reference to FIG. A voltage adjusting circuit 54 is an example of an electric power adjusting means, and applies a DC voltage between the anode 38 and the cathode 40.
The voltage adjusting circuit 54 adjusts the applied voltage according to an instruction from the microprocessor described later. The power adjusting means is not limited to voltage adjustment and may be current adjustment. Reference numeral 56 denotes a microprocessor (MPU) that is a control means, and the second water pressure sensor 30 is used to maintain the pH value of the alkaline ionized water within a predetermined range (pH 8.5 to 9.5 in this embodiment). The voltage applied to the anode 38 and the cathode 40 is adjusted via the voltage adjusting circuit 54 on the basis of the water pressure detected by. The relationship between the water pressure and the applied voltage is a relationship known in advance from experiments such as the capacity of the anode chamber 44 and the cathode chamber 46. In addition, the MPU 56 uses the water temperature value detected by the thermistor 24 to operate the first solenoid valve 26, the water pressure value detected by the first water pressure sensor 28, and the water pressure value detected by the second water pressure sensor 30. It determines the degree of clogging of 18 and controls operations such as opening and closing the second solenoid valve 48 and the third solenoid valve 50 according to a user's instruction or the like.

Reference numeral 58 denotes a RAM, which is the second water pressure sensor 3
Water pressure detected by 0, water temperature value detected by the thermistor 24,
The water pressure value detected by the first water pressure sensor 28, data such as the degree of clogging of the water purification tank 18, and user input are temporarily stored. Reference numeral 60 denotes a ROM, which is an operating system of the MPU 56, a control program for maintaining the pH value of the alkaline ionized water within a predetermined range, the alkaline ionized water p
In order to maintain the H value within a predetermined range, control data such as table data showing the relationship between the water pressure detected by the second water pressure sensor 30 and the applied voltage is stored in advance. With such a configuration, the MPU 56, which is the control unit, can operate the pipe 16
When the flow rate of the raw water flowing through b is small, the voltage applied to the anode 38 and the cathode 40 via the voltage adjusting circuit 54 is adjusted based on the water pressure detected by the second water pressure sensor 30 to adjust the pH value of the alkaline ionized water. Keep within a predetermined range. Pipe 1
When the flow rate of the raw water flowing through 6b increases and reaches the water pressure (flow rate) regulated by the metering valve 34, the metering valve 34 operates and the water pressure does not exceed it. Therefore, a constant voltage is maintained during the water pressure. Is applied to the cathode 40 to maintain the pH value of the alkaline ionized water within a predetermined range. Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. ..
