BACKGROUND OF THE INVENTION Field of the Invention The present invention generally relates to electrolytic ionized water generating apparatuses, and more particularly to electrolytic ionized water generating apparatuses which are improved so that scales such as calcium and magnesium do not adhere to the electrodes.

[Prior art]

FIG. 9 is a front view of a conventional electrolytic ion water generator, FIG. 10 is a side view thereof, FIG. 11 is a partial sectional view of the electrolytic ion water generator viewed from the front thereof, and FIG. 12 is a sectional view seen from the side of the conventional electrolytic ion water generator.

Referring to these drawings, a conventional electrolytic ion water generating device includes a main body 1. The main body 1 is for storing an electric circuit, an electrolytic cell, and a cartridge for water purification.

The head 2 of the main body 1 is attached with a replacement cap 2 for a water purification cartridge. The water purification cartridge 3 is a rectifier that inhales tap water and removes foreign substances or organic matter, rust, chlorine, and chlorcalc smells contained in the tap water. The electrolyzer 4 receives tap water that has passed through the cartridge 3 for water purification, and electrolyzes the tap water by applying a DC voltage to the electrodes 6 and 7. In the electrolytic cell 4, alkaline water and acidic water are produced. In the electrolytic cell 4, a diaphragm 5, a drinking alcohol 6, and an anode 7 are provided. The diaphragm 5 passes a cation and an anion, and isolates alkaline water and acidic water in the electrolytic cell 4. The cathode 6 is formed of, for example, a stainless plate. The anode 7 is formed of, for example, ferrite.

The power switch 8 is an on / off switch of a power supply, and is usually a push button type. The power lamp 9 is ignited during energization. The reset switch 10 is a reset of the cartridge replacement timer. The cartridge lamp 11 indicates when the cartridge is to be replaced. The clean water lamp 12 ignites at the time of electrolytic cell cleaning. The current indicating lamp 13 is used for displaying the electrolytic current. The PH regulator 14 adjusts the pH of the water to be produced. The printed board 15 is for attaching and wiring electrical circuit components. The power supply transformer 16 replaces commercial power with electrolytic power. The chassis 17 attaches each mechanism part. The intake port 18 is an outlet of an alkaline water. The absorption port 19 is for absorbing tap water. The drain port 20 is for taking out the acidic water and draining the residue. The power cord 21 feeds power to the main body from an AC power source.

Figure 13 is for illustrating the shape occurring in the electrolytic cell. Referring to FIG. 13, when a direct current voltage is applied to the negative electrode (alkali electrode) and the positive electrode (acidic electrode), positive ions, which are mineral nutrients such as calcium, magnesium, and potassium present in tap water, adhere to the negative electrode. Further, negative ions such as chlorine, sulfuric acid, and sulfur stick to the anode. At the same time, since the hydrogen ions H + take electrons from the cathode and become hydrogen molecules (H ₂ ) and fly away in the air, the hydroxyl ions (OH−) increase, and the water becomes alkaline. On the other hand, in the anode, since the hydroxyl ions (OH-) give electrons to the anode to form oxygen molecules (O ₂ ) and fly out into the air, the hydrogen ions (H +) increase, and the water becomes acidic. The reaction at the cathode and anode is expressed by the chemical equation as follows.

Cathode: 4H ⁺ + 4e → 2H ₂

Anode: 4OH- → O ₂ + 2H ₂ O + 4e

In this way, the water on the cathode side becomes alkaline drinking water containing a lot of mineral nutrients, and the water on the anode side is discarded.

[Problems to Solve Invention]

Since the conventional electrolytic ion water generator is configured in this manner, when used for a long time, scales such as calcium and magnesium adhere to the cathode, the electrolytic current decreases, and electrolysis may not be sufficiently performed.

In order to prevent this, conventionally, when the use time reaches a certain time, a method of manually or automatically inverting the voltage between the electrodes to remove the scale attached to the negative electrode and maintaining the original performance has been adopted.

However, in this conventional method, there have been many cases in which the scale separated from the cathode side (alkali electrode plate) during or after washing becomes a solid material and floats in alkaline water to be edible.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide an electrolytic ion water generating apparatus which is improved so that scales such as calcium and magnesium do not adhere to the electrodes.

[Means for solving the problem]

The present invention relates to an electrolytic ionized water generating apparatus for generating alkaline water and acidic water by applying a voltage between the first electrode and the second electrode separated by a diaphragm and electrolyzing tap water. The apparatus has an alkaline water outlet for taking out alkaline water and an acidic water outlet for discharging acidic water. The apparatus also includes a first electrode chamber comprising a first electrode and a second electrode chamber comprising a second electrode. A first water channel is provided between the alkali water outlet and the first electrode chamber to flow electrolytic water generated in the first electrode chamber toward the alkaline water outlet. A second water channel is provided between the acidic water outlet and the second electrode chamber to flow the electrolytic water generated in the second electrode chamber toward the acidic water outlet. A third channel is provided between the alkaline water outlet and the second electrode chamber, and is provided with a third channel for flowing electrolyzed water generated in the second electrode chamber toward the alkaline water outlet. A fourth water channel is provided between the acidic water outlet and the first electrode chamber so as to flow the electrolytic water generated in the first electrode chamber toward the acidic water outlet. The device has the third channel and the fourth channel closed when the first channel and the second channel are opened, while the third channel and the fourth channel are closed when the first channel and the second channel are closed. It is provided with a switching valve for switching the channel to open. The apparatus further includes control means for operating the switching valve when the supply voltage between the first electrode and the second electrode is inverted, whereby the alkaline water outlet is always taken out of the alkaline water outlet.

[Action]

According to the electrolytic ionized water device according to the present invention, when the supply voltage is inverted between the first electrode and the second electrode, the switching valve is operated so that the alkaline water is always taken out from the alkaline water outlet, thereby inverting the electrolytic voltage in a short cycle. In this case, the scale can be prevented from adhering to the electrode at all.

EXAMPLE

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In front of the electrolytic ion water generating device, a power indicator 51 that lights during energization is provided. The power switch 52 is an open / close switch of a power supply and is push button type. In front of the electrolytic ion water generating device, a water intake lamp 53, a water intake switch 54, a flow rate indicator 55, a PH range indicator 56, a PH range switch 57 and a cartridge replacement timing indicator 58 Is installed.

Referring to FIG. 2, the cartridge for water purification 59 is for removing chlorine and the like from tap water. The electrolytic cell 50 is for generating alkaline water and acidic water. The printed circuit board 61 is for attaching and wiring electrical circuit components. The diaphragm 62 in the electrolytic cell 60 passes through cation and anion to separate alkaline water and acidic water in the electrolytic cell 60. The electrode plate 63 serves as a pole for electrolyzing tap water. The power transformer 64 is for replacing commercial power with electrolytic power. The characteristic of this embodiment is that the cross line 66 described later is provided. The crossline drive motor 95 is connected to the crossline 66.

3 is a flowchart of the electrolytic ionized water generating device according to the embodiment. Tap water enters the cartridge 59 for water purification, where chlorine in the tap water is removed. Tap water is sent to the electrolyzer 60. The amount of tap water sent to the electrolyzer 60 is measured by the processor 81. In the electrolytic cell 66, tap water is electrolyzed, thereby generating alkaline water and acidic water. As will be described later, the alkaline water is always taken out at the outlet by the cross line 66, and the acidic portion is always drained at the outlet. The electrolytic cell 60 and the cross line 66 are connected to the control circuit 80. The control circuit 80 is connected to the processor 81. When the processor 81 detects that a certain amount of tap water has flowed down, a command is given to the control circuit 80, and the control circuit 80 receives the command and inverts the supply voltage to the electrolytic cell 60, and at the same time, the cross line ( The valve body of 66 is operated. In this way, the alkaline water is always withdrawn from the outlet, and the acidic portion is always discharged from the outlet. According to this apparatus, since the supply voltage can be reversed in a short cycle, no scale is attached to the electrode.

In addition, since all of the above operations are performed automatically inside the machine, the electrodes are cleaned without any user's attention, and no labor is required.

When alkaline water enters the inlet 1 and acidic water enters the inlet 2, the valve rotor is operated so that the alkaline water is taken out of the alkaline water outlet and the acidic water is discharged from the acidic water outlet.

The timing of reversing the supply voltage applied between the first electrode and the second electrode is determined by the amount of water entering the electrolytic cell of the tap water detected by the sensor 81. When a certain amount of tap water is supplied to the electrolytic cell, the sensor 81 instructs the microcomputer whose control circuit 81 is the control circuit 80, and the microcomputer controls the supply voltage applied between the first electrode and the second electrode. The valve rotor 88 is rotated by inverting and simultaneously driving the motor 95. Thereby, alkaline water is always taken out from an alkaline water outlet, and acidic water is always discharged from an acidic water outlet.
