Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for ionizing water to separate it into alkaline ionized water and acidic ionized water.

[0002]

2. Description of the Related Art Water can be separated into alkaline ionic water and acidic ionic water by ionization. Alkaline ionized water exhibits excellent solubilizing power and penetrating power, in addition to the swelling action that softens the product. In addition, alkaline ionized water obtained by ionizing tap water has a feature that the content of chlorine can be extremely reduced. Acidic ionized water has excellent properties for cleaning, sterilizing and bleaching. Utilizing these effects, alkaline ionized water is used for drinking water, water for water splitting, water for coffee and tea. Further, acidic ionized water is used as boiling water for noodles, boiling water for beans, washing water for fruits and vegetables, boiling water for eggs, cleaning water, and the like. The alkaline ionized water and the acidic ionized water are obtained by electrolyzing water. When positive and negative electrode plates are provided facing each other in the water flow path, alkaline ionized water gathers near the negative electrode and acidic ionized water gathers near the positive electrode. The alkaline ionized water that collects on the negative electrode contains a positive electrolyte. The acidic ionized water that collects on the positive electrode contains a negative electrolyte. Water has calcium ion, sodium ion, magnesium ion,
It contains positive electrolytes such as potassium ions, and negative ions such as chlorine, sulfur, or silicic acid.

FIG. 1 schematically shows an electrode plate of a conventional device for ionizing water. In this electrode plate 1, a separator unit 2 is arranged between + and-electrode plates 1. The separator unit 2 is an ion-permeable diaphragm 2A that prevents the ionized water from mixing with the alkaline ionized water and the acidic ionized water. Therefore, the separator unit 2
Is a diaphragm 2 with fine voids through which water cannot pass freely.
A is used.

In the electrode plate 1 of this structure, water is introduced between the electrode plate 1 and the separator unit 2 to apply a DC voltage to the + and-electrodes. The inflowing water has a high + ion concentration in the vicinity of the-electrode plate 1 to become alkaline ionized water, and has a high-ion concentration in the vicinity of the + electrode plate 1 to become acidic ionized water. As described above, the device having the counter electrodes can reduce the electric resistance between the electrodes. This is because the facing area of the electrode plate 1 can be increased and the distance between the electrodes can be shortened. The resistance between the electrodes decreases when the facing area of the electrode plate 1 is increased and the electrode interval is reduced.
Therefore, this electrode structure has a feature that water can be efficiently ionized by a low voltage direct current.

[0005]

However, the electrode of this structure has a drawback that it is difficult to allow water to uniformly flow between the positive and negative electrode plates. For example, as shown in Figure 1,
If the supply port 3 is provided in the central portion, a large amount of water will flow into the center of the electrode plate 1, and the amount of water will decrease in both side portions. If the water cannot flow in uniformly, scale and the like will accumulate in the slow water flow area. The deposited scale locally discharges between the electrodes by significantly narrowing the + -electrode spacing. When water discharges between the electrodes, the discharged water becomes odorous. When the scale is further deposited, the +-electrode is short-circuited. The electrode short circuit causes an overload of the power supply and causes a failure. Also,
The voltage between the electrodes is lowered so that water cannot be efficiently ionized. Further, there is a drawback that a large current flows in the portion where the electrodes are short-circuited and the temperature locally rises.

The present invention was developed for the purpose of solving this drawback. An important object of the present invention is to allow water to flow in uniformly and effectively prevent the occurrence of scale,
Another object of the present invention is to provide an electrolytic ionized water generator capable of efficiently ionizing water while keeping the distance between the electrode plates constant.

[0007]

The electrolytic ionized water producing apparatus of the present invention has the following constitution in order to achieve the above-mentioned object. The apparatus of the present invention is characterized by having an electrolytic cell for passing water to ionize water into alkaline ionized water and acidic ionized water, and has all the configurations of (a) to (d) below. (A) In the electrolytic cell 4, a separator unit 2 that is ion-permeable and separates alkaline ionized water and acidic ionized water is provided between + and-electrode plates 1 that are arranged to face each other. There is. (B) In the separator unit 2, a diaphragm 2B made of plastic is insert-molded with a diaphragm 2A having ion permeability. In other words, the diaphragm 2A is inserted when the shape retaining frame 2B is molded from plastic. (C) The electrode plate 1 is superposed on the shape-retaining frame 2B of the separator unit 2, and a water inlet 5 is provided between the diaphragm 2A and the electrode plate 1. (D) The shape-retaining frame 2B of the separator unit 2 is provided between the diaphragm 2A of the separator unit 2 and the electrode plate 1 and has a branching protrusion 2C that divides the inflow port 5 into a plurality of flow paths. The branching ridge 2C disperses the inflowing water into a plurality of pieces and causes the water to flow between the electrode plates 1.

[0008]

In the electrolytic ionized water generator of the present invention, as shown in FIG. 2, the separator unit 2 is manufactured by inserting the diaphragm 2A into the shape retaining frame 2B. The separator unit 2 has a branching protrusion 2C. The branching protrusion 2C divides the inlet 5 provided between the diaphragm 2A of the separator unit 2 and the electrode plate 1. The inflow port 5 divided by the branching ridges 2C disperses the water flowing between the separator unit 2 and the electrode plate 1 and allows the water to flow in uniformly. The water that is dispersed and flows in uniformly flows over the entire surface of the electrode plate. Therefore, the device of the present invention can prevent the generation of scale that can be formed in a portion where water does not flow.

The electrolytic ionized water producing apparatus of the present invention has a unique structure of the separator unit incorporated in the electrolytic cell to prevent the scale of the electrode plate. The separator unit is manufactured by inserting a diaphragm into a plastic shape retention frame. In the separator unit manufactured in this way, the shape retaining frame is provided with the flow diverging protrusions. The flow divergence is located between the diaphragm of the separator unit and the electrode plate, and divides the inflow port between the diaphragm and the electrode plate into a plurality of parts. The inflow port, which is divided into a plurality of parts by the flow divergence, disperses the inflowing water and causes it to flow between the electrode plate and the diaphragm. The water that flows in in this state spreads over the entire surface of the electrode plate and prevents stagnation between the electrode plate and the diaphragm. Therefore, the electrolytic ionized water generator of the present invention prevents stagnation on a part of the electrode plate and prevents scale accumulation. Therefore, the malodor of water due to scale, local heating of the electrolytic cell,
