On the mounting plate 5, a pack of calcium hydroxide powder C packed in a water-permeable bag 6 is mounted.
Here, it is important to use only calcium hydroxide powder C as a raw material for the alkaline aqueous solution. That is, when calcium oxide (CaO) or the like is used, as described above, when an alkaline aqueous solution is generated, extremely high heat is generated, and there is a risk of the solution expanding or burning combustible materials. It may be inflamed or difficult to breathe, so it is very important to use calcium hydroxide powder C without calcium oxide (CaO), etc., and pack it so that this powder does not diffuse. It is.

A plurality of water passage holes 321 are also provided in the bottom portion 32 of the cassette portion 3, and the water A introduced into the inner peripheral wall portion 23 of the main body 2 rises through the water passage holes 321 of the bottom portion 32.

Although the water passage hole 321 is also opened in the vertical direction in the figure, the hole axis may have an angle in the vertical direction, like the water passage hole 55 of the mounting plate 5.

The configuration of the mounting plate 5, the holding plate 7, and the locking portions 332, 333, and 334 will be described with reference to FIG.
As shown in FIG. 2 (a), a notch 56 is provided in a part of the outer periphery of the mounting plate 5, and a convex locking part having a shape that passes through the notch 56 in a part of the inner peripheral wall 331. In order to fit the mounting plate 5, the notch portion 56 passes through the locking portion 332 and moves downward, and then rotates to lock the locking plate 333 below the locking portion 333. . In the case of the presser plate 7, the locking portion 333 is rotated to pass through a notch (not shown, but the same type as the notch 56), and is rotated and placed on the locking portion 334.
In order to set the filter 8, first, the presser plate 7 is passed through the locking portions 332 and 333 and then placed in the space between the upper surface of the locking portion 334 and the lower surface of the locking portion 333, or is held and pinched.

Here, a method of mounting the cassette unit 3 on the main body 2 will be described. The cassette unit 3 is housed in the outer case 21 and clamped so as to be pressed by the main body lid unit 24 from above. explain.
The front end portion 371 of the gap forming fitting ring 37 provided on the bottom portion 32 of the cassette portion 3 is fitted into the fitting ring-shaped groove 27 of the inner bottom portion 22 of the outer case 21, and the upper surface of the cassette lid portion 34 above the cassette portion 3. An annular convex portion 26 provided on the bottom surface of the main body lid portion 24 is fitted to the annular concave portion 343 of the main body lid portion 24 via a waterproof O-ring 344, and the main body lid portion 24 is screwed to sandwich the cassette portion 3 for attachment. On the contrary, in order to remove the cassette part 3, if the main body cover part 24 is removed, the cassette part 3 can be easily removed naturally. As described above, one of the features of the present invention is that the entire cassette unit 3 can be easily detached from the main body 2. Thus, the water poured from the inlet 282 does not enter the inside of the cassette unit 3 and the generated alkaline aqueous solution B is not diluted.

[PH adjustment unit 4]
Next, the PH adjustment unit 4 will be described. The PH adjustment unit 4 is connected to the discharge ports 283 and 284 of the main body lid unit 24 via the connection member 28.
The PH adjusting unit 4 adjusts and supplies a predetermined pH by adding water A such as separate tap water to the generated alkaline aqueous solution. The water supply passage 41 and the discharge port connected to the discharge port 283 are provided. An alkaline aqueous solution supply passage 42 connected to the H.284 is provided, an adjustment plug 44 is provided in the water supply passage 41, an adjustment plug 43 is provided in the alkaline aqueous solution supply passage 42, and both supply passages 41, 42 are provided downstream thereof.

Since it is the above structure, the process produced | generated from the water to alkaline aqueous solution is demonstrated in order.
[Flow of generated water from water (tap water, tap water, purified water) (removed generated water from the introduction)]
Water A such as tap water poured from the introduction port 282 passes through the water passage corridor D formed by the inner peripheral wall portion 23 of the outer case 21 and the outer peripheral wall portion 336 of the cylindrical portion 33 of the cassette portion 3. It reaches the bottom 32. A mounting plate 51 provided with a lower filter 81 and a water passage hole 55 in the cassette portion 3 from a water passage hole 321 opened to the bottom portion 32 of the cassette portion 3 (not to the bottom portion 32 but may be a lower portion of the side surface near the bottom portion). And enters the generation chamber X.
The water flow holes 55 of the mounting plate 5 are inclined in the vertical direction or along the circumference, and turbulence occurs when water passes through the holes (in the figure, the angles of inclination are the same). However, the angle of each hole may be different.) The reaction of the calcium hydroxide powder C in the generation chamber X and the inflowing water is promoted, and the alkaline aqueous solution of the aqueous calcium hydroxide solution is alkaline. B1 is generated.

The produced alkaline aqueous solution B1 of calcium hydroxide flows into the production chamber Y through the filter 82) sandwiched between the mounting plate 52 and the holding plate 72. The water passage holes 55 and 75 of the mounting plate 52 and the holding plate 72 are also at an angle in the vertical direction (circumferential direction), and the calcium hydroxide aqueous solution B1 is newly added to the new generation chamber Y by turbulent flow. It reacts with the calcium hydroxide powder C to form a higher concentration or saturated alkaline aqueous solution B2. Further, the generated calcium hydroxide aqueous solution B2 flows into the generation chamber Z through the filter 83) sandwiched between the mounting plate 53 and the holding plate 73.
In the generation chamber Z, like the generation chambers X and Y, the water flow holes 55 and 75 of the mounting plate 53 and the holding plate 73 have an angle in the vertical direction (circumferential direction), and turbulent hydroxylation The aqueous calcium solution B2 reacts with the new calcium hydroxide powder C in the generation chamber Z, and a saturated alkaline aqueous solution B3 is generated. This alkaline (saturated) aqueous solution B3 passes through the filter 84 sandwiched between the mounting plate 54 and the holding plate 74 and is pushed out from the opening 342 to the discharge port 284.

Here, since the calcium hydroxide powder C, which is a raw material in each of the production chambers X, Y, and Z, is in the water filled in the cassette unit 3, it reacts with carbon dioxide in the atmosphere and returns to calcium carbonate. There is nothing. This alkaline (saturated) aqueous solution and the accompanying water A have respective adjustment plugs 43 and 44, the water amount is adjusted by the respective adjustment plugs 43 and 44, and a desired PH value is determined based on the detected value of the PH meter. The adjusted alkaline (saturated) aqueous solution B4 is supplied to the necessary portion from the hose 286.
Since the present embodiment is configured as described above, the PH adjustment unit automatically sets the alkaline aqueous solution adjustment plug and the water supply adjustment plug to PH automatically by an automatic control device (not shown) according to the detected value of the PH meter. A configuration may be used in which the value is adjusted to be supplied.

According to this example, since only calcium hydroxide powder C is used as a raw material, the handling safety is high, and it does not directly touch or scatter and does not pollute the surrounding air environment. It is approved as a food additive, has very little effect on the human body, and does not generate high heat or generate toxic gases when dissolved or reacted in water when producing an alkaline aqueous solution.
In addition, since the cassette portion for storing calcium hydroxide powder is detachable with respect to the main body 2 and a plurality of mounting plates having a plurality of water passage holes are detachably provided therein, it is alkaline in use. (Saturated) When the residual powder in the cassette unit 3 which is the exchange cassette unit 3 for producing the aqueous solution becomes small, the cassette unit 3 containing only the calcium hydroxide powder C is continuously replaced. Can be generated. Moreover, the cleaning in the main body 2 and the outer case 21 and the cleaning in the cassette unit 3 are easy to remove each component, and can be cleaned safely and easily.
Further, since the cassette unit 5 is detachable by being sandwiched from above and below by the main body lid unit 24 and the inner bottom unit 22 of the outer case 21, it can be replaced very easily.

In addition, although the cassette portion for storing calcium hydroxide powder is detachable from the main body, a plurality of mounting plates having a plurality of internal water passage holes are also provided in a detachable manner. Calcium hydroxide can be replaced.
In addition, the bag portion 6 and the filter 8 packed with calcium hydroxide powder C inside the cassette portion 3 can be replaced by the locking mechanism of the mounting plate 5 and the presser plate 7, and the cassette portion 3 can be recycled. it can.
Furthermore, the amount of calcium hydroxide powder C to be consumed can be estimated from the saturation rate of the powder with respect to water and the amount produced, and since the produced alkaline (saturated) aqueous solution B3 has a very high alkalinity, it is used. It can be used after diluting to a PH value suitable for the purpose.
The generated alkaline (saturated) aqueous solution is water with a combined function of antibacterial ability, deodorizing ability, and cleaning ability, and is widely used in agriculture, fisheries industry, industry, service industry, school, hospital, welfare facility, general household, etc. it can.

In the examples of the present invention, it is important to use only calcium hydroxide powder C. When calcium oxide (CaO) or the like is used, extremely high heat is generated during the formation of the alkaline aqueous solution, There is a danger of inflating or burning combustibles, and if it comes in contact with the human body, it may cause irritation or difficulty in breathing. Therefore, use only calcium hydroxide powder C to eliminate calcium oxide (CaO), etc. Moreover, it is extremely important to pack the powder so that the powder does not diffuse.
Needless to say, the present invention is not limited to the above-described embodiments as long as the features of the present invention are not impaired.
