DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 FIG. Hereinafter, the sterilized ice according to the first embodiment of the present invention will be described. FIG. 1 is a central sectional view showing the sterilized ice according to the first embodiment. In FIG. 1, 1
Reference numeral 0 denotes a substantially dice-shaped sterilized ice according to the first embodiment, 1 denotes a substantially spherical central portion in the sterilized ice 10, and 2 denotes the sterilized ice 1.
0 is an outer peripheral portion that covers the periphery of the central portion 1. The central portion 1 contains a predetermined amount of hypochlorous acid generated by mixing chlorine and a pH adjuster with water,
The water containing hypochlorous acid, chlorine and a pH adjuster is frozen. Further, the outer peripheral portion 2 is frozen with water.

In the first embodiment, the boundary between the central portion 1 and the outer peripheral portion 2 is not actually clear. In the vicinity of the boundary, the concentrations of hypochlorous acid, chlorine, and the pH adjuster in the central portion 1 gradually decrease from the central portion 1 toward the outer peripheral portion 2. Therefore, in the first embodiment, the central portion 1 and the outer peripheral portion 2 are distinguished for convenience. However, except for the vicinity of the boundary, water containing hypochlorous acid is frozen in the central portion 1, and fresh water containing no impurities such as hypochlorous acid is contained in the peripheral portion 2. It is frozen.

Next, a method for producing sterilized ice according to the first embodiment will be described with reference to FIG. In FIG. 2, reference numeral 11 denotes a water supply pipe for water supply, and 12 denotes a magnetized water production device provided in the middle of the water supply pipe 11 and having a substantially cylindrical appearance. The magnetized water production device 1
2 includes two permanent magnets 13 and 14 facing each other.
Is provided. As shown in the figure, the permanent magnets 13 and 14 are opposed to each other so that their magnetic poles are opposite to each other.
It is attracted to magnetic poles of opposite polarities and extends longer toward the center of the magnetized water producing device 12.

The portion 11a of the water supply pipe 11 arranged in the magnetized water producing device 12 is wound in a substantially coil shape as shown in the drawing, so that the substantially coiled portion 11a is formed.
The tap water flowing through the portion a receives the force from the magnetic field lines for a relatively long time while flowing through the portion 11a. As a result, the tap water flowing through the water supply pipe 11 is magnetized to have various effects such as the cluster being decomposed into small pieces in the process of flowing through the substantially coiled portion 11a and the water permeability to bacteria and the like being improved. Transformed into water. The magnetized water produced by the magnetized water producing device 12 is discharged from the water supply port 11b of the water supply pipe 11 to the outside.

In FIG. 2, 15 is a plastic container containing, for example, 10 liters of tap water, and 16 is a plastic container containing, for example, 8 cc of sodium hypochlorite (a solution of chlorine having a concentration of about 12%). , 17 are, for example, 15 cc of a pH adjuster (the tap water is pH 3.5, for example)
For activating the chlorine by acidification to ~ 6.7 to facilitate the production of hypochlorous acid. For example, a plastic container containing a solution of hydrochloric acid). The water supply port 11b of the magnetized water is provided above the container 15, and tap water (magnetized water) from the water supply port 11b is discharged into the container 15 by, for example, 10 liters.

In this way, for example, 1
When 0 liter of magnetized water is filled, next, for example, 8 cc of sodium hypochlorite from the container 16 and 15 cc of the pH adjuster from the container 17 are added to the container 15. And agitate and mix (this produces a predetermined amount of hypochlorous acid having a bactericidal effect in the magnetized water).

Next, the mixed solution is used as an ice tray 18 for producing a plurality of relatively small dice-shaped ice as shown in the lower part of FIG.
(A plurality of partition plates 18a are arranged in the vertical direction and the horizontal direction, respectively). And this ice tray 1
8 is put in a freezer compartment, and the above-mentioned mixed solution is frozen while being stopped by cold air sent from a cool air supply section of the freezer compartment. In the freezing process in the freezer, the partition plate 1
8a, the solution in each section partitioned by the cold air freezes sequentially from the outer portion thereof by the cold air. At this time, the impurities such as the hypochlorous acid, chlorine, and the pH adjuster are removed. While frozen (ie, moving the impurities towards the center), they freeze as pure fresh water. Thereafter, a relatively high concentration of hypochlorous acid, chlorine and a pH adjuster are left in the central portion where the freeze is delayed most, and the solution containing these is frozen in a substantially spherical shape. This substantially spherically frozen portion (the portion composed of hypochlorous acid, chlorine, and water containing a predetermined amount of a pH adjuster) is the central portion 1 in FIG. Peripheral part 2.

Next, the method of use and operation of the sterilized ice thus manufactured will be described with reference to FIG. In FIG. 3, reference numeral 10 denotes a plurality of sterilized ices manufactured by the method described with reference to FIG. 2, reference numeral 21 denotes a vinyl bag for storing the plurality of sterilized ices 10, and reference numeral 22 denotes an opening of the bag 21. It is a fastening part to keep.

In the first embodiment, the bag 21 is used, for example, for washing medical equipment in medical institutions, washing dishes, for portable coolers of anglers, putting it into a fish cage in a restaurant, and storing fish caught by a fishing boat. It is manufactured in such a size that a required amount of sterilized ice can be stored for each use, such as for putting into a storage box. Also,
In the first embodiment, the bag 21 is formed of a black light-shielding material (the reason will be described later).

Now, an employee in a medical institution is required to
The operation when trying to wash the dishes of a large number of patients using the sterilized ice stored in the container will be described. The bag 21 containing the germicidal ice for dishwashing is, for example, required every month (for example, 9 times in the case of 30 times a day for 30 days).
It is assumed that only (0 bags) are delivered from a specialized trader to a medical institution and stored in a freezer in the medical institution.

In general, when chlorine and a pH adjuster are mixed in water, a predetermined amount of hypochlorous acid is produced and becomes sterilized water, but the sterilizing effect lasts for a relatively short period of about one week. Stop at. This is because the hypochlorous acid having the bactericidal effect is chemically decomposed by light (ultraviolet rays) or heat from the outside.
It is also decomposed by contact with organic matter).

On the other hand, as in the first embodiment, chlorine and a pH adjuster are added to the substantially spherical central portion 1 (see FIG. 1).
(Therefore, the hypochlorous acid generated by the chlorine, the pH adjuster and the water is confined in the central part 1), and frozen together with the peripheral part 2 (see FIG. 1) around the central part. In this case, no external heat is given to the hypochlorous acid, so that the hypochlorous acid present in the central portion 1 is not decomposed and maintains its sterilizing effect for a long time. Further, in the first embodiment, as shown in FIG. 3, since the plurality of sterilized ices are stored in a black and light-shielding bag 21, the central portion 1 is exposed to external light (ultraviolet rays). It is also prevented that the hypochlorous acid in the inside is decomposed, and also from this point, the hypochlorous acid existing in the central part 1 maintains its sterilizing effect for a long time without being decomposed. It is supposed to.

An employee of a medical institution trying to wash dishes removes the bag 21 delivered from the specialized company and stored in the freezer as described above, and puts the sterilized ice in the bag 21 into the container. Thaw it and put it in (thawing here may be natural thawing, or it may be thawed by applying heat from the outside). In this way, the worker can make sterilized water necessary for washing dishes only by performing a simple operation of removing the sterilized ice from the freezer and allowing it to thaw. Therefore, in the first embodiment, since a high-concentration chlorine solution, which is difficult to handle unless it is a specialized person, is not used as in the prior art, even an unskilled worker can easily produce sterilized water and use it for dishes and the like. Can be cleaned.

In the first embodiment, a black and light-shielding vinyl bag 21 is used as a container for storing a predetermined amount of the plurality of sterilized ices 10 in advance.
However, the present invention is not limited to this. For example, a container having a substantially rectangular parallelepiped shape or a substantially cylindrical shape formed of a black, light-shielding plastic hard material may be used. You may.

Embodiment 2 FIG. FIG. 4 is a central cross-sectional view of sterilized ice for describing Embodiment 2 of the present invention. In FIG. 4, reference numeral 30 denotes a substantially cubic sterilized ice according to the second embodiment. In the sterilized ice 30 of the second embodiment, impurities such as hypochlorous acid are almost uniformly mixed and dispersed throughout.

As a method of manufacturing the sterilized ice 30 of the second embodiment, for example, in FIG.
After sodium hypochlorite in the container 16 and the pH adjuster in the container 17 are mixed to generate hypochlorous acid, water containing the hypochlorous acid, chlorine, and the pH adjuster is rod-shaped. It can be manufactured by freezing while stirring with a thing.

Further, the sterilized ice 30 of the second embodiment is similar to that of FIG.
In, the water in the container 15, after which said the sodium hypochlorite in the container 16 is mixed with a pH adjusting agent in the vessel 17 to produce a hypochlorous acid, Ya the hypochlorite Water containing chlorine or a pH adjuster is continuously atomized by a sprayer into fine particles and sprayed into a space, so that the sprayed fine particles fall to a predetermined place, and the fine particles falling to the predetermined place are continuously scattered. It can be similarly manufactured by freezing.

The second embodiment differs from the first embodiment in that hypochlorous acid is concentrated in the central portion 1 in that hypochlorous acid is substantially uniformly dispersed throughout the ice. Has a different configuration. However, also in the second embodiment, since the water containing hypochlorous acid is frozen, heat from the outside is not conducted to the hypochlorous acid as in the first embodiment. Further, if the sterilized ice of the second embodiment is placed in a light-shielding container as shown in FIG. 3, hypochlorous acid in the sterilized ice may be decomposed by external light.
Can be prevented. Therefore, also in the second embodiment, the same operation and effect as those of the first embodiment can be obtained.

[0031]

As described above, according to the sterilized ice of the present invention, sterilized water containing hypochlorous acid is frozen and stored, so that hypochlorous acid is decomposed by heat. That can be prevented for a long time, keeping the sterilizing effect of hypochlorous acid for a long time, when sterilizing water is needed, it can be thawed as needed and used as sterilizing water Become. Therefore, according to the present invention, various scenes such as cleaning of medical instruments and dishes in medical institutions, preservation of fish caught in fishing boats, preservation of fish in fish cages of restaurants, preservation of fish in anglers' portable coolers, etc. In use, even amateurs who are not used to handling chlorine can easily
Sterilized water can be made and used at the work site.

Further, in the present invention, a center portion formed by freezing water containing hypochlorous acid, chlorine and a pH adjuster, and fresh water containing no impurities such as hypochlorous acid, chlorine and a pH adjuster are frozen. When the sterilized ice is constituted by the peripheral portion formed as described above, the conduction of external heat to hypochlorous acid in the central portion is more reliably prevented by the ice composed of fresh water in the peripheral portion, It is possible to more reliably maintain the hypochlorous acid for a long period of time. In particular, when the sterilized ice is composed of the central part and the peripheral part, even when the sterilized ice is put into a fish cage or a fish storage box, the sterilizing action does not work immediately but the sterilized ice is sterilized after a predetermined time when the peripheral part is thawed. It is possible to provide a predetermined time difference between the input of the sterilizing ice and the start of the sterilizing action, such that the action is performed.

In the present invention, as the water constituting the germicidal ice, magnetized water is used in which the tap water passes through an “artificially formed magnetic field” so that the cluster of the tap water is decomposed into small pieces. When doing so, since the magnetized water has a strong penetrating power to bacteria, etc., the sterilizing water obtained by thawing the germicidal ice has a bactericidal power to bacteria (hypochlorous acid penetrates to bacteria, etc.). Can be stronger.

In the present invention, when the sterilized ice is stored in a light-shielding storage device, not only is it possible to prevent the decomposition of hypochlorous acid in the sterilized ice due to heat, but also to prevent the sterilized ice from being sterilized. Since the decomposition of hypochlorous acid in ice due to light can be reliably prevented, it is possible to more reliably maintain the sterilizing action of the sterilized ice for a long period of time.

In the present invention, a first container containing a predetermined amount of water, a second container containing a predetermined amount of sodium hypochlorite, and a second container containing a predetermined amount of a pH adjuster are provided. 3 is prepared, and the chlorine solution in the second container and the pH adjuster in the third container are put in the first container and mixed, and the mixture is frozen. As a result, since sterilized ice is manufactured, even a person who is not very familiar with handling chlorine can manufacture the sterilized ice of the present invention relatively easily.

In the present invention, when the mixture is frozen and the mixture is frozen in a stationary state, water containing hypochlorous acid, chlorine and a pH adjuster is frozen. Center and hypochlorous acid, chlorine or p
It is possible to manufacture a sterilized ice constituted by a peripheral portion formed by freezing fresh water containing no impurities such as an H adjuster.

In the present invention, when the mixture is frozen and the mixture is frozen while being stirred, sterilized ice having hypochlorous acid dispersed almost uniformly throughout the ice can be provided. become. Thus, when using sterilized ice in which hypochlorous acid is almost uniformly dispersed throughout the ice, for example, when this sterilized ice is put into a fish cage or a fish storage box, the process in which the sterilized ice gradually thaws And always,
Bactericidal action can be exerted uniformly.

Further, in the present invention, when the mixture is frozen, the mixture is continuously sprayed as fine particles, and after the spraying, the particles which are sequentially dropped to a predetermined place are frozen. Sterilized ice in which hypochlorous acid is uniformly dispersed throughout the whole. As described above, when using sterilized ice in which hypochlorous acid is almost uniformly dispersed throughout the ice, for example, when this sterilized ice is put into a fish cage or a fish storage box, a process in which the sterilized ice gradually thaws Thus, the germicidal action can always be exerted uniformly.
