Description

[Detailed description of the invention]

(Industrial Application Field) The present invention relates to a fluid sterilizer, and in particular, a permanent magnet whose surface is plated with metal.
Relating to a fluid sterilization device that is installed in a container through which fluid such as water is stored or passes through, and can almost eliminate germs contained in the fluid in the container through the action of magnetism and metal ions. It is. (Prior Art) Traditionally, tap water has been mixed with chemicals such as chlorine in order to maintain water quality standards stipulated by the Water Supply Act. For this reason, tap water has a chlorine odor and is not very tasty as drinking water. Therefore, in order to remove chlorine and other fine suspended substances and obtain delicious water, tap water has traditionally been filtered by passing it through a water purifier. but,
Water purifiers generally filter water with a filter containing granular activated carbon, activated carbon fibers, long fiber nonwoven fabric, etc. to remove chlorine and other substances, so bacteria are likely to grow inside this filter. That is, although the filter of a water purifier suitably adsorbs and removes chlorine and the like, when the flow of water is stopped, the filter becomes a breeding ground for bacteria.
For this reason, water obtained through a water purifier often contains more bacteria than the water quality standards mentioned above. On the other hand, the effects obtained by applying magnetism to fluids such as water are beginning to be elucidated. In other words, it reduces germs (sterilization effect), almost eliminates limescale and scale from aquariums, piping, etc., and if cut flowers are placed in magnetic water (magnetized water or magnetic water), The cut flowers last a long time, the magnetized water has a mellow taste, and it promotes plant growth. Therefore, the present applicant previously focused on the above-mentioned sterilization effect and proposed a "fluid sterilization device" for the purpose of reducing bacteria in drinking water (Utility Application No. 110506/1986). (Problems to be Solved by the Invention) The above-described conventional techniques had the following problems. According to the method proposed in Utility Model Application No. 60-110506, a sterilization effect that could not be obtained with conventional water purifiers using filters can of course be obtained. However, in fluids such as water of poor water quality and containing a large number of germs, the sterilization effect is not sufficient, and there have been cases where it has not been possible to reduce the number of germs to almost zero. Therefore, there has been a desire for a fluid sterilization device that can reduce the number of germs to almost zero. The present invention has been made to solve the above-mentioned problems, or in other words, to realize the above-mentioned demands. (Means and actions for solving the problem) In other words, in order to solve the above problem,
In order to realize the above-mentioned desire, the present invention proposes that when metal ions are applied to a fluid such as water along with magnetism,
It has been experimentally confirmed that it has the effect of almost eliminating harmful bacteria such as E. coli contained in the liquid, and based on this, permanent magnets with metal plating on the surface are used to store fluids such as water. Alternatively, the first feature is that it is disposed inside a container through which it passes. In addition, in order to sufficiently remove chlorine, etc. and other fine floating substances mixed in fluids such as tap water at the same time as sterilization, the present invention also uses a container in which the fluid passes through a permanent magnet whose surface is plated with metal. The second feature is that a filter for filtering water is also provided at the same time. (Example) The present invention will be described in detail below with reference to the drawings. FIG. 1 is a sectional view of an embodiment of the present invention. 2 and 3 are plan views of the aperture plate magnet 5 and the diffusion plate 6, respectively, whose surfaces are metal-plated and which are housed in the case body 3 of FIG. 1. In FIG. 1, the case body 3 is a hollow bottomed cylindrical body made of non-magnetic material, and a water conduit portion 4 is provided protruding from the center of the bottom thereof. Further, a lid body 1 is fixed to the open end side of the case body 3 of the sterilizer of this embodiment with a fixing screw 8, and a water conduit part 2 is attached to the center part of the lid body 1.
is formed. Inside the cylindrical body of the case body 3, there are two diffusion plates 6a, 6b and three aperture plate magnets 5a to 5c.
are arranged alternately as shown in the figure. In addition, magnets 5b and 5c and diffusion plates 6a and 6 excluding magnet 5a are also included.
b has protrusions 5p and 6P on one surface thereof for forming voids 11c to 11f. In addition,
The aperture plate magnet 5a has air gaps 11a, 11 on both sides thereof.
It has protrusions 5Q and 5R for forming b. In this embodiment, the aperture plate magnet 5 having a focusing hole 9 in the center is made of a permanent magnet made of anisotropic ferrite or rare earth, and the strength of the magnetic field at the center of the focusing hole 9 is 1000 Gauss or more. It is becoming. Furthermore, the metal plating on the surface of the aperture plate magnet 5 is as follows:
Nickel (Ni) - Chromium (Cr) alloy, Nickel -
It is made of gold (Au) alloy or nickel-silver (Ag) alloy. The diffusion plate 6 is made of polypropylene, for example, and has a plurality of (12 in FIG. 3) diffusion holes 10 near its outer periphery.
is provided. When tap water, for example, is supplied to the water conduit section 2 in FIG. The portion 11b is filled with the liquid. The void 11
The water filling the space b is diffused by the diffusion holes 10 formed in the diffusion plate 6a, and merges in the gap 11c. The water that has merged into the cavity 11c flows through the diaphragm plate magnet 5b.
It flows along the side surface on the N pole side, concentrates in the convergence hole 9, and flows out into the next gap 11d. Thereafter, as in the case of the diffusion plate 6a or the aperture plate magnet 5b, the diffusion plate 6b diffuses the air into the cavity 11.
After that, it flows along the N-pole side side of the diaphragm plate magnet 5c, and is discharged to the outside as shown by arrow B through the water conduit portion 4 while concentrating in the convergence hole 9. That is, the water supplied from the water conduit section 5 is squeezed by the diaphragm plate magnet 5, then diffused by the downstream diffusion plate 6, and further flows into the downstream cavity 11.
The metal plated aperture plate magnet 5 is repeatedly squeezed and diffused so as to merge at the
come into contact with As a result, the water is strongly influenced by magnetism and metal ions. As described above, when tap water is passed through the device of this embodiment, according to the experiments of the present inventor, especially the surface of each of the aperture plate magnets 5a and 5b on the water conduit section 2 side (N-pole side surface) Also, a large amount of water scale was observed near the contour surface of the convergence hole 9. In addition, when the present inventor conducted a water quality test by passing tap water that had been stored in a tank through the device of this embodiment, it was found that the water quality was significantly lower than that of the sterilization device of Utility Application No. 110506/1983. A decrease in bacteria such as E. coli was observed. In other words, even if tap water has a fairly large number of general bacteria before passing through the device of this embodiment, when water quality is tested through the device of this embodiment,
The presence of the bacteria could not be detected at all. Based on these facts, if a fluid such as water is linked to a magnetic flux and made to flow through metal ions at the same time, it is possible to significantly reduce the number of bacteria, although this cannot be fully explained theoretically. However, even if the quality of tap water is poor and the number of common bacteria is quite large, it can be said that it is effective in eliminating the bacteria. In the embodiment shown in FIG. 1, three aperture plate magnets 5a to 5c are arranged in combination with two diffusion plates 6a and 6b arranged between them, as metal-plated permanent magnets that have a sterilization effect. However, the present invention is not limited thereto. That is, the desired number of combinations (number of stages) may be selected depending on the water quality (number of germs), and it goes without saying that the sterilization effect improves as the number of combinations increases. Furthermore, the structure of the sterilizer is not limited to the one shown in Fig. 1, but the key point is that fluids such as water come into contact with the metal-plated permanent magnet surface as widely as possible, and for as long as possible. It only needs to be configured so that it interlinks with the magnetic flux and flows through the metal ions. FIG. 4 is a sectional view showing a second embodiment of the present invention. In the figure, the same reference numerals as in FIG. 1 represent the same or equivalent parts. The second embodiment is the embodiment shown in FIG.
The difference from the above embodiment is that a fluid filtration filter 7 containing granular activated carbon, activated carbon fiber, long fiber nonwoven fabric, etc. is used instead of the aperture plate magnet 5a.
This is the point where . Note that the filter 7 has protrusions 7 on both sides thereof for forming voids 11a and 11b.
a, 7b. As described in the "Prior Art" section, the filter 7 has the function of suitably adsorbing and removing chlorine, etc., and other fine floating substances contained in fluids such as tap water. However, on the other hand, when the flow of water is stopped, the moisture remaining in the filter 7 becomes a culture and bacteria propagate. However, as in the second embodiment, metal-plated magnets 5b, 5c and diffusion plates 6a, 6b
At the same time, by disposing the filter 7, the bacteria inside the case body 3 can be completely extinguished by the action of magnetism and metal plating while water is flowing. As a result, according to the second embodiment, the effect of the filter 7 makes it possible to obtain delicious water that does not have a limescale odor or the like and is free from germs. Furthermore, regarding FIG. 4, from the direction of arrow A to B
If a valve 12 is provided at the tip of the water conduit section 4, which opens when the water pressure exceeds the water pressure flow expected to flow in the direction and normally remains closed, the water supply from the direction of arrow A is stopped and the valve 12 opens when the water pressure flow is higher than that expected to flow in the direction. The valve 12 is closed, and the inside of the case body 3 becomes filled with water. This means that during the water supply stop time, the magnetism and metal ions sufficiently act on the residual water inside the case body 3, which particularly enhances the sterilization effect on the residual water inside the filter 7. Note that the filter 7 does not need to be provided immediately after the water supply port (water conduit section 2) as shown in FIG. 4, and may be provided, for example, at the position of the aperture plate magnet 5b. However, according to the inventor's experimental results, it was more effective to provide it in the front half of the case body 3 in the water flow direction. FIGS. 6 and 7 respectively show the above-mentioned
This is a modification corresponding to FIG. 2 and FIG. The embodiment of FIG. 6 (third embodiment) differs from FIG. 1 in that the aperture plate magnets 5a to 5c and the diffuser plate
a, 6b are made smaller in diameter to form a gap 30 between the outer peripheral surfaces of the magnets 5a to 5c and the diffusion plates 6a, 6b and the inner wall of the case body 3, and the projections 5Q,
6P and the protrusion 5P of the magnet 5c are each provided with a notch 31. In addition, in this example,
Even if the cavity 30 is formed, the magnets 5a~
5c and the diffusion plates 6a, 6b are provided with, for example, wart-like protrusions (not shown) at equal intervals, so that the magnets 5a to 5c and the diffusion plates 6
a and 6b do not shake inside the case body 3. In Figure 6, water supplied from the direction of arrow A is
Similar to FIG. 1, a metal-plated magnet 5a
Sterilized by the action of ~5c magnetism and metal ions. At the same time, a portion of the supplied water flows out into the gap 30 through the notches 31 and the like. The water flowing into the gap 30 flows along the outer magnetic pole surface of at least one of the magnets 5a to 5c. For this purpose, magnets 5a to 5
The outer magnetic surface of c also sterilizes the bacteria in the water. That is, according to this embodiment, the outer magnetic pole surface of each of the magnets 5a to 5c can be effectively used, and bacteria in the water can be efficiently sterilized. In addition, the water flowing into the gap 30 is removed by the magnet 5c.
Since the water flows into the gap 11f through the notch 31 formed in the protrusion 5P, it merges with the main water explained with reference to FIG. 1 and is discharged through the water conduit 4 in the direction of arrow B. Become. Furthermore, the embodiment shown in FIG. 7 (fourth embodiment) is the fourth embodiment.
The difference from the figure is that the diameters of the aperture plate magnets 5b, 5c and the diffusion plates 6a, 6b are made smaller, and the magnets 5b,
A gap 30 is formed between the outer peripheral surfaces of the magnet 5c and the diffusion plates 6a and 6b and the inner wall of the case body 3, and a notch 31 is provided in each of the protrusion 6P and the protrusion 5P of the magnet 5c. Incidentally, as in the case of FIG. 6, in this embodiment, evenly spaced wart-like convex portions (not shown) are provided on the outer peripheral surfaces of the magnets 5b, 5c and the diffusion plates 6a, 6b, so that the magnets 5b,
5c and the diffusion plates 6a and 6b do not wobble. The reason for providing the gap 30 and notch 31 in FIG. 7 is the same as that explained in FIG. 6 above. In addition, in the first to fourth embodiments described above, if the diffusion plate 6 is made of a permanent magnet whose surface is plated with metal, the fluid passing through each sterilizer will be more strongly magnetically and It will be affected by metal ions. As a result, it is easy to understand that the sterilization effect can be greatly enhanced. The sterilizers of the above first to fourth embodiments are as follows:
It was a so-called closed type device. However, depending on the application, the lid 1 may be omitted and the device may be used as a so-called open type device. Further, the case main body shape does not have to be cylindrical, and may be rectangular, for example. Furthermore, it goes without saying that the permanent magnets disposed inside do not need to be disk-shaped either. Further, the present invention provides a case main body 3 as described above.
The present invention is not limited to sterilizers in which a fluid such as water passes through the sterilizer. That is, for example, a metal-plated magnet may be placed inside a rectangular or cylindrical container, and a fluid such as water may be stored therein. Even in this case, it is possible to significantly reduce the amount of bacteria mixed in the fluid, and when ordinary tap water is stored, it is possible to almost completely eliminate the bacteria in the water. The following Table 1 shows the sterilization effect of E. coli in 1 ml of ring-shaped magnets with different surface plating states placed in a container containing 40 c.c. of water so that they are completely immersed in the water. These are the experimental results shown for each elapsed time. The ring-shaped magnet had an inner diameter of 30 mm, an outer diameter of 60 mm, and a thickness of 8 mm and was used so that the bottom of the magnet was floating.

[Table] From this experimental result, it will be understood that in the present invention, the sterilization effect is extremely effective when the magnet surface is coated with Ni-Au plating or Ni-Ag plating. In addition, when the present inventor places a cut flower in a vase in which a Ni-Ag-plated magnet is arranged in stored water, the cut flower is placed in a vase in which a similar unplated magnet is arranged. I would like to note that the flower's longevity was much better compared to the case. FIG. 5 is a sectional view showing an example of application of one embodiment of the present invention. In the figure, 20 is a water tank storing water 21 as shown in the figure, 22 is a container submerged in the water 21 in the tank, and 23 is a metal-plated surface arranged inside the container 22. The magnet 24 shown is a support member 24 that supports the magnet 23 so as to float above the bottom of the container 22. In addition, the above 22
24 constitute the sterilization apparatus of this embodiment. As shown in FIG. 5, when a sterilizer is placed in a water tank 20, germs contained in the water in the container 22 of the sterilizer are destroyed by the action of magnetism and metal ions. Therefore, for example, the water in the container 22 may be pumped up using a pipe or the like, or a water discharge pipe (not shown) may be installed by any known appropriate means so that the water in the container 22 can be discharged. Then, the water 21 in the water tank 20 can be taken out in a germ-free state. In the sterilizer of the present invention, as described above, water scale and the like adhere to the permanent magnet whose surface is plated with metal. If this exceeds a certain limit, the sterilization effect will decrease. In the present invention, in such a case, the magnet may be taken out, washed with water, or cleaned with cloth or paper, and then set to the state before being taken out. That is, the sterilizer of the present invention can be used for a long period of time by cleaning without replacing any of the parts with new ones. In the case of the embodiments shown in FIGS. 1, 4, 6, and 7, the fixing state by the fixing screws 8 is released, the lid body 1 is removed, and the aperture diaphragm housed in the case body 3 is removed. Plate magnet 5 and diffusion plate 6
etc. can be taken out. At this time, if adjacently arranged magnetic pole surfaces have opposite polarities and are attracted to each other, the magnet parts automatically become one mass, making handling convenient. This also applies when storing the magnet section. (Effects of the Invention) As is clear from the above description, according to the present invention, the following effects are achieved. (1) A permanent magnet with a metal-plated surface is placed inside a container through which a fluid such as water is stored or passes through, so even if the fluid contains a relatively large number of bacteria, These bacteria can be reduced to almost zero. This effect is extremely remarkable when compared with a sterilization device constructed of permanent magnets whose surfaces are not plated with metal. (2) In addition, if a permanent magnet with a metal-plated surface and a filter for filtering the fluid are installed in a container configured to allow the fluid to pass through, the Not only can the bacteria in the fluid be eliminated, but also chlorine and other fine floating substances contained in the fluid can be completely removed. As a result, according to the present invention, drinking water such as tap water can be provided in a germ-free and delicious manner.
