Needless to say, the form can be modified such as a structure in which one attracting electrode is attracted from both directions toward the center.

Although a combination of copper and zinc has been described as an electrode, a combination of metals having different oxidation-reduction voltages and capable of generating an effective voltage, if there is no problem in safety, is used. Is not limited.

0 again from the inlet 11 ′ provided on the side wall.
Circulates to

In the storage container 10, a table 20 with a removable handle for mooring the denture 19 is provided. The bottom of the table 20 is formed of a net-shaped bottom plate that can transmit microorganisms and ultrasonic waves for cleaning.

Although not shown, a circuit for supplying a weak voltage to the sterilization tank, a circuit for driving the ultrasonic vibrator, a circuit for intermittently operating the pump, and other operating conditions of the denture cleaning / storage device are not shown. Is provided to the user as appropriate.

First, the denture 19 is placed on the base 20 and the liquid 11
Is placed in a storage container 10 in which a predetermined amount is placed. Although the tap water is sufficient for the liquid 11, tap water may be used to dissolve an agent effective for separating and dispersing microorganisms such as fragrances, pigments, and surfactants from the dentures.

By the operation of the electronic circuit, the ultrasonic vibrator 12 is operated for a certain period of time, and contaminants including microorganisms adhering to the surface of the denture 10 are separated and dispersed in the liquid 11.

Next, the pump 18 is operated to start sending the liquid 11 in the storage container 10 to the sterilization tank 15. After being physically disinfected in the disinfection tank 15 by the operation described below, it is circulated again to the storage container 10.

According to this principle, the microorganisms separated from the dentures are accumulated in an inactivated state on the surface of the upper electrode, and the dentures are stored hygienically with the microorganisms removed.

During the operation of the disinfection tank, the disinfection tank 15 can be taken out of the storage container 10 together with the inactivated microorganisms and used continuously.

Hereinafter, the sterilization tank according to the second embodiment will be described more specifically, but the present invention is not limited thereto.

As an example of the sterilization tank of the embodiment of the present invention, an example of a sterilization tank having a wound electrode structure having three wound electrodes is shown in FIG. FIG. 4 is a sectional explanatory view.

First, a method for producing the sterilization tank of the present invention will be described. A 30-mesh copper net made of a copper wire having a wire diameter of 0.22 mm is cut into a width of 10 cm and a length of 30 cm, and three mesh-shaped electrodes are processed at the ends and lead-out is performed from the ends. (21,22,23) Prepared.

Next, each of the copper nets has a width of 1 mm.
Three (24, 25, 26) mesh-like insulating layers each made of a polyester mesh having a size of 30 cm and a thickness of about 300 μm having a width of cm were prepared.

The copper net and the insulating layer are alternately laminated, and the
By winding it around a m core material (not shown), a wound structure having a diameter of about 4 cm was obtained. After winding a polyester mesh (27) of the same material and the same width as that used for the single-layer insulating layer on the surface of the wound structure, furthermore, the surface thereof is made of copper of the same material and the same width as that used for the electrode. Wind the mesh (28). In addition, this copper mesh was subjected to the same lead drawing process as that of the electrode.

The wound structure is housed in a cylindrical sterilization tank (29) having an inner diameter of about 4.5 cm. This disinfecting tank has a size that can just accommodate the wound structure, has a flat bottom at the bottom, is provided with a cell washing out port (30) at the center, and has an outlet (19) at the side of the bottom. Is provided.
A funnel-shaped outflow guide (31) was provided at the bottom so that the liquid could be discharged from the storage container without causing turbulence.

The wound structure is placed on the outflow guide (31), and a funnel-shaped inflow guide (3) is placed on the outflow guide (31) in order to smoothly introduce the liquid from the storage container.
2) was provided. The inlet (1) is located on the side of the inflow guide (32).
6) is provided and the structure is such that liquid does not leak from the storage container below the inlet.

After the above structure is completed, the core material is removed and a copper wire of about 0.5 mm is inserted into the core material so as to penetrate to the fungus washing port (30). Is pulled out from the upper portion of the sterilization tank container (29) while attaching a sleeve so as not to make electrical contact, thereby completing the sterilization tank main body.

Next, a circuit for driving the thus-completed sterilization tank main body portion and its operation principle will be described.

The circuit is constituted by a relay circuit or a semiconductor circuit, and includes a time for connecting to a positive electrode of a power supply electrode for generating a voltage of 0.7 V, a time for connecting to a negative electrode, and a time for not connecting to this power supply circuit. Are sequentially repeated in this order.

The sterilization tank is used to sterilize the liquid from the inlet until it flows out at the outlet. That is, at least n (n ≧ 3) in contact with the liquid from the storage container
Electrodes, a pair of electrodes of the outermost positive electrode and the central negative electrode arranged so as to sandwich these electrode structures, and a voltage within a range in which the liquid from the storage container is not electrolyzed is sequentially applied to each of the electrodes. A circuit for sweeping and applying in a certain direction is provided, the microorganisms in the liquid from the storage container can be moved to the electrode at the center, and the microorganisms can be discharged from the cell washing port.

Next, the operating principle of the sterilization tank according to the second embodiment will be described with reference to Table 1.

In this sterilization tank, microorganisms in the liquid from the storage container are attracted to the stacked electrodes, and a voltage is applied to the electrodes by sweeping to collect the microorganisms from near one electrode to the other electrode. Finally, after the movement of microorganisms is suppressed, they are discharged. During this time, the water containing microorganisms supplied to the sterilization tank is sterilized.

As an example of the structure of the sterilization tank, the structure of three wound electrodes is exemplified. However, there is no particular limitation as long as the number is three or more. The case where the number is three will be described as a representative.

First, a voltage that does not cause electrolysis of the liquid from the storage container is applied to the electrodes arranged according to the above configuration. The voltage that does not cause this electrolysis is
It is determined by the type and amount of the solvent or the electrolyte contained in the electrode and the processing solution. In the case of ordinary tap water or water containing denture cleaning agents and no special salt content, the voltage is 1 V or less.
In this sterilization tank, the voltage was 0.7 Va.

By applying such a voltage, negatively charged microorganisms can be moved to the positive electrode side by electrophoresis without deteriorating the liquid from the storage container by electrolysis. That is, by setting one of the electrodes to be negative and the other to be positive, the microorganism can be migrated from the negative portion to the positive portion. By sweeping this voltage application from the outer periphery to the inner periphery in the sterilization tank, the concentration of microorganisms in the vicinity of the electrode on the outer periphery in the container can be reduced. By continuously performing this operation and continuously removing the processing liquid on the outer peripheral side, it is possible to circulate the liquid from the storage container in which the concentration of microorganisms is reduced.

Further, the concentration of microorganisms becomes higher as the position becomes closer to the inner electrode, and a large number of microorganisms are concentrated on the innermost electrode. The microorganisms reduce their activity during repeated movements several times, and are reduced in mitotic growth by being concentrated so that the microorganisms are present in close proximity.

Since the cell washing out port (30) is provided under the innermost electrode, the collected microorganisms are continuously discharged.

The method of applying a voltage to each electrode will be described in more detail.

The application of the voltage is preferably performed in order at a certain interval in order to cause the microorganisms to migrate in a certain direction along each electrode. Therefore, it is preferable to apply a pulse potential.

Table 1 shows the movement of the microorganisms in the liquid from the storage container with respect to the voltage application state and timing for a part of the electrodes arranged in the sterilization tank having the wound electrode structure according to the second embodiment. Show.

The electrodes are a first electrode, a second electrode, and a third electrode, respectively, in the order in which the microorganisms migrate, and the first electrode,
A voltage was applied to the second electrode and the third electrode in this order, and then a voltage was again applied to the first electrode (the fourth electrode and described in the table), and the second electrode and the third electrode were sequentially repeated.

[0068]

[Table 1]

That is, a negative voltage is applied to the first electrode,
A positive voltage is applied to the second electrode, and the third electrode is not connected to a power supply. In this case, the microorganisms are attracted to the positive voltage application side and move from the first electrode to the second electrode. A negative voltage is applied to the fourth electrode, that is, the first electrode which is one round ahead, but the third electrode is not connected, so that an attraction phenomenon occurs between the second electrode and the fourth electrode, but the electrodes are separated. The inducement movement is extremely small. Therefore, at this timing, the microorganism between the first electrode and the second electrode moves from the first electrode to the second electrode.

At the next timing, the first electrode is not connected to the power source, the second electrode is connected to the negative electrode, and the third electrode is connected to the positive electrode.
Therefore, the fourth electrode, that is, the first electrode one circumference ahead is not connected. According to the same principle as described above, microorganisms between the second electrode and the third electrode move from the second electrode toward the third electrode.

At the next timing, the positive voltage is applied to the first electrode, and the third electrode is set to a state in which the second electrode is not connected to the power supply.
The electrode is connected to the negative electrode, and the fourth electrode, that is, the first electrode one circle ahead, is connected to the positive electrode. In this case as well, the movement of microorganisms toward the fourth electrode occurs between the third electrode and the fourth electrode on the same principle as described above.

In summary, if the three timings are sequentially swept, the microorganism moves from the first electrode to the fourth electrode. By sequentially performing these sweeps, the microorganisms sequentially move from the outermost electrode to the innermost electrode. This operation is performed in a sterilization tank, and the liquid to be treated flows into the vicinity of the outermost shell, thereby removing microorganisms in the liquid.

It is preferable to apply the voltage in order at regular intervals in order to cause the microorganisms to migrate in a fixed direction along each electrode. Therefore, it is preferable to apply a pulse potential.

The time from when a voltage is applied to one electrode to when the voltage is applied to the next electrode, that is, the sweeping speed, depends on the distance between the electrodes, the thickness of the electrodes, the flow rate of the liquid from the storage container, etc. Although it depends on environmental conditions such as temperature and electrolyte concentration, the speed must be substantially lower than the speed of microorganisms migrating in the electrode direction when an electric field is applied. As a result of the experiment, the present inventor found that the speed of microorganisms migrated in the microorganism concentrator of the present invention was 100 μm / sec or less. It has been found that by removing and collecting the microorganisms in a certain electrode direction, the bacteria elimination efficiency of the processing solution can be improved.

Further, the microorganism to be removed can be moved by electrophoresis when a voltage is applied. For example, Escherichia coli, Staphylococcus aureus and the like can be mentioned.

Further, the material constituting the electrode may be a conventionally used material, for example, aluminum foil,
Examples include copper foil, copper mesh, sponge metal, carbon fiber, carbon mesh, and the like.

As a material constituting the insulating layer, for example, an insulating material such as glass wool, polypropylene mesh, polyester mesh or a nonwoven fabric thereof can be used.

Further, as a result of intensive studies, the present inventor has found that it is preferable to operate the sterilization tank shown in the first embodiment under the following conditions, for example.

Applied voltage 0.7 V / between electrodes Distance between electrodes 200 μm Bacteria migration distance 20 μm / sec Bacteria migration direction Anode direction (when voltage is applied) Electrode material Copper mesh (about 100 μm thickness) Insulation layer Polyester mesh (about) 200 μm thickness In the above-described embodiment, the toothbrush and the denture cleaning / storage device have been described. However, other than the contact lens cleaning / storage device, such as a device used for medical care and the like, cleaning of non-oral devices provided with a disinfection mechanism. The same applies to storage devices.

[0080]

According to the present invention, the oral appliance cleaning / storage device provided with the disinfecting mechanism can improve the cleanliness of the oral appliance surface.
In addition, the growth of microorganisms during the stoppage of the oral appliance cleaning and storage device could be suppressed.
