Description

  The present invention relates to a cleaning / disinfecting liquid used for cleaning and disinfecting a cleaning target (for example, fingers and textiles), a wet material (for example, a cotton ball, a cotton swab, a gauze) impregnated with the cleaning / disinfecting liquid, and a cleaning The present invention relates to a disinfecting liquid manufacturing method, a cleaning disinfecting liquid manufacturing apparatus, and a cleaning disinfecting device.

  Conventionally, various techniques relating to a disinfectant and a disinfectant for cleaning and disinfecting fingers have been proposed. For example, in the automatic hand disinfector described in Patent Document 1, the control device operates the pump (disinfecting liquid sucking and disinfecting liquid spraying on the hand based on detection information from a sensor that detects the presence of the hand. ) And the generation of hot air. With this configuration, erroneous detection due to external scattered light caused by external light rays and malfunction due to electromagnetic noise are prevented.

  Moreover, the hand-washing apparatus of patent document 2 is equipped with the sterilizing water production | generation means. The sterilizing water generating means generates sterilizing water by, for example, eluting silver ions by adding electricity to a metal plate and adding it to tap water in the storage tank. In this way, since the sterilizing water generating means directly processes tap water to generate sterilizing water, the sterilizing water can be instantly sterilized at the necessary place when necessary without separately providing sterilizing water supply / drainage facilities. Sterilization with water is possible.

  However, when disinfecting an object to be sterilized using silver ion water (for example, hands), since silver ion water is not volatile, (1) remove moisture by wiping with a towel, or (2) from a blower It is necessary to dry silver ion water by blowing air. In the case of (1) above, if the towel is contaminated with bacteria, the meaning of disinfection will be lost even if it is wiped with a towel. Further, when wiping with a towel, silver may be removed at the same time, and the disinfection effect is reduced. On the other hand, in the case of the above (2), it is necessary to separately prepare a device having a blowing function such as a blower.

  On the other hand, in Patent Document 3, a silver electrode is immersed in a citric acid solution and energized, and then diluted with ethanol to obtain a bactericide containing a predetermined concentration of silver ions in a 20% ethanol solution. Is generated. In this configuration, since the silver ion water is easily volatilized, the desired sterilizing effect by the silver ions contained in the sterilizing agent can be obtained even after drying without wiping the sterilizing agent with a towel or blowing the sterilizing agent. It is considered a thing.

Patent Document 4 discloses a disinfecting cotton ball in which a cotton ball impregnated with a disinfecting disinfectant is placed in a plastic container and sealed.
Japanese Unexamined Patent Publication No. 2000-60764 (see paragraphs [0009] and [0010]) JP 2001-29439 A (see paragraphs [0005], [0009], [0012]) JP-T-2001-519361 (see paragraph [0092]) Japanese Utility Model Publication No. 2-149225

  By the way, in patent document 3, the silver ion concentration in a disinfectant is made high with 4 ppm, for example. From this, it is considered that Patent Document 3 aims to obtain a bactericidal effect by silver ions instantaneously, that is, to obtain a quick-acting bactericidal agent. When the silver ion concentration in the disinfectant is so high, silver is likely to precipitate from the disinfectant, the silver ion concentration is decreased, and the stability of the disinfectant during storage is impaired.

  Therefore, in Patent Document 3, in the process of producing a bactericidal agent containing silver ions and ethanol, the silver electrode is energized in a citric acid solution, and citric acid is included in the bactericidal agent to store the bactericidal agent. It seems that the stability of time is secured.

  On the other hand, when aiming to obtain a future bactericidal effect (hereinafter referred to as an antibacterial effect) that suppresses the adhesion and propagation of bacteria in the future rather than the instantaneous bactericidal effect due to silver ions, the silver ion concentration Need not be as high as the above concentration. That is, even when the silver ion concentration is low (for example, 10 ppb to 1 ppm), the antibacterial effect can be sufficiently obtained. Thus, when the silver ion concentration is low, the state of the bactericide is relatively stable, and silver precipitation is unlikely to occur, so citric acid for stabilization during storage is unnecessary.

  Therefore, when the antibacterial effect by silver ion is aimed at, if the disinfectant of patent document 3 is used, it will use unnecessary citric acid aqueous solution, and it will use a citric acid aqueous solution wastefully. Problems arise.

  Moreover, since the disinfectant of Patent Document 3 requires citric acid for the above-mentioned reasons, in producing the disinfectant, a two-stage process of elution of silver ions in an aqueous citric acid solution and dilution with ethanol. It is necessary to go through. As a result, there arises a problem that the production efficiency of the bactericide cannot be increased.

  Further, the disinfectant disinfectant impregnated in the cotton ball described in Patent Document 4 is considered to be, for example, general disinfecting alcohol. Since disinfecting alcohol is volatile, a cotton ball impregnated with only such disinfecting alcohol has no effect if the disinfecting alcohol volatilizes. In addition, if bacteria propagate in cotton balls or gauze, there is a risk of nosocomial infection. Therefore, the container must be opened just before use to use a cotton ball impregnated with rubbing alcohol, or the cotton ball must be soaked in rubbing alcohol each time it is used, which is not convenient. Arise.

  The present invention has been made to solve the above-described problems, and its purpose is to provide a cleaning / disinfecting solution that can be efficiently manufactured without causing waste, a manufacturing method and a manufacturing apparatus thereof, and a cleaning / disinfecting method. Is to provide a vessel. Another object of the present invention is to provide a wet material for cleaning and disinfecting that is excellent in convenience.

  (1) The cleaning / disinfecting solution of the present invention is a cleaning / disinfecting solution for cleaning and disinfecting an object to be cleaned, and includes a volatile bactericidal solvent and metal ions eluted from the metal carrier in the solvent. It is characterized by being.

  As the metal carrier, for example, a metal electrode (for example, silver electrode), a metal ion eluent (for example, silver sulfide), a metal ion eluent carrier such as zeolite or silica gel that carries them, and the like can be assumed. When the former metal carrier is used, ions of the electrode constituent metal (for example, silver ions) can be eluted by applying a voltage between the electrodes. On the other hand, when the latter metal carrier is used, the metal carrier is loaded into the cartridge, and a metal ion (for example, Silver ion) can be eluted. Moreover, as said volatile bactericidal solvent, alcohol and a petroleum-type solvent can be assumed, for example.

  In the present invention, the metal ions are eluted from the metal carrier in a volatile bactericidal solvent to obtain a cleaning / disinfecting solution containing metal ions. Thereby, first, a cleaning / disinfecting solution can be generated without using a conventional solution (for example, an aqueous citric acid solution). In the case of obtaining a future sterilization effect by metal ions, that is, an antibacterial effect, it is not necessary to increase the metal ion concentration as in the case of obtaining an instantaneous sterilization effect by metal ions. It is not necessary to include citric acid in the cleaning disinfecting solution for stabilization during storage. Therefore, according to the present invention, it is possible to produce a cleaning / disinfecting solution without producing waste in the manufacturing process even when producing a cleaning / disinfecting solution for the purpose of obtaining an antibacterial effect by metal ions.

  Secondly, in order to obtain an antibacterial effect due to metal ions, when producing a cleaning / disinfecting solution, citric acid for stabilization is not required. A cleaning / disinfecting solution containing a volatile bactericidal solvent and metal ions can be easily obtained by only one step of immersing a metal electrode in a conductive bactericidal solvent and applying current. As a result, the manufacturing efficiency of the cleaning / disinfecting liquid can be improved.

  In addition, since the cleaning / disinfecting liquid of the present invention contains a volatile bactericidal solvent, the desired antibacterial effect by the metal ions contained in the cleaning / disinfecting liquid can be sufficiently obtained even by natural drying.

  (2) In the cleaning / disinfecting solution of the present invention, the bactericidal solvent may contain alcohol.

  According to the said structure, volatilization is quick and the antimicrobial effect by a metal ion can be acquired reliably after drying. Moreover, since bacteria can be first removed with alcohol due to the bactericidal effect of alcohol, the antibacterial effect due to subsequent metal ions can be enhanced. Moreover, when the volatilization of the cleaning / disinfecting solution is fast, the particle size of the fine powder in which the metal ions are precipitated as a metal compound is reduced, and the surface area is increased. Thereby, the bactericidal and antibacterial action by the metal ion which dissolves from the metal compound can be effectively obtained.

  In addition, alcohol has a surface active action and is excellent in detergency such as oil. Therefore, the cleaning disinfectant of the present invention can be used for cleaning textile products that are not suitable for washing with water, electrical appliances that do not want to be wet with water, and their surroundings. The antibacterial treatment can also be performed with the remaining metal ions.

  In addition, the frequency of dry cleaning for a fiber product that is not suitable for washing with water can be reduced, and the cost required for cleaning can be reduced. In addition, dry cleaning is effective for organic stains, but is not effective for inorganic stains. However, since alcohol has a surface-active effect, it is possible to remove organic soils such as sebum using the cleaning and disinfecting solution of the present invention containing alcohol. For example, inorganic dirt such as mud can be removed.

  (3) In the cleaning / disinfecting solution of the present invention, the alcohol may be contained in an amount of 50% by weight or more.

  According to said structure, the above-mentioned effect by the washing | cleaning disinfection liquid of this invention containing alcohol can be acquired reliably. Further, since the volatilization of the alcohol is surely accelerated, it is possible to make it easier to exhibit an effect (for example, an antibacterial effect) peculiar to metal ions.

  (4) In the cleaning / disinfecting solution of the present invention, the metal ions may be contained in an amount of 10 ppb to 1 ppm.

  According to said structure, since metal ion concentration is low compared with the past, it is hard to precipitate a metal and it can ensure the stability at the time of the storage of a cleaning disinfection liquid, without adding a citric acid etc.

  (5) In the cleaning / disinfecting solution of the present invention, the bactericidal solvent may include an electrolyte.

The electrolyte described above, such as sodium chloride (NaCl) or sodium bicarbonate (NaHCO ₃₎ can be envisaged. When the bactericidal solvent contains such an electrolyte, the conductivity of the bactericidal solvent increases. Thereby, when elution of metal ions is performed, for example, by energizing a metal electrode (metal carrier) in a bactericidal solvent, the metal ions can be eluted at a low voltage. As a result, a cleaning / disinfecting solution can be obtained with low power consumption.

  (6) In the cleaning / disinfecting solution of the present invention, the bactericidal solvent may include tap water.

  Since tap water originally contains an electrolyte, a bactericidal solvent having high conductivity can be produced without intentionally adding an electrolyte to the bactericidal solvent. Therefore, the cleaning / disinfecting solution of the present invention can be easily obtained using tap water that is generally easily available.

  (7) In the cleaning / disinfecting solution of the present invention, the metal ions may be silver ions.

  If the metal ions contained in the cleaning / disinfecting solution are silver ions, the antibacterial effect peculiar to silver ions can be imparted to the cleaning target by cleaning the cleaning target with the cleaning / disinfecting solution of the present invention.

  (8) The wet material of the present invention is characterized by being impregnated with the above-described cleaning and disinfecting liquid of the present invention.

  According to said structure, even after volatile bactericidal solvent (for example, alcohol) volatilizes, the characteristic effect (for example, antibacterial effect) by the remaining metal ion (for example, silver ion) can be acquired. Therefore, there is no need for the conventional restriction that the sealed container containing the wet material must be opened immediately before the use of the wet material, and the wet cotton material is soaked in alcohol just before use. There is no need to create a file. Therefore, it is possible to provide a wet material that is convenient for the user and excellent in convenience.

  (9) The method for producing a cleaning / disinfecting solution of the present invention is a manufacturing method of a cleaning / disinfecting solution for cleaning and disinfecting a cleaning target, and eluting metal ions from a metal carrier in a volatile sterilizing solvent. Thus, a cleaning and disinfecting solution is produced.

  According to the above configuration, the metal ions are eluted from the metal carrier in a volatile bactericidal solvent to produce a cleaning / disinfecting solution containing metal ions. A cleaning / disinfecting solution can be produced without using an aqueous citric acid solution. For example, when trying to obtain a future antibacterial effect due to metal ions, it is not necessary to increase the metal ion concentration as much as to obtain an instantaneous sterilization effect due to metal ions, and therefore, when storing a cleaning disinfectant solution. In order to stabilize the citric acid, it is not necessary to include citric acid in the cleaning / disinfecting solution. Therefore, according to the present invention, it is possible to produce a cleaning / disinfecting solution without producing waste in the manufacturing process even when producing a cleaning / disinfecting solution for the purpose of obtaining an antibacterial effect by metal ions.

  In addition, when producing a cleaning / disinfecting solution, a cleaning / disinfecting solution containing a volatile disinfecting solvent and metal ions can be easily obtained by a single step of, for example, immersing a metal electrode in a volatile disinfecting solvent. Therefore, the production efficiency of the cleaning / disinfecting liquid can be improved.

  In addition, since a cleaning / disinfecting solution containing a volatile bactericidal solvent and metal ions is produced, the desired antibacterial effect of the metal ions contained in the cleaning / disinfecting solution can be sufficiently obtained even by natural drying.

  (10) A cleaning / disinfecting liquid manufacturing apparatus of the present invention is a cleaning / disinfecting liquid manufacturing apparatus for manufacturing a cleaning / disinfecting liquid containing metal ions, and includes an ion elution means for eluting metal ions from a metal carrier. The ion elution means is characterized by generating a cleaning / disinfecting solution containing the bactericidal solvent and the metal ions by eluting metal ions from the metal carrier in a volatile bactericidal solvent.

  (11) Further, the cleaning / disinfecting apparatus of the present invention generates a cleaning / disinfecting liquid containing the above bactericidal solvent and the metal ions by eluting the metal ions from the metal carrier in a volatile bactericidal solvent. The ion elution means which performs and the injection part which injects the said washing | cleaning disinfection liquid to the cleaning object are characterized by the above-mentioned.

  Examples of ion elution means include (i) an ion elution unit that has a metal electrode as a metal carrier and elutes metal ions by energizing the metal electrode, and (ii) a metal carrier (eg, silver sulfide). It can be assumed that metal ions (for example, silver ions) are eluted from a metal carrier simply by passing a solvent through the cartridge without applying a voltage and applying it in the cartridge.

  In the cleaning / disinfecting liquid producing apparatus and the cleaning / disinfecting apparatus of the present invention, the ion elution means elutes the metal ions from the metal carrier in the volatile bactericidal solvent, whereby the bactericidal solvent, the metal ions, Therefore, the cleaning / disinfecting liquid can be generated without using a conventional solution (for example, an aqueous citric acid solution). For example, when trying to obtain a future antibacterial effect due to metal ions, it is not necessary to increase the metal ion concentration as much as to obtain an instantaneous sterilization effect due to metal ions, and therefore, when storing a cleaning disinfectant solution. In order to stabilize the citric acid, it is not necessary to include citric acid in the cleaning / disinfecting solution. Therefore, according to the present invention, it is possible to produce a cleaning / disinfecting solution without producing waste in the manufacturing process even when producing a cleaning / disinfecting solution for the purpose of obtaining an antibacterial effect by metal ions.

  Further, in producing a cleaning / disinfecting solution, it is possible to easily obtain a cleaning / disinfecting solution containing a volatile disinfecting solvent and metal ions by only one step of eluting metal ions in a volatile disinfecting solvent. Therefore, the production efficiency of the cleaning / disinfecting solution can be improved.

  In addition, since a cleaning / disinfecting solution containing a volatile bactericidal solvent and metal ions is produced, the desired antibacterial effect of the metal ions contained in the cleaning / disinfecting solution can be sufficiently obtained even by natural drying.

  In addition, since the ion elution means and the spray unit constitute a cleaning / disinfecting device, for example, a stationary cleaning / disinfecting device (hand cleaning / disinfecting device) or a portable spray-type cleaning / disinfecting device (cleaning / disinfecting spray device) It can be easily realized. The former cleaning / disinfecting device is suitable, for example, when fingers are to be cleaned, and the latter cleaning / disinfecting device is, for example, suitable for cleaning, for example, textile products that are not suitable for washing with water. That is, the cleaning / disinfecting apparatus of the present invention can be applied to both a stationary type and a spray type.

  (12) In the cleaning / disinfecting apparatus of the present invention, the ion eluting unit may be configured to elute metal ions from the metal electrode by energizing the metal electrode as a metal carrier.

  According to the above configuration, since the selection of elution of metal ions from the metal electrode and the adjustment of the concentration of metal ions can all be performed electrically, it is easy to use and improves the convenience of the cleaning / disinfecting device. Can do.

  (13) The cleaning and disinfecting apparatus of the present invention includes a solvent container that contains the sterilizing solvent, and the sterilizing property by changing the pressure in the liquid absorption pipe that extends from the solvent container to the injection unit according to the pressing operation. In addition to controlling the supply of the solvent to the ion elution means, the pressure lever for controlling the ejection of the cleaning / disinfecting liquid generated by the ion elution means from the ejection section, and in conjunction with the pressing operation of the pressure lever Further, a configuration may be provided that further includes a control unit that controls energization to the metal electrode.

  According to said structure, when a press lever is pressed, for example, the pressure in a liquid absorption pipe will become high, and, thereby, the cleaning disinfection liquid produced | generated by the ion elution means is injected from an injection part. On the other hand, when the pressing of the pressing lever is released, the pressure in the liquid absorption pipe decreases, so that the bactericidal solvent is sucked up from the solvent container and prepared for the generation of the cleaning / disinfecting liquid in the next ion elution means.

  At this time, the control unit controls the energization to the metal electrode in conjunction with the pressing operation of the above-described pressing lever. Therefore, for example, only when the pressing lever is pressed, that is, the cleaning disinfecting liquid needs to be jetted. Only when the metal electrode is energized and metal ions are added to the bactericidal solvent to produce a cleaning disinfectant, the energization of the metal electrode can be released when the pressing lever is released.

  Thereby, the fresh thing to which the metal ion was added immediately before injection can be always provided as the cleaning disinfectant liquid to be injected. In addition, when the cleaning disinfectant is not sprayed, it is possible to create a state in which metal ions do not exist in the bactericidal solvent supplied to the ion elution means, so that metal deposits in the bactericidal solvent and the metal electrodes are short-circuited. Can be surely prevented. Further, when the cleaning / disinfecting liquid is not sprayed, it is possible to prevent the elution of useless metal ions.

  (14) In the cleaning / disinfecting apparatus of the present invention, the control unit may be configured by a switch that switches energization to the metal electrode in conjunction with the pressing operation of the pressing lever.

  By configuring the control unit with the switch, metal ions can be automatically eluted in the bactericidal solvent only by pressing the pressing lever. That is, it is not necessary to provide a means for controlling the elution timing of metal ions.

  (15) In the cleaning / disinfecting apparatus of the present invention, the switch includes a first terminal connected to one metal electrode, and a second terminal connected to the other metal electrode via a power source. The first terminal and the second terminal may be configured to switch energization to the metal electrode by being separated from and in contact with the pressing operation of the pressing lever.

  According to said structure, the switch which switches the electricity supply to the metal electrode by a power supply with a simple structure of providing a 1st terminal and a 2nd terminal so that separation | detachment in connection with the pressing operation of a press lever is realizable. it can.

  (16) The cleaning and disinfecting apparatus of the present invention is a sterilizing agent that changes the pressure in a liquid container that contains the sterilizing solvent and the suction pipe from the solvent container to the injection unit according to a pressing operation. A pressure lever that controls the supply of the solvent to the ion elution means and also controls the injection of the cleaning / disinfecting liquid generated by the ion elution means from the injection unit, and a pressure that detects the pressure in the liquid suction pipe The configuration may further include a detection unit (for example, a pressure sensor) and a control unit that controls energization of the metal electrode in accordance with a detection result of the pressure detection unit.

  According to said structure, when a press lever is pressed, for example, the pressure in a liquid absorption pipe will become high, and, thereby, the cleaning disinfection liquid produced | generated by the ion elution means is injected from an injection part. On the other hand, when the pressing of the pressing lever is released, the pressure in the liquid absorption pipe decreases, so that the bactericidal solvent is sucked up from the solvent container and prepared for the generation of the cleaning / disinfecting liquid in the next ion elution means.

  Here, the pressure detection unit detects the pressure in the liquid absorption pipe, and the control unit controls the energization to the metal electrode according to the detection result of the pressure detection unit. For example, the pressing lever is pressed. Only when the pressure in the liquid suction pipe increases, that is, only when spraying of the cleaning disinfectant is necessary, the metal electrode is energized and metal ions are added to the bactericidal solvent to generate the cleaning disinfectant, while the pressure lever When the pressure is released and the pressure in the liquid absorption pipe becomes low, the power supply to the metal electrode can be released.

  Thereby, the fresh thing to which the metal ion was added immediately before injection can be always provided as the cleaning disinfectant liquid to be injected. In addition, when the cleaning disinfectant is not sprayed, it is possible to create a state in which metal ions do not exist in the bactericidal solvent supplied to the ion elution means, so that metal deposits in the bactericidal solvent and the metal electrodes are short-circuited. Can be surely prevented. Further, when the cleaning / disinfecting liquid is not sprayed, it is possible to prevent the elution of useless metal ions.

  (17) In the cleaning / disinfecting apparatus of the present invention, the liquid absorption pipe preferably has a light shielding property.

  The metal ions in the cleaning / disinfecting solution in the liquid absorption tube may be reduced when exposed to light, and a metal or a compound thereof may be generated. In this case, the metal ion concentration in the cleaning / disinfecting solution is lowered, and even if it is jetted, an effect peculiar to metal ions (for example, antibacterial effect) may be reduced, or a short circuit may occur between a pair of electrodes of the ion elution means is there. However, if the liquid absorption tube has a light shielding property, reduction of metal ions by light can be prevented, and such inconvenience can be avoided.

  According to the present invention, the elution of metal ions from the metal carrier is performed in a volatile bactericidal solvent, so that a cleaning / disinfecting solution containing metal ions can be obtained. Even when it is not necessary to increase the metal ion concentration as in the case of the purpose, a cleaning / disinfecting solution can be generated without using a stabilizing solution (for example, an aqueous citric acid solution). Therefore, the cleaning / disinfecting liquid can be manufactured without causing waste in the manufacturing process.

  In addition, when producing a cleaning / disinfecting solution, a cleaning / disinfecting solution containing a volatile disinfecting solvent and metal ions can be easily obtained by a single step of, for example, immersing a metal electrode in a volatile disinfecting solvent. Therefore, the production efficiency of the cleaning / disinfecting liquid can be improved.

  In addition, since a cleaning / disinfecting solution containing a volatile bactericidal solvent and metal ions is produced, the desired antibacterial effect of the metal ions contained in the cleaning / disinfecting solution can be sufficiently obtained even by natural drying.

  In addition, since the wet material of the present invention is impregnated with the above-described cleaning and disinfecting liquid, a specific effect due to the remaining metal ions can be obtained even after the volatile bactericidal solvent is volatilized. Therefore, there is no need for the conventional restriction that the sealed container containing the wet material must be opened immediately before the use of the wet material, and the wet cotton material is soaked in alcohol just before use. There is no need to create a file. Therefore, it is possible to provide a wet material that is convenient for the user and excellent in convenience.

[Embodiment 1]
An embodiment of the present invention will be described below with reference to the drawings.

(1-1. Configuration of the cleaning / disinfecting device)
First, the overall configuration of a cleaning / disinfecting apparatus that is also a manufacturing apparatus for the cleaning / disinfecting liquid of the present invention will be described.

(1-1-1. Overall configuration)
FIG. 1 is a cross-sectional view showing a schematic configuration of the cleaning / disinfecting apparatus of the present embodiment. This washing / disinfecting device is a hand washing / disinfecting device for washing / disinfecting a finger as an object to be cleaned. A waste liquid container 7, a control unit 8, and communication pipes 9 and 10 are provided.

  The main body 1 accommodates the solvent container 2 and the waste liquid container 7 in the lower part thereof in a detachable manner. And the shape of the main body 1 has a flow path of the solution sucked up from the solvent container 2 so that a disinfection space (an ejection space for the cleaning disinfectant) of a disinfection target (for example, fingers) can be secured above the containers. The flow path of the cleaning / disinfecting liquid flowing out from the ion elution unit 5 is configured to bypass the disinfecting space. The shape of the main body 1 is not limited to this. Each configuration will be described below.

  The solvent container 2 contains a volatile bactericidal solvent (hereinafter also simply referred to as a solvent) that constitutes the cleaning / disinfecting solution of the present invention. As this solvent, for example, a mixture of alcohol or petroleum solvent and water can be assumed. Details of the solvent will be described later.

  The sensor 3 detects whether or not a finger to be cleaned is present in the vicinity of the ejection unit 6 that is a sterilization space, and is configured by, for example, an infrared sensor.

  When the sensor 3 detects the presence of a finger in the sterilization space, the pump 4 sucks up the solvent from the solvent container 2 and supplies it to the ion elution unit 5 through the communication pipe 9.

  The ion elution unit 5 (ion elution means) generates a cleaning / disinfecting solution containing the solvent and the metal ions by eluting the metal ions from the metal carrier in the solvent supplied from the solvent container 2 by the pump 4. . The cleaning / disinfecting liquid is supplied to the injection unit 6 through the communication pipe 10. By providing such an ion elution unit 5, metal ions can be added to a solvent that does not contain metal ions such as commercially available alcohol for disinfection. The detailed configuration of the ion elution unit 5 and the details of the cleaning / disinfecting solution of the present invention will be described later.

  The ejection unit 6 ejects the cleaning / disinfecting liquid supplied from the ion elution unit 5 toward a cleaning target (finger) in the disinfecting space, for example, in a shower shape or a mist shape.

  The waste liquid container 7 is a container for recovering, as waste liquid, a cleaning / disinfecting liquid that is dropped from the fingers after being sprayed from the ejecting unit 6 or a cleaning / disinfecting liquid that is sprayed from the ejecting unit 6 and does not hit the fingers. is there.

  The control unit 8 controls the operation of the pump 4 and the ion elution unit 5 based on the detection result of the sensor 3, and has a power source and a control circuit (not shown).

  The communication pipe 9 is a pipe connecting the pump 4 and the ion elution unit 5. More specifically, the communication pipe 9 extends vertically upward from the pump 4, bends in the horizontal direction at the height position of the ion elution unit 5, and enters an inlet 14 (see FIG. 2).

  The communication tube 10 is a tube that connects the ion elution unit 5 and the injection unit 6. More specifically, the communication pipe 10 extends horizontally from an outlet 15 (see FIG. 2), which will be described later, of the ion elution unit 5, is bent downward vertically in the vicinity of the injection unit 6, and is connected to the injection unit 6. .

(1-1-2. Configuration of ion elution unit)
Next, a detailed configuration of the ion elution unit 5 will be described.

  FIG. 2 is a horizontal sectional view showing a schematic configuration of the ion elution unit 5, and FIG. 3 is a vertical sectional view of the ion elution unit 5.

  The ion elution unit 5 has electrodes 12 and 13 in a case 11. The case 11 is made of an insulating material such as synthetic resin, silicon, or rubber. The electrodes 12 and 13 are formed in a plate shape, and are arranged in parallel with each other in the case 11 at a predetermined interval. In addition, an inlet 14 of a solvent supplied by the pump 4 is provided at one end of the case 11, and a cleaning / disinfecting solution in which metal ions are added to the solvent in the case 11 is provided at the other end. The outlet 15 is provided.

  Terminals 16 and 17 are provided at one ends of the electrodes 12 and 13, respectively. The electrode 12 and the terminal 16 and the electrode 13 and the terminal 17 are integrally formed, respectively. In addition, when these cannot be formed integrally, the junction part between an electrode and a terminal and the terminal part in case 11 are coated with a synthetic resin, a contact with water is cut | disconnected so that an electric corrosion may not arise. The terminals 16 and 17 protrude outside the case 11 and are connected to the control unit 8.

  Inside the case 11, the solvent flows parallel to the longitudinal direction of the electrodes 12 and 13. When a predetermined voltage is applied to the electrodes 12 and 13 in a state where a solvent is present in the case 11, metal ions of the electrode constituent metal are eluted from the anode side of the electrodes 12 and 13. In addition, after elution of metal ions is completed, in order to prevent the solvent from accumulating in the case 11, the bottom surface of the case 11 may be inclined so that the downstream side is lowered.

  Here, the electrodes 12 and 13 described above are, for example, silver plates having a size of about 2 cm × 5 cm and a thickness of about 1 mm, and are arranged at a distance of 5 mm. It is preferable that the metal which comprises the electrodes 12 and 13 is silver, copper, zinc, or those alloys.

Silver ions eluted from the silver electrode and zinc ions eluted from the zinc electrode are excellent in instantaneous bactericidal effect and future antibacterial effect, and copper ions eluted from the copper electrode are excellent in mold resistance. Moreover, since the ions of the component metals can be eluted simultaneously from these alloys, an excellent sterilization (antibacterial) effect and antifungal effect can be obtained. For example, in the case of a silver electrode, a reaction of Ag → Ag ⁺ + e ⁻ occurs in the electrode on the anode side, and silver ions Ag ⁺ are eluted in water.

  With such a configuration of the ion elution unit 5, the control unit 8 can select elution / non-elution of metal ions depending on whether or not voltage is applied to the electrodes 12 and 13. And the control part 8 can control the elution amount of a metal ion, in other words, the density | concentration of the metal ion in a washing | cleaning disinfection liquid, by controlling the electric current and voltage application time which flow through the electrodes 12 and 13. Therefore, for example, compared to a method of eluting metal ions from a metal ion carrier such as zeolite, selection of whether or not to introduce metal ions and adjustment of the concentration of metal ions can be performed electrically, which is convenient. Further, the control unit 8 adjusts the solvent sucking ability of the pump 4 and changes the supply amount (supply flow rate, supply rate) of the solvent supplied to the ion elution unit 5 per unit time, thereby cleaning and disinfecting liquid. It is also possible to control the metal ion concentration inside.

  The ion elution means is not limited to the ion elution unit 5 described above. For example, a metal carrier such as silver sulfide is loaded in a cartridge, and ions that elute metal ions (for example, silver ions) from the metal carrier simply by passing a solvent through the cartridge without applying a voltage. You may use as an elution means. In the present embodiment, the ion elution unit 5 is provided in the piping path (between the communication pipes 9 and 10), but may be immersed in the solvent container 2. These points can be said similarly in the following embodiments.

  Moreover, although the ion elution unit 5 demonstrated the example which has a pair of electrode 12 * 13 in this embodiment, a metal electrode does not need to be a pair (2 sheets). That is, the metal electrodes may be two pairs or three pairs, and may be two pieces for the anode and one piece for the cathode (or vice versa). The anode may be a metal electrode that elutes metal ions, and the cathode may be a carbon electrode that is not a metal.

(1-2. Operation of the cleaning / disinfecting device)
Next, the operation of the cleaning / disinfecting device having the above configuration will be described.

  When the sensor 3 detects that a finger has been inserted in the vicinity of the ejection unit 6, which is a disinfection space, the control unit 8 operates the pump 4 to suck up the solvent from the solvent container 2, and the ion elution unit via the communication pipe 9. 5 is supplied. In the ion elution unit 5, a voltage is applied between the electrodes 12 and 13 under the control of the control unit 8 to elute silver ions, which are added to a solvent to generate a cleaning / disinfecting solution. The cleaning / disinfecting liquid containing silver ions is sent to the ejecting unit 6 through the communication pipe 10 and ejected from the ejecting unit 6 toward the fingers. An excess of the cleaning / disinfecting liquid ejected from the ejection unit 6 is then collected in the waste liquid container 7.

(1-3. Effect)
As described above, the cleaning / disinfecting liquid according to the present embodiment is a cleaning / disinfecting liquid that cleans and disinfects an object to be cleaned, and includes a volatile bactericidal solvent (for example, alcohol or petroleum solvent) and a metal in the solvent. It is the structure containing the metal ion (for example, silver ion) eluted from a support body (electrode 12 * 13).

  Further, the cleaning / disinfecting liquid manufacturing apparatus of the present embodiment is a cleaning / disinfecting liquid manufacturing apparatus for manufacturing a cleaning / disinfecting liquid containing metal ions, and an ion elution means (ion elution unit) for eluting metal ions from a metal carrier. 5), wherein the ion elution means generates a cleaning / disinfecting solution containing the bactericidal solvent and the metal ions by eluting metal ions from the metal carrier in a volatile bactericidal solvent. It is.

  Further, the cleaning / disinfecting apparatus of the present embodiment is an ion that generates a cleaning / disinfecting solution containing the above-mentioned disinfecting solvent and the above-mentioned metal ions by eluting metal ions from the metal carrier in a volatile disinfecting solvent. It is the structure provided with the elution means and the injection part 6 which injects the said washing | cleaning disinfection liquid to the cleaning object.

  Further, the manufacturing method of the cleaning / disinfecting liquid according to the present embodiment is a manufacturing method of a cleaning / disinfecting liquid that cleans and disinfects an object to be cleaned, and elutes metal ions from the metal carrier in a volatile sterilizing solvent. Thus, the cleaning and disinfecting liquid is manufactured.

  In order to obtain future antibacterial effects due to metal ions, it is not necessary to increase the concentration of metal ions, and therefore citric acid is included in the cleaning disinfecting solution for stabilization during storage of the cleaning disinfecting solution. There is no need to let them. Therefore, according to the present invention, it is possible to produce a cleaning / disinfecting solution without producing waste in the manufacturing process even when producing a cleaning / disinfecting solution for the purpose of obtaining an antibacterial effect by metal ions.

  Further, in producing a cleaning / disinfecting solution, it is possible to easily obtain a cleaning / disinfecting solution containing a volatile disinfecting solvent and metal ions by only one step of eluting metal ions in a volatile disinfecting solvent. Therefore, the production efficiency of the cleaning / disinfecting solution can be improved.

  In addition, since citric acid used in the past is an acid, when an aqueous citric acid solution is used, it causes corrosion when concentrated at high concentrations or by volatilization of the solvent. If you touch it, it may cause itching. However, according to the present invention, since a cleaning / disinfecting solution can be generated without using such an aqueous citric acid solution, there is no concern specific to such an acid.

  In addition, since a cleaning / disinfecting solution containing a volatile bactericidal solvent and metal ions is produced, the desired antibacterial effect of the metal ions contained in the cleaning / disinfecting solution can be sufficiently obtained even by natural drying.

  Furthermore, the cleaning / disinfecting device manufactured by the manufacturing apparatus is reliably supplied to the object to be cleaned by configuring the cleaning / disinfecting solution manufacturing apparatus and the injection unit 6 described above. Thereby, the stationary cleaning / disinfecting device (hand cleaning / disinfecting device) shown in FIG. 1 can be easily realized.

  In addition, you may make it provide a forced-drying means (for example, fan) which forcibly dries the cleaning disinfectant sprayed to the cleaning object by ventilation. In this case, the antibacterial effect of metal ions can be exerted on the object to be cleaned by forced drying even when a low-volatile solvent other than alcohol-based solvents (for example, benzalkonium chloride) is used.

  In addition, although this embodiment demonstrated the example which electrolyzes in a volatile bactericidal solvent, it is not necessarily limited to this. For example, electrolysis may be performed in water and then mixed with a bactericidal solvent. Alternatively, electrolysis may be performed in a solution obtained by mixing a bactericidal solvent and water.

  Therefore, the cleaning / disinfecting liquid of the present invention is a cleaning / disinfecting liquid that cleans and disinfects the object to be cleaned, and includes a volatile bactericidal solvent and metal ions eluted from the metal carrier in the liquid containing the solvent. It can be said that it may be the structure containing.

(1-4. About cleaning disinfectant)
Next, the details of the cleaning / disinfecting solution of the present invention will be described.

(1-4-1. About solvent)
As the solvent constituting the cleaning / disinfecting solution of the present invention, as described above, a mixture of alcohol or petroleum solvent and water can be considered. By using such a solvent, the volatility of the cleaning / disinfecting solution after the addition of metal ions can be increased, so that the desired antibacterial effect of the metal ions contained in the cleaning / disinfecting solution can be reliably exhibited. it can.

  In particular, as the alcohol, for example, ethanol, methanol, isopropyl alcohol, and a mixture thereof can be considered. By mixing such an alcohol with a cleaning / disinfecting solution, the following effects can be obtained.

  First, by using a cleaning / disinfecting solution containing alcohol and silver ions, it is possible to obtain a cleaning / disinfecting solution that has rapid volatilization and has an antibacterial effect even after drying.

  Second, the antibacterial effect of silver is reduced when there are many bacteria or when there is dirt, but the bactericidal effect of alcohol is relatively low even when there are a large amount of bacteria or when there is dirt other than bacteria. High and has the effect of removing them. Therefore, by mixing alcohol and silver ions to form a cleaning / disinfecting solution as in the present invention, bacteria can be first removed with alcohol, so that the antibacterial effect of silver ions can be enhanced.

  Third, when the cleaning / disinfecting solution containing silver ions is dried, the silver ions remain as fine powders such as metallic silver and silver compounds. Then, when silver ions are eluted from their surfaces when they are next exposed to moisture, the silver ions bring about a bactericidal and antibacterial action. As in the present invention, by mixing silver ions and alcohol and increasing the volatilization rate of the cleaning disinfectant, the particle size of the fine powder is reduced and the surface area is increased. Can be obtained effectively.

  In addition, if there is no water around, silver ions will not be eluted, but in an environment where there is no water completely, the bacteria will be killed, so there is no problem.

  Fourth, since alcohol has a surface active action and is excellent in cleaning power such as oil, the cleaning disinfectant of the present invention containing alcohol is used for cleaning dishes and the like as well as the above-described cleaning of fingers. It can also be used for applications. In addition, since the alcohol volatilizes, subsequent washing with water can be eliminated. Further, if the alcohol concentration is sufficiently high, the volatilization is faster, so that it is not necessary to wipe with an empty wipe or cleaning disinfectant.

  Therefore, for example, fiber products made of hair, silk, rayon, acetate, cupra, etc. and specially processed fiber products may remain wet for a long time or may be subjected to force while touching water. Then, since the fiber is damaged, it cannot be washed with water, but the cleaning / disinfecting solution of the present invention can also be used for cleaning the above-mentioned textile products that are not suitable for washing with water, electrical appliances that do not want to be wet with water, and their surroundings. Furthermore, at the same time as such washing, antibacterial treatment can be performed with the remaining silver.

  Fifth, the above-mentioned textile products that are not suitable for washing with water are often dry-cleaned. However, dry cleaning is expensive, so it cannot be performed frequently. Also, dry cleaning is effective for organic stains but is not effective for inorganic stains.

  However, since the volatile cleaning / disinfecting solution of the present invention containing alcohol and silver ions is quick to dry and does not damage the textile even when used for these textiles, The frequency of dry cleaning can be lowered by washing the easily contaminated part. Moreover, since the part which is easy to get dirty is also a part where various germs are easy to propagate, if the antibacterial effect is obtained at the same time, the merit is great. Furthermore, since alcohol has a surface-active effect, it can remove organic soils such as sebum. Furthermore, since the cleaning / disinfecting solution of the present invention is an aqueous solution, it is possible to remove inorganic soils such as dust, sand and mud Can also be dropped.

  At this time, as a method of cleaning the textile product with the cleaning / disinfecting liquid, an immersion method in which the textile product is immersed in the cleaning / disinfecting liquid may be used. Alternatively, the textile product may be hung on a hanger or the like, and a large amount of the cleaning / disinfecting solution may be sprayed thereon, and then the cleaning / disinfecting solution soaked into the textile product may be sucked into another cloth or the like. In this case, since there is no case where an inadvertent force is applied when the textile is in a wet state, the textile can be made more difficult to be damaged.

  In the cleaning / disinfecting solution of the present invention, it is desirable that the cleaning / disinfecting solution contains 50% by weight or more of alcohol in order to surely obtain the first to fifth effects described above. It has been experimentally found that it is desirable to contain 70% by weight or more. Therefore, as the cleaning / disinfecting solution of the present invention, for example, (1) a solvent composed of 70% by weight of ethanol and 30% by weight of water and 900 ppb of silver ions, or (2) 50% by weight of isopropyl alcohol. %, And a solvent composed of 50% by weight of water to which 900 ppb of silver ions are added.

By the way, when said solvent consists only of alcohol and water (distilled water), the electrical conductivity of a solvent is low and a high voltage is needed in order to perform electrolysis in the ion elution unit 5. FIG. Therefore, a configuration may be adopted in which the conductivity of the solvent is increased by adding an electrolyte to the solvent. Examples of the electrolyte in this case include sodium chloride (NaCl) and sodium hydrogen carbonate (NaHCO ₃ ). Thereby, since the electrolysis in the ion elution unit 5 can be performed at a low voltage, it is possible to reduce the power consumption of the ion elution unit 5 and thus the entire cleaning / disinfecting device.

  Since tap water contains an electrolyte, tap water may be mixed instead of adding the electrolyte to the solvent. Since tap water is inexpensive and very easy to obtain, a solvent to which silver ions are added can be easily made simply by mixing tap water with commercially available ethanol or the like. In addition, although tap water may contain bacteria a little unlike distilled water, since they can also be killed by the action of alcohol and metal ions, there is no problem.

(1-4-2. About metal ion concentration)
Next, the metal ion concentration in the cleaning / disinfecting solution of the present invention will be described.

  In the present invention, since the solvent contains a volatile bactericidal solvent (for example, alcohol), the metal ion concentration in the cleaning / disinfecting liquid is set to 10 ppb or more and 1 ppm or less.

  When the metal ion concentration in the cleaning / disinfecting solution is lower than 10 ppb, an effect peculiar to the metal ion (for example, an antibacterial effect) is not effectively exhibited. On the other hand, if the metal ion concentration is higher than 1 ppm, the metal is liable to precipitate and the stability during storage of the cleaning / disinfecting solution is impaired, and the metal ion concentration is lowered due to the metal precipitation.

  However, in the cleaning / disinfecting solution of the present invention, the state of the cleaning / disinfecting solution is relatively stable at a metal ion concentration in the above range, and metal deposition is unlikely to occur. It can be almost avoided that the ion concentration decreases with time. Therefore, it is not necessary to use citric acid for stabilizing the solution, and stability during storage of the cleaning / disinfecting solution can be ensured.

  In the cleaning / disinfecting solution of the present invention, the metal ion concentration is lower than the conventional one (for example, 4 ppm in Patent Document 3) because the metal ions are not expected to have an instantaneous sterilizing effect. Incidentally, the instantaneous bactericidal effect is brought about by alcohol.

  In the present invention, since the electrodes 12 and 13 of the ion elution unit 5 are composed of silver electrodes, the metal ions contained in the cleaning / disinfecting solution are silver ions. Thereby, the future antibacterial effect peculiar to silver ion can be given to the washing object by washing the washing object with the washing and disinfecting liquid.

(1-5. Wetting material)
The above-described cleaning / disinfecting solution of the present invention can be applied to wet materials. That is, the wet material can be constituted by impregnating the cleaning / disinfecting solution of the present invention.

  Here, as the wet material, for example, a water retention material such as a cotton ball, a cotton swab, a gauze, a wet tissue, a paper napkin, a cloth or a nonwoven fabric, or a water retention fiber such as a towel can be assumed.

  Conventionally, cotton balls impregnated only with alcohol for disinfection had no effect as a disinfectant after the alcohol volatilized. However, if the wet material is constituted by impregnating a cleaning / disinfecting solution containing a volatile bactericidal solvent (for example, alcohol) and metal ions (for example, silver ions) as in the present invention, even after the alcohol has volatilized, The antibacterial effect due to the remaining metal ions can be obtained.

  Therefore, the wet material can be used without imposing the restriction that the sealed container containing the wet material must be opened immediately before the use of the wet material. In addition, there is no need to immerse a dry cotton ball in alcohol immediately before use to prepare a wet material. Therefore, it is possible to provide a wet material that is convenient for the user and excellent in convenience.

  Moreover, since the alcohol disinfectant loses its effect when it volatilizes, it is ineffective against bacterial contamination after drying. On the other hand, cotton balls or the like are generally not used only in a state of being soaked in alcohol, and are often required to be used in a dry state. In that case, if the bacteria are not completely removed at the time of disinfection with a cotton ball or the like, there is a possibility that the bacteria will reproduce again after volatilization of alcohol. However, if a wet material impregnated with a cleaning and disinfecting solution using a combination of metal ions and alcohol as in the present invention is used, in addition to the disinfecting effect due to the alcohol, the antibacterial effect due to the remaining metal ions after the volatilization of the alcohol Thus, the growth of bacteria can be suppressed.

[Embodiment 2]
Another embodiment of the present invention will be described below with reference to the drawings.

(2-1. Overall configuration)
FIG. 4 is a cross-sectional view showing a schematic configuration of a cleaning / disinfecting apparatus which is also a manufacturing apparatus for the cleaning / disinfecting liquid according to the present embodiment. This cleaning / disinfecting device is a so-called spray-type cleaning / disinfecting device, and includes a solvent container 21 and a handle 22.

  The solvent container 21 contains the volatile bactericidal solvent described in the first embodiment (hereinafter simply referred to as a solvent). The solvent container 21 has, for example, a substantially flask shape, and only the uppermost part is open.

  The handle portion 22 is a portion that is gripped by the user, and is detachably provided in the solvent container 21 so as to close the opening of the solvent container 21. The handle portion 22 includes a liquid absorption tube 23, an ion elution unit 24, an injection portion 25, check valves 26 and 27, a pressing lever 28, and a control portion 29.

  The liquid absorption pipe 23 is a pipe for securing a flow path of the solvent or the cleaning / disinfecting liquid from the solvent container 21 to the injection unit 25 through the ion elution unit 24. The liquid absorption pipe 23 is provided so as to penetrate the inside of the handle portion 22, and extends from the lower end of the handle portion 22, that is, from the end surface on the opening side of the solvent container 21 to the vicinity of the bottom surface of the solvent container 21. .

  Moreover, the liquid absorption pipe | tube 23 is comprised with resin which has light-shielding property. As a result, in the cleaning / disinfecting liquid flowing in the liquid absorption pipe 23, it is possible to avoid a metal ion being reduced by light and a metal or a compound thereof being deposited, and a short circuit between the metal electrodes in the ion elution unit 24 can be avoided. .

  The ion elution unit 24 (ion elution means) is a cleaning / disinfecting solution containing a solvent and metal ions by eluting metal ions from the metal carrier in the solvent sucked up from the solvent container 21 by pressing the pressing lever 28. Is generated. The ion elution unit 24 has the same configuration as that of the ion elution unit 5 shown in the first embodiment, and is provided in the middle of the liquid absorption tube 23.

  The ejection unit 25 ejects the cleaning / disinfecting liquid supplied from the ion elution unit 24 in a mist toward the object to be cleaned, and the tip has an atomization structure.

  The check valve 26 is provided at the end of the liquid suction pipe 23 on the side of the solvent container 21. When the pressure in the liquid suction pipe 23 changes, the solvent and the cleaning / disinfecting liquid in the liquid suction pipe 23 are replaced with the solvent container 21. Prevents backflow to the side.

  The check valve 27 is provided on the side of the injection unit 25 in the liquid absorption pipe 23, and prevents outside air from flowing into the liquid absorption pipe 23 from the injection unit 25 when the pressure in the liquid absorption pipe 23 changes. .

  The pressing lever 28 controls the supply of the solvent in the solvent container 21 to the ion elution unit 24 by changing the pressure in the liquid absorption pipe 23 extending from the solvent container 21 to the injection unit 25 according to the pressing operation. The injection of the cleaning / disinfecting liquid generated by the ion elution unit 24 from the injection unit 25 is controlled.

  More specifically, a piston 30 is connected to the pressing lever 28. The piston 30 moves in the cylinder 31 communicating with the inside of the liquid suction pipe 23 in accordance with the pressing operation of the pressing lever 28. The pressing lever 28 is biased in a direction to release the pressing by a biasing means such as a spring (not shown).

  Accordingly, when the pressing lever 28 is pressed, the pressure in the liquid suction pipe 23 increases due to the movement of the piston 30, and the cleaning / disinfecting liquid generated in the ion elution unit 24 is jetted from the jetting unit 25.

  On the other hand, when the pressing of the pressing lever 28 is released, the pressing lever 28 returns to the original position by the biasing means, and the piston 30 moves in the opposite direction. As a result, the pressure in the liquid absorption pipe 23 is reduced, so that the solvent in the solvent container 21 is sucked into the liquid absorption pipe 23 and is prepared for the generation of the cleaning / disinfecting liquid in the next ion elution unit 24.

  In this way, according to the pressing operation of the pressing lever 28, the solvent in the solvent container 21 is supplied to the ion elution unit 24 and the cleaning / disinfecting liquid generated in the ion elution unit 24 from the injection unit 25. Injection is controlled.

  The controller 29 controls the energization of the electrodes of the ion elution unit 24 in conjunction with the pressing operation of the pressing lever 28, and has a power source and a control circuit (not shown). For example, when a pressing detection unit (not shown) detects the pressing of the pressing lever 28, the control unit 29 energizes the pair of electrodes of the ion elution unit 24 to elute metal ions from the electrodes and add them to the solvent. On the other hand, when the press detection unit detects the release of the pressing lever 28, the control unit 29 releases the energization to the electrode and stops the elution of the metal ions.

(2-2. Operation of the cleaning / disinfecting device)
Next, the operation of the cleaning / disinfecting device having the above configuration will be described.

  When the user presses the pressing lever 28 (pulls the pressing lever 28), the control unit 29 energizes the electrode of the ion elution unit 24 to elute metal ions (for example, silver ions) into the solvent. As a result, a cleaning / disinfecting solution containing the solvent and metal ions is generated in the ion elution unit 24. Further, since the piston 30 is moved by the pressing of the pressing lever 28 and the pressure in the liquid absorption pipe 23 is increased, the cleaning / disinfecting liquid generated in the ion elution unit 24 is the liquid absorption pipe 23 and the check valve 27. The fuel reaches the injection unit 25 and is injected from the injection unit 25 toward the external cleaning target.

  In addition, if the cleaning / disinfecting liquid is filled in the liquid suction pipe 23, the cleaning / disinfecting liquid is ejected from the injection unit 25 as described above, but if the cleaning / disinfecting liquid is not filled in the liquid suction pipe 23, as described above. The air in the liquid suction pipe 23 is just blown out from the injection unit 25. Further, if the liquid suction tube 23 is not filled with the cleaning / disinfecting liquid, the metal ions will not be eluted even when the electrode is energized.

  On the other hand, when the pressing of the pressing lever 28 is released, the control unit 29 stops energizing the electrodes, and the pressure in the liquid suction pipe 23 decreases due to the movement of the piston 30 in the opposite direction. As a result, the solvent in the solvent container 21 is sucked into the liquid suction pipe 23 via the check valve 26. Thereafter, this operation is repeated.

(2-3. Effect)
As described above, the cleaning / disinfecting liquid manufacturing apparatus according to the present embodiment is a cleaning / disinfecting liquid manufacturing apparatus that manufactures a cleaning / disinfecting liquid containing metal ions, and includes an ion elution means for eluting metal ions from a metal carrier ( The ion elution means includes an ion elution unit 24), and the ion elution means elutes metal ions from the metal carrier in a volatile bactericidal solvent, thereby cleaning and disinfecting liquid containing the bactericidal solvent and the metal ions. It is the structure to generate.

  Further, the cleaning / disinfecting apparatus of the present embodiment is an ion that generates a cleaning / disinfecting solution containing the above-mentioned disinfecting solvent and the above-mentioned metal ions by eluting metal ions from the metal carrier in a volatile disinfecting solvent. It is the structure provided with the elution means and the injection part 25 which injects the said washing | cleaning disinfection liquid to the washing | cleaning target.

  Further, the manufacturing method of the cleaning / disinfecting liquid according to the present embodiment is a manufacturing method of a cleaning / disinfecting liquid that cleans and disinfects an object to be cleaned, and elutes metal ions from the metal carrier in a volatile sterilizing solvent. Thus, the cleaning and disinfecting liquid is manufactured.

  Thus, the cleaning / disinfecting liquid manufacturing apparatus, the cleaning / disinfecting device manufacturing method, and the cleaning / disinfecting device equivalent to those in the first embodiment can be realized, so that the same effects as those in the first embodiment can be obtained.

  In addition to the above-described configuration, the cleaning / disinfecting apparatus according to the present embodiment is adapted to press the pressure in the solvent container 21 containing the sterilizing solvent and the pressure in the liquid suction pipe 23 extending from the solvent container 21 to the injection unit 25. A pressure lever 28 for controlling the supply of the bactericidal solvent to the ion elution means and controlling the injection of the cleaning / disinfecting liquid generated by the ion elution means from the injection unit 25; In conjunction with the pressing operation of the pressing lever 28, the control unit 29 further controls the energization of the metal electrode of the ion elution means.

  Thereby, as the cleaning / disinfecting liquid ejected from the ejection unit 25, a fresh one to which metal ions are added immediately before ejection can be always provided. In addition, when the cleaning disinfectant is not sprayed, it is possible to create a state in which metal ions do not exist in the bactericidal solvent supplied to the ion elution means, so that metal deposits in the bactericidal solvent and the metal electrodes are short-circuited. Can be surely prevented. Further, when the cleaning / disinfecting liquid is not sprayed, it is possible to prevent the elution of useless metal ions.

  In addition, spraying and disinfecting a cleaning and disinfecting solution containing metal ions and a volatile bactericidal solvent in a mist form allows disinfection and cleaning. Since the molecules are small and easily volatilized, the effect of the cleaning / disinfecting solution containing metal ions can be more easily exhibited.

[Embodiment 3]
The following will describe still another embodiment of the present invention with reference to the drawings. In addition, the same member number is attached to the same structure as Embodiment 1 * 2, and the description is abbreviate | omitted.

  FIG. 5 is a cross-sectional view showing a schematic configuration of a main part of the cleaning / disinfecting apparatus of the present embodiment. As shown in the figure, in the present embodiment, the pressure sensor 41 is provided in the handle portion 22 in the cleaning / disinfecting apparatus of the second embodiment. In the present embodiment, the ion elution unit 24 is provided in the vicinity of the ejection unit 25, that is, closer to the ejection unit 25 than the solvent container 21 in the liquid absorption pipe 23.

  The pressure sensor 41 (pressure detection unit) detects the pressure in the liquid suction pipe 23. In the present embodiment, the control unit 29 controls energization to the electrode of the ion elution unit 24 according to the detection result of the pressure sensor 41.

  For example, when the pressing lever 28 is pressed, the pressure in the liquid suction pipe 23 increases due to the movement of the piston 30. When the pressure sensor 41 detects that the pressure in the liquid absorption pipe 23 has become a predetermined value or more, the control unit 29 energizes the electrode of the ion elution unit 24 to elute the metal ions into the solvent.

  On the other hand, when the pressing of the pressing lever 28 is released, the pressure in the liquid suction pipe 23 decreases due to the reverse movement of the piston 30. When the pressure sensor 41 detects that the pressure in the liquid absorption pipe 23 has become a predetermined value or less, the control unit 29 releases the energization to the electrode of the ion elution unit 24.

  As described above, the cleaning / disinfecting apparatus according to the present embodiment includes the pressing lever 28 and the pressure detection unit (pressure sensor 41) that detects the pressure in the liquid suction pipe 23 in the configuration of the cleaning / disinfecting apparatus according to the second embodiment. The control unit 29 controls the energization of the electrode of the ion elution means in accordance with the detection result of the pressure detection unit.

  As a result, the pressure lever 28 is pressed to increase the pressure in the liquid suction pipe 23, and the metal ion is eluted by the ion elution means to generate the cleaning / disinfecting liquid only when the cleaning / disinfecting liquid needs to be ejected. it can. On the other hand, when the pressing of the pressing lever 28 is released and the pressure in the liquid suction pipe 23 is reduced, the elution of metal ions can be stopped.

  Therefore, the same effects as those of the second embodiment can be obtained, for example, as a cleaning / disinfecting liquid ejected from the ejection unit 25, a fresh one to which metal ions are added immediately before ejection can be always provided.

  Further, in the liquid absorption tube 23, the solvent may accumulate on the ejection unit 25 side of the ion elution means (ion elution unit 24) due to the suction from the solvent container 21. Metal ions cannot be added by means. However, as in this embodiment, by disposing the ion elution means in the vicinity of the injection unit 25, the amount of the solvent present on the injection unit 25 side relative to the ion elution means, that is, a solvent to which metal ions cannot be added. Can be reduced as much as possible. Thereby, the cleaning disinfection liquid containing a metal ion can be made effectively. It should be noted that the configuration in which the ion eluting means is arranged as described above can be applied to the second embodiment and the fourth embodiment to be described later.

[Embodiment 4]
The following will describe still another embodiment of the present invention with reference to the drawings. In addition, the same member number is attached to the same structure as Embodiment 1 thru | or 3, and the description is abbreviate | omitted.

  6 (a) and 6 (b) are cross-sectional views showing a schematic configuration of the main part of the cleaning / disinfecting apparatus of the present embodiment, and FIG. 6 (a) is a case where the cleaning / disinfecting apparatus is viewed from the back side. A cross-sectional view is shown, and FIG. 6B shows a cross-sectional view when the cleaning / disinfecting liquid is viewed from the side. As shown in these drawings, in the present embodiment, a control unit 51 is used instead of the control unit 29 in the cleaning / disinfecting apparatus of the second embodiment.

  Similarly to the control unit 29, the control unit 51 controls the energization of the electrodes 12 and 13 of the ion elution unit 24 in conjunction with the pressing operation of the pressing lever 28. In the present embodiment, the control lever 51 The switch is configured to switch the energization to the electrodes 12 and 13 of the ion elution unit 24 in conjunction with the pressing operation 28.

  This switch has a first terminal 52 and a second terminal 53. The first terminal 52 is connected to one electrode 12 of the ion elution unit 24 and is fixed to the side surface of the liquid absorption tube 23. The second terminal 53 is connected to the other electrode 13 via a battery 54 (power source). The second terminal 53 is connected to the pressing lever 28 via a spring 55 (biasing means), and can reciprocate in the pressing direction of the pressing lever 28. Thereby, the second terminal 53 can be separated from and connected to the first terminal 52 in conjunction with the pressing operation of the pressing lever 28.

  In the above configuration, when the pressing lever 28 is pressed, the second terminal 53 moves toward the first terminal 52 along with the movement of the pressing lever 28 and eventually comes into contact with the first terminal 52. Thereby, the switch which comprises the control part 51 is set to ON, and a 1st terminal 52, the 2nd terminal 53, the battery 54, the electrode 13, the solvent in the ion elution unit 24, and the electrode 12 form an annular loop. As a result, current flows through the electrodes 12 and 13, and metal ions (for example, silver ions) are eluted from the electrode serving as the anode.

  On the other hand, when the pressing of the pressing lever 28 is released, the pressing lever 28 moves in a direction to return to the original position by an urging means (not shown). Accordingly, the second terminal 53 moves away from the first terminal 52. Moving. As a result, the switch constituting the control unit 51 is turned off and the loop is cut, so that no current flows through the electrodes 12 and 13 and the elution of metal ions stops.

  As described above, in the present embodiment, the control unit 51 is configured by the switch that switches the energization to the electrodes 12 and 13 of the ion elution unit 24 in conjunction with the pressing operation of the pressing lever 28. By only the pressing operation 28, the ion elution unit 24 can automatically elute metal ions into the solvent.

  The switch includes a first terminal 52 connected to one electrode 12 of the ion elution unit 24, and a second terminal 53 connected to the other electrode 13 via a power source (battery 54). The first terminal 52 and the second terminal 53 are configured to switch the energization to the electrodes 12 and 13 when they are separated from each other in conjunction with the pressing operation of the pressing lever 28. Thereby, the switch which switches automatically the electricity supply to the electrodes 12 and 13 by a power supply is realizable with a simple structure.

  Further, in the present embodiment, depending on the adjustment of the size and installation position of the first terminal 52 and the second terminal 53 and the adjustment of the urging force of the spring 55, the switch other than when the pressing lever 28 is in the original position is used. Can be entered. In this case, electrolysis is performed and the metal ions are eluted in the solvent drawn into the liquid absorption tube 23 only after the pressing lever 28 is pulled back to the original state.

  When the ion elution unit 24 is attached to a place where the solvent sucked up from the solvent container 21 is accumulated in the liquid absorption tube 23, the metal ion concentration generally depends on the amount of the solvent and the electrolysis time. . However, in this embodiment, the amount of the solvent drawn into the liquid absorption tube 23 by one operation of the pressing lever 28 is substantially constant, and the time for “pulling” and “returning” the pressing lever 28 is also substantially constant. Therefore, the metal ion concentration in the cleaning / disinfecting solution can be made almost constant. In addition, since the metal ions are added only to the solvent in the liquid absorption tube 23, the minimum ion elution amount can be achieved.

  The present invention can be used for, for example, a cleaning / disinfecting liquid for cleaning and disinfecting fingers and textile products, wet materials such as cotton balls and gauze used in that case, a manufacturing apparatus and a manufacturing method for the cleaning / disinfecting liquid, a cleaning / disinfecting device, and the like.
