The present invention relates to a device that can be used while generating disinfectant water in a container having a portable size, and carrying the container directly and spraying it where necessary. The invention is a combination of the invention of the sprayer which can be sprayed and the invention of the device which supplies and controls the electricity required for the generation of the disinfectant water.

In modern times, the population is densely populated, group meals and meals are frequent, and the movement of the population is large due to the development of transportation. Accordingly, bacterial infectious diseases frequently occur and are becoming widespread. In this situation, the importance of hygiene cannot be overemphasized. In accordance with such living conditions, various kinds of disinfecting water generating devices have been developed and used.

Korean Patent No. 10-0443894 (sterilization water generating device) takes a method of generating disinfectant water by generating an electrolytic reaction to water added with a small amount of salt to generate sodium hypochlorite (NaOCl), and domestic patent 10-0465858 (body and The tableware killing washing system) takes a method of generating disinfectant water by generating hypochlorous acid (HClO) by causing an electrolytic reaction to water to which a small amount of salt is added. Takes the method of generating disinfectant water by generating hydrogen peroxide and active oxygen in the water by electric discharge, and the Korean Utility Model 20-0323948 (sterilization disinfectant generator) produces disinfectant water by making water into strong acidic oxidized water. There is something suspicious.

All of the above disinfection water generators have a large water tank or directly connect the water pipe to the disinfection water generator, and are large devices equipped with a large spray device. Such a large disinfectant generator can be effectively used in a large space such as a barn, a kitchen of a large restaurant, a public toilet, but cannot be used in a narrow space such as a kitchen or a bathroom of a general home. And the price of the equipment is very expensive.

As described above, the conventional sterilizing water generators are both large and expensive, and are not suitable for use in homes or other narrow spaces. In addition, the effect of sterilization may be questionable depending on the type of device.

Accordingly, a disinfectant generator that is easy to carry, can be used in a small space, is simple to operate and operate, and has low maintenance cost is required. In addition, such a disinfecting water generator should have a sterilizing effect which is a unique function.

The present invention portable electrolytic disinfection water generating device is small and light, easy to carry, can be used easily even in narrow places, the generation of disinfecting water is very simple, easy to maintain, developed to implement a sterilizing device with a certain sterilization effect It became.

Portable electrolytic sterilizing water generating device of the present invention is largely composed of a disinfection water generator 100 and the stand (200). The sterilizing water generator is composed of a container 110 containing the sterilizing water, a sprayer 120 for spraying the sterilizing water where necessary, and a power supply 130 including an electrode. And the stand is composed of the body 210, the display adjustment unit 220, the power supply 230, the external electric lead wire 240 and the connection terminal 250.

The sterilizing water generator is manufactured in a bottle shape as shown in FIG. 1.

The material of the container 110 may be any material, but should be a material that is not corroded or soluble by hypochlorous acid or sodium hypochlorite, which are main components of disinfectant water. Plastic systems such as are preferred. The container 110 serves as an electrolytic reactor together with storing the generated disinfecting water.

As the injector 120 of the sterilizing water generator, a stopper type spray injector of a container generally used may be manufactured integrally with the cap of the container.

As an example of this injector, as shown in Fig. 1, a tube 121 having a pump 121 for injecting air into the container is attached to the top of the stopper and attached to the bottle. A check valve 122 is attached to prevent backflow of the disinfectant water, and there is a discharge pipe 123 connected to the nozzle inlet of the bottle cap to supply the disinfectant solution to the nozzle. There is a trigger 124 at the handle 125. And the discharge pipe 123 is through the nozzle 126.

In another embodiment of the injector, if the disinfection water container is very small, a grip type injector, which is attached to the side of the stopper and which combines a trigger and a pump compressor, may be used, such as a general detergent spray. .

The stopper of the container integrally with the injector is attached to a pressure reducing valve or cock 127, so that it is possible to discharge the hydrogen gas generated when disinfecting water is generated.

As shown in the detailed view of FIG. 2, the power supply unit 130 of the sterilizing water generator is supplied with electricity from the positive electrode and the negative electrode of two electrodes 131 and the stand 200, and an electric terminal for supplying electricity to the electrode. 132, and the body 133.

The electrode 131 may use a conventional metal electrode. However, when used for a long time, the anode (+ electrode) has a problem of shortening the life due to electric corrosion as the electrons continue to emit electrons, so that the anode has a durable platinum group electrode. It is good to use.

If the disinfectant generator is used for a long time, there is a problem that the negative electrode (-pole) is scaled and the production rate of the disinfecting component is slowed. In order to prevent this, it is necessary to change the anode and the cathode from time to time. In this case, since both electrodes may be used as the anode, in contrast, both electrodes may use a platinum group electrode.

The shape of the electrode is generally produced in the form of a plate having a constant width, but two cylindrical or different diameter cross-sectional electrodes of different cross-sectional dimensions may be manufactured by arranging the axes concentrically. In the case of using such concentric electrodes, it is preferable to form a large number of holes in the wall so that the generated disinfectant water is well discharged out of the electrode and diffused well throughout the disinfectant generator.

It is also possible to shorten the generation time of disinfectant water by using two or more pairs of electrodes connected in parallel to one power supply unit 130 or by using a plurality of different electrodes on one electrode.

The electrical supply terminal 132 may be in any form to be in contact with the two electrical contacts connected to the mounting groove of the stand body, but the socket-type terminal installed at the bottom of the recently released wireless electric port is convenient. . This socket-type electric terminal is installed to protrude in the center of the bottom of the mounting groove, the contact portion has a short truncated conical shape, one terminal is shown on the outside, and another round terminal is contained in the inside. If you put the container of the disinfectant generator on the mounting groove, power is automatically connected to the electrode of the disinfectant generator. Since the electricity supplied to the electrodes of the sterilizing water generator basically uses a direct current, it is good to prevent the confusion of the electrode by using the internal contact of the terminal as the positive electrode and the external contact as the negative electrode according to the convention of electrical wiring.

The two contacts of the electrical supply terminal 132 and the two electrodes 131 are respectively connected by wires, and the body 133 is molded by integrally molding them. This body is good to be assembled by screwing to the bottom of the container to be removable for cleaning and replacement of the electrode, for this purpose to form a screw thread on the outer side of the body 133, the upper surface to prevent leakage of disinfectant water It is preferable to form grooves for installing sealing materials 134 such as O-rings and gaskets.

In addition to the screw method as described above, the electrical supply terminal and the container can be connected to a flange, which forms a connection flange on the upper part of the body 133 and directly connects the screw by processing a screw hole in the bottom of the container. Do.

Stand 200 can be produced in a variety of forms, as shown in Figure 3, the body 210 having one or more mounting grooves 212 to place the disinfection water generator, the container 110 of the disinfection water generator The power supply 230 for supplying electricity required for electrolysis to the electrode 131 of the electrode, a lead wire 240 for connecting external power to the power supply, and monitoring the power supply state of the disinfectant generator and the generation state of the disinfectant; It is composed of a display adjustment unit 250 that can be adjusted.

The body 210 of the stand may be manufactured by plastic or metal plate, or may be manufactured by combining metal and plastic for each part. The upper surface of the body is formed with at least one mounting groove (212) for mounting the disinfection water generator, the bottom center of the mounting groove is provided with a socket 211 connected to the electrical supply terminal 132 of the disinfection water generator It is.

For safety, a safety switch may be installed on the bottom of the mounting groove 212. When the disinfectant generator is placed on it, the safety switch is pressed down by the weight of the disinfectant generator so that the switch is closed so that the electricity is supplied to the electrode. do. In this way, when the safety switch is used, electricity does not flow to the electrical contact of the socket 211 exposed to the outside during the use of the disinfectant generator from the stand, so that it is safe.

The body of the stand is attached to the display adjustment portion, as shown in the cross-sectional view of Figure 4, the power supply 230 is mounted therein. Since the body of the stand is not very heavy, the leg 213 can be attached to the lower part of the body, and can be moved to the required place by using the handle 214 attached to the side of the body. However, when using a large capacity canister to the sterilization water generator can be attached to the wheel instead of the leg 213 to facilitate the movement.

Power supply 230 is a function for converting the AC supplied from the outside into direct current, the function of changing the pole of the converted direct current electricity as set in the display control unit, the function to supply or cut off power to the disinfectant generator, the present disinfection water generation Each part of the device has the ability to regulate and distribute voltages and currents as needed. The power supply receives electricity from the outside through the lead wire 240.

The display adjusting unit 250 is made in the form of a panel. The display unit 251 has a concentration of disinfectant generation in the disinfectant water generator, whether or not the main power is connected, and a state of supplying electricity to the disinfectant water generator (whether electricity is supplied, supply voltage, supply current, or electrode). Other adjustment status such as electrical polarity, etc.) is displayed. In the adjusting unit 252 of the display adjusting unit, a main power switch, an electrode polarity switching interval adjusting knob, and an electrode supply electric adjusting knob are arranged. The lower surface of the display adjustment section is provided with a circuit board 253 necessary for the operation of the display adjustment section.

The display adjusting unit 250 exchanges information with the power supply 230 and displays a power supply state, and causes the power supply to supply optimal electricity to the sterilizing water generator.

The electric and signal transmission states of the power supply 230 and the display adjustment unit are as shown in FIG. 5, and can be easily manufactured by applying current electric and electronic technology.

The operation function of the electrolytic sterilizing water generator is as follows.

After filling the disinfectant generator with water and adding a small amount of salt (NaCl), put the disinfectant generator in the slot and the electrical terminal of the slot automatically comes into contact with the terminal of the disinfectant generator. DC electricity supplied from the feeder is applied. When electricity is applied to the electrode, chlorine ion (Cl-), which is an anion, is oxidized at the anode to produce chlorine (Cl), and at the cathode, sodium ions (Na +), which are cations, are reduced to free sodium (Na). This sodium reacts with water to produce sodium hydroxide and generate hydrogen. The sodium hydroxide produced at the anode reacts with chlorine produced at the cathode to produce sodium hypochlorite (NaOCl), salt (Nacl), and water (H2O).

The above chemical reactions are summarized as follows.

Anode Reaction: 2Cl ^- => Cl ₂ + 2e

Cathodic reaction: 2Na ⁺ + 2e => 2Na

2Na + 2H ₂ O => 2NaOH + H ₂

Total reaction inside the reactor: Cl ₂ + 2NaOH => NaOCl + NaCL + H ₂ O

NaOCl produced in the chemical reaction, that is, sodium hypochlorite (also called sodium hypochlorite) has a strong bactericidal action, the water of the reaction tank in which sodium hypochlorite is produced can be used as disinfectant water.

As can be seen from the above chemical formula, while the disinfectant is produced, the valve or the cock of the injector is opened (127), and various gases such as hydrogen gas, chlorine gas, and oxygen generated by electrolysis of some water to the outside are released to the outside. It is safe to let it out.

In particular, when the salt is excessively added to the disinfectant generator, a large amount of gas may occur due to a rapid chemical reaction. In addition, when an abnormality occurs in a power supply system such as a power cutoff device, electricity continues to flow through the electrode, and accordingly, a chemical reaction may be continued to generate a large amount of gas. Valves or cocks are also needed to prepare for such abnormal situations.

When sodium hypochlorite is produced to a degree sufficient for sterilization, it can be detected by a sensor to cut off the power to the electrode. The sensor may be a sensor for detecting the amount of chlorine generated during the reaction. Then, when the preset reaction time elapses, the electrolytic reaction may be stopped by a method in which power is cut off. In addition, when the reaction proceeds in the disinfectant generator, a change occurs in the current supplied to the electrode, and the power may be cut off by detecting the change in the current.

The method of using the sterilized water generated as described above is as follows. When the inside of the container 110 is pressurized by the air pump 121 of the injector 120 to the container in which the sterilized water is generated, the pressure inside the container rises above atmospheric pressure, and when the trigger 124 of the handle is pressed in this state, the nozzle 126 ), The pressurized sterilized water is sprayed through the nozzle.

The power supply 230 supplies electricity of a voltage suitable for the electrolytic reaction, and alternately supplies the polarities of electricity supplied to the electrodes of the sterilizing water generator at a time interval set by the display adjusting unit 250 or by manual operation. Electricity is supplied to the electrodes of the disinfecting water generator by alternately supplying electricity or supplying electricity without alternating electrodes. In addition, the power supply 230 serves to stop the disinfecting water generation reaction by cutting off the electricity supply to the electrode when the concentration of the disinfecting water reaches an appropriate concentration. In addition, electricity is properly supplied to other necessary parts of the apparatus.

Based on the principle as described above, the present invention electrolytic sterilizing water generating device can be used for disinfection by directly generating disinfection water in a container in a very simple manner, by directly separating the container from the stand and spraying it directly on the disinfection site.

As described above, the present inventors electrolytic sterilizing water generating device can be used for disinfection by generating the disinfecting water directly in the container in a very simple manner, by directly removing the container from the stand and spraying directly on the disinfection site.
