られ難い等で問題も多い。This is unhygienic and causes microorganisms in the water to be dispersed during earthquakes and humidification, causing infections. This point is described in the book titled: Antibacterial and Antifungal (Vol. 16.Nα91988.P2O3). In addition, the inside of the humidifier tank becomes dirty due to the proliferation of microorganisms, and there are also negative effects such as dust scattering due to the eruption of inorganic substances such as calcium and magnesium contained in the water. Therefore,
As in Japanese Utility Model Publication No. 61-33457, measures were taken to dissolve silver ion electrodes etc. with electric current so that silver ions having a sterilizing effect were contained in the water;
It has been proposed, as in Publication No. 6, to sterilize germs by mixing or applying a bactericide or an anti-inflammatory agent to the constituent materials of a humidifier. However, these methods have not yet been put into practical use, and it is difficult to ensure their effectiveness and sustainability, and even if they are effective, they may deteriorate or deteriorate over time.
There are problems such as wear and tear. In addition, for dust and dirt, the use of ion exchange resins has been proposed as shown in Utility Model Publications No. 143-1982 and Publication No. 5553-1983, but these are expensive, have complicated structures, and There are many problems such as difficulty in obtaining sufficient effects.

などの手入れはなされていないことが多い。(c) Problems to be Solved by the Invention As mentioned above, in ultrasonic humidifiers, the water stored in the water supply tank and water tank is easily contaminated with microorganisms such as bacteria. Therefore, in order to prevent this, clean processing such as washing must be performed at all times. Additionally, if water is left standing, microorganisms will breed, so it is necessary to drain the water when the equipment is stopped. However, in reality, cleaning, draining, and other maintenance are often not done.

状に器内に付着したり、加湿時に粉塵として飛散する。In addition, these aquariums and water supply tanks that are contaminated with microorganisms are difficult to clean, requiring a great deal of effort, and because they are structurally complex, some parts are difficult to clean with a brush or the like. In addition, water contains inorganic substances such as calcium and magnesium, which become white powder and adhere to the interior of the container as scales, or scatter as dust during humidification.

とした加湿器を提供することを目的とする。The present invention solves these problems from a viewpoint that is significantly different from the conventional technology described above, and ensures that the humidifying water is sterilized, is sanitary without the scattering of microorganisms, and also prevents inorganic components from adhering to the inner surface of the aquarium. It is an object of the present invention to provide a humidifier that prevents such problems as much as possible and is easy to clean and remove.

のである。(d) Means for Solving the Problems In order to achieve the above object, the present invention provides a water tank equipped with an atomizing means such as an ultrasonic vibrator, a water supply tank for supplying water to this water tank, and a water tank and a water supply tank. In a humidifier consisting of a humidifier body equipped with a tank, one or more pairs of insoluble or highly corrosion-resistant electrodes are placed in the water supply tank or water tank so as to be in contact with water, and a DC component is applied to the electrodes to generate electricity. It decomposes chlorine ions in the water and converts them into chlorine, so that chlorine is continuously generated and replenished in the water.

含まれている。(e) Function When electrolysis is performed using a titanium electrode coated with a precious metal, oxygen and chlorine are generated at the anode, and hydrogen is generated at the cathode. By the way, water generally contains soluble substances such as sulfate ions, nitrate ions, chloride ions, sodium ions, magnesium ions, and calcium ions.

す。Therefore, the chlorine generated here is the result of conversion of chlorine ions in the water by electrolysis, and this chlorine immediately dissolves in the water and acts as a strong oxidizing agent in the form of hypochlorite ions (CIO'-), which removes organic substances. It causes decomposition, precipitation, bactericidal action, etc.

はな(なる。また、有機物質などは塩素の強い酸化力に
より酸化。In addition, scale components consisting of inorganic substances such as magnesium and calcium are deposited and precipitated on the cathode. Therefore, the sterilizing effect of chlorine suppresses the proliferation of microorganisms, eliminating the scattering of microorganisms and solving problems such as infections. Substances are oxidized due to the strong oxidizing power of chlorine.
分解され水中に浮遊して付着しない。更に、スケール分

、粉塵として飛散されず加湿蒸気のあたる部分の白化の
防止にも役立つ。It decomposes and floats in water and does not stick to it. Furthermore, since scale deposits near the electrodes, removing it here will prevent it from being scattered as dust and will help prevent whitening of areas exposed to humidified steam.
(へ)実施例 以下1本発明の実施例を図面に基づいて説明する。(f) Example An embodiment of the present invention will be described below based on the drawings.

The valve body 6 is pushed up by the protrusion 8 on the side of the main body 1, opening the water supply lower and making it possible to supply water to the water tank 2. 9,9
are a pair of insoluble or highly corrosion-resistant electrodes attached to the water supply tank 4 side of the water tank 2; for example, a ferrite electrode or a titanium electrode coated with a noble metal is used. Although it is provided in the water tank 2 in the embodiment, the water supply tank 4
may be provided. Moreover, there is no problem in providing one or more pairs. A power source section consisting of a power transformer (see FIG. 2) and a rectifier circuit (not shown) arranged in the active device chamber 10 on the right side of the main body 1 is connected to the electrodes 9, 9.
A direct current flows between the picture electrodes 9, 9. As a result, aquarium 2
The water inside is electrolyzed. That is, oxygen is generated at the anode and hydrogen is generated at the cathode, and these are released into the atmosphere. In addition, chlorine (C12) is generated at the anode. This is because natural water generally always contains some chlorine ions.
Furthermore, since the chlorine agent injected for disinfection and sterilization is reduced in drinking water, chlorine ions usually exist in the range of several ppm to several tens of ppm. Therefore, by flowing a direct current between the anode and the cathode immersed in water, chlorine ions are oxidized at the anode and chlorine gas (C1,) is generated.

とも可能である。22 is a DC constant current power supply for keeping the current value flowing through the electrodes 9, 9 constant, and 23 is a polarity switching circuit for switching the polarity of the electrodes at predetermined time intervals to prevent scale from adhering to the electrodes due to continuous energization. 2 indicates a water tank in which a pair of electrodes 9, 9 are arranged. Here, the DC constant current power supply 22 is for supplying a current of more than a certain value necessary for stable generation of chlorine, and outputs a constant current. However, since the amount of chlorine generated varies depending on the water quality, the current value can be increased or decreased accordingly. In order to prevent scale from adhering to the electrodes, the polarity switching circuit 23 needs to switch the polarity within the shortest time set in advance in the case of continuous energization. This is handled by switching over a considerably longer period of time. Regarding timer 21, the energization time timer is set to 1 depending on the chlorine ion concentration of the water quality.
This adjusts the energization time, and the amount of chlorine generated is naturally proportional to the amount of electricity (current x time), so in order to obtain a stable chlorine amount, it is necessary to control the energization for a predetermined period of time.
Furthermore, due to variations in water quality (chlorine ion concentration), it is necessary to adjust and set the appropriate energization time. Note that by changing the current value, it is also possible to control the amount of electricity and adjust the amount of chlorine.

易化、検知作動の信頼性を上げることができる。The following energization time interval timer replenishes the generated chlorine as it is consumed by reducing substances and atmospheric dissipation over time.
Set so that the power is turned on again. In addition, safety devices should be installed to prevent overcurrent, overvoltage, and abnormal energization, so that abnormalities in the circuit can be confirmed, and in the event of a failure, the energization to the electrodes should be cut off. to ensure safety. In this case, when the water tank 2 runs out of water, the water level is determined by detecting the change in resistance value between the electrodes 9, 9 so that the current is not turned on. Similarly, the electrode 9.9 can be used to construct a circuit that cuts off the water in the water tank 2, or to construct a notification circuit that notifies replenishment when the water in the water tank 2 becomes low. In this way, the water level is detected from the resistance value to water level changes of the electrodes 9, 9 provided for electrolysis, which eliminates the need for water level detection with a proximity switch using a float, etc., and simplifies the configuration and increases the reliability of the detection operation. You can improve your sexuality.
次に上記構成において、その作用を説明する。Next, the operation of the above configuration will be explained.
加湿器本体1に給水タンク4をセットし、そのセット時
に開放する給水口4を介して水槽2に給水が成される。A water supply tank 4 is set in a humidifier main body 1, and water is supplied to a water tank 2 through a water supply port 4 that is opened when the humidifier body 1 is set.

、水槽2内の電極9,9には第2図の電解用電源回路に
より、直流電流が流されて、中の水は電気分解される。When the humidifier is connected to an AC 100V power source and driven, the ultrasonic vibrator 5 vibrates, and the water in the water tank 2 becomes an aerosol with a particle size of several microns and is dispersed from the spray nozzle 13. On the other hand, a direct current is passed through the electrodes 9, 9 in the water tank 2 by the electrolysis power supply circuit shown in FIG. 2, and the water therein is electrolyzed.

ところで、発生した塩素ガス(ciz)は水中に溶けて
、次亜塩素酸(ucao)を生成し、遊離残留塩素の形
で殺菌作用をもたらす。By the way, the generated chlorine gas (ciz) dissolves in water to produce hypochlorous acid (ucao), which provides a sterilizing effect in the form of free residual chlorine.

) This hypochlorous acid (HClO) further undergoes the following change,
HCl0→H"+C10-... (3) The state becomes hypochlorite ion (cio). This hypochlorite ion (C
tO) has a very strong oxidizing power, so it quickly destroys bacteria in the water.
Alternatively, it oxidizes dirt and other substances and converts itself into chlorine ions.

この遊離残留塩素は、塩素イオンにかえる。This oxidation has a bactericidal effect and a scale precipitation effect. This prevents microbial contamination of the water in the water tank 2, and also allows inorganic substances dissolved in the water to be precipitated and removed. After oxidation, this free residual chlorine is converted into chlorine ions.

、衛生的な使用を可能とする加湿器となる。Therefore, chlorine ions in water are converted to chlorine by electrolysis, and chlorine can be continuously generated to replenish the amount consumed by sterilization, etc., and chlorine is always left in the water in the aquarium 2. This prevents the growth of microorganisms. Therefore, the dispersion of bacteria contained in the aerosol is prevented, which prevents infections and the like, resulting in a humidifier that can be used in a sanitary manner.

This will be better understood through experimental results showing the relationship between the residual chlorine in the atmosphere and the number of bacteria in the atmosphere at the time of the eruption. In the diagram, "start" and "replacement" are written immediately after the power is turned on.
Or, it indicates immediately after replacing the water. In other words, this measurement method collects and measures general bacteria that are sprayed for 1 minute in a humidified state, and the water used has been stagnant in the water tank for more than 1 day. When we actually checked this water using the device of the present invention, we found that if no chlorine was detected, a large amount of bacteria was being released, but when chlorine was present, the number of bacteria decreased drastically and disappeared. It was found that the method was effective, and as long as 0.2 ppm of residual chlorine was present, no general bacteria were detected.

Therefore, by removing these, inorganic substances are no longer contained in the aerosol and dissipated, and the problem of dust can be solved.
2)加湿器の清浄、洗浄が容易になる。2) It becomes easier to clean and wash the humidifier.

In addition, there is no stubborn adhesion to the aquarium wall due to oxidation of organic substances such as dirt.
It can be easily cleaned. The polarity switching circuit 23 is operated in order to prevent scale from depositing on the electrodes due to the action of 1), which would cause a loss of good current conduction and conversely impair chlorine generation.
