Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hand washing device for washing and sterilizing hands and fingers, and in particular, it relates to a hand washing device for washing and sterilizing hands and fingers. This article relates to the ozone water hand washing device used.

[Conventional technology]

In general, it is essential to frequently wash and sterilize hands and fingers when handling food or medical-related work. Conventionally, when washing hands, it was generally necessary to wash them with soap and remove dirt. The method used was to wash it away with running water such as tap water. In addition, if more reliable sterilization is required, store a disinfectant such as cresol in a basin, etc.
A common method was to dip one's fingers in it.

In addition, a method using ozone is known as having a strong sterilizing effect. For example, in Japanese Patent Publication No. 12962/1983, oxygen is ozonized using an ozonizer, the ozone gas is adsorbed on an adsorbent, and then the , an ozone water production device is shown in which the ozone gas is sucked in by a pump and dissolved in water.

Furthermore, Japanese Utility Model Application Publication No. 125399/1983 discloses an ozone water supply device in which ozone gas generated by an ozonizer is ejected into water in a water tank and dissolved in the water.

[Problem to be solved by the invention]

Since the conventional means was configured as described above, it had the following problems.

First, since soap is used by a large number of people and left in the atmosphere, it is insufficient in terms of disinfection. Also, when rinsing with tap water,
Since faucets are usually opened and closed by hand, there is a problem in that bacteria can adhere to the hands and fingers from the opening and closing process.

On the other hand, when using a disinfectant, it is necessary to replace the disinfectant periodically, but there is a question as to whether the disinfectant's sterilizing effect is maintained until the end when a large number of people use it.

Another idea is to store disinfectant in a tank and release the disinfectant from a faucet that opens when a hand approaches, but this would require a large-capacity disinfectant tank. , the equipment becomes large-scale and it becomes difficult to secure a place for installation. Furthermore, there is an economical problem in discharging a disinfectant such as cresol after one-time use. Furthermore, such disinfectants have a strong odor,
Not suitable for handling foodstuffs, etc.

In addition, there is the above-mentioned method using ozone which has a strong sterilizing effect, but ozone can be easily generated by electrolysis of pure water. Therefore, if ozone gas is generated by electrolysis of pure water and the ozone gas is dissolved in water to wash and sterilize hands, a small and economical hand washing device can be obtained. Although it is thought that washing with ozonated water leaves no odor, there is currently no such simple hand washing device that uses ozonated water. For example, the above-mentioned Japanese Patent Publication No. 60-12962 describes the production of ozonated water by converting oxygen into ozone using an ozonizer, adsorbing the ozone gas to an adsorbent, and then sucking the ozone gas using a pump and dissolving it in water. Although the device is shown, the ozonated water is used as an oxidizing agent in chemical plants such as pulp bleaching, and has an extremely high concentration, making it unsuitable for washing and sterilizing hands. Moreover, the device is extremely large-scale and cannot be installed in a washroom or the like. Also,
The above-mentioned Japanese Utility Model Application No. 61-125399 discloses an ozone water supply device in which ozone gas generated by an ozonizer is ejected into water in a water tank and dissolved in the water. The ozone gas only sterilizes the water in the water tank, and the ozone water obtained has a concentration that is drinkable, and is insufficient for washing and sterilizing hands.

The present invention was made to solve the above-mentioned problems, and in particular, ozone gas obtained by electrolyzing pure water is discharged and filled into a reaction column, and a trickle of water is discharged into the reaction column. To provide an ozonated water hand washing device in which ozonated water is obtained by contact reaction with ozone gas, and this ozonated water is released for a predetermined time from a faucet that is opened and closed by sensing the approach of a hand.

[Means to solve the problem]

The ozone water hand washing device according to the present invention includes a reaction tube;
a water sprinkler provided in the reaction cylinder and having a water sprinkling plate that supplies water fed from a water supply pipe via a water supply solenoid valve as trickle water; an ozonizer for obtaining ozone gas by electrolysis using purified water; an aeration bulb for supplying ozone gas from the ozonizer into the reaction tube; and a diffuser bulb connected to the reaction tube for supplying ozonated water to a faucet. a hand washing proximity sensor for controlling the discharge of ozonated water from the faucet, an on-off valve for the water supply solenoid valve, the operation of the liquid pump, the discharge of ozonated water from the faucet, etc. The configuration further includes an air pump connected to the reaction tube, an ozone killer provided at the top of the reaction tube, and a water level gauge provided in the reaction tube. and an ozonated water release solenoid valve provided between the liquid pump and the faucet.

[Effect]

In the ozone water hand washing device according to the present invention, a large number of trickles of water are supplied from the sprinkler plate of the water sprinkler into the reaction cylinder filled with ozone gas, so the contact area between the ozone gas and water is large, and the ozone water production efficiency is increased. The concentration of ozonated water increases significantly, and the concentration of ozonated water becomes the optimum concentration for washing and disinfecting hands.

In addition, when your hand approaches the faucet, a signal from the controller based on the signal detected by the handwash proximity sensor opens the water supply solenoid valve to generate ozone water, which is sensed by the water level gauge and is detected by the liquid pump. When the water release solenoid valve is activated, ozonated water is automatically released from the faucet for a predetermined period of time, allowing you to wash your hands without touching your toilet.

In addition, the ozone gas that is supplied into the reaction cylinder after producing and releasing a predetermined amount of ozonated water, if the hand-washing operation is not performed for a predetermined period of time, the air pump will operate for a predetermined period of time, and the ozone gas will be replaced by the air from the air pump. Therefore, it is sent from the reaction cylinder to the ozone killer,
The ozone gas concentration inside the reaction cylinder is maintained at an acceptable value by decomposing it with an ozone killer and making it harmless before releasing it to the outside of the system.

Furthermore, since the reaction tube, ozonizer, liquid pump, air pump, etc. are integrated into one unit, it is compact and can be operated simply by connecting to the water supply pipe and power supply, so you can supply ozonated water regardless of location. It can be carried out.
