Description

  The present invention relates to an ozone water generator installed in a water supply line, and relates to an ozone water generator for supplying water that has passed through the equipment as ozone water from a line terminal as ozone water.

  At present, there are many types of ozone water generators that can be attached to the stopcocks, but there is no type installed on the water line.

  A possible reason for this is that the effectiveness of ozone water has been recognized in recent years, and an ozone water generator that can be attached to a stop cock of a terminal has emerged. .

  When connected to a water supply line, the electrolytic type will end up with limited ozone concentration and water volume in the capacity of the equipment. In the ozone gas ejector type, when ozone gas is mixed with water on the line, if the terminal faucet is closed from the ozone gas introduction hole for the ejector part, the technical problem that water on the line flows in due to water pressure will be overcome. There was a need.

However, considering the effectiveness of ozone water, it is not denied that an ozone water generator is attached to each individual stop cock, but when installed on the water line, supply of ozone water from all terminal stop cocks By devising a device that can receive water, all the water discharged from each faucet can be easily used as domestic water or industrial water, so that it can contribute to the demands of various areas.
Patent Publication 2003-320232 Patent Publication 2005-169297 Japan Ozone Association publication

  In this case, since the equipment is installed on the water line, there is of course a constant water pressure when the terminal stop cock is closed, and tap water flows into the equipment of the ozone water generator. It is necessary to have.

  A method that can be employed relatively easily is an electrolyzed ozone water generator. With this method, even if a high water pressure of about 10 Mpa is applied to the ozone water generator, the ozone water generator is not damaged at all, and the water passing through the vessel can be electrically decomposed to generate ozone water. I can do it. However, in the case of the electrolytic type, the target ozone water concentration cannot be obtained unless the amount of water is remarkably reduced in consideration of the mutual relationship between the water flow rate and the electrolysis capability, although it depends on the apparatus capability.

  On the other hand, in a device that generates ozone water by mixing ozone gas generated by gas phase discharge into water, a hole is usually provided in a water pipe that has a structure that generates negative pressure due to the flow of water, and ozone gas is introduced into the hole. In the so-called ejector method that generates ozone water by sucking ozone gas into the water pipe by the negative pressure generated when the water flows through the water pipe, when the water flow is cut off by the terminal stop cock, the water pressure is applied to the equipment and the tap water However, it goes to the ozone gas introduction hole (1) of the ejector section and flows into the ozone gas generator, and the equipment is damaged.

  Therefore, in the case of an electrolytic ozone water generator among the products concerned, the influence of water pressure is avoided by using normal ozone-resistant packing for the joints between the components of the instrument and the tap water contact parts. It is easy to take measures against water leakage. The concentration and amount of ozone water can be solved by installing a combination of multiple units.

  On the other hand, methods for producing ozone gas when using ozone generated by gas-phase discharge, methods for mixing ozone and water, etc. have already been filed “Japanese Patent Application Nos. 2003-414419”, “2004-338664”, “PCТ / JP2006 / 319934”. It can be easily solved by using multiple technologies. However, the ejector method is very troublesome with the device of the present invention connected to the water line. When the terminal faucet is released, ozone gas is sucked in along with the water flow, and when the terminal faucet is closed, the ejector hole (1) for guiding the ozone gas to the line must be mechanically closed completely in an instant. Therefore, the device may have a structure similar to that of “Japanese Patent Application No. 2006-332721” for which a patent application has already been filed, but a stainless steel bulb (2) that closes the ozone gas introduction hole in the ejector portion, and a resilient shield ring that receives the stainless steel ball ( 3) When the terminal stop cock is closed, the problem can be solved by providing a spring (4) for instantaneously moving the stainless steel bulb and tightly sealing the shield ring.

  Since the present invention can be incorporated into a water supply line, ozone water is generated in a concentrated manner, and when each terminal stop cock is released, ozone water can be used from all terminal stop cocks, so the sterilization action by ozone is easy. A hygienic living environment can be constructed. Or it can be used as a wide range of industrial water.

  The biggest problem in the case of the electrolytic method is that the required water amount corresponding to the required ozone water concentration cannot be obtained, and the equipment configuration for ensuring the satisfactory ozone water concentration and water amount was considered.

  In the case of generating ozone water by mixing ozone gas generated by gas phase discharge into water, prevention of inflow water from the ejector hole that guides ozone gas to the line and consideration of ozone water concentration and water volume securing as in the case of electrolytic type did.

  In the case of the electrolytic type, the present invention is to use a plurality of small devices. First, to increase the concentration of ozone water, as shown in 1 of 3 of FIG. It solves by doing. Securing the amount of water can be solved by arranging the same device on the line in parallel as shown by 3-2 in Fig. (3). Furthermore, in installing the vessel, it becomes more effective by adding a water softening device on the water line before the installation of the vessel in order to fully demonstrate the capability of the vessel.

In the case of generating ozone water by mixing ozone gas generated by gas phase discharge with water, the water pressure is generated by shutting off the water supply with the terminal stop cock, so the ejector part ozone gas introduction hole (1) is instantaneous and perfect. Therefore, as shown in Figure (1), the stainless steel sphere (2), the elastic shield ring (3) that receives the stainless steel sphere, and when the terminal stop cock is closed, the stainless steel sphere is moved momentarily and the shield ring This can be solved by providing a spring (4) for tightly sealing to the seal.

  Next, when the terminal stop cock is released, a negative pressure is generated along with the water flow in the ejector section, and the stainless steel bulb (2), which is in close contact with the shield ring (3) by the spring (4), sucks ozone gas by contraction of the spring. Tap water and ozone are mixed on the line and discharged from the stop cock, and can be used as ozone water.

  As shown by the cross-sectional view of Fig. (1), the ozone gas is sealed with a stainless steel bulb (3) that is in close contact with the shield ring (3) by a spring (4). When flowing from the direction (B) to the direction (C), negative pressure is generated at the ejector nozzle (5), and the pressing force of the pulling (4) is repelled, resulting in a gap between the stainless ball (2) and the shield ring (3) (A) Water and ozone are simultaneously injected and mixed at the tip of the ejector nozzle (5) from the direction into the (C) direction line.

  In the case of generating ozone water by mixing ozone gas generated by gas phase discharge with water, nitrogen oxide is also generated as a by-product at the same time to generate ozone gas in the air raw material, so a device to remove with catalyst etc. is implemented Doing so constitutes a better device.

  In the case of generating ozone water by mixing ozone gas generated by gas phase discharge into water, the best ozone water to be obtained can be obtained by installing the device in series and in parallel as in the electrolytic method.

Based on the above configuration, the present invention can be performed with an ozone water generator attached to a conventional line terminal. As one of the types, the type attached to each stop cock is limited and the amount of water is limited, and the ozone concentration is limited to the capacity of the equipment attached to the stop cock. It became possible to remove these obstacles. Regarding the amount of water, since the device is attached to the line, the device is not attached to the end of the terminal stop cock, so there is no barrier after the stop cock is released, so the amount of water can be secured. If the amount of water decreases due to the resistance of the product of the present invention mounted on the line, it is possible to secure the amount of water by arranging the devices in parallel along the line. Similarly, in the case of ozone concentration 2 in the case where high concentration ozone water is required, naturally, when it is attached to a stop cock, only ozone water having an ozone concentration limited to the capability of the device is used. I can't get it. Here, the ozone concentration in the case of the line mounting type of the present invention can obtain ozone water having the concentration required by installing the devices in series. Therefore, a large amount of water is required and management of the ozone concentration is required. For example, it can be used for a wide range of applications such as cleaning of swimming pool water, cleaning of harvested vegetables, cleaning of large baths, and cleaning of livestock farms.
