い。Generally, ozone water is produced by dissolving ozone in water by an ozone generator, but since the amount of ozone generated in the ozone generator is extremely small, it is generated in this ozone generator. In the method in which ozone is continuously mixed with continuously flowing water, ozone water having a predetermined ozone concentration cannot be obtained unless the flow rate of water per unit time is extremely small.

る。Therefore, conventionally, as shown in FIG. 2, between the tank 1 containing water and the pump 2, a circulation pipe for pumping the water in the tank 1 by the pump 2 and then returning it back into the tank. A channel 3 is formed, and an ozone generator 4 is formed in the circulation channel 3.
The ejector 5 adapted to suck in the ozone generated in the step 1 is provided, and the ozone in the tank 1 is dissolved in the circulating water to make the water in the tank 1 ozone water having a predetermined ozone concentration.
The ozone water is supplied from the branch pipe 7 to the place where the ozone water is used by closing the valve 6 in the circulation pipe 3 and opening the valve 8 in the branch pipe 7. .

大幅にアップするのであった。Therefore, in this conventional ozone water producing apparatus, the tank 1 for storing a certain amount of water and the pump 2 for circulating the water in the tank 1 are required, so that the apparatus becomes significantly large and However, the device became extremely heavy, and the price increased significantly.
本考案は、これらの問題を解消することを技術的課題

た。The inventor is supposed to store water in the tank,
Although the above-mentioned problems are brought about, the present invention has been completed by focusing on the fact that the ozone generator can be made to store ozone and the device can be made smaller and lighter.

を設けることを要旨とするものである。That is, according to the present invention, an ejector having an ozone inlet is provided in the middle of a water supply pipe from a water supply source to a place where ozone water is used, while an ozone supply pipe from an ozone generator to the inlet of the ejector is provided. In the middle of the passage, an ozone reservoir portion made of a pipe material of appropriate length is provided, and further, in the ozone supply passage, an air introduction pipe passage having an opening / closing valve at a site upstream of the ozone reservoir portion is provided. , An air vent pipe is connected to a site on the downstream side of the ozone reservoir, and the ozone vent pipe is cut off at the connection part of the air vent pipe to the ozone feed pipe to block the ozone vent pipe. The gist of the present invention is to provide a switching valve for selectively switching between a state in which the ozone storage unit communicates with a state in which the ozone reservoir communicates with the air vent pipe.

られる。In this configuration, when the on-off valve in the air introduction conduit for the ozone supply conduit is closed and the switching valve for the air vent conduit is switched to a state in which the ozone reservoir is in communication with the air vent conduit, ozone from the ozone generator is removed. The air in the ozone reservoir provided in the middle of the ozone supply conduit is stored in the ozone reservoir while being pushed out from the air vent conduit.

されるのである。Then, when ozone is stored in the ozone reservoir to a state where ozone flows out from the air vent pipe,
While opening the on-off valve in the air introduction pipe, switch the switching valve for the air vent pipe to the state where the air vent pipe is closed and the ozone supply pipe is in communication, and then supply water to the ejector in the water supply pipe. By supplying water from a source, a suction negative pressure in the ejector acts on the ozone reservoir, and the ozone in the ozone reservoir is supplied to the ejector from the air introduction conduit in the ozone reservoir. Since air is sucked in while being introduced, ozone water in which ozone is dissolved is discharged from the ejection port of the ejector.

え操作して、オゾン溜部内にオゾンを溜ると言うよう
に、以下、前記操作を繰り返すことにより、オゾン水を
間欠的に製造することができるのである。In this way, when the ozone in the ozone reservoir is exhausted, the supply of water to the ejector is stopped, the on-off valve in the air introduction pipe is closed, and the switching valve is connected to the ozone reservoir in the air vent pipe. It is possible to intermittently produce ozone water by repeating the above-mentioned operation so that the ozone is stored in the ozone storage portion by switching to the state.

とができない。In this case, if the ozone reservoir is a tank type having an appropriate internal volume, when the ozone from the ozone generator is introduced into the tank type ozone reservoir, the ozone will be the tank type ozone. By mixing with the air in the reservoir, ozone cannot be stored in a high concentration state in the ozone reservoir, and when the air from the air introduction pipe is introduced into the ozone reservoir, this air Is mixed with ozone in the ozone reservoir,
Since the concentration of ozone sucked into the ejector decreases, it is impossible to produce ozone water having a predetermined ozone concentration.

けるオゾンを順次押し出すことにより、エゼクターに対
して高い濃度のオゾンを供給できるから、オゾン水にお
けるオゾン濃度を所定値にすることができるのである。On the other hand, according to the present invention, the ozone reservoir is made of a pipe material having an appropriate length. With this configuration, the ozone from the ozone generator is stored in the ozone reservoir, Since the air in the air flows in while pushing out from the air vent pipe and replaces the air, it is possible to store ozone in a high concentration state in the ozone reservoir, and moreover, the air from the air introduction pipe in the ozone reservoir. When ozone is introduced, ozone in a high concentration can be supplied to the ejector by sequentially pushing out ozone in the ozone reservoir with this air, so that the ozone concentration in the ozone water can be set to a predetermined value.
また、前記エゼクターへの水の供給量を一定にした場
合において、前記空気導入管路からの空気の導入量を増
減調節することにより、オゾン水におけるオゾン濃度
を、任意に調節できるのである。Further, when the amount of water supplied to the ejector is constant, the ozone concentration in the ozone water can be arbitrarily adjusted by increasing or decreasing the amount of air introduced from the air introducing pipe.
従って、本考案によると、前記従来のように、適宣量
の水を蓄えるためのタンクを必要とすることなく、所定
のオゾン濃度のオゾン水を確実に製造することができる
から、オゾン水の製造装置を著しく小型・軽量化できる
と共に、安価に提供することができる効果を有する。Therefore, according to the present invention, it is possible to reliably produce ozone water having a predetermined ozone concentration without the need for a tank for storing a proper amount of water as in the conventional case. The manufacturing apparatus can be remarkably reduced in size and weight and can be provided at low cost.

One or both of the open / close valves 25b in FIG. 2 are opened, while the three-way switching valve 28 for the air vent pipe 27 is closed, and the air vent pipe 27 is closed to supply the ozone supply pipe 22.
, The water supply valve 19 is opened, and a fixed amount of tap water is supplied to the ejector 21, whereby the ozone reservoir 23 is supplied with the ejector.
The suction negative pressure in 21 acts and the ozone in the ozone reservoir 23 is transferred to the ejector 21.
Since the air is sucked while introducing air from either one or both of the first air introducing pipe 24 and the second air introducing pipe 25 into the inside 23, ozone water in which ozone is dissolved is discharged from the discharge port of the ejector 21. It is done.

If it is set to be high and the air is introduced only from the first air introduction conduit 24, the ozone concentration in the ozone water becomes a medium concentration, and furthermore, the air is introduced only from the second air introduction conduit 25. If it is set so that the ozone concentration in the ozone water becomes low, it is possible to arbitrarily adjust the ozone concentration in the ozone water by increasing or decreasing the amount of air introduced into the ozone reservoir 23.
