The present invention relates to an ozone water generation device that can reduce the rate of elimination of generated ozone and thereby efficiently generate ozone water having a target ozone concentration.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional ozone water generating apparatus includes an air pump 31 that sucks in external air and forcibly sends out air, and converts oxygen in the air sent out by the air pump 31 into ozone. Ozone generator 33 having an ozone generator 32 for causing
And a control valve 37 provided on a water supply line 36 for controlling the flow of water supplied from the water source 35 to the mixing unit 34. .

When the general air is forcibly discharged from the air pump 31 and sent to the ozone generator 33, the oxygen in the air is changed to ozone by the ozone generator 33, and a part of the generated ozone is again decomposed into oxygen. And the undecomposed ozone are mixed in the mixing section 34
To be dissolved in water and turned into ozone water and discharged.

[0004]

The concentration of ozone water can be adjusted by changing the supply amount of ozone depending on the target concentration. This means that the maximum concentration of ozone water changes depending on the amount of ozone generated in the ozone generator 33. However, the heat generated around the ozone generator 32 reduces the generated ozone to oxygen again,
Reduce ozone production.

That is, a large amount of heat is simultaneously generated in the ozone generator 32 in the ozone generator 33 that converts oxygen in the air supplied by the air pump 31 into ozone, and the surrounding air is heated. Part of the ozone generated by the ozone generator 32 is instantaneously decomposed by heat instantaneously and is reduced again to oxygen. As a result, the amount of ozone entering the mixing section 34 is sharply reduced, and thus becomes much lower than the target concentration determined in consideration of the amount of ozone produced, so that the capacity of the ozone generator 32 is increased and the operation time is increased. And the efficiency of ozone water generation is reduced.

Accordingly, there is a high possibility that ozone water having a concentration lower than a predetermined concentration of ozone water will be generated, and the amount of ozone reduced by heat generated by the ozone generator 33 will vary depending on the ambient temperature conditions. However, there has been a problem that the ozone water concentration cannot be accurately calculated in consideration of the amount of ozone reduction. At the same time, the ozone generator 33
However, there is a problem that the amount of ozone generated is smaller than that of the operation amount and the efficiency is reduced.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to cool the heat generated by an ozone generator for generating ozone and prevent the decomposition of ozone to produce ozone. It is an object of the present invention to provide an ozone water generation apparatus capable of efficiently increasing the amount of ozone water at a target temperature under normal temperature conditions. It is another object of the present invention to provide an ozone water generation device that includes a turbulent flow forming unit to promote mixing of ozone and water.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings showing the embodiments. FIG. 1 is a perspective view showing an ozone water generating apparatus according to the present invention, FIG. 2 is a perspective view showing a mixing block, and FIG. 3 is a partially cutaway perspective view of the mixing block.

As shown in FIG. 1, the ozone water generating apparatus according to the present invention includes an air pump 10, an ozone generator 11 having an ozone generator 13, and a mixing section 12 for mixing water and ozone. The ozone generator 13 is housed in the mixing section 12. Therefore, the mixing unit 12 includes a mixing block 14 having an arbitrary shape in order to fix the ozone generator 13 to the mixing unit 12, and the ozone generator 13 is held on the mixing block 14. A holding portion 15 having an arbitrary shape that can be provided is provided therein. Further, the mixing block 14 includes a mixing channel 18 at a lower portion where a supply-side water pipe 16 and a discharge-side water pipe 17 connected to a water source 35 are connected, and mixes ozone generated by the ozone generator 13. An ozone supply line 20 with a check valve 19 is provided for sending out to the channel 18.

Then, the ozone generator 1 is
3 is covered with a cover 21. A gasket 22 is interposed between the cover 21 and the contact surface of the mixing block 14 to maintain airtightness, and the ozone generator 13 is fixed to the holding portion 15 in order to prevent flow after the ozone generator 13 is fixed. After being held by the holding portion 15, a support 23 made of a fixed leaf spring is mounted on the ozone generator 13. The cover 21 has an ozone discharge nozzle 24 and an air suction nozzle 25 mounted thereon.

The mixing channel 18 of the supply-side water pipe 16
A large number of balls 26,
26 are inserted, and an ozone injection nozzle 27 of the ozone supply line 20 is connected to a substantially central portion of a portion where the balls 26 are inserted.

As described above, in the ozone water generating apparatus of the present invention, the ozone generator 13 for generating ozone is used.
Is disposed in the vicinity of the mixing channel 18 through which water at normal temperature flows, so that the heat generated in the ozone generator 13 is cooled under normal temperature conditions, so that the early decomposition of ozone due to the heat can be prevented.

As shown in FIG. 1, when the external air is supplied to the mixing block 14 through the cover 21 by the air pump 10 in accordance with the control signal of the control device 28, the mixing block 14 is held in the mixing block 14, as shown in FIG. The supplied ozone generator 13 is supplied with air, and the ozone generator 13 starts operating while being supplied with electricity under the control of the control device 28 to change oxygen in the air into ozone. At this time, since the upper part of the mixing block 14 holding the ozone generator 13 is covered by the cover 21, the ozone generator 13
The ozone generated in step (1) does not flow out, and is discharged to the mixing channel 18 along the ozone supply line 20.

The ozone generator 13 is disposed above the mixing block 14, and a mixing channel 18 to which a supply water pipe 16 and an ozone water discharge water pipe 17 are connected is disposed below the ozone generator 13. Therefore, in the ozone water generation process,
The heat generated by the ozone generator 13 is water-cooled by the water flowing in the mixing channel 18, and the temperature decreases. Generally, the ozone generator 13 generates heat when converting oxygen in the air into ozone. The heat promotes the decomposition reaction of ozone and reduces it to oxygen again, so that the amount of generated ozone decreases.

The ozone generator 13 held in the holding section 15 of the mixing block 14 is exposed to the reduction due to heat generation as described above, but water flows through the mixing channel 18 provided at the closest position. Since the water flows, the temperature of the ozone generator 13 and the surrounding air is prevented from excessively rising due to the cooling reaction by the water, and the temperature is lowered, thereby preventing the already generated ozone from being decomposed by heat. As a result, the ozone already generated in the ozone generator 13 is mixed with the water in the mixing channel 18 flowing through the mixing block 14 as it is without being decomposed by heat, and is stored here and contains a large amount of ozone. Ozone water is generated.

Ozone generator 1 for mixing block 14
As shown in FIG. 3, the ozone generator 13 was first held in the holder 15 formed in the mixing block 14, and the ozone generator 13 was fixed by the support 23, as shown in FIG. Thereafter, the ozone generator 13 is mounted on the mixing block 14 with the cover 21 covered. The supply-side water pipe 16 and the discharge-side water pipe 17 are connected to both ends of the mixing flow path 18, and the cover 21 is connected to a connection portion of the supply-side water pipe 16 to the mixing flow path 18 by an ozone supply line 20, so that ozone is supplied. A check valve 19 is attached to the ozone supply line 20 so that the ozone is supplied to the supply-side water pipe 16 and a backflow is prevented. At this time, when the balls 26, 26... For forming a turbulent flow are inserted into the supply-side water pipe 16 into which ozone is introduced, the flow of water guided along the supply-side water pipe 16 is slightly broken and becomes turbulent. Instead, mixing of ozone and water is promoted, and generation of ozone water is promoted. In order to form the turbulent flow, a wing resistor or a helical resistor that is rotated forward and backward may be used instead of using the ball.

As described above, in the present invention, in order to obtain ozone water having an appropriate concentration, it is not necessary to use the ozone generator 13 having a large capacity in consideration of the amount to be thermally decomposed, and to reduce the capacity. The ozone generator 13 can be used to generate ozone water of a target concentration. In addition, by integrating the ozone generator 13 and the mixing unit 12, it is possible to realize a space design and a compact apparatus, and to simplify a manufacturing operation.

[0022]

As described in detail above, according to the ozone water generators of the first and second inventions, the ozone generator is provided in the mixing section through which the water at normal temperature flows. The heat is cooled and the decomposition of ozone is prevented. Therefore, it is not necessary to use an ozone generator having an unnecessarily large capacity, and the production of ozone water having a target concentration can be accurately adjusted according to the design capacity of the ozone generator. As a result, it is possible to increase ozone production even when a small-capacity ozone generator is used, so that under normal temperature conditions,
The target high-concentration ozone water can be efficiently generated. In addition, the integration of the ozone generator and the mixing section makes it possible to realize a compact apparatus as a whole, which leads to an improvement in production workability, thereby reducing the product cost.

According to the ozone water generating apparatus of the third and fourth aspects of the present invention, since the turbulence forming means is provided, the mixing of ozone and water is promoted, and the ozone water can be generated more efficiently. it can.
