Detailed Description of the Invention "Field of Industrial Application" The present invention relates to an ozone generator that is small and can safely generate ozonated water, and particularly relates to an ozone generator that can generate highly concentrated ozonated water. This relates to a water generator.

"Prior Art" Ozone is composed of three oxygen molecules, and its oxidizing power is the second most powerful on earth after fluorine.

Furthermore, ozone's bactericidal activity exceeds that of chlorine, so in recent years it has been used not only for water treatment, but also for wastewater treatment, food processing, air sterilization, etc. It also has excellent decolorizing power, so it is also used for water treatment. Ozone is an unstable gas and decomposes into oxygen within several tens of hours in the air and several tens of minutes in water (7). Therefore, unlike chlorine, it does not remain behind, so it is attracting attention as a promising sterilizing agent, deodorizing agent, and decolorizing agent in the future.

In addition, ozone water, which is made by dissolving ozone in water, has dissolved ozone of 1
Depending on the situation, it is used for sterilization during surgery in hospitals and for oral sterilization at dental clinics, and is also widely used for sterilization of vegetables, seafood, etc. Ozonated water is known not only for general sterilization and sterilization of Escherichia coli, but also for inactivating poliovirus and the like.

``Problems to be Solved by the Invention'' However, ozone is extremely unstable, making it impossible to store it continuously, and there is a problem in that an ozone generator must be prepared near the place of use.

Furthermore, there are ozone water generators for industrial plants, but although they are suitable for industrial use as they produce large-scale water, they have the problem of being too large and uneconomical for household use. Ta.

In addition, there are relatively small methods that perform silent discharge in oxygen-containing air, and methods that form electrodes on a ceramic layer and discharge between the creeping surfaces, but methods that perform silent discharge in air require large equipment. Because it is large-scale and expensive, it was not suitable for small-capacity household ozone generators.9 Furthermore, the method of forming electrodes on the ceramic layer and discharging between the creeping surfaces can be manufactured in a small size and at low cost. Although it is a method,
There were serious problems in that the generated capacity was small and the efficiency decreased unless the discharge surface was constantly cleaned.

In addition, due to the influence of humidity in the air, nitrogen oxides (NOx)
), and when these nitrogen oxides react with water, harmful substances such as nitrates are produced.

Therefore, there has been a strong desire for an ozonated water generator that is relatively small and capable of producing highly concentrated ozonated water.

The ozone water generation unit 1 includes a storage case 2, a bubble generation means 3, an air pump 4, an ozone generation means 5, a tank body 6, a manual pump 7, a filter member 8, and a suppression circuit 10. It consists of

The housing casing 2 houses the bubble generating means 3 and the tank body 6, and is made of a synthetic resin such as plastic or a metal material such as stainless steel.

The bubble generating means 3 is for releasing bubbles into the water stored in the tank body 6. The air pump 4 corresponds to a gas supply means, and is for delivering air mixed with ozone to the bubble generation means 3. The air pump 4 of this embodiment is composed of a motor 41, an eccentric cam 42, and a cylinder 43. When the motor 41 rotates, the eccentric cam 42 mounted on the rotating shaft of the motor 41 rotates, causing the cylinder 43 to reciprocate, so that air can be pumped. The ozone generating means 5 is
Ozone is generated using a quartz ultraviolet lamp. In this embodiment, an ozone generation chamber 51 is formed, and a quartz ultraviolet lamp is installed in the ozone generation chamber 51.

The tank body 6 is for storing liquid, and in this embodiment is configured to store tap water.

The manual pump 7 corresponds to a pump means, and the means for pumping up the ozonated water in the tank body 6 is not limited to the manual pump 7 of this embodiment, but may also be an automatic pump such as an electric pump, etc. It is also possible to use

The filter member 8 is for absorbing excess ozone released from the water surface of the tank body 6, and in this embodiment, a catalyst using activated carbon is attached to the opening 61.

The control circuit 10 includes a control section 101, a power cord 102, a switch 103, and a transformer 104.

When the motor 41 rotates and the cylinder 43 performs reciprocating motion, air is sent to the ozone generation chamber 51 through the tube 44. In the ozone generation chamber 51, ozone and air are mixed, and the mixed gas is sent to the bubble generation means 3 provided in the tank body 6 via the tube 45.

Gas containing ozone is released from the gas generating means 3, and the ozone is dissolved into the liquid.

The ozonated water in the tank body 6 can be taken out from the tip of the nozzle 71 by moving the push-down manual pump 7 up and down.

When the ionized water in the tank body 6 becomes insufficient, the lid body 62 attached to the upper part of the tank body 6 can be removed and tap water can be replenished.

Furthermore, an opening part 61 is formed in a part of the tank body 6, so that the air containing ozone that floats without being dissolved in the cleaning liquid can be released into the atmosphere.

Note that the filter member 8 attached to the open portion 61 absorbs excess ozone and prevents the peculiar depth of ozone from being diffused into the room.

Here, the bubble generating means 3 will be explained in detail based on FIG. The bubble generating means 3 includes a hollow cylindrical member 31, a net member 32, an outer frame 33, an opening 34 formed in the net member 32, and a side wall member 35. The hollow cylindrical member 31 has a plurality of holes 311, 311, . stands out from Although the hollow cylindrical member 31 of this embodiment is formed into a cylindrical shape, it is not limited to the cylindrical shape, and can be formed into any shape such as a rectangular parallelepiped. The net member 32 covers at least the upper part of the hollow cylindrical member 31 and is formed to have a curvature. Openings 34 are formed in this net member 31, allowing air bubbles that have grown large to be released into the water.

This net member 32 may be made of any material, but it is preferable to use stainless steel. An outer frame member 33 having an opening 331 is arranged outside the net member 32.

Then, by storing the net member 32 in the outer frame member 33, further storing the hollow cylindrical member 31 inside the net member 32, and fixing the side wall member 35 to the side, the bubble generating means 3 can be assembled. can.

Next, the action of this bubble generating means 3 will be explained.

A connecting portion 36 connected to the hollow cylindrical member 31 and the air pump 4 are connected by a suitable hose member, and gas is force-fed from the air pump 4 to the bubble generating means 3. The gas that has entered the hollow cylindrical member 31 flows through the plurality of holes 311, 311...
・Air bubbles form and flow out. The size of the bubbles is determined by surface tension, temperature, the shape of the hollow cylindrical member 31, etc. Therefore, the size of the hole and the size of the bubble are not necessarily equal. For example, the hollow cylindrical member 31
If the diameter of the hole portions 311, 311, etc. is 2.5 mm, the bubbles generated will vary in size from about 0.1 mm to about 20 mm. These bubbles reach the net member 32 while decomposing or coming into contact with each other and growing synthetically. The mesh of this net member 32 is, for example, 2.5 to 3.0 mm.
m, fine bubbles pass through the mesh member 32 and float upward, but bubbles that grow larger than the mesh,
It stays in the net member 32 and moves up the curved surface while growing even larger. At this time, the bubbles decompose various compounds while generating ultrasonic waves. Here, the large air bubbles staying in the net member 32 have buoyancy, but if the water pressure is lower than the water pressure applied to the opening 34 (for example, about 20M in diameter) formed in the net member 32, the air bubbles are pushed by the water pressure. It is not possible to pass through the opening 34 and float upward. however,
As the bubbles grow and their buoyancy increases and exceeds the water pressure applied to the openings 34, the large bubbles pass through the openings 34 of the net member 32 and rise to the surface. At this time, since the volume I of the remaining bubbles is too large to instantly pass through the opening 34, the bubbles are compressed. Immediately after the bubbles pass through the net member 32, they expand greatly until they are balanced with the water pressure. Further, since the opening 34 has a diameter of about 20 inches, large bubbles are instantaneously fragmented, and after passing through the opening 34 are synthesized again to become large bubbles. At this time, the water at the top of the large bubble is pushed up, creating a swirling flow. The inside of the tank chamber 2 can be stirred by this swirling flow.

When the bubble passes through the opening 331 of the outer frame 33, the shape of the bubble is adjusted and the protrusion force of the bubble can be amplified.

Note that the bubble generating means 3 of this embodiment has a plurality of holes 311.
The hollow member 31 having 311... was adopted, but
As shown in FIG. 3, it is also possible to employ a bubble generating means 3 that does not have hole members 311, 311, . . . . This bubble generating means 3 includes a gas discharge section 37 and a gas discharge section 37.
The first net member 38 formed on the upper surface of the net member 32 (
corresponding to the second net member), the outer frame 33, and the net member 3
2 and a side wall member 35. The gas discharge section 37 is connected to the air pump 4 and discharges gas into the water. The gas discharge section 37 only needs to be a hollow member having an open top surface, and the gas discharge section 37 having a rectangular cross section may also be employed. The first net member 38 is attached to the upper opening of the gas discharge section 37 and can generate air bubbles. The hole 311 of the hollow cylindrical member 31 of the bubble generating means 3.
It fulfills the same function as 311.... Since the first net member 38 does not require the formation of hole members, it has the effect of reducing manufacturing costs.

Note that the other functions are the same as those in the embodiment using the hollow cylindrical member 31, so a description thereof will be omitted.

Next, the ozone generating means 5 will be explained based on FIG. 4.

The ozone generating means 5 includes an ozone generating chamber 51, a quartz ultraviolet lamp 52, a ballast 53, and a glow lamp 54. The ozone generation chamber 51 is a sealed container, and a quartz ultraviolet lamp 52 is provided inside. This ozone generation chamber 51 has an inlet 55 and an outlet 56.
The air blown from the inlet 55 is mixed with ozone and then sent out from the outlet 56. The quartz ultraviolet lamp 52 is used to generate ozone, and is a low-pressure mercury discharge lamp that uses a transparent quartz tube for its outer bulb.The quartz ultraviolet lamp 52 is a low-pressure mercury discharge lamp that uses a transparent quartz tube for its outer bulb. The structure is such that almost no radiation is absorbed by the outer tube, and all of it is radiated to the outside. In particular, the wavelength is 1
The 85 nm quartz ultraviolet lamp 52 can generate ultraviolet rays called ozone lines that generate ozone in the air. The ballast 53 and the glow lamp 54 correspond to the driving means 200 of the low-pressure mercury discharge lamp. This driving means 2
00 works in the same way as a general fluorescent lamp, starting the quartz ultraviolet lamp 52 and stabilizing the discharge current after starting. Note that the glow lamp 54 is not used. The quartz ultraviolet lamp 52 can be driven using an inverter. The quartz ultraviolet lamp 52 does not generate nitrogen compounds, so it is extremely safe.

Next, the operation of the control circuit 10 will be explained in detail.
Since the tap water stored in the chamber contains chlorine, chloroform, trihalomethane, etc., they must be quickly removed by aeration using the bubble generating means 3. By the way, the relationship between the removal of chlorine, etc. and the air volume of the air pump 4 is as shown in FIG. Furthermore, the ozone concentration in water and the ozone concentration in gas are as shown in Figure 6. Therefore, in order to generate highly concentrated ionized water, it is necessary to generate concentrated ozone gas and send this ionized gas into the water. After starting the ozone water generation unit 1 of this embodiment, the air pump 4 sends a large amount of air to the bubble generation means 3,
Perform aeration of chlorine, etc. at high speed. At this time, the air sent from the air pump 4 passes through the ozone generation chamber 51 and is sent to the bubble generation means 3, but since the ozone generation electricity generated from the quartz ultraviolet lamp 52 is constant, the ozone concentration of the emitted air is will be lower.

Therefore, after finishing aeration with a large volume of air, it is necessary to reduce the air cap from the air pump 4 and forcefully feed the highly concentrated ozone mixed air to the bubble generating means 3. However, the motor 41 that drives the air pump 4 rotates at a constant speed, and the air volume cannot be freely adjusted. Therefore, it was decided to change the average wind I by changing the driving time of the motor 41 as shown in FIG. 7. That is, during high-speed aeration (T
In 1), the motor 41 is continuously rotated in a steady state, and during the ozonated water generation period, the motor 41 is stopped for T2, and the motor 41 is driven only for the next T3. Further, intermittent operation is performed in which the motor 41 is stopped during T2. As a result, if the air volume during rated operation (high-speed aeration) is Ql, m JI Q 2 during ozonated water generation can be expressed as follows.

(1) That is, by controlling T2 and T3, the value of Ql can be arbitrarily set.9 In this embodiment, HIN', 1
The microcomputer o1 is configured to maintain an appropriate Ql by controlling the motor 41.

Therefore, the ozonated water generation unit 1 of this embodiment has a configuration in which air containing ozone is dissolved into the cleaning water by the bubble generation means 3, so that residual chlorine, trihalomethane, etc. in tap water can be removed. A further advantage is that water sterilized by ozone can be used. Ozonated water is used to treat skin diseases, the circulatory system, and hemorrhoids, and can be said to be the safest and most suitable cleaning solution for facial cleansing and the like.

Ozone quickly dissolves in water and turns into oxygen, so there is no need to worry about harmful residues being produced. Furthermore, ozone has the property of dissolving into water several times more than oxygen. Therefore, the activated high oxygen water has the effect of activating the skin of the human body.

In this embodiment, the air pump 4 operates continuously during aeration to decompose chlorine, etc., and the air pump 4 operates intermittently during ozonated water generation, so that chlorine, etc. can be decomposed at high speed, and high concentrations can be achieved. It has the effect of being able to generate ozonated water.

"Effects" The present invention configured as described above includes a tank body for storing a liquid, a bubble generating means for releasing bubbles into the liquid stored in the tank body, and a bubble generating means for discharging bubbles into the liquid stored in the tank body. The tank body is composed of a gas supply means for sending gas to the tank body, and an ozone generation means for mixing ozone into the gas supplied by the gas supply means, and is used for taking out the liquid stored in the tank body. Since it is equipped with a pump means, it is possible to remove residual chlorine, trihalomethane, etc. from the liquid, and furthermore, it has the advantage that it can be used for cleaning water that has been sterilized by ozone. Ozonated water is also used to treat skin diseases, the circulatory system, and hemorrhoids, so it is the safest and most suitable facial wash. Furthermore, since ozone quickly dissolves in water and changes into oxygen, there is no need to worry about the generation of harmful residues, and the activated high-oxygen water can revitalize the human skin. Since a filter member for absorbing excess ozone can be formed in the upper part of the tank body, the odor peculiar to ozone does not fill the room9. Since it is made of activated carbon and a pressurized manual pump can be used as the pump means, it is possible to provide a compact and simple ozonated water generator.

The present invention also provides a tank body for storing a liquid, a bubble generating means for releasing bubbles into the liquid stored in the tank body, and a bubble generating means for delivering gas to the bubble generating means. The gas supply means includes a gas supply means and an ozone generation means for mixing ozone into the gas supplied by the gas supply means, and the gas supply means includes a gas pressure feeding means and a driving means for driving the gas pressure feeding means. Since the driving means can be configured to be capable of intermittent operation, the gas supply means operates continuously during aeration to decompose chlorine, etc., and the gas supply means operates intermittently during ozonated water generation. It has the outstanding effect of being able to rapidly decompose chlorine and other substances, as well as producing highly concentrated ozone water.

Further, the bubble generating means of the present invention includes a hollow member having a plurality of holes for connecting the gas supply means, and a net member that covers at least the upper part of the hollow member, and the net member has a curvature. Since the mesh member is formed with an opening, the air bubbles can be retained on the curvature surface of the net member, and when the buoyant force of the air bubble exceeds the water pressure, the air bubble instantly floats up from the opening. can be done. Therefore, the bubbles are compressed when they pass through the opening, and can be expanded again after passing through the opening, resulting in the outstanding effect of generating high-energy bubbles with excellent decomposition ability for chlorine, etc. In this method, small bubbles are synthetically grown to generate large bubbles, so a small gas supply means is sufficient, and energy saving can be achieved.

Furthermore, the bubble generating means of the present invention includes a gas discharge section for connection to the gas supply means, a plate member formed at least on the upper surface of the gas discharge section and having a curvature, and an opening formed in the plate member. and installed along this plate member,
Since the air bubble generating means is composed of a net member that covers at least the opening, a curved surface portion can be formed by simply attaching the net member along the plate member, and a bubble generating means that is simple in structure and inexpensive can be provided.

Further, since the ozone generating means of the present invention is composed of a low-pressure mercury discharge lamp and a driving means for driving the low-pressure mercury discharge lamp, the ozone generating means of the present invention does not generate harmful nitrogen oxides and can easily generate ozone water. This has the advantage of being able to provide a generator.

The ozonated water produced by the present invention as described above can activate the skin, and is therefore most suitable as a facial cleanser for women. Furthermore, ozonated water is effective in cleaning and sterilizing the skin, sterilizing the mouth by gargling, and reducing bad breath.
