Further, Japanese Patent Laid-Open No. 62-74484 describes a liquid purifying apparatus provided with ozone removing means so that harmful ozone does not remain in drinking water.

Further, Japanese Utility Model Laid-Open No. 62-50794 describes a water purifying device equipped with a bubble generating means for releasing fine bubbles containing ozone.

[Problems to be Solved by the Invention] However, the conventional water purifier described above simply adopts ozone as a sterilizing means, and the bubble generating means for performing aeration is a foam for generating fine continuous bubbles. Resin and sponge are used. There is a problem that a mere microscopic open cell can only expect a sterilizing effect by ozone, and cannot effectively decompose harmful substances such as trihalomethane and increase the amount of dissolved oxygen. That is, the present invention does not merely generate fine continuous bubbles, but generates large bubbles to extremely effectively decompose harmful substances and dramatically increase the amount of dissolved oxygen.

The drinking water purifying device described in JP-A-62-912289 discloses a device for heating or cooling drinking water aerated with ozonized gas by a temperature controller. There is no description about the mechanism for generating such large bubbles, and no description suggesting its configuration or effect is found.

And Japanese Patent Application Laid-Open No. 50-146152 describes a water purifier that utilizes the Peltier effect for cooling drinking water.
It only discloses a cooler that utilizes the Peltier effect in a water purifier, and there is no description about the mechanism that generates large bubbles like the present invention, effectively decomposes harmful substances and dissolves oxygen. It does not solve the problem of dramatically increasing the amount.

Further, Japanese Patent Application Laid-Open No. 62-74484 discloses a liquid purifying device provided with ozone removing means so that harmful ozone does not remain in drinking water. However, large bubbles as in the present invention are generated. There is no description of the mechanism.

Further, Japanese Utility Model Laid-Open No. 62-50794 describes a water purifying device equipped with a bubble generating means for releasing fine bubbles containing ozone. It is only disclosed and is different from the mechanism for generating large bubbles as in the present invention. In other words, aeration that simply generates fine bubbles
There is a problem that the amount of dissolved oxygen cannot be expected to increase, and in particular, harmful substances such as trihalomethane cannot be decomposed.

Therefore, the present invention, not only the bactericidal effect of ozone, by the mechanism of generating large bubbles, a dramatic increase in the amount of dissolved oxygen, promotes the decomposition of harmful substances such as trihalomethane, further, drinking water with improved water quality It can be stored by cooling and heating.

"Means for Solving the Problem" The present invention has been devised in view of the above problems, and a tank body for storing drinking water, an inlet for filling the tank body with drinking water, and An outlet for letting out drinking water stored in the tank body, a bubble generating means for discharging bubbles to the drinking water stored in the tank body, and a gas delivery to the bubble generating means. For supplying ozone, ozone generating means for mixing ozone into the gas supplied by the gas supplying means, ozone absorbing means inserted between the tank body and the outlet, and the tank body A heat exchanger for cooling or warming the drinking water stored in the container, the heat exchanger joining at least two kinds of different metal bodies, and a current flowing through the joining member. You can switch the direction of The gas bubble generating means is formed on at least the upper surface of the gas discharge part and the gas discharge part connected to the gas supply means. A net member, a second net member for covering at least an upper portion of the first net member, for accumulating and growing bubbles emitted from the first net member, and a second net member for covering the second net member. An outer frame member is formed, and the upper surface of the second net member is formed to have a curvature, and the bubbles accumulated and grown by the second net member are discharged near the apex. A first opening portion is provided, the upper surface portion of the outer frame member is formed to have a curvature, and near the apex, the protruding force of the accumulated and grown bubbles is increased. Is provided with a second opening for Pressure water silver lamp, and is configured so as to generate ozone and a drive means for driving the low-pressure mercury discharge lamp.

"Operation" In the present invention configured as described above, the tank body stores drinking water, the ozone generating means mixes ozone into the supply gas,
The gas supply unit can supply gas to the bubble generation unit, and the bubble generation unit can release the bubbles mixed with ozone to the drinking water. The heat exchanger cools or heats the drinking water in the tank body.

The present invention also fills the tank body with drinking water from the inlet,
The bubble generating means can discharge bubbles mixed with ozone to drinking water, the ozone absorbing means inserted between the outlet and the tank body prevents the outflow of ozone from the tank body, Further, ozone in the drinking water flowing out from the outlet can be removed. Then, when an electric current is applied to the joining member of the heat exchanger, heat is generated or absorbed by the Peltier effect at the joining portion of the two kinds of metal bodies. Further, by operating the switch member and switching the direction of the current flowing through the joining portion of the joining member, the generation and absorption of heat can be reversed, and the cooling and heating of the drinking water in the tank body can be switched.

Further, in the bubble generating means of the present invention, the gas supplied from the gas supplying means is discharged as bubbles from the first net member formed in the gas discharging portion.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, reference numeral 1 is a water quality improving apparatus main body, and water quality improving apparatus main body 1 is a tank body 2. From the bubble generating means 3, the air horn 4, the ozone generating means 5, the inflow port 6, the outflow port 7, the ozone absorbing means 8, the filter member 9, the air filter 10, and the heat exchanger 300. Has become.

As shown in FIG. 1, the water quality improvement device main body 1 has a portable pot shape including a handle 11, but can be formed in any shape. The tank body 2 stores tap water and the like, and can improve the water quality while storing. The bubble generating means 3 is for making the gas sent from the air pump 4 into bubbles and discharging the bubbles to the tap water in the tank.

Here, the bubble generating means 3 will be described in detail with reference to FIG. The bubble generating means 3 includes a hollow cylindrical member 31, a second net member 32, an outer frame body 33, a first opening 34 formed in the second net member 32, and a side wall member 35. ing. The hollow cylindrical member 31 has a plurality of holes 31 on its outer circumference.
1, 311 ... Are drilled, and a connecting portion 36 for connecting to the air pump 4 is continuously provided.
Project from the side wall member 35. Although the hollow cylindrical member 31 of the present embodiment is formed in a cylindrical shape, it is not limited to a cylindrical shape and can be formed in any shape such as a rectangular parallelepiped. Second
The net member 32 of at least covers the upper portion of the hollow cylindrical member 31 and is formed to have a curvature. A first opening 34 is formed in the second net member 32, and bubbles that have grown greatly can be discharged into water. Any material may be used for the second net member 32, but it is preferable to use stainless steel. And the second net member 32
The outer frame member 33 having the second opening 331 on the outer side of the
Are placed.

Then, the second net member 32 is housed in the outer frame member 33,
Further, the bubble generating means 3 can be assembled by housing the hollow cylindrical member 31 inside the second net member 32 and fixing the side wall member 35 to the side portion.

Next, the operation of the bubble generating means 3 will be described. The connecting portion 36 connected to the hollow cylindrical member 31 and the air pump 4 are connected by an appropriate hose member, and gas is pressure-fed from the air pump 4 to the bubble generating means 3. The gas that has entered the hollow cylindrical member 31 becomes bubbles through the plurality of holes 311, 311 ... And flows out to the outside. The size of this bubble is determined by the surface tension, the temperature, the shape of the hollow cylindrical member 31, and the like. Therefore, the size of the hole and the size of the bubble are not necessarily equal. For example, the hole 3 of the hollow cylindrical member 31
If the diameter of 11, 311 ... Is 2.5 mm, the generated bubbles will be various bubbles of about 0.1 mm to 20 mm. These bubbles reach the second net member 32 while decomposing or contacting each other and growing synthetically. If the mesh of the second net member 32 is, for example, about 2.5 to 3.0 mm,
The fine bubbles pass through the second net member 32 and float upward, but the bubbles that grow larger than the mesh stay in the second net member 32 and rise further while growing larger and rise up on the curved surface. At this time, the bubbles decompose various compounds while generating ultrasonic waves. Here, the large bubbles staying in the second net member 32 have buoyancy, but are lower than the water pressure applied to the first opening 34 (for example, about 20 mm in diameter) formed in the second net member 32. In this case, the bubbles cannot be floated upward by being pushed by the water pressure and passing through the first opening 34. However, when the bubbles grow to increase the buoyancy and exceed the water pressure applied to the first opening 34, the large bubbles pass through the openings 34 of the second net member 32 and float. At this time, the volume of the accumulated air bubbles was instantaneously changed to the first
The bubble is compressed because it is too large to pass through the opening 34 of the. Immediately after the bubbles have passed through the second net member 32, they are greatly expanded until they are balanced with the water pressure. Further, since the diameter of the first opening 34 is about 20 mm, large bubbles are momentarily subdivided, and then pass through the first opening 34 to be synthesized again to become large bubbles. At this time, the water above the large bubbles is pushed up and swirl flow occurs. The inside of the tank chamber 2 can be agitated by this swirling flow. Then, air bubbles are generated in the second opening 3 of the outer frame 33.
When passing through 31, there is an effect that the shape of the bubble is adjusted and the burst output of the bubble can be amplified.

In addition, the bubble generating means 3 of the present embodiment includes a plurality of holes 311 and
Although the hollow member 31 having 311 ...
As shown in FIG. 4, it is also possible to employ the bubble generating means 3 in which the hole members 311, 311 ... Are not formed. In the bubble generating means 3, the gas releasing part 37 has the gas releasing part 37.
The first net member 38, the second net member 32, the outer frame 33, the first opening 34 formed in the second net member 32, and the outer frame 33. And a second opening 331 formed in the outer frame 33 and a side wall member 35.

The gas discharge part 37 is connected to the air pump 4 and discharges gas into water. The gas discharge part 37 is
A hollow member having an open upper surface is sufficient, and the gas discharge portion 37 having a rectangular cross section can be used. The first net member 38 is attached to the upper opening of the gas discharge part 37 and can generate bubbles. The hole portions 311, 311 of the hollow cylindrical member 31 of the bubble generating means 3 described above.
.. fulfills the same function as. Since the first net member 38 does not need to form a hole member, there is an effect that the manufacturing cost can be reduced. The other operations are similar to those of the embodiment using the hollow cylindrical member 31, and the description thereof will be omitted.

The air pump 4 corresponds to a gas supply means and pressure-feeds the gas to the bubble generating means 3. The air pump 4 can employ an appropriate gas supply means such as a compressor. The air pump 4 requires a blowing pressure rather than a blowing amount, and a reciprocating pump is preferable to a rotary pump.

Next, the ozone generating means 5 will be described with reference to FIG.
The ozone generating means 5 comprises an ozone generating chamber 51, a quartz ultraviolet lamp 52, a stabilizer 53, and a glow lamp 54. The ozone generating chamber 51 is a sealed container, and a quartz ultraviolet lamp 52 is provided inside. Then, the ozone generating chamber 51 is provided with an inlet 55 and an outlet 5.
6 is formed, and the air blown from the inlet 55 is mixed with ozone and sent out from the outlet 56. The quartz ultraviolet lamp 52 is for generating ozone, is a low-pressure mercury discharge lamp using a transparent quartz tube as an outer tube, and emits short-wave ultraviolet rays (far ultraviolet rays) generated from the discharge of mercury vapor inside. The outer tube absorbs almost nothing, and is radiated to the outside. In particular, the quartz ultraviolet lamp 52 having a wavelength of 185 nm can generate ultraviolet rays called ozone rays 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. The drive means 200 has a function similar to that of a general fluorescent lamp, and activates the quartz ultraviolet lamp 52 and stabilizes the discharge current after activation. The quartz ultraviolet lamp 52 can be driven by using an inverter without using the glow lamp 54. The quartz ultraviolet lamp 52 has an effect that it is extremely safe because it does not generate a nitrogen compound.

The inflow port 6 is an opening for allowing tap water to flow into the tank body 2 of the water quality improvement device main body 1 after the cap member 61 is removed. A filter member 9 is inserted between the inflow port 6 and the tank body 2 to remove dust, foreign matter, etc. in tap water. A normal filter is used for the filter member 9, but a sterilizing filter may be used together. The outlet 7 releases the water stored in the tank body 2 after water quality improvement. Ozone absorbing means 8 is inserted between the outlet 7 and the tank body 2. The ozone absorbing means 8 is composed of activated carbon, absorbs ozone released from bubbles in the water, and also absorbs ozone contained in water flowing out from the outlet 7 to give a smell peculiar to ozone and dissolved ozone. Can be absorbed. Further, the ozone absorbing means 8 can prevent invasion of various bacteria and the like from the outside. The air filter 10 is inserted between the outside air and the air pump 4, and is configured so that dust and foreign matter in the air do not enter.

In addition, the water quality improvement device main body 1 of the present embodiment may have a configuration in which the tank chamber 2, the inflow port 6, and the outflow port 7 are fixed in the main body, but may also be configured to be cut off. . In this case, since the cut-off portion becomes light in weight, there is an effect that it becomes easy to carry when supplying and draining water.

Next, the heat exchanger 300 will be described with reference to FIGS. 1 and 6. The heat exchanger 300 includes an electronic refrigeration element 310, a switch means 320, a power source section 330, and a water radiator 340.
And an external radiator 350. Electronic refrigeration element 3
10 is for generating or absorbing heat by utilizing the Peltier effect. Here, with the Peltier effect, when two kinds of different metals are joined and current is applied from one end to the other end, the metal side at one end is cooled and the other end is heated. If the direction of the electric current is changed to the opposite direction, the temperature of the metal on the one end side becomes high and the temperature of the other end side becomes low. Electronic freezing is performed using this principle. In this embodiment, as shown in FIG. 6, the electronic refrigeration element 310 is composed of a P-type semiconductor 311, an N-type semiconductor 312, a first metal plate electrode 313, and a second metal plate electrode 314, 314. There is. In the present embodiment, the two different kinds of metal bodies are the P-type semiconductor 311 and the N-type semiconductor 312, but not limited to these materials, other materials can be selected. When a current is passed through the electronic refrigeration element 310, heat is generated or absorbed at the junction due to the Peltier effect. This heat absorption amount is Q = αTcI. Here, α is the sum of thermoelectric powers of two semiconductors. The electronic refrigeration element 310 is sandwiched between the water radiator 340 and the external radiator 350.

Next, the switch means 320 is for switching the direction of the current flowing through the electronic refrigeration element 310, and a switch for switching the normal power source polarity is adopted. Power supply 330
Is a normal DC power supply, and has a rectifying circuit, a smoothing circuit, etc. installed therein. It is also possible to employ a stabilized power supply.

In the heat exchanger 300 of the present embodiment configured as described above, when the switch means 320 is set to the cooling side, the electronic refrigeration element 3
10 performs an endothermic operation to cool the drinking water in the tank body 2. That is, the electronic refrigeration element 310 can take heat from the water side radiator 340 and release the heat from the external radiator 350 to the atmosphere. At the same time, since the bubble generating means 3 and the like also operate in parallel, the water temperature can be lowered while improving the water quality of drinking water. Therefore, when the water quality improvement of the drinking water in the tank body 2 is completed after a predetermined time has passed,
The water temperature also drops to an appropriate temperature, and it is possible to provide delicious drinking water that is easy to drink.

When the switch means 320 of the heat exchanger 300 is switched to the heating side, the electric current flowing through the electronic refrigeration element 310 is reversed and the electronic refrigeration element 310 performs the heating operation, and the tank body 2
Heat the drinking water in. That is, the electronic refrigeration element 310 takes heat from the external radiator 350, and this heat is absorbed by the water side radiator 340.
The drinking water in the tank body 2 can be heated by being discharged from the tank body 2. Since the heating is performed while improving the water quality of the drinking water in the same manner as the cooling operation, it is possible to obtain the drinking water having an appropriate temperature and improved water quality after a lapse of a predetermined time. The heat exchanger 300 of this embodiment does not raise the temperature to the extent that the drinking water is boiled. However, if the heated drinking water is heated by an appropriate heating means, it can be boiled in a short time and a large amount of oxygen in the water is not lost. Therefore, "hot water" having an excellent flavor can be provided, and it is most suitable for Japanese tea, black tea and the like. The electronic refrigeration element 310
It is possible to obtain drinking water of 5 to 6 ° C. during cooling operation and 60 to 70 ° C. during heating by appropriately selecting

In addition, the water quality improvement device main body 1 of the present embodiment can be equipped with a control unit such as a microcomputer.
This control unit includes a control unit 100, a mode changeover switch 110, a light receiving element 120, a reset switch 130, a timer unit 140, and a display unit 150. The mode changeover switch 110 is a switch for switching between the normal mode and the rapid mode, and when the rapid mode is set, the sterilization action almost ends (for example, 1
After the time), the end sign can be output to the display means 150. Further, when the mode is switched to the normal mode, the end sign can be output at the time when the sterilization action is sufficiently ended (for example, after 4 hours). The timer means 140 sends a control signal regarding time to the control means 100.

The water quality improving device equipped with the control unit configured as described above,
When tap water is put into the tank body 2 and attached to the water quality improvement device main body 1 and the mode changeover switch 110 is set to the normal mode, the control means 100 drives the ozone generation means 5 and controls after 4 hours from the timer means 140. When receiving the signal, the end sign can be displayed on the display means 150. Similarly, when the mode changeover switch 110 is set to the rapid mode, the control means 100 can output the end sign to the display means 150 one hour later. The timer unit 140 may be built in the control unit 100, and the control unit 100 may further include the drive unit 200.
It is also possible to adopt a configuration in which is not controlled. When tap water is replenished with the tank body 2 still attached to the water quality improvement device main body 1, it is desirable to press the reset switch 130. In this case, the count of the timer means 140 can be initialized and the time can be measured. Further, the times of the normal mode and the rapid mode can be appropriately set according to the volume of the tank body 2 and the like.

Further, the control unit of the present embodiment is equipped with a deterioration detecting function of the quartz ultraviolet lamp 52. The light receiving element 120 is provided in the ozone generating chamber 51 to receive the light beam of the quartz ultraviolet lamp 52, and to detect the light receiving element 120. The output signal is sent to the control means 100. The control means 100 judges the deterioration of the quartz ultraviolet lamp 52 from the decrease of the output signal of the light receiving element 120, and when the output signal is below a certain level, the display means 150 displays a warning prompting the replacement of the quartz ultraviolet lamp 52. can do. Further, when a plurality of quartz ultraviolet lamps 52 are mounted and the control means 100 judges that the quartz ultraviolet lamp 52 in use is deteriorated, the quartz ultraviolet lamp 5 which has not been used is automatically used.
The configuration can be switched to 2.

It is also possible to connect the switch means 320 of the heat exchanger 300 to the control means 100. If the switch means 320 is an electronic switch means composed of a power transistor or the like, the cooling / warming operation of the electronic refrigeration element 310 can be automatically switched by the control means 100. If an appropriate temperature sensor is connected to the control means 100 and the temperature inside the tank body 2 can be measured, the temperature inside the tank body 2 can be automatically controlled to an appropriate temperature.

In the present embodiment configured as described above, the air pump 4 is
The air passed by the air filter is pressure-fed to the ozone generating means 5. Here, the ozone generated by the ozone generating means 5 is mixed and sent to the bubble generating means 3. Bubbles of various sizes are generated in the bubble generating means 3, so that there is an effect that various substances can be decomposed. The large bubbles are compressed when passing through the first opening 34 of the second mesh member 32, and the gas temperature rises. And the first
After passing through the opening 34, the bubble expands again and is rapidly cooled. However, since these bubbles are generated by the volume when the temperature rises, the volume is decreased by the subsequent cooling, and the surface tension is increased. For this reason, the bubbles appear to be hard at first glance, but when the bubbles are decomposed and synthesized, ultrasonic waves with stronger energy than normal bubbles are generated. As a result, harmful substances such as chlorine and total trihalomethane can be decomposed at high speed. Here, the total trihalomethane is a general term for trihalomethane, chloroform, bromodichloromethane, dibromochloromethane, bromoform and the like. The bubbles can also dissolve a large amount of oxygen, and can increase the amount of dissolved oxygen in water. Drinking water with an increased dissolved oxygen content has a sweet taste and is easy to drink, and is optimal for watering whiskey and the like.

Although it was possible to decompose chlorine by the bubble generating means 3 to decompose carcinogens such as trihalomethane, the sterilizing action of chlorine and the like is lost, so there is concern about the propagation of various bacteria. Since ozone is contained in the ozone, ozone has a sterilizing effect and has an effect that various bacteria are not propagated. Furthermore, since ozone has a strong bleaching power and oxidizing power, it is possible to increase the decomposition rate of chlorine, carcinogens and the like. Ozone itself is unstable and changes into oxygen, which has the effect of increasing the amount of dissolved oxygen.

When the present embodiment configured as described above was tested,
As shown in the figure, the residual chlorine decreases rapidly one hour after the start of operation, and continues to decrease thereafter. Therefore, even in the 1-hour rapid mode, the residual chlorine can be reduced to half or less.
Similarly, as shown in FIG. 9, it is understood that the total amount of trihalomethanes is reduced to about half in one hour and continues to decrease thereafter.

"Effect" The present invention configured as described above has a tank body for storing drinking water, a bubble generating means for discharging bubbles to the drinking water stored in the tank body, and the bubbles. Gas supply means for delivering gas to the generation means, ozone generation means for mixing ozone into the gas supplied by the gas supply means, and cooling or adding drinking water stored in the tank body. Since it is composed of a heat exchanger for heating, the bubble generating means can decompose carcinogenic substances such as chlorine and trihalomethane, and the ozone generated from the ozone generating means can prevent the propagation of germs. In addition to that, there is an effect that the decomposition rate of chlorine and the like can be increased. Since the amount of dissolved oxygen in water can be increased by the bubble generating means and ozone, it is possible to provide high-quality water.

That is, the bubble generating means of the present invention covers the first net member for discharging bubbles and at least the upper portion of the first net member to retain and grow the bubbles discharged from the first net member. Of the second net member and an outer frame member for covering the second net member, and the upper surface portion of the second net member is formed to have a curvature and the vicinity of the apex. Since the first opening is provided in the first opening, the bubbles can be retained on the curved surface of the second net member, and when the buoyancy of the bubbles exceeds the water pressure, the bubbles are instantly opened in the first opening. Can be surfaced from. Therefore, since the bubbles are compressed when passing through the first opening and can be expanded again after passing through the first opening, there is an excellent effect that bubbles of high energy having excellent decomposition ability for chlorine and the like can be generated. Since the bubble generating means synthetically grows small bubbles to generate large bubbles, a small gas supply means is sufficient and there is an effect that energy saving can be achieved.

Since the bubble generating means employs the gas discharging portion connected to the gas supplying means and the first net member formed on at least the upper surface of the gas gunner portion, a hole for discharging bubbles is formed. Since it is not necessary to form a portion, there is an effect that the cost can be reduced. Further, the upper surface portion of the outer frame member is formed to have a curvature, and the second opening portion is formed near the apex. Because it is formed
There is an outstanding effect that it is possible to increase the burst force of large bubbles emitted from the first opening.

Since the heat exchanger of the present invention is composed of a joining member in which at least two different kinds of metal bodies are joined and a switch member for switching the direction of the current flowing through the joining member, one heat exchange is performed. There is an effect that it is possible to provide a compact drinking water quality improvement device in which a cooling device and the like can be integrated by simply switching the cooling / heating operation with a container.

Further, in the present invention, since the ozone absorbing means is inserted between the tank body and the outlet, it is possible to absorb the ozone contained in the taken out water without releasing the ozone odor to the outside. There is an effect.

Further, since the ozone generating means is composed of the low-pressure mercury discharge lamp and the driving means for driving the low-pressure mercury discharge lamp, there is an effect that it is extremely safe because it does not generate a nitrogen compound.

The heat exchanger of the present invention comprises a joining member in which at least two different kinds of metal bodies are joined, and a switch member for switching the direction of current flowing through the joining member, and is a heat exchanger utilizing the Peltier effect. The throat has an effect that it can be reduced in size and weight as a whole and can be easily integrated with a water quality improving device for drinking water. Then, the drinking water after water quality improvement is not required to be transferred to another container and stored in a refrigerator, and cooling can be performed while improving water quality, so that cooling water can be obtained quickly. It has an outstanding effect.

INDUSTRIAL APPLICABILITY Since the present invention as described above can provide drinking water in which carcinogens are decomposed, it has an outstanding effect of being able to protect the lives of infants, infants, and children, who will be particularly responsible for the next generation. Further, since cold drinking water having a large amount of dissolved oxygen and increased sweetness can be obtained, it is most suitable for watering whiskey or the like. If you wash your face with water that has a large amount of dissolved oxygen, you can activate the skin to make it look shiny and fresh, and since you can use water at an appropriate temperature, it will not leave your skin rough and be used for beauty. It's also perfect for women who make a lot of effort.
