Description

Detailed Description of the Invention "Industrial Application Field" The present invention decomposes harmful substances such as chlorine and trihalomethane contained in tap water, and also prevents the proliferation of general bacteria by providing ozone generation means. It relates to a water quality improvement device for drinking water that can increase the amount of dissolved oxygen using a bubble generation means and an ozone generation means, and is particularly equipped with a heat exchanger that utilizes the Beltier effect to improve the water quality of stored drinking water. This is an inspiration for a device that can improve the quality of drinking water by cooling and heating it while improving it.

"Conventional technology j As is well known, tap water is mixed with chlorine for sterilization. Sterilization using chlorine has made a great contribution to the prevention of infectious diseases since the war. However, It has become clear that this chlorine reacts chemically with the natural humic acids contained in the raw water taken, producing carcinogens such as 1-rehalomethane.In particular, the impact on infants is a serious problem. Therefore, it is recommended that the water used for powdered milk be boiled and then cooled before use.

Therefore, various water treatment devices such as water purifiers have been developed.

General water purifiers for home use include types that use filters such as microfilters to remove dirt and germs, and types that use ion exchangers to increase ions in the water.
Although there are some types that use a combination of both, most water purifiers are based on a one-time filter system. There were two types of installation methods: a direct-to-faucet type that was installed directly on the water faucet, and an installation type that was installed in another location.

However, one of the conventional methods described above, which involves boiling the tap water and using the cooled water, requires time and effort to boil and cool the water, and the cooling water cannot be expected to have the sterilizing effect of chlorine, so it is free from harmful bacteria. There was a problem that the bacteria would propagate.9Therefore, it had to be used immediately with cooled water, making handling extremely troublesome.

Furthermore, filter-type water purifiers, which are the other type of conventional water purifiers, are fast-acting and effective in removing dust and foreign substances, but they also remove chlorine for sterilization, which can lead to the growth of bacteria in the filtered water. The problem was that it was extremely unsanitary. Furthermore, filter-type water purifiers do not eliminate germs and trihalomethane themselves, but instead adsorb them to the filter, so if you reuse them after not using them for a long time, there is a serious problem that the germs that have grown will flow out. In addition, filter type water purifiers had to be replaced frequently because the filter part became contaminated with use.

However, in a water purifier, the filter portion accounts for most of the cost of the water purifier, and there is a problem in that the replacement cost becomes extremely high. The timing of replacement is generally left to the user's discretion, and it has been difficult to determine the timing of replacement. Regarding the removal of organic compounds, although it is effective immediately after installation,
There was a problem in that the effect would be lost even if the amount was reduced to about 10%.

The water purifiers that connect directly to the faucet have the problem that the number of customers in the filter section is small due to the need to downsize, and the filtration capacity is less than 1 minute. The problem was that it took a long time to complete and was extremely difficult to use.

Accordingly, Ganto Honda developed a water quality improvement device for drinking water a' which employs a bubble generating means that generates large bubbles and an ozone generating means. This drinking water quality improvement device was an extremely groundbreaking invention that decomposed chlorine and trihalomethane with air bubbles and prevented the growth of bacteria through the sterilizing power of ozone.

“Problem to be solved by the invention” However, the conventional drinking water quality improvement device described above
Although it was effective in decomposing M elements and I/rehalomethanes, increasing dissolved oxygen levels, and preventing the growth of bacteria, there was no function to adjust the temperature of drinking water, and the water after water quality improvement had to be transferred to another container. It was necessary to change the container and cool it in a refrigerator. This work was extremely old-fashioned and had the problem of being inefficient.

Particularly when making water for whisky, etc., there is a problem in that cold water cannot be prepared quickly.

Furthermore, when making infant formula, it is necessary to mix powdered milk by dissolving it in drinking water that is close to the infant's body temperature9.
However, there was a problem in that the water temperature during the midwinter period was relatively low, and drinking water with improved water quality had to be reheated. This work of heating drinking water is not only extremely tedious for the mother, but also distracts from the child's attention, which may lead to an accident.

"Means for Solving the Problems" The present invention was devised in view of the above problems, and includes a tank body for storing drinking water, and a system for releasing air bubbles into the drinking water stored in the tank body. a gas bubble generating means for supplying gas to the bubble generating means; a gas supply means for supplying gas to the bubble generating means; an ozone generating means for mixing ozone into the gas supplied by the gas supply means; It consists of a heat exchanger for cooling or heating the stored drinking water. The heat exchanger of the present invention may also include a joining member made by joining at least two different types of metal bodies, and a switch member for switching the direction of current flowing through the joining member9. , a tank body for storing drinking water, an inlet for filling the tank body with drinking water, an outlet for discharging the drinking water stored in the tank body, and a tank body for storing drinking water. a bubble generating means for releasing bubbles into drinking water; a gas supply means for sending gas to the bubble generating means; and ozone being mixed into the gas supplied by the gas supply means. ozone generating means, ozone absorbing means inserted between the tank body and the outlet port, and a heat exchanger for cooling or heating the drinking water stored in the tank body. , the heat exchanger is
A joining member made by joining at least two different types of metal bodies;
It is characterized by comprising a switch member for switching the direction of current flowing through the joining member. Further, the bubble generating means used in the present invention comprises a hollow member having a plurality of holes and connected to the gas supply means, and a net member covering at least the upper part of the hollow member. The member may be formed with a curvature and may also be provided with an opening. The bubble generating means used in the present invention includes a gas discharge section connected to the gas supply means, a first net member formed on at least the upper surface of the gas discharge section, and a first net member formed on the first net member. a second net member that covers at least the upper part;
This second net member may be formed with a curvature and may also be provided with an opening.

"Operation" In the present invention configured as described above, the tank body stores drinking water, the ozone generating means mixes ozone into the supplied gas,
The gas supply means can supply gas to the bubble generation means, and the bubble generation means can discharge ozone-laced bubbles to the drinking water.

A heat exchanger then cools or warms the drinking water within the tank.

The present invention also provides a method for filling a tank body with drinking water from an inlet,
The bubble generating means is capable of releasing ozone-containing bubbles into the drinking water, and the ozone absorbing means inserted between the outlet and the tank body prevents ozone from flowing out from the tank body. Furthermore, it is also possible to remove ozone from drinking water flowing out from the outlet. When a current is passed through the joint member of the heat exchanger, heat is generated or absorbed at the joint between the two metal bodies due to the Peltier effect. Further, by operating the switch member and switching the direction of the current flowing through the joint of the joint member, the generation and absorption of heat can be reversed, and cooling and heating of the drinking water in the tank body can be switched.

In the bubble generating means of the present invention, the gas supplied from the gas supply means is released in the form of bubbles from the hole bored in the hollow member or the first net member formed in the gas release part. . Among these bubbles, relatively large bubbles remain in the upper net member and continue to grow. When the buoyancy of the remaining air bubbles exceeds the water pressure in the openings formed in the net member, large air bubbles pass through the openings and are discharged upward.

"Embodiment" An embodiment of the present invention will be described based on the drawings. As shown in FIGS. , a bubble generating means 3, an air pump 4, an ozone generating means 5, an inlet 6, an outflow lower, an ozone absorbing means 8, a filter member, an air filter 10, and a heat exchanger 300. ing.

As shown in FIG. 1, the main body 1 of the water quality improvement device has a portable bot shape with a handle 11, but it can be formed into any shape. The tank body 2 is for storing tap water and the like, and can improve the quality of water that tends to be stored. The bubble generating means 3 bubbles the gas sent from the air pump 4 and releases the bubbles into the tap water in the tank.

Here, the bubble generating means 3 will be explained in detail based on FIG. It consists of a section 34 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 connecting portion 36 connected to the hollow cylindrical member 31 and the air pump 4 are connected with a suitable hose member, and the air pump 4 is connected to the air bubble generating means 3. The gas is then pumped. The gas that has entered the hollow cylindrical member 31 becomes bubbles and flows out from the plurality of holes 311, 311, . . . . The size of the bubbles is determined by surface tension, temperature, the shape of the hollow cylindrical member 31, etc. b' [Thus, the size of the hole and the size of the bubble are not necessarily equal. For example, the hole 311.31 of the hollow circular member 31! If the diameter of - is 2.5 m, the generated bubbles will be of various sizes from about 0.1 mm to 20 mm. These bubbles reach the net member 32 while decomposing or coming into contact with each other and growing synthetically. If the mesh of this copper member 32 is, for example, about 25 to 3.0 mm, fine air bubbles will pass through the mesh member 323 and float upward, but air bubbles that have grown larger than the mesh will
The bubbles stay in the bubbles 2 and rise up the curved surface while growing larger.9 At this time, the bubbles generate ultrasonic waves and decompose various compounds. Here, although the large air bubbles staying in the net member 32 have buoyancy, the openings 3 formed in the net member 32
4 (for example, diameter of about 20III111), the bubbles are pushed by the water pressure and cannot pass through the opening 34 and float in the -L direction. However, as the bubbles grow and their buoyancy increases and exceeds the water pressure applied to the openings 34, the large bubbles will
pass through and rise to the surface. At this time, the number of accumulated bubbles is too large to instantly pass through the opening 34, so
The bubbles are compressed. Immediately after the air bubbles pass through the net member 32, the air bubbles are expanded b5 until they are balanced with the water pressure.

Further, since the opening 34 has a diameter of about 20 nu*, large bubbles are instantaneously fragmented and then synthesized again after passing through the opening 34 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 bubbles pass through the opening 331 of the outer frame 33, the shape of the bubbles is adjusted and the protrusion force of the bubbles can be amplified.

Note that the bubble generating means 3 of this implementation side has a plurality of holes 311.
Hollow member 3I having 311... was adopted, but
As shown in FIG. 4, 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 may be a hollow member having an open top surface, and a gas discharge section 37 having a rectangular cross section may also be adopted. 9. The hole 311 of the hollow cylindrical member 31 of the bubble generating means 3 can generate bubbles.
It fulfills the same function as 311.... Since this first net member 38 does not require the formation of hole members, it has the effect of reducing manufacturing costs9.
Note that the other functions are the same as those of the embodiment using the hollow circular member 31, so a description thereof will be omitted.

The air pump 4 corresponds to a gas supply means and is for pumping gas to the bubble generation means 3.

This air pump 4 can be employed as an appropriate gas supply means such as a compressor. This air pump 4
Since the blowing pressure is required rather than the blowing air volume, a reciprocating pump is preferable to a rotary pump.

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

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 quartz ultraviolet lamp 52 is for generating ozone, and the air blown from the inlet 55 is mixed with ozone and sent out from the outlet 56. This is a low-pressure mercury discharge lamp that uses a transparent quartz tube, so that the short-wavelength ultraviolet rays (far ultraviolet rays) generated from the internal mercury vapor discharge are hardly absorbed by the outer tube and are all emitted to the outside. It is configured. 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 functions in the same way as a general fluorescent lamp, and not only starts the quartz ultraviolet lamp 52 but also stabilizes the discharge current Kf after starting. Note that the quartz ultraviolet lamp 52 can be driven using an inverter without using the glow lamp 54. The quartz ultraviolet lamp 52 does not generate nitrogen compounds, so it is extremely safe.

The inlet 6 is an opening through which tap water flows 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 inlet 6 and the tank body 2, and can remove deafness, foreign substances, etc. from the tap water. Although a normal filter is used as the filter member 9, a sterile filter can also be used in combination.

The outflow lower is for discharging the water after water quality improvement stored in the tank body 2. An ozone absorption means 8 is inserted between the outflow lower and the tank body 2. This ozone absorption means 8 is made of activated carbon, and absorbs ozone released from bubbles in the water, as well as ozone contained in the water flowing out from the outflow lower, and eliminates ozone-specific odor and dissolved ozone. can be absorbed. Moreover, the ozone absorption means 8 can prevent 'jtl bacteria etc. from entering from the outside. The air filter IO is inserted between the outside air and the air pump 4, and is configured to prevent dust and foreign matter from entering the air.

The main body 1 of the water quality improvement device of this embodiment can have a structure in which the tank chamber 2, the inlet 6, and the outflow lower are fixed in the main body, but they can also be structured so that they can be separated. In this case, the cut-off portion becomes lightweight, making it easier to transport when supplying and draining water.

Next, the heat exchanger 300 will be explained based on FIGS. 1 and 6. The heat exchanger 300 includes an electronic refrigeration element 310, a switch means 320, a power supply section 330, and a water side radiator 340.
and an external heat sink 350. Electronic refrigeration element 3
No. 10 generates or absorbs heat using the Peltier effect.

Here, the Peltier effect refers to the joining of two different metals,
When electricity is applied from one end to the other end, the metal side of one end becomes colder and the other end becomes hotter. Moreover, when the direction of the current is switched to the opposite direction, the metal at one end becomes hot and the temperature at the other end becomes cold. 4.Electronic refrigeration is a method of freezing that utilizes this principle. In this embodiment, as shown in FIG. 6, the electronic refrigeration element 310 includes a P-type semiconductor 311, an N-type semiconductor 312, a first metal temporary mold 1ji 313, and a second metal plate electrode 314.
314. In this embodiment, the two different metal bodies are a P-type conductor 311 and an N-type semiconductor 311.
12, however, the material for the pond is not limited to these materials, and other materials can be selected. When a current is passed through this electronic refrigeration element 3, heat is generated or absorbed at the junction due to the Peltier effect.9 This heat absorption result becomes Q=αT c I . Here, α is the sum of the thermoelectric powers of the two semiconductors. The electronic refrigeration element 310 is sandwiched between the water side 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 supply polarity is employed. Power supply section 330
is a normal DC power supply, and has a rectifier circuit, smoothing circuit, etc. installed inside.

In addition, in the heat exchanger 300 of this embodiment configured as above 9 in which it is possible to adopt a stabilized power source, when the switch means 320 is set to cooling down, the electronic refrigeration element 310 performs three heat absorption operations. Drinking water in the tank body 2 is cooled. That is, the electronic refrigeration element 310 can take heat from the water side radiator 340 and release this heat from the external radiator 350 to the atmosphere. Furthermore, since the bubble generating means 3 and the like operate in parallel, it is possible to lower the water temperature while improving the quality of drinking water. Therefore, when the quality of the drinking water in the tank body 2 is completely improved after a predetermined period of time has elapsed, the water temperature decreases to temperature a, providing easy-to-drink and delicious drinking water. When the means 320 is switched to the fan heating side, the current flowing through the electronic refrigeration element 310 is reversed, the electronic refrigeration element 310 performs a heating operation, and the tank body 2
The electronic refrigeration element 310 that heats the drinking water inside takes heat from the external radiator 350 and transfers this heat to the water-side radiator 340.
It is possible to heat the drinking water in the tank body 2 by releasing it from the tank body 2.

As in the cooling operation, since the drinking water is heated while improving the quality of the drinking water, after a predetermined period of time has elapsed, drinking water at an appropriate temperature and with improved quality can be obtained.

Note that the heat exchanger 300 of this embodiment does not raise the temperature enough to boil drinking water. However, warmed o
If i+ water is heated with an appropriate heating means, it can be brought to a boil in a short time, and the oxygen in the water will not be lost to the perilla leaves. Therefore, it is possible to provide hot water with excellent flavor, making it ideal for Japanese tea, black tea, and the like. Note that if the electronic refrigeration element 310 is appropriately selected, the
℃, it is possible to obtain drinking water at a temperature of about 60 to 70 ℃ when heated.

Further, the water quality improvement device main body 1 of this embodiment can be equipped with a control section consisting of a microcomputer or the like.

This control section includes a control means 100, a mode changeover switch 110, a light receiving element 120, a reset switch 130, a timer means 140, and a display 150. The mode changeover switch 110 is a switch for switching between normal mode and rapid mode, and when set to rapid mode, a completion sign can be output to display means 150 at the time when the sterilization effect is almost completed (for example, after one hour). . Furthermore, when switching to the normal mode, an end sign can be output at the time when the sterilization action is sufficiently completed (for example, after 4 hours). The timer means 140 sends a time-related control signal to the control means 100.

The water quality improvement device equipped with the control unit configured as described above is
When the tank body 2 is filled with tap water and attached to the water quality improvement device 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 the timer means 140 controls the ozone generation means 5 after 4 hours. When the signal is received, a termination 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 an end sign to the display means 50 after one hour. Note that the timer means 140 may be built into the control means 100, and further, the control means 100 may not control the drive means 200. In addition, tank body 2
When replenishing tap water with the water quality improvement device attached to the main body l of the water quality improvement device, it is preferable to press the reset switch 130. In this case, the count of the timer means 140 can be initialized to measure time. The times of the normal mode and the rapid mode can be set as appropriate depending on the volume of the tank body 2, etc.

Further, in the control unit of this embodiment, a light receiving element 120 is provided in the ozone generating chamber 51, which is equipped with a deterioration detection function of the quartz ultraviolet lamp 52, and receives the light beam of the quartz ultraviolet lamp 52. The output signal is sent to the control means 100. The control means 100 determines deterioration of the quartz ultraviolet lamp 52 from a decrease in the output signal of the light receiving element 120, and maintains a constant output signal.

If the value is below 1, a warning prompting the user to replace the quartz ultraviolet lamp 52 can be displayed on the display means 150.

In addition, a plurality of quartz ultraviolet lamps 52 are installed, and the control means 1
If 00 determines that the quartz ultraviolet lamp 52 in use has deteriorated, it may be configured to automatically switch to an unused quartz ultraviolet lamp 52.

It is also possible to connect the switch means 320 of the heat exchanger 300 to the control means 100. This switch hand 1
4320e, an electronic switching means consisting of a power transistor, etc., the electronic refrigeration element 310 is used as the control means 100.
This allows automatic switching between cooling and heating operations. 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 'a temperature.

In this embodiment configured as shown below, the air pump 4 generates ozone from the air filtered by the air filter.
Pressure feed to stage 5. Here, the ozone generated by the ozone generating means 5 is mixed and sent to the bubble generating means 3. Since the bubble generating means 3 generates bubbles of various sizes, it has the effect of being able to decompose various substances. When the large air bubbles pass through the openings 34 of the net member 32, they are compressed and the gas temperature increases. and opening 32
After passing through the gas, the bubble expands again and is rapidly cooled. However, since these bubbles are generated with a volume when the temperature rises, the volume decreases with subsequent cooling, and the surface tension increases. As a result, the bubbles appear to be hard, but when these bubbles are decomposed and synthesized, ultrasonic waves with more powerful energy than normal bubbles are generated. As a result, harmful substances such as chlorine and total trihalomethane can be rapidly decomposed.
It is a general term for trihalomethane, chloroform, promodichloromethane, dibromochloromethane, bromoform, etc. The bubbles can also dissolve a large amount of oxygen, and can increase the dissolved acid It in water. Dissolved acid @
Drinking water with increased M content has a sweeter taste and is easier to drink, making it ideal for diluting whiskey and other drinks.

Although it was possible to decompose chlorine 2 and carcinogens such as I-rehalomethane using the bubble generating means 3, there is a concern about the proliferation of bacteria since the sterilization effect of chlorine etc. is lost.
Since ozone is contained in the bubbles by the ozone generating means 5, the ozone has a sterilizing effect and is effective in preventing the propagation of germs. Furthermore, since ozone has a strong bleaching and oxidizing power, it can increase the rate of decomposition of chlorine, carcinogens, etc. Ozone itself is unstable, and as it changes into oxygen, it has the effect of increasing the amount of dissolved oxygen.

When testing this embodiment configured as described above, the eighth
As shown in the figure, residual chlorine decreases rapidly within one hour after the start of operation, and continues to decrease thereafter. Therefore, even in one-hour rapid mode, residual chlorine can be reduced by half or less9.
Similarly, as shown in FIG. 9, it is understood that the total trihalomethane value decreases by about half in one hour and continues to decrease thereafter.

In addition, the decomposition rate of chlorine, etc. can be increased by -L. Since the amount of dissolved oxygen in water can be increased by the bubble generating means and ozone, high quality water can be provided. Furthermore, since the heat exchanger cools or warms the drinking water in the tank body, there is an outstanding effect that the temperature of the drinking water can be maintained at an appropriate temperature while improving the quality of the drinking water.

Further, in the present invention, since an ozone absorbing means is inserted between the tank body and the outlet, ozone odor is not released to the outside and the ozone contained in the collected water is absorbed. It has the effect of being able to The bubble generating means of the present invention includes a hollow member having a plurality of holes and connected to 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 it is formed with an opening and an opening is provided,
Air bubbles f! on the curvature surface of the net member! : When the buoyant force of the bubbles exceeds the water pressure, the bubbles can be instantly floated up from the opening. Therefore, the bubbles are compressed when they pass through the opening, and can be expanded again after passing through the opening, which has the outstanding effect of generating high-energy bubbles 3 that have the ability to decompose substances such as @element. Since the bubble generating means generates large bubbles by synthetically growing small bubbles, a small gas supplying means is sufficient and energy saving can be achieved9. a first gas discharge part connected to the gas discharge part; and a first gas discharge part connected to the
In this case, there is no need to drill holes in the hollow member, so the cost is low.
This has the effect of making it possible to improve the
