Description

Description: TECHNICAL FIELD The present invention relates to water quality for decomposing harmful substances such as chlorine and trihalomethane contained in tap water and producing water sterilized by ozone. It relates to an improvement device.

"Prior art" As is well known, tap water is mixed with chlorine for sterilization. This chlorine sterilization has played a major role in preventing infectious diseases since the war. However, it has become clear that this chlorine chemically reacts with natural humic acid contained in the withdrawn raw water to produce carcinogens such as trihalomethane. In particular, the effect on infants is a serious problem, and water used for powdered milk and the like is instructed to be used after cooling boiled water.

Therefore, various water treatment devices such as water purifiers have been developed. General household water purifiers include a type that removes dust and germs by using a filter such as a micro filter, and a type that increases ions in water by using an ion exchanger. Most water filters were based on filters. In addition, there were two types of installation: a faucet direct connection type which is directly attached to a water tap, and an installation type which is installed in another place.

"Problems to be Solved by the Invention" However, the above-mentioned method of boiling tap water and using the cooled water takes time and labor to boil and cool.
Since the cooling water cannot be expected to have the sterilizing effect of chlorine, there is a problem that various bacteria grow. Therefore, the cooled water had to be used immediately, and handling was extremely troublesome.

And the water purifier of the above-mentioned filter system is rich in immediate effect,
Although it is effective in removing dust and foreign matter, it also removes chlorine for sterilization, so that there is a problem that germs grow in excess water and become extremely unsanitary. Furthermore, since the filter-type water purifier does not eliminate various bacteria and trihalomethane itself, but adsorbs them to the filter part, if the product is stopped for a long time and reused, serious germs that have propagated will flow out. There was a problem. In addition, the filter type water purifier needs to be replaced frequently because the filter portion is contaminated by use. However, in the water purifier, the filter portion occupies most of the cost of the water purifier, and there is a problem that the replacement cost is extremely high. The replacement time is generally left to the discretion of the user, and it has been difficult to determine the replacement time. In addition, the removal of organic compounds is effective immediately after installation, but there is a problem that the effect is lost even at about 10% of the rated flow rate.

And the faucet direct connection type water purifier has the problem that the capacity of the filter part is small and the overcapacity is not enough due to the need to reduce the size, and the stationary type has no overcapacity,
There is a problem that it takes a long time to take water because no water pressure is applied, and the usability is extremely poor.

In recent years, food poisoning and pathogenic Escherichia coli have been seriously damaged. , Was strongly desired.

"Means for Solving the Problems" The present invention has been devised in view of the above-mentioned problems, and has a tank body for storing water, an inflow port for filling the tank body with water, and the tank body. An outlet for discharging the water stored in the tank, a bubble generating means for discharging bubbles to the water stored in the tank body, and a gas for sending gas to the bubble generating means A supply unit, and an ozone generation unit for mixing ozone into the gas supplied by the gas supply unit, wherein the bubble generation unit is connected to the gas supply unit, and a gas for discharging the gas upward. A discharge member, a mesh member arranged to cover the upper part of the gas discharge portion, and for growing bubbles released from the gas discharge portion, and an outer frame member for accommodating the mesh member. , The mesh member is Along with being curved with an apex, near the apex, a growth bubble emitting portion for releasing a large grown bubble is formed,
The outer frame member is formed with a growth bubble discharge hole for discharging the growth bubbles discharged from the growth bubble discharge portion of the mesh member upward, and the ozone generating means includes a low-pressure mercury discharge lamp and a low-pressure mercury discharge lamp. And a driving means for driving the mercury discharge lamp.

Further, the ozone generating means of the present invention includes a light receiving element for receiving a light beam from the low-pressure mercury discharge lamp, a control means for detecting the deterioration of the low-pressure mercury electric lamp based on an output signal of the light-receiving element, and the control means. And a display unit that displays a warning on the display unit when the control unit detects the deterioration of the low-pressure mercury discharge lamp.

In the ozone generating means, the driving means drives the low-pressure mercury discharge lamp.

Further, the ozone generating means of the present invention is such that the control means detects deterioration of the low-pressure mercury discharge lamp based on an output signal of a light receiving element for receiving a light beam from the low-pressure mercury discharge lamp, and a display connected to the control means.

Embodiment An embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 2 and FIG. 2, reference numeral 1 denotes a main body of the water quality improvement device. The main body 1 of the water quality improvement device includes a tank 2, an air bubble generating means 3, an air pump 4, an ozone generating means 5, and an inflow port. 6, an outlet 7, an ozone absorbing means 8, a filter member 9, and an air filter 10.

As shown in FIG. 1, the water quality improvement device main body 1 has a portable pot shape provided with a handle 11, but can be formed in any shape. The tank body 2 stores tap water and the like, and can improve water quality while storing. The bubble generating means 3 is for forming bubbles in the gas sent from the air pump 4 and releasing 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 net member 32,
An outer frame 33 and a growth bubble emitting portion 34 formed on the mesh member 32
And a side wall member 35.

The hollow cylindrical member 31 has a plurality of holes 311, 311,.
A connecting portion 36 for connecting to the air pump 4 is provided continuously, and the connecting portion 36 protrudes from the side wall member 35.

The plurality of holes 311, 3 formed in the hollow cylindrical member 31
11 ... correspond to the gas release section.

Although the hollow cylindrical member 31 of the present embodiment is formed in a cylindrical shape, the hollow cylindrical member 31 is not limited to the cylindrical shape, but can be formed in any shape such as a rectangular parallelepiped.

The mesh member 32 covers at least the upper part of the hollow cylindrical member 31, and is formed to be curved with an apex upward.
A growth bubble emitting portion 34 is formed in the mesh member 31,
Large grown bubbles can be released into water.

The mesh member 32 may be made of any material, but it is desirable to use stainless steel.

The outer frame member 33 is for accommodating the mesh member 32, and the outer frame member 33 has a growth bubble discharge hole for discharging the growth bubble released from the growth bubble discharge portion 34 of the mesh member 32 upward.
331 are formed.

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

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 sent from the air pump 4 to the bubble generating means 3 under pressure. The gas that has entered the hollow cylindrical member 31 flows out of the plurality of holes 311 as air bubbles.

The size of this bubble depends on surface tension, temperature, hollow cylindrical member
It is determined by the shape and the like of 31. Therefore, the size of the hole and the size of the bubble are not always equal. For example,
If the diameter of the holes 311, 311... Of the hollow cylindrical member 31 is 2.5 mm, the generated bubbles will be various bubbles of about 0.1 mm to 20 mm. These bubbles reach the net member 32 while decomposing or growing in contact with each other. If the mesh of the mesh member 32 is, for example, about 2.5 to 3.0 mm,
Although the fine bubbles float upward through the mesh member 32, the bubbles that have grown larger than the mesh stay on the mesh member 32 and grow on the curved surface while growing further. At this time, the bubbles decompose various compounds while generating ultrasonic waves.

Here, the large bubbles staying in the mesh member 32 have buoyancy, but when the pressure is lower than the water pressure applied to the growth bubble emitting portion 34 (for example, about 20 mm in diameter) formed in the mesh member 32,
The bubbles cannot be lifted upward by passing through the growth bubble emitting portion 34 due to the water pressure. However, if you grow and increase the buoyancy to exceed the water pressure applied to the growth bubble emitting portion 34, the large grown bubble will float through the growth bubble emitting portion 34 of the net member 32.

At this time, since the volume of the staying bubbles is too large to pass through the growing bubble discharging portion 34 instantaneously, the bubbles are compressed. Immediately after the air bubbles pass through the mesh member 32, the air bubbles expand greatly until the water pressure and the balance are obtained. In addition, the growth bubble emission part
Since 34 has a diameter of about 20 mm, large bubbles are instantaneously fragmented and then recombined after passing through the growth bubble emitting portion 34 to become large bubbles. At this time, the water above the large bubbles is pushed up, so that a swirling flow is generated. The inside of the tank chamber 2 can be agitated by this swirling flow.

Then, when the bubbles pass through the growth bubble discharge holes 331 of the outer frame 33, the shapes of the bubbles are adjusted, and there is an effect that the protrusion output of the bubbles can be amplified.

Note that the gas releasing portion of the bubble generating means 3 of the present embodiment is constituted by the hollow member 31 having a plurality of holes 311, 311... Next, a modified example of the gas releasing portion will be described. I do.

As shown in FIG. 4, the gas discharging portion of the bubble generating means 3 of the present modification is constituted by a pipe member 37.
A bubble generating net member 38 is formed on the upper surface of 37.

The bubble generating means 3 of the present modification includes a pipe member 37 having a bubble generating net member 38 formed on the upper surface, a net member 32,
An outer frame 33 and a growth bubble emitting portion 34 formed on the mesh member 32
And a side wall member 35.

The pipe member 37 is connected to the air pump 4 and discharges gas into water. The pipe member 37 only needs to be a hollow member having an open upper surface, and a pipe member 37 having a rectangular cross section may be employed. The bubble generation mesh member 38 is attached to the opening on the upper surface of the pipe member 37, and can generate bubbles. .. Has the same function as the holes 311 of the hollow cylindrical member 31 of the bubble generating means 3.

Since the pipe member 37 in which the bubble generating net member 38 is formed on the upper surface does not need to form a hole member, there is an effect that the manufacturing cost can be reduced.

The other operation is the same as that of the embodiment using the hollow cylindrical member 31, and the description is omitted.

The air pump 4 corresponds to a gas supply unit, and pumps gas to the bubble generation unit 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 air volume, and a reciprocating pump is preferable to a rotary pump.

Next, the ozone generating means 5 will be described based on a fifth.
The ozone generating means 5 includes an ozone generating chamber 51, a quartz ultraviolet lamp 52, a stabilizer 53, and a glow lamp 54.

The ozone generation chamber 51 is a closed container, and a quartz ultraviolet lamp 52 is provided inside. In the ozone generation chamber 51, an inlet 55 and an outlet 56 are formed, and
The air blown from 55 is mixed with ozone 9 and sent out
It is sent from 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-wavelength ultraviolet light (far ultraviolet light) generated from discharge of mercury vapor inside. Are hardly absorbed by the outer tube and are radiated to the outside. In particular, the wavelength is 185n
The quartz ultraviolet lamp 52 of m can generate ultraviolet rays that generate ozone in air called ozone rays.

The ballast 53 and the glow lamp 54 correspond to the driving means 200 of the low-pressure mercury discharge lamp. The driving means 200 has a function similar to that of a general fluorescent lamp, and activates the quartz ultraviolet lamp 52 and stabilizes a discharge current after the activation. In addition, without using the glow lamp 54,
The quartz ultraviolet lamp 52 can be driven by using an inverter. The quartz ultraviolet lamp 52 has an effect of being extremely safe because it does not generate a nitrogen compound.

The inflow port 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 inflow port 6 and the tank body 2 to remove dust, foreign matter, and the like in tap water. A normal filter is used for the filter member, but a sterile filter may be used in combination. The outlet 7 discharges the water stored in the tank body 2 after the water quality has been improved. Outlet 7 and tank 2
The ozone absorbing means 8 is inserted between the two. The ozone absorbing means 8 is made of activated carbon, absorbs ozone released from bubbles in water, and has an outlet 7.
It absorbs ozone contained in the water flowing out of the tank and absorbs the odor peculiar to ozone and dissolved ozone.

Further, the ozone absorbing means 8 can prevent invasion of germs and the like from the outside. The air filter 10 is inserted between the outside air and the air pump 4 so as to prevent dust and foreign matter in the air from entering.

The main body 1 of the water quality improvement device of the present embodiment includes a tank chamber 2
The inflow port 6 and the outflow port 7 can be configured to be fixed in the main body, but they can also be configured to be separable. In this case, since the separated portion is measured, there is an effect that transportation at the time of water supply and drainage becomes easy.

Further, the water quality improvement device main body 1 of the present embodiment can be equipped with a control unit including a microcomputer or the like.

The 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 switching switch 110 is a switch for switching between the normal mode and the rapid mode. When the mode is set to the rapid mode, an end sign can be output to the display means 150 at a time when the sterilization operation is almost finished (for example, one hour later). . When the mode is switched to the normal mode, an end sign can be output at a time when the sufficient sterilization operation ends (for example, four hours later). The timer means 140 sends a control signal relating to time to the control means 100.

When the water quality improvement device provided with the control unit configured as described above is filled with tap water in the tank body 2 and attached to the water quality improvement device main body 1 and the mode switch 110 is set to the normal mode, the control means 100 When the ozone generator 5 is driven and a control signal four hours later is received from the timer 140, an end sign can be displayed on the display 150. Similarly, when the mode change switch 110 is set to the rapid mode, the control means 110 can output an end sign to the display means 150 after one hour.

Note that the timer means 140 may be built in the control means 100, and the control means 100 may not be configured to control the driving means 200. When tap water is replenished with the tank body 2 attached to the water quality improvement device 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 time counting can be performed.

In addition, the time in the normal mode and the time in the rapid mode can be appropriately set according to the volume of the tank body 2 and the like.

In the control unit of the present embodiment, a deterioration detecting function of the quartz ultraviolet lamp 52 is mounted, a light receiving element 120 is provided in the ozone generation chamber 51, and receives the light beam of the quartz ultraviolet lamp 52,
The output signal of the light receiving element 120 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 becomes equal to or less than a certain output signal, displays a warning prompting the replacement of the quartz ultraviolet lamp 52 on the display means 150. can do.

Also, a plurality of quartz ultraviolet lamps 52 are mounted,
When 0 determines that the quartz ultraviolet lamp 52 in use is deteriorated, the quartz ultraviolet lamp 52 may be automatically switched to an unused quartz ultraviolet lamp 52.

The present embodiment configured as described above has an air pump 4
Sends the air filtered by the air filter to the ozone generating means 5 under pressure. Here, the ozone generated by the ozone generator 5 is mixed and sent to the bubble generator 3. Since the bubble generating means 3 generates bubbles of various sizes, there is an effect that various substances can be decomposed.

Then, the large bubbles are compressed when passing through the growth bubble emitting portion 34 of the mesh member 32, and the gas temperature rises. Then, when passing through the growth bubble generating section 32, the bubbles expand again and are rapidly cooled. However, since these bubbles are generated by deposition when the temperature rises, the volume is reduced by the subsequent cooling, and the surface tension is increased. For this reason, at first glance, the air bubbles appear to be hard, but when the air bubbles are decomposed and synthesized, ultrasonic waves having energy stronger than that of ordinary air bubbles are generated. As a result, harmful substances such as chlorine and total trihalomethane can be rapidly decomposed. 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 amount of dissolved oxygen has a sweet taste and is easy to drink, and is most suitable for whiskey and the like.

In addition, although chlorine was decomposed by the bubble generation means 3 and carcinogens such as trihalomethane could be decomposed, the sterilization action of chlorine and the like was lost, and there was a concern about propagation of various bacteria.
Since ozone is contained in the air bubbles by the ozone generating means 5, the ozone has a sterilizing effect and has an effect that no germs are propagated. Further, ozone has a strong bleaching power and an oxidizing power, so that it can increase the decomposition rate of chlorine, carcinogens and the like. Ozone itself is unstable and has the effect of increasing the amount of dissolved oxygen because it changes to oxygen.

When the present embodiment having the above-described structure was tested, as shown in FIG. 7, the residual chlorine rapidly decreased one hour after the start of the operation, and continued to decrease thereafter. Therefore, even in the one-hour rapid mode, the residual chlorine can be reduced to half or less. Similarly, as shown in FIG.
It is understood that it is reduced by about half in time and continues to decrease thereafter.

[Effect] The present invention configured as described above has a tank body for storing water, an inflow port for filling the tank body with water, and an outlet for discharging the water stored in the tank body. Outlet, bubble generating means for discharging bubbles to the water stored in the tank body, gas supply means for delivering gas to the bubble generation means, and gas supply means. Ozone generation means for mixing ozone into the supplied gas, wherein the bubble generation means is connected to the gas supply means, and a gas discharge part for discharging gas upward, It is arranged so as to cover the upper part, and is composed of a net member for growing bubbles released from the gas discharge part, and an outer frame member for accommodating the net member. And it is curved In both cases, a growth bubble emitting portion for emitting a large grown bubble is formed in the vicinity of the vertex, and the outer frame member is for carrying out the growth bubble emitted from the growth bubble emitting portion of the mesh member upward. A growth bubble discharge hole is formed, and the ozone generation means is composed of a low-pressure mercury discharge lamp and a driving means for driving the low-pressure mercury discharge lamp. The carcinogen can be decomposed, ozone generated from the ozone generating means can prevent the growth of various bacteria, and can increase the decomposition rate of chlorine and the like.

Since the amount of dissolved oxygen in the water can be increased by the bubble generating means and the ozone, there is an effect that high quality water can be provided.

Further, according to the present invention, since the ozone absorbing means is inserted between the tank body and the outflow port, it does not emit gasified ozone odor to the outside and absorbs residual ozone contained in the extracted water. There is an effect that can be.

Further, the bubble generating means of the present invention employs a mesh member which is curved with an apex upward, and in the vicinity of the apex, a growth bubble releasing portion for releasing a large grown bubble is formed. Therefore, the bubbles can be retained on the curvature surface of the mesh member, and when the buoyancy of the bubbles exceeds the water pressure, the bubbles can instantaneously float from the opening. Therefore,
Since the bubbles are compressed when passing through the opening and can be expanded again after passing through the opening, there is an excellent effect that high-energy bubbles having a selected decomposition ability such as chlorine can be generated.

Since the bubble generating means grows large bubbles by synthesizing small bubbles, it is sufficient to use a small gas supply means, and there is an effect that energy can be saved.

The ozone generating means of the present invention includes a light receiving element for receiving a light beam from the low pressure mercury discharge lamp, a control means for detecting deterioration of the low pressure mercury discharge lamp by an output signal of the light receiving element, Since the control means detects deterioration of the low-pressure mercury discharge lamp, the control means can display a warning on the display means. The conversion of the mercury discharge lamp can be promoted.

Since the present invention as described above can provide drinking water in which carcinogens are decomposed, it has an outstanding effect that it can protect lives from infants, toddlers, and children who bear the next generation. In addition, since drinking water with a large amount of dissolved oxygen and increased sweetness can be obtained, it is most suitable for whiskey or the like. And if you wash your face with water with a large amount of dissolved oxygen, your skin will be activated and your face will be shiny and fresh, so it is ideal for women who are making great efforts in beauty.

Since ozone has an action of sterilizing pathogenic Escherichia coli and the like, it has an outstanding effect that it can be used for disinfecting dishes and the like with the generated ozone water and for washing gargle water and affected parts.
