Beverage Supply Apparatus Having Bubble Separation Means Next, a preferred example of an inline chlorine generation electrolysis apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto. Not something.

FIG. 1 or FIG. 3 is a side sectional view of an in-line chlorine generating electrolysis apparatus according to an embodiment of the present invention. Here, it is preferable that the structure of the electrode itself is as simple as possible. The cylindrical electrode 11 is composed of a cylinder of an electrode base material and an inner wall surface which is in contact with water to be treated and exerts an electrolytic action. Further, the concentric electrode 21 is composed of a rod-shaped or cylindrical electrode base material and an outer wall surface which contacts the water to be treated and exerts an electrolytic action, and may be simply referred to as the electrode 21 hereinafter.

A concentric electrode is disposed in a cylindrical electrode, connecting members 31 (31A to 31D) made of an insulating material are disposed on both ends thereof, and the concentric electrode is disposed and fixed substantially at the center of the cylindrical electrode.
The connection tool is polyethylene, polypropylene, ABS resin,
Resins such as polycarbonate, Teflon and polyacetal or insulating materials such as ceramic materials can be used. The connection tool has a through hole, and is fixed to a screw hole provided at the center of the concentric electrode 21 by a metal member (screw) 32 from the outside. Thereby, the cylindrical electrode 11 and the concentric electrode 21
Is only required to provide two screw holes in the concentric electrode 21,
High pressure resistance could be provided. Since the cylindrical electrode 11 and the concentric electrode 21 are made of titanium, the processing cost can be particularly reduced. The fixing screw is preferably made of titanium in consideration of strength and corrosion resistance. Further, a voltage for the concentric electrode can be supplied by using the fixing screw as a terminal. Further, in order to prevent water leakage from the gap between the fixing screw and the connector or the gap between the cylindrical electrode and the connector, it is desirable to provide an O-ring at this portion to further increase the pressure resistance.

A current collecting band 12 is fixed to the outer periphery of the cylindrical electrode 11, and an electrode terminal is provided on a part of the band.

The in-line chlorine generation electrolysis apparatus 10 of the present invention
Reference numeral 0 denotes an in-line chlorine generation electrolysis apparatus in which a concentric electrode 21 is disposed within the cylindrical electrode 11, a DC voltage is applied between the electrodes, and chlorine ions in the water to be treated passing therethrough are converted into residual chlorine. With such a configuration,
It can be installed so that it can be inserted halfway through the water pipe, making it easy to add it to existing equipment.

In order to optimize the chlorine generation efficiency, the inner wall surface of the cylindrical electrode 11 having the area A is used as an anode surface, and the outer wall surface of the cylindrical or rod-shaped concentric electrode 21 having the area B is arranged concentrically at substantially the center of the cylinder. Is used as a cathode surface, and the ratio of the area of both electrodes is 1.1 ≦ A / B ≦ 2.0, preferably 1.2 ≦ A
By setting /B≦1.6, it is possible to provide an in-line chlorine generation electrolytic device having high chlorine generation efficiency. The chlorine generation efficiency is higher as the area of the anode surface is larger than the cathode surface, but when the A / B ratio of both electrodes exceeds 2.0, the difference in current density between the anode surface and the cathode surface becomes too large. It is not preferable because the durability of the electrode itself is reduced. Further, the electrode area here means the area of a part which is actually in contact with the water to be treated and is involved in electrolysis, and includes a part which is covered with an insulating member for holding the electrode and the like. Not. For example,
Due to the assemblability of the in-line chlorine generating electrolysis apparatus 100, there is a case where the concentric electrode 21 formed of a rod or a tube is longer than the cylindrical electrode 11 formed of a cylinder. Concentric electrode 21

mm or less, preferably 20 mm or less.

The material of the electrode used in the in-line chlorine generating electrolysis apparatus of the present invention is not particularly limited as long as it is an electrode that can be used for electrolysis of water. An anode surface or a cathode surface coated with a white metal-based metal or the like by plating or firing is preferably used. In particular, as the anode surface material on the chlorine generation side, a high chlorine generation electrode whose electrode surface is made of platinum and iridium is preferable in terms of chlorine generation efficiency and durability. Alternatively, the efficiency of chlorine generation can be significantly increased by using an electrode having a platinum surface black or a crystal structure similar to platinum black on the surface of the electrode used for the cylindrical electrode and using a substantially larger surface area. Such a platinum coating may be prepared by plating, but may also be prepared by applying a platinum compound to the electrode surface and then firing.

FIG. 3 is a side sectional view of an in-line chlorine generating electrolysis apparatus using a connector according to another embodiment of the present invention.
Two pairs of electrodes are connected by four connectors to form an electrolytic cell. Although not shown in the drawing, an O-ring is used at the screw portion or the contact portion between the cylindrical electrode and the connector to prevent water leakage.

The applied voltage is preferably 5 to 25 VDC. In addition, in order to remove the scale composed of calcium, magnesium, and the like on the cathode surface, it is desired to invert the polarity of the electrode every certain energizing time or every number of energizations. Usually, 1-2 every 5-15 minutes
Reverse power for a minute. Alternatively, it is also possible to perform control such that backwashing is performed when the amount of electricity has reached a certain level. However, the original chlorine generation efficiency is 1 during reverse power.
However, there is a problem in that the water drops to ２〜 to １ ／, and it is necessary to drain the water during that time. In order to solve this, as shown in FIG. 1 or FIG. 3, an in-line chlorine generating electrolyzer is connected so that the voltage is applied to the two electrode pairs in reverse polarity, and then the connection circuit is connected. Positive electricity and reverse electricity are switched at a constant conduction time or the number of times of conduction, so that the electrolysis for generating chlorine and the electrolysis for removing scale always work alternately in each electrode pair. This enables continuous treatment at a constant efficiency at all times.Electrolysis treatment can be performed without stopping water flow or changing the flow path for drainage. Can be For example, if the polarity is inverted each time the energization is completed, the control unit does not need a counter, which can further simplify the operation. It is preferable to reverse the polarity every time or every 1 to 15 minutes of the cumulative energization time.

In the in-line chlorine generation electrolysis apparatus of the present invention, an electrolysis voltage is applied while water is flowing. For example, it is preferable to supply electric power or an electric signal to the in-line chlorine generation electrolytic device at the same time as supplying electric power to a pump or an electromagnetic valve for passing water through the in-line chlorine generation electrolytic device, and control application or stop of voltage.
That is, there is a water supply pump inside the beverage maker or in the attached carbonator unit. For example, in the case of producing carbonated beverages, water is supplied to the carbonator every one to several cups according to the capacity of the carbonator. That is, when the amount of water in the carbonator decreases, it is detected that the weight has become lighter, and water is automatically supplied. The pressurized carbon dioxide in the carbonator dissolves in the supplied water to become carbonated water. The in-line chlorine generation electrolysis of the present invention is performed when the drive voltage of the water supply pump (usually AC 100 V) is detected and used as a signal when the water is supplied, that is, when the water is supplied. A method of applying a DC voltage to the electrode portion of the device can be used. In this case, it is preferable to keep the DC power supply ON at all times and supply the power to the electrode unit only when the driving voltage is supplied, since the time lag of the voltage application is small.

It is preferable to control the residual chlorine concentration while the flow rate is substantially constant. However, by detecting the flow rate and adjusting the electrolysis voltage according to the flow rate, the residual chlorine concentration generated is controlled. Can also be controlled. Alternatively, the chlorine concentration can be controlled by adjusting the electrolytic voltage according to the quality of the water to be treated (electric conductivity, chloride ion concentration, water temperature pH, etc.).

The DC power supply may be a constant-voltage power supply or a constant-current power supply, but a constant-current power supply in which the amount of chlorine produced hardly changes due to fluctuations in water quality is preferable. Even in such a case, it is desirable that the configuration be such that the actual amount of chlorine generation can be confirmed by the DPD method or the like, and the current value can be manually changed according to the region and season. The current value is set depending on the electrode to be used. However, a current density of 0.5 to 5 A / dm2 is preferably used, and a necessary chlorine amount can be obtained. It is also preferable from the viewpoint.

In the in-line chlorine generating electrolysis apparatus of the present invention, the linear velocity of the water to be treated in the electrolytic cell is 10 to 10%.
It was confirmed that chlorine can be efficiently generated at 0 cm / sec, preferably 20 to 70 cm / sec. When the linear velocity is 10 cm / sec or less, electrolysis is hindered by the influence of the generated gas. Conversely, if the linear velocity is too high, a sufficient residual chlorine concentration cannot be obtained.

The concentration of residual chlorine which can be generated by the in-line chlorine generating electrolysis apparatus of the present invention is usually 0.1 to 2 p.
pm, preferably 0.3 to 1.5 ppm.

The in-line chlorine generating electrolyzer according to the present invention can be used as a single electrolyzer, but a plurality of electrolyzers can be arranged in series to increase the residual chlorine concentration or to use a plurality of electrolyzers (not shown). Are installed in parallel to increase the amount of water flow.

Further, as shown in the schematic configuration diagram of FIG. 4, for example, in the case of a post-mix cup-type beverage manufacturing apparatus 60, a cartridge filter 62, an activated carbon treatment, etc. The water that has passed through the tank 63 is supplied to the ice maker 67 or the carbonator 66 in the post-mix cup-type beverage manufacturing device 60 through the in-line chlorine generating electrolytic device 100 and the electrolytic gas removing device 40. The in-line chlorine generating electrolysis apparatus 100 can compensate for residual chlorine that has been reduced by natural disappearance or activated carbon treatment, and can maintain the inside of the piping of the post-mix cup-type beverage manufacturing apparatus 60 in a sanitary manner.

In the pre-treatment of water used in this post-mix cup-type beverage manufacturing apparatus, when an in-line chlorine generating electrolyzer for converting chlorine ions in the water to be treated into residual chlorine is provided downstream of the activated carbon treatment, It is desirable to provide an electrolytic gas release device for removing the electrolytic gas generated in the in-line chlorine generating electrolyzer downstream of the in-line chlorine generating electrolyzer. Electrolysis produces fine bubbles of oxygen and hydrogen, which accumulate in the carbonator, which produces carbonated water, which lowers the partial pressure of carbon dioxide in the carbonator and reduces the efficiency of carbon dioxide dissolution. is there.

In order to solve this problem, a water reservoir open to the atmosphere may be provided downstream of the electrolytic cell, but in that case, a large space is required. For this reason, it is desirable to provide an electrolytic gas venting device 40 for gas-liquid separation as shown in FIG. 5 as an electrolytic gas venting device. A passage for the bubble-containing water 44 is provided at the center, where the bubbles rise to the top and accumulate in the upper space of the electrolytic gas venting device 40. The accumulated gas is discharged outside from the gas discharge port 45 by operating the gas release valve 47. The water 46 from which air bubbles have been substantially removed is introduced into the post-mix cup-type beverage manufacturing apparatus 60.

The sum of the volume of the piping between the in-line chlorine generating electrolytic device and the electrolytic gas venting device and the volume of the electrolytic gas venting device capable of holding water is determined by the post-mix cup type beverage producing device. In order to maintain sufficient gas-liquid separation efficiency, it is particularly desirable that the gas-liquid separation device be arranged so as to have a capacity of one or more water consumptions required for the production of water. This is because the electrolytic gas is in a very fine bubble state immediately after generation, and is easily swept away by a gas-liquid separator with a simple structure, but becomes relatively large bubbles if left for a certain period of time, which facilitates separation. . Especially when producing non-carbonated beverages (e.g. tea, orange juice, etc.) with a post-mix cup-type beverage production device, the water flow is intermittent and will be produced one cup at a time, so at that time Gas-liquid separation is performed. Usually, the water used to make one cup of beverage is 200-
Since the volume is about several hundred ml, the sum of the volume of the downstream piping portion of the in-line chlorine generating electrolyzer and the volume of the electrolytic gas venting device that can hold water may be about 200 to several hundred ml or more.

In another embodiment of the present invention, the electrolytic gas can be more efficiently removed. That is, as shown in FIG. 2, in the pretreatment of the raw water used in the post-mix cup-type beverage manufacturing apparatus, the chlorine ions in the water to be treated are converted into residual chlorine downstream of the activated carbon treatment of the raw water. In the method of providing an in-line chlorine generating electrolyzer 100 for removing electrolytic gas on the downstream side of the in-line chlorine generating electrolyzer, the electrolytic gas venting device 40 includes a cylindrical cartridge filter 4 having an average pore diameter of 0.1 to 100 μm.
3 is a filter housing with built-in 3 and sends bubble-containing water 44 from the lower portion to the inside of the cartridge filter,
By passing the cartridge filter from the inside to the outside, the fine bubbles grow into larger bubbles, the grown bubbles accumulate in the upper space of the filter housing, and the water 46 from which the bubbles have been removed is discharged to the lower outlet. The gas discharged and accumulated is released from the gas discharge port 45 by operating the valve 42 provided at the upper part of the filter housing. This makes it possible to remove the electrolytic gas. In the gas-liquid separation using this method, the same effect can be obtained even if the liquid is sent from the outside to the inside of the cartridge filter.

As a result of intensive studies to improve the efficiency of removing fine electrolytic gas, bubbles can be more efficiently separated by setting the inlet of the electrolytic gas venting device to 3.5 kgf / cm 2 or less when passing water. Was confirmed.
This is presumed to be because the bubbles are compressed and difficult to separate under pressure. It is preferable to use a filter medium having a pressure loss of about 0.1 to 2 kgf / cm2. The selection may be made in anticipation of an increase in pressure loss due to clogging of foreign substances during use. The higher the pressure loss, the higher the gas-liquid separation efficiency tends to be.

When the inlet of the electrolytic gas venting device is passing water, 3.
In order to control the pressure to 5 kgf / cm 2 or less, it is preferable that the pressure reducing valve is disposed upstream of the electrolytic gas release device.

As the filter housing and the cartridge filter, commercially available ones can be used. However, it is preferable that water is supplied from the inside to the outside of the cartridge filter in a direction opposite to the normal direction. In that case, the cartridge filter may be pushed out from the inside to the outside by the water flow at the time of passing water, and may be detached. Therefore, FIG.
It is preferable to provide a fixture 68 for preventing the cartridge filter from deviating and / or to provide a screw groove in the cartridge filter itself and fix it by screwing it into the filter housing.

Further, the degassing device of the present invention is arranged as shown in FIG. 2 or FIG. 6, and a degassing valve is provided on the upper part. The vent valve may be of a manual cock type, but an air vent valve having a structure that opens by buoyancy when a certain amount of gas accumulates is used. Preferably, a solenoid valve 48 is used.

It is desired that the gas separated in the electrolytic degassing device is released to the outside at regular intervals. This is achieved by opening a degassing valve (solenoid valve) by a timer at regular intervals of electrolytic time. It is desired. It is particularly desirable that this timer device is shared with a timer device used for inverting the polarity of electrolysis every fixed water passage time of the in-line chlorine generation electrolytic device.

On the other hand, a certain time (0.5
〜5 seconds) It is also possible to design to open the vent valve, in which case the timer device is not particularly required. In addition,
It is preferable that the opening time of the degassing valve can be adjusted as required by a volume switch or the like comprising a variable resistor in the control device. Since the chlorine-containing water is discharged through the solenoid valve every time, the inside of the exhaust / drain tube connected to the solenoid valve can be maintained in a sanitary manner, which is particularly preferable in an installation place where the number of beverage production is small. exhaust·
Since oxygen and hydrogen generated by the electrolysis are discharged from the drain tube, it is preferable from the viewpoint of safety to discharge a small amount at a time rather than discharging a large amount at a time. The discharge amount per discharge is about 1 to several tens of ml including gas and water, though it depends on the water pressure.
Further, particularly when the tube has not been used for a long period of time, a larger amount can be flowed for cleaning the inside of the tube.
The exhaust / drain tube may be provided with a check valve if necessary.

Another object of the present invention is to provide a method for controlling an electrolytic gas release device. That is, in the pretreatment of water used in the post-mix cup-type beverage manufacturing apparatus, an in-line chlorine generating electrolyzer for converting chlorine ions in the water to be treated into residual chlorine is provided, and electrolysis is performed downstream of the in-line chlorine generating electrolyzer. In a water treatment device provided with a degassing device, the voltage applied to the electrode of the in-line chlorine generation electrolysis device has a function of inverting the polarity of electrolysis every fixed energizing time by a timer device, and further by the same or another timer device. Controlling the opening and closing of a gas vent valve for releasing gas accumulated in the electrolytic gas venting device at regular time intervals, and when opening the gas venting valve at regular time intervals or at designated time intervals, the timer device vents gas. Even when the valve is opened, it waits without opening the degassing valve during water supply for beverage production, and waits for the beverage production. After the water has been completed, a control method of the electrolytic degassing device and controls to open the specified time vent valve. When the timing of opening the vent valve of the electrolytic gas venting device is controlled by a timer that counts the electrolysis time, the timing of opening the vent valve during beverage production comes. However, since the gas vent valve is opened during the production of the beverage and the gas is pushed out of the electrolytic gas venting device by the pressure of the water (tap pressure, etc.), where the water pressure is 3 kgf / cm2 or more,
Opening the degassing valve when passing water has little effect that drinking water is less likely to be sent to the downstream side.However, when the tap water pressure is low or the activated carbon filter installed upstream of the in-line chlorine generation electrolytic device When clogging was clogged, there was a problem that it became difficult to supply drinking water to the downstream side of the degassing device. In this case, the amount of water supplied from the in-line chlorine generation electrolytic device to the degassing device may be lower than the amount of water supplied by the water supply pump incorporated in the beverage production device, and the pressure in the degassing device may be temporarily reduced. Was. Therefore, this problem could be solved by opening the degassing valve after the production of the beverage without opening the degassing valve of the electrolytic degassing device during the water flow.

The present invention also provides a method for controlling another electrolytic gas venting device. That is, in the pretreatment of the water used in the post-mix cup-type beverage manufacturing device, an in-line chlorine generating electrolytic device for converting chlorine ions in the water to be treated into residual chlorine is provided, and further, a downstream side of the in-line chlorine generating electrolytic device. A gas venting device is installed in the system, and chlorine is generated by the chlorine generating electrolyzer when passing water, and gas is temporarily stored in the electrolytic gas venting device. A method of controlling an electrolytic gas venting device that opens a gas venting valve for a specified time. In particular, by opening the degassing valve for a specified time each time water flow ends,
There is no need to provide a counter or the like. Then, it is important to open the degassing valve for a specified time after waiting for a certain time after passing the water. Depending on the installation location of the beverage production machine, or when the activated carbon filter installed upstream is clogged, the amount of tap water supplied is insufficient,
In some cases, the suction capacity of a water pump built in a beverage maker is higher. In this case, the inside of the electrolytic degassing device may be in a decompressed state, and when the degassing valve is opened immediately after the end of water supply for beverage production, air or water may be sucked from the degassing valve. Therefore, by controlling the electrolytic degassing device to open the degassing valve for a specified period of time after waiting for a certain time after passing water, the degassing valve is opened after the inside of the degassing device is restored to the water pressure. Could solve this problem. After completion of the water flow, the waiting time before opening the degassing valve is preferably 0.2 to 5 seconds.

Another object of the present invention is to provide another control method for an in-line chlorine generating electrolytic apparatus for a post-mix cup-type beverage production apparatus. That is, in the pretreatment of the water used in the post-mix cup-type beverage manufacturing apparatus, an in-line chlorine generation electrolysis apparatus for converting chlorine ions in the water to be treated into residual chlorine is provided downstream of the activated carbon treatment, and the in-line chlorine generation is performed. In a water treatment system that has an electrolytic gas venting device downstream of the electrolytic device, a post-mix cup-type beverage that generates electricity by supplying electricity to the in-line chlorine generating electrolytic device even when the vent valve is opened from the electrolytic gas venting device. This is a method for controlling an in-line chlorine generation electrolysis apparatus for a manufacturing apparatus. The gas venting valve is opened when a certain amount or amount of the electrolytic gas accumulates in the electrolytic gas venting device, and the gas is pushed out using water pressure such as tap water pressure. At this time, water for pushing out the gas flows in from the upstream side, which is used for beverage production, which is not hygienic. Therefore, even when the degassing valve was open, chlorine could be generated by supplying a DC voltage to the in-line chlorine generation electrolysis apparatus to solve this problem.

By the way, by using the degassing device of the present invention, accumulation of the electrolytic gas in the carbonator can be significantly reduced. However, it is difficult to make it completely zero, and some accumulation is inevitable.
Therefore, the present invention also provides a method for discharging the electrolytic gas accumulated in the carbonator to the outside of the carbonator. That is, on the downstream side of the activated carbon treatment of the raw water used in the post-mix type cup-type beverage production device, an in-line chlorine generation electrolytic device for converting chlorine ions in the water to be treated into residual chlorine is provided, In the method of removing the electrolytic gas on the downstream side, an electromagnetic valve was arranged above the carbonator to which the water treated by the in-line chlorine generating electrolytic device was supplied, and the electromagnetic valve was periodically opened to accumulate in the carbonator. This is a method of discharging the electrolytic gas outside the carbonator, which comprises discharging the air or the electrolytic gas. The interval at which the solenoid valve is opened can be determined by counting the number of beverage productions (or time) and opening the solenoid valve at regular intervals. At this time, carbon dioxide in the carbonator is also discharged. After careful examination of the discharge timing, the water in the carbonator was half of when it was full.
At the above time, it was confirmed that when the opening timing was set so that the electromagnetic valve was opened and the air or the electrolytic gas accumulated in the carbonator was discharged, the discharge amount of carbon dioxide gas could be suppressed accordingly. That is, for example, between opening the solenoid valve immediately after water is supplied to the carbonator and before the production of the first carbonated beverage is performed, and opening the solenoid valve when the water of the carbonator is at the state of the lower limit. The latter is uneconomical due to the large amount of wasteful carbon dioxide exhaust. Therefore, when the water in the carbonator is half or more of when the water is full, preferably, the solenoid valve is set to be opened immediately after the water is supplied to the carbonator until the first carbonated beverage is produced. Is preferred.
By doing so, it was confirmed that carbon dioxide wastefully exhausted for degassing can be reduced by about half.

If a metal member is used in the vicinity of the electrolytic cell of the in-line chlorine generator of the present invention, it may be corroded by electrolysis. Therefore, it can be prevented by not using a metal member in the vicinity of the electrolytic cell or by properly grounding.

The in-line chlorine generating electrolyzer of the present invention may be placed on a table or fixed to a wall. However, it is necessary to arrange the gas venting device so that the gas exhaust valve is located at the top. Therefore, by connecting the degassing device to the in-line chlorine generation electrolysis device with a rotatable structure (part A in FIG. 8) so that the mounting angle thereof can be changed,
As shown in FIG. 8 and FIG. 9, it is installed on a table (FIG. 9)
It can also be fixed to the wall with bolts or the like (FIG. 8). It is preferable that the rotating part can freely rotate 360 degrees, but it is sufficient if the rotating part can rotate only 90 degrees. Further, it is not always necessary to be able to rotate at all times, and if it can be rotated only during installation, it may be fixed after installation.

The in-line chlorine generation electrolysis apparatus of the present invention is intended for water to be treated containing chlorine ions.
In particular, fresh water having an electric conductivity of 500 μS / cm or less can be preferably treated. Furthermore, it is particularly preferably used for drinking water such as well water, city water, water supply, and the like, as a beverage manufacturing machine using such water or as ancillary equipment, or in a piping route of a building or an apartment, near a household water tap. (Under the sink) or the like. In particular, residual chlorine may be decomposed in a water storage tank such as a rooftop of a building, and installing it in the water storage tank or on the downstream side can maintain the sanitary condition of the piping to the use point.

In the in-line chlorine generating electrolyzer of the present invention, it is preferable to supply electricity when water is passed through the in-line chlorine generating electrolyzer. It is desirable to control the application and stop of the electrolysis voltage by using the signal of the above or the supplied power or the signal from the flow detecting means such as a flow switch as a control signal for electrolysis.
The water flow control valve for controlling water flow is preferably located downstream of the electrolytic gas release device, but is further provided upstream of the in-line chlorine generation electrolysis device so that abnormally high pressure caused by water hammer etc. It is also possible to prevent the device and the electrolytic degassing device from being applied. In this case, it is preferable to open the water passage valve on the upstream side when degassing.

Another embodiment of the in-line chlorine generation electrolysis apparatus of the present invention is shown in FIGS. FIG. 10 is an external view of the in-line chlorine generation electrolysis apparatus of the present invention. As an installation example, a tap water pipe is connected to a treated water inlet 117 through an activated carbon treatment tank 63 and a pressure reducing valve 119, and an electrolytic cell and a gas vent are internally provided. After passing through the apparatus, treated water comes out of the treated water outlet 118. This tip can be installed in a post-mix cup-type beverage production device, or can be connected to a faucet and used.

FIG. 11 is a perspective view showing the internal structure of the in-line chlorine generation electrolysis apparatus of the present invention shown in FIG. FIG. 12 is a cross-sectional view showing the electrolytic cell section and the gas vent section, and FIG. 13 is a perspective view showing the electrolytic cell section and the gas vent section. FIG. 14 shows a cross-sectional view of the electrolytic cell.

FIG. 14 shows that a concentric electrode is held by a connecting tool so as to be disposed substantially at the center of the cylindrical electrode, and that the connecting tool has an inlet or outlet for the liquid to be treated as required. A part of the concentric electrode provided with a thread penetrates the connection tool and is exposed to the outside, and this part is used as an electrode terminal for applying a voltage from the outside to the concentric electrode, and a nut is used. An in-line chlorine generating electrolytic device is shown, wherein a part of the threaded electrode is fixed to a connector. That is, as shown in FIG. 14, the electrolytic cell portion has a cylindrical electrode 11 and the concentric electrode 21 has a connector 31E and an electrolytic cell / gas release housing 12 as well.
3, a concentric electrode 21 is arranged at substantially the center of the cylindrical electrode 11. Usually, the distance between the poles is
1-2 mm is used. A part of the concentric electrode 21 is
It is exposed to the outside through E, and this portion is provided with a thread, and is fixed to the connector 31E by a nut. A rubber packing 122 is disposed between the concentric electrode 21 and the connection tool 31E to prevent water leakage. The exposed portion outside the concentric electrode 21 can be used as an electrode terminal 115 for applying a voltage from the outside to the concentric electrode. By exposing a part of the concentric electrode 21 to the outside, the assembly was extremely easy. In order to prevent the concentric electrode 21 from rotating during tightening when fixed with a nut, it is preferable to provide a through hole near the opposite end and insert a metal rod or the like into the through hole to tighten the nut. This through hole can also be used as a water passage hole at the end of the electrode.

FIG. 13 shows that at least one of the connectors made of an electrically insulating material for holding the electrodes of the present invention is formed integrally with the electrolytic gas venting device, and the water to be treated that has passed through the gap between the two electrodes. An example of an in-line chlorine generating electrolysis apparatus is shown, which has a water passage for feeding a liquid to an electrolytic gas venting apparatus and a housing containing a filter medium. That is, as shown in FIG. 13, one of the connectors is integrated with the gas vent portion to form the electrolytic cell / gas vent housing 123, so that not only can the cost be significantly reduced, but also water leakage can be prevented. We were able to reduce the number of connections that were concerned. The electrolytic tank / gas release housing 123 has a housing having a water passage through which the water to be treated is sent to the electrolytic gas release device and a filter medium. These can be made of a resin such as polyethylene, polypropylene, ABS resin, polycarbonate, Teflon, and polyacetal by molding or cutting. Alternatively, an insulating material such as a ceramic material can be used.

The solenoid valve for venting to be attached to the electrolytic gas venting device is provided at the upper part of the electrolytic gas venting device. However, if it is provided at the side of the upper part of the electrolytic gas venting device, it will be an obstacle for maintenance such as filter replacement. Not preferred. Further, it is more preferable that the filter housing has a cylindrical container for holding the filter and a structure having a lid at the top, because the water accumulated inside can be opened without completely removing the filter when the filter is replaced. As the filter to be used, a cylindrical filter is preferably used, and short-circuiting of bubbles may be prevented by rubber packings 110 above and below the filter as shown in FIG.

Further, in FIGS. 13 and 14, connecting members made of an electrically insulating material are provided at both ends of a cylindrical electrode whose inside also serves as a water passage, and both connecting members are connected via a support. An in-line chlorine generating electrolysis apparatus characterized by this is shown. That is, the connecting tools 31E and 123 made of an electrically insulating material are provided at both ends of the cylindrical electrode 11 and the concentric electrode 21, and the connecting tools are connected to each other via the support plate 120 as a support. is there. Thereby, the connection tool 31
The through hole in E becomes unnecessary on the 123 side, and the portion where water leakage is more likely to occur can be reduced. Further, instead of the support plate 120, the side surface or the bottom surface of the main body case containing these can be substituted, and only one of the processing on the concentric electrode side is required, which can greatly contribute to cost reduction. .

In FIGS. 11 to 13, an electrolytic gas venting device is provided downstream of the in-line chlorine generating electrolysis device, and a flow switch for detecting water flow is provided downstream of the device. There is shown an in-line chlorine generation electrolysis apparatus characterized in that a DC voltage is applied between the two electrodes when detected. That is, after the electrolyzed water to be processed passes through the filter 111 disposed in the degassing device, the flow switch 112 is disposed downstream of the degassing device. By using a flow switch, not only can it be freely installed in any part of the water supply pipe, but also by installing it downstream of the degassing device,
It is possible to prevent malfunction due to the flow of water when the gas discharge valve in the gas venting device is opened.

As a result of intensive studies to improve the gas separation efficiency of the electrolytic gas venting device of the present invention, the electrolytic gas venting device has a filter housing with a built-in filter, and the water to be treated containing air bubbles is passed through the filter. Gas-liquid separation is performed by passing the gas through, gas bubbles are accumulated in an upper space in the filter housing, water to be treated is discharged from a lower discharge port, and the accumulated gas is appropriately discharged from a valve provided in an upper portion of the filter housing, and It has been clarified that the gas separation efficiency of the electrolytic degassing device can be improved by controlling the pressure of the water to be treated after passing through the filter to be equal to or less than 1 kgf / cm2 in terms of the gage pressure during the passage of water. Especially the water pressure
Even when it exceeds 4 kgf / cm2, gas separation became possible efficiently. When the tap water pressure is 4 kgf / cm2, the bubbles of the electrolytic gas generated by the electrolysis are extremely fine, and there are many portions that pass without being trapped by the filter. 1kg by gage pressure when passing water
It has been confirmed that gas separation can be efficiently performed by setting the f / cm 2 or less. More preferably, when the pressure of the water to be treated after passing through the filter is in a reduced pressure state below the atmospheric pressure, a higher gas separation ability can be provided. If the pressure of the water to be treated after passing through the filter can be reduced to 1 kgf / cm2 or less by gage pressure at the time of passing water, water is passed from the outside to the inside of the filter disposed inside the housing of the degassing device, and An electrolytic gas venting device may be provided in which an air bubble discharge port is provided in the upper part and a treated water outlet after gas separation is provided in the lower part. In order to reduce the pressure of the water to be treated to 1 kgf / cm 2 or less at the time of passing the water, a pressure reducing valve is installed on the upstream side of the in-line chlorine generating electrolyzer as shown in FIG. It is desirable to reduce the water pressure on the inlet side of the generating electrolyzer to about 1-2 kgf / cm2.

Alternatively, if the outlet of the treated water from the degassing device can be opened to the atmosphere depending on the installation conditions, the pressure of the water to be treated after passing through the filter can be increased to 1 kgf / g at the time of passage of the filter. cm2 or less, and the pressure of the water to be treated after passing through the filter can be reduced to 1 kgf / gage at the time of passing water without installing a pressure reducing valve.
cm2 or less. Preferably, it is desirable to provide a flow rate restricting means upstream of the degassing device. When the in-line chlorine generator of the present invention is installed just before the faucet of the sink, it is possible to install it in this way.

Further, when the in-line chlorine generator of the present invention is used by connecting it to a cup-type beverage production machine or the like, the pressure of the water to be treated after passing through a filter built in the degassing device is increased when the water is passed. A flow restricting means is provided on the upstream side of the electrolytic gas venting device so that the pressure becomes 1 kgf / cm2 or less or the atmospheric pressure or less, and water to be treated in the electrolytic gas venting device installed downstream of the electrolytic gas venting device is supplied. This can be achieved by providing a pump for performing the operation. As the flow restricting means, a filter having a large pressure loss may be appropriately selected in addition to the constant flow valve and the orifice, and a pressure reducing valve may be used. As the pump, a pump built in a cup-type beverage maker can be used. That is, when performing gas-liquid separation with the above-described degassing device, the amount of water supplied by the water supply means installed on the downstream side of the electrolytic degassing device (the amount of water supplied from the degassing device to a cup-type beverage maker or the like) The pressure of the water to be treated after passing through the filter is reduced to 1 kgf / cm 2 or less, more preferably at atmospheric pressure or less when the water is passed, by setting the amount of water supplied to the electrolytic gas release device to be smaller than that of the electrolytic gas removing device. Can be. Furthermore, when depressurizing the inside of the electrolytic degassing device by the suction force of the water supply means installed on the downstream side of the electrolytic degassing device, a substantially constant amount of gas is introduced into the degassing device in order to prevent a large flow rate decrease. (For example, about 5 to 50% of the volume in the degassing device) may be constantly accumulated. More efficient gas separation can be performed by reducing the pressure of the water to be treated after passing through the filter in the electrolytic gas venting device to a pressure lower than the atmospheric pressure.

Immediately after installing the in-line chlorine generating electrolytic apparatus of the present invention or immediately after replacing the filter in the electrolytic gas venting apparatus, air exists in the electrolytic gas venting apparatus, and this air enters the beverage production machine. There was a problem that it is not preferable. Therefore, in the in-line chlorine generating electrolyzer of the present invention, an electrolytic gas venting device having an electrolytic gas venting valve is provided downstream of the in-line chlorine generating electrolytic device, and the upstream side of the in-line chlorine generating electrolytic device is Connect to the pipe, connect the downstream side of the in-line chlorine generating electrolyzer to the beverage maker, when the water is allowed to flow, to discharge the air in the pipe including the electrolytic degassing device out of the system, This problem has been solved by a method of controlling an electrolytic gas vent valve that can open the exhaust valve of the electrolytic gas vent device for a certain period of time to discharge air in the electrolytic gas vent device and fill the inside with water. Specifically, when the main switch of the in-line chlorine generation electrolysis apparatus is turned on, the internal air is discharged by hydraulic pressure by opening the electrolytic gas release valve for a certain period of time. At this time, by confirming that the discharge of air + water from the drain tube 49 of FIG. 10 has been changed to the discharge of only water, the inside can be substantially replaced with water. By the way, the in-line chlorine generation electrolysis apparatus of the present invention is used particularly in connection with a post-mix cup-type beverage production apparatus. According to another aspect of the present invention, fine bubbles contained in water treated by the in-line chlorine generation electrolytic device can be separated. That is, raw water such as tap water is purified by passing it through a water purifier having a filter or the like, and this purified water is passed through an electrolytic chlorine generator to produce an effective chlorine component in the purified water, which is then pumped by a pump means through a pipeline. In the beverage supply device to be supplied to the outlet, a filter medium is arranged in an air opening part of a drinking water outlet of the beverage supply apparatus, and fine bubbles of the electrolytic gas contained in the purified water are grown into larger bubbles by passing the filter medium. It is a beverage supply device having bubble separation means. The filter medium is preferably in the form of a tube having a bottom or a cup shape and is preferably used to allow water to flow from the inside toward the outside, but is not particularly limited to this. This makes it easier to separate bubbles after pouring into a cup or the like.

Next, the present invention will be described based on examples, but embodiments of the present invention are not limited to these examples.

Example 1 The in-line chlorine generating electrolysis apparatus of the present invention shown in FIG. 1 was produced. That is, the cylindrical electrode has an outer diameter of 19 mm and an inner diameter of 19 mm.
The inner wall surface of a titanium tube having a length of 17 mm and a length of l = 130 mm was coated with calcined platinum (Excelord R-1000, manufactured by Nippon Carlit). Concentric electrode Outer diameter φ14mm, length l = 1
The surface of a 66 mm titanium rod is covered with calcined platinum (Excelord R-2000, manufactured by Nippon Carlit).

A concentric electrode was inserted into the cylindrical electrode, the concentric electrode was held on the central axis by a connector so that the gap was constant (about 1.5 mm), and was fixed with a titanium screw. Tap water filtered with a cartridge filter and treated with activated carbon (electric conductivity: 300 μS / cm,
(Chlorine ion concentration: 50 ppm) was supplied at a rate of 2 liters / minute, a DC voltage was applied to each electrode, and a current of about 2 A was passed.

The study was conducted by changing the filter or installing a pressure reducing valve to change the conditions. Table 2 shows the results. In Table 2, the pressure 1 is the pressure measured by the pressure gauge 1,
Pressure 2 indicates the pressure measured by the pressure gauge 2 (see FIG. 7), and the evaluation of the gas removal effect is large in the order of ×, Δ, ○, ◎, and 又 は or ◎ is practically acceptable.
