Description

  The present invention provides an extremely high concentration artificial water in a circulation pipe for overheating, keeping warm, and filtering hot water in a bathtub or a foot tub by dissolving carbon dioxide to increase the dissolved concentration of carbon dioxide in the bathtub water or foot tub water. It relates to the technology for producing carbonated springs.

  The present invention jets and / or sprinkles bathtub water or footbath water into a pressure vessel filled with carbon dioxide gas to increase the concentration of dissolved carbon dioxide in the bathtub water or footbath water, and is equivalent to or higher than natural carbonated springs. It is related with the technique which can produce | generate the artificial carbonated spring which has the therapeutic effect of this.

  In addition, the present invention relates to a technology of artificial carbonated spring apparatus particularly suitable for home 24 hour baths and foot bath devices, and a method for realizing a high concentration of carbon dioxide and also having an effective sterilization method for hot water in bathtubs and foot baths. It relates to the device.

Conventionally, carbonated springs obtained by introducing various names of household carbonated spring bath agents are known, but these were made by mixing an organic acid with sodium bicarbonate to generate carbon dioxide gas in heated water. As a technique for producing a carbon dioxide-containing beverage, a high-concentration carbonated water production method in which carbon dioxide gas is blown into cooled water has been known for a long time.
As another method for generating carbonated water, there has been known a method of generating carbonated water for beverages by sprinkling water into a carbon dioxide space and dissolving the carbon dioxide.

  When the human skin is exposed to cold water, capillary contraction occurs to prevent a decrease in body temperature, and blood flow near the skin decreases. In contrast, when the skin comes into contact with heated water containing carbon dioxide at an appropriate temperature, carbon dioxide penetrates under the skin and becomes oxygen-deficient, and a large amount of capillaries that receive this oxygen-deficient signal The entrance of the capillary is opened so that blood can flow. As a result, the blood flow in the vicinity of the skin increases and appears as a flushing phenomenon of the skin. This mechanism is considered to be a bathing effect of carbonated heated water. Here, the saturated dissolved concentration of carbon dioxide at a temperature of about 40 to 42 ° C., which is a suitable temperature for hot springs, is about 1000 ppm.

  Carbonated springs are known around the world as skin-friendly hot springs with excellent heat retention. Not only this, but high concentration carbonated heating water is beginning to be recognized as having a therapeutic effect. For example, as is often seen in diabetics, for example, there is an increasing number of cases in which the wound in the foot worsens and becomes necrotic, which necessitates amputation of the foot. On the other hand, it is thought that the treatment method bathed in the heating water containing high concentration carbonic acid is effective.

  Japanese Unexamined Patent Publication No. 7-313855 proposes a carbonated spring production apparatus using a gas permeable hollow fiber. In this carbonated spring production apparatus, a carbon dioxide gas dissolver containing a hollow fiber and a bathtub are connected by a circulation pipe, hot water pumped from the bathtub by a pump is supplied into the carbon dioxide gas dissolver, and the carbon dioxide gas dissolver is used for carbonation. Gas is dissolved to produce a high-concentration carbonated spring, and this is supplied to the bathtub.

Moreover, this carbonated spring production | generation apparatus has the density | concentration sensor installed in the bathtub, detects the carbon dioxide gas density | concentration of the carbonated spring in a bathtub with this density | concentration sensor, and controls the flow volume of the carbon dioxide gas supplied to a carbon dioxide gas dissolver. Propose that. This carbonated spring production apparatus has a problem that the function of the hollow fiber is likely to be hindered by the contaminants contained in the hot water, and has a drawback that frequent maintenance is required to maintain the initial performance.

  JP-A-11-192421 proposes another type of carbonated spring generating apparatus. This carbonated spring production device stores warm water in a pressure tank, and generates carbon dioxide by dissolving carbon dioxide in warm water by bubbling carbon dioxide gas under pressure in the pressure tank. Is sent to a subsequent gas separator to reduce the pressure to atmospheric pressure and collect carbon dioxide gas from the carbonated spring. When a predetermined time has elapsed, the carbonated spring is supplied from the gas separator to the bathtub.

  The carbonated spring generating device disclosed in Japanese Patent Application Laid-Open No. 11-192421 is a so-called batch type, which performs a step of generating carbonated spring after charging a predetermined amount of hot water into the pressure tank, and then removes the carbonated spring from the pressure tank. The pressure tank is emptied, then hot water is supplied into the empty pressure tank, and the process of generating carbonated springs again is executed. From this, the carbonated springs cannot be generated continuously. .

  Japanese Patent Application Laid-Open No. 6-269483 proposes another type of carbonated spring generating apparatus. This carbonated spring generator supplies carbon dioxide to a pipe that takes hot water out of the bathtub, merges the hot water and carbon dioxide, and then enters the pump through the suction port of the pump. This pump mixes the carbon dioxide and hot water. The carbonated gas is dissolved in warm water to produce a carbonated spring, the carbonated spring sent from the pump is supplied to the tank, the undissolved carbon dioxide gas is recovered in this tank, and then the carbonated spring is returned to the bathtub from the bottom of the tank. Adopted.

In addition, this carbonated spring generating device is provided with a throttle in the pipe between the tank and the bathtub, and opens the electromagnetic valve when the carbonated water level in the tank decreases as the carbon dioxide gas in the tank increases. When the water level of the carbonated spring in the tank increases, the solenoid valve is closed.

  The carbonated spring production device disclosed in Japanese Patent Laid-Open No. 6-269383 is mainly intended to dissolve carbon dioxide gas in warm water by the stirring action of the pump. When a general-purpose pump is adopted, the carbonated spring that can be produced thereby is dissolved. It is difficult to increase the carbon dioxide concentration. That is, if a high concentration carbonated spring is to be produced, a large amount of carbon dioxide gas needs to be combined with warm water upstream of the pump. As a result, the pump sucks a large amount of gas. The pumping action of is inhibited.

  Moreover, although it is not an artificial carbonated spring device, there is a 24-hour bath for home use. In this 24-hour bath, hypochlorous acid is used in a non-diaphragm electrolytic cell in order to suppress the growth of Legionella bacteria, which has been a major problem for some time. There is a product in which an aqueous sodium solution is generated and added to circulating bath water, or filtered with activated carbon or a special filter, and further added with a plurality of filtration and sterilization functions such as hot water sterilization.

Problems to be solved by the invention

  In general, bath water and foot bath water have a lot of hair and scales, and in the method of dissolving carbon dioxide with hollow fibers, the scales and nulls accumulate on the hollow fiber wall surface and entrance, causing clogging and improving the initial performance. In order to maintain, a plurality of filters are required, and maintenance has to be performed frequently.

  Also, when carbon dioxide is bubbled into the bathtub water or foot bath water stored in the tank to dissolve the carbon dioxide gas, a batch system or a circulation system for collecting / re-bubbling the carbon dioxide gas is required. However, the device has become large and cannot be used as a home device.

  In the method of injecting carbon dioxide into the suction side of the pump and dissolving the carbon dioxide in the water and bath water or foot bath water, the pump injects a large amount of carbon dioxide when trying to increase the amount of carbon dioxide dissolved. Since the gas phase in the inside increases and the pump itself does not function, it is difficult to produce a high concentration carbonated spring, and unless excessive carbon dioxide is recovered, the consumption of carbon dioxide will be excessive, and the bathtub will When a large amount of carbon dioxide gas was sent, there was a risk that the bather would cause carbon dioxide poisoning.

  Furthermore, a general 24-hour bath sterilization system is provided with many filters and hot water sterilization devices, which increases the cost of the device and increases the number of consumables, which places a heavy burden on the user.

  In addition, there is a thing in which a non-diaphragm electrolytic cell is provided in the apparatus, a sodium hypochlorite aqueous solution is generated by electrolysis, and the aqueous solution is added to the circulated bath water to have a sterilizing effect. The aqueous sodium hypochlorite solution has a high bactericidal activity when the pH is in a neutral range, so it is necessary to increase the concentration to some extent.

  The guidance of the Ministry of Health, Labor and Welfare is that the chlorine concentration in the bathtub is 0.2 to 0.4 ppm, but the chlorine concentration may decrease depending on the number of bathers and the frequency, so the concentration should be 1.0 ppm. The current situation is that it is set to be slightly weaker, the odor of chlorine becomes stronger, and uncomfortable feeling is felt, and hardship is forced between safety and comfort.

Means for solving the problem

  One of the present invention supplies water from a bathtub or footbath to a pressure vessel filled with carbon dioxide gas by a pump, and jets or sprinkles the supplied bathtub water or footbath water into the pressure vessel. After melting, a circulation system is formed to return to the bathtub or foot tub again, and carbon dioxide is supplied into the pressure vessel, and in order to prevent the carbon dioxide in the pressure vessel from escaping to the bathtub, Footbath water is stored at a predetermined water level at the bottom of the pressure vessel.

  Then, in the middle of the circulation line, add sodium hypochlorite aqueous solution or sodium chlorite aqueous solution, or take out part of bathtub water or footbath water from the circulation line, and add sodium chloride, rock salt or hydrogen sulfide. An electrolytic substance is dissolved with a rock salt containing water, a sodium hypochlorite aqueous solution is generated using a non-diaphragm electrolytic bath, and added again to the bath water and foot bath water of the circulation pipe.

  The added sodium hypochlorite aqueous solution and sodium chlorite aqueous solution become weakly acidic with the bath water and footbath water due to the action of carbon dioxide dissolved in the bath water and footbath water. In comparison, the present invention proposes a method and apparatus that can provide an artificial carbonated spring that has not only a much stronger bactericidal power but also reduced chlorine odor, and is not only comfortable and safe, but also expected to have the original effects of a natural carbonated spring.

  The second of the present invention is a method and apparatus for circulating bath water or foot bath water with a pump for 24 hours to dissolve carbon dioxide gas when necessary, and having a filter and a heater 4 in the circulation line, It has a mechanism to add sodium hypochlorite aqueous solution and sodium chlorite aqueous solution, and has the function to dissolve carbon dioxide gas when necessary and raise the carbon dioxide concentration of bathtub water and footbath water to about 1000 ppm Periodically, add sodium hypochlorite aqueous solution or sodium chlorite aqueous solution to the bath water or foot bath water of the circulation pipeline, and at that time, always dissolve carbon dioxide in the bath water or foot bath water of the circulation pipeline Then, the method and apparatus which raise sterilization power by making bathtub water and foot bathtub water weakly acidic are proposed.

  The third aspect of the present invention is a method and device for circulating bath water or foot bath water with a pump for 24 hours to dissolve carbon dioxide gas when necessary. It has a function to dissolve and raise the carbon dioxide concentration of bathtub water and foot tub water to about 1000 ppm, and it has a pipe line that bypasses the pressure vessel in the circulation pipe, usually reducing the water supply to the pressure vessel, most of it Circulate through the bypass pipe to increase the carbon dioxide concentration and close the bypass pipe only when sterilization is performed, and the bathtub water and foot tub water in the circulation pipe are sent to the pressure vessel. We propose a method and device that reduces power consumption and noise by reducing the number of revolutions of the pump when water is delivered to the pipeline.

An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 shows a typical embodiment of the present invention, which has a filter 2 in the bathtub 1 (of course, it may be provided outside the bathtub and before the pump 3). The bathtub water sucked up from the bathtub 1 by the pump 3 is sucked up from the bathtub 1 and filtered by the filter 2 and then heated by the heater 4 downstream of the pump 3.

  Then, the water is branched and fed to the three pipe lines 101, 102, and 103 at the branch portion 5 downstream of the heater 4. When the electric opening / closing valve 43 is opened, the bathtub water fed to the pipe line 102 dissolves the electrolyte in the electrolyte addition unit 6 containing rock salt or the like, and is fed to the non-diaphragm electrolytic cell 7.

  Further, it is electrolyzed in the non-diaphragm electrolytic cell 7 to become a sodium hypochlorite aqueous solution, and merges with the bath water sucked up from the bathtub by the addition unit 8 through the conduit 110. At this time, if the flow rate flowing through the diaphragmless electrolytic cell 7 is large, the electrolysis efficiency is lowered. Therefore, a throttle 47 is provided in the pipe line 110 to limit the electrolytic flow rate to an appropriate flow rate.

  On the other hand, the bathtub water sent to the pipe line 101 passes through the check valve 49, is sent to the space 9 above the pressure vessel 12, and is injected from the injection hole 10 into the space 11 filled with carbon dioxide gas. Dissolves to become carbonated spring. At this time, the jet flow from the injection hole 10 is such that when the injection from at least two injection holes 10 collides with each other, the injected bath water becomes fine water droplets in the space 11, and the carbon dioxide gas It is easier to dissolve and even better. Moreover, although the injection hole 10 is a mere hole, the spray nozzle which makes the injected injection flow into a mist form may be sufficient.

  The carbon dioxide gas is decompressed by the decompression valves 21 and 22 from the carbon dioxide gas cylinder 19 through the manual valve 20 and then supplied to the space 11 in the pressure vessel 12 at a predetermined pressure equal to or higher than atmospheric pressure.

  The bathtub water containing carbon dioxide gas in the pressure vessel 12 becomes a carbonated spring and is stored at the bottom of the pressure vessel 12, and through the constriction 27 provided in the drainage pipe 106, through the junction 28, and by the drainage pipe 108. Returned to the bathtub.

When the electric opening / closing valve 29 is opened, the bathtub water sent to the pipe 103 joins the drainage from the pressure vessel 12 at the junction 28 and returns to the bathtub through the drain pipe 108.
The check valve 49 is provided in the pressure vessel 12 when the pump 3 is stopped or when the electric on-off valve 29 is opened and the bath water is supplied to the pipe 103 so that the pressure in the pipe 101 decreases. The carbon dioxide gas is prevented from flowing back through the pipe 101.

Next, the preparation operation will be described.
First, the electric opening / closing valves 23, 29, 43 are closed, and the electric opening / closing valve 25 is opened. In the state where the electric open / close valves 43 and 29 of the pipe lines 102 and 103 are closed, all of the bathtub water fed by the pump is fed to the pipe line 101 and further sent to the space 9 of the pressure vessel 12, and the injection hole 10 Is injected into the space 11 and stored in the lower part of the pressure vessel 12.

  Here, when the pressure of the space 11 is atmospheric pressure by the throttle 27 provided in the drain pipe 106, the bathtub water discharged from the pressure vessel is more than the bathtub water jetted and fed from the injection hole 10 to the space 11. When the pressure in the space 11 becomes equal to or higher than the predetermined pressure, the amount of bathtub water discharged from the pressure vessel is larger than the amount of bathtub water sprayed and fed from the injection hole 10 to the space 11.

  As a result, the water level of the carbonated spring in the pressure vessel rises, the float 13 rises, and the air in the space 11 passes through the pipe line 105 and is sent to the drainage pipe line 108 via the merging portion 26. 12 is mixed with the carbonated spring discharged from the tub 12 and discharged into the bathtub 1. A magnet 14 is attached to the float 13, and the limit switch 15, 16, 17, 18 provided on the side surface of the pressure vessel 12 reacts in order by the magnet 14.

  When the limit switch 18 at the highest position reacts, the electric opening / closing valve 25 is closed, the electric opening / closing valve 29 is opened, and the bathtub water fed by the pump 3 is returned to the bathtub through the conduit 103, and the circulation operation is performed. Decrease the pump speed and display that the initial operation is complete. At this time, even if the number of revolutions of the pump is reduced, the resistance of the pipe 105 is small, so the amount of circulating water by the pump does not decrease, and in some cases, the total amount increases compared to when the water is fed to the pressure vessel 12 . Both power consumption and noise are reduced. By this series of operations, the air in the space 11 is completely exhausted.

  At this time, carbon dioxide gas is not supplied to the pressure vessel, but part of the bath water supplied by the pump 3 is also supplied to the pressure vessel 12 via the pipe 101, There is no tub water in the bathroom.

Next, the operation | movement which produces | generates a high concentration carbonated spring is demonstrated.
When a carbonated spring generation button (not shown) is pressed, the rotational speed of the pump is increased to a predetermined value, and the electric on-off valve 29 is closed, and all of the bathtub water fed from the pump 3 is sent to the pressure vessel 12. Send water. Further, when the limit switch 18 is not responding, the electric opening / closing valve 25 is opened and waits until the limit switch 18 reacts. Carbon dioxide gas is supplied to the space 11 in the pressure vessel 12 at a predetermined pressure equal to or higher than atmospheric pressure. Thereby, the gas in the space 11 is substantially only carbon dioxide.

  The water level in the pressure vessel 12 is gradually lowered by the pressure of the supplied carbon dioxide gas, and the float 13 is also lowered accordingly, and reacts in the order of the limit switches 17 and 16. When the limit switch 16 reacts, the electric open / close valve 23 is closed to stop the supply of carbon dioxide gas. Then, the bathtub water injected from the injection hole 10 dissolves the carbon dioxide gas in the space 11, the pressure in the space 11 gradually decreases, and the water level increases again. When the limit switch 17 reacts, the electric open / close valve 23 is opened again to supply carbon dioxide gas. Then, the water level begins to fall again.

  By these operations, the water level in the pressure vessel 12 is maintained between the limit switches 16 and 17, and the generated carbonated spring is returned to the bathtub through the drain lines 106 and 108.

  The bath water is sucked again by the pump 3 and dissolved in the carbon dioxide, and then returned to the bath. By repeating this, the concentration of carbon dioxide in the whole bath water rises and becomes a high concentration carbonated spring.

Next, another operation for generating a high-concentration carbonated spring will be described.
In this case, even if all the bathtub water is sent to the pressure vessel 12 by the pump 3 and the carbon dioxide gas is supplied to the pressure vessel 12 by pressure, the nozzle 27 is provided by the throttle 27 provided in the drain pipe 106. The bathtub water sprayed from 10 becomes larger than the bathtub water drained from the pressure vessel 12.

  When a carbonated spring generation button (not shown) is pressed, the pump speed is increased to a predetermined value. If the limit switch 18 is not responding, the electric open / close valve 25 is opened, waits until the limit switch 18 reacts, the electric open / close valve 25 is closed, and the electric open / close valve 23 is opened from the carbon dioxide cylinder 19. Carbon dioxide gas is supplied to the space 11 in the pressure vessel 12 at a predetermined pressure equal to or higher than atmospheric pressure, and the electric open / close valve 29 is appropriately opened to supply water to the pipe 103.

  Then, since the amount of bathtub water sent to the pressure vessel 12 is reduced, the water level in the pressure vessel 12 is gradually lowered, and the float 13 is also lowered accordingly, and reacts in the order of the limit switches 17 and 16. When the limit switch 16 reacts, the electric open / close valve 29 is closed and all the bathtub water supplied by the pump 3 is supplied to the pressure vessel 12. As a result, the amount of bathtub water fed to the pressure vessel 12 increases and the water level rises again. When the limit switch 17 reacts, the electric on-off valve 29 is appropriately opened again to send the bath water to the pipe 103. Then, the water level begins to fall again.

  By these operations, the water level in the pressure vessel 12 is maintained between the limit switches 16 and 17, and the generated carbonated spring is returned to the bathtub through the drain lines 106 and 108.

  The bathtub water is sucked by the pump 3 and is returned to the bathtub after dissolving the carbon dioxide gas. By repeating this, the carbon dioxide gas concentration of the whole bathtub water rises and becomes a high concentration carbonated spring.

  Further, in the high-concentration carbonated spring generation state in the above two operations, the electric on-off valve 43 is always opened for a predetermined time to generate a sodium hypochlorite aqueous solution and add it to the bath water to sterilize the bath water. Good to do.

  Separately, in order to maintain the sterilized state of the bath water, the sterilization operation described below is performed at predetermined time intervals. That is, while increasing the rotation speed of the pump to a predetermined rotation, the electric on-off valve 29 is closed, and all the bath water supplied from the pump 3 is supplied to the pressure vessel 12. Further, when the limit switch 18 is not responding, the electric opening / closing valve 25 is opened, waits until the limit switch 18 reacts, the electric opening / closing valve 25 is closed, and the electric opening / closing valves 23 and 43 are opened. In addition, carbon dioxide gas is supplied from the carbon dioxide gas cylinder 19 to the space 11 in the pressure vessel 12 at a predetermined pressure equal to or higher than atmospheric pressure, and a part of the bath water is sent to the conduit 102 and the sodium hypochlorite aqueous solution in the diaphragm electrolyzer. Is added to the bath water by the addition unit 8.

  The bath water to which the sodium hypochlorite aqueous solution has been added is sent to the pressure vessel 12 by the pump 3, and becomes carbonic acid by being added with carbon dioxide gas. The bactericidal effect is enhanced and the bath water is returned to the bath again. At this time, the water level in the pressure vessel 12 is maintained by either of the two methods.

  In this case, the purpose is not to produce a high-concentration carbonated spring but to make the bath water weakly acidic. Therefore, after a predetermined time has elapsed, the pump speed is lowered and the electric on-off valve 23 is closed to close the carbonated water. The supply of gas is stopped, and the electric on-off valve 29 is opened to return to the circulation operation in which most of the bath water is sent to the pipe 103.

  However, the electric on-off valve 43 is kept open and the addition of the sodium hypochlorite aqueous solution is continued. Then, after a predetermined time has passed, the electric on-off valve 43 is closed to stop the generation and addition of the sodium hypochlorite aqueous solution.

  Of course, if necessary, the carbonated spring may be generated while the sodium hypochlorite aqueous solution is added, or the carbonated spring may be intermittently generated. By this sterilization operation, the bathtub water is always sterilized and can be kept clean.

Next, FIG. 2 is a simplified embodiment in the case where the pipe 103 in FIG. 1 is not provided.
In this case, when the electric on-off valve 43 provided in the pipe line 202 connected to the non-diaphragm electrolytic cell 7 is closed, all the bath water fed by the pump 3 is sent to the pressure vessel 12.

  The generation of the sodium hypochlorite aqueous solution in the diaphragmless electrolytic cell, the supply of carbon dioxide gas to the pressure vessel 12, and the injection operation through the injection hole 10 into the pressure vessel 12 are basically the same as those described in FIG. The same.

Next, the preparation operation will be described.
First, the electric on-off valves 23 and 43 are closed, and the electric equipment on-off valve 25 is opened. In the state where the electric opening / closing valve 43 of the pipe line 102 is closed, all the bathtub water fed by the pump is fed to the pipe line 101 and further sent to the space 9 of the pressure vessel 12 and injected into the space 11 from the injection hole 10. Water is fed and stored in the lower part of the pressure vessel 12.

  Here, when the pressure of the space 11 is atmospheric pressure by the throttle 27 provided in the drain pipe 106, the bathtub water discharged from the pressure vessel is more than the bathtub water jetted and fed from the injection hole 10 to the space 11. When the pressure in the space 11 becomes equal to or higher than the predetermined pressure, the amount of bathtub water discharged from the pressure vessel is larger than the amount of bathtub water sprayed and fed from the injection hole 10 to the space 11.

  As a result, the water level of the carbonated spring in the pressure vessel rises, the float 13 rises, and the air in the space 11 passes through the pipe line 105 and is sent to the drainage pipe line 108 via the merging portion 26. 12 is mixed with the carbonated spring discharged from the tub 12 and discharged into the bathtub 1. A magnet 14 is attached to the float 13, and the limit switch 15, 16, 17, 18 provided on the side surface of the pressure vessel 12 reacts in order by the magnet 14. As a result, the air in the space 11 is completely exhausted. When the limit switch 18 reacts, the electric open / close valve 25 is closed to indicate that the initial operation has been completed.

Next, the operation | movement which produces | generates a high concentration carbonated spring is demonstrated.
When a carbonated spring generation button (not shown) is pressed, if the limit switch 18 is not responding, the electric open / close valve 25 is opened, waits until the limit switch 18 reacts, and the electric open / close valve 25 is closed. At the same time, the electric open / close valve 23 is opened, and carbon dioxide is supplied from the carbon dioxide cylinder 19 to the space 11 in the pressure vessel 12 at a predetermined pressure equal to or higher than atmospheric pressure. Thereby, the gas in the space 11 is substantially only carbon dioxide.

  The water level in the pressure vessel 12 is gradually lowered by the pressure of the supplied carbon dioxide gas, and the float 13 is also lowered accordingly, and reacts in the order of the limit switches 17 and 16. When the limit switch 16 reacts, the electric open / close valve 23 is closed to stop the supply of carbon dioxide gas. Then, the bathtub water injected from the injection hole 10 dissolves the carbon dioxide gas in the space 11, the pressure in the space 11 gradually decreases, and the water level increases again. When the limit switch 17 reacts, the electric open / close valve 23 is opened again to supply carbon dioxide gas. Then, the water level begins to fall again.

  By these operations, the water level in the pressure vessel 12 is maintained between the limit switches 16 and 17, and the generated carbonated spring is returned to the bathtub through the drain lines 106 and 108.

  The bath water is sucked again by the pump 3 and is returned to the bath after dissolving the carbon dioxide gas. By repeating this, the carbon dioxide gas concentration in the whole bath hot water rises to become a high-concentration carbonated spring.

  Moreover, in the state of high concentration carbonated spring generation in the above operation, the electric on-off valve 43 is always opened for a predetermined time, and a sodium hypochlorite aqueous solution is generated and added to the bath water to sterilize the bath water. Good to do.

Separately, in order to maintain the sterilized state of the bath water, the sterilization operation described below is performed at predetermined time intervals. That is, when the limit switch 18 is not responding, the electric opening / closing valve 25 is opened, waiting until the limit switch 18 reacts, the electric opening / closing valve 25 is closed, and the electric opening / closing valves 23 and 43 are opened. In addition, carbon dioxide gas is supplied from the carbon dioxide gas cylinder 19 to the space 11 in the pressure vessel 12 at a predetermined pressure equal to or higher than atmospheric pressure, and a part of the bath water is sent to the conduit 102 and the sodium hypochlorite aqueous solution in the diaphragm electrolyzer. Is added to the bath water by the addition unit 8.
The bath water to which the sodium hypochlorite aqueous solution has been added is sent to the pressure vessel 12 by the pump 3, and becomes carbonic acid by being added with carbon dioxide gas. The bactericidal effect is enhanced and the bath water is returned to the bath again.

  In this case, the purpose is not to produce a high-concentration carbonated spring, but to make the bath water weakly acidic. Therefore, after a predetermined time has elapsed, the electric on-off valve 23 is closed to stop the supply of carbon dioxide gas.

  However, the electric on-off valve 43 is kept open and the addition of the sodium hypochlorite aqueous solution is continued. Then, after a predetermined time has elapsed, the electric on-off valve 43 is closed to stop the generation and addition of the sodium hypochlorite aqueous solution.

  Of course, if necessary, the carbon dioxide gas may be always supplied during the addition of the sodium hypochlorite aqueous solution, or the carbonated spring may be completely generated. By this sterilization operation, the hot water in the bathtub is always sterilized and can be kept clean.

The following items are common to the embodiments of FIGS.
If the water level in the pressure vessel 12 rises during the carbonated spring generation operation and the limit switch 18 reacts, it also has a function of displaying a carbon dioxide supply shortage warning that the pressure of the supplied carbon dioxide gas is insufficient.

  In addition, an elastic body 45 is provided at the bottom of the float 13, and even if the water level in the pressure vessel 12 drops and the float falls to the bottom of the pressure vessel 12, the elastic body 45 allows the drain 46 at the bottom of the pressure vessel to be opened. It closes and prevents the carbon dioxide gas in the pressure vessel 12 from being discharged into the bathtub 1.

  Further, in the state where the sodium hypochlorite aqueous solution is generated in the diaphragmless electrolytic cell, the electrolytic current is detected, and when the current is lower than a predetermined current location, the electrolyte is less dissolved, that is, the electrolyte There is also a function of displaying that there is no electrolyte added portion.

  Furthermore, it has a function of performing self-cleaning of the electrode by periodically changing the polarity applied to the electrode of the diaphragm membrane electrolytic cell. Further, when rock salt containing hydrogen sulfide is used as the electrolyte, not only carbon dioxide gas but also carbonate spring in which sulfide gas is slightly dissolved can be generated, and further, the bathing effect can be expected to increase.

The invention's effect

  According to the present invention, even hot water that is dirty in a sense, such as bath water, can be circulated without causing clogging to dissolve carbon dioxide gas, and a high-concentration carbonated spring can be easily produced. Maintenance is easy and the initial performance can be maintained for a long time.

  In addition, the sodium hypochlorite aqueous solution and the chlorous acid aqueous solution are alkaline per se, and the bactericidal power is not so strong, so a sufficient effect cannot be obtained unless it is added in a large amount. When used with warm water in which carbon dioxide gas is dissolved, a weakly acidic hypochlorous acid aqueous solution or chlorous acid aqueous solution is obtained, and a sufficient bactericidal effect can be obtained even at a low concentration, and there is almost no unpleasant chlorine odor.

  And even when the bath water is kept warm while being circulated and filtered through a heater and a filter such as a 24-hour bath, since the hot water is always sterilized by strong hypochlorous acid or chlorous acid, Propagation of bacteria in the road is also prevented, and it is not necessary to sterilize the filter or pipe with hot water, or to change the filter frequently using multiple filters.

  In addition, except when generating high-concentration carbonated springs, circulation through a bypass line allows sufficient circulation even if the pump discharge pressure is lowered. You can drive.

  Therefore, according to the present invention, a clean bath that has been kept warm for 24 hours even in ordinary homes can be easily converted to a high-concentration carbonated spring whenever necessary, and is an indispensable product for the modern society where aging and stress are advancing. Can be provided at low cost.
