Description

  The present invention relates to a sauna bath (sauna bath) or a Finnish steam bath referred to simply as a sauna, and more particularly, to a bubble sauna apparatus that jets bubbles into the bathroom and a bubble sauna using the same.

  In addition to exhausting fatigue substances and promoting weight loss due to sweating, saunas have been reported to offer benefits such as relaxation by improving blood flow, feeling free from stress, and being able to sleep well. Sauna is roughly classified into dry type and wet type. The dry type is called dry sauna, and the internal temperature is as high as 80 ° C to 100 ° C. The wet type is also called a mist sauna, and the internal temperature is about 40 to 50 ° C., and the humidity is near 100%.

  Conventionally, it is known that bubbles are generated by jetting a gas in a water tank such as a bathtub, and an apparatus using hydrogen gas as a gas jetted in water is described in Patent Document 1. In other words, baths in which hydrogen gas is supplied into bath water, so-called hydrogen baths, have recently attracted attention as baths that exhibit beauty effects in addition to anti-aging effects.

  In addition, in a mist sauna device configured to generate mist from a nozzle with air pressure and hot water supply pressure provided from an air pump provided outside the bathroom, generation of hydrogen water mist and further sufficient effect as hydrogen water is obtained. Patent Document 2 describes that hydrogen water mist in which hydrogen gas is dissolved at a high concentration to such an extent that can be produced.

JP 2012-75744 A JP 2017-6272 A

  In the above-described conventional technology, what is described in Patent Document 1 is a so-called hydrogen bath, and it is said that a bubble of hydrogen gives a refreshing and moist feeling, and many benefits are obtained in terms of health and beauty. However, since it is not a mist sauna device, it is difficult to say that the mist wraps around the whole body and enjoys the effects of promoting sweating, promoting blood flow, moisturizing the skin, refreshing and relaxing by more enjoying bathing time.

  The thing of patent document 2 uses hydrogen water as the original water of the mist ejected in order to make a hydrogen atmosphere in the mist sauna, and the hydrogen gas supplied from the hydrogen gas supply source is inside the casing. In this case, the hydrogen gas is only dissolved in water while being kept at around normal temperature. When the fine water droplets ejected by the mist spray nozzle move in the air, the dissolved hydrogen gas escapes. Therefore, even if high-concentration hydrogen water is released into the space as fine water droplets, the hydrogen concentration is not detected in the water droplets when they are applied to the skin or the like. In other words, even if hydrogen water is simply sprayed into the bathroom, you will feel that you have been exposed to mist of hydrogen water, but it is not sufficient to obtain the effect of hydrogen water.

  An object of the present invention is to provide a new bubble sauna combining a bubble and a sauna. As a result, it is possible to experience a new sense that bubbles are shed on the skin, and it is possible to taste a novel sense that many bubbles are floating in the sauna room visually.

  In addition, since the gas in the bubble is changed to hydrogen, when the bubble touches and repels the skin, a high concentration of hydrogen comes into contact with the skin. For this reason, not only the effects of saunas such as promoting sweating, promoting blood flow, moisturizing skin, refreshing and relaxing, but also the effects of hydrogen, which has been attracting attention in recent years, Anti-aging effects such as anti-oxidation of hair can also be expected.

  In order to achieve the above object, the present invention provides a bubble sauna apparatus in which a bubble is floated in a bathroom. The heating / humidifying means for heating the bathroom and increasing the humidity; A solution tank for storing a solution containing an agent as a bubble solution; and a bubble generation nozzle for ejecting a bubble containing gas from the bubble solution into the bathroom.

Further, the present invention provides a bubble sauna apparatus in which a bathroom is a sauna bath, a hydrogen gas generator that supplies hydrogen gas, a solution tank that stores a solution containing a surfactant as a bubble solution, and the bubble solution. A bubble generating nozzle that ejects hydrogen bubbles containing the hydrogen gas into the bathroom.
Here, as the gas to be included in the bubble, hydrogen is desirable, but other gases that are harmless to the body, for example, inert gas (helium, neon, argon, krypton, xenon, radon), nitrogen, etc. are selected. May be. In that case, those gas generators and those gas storage tanks can be used as gas supply means instead of the hydrogen gas generator.

  Thereby, since it becomes a sauna bath which ejects the hydrogen bubble which included hydrogen gas in a bathroom, hydrogen gas can be reliably transmitted to the skin etc. of the person who entered the sauna. Furthermore, it is accompanied with a visual effect, and the good influence on the human body by hydrogen gas can be given more effectively. Moreover, when the hydrogen bubble hits the skin and bounces, the crackling or swooshing feeling when it bounces is like a light massage.

  The present invention may further include an oxygen gas generation device that supplies oxygen gas, and the bubble generation nozzle may be configured to eject a bubble containing oxygen generated by the oxygen gas generation device.

The block diagram which shows the hot water supply equipment by one Embodiment by this invention Schematic showing a bubble generator according to an embodiment of the present invention. Schematic which shows the bubble sauna apparatus which concerns on other embodiment by this invention.

  Hereinafter, Embodiment 1 of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic view showing the entire bubble sauna using the bubble generator 40, and the hydrogen gas generator 1 is provided in the bubble sauna device 50 for generating the hydrogen water mist 62 and the hydrogen bubble 61. ing. Reference numeral 60 denotes a bathroom (sauna room), in which hydrogen water mist 62 and hydrogen bubbles 61 are sprayed by the bubble sauna device 50.

  Here, since the inside of the bathroom 60 may be in a high humidity state, it may be just water mist instead of hydrogen water mist, but in order to obtain the effect of hydrogen, hydrogen water mist may be used. preferable. Further, instead of hydrogen water mist, water vapor can be generated so that water vapor is introduced into the bathroom 60 instead of hydrogen water mist.

  FIG. 2 is a table showing characteristics of the dry sauna and the mist sauna. Sauna is roughly classified into dry (dry sauna) and wet (mist sauna), and the comparison results are shown. The dry type is called a dry sauna, and the internal temperature is as high as 80 to 100 ° C. The wet type is also called a mist sauna, and the internal temperature is around 40 ° C. (or 40-50 ° C.) and the humidity is close to 100%. Moreover, the dry sauna has a high risk of ignition in the bathroom 60 and is low in the mist sauna.

  Furthermore, when hydrogen gas is sent to the bathroom 60 as a hydrogen sauna in which hydrogen is introduced into the bathroom 60, it is important how the hydrogen gas is supplied into the interior. In a dry sauna, the interior of the bathroom 60 is a dry atmosphere and is hot, so hydrogen gas is a flammable gas, although it is not a temperature at which hydrogen gas ignites spontaneously. Since it cannot be said that it is not possible, wet processing with low internal temperature and high humidity is desirable. In addition, since dry saunas are hot and have low humidity, the addition of hydrogen gas may cause irritation to some people and may not fit or cause strain on the body.

  On the other hand, in a mist sauna, hot water is sprayed with warm air from a nozzle built in the device. That is, a mist generating device is used as a heating / high humidity means for warming the bathroom to a high humidity state. In the present invention, it is preferable to use a mist generating device as the heating / humidification means, but an indoor heating device or a humidification device that is usually used as heating / humidification means in a wet sauna can also be used.

  And as the name suggests, you can enjoy the sauna in a “mist”, so there is little temperature stimulation and thirst, and there is no breathing. Usually, the size of the water sprayed in the mist sauna is intermediate between “Kiri” and “Fog”, and the water droplet diameter is about 50 μm to 300 μm. The main points of the mist sauna are “Sweating”, “Washing”, “Moisturizing” and “Heat keeping”, and it is said that it is effective for sweating even if it is bathed for 10 minutes. It is also known that the “mist bath” increases by 150, that is, 1.5 times or more, when the amount of perspiration in normal bathing (whole body bathing) is 100.

  As a quick method for making a hydrogen atmosphere inside the mist sauna, there is a method in which the original water of the mist to be ejected is hydrogen water. However, hydrogen is generated with a hydrogen gas generator to produce high-concentration hydrogen water, and a dissolved hydrogen concentration meter collects water droplets of fine hydrogen water that strikes the skin etc. by spraying in a spray or humidifier. No hydrogen was detected even when an experiment was conducted to measure the hydrogen concentration. In other words, it was found that the fine water droplets ejected escaped the dissolved hydrogen gas when moving in the air. In addition, gas molecules in the liquid move more actively as the temperature rises, and therefore easily move out of the liquid. Therefore, when the water in contact with the hydrogen gas is heated to a high temperature of about 50 ° C., the amount of hydrogen gas that can be dissolved in the water is increased. It became less.

  Therefore, a bubble containing hydrogen gas (such as a soap bubble in which hydrogen gas is contained) is created, and the bubble is ejected into the bathroom 60 to float the bubble in the bathroom 60. Thereby, the hydrogen gas was sent into the mist sauna, and the bubble sauna device 50 that more effectively exerts a good influence on the human body by the hydrogen gas to the person who entered the sauna was obtained.

  The hydrogen bubble 61 encapsulating hydrogen gas has a diameter of 0.2 to 2 mm, preferably about 0.5 to 1 mm, in a bubble generator 40 that produces fine bubble-shaped bubbles from a solution containing a surfactant. The hydrogen bubble 61 was made, and the hydrogen gas generated by the hydrogen gas generator 1 was put into the hydrogen bubble 61.

  As described above, since the bubbles suitably used in the present invention are small (diameter: 0.2-2 mm, preferably about 0.5-1 mm), the amount of water occupying the volume is large and becomes heavy and floats gently. Although it becomes difficult, it becomes easy to float by enclosing hydrogen, and it becomes possible to float in the bathroom 60 for a long time.

  The bubble sauna includes a bathroom 60 and a bubble sauna device 50. The bubble sauna device 50 includes the hydrogen gas generation device 1 that electrolyzes water and supplies hydrogen gas, and has a simple structure suitable for installation and maintenance, and can be manufactured at low cost. The hydrogen gas generated by the hydrogen gas generator 1 is introduced into the hot water supply facility 10 through the discharge pipe 55, and the hot water supply facility 10 supplies water and hot water at 40 to 50 ° C.

  Accordingly, in the hot water supply facility 10, water is heated to a predetermined temperature of 40 to 50 ° C., and hydrogen water in which the introduced hydrogen gas is dissolved is generated. The generated hydrogen water is branched, one is led to the bubble generator 40 by the hydrogen water supply pipe 52, and the other is led to the hydrogen water tank 41 by the hydrogen water supply pipe 51. In the hydrogen water tank 41, hydrogen water mixed with the hydrogen gas generated by the hydrogen gas generator 1 and dissolved in the hydrogen gas is stored.

  The hydrogen gas supplied from the hydrogen gas generator 1 is directly supplied to the bubble generation nozzle 53 of the bubble generator 40 through the hydrogen gas supply pipe 56. The bubble generator 40 pressurizes the air and the hydrogen gas supplied from the hydrogen gas generator 1 and ejects the hydrogen gas from the bubble generation nozzle 53 into the bathroom 60.

  At that time, bubbles are bubbled together with a bubble solution that is an aqueous solution containing a surfactant stored in the solution tank 45, so that bubbles containing bubbles are formed, and a large number of bubbles are ejected into the bathroom 60. Is done. The bubble generation nozzle 53 is installed slightly downward from the middle in the height direction toward the interior of the space of the bathroom 60.

  On the other hand, the hydrogen water in the hydrogen water tank 41 is sprayed into the bathroom 60 as a hydrogen water mist 62 from the spray nozzle 42. The spray nozzle 42 is provided with a minute hole at the tip, and is installed at a position higher than the bubble generation nozzle 53 in the middle in the height direction toward the interior of the bathroom 60. When mist is used, hydrogen gas escapes, but tap water aerated with hydrogen has a reduced oxidation-reduction potential and becomes water that is gentle to the skin.

  The size of the bathroom 60 is, for example, a width of 2 m, a height of 2 m, and a depth of about 1.6 m, the temperature in the bathroom is 30 to 50 ° C., the humidity is 90% or more, and the amount of water used is about 30 liters per hour. Yes, materials that are used for general bathrooms can be used. As the inner wall material of the bathroom 60, for example, resin, ceramics, stainless steel, enamel, and wood are preferable. In addition, the bathroom 60 is provided with an entrance, a ventilation opening, a window, and the like as necessary. Any of them should have high fireproof performance.

  The hydrogen water supply pipes 51 and 52 do not leak hydrogen water flowing through the inside thereof and have a mechanical strength that can withstand the pressure. Specifically, generally used gas piping is applied, and as a material, for example, a metal such as stainless steel, a resin, a metal whose inner wall is covered with a resin, or the like is desirable. The spray nozzle 42 and the bubble generation nozzle 53 are required to have heat resistance, and a metal such as stainless steel is preferable.

  43 is a combustible gas detector that detects the hydrogen gas concentration, and is installed in the bathroom 60. Since the hydrogen gas is a combustible gas, safety such as the hydrogen gas concentration in the bathroom 60 and the hydrogen gas concentration of the mist is confirmed, and if the concentration rises above a predetermined value, the hydrogen gas generator 1 Stop supplying hydrogen gas. Here, although the combustible gas detector 43 is described as being installed in the lower part of the bathroom 60 in FIG. 1, it is preferably installed in the upper part. This is because hydrogen gas is light and accumulates on top.

  In addition, although the hydrogen gas generator 1 demonstrated as what can electrolyze water and can supply hydrogen gas, it is good also as a type provided with the hydrogen gas tank. However, when a hydrogen gas tank is used, it takes time to supply hydrogen, and the maintenance cost of the hydrogen gas tank is also required. On the other hand, if it is set as the hydrogen gas generator 1 which can electrolyze water and can supply hydrogen gas, it will be a simple structure suitable for installation and maintenance, and a low-cost sauna apparatus will be attained.

  The power supply unit 3 applies a DC voltage between the hydrogen electrode 22 and the oxygen electrode 23 in the electrode unit 2 to supply DC electricity. In addition, the power supply unit 3 supplies electricity at a necessary voltage level to the control unit 4, the display unit 5, sensors / instruments, and the like shown in FIG. 3. For example, the power supply unit 3 is connected to a commercial power source (for example, single-phase AC 100 V) or the like drawn from the outside, and converts the commercial power source into electricity at a necessary DC level of the hydrogen gas generator 1. If the power consumption is 130 W, 300 CC of hydrogen gas with a generated gas purity of 99.999% can be supplied per minute.

  The distilled water tank 11 stores distilled water in order to supply the electrode unit 2 with water for electrolysis. Further, the distilled water tank 11 is provided with a flow path so as to be able to receive the water circulated and returned from the gas-liquid separator 12 and the electrode unit 2.

  The gas-liquid separator 12 separates water and hydrogen gas from water containing hydrogen gas discharged from the electrode unit 2. After separating water and hydrogen gas, the gas-liquid separator 12 returns the water to the distilled water tank 11 and discharges the hydrogen gas to the dry filter 13.

  The drying filter 13 passes the hydrogen gas containing moisture discharged from the gas-liquid separator 12, removes the moisture with a filter while allowing the hydrogen gas to pass, and dries it. The drying filter 13 discharges the dried hydrogen gas through the hydrogen gas discharge port of the hydrogen gas generator 1.

  The hydrogen meter 114 is provided at the hydrogen gas outlet. The hydrogen meter 114 measures the flow rate of hydrogen gas through the hydrogen gas outlet. The hydrogen meter 114 sends the measurement data to the control unit 4. For example, the control unit 4 converts the amount of hydrogen gas generated based on the measurement data.

The liquid level sensor 111 measures the level of distilled water stored in the distilled water tank 11. Thereby, the remaining amount of distilled water can be detected. The liquid level sensor 111 sends measurement data to the control unit 4.
The electrode current detection sensor 112 measures the current flowing through the electrode unit 2. The electrode current detection sensor 112 sends measurement data to the control unit 4.

  The hydrogen pressure sensor 113 is provided at the discharge port of the drying filter 13 and measures the pressure of the hydrogen gas discharged from the drying filter 13. The hydrogen pressure sensor 113 sends measurement data to the control unit 4. Thereby, the gas generation pressure is adjusted to 0.4 MPa.

  The control unit 4 collects measurement data measured from various sensors, and monitors each state (hydrogen gas amount, remaining distilled water, electrode current, etc.) based on the collected measurement data. For example, the control unit 4 is provided with a protection function for stopping the supply of electricity from the power supply unit 3 when the electrode current detection sensor 112 detects an overcurrent. The control unit 4 includes a memory, a CPU, and the like, and the monitoring / protection / control operation process is executed by a program in which a monitoring / protection / control function is incorporated.

The hydrogen electrode 22 is a cathode made of an electrode material for water electrolysis having a hydrogen electrode catalyst layer not containing a platinum group element. On the hydrogen electrode 22 side, for example, hydrogen gas (H ₂ ) is discharged through a hydrogen discharge connection portion 31 connected to an external hydrogen supply destination and a hydrogen storage portion 25 that discharges hydrogen gas to the hydrogen gas supply destination. Is done.

At the hydrogen electrode 22, the generated hydrogen ions (H ⁺ ) and electrons (e ⁻ ) react by 2H ⁺ + 2e ⁻ → H ₂ to generate hydrogen gas. At this time, hydrogen ions generated on the oxygen electrode 23 side pass through the inside of the PEM film 24, and electrons moving from the oxygen electrode 23 are connected to the electrode connection terminal 35 and the power supply unit 3 connected to the hydrogen electrode 22. And move to the hydrogen electrode 22.

  FIG. 5 is a block diagram showing the hot water supply facility 10 that performs from the water supply to the hydrogen water tank 41 that stores the hydrogen water, and the stored hydrogen water is sprayed into the bathroom 60 as the hydrogen water mist 62 from the spray nozzle 42. The Further, hydrogen water may be supplied to the bubble generator 40.

  The hydrogen gas discharge on-off valve 15 is a valve that is provided on the piping path of the hydrogen gas discharge pipe and that can be opened and closed for supplying or stopping the hydrogen gas discharged from the hydrogen gas generator 1. In the hydrogen gas discharge on / off valve 15, when the valve is closed in order to stop the supply of hydrogen gas, normal hot water supply is supplied from the hot water supply device 7 to the hydrogen water tank 41.

  The discharge pump 16 is a pump for sending the hydrogen gas discharged from the hydrogen gas generator 1 to the mixing unit 72. The discharge pump 16 is connected to the hydrogen gas generator 1 through a hydrogen gas discharge pipe. The discharge pump 16 can suck the hydrogen gas generated by the hydrogen gas generator 1 and efficiently discharge the hydrogen gas from the hydrogen gas generator 1.

To do. The mixing unit 72 discharges the hot water mixed with the hydrogen gas to the hydrogen water tank 41 through the hot water supply pipe.

  FIG. 6 is a schematic diagram showing the bubble generator 40, which mainly includes a solution tank 45 and a bubble generation nozzle 53. In the solution tank 45, a solution in which a small amount of a surfactant is mixed with hydrogen water is stored in order to generate hydrogen bubbles 61 containing hydrogen gas.

  Various gases can be selected in the bubble, and hydrogen gas generated by the hydrogen gas generator 1 is added. As a result, hydrogen gas 61 containing hydrogen gas is made and ejected into the space of the bathroom 60 so that the hydrogen gas is surely and safely sent into the bathroom 60, and further to the human body by hydrogen gas to the person who entered the sauna Has a good impact.

  Here, oxygen may be put in the bubble instead of hydrogen. In the hydrogen gas generator 1, since water is electrolyzed to generate hydrogen, oxygen is also generated. That is, the hydrogen gas generator 1 also functions as an oxygen gas generator. Therefore, it is possible to supply oxygen instead of hydrogen simply by changing the piping of the hydrogen gas generator 1. Therefore, an oxygen bubble containing oxygen can be formed, so that the oxygen bubble can be put in the bathroom 60.

  In recent years, the positive influence of oxygen on the body has attracted attention, and oxygen capsules and oxygen bars have been made. It is said that there is a fatigue recovery effect by sucking oxygen having a higher concentration than in the air. By using oxygen bubbles, a sauna that can be expected to have an effect like an oxygen capsule or an oxygen bar can be obtained.

Furthermore, oxygen and hydrogen formed by the hydrogen gas generator 1 may be mixed to form a bubble containing a mixed gas of oxygen and hydrogen, and the bubble may be placed in the bathroom 60. Furthermore, both an oxygen bubble containing oxygen and a hydrogen bubble containing hydrogen may be produced, and both may be introduced into the bathroom 60. Both can be easily realized by changing the piping of the hydrogen gas generator 1 so as to mix hydrogen and oxygen, or by using a switching cock for hydrogen introduction and oxygen introduction.
Thereby, it can be set as the sauna expected to have both the effect of hydrogen and the effect of oxygen.

  By adding a surfactant to the hydrogen water, it is possible to make a thin film by reducing the coagulation ability of the hydrogen water. A round hydrogen bubble 61 that is hard to break is formed by weakening the surface tension of the hydrogen water with a surfactant and stretching it into a thin film.

  The surfactant is used to form a thin film of the hydrogen bubble 61, and is preferably a natural surfactant that is harmless and gentle to the body. For example, egg yolk lecithin, soybean lecithin, and saponin contained in plants. Amino acid-based surfactants made by reacting amino acids with naturally occurring higher fatty acids that are mildly irritating and gentle to the scalp, soap-based interfaces made by reacting naturally-derived oils and fats, and fatty acids with alkalis An activator or the like may be used.

  The bubble generation nozzle 53 includes, for example, three communication pipes 53-1, 53-2, and 53-3, and the communication pipe 53-1 is inserted into the solution tank 45. Hydrogen gas generated by the hydrogen gas generator 1 is supplied to the communication pipe 53-2. The pressure-adjusted air is supplied to the communication pipe 53-3. As a result, a bubble having a diameter of 0.2 to 2 mm, desirably about 0.5 to 1 mm, is bubbled from the bubble generation nozzle 53 with hydrogen water, and a bubble in which the gas is hydrogen gas is sprayed into the bathroom.

  The size of the hydrogen bubble 61 and the amount of hydrogen gas contained therein are adjusted so that the hydrogen bubble 61 does not immediately go to the ceiling of the bathroom 60 and does not fall immediately, but floats in the bathroom 60. As a result of the experiment, the amount of air used is 2 to 4 (preferably 2.7) L / min, the amount of hydrogen gas used is 200 to 400 (preferably 300) L / min, and hydrogen balls 61 are generated. It was appropriate from a bodily sensation to set the number to about 1000 to 2000 per minute.

  Since the hydrogen bubble 61 floats in the bathroom 60, it has a visually relaxing effect. Further, when the hydrogen bubble 61 hits the skin, the hydrogen gas which is bounced and is contained comes out and comes into contact with the skin. Also, when you can play it, it feels like a light massage.

  The color of the hydrogen bubble 61 has a deep relationship with the thickness of the film, and is the thinnest among those visible to the naked eye. Since this thin film has a thickness close to the wavelength of light, white light is applied to the hydrogen bubble 61 with, for example, an LED bulb (not shown). Thereby, a part of the light is reflected on the surface of the soap film and the other is reflected on the back side. The wavelengths of the two reflected lights interfere with each other, resulting in a bright color, for example, a rainbow color. Then, the color of the hydrogen bubble 61 can be changed depending on whether the wavelength of light increases due to interference or cancels out. This color change can further enhance the visual relaxation effect. Of course, the visual effect can be enhanced by switching to monochromatic light or a plurality of monochromatic lights instead of white light.

  FIG. 7 is a schematic view showing the entire bubble sauna apparatus 50 according to the second embodiment which is another embodiment of the present invention. For the first embodiment shown in FIG. 1, the hydrogen water tank 41 for generating the hydrogen water mist 62 and the hydrogen bubble 61 is shared, and the bubble water generating device 40 uses the hydrogen water mist 62 and the hydrogen bubble 61. Is sprayed into the bathroom 60. The bubble sauna device 50 is provided with a hydrogen gas generator 1. Reference numeral 60 denotes a bathroom in which hydrogen water mist 62 and hydrogen bubbles 61 are sprayed therein by the bubble sauna device 50.

  The hydrogen gas generated by the hydrogen gas generator 1 is introduced into the hot water supply facility 10 through the discharge pipe 55, and water supply and hot water supply at 40 to 50 ° C. are performed. The hydrogen water supply pipe 52 leads to a hydrogen water tank 41 provided in the bubble generator 40.

  In the hydrogen water tank 41, hydrogen water mixed with the hydrogen gas generated by the hydrogen gas generator 1 and dissolved in the hydrogen gas is stored. The hydrogen water stored in the hydrogen water tank 41 is also supplied to the solution tank 45 through the communication pipe 46, and a surfactant is added to form a hydrogen bubble 61 that is a bubble of hydrogen water containing hydrogen gas as a film. Store the solution to produce.

  The spray nozzle 42 is inserted into the hydrogen water tank 41 and sprayed into the bathroom 60 as hydrogen water mist 62 by being pressurized with air. The spray nozzle 42 is provided with a minute hole at the tip, and is installed in the center in the height direction toward the interior of the bathroom 60.

  The bubble generation nozzle 53 is inserted into the solution tank 45, and hydrogen gas is directly supplied to the bubble generation nozzle 53 from the hydrogen gas generator 1 through the hydrogen gas supply pipe 56. Then, a hydrogen bubble 61 containing hydrogen gas is ejected into the bathroom 60. The bubble generation nozzle 53 is installed slightly below the spray nozzle 42 in the height direction toward the interior of the bathroom 60.

  43 is a combustible gas detector that detects the hydrogen gas concentration, and is installed in the bathroom 60. Since the hydrogen gas is a combustible gas, the safety of the hydrogen gas concentration in the bathroom 60 and the hydrogen gas concentration of the mist is confirmed, and if the concentration increases, the hydrogen gas from the hydrogen gas generator 1 Stop supplying.

  Since the bubble generator 40 of the first embodiment is separated from the hydrogen water tank 41 that generates the hydrogen water mist 62, not only the mist sauna using the hydrogen water but also the normal hot water using the existing hot water is used. If the mist sauna device is retrofitted to the hydrogen water supply pipes 51 and 52, the bubble sauna device can be easily configured. On the other hand, since the bubble generator 40 of Embodiment 2 shares the hydrogen water tank 41 in the production | generation of the hydrogen water mist 62 and the hydrogen bubble 61, it is small and becomes easy to carry. In any case, even if the mist sauna of the existing store is remodeled, there is no problem with the location of the additional equipment.

  Generally, it is said that blood flow is improved by taking molecular hydrogen gas into the body. Therefore, when hydrogen bubbles 61 containing hydrogen gas are jetted into the sauna, in the case of a simple mist sauna, after exiting the sauna, the difference in temperature drop on the body surface is photographed and compared, As a result, it is more difficult to lower the body surface temperature. Further, the superiority of the hydrogen bubble 61 can be evaluated by confirming the difference due to the observation of the venous blood flow.

  Regarding safety, since the explosion limit concentration of the hydrogen gas ratio between hydrogen gas and air is determined, it is confirmed by the combustible gas detector 43 provided in the bathroom 60, and when the hydrogen gas concentration increases, The supply of hydrogen gas from the hydrogen gas generator 1 is stopped.

  As described above, modern people who are unable to sweat and have difficulty adjusting body temperature due to the widespread use of cooling environments are always in dry air. Therefore, the body's moisture also begins to flow out and the body becomes dry. Also, if you don't sweat, your body's ability to regulate temperature will be weakened, making it difficult to produce waste products in your body. It is possible to provide a sauna that is extremely useful for such a modern person. In particular, by blowing a bubble containing hydrogen gas into the bathroom, the important function of “sweat” can be naturally incorporated into daily life, and the stress can be relaxed visually to enhance relaxation. can do.

  Since the bubbles preferably used in the present invention are small (diameter 0.2-2 mm, desirably about 0.5-1 mm), the amount of water occupying the volume increases and becomes heavy and difficult to float. It becomes easy to float and it becomes possible to float in the bathroom 60 for a long time.

  Moreover, it turned out that the hydrogen bubble formed by this invention is electrically charged. Therefore, it has been found that the hydrogen bubble 61 can be moved by controlling the electric field by providing an electrode in the bathroom 60 and applying a voltage to generate electrolysis.

For example, a plurality of wide and long electrodes insulated on the wall of a bathroom are provided, and an electric field is generated by applying a voltage to move the charged hydrogen bubble 61 in the electric field. Since the movement can be controlled by controlling the voltage, the sauna user can enjoy visually by the controlled movement of the hydrogen bubble 61. In particular, it is possible to provide entertainment to the user by simultaneously controlling the color and intensity of light applied to the hydrogen bubble 61 and playing music.
In the present invention, hydrogen is preferable as the gas to be included in the bubble, but other gases that are harmless to the body, such as inert gas (helium, neon, argon, krypton, xenon, radon), nitrogen, Etc. may be selected. In that case, those gas generators and those gas storage tanks can be used as gas supply means instead of the hydrogen gas generator.
