Description

  The present invention relates to a method in which hydrogen gas generated in water is retained on the surface of the water and dissolved in water, and a hydrogen gas holder for the method, and more particularly, a method for dissolving hydrogen gas in water in a bathtub and the method therefor The present invention relates to a hydrogen gas holder.

  In recent years, beverages such as water and tea filled with hydrogen (hydrogen gas) have been sold. This is aimed at reducing the active oxygen present in the human body by ingesting hydrogen. On the other hand, proposals have been made to dissolve the hydrogen in the water of the bathtub to obtain the skin-beautifying effect of the bather by the antioxidant action of hydrogen, or to obtain the effect of preventing the bathtub from being slimmed. And the apparatus for dissolving hydrogen gas in the bathtub for this is also proposed.

  For example, Patent Document 1 discloses a method of dissolving hydrogen in water in a bathtub using a hydrogen water generator that can be easily used at home. Such a device includes a container body formed of a metal material having a partitioned room and having a large number of through holes, a lid fitted to the container body, magnesium, obsidian, tourmaline, antibacterial sand, weathered coral, etc. This is a simple structure including a hydrogen water generator that fills a non-woven bag with particles such as a granular material and is stored in the chamber of the container body, and is suitable as a hydrogen water generator for a bathtub.

  On the other hand, Patent Document 2 discloses a method for dissolving hydrogen by a hydrogen water production apparatus that attempts to increase the antioxidant effect by increasing the hydrogen concentration. Hydrogen is obtained from a hydrogen cylinder or hydrogen supply means by electrolysis, and this and water taken out from the bathtub are mixed in a gas-liquid mixing tank to dissolve hydrogen, and returned to the bathtub to obtain a high hydrogen concentration. In particular, by dissolving nitrogen together in a gas-liquid mixing tank, it is said that the dissolved oxygen in water can be reduced and the antioxidant action can be enhanced.

  Patent Document 3 also discloses a method of obtaining hydrogen water having a high reducibility, that is, a high hydrogen concentration, in a method of dissolving hydrogen in water for a bathtub. That is, hydrogen is supplied from a gas supply unit comprising a hydrogen gas cylinder to an aeration unit arranged in the bathtub, and hydrogen is released as fine bubbles in water, which is dissolved in bath water to form hydrogen water. Moreover, the bathroom provided with the bathtub is provided with a hydrogen sensor and a ventilator, and the ventilator is controlled by the concentration of hydrogen released from the bath water in the air.

  Hereinafter, a hydrogen gas holding method and a hydrogen gas holder as one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

  As shown in FIG. 1, a sheet 1 used in the hydrogen gas holding method according to the present invention includes a sheet body 2 made of resin, for example, having a substantially rectangular outer shape, and a float 3 continuous along the periphery thereof. Yes. Referring particularly to FIG. 1 (b), the float 3 is a substantially cylindrical floating bag extending along the periphery of the sheet body 2, and the sheet 1 protrudes at least partially on one main surface side of the sheet 1. It is attached to the body body 2. The float 3 is preferably provided with an air valve (not shown) so that air can be taken in and out. According to this, the sheet 1 is easily folded by removing air from the float 3 except during use.

  As shown in FIG. 2, when the sheet 1 is used, the hydrogen gas generator 20 is submerged in the lower part of the bathtub 10 in which the water 12 is stored, and air is put on it to float the sheet 1 with the float 3 inflated. . Of course, it is preferable to float the sheet 1 while removing air between the sheet 1 and the water surface so that air does not collect in the lower part of the sheet 1. Moreover, it is preferable to orient the float 3 so as to protrude above the sheet body 2 with respect to the vertical direction of the sheet 1. Here, by making the float 3 into a substantially cylindrical floating bag shape extending along the periphery of the sheet body 2, the sheet 1 can be easily floated on the water surface, and the rectangle which is the outer shape can be easily maintained. That is, the float 3 is a rib that extends along the peripheral edge of the sheet 1 and has a specific gravity smaller than that of water. Further, by providing such a rib 3 by the float 3, the flexibility of the central portion can be made higher than the flexibility of the peripheral portion of the sheet 1 having the rib.

  As shown in FIG. 3, the hydrogen gas 21 generated from the hydrogen gas generator 20 floats while being partially dissolved in the water 12 and desorbs upward from the water surface. At this time, the hydrogen gas 21 is pressed down by the sheet 1 and held on the water surface. In particular, the sheet 1 is made to have higher flexibility at the center than at the periphery by ribs made of the float 3. That is, the center portion is easily bent upward. Accordingly, the hydrogen gas is moved to the center portion of the sheet 1 to facilitate the formation of the gas reservoir 22, and the hydrogen gas escaping from the periphery of the sheet 1 can be reduced to stably hold the hydrogen gas. In this way, the hydrogen gas 21 can stay on the surface of the water for a long time, and desorption of the hydrogen gas from the water 12 can be suppressed, and the pressure of the gas reservoir 22 is increased by the weight of the lifted sheet 1, Dissolution in water 12 can be promoted.

  Further, since the float 3 protrudes from the upper surface of the sheet 1, it is easy to remove air from the lower part of the sheet 1 when the sheet 1 is floated on the water surface, and the hydrogen partial pressure can be increased by reducing the air mixed in the gas reservoir 22. . And the peripheral part of the sheet | seat body main body 2 will be maintained in a lower position, and the weight of the sheet | seat 1 can be loaded more to the gas reservoir 22, and the pressure of the gas reservoir 22 can be raised. Further, by providing the float 3, even if a sheet body body 2 having a greater weight, for example, a material having a large specific gravity or a sheet body having a large thickness is used, the sheet 1 can be floated on the water surface. Also, the pressure of the gas reservoir 22 can be increased.

  Here, the material of the sheet 1 is one that can prevent leakage of hydrogen gas, and preferably a synthetic resin film composed of a synthetic resin is used, but a synthetic resin sheet such as a vinyl chloride resin sheet can also be used. . Examples of the material of the synthetic resin film include polyethylene, polyamide, polyethylene terephthalate, polypropylene, polyvinyl alcohol, and ethylene vinyl alcohol copolymer. The synthetic resin film may be formed with a vapor deposition layer made of metal or inorganic oxide, or may be laminated with a metal foil. A preferable example of the synthetic resin film includes a heat seal layer made of a heat-sealable material and a gas barrier layer made of a hydrogen gas-impermeable material, and at least the inner surface side is made of a heat seal layer. A laminated film is mentioned. Examples of the material of the heat seal layer include polyethylene and polypropylene. The material of the gas barrier layer is a synthetic resin film that is impermeable to hydrogen gas such as polyamide, ethylene-vinyl alcohol copolymer resin, polyethylene terephthalate, a metal or inorganic oxide deposition layer formed on the synthetic resin film, or a synthetic layer. Examples thereof include metal foils laminated on a resin film, and polyamide films, ethylene-vinyl alcohol copolymer resin films, and metal deposited films thereof are particularly preferably employed. Moreover, you may perform the process which improves hydrogen gas impermeability further, such as vapor-depositing a silica and an alumina on the surface of the sheet | seat 1. FIG.

  Moreover, as the hydrogen gas production | generation tool 20, the well-known thing which accommodated in the container magnesium, calcium, obsidian, tourmaline, antibacterial sand, weathered coral, etc. which react with water and generate | occur | produce hydrogen gas, for example can be used.

  As described above, according to the present embodiment, hydrogen gas can be stably held at the lower portion of the sheet 1 on the water surface of the bathtub 10, and dissolution of hydrogen gas in water can be promoted. That is, desorption of hydrogen gas from water can be suppressed and hydrogen gas can be used efficiently.

  As mentioned above, although the Example by this invention and the modification based on this were demonstrated, this invention is not necessarily limited to this, A person skilled in the art will deviate from the main point of this invention, or the attached claim. Various alternative embodiments and modifications could be found without doing so.
