Description

  The present invention relates to a hydrogen generator for bathing, and more particularly to a hydrogen generator for bathing that generates hydrogen in hot water in a bath for the purpose of improving the bathing effect.

  Diseases such as allergies and cancer and aging are thought to be mainly caused by active oxygen. Incorporating hydrogen into the body has been proposed as a method for protecting the human body from active oxygen that can adversely affect the body. This is because, for example, vitamin E, known as an antioxidant, removes superoxide, which is a good active oxygen, while hydrogen selectively removes only the hydroxyl radical, which is a vicious active oxygen. This is because it can be done. In addition, hydrogen is the only antioxidant that can dissolve in both water and oil, so it can reach intracellular mitochondria and nuclei. Thereby, hydrogen can also have an effect that DNA and the like can be repaired. Examples of methods for taking hydrogen into the body include drinking so-called hydrogen water and taking a bath in a bathtub (hereinafter simply referred to as “hydrogen bath”) containing hot water containing hydrogen. In particular, bathing in a hydrogen bath has good absorption efficiency because hydrogen can be taken directly from the skin. Furthermore, suppression of skin troubles and cosmetic effects can be expected. As a hydrogen generator for bathing for generating hydrogen in hot water in a bathtub, for example, a hydrogen gas bubble bath apparatus of Patent Document 1, a water reforming apparatus of Patent Document 2, and a hydrogen water for bath of Patent Document 3 There are generators.

  The hydrogen gas bubble tub device of Patent Document 1 includes a hydrogen gas supply means for supplying hydrogen gas into the bath water in the bathtub, a large first hydrogen gas container filled with hydrogen gas, and the interior of the bathtub at a time. A small second hydrogen gas container filled with hydrogen gas in an amount to be supplied into the bath water, and a first hydrogen gas supply pipe for supplying hydrogen gas from the first hydrogen gas container to the second hydrogen gas container A first hydrogen gas supply pipe provided with a solenoid valve in the pipe, and a second hydrogen gas supply pipe for supplying hydrogen gas from the second hydrogen gas container to the hydrogen gas supply means. And a second hydrogen gas supply pipe provided with a solenoid valve in the path.

The water reforming apparatus of Patent Document 2 includes an electrolytic cell into which tap water is introduced, a first electrode, a second electrode, and a first electrode, a second electrode, which are disposed to face each other in the electrolytic cell. It is comprised from the voltage application circuit which is a voltage application means which applies a DC voltage between the some intermediate electrode arrange | positioned and the 1st, 2nd electrode. When the voltage V ₀ is applied between the first electrodes, Mg ²⁺ ions are dissolved from the intermediate electrode on the high potential side made of a magnesium material, and the tap water in the electrolytic cell is modified to be alkaline. Further, in the vicinity of one of the low potential side intermediate electrode and the second electrode, a reaction occurs in which hydrogen ions 2H ⁺ receive electrons and become hydrogen gas H ₂ . This hydrogen gas H ₂ is dissolved in the tap water until it becomes supersaturated.

  The hydrogen water generator for baths of Patent Document 3 includes a substantially rectangular stainless steel container body, a lid fitted to the container body, and a hydrogen water generator housed in a chamber of the container body. Configured as the subject. The container main body is partitioned through a partition plate, and a plurality of rooms are formed. A through hole is opened in the partition plate. The lid has a large number of through holes on the upper surface. The hydrogen water generator is composed of a non-woven bag and particles mixed with at least one or several kinds of granular materials such as magnesium, obsidian, tourmaline, antibacterial sand, and weathered coral. Therefore, water is converted into hydrogen water upon contact with the particles of the hydrogen water generator.

The magnesium fixing member 90 is preferably formed of rubber or the like having elasticity, and the diameter of the through hole 92 is preferably slightly smaller than that of the shaft member 50 of the housing 20.

(Usage procedure etc.)
The bathing hydrogen generator 10 according to this embodiment can be used only by being placed on the bottom of the bathtub. In addition, the hydrogen generator 10 for bathing may be placed on the bottom of the bathtub after hot water is put into the bathtub or may be placed in front of it. The hydrogen generator 10 for bathing generates hydrogen inside the housing 20 when the magnesium plates 80a to 80c chemically react with water molecules in the bath. Hydrogen generated inside the housing 20 is released to the outside through a plurality of holes 64 formed in the lid 60 and reaches hot water in the bathtub. The chemical formula showing the chemical reaction between the magnesium plates 80a to 80c and the water molecules in the bath is as follows.

  In addition, the hydrogen generator 10 for bathing may further include a citric acid solution for promoting chemical reaction between the magnesium plates 80a to 80c and water molecules by being injected into the housing 20.

(Replacement procedure of magnesium plates 80a to 80c)
Next, an example of a procedure for exchanging the magnesium plates 80a to 80c worn out by chemical reaction with water molecules in the bathtub will be described.

  First, hot water is drained from the bathtub.

  Next, the lid 60 is picked up by the knob 70 and lifted upward to reveal the opening formed in the top surface of the housing 20.

  Further, the magnesium fixing member 90 that is in a state that can be visually recognized substantially in the center in plan view is removed from the shaft member 50.

  Further, the worn magnesium plate 80 c is lifted upward, removed from the shaft member 50, and removed to the outside of the housing 20. Similarly, the interposed member 84c, the worn-down magnesium plate 80b, the interposed member 84b, and the worn-down magnesium plate 84a are extracted from the shaft member 50 in this order and taken out to the outside of the housing 20.

  Then, the new magnesium plate 80 a is positioned inside the housing 20 by inserting the through hole 82 into the shaft member 50. Similarly, the interposed member 84b, the new magnesium plate 80b, the interposed member 84c, and the new magnesium plate 84c are inserted into the shaft member 50 in this order to be positioned inside the housing 20.

  Next, the magnesium plates 80 a to 80 c are fixed inside the housing 20 by attaching the magnesium fixing member 90 to the tip portion of the shaft member 50. The magnesium fixing member 90 is formed of rubber or the like having elastic force, and the diameter of the through hole 92 is slightly smaller than that of the shaft member 50 of the housing 20. The shaft member 50 can be press-fitted and attached. Thereby, the magnesium fixing member 90 can fix the magnesium plates 80a to 80c more reliably. As described above, the magnesium plates 80 a to 80 c can be attached to the base body 30.

  Finally, the lid 60 covers the top surface of the housing 20. Specifically, the lid 60 is inserted into the housing 20 from the side of the lid bottom plate 62 by picking the knob 70. Then, the end edge curved portion 68 of the lid 60 is positioned by being placed on the upper end edge of the base side plate 40. In this way, the top surface of the housing 20 can be covered.

  As described above, it is possible to replace the magnesium plates 80a to 80c that have been worn down by chemically reacting with water molecules in the bathtub.

  In addition, an oxide film (darkening) may be formed on the surfaces of the magnesium plates 80a to 80c by chemically reacting with water molecules in the bathtub. Since the oxide film prevents the magnesium plates 80a to 80c and water molecules from chemically reacting with each other, the amount of hydrogen generated is reduced. Therefore, it is preferable that the oxide film be periodically removed before replacing the magnesium plates 80a to 80c that have been worn out as described above. It is preferable that the bathing hydrogen generator 10 includes a citric acid solution for removing the oxide film.

(effect)
The hydrogen generator 10 for bathing according to this embodiment includes a base body 30 that comes into contact with a placement surface and magnesium plates 80a to 80c attached to the base body 30, and the magnesium plates 80a to 80c are included in hot water. It generates hydrogen by chemically reacting with water molecules. Since the bathing hydrogen generator 10 has a simple structure that does not use electricity, there is no risk of failure. Moreover, since it only needs to mount in the bottom of a bathtub, a use procedure is simple. Furthermore, no cost is required for production or installation, the running cost can be kept low, and a sufficient amount of hydrogen can be generated. Since it is as above, the hydrogen generator 10 for bathing according to this embodiment has a simple structure, there is no risk of failure, can reduce costs in all aspects, and the usage procedure is simple. In addition, a sufficient amount of hydrogen can be generated.

  Further, in the hydrogen generator 10 for bathing according to this embodiment, the magnesium plates 80 a to 80 c are positioned with respect to the base body 30 by passing the shaft member 50 through the through holes 82. Thereby, magnesium plate 80a-80c can be accommodated in the base body 30 in the stable state. Further, the magnesium plates 80 a to 80 c can be attached to or detached from the base body 30 by being inserted into and removed from the shaft member 50. Therefore, the hydrogen generator 10 for bathing according to this embodiment can easily perform assembly work at the time of introduction, replacement work of the magnesium plates 80a to 80c that have been worn down, and the like.

  Furthermore, the hydrogen generator 10 for bathing according to this embodiment is projected from the top surface of the base body 30 and extends in the height direction. Thereby, since the hydrogen generator 10 for bathing concerning this embodiment is attached to the base body 30 so that each of the magnesium plates 80a to 80c extends in the horizontal direction, it is mounted in a stable state on the bottom of the bathtub. Can be placed. Furthermore, since the through-hole 82 drilled in each of the magnesium plates 80a to 80c and the shaft member 50 are visible from above, it is easy to insert and remove the magnesium plates 80a to 80c with respect to the shaft member 50. . Thereby, the hydrogen generator 10 for bathing according to this embodiment can more easily perform assembly work at the time of introduction and replacement work of the magnesium plates 80a to 80c that have been worn down.

  And the hydrogen generator 10 for bathing concerning this embodiment is provided with the three magnesium plates 80a-80c, and these magnesium plates 80a-80c let the shaft member 50 pass through the through-hole 82, and intervene. By interposing the members 84a to 84c, they are stacked apart in the height direction. Thereby, since the hydrogen generator 10 for bathing according to this embodiment can secure a sufficiently large area where each of the magnesium plates 80a to 80c is in contact with water molecules, a larger amount of hydrogen is generated. It becomes possible.

  Further, the hydrogen generator 10 for bathing according to this embodiment further includes a base side plate 40 that rises from the edge of the base body 30, and the magnesium plates 80 a to 80 c include a housing that includes the base body 30 and the base side plate 40. 20 is housed inside. Thereby, the hydrogen generator 10 for bathing according to this embodiment can obtain good durability and aesthetics.

  Furthermore, the bathing hydrogen generator 10 according to this embodiment further includes a lid 60 for covering the housing 20, and hydrogen generated inside the housing 20 is transferred to the lid 60. A plurality of holes 64 are formed for discharge. Thereby, hydrogen can be released to the outside while keeping the inside of the housing 20 invisible. Therefore, the bathing hydrogen generator 10 according to this embodiment can obtain good durability and aesthetics. The effect of good aesthetics is particularly effective when each of the magnesium plates 80a to 80c is worn away by a chemical reaction.

  And the hydrogen generator 10 for bathing which concerns on this embodiment is further equipped with the citric acid solution for accelerating | stimulating that the magnesium plates 80a-80c and a water molecule react chemically. The citric acid solution can remove the oxide film formed on the surface of each of the magnesium plates 80a to 80c by chemically reacting with water molecules, whereby the above-described chemical reaction can be promoted. As a result, the hydrogen generator 10 for bathing according to this embodiment can increase the amount of hydrogen generated in the hot water in the bathtub.

  In the hydrogen generating apparatus 10 for bathing according to this embodiment, one shaft member 50 protrudes from a substantially central portion of the base body 30 in plan view, and each of the magnesium plates 80a to 80c includes the shaft member. A through hole 82 corresponding to 50 is formed. Thereby, since the gravity center of magnesium plate 80a-80c comes to be located in planar view substantially center part, the hydrogen generator 10 for bathing attaches magnesium plate 80a-80c to the base body 30 in the stable state. It becomes possible.

  In addition, the bathing hydrogen generator 10 according to this embodiment has a substantially circular outer shape when the housing 20 is viewed in plan because the base body 30 is substantially circular in plan view. This reduces the risk of injury when a foot or the like is struck against the hydrogen generator 10 for bathing. In particular, it is difficult for the hydrogen generator 10 for bathing to have a sense of distance due to light refraction in a bathtub in which hot and cold water is placed. Therefore, it is reasonable to make the shape as described above.

  In the hydrogen generator 10 for bathing according to this embodiment, since the interposition members 84a to 84c are positioned by the shaft member 50, the magnesium plate 80a even if the magnesium plates 80a to 80c are worn out. The state of ˜80c separated from each other is maintained. Thereby, each of the magnesium plates 80a to 80c can be in contact with water molecules in the bathtub over the entire surface even when the magnesium plates 80a to 80c are worn out. As a result, the hydrogen generator 10 for bathing according to this embodiment can generate a sufficient amount of hydrogen in a constant manner over a long period of time.

It is almost in contact.

(Magnesium plates 80a-80w)
The magnesium plates 80a to 80w are accommodated in the housing 20 in a state where they are stacked in the height direction. The magnesium plate 80a is located closest to the base body 30, the next is the magnesium plate 80b, and the next is the magnesium plate 80c. Similarly, the magnesium plate 80w is stacked in alphabetical order and is located farthest from the base body 30.

The magnesium fixing member 90 is preferably formed of rubber or the like having elasticity, and the diameter of the through hole 92 is preferably slightly smaller than that of the shaft member 50 of the housing 20.

(Usage procedure etc.)
The hydrogen generator 10 for bathing according to this embodiment can be used only by being placed in a relatively large bathtub such as a public bath. Since the procedure for using the bathing hydrogen generator 10 according to this embodiment is the same as that of the bathing hydrogen generator 10 according to the first embodiment, the description thereof will not be repeated here. In addition, the hydrogen generator 10 for bathing according to this embodiment injects a citric acid solution for accelerating the chemical reaction between the magnesium plates 80a to 80w and water molecules by being injected into the housing 20. Further, it may be provided.

(Replacement procedure of magnesium plates 80a-80w)
Next, an example of a procedure for exchanging the magnesium plates 80a to 80w worn out by chemical reaction with water molecules in the bathtub will be described.

  First, hot water is drained from the bathtub.

  Next, the lid 60 is removed, and an opening formed in the top surface of the housing 20 is exposed. Specifically, first, the female screw formed on the shaft fixing member 200 is grasped and rotated counterclockwise (counterclockwise) in the plan view by gripping the shaft fixing member 200 located at a substantially central portion in the plan view of the lid body 60. The screwing between the portion 212 and the male screw portion 152 formed at the tip of the shaft member 50 is removed, and the shaft fixing member 200 is removed. And the opening formed in the top | upper surface of the housing 20 is revealed by lifting and removing the cover body 60 substantially upward.

  Further, the magnesium fixing member 90 that is in a state that can be visually recognized substantially in the center in plan view is removed from the shaft member 50.

  Further, the worn magnesium plate 80 w is lifted upward, removed from the shaft member 50, and removed to the outside of the housing 20. Similarly, the intermediate member 84w, the worn magnesium plate 80v, the interposed member 84v, the worn magnesium plate 80u, and the interposed member 84u are extracted from the shaft member 50 up to the magnesium plate 80a in the reverse order of the alphabet. Then, it is taken out of the housing 20.

  Then, the new magnesium plate 80 a is positioned inside the housing 20 by inserting the through hole 82 into the shaft member 50. Similarly, the magnesium plate 80w is inserted into the shaft member 50 in alphabetical order like the interposed member 84b, the new magnesium plate 80b, the interposed member 84c, and the new magnesium plate 80c, and is positioned inside the housing 20. .

  Next, the magnesium plates 80 a to 80 w are fixed inside the housing 20 by attaching the magnesium fixing member 90 to the tip portion of the shaft member 50. The magnesium fixing member 90 is formed of rubber or the like having elastic force, and the diameter of the through hole 92 is slightly smaller than that of the shaft member 50 of the housing 20. The shaft member 50 can be press-fitted and attached. Thereby, the magnesium fixing member 90 can fix the magnesium plates 80a to 80w more reliably. As described above, the magnesium plates 80 a to 80 w can be attached to the base body 30.

  Further, the lid 60 covers the top surface of the housing 20. Specifically, the top edge of the housing 20 is covered by placing the radial edge of the lid top plate 63 on the upper edge of the base side plate 40.

  Finally, the shaft member 50 is fixed by the shaft fixing member 200. Specifically, the fitting portion 210 of the shaft fixing member 200 is drilled in the substantially central portion of the lid top plate 63 in plan view while holding the grip portion 220 of the shaft fixing member 200 and rotating it clockwise (clockwise) in plan view. It fits into the provided through hole 180. As a result, the male screw portion 152 formed at the tip portion of the shaft member 50 is screwed into the female screw portion 212 formed in the shaft fixing member 200. In this way, the shaft member 50 is fixed by the shaft fixing member 200. At this time, the fitting portion 210 is fitted into the through hole 180 formed in the substantially central portion of the lid 60 in plan view, and the grip portion 220 is provided on the edge of the through hole 180 and the top surface side of the vicinity thereof. The edge of the bottom surface and the vicinity thereof are in contact with or substantially in contact with each other.

  As described above, it is possible to replace the magnesium plates 80a to 80w that have been worn down by chemically reacting with water molecules in the bathtub.

  In addition, an oxide film (darkening) may be formed on the surfaces of the magnesium plates 80a to 80w by chemically reacting with water molecules in the bathtub. Since the oxide film prevents the magnesium plates 80a to 80w and water molecules from chemically reacting with each other, the amount of hydrogen generated is reduced. Therefore, it is preferable that the oxide film is periodically removed before the magnesium plates 80a to 80w that have been worn out as described above are replaced. It is preferable that the bathing hydrogen generator 10 includes a citric acid solution for removing the oxide film.

(effect)
The hydrogen generator 10 for bathing according to this embodiment includes a base body 30 that comes into contact with the mounting surface, and magnesium plates 80a to 80w attached to the base body 30, and the magnesium plates 80a to 80w are included in hot water. It generates hydrogen by chemically reacting with water molecules. Since the bathing hydrogen generator 10 has a simple structure that does not use electricity, there is no risk of failure. Moreover, since it only needs to mount in the bottom of a bathtub, a use procedure is simple. Furthermore, no cost is required for production or installation, the running cost can be kept low, and a sufficient amount of hydrogen can be generated. Since it is as above, the hydrogen generator 10 for bathing according to this embodiment has a simple structure, there is no risk of failure, can reduce costs in all aspects, and the usage procedure is simple. In addition, a sufficient amount of hydrogen can be generated.

  In the hydrogen generator 10 for bathing according to this embodiment, a total of 23 magnesium plates 80 a to 80 w are passed through the shaft member 50 of the housing 20. That is, since the bathing hydrogen generator 10 according to this embodiment includes more magnesium plates 80 than the first embodiment described above, a larger amount of hydrogen can be generated. Therefore, this hydrogen generator 10 for bathing can be effectively used particularly in a relatively large bathtub such as a public bath.

  The lid 60 according to this embodiment further includes a shaft fixing member 200 for fixing the shaft member 50. Thereby, the shaft member 50 is fixed to the lid 60. As a result, the hydrogen generator 10 for bathing according to this embodiment can accommodate the magnesium plates 80a to 80w inside the housing 20 in a more stable state.

  Further, a male screw part 152 is formed at the tip of the shaft member 50 according to this embodiment, and a female screw part 212 for screwing with the male screw part 152 is formed on the shaft fixing member 200. . As a result, the hydrogen generator 10 for bathing according to this embodiment can store the magnesium plates 80a to 80w in the housing 20 with a simple structure and in a more stable state.

  And unlike the case of the second embodiment described above, the hydrogen generator 10 for bathing according to this embodiment has a plurality of holes for releasing the hydrogen generated inside the housing 20 to the outside. 64 is drilled only in the lid 60 and not in the base side plate 40. Thereby, the oxide film formed on the surface of the magnesium plates 80a to 80w can be removed by chemically reacting with the water molecules in the bath using the citric acid solution. This is because the citric acid solution does not leak out of the housing 20 because the plurality of holes 64 are not formed in the base side plate 40 as described above. In the hydrogen generator 10 for bathing, the oxide film formed on the surfaces of the magnesium plates 80a to 80w is removed using a citric acid solution, so that the magnesium plates 80a to 80w and the water molecules in the bathtub react chemically. The amount of hydrogen generated can be increased.

  In this embodiment, in the state where the shaft fixing member 200 is attached to the shaft member 50, the edge of the bottom surface of the grip portion 220 of the shaft fixing member 200 and the vicinity thereof are formed in the lid top plate 63. The end of the through-hole 180 and the top surface side of the vicinity thereof are in contact with or almost in contact with each other. With such a structure, the shaft fixing member 200 prevents the lid body 60 from moving in the height direction. That is, the shaft fixing member 200 fixes the shaft member 50 and also fixes the lid 60. Therefore, it is possible to prevent the lid body 60 from being accidentally detached from the housing 20. As a result, the hydrogen generator 10 for bathing according to this embodiment has improved safety and aesthetics, and can be suitably used in a relatively large bath such as a public bath.

4). Modified Example The case where the hydrogen generator 10 for bathing according to the first embodiment, the second embodiment, and the third embodiment described above includes the shaft member 50 extending in the height direction has been described. The magnesium plates 80a to 80c according to the first embodiment, the magnesium plates 80a to 80e according to the second embodiment, and the magnesium plates 80a to 80w according to the third embodiment are respectively By passing the shaft member 50 through the through-hole 82, the shaft member 50 was stacked in the height direction while being placed horizontally, and was accommodated in the housing 20. However, the present invention is not limited to this, and the hydrogen generator 10 for bathing may include a shaft member 50 extending in the horizontal direction, for example. In such a case, the magnesium plates 80a to 80c according to the first embodiment, the magnesium plates 80a to 80e according to the second embodiment, and the magnesium plates 80a to 80w according to the third embodiment. When the shaft member 50 is passed through each through hole 82, the shaft member 50 is arranged in the horizontal direction in a vertically placed state and is accommodated in the housing 20.

  In the first embodiment and the third embodiment described above, the plurality of holes 64 formed in the lid 60 for releasing the hydrogen generated inside the housing 20 to the outside is a flat surface. The case has been described in which the shape is substantially circular and is arranged so as to spread radially from the center of the lid bottom plate 62. However, the present invention is not limited to this case, and the plurality of holes 64 may have other shapes such as a substantially quadrangular shape in a plan view, or the lid bottom plate 62 according to the first embodiment and the third shape. The lid top plate 63 according to the embodiment may be uniformly arranged as a whole. In consideration of the case where the citric acid solution is injected into the housing 20, it is preferable not to drill the plurality of holes 64 in the base body 30 or the base side plate 40.

  Furthermore, in the above-described second embodiment, the plurality of holes 64 are substantially circular in plan view, and are arranged radially from each of the positions corresponding to the six shaft members 50 on the lid top plate 63, In addition, the case where the lid side plate 66 is uniformly arranged as a whole has been described. However, the present invention is not limited to this case, and the plurality of holes 64 may have other shapes such as a substantially square shape in a plan view, and the lid top plate 63 as a whole is similar to the lid side plate 66. It may be arranged uniformly. In addition, the plurality of holes 64 are formed in, for example, only the lid top plate 63 and may not be formed in the lid side plate 66, or the lid top plate 63, the lid side plate 66, and the base body 30. All may be drilled.

  As described above, the hydrogen generator 10 for bathing appropriately adjusts the shape and arrangement of the plurality of holes 64 for releasing the hydrogen generated inside the housing 20 to the outside, so that a desired foaming by hydrogen is generated. Can produce.

  In the first embodiment described above, the case where the three magnesium plates 80 a to 80 c are attached to one shaft member 50 has been described. In the above-described third embodiment, the case where 23 magnesium plates 80a to 80w are attached to one shaft member 50 has been described. However, the present invention is not limited to this case, and only one magnesium plate 80 may be attached to the shaft member 50. As a result, the manufacturing cost can be kept low, and the replacement work of the worn magnesium plate 80 can be easily performed.
