Description

  The present invention relates to a method for continuously producing hydrogen water used for drinking water, bath water, and the like, a production apparatus therefor, and a bath apparatus and a bathroom apparatus employing the hydrogen water production means.

  So-called hydrogen water in which hydrogen is mixed into water and dissolved in water in the form of fine bubbles becomes a countermeasure against active oxygen (antioxidant) in the human body by drinking, and it is used as washing water and bathing water because of its reducibility. Yes.

  Patent Document 1 (Japanese Patent Application Laid-Open No. 2000-354696) discloses a hydrogen water production means comprising a water inlet side pipe, a hydrogen saturation tank, and a water discharge side discharge pipe connected to a water flow pipe. In the above, hydrogen agitation is performed rapidly with a stirrer (powered motor drive) while receiving supply of hydrogen gas, and hydrogen saturated water is obtained using hydrogen gas as fine bubbles.

  Patent Document 2 (Japanese Patent Laid-Open No. 2004-66071) discloses an example of use as bathing water, and hydrogen water is produced by dissolving hydrogen in a gas-liquid mixing tank under a predetermined pressure. Dissolved hydrogen is used, and the hydrogen-mixed water is irradiated with ultraviolet rays with an ultraviolet irradiation tube into the bath to obtain water containing active hydrogen, and active hydrogen water containing fine bubbles of active hydrogen is supplied from the pressure release portion. .

JP 2000-354696 A. JP 2004-66071 A.

  Hydrogen water exists as so-called dissolved hydrogen in which fine bubbles are dissolved in water, and even if it is effectively stirred, it becomes saturated at about 1.5 ppm, and the saturated state of dissolved hydrogen is the water temperature and fine bubbles. It varies depending on the production means, and is not constant. If it does so, in the hydrogenous water manufacturing apparatus of patent document 1, in order for the hydrogen water produced to be saturated hydrogen water, naturally it becomes hydrogen mixed water containing excess hydrogen.

  Therefore, the hydrogen water produced by the production apparatus has surplus hydrogen other than dissolved hydrogen in the form of bubbles, and it was tried to provide hydrogen water as potable water by bottling (PET bottle packaging or other packaging). In such a case, the gas stays in the bottle as high-pressure hydrogen gas, and the hydrogen gas is ejected when the bottle is opened, which is very dangerous when there is fire in the vicinity.

  Similarly, as disclosed in Patent Document 2, when hydrogen water is used as bathing water, hydrogen gas is released from the bath water in the bathtub, and is formed in a closed room particularly from the viewpoint of thermal efficiency. In the bathroom, the released hydrogen gas stays in the bathroom, and the presence of the bath water heating device leads to a very dangerous state.

  Therefore, the present invention proposes means for continuously producing saturated hydrogen water that does not contain surplus hydrogen gas, and a novel bathing apparatus and bathroom apparatus that employs the means.

  In the method for continuously producing hydrogen water according to the present invention (Claim 1), hydrogen gas and water are mixed by a gas-liquid mixing pump and discharged at a predetermined pressure, and the hydrogen-mixed water is stirred in the middle of the flow path to generate bubbles. After passing through the agitating part to be refined, the flow rate is slowed down and the remaining hydrogen is released to discharge surplus hydrogen, and saturated hydrogen water is continuously produced.

  Further, a continuous hydrogen water production apparatus according to the present invention (Claim 3) includes a water supply unit, a hydrogen supply unit, and a gas-liquid mixture that receives supply of water and hydrogen from each of the supply units and discharges hydrogen-mixed water. A pump, a stirring unit in which the hydrogen-mixed water discharged from the gas-liquid mixing pump is stirred, and a discharge stabilization tank in which the hydrogen-mixed water from the stirring unit forms a predetermined stagnation and releases hydrogen other than dissolved hydrogen It is characterized by including.

  Thus, after mixing and stirring hydrogen in the water, when the hydrogen-mixed water flow stagnates in the degassing stabilization tank, surplus mixed hydrogen is released at that time, and saturated hydrogen water in which dissolved hydrogen is saturated remains. Hydrogen water in which surplus hydrogen is significantly reduced can be continuously supplied.

  Further, the hydrogen water production apparatus according to the present invention (Claim 6) is provided with each part through which hydrogen water and hydrogen-mixed water flow (a gas-liquid mixing pump, a stirrer, and a hydrogen-mixed water production apparatus comprising a degassing stabilizing tank The flow range connecting them) is arranged in an appropriate storage chamber, the indoor chamber is provided with a discharge mechanism for indoor air, a hydrogen sensor is provided in the discharge passage of the discharge mechanism or the storage chamber, and the hydrogen supply section and the The on-off valve mechanism provided in the hydrogen gas supply path connecting the liquid mixing pumps is controlled based on the detection of the hydrogen sensor. Further, the operation of the discharge mechanism is controlled based on the detection of the hydrogen sensor (Claim 7).

  Thus, in the hydrogen water production process, when hydrogen released from the hydrogen-mixed water mixed with surplus hydrogen leaks in the production process, the leaked hydrogen stays in the storage chamber and is discharged by the discharge mechanism. Although exhausted outside the storage chamber, when the hydrogen concentration reaches a predetermined value or more, the on-off valve mechanism is operated to stop the supply of hydrogen gas, and the discharge mechanism is controlled based on the detection value of the hydrogen sensor. The leakage of hydrogen gas can be reliably detected, the leaked hydrogen is properly released to the outside air, and the concentration of the possibility of explosion is not reached so as to ensure the safety of the entire apparatus. The present invention can also be applied to the hydrogen water production part in the following bathing apparatus and bathroom apparatus.

  Further, a bathing apparatus according to the present invention (Claim 8) includes a bath water supply unit, a hydrogen supply unit, a gas-liquid mixing pump that receives supply of water and hydrogen from each of the supply units and discharges hydrogen-containing water, An agitation unit in which hydrogen-mixed water discharged from the gas-liquid mixing pump is agitated, an air-release stabilization tank in which the hydrogen-mixed water from the agitation unit forms a predetermined stagnation and releases hydrogen other than dissolved hydrogen; It is characterized by comprising a bathtub for receiving bath water from a stabilization tank.

  Thus, similar to the above hydrogen water production apparatus, it is possible to supply bath water using hydrogen water with reduced excess hydrogen mixture, and hydrogen with excellent cleaning effect and skin beautifying effect (effect due to high reduction potential). Safe bathing with water is realized.

  Furthermore, the bathroom apparatus according to the present invention (Claim 11) includes a bathroom in which a bathtub is placed, in addition to the bathing apparatus, and is provided with a predetermined exhaust ventilation mechanism in the bathroom, and an appropriate position in the bathroom or an exhaust ventilation mechanism. Either a hydrogen sensor in the bathroom is provided in the discharge channel, and a shut-off valve mechanism provided in the supply channel for supplying hot water from the discharge ventilation tank to the bathtub based on the detection value of the hydrogen sensor in the bathroom. One or both operations are controlled.

  Thus, when the bath water is supplied with hydrogen water with reduced excess hydrogen mixed in, and the surplus hydrogen is released from the bath water and the hydrogen concentration in the bathroom reaches a predetermined value or higher, the supply of the hydrogen water bath water is stopped. Or ventilating the bathroom by operating the discharge mechanism.

  Since the configuration of the present invention is as described above, it is possible to continuously produce saturated hydrogen water in which the presence of surplus hydrogen is reduced, and when using hydrogen water having a high cleaning effect as bath water, surplus Since there is little mixing of hydrogen, bathing can be performed safely, and the use of hydrogen water can be realized more safely by providing a hydrogen sensor and performing ventilation in the bathroom.

  Next, an embodiment of the present invention will be described. FIG. 1 shows an embodiment (first embodiment) of a hydrogen water production apparatus. The entire apparatus includes a water supply unit 1, a hydrogen supply unit 2, a gas-liquid mixing pump 3, a stirring unit 4, and an air discharge stabilization tank. 5 and the storage chamber 6.

  The water supply unit 1 supplies water for hydrogen mixing, and uses water corresponding to the purpose of use of the produced hydrogen water, such as using tap water directly or using pure water from a separate pure water production device. If it supplies and supplies a heating part and supplies as warm water (about 20 degreeC is a standard), the dissolved rate of hydrogen gas will increase.

  The hydrogen supply unit 2 is general because it uses a hydrogen gas cylinder, but the hydrogen gas obtained by combining a water electrolysis device may be used. Further, an open / close valve mechanism 21 is provided from the hydrogen gas cylinder (hydrogen supply unit) to the hydrogen gas supply path.

  The gas-liquid mixing pump 3 employs an existing general pump, and mixes the water A from the water supply unit 1 and the hydrogen gas B from the hydrogen supply unit (hydrogen gas cylinder) 2 with a predetermined pressure. Is discharged.

Therefore, the hydrogen sensor 61 is installed at an appropriate position in the room or in the discharge path of the discharge mechanism 62, and controls the opening / closing operation of the on-off valve mechanism 21 based on the detected value, or controls the discharge mechanism 62 as necessary. To do. Further, the discharge mechanism 62 may be in an always operating state, or may be controlled in operation based on the detection value of the hydrogen sensor 61.

  Thus, when the water A from the water supply unit 1 and the hydrogen gas B from the hydrogen supply unit (hydrogen gas cylinder) 2 are supplied to the gas-liquid mixing pump 3, and both are mixed and discharged at a predetermined pressure, C flows into the stirring unit 4 at a predetermined flow rate, and the water flow collides with the fixed stirring blades of the stirring unit 4 so that the bubbles of hydrogen gas are finely divided into a dissolved state.

  Then, when the hydrogen water D in which part of the hydrogen gas is dissolved hydrogen flows into the discharge stabilization tank 5, the hydrogen water D is in a stagnation state, and surplus hydrogen mixed in the hydrogen water D (other than dissolved hydrogen) Gas) is released from the hydrogen water D and accumulates in the upper space of the discharge stabilization tank 5, and the hydrogen gas is released from the discharge portion 51 to the outside of the discharge stabilization tank 5. Of course, the released hydrogen E may be released into the atmosphere as it is, or may be supplied again to the gas-liquid mixing pump 3 as hydrogen gas B.

  Hydrogen water F continuously discharged from the discharge passage 52 of the discharge stabilization tank 5 is hydrogen water containing a sufficient amount of dissolved hydrogen (saturated hydrogen water: content of hydrogen 0.35 to 045 ppm, oxidation-reduction potential −300 to It is about -500 mV) and contains almost no surplus hydrogen gas, and can be provided as drinking water (hydrogen water) as it is as a bottle or as cleaning water so as to use an excellent cleaning effect.

  Further, in the hydrogen water production apparatus, a place where a large amount of surplus hydrogen is mixed (the gas-liquid mixing pump 3, the agitation unit 4, the discharge stabilization tank 5, and the flow path connecting the above parts) is disposed in the storage chamber. Therefore, even if surplus hydrogen leaks from the location, the leaked hydrogen stays in the storage chamber 6 and is exhausted out of the storage chamber by the discharge mechanism 62. In particular, when the hydrogen concentration reaches a predetermined value or more as detected by the hydrogen sensor 61, the on-off valve mechanism 21 is operated to stop the supply of hydrogen gas so that the concentration causing the possibility of explosion does not reach the entire apparatus. It is intended for safety. Further, the discharge mechanism 62 may be operated at all times, and safety may be achieved only by the opening / closing operation of the on-off valve mechanism 21. In particular, the operation of the discharge mechanism 62 is also controlled based on the detection value of the hydrogen sensor 61 to save energy. Also good.
