Moreover, in description of each embodiment, the same code | symbol is provided about the part which has the same structure and the same effect, and the overlapping detailed description shall not be performed.

(Embodiment 1)
FIG. 1 is a configuration diagram of the entire system of the oxygen-enriched hot water supply apparatus according to the first embodiment of the present invention, and FIG. 2 is a configuration diagram of high-concentration oxygen generating means in the same embodiment. FIG. 3 is a diagram showing changes in the amount of horny water after normal bathing and bathing with dissolved oxygen-enriched water. In FIG. 1, a hot water supply device 1 sends a combustion air to a heat exchanger 5 having a water supply path 2, a hot water supply circuit 3, and a bath water supplemental circulation circuit 4, a burner 6 that heats the heat exchanger 5, and the burner 6. A burner fan 7 is provided. And the heat exchanger 5 and the burner 6 comprise the heating means of the water supply from the water supply path 2, and bathtub water.

  The water in the water supply channel 2 is heated by the heat exchanger 5 to become hot water, minerals are added by the mineral addition means 9 filled with pellets 8 granulated with mineral components, and the shower head 10 and the currant 11 which are terminals through the hot water supply circuit 3. Supplied from Moreover, the bathtub water circulated by the bath pump 12 provided in the additional cooking circuit 4 is heated by the heat exchanger 5, then passes through the additional cooking circuit 4, and is added to the bathtub from the additional cooking adapter 13 serving as a jet adapter in the bathtub. 14.

  The hot water supply circuit 3 is provided with a mixing means 16 for mixing the high concentration oxygen generated by the high concentration oxygen generation means 15, and the high concentration oxygen generation means 15 is a solid which is an oxygen ion conductor as shown in FIG. The solid electrolyte 17 is sandwiched between a pair of cathode-side electrode 18 and anode-side electrode 19 that support the electrolyte 17, and the cathode-side electrode 18 is exposed to air so that the solid electrolyte 17 and anode-side electrode 19 are housed in the case 20. At the same time, a DC power source 21 for passing a current between the cathode side electrode 18 and the anode side electrode 19 is provided. The gas generated from the anode side electrode 19 is diluted with air introduced from a slit 22 provided in the case 20 and is diluted with an oxygen pipe 23. It is conveyed to.

  The mixing means 16 is constituted by an ejector that draws air from the outside by causing a negative pressure action at the passage location when the fluid passes at a predetermined flow velocity, and the negative pressure side of the ejector is a check valve 24, a flow rate. It is connected to an oxygen pipe 23 that leads to the high-concentration oxygen generation means 15 through a control valve 25. Further, the forward circuit of the additional cooking circuit 4 includes a three-way valve switching means 26a for switching to an oxygen addition circuit 26 for connecting the forward circuit of the additional cooking circuit 4 to the hot water supply circuit 3 before and after the mixing means 16, and the mixing means. A two-way valve switching means 26b is provided which is connected to the downstream oxygen addition circuit 26 and is opened and closed in conjunction with the switching means 26a.

  The hot water supplied to the mixing means 16 can be switched between the hot water supplied from the hot water supply circuit 3 and the bathtub water circulated in the additional cooking circuit 4 by the switching means 26a and 26b, as shown by the arrows in the figure. Even when the bath water is circulated, high concentration oxygen can be mixed into the bath water via the mixing means 16, and hot water mixed with high concentration oxygen is ejected to the bath 14 via the additional cooking adapter 13. .

Next, the operation and action will be described. When the user tries to obtain hot water from the shower head 10 or the currant 11, the mineral 8 is granulated from the pellet 8 by contacting the pellet 8 granulated with the mineral component filled in the mineral addition means 9 and the hot water, and the mineral The hot water to which is added is supplied to the hot water supply circuit 3.

  When hot water is supplied to the hot water supply circuit 3 and the hot water passes through the ejector 16, the ejector 16 functions, and the oxygen pipe 23 connected to the negative pressure side of the ejector 16 becomes negative pressure. The generated air having high concentration oxygen flows in the oxygen pipe 23 and is mixed in the hot water of the hot water supply circuit 3 as bubbles.

  Since the oxygen pipe 23 is provided with the check valve 24 and the flow rate adjusting valve 25, the hot water of the hot water supply circuit 3 can be prevented from flowing back into the oxygen pipe 23, and the high concentration oxygen generating means 15 is protected. be able to.

  On the other hand, when the high-concentration oxygen generating means 15 causes a current to flow between the cathode side electrode 18 and the anode side electrode 19 by the DC power source 21, oxygen in the air receives electrons on the exposed cathode side electrode 18 and is ionized. Then, the solid electrolyte 17 can move as oxygen ions. The oxygen ions that have moved to the anode-side electrode 19 emit electrons and become oxygen gas, which can generate high-concentration oxygen. The amount of gas dissolved in the hot water is determined by the solubility and Henry's law, and the maximum amount of oxygen that can be dissolved in hot water at 40 ° C. is about 40 ppm, and is in contact with air with a normal oxygen concentration of 20%. In this case, it becomes about 8 ppm.

  The oxygen concentration of the dissolved air is very important for increasing the dissolved oxygen, and by mixing high concentration oxygen as shown in the present embodiment, it is possible to obtain hot water with an increased dissolved oxygen concentration. it can.

  Furthermore, by mixing high concentration oxygen with the ejector 16, high concentration dissolved oxygen water can be obtained in a short time, and the mineral component added by the mineral addition means 9 acts on the surface of the dissolved oxygen gas, and the gas is Since it can be stabilized, dissolved oxygen-enriched water can be obtained from the shower head 10 and the currant 11. When the bather uses the dissolved oxygen-enriched water as shower water, the dissolved oxygen penetrates through the stratum corneum and pores, and the cells can be activated.

For example, when used for the scalp, by supplying dissolved oxygen water from the pores to the hair roots, the cells of the hair roots are activated and a hair growth promoting effect can be obtained. Further, when used on the body, similarly, oxygen is absorbed into the skin as dissolved oxygen from the stratum corneum, time is plotted on the horizontal axis, and the amount of moisture is plotted on the vertical axis. As the graph of dissolved oxygen-enriched water bathing promotes the penetration of moisture into the skin and can activate the skin cells, and by activating the skin cells, the metabolism of the cells is promoted and the skin beautifying effect Obtainable.
That is, the dissolved oxygen-enriched water bath has a higher amount of stratum corneum moisture after 5 minutes of bathing compared to a normal bath and a bath that sucks high-concentration oxygen, so that the dissolved oxygen-enriched water has a higher moisture content to the skin. It shows that the penetration is promoted.

  When the user performs additional cooking, the bathtub water circulating through the additional cooking circuit 4 passes through the ejector 16 by detouring to the oxygen addition circuit 26 by the switching operation of the switching means 26a, 26b. As described above, oxygen is supplied to the bath water by the action of the ejector 16, and it becomes possible to supply the dissolved oxygen-enriched water into the bath water, and the skin beautifying effect of the dissolved oxygen-enriched water can be obtained. .

Furthermore, the high-concentration oxygen that has not been completely dissolved is released from the water surface of the bathtub 14 into the space, and when the bather inhales it, it becomes difficult to fall short of oxygen during bathing. . Moreover, the awakening effect by oxygen inhalation can be exhibited and the increase in heart rate can be suppressed. As a result, the effect of high-concentration oxygen can be maximized and beauty and healthy bathing can be performed.

  A switch (not shown) for switching the switching means 26a and switching the switching means 26b is provided in the bathroom, and the switching means 26a and 26b are switched by turning the switch on and off, and the bath Of course, it is possible to supply high-concentration oxygen to the bath water separately from the additional cooking by adopting a configuration in which the pump 12 is operated.

  In this way, high-concentration oxygen gas can be obtained from the anode side simply by passing an electric current between a pair of electrodes, so that dissolved oxygen-enriched water can be obtained in a compact configuration with a simple structure, hair growth promoting effect and cosmetic effect. Can be obtained. As a method for obtaining hair growth promotion effect and beauty effect during bathing, blood circulation promotion by massage and pore cleaning by sweating are effective, but by using oxygen-enriched hot water supply device, hair growth promotion and beauty effect are dissolved By obtaining oxygen-enriched water, bathers can easily and continuously carry out hair growth and beauty.

  In addition, a synergistic effect can be acquired also by combining the dissolved oxygen-enriched water by an oxygen-enriched hot water supply device and massage or sweating.

  In the present embodiment, the mixing means 16 is not limited to an ejector that sucks and mixes high-concentration oxygen air by negative pressure action, and hot water that circulates by pressurizing high-concentration oxygen air with a pump or the like. Of course, the structure mixed in bathtub water may be sufficient.

(Embodiment 2)
FIG. 4 is a block diagram of an oxygen-enriched hot water supply apparatus according to the second embodiment of the present invention, and FIG. 5 shows changes in the user's heart rate due to the operation of the oxygen-enriched hot water supply apparatus according to the second embodiment. FIG. The present embodiment is different from the above-described first embodiment in that the high concentration oxygen generating means is constituted by an oxygen-enriched film and the ejector is used as a pressure mixing means. The explanation will be focused on.

  The high-concentration oxygen generation unit 15 includes an oxygen-enriched film 27, a blower fan 28 that blows air from the outside to the oxygen-enriched film 27, and a vacuum pump 29. Oxygen is pressurized using a vacuum pump 29 and flows into the oxygen piping 23 connected to the negative pressure side of the pressurizing and mixing means 30 through the check valve 24 and the flow rate adjusting valve 25 to pressurize the pressurizing and mixing means 30. It is configured to be mixed. In other words, the pressurizing and mixing means 30 is configured by mixing the high concentration oxygen air with pressure using the vacuum pump 29 of the high concentration oxygen generating means 15 (part indicated by a dotted frame). .

  The operation and action of the oxygen-enriched hot water supply apparatus configured as described above will be described below. When hot water flows into the hot water supply circuit 3 in order to obtain hot water from the shower head 10 or the currant 11, the pressurizing and mixing means 30 in the present embodiment is the same as the ejector 16 in the first embodiment. Therefore, the oxygen pipe 23 connected to the negative pressure side of the ejector has a negative pressure. Furthermore, not only the pressure mixing means 30 but also the pressure by the vacuum pump 29 is added, and the air mixed into the pressure mixing means 30 is in a pressurized state, and the hot water of the hot water supply circuit 3 or the oxygen addition circuit The air in the oxygen pipe 23 can be mixed into the bathtub water flowing via the pressure 26 as fine bubbles by pressurizing and mixing.

On the other hand, when the pressure is reduced by the vacuum pump 29, the external air passes through the oxygen-enriched film 27, so that high concentration oxygen of about 30% can be obtained, and high concentration oxygen can be mixed into hot water as fine bubbles. The Since the oxygen pipe 23 is provided with the check valve 24 and the flow rate adjusting valve 25, the hot water of the hot water supply circuit 3 can be prevented from flowing back into the oxygen pipe 23, and the high concentration oxygen generating means 15 is protected. be able to.

  And by mixing high concentration oxygen under pressure, it becomes possible to mix as fine bubbles. By making fine bubbles, the contact area of gas and liquid can be increased, and dissolved oxygen-enriched water can be obtained in a short time. At the same time, dissolved oxygen can be dissolved to a supersaturated state by forming fine bubbles, and a higher concentration of dissolved oxygen-dissolved water can be obtained. Further, by supplying water containing fine bubbles, it is possible to obtain a cleaning effect of ultrasonic waves emitted when bubbles are repelled.

  Furthermore, since it is a fine bubble, it enters the pores and cleans it, so cleaning the pores makes it easier for dissolved oxygen to enter from the pores, and the synergistic effect of the fine bubbles and dissolved oxygen increases hair growth promotion and beauty effects. Can be increased.

  Further, the high concentration oxygen generating means is an oxygen enriched film, and the vacuum pump for passing external air through the oxygen enriched film is also used as a pump for pressurizing and mixing high concentration oxygen. By using the suction force of the pressurizing and mixing means for pressurizing and mixing high-concentration oxygen, high-concentration oxygen with an oxygen concentration of about 30% can be obtained simply by passing external air through the oxygen-enriched membrane. With the configuration, it is possible to obtain water having a high dissolved oxygen concentration at low cost.

  When bathers use dissolved oxygen-enriched water as shower water, the fine bubbles that could not be dissolved can be washed by the ultrasonic waves released when they hit the human body, and the fine bubbles can enter the pores. A cleaning effect can be obtained. Then, the pores are washed, so that the penetration of dissolved oxygen from the stratum corneum and pores can be promoted, and the cell activation can be further enhanced. For example, when used on the scalp, by removing dirt from pores with fine bubbles, penetration of dissolved oxygen-enriched water into pores is promoted, and dissolved oxygen water is supplied from pores to hair roots. Thus, hair root cells are activated, and a hair growth promoting effect can be obtained.

  In addition, when used on the body, the pores are similarly removed by the fine bubbles, the oxygen is absorbed into the skin as dissolved oxygen from the stratum corneum, and the penetration of moisture into the skin is promoted. By activating the skin cells, the metabolism of the cells is promoted, and a skin beautifying effect can be obtained.

  On the other hand, when high-concentration oxygen is mixed into the bathtub water circulating in the additional circulation circuit 4 by the switching means 26a and 26b, fine bubbles of high-concentration oxygen are ejected into the bathtub water, and the skin-beautifying effect of dissolved oxygen-enriched water In addition, the bath water can be clouded with fine bubbles, and a relaxing effect can be obtained visually. In addition, since fine bubbles are difficult to rise and disappear and exist between hot water and the human body, temperature stimulation to the human body is reduced, and an increase in heart rate is suppressed.

  Furthermore, high-concentration oxygen that could not be dissolved is released from the water surface of the bath water, and when the bather inhales it, it becomes difficult for oxygen to fall during bathing. it can. Moreover, the awakening effect by oxygen inhalation can be exhibited and the increase in heart rate can be suppressed. As a result, the effect of high-concentration oxygen can be maximized and beauty and healthy bathing can be performed. When the horizontal axis represents time and the vertical axis represents the heart rate, the level of the user's heart rate change during bathing shown in FIG. It is suppressed and has a small number.

  The pressurizing and mixing means 30 in the present embodiment is configured to have the function of the ejector 16 in the first embodiment, but pressurizes a gas containing only high-concentration oxygen without the ejector function. Even the pressurizing and mixing means in the form of mixing can be expected to have the same effect as that of the present embodiment, and the configuration is simplified by using the vacuum pump 29 of the high-concentration oxygen generating means 15 for pressurization. However, it may be a pressure mixing means having a separate pressure pump.

(Embodiment 3)

The high-concentration oxygen produced by the high-concentration oxygen production means 15 is mixed into the hot and cold water.

  Since the ejectors 32, 33, and 34 are connected to the high-concentration oxygen generating means 15 via check valves 35, 36, and 37, hot water and hot water for the hot water supply circuit 3 are added to the tubes 39, 40, and 41, respectively. The bath water of the circuit 4 can be prevented from flowing back, and the high-concentration oxygen generation means 15 can be protected.

In addition, when hot water is used simultaneously at a plurality of locations, the amount of high-concentration oxygen sucked by the ejector is reduced, so that sufficient high-concentration oxygen cannot be mixed. In this embodiment, the shower head Even when the bath pump 12 is in operation, in order to obtain sufficient dissolved oxygen-enriched water from 10 and the currant 11, it is detected by the flow rate detection means 42 that hot water is being used in the shower head 10 or the currant 11 In this case, the shutoff valve 43 is shut off to stop high concentration oxygen from being mixed into the bathtub water of the additional cooking circuit 4 by the ejector 34, and the high pressure to the ejector 32 provided immediately before the additional cooking adapter 13 is increased. The supply of concentration oxygen is cut off.

Further, not only high concentration oxygen is sucked by the ejector action of the pressurizing and mixing means 30, but also the pressure mixed by the vacuum pump 29 of the high concentration oxygen generating means 15 is added and the air mixed in the pressurizing and mixing means 30 is pressurized. In this state, the air in the oxygen pipe 23 can be mixed in the hot water of the hot water supply circuit 3 as fine bubbles by pressurizing and mixing it.

  On the other hand, by reducing the pressure by the vacuum pump 29, the external air passes through the oxygen-enriched film 27 and can obtain about 30% high-concentration oxygen, and high-concentration oxygen can be mixed into hot water as fine bubbles. . In this way, the dissolved oxygen-enriched water generated in the hot water supply body is transported into the bathroom by the hot water supply circuit 3, and the shower head 10 and the currant 11 or the switching means 26 a and 26 b are switched and ejected from the additional cooking adapter 13.

When the user tries to obtain hot water from the shower head 10, the hot water flows into the throttle portion 44 provided immediately before the shower head 10, and the hot water is pressurized again by the throttle portion 44, and the pressurizing and mixing means 30. Even if the fine bubbles once dissolved by the ejector action are deposited in the water supply channel and the bubble diameter becomes large, the bubbles are refined again immediately before jetting by pressurizing again with the constriction provided just before the terminal. And the dissolved oxygen concentration can be increased again. The other throttle portions 45 and 46 also operate in the same manner as the throttle portion 44 described above, so that the bubbles can be refined again immediately before jetting, and the dissolved oxygen concentration can be increased again.

  As described above, according to the present embodiment, when the distance between the hot water supply device main body and the bathroom is long, fine bubbles once dissolved by the pressure mixing means are deposited in the hot water supply path and the bubbles are deposited. Even when the diameter is increased, the bubbles can be refined again immediately before ejection, so that dissolved oxygen-enriched water can be obtained stably.

  Furthermore, by configuring the refinement means at the throttle part, the high-concentration oxygen mixed under pressure can be made into fine bubbles again by a shock wave at the terminal part, and dissolved oxygen-enriched water can be obtained with a simple structure. be able to.

  As described above, the oxygen-enriched hot water supply apparatus according to the present invention can obtain dissolved oxygen-enriched water by mixing high-concentration oxygen in the hot water as fine bubbles. It can also be applied to uses such as cultivation and cultivation equipment, drinking water and food reforming equipment, health and welfare equipment, and gas-liquid reaction equipment.
