Microbubble mixed water manufacturing method and microbubble mixed water manufacturing device

  The present invention relates to a method for producing a microbubble mixed water that significantly improves the bathing effect of carbonated springs such as blood circulation promotion and also has a microbubble effect, and a production device that can easily obtain the microbubble mixed water.

  Molding a mixture containing bicarbonate (sodium hydrogen carbonate or potassium hydrogen carbonate) and an organic acid by tableting or the like to form a foamable composition (solid) is a cleaning agent, bathing agent, bath water cleaning It is applied to products such as chemicals and fungicides for pools. These products (solids) have the advantage of quickly dissolving while generating carbon dioxide when they react with water, and at the same time increase the commercial value because they give consumers a comfortable feeling of use. In particular, in a bath preparation (sometimes referred to as a bath preparation), the blood circulation promoting effect of the generated carbon dioxide gas is actively used.

  On the other hand, microbubbles having a diameter of 0.05 mm or less, which are called microbubbles, are widely used for purification treatment of muddy water and wastewater, sterilization of domestic water, and the like, for example, muddy water treatment tanks such as water purification treatment facilities When microbubbles are generated, bubbles can be attached to the suspended substances in muddy water and separated by floating. When microbubbles are generated in closed water areas such as lakes and aquaculture ponds It has effects such as promoting the dissolution of oxygen in water.

  Conventionally, as a microbubble shower using microbubbles, a tap water pressure type using a swirling flow is known (see Patent Document 1).

  Moreover, what combined the technique which melt | dissolves the previous carbon dioxide gas generation | occurrence | production component in hot water, and the technique which performs the purification sterilization in a liquid by generating a microbubble is also known (for example, refer patent document 2).

  The technique of Patent Document 1 is provided with a structure in which a carbon dioxide generator such as various bathing agents is disposed in a gas-liquid mixing apparatus as a gas generator, and the discharge port side of the gas-liquid mixing apparatus is connected to a shower head. It is a technique that can be expected to have a health promotion effect such as a cleaning effect and blood circulation promotion by discharging hot water mixed with ingredients and microbubbles from a shower head.

  However, in the technique of Patent Document 2, the conventional bath agent components and tablets dissolve quickly due to dissolution by a tap water flow, the dissolution duration of the carbon dioxide generating bath agent is extremely short, and the foam diameter However, even if you touch the body, the action on the skin and blood vessels is difficult to occur, especially in the case of flowing hot water by the shower, the hot water discharged from the shower head will flow down quickly after touching the body, Compared to soaking in hot water in the bathtub, the contact time between the body and hot water is short and the contact area is also narrow, so in order to obtain the above-mentioned health promotion effect such as blood circulation promotion, the short dissolution duration is fatal We have determined that this is the case.

  From the above, the problem of the present invention is that the carbonic acid component can be continuously supplied during the normal use time of the shower even when the microbubble mixed water mixed with the carbonic acid gas component is discharged. Expected to exhibit sufficient effects of promoting health such as blood circulation by using a carbonated bath tablet component that has a microbubble size, a large amount of contact with the body, and a transdermal absorption efficiency of the carbonic acid component. An object of the present invention is to provide a method for producing microbubble mixed water and a microbubble mixed water producing apparatus.

According to the invention described in 1 or 2 above, even when microbubble mixed water mixed with carbon dioxide component is discharged by shower, the duration can be increased, and the carbon component can be efficiently transcutaneously promoted health promotion such as blood circulation promotion. The effect that the effect can be expected is exhibited.

In particular, even a conventionally known bathing agent composed of sodium hydrogen carbonate and an organic acid has a diameter and thickness of 7 mm or more and a hardness of 21 kg or more as in the present invention, and has a pH of 5 when dissolved in hot water. .5 to 8.5 Carbonated bath tablets, and by using this, the generation of the carbon dioxide component lasts for a long time, so the microbubble mixed water in which the carbon dioxide component is dissolved and contact with the body Time can be lengthened and the improvement of health promotion effects such as blood circulation promotion can be easily achieved.
In addition, according to the microbubble mixed water at the time of using the carbonated bath tablet of this invention, it is possible to remarkably suppress or eliminate the odor of tap water.
The operational effects of the present invention will be described in detail below.

  Conventionally, when a tablet is formed by combining bicarbonate and an organic acid, when dissolved in hot water, a strong neutralization reaction occurs while dissolving, large bubbles of carbon dioxide gas are generated, and the bubbles are merged and become large. Thus, the carbon dioxide gas quickly escapes into the air, and there is a disadvantage that the concentration of carbon dioxide dissolved in the hot water is extremely low.

  Carbon dioxide is inherently difficult to dissolve in hot water, and its solubility decreases further as the temperature rises.The concentration of carbon dioxide in hot water is infinitely low, so there is no thickness of water in the shower. There was a tendency to escape inside, and it was not possible to make high concentration carbonated water in the shower.

  Therefore, the inventors found that the concentration of carbon dioxide in shower water was extremely low, the amount of carbon dioxide dissolved in blood vessels by percutaneous absorption was low, and the bathing effect such as warming the body was not obtained at all. It was.

It is said that natural carbon dioxide springs have a carbon dioxide gas concentration of 1000 ppm or more, but this is because carbon dioxide is dissolved at a high concentration under high pressure underground and is often weakly acidic. The However, in our study, the weak acidity of natural carbonated springs is not only due to the acidic component, but the PH value is weakly acidic. In addition, they have found that there are many cases of weak acidity that can be easily neutralized by touching a little neutral or alkaline substance.

  In general, natural carbonated springs are weakly acidic, and the carbon dioxide concentration is overwhelmed by the general idea that carbon dioxide concentration is called 1000 ppm or more. It was common to have foam on the skin, but when the bath agent is acidic, the carbon dioxide gas has the property of volatilizing out of the liquid as a gas, the diameter of the foam is large, the thickness of the water is It was found that in a shower without gas, gas was released in the air instantly, and there was almost no carbon dioxide in the hot water, and the body warming effect could not be obtained.

  Therefore, the inventors of the present invention continuously generate carbon dioxide in the shower hot water at a micro size in which the carbon dioxide easily dissolves in hot water, neutralize the pH after dissolution, Let the concentration of a sufficient carbonic acid component dissolve continuously in the shower water without letting it escape into the air, and let the shower water in which this carbon dioxide dissolves travel through the skin and absorb it quickly and easily from the skin into the blood vessels. Must react to cause the conversion to bicarbonate ions, and in order for carbon dioxide to be absorbed into the blood vessels from the skin, the bath agent must be neutral as close as possible to the pH value of the body fluid I also found out.

  That is, as a result of detailed examination of the effects of natural carbonated springs by the present inventors, even if the spring water is weakly acidic in natural carbonated springs, it is not due to acidic components but weak acidity without titer due to slight negative ion dissociation. (Acid that is not excessive organic acid.) Carbon dioxide is neutralized and absorbed into neutral blood as bicarbonate ion just by touching body fluid such as skin and hair. It was not absorbed by the skin, and it was not only found that the conventional carbon dioxide gas was absorbed directly through the skin, and it was explained that the carbon dioxide gas was dissolved in the blood. For the wrong explanation, the commercially available bathing agent imitates the value of natural carbonated spring by the PH value, makes it too weak to make the carbon dioxide gas foam easily by adding an excess of organic acid, and the foam diameter is large even if only foaming is done. Bubbles for acid He immediately escaped into the air and could not neutralize with body fluids even if he touched the skin, and as a result, he could not become bicarbonate ions, and could not be absorbed through the skin and dissolved in the blood vessels. I found out.

  In general, the explanation of the effects of carbonated springs describes that carbon dioxide gas is directly absorbed through the skin, but this is a complete error: "If carbon dioxide gas is absorbed directly into the blood vessel and dissolved in the blood vessel. It was proved that even if the experiment was conducted in a room filled with carbon dioxide, it was not absorbed in the air.

  Most of the blood and body fluids on the skin are neutral and have a pH of about 7.2 to 7.4. If the body fluid is neutral, the carbonate component is chemically present only as bicarbonate ions, the component that is absorbed into the blood vessels through the skin is bicarbonate ions, and the dissolved state in the blood is only bicarbonate ions. There should be no.

Even so, even if tablets with reduced hardness in a neutral or weakly alkaline state were designed as bathing agents, according to the study by the present inventors, in fact, sufficient neutralization foaming reaction did not occur, and extremely weak foaming No matter how much PH is neutral, no foaming of carbon dioxide gas can be obtained, and the reaction is carried out in a tablet with high hardness to obtain foaming of sufficiently fine micro-sized carbon dioxide gas. Discovered the fact that by returning to bicarbonate ions in the same neutral state as the body fluid outside the tablet, only bicarbonate ions via this carbon dioxide gas are percutaneously absorbed during the skin contact time of a very short shower Because the same effect was not obtained with neutral shower water by simply dissolving sodium bicarbonate, the foaming reaction inside the tablet with high hardness of a certain size and a certain value or more Carbonic acid It is important in the sense of generating water, and the carbon dioxide generated by the dissolved pH of the shower water is changed to bicarbonate ions, which are easily dissolved in blood vessels by percutaneous absorption, increasing blood circulation, warming the body, etc. It is estimated that the effect is close to that of natural carbonated springs.

According to the regulation of pH, it is appropriate to measure the PH as a PH at a concentration of about 0.05% to 0.5% in terms of dissolution of the tablet according to the actual condition of the shower water.
This PH measurement is preferably PH immediately after dissolution. Even if the pH is neutral, bicarbonate ions in the hot water volatilize the carbon dioxide gas and gradually rise. For example, the pH of water immediately after dissolution is 7. Even if it is 0, it becomes about 7.5 after 24 hours. If air is introduced and foamed, the carbon dioxide gas will volatilize and PH may exceed 8.5. Therefore, the regulation of PH in the present invention is set immediately after dissolution of carbonated bath tablets in hot water.
The effect of the present invention will be further described in detail.

According to the reference invention shown in the above (1) or (7) , since the second microbubble generating part is added, a two-stage microbubble generating effect can be obtained. A synergistic effect can be exhibited.

According to the reference invention shown in the above (2) or (8) , according to the configuration in which the microbubble generating part is provided upstream of the air introducing part of the second microbubble generating part, the microbubble in which the carbon dioxide component is dissolved Since the second microbubbles are further mixed into the mixed water, the degree of mixing of the carbon dioxide component and the microbubbles is increased.

  Moreover, according to the structure which provided the microbubble generation | occurrence | production part downstream from the air introduction part of the 2nd microbubble generation | occurrence | production part, the microbubble generation | occurrence | production part by the hot water which became the microbubble mixed water by the 2nd microbubble generation | occurrence | production part Since the carbonated spring tablet accommodated in is dissolved, the solubility of the carbonated spring tablet is increased.

According to the reference inventions shown in the above (3) and (4) , it becomes possible to continue to generate carbon dioxide bubbles of a micro size having a certain diameter or less efficiently for a long time, and the carbon dioxide dissolved in the hot water is converted into bicarbonate ions. As a high concentration.

According to the reference invention shown in said (5) , a transparent shower hot water can be maintained, without making a shower hot water cloudy.

According to the reference invention shown in the above (6) , it can be seen that the carbonated spring tablet is dissolved depending on whether the discharged hot water is colored and / or fragrant, and the hot water becomes uncolored. By becoming unscented, it can be grasped by the five senses that all carbonated spring tablets have dissolved. Therefore, not only can the effect time of the new carbonated bath tablet be easily understood, but also the five senses can recognize that the carbon dioxide component is mixed with the hot water by coloring and / or aroma of the hot water.

According to the third aspect of the present invention, the carbonated spring tablet is disposed at an arbitrary position of the hot water passage in each component of the water hose connected to the shower head, the shower body, and further the shower body. Thus, hot water mixed with a carbon dioxide component and microbubbles can be discharged.

According to the invention shown in 4 above, the carbonated spring tablet can be accommodated and added easily and quickly.

According to the invention shown in 5 above, the presence or absence of the carbonated bath tablet accommodated in the carbonated spring tablet accommodating portion and the degree of dissolution can be easily grasped visually.

According to the invention shown in 6 above, whether or not the carbonated bath tablet is dissolved in hot water can be easily grasped visually from the outside.

  Hereinafter, a microbubble mixed water manufacturing method (hereinafter sometimes simply referred to as a manufacturing method) and a microbubble mixed water manufacturing device (hereinafter also simply referred to as a manufacturing device) according to the present invention will be described. Based on

This is a technique that can be expected to have a health promotion effect such as a cleaning effect and blood circulation promotion by discharging (shower discharge) from the discharge port (shower discharge port).

  The microbubble generator 2 is connected to a water supply device such as a water heater, a water tap, a water supply device, a hot water tap, etc., which is a water supply path between the water inlet and outlet and a water passage between them. Dissolving the carbonated bath tablet T accommodated in the microbubble generator 2 by hot water passing through the water passage by being provided at any location in the water supply path from the start end of the hose 3 to the shower outlet 13. The carbon dioxide gas generated by this dissolution becomes microbubbles (fine bubbles) in the hot water and mixes with the hot water to form microbubble mixed water.

Next, an example of a storage configuration of the carbonated bath tablet T in the microbubble generator 2 will be described.
The microbubble generating unit 2 is configured to have a tablet storage unit 21 provided with a partition structure through which hot water such as a mesh body can pass on the upstream side and the downstream side of the storage position of the carbonated bath tablet T, and in this storage state By being arranged in the hot water passage, it dissolves by contact with hot water passing through the water passage, generates carbon dioxide, and becomes microbubbles.

The arrangement position of the microbubble generator 2 is preferably any of the following (1) to (6).
(1) Configuration arranged in the shower head unit 11 (for example, the configuration shown in FIG. 2A)
(2) Configuration arranged in the shower body 12 (for example, the configuration shown in FIG. 4 which is an embodiment described later)
(3) Between the shower head part 11 and the shower body part 12 (for example, the configuration shown in FIG. 2B), or a joint part between the shower head part 11 and the shower body part 12 or straddling the joint part (For example, the configuration shown in FIG. 2C)

(6) Configuration disposed in the middle part of the hose 3 connected to the shower body 12 (for example, the configuration shown in FIG. 2B)

  In the case of the configuration shown in (3) above, the microbubble generator 2 may be built in or incorporated in the terminal portion of the hose 3, or the terminal portion of the hose 2 may be connected to the microbubble generator 2, It is good also as a structure (structure of the Example shown in FIG. 1) which connects the terminal part of the hose 3 to the microbubble generation | occurrence | production part 2 connected or couple | bonded with the shower trunk | drum 12. As shown in FIG.

  In the case of the configuration shown in (4) above, the microbubble generator 2 may be built in or incorporated in the start end portion of the hose 3, or the start end portion of the hose 3 may be connected to the microbubble generator 2, It is good also as a structure which connects the start end part of the hose 3 to the microbubble generation | occurrence | production part 2 connected or couple | bonded with the faucet part.

  In the case of the configuration shown in (5) above, the microbubble generating unit 2 may be built in or incorporated in the middle of the hose 3, or the hose 3 may be composed of two (plural) units and the two hoses 3 relayed. It is good also as a structure which makes the microbubble generation | occurrence | production part 2 incorporate or thru | or incorporate in a connection part, or makes the microbubble generation | occurrence | production part 2 function as a connection member of the two hoses 3. FIG.

  According to the structure which attaches the tablet storage part 21 of the microbubble generation | occurrence | production part 2 to the shower head part 11 or the shower trunk | drum 12 so that attachment or detachment is possible, accommodation and addition of the carbonated bath tablet T become easy.

  In addition, the microbubble generator 2 is not limited to a configuration that is incorporated in the manufacturing device 1 as a part of the components of the manufacturing device 1 as shown in the above embodiment, and is separate from the shower head unit 11 and the shower body 12. It can also be set as the structure, and it can also be set as the structure arrange | positioned in the hot water flow path by connecting to the shower head part 11, the shower trunk | drum 12, or the hose 3. FIG.

  In particular, it is easy and quick to store and add the carbonated bath tablet T by making the microbubble generator 2 an attachment type. When setting it as an attachment type structure, it is good also considering the microbubble generation | occurrence | production part 2 whole as an attachment type structure, and only the tablet accommodating part 21 which is a part which accommodates the carbonated spring tablet T can also be set as an attachment type structure.

  Furthermore, the microbubble generation part 2 is formed of a transparent material such as a transparent synthetic resin material, so that the carbonated bath tablet T accommodated in the microbubble generation part 2 can be viewed from the outside of the manufacturing device 1. It can also be. According to such a configuration, the presence or absence of the carbonated bath tablet T accommodated in the microbubble generator 2 and the degree of dissolution can be easily grasped from the outside of the production device 1.

  Furthermore, by forming at least a part of the shower head part 11 and / or the shower body part 12 and at least a part of the members constituting the water passage inside the shower head part 11 and / or the shower body part 12, It can also be set as the structure which can visually observe the hot water which flows through the inside of a water passage. According to such a configuration, it is possible to easily grasp from the outside of the production device 1 whether or not the carbonated bath tablet is dissolved in hot water or not, that is, whether or not microbubbles are generated.

  Next, the carbonated bath tablet used in the present invention will be described in detail.

As described above, the carbonated bath tablet used in the present invention is composed of bicarbonate and an organic acid, and is compression-molded in the presence of polyethylene glycol. When the diameter and thickness are 7 mm or more and the hardness is 21 kg or more, it is dissolved in water. It is assumed that the PH is 5.5 to 8.5. By using a carbonated bath tablet under these conditions, the carbon dioxide component is generated in a micro size and the dissolution lasts for a long time of about the usage time of the shower, and the generated carbonate component is sufficiently absorbed through contact with the body. It is possible to obtain an ionic state that is easy to be performed, and even a shower that is not bathing can sufficiently improve the health promotion effect such as blood circulation promotion.

  Furthermore, the preferable structural example of a carbonated bath tablet is explained in full detail.

  In the present invention, the neutralization reaction can be generated in a tablet with a certain size and high hardness, and the foaming reaction can be efficiently and maximally and continuously performed by dissolving in a PH environment that can generate micro-sized bubbles and is easily absorbed through the skin. The concentration of carbon dioxide dissolved in water is increased for a certain period of time, and the dissolved carbonic acid component can be made into a high concentration of bicarbonate ion to facilitate the percutaneous absorption of the carbonic acid component into the body.

  In the present invention, when the carbonated bath tablet is dissolved in hot water, micro-sized carbon dioxide gas is generated at an appropriate rate inside the tablet with a constant size and high hardness, and the dissolution of carbon dioxide gas in the hot water is maximized. In tablets, the aqueous solution is neutral to weakly alkaline (PH 5.5 to 8.5), but the dissolved carbonate component is changed to bicarbonate ions. Since it is easily transdermally absorbed, the bathing effect such as health and beauty is further enhanced, and products with high added value can be provided.

  The effect of the present invention is that when the amount of polyethylene glycol (PEG) and the amount of organic acid are defined relative to bicarbonate, each is mixed under the conditions within a certain ratio, and compressed to form a tablet. By making the diameter and thickness of the material 7 mm or more, making the hardness as high as 15 kg or more, and changing the pH after dissolution from 5.5 to 8.5, the effect is maximized.

  Furthermore, in the present invention, since the mixture A of the bicarbonate is a granulated material prepared by coating with polyethylene glycol using a fluidized bed, the effect is greatly exerted, and the micro size is formed inside the tablet. In order to generate the foam, it is preferable that the diameter and thickness of the tablet are 7 mm or more, respectively, since the effect is greatly exerted.

Further, since citric acid is used as the organic acid, the neutralization reaction is more effective than when other organic acids (succinic acid, fumaric acid, malic acid, etc.) are used. The amount of citric acid with respect to the granulated product A of bicarbonate and the amount of anhydride such as anhydrous sodium carbonate can be specified to make the tablet a certain size and above a certain hardness. By doing so, the neutralization reaction occurs in the tablet, and the effect that the dissolved aqueous solution can be changed from neutral to weakly alkaline is exhibited.

  When granulating bicarbonate in a fluidized bed to obtain a granulated product A, the hardness of the tablet can be remarkably increased when a mechanical fluidized bed granulator that does not substantially use air as a stirring action is used. As the fluidized bed of the mechanical stirring method, since the powder is flowed using mechanical blades such as a propeller without using air for stirring, the moisture brought in from the humid air during granulation It is possible to make a vacuum with a decompression pump during granulation without lowering the amount of polyethylene, and it is possible to granulate by lowering the amount of polyethylene glycol. It can be used effectively, and is preferably used to make the tablet high in hardness.

  A mechanical fluidized bed granulator that does not substantially use air as a stirring action is a mixer that arranges a chamfered shovel in a horizontal drum, causes centrifugal diffusion and vortex flow, and causes three-dimensional flow. For example, it is sold in the market as a product made in Germany Leedige or Matsuzaka Giken.

  More preferably, the granulator is equipped with a vacuum pump for reducing the pressure. That is, it is preferable in order to improve the effect of the present invention by reducing the pressure during cooling and operating so that even a little moisture can fly. Furthermore, it is preferable to have a chopper for preventing the granulated granules from becoming coarse particles upon cooling. That is, by operating the chopper at the time of cooling and sizing, the effect of reducing the diameter of the generated carbon dioxide bubbles by the micro size is exhibited, which is a more preferable granulation method.

A more preferable production method used in the present invention is to granulate bicarbonate by a fluidized bed granulator using polyethylene glycol and a mechanical stirring method, and to the granulated product a certain amount of citric acid and anhydrous carbonate. Add sodium (or anhydrous potassium carbonate) and polyethylene glycol, and after mixing, compress and mold at high pressure so that the diameter and thickness are each 7 mm or more and the hardness is 21 kg or more. By obtaining, the effect of this invention is exhibited largely.

  Of course, the mixture B mainly composed of citric acid is preferably granulated with polyethylene glycol, but from the viewpoint of cost, it is desirable to produce either one by granulating one and mixing the other.

  The PEG used preferably has an average molecular weight of 4,000 to 8,000 in that the effect is achieved. PEG having an average molecular weight of about 6000 is preferable for the granulation result from the viewpoint of improvement of molding stability, wrinkle adhesion resistance, capping, tablet molding speed by a compression molding tablet machine such as a rotary tableting machine. When dissolved in water, the carbon dioxide component can be dissolved to the maximum in bicarbonate ions, and the greater the thickness and diameter, the more significant the effect.

  The ratio of polyethylene glycol to 100 parts by mass of bicarbonate (sodium bicarbonate or potassium hydrogen carbonate) in mixture A is preferably 2 to 20 parts by mass, particularly preferably 3 to 10 parts by mass, and the ratio of PEG is the above amount. If the amount is less, the carbon dioxide bubble diameter increases and the foaming time is shortened, and the carbon dioxide component dissolved in water may not be increased. On the other hand, if the amount of polyethylene glycol is increased, the amount of foam generated is reduced. The amount of carbon dioxide that is suppressed and dissolves in the same way may be reduced.

Moreover, after obtaining the granulated product A, in the step of adding an organic acid, by adding an anhydride such as anhydrous sodium carbonate, anhydrous potassium carbonate, anhydrous calcium carbonate, or anhydrous magnesium carbonate, the effect of the present invention can be further improved. It was found that the effect of being able to be remarkably exhibited and capable of maintaining the foaming amount larger and lasting for a long time while the bubble diameter of the carbon dioxide gas is made to be an optimal small size is obtained.

  Moreover, as an effect of this anhydride, it was found that the addition of anhydrous sodium carbonate is a compound that exhibits a more preferable effect.

  In addition, in the present invention, when citric acid is added as an organic acid, the citric acid is not granulated, and when the compression molding is performed only by adding polyethylene glycol to the granulated product A and citric acid and mixing them, It was found that the foam of the size was foamed for a long time, and the carbon dioxide component dissolved in water could be maximized, and a good tablet could be obtained. In this case, it has been found that the manufacturing method is desirable because the process can be largely omitted and the cost effect is also obtained.

  The ratio of polyethylene glycol to citric acid used in this production method is 0 to 15 parts by mass with respect to 100 parts by mass of citric acid.

  In the mixture B composed of citric acid, if granulation is not performed using a fluidized bed, the effect of the present invention can be obtained without adding PEG, but the tableting property may be deteriorated, and the tableting property is improved. Therefore, it is preferable to add PEG, and the ratio is preferably 1 to 10 parts by mass. If it is more than this, there is a drawback that the quality stability and foamability are deteriorated, and the cost is also increased.

  The anhydride used in the present invention is preferably selected from anhydrous sodium carbonate and anhydrous potassium carbonate. By using only 1/10 to 1/100 of the amount of bicarbonate, particularly 1/10 to 1/50, the effect of the present invention was preferably exhibited. In particular, anhydrous sodium carbonate is an example of an anhydride that exhibits the maximum effect.

  Furthermore, a lubricant for tableting can be added, citric acid and anhydride are added to the bicarbonate granulated product A, polyethylene glycol is further added and mixed, and a release agent is further used. However, as this release agent, insoluble substances such as sucrose and magnesium stearate are generally used in most cases. These non-dissolving release agents have been actively used to make the hot springs turbid, but when microbubbles are generated with a shower head, the pores of the shower are clogged, causing an undesirable phenomenon. In the present invention, the tablet according to the present invention is completely dissolved by including one kind selected from sodium n- (normal) octane sulfonate, sodium lauryl sulfonate, sodium lauroyl sarcosinate, sodium myristoyl methylalanine and the like as a particularly preferable compound. Transparent shower water can be obtained, the shower head is not clogged, daily cleaning is easy, tablets can be produced continuously and stably for a long time, and high speed compression molding is possible. preferable. In addition, when the tablet according to the present invention is dissolved in hot water, it is used as the most preferable release agent in order to cause micro-size foaming and maintain the washing effect of the hot water after dissolution.

  The granulation of the tablet used in the present invention is a preferable preparation method in which a tablet is obtained by compression molding. In this case, it seems that citric acid substantially becomes the granulated product B in the mixing step. Even in the product A, if the bicarbonate and polyethylene glycol are granulated at the temperature of the present invention, it is not essential to add polyethylene glycol in the citric acid addition step.

  Furthermore, other components (additives) can be mixed as necessary. Granule A uses sodium bicarbonate or potassium bicarbonate as the main component as bicarbonate, and other additives such as fragrances, pigments, surfactants, and anhydrous anhydrides such as anhydrous sodium carbonate as required. Is mentioned.

Citric acid or citric acid mixture B and citric acid granulated product B include anhydrous additives such as sodium carbonate, fragrances, pigments, surfactants and polyethylene glycol as desirable additives.

  For compression molding for producing tablets, a known compression molding machine can be used without any particular limitation. For example, a hydraulic press machine, a single shot tableting machine, a rotary tableting machine, a briquetting machine, etc. can be used. . The size of the punch used in this tableting machine or the like is preferably 7 mm or more when the punch is circular, and when the punch is a triangle or quadrangle, the diameter is 7 mm or more in terms of a circular punch. Those are preferred. The same applies to the thickness of the ridge. When obtaining a round tablet product, the diameter of the tablet is preferably 7 mm or more, and the thickness is also preferably 7 mm or more. When the tablet is a triangle or quadrangle, the diameter and thickness are converted into a round tablet. Each of these is preferably 7 mm or more.

As described above, the tablet does not necessarily need to be a circle having a flat surface, and the shape of the tablet is not limited to an oval shape, a tablet, or a sphere as long as the solid is 7 mm or more and the hardness is 21 kg or more.

  Any shape may be used as long as micro-size foaming occurs slowly in a hard solid and carbon dioxide is dissolved more efficiently in the liquid. Particularly preferred hardness is 25 kg or more, and the higher the hardness, the higher the tablet. It is presumed that carbon dioxide gas in the bath is easily dissolved by the generation of carbon dioxide gas therein, and the bubble diameter and the like are presumed to be fine, and a preferable result is obtained.

  The hardness in the present invention is a hardness (Vickers hardness HV) measured using a micro Vickers hardness tester Mitutoyo HM-221 which is one of the hardness testers used in Examples of many patent specifications. , Kg / mm2).

  As mentioned above, although the carbonated bath tablet used for this invention was demonstrated, the carbonated bath tablet used for this invention is not limited to the said Example, Other aspects can also be taken within the scope of the present invention.

  As described above, the carbonated spring tablet may include a coloring component and / or an aromatic component. According to such a configuration, the user can easily grasp and feel the state in which the carbon dioxide component is mixed in the hot and cold water discharged from the shower. That is, according to the configuration containing the coloring component, it can be seen that the carbonated spring tablet is dissolved by being colored by the colored component in which the hot and cold water discharged from the shower is dissolved, and according to the configuration containing the aromatic component. It can be seen that the carbonated spring tablet is dissolved by releasing the fragrance by the aromatic component dissolved in the hot water discharged from the shower, and the carbonated spring tablet is completely dissolved and disappears when the hot water becomes transparent or unscented. Can be understood. Therefore, not only can the storage time of the new carbonated spring tablet be easily understood, but also the five senses can recognize that the carbon dioxide component is mixed with the hot and cold water by coloring and / or aroma.

As a coloring component that can be contained in the carbonated spring tablet, a publicly known natural or synthetic coloring agent / coloring agent used for a bath agent can be used without any particular limitation.
Moreover, as a fragrance component which can be contained in a carbonated spring tablet, a publicly known natural or synthetic fragrance / fragrance used for bathing agents, facial cleansers / soaps and the like can be used without any particular limitation.

In particular, in a mode in which a carbonated bath tablet contains a coloring component, the above-described tablet container is formed of a transparent material, or at least a part of the shower head and / or the shower body and the interior thereof. By using together with the structure which formed at least one part which comprises this water flow path with the material which has transparency, the presence or absence of a carbonated spring tablet and the extent of melt | dissolution can be grasped | ascertained more easily.

  Furthermore, the carbonated bath tablet may have a configuration in which a plurality or a plurality of carbonated bath tablets are set as one set. In the case of set sales, the same type of carbonated spring tablet set may be used, multiple types such as those with different colors and fragrances, colorless and unscented, or those with different carbon dioxide generation amount and carbon dioxide generation duration It is good also as an assortment.

According to the configuration in which the carbonated bath tablet having the above configuration is accommodated in the manufacturing device according to the present invention, hot water mixed with carbon dioxide components as microbubbles can be discharged by shower. The hot water discharged from the shower has a high health promotion effect such as blood circulation promotion by the synergistic effect of the microbubbles and carbon dioxide component, and this effect is prolonged by using a carbonated bath tablet with a tablet hardness of 21 kg or more. Can be maintained.

  As mentioned above, although the manufacturing method and manufacturing apparatus of the microbubble mixed water which concern on this invention were demonstrated based on the Example, it shall be set as the structure which further adds a 2nd microbubble generation | occurrence | production part to the water passage of the manufacturing apparatus which has the said structure. Can do. According to such a configuration, a two-stage microbubble generation effect is produced by the generation of two microbubbles, so that a health promotion effect such as blood circulation promotion can be further exhibited.

Hereinafter, a manufacturing device (reference invention) to which a second microbubble generator is added will be described with reference to FIGS. 4 and 5.

  In the manufacturing device 1 shown in FIG. 4, the second microbubble generating unit 4 is provided in the shower body 12 of the shower device 10, and the specific configuration of the second microbubble generating unit 4 is the manufacturing device. A swirling flow is imparted to the hot water introduced into the water flow passage 14 in the manufacturing device 1 (in the shower barrel 12 in this embodiment), and air is introduced into the swirling flow through an air introduction pipe 41. Air is introduced from the introduction port 42, and the introduced air is sheared and broken by the swirl flow to be refined and discharged from the shower discharge port 13 of the manufacturing device 1 together with hot water as microbubbles (fine bubbles). . Needless to say, a rectifier may be provided immediately before discharge as required.

  In the present embodiment shown in FIGS. 4 and 5, the microbubble generator 2 in which the carbonated bath tablet T is accommodated is an air inlet 42 which is an air inlet to the swirling flow in the second microbubble generator 4. It is arrange | positioned upstream. It is preferable that the tablet accommodating part 21 of the microbubble generating part 2 in the present embodiment is configured to be detachably attached to the shower body part 12 from the outside. When the carbonated bath tablet T accommodated in the tablet accommodating portion 21 is dissolved by performing shower discharge for an arbitrary period or is replaced with another type (other composition) of the carbonated bath tablet T, the tablet accommodating portion. By pulling out 21 from the shower barrel 12, a new or other type of carbonated spring tablet T can be accommodated in the tablet accommodating portion 21 and reattached.

In the reference invention shown in FIGS. 4 and 5, the tablet container 21 is arranged in the shower body 12 upstream of the air introduction part to the swirl flow. Of course, it may be arranged downstream.
The following is mentioned as another structural example of the microbubble generating part 4, for example.
In the case of the shower device 10 adopting a configuration in which the shower discharge port 13 (for example, a perforated cap of the shower head unit) is detachably fixed to the shower head unit 11 by screwing or the like, In order to accommodate the carbonated spring tablet T in the tablet accommodating portion 21 in use, the perforated cap may be removed by rotating or rotating.

  Hereinafter, each configuration of the second microbubble generating unit 4 will be further described.

First, a configuration example for generating microbubbles will be described.
The hot water introduced from the hose 3 connected to the shower body 12 is given a swirling flow in the water passage 14 in the shower body 12, and air is self-sucked into the swirling flow, and the self-sucked air is swirled. The liquid is sheared and broken down by a flow to be refined and discharged as microbubbles (for example, fine bubbles of about several tens of μm) together with hot and cold water from a shower discharge port 5 provided in the shower head unit 11. That is, the microbubble generating means of the second microbubble generating section 4 is different from the microbubble generating means generated by the generation of carbon dioxide gas by the dissolution of the carbonated spring tablet T in the microbubble generating section 2 described above, by the shearing breakage of the swirling flow. It is a means for generating microbubbles.

  A swirling water channel member 43 is disposed in the upstream portion of the water passage 14 in the shower body 12, and a swirling water channel 44 for swirling the flow of hot water is formed in the swirling water channel member 43. An air introduction pipe 41 having an air introduction port 42 for introducing air into the downstream hot water is connected. The air introduction pipe 41 introduces air from the air introduction port 42 into the water passage 14 by taking in air from the outside of the shower body 12.

The swirling water channel 44 formed in the swirling water channel member 43 is formed of at least one spiral groove that spirally swirls in the direction of water flow. In this reference example, as shown in FIG. A spiral groove is formed. Hot water introduced into the water passage 14 of the shower body 12 via the hose 3 is formed in the swirling water channel member 43, which is a component of the swirling water channel 44, through the water channel holes 45 and 45 formed in the swirling water channel member 43. -The flow of hot water is converted into three swirl flows by entering the swirl water channel 44 composed of three spiral grooves through 45.

  The air introduction pipe 41 has an air introduction port 42 that introduces air into a substantially central portion of the swirling flow of the hot water that is swirled by the swirling water channel 44, and the swirling that becomes negative pressure by the swirling flow of the hot water. By introducing air into the hot water from substantially the center of the flow, air is quickly mixed into the hot water. In introducing air, a self-priming configuration in which air is sucked into the hot water by the negative pressure of the swirling flow is preferable, but a configuration in which pressure is introduced by an air feeding means such as a pump may be used. The introduced air is not limited to general air (outside air), and other gases such as pure oxygen and ozone can be used.

  The swirling flow of hot water is discharged from the shower discharge port 13 of the shower head unit 11 in a state where the microbubbles are mixed.

As mentioned above, although the structural example of the 2nd microbubble generation | occurrence | production part 4 was demonstrated, reference invention is not limited to the said reference example, Other aspects can also be taken within the scope of the present invention. In the embodiment, it is formed of three spiral grooves, but the present invention is not limited to three, and may be one or two or four or more. However, it is preferable that the number is equal to or more than three.

As a mechanism for generating microbubbles by the second microbubble generator, a publicly known mechanism or means can be adopted without any particular limitation. For example,
A device for generating microbubbles in a shower head incorporating a venturi tube (tube having a partially constricted structure) or an orifice plate (a donut-shaped plate having a hole in the center) (Japanese Patent Laid-Open No. 2006-116518) , Japanese Patent Application No. 2006-77553, etc.)
A device that discharges a liquid in which a base is mixed into a main body pipe arranged in the liquid and collides with a collision wall arranged on the downstream side in the main body pipe to generate microbubbles (Japanese Patent Laid-Open No. 2005-334869),
An apparatus for generating microbubbles by blowing compressed air into water through a fine mesh member or a porous plate with a pneumatic source such as an air pump (JP 2006-68631 A).
An apparatus (such as Japanese Patent Application Laid-Open No. 2003-126665) that creates a spiral water flow and shears air with this water flow to generate microbubbles,
Or the configurations described in Japanese Patent No. 4019154, Japanese Patent Application Laid-Open No. 2007-89710, Japanese Patent Application Laid-Open No. 07-241494, and the like.

[Table 1]

As is apparent from Table 1, if the tablet hardness according to the present invention is not less than a certain value, the tablet diameter and thickness are not less than a certain value, and the hot water pH immediately after dissolution of the tablet is within the present invention, It can be seen that the operational effects peculiar to the present invention can be seen in such hot water.

[Example-1]
[Experiment 1] and [Comparative Experiment 1]
Production of the three types of carbonated spring tablets having the above-mentioned characteristics and the above-mentioned characteristics produced by the above-mentioned production method, and three comparative carbonated-spring tablets having the above-mentioned characteristics produced by the above-mentioned production method, as shown in FIG. In the state accommodated in the tablet accommodating part 21 of the micro bubble generating part 2 of the vessel 1, shower discharge is performed using hot water at a temperature of 40 ° C. and water is supplied under the same conditions as during normal bathing. The duration, i.e. the time taken for the carbonated spring tablet to completely dissolve, was measured. In addition, about the carbonated spring tablet, the shape was changed as much as possible so that each of the samples was about 30 grams, and the tablet was used as long as the tablet could be put in.

The type and hardness of the carbonated spring tablet for the present invention will be described below.
J5 Hardness = 21kg
J8 Hardness = 30kg
J10 Hardness = 120kg

The kind and hardness of the carbonated spring tablet for comparison are described below.
J01 Hardness = 3.3kg
J05 Hardness = 6.6kg
J06 Hardness = 7.8kg

  In addition, about both the carbonated spring tablet for this invention and the carbonated spring tablet for a comparison, in order to grasp | ascertain the presence or absence of melt | dissolution and completion | finish of melt | dissolution, the coloring agent was contained. Riboflavin was used as the coloring component. Therefore, the time until the dissolution of the carbonated spring tablet was measured according to the presence or absence of coloring and the color of the discharged water. Each is measured on 4 tablets, the one with the shortest time is displayed, and the other 3 are more than that.

The result of the shower discharge time using the carbonated spring tablet for the present invention and the thermography at the end of dissolution (body warming feeling: based on the same criteria as in Reference Example-1) are described below.
J5 7 minutes or more ○
J8 8 minutes or more ○
J10 10 minutes or more ◎

The results of shower discharge using a comparative carbonated spring tablet and thermography at the end of dissolution (body warming feeling: based on the same criteria as in Reference Example-1) are shown below.
J01 0.5 min or more ×
J05 2 minutes or more ×
J06 2 minutes or more ×

  According to the results of a questionnaire survey on shower time in March 1999 by the Institute for Bath Culture and Urban Life Research Institute, men took 6 minutes (0.10 hours) for one shower and women 7 minutes 12 seconds (0.12). Therefore, J5, J8, and J10 for the present invention correspond to the necessary shower time. Therefore, a single carbonated spring tablet can sufficiently handle one shower.

  On the other hand, it can be seen that in the comparative J01, J05, and J06, the carbonated spring tablet is completely dissolved during one shower, and the shower is performed without the carbon dioxide component. Therefore, it was found that it was necessary to add a new carbonated spring tablet for each shower.

[Experiment 2]
Using the same three types of carbonated spring tablets J5, J8, and J10 as used in Experimental Example 1, the manufacturing device 1 shown in FIG. 1 is changed to the manufacturing device 1 shown in FIG. 4, that is, the second microbubble generator 4 is changed. In the state where each of the tablets J5, J8, J10 is accommodated in the tablet accommodating portion 21 of the microbubble generating portion 2 of the producing device 1 shown in FIG. And the duration of carbon dioxide gas generation, that is, the time taken for the carbonated spring tablet to completely dissolve, was measured, and almost the same result as in Experimental Example 1 was obtained.

  However, according to the present experimental example 2, the microbubble mixed water discharged from the shower contains visually cloudy microbubbles, and when showered on an arm or the like, the shower presents a soft touch that clings together. It is water, and it can be expected to exert health promotion effects such as blood circulation promotion more effectively.
