Description

[Technical field]

[0001] The present invention relates to a carbonated fine bubble mixed water production device and a method for producing carbonated fine bubble mixed water. More specifically, the present invention relates to a carbonated fine bubble mixed water production device and a method for producing carbonated fine bubble mixed water that significantly improves the effects of carbonated spring bathing, such as promoting blood circulation, while also having a fine bubble effect, and furthermore, allows the amount of fine bubbles in the bath water to be freely changed. [Background technology]

[0002] Forming a mixture containing bicarbonate (sodium hydrogen carbonate or potassium hydrogen carbonate) and an organic acid into a foaming composition (solid material) by tableting or the like is applied to products such as detergents, bath additives, bath water cleaners, and pool disinfectants. These products (solid materials) have the advantage that when added to water, the components react to generate carbon dioxide gas and dissolve quickly, while at the same time providing consumers with a comfortable feeling when used, thereby increasing the product value. In particular, bath additives (sometimes called bath additives) actively utilize the blood circulation promoting effect of the generated carbon dioxide gas.

[0003] On the other hand, fine bubbles with a diameter of, for example, 0.05 mm or less, known as fine bubbles, are said to have a high cleaning ability and have been widely used in shower equipment, etc. In addition, when fine bubbles are generated in closed water areas such as lakes and aquaculture ponds, they have been used to promote the dissolution of oxygen in the water and the dissolution of gas in the water, among other effects.

[0004] Patent Document 1 discloses a technique for modifying shower equipment to change the amount of contact between tablets such as carbon dioxide gas generating agents and the water flow. This technique makes it possible to maintain the health-promoting effects of the tablets for a long period of time.

[0005] However, to utilize this technology, it is necessary to change the structure of the shower head, which is complex and expensive, and it is not easy to control the amount of carbonated fine bubbles.

[0006] The present inventors have also proposed the technologies described in Patent Documents 2 and 3 as technologies for providing comfortable shower water with enhanced health benefits by dissolving a carbon dioxide gas-generating component in hot water to generate carbon dioxide fine bubbles.

[0007] However, as a result of research, it was found that the ratio of hot water to fine carbonated bubbles in the carbonated fine bubble mixed water obtained by the technology of Patent Document 2 cannot be changed.

[0008] In the conventional technologies of Patent Documents 1 and 2, the mixing ratio of carbonated fine bubbles is always constant, so it was not possible to respond to detailed requests, such as increasing the amount of carbonated fine bubbles to remove sweat odor in summer when people sweat a lot, or to use carbonated fine bubble mixed water for as long as possible or to use it in as short a time as possible.

[0009] In addition, although the technology in Patent Document 3 was able to control the ratio of hot water and carbonated fine bubbles, there was a problem that the structure, which is attached to the outside, lacked stability. In other words, since it is possible to easily take a shower with carbonated fine bubble mixed water by attaching it to a shower head, it is an advantage that it can be easily set on the built-in shower head even when traveling, but on the other hand, it can be displaced or removed with the slightest touch or impact, which leads to cumbersomeness in places where it is assumed that it will be used many times, such as at home or in a beauty salon.

[0024] 13. A method for producing carbonated fine bubble mixed water as described in 11 above, characterized in that the fine bubbles penetrate deep into the skin, cleansing even the pores. Effect of the Invention

[0025] According to the inventions shown in 1 and 8 above, by varying the overlapping area of ​​the hole groups, it is possible to change the amount of bath additives that come into contact with and pass through, and therefore the amount of fine bubbles in the shower.

[0026] According to the inventions shown in 2, 3, 9 and 10 above, the overlapping area of ​​the hole groups can be quickly and easily adjusted to suit the user's preference.

[0027] According to the inventions shown in 4 and 11 above, whether the pore distributions of the holes provided in the first hole group plate and the second hole group plate are the same or different, simply moving either one of them can change the degree of overlap of the pores, thereby making it possible to vary the amount of running water and the amount of fine bubbles coming into contact with the tablet.

[0028] According to the inventions shown in 5 and 12 above, the pH of the hot water discharged from the hot water outlet is kept neutral, resulting in a large amount of bicarbonate ions being present in the water, which is expected to have a significant effect in promoting blood circulation and cleansing.

[0029] According to the invention shown in 7 above, the dissolution state of the carbonated bath agent contained in the tablet container can be easily and constantly monitored from the outside.

[0030] The present invention having the above configuration is a method for producing fine bubble mixed water that combines the effects of a carbonated spring bath with the effect of fine bubbles, and a production device for easily obtaining the fine bubble mixed water. By discharging (shower discharge) hot water mixed with carbon dioxide gas components and fine bubbles from the discharge port of the production device, it is possible to expect health promotion effects such as a cleansing effect and promotion of blood circulation.

[0031] Another use of the shower is to activate the internal organs by applying hot water to them. For example, if you have a stomach ache after eating greasy food, you can use a hot shower to activate your stomach and relieve the bloating. By using carbonated fine bubble water instead of regular shower water, you can more effectively activate your internal organs.

[0032] In particular, the present invention is configured to place the tablet storage unit on the hot and cold water path from the water supply hose to the shower head. Compared to a configuration in which the tablet storage unit is attached to the outside of the shower head, the tablet storage unit will not come off or shift out of position even if the shower head is hit due to carelessness by the user, etc. Therefore, it is a technology that makes it possible to continue to use carbonated fine bubble mixed water stably, without requiring excessive caution in handling, and that provides cleaning effects and health-promoting effects such as blood circulation promotion equal to or greater than those of showerheads with conventional carbonated bath additive storage units.

[0033] According to the inventor's research, the effect of the present invention is that, in the case of conventional showerheads having a carbonated bath additive storage section, the hot water that the carbonated bath additive comes into contact with is equivalent to running water from a tap, and is not fine bubble mixed water with air bubbles mixed in, whereas in the present invention, the hot water that the carbonated bath additive comes into contact with is fine bubble mixed water with air bubbles mixed in due to the two hole group plates, the first hole group plate provided in the first connection section and the second hole group plate provided in the tablet storage section, and the hot water that flows into the tablet storage section becomes fine bubble mixed water with air bubbles mixed in, and the carbonated bath additive is brought into contact with this fine bubble mixed water and dissolved, thereby obtaining carbonated fine bubble mixed water.

[0034] In the present invention, "hot water" refers to water, or warm or heated water, or a mixture of both. "Fine bubbles" refers to what are called fine bubbles. In the present invention, "amount" refers to "mass" unless otherwise specified, "%" refers to "mass%" unless otherwise specified, and "parts" refers to "parts by mass" unless otherwise specified.

FIG. [Diagram 5] FIG. 2 is a perspective view showing a second connection part that connects the tablet storage part and the shower head in the carbonated fine bubble mixed water manufacturing device according to the present invention.

[0036] Hereinafter, the carbonated fine bubble mixed water manufacturing device (hereinafter, sometimes simply referred to as the manufacturing device) and the carbonated fine bubble mixed water manufacturing method (hereinafter, sometimes simply referred to as the manufacturing method) according to the present invention will be described with reference to the drawings.

[0037] FIG. 1 shows an exploded perspective view of an embodiment of a production device 1 according to the present invention. The manufacturing device 1 is composed of a tablet storage section 3 which stores carbonated bath additive T therein, a first connection section 2 which connects the tablet storage section 3 to a water supply hose 5, and a second connection section 4 which connects the tablet storage section 3 to a shower head 6.

[0038] As shown in Figures 2 and 3, the first connection portion 2 is provided with a first hole group plate 21 having a number of fine holes 22 and a locking hook 23, and the tablet storage portion 3 is provided with a second hole group plate 31 having a number of fine holes 32, a storage portion 33 and a locking hole 34.

[0039] The locking hole 34 of the tablet storage section 3 is formed in an arc along the side wall of the cylindrical tablet storage section 3, and the locking hook 23 of the first connection part 2 is inserted into the lower opening 35 of the locking hole 34 of the tablet storage section 3 and the hook tip part 24 of the locking hook 23 protrudes from the upper opening 36 of the locking hole 34.As a result, the first connection part 2 and / or the tablet storage section 3 rotate in accordance with the locking hole 34, making it possible to displace the pore distribution of the first hole group plate 21 and the second hole group plate 31.

[0040] The holes 22 of the first hole group plate 21 and the holes 32 of the second hole group plate 31 as well as the locking hooks 23 and locking holes 34 may be arranged so that the holes can be positioned so as to be completely aligned or completely blocked by shifting the pore distribution, or so that it is impossible to position the holes so as to be completely aligned or completely blocked.

[0041] In FIG. 3(a), the locking hook 23 abuts against one end of the locking hole 34, and is positioned so that the pore distributions match, and in FIG. 3(b), the locking hook 23 abuts against the other end of the locking hole 34, and is positioned so that the pore distributions are different but not completely blocked.

[0042] Moreover, by adjusting the rotation position, it is possible to arrange the holes so that they overlap in different ways. When hot and cold water supplied from the water supply hose 5 flows through the numerous holes provided in the first hole group plate 21 and the second hole group plate 31, the water flow changes irregularly and fine bubbles are generated in the hot water. When the overlapping of the holes changes, the amount of fine bubbles in the hot water changes along with the amount of water passing through.

[0043] When the pores can be positioned so that they are completely aligned or completely blocked, it is preferable to arrange the locking holes 34 so that the pores are positioned so that they are completely aligned when the locking hook 23 abuts against one end of the locking hole 34, and the pores are positioned so that they are completely blocked when the locking hook 23 abuts against the other end of the locking hole 34. With this structure, no matter what position the pore distribution is in, the pores can be easily brought into a completely aligned or completely blocked state simply by rotating the first connection part 2 and / or the tablet accommodating part 3 until the locking hook 23 abuts against the locking hole 34 without the need for delicate observation or operation.

[0044] Fine bubbles are generated by the first hole group plate 21 and the second hole group plate 31 before the hot water supplied from the water supply hose 5 comes into contact with the carbonated bath additive T, the carbonated bath additive T is more easily dissolved by the fine bubbles, and the hot water is sprayed from the shower head 6 as water mixed with highly concentrated carbonated fine bubbles.

[0045] A known means is used for storing the carbonated bath agent T in the tablet storage section 3. In the embodiment shown in FIG. 1, the tablet storage section 3 and the second connection section 4 are connected by screwing so as to be easily removable. When using the manufacturing device according to the present invention, the tablet storage section 3 and the second connection section 4 are removed, the carbonated bath agent T is stored in the storage section 33 in the tablet storage section 3, and the tablet storage section 3 and the second connection section 4 are again connected by screwing, but this configuration is not limited to this. For example, the tablet storage section 3 and the second connection section 4 may be configured to be openable and closable while being partially connected by a hinge or the like, or a configuration may be adopted in which an opening and closing section large enough to pass the carbonated bath agent T is provided in a part of the tablet storage section 3, and the carbonated bath agent T is stored in the storage section 33 by opening the opening and closing section.

[0046] As another embodiment of the manufacturing device of the present invention, as shown in Figure 4, the first connection portion 2 and / or the tablet storage portion 3 may be configured to slide to displace the overlapping positions of the holes in the first hole group plate 21 and the second hole group plate 31.

[0047] In other words, by arranging the locking holes 34 of the tablet storage section 3 in a straight line, the first connection section 2 and / or the tablet storage section 3 slides in accordance with the locking holes 34, making it possible to displace the pore distribution of the pores 22 of the first hole group plate 21 and the pores 32 of the second hole group plate 31.

[0048] The pores 22 of the first connection portion 2 and the pores 32 of the tablet storage portion 3 as well as the locking hooks 23 and locking holes 34 may be arranged so that the pores can be positioned so that they are completely aligned or completely blocked by varying the pore distribution, or they may be arranged so that it is impossible for the pores to be positioned so that they are completely aligned or completely blocked.

[0049] In addition, by adjusting the slide position, it is possible to obtain shower baths with different overlapping of the pores. As the overlapping of the pores changes, the amount of water passing through also changes, and the amount of fine bubbles in the water also changes.

[0050] When the pores can be positioned so that they are completely aligned or completely blocked, it is preferable to arrange the locking holes 34 so that the pores are positioned so that they are completely aligned when the locking hook 23 abuts against one end of the locking hole 34, and the pores are positioned so that they are completely blocked when the locking hook 23 abuts against the other end of the locking hole 34. With this structure, no matter what position the pore distribution is in, the pores can be easily brought into a completely aligned or completely blocked state simply by rotating the first connection part 2 and / or the tablet accommodating part 3 until the locking hook 23 abuts against the locking hole 34 without the need for delicate observation or operation.

[0051] 5, a third hole group plate 41 may be provided in the second connection part 4. By providing another hole group plate downstream of the storage part 33, the generation of fine bubbles is further promoted, and the carbonated bath additive T can be prevented from clogging the hot water outlet hole 61 of the shower head 6 and causing poor hot water flow by dissolving small pieces of the carbonated bath additive T and washing them away.

[0052] The position where the third hole group plate 41 is installed may be between the storage section 33 in the tablet storage section 3 and the hot and cold water ejection holes 61 of the shower head 6, and does not have to be limited to the inside of the second connection section 4. Also, it does not have to be limited to the shape of a hole group plate, and for example, a mesh body may be arranged, or a mesh body may be arranged in addition to a hole group plate. Furthermore, a plurality of hole group plates and / or mesh bodies may be arranged.

[0053] According to this configuration, the carbonated fine bubbles generated in the tablet storage section 3 are further broken down into fine carbonated fine bubbles by passing through the hole group plate or net-like body arranged downstream, which further improves the blood circulation promoting effect, cleansing effect, etc. The degree of breakup can be appropriately set by the size of the pores of the hole group plate or the mesh of the net-like body, and the number of hole group plates or net-like bodies arranged.

[0054] In order to make it possible to easily grasp the dissolved state of the carbonated bath salts T contained in the storage section 33 from the outside at all times even during shower discharge, it is preferable to provide at least a part of the storage section 33 with a window section 37 made of a transparent material, and to configure the storage section 33 so that it can be visually observed through the window section 37 which is part of the transparent material.

[0055] The carbonated fine bubble mixed water discharged in the shower by the manufacturing device 1 having the above configuration preferably has a pH of 6.8 to 8.5 when discharged from the water outlet 61 of the shower head 6. With this configuration, the pH of the water discharged from the water outlet 61 is kept neutral, resulting in a large amount of bicarbonate ions being present in the water, which is expected to have a significant effect of promoting blood circulation and cleansing effects.

[0056] This shower bath with carbonated fine bubble mixed water continues until all of the carbonated bath agent T has been dissolved. Even if the shower bath is temporarily stopped, as long as the carbonated bath agent T remains in the storage section 33, the shower can be turned on again to obtain a shower bath with carbonated fine bubble mixed water.

[0057] The carbonated bath agent T of the present invention may be any solid, regardless of its composition. There are no particular limitations on its shape or size, and it may be in the form of tablets, spheres, granules other than cubic shapes, etc.

[0058] Carbonated bath additive T preferably used in the present invention includes, for example, the one previously proposed by the present inventor and described in Japanese Patent No. 6268332, and is exemplified below.

[0059] After granulating bicarbonate with polyethylene glycol (hereinafter sometimes referred to as "PEG"), an organic acid (such as citric acid, succinic acid, malic acid, fumaric acid, etc., with citric acid being the most preferable) is mixed with PEG or granulated, and then mixed under conditions within a certain ratio. The following excipients are added and tablets are formed by compression molding. The pH of the tablet immediately after dissolution is designed to be within the following range. When water penetrates the tablet, it reacts to effervescently generate carbon dioxide gas in a vigorous, uniform and continuous manner, and the carbon dioxide gas generated reacts with the tablet in a constant pH range. The bubbles can be generated over a long period of time as micro-sized fine carbon dioxide gas, and the tablet continues to produce micro-sized bubbles until it has completely dissolved. The pH of the water is designed to be 5.5 to 9.0 so that the bubbles are neutralized in the water before evaporating into the air, dissociating into bicarbonate ions and dissolving at a high concentration of bicarbonate ions, and the pH of the water is preferably 6.0 to 8.5, and particularly when the pH of the water ejected from the hot water outlet 61 is in the range of 6.8 to 8.5 as described above, the cleansing effect and health-promoting effects such as promoting blood circulation are maximized.

[0060] Furthermore, since the bicarbonate mixture is a granulated product prepared by coating with PEG using a fluidized bed, the effects of the present invention, such as a continuous and uniform reaction in the tablet, are greatly exhibited.

[0061] In addition, the tablet hardness is preferably 15 kg or more, more preferably 25 kg or more, and particularly preferably 30 kg or more, so that a continuous and stable reaction of the chlorine neutralizing compound can be obtained, and it is preferable that the tablet is molded to a high hardness so that the chlorine neutralization reaction inside the tablet can be suppressed and the dissolved part of the tablet can quickly remove chlorine in hot water. The higher the chlorine removal effect, the greater the health benefits, such as improved blood circulation and increased body temperature, even when taking a shower.

[0062] Furthermore, the tablet friability is preferably 10.0 wt% or less, more preferably 5.0 wt% or less, and even more preferably 3.0 wt% or less, so that the chlorine neutralizing compound can continue to react stably and the efficiency of the chlorine neutralization reaction inside the tablet can be maximized, and health-promoting effects such as improved blood circulation and increased body temperature can be achieved even when taking a shower.

[0063] For the compression molding to prepare the tablets of carbonated bath agent T preferably used in the present invention, a known compression molding machine can be used without any particular restrictions, for example, a hydraulic press, a single shot tablet press, a rotary tablet press, a briquetting machine, etc. can be used. The size of the punch used in this tablet press, etc., is preferably 7 mm or more in diameter when the punch is circular, and preferably 7 mm or more in diameter when the punch is triangular or rectangular. The same applies to the thickness of the punch. When obtaining a circular tablet product, the diameter of the tablet is preferably 7 mm or more, more preferably 10 mm or more, and the thickness is also 7 mm or more, preferably 10 mm or more, and when a triangular or rectangular tablet is obtained, the diameter and thickness are each preferably 7 mm or more, particularly 10 mm or more, when converted to a circular tablet.

[0064] It is preferable to slowly generate micro-sized bubbles in tablets having the above-mentioned hardness and friability and of a certain size or larger, and to more efficiently dissolve carbon dioxide in the bath water; therefore, the hardness is 15 kg or more, desirably 25 kg or more, and particularly preferably 35 kg or more, the friability is 10.0 wt% or less, preferably 5 wt% or less, and particularly preferably 3 wt% or less, and the diameter and thickness are particularly preferably 10 mm or more, so that the generation of carbon dioxide in the tablet occurs more effectively, the dissolution of carbon dioxide in the water is efficient, and the diameter of the bubbles becomes fine, making this carbonated bath additive T preferable for use in the present invention.

[0065] After the water is delivered to the shower head 6 by the water producing device 1 having the above-mentioned configuration, the carbonated fine bubble mixed water discharged from the water outlet 61 of the shower head 6 preferably has a pH of 6.8 to 8.5. With this configuration, the pH of the water discharged from the water outlet 61 is kept neutral, resulting in a large amount of bicarbonate ions in the water, which is expected to have a significant effect of promoting blood circulation and cleansing.

[0066] The shower head 6 to which the manufacturing device 1 and manufacturing method of the present invention are applied may be any known type, and generally has a configuration including a water supply hose 5 to which hot and cold water is supplied, a handle to which the water supply hose 5 is connected, and a head portion that is integral with the handle portion and has hot and cold water outlets 61. The handle portion and the head portion may be integral, or may be formed separately and connected or joined to be integral, or the head portion may be directly or indirectly connected to the handle portion so that the direction or angle of the head portion can be changed, or the shower head may have various water outlet modes so that the desired water outlet mode can be selected according to the mood or situation, or may have a configuration including at least a head portion having hot and cold water outlets 61, that is, an existing general shower head 2 having various configurations with different types, shapes, sizes, etc. can be used. In other words, a shower head that is used on a daily basis, or an existing shower head installed in a hotel or sports gym at a travel destination can be used.

[0067] The water supply hose 5 and showerhead 6 to which the production device 1 of the present invention is connected are screwed together by a connection part of the showerhead 6, which generally has a male thread configuration, and a connection part of the water supply hose 5, which generally has a female thread configuration, and this screwed connection is removed and connected with the production device 1 of the present invention interposed between them.

[0068] Therefore, although not shown, the first connection part 2 of the production device 1 has a male thread configuration that can be screwed into a female thread configuration provided on the water supply hose 5 for connection to the shower head 6, and is screwed into and connected to the water supply hose 5 by this male thread configuration. The second connection part 4 has a female thread configuration that can be screwed into a male thread configuration provided on the shower head 6 for connection to the water supply hose 5, and is screwed into and connected to the shower head 6 by this female thread configuration.

[0069] Furthermore, when connecting the production device 1 of the present invention to the connection part between an existing water supply hose 5 and shower head 6, if it is not possible to screw them together due to differences in thread diameter, thread pitch, etc., or if the water supply hose 5 and shower head 6 are not screwed together in the first place, an adjustment connection part can be used between the connection part between the water supply hose 5 and shower head 6 and the production device 1 of the present invention.

[0070] According to the manufacturing device 1 and manufacturing method of the present invention having the above-mentioned configuration, by connecting the manufacturing device 1 between the water supply hose 5 and the shower head 6, i.e., by arranging it upstream of the shower head 6, it is possible to add the carbonated fine bubble generation effect just upstream of the shower head 6 without affecting the shower spray shape and water discharge volume of the shower head 6 in use, or, in the case of a shower head 6 equipped with various water discharge modes, without affecting each water discharge mode.

[0071] Furthermore, these effects are not limited to shower heads 6 that are used on a daily basis, but can also be applied to existing shower heads 6 installed in hotels, sports gyms, and other locations when traveling.

[0072] Furthermore, the carbonated bath additive T used in the present invention does not necessarily have to be circular with a flat surface, and there is no restriction on its shape, as it may be oval, tablet-like, or spherical; however, if it is circular with a flat surface, it is preferable that the diameter and thickness are 10 mm or more, or if it has another shape, it is preferable that it is a solid body having a size of 10 mm or more.

[0073] Furthermore, when carbonated bath additive T is circular with a flat surface and has a diameter and thickness of 10 mm, it is preferable that the storage section 33 for storing the carbonated bath additive T in the present invention has a volume sufficient to allow the carbonated bath additive T to move freely, including rotating.

[0074] According to this configuration, the carbonated bath additive T not only sways and moves with the hot water inside the storage section 33, but also rotates, so that it comes into contact with the hot water over a wide area and in various directions and dissolves, which is expected to significantly increase the fine bubble generation effect. The health promotion effect and cleaning effect, etc. are also significantly improved.

[0075] Compared to Utility Model Registration No. 3187368 previously proposed by the present inventor, the present invention allows the amount of fine bubbles in carbonated fine bubble mixed water to be changed as desired, making it possible to easily adjust the amount of fine bubbles according to the season or circumstances of the day; in addition, the supplied hot and cold water generates fine bubbles by the first hole group plate 21 and the second hole group plate 31 before coming into contact with the carbonated bath additives T, making it possible to dissolve the carbonated bath additives T more efficiently, and making it possible to take a shower with a higher concentration of carbonated fine bubble mixed water. Also, compared to Patent Application No. 2022-186252, it is possible to take a stable shower with carbonated fine bubble mixed water without having to be overly careful in handling.
