The specific embodiment
Below, for one embodiment of the invention, Yi Bian with reference to accompanying drawing, explain on one side.
Embodiment 1
Fig. 1 is the figure of summary of the structure of the carbonate spring generating apparatus 10 of explanation in one embodiment of the invention.As shown in Figure 1, the carbonate spring generating apparatus 10 of the present embodiment has: for gas bubble stream 12 that carbon dioxide bubble is dissolved in the water with for by the carbon dioxide generating unit 20 of carbon dioxide bubble injected water and bubble injection unit 30.
Particularly, the water for example injecting from the water injection pipe portion 40 being connected with water channel, the selection portion 48 as triple valve by following, optionally circulate in the either party of the 1st supply unit 42 and the 2nd supply unit 44 or be truncated.In the situation of water flowing in the 1st supply unit 42, and as the tablet (tablet) 24 of raw material, react and produce carbon dioxide in following carbon dioxide generating unit 20.The carbon dioxide having produced former state with bubble form, sneaked under the state in water, by the generation switching part 46 as triple valve, circulate in gas bubble stream 12.
Wherein, gas bubble stream 12 is for by following carbon dioxide generating unit 20 or bubble injection unit 30 and the current of injecting carbon dioxide bubble are logical, the stream that this carbon dioxide bubble is dissolved in the water thus.That is, carbon dioxide bubble is by Plug Flow(plug flow) mode (cast reactive mode) dissolving.In gas bubble stream 12, the effective diameter of gas bubble stream 12 is determined, so that the viscous drag of the carbon dioxide bubble in this water under the flow velocity of the mobile water of this gas bubble stream 12, become the situation that the carbon dioxide bubble in this gas bubble stream 12 is maximum diameter, more than being the buoyancy of this carbon dioxide bubble in the situation of effective diameter of this gas bubble stream 12.Like this, can prevent the flowing instability at the interior carbon dioxide bubble delay of gas bubble stream 12 and carbon dioxide bubble.This result, carbon dioxide can be dissolved in water well, obtains needing the carbonate spring of concentration.Moreover, below show as in the situation of water, except as otherwise noted, comprise the water that is injected with carbon dioxide bubble.
Particularly, according to Archimedes principle, buoyancy F draws according to following formula (1).

At this, D
bfor the maximum [m] of bubble diameter, the density [kg/m that ρ is water

On the other hand, if consider at the flow of the mobile water of gas bubble stream 12 etc., the water that circulates in gas bubble stream 12 is turbulent flow, its viscous drag R draws as shown in the formula (2) like that as the approximate expression obtaining according to experiment value.

[several 3]
Re is dimensionless number Reynolds number, Re=Dv ρ/μ,
D is the effective diameter [m] of gas bubble stream 12, the flow velocity that v is water [m/s], the viscosity that μ is water [Pas].
At this, the diameter of carbon dioxide bubble is maximum, is buoyancy F and viscous drag R balance in the situation of effective diameter of gas bubble stream 12, for
[several 4]
By its arrangement, for
[several 5]
Flow velocity v be flow H divided by the value of cross section (the passing through area) gained of gas bubble stream 12, for
[several 6]
Therefore using above-mentioned (4) formula as flow H and bubble diameter D
brelation decomposing solve and can draw relation as shown in Figure 2.From the relation obtaining in this wise, the flow H[m based on carbonate spring generating apparatus 10 needed water
3/ s], the effective diameter D[m of gas bubble stream 12] diameter D based on carbon dioxide bubble
bmaximum set.Particularly, to become the mode in the region more than curve in Fig. 2, set the effective diameter of gas bubble stream 12.In the example of Fig. 2, known water for example in the mode of flow H=10L/ minute 12 circulation of gas bubble stream in the situation that, the effective diameter D of gas bubble stream 12 is about below 16.5mm.
Moreover, in the present embodiment, the effective diameter of pipe, the cross section that refers to pipe is corresponding to this diameter of a circle, in the situation that the shape beyond this, corresponding to the concept of the equal circular diameter of sectional area in circular situation.
On the other hand, in the present embodiment, carbon dioxide bubble in injected water dissolves by Plug Flow mode, therefore the length of gas bubble stream 12 is determined, so that the water that is injected with carbon dioxide bubble in the time (passing through the time) of gas bubble stream 12 circulations, becomes the concentration of ordinary dissolution of (desired) carbon dioxide in order to obtain stipulating more than the required time.At this, above-mentioned by time T [s] as the length L [m] of gas bubble stream 12 and the relation of the flow velocity v of mobile water therein, for
[several 7]
It is solved for L, for
[several 8]
Therefore, exist gas bubble stream 12 thinner, i.e. the length L of the less gas bubble of the effective diameter D stream 12 of gas bubble stream 12 relation of more growing of just having to.Particularly, according to the present application person's experiment, at flow H=8L/ minute, in the situation that the effective diameter D of gas bubble stream 12 is 12mm, for example for obtain as the carbonate spring of the 1000ppm of the gas concentration lwevel of expectation by time T, be about 4 seconds, so the length L of gas bubble stream 12 need to be more than about 5m.Moreover water is used as the concept that comprises water and hot water in this description.In addition, carbonate spring is used as the concept that extensively comprises the water that is dissolved with carbon dioxide, is not limited to for example to require the carbonate spring of the spa code regulation of gas concentration lwevel more than 250ppm.Moreover, in the situation that flowing of the water in gas bubble stream 12 can be seen complete turbulent flow as, the resistance coefficient C of bubble
dalso can replace using above-mentioned (3) formula and be approximately C
d=0.44.
In gas bubble stream 12, be provided with at least one restriction 14, the effective diameter of restriction 14 is less than the effective diameter of gas bubble stream 12 that restriction 14 is not set.Fig. 3 is the length direction of the gas bubble stream 12 that contains a restriction 14, i.e. axial sectional view.
When water passes through restriction 14 as shown in Figure 3, the carbon dioxide bubble injecting in this water is by grain refined.Therefore,, due to the contact area increase of carbon dioxide bubble and water, can expect that dissolution time shortens.According to inventor's experiment, learn at the effective diameter d that there is no the part of restriction 14
12in gas bubble stream 12 for 12mm, 5 effective diameter d have been configured
14after restriction 14 for 8mm, be the gas bubble stream 12 below 1.5m, just can realize with there is no the situation of restriction 14 under need the concentration of ordinary dissolution of the carbon dioxide that the gas bubble stream 12 of 5m is identical.That is,, by restriction 14 is set in gas bubble stream 12, can shorten the length of gas bubble stream 12.The length of this gas bubble stream 12 is designed, so that in the logical situation of carbon dioxide and current, can only spend carbon dioxide solubilized until the time of the desired gas concentration lwevel of carbonate spring generating passes through at gas bubble stream 12.
At this, by the effective diameter d of gas bubble stream 12
12be made as 12mm, the flow H of the water in 12 circulations of gas bubble stream is made as to 8L/ minute, repeatedly change the effective diameter d of restriction 14
14size, calculating gas bubble stream 12 does not have the part of restriction and the pressure differential of restriction 14, obtains relation as shown in Figure 4.Like this, minimum according to the difference of the big or small pressure differential of the effective diameter of restriction 14.Therefore, can think that the carbon dioxide bubble in water carries out grain refined, be not by restriction 14 with there is no the pressure differential of the part of restriction, but caused by speed difference.
The downstream than above-mentioned restriction 14 at gas bubble stream 12, is provided with pressure retaining parts 16.This pressure retaining parts 16 is openings of path or slit-shaped for example, in order to prevent due to the terminal part of gas bubble stream 12 opening significantly, thereby atmosphere enters to inside from the terminal part of gas bubble stream 12, the pressure drop in pipe to atmospheric pressure arranges.Thus, the pressure of the water in gas bubble stream 12 is maintained.
In addition, it is among this restriction 14 that expectation does one's utmost to shorten restriction 14(in the situation that a plurality of restriction 14 is set, be arranged on gas bubble stream 12 downstream, be the restriction 14 of pressure retaining parts 16 sides.Hereinafter referred to as final restriction 14.) and as the distance of shower head 18 of the 1st discharge opening of the carbonate spring that spues.Particularly; even be preferably made as by final restriction 14, by the carbon dioxide bubble of grain refined residue, dissolved in residual situation; from this final restriction 14 to dissolving residual bubble the stream of shower head 18, can partly not be detained yet, but keep the distance that spued from shower head 18 by the state of grain refined.Like this, can preventing from this final restriction 14 to the stream of shower head 18, dissolve residual bubble and be detained formation air pocket, this air pocket is by plug-flow once and by shower head 18, send bubble bubble sound, or mobile such situation that user does not feel soon that gives that gets clogged of water.This is in the situation that the hole of the carbonate spring that spues as shower head 18 is little effective especially.
The openings of sizes of the path in this pressure retaining parts 16, for example, can calculate approx from Bernoulli's theorem.Below an example of the calculation method of the effective diameter of pressure retaining parts 16 is described.Moreover, effective diameter and be man-to-man relation by area, determine either party the opposing party by unique decision, therefore as basic synonym things, describe in this manual.
Fig. 5 be pattern the present embodiment is described the figure of the mode of carbonate spring generating apparatus 10 while being connected with water-supply line.Water pipe 82 is by water main 80 branches.In addition, water pipe 82 is connected via the not shown fire hose is first-class with carbonate spring generating apparatus 10.That is, in the mode of Fig. 5, the hydraulic pressure by water pipe 82 to carbonate spring generating apparatus 10 for feedwater.Moreover, though do not represent in Fig. 5, also can between water pipe 82 and carbonate spring generating apparatus 10, water heater be set, to carbonate spring generating apparatus 10 supplying hot waters.
In such mode, the loss of the stream of water pipe 82 and/or not shown water heater etc. can not be ignored.Therefore, even the situation of the Bernoulli's theorem of the relation of applicable expression throttling and flow also needs to consider that friction loss is viscous drag.Moreover for the restriction 14 of carbonate spring generating apparatus 10, the thickness on the circulating direction of water as thin as a wafer, therefore can be ignored loss.Generally considered the Bernoulli's theorem (expansion Bernoulli's theorem) of friction loss, on certain point, the density of fluid is ρ, and flow velocity is v[m/s], pressure is P[Pa], be highly z[m] time, meet
[several 9]
Yet, if usually above-mentioned Reynolds is counted Re it is flowed for laminar flow to hundreds of scopes tens of, more than 1000 be turbulent flow on the contrary.In the carbonate spring generating apparatus 10 of the present embodiment, if this flow is considered pipe arrangement footpath etc., Reynolds is counted Re and is surpassed 10000, so the flowing for turbulent flow of its inside.Friction loss in turbulent flow (for example in the example of Fig. 5, B1, B2), the formula (7) below that can obtain according to experimentally is calculated.

[several 11]
(9) in formula the right the 1st, be commonly referred to as dynamic pressure item.Fig. 6 represents the figure of the relation of this flowing pressure and flow L for the different water pipe 82 of diameter.As judged from Fig. 6, even if flow is 30L/ minute, for example, be that pipe arrangement footpath (diameter) is the pipe of 12mm, the value of dynamic pressure item mostly is 0.01MPa most.On the other hand, hydrostatic pressure is got for example such value of 0.2MPa, and therefore in (9) formula, dynamic pressure item can be ignored.Moreover, in " Give water device Standard Quasi Meter draws construction method 2.3 Let Meter and makes water consumption Decision fixed (decisions of water supply installation standard plan construction method 2.3 design Water usages) " of MHLW's water supply installation database; the water yield that shower is shown is 8～15L/ minute; above-mentioned flow 30L/ minute corresponding to being far longer than this value; in the situation that having supposed to use shower, far away higher than the situation of supposing the water yield.

For example, in the above-described embodiment, be provided with for by the carbon dioxide generating unit 20 of carbon dioxide bubble injected water and bubble injection unit 30 both, but not necessarily must both, as long as possess any one and above-mentioned gas bubble stream 12, can bring into play and can not need to pressurize and carry out the generation of carbonate spring by pump etc., and the effect of the present invention that carbonate spring generating means 10 can miniaturization.
In the above-described embodiment, gas bubble stream 12 is set as flexual pipe, but is not limited to this.It is also harmless that gas bubble stream 12 is made as the effigurate pipe arrangement of tool.In this situation, gas bubble stream 12 also can be arranged in the framework of carbonate spring generating apparatus 10.In addition, flexual pipe important document not necessarily in the situation that gas bubble stream 12 is made as the effigurate pipe arrangement of this tool.And, exemplified with shower head, being arranged on the 1st portion 18 that spues, but being not limited thereto, shower head is important document not necessarily.
In the above-described embodiment, in gas bubble stream 12, be provided with a plurality of restriction 14 but be not limited to this.The effect that at least one restriction 14 can produce the application is set in gas bubble stream 12.
In the above-described embodiment, exemplified with the opening that is shaped as circle, slit-shaped of pressure retaining parts 16, but be not limited to such shape.As long as meet the condition that atmosphere do not enter gas bubble stream 12, just not limit shape.
In addition in the above-described embodiment, from generating switching part 46, to the 1st, spuing the stream of portion 18 and be provided with water flow generator 56, LED58, but these important documents not necessarily, even situation about not arranging also can obtain effect of the present invention.
In addition in the above-described embodiment, export department 26 is arranged on the height of regulation, but is not limited thereto as shown in Fig. 1, Fig. 7 etc.For example, also can adopt the method for any opening among the export department that optionally makes to be arranged on a plurality of height to change its height.
In addition in the above-described embodiment, injection unit 37 is arranged on selection portion 48 and generates on the pipe arrangement between switching part 46, but is not limited to this.Before from the 2nd supply unit 44 to gas bubble stream 12, can produce same effect.
In addition, in the above-described embodiment, pressure retaining parts 16 is clamped and is installed by O type ring 72,74 between the end of gas bubble stream 12 and shower head 18, but is not limited to this, so long as prevent that the parts that leak or flow into from outside air of carbonate spring are just not limited to O type ring.
In addition, in the above-described embodiment, pressure retaining parts 16, by installing from one that selects among the different a plurality of pressure retaining parts 16 of effective diameter, can change it by area, but be not limited to such mode.Particularly for example, as pressure retaining parts, it is that valve that effective diameter can change continuously also can be used as pressure retaining parts and is set up by area.
In addition, in the above-described embodiment, the effective diameter (passing through area) that changes pressure retaining parts 16 on the basis of water yield H that flows into carbonate spring generating apparatus 10 to be to meet above-mentioned important document A and B, but is not limited to such mode.For example, also can replace the effective diameter of pressure retaining parts 16 or outside this, set the amount of the carbon dioxide bubble producing by carbon dioxide generating unit 20 or bubble injection unit 30, to meet above-mentioned important document A and B.Like this, with the above embodiments similarly, with respect to the water of above-mentioned flow, can not reduce as far as possible thoroughly and dissolve and the carbon dioxide bubble of waste, can be met on the other hand the carbonic acid of carbonate spring generating apparatus 10 desired gas concentration lwevels.
Moreover, although do not mention for water temperature in the above embodiments, but the design that the temperature of the water that also can consider the temperature of the carbonate spring that generates or supply with to carbonate spring generating apparatus 10 changes carbonate spring generating apparatus 10, the specifically injection rate of the length of gas bubble stream 12 and/or the carbon dioxide that undertaken by carbon dioxide generating unit 20, bubble injection unit 30 etc.That is, because carbon dioxide bubble is the more high more indissoluble of water temperature solution, therefore can the more high length of gas bubble stream 12 or the amount of carbon dioxide that minimizing is produced by carbon dioxide generating unit 20, bubble injection unit 30 of more increasing of water temperature.Like this, even the high situation of water temperature also can be guaranteed the gas concentration lwevel in carbonate spring, or can not reduce the carbon dioxide that does not thoroughly dissolve and waste.
In the above embodiments, the example of the situation that is 1000ppm for the gas concentration lwevel of carbonate spring generating apparatus 10 desired carbonate springs is illustrated, but is not limited thereto.The carbonate spring concentration that is usually used for bathing use is more high better, therefore also can generate the roughly carbonate spring of saturated concentration of gas concentration lwevel.At this, roughly saturated concentration (roughly saturated concentration), refers to the concentration that can regard the concentration that almost reaches capacity as, for example, be confirmed as 95% degree of saturated concentration above, can be also the concept that comprises saturated concentration.Near saturated concentration, dissolution velocity obviously declines, therefore improve concentration till compare and need the considerable time with this concentration of arrival more than that, on the other hand if can regard the concentration that roughly arrives above-mentioned saturated concentration as, can obtain the effect of the situation based on saturated concentration, be therefore the concentration of considering these settings.In this situation, different according to the meltage of the water temperature carbon dioxide of the water of supplying with to carbonate spring generating apparatus 10 as mentioned above, therefore can consider that this factor carries out the design of carbonate spring generating apparatus 10.
