The present invention relates to carbonated water production unit and have its water purifier.In more detail, relating to can be correctly and promptly control the carbonate concentration of carbonated water, thereby provided rapidly the carbonated water of suitable carbonate concentration or taste salubrious, the drinking water sense of swallowing, that improved mouthfeel is arranged, and good, the cheap carbonated water production unit of simple structure, maintainability and have its water purifier easy to use.

Again, the present invention relates to be used to make unboiled water such as running water, particularly relate to the seat formula water purifier any place, easy to use that the position (the supply position of water purification) that can make sparge pipe (applying nozzle) moves to horizontal direction and vertical direction by the seat formula water purifier that the water purification mechanism (water purification element) that is made of adsorption elements such as filter elements such as ceramic filter or hollow line filter and active carbon etc. obtains water purification.

Background technology

Carbonated water is used to be provided to various soda dispensers as the carbonic acid source of various sodas.Also know in home-use drinking water and to give salubrious taste, to swallow sense, and improve the mouthfeel of drinking water by dissolving in ormal weight carbonic acid gas (for example carbonate concentration of 3～30ppm).

As the device of making such carbonated water, as various soda dispensers, proposed for example device to be designed to the in-line arrangement carbonator and constituted, the carbonic acid gas that makes the low temperature drinking water of pumping, provides with the carbonic acid gas cylinder direct gas-liquid mixed in pipeline, and become the method (spy opens the 2000-348250 communique) of carbonated water.Again, add water making device as home-use carbonic acid gas, propose for example the water flow passage portion and the discharge control part of configuration hydraulic pressure reaction equation air supply valve on the runner of water, or on the runner of carbonic acid gas, disposed the scheme (spy opens flat 9-253664 communique) of pressure-reducing valve, carbonic acid gas flow-control portion and hydraulic pressure reaction equation air supply valve etc.

But, above-mentioned any carbonated water production unit, because all the structure by complexity constitutes, so the setting of the carbonic acid gas scale of construction of supplying with and control difficulty, as one wishes not to the utmost aspect reliability in the setting of carbonate concentration and the rapid property, again because the integral body that device constitutes also scale is big and become complicated, so exist have to high price problem.Again, the problem that has the replacing difficulty of the parts that easily pollute (for example, the component parts of mixed carbonic acid gas and the portion of mixing of water).And water purifier is when for example being used for home-use water purifier, because be the formation that can not change the value of carbonic acid gas concentration, so not only can not set carbonic acid gas concentration according to user's hobby, and the difficulties such as affirmation of action, thereby there is inconvenient problem with use.

The present invention, be to propose in view of the above-mentioned problems, first purpose is to provide: can be correctly and promptly control the carbonate concentration of carbonated water, thereby provided rapidly corresponding user's carbonated water of hobby or taste salubrious, the drinking water sense of swallowing, that improved mouthfeel is arranged, and good, the cheap carbonated water production unit of simple structure, maintainability and have its water purifier easy to use.

On the other hand, in the water purifier of on present market, selling, roughly be divided into the product of seat formula that water purification mechanism is installed in the product of the form on the tap of water pipe and is placed on the position of leaving water tap.

Be installed in the water purifier of the form on the tap of water pipe, because be the water purifier main body is directly installed on the tap of water pipe, and the water purifier main body is adorned the filter cylinder of water purification mechanism and is used to switch the state that directly flows through running water and the switch cock that sprays the state of water purification in having, so on the intensity of the tap of water pipe and the convenience of operation, limited the size of the filter cylinder of interior dress water purification mechanism, therefore the water purification ability is little, mainly is that family uses.

Relative with it, the product of seat formula, though must being set, switch cock is used to switch state that directly flows through running water and the state that sprays water purification, but because can be by water purification machine body design is become large-scale form and suitably improves the water purification ability, so can be used on the family or commercial the using of using a large amount of water purification.

And, in the water purifier of this formula, there is the water purification of the acquisition of making to return the tap of water pipe and is installed in water purifier from one's body and from the form of this sparge pipe ejection water purification, thereby suitably select to use according to user's hobby in the form of this position ejection water purification with sparge pipe.

Particularly, on the seat formula water purifier of sparge pipe,,, be that center of rotation is rotated in horizontal plane with the one end therefore for the direction of the supply that changes water purification will make sparge pipe self so can not move simply because water purifier self is very heavy with latter.For example the spy to open the described form of flat 11-47731 communique be exactly the one example.Below, with reference to Figure 13 and Figure 14 this well-known seat formula water purifier is described.

Aforementioned spy drives the described seat of flat 11-47731 communique formula water purifier 200, by the runner switch 204 on the tap 202 that directly is connected water pipe etc., purify the water purifier main body 206 of unboiled water, connect runner switch and water purifier main body and the lead flexible pipe 208 of water purifier main body of unboiled water constituted communicatively, 204 its unboiled water imports of runner switch are connected on the tap 202 by nut 210.

Runner switch 204, the lower end water out of making a living, the rear end is a water transport port, on this water transport port, connect aforementioned flexible pipe 208, and, take in not shown flow channel switching valve in the inside of runner switch 204, utilize the control lever 212 operation flow channel switching valves of the sidepiece that is arranged on runner switch 204, will export state of emitting and the state of leading water purifier main body 206 from the unboiled water of tap 202 from unboiled water by flexible pipe 208 thereby switch directly.

Water purifier main body 206 as shown in figure 14, constitutes housing 214, upper end open, the fastening discoid base plate 222 in the lower end by loam cake 218, sparge pipes 220 in the housing 214 that the round-ended cylinder shape is arranged, supporting filter device unit 216 and the embedding housing 214.And, in lower center portion, be provided with an end of the L shaped water inlet nozzle 224 of flowing water passage, be installed on the ambut 226 that forms on the bottom of housing 214 waterproof state, and utilize base plate 222 supportings rotationally, on the water inlet 228 that is provided with on the other end of this water inlet nozzle 224, connect flexible pipe 208 communicatively.

Loam cake 218 is installed filter unit 216 in its lower end by filter support plate 230, and is installed in removably on the housing 214.Filter support plate 230, have from upper end central portion radius vector to the L shaped flowing water mouth 232 of deriving, and have protuberance 234, on the inner peripheral surface of this protuberance 234, link the upper end delivery port 236 of filter unit 216 removably at the tubular of the weak point of lower center portion opening.Again, the lower end water inlet 238 of filter unit 216 is attached on the outer peripheral face of water nozzle 224 into removably.

And, end with L shaped binding nozzle 240 of water purification passage, prominent upward the establishing of semicircular peristome 242 that forms from the upper periphery face of loam cake 218, and, the other end of this binding nozzle 240 is attached at the flowing water mouth 232 of aforementioned filter support plate, again, and from the peristome 242 prominent binding nozzles of establishing 240, a part is stretched out the loam cake medial surface, and other parts are stretched out the loam cake lateral surface.

And the base end part of L shaped sparge pipe 220 is attached at the derivation end that links nozzle 240, and the central shaft a that sparge pipe 220 is supported to link nozzle 240 is that turning cylinder can rotate in horizontal plane, and the front end of sparge pipe 220 is crooked downwards.

Therefore, on this water purifier main body 206, because the front end of sparge pipe 220 can axle a be that turning cylinder rotates in the predetermined angular scope in horizontal plane, so can change the supply position of water purification on a large scale at the height at the front end place of sparge pipe 220, but because this sparge pipe 220 rotates as center of rotation the one end in vertical plane, so when in the high container in the supply position of water purification (highly), providing water purification, often supply with difficulty, otherwise when highly low container provides water purification, if container is placed on the floor then may dabbles towards periphery, so must use the hand supporting container always, and, exist during the supply stop water purification when sparge pipe 220 is rotated in horizontal plane, residual water purification may drip from sparge pipe 220 front ends in the sparge pipe 220, and make problem such as immersion on every side.

The problem that present inventors exist for the water purifier main body that solves above-mentioned conventional example and the result that furthers investigate, if adopting and making sparge pipe self is the formation that center of rotation is rotated in vertical plane with the one end, even find that then rotating sparge pipe during stopping the water purification supply can not occur leaking yet, if but sparge pipe self not only can be rotated in vertical plane but also in horizontal plane, its rotating mechanism then, become so-called multi-joint structure, become complicated because constitute, so this part leak may increase and be difficult to be standing in the position of hope the sparge pipe front end etc. because these are former thereby be difficult to adopt.

In addition, on desk-top vacuum flask or electric kettle etc., though well-known formation is can its central shaft to be that turning cylinder rotates in horizontal plane and makes the hot water nozzle freely rotate 360 degree in horizontal plane by making main body, but these formations, when externally going up without any connection, or the thing that is connected with the outside is that electric wire is when having the thing of flexibility like that, because electric wire can move along with electric kettle, so can be suitable for, if but the product that the water supply hose with rigidity has been installed on the water purifier main body is used, then owing to be rotation in the horizontal plane of turning cylinder with the central shaft along with the water purifier main body, water supply hose also moves and article around running into, or because the rigidity of water supply hose, and make the water purifier main body of rotation get back to original position, so, be difficult to use in the same old way.In addition, it is circular that the section shape that above-mentioned desk-top vacuum flask or electric kettle etc. are cut open with horizontal plane is actually, but for section shape is oblong seat formula water purifier, owing to be difficult to specific (supposition) reasons such as central shaft, in horizontal plane, rotate such trial and we can say fully and can't carry out as turning cylinder.

Therefore, present inventors repeat various result of experiment, are to have found following method and finished the present invention.Promptly, because the slewing area on the present formula water purifier on the actual necessary horizontal plane, to compare very narrow and small scope just enough with the slewing area that adopts on well-known desk-top vacuum flask and even the electric kettle, so, if can adopt the past not adopt in the present formula water purifier, make the water purifier body in horizontal plane, only rotate the formation of predetermined angular, even then for example water supply hose moves and also can reduce it and move, so by adopting sparge pipe self formation free to rotate in vertical plane, the position of sparge pipe is moved in vertical direction and horizontal direction, and can be fixed on the position of hope easily.

Promptly, the present invention, second purpose provides following seat formula water purifier: the section shape of cutting open on horizontal plane is oblong, and installed on the seat formula water purifier of water supply hose with rigidity, even under the situation that water supply hose has moved when the water purifier main body is rotated in horizontal plane, by usually necessary this water supply hose of slewing area inner control mobile constant greatly, thereby the position (the supply position of water purification) of the front end of sparge pipe not only can in the horizontal direction but also can be moved to vertical direction, and constitute the seat formula water purifier easy to use that may also reduce simple and that drip.

In addition, the section shape that the what is called among the present invention is cut open with horizontal plane is " Long Circle ", not necessarily means it is oval, and the section shape of cutting open with horizontal plane also can be to make rectangular angle become the shape (racing track shape) of circle.

Again, the present invention, thus the 3rd purpose provides the seat formula water purifier that achieves the above object and can add the carbonic acid gas addition type of carbonic acid gas acquisition taste carbonated water salubrious, that the sense of swallowing is arranged in water purification.

At this moment, preferably water B flows into carbonated water production unit 10a from the side, via angle of bend is that the crooked water flow passage of 45～135 degree imports the formation near the applying nozzle 46 (with reference to Fig. 4) of below, angle of bend is the crooked forms of 90 degree, because the connection of pipe arrangement design easily, so better (shown in Figure 2 is that angle of bend is the situation of 90 degree).As carbonic acid gas supply unit 1, can constitute equally with the form of form of implementation shown in Figure 1.Again, the shape that the rectangular section shape of the water flow passage 21a of water B or the front end of its front end are thin etc. also can constitute equally with form of implementation shown in Figure 1.

In this example, when the supply of water B stopped, the water B of the inside of water flow passage 21a utilized gravity to discharge the state that can avoid carbonic acid gas supply unit 1 often to be got wet by water to the applying nozzle side.

By such formation, the same during with form of implementation shown in Figure 1, at the leading section of carbonic acid gas supply unit 1, produce turbulent flow and negative pressure part, dispersion, the dissolving of promotion carbonic acid gas A in water B, thus can be correctly and promptly control the carbonate concentration of carbonated water C.

Fig. 3 is the profile that flows that model utility is showed the carbonic acid gas in carbonic acid gas supply unit on this form of implementation and the carbonic acid gas supply unit.

As shown in Figure 3, in this form of implementation, carbonic acid gas supply unit 1, constitute and be preferably in the carbonic acid gas runner 11, have porous scutum 12, check-valves 13 and orifice plate 14 successively from the end face side towards water flow passage 21 (with reference to Fig. 1), the upstream side that is more preferably at orifice plate 14 also has orifice plate filter 15.

By such formation, can provide can be correctly and promptly control the carbonate concentration of carbonated water, thereby the carbonated water of suitable carbonate concentration or the drinking water of drinking well are provided rapidly, and simple structure, carbonated water production unit that maintainability is good, cheap.Below, be described more specifically porous scutum 12, check-valves 13, orifice plate 14 and orifice plate filter 15 respectively.

Though shape, structure as porous scutum 12 are not particularly limited, but for carbonic acid gas A being refined into air bubble-shaped and evenly spreading among the water B, the dispersion part that carbonic acid gas A must be arranged, the thickness that regulation promptly must be arranged on the flow direction of carbonic acid gas A can be enumerated the form of the garden plate shape of 40～200 times thickness with aperture described later as suitable example.Also can suitably be out of shape and be fit to the shape of internal diameter of the carbonic acid gas runner 11 of carbonic acid gas supply unit 1.

By porous scutum 12 is set, can makes the fining air bubbles of carbonic acid gas A and increase contact area with water B (with reference to Fig. 1), thereby can promote dispersion, the dissolving of carbonic acid gas A in water B.

At this moment, the aperture of porous scutum 12, preferably 10～50 μ m are more preferably 20～30 μ m.When less than 10 μ m, the circulating resistance of carbonic acid gas A is big, and feed pressure uprises, and often must improve the intensity of carbonic acid gas supply unit 1, and when surpassing 50 μ m, it is big that bubble becomes, and often dispersion, the dissolving of carbonic acid gas A in water B is insufficient.

At this,, can enumerate fluoride resins such as sintering metal, pottery, porous glass or polytetrafluoroethylene (PTFE) behind the powder such as sintered stainless steel for example etc. as the material of porous scutum 12.Wherein, also be that fluoride resin is best.Fluoride resin has water proofing property, can effectively prevent because of the adhere to even foaming that hinder carbonic acid gas A of scale in the part that contacts with water A of porous scutum 12, or water B is to intrusion of the direction of check-valves 13 etc.In addition, when the material of porous scutum 12 is hydrophilic materials such as powder sintered metal, pottery, porous glass when constituting, also can be in waterproof material such as the surface impregnation of porous scutum or coating fluoride resins.

Again, shape, structure as check-valves 13, carry out supply just passable of carbonic acid gas A smoothly so long as the refluence of carbonic acid gas A can effectively be prevented, be not particularly limited, but can enumerate for example umbrella shape as suitable example, it has the carbonic acid gas A that allows by carbonic acid gas runner 11 passes through to porous scutum 12 directions, and the function that stops the water B by water flow passage 21 to pass through to orifice plate 14 directions.Other, also utilize ball-type that spring pushes, utilize that spring pushes mushroom-shaped etc.

Constitute the umbrella shape by shape, can reduce the size of the central axis direction of carbonic acid gas supply unit 1 check-valves 13.Therefore, can make 1 miniaturization of carbonic acid gas supply unit, and because the minimizing of number of spare parts can reduce the occurrence frequency of fault.Again, because the mobile size of the part of performance check function is little, so can improve the non-return reactivity.

Again, check-valves 13 vibrations were sounded when carbonic acid gas A supplied with, and can inform the supply of carbonic acid gas.Therefore, the user can utilize the sense of hearing (sound) to confirm the supply of carbonic acid gas A, again, when sounding stops when carbonic acid gas A supplies with, can confirm equally because the carbonic acid gas in the carbonic acid gas supply container (gas bomb) 41 (with reference to Fig. 4) exhausts or what fault and the situation of carbonic acid gas A can not be provided.And, confirm the supply action of carbonic acid gas A because can not use the pressure gauge of high price or pressure switch, so be expected to reduce installation cost.

As the material of check-valves 13, but so long as getting final product of flowing backwards of effective supply carbonic acid gas A and can effectively preventing be not particularly limited, but can enumerate various rubber that for example have pliability, elasticity, corrosion resistance etc.Wherein, flexual to fluoridize class silicon rubber best even also can keep under the low temperature when carbonic acid gas is emitted.

Shape, structure as orifice plate 14, but so long as the pressure of carbonic acid gas A of appropriate regulation high pressure and getting final product of quantity delivered, be not particularly limited, but the orifice plate body 14a that can enumerate the circular plate shape of resin in handling ease [particularly, have under the good polyformaldehyde of resistance to impact (POM), polyacetals, the low temperature not the polytetrafluoroethylene (PTFE) of cracky, poly-fluorine second diene (VF2)] system goes up the form of perforating plate hole 14b.At this moment, orifice bore 14b also can have a plurality of, as its configuration, in order to prevent to make check-valves 13 impaired owing to the reduction of the temperature of the carbonic acid gas A that provides, the central shaft arrangement of the check-valves 13 that preferably staggers.

By orifice plate 14 is set, but pressure and the quantity delivered of the carbonic acid gas A of appropriate regulation high pressure.Therefore, carbonic acid gas A can supply to mixing portion 2 (with reference to Fig. 1) by a gas, thereby effectively prevents to emit suddenly to the outside from mixing portion 2 with water B (with reference to Fig. 1).Again, on carbonic acid gas supply unit 1, when the carbonic acid gas of high pressure was emitted, carbonic acid gas supply unit 1 at first was cooled, and mixing portion 2 also is cooled then, so, can effectively prevent the outside dewfall of mixing portion 2 or freeze.

The bore of orifice plate 14 (orifice bore 14b), under 1～5 liter/minute the clean water treatment amount that is used on the common home-use water purifier, when carbonic acid gas concentration is made as 30～800ppm, 0.3～0.4mm preferably.When the bore of orifice bore 14b during less than 0.3mm, processing difficulties often, and the situation of plugging hole plate hole 14b such as foreign matter takes place easily, again, often to the reactivity of on-off transfer valve also variation.Again, when surpassing 0.4mm, it is too big that the throughput of carbonic acid gas becomes, and often emits suddenly from applying nozzle when making the action of on-off transfer valve.Again, when carbonic acid gas concentration is made as 800～2000ppm, emit from applying nozzle suddenly in order to prevent the water purification that contains carbonic acid gas, preferably the central axis direction length of elongated pore plate hole 14b, compare during with the carbonic acid gas concentration of 30～800ppm, increase the circulating resistance of carbonic acid gas.

Again, in this form of implementation as shape, the structure of the orifice plate that uses as required with filter 15, so long as can effectively prevent the getting final product of obstruction of orifice bore 14b, be not particularly limited, but can enumerate the form of the circular plate shape that for example aforesaid powder sintered metal, pottery, porous glass, the fluoride resin that utilizes stainless steel etc. make.

In addition, in this form of implementation, also can be designed to use replace above-mentioned orifice plate or orifice plate and orifice plate with filter and have the formation of the 2nd porous scutum of filter function concurrently.That is, also the carbonic acid gas supply unit can be designed to have successively the formation of porous scutum, check-valves and the 2nd porous scutum from end face side towards water flow passage.At this moment, the length of the aperture of the 2nd porous scutum and central axis direction can suitably be determined according to the flow of carbonic acid gas.

Again, do not having on the carbonic acid gas supply unit under the situations such as restriction of size, the formation of porous scutum, check-valves and orifice plate, or porous scutum, check-valves, orifice plate and the orifice plate formation of filter, also can be designed to each member each or a plurality of cutting apart, and by utilizing for example flexual pipe to connect them removably, and be concentrated into the member union body, and this member union body is attached at formation on the on-off transfer valve removably.By such formation, when each member damages,, change the operation facilitation so can make, and can reduce renewal cost because can only change the member of this damage, effective especially when on the carbonic acid gas supply unit, not having size restrictions etc.

Again, the carbonic acid gas supply unit 1 in this form of implementation is preferably riveted its leading section 31, or utilizes unidirectional screw assembling.

By such formation, even when carbonic acid gas supply unit 1 wait to be decomposed by user, because its truth judges easily from the outside, so the device that can effectively prevent to continue to use because of the decomposition function reduction.

Again, O type ring 32 utilizes guard circle 33 to be arranged on the assigned position, can effectively realize the sealing between porous scutum 12 and the cover 30.In addition, on cover 30, be formed for respectively and mix the fixing external screw thread 30a between the portion 2 (with reference to Fig. 1) and be used to open check-valves 13 and make carbonic acid gas that carbonic acid gas A flows smoothly by hole 34.

Again, O type ring 35 can effectively be realized the sealing between orifice plate body 14a and the orifice bore 14b.

Again, the configuration by pressure ring 36 is for orifice plate is fixed on by between pressure ring 36 and the orifice plate body 14a with filter 15.At this moment, also can not be provided with, and orifice plate is fixed on the orifice plate body 14a with filter 15 with bonding agent etc. by pressure ring 36.

And cover 30 links by the end of pipe joint 37 with pipeline 38.As pipe joint 37, so long as simple getting final product of linking sleeve 30 and pipeline 38 is not particularly limited.As the material of pipeline 38, can enumerate the form that polyurethane resin for example etc. constitutes.The other end of pipeline 38 is attached on the carbonic acid gas supply container (gas bomb) 41 (with reference to Fig. 4).

As cover 30 shape and with the combined structure that mixes portion 2, so long as getting final product of the temperature decline can bear the pressure of carbonic acid gas and carbonic acid gas and supply with the time is not particularly limited.As its material, can enumerate the stainless steel of handling ease for example or moulding is easy and low temperature intensity is high polyformaldehyde (POM), acrylonitrile-butadiene-styrene (ABS) (ABS), polyacetals etc.Again, on the surface of cover 30, adhere to, also can plate antibacterial metals such as silver, copper in order to prevent scale.

Carbonic acid gas A's in the carbonic acid gas supply unit 1 in this form of implementation flows, shown in arrow among Fig. 3, from carbonic acid gas supply container (gas bomb) 41 (with reference to Fig. 4), via pipeline 38 and pipe joint 37, to the carbonic acid gas runner 11 that overlaps in 30, pass through hole 34 by orifice plate with filter 15, orifice bore 14b and carbonic acid gas respectively, press off check-valves 13 again, by porous scutum 12, become bubble and supply to mixing portion 2 (with reference to Fig. 1).

This form of implementation also preferably also has regularly the form of structure that the carbonic acid gas A of ormal weight is provided to carbonic acid gas supply unit 1.

Particularly, can enumerate and utilize flow described later to show, the formation of the carbonic acid gas A of ormal weight regularly is provided to carbonic acid gas supply unit 1 with liquid crystal 48 (with reference to Fig. 4) and the interior timing function of adorning.

By such formation, when even porous scutum 12 has adhered to foreign matters such as scale, when not making carbonated water C, the carbonic acid gas A of ormal weight also can regularly be provided to carbonic acid gas supply unit 1, thereby utilize the carbonic acid gas A that provides to be discharged to water flow passage 21 (with reference to Fig. 1) side attached to the foreign matters such as scale on the porous scutum 12, can guarantee the even foaming of carbonic acid gas A.

Fig. 4 is the stereogram of a form of implementation of the model utility water purifier of showing the present invention's (the 2nd invention).

As shown in Figure 4, the water purifier 20 of this form of implementation is characterised in that to have above-mentioned carbonated water production unit 10.

The water purifier 20 of this form of implementation, mobile relevant ground with carbonic acid gas also has: to the carbonic acid gas supply unit 1 of carbonated water production unit 10 provide carbonic acid gas A, be arranged on carbonic acid gas supply container (gas bomb) 41 in the shell 40 (housing main body 40a, substrate 40b) replaceably; Be attached at the control valve 42 of quantity delivered on the carbonic acid gas supply container 41, the control carbonic acid gas; Supply with or cut off the switching mechanism 43 of carbonic acid gas.

At this, shell 40 can suit to determine its volume, shape, material etc. according to the purposes of water purifier.

Particularly, when home-use water purifier, the volume that can enumerate housing main body 40a is 1～8 liter, and material is stainless steel or resin, and shape is the form of cylindrical body, but but from the viewpoint appropriate change of easy to use and appearance design.

Again, but preferably desheathing main body 40a and substrate 40b.

As carbonic acid gas supply container (gas bomb) 41, so long as convenient for collecting getting final product in shell 40 be not particularly limited, but preferably for example volume below 98 milliliters.If below 98 milliliters, because not in gases at high pressure are banned the scope of application of method, so sell, buy easily.Carbonic acid gas supply container (gas bomb) 41 is considered the situation that carbonic acid gas wherein exhausts, and is arranged on replaceably for example on the substrate 40b of shell 40.

In this form of implementation, as shown in Figure 4, be contained in carbonic acid gas supply container (gas bomb) 41 and the control valve 42 in its housing main body 40a.

The replacing of carbonic acid gas supply container (gas bomb) 41, can be undertaken by for example following method, promptly, in the switching of the side of housing main body 40a lid (not shown) is set freely, locking lid when using water purifier, change carbonic acid gas supply container (gas bomb) 41 o'clock, open the lid of housing main body 40a side, carbonic acid gas supply container (gas bomb) 41 and control valve 42 are are all come in and gone out from shell (housing main body 40a) 40a.

As in conjunction with the pipe arrangement 71 of control valve 42 with switching mechanism 43, consider the discrepancy operation of carbonic acid gas supply container (gas bomb) 41 and control valve 42 from housing main body 40a, preferably for example be configured as the helix tube with flexual polyurethane system of screw type.

As control valve 42,, have no particular limits so long as can effectively control the getting final product of quantity delivered of carbonic acid gas.

During above-mentioned form of implementation, what illustrate is the form that is contained in hypothesis home-use purposes, small-sized carbonic acid gas supply container (gas bomb) 41 and the control valve 42 in its housing main body 40a, but during the water purifier of commercial usefulness such as eating and drinking establishment, because need contain the water purification of carbonic acid gas in a large number, so, preferably adopt large-scale carbonic acid gas supply container in order to reduce the replacing frequency of carbonic acid gas supply container.

Fig. 5 is the key diagram of variation of a form of implementation of the model utility water purifier of showing the present invention's (the 2nd invention).

As shown in Figure 5, during the water purifier 20a of variation, carbonic acid gas supply container (gas bomb) 41 and control valve 42 are configured in the outside of its housing main body 40a, and utilize the pipe arrangement 40c of regulation to be connected on the water purifier main body 20b.

Again, pipe arrangement 40c is attached on the switching mechanism 43 described later (on-off transfer valve 50), and on-off transfer valve 50 becomes the formation of carrying out the on-off action by the diaphragm type packing 72 on the top that is provided in water purifier main body 20b.In addition, in this variation, as carbonated water production unit 10, applying nozzle 46, shell 40, water purification element 44 described later etc., can adopt with water purifier shown in Figure 4 20 on the same form used.

By such formation, can make a large amount of carbonated water of the capacity of corresponding large-scale carbonic acid gas supply container.

As switching mechanism 43, so long as can be smoothly and provide conscientiously or cut off getting final product of carbonic acid gas, have no particular limits, but can enumerate the form that constitutes and have secondary spring by the on-off transfer valve of button mode as suitable example.Specifically as shown in Figure 6.

Fig. 6 (a) is the exploded perspective view of the on-off transfer valve of the button mode on the form of implementation of the model utility water purifier of showing the present invention's (the 2nd invention); Fig. 6 (b) is the front view of on-off transfer valve when being off-state; Fig. 6 (c) is the front view of on-off transfer valve when being on-state; Fig. 6 (d) is the side view of on-off transfer valve when being off-state.

Shown in Fig. 6 (a)～(d), the on-off transfer valve 50 of the button mode in this form of implementation is made of on-off portion 51 and button portion 56.

On-off portion 51, dress transfer valve (not shown) in the main body 51a of on-off portion of cuboid, the carbonic acid gas that provides via gas bomb pipe arrangement 53 from carbonic acid gas supply container (gas bomb) 41 (with reference to Fig. 4) is provided, utilize on-off action (this action is undertaken by the button described later portion 56) conducting of innerspring on-off button 52 or cut off flow [constitute when flowing conducting, provide carbonic acid gas to carbonic acid gas supply unit 1 (with reference to Fig. 4)] of carbonic acid gas via carbonic acid gas supplying tubing 54.This on-off portion 51 is fixed on the installing hole 55 that is provided with on the installing plate 70 of regulation.

Again, button portion 56 is by constituting with the lower part: have pressing component 57, fixing feet 58 and jut 59, and have the main body 56a of button portion in the medium pore portion (not shown) of lower opening; Often to button portion 56 to the off-state application of force, and limit flexibly that it is up and down and relax secondary spring 60 for the direct impact of on-off button 52; In button portion 56 when up and down, the medium pore portion by button portion 56 slides along its outline from the top and makes the successfully up and down clava of button portion 56 61; Engaging of utilization sound that clicks with spring 62 with the cooperation of jut 59.Again, fixing feet 58 disposes (going up the unconfined slip of direction is to utilize the pawl restriction) slidably along through hole 63, and can carry out the elasticity of the main body 56a of button portion and the location of up and down smoothly and top dead-centre at above-below direction.Engaging is fixed on the installing plate 70 with spring 62, and jut 59, constitutes when crossing protuberance 64 with sliding on the protuberance 64 of spring 62 in engaging with clicking.Button portion 56 preferably can be fixed on the top of Fig. 4 and shell 40 shown in Figure 5 up and downly by the diaphragm type rubber packing 72 (with reference to Fig. 5) between sealing button portion 56 and the shell 40.

From the off-state shown in Fig. 6 (b), when the user of water purifier when button portion 56 is pushed by diaphragm type packing 72 in the outside of shell 40, the outline that button portion 56 bears on one side from the reaction force one edge clava 61 of secondary spring 60 slides, descends, and pushes on-off button 52 by pressing component 57.Thus, on-off transfer valve 50 becomes the on-state shown in Fig. 6 (c).At this moment, jut 59 with engage with producing click between the spring 62, the user can utilize the push action of the sense of hearing (sound) ACK button portion 56 to carry out really.

The user of water purifier when water flows (during conducting), if suitably push on-off transfer valve 50 from the outside of shell 40 (with reference to Fig. 4) by diaphragm type packing 72, then can obtain to contain the water purification of the carbonic acid gas that is hopeful concentration.That is, during water flows, if push on-off transfer valve 50 then become the water purification of the carbonic acid gas that contains maximum concentration, on the other hand, if during water flows, push on-off transfer valve 50 off and on then concentration reduces along with interval intermittently is elongated.

Also can be not limited to the pressing method of on-off transfer valve 50 and, set above-mentioned change in concentration between control valve 42 (with reference to Fig. 4) and on-off transfer valve 50 by the successive control valve (not shown) of the discharge that can change carbonic acid gas is set.

Again, also can be provided with and for example can set " aqueous mode of drinking (carbonate concentration is 30～50ppm) " well, " the carbonated water pattern of cooking usefulness (carbonate concentration is 100～160ppm) ", " little carbonated water pattern (carbonate concentration is 500～900ppm) " waits the control valve (not shown) of the necessary amount of the concentration of using always like this, and utilizes selector switch (not shown) that the user of water purifier can be selected respectively.

Equally, different in summer with outside air temperature in winter (temperature of water purification), the mixability of carbonic acid gas in water purification also dissimilates, corresponding therewith, improve the summer that the mixability of carbonic acid gas that also can be in water purification descends and set amount or the pressure of supplying with carbonic acid gas, set amount or the pressure of supplying with carbonic acid gas and reduce in the winter that the mixability of carbonic acid gas rises, or no matter outside air temperature (temperature of water purification) and the mixability of carbonic acid gas is made as necessarily.

In addition, flowing of carbonic acid gas represented with blank arrow in Fig. 4.

When carbonic acid gas offers carbonic acid gas supply unit 1 (with reference to Fig. 4) via carbonic acid gas supplying tubing 54, as previously mentioned, check-valves 13 (with reference to Fig. 1) vibration of carbonated water production unit 10, sound and inform the supply of carbonic acid gas, the user can utilize the sense of hearing (sound) to confirm the supply of carbonic acid gas, when when carbonic acid gas is supplied with, stopping to sound, can confirm equally because the carbonic acid gas in the carbonic acid gas supply container exhausts or what fault and carbonic acid gas A can not be provided again.

Again, in this form of implementation, the mobile relevant ground with water as shown in Figure 4, also has: the water that is used to purify continuously the water flow passage 21 (with reference to Fig. 1) by mixing portion 2 is made the water purification element 44 of purifying waste water; The flowmeter 45 that combines with the mixing portion 2 of carbonated water production unit 10; Leading section in mixing portion 2 can be filled into carbonated water the applying nozzle 46 of the container of regulation.

As shape, the structure of water purification element 44,, be 200～1500cm for example at volume but can enumerate if having the function and convenient for collecting then being not particularly limited in shell 40 of filter ³, material be in the casing of cylindrical body of ABS system in the form of filter cylinder type of dress filtration members (filter).Water purification element 44 when considering filtration members (filter) generation obstruction wherein etc., preferably is arranged on the substrate 40b of shell 40 replaceably.The replacing of water purification element 44 can be taken out the water purification element 44 on the substrate 40b by for example taking housing main body 40a and substrate 40b apart, loads onto new water purification element 44 and carries out.

As the material of the filtration members (filter) of water purification element 44, can enumerate for example ceramic porous article (ceramic filter) of hear resistance and excellent corrosion resistance as being fit to example.The also form of compound ceramic porous body (ceramic filter) and active carbon.

As flowmeter 45, the getting final product of flow that offer the water B before the carbonated water production unit 10 so long as can measure correctly that water source from the outside (tap of the water pipe when for example home-use) purifies via water supplying tubing 47 and by water purification element 44, without particular limitation, but for example one is buried magnet underground on the rotor of propeller-type, and detect the form of the tongue cast be embedded in the SN that utilizes the magnet in the propeller that flowing water rotates, because it is be small-sized, so best.Again, the allocation position of flowmeter 45 for the water that prevents to contain the carbonic acid gas that flows through carbonated water production unit 10 causes the misoperation that propeller rotates, is preferably disposed between water purification element 44 and the carbonated water production unit 10.

Also display part can be attached on the flowmeter 45, thereby can utilize the flow of visual confirmation water B or the flow of carbonated water C.In Fig. 4, showed and utilized flow to show the form that shows the life-span of the flow of water B and water purification element with liquid crystal 48.

Flow shows with liquid crystal 48, though for example utilize the battery 49 that does not need cord to drive for the portabillity that improves water purifier, also can utilize AC power.Utilize battery 49 or AC power, also actuable switch mechanism 43.

Again, as described above, mixing portion 2 is preferably in its leading section and has the applying nozzle 46 that carbonated water C can be filled into the regulation container.

In addition, water B's flows, and the arrow with black in Fig. 4 is represented, finally is filled in the container of regulation from applying nozzle 46 as carbonated water C.

On the water purifier of form of implementation shown in Figure 4, though adorn the water purification element in adopting in shell 40 integratedly, carbonic acid gas supply container (gas bomb), control valve, switching mechanism, the on-off transfer valve, carbonated water production unit, applying nozzle, thereby can provide suitable formation of having mixed the water purification of carbonic acid gas, but also can interiorly adorn carbonic acid gas supply container (gas bomb), control valve, switching mechanism, the on-off transfer valve, carbonated water production unit, but relatively by the water purification element and be used to guarantee pipe arrangement as the function of water purifier, nozzle, the existing water purifier that main body cover etc. constitute, prepare one with carbonic acid gas supply container (gas bomb), control valve, switching mechanism, the on-off transfer valve, carbonated water production unit, what applying nozzle constituted makes the unit that relevant parts are concentrated one with carbonated water, by water purification outlet at existing water purifier, connect and make the water purification import that relevant parts are concentrated the unit of one with carbonated water above-mentioned, can make its performance and the same function of this programme, thereby can easily the water purifier that has been provided be become the water purifier that can make carbonated water.
