Technical field
The present invention relates to a kind of drinking water feedway, this drinking water feedway is equipped with water intake valve at the intake pipe that extends out from container (tank) etc., supplies with the drinking water that stores by opening, close water intake valve in container etc.The technology of the sanitary condition in the path between in particular, the present invention relates to during the non-supply of not supplying with drinking water, can keep well from the water intake valve to the intake.
Background technology
In the past, for example in the water purifier field, be configured to the water purifier that behind the end face horizontal-extending of water purifier housing, hangs down at outlet water pipe at water purification, a kind of like this scheme has been proposed: from the air introduction part air is imported this outlet water pipe pure water inlet portion current and produce foam, make this foams mix in water, thereby make the current that flow out from pure water inlet portion become soft, and anti-sealing disperse (reference example such as patent documentation 1).
Patent documentation 1: the real fair 5-29116 communique of Japan
; for the drinking water feedway that for example is called as water dispenser (water server) or feeding engine (dispenser); when water intake valve being switched to open mode because of user's console switch; drinking water will be supplied to by the water intake valve of open mode; flow out to the outside from intake, be injected in the water tumbler in downstream-end opening.And for the drinking water feedway of this structure, in case close water intake valve, then the drinking water that does not flow out as yet in the path from the water intake valve to the intake is just stayed the inside with the delay state.For example shown in the image pattern 7 like that, when water intake valve 101 is switched into open mode (with reference to the chain-dotted line part of this figure), the intake pipe 102 of upstream side becomes the state of communicating with each other with the outlet 103 in downstream, therefore, drinking water is flowed through from intake pipe 102 behind valve chamber 104 and the outlet 103, flow out from intake 105, be injected among the water tumbler P.On the other hand, when water intake valve 101 was switched into closed condition (with reference to the solid line part of this figure), the solid stream of water that is flowing before this just was blocked, and drinking water remains in the inside of valve chamber 104 and outlet 103.
Yet because intake 105 is towards the space outerpace opening, so the drinking water that remains in outlet 103 paths such as grade contacts with the air of space outerpace at intake 105 places, therefore, on the health angle, this is not a kind of gratifying state.Particularly do not fetch water operation so continually and the long period does not fetch water when operation as the user, during this, residual drinking water maintains intake 105 places and air state of contact, and is therefore, not satisfactory.
Summary of the invention
The present invention makes in view of situation as described above, its purpose is to provide a kind of drinking water feedway: because the water intaking EO and operate to fetch water next time after water intake valve switched to closed condition and till water intake valve switched to open mode during in, can prevent that drinking water from remaining in the path between the intake from the water intake valve to the downstream.
In order to reach the purpose of the invention described above, in the present invention with such drinking water feedway as research object, that is: open and close valve is installed taking on the water intaking path of drinking water, by this open and close valve is switched to open mode, flow to intake and can fetch water from intake from the drinking water of upstream side.Aforesaid drinking water feedway has possessed following feature, has bend from above-mentioned open and close valve to the water intaking exit passageway the intake that is:; Above-mentioned bend is that boundary's bending forms with angle edge (edge like shape portion), make the path internal face of the upstream side that is positioned at above-mentioned angle edge have the gradient that rises towards above-mentioned open and close valve across above-mentioned angle edge, and make the path internal face in the downstream that is positioned at above-mentioned angle edge extend (technical scheme 1) towards the below.
Under situation of the present invention, open and close valve is switched to open mode, drinking water from upstream side water intaking path flow into the water intaking exit passageway and flows to bend, these current are effluent following time downstream crossing the angle edge, produce a kind of turbulent condition from below the edge of angle and with the downstream path internal face at the tight adjacent position of angle edge, peeling off, thus, produce the eddy current that contains air behind, generate pneumatosis at current.Then, open and close valve is switched to closed condition, the beverage current are stopped, air in the eddy current that produces below the edge of angle and with the tight adjacent position of angle edge then becomes bubble before this, path internal face along the upstroke slope of upstream side rises towards open and close valve one side under the closed condition, along with this air moves, air is drawn into from intake in the water intaking exit passageway.Thus, displacement takes place and is driven out of in water in the water intaking exit passageway and air, and falls and be discharged from from intake, becomes empty state in the water intaking exit passageway.For above-mentioned reasons, in during this section that open and close valve is switched to open mode because of water intaking operation next time, can prevent that drinking water from remaining in the water intaking exit passageway, take place thereby can avoid when having drinking water residual contingent bacterium to sneak into, grow such situation reliably, can keep good sanitary condition.
In the present invention, can make the two path internal faces in upstream side and downstream clip above-mentioned angle edge and intersect, make from above-mentioned open and close valve and peel off (technical scheme 2) along current path internal face from the downstream when crossing above-mentioned angle edge that the water intaking exit passageway flows down.In this case, can be used in below the edge of angle and produce the eddy current that contains air with the tight adjacent position of angle edge, the structure of the angle edge that generates pneumatosis is more specific, can obtain the effect of technical scheme 1 more clearly.
In addition, as above-mentioned water intaking exit passageway, have inclined path portion and exit passageway portion, this inclined path portion tiltedly extends the below towards the front side direction of water tumbler mounting table, this exit passageway portion roughly vertical extends to intake, above-mentioned angle edge be can be by making above-mentioned inclined path portion downstream be connected (technical scheme 3 or the technical scheme 4) that forms with cross one another state with the upstream extremity of above-mentioned exit passageway portion.Like this, the structure of water intaking exit passageway with angle edge is more specific, can obtain the effect of technical scheme 1 more clearly.And, owing to have inclined path portion, the visuality of user to the intake situation can also be improved in more on the front the position of intake position configuration on the water tumbler mounting table of exit passageway portion.Thus, can observe the situation that water comes out, stops from intake in the limit, the limit can be easily and the operation of fetching water reliably.
Can also near the path internal face of the position downstream of above-mentioned angle edge, connect to be formed with and suck the hole (technical scheme 5) that air is used.Like this, when below the edge of angle and with the tight adjacent position formation of angle edge, containing the eddy current of air, air is sucked from above-mentioned hole, generate pneumatosis easily, and switching open and close valve to closed condition and current when stopping, the path internal face of the upstroke slope from the hole leaked-in air along upstream side moves up.Thus, than the situation that does not have the hole, thereby can be rapidly and the water in the exit passageway of will fetching water reliably be replaced as air water driven out of.
As explained above such, according to drinking water feedway of the present invention, when the drinking water of inflow water intaking exit passageway flows to bend when water intaking, these current are when crossing the angle edge effluent goes downstream, from below the edge of angle and with the downstream path internal face at the tight adjacent position of angle edge, peeling off and producing a kind of turbulent condition, can make current produce the eddy current that contains air behind and generate pneumatosis thus.Therefore, when water intaking finishes and during mobile the stopping of drinking water, air in the eddy current that produces below the edge of angle and with the tight adjacent position of angle edge becomes bubble before this, this bubble moves up along the path internal face of the upstroke slope of upstream side, be accompanied by moving of this air, air is sucked from intake in the water intaking exit passageway, can with air displacement it be driven out of by the water in the exit passageway of will fetch water thus, makes the state that becomes sky in the exit passageway of fetching water.Thus, can prevent that sealing remains in the water intaking exit passageway in during this section that open and close valve is switched to open mode because of water intaking operation next time.Therefore, can avoid when having water residual contingent bacterium to sneak into, grow such situation reliably and take place, thereby keep good sanitary condition.
Particularly according to technical scheme 2, peel off in order to make from current path internal face from the downstream when crossing the angle edge of flowing down of water intaking exit passageway, and the two path internal faces that make upstream side and downstream clip the angle edge and intersect, thereby make to be used for below the edge of angle and to produce containing the eddy current of air and to generate the structure of angle edge of pneumatosis more specific, can obtain above-mentioned effect of the present invention more clearly with the tight adjacent position of angle edge.
In addition, according to technical scheme 3 or technical scheme 4, as the water intaking exit passageway, the inclined path portion that has exit passageway portion and extend towards the oblique below of the front side direction of water tumbler mounting table, and be connected with cross one another state with the upstream extremity of exit passageway portion by the downstream that makes inclined path portion and form the angle edge, make the structure of water intaking exit passageway more specific, can obtain above-mentioned effect of the present invention more clearly with angle edge.And, owing to be provided with inclined path portion, so can improve the visuality of user with the intake position of exit passageway portion in the position more on the front that is configured in the water tumbler mounting table to the intake situation.Thus, can observe the situation that water comes out, stops from intake in the limit, the limit can be easily and the operation of fetching water reliably.
And, according to technical scheme 5, suck the hole that air is used by near the path internal face of the position downstream of angle edge, connecting to be formed with, than the situation that does not have the hole, thus can be rapidly and make water in the water intaking exit passageway be replaced as air reliably water is driven out of.

First embodiment
In having above integrally-built drinking water feedway, as shown in Figure 4, constitute from as the cold water water intake valve 27 of open and close valve to the water intaking outlet 28 of the path of intake 281, the position is formed with bend 282 near intake 281.Crooked mode forms this bend 282 to have angle edge 283.Promptly this bend 282 is not crooked sleekly, and its gradient or gradient that forms the inner surface that drinking water flows through is that rapid variation takes place on the boundary with angle edge 283.And, form that the path internal face 284 that is positioned at the upstream side of angle edge 283 across angle edge 283 becomes towards water intake valve 27 and acclivity.Above-mentioned water intaking outlet 28 constitutes the water intaking exit passageway that is formed by pipeline.
Explanation in further detail.As shown in Figure 4, water intaking outlet 28 is communicated with valve chamber 272, and extends to cold water intake 281, and this valve chamber 272 is used to accommodate the spool 271 of cold water water intake valve 27, when spool 271 switched to open mode, cold water (drinking water) flowed into valve chamber 272 from cold water intake pipe 26.Illustrative water intaking outlet 28 comprises sagging passage portion 285, inclined path portion 286 and exit passageway portion 287 among the figure, this sagging passage portion 285 is communicated with valve chamber 272, sagging slightly roughly vertically, this inclined path portion 286 becomes the shape that goes up a slope at least with path internal face 284 mode it seems to declivity and from the front surface side of the water tumbler mounting table 13 of housing 1 and extends to the front of water tumbler mounting table 13 that this exit passageway portion 287 hangs down into intake 281 roughly vertically.And inclined path portion 286 and exit passageway portion 287 intersect, thereby constitute bend 282.In addition, the path internal face 284 of inclined path portion 286 intersects with the angle of cut α of the path internal face 288 of exit passageway portion 287 with regulation, thereby, utilize the formed angle of this boundary line to constitute angle edge (edge like shape portion) 283.Above-mentioned angle of cut α is MIN necessary condition with the scope of 0 °＜α＜90 °, even to be preferably maximum also be angle less than 60 ° angular range, wherein preferably the value of α is set in 45 °～60 ° the angular range.At this moment, dispose vertically,, can suppress as far as possible to disperse thus so cold water can be injected among the water tumbler P vertically owing to will form the side's of angle of cut α exit passageway portion 287.Aforesaid water intaking outlet 28 can form with molding synthetic resin, perhaps also can adopt method formation one such as welding with metal tube.
Being switched into open mode by cold water water intake valve 27 makes the cold water from cold water intake pipe 26 flow into water intaking outlet 28, flow to bend 282 then as mentioned above like that, at this moment, shown in Fig. 5 (a), cross angle edge 283 and when flowing into exit passageway portion 287 along the current that especially flow to angle edge 283 positions of inclined path portion 286 along path internal face 284, from peeling off near the below of the most inboard angle edge 283 and with the path internal face 288 at the tight adjacent position of angle edge 283, thereby produced a kind of turbulent condition behind at current, afterwards, (with reference to Fig. 3 or Fig. 4) falls and cold water is injected into the water tumbler current from intake 281 towards water tumbler.And, leave path internal face 288 owing to cross the current of above-mentioned angle edge 283, so below the angle edge 283 and and the path internal face 288 at the tight adjacent position of angle edge 283 and the current that left path internal face 288 between generation contain the eddy current of air, generate pneumatosis thus.
Then, when cold water water intake valve 27 (with reference to Fig. 4) is switched into closed condition and utilizes spool 271 that the downstream 262 of cold water intake pipe 26 is closed, be stopped from the Cold water supply of cold water intake pipe 26.On the other hand, shown in Fig. 5 (b), air in the eddy current that produces below angle edge 283 and with the tight adjacent position of angle edge 283 in feeding cold water becomes bubble K1 and is mobile on valve chamber 272 (with reference to Fig. 4) side direction inclined path portion 286 in before, and be accompanied by moving of this air, air is drawn into from intake 281 in the exit passageway portion 287 and is become air bolus K2, and this air bolus K2 moves on along path internal face 288,284 towards valve chamber 272 side direction.By move on such bubble K1, the air bolus K2 and with valve chamber 272, sagging passage portion 285, inclined path portion 286 and exit passageway portion 287 in the water displacement, and make water be driven out of and fall from intake 281, be injected in the water tumbler P.And to the last, the water that is present in valve chamber 272, sagging passage portion 285, inclined path portion 286 and the exit passageway portion 287 all is replaced as air and is discharged to the outside.
Like this, the valve chamber 272 of cold water water intake valve 27 and water intaking outlet 28 maintain empty state when taking cold water (drinking water) next time till, based on water intaking operation next time and cold water water intake valve 27 when being switched into open mode, become the valve chamber 272 and the water intaking outlet 28 of empty state before flowing to from the cold water of cold water intake pipe 26.
As mentioned above, operate between the water intaking operation next time from this water intaking, with compare with the situation that the air of space outerpace contact in cold water remains in water intaking outlet 28 and at intake 281 places, the situation of above-mentioned first embodiment can with than the downstream 262 of cold water intake pipe 26 by in downstream and the path till intake 281, promptly comprise the state that maintain sky in the whole water intaking outlet 28 of valve chamber 272.Therefore, can avoid sneaking into the possibility of bacterium, all possibilities of this bacteria breed, can keep good sanitary condition thus in the inside of the water intaking outlet 28 that comprises valve chamber 272.And, when cold water water intake valve 27 being switched to open mode because of water intaking operation next time, the state cold water down that sterilization has been carried out in the ultraviolet ray irradiation of being sent by ultraviolet lamp 29a flow into water intaking outlet 28 in cold water intake pipe 26, this cold water that kill bacterium is injected into the water tumbler P from cold water intake 281.
In addition, in water intaking outlet 28, inclined path portion 286 it seems towards the front that from the front surface side of the water tumbler mounting table 13 of housing 1 tiltedly down extending the back is connected with exit passageway portion 287, therefore, compare with the situation of position under intake 105 (with reference to Fig. 7) is configured in cold water water intake valve 27, exit passageway portion 287 and intake 281 can be positioned at the more forward position in the space that constitutes water tumbler mounting table 13.Therefore, operation cold water can be clear that exit passageway portion 287 and intake 281 with the user's of intake switch 16 angle from operating in order to fetch water, and can the limit observation carry out above-mentioned water intaking operation from intake 281 to the situation limit that water tumbler P injects cold water.In other words, the operator need not bend over, and just can see intake 281 etc. with stance, can be with the operation of fetching water of posture like a cork.
Second embodiment
Fig. 6 represents the water intaking outlet 28a in the drinking water feedway of second embodiment.This second embodiment only sucks on hole 289 this point that air uses differently with first embodiment having formed on the water intaking outlet 28a, and other aspects and first embodiment are identical, have structure and the action effect identical with first embodiment.Thereby, in the following description, mainly describe with regard to difference, for identical structure, the Reference numeral that mark is identical omits the detailed description that repeats.
