"Manual mixing valve", [online], Hayakawa Industrial Co., Ltd. [search on November 20, 2015], Internet <URL: http://www.hayakawa-sanki.co.jp/products/?id= 1338290677-785575>

  In the valve device of Non-Patent Document 1 shown in FIG. 8, the mixing cap 15 mixes the carbonated water flowing down from the umbrella 14 with the stock solution spouted from the supply pore 12 provided on the tip side of the stock solution nozzle 11. A relatively large amount of carbonated water is supplied from the holes around the umbrella 14 into the mixing cap 15 like a shower, and the stock solution is spouted from the feed pore 12 of the stock solution there, so carbon dioxide gas is released. There is a tendency to become slightly carbonated. Then, there is a problem that it is not suitable for consumers who prefer strong carbonation.

  On the other hand, in the carbonated water discharge valve of Patent Document 1, the carbonated water is decompressed in a passage having a sufficient length and cross-sectional area by the gap formed between the cylindrical cone and the cylindrical space portion. As compared with the valve device of Patent Document 1, the carbon dioxide gas escapes less. In the lower part of the cylindrical cone, carbonated water is allowed to flow along the wall surrounding the straightening portion by the U-shaped groove provided on the outer circumference of the straightening portion. The flow of carbonated water from the gap formed between the inner circumferential surface and the carbonated beverage outlet becomes smooth, and the escape of carbon dioxide gas is reduced, and as a result, a relatively carbonated carbonated beverage can be provided. become.

  However, in the valve of Patent Document 1, when forming a cylindrical space portion or a cylindrical cone, it is difficult to form a highly accurate molding in which the gap between the two is uniform. That is, in order to make the annular gap uniform, it is ideally necessary to make both the cylindrical space portion and the cylindrical cone circular, and to assemble the cylindrical cone exactly concentric to the cylindrical space portion. However, such molding and assembly are difficult and often errors occur. In particular, in Patent Document 1, since the cylindrical cone is attached to the straight tube-like beverage stock solution supply pipe in the state of the inner seal, the possibility that the cylindrical cone is attached with a slight inclination is also high. As a result, there is a problem that the gap with the cylindrical space, which is a pressure reduction passage of carbonated water, can not be sufficiently secured while being nonuniform, and uneven mixing occurs with the beverage stock solution.

  Further, since carbonated water at a low temperature (about 3 ° C.) flows in the gap between the cylindrical space and the cylindrical cone, they are cooled and thermally shrunk. In particular, the die part forming the cylindrical space part is thinner than the cylindrical cone, so the contraction rate is large, and there is also a problem that the gap is partially closed due to the difference in contraction between the two.

  The present invention has been made to solve the above-described problems, and an object thereof is to disclose a dispenser for a carbonated beverage server which can stably provide a relatively strong carbonated carbonated beverage. It is.

  In order to achieve the above-mentioned object, in the present invention, the carbonated water is introduced to the valve main body provided with the carbonated water supply valve and the beverage stock solution supply valve so as to be simultaneously opened and closed via the carbonated water supply valve. A circular recess is provided in the vertical direction, and a straight tube-shaped stock solution nozzle for supplying the stock solution through the supply valve of the stock solution is provided concentrically on the inner side of the circular recess, and a flat surface is provided in the middle of the stock solution nozzle. It is a dispenser for carbonated beverages, which is provided with an optical gear-like umbrella body and mixes and discharges carbonated water passing through the umbrella body and a beverage stock solution supplied from the stock solution nozzle, wherein the stock solution nozzle A hollow round rod body having a nozzle cover attached and a hollow cylindrical cone watertightly fitted to the circular recess, the nozzle cover having a central hole through which the stock solution nozzle is vertically penetrated, and the hollow round rod Outward flange-like on the outer periphery of the rod body The cylindrical cone is integrally formed with the formed umbrella, and the cylindrical cone has a circular hole in cross section for inserting the hollow round rod at the center, and is disposed coaxially with the nozzle cover on the upper stage of the umbrella. The carbonated water is used as the depressurizing flow path as an annular narrow gap between the circular hole of the cross section of the cylindrical cone and the upper half of the hollow round rod inserted into the circular hole of the cross section; A means of configuring to supply was used.

  According to the above means, the carbonated water is depressurized in the annular narrow depressurizing flow path formed between the circular hole of the cross section of the cylindrical cone and the upper half of the hollow round bar of the nozzle cover to the umbrella body It flows with. For this reason, carbonated water is transmitted gently through the umbrella body, so carbon dioxide is less likely to be released as compared with the non-patent document 1, and a relatively strong carbonated carbonated beverage can be provided.

  Further, in the above-described means, since the cylindrical cone is watertightly fitted to the circular recess in the state of the outer seal, the cylinder is more cylindrical than in the case where the cylindrical cone is attached to the undiluted solution nozzle in the state of the inner seal. It is easy to fit the conical cone vertically in the circular recess. Furthermore, even if the cylindrical cone or the circular recess is not a perfect circle, the error can be absorbed by the seal ring. Furthermore, since the circular hole of the cross section of the cylindrical cone is used as the flow path of carbonated water, both of them are simultaneously cooled as the flow path of carbonated water between the cylindrical cone and the cylindrical space as in Patent Document 1. The degree of thermal contraction is much smaller than in the configuration described above.

  In the above means, the carbonated water having passed through the cylindrical cone travels through the lower umbrella body and finally travels through the lower half of the hollow round bar at the nozzle cover. Then, it becomes possible to mix uniformly with carbonated water by employ | adopting what provided the supply pore of the drink undiluted | stock solution with multiple horizontal direction in the lower peripheral wall as a undiluted | stock solution nozzle. At that time, the nozzle cover has a length such that the lower half of the nozzle cover covers the lower peripheral wall of the undiluted solution nozzle, and the valve main body is a hollow cylindrical mixture in which the umbrella body of the nozzle cover is accommodated therein. By attaching the cap removably, the carbonated water can be prevented by mixing the carbonated water while preventing the carbonated water passing along the umbrella body and the beverage stock solution coming out horizontally from the feed pores of the stock solution nozzle from being scattered around. It can be poured out downwards.

  Furthermore, the mixing cap has a length that accommodates the umbrella body or less of the nozzle cover, and the upper large diameter portion that accommodates the umbrella body inside, and the reduced diameter step portion from the upper large diameter portion. A lower small diameter portion accommodating the lower half portion of the hollow round bar lower than the umbrella body of the nozzle cover is provided, and a space between the lower small diameter portion and the nozzle cover is a final flow path of carbonated water Preferably, the carbonated water flowing down the umbrella body has a narrow cross-sectional area capable of rectifying.

  According to this means, the pressure-reduced flow path on the upstream side of the umbrella reduces the pressure, and the carbonated water flowing down the umbrella is rectified in the final step before mixing with the beverage stock solution, and a donut shape having a narrow cross-sectional area Since the flow path suppresses the foaming, a strong carbonated carbonated beverage can be provided more reliably.

  In addition, it is preferable that the final flow path be formed such that the lower small diameter portion of the mixing cap and the lower half portion of the nozzle cover have a uniform inner diameter and an outer diameter in the length direction. This is because the cross section of the final flow path becomes uniform up and down, and the carbonated water is rectified in a laminar flow state, so that the bubbling of the carbonated water can be more reliably suppressed.

  When the carbonated water is introduced into the upper surface side recessed portion by circularly indenting the upper surface and the lower surface of the cylindrical cone, and when the carbonated water is discharged to the lower surface side recessed portion through the pressure reducing channel. Functions as a buffer that reduces the flow velocity and pressure, and can more reliably suppress foaming of carbonated water.

  According to the present invention, since the hollow cylindrical cylindrical cone forming the pressure reduction channel of carbonated water with the nozzle cover is fitted in the circular recess on the valve main body side in the state of the outer seal, the cylindrical cone Can be more reliably assembled concentrically with the stock solution nozzle, and there is almost no thermal contraction due to low temperature carbonated water, and temporarily, even if the outer shape of the cylindrical cone or the circular recess is not perfect, by the seal ring It can absorb errors. Therefore, the pressure reduction channel of carbonated water can be assuredly ensured, and a relatively strong carbonated carbonated beverage can be stably provided.

  In addition, since the umbrella body is integrally formed on the nozzle cover, the number of parts is reduced, the assembly is easy, the members are assembled without falling off, and the members are not lost.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the attached drawings. FIG. 1 is an exploded view of a pouring device according to an embodiment of the present invention, from the top, 10 is a valve body, 20 is a cylindrical cone, 30 is a nozzle cover, and 40 is a mixing cap.

  The valve body 10 itself includes the upstream portion (a control lever 1, a stock solution lever 2, a carbonated water lever 3, a valve 4.5, a return spring 6, a valve block 7, an orifice 8 and 9). The same parts as in the apparatus of non-patent document 1 are assigned the same reference numerals as in FIG. 8 to omit the detailed description, and the parts necessary for the present invention will On the secondary side of the valve 5, as shown in FIG. 2, a space 17 for initially introducing carbonated water through the carbonated water flow path 13 is formed, continuously with the space 17 and having a circular shape on the lower side. The recess 18 is formed in the vertical direction. Reference numeral 19 denotes a base provided on the lower surface of the valve body 10 for mounting the mixing cap 40, and a circular recess 18 is formed in the inside.

  Carbonated water is introduced from the carbonated water flow path 13 into a space 17 in the upper stage of the circular recess 18 so as to draw a circle.

  On the other hand, a stock solution flow path 5 a is formed on the secondary side of the valve 4 of the stock solution, and is in communication with the stock solution nozzle 11. The stock solution nozzle 11 is integral with the valve main body 10, and is vertically concentrically provided on the inside of the circular recess 18 concentrically. Further, although the lower surface is closed, the lower peripheral wall is provided with a supply pore 12 for discharging the stock solution in the horizontal direction. In the case of this embodiment, a total of four supply pores 12 are provided at intervals of 90 degrees, but the invention is not limited to this.

  As shown in FIGS. 2 to 5, the cylindrical cone 20 has a hollow cylindrical shape in which a circular cross-sectional hole 21 through which a hollow round bar 31 (upper half 31 a) described later of the nozzle cover 30 is inserted The outer diameter of the seal member 22 is slightly smaller than the inner diameter of the circular recess 18 of the valve main body 10, and a seal ring 22 such as an O-ring is mounted on the outer peripheral surface thereof. The seal ring 22 allows the cylindrical cone 20 to be watertightly fitted inside the circular recess 18 in the form of an outer seal. On the other hand, as shown in FIG. 3, the cross-sectional circular hole 21 has an inner diameter that allows an annular gap DC to be formed between the hollow circular rod body 31 and the circular recess 18 when fitted in the circular recess 18. And although this annular gap DC functions as a pressure reduction channel of carbonated water, the details will be described later.

  Moreover, in this embodiment, the circular recessed part 23 * 24 of predetermined depth is formed in the upper surface and lower surface of the cylindrical cone 20. As shown in FIG. Of these recesses, the upper surface-side recess 23 has a cross-sectional shape with a downward taper, and in a state in which the cylindrical cone 20 is fitted in the circular recess 18, a space is provided continuously with the space 17 for initially introducing carbonated water. It has a buffer function to weaken the centrifugal force (flow velocity and pressure) of the carbonated water introduced into the portion 17 so as to draw a circle, and reliably guides the carbonated water to the cross-sectional circular hole 21.

  On the other hand, the concave portion 24 on the lower surface side has a divergent cross-sectional shape and gently supplies carbonated water to an umbrella body 33 of the nozzle cover 30 described later via the annular gap DC.

  As shown in FIGS. 2 to 6, the nozzle cover 30 has a central hole 32 through which the stock solution nozzle 11 is inserted at the center of a round rod 31 having the same length as the stock solution nozzle 11, and the round surface The umbrella body 33 is integrally formed so as to be located substantially at the center of the rod 31 in the vertical direction. The umbrella body 33 is a planar view gear shape which provided the several U-shaped groove | channel 33a in the outer peripheral edge at equal intervals, as shown in FIG. Further, in this embodiment, the lower surface of the umbrella body 33 is raised in a substantially conical shape downward.

  The nozzle cover 30 is mounted on the stock solution nozzle 11 after the cylindrical cone 20 is assembled to the valve body 10, and the center hole 32 is provided with a seal ring 34, whereby the stock solution nozzle 11 is internally sealed. It is designed to be watertightly installed.

  The mixing cap 40 is a hollow cylindrical member mounted on the lower surface of the valve main body 1 after mounting the cylindrical cone 20 and the nozzle cover 30, and as shown in FIG. The lower half 31b of the lower round bar 31 is accommodated in the inside, and the outer diameter of the lower part 41 is a slightly narrowing shape, and the dilution liquid of the beverage stock solution with carbonated water, that is, carbonated beverage is poured out from the lower surface opening 41 Is the final nozzle of this device.

  According to the pouring device of the above-mentioned configuration, the cylindrical cone 20 is fitted from the lower side of the valve main body 10 into the circular recess 18 while inserting the stock solution nozzle 11 into the circular hole 21 of the cross section. Finally, the assembly is completed by attaching the mixing cap 40. At this time, since the cylindrical cone 20 is fitted in the circular recess 18 in the state of the outer seal, it can be assembled straight on concentric with the stock solution nozzle 11. Further, even if the inner periphery of the circular recess 18 and the outer periphery of the cylindrical cone 20 are not perfect circles and are slightly distorted, the seal ring 22 absorbs the distortion and the cross section circular hole 21 of the cylindrical cone 20 The interval with the undiluted solution nozzle 11 becomes uniform, and furthermore, the nozzle cover 30 is also mounted on the undiluted solution nozzle 11 completely concentrically. As a result, the cross section circular hole 21 of the cylindrical cone 20 and the umbrella of the nozzle cover 30 A narrow annular depressurization channel DC can be formed uniformly in the upper and lower direction between the upper half portion 31a and the lower half 33 of the round bar.

  The pressure reducing channel (gap) DC is, for example, a very narrow diameter of 0.085 mm, with the inner diameter of the circular hole 21 of the cylindrical cone 20 being 13.17 mm and the outer diameter of the round bar 31 of the nozzle cover 30 being 13 mm. It can be set to any width. As shown in FIG. 5, it can be seen that this width is so small that it can not be determined by the naked eye unless it is enlarged by a considerable factor.

After the assembly is completed, the carbonated water is introduced in the order of the valve 5, the carbonated water flow path 13 and the space 17 on the upstream side of the valve body 10 by operating the operation lever of the valve body 10 to the open side. Then, through the upper surface recess 23 of the cylindrical cone 20, the space between the circular hole 21 in cross section and the upper half portion 31a of the nozzle cover 30 is sewn and led to the umbrella 33. At this time, since the cylindrical cone 20 is an outer seal, the carbonated water does not go around the circular recess 18 of the valve body 1. Therefore, the circular recess 18 (the base portion 24) is never thermally shrunk by the low temperature carbonated water. In the cylindrical cone 20 as well, the cross-sectional circular hole 21 forming the depressurized flow path of carbonated water has a sufficiently smaller surface area than the outer peripheral surface, and the cross-sectional circular hole 21 to the outer peripheral surface is sufficiently thick. There is little or negligible amount of thermal contraction of the cylindrical cone 20 due to low temperature carbonated water. Accordingly, the inner diameter of the cross-sectional circular hole 21 is maintained at the time of molding, and the gap DC with the upper half portion 31 a of the nozzle cover 30 is also maintained as a uniform annular shape. Therefore, carbonated water can be stably supplied to the umbrella body 33 in a relatively strong carbonic acid state, and as a result, a relatively strong carbonated carbonated beverage can be stably supplied.

  Further, in this embodiment, since the supply pore 12 of the stock solution nozzle 11 is covered by the lower half portion 31b of the round rod body of the nozzle cover 30, the beverage concentrate discharged from the supply pore 12 is supplied downward by the nozzle cover 30. As a result, the stock solution of the beverage does not directly adhere to the mixing cap 40. Therefore, it is possible to more uniformly mix the carbonated water transmitted along the outer periphery of the lower half portion 41a of the round bar from the pressure reducing channel via the umbrella body 33 with the beverage stock solution. In addition, even when the beverage stock solution is changed to another one, cleaning of the mixing cap 40 is unnecessary only by replacing the nozzle cover 30.

  In addition, the mixing cap 40 in this embodiment, as the internal structure thereof is shown in FIG. A two-stage configuration is provided having a diameter portion 43 and a lower small diameter portion 44 that accommodates the nozzle cover 30 at the lower portion. Among them, the lower side small diameter portion 44 has the same inner diameter in the upper and lower longitudinal direction, and forms a toroidal flow path 50 between it and the lower half portion 31b of the round bar body of the nozzle cover 30. .

  The flow path 50 is the final flow path before mixing the carbonated water flowing down the umbrella body 33 with the beverage stock solution supplied from the nozzle cover 30, and the cross-sectional area thereof is a value that suppresses foaming of the carbonated water. It is set. That is, in order to further suppress the bubbling of carbonated water, it is preferable to reduce the clearance between the inner diameter of the lower small diameter portion 44 of the mixing cap 40 and the outer diameter of the nozzle cover 30 to further reduce the cross-sectional area.

  Furthermore, in this embodiment, in order to prevent the carbonated water from causing turbulent flow in the final flow passage 50, the cross-sectional area of the flow passage 50 is made uniform over the upper and lower sides so that the carbonated water flows in a laminar flow state to suppress foaming. There is. However, as shown in FIG. 7, the mixing cap may be a mixing cap 60 configured not to have a step by continuously providing a straight portion 61 and a tapered portion 62 inside thereof.

  As described above, in the present embodiment, since the flow path until the carbonated water introduced into the valve main body 10 is mixed with the beverage stock solution by the mixing cap 40 is narrowed to make the flow rate gentle, By the time it passes, foaming of carbonation is suppressed, and a carbonated beverage of strong carbonate can be supplied.

  Moreover, in the nozzle cover 30, since the umbrella body 33 which was conventionally separate body is integrally molded with the round bar body 31 used as a main body, drop-off | omission and loss of the member at the time of incorporation are prevented.

  Further, since the cylindrical cone 20 and the nozzle cover 30 are hardly distorted due to thermal contraction by carbonated water, a product of stable dimensions can be mass-produced, and the gap DC between both can be made as small as 0.085 mm mentioned above. Can be realized with high accuracy.
