Description

[Detailed Description of the Invention] [Industrial field of application] The present invention incorporates a beverage dispenser or the like, and mixes syrup and carbonated water that have been separately fed via a beverage supply valve to prepare a carbonated beverage. The present invention relates to the structure of a carbonated beverage adjuster which supplies the discharged beverage to a cup.

[Conventional technology]

As a carbonated beverage regulator described above, it is equipped on the discharge side of the beverage supply valve, mixes the syrup sent through the valve and carbonated water, discharges it to the cup, and at the same time adjusts the mixing ratio of carbonated water. A structure having such a structure is known from Japanese Utility Model Publication No. 51-19246.

The outline of the carbonated beverage adjuster will be described with reference to FIG. 5. In the figure, 1 is a beverage supply valve, 2 is a carbonated beverage adjuster mounted on the discharge side of the valve 1, and the carbonated beverage adjuster 2 A discharge housing 5 is formed at the top of the syrup, and a carbonated water passage 4 is opened on the outer peripheral side of the syrup passage 3 in the center toward the lower side. A carbonated water flow passage 6a communicating with the carbonated water passage 4 is opened, and a sleeve 6 having a conical shaped carbonated water discharge space formed therein is fitted and fixed to the housing with an adhesive or the like. Further, inside the sleeve 6, a conical portion 7 having a shape corresponding to the conical carbonated water discharge space, a syrup discharge passage 7a which is bored in the center of the conical portion and communicates with the syrup passage 3, and the discharge passage. An adjusting body 9 having a syrup nozzle 8 projecting from the lower surface side of the conical portion in a continuous manner is fitted and deployed, and the adjusting body 9 is screwed to and supported by the top of the sleeve 6. Further, a carbonated beverage mixing space 11 is defined on the outer peripheral surface of the sleeve 6 through a liquid-tight seal ring 10, and a spout 13 having a carbonated beverage outlet 12 opened on the lower surface is detachably attached. . 1a is an opening / closing operation lever of the beverage supply valve 1.

With such a configuration, the cup 14 is contacted with the opening / closing operation lever 1a to open the beverage supply valve 1, so that the syrup and carbonated water are separately delivered to the carbonated beverage adjuster 2 through the syrup passage 3 and the carbonated water passage 4. To be done. First, the syrup is fed through the syrup discharge passage 7a of the adjusting body 9 to the syrup nozzle 8
From the spout 13 into the carbonated beverage mixing space 11. On the other hand, the carbonated water flows out through the carbonated water flow passage 6a of the sleeve 6 into the carbonated water discharge space, and then flows down the narrow gap 15 between the inner peripheral surface of the sleeve 6 and the peripheral surface of the conical portion of the adjusting body 9. It flows into the spout 13 and mixes with the syrup to make a carbonated drink. Further, the carbonated drink is discharged and supplied into the cup 14 through the carbonated drink discharge port 12 of the spout 13.

On the other hand, when adjusting the carbonated water mixing ratio of carbonated drinks,
By rotating the adjusting body 9 to the left or right with the spout 13 pulled off, the adjusting body 9 moves up and down along the screw between the sleeve 6 and the inner peripheral surface of the sleeve 6 and the conical portion 7. The gap dimension d with the outer peripheral surface, that is, the flow channel cross-sectional area of the carbonated water changes. This makes it possible to adjust the flow rate of carbonated water, and thus the mixing ratio of carbonated water and syrup, over a wide range. Further, when the inside of the adjuster is washed, the spout 13 is disengaged, and the adjusting body 9 is screwed to be removed from the sleeve 6, so that the spout, the adjusting body, and the inside of the sleeve can be washed.

[Problems to be solved by the device]

However, the above-described conventional configuration has the following problems in terms of maintainability. That is, since the sleeve 6 is bonded to the inside of the discharge housing 5 of the main body and the adjusting body 9 is screwed to the sleeve 6, when the syrup or the like adheres to and solidifies on the threaded connecting portion of the adjusting body 9, the adjusting body is fixed. It will be difficult to remove. Further, since the sleeve 6 cannot be removed, the carbonated water flow passage opened in the sleeve.
It is difficult to clean 6a.

Then, this invention is made | formed in view of the above-mentioned point, and an object of this invention is to provide the drink regulator excellent in maintainability and handleability which can perform assembly, disassembly, washing, etc. of components easily.

[Means for Solving the Problems]

In order to achieve such an object, the carbonated beverage controller according to the present invention has a syrup discharge port that opens to the syrup passageway at the center of the lower surface, and has a conical carbonate shape that surrounds the syrup discharge port and leads to the carbonated water passageway. A discharge housing having an opening for water discharge space, a conical cylinder portion having a shape corresponding to the carbonated water discharge space and having a plurality of rows of carbonated water passage grooves formed on the outer peripheral surface, and protruding downward from the conical cylinder portion. And a syrup nozzle communicating with the syrup discharge port, and a projecting rib provided on the bottom surface of the conical cylinder portion. The adjustment is loosely fitted into the carbonated water discharge space of the discharge housing from below. A body, a carbonated drink outlet opening downward, and a stopper protruding laterally from the outer surface of the upper portion, and is fitted in a liquid-tight manner to the outer peripheral portion of the discharge housing, and has a protrusion of the adjusting body. A cylindrical spout that abuts a rib and carries the adjusting body; a substrate; a spout insertion window formed in the substrate for passing the spout; and an attachment to the spout insertion window for passing a stopper of the spout. And a tapered support pedestal that engages with the stopper of the spout when the spout is inserted into the spout insertion window and the spout is fitted to the outer peripheral portion of the discharge housing,
The stopper comprises a spout holding mechanism capable of vertically moving the adjusting body together with the spout by rotating the spout engaged with the support base.

[Action]

With the above structure, the adjusting body is carried by the spout without being screwed and is loosely fitted and held at a predetermined position in the discharge housing. Therefore, the adjusting body can be easily removed from the main body together with the spout without adhesion or solidification of the syrup. Can be washed. The spout holding mechanism is, for example, a bayonet-type locking and holding mechanism having a tapered support pedestal that engages with a stopper that projects laterally from the outer peripheral surface of the spout,
Here, by rotating the spout along the tapered surface on the support base, the adjusting body moves up and down together with the spout in the assembled state. As a result, the size of the gap between the inner peripheral surface of the discharge housing and the conical cylindrical portion of the adjusting body changes, and the carbonated water mixing ratio can be easily adjusted without disassembling the parts. .

〔Example〕

1 to 3 are assembly configuration diagrams of an embodiment of the present invention,
FIG. 4 shows the structure of the adjusting body, and the same parts corresponding to those in FIG. 5 are designated by the same reference numerals. First of all,
In FIG. 2, the body of the carbonated beverage adjuster 2 has a conical shape that opens downward and opens to the syrup discharge port 3a of the syrup passage 3 and the carbonated water passage 4 and opens to the outer peripheral side of the syrup discharge port 3a. It has a discharge housing 5 which forms a carbonated water discharge space, and an adjusting body 9 is loosely fitted therein by using the peripheral wall of the syrup discharge port 3a as a guide. As shown in FIGS. 4 (a) to 4 (c), the structure of the adjusting body 9 has a shape corresponding to the conical shaped carbonated water discharge space formed on the discharge housing side, and a plurality of rows of carbonated water are provided on the outer peripheral surface thereof. It has a conical cylinder part 9b in which a passage groove 9a is formed, a syrup nozzle part 9c protruding from the center of the lower surface of the conical cylinder part 9b, and a protruding rib 9d formed on the bottom surface of the conical cylinder part.

On the other hand, a spout 13 is liquid-tightly fitted and mounted on the outer periphery of the discharge housing 5 while carrying the adjusting body 9 via a seal ring 10. The spout 13 is a trumpet-shaped body having a carbonated beverage mixing space 11 inside and a carbonated beverage outlet 12 on the lower surface, and a protruding rib 9d on the intermediate stepped portion.
And the adjustment body 9 is carried. Further, a flange portion and a stopper 13a projecting to the left and right are formed on the outer peripheral surface of the mounting base of the spout 13, and the spout 13 is locked and held by a spout holding mechanism 16 described below via the stopper 13a. . Here, the spout holding mechanism 16 has a spout insertion window 16b opened in the center of a U-shaped substrate 16a, and holds the spout 13 inserted in the window in a bayonet manner.
A notch groove 16c for inserting the spout-side stopper 13a is formed on the peripheral edge of b, and a tapered support pedestal 16d that engages with the stopper 13a is provided on the back surface side of the substrate 16a. The base plate 16a is attached to the main body of the carbonated beverage adjuster with a screw 1
Fixed at 7.

The operation of mixing carbonated drinks by the carbonated drink regulator with the above-mentioned configuration is the same as that of the conventional configuration shown in FIG. 5, and the syrup and carbonated water separately sent from the beverage supply valve side are spouted. After mixing inside, the spout discharges and supplies to the cup. In order to assemble the carbonated beverage adjuster, first, the adjusting body 9 is loosely inserted into the discharge housing 5, and then the spout 13 is discharged from below through the window 16b opened in the base plate 16a of the spout holding mechanism 16.
Then, the spout 13 is rotated to engage the stopper 13a with the tapered surface of the support pedestal 16d on the holding mechanism side. As a result, the spout 13 carries the adjusting body 9 and is locked and held at a predetermined position. When adjusting the mixing ratio of carbonated water, the stopper 13a is moved along the tapered surface of the support pedestal 16d by slightly rotating the spout 13 in either of the left and right directions in this assembled state. The entire spout is displaced vertically. As a result, the adjusting body 9 together with the spout 13 is vertically displaced in the discharge housing, and the gap dimension d between the inner peripheral conical surface of the discharge housing 5 and the outer peripheral surface of the conical cylindrical portion on the adjusting body side is changed.

On the other hand, by rotating the spout 13 from the above-mentioned assembled state to align the stopper 13a with the notch groove 16c on the holding mechanism side and then pulling it downward, the spout 13 and the adjusting body 9 are removed together from the discharge housing 2a. Therefore, these parts, the syrup passage 3, the carbonated water passage 4, and the like inside the discharge housing can be easily washed.

As described above, the carbonated water mainly flows through the gap between the inner peripheral conical surface of the discharge housing 5 and the outer peripheral surface of the conical cylinder portion 9b of the adjusting body 9, but the adjusting body 9 discharges the syrup of the discharge housing 5. Since it is loosely fitted and inserted in the cylindrical portion forming the outlet 3a, the inner peripheral surface of the conical cylindrical portion 9b of the adjusting body 9 and the discharge housing 5
There is a concern that carbonated water may leak through the gap between the syrup discharge port 3a and the cylindrical portion. However, in practice, as shown in FIG.
The inner peripheral surface of the conical cylindrical portion 9b and the cylindrical portion forming the syrup discharge port 3a of the discharge housing 5 can be vertically moved by sliding the adjusting body 9 on the cylindrical portion forming the syrup discharge port 3a of the discharge housing 5. Therefore, the inner peripheral surface of the conical cylindrical portion 9b of the adjusting body 9 and the syrup discharge port of the discharge housing 5 are closely contacted with each other.
Almost no gap is formed between the cylindrical portion forming 3a and carbonated water. Therefore, even if high-pressure carbonated water acts, the amount of carbonated water that leaks between the inner peripheral surface of the conical cylindrical portion 9b of the adjusting body 9 and the cylindrical portion forming the syrup discharge port 3a of the discharge housing 5 is extremely small. Or almost zero. Therefore, the amount of carbonated water that leaks between the inner peripheral surface of the conical cylindrical portion 9b of the adjusting body 9 and the cylindrical portion of the discharge housing 5 forming the syrup discharge port 3a is adjusted with the inner peripheral conical surface of the discharge housing 5. This is negligible compared to the amount of carbonated water flowing through the gap between the outer peripheral surface of the conical cylinder portion 9b of the body 9.

[Effect of device]

As described above, according to the present invention, the syrup discharge port that communicates with the syrup passage is formed in the center of the lower surface, and the conical-shaped carbonated water discharge space that opens around the syrup discharge port and that communicates with the carbonated water passage is opened. A housing, a conical cylinder part having a shape corresponding to the carbonated water discharge space, and a syrup nozzle part projecting downward from the conical cylinder part and communicating with the syrup discharge port are provided, and a play is made from below into the opening of the discharge housing. An adjusting body fitted in a fitting manner, a carbonated beverage discharge outlet opening downward, and a spout carrying the adjusting body and fitted in a liquid-tight manner to an outer peripheral portion of a discharge housing; and the spout. The carbonated beverage adjuster is assembled by a spout holding mechanism that detachably engages and supports the spout and moves the spout up and down together with the adjuster by a rotating operation. Parts assembly without the need for screws operation,
Disassembly, adjustment of carbonated water mixing ratio, and cleaning can be performed easily, and maintenance and handling can be improved.
