DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carbonated beverage dispensing valve mounted on a beverage dispenser.

[0002]

2. Description of the Related Art A carbonated beverage dispensing valve described above mixes carbonated water and a beverage concentrate (syrup, liquor, etc.) separately pumped through a beverage line in a beverage dispenser, and discharges the mixture to a cup. A carbonated beverage dispensing valve having the structure shown in FIGS. 3 (a) and 3 (b) is disclosed in Japanese Patent Laid-Open No. 10-19439.
No. 3 discloses this.

In FIG. 3, reference numeral 1 denotes a valve main body, 2 denotes a valve opening / closing operation lever, and 3 denotes a spout nozzle having a beverage discharge port opened downward. Here, the valve body 1
The carbonated water supply valve 4, the beverage undiluted supply valve 5, and the carbonated water flowing around the carbonated water supply valve 5 in the surrounding area surrounding the beverage undiluted supply pipe 6 drawn straight forward from the beverage undiluted supply valve 4. A cylindrical beverage discharge head 7 defining a discharge passage,
The spout nozzle 3 is connected to the beverage discharge head 7. On the other hand, the opening / closing operation lever 2 is arranged such that the upper end thereof is connected to the carbonated water supply valve 4 and the undiluted beverage supply valve 5 so that the operation side hangs behind the spout nozzle 3. The contact causes the carbonated water supply valve 4 and the beverage stock solution supply valve 5 to open.

[0004] In the carbonated water passage inside the beverage discharge head 7, a resistance component 8 for reducing the pressure of the carbonated water fed through the carbonated water supply valve 5, and the reduced pressure carbonated water for the beverage of the spout nozzle 3. A rectification component 9 that is distributed and supplied from the surroundings toward the discharge port is provided. Here, the resistance component 8 shown in FIG. 3 is inserted as a cylindrical cone into the straight beverage supply pipe 6 and mounted between the outer peripheral surface of the cone and the inner peripheral wall surface of the beverage discharge head 7 at this mounting position. Gap remaining in the
Alternatively, a large number of slit-like narrow grooves formed on the outer peripheral surface of the cone are made to function as a pressure reducing passage for carbonated water. The rectifying component 9 is formed by dispersing a plurality of U-shaped grooves on an outer peripheral edge of the rectifying component 9 using a disk as a base.

In this configuration, when the beverage is supplied, the cup is held in hand and pressed against the opening / closing operation lever 2 of the valve from the front, the beverage stock solution supply valve 4 and the carbonated water supply valve 5 are opened, and the beverage is fed from the beverage line. The undiluted beverage flows through the supply pipe 6, and the carbonated water flows down to the spout nozzle 3 through the resistance component 8 and the rectifying component 9 built in the beverage discharge head 7, where the undiluted beverage and carbonated water are mixed and cupped. And supplied to the

[0006] In this case, the carbonated water pumped from the carbonator under the pressure of carbon dioxide gas gradually flows through the pressure reducing passage between the cylindrical cone as the resistance component 8 and the inner wall surface of the discharge head 7. Thus, when the carbonated water is discharged to the spout nozzle 3, the carbon dioxide dissolved in the carbonated water is separated and the gas volume of the carbonated water is prevented from being reduced.

[0007]

However, the above-described carbonated beverage dispensing valve of the conventional configuration has the following problems in terms of the function of reducing the pressure of the carbonated water and handling. That is, (1) In the configuration of FIG. 3, a gap or cone formed between the outer peripheral surface of the cylindrical cone (resistive component 8) provided inside the carbonated passage of the beverage discharge head 7 and the inner wall surface of the beverage discharge head 7 The slit-shaped narrow groove formed on the outer peripheral surface of the container is used to reduce the pressure of the carbonated water fed by using the pressure reducing passage (throttle passage) of the carbonated water, and the cylindrical cone is suspended at the center of the beverage discharge head 7. The interior is set by inserting it into a straight undiluted beverage supply pipe 6 that extends.

In this case, the position of the cylindrical cone varies in the assembled state of the carbonated beverage discharge valve, and the beverage discharge head 7
When the pressure is deviated, the width of the pressure reducing passage changes, and the pressure reducing characteristic changes. As a result, the gas volume loss of carbonated water discharged to the spout nozzle 3 increases. Performance is not stable.
Therefore, in order to exhibit the required decompression performance with the conventional structure, high dimensional accuracy is required in the production and management of the cylindrical cone (resistance component 8) and the beverage discharge head 7, and the price of the component increases. .

(2) Further, the carbonated beverage discharge valve is designed to frequently clean the inside of the beverage discharge head 7 from the viewpoint of hygiene management. It is necessary that components such as the rectifying component 9 can be easily attached and detached. In this respect, in the conventional structure, since the cylindrical cone of the resistance component is fitted in the inner wall surface of the beverage discharge head 7 so as to be in close contact with the inner surface of the beverage discharge head 7, it is difficult to remove the cylindrical cone. There is a problem of sex.

[0010] The present invention has been made in view of the above points, and an object of the present invention is to solve the above-mentioned problems, and to stabilize a resistance component contained in a beverage discharge head without being affected by variations in the mounting position. An object of the present invention is to provide a carbonated beverage dispensing valve improved so that gas volume loss can be reduced by exerting decompression performance of carbonated water, and resistance components can be easily attached and detached.

[0011]

According to the present invention, there is provided, in accordance with the present invention, a mixture of carbonated water and an undiluted beverage which have been separately pumped through a beverage line, and dispensing and supplying the mixture to a cup. An outlet valve that surrounds the carbonated water supply valve, the beverage concentrate supply valve, and the straight beverage concentrate supply pipe drawn out from the beverage concentrate supply valve, and defines a carbonated water discharge passage around the periphery thereof to communicate with the carbonated water supply valve. Consisting of an assembly of a valve body composed of a beverage discharge head, a spout nozzle coupled to the beverage discharge head, and a valve opening / closing operation lever,
And, in a carbonated water passage in the beverage discharge head, a resistance component for decompression and a rectification component are provided in series,
The resistance component has a structure in which a plurality of throttle holes are dispersed and perforated using a cylindrical block as a base, and the cylindrical block is inserted into a beverage stock solution supply pipe and is housed in a carbonated water passage (claim 1). The block is provided with an O-ring on its outer peripheral surface, and the O-ring is brought into contact with the inner wall surface of the beverage discharge head to internally set the resistance component at a fixed position in the carbonated water passage (claim 2).

In the above structure, the pressure reducing passage of the carbonated water is preliminarily dispersed and perforated in the cylindrical block of the resistance component as a throttle hole. Even if there is a variation in the mounting position, the decompression path of the carbonated water is not affected by this, and thus a stable decompression performance can always be exhibited.

Further, an O-ring is mounted on the peripheral surface of the cylindrical block of the resistance component, and the O-ring is brought into contact with the inner wall surface of the discharge head at a position inside the beverage discharge head to seal the same. There is no leakage of water by-pass, and attachment / detachment to / from the beverage discharge head can be easily performed, thereby improving maintainability during cleaning.

In the drawings of the embodiment, members corresponding to those in FIG. That is, the illustrated embodiment is basically the same as the structure of FIG. 3, but the pressure reducing resistance component 8 built in the beverage discharge head 7 has a structure as shown in FIGS. 2 (a) and 2 (b). That is, the resistance component 8 has a ring-shaped cylindrical block 8a as a base, and a plurality of throttle holes 8b penetrating the block in the axial direction are formed by being distributed in the circumferential direction. Further, an O-ring 10 is mounted on the outer periphery of the cylindrical block 8a. Here, the outer diameter of the cylindrical block 8a is slightly smaller than the inner diameter of the beverage discharge head 7, and the inner diameter is designed and manufactured according to the diameter of the undiluted beverage supply pipe 6.

The throttle hole 8b functions as a decompression passage for carbonated water. The number of the throttle holes 8a and the diameter of the throttle hole 8b are determined in accordance with the length of the hole corresponding to the thickness of the cylindrical block 8a. The pressure difference before and after the carbonated water passing through is set so as to provide an effective passage resistance in suppressing the gas volume loss. When the resistance component 8 having such a configuration is set inside the beverage discharge head 7, the gap between the outer peripheral surface of the cylindrical block 8 a and the inner peripheral wall surface of the discharge head is O-ring 10.

Although not shown, the gap between the inner peripheral surface of the cylindrical block 8a and the undiluted beverage supply pipe 6 may be replaced with the outer periphery of the undiluted beverage supply pipe 6 or the inner periphery of the cylindrical block 8a as necessary. Attach an O-ring to the surface to seal.

In the carbonated beverage dispensing valve having the above configuration, the carbonated water pumped through the carbonated water supply valve 5 is:
In the process of flowing through the carbonated water passage of the beverage discharge head 7, it flows through the restriction hole 8 b of the resistance component 8, and at that time, the restriction hole 8 b
The pressure of the carbonated water is reduced by the resistance. As a result, it is possible to prevent the carbon dioxide gas from being separated from the carbonated water when discharged to the spout nozzle 3 as described in FIG.

In addition, even if the resistance component 8 internally set in the beverage discharge head 7 is displaced and somewhat eccentric in the assembled state of the carbonated beverage discharge valve, the throttle hole 8b drilled in the cylindrical block 8a has this effect. It can exhibit stable decompression performance without receiving. In addition, since the O-ring 10 is mounted on the outer periphery of the cylindrical block 8a to seal the gap between the cylindrical block 8a and the discharge head 7, leakage of carbonated water bypassing this gap can be reliably prevented.
The resistance component 8 can be easily attached and detached even during maintenance such as cleaning the inside of the device.

The cylindrical block is penetrated into the undiluted beverage supply pipe to be housed in the carbonated water passage, and the cylindrical block is provided with an O.D.
A ring is mounted, and the O-ring is brought into contact with the inner wall surface of the beverage discharge head to internally set the resistance component in a fixed position in the carbonated water passage. Even if the mounting position is uneven in the assembled state set inside the head, the resistance parts always exhibit stable decompression performance without being affected by the influence and the gas volume of carbonated water discharged and supplied to the cup decreases Can be effectively suppressed. In addition, an O-ring is attached to the peripheral surface of the cylindrical block of the resistance component, and the O-ring is brought into contact with the inner wall surface of the discharge head at the interior position of the beverage discharge head to seal it, so that unnecessary carbonated water can be bypassed. It is possible to provide a carbonated beverage dispensing valve excellent in function and handling, such as no leakage and easy attachment and detachment to the beverage discharge head.
