Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drink supply device.

[0002]

2. Description of the Related Art Draft beer sold in taverns, etc. is generally filled in tanks (beer barrels made of aluminum etc.) and shipped to each store at the time of factory shipment. A drink dispenser is needed to pour into. This drink supply device includes the tank, a hose having a connection plug detachably attached to the tank, and a dispenser connected to the other end of the hose for injecting and stopping a tank or the like. (Generally referred to as a "dispenser" or "raw server" with a cooling device).

In addition to the above-mentioned draft beer hose, a gas hose connected to a cylinder filled with high pressure carbon dioxide gas is connected to the plug. When the plug is connected to the tank, carbon dioxide automatically enters the tank. The gas is pumped,
Draft beer in the tank is always pushed out to the dispenser.

[0004]

Even if the inside of the tank is emptied, while the hose or the like is filled with draft beer, the state in which draft beer is vigorously discharged by the pressure of carbon dioxide gas continues if the dispenser is opened. However, once the carbon dioxide gas reaches the dispenser, the foamed beer scatters all over the spout, as if a small explosion had occurred at the outlet of the dispenser.
In addition, along with this, even the draft beer in the jug, which had been dispensed under the dispenser, spatters all over and wets the worker's clothes, and the draft beer in the jug is wasted (there is too much foam). There is a drawback that the commercial value is lost).

Further, since the foamed draft beer remains in the hoses and plugs, when the tank is replaced with a new one, it is necessary to wash away the foam by flushing it with subsequent draft beer. About 500 cc of draft beer was wasted. The present invention has been made in view of the above circumstances, and not only can prevent the drink filled in the tank from being wasted, but also the drink supply that can speed up the replacement of the tank. The purpose is to provide a device.

[0006]

In order to achieve the above object, the present invention takes the following technical means. That is, the present invention provides a drink supply device in which a tank filled with a drink under pressure is connected to a dispenser via a hose equipped with a detachable connecting plug, and between the plug and the hose. An explosion-proof device is provided, and inside this explosion-proof device, there is a drink passage extending from the lower outlet to the upper inlet, and there is no drink in the drink passage when the drink is full. It is characterized in that a moving valve element that closes the outlet in a state is inserted.

[0007]

According to the present invention, when the drink in the tank is exhausted and the drink passage of the explosion-proof device is also emptied through the plug, the movable valve body floating in the drink until then descends in the drink passage. , The outlet of the drink passage comes to be blocked. Therefore, high-pressure gas such as carbon dioxide gas is not fed to the discharger.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1 as a whole structure of a drink supply device 1 according to the present invention, in this drink supply device 1, a tank 2 filled with draft beer under pressure and a discharge for operating injection / stop to a jug 7 are discharged. In the hose 3 connecting to the container 4, an explosion-proof device 5 is provided between a hose end 3a on the tank 2 side and a plug 30 for connecting to the tank 2. In addition, a cooling device 41 is attached to the discharger 4. Further, to the tank 2, a carbon dioxide cylinder 9 is connected to the plug 30 by a gas hose 8.

As shown in FIG. 2, the plug 30 is provided with a lower protruding pipe 31, and when the plug 30 is connected to the tank 2, the lower protruding pipe 31 is connected to the mouth valve portion 2 of the tank 2.
1 pushes down the lift valve 22 provided in 1 against the spring force,
Ascending channel 32 and tank 2 formed inside the plug 30
It has a structure in which it automatically communicates with the suction pipe 23 which is suspended and held inside. The explosion-proof device 5 described above has a plug 30.
The pipe 6 is connected to the ascending flow path 32 and is connected to the plug 30. If the pipe 6 is made rigid, it is convenient for maintaining the posture of the explosion-proof device 5. An annular vent passage 33 communicating with the gas hose 8 is formed in the plug 30, and the annular vent passage 33 is connected to the tank 2 when the air pressure valve 2 provided in the mouth valve portion 21 is connected.
It conforms to 4. The air pressure valve 24 is automatically pushed and opened by the pressure of carbon dioxide gas by opening a valve (not shown) on the cylinder 9 side.

As shown in FIGS. 3 to 5, the explosion-proof device 5 is used.
A drink passage 51 is formed in the inside of the container so that the drink passage 51 is oriented in the up-down direction. In the drink passage 51, a movable valve body 52 made of resin capable of floating in draft beer is vertically movably inserted. An outlet 54 is provided in the lower portion of the drink passage 51, and an inlet 55 is provided in the inner wall of the upper portion thereof.
The outlet 54 is connected to the hose 3 connected to the discharger 4 described above, and the inlet 55 is connected to the pipe 6 connected to the plug 30 described above. In addition, a bypass path 56 that connects the upper end of the drink path 51 and the outlet side of the outlet 54 is provided, and the bypass path 56 is joined to the outlet side of the outlet 54. A passage switching valve 53 that is rotatable around a horizontal axis is provided.
The passage switching valve 53 is normally in a state of closing the bypass passage 56.

In the beverage supply device 1 of the present invention thus configured, the plug 30 is connected to the tank 2,
Carbon dioxide is pumped into the tank 2, and draft beer in the tank 2 is pushed out from the suction pipe 23, the plug 30, and the pipe 6 to the hose 3 to the discharger 4 through the explosion-proof device 5. Therefore, the draft beer can be poured into the jug 7 at any time by opening the dispenser 4. When the tank 2 becomes empty and there is no draft beer sent to the explosion-proof device 5,
In the drink passage 51, the moving valve body 52 floating on the draft beer up to that point descends and closes the outlet 54. This closed state is backed up by the pressure of carbon dioxide. Therefore, after that, carbon dioxide does not reach the hose 3 and the discharger 4, and even if the discharger 4 is opened, a small explosion does not occur at the outlet thereof. After the tank 2 is replaced with a new one, the passage switching valve 53 of the explosion-proof device 5 is operated so that the outflow port 54 and the bypass line 56 communicate with each other, and the draft beer newly fed from the inflow port 55 is used. Moving valve body 5
2 is pushed up from the outlet side of the outflow port 54.
Then, the passage switching valve 53 is returned to the original state.

In the present invention, the drink is not limited to draft beer. Further, the passage switching valve 53 and the like can be changed to another structure, and the explosion-proof device 5 and the plug 30 can be fixed by the connecting plate 57 as shown in FIG.

[0013]

The present invention has the above-mentioned structure, and when the drink in the tank is exhausted, the moving valve body closes the outlet of the drink passage in the explosion-proof device. After that, high-pressure gas such as carbon dioxide gas is not fed to the discharger. Therefore, even if the discharge device is opened in this state, a small explosion does not occur at the outlet. Therefore, there is no need to waste the drink in the jug that had been dispensed under the dispenser, to foam the drink remaining in the hose, or to need a drink to wash it away. , As a whole, waste of drinks can be saved. Also,
As described above, since there is no small explosion, the clothes of the worker are naturally prevented from getting wet, and since there is no need to wash bubbles in the hose, there is an advantage that the tank can be replaced quickly.
