Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carbonator for producing carbonated water used in a dispenser or a vending machine for selling cold beverages.

[0002]

2. Description of the Related Art FIG. 5 is a front view of a main part of a conventional example,
FIG. 6 shows a side view thereof. In FIGS. 5 and 6,
Reference numeral 101 is a carbonator body, 2 is a closed tank, 3 is a high-pressure water jet nozzle for introducing high-pressure water into the closed tank, and 4 is a carbon dioxide gas nozzle for introducing carbon dioxide into the closed tank. Is a water level detector, 6 is a carbonated water pipe connection port, and 7 is a safety valve.

In this structure, high-pressure water supplied from a water pump (not shown) is jetted by the high-pressure water jet nozzle 3 in order to produce carbonated water according to a command from a control device (not shown). Then, carbon dioxide gas is supplied from a carbon dioxide gas cylinder (not shown) through the carbon dioxide gas nozzle 4 so as to be sprayed onto the jetted water, and a part of the sprayed carbon dioxide gas is dissolved in the jetted water to become carbonated water. It is stored in the closed tank 2.

The carbonated water produced and stored in this way is connected to the carbonated water pipe connection port 6 which is guided from the closed tank 2 to the outside of the closed tank 2 according to a command from a control device (not shown) at the time of selling the beverage. It is supplied to a cup (not shown) through a pipe leading to it. Further, the water level detector 5 installed in the closed tank 2 detects the water level of the carbonated water and sends a signal to a control device (not shown) to give an instruction to start the production of the carbonated water from the control device. .

A safety valve 7 installed in the closed tank 2
Is used to release the abnormal pressure when the abnormal pressure in the closed tank rises, and manually releases the carbon dioxide gas in the closed tank 2 when replacing the carbon dioxide gas cylinder (not shown) or when maintaining the carbonated water system. Used to press. The amount of carbon dioxide dissolved in the carbonated water is inversely proportional to the temperature during the production of the carbonated water and increases in proportion to the pressure. Therefore, the pressure is the pressure provided between the carbon dioxide gas cylinder (not shown) and the carbon dioxide gas nozzle 4. Controlled by a control valve (not shown) (approximately 5 kg
/ Cm ² ) and the temperature is maintained at a constant temperature (about 4 ° C.) by immersing the closed tank 2 in a cooling water tank (not shown).

[0006]

A carbonizer for producing carbonated water used in a dispenser for selling cold beverages or a vending machine is installed in a cooling water tank to keep its temperature constant. In the vending machine, equipment that requires frequent operations such as a beverage raw material storage device and a cup mechanism occupy a convenient location for handling, so the cooling water tank is often not located at a location convenient for maintenance. For this reason, when manually operating the safety valve of the carbonator, the operator is forced to work in a difficult posture.In some cases, a device that allows the equipment around the carbonator to be moved is installed in advance for convenient maintenance. Need to be measured. Therefore, there is a problem that the cost of the dispenser or the vending machine increases.

It is an object of the present invention to provide a carbonator which facilitates manual operation of the safety valve of the carbonator by providing the safety valve at a location remote from the carbonator.

[0008]

According to a first aspect of the present invention, a hermetically sealed tank, a carbon dioxide gas nozzle for supplying high pressure carbon dioxide gas to the hermetically sealed tank, and a high pressure for ejecting high pressure water to facilitate melting of carbon dioxide gas are provided. A carbonator equipped with a water jet nozzle, a pipe that melts carbon dioxide gas to lead the carbonated water stored in the sealed tank to the outside of the sealed tank, and a safety valve that releases the abnormal pressure when the abnormal pressure rises in the sealed tank. In the above, the safety valve is a carbonator provided in the closed tank via a pipe connected to the closed tank.

According to a second aspect of the present invention, a closed tank, a carbon dioxide gas nozzle for supplying high-pressure carbon dioxide gas to the closed tank, a high-pressure water jet nozzle for jetting high-pressure water to facilitate the dissolution of carbon dioxide gas, and carbon dioxide Connected to a closed tank in a carbonator equipped with a pipe that melts gas and leads carbonated water stored in the closed tank to the outside of the closed tank, and a safety valve that releases abnormal pressure when abnormal pressure rises in the closed tank A manual pressure release valve is used as the carbonator provided in the sealed tank through the pipe.

[0010]

By providing a pipe connection port in the closed tank and connecting the valve that can be opened and closed manually with the pipe connection port with a pipe, the installation location of the valve that can be opened and closed manually can be freely selected.

1 is a front view of a main portion of an embodiment of the present invention, and FIG. 2 is a side view thereof. In FIGS. 1 and 2, members given the same reference numerals as those in the conventional example have substantially the same functions, and therefore description thereof will be omitted. This Figure 1
In FIG. 2, 1 is a carbonator body, 2 is a closed tank, 3 is a high-pressure water jet nozzle, 4 is a carbon dioxide gas nozzle, 5 is a water level detector, 6 is a carbonated water pipe connection port, and 7 is a safety valve. Reference numeral 8 indicates a connection port of the pipe. 1 is different from the conventional example in that a closed tank 2 is provided with a connection port 8 for a pipe 11 and a pipe 11 is connected from the connection port 8 to the safety valve 7, and the safety valve 7 is installed at a place away from the closed tank 2. This is the point that I was able to do.

FIG. 3 shows a front view of a main part of another embodiment of the present invention, and FIG. 4 shows a side view thereof. 3 and 4 are different from the conventional example in that the closed tank 2 is provided with a connection port 9 for the pipe 12 and the pipe 1 is connected from the connection port 9 to the manual pressure release valve 10.
2 is connected, and the manual pressure relief valve 10 can be installed separately from the safety valve 7 at a location apart from the closed tank 2.

[0013]

According to the present invention, since the safety valve or the manual pressure release valve can be installed separately from the carbonator, there is an effect that the operation of releasing the pressure of the carbonator is facilitated.
