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.

[0002]

2. Description of the Related Art Conventionally, in carbonated water producing apparatuses for cup benders and dispensers, Japanese Utility Model Application Laid-Open No.
As disclosed in Japanese Patent Application Laid-Open Publication No. H10-260, carbonated water is generated by ejecting high-pressure water and carbon dioxide gas directly from a water nozzle and a gas nozzle into a closed tank.

[0003] In addition to the production method described in the above publication, in which high-pressure water and carbon dioxide gas are directly mixed and mixed to produce carbonated water, there is also the following method.

[0004] That is, a cup is mounted on the upper part of the carbonator tank, and after filling the tank with carbon dioxide gas at a constant pressure, water is injected into the cup from the upper part of the tank to mix water and carbon dioxide gas. It is a carbonated water production method.

[0005]

However, according to the above method, when water is jetted into the cup, the water jetted vigorously overflows from the upper portion of the cup, and the water is injected into the lower portion of the tank without absorbing sufficient carbon dioxide gas. And could not make good carbonated water.

[0006] The present invention has been made in view of the above points, and it is an object of the present invention to provide a carbonator suitable for providing a delicious carbonated beverage in which carbon dioxide gas is sufficiently dissolved.

[0007]

In order to achieve the above object, the present invention provides a carbonator which mixes carbon dioxide gas and water supplied under pressure to produce carbonated water. A container in a carbon dioxide atmosphere similar to that in the tank, a water introduction part for introducing water by spraying or spraying from the upper part of the container into the container, and any one of the side and bottom surfaces or the side and bottom surfaces of the container And a carbonator having a structure in which a wall surface for preventing overflow of water introduced into the container and forming a wall for circulating water in the container is formed at an upper portion of the container. It was done.

[0008]

The water is supplied into a container separately provided in the carbonator tank and having an upper portion covered with a wall. Water is sprayed or sprayed and enters vigorously and mixes with the carbon dioxide filled in the container.However, the water is circulated in the almost closed space inside the container and does not escape outside, so the carbon dioxide Can be blended into.

The generated carbonated water flows out of the outlet hole on the side of the container and accumulates in the carbonator tank. After the supply of water is stopped, the carbonated water remaining in the container also flows out of the outlet at the bottom of the container.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a carbonator as a carbonated water producing apparatus according to the present invention. In FIG. 1, reference numeral 1 denotes a carbonator tank (hereinafter, referred to as a tank). In the tank 1, a carbon dioxide gas inlet 2 for injecting carbon dioxide (CO ₂ ) into the tank 1, A relief valve 3 is provided for discharging gas such as air or nitrogen or oxygen accumulated in the tank 1 to the outside of the tank 1. Further, a sign phone tube 4 is provided to extend upward from a lower part in the tank 1 to supply the carbonated water A manufactured in the tank 1, and the level of the carbonated water A formed in the tank 1 is adjusted. A water level sensor 5 for detection is provided. Reference numeral 6 denotes a water supply pipe extending through the center of the upper surface 1a of the tank 1 into the tank 1.
A nozzle portion 7 having a spray nozzle or a small hole for spraying or spraying water is formed at the tip.
8 is a hole 10 through which the water supply pipe 6 is inserted.
The container is formed at the center of the water supply pipe 6 and pressurized water is injected into a carbon dioxide gas atmosphere filling the inside thereof, thereby mixing the carbon dioxide gas and the water to generate the carbonated water. 1, support legs 11 in the upper part,
11 and supported in a hanging state. Here, the container 8 is in a suitable shape in which the upper part is covered with the wall surface 10, and the inside of the container is a substantially closed space. Therefore, even if water enters the container vigorously, it does not overflow to the outside. The water circulates in the container, so that the carbon dioxide gas is well dissolved in the water. The hole 9 and the water supply pipe 6
Constitutes an inlet for water. And
The hole 9 through which the water supply pipe 6 passes has a diameter of the water supply pipe 6.
Since the diameter is larger, the gap between the water supply pipe 6 and the hole 9 serves as an inlet for carbon dioxide gas. As shown in the figure, a plurality of outflow holes 13 through which the carbonated water generated in the container 8 flows out are formed on the side surface of the container 8. A similar outflow hole 13 is provided at substantially the center of the bottom of the container 8, and the carbonated water remaining in the container 8 is discharged from the outflow hole 13.

The nozzle 7 of the water supply pipe 6 is connected to a container 8
It is located at the center of the inside to make the mixing of water and carbon dioxide most effective.

With the above structure, the carbon dioxide gas inlet 2
A constant pressure in tank 1 with carbon dioxide gas from tank 1
The carbon dioxide gas remaining inside is released by the relief valve 3
Discharge outside tank 1. Next, water is supplied from the water supply pipe 6. The water is sprayed or the tip nozzle part 7 having a small hole
It sprays or sprays more and mixes with the carbon dioxide gas filled in the container 8. At this time, unlike the conventional cup with the upper opening, the container 8 is a substantially closed container whose upper surface is closed, so that the water jetted into the container 8 circulates through the container 8 as in the conventional case. Since the water does not flow out of the container 8 with the force of the jet, the water is well mixed with the carbon dioxide gas.

When a certain amount of the carbonated water thus generated flows into the container 8, the carbonated water flows out of the outlet hole 12 on the side of the container and accumulates in the tank 1. When the water level of the carbonated water A produced in the tank 1 reaches a certain level, it is detected by the water level sensor 5 and the supply of water is stopped. The carbonated water remaining in the container 8 with the water level lowered from the outflow hole 12 flows down into the tank 1 through the outflow hole 13 at the lower part of the cup, and all the carbonated water A accumulates in the tank 1.

In this manner, carbonated water A having a high gas volume can be produced. The carbonated water A in the tank 1 is taken out through the siphon gas tube 4. Without extending the water supply pipe 6 into the container 8, as shown in FIG. 4, the water supply pipe has a short length so that the hole 9 </ b> A formed on the upper surface 10 of the container 8 and the nozzle 7 correspond to each other. 6 may be provided on the upper surface 1 a of the tank 1. In this case as well, although the upper part of the container 8 is opened by the hole 9a, the water does not overflow to the outside of the container 8 because it is almost in a closed state. A well-mixed carbonated water is produced. Here, the hole 9A and the short length water supply pipe 6
Constitutes a water inlet.

Further, as shown in FIG.
It is also possible to directly mount and fix the container 8 on the upper surface of the carbonator tank 1 without using the container 1. In this case, the carbonator body is a container that also serves as the upper wall of the container 8. Therefore, only by providing the inlet of the carbon dioxide gas and the water supply port on the upper wall portion of the carbonator tank, the carbon dioxide gas and the water can be introduced, and the overall configuration is further simplified.

In this case, when a large amount of nitrogen or oxygen is contained in the carbon dioxide layer in the upper part of the container 8, a hole 15 is provided for letting the gas out of the tank 1. Hole 1
The gas once entered into the tank 1 by 5 is discharged out of the tank 1 by the relief valve 3.

[0017]

As described above, according to the present invention, the container provided in the carbonator tank for mixing carbon dioxide gas and water has an upper wall-like wall and a closed inner wall. Since the container has a structure with a space, it is surely prevented that the water injected and injected into the container overflows from the upper part with the force at the time of the ejection as in the case of a conventional container having an open top. . Further, since the water circulates in the substantially closed container, the mixing with the carbon dioxide gas is sufficiently performed, so that good carbonated water having a high gas volume can be generated. Further, such a carbonator capable of producing high-quality carbonated water can be provided as a means that can be achieved by employing a container that is not open at the top and that is simple and inexpensive.
