CONSTITUTION:A contact member consisting of a large number of protruding materials 17 is provided in a tank 1 into which carbon dioxide and water are introduced and water and carbon dioxide are finely brought into contact with each other by passing both of them through the protruding materials 17 to effectively perform the absorption of carbon dioxide.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus having a tank into which carbon dioxide gas and water are introduced and producing carbonated water by contacting carbon dioxide gas and water in the tank.

[0002]

As such an apparatus for producing carbonated water, there is an apparatus as disclosed in, for example, Japanese Patent Application Laid-Open No. 61-64320, in which carbon dioxide gas is converted into water in the upper and lower layers of carbon dioxide gas and water in a tank. By transporting, carbon dioxide gas and water are mixed to generate carbonated water.

[0003]

However, since the above-mentioned prior art has a structure in which carbon dioxide gas and water are simply mixed, absorption of carbon dioxide gas is insufficient and gas separation is easy when contained in the mouth, so-called delicious carbonated water. Has the drawback that is not generated. Therefore, the present invention provides a carbonated water producing apparatus capable of producing delicious carbonated water by allowing the carbonated water to be absorbed in water in a stable state by sufficiently contacting the water with the carbonated water. is there.

[0004]

In order to solve the above problems, a carbonated water production apparatus according to the present invention has a tank into which carbon dioxide gas and water are introduced, and a large number of projecting members inside the tank. Therefore, the carbon dioxide gas and the water pass between the projecting members so that the water and the carbonated water are brought into fine contact with each other.

[0005]

In the tank, the carbonated water is absorbed by water as the carbon dioxide gas and the water pass between the projecting members, but the provision of the projecting member only increases the contact area between the water and the carbonated water. Since water and carbonated water contact each other little by little between the protruding members, stable absorption of carbon dioxide gas is performed.

1 is a diagram showing an embodiment of a carbonated water producing apparatus according to the present invention. Referring to FIG. 1, reference numeral 1 is a tank for producing carbonated water, and by opening the solenoid valve 2, carbon dioxide gas is supplied under pressure from a carbon dioxide gas cylinder 4 via a carbon dioxide gas pipe 3. The carbon dioxide line 3 is provided with a pressure regulator 5 and a check valve 6. A pressure release pipe 20 is connected between the carbon dioxide gas inlet 7 of the tank 1 and the solenoid valve 2 via another solenoid valve 8. Also,
Cold water is supplied to the tank 1 through the water supply line 10 by opening the solenoid valve 9, but a check valve is provided in the water supply line 10 between the solenoid valve 9 and the water inlet 11 of the tank 1. 12
Is inserted. A set of water level sensors 13 and 14 is provided inside the tank 1, and when the sensor 14 detects a decrease in the water level, the solenoid valve 9 is opened and the water supply pipeline 10 is opened until the water level reaches the level of the sensor 14. Water is supplied through. When water and carbon dioxide are supplied in this way, layers of both are formed in the tank 1 in the vertical direction.

The stirring device 15 has a plurality of paddles 24 for stirring water and carbon dioxide on the stirring shaft 16. The stirring shaft 16 is a deceleration motor 2 provided outside the tank 1.
It rotates by the drive of 5, but this rotation causes the paddle 24
The stirring shaft 16 is arranged in the vicinity of the interface 18 between both layers of water and carbonated water so as to be substantially parallel to the interface 18 so as to repeatedly appear and disappear from the interface 18.

A large number of projecting members 17 are attached to the stirring shaft 16 in the radial direction. The protruding member 17 is made of, for example, bristles or a linear material, and is planted on the stirring shaft 16 in a brush shape or a comb shape. Similar to the paddle 24, this protruding member 17 is also attached to the stirring shaft 16 so as to repeatedly project and retract from the interface 18 by the rotation of the stirring shaft 16. Therefore, when the stirring shaft 16 rotates, the paddle 24 mixes the water in the tank 1 with the carbon dioxide gas, and the projecting material 17 alternately passes through the water and the carbon dioxide gas to allow the carbon dioxide gas and the water to project. Due to the passage between 17, the chances of contact between water and carbonated water are increased, and carbon dioxide gas is effectively absorbed. The carbonated water produced in the tank 1 is supplied through the carbonated water conduit 23 while the carbonated water supply valve 21 is opened to adjust the flow rate by the flow rate controller 22.

FIG. 2 shows an embodiment in which only the projecting member 17 is attached to the stirring shaft 16, and the projecting member 17 has both a mixing action of water and carbon dioxide and a high-density contact action of both. It is done at the same time. 1 and 2 described above, the protrusion member 17 is attached to the stirring shaft 16 to form a contact member, but in the embodiment of FIG. 3, a large number of protrusion members 17 are attached to the inner wall of the tank 1. 3 shows a structure of a contact member. In this case, a paddle 24 is attached to the agitation shaft 16, and the flow of water and carbon dioxide gas generated by the drive of the agitation device 15 passes between the projecting members 17 so that water and carbonated water come into contact with each other. Opportunities are increased and carbon dioxide is effectively absorbed.

[0010]

According to the present invention, carbonated water containing carbon dioxide in a stable state can be produced in order to bring water into contact with carbon dioxide through a contact member having a large number of protruding members.
