Abstract

PURPOSE:To provide a carbonated water manufacturing device which allows carbon dioxide gas to be stably absorbed in water through the adequate contact between water and carbon dioxide gas. CONSTITUTION:A rotary shaft 16 driven by a speed reduction motor 25 is provided in a vertical direction in a tank where carbon dioxide gas and water are introduced, and a submerged propeller 24 which pushes water downward by rotation of the shaft 16 is attached to the shaft 16. In addition, a contact member consisting of protruding pieces 17 which extend in a radial direction to an area near the inner wall of the tank 1 is provided on a part above the propeller 24 of the shaft 16. Subsequently, if the shaft 16 rotates, the propeller 24 pushes water downward in the tank 1, causing water convection to result in a change in the water level of the tank 1. Thus the chance of contact between water and carbon dioxide water increases, if water passes between the protruding pieces due to the change in a water level, and thus the efficient absorption of carbon dioxide gas takes place.

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. It is configured to mix carbon dioxide gas and water by transportation 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 a stable state by sufficiently contacting the water with the carbonated water. To do.

[0005]

In order to solve the above-mentioned problems, a carbonated water producing apparatus according to the present invention comprises a tank into which carbon dioxide gas and water are introduced, and a rotary shaft vertically provided in the tank. A propeller attached to the rotary shaft so as to be submerged in the water in the tank and pushing water downward by rotation, and a water flow generated by the rotation of the propeller, which has a large number of projecting members inside the tank. The carbon dioxide gas and the water pass through these protruding members, so that the water and the carbonated water are brought into fine contact with each other, and a contact member is provided.

[0006]

In the tank, the water pushed down by the rotation of the propeller rises due to convection, and the fluctuation of the water level caused by this causes a flow to pass between the protruding members so that the water and the carbon dioxide gas come into close contact with each other. Become.

FIG. 1 is a diagram showing an embodiment of a carbonated water producing apparatus according to the present invention. Referring to the drawings, 1 is a tank for producing carbonated water, and carbon dioxide gas is supplied under pressure from a carbon dioxide gas cylinder 4 via a carbon dioxide gas pipe 3 by opening the solenoid valve 2. 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. Further, in the tank 1, the water supply pipeline 1 is opened by opening the solenoid valve 9.
Although cold water is supplied through 0, a check valve 12 is inserted in the water supply pipe line 10 between the electromagnetic valve 9 and the water inlet 11 of the tank 1. Inside the tank 1, a set of water level sensors 1
3, 14 are provided, and when the sensor 14 detects a decrease in the water level, the solenoid valve 9 is opened, and water is supplied through the water supply pipe line 10 until the water level reaches the level of the sensor 13. .. When water and carbon dioxide are supplied in this way, layers of both are formed in the tank 1 in the vertical direction.

A deceleration motor 25 is installed in the tank 1.
The shaft 16 that is rotated by the drive of is arranged in the vertical direction. A propeller 24 that is submerged in water and pushes water downward by the rotation of the shaft 16 is attached to the shaft 16. Further, a contact member composed of a large number of projecting members 17 extending in the radial direction up to near the inner wall of the tank 1 is attached to a portion of the shaft 16 above the propeller 24. Protruding material 17
Is made of, for example, bristles or a linear material, and is brush-shaped or comb-shaped on the shaft 16.

When the shaft 16 rotates, the propeller 24 pushes the water in the tank 1 downward, so that water convection occurs and the water surface in the tank 1 fluctuates as shown in FIG. When water passes between the projecting members 17 due to the fluctuation of the water level, the chance of contact between the water and the carbonated water increases, and carbon dioxide gas is effectively absorbed. In addition, at this time, the protruding member 17 submerged in water
Since the water stirs in water, carbon dioxide can be effectively dissolved in the water. Further, the carbon dioxide gas is effectively absorbed also by the water being dispersed into fine water droplets by the rotation of the protruding member 17.

The carbonated water produced in the tank 1 in this manner is supplied through the carbonated water conduit 23 while the flow rate controller 22 adjusts the flow rate by opening the carbonated water supply valve 21. ..

FIG. 3 shows a structure in which a large number of protruding members 17 are attached as contact members to the inner wall of the tank 1 together with the shaft 16. The protruding member 17 of the shaft 16 and the protruding member 17 of the inner wall face each other. It is provided. In this case, when the shaft 16 rotates and the water level fluctuates due to convection as shown in the figure, effective contact between the water passing through and the carbonated water is mainly performed by the protruding member 17 of the inner wall, The stirring is mainly performed by the protruding member 17 of the shaft 16.

[0012]

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.
