A solenoid valve 101 is provided at the tip of the pre-chilled water supply pipe 28, and on the downstream side of this solenoid valve 101, cold water and carbon dioxide gas supplied from the carbon dioxide gas cylinder 21 via the gas pipe 100 are mixed to produce carbonated water. An injector 33 is provided for making.

When the pressure inside the gas-liquid mixing tank 15 becomes higher than necessary, the back pressure of the injector 33 increases and the degree of absorption of carbon dioxide gas into the cold water decreases. A signal from a pressure 31 (not shown) provided at the pipe acts to stop or reduce the supply of cold water.

As shown in FIG. 6, the injector 33 is a fuel line for squeezing and spouting the flow of cold water (0 to 6°C) pressurized to a predetermined pressure (6 to 16/(g/aG)) by the pump 29.

In addition, the cold water pressurizing pump 29 operates under the predetermined pressure (6 to 16 phantom/cjlG) at 1 to 5! J/min. Since the nozzle 50 is formed in a screw-like shape, the jet water flows out from the tip of the nozzle in a swirling manner, thereby significantly improving the mixing effect.

The carbonated water produced by the injector 33 is sent to the gas-liquid mixing tank 15 via the pipe 31, where it is temporarily stored and the mixture of carbon dioxide gas and cold water is stabilized. The gas-liquid mixing tank 15 has a capacity of 5 to 10 depending on the pump discharge pressure.

In this way, if a thicker nozzle is provided in place of the throttle valve 42 or 43 in the chilled water system and the shape of this nozzle is configured as described above, turbulence will be caused (the I2 valve is likely to cause turbulence). ), the flow rate can be adjusted and the flow rate can be slowed down without effectively separating carbon dioxide gas from carbonated water. Therefore, the outflow speed of carbonated water flowing out from the spout becomes slow, and the falling speed into the spout C becomes 1, so that the splashing of carbonated water inside the spout is reduced. As a result, the release of carbon dioxide gas dissolved in the carbonated water within the cup can be effectively suppressed. Also, the gas-liquid mixing tank 1 when the solenoid valve 38.
The pressure drop within 5 is reduced.

As a result, the carbon dioxide gas that is being dissolved in the tank 15 is diffused again into the gap in the upper part of the tank, thereby preventing a decrease in the carbon dioxide concentration in the cold water. For example, the diameter of the constricted part 62 of the thick tip nozzle 60 is 2 layers, and the length is 15! The length of the MR1 enlarged part 63 is 60
