APPARATUS FOR PRODUCING CARBONATED WATER

摘要

The present invention relates to an apparatus for producing carbonated water for drinking which is installed on a water purification line of a refrigerator or the like to produce carbonated water by contact between carbon dioxide and water. The apparatus for producing carbonated water for drinking mounts a raw water source and a gas tank for supplying raw water and carbon dioxide and a mixer on a carbonated water tank in which carbonated water is produced, has a structure of the mixer where a raw water line connected to the raw water source and a gas injection line connected to the gas tank are connected to a supply line, mounts a main orifice on the supply line, mounts an auxiliary orifice of a flow relatively smaller than the main orifice of the supply line on the gas injection line to generate a negative pressure when the carbon dioxide is injected into the supply line to mix the carbon dioxide and the raw water to inject the mixture of the carbon dioxide and the raw water, allows first dissolution during the injection process to dissolve a certain amount of the carbon dioxide, and then supplies the mixture to the carbonated water tank to produce carbonated water to reduce carbonated water producing time.
