US Patent 10190817 Refrigerator

Disclosed herein is a refrigerator which includes a carbonated water production assembly, wherein the carbonated water production assembly includes a structure in which a carbonated water container in which carbonated water is produced is installed as a production module, and a structure of a sensor which senses installation of the carbonated water container. Through this, when the carbonated water container is incorrectly installed or not installed, the carbonated water is prevented from being unintentionally produced, and thus efficiency of a carbonated water production may be improved.
