Abstract: A refrigerator having a carbonated water production device, according to one concept of the present invention, comprises: a pressure regulator for adjusting and emitting the pressure of carbon dioxide emitted from a carbon dioxide cylinder; a solenoid switch valve for controlling the supply of the carbon dioxide discharged from the pressure regulator to a carbonated water tank; a connection channel for connecting the pressure regulator and the solenoid switch valve; and a relief valve arranged in the connection channel so as to discharge the carbon dioxide of the connection channel to the atmosphere if the pressure of the carbon dioxide of the connection channel is greater than a predetermined pressure limit. Thus, the pressure of the carbon dioxide of the connection channel is capable of being maintained at a predetermined pressure limit or less, and solenoid malfunction can be prevented so as to improve reliability and stability of a system.
