REFRIGERATOR

摘要

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.

主权项

1. A refrigerator comprising:
a main body; a carbonated water tank in which carbon dioxide and water are mixed to produce carbonated water; a carbon dioxide cylinder in which carbon dioxide is charged; a pressure regulator which adjusts a pressure of carbon dioxide discharged from the carbon dioxide cylinder and discharges the carbon dioxide; a solenoid switch valve which regulates supplying of the carbon dioxide discharged from the pressure regulator to the carbonated water tank; a connection channel which connects the pressure regulator and the solenoid switch valve; and a relief valve which is provided in the connection channel to discharge carbon dioxide in the connection channel to the atmosphere when a pressure of the carbon dioxide in the connection channel is greater than a predetermined pressure limit.
