Refrigerator and method of controlling the same

摘要

Provided is a refrigerator including: a carbonated water tank in which carbonated water is stored; a water tank supplying filtered water to the carbonated water tank; a carbon dioxide cylinder supplying carbon dioxide to the carbonated water tank; and a controller, if the water level of carbonated water sensed by a water level sensor is less than or equal to a predetermined minimum water level, supplying the filtered water to the carbonated water tank, and if supply of the filtered water is completed, supplying the carbon dioxide to the carbonated water tank so as to produce the carbonated water. If it is expected that the storage amount of the carbonated water is reduced or the user won't use the carbonated water for a while, carbonated water is automatically produced so that the user is not required to wait while the carbonate water is produced.

主权项

1. A refrigerator comprising:
a carbonated water tank in which carbonated water is storable; a water level sensor configured to sense a water level of carbonated water in the carbonated water tank; a water tank in which water is storable; a carbon dioxide cylinder in which carbon dioxide is storable; and a controller configured to: supply water from the water tank to the carbonated water tank, if the water level sensed by the water level sensor is below a predetermined minimum water level, and supply carbon dioxide from the carbon dioxide cylinder to the carbonated water tank, if the water level sensed by the water level sensor is above a predetermined maximum water level, wherein, if the carbonated water is discharged, the controller controls the water level sensor to sense the water level of the carbonated water in the carbonated water tank.
