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.

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; anda 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, andsupply 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. 2. The refrigerator according to claim 1, further comprising a dispenser discharging the carbonated water, wherein, if the carbonated water is discharged through the dispenser, the controller calculates an accumulated discharge time at which all the carbonated water is discharged since the carbonated water has been produced. 3. The refrigerator according to claim 2, wherein, if the accumulated discharge time is greater than or equal to a predetermined maximum accumulated discharge time, the controller produces the carbonated water. 4. The refrigerator according to claim 2, wherein, if the carbonated water is not discharged, the controller calculates a discharge waiting time since the carbonated water has been discharged, and if the discharge waiting time is greater than or equal to a predetermined maximum discharge waiting time and the accumulated discharge time is greater than or equal to a predetermined maximum accumulated discharge time, the controller produces the carbonated water. 5. 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; anda 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, andsupply 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. 6. The refrigerator according to claim 5, further comprising a dispenser discharging the carbonated water, wherein, if the carbonated water is discharged through the dispenser, the controller calculates an accumulated discharge time at which all the carbonated water is discharged since the carbonated water has been produced, and if the accumulated discharge time is greater than or equal to a predetermined maximum accumulated discharge time, the controller produces the carbonated water. 7. 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;an input unit configured to receive a user input for producing the carbonated water from a user; anda controller configured to:supply water from the water tank to the carbonated water tank, if the user input for producing the carbonated water is input through the input unit, andsupply 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. 8. The refrigerator according to claim 7, wherein, if the carbonated water production activation instruction is input from the user, the controller determines whether carbonated water production is being performed when the carbonated water production activation instruction is input, and if it is determined that carbonated water production is being performed when the carbonated water production activation instruction is input, the controller restarts production of carbonated water being performed.
