Abstract

A refrigerator may include 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; a dispenser discharging the carbonated water or the filtered water; and a controller, if the filtered water is supplied to the carbonated water tank and supply of the filtered water is completed, supplying the carbon dioxide to the carbonated water tank so as to produce the carbonated water, wherein the controller stops producing the carbonated water if a discharge instruction of the filtered water is input from a user or if a door of the refrigerator is opened while the carbonated water is produced. Filtered water and carbonated water can be selectively taken, and when a user wants to use filtered water or opens a door of a refrigerator while carbonated water is produced, the refrigerator that stops production of carbonated water is provided so that the user can be prevented from misunderstanding that the refrigerator is broken.

First claim

What is claimed is:

1. A method of controlling a refrigerator comprising a carbonated water tank in which carbonated water is produced and stored, the method comprising:
supplying filtered water to the carbonated water tank; and
if the supplying of the filtered water is completed, supplying carbon dioxide to the carbonated water tank,
wherein, if a discharge instruction of the filtered water is input from a user while the filtered water is supplied to the carbonated water tank, stopping the supply of filtered water to the carbonated water tank and discharging the filtered water, and
if the discharging of the filtered water is completed while the supply of the filtered water to the carbonated water tank is stopped, restarting the supply of the filtered water to the carbonated water tank.

2. The method according to claim 1 , further comprising, if the discharge instruction of the filtered water is input from the user while the filtered water is supplied to the carbonated water tank, storing a production progress of the carbonated water.

3. The method according to claim 1 , further comprising, if a discharge termination instruction of the filtered water is input from the user while the supply of the filtered water is stopped, restarting the supply of the filtered water.

4. A method of controlling a refrigerator comprising a carbonated water tank in which carbonated water is produced and stored, the method comprising:
supplying filtered water to the carbonated water tank; and
if the supplying of the filtered water is completed, supplying carbon dioxide to the carbonated water tank,
wherein, if a door of the refrigerator is opened by a user while the filtered water is supplied to the carbonated water tank or the carbon dioxide is supplied to the carbonated water tank, stopping the supply of the filtered water or stopping the supply of the carbon dioxide.

5. The method according to claim 4 , further comprising, if the door of the refrigerator is opened by the user while the filtered water is supplied to the carbonated water tank or the carbon dioxide is supplied to the carbonated water tank, storing a production progress of the carbonated water.

6. The method according to claim 4 , further comprising, if a discharge termination instruction of the filtered water is input from the user while supply of the filtered water is stopped or supply of the carbon dioxide is stopped, restarting the supply of the filtered water or the supply of the carbon dioxide.
