Refrigerator and method for controlling a refrigerator
First Claim
1. A refrigerator, comprising:
- a cabinet to define a storage space;
a door to open and close the storage space;
a dispenser provided in the door to dispense hot water;
a hot water tank through which water flows to heat water introduced into the door;
a heater provided in the door to heat the hot water tank;
a water inflow passage through which water is supplied to the hot water tank;
a water discharge passage to guide hot water discharged from the hot water tank to the dispenser;
a water inflow valve provided in the water inflow passage to adjust a flow of water in the water inflow passage;
a water discharge valve provided in the water outlet passage;
an input provided to input a temperature of the hot water to be dispensed and a hot water dispensing command; and
a controller to control the water inflow valve and the water discharge valve, wherein the controller turns off the water inflow valve and the water discharge valve in a hot water dispensing standby state and turns on the water inflow valve and the water discharge valve in a hot water dispensing process, and wherein, when the hot water dispensing is finished, the controller turns off the water discharge valve after turning off the water inflow valve.

14. A method for controlling a refrigerator, the method comprising:
-
inputting a hot water dispensing command; turning on a water inflow valve disposed at an inlet-side of a hot water tank and a water discharge valve disposed at an outlet-side of the hot water tank, by a controller; determining, by the controller, whether dispensing of hot water is completed; and turning off the water discharge valve after the water inflow valve is turned off when the dispensing of the hot water is completed, by the controller. - View Dependent Claims (15, 16, 17)

18. A refrigerator, comprising:
-
a cabinet to define a storage space; a door to open and close the storage space; a dispenser provided in the door to dispense hot water; a hot water tank through which water flows to heat water introduced into the door; a heater provided in the door to heat the hot water tank; a water inflow passage through which water is supplied to the hot water tank; a water discharge passage to guide hot water discharged from the hot water tank to the dispenser; a water inflow valve provided in the water inflow passage to adjust a flow of water in the water inflow passage; a water discharge valve provided in the water outlet passage; an input provided to input a temperature of the hot water to be dispensed and a hot water dispensing command; and a controller to control the water inflow valve and the water discharge valve, wherein the controller turns off the water inflow valve and the water discharge valve in a hot water dispensing standby state and turns on the water inflow valve and the water discharge valve in a hot water dispensing process, and wherein the controller determines whether preheating is necessary when a hot water dispensing command is input through the input and operates the heater to preheat the water within the hot water tank in a state in which the water inflow valve and the water discharge valve are closed when it is determined that the preheating is necessary.
