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 first flow rate sensor provided in the water inflow passage to measure a flow rate of water flowing through the water inflow passage;
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 discharge 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 turns on the water inflow valve to dispense the hot water after the water discharge valve is turned on.
