Abstract
A water dispenser and a method of controlling a water dispenser are provided. The water dispenser may control power output of an induction heater having a hot water module based on changes in flow rate of water supplied or a temperature of water discharged.
Claims20
A water dispenser, comprising:
- a tube configured to receive water;
- a flow sensor provided along the tube, the flow sensor configured to sense an amount of water flowing through the tube;
- a water tank configured to receive the water;
- a heater to heat the water in the water tank by induction heating;
- and
- a controller that reduces power output of the heater when a flow rate of water sensed by the flow sensor is a prescribed flow rate or less.
3 more elements
A water dispenser comprising:
- a water storage tank to receive water;
- an induction heater that heats water in the water storage tank;
- a discharge pipe that discharges water heated by the induction heater from the water storage tank;
- a temperature sensor provided on the discharge pipe, the temperature sensor configured to sense a temperature of water discharged from the discharge pipe;
- and
- a controller that reduces power output of the induction heater when the temperature of water sensed by the temperature sensor is a prescribed temperature or higher.
3 more elements
A method of controlling a water dispenser having a discharge valve that is opened by a user to dispense water, an induction heater that heats and discharges water, a flow sensor that measures flow rate of water, and a controller that controls a power output of the induction heater, the method comprising:
- measuring a change in the flow rate of water supplied using the flow rate sensor;
- dispensing water through the discharge valve;
- and
- maintaining a temperature of water dispensed at a predetermined level based on a change in the flow rate of the water supplied.
