Abstract
A control device, for a water purifier, that dispenses hot water and that includes: an input unit that is configured to receive a command signal; and a controller that is configured to control the water purifier based on the command signal, wherein the controller is configured to: control power output of a heating unit that is configured to heat water stored in a hot water tank of the water purifier, and based on the power output of the heating unit, control temperature of hot water dispensed by the water purifier is disclosed.
Claims7
A control device of a water purifier that dispenses hot water, the control device comprising:
- an input unit that receives, from a user, a command signal including information regarding a set temperature;
- and
- a controller that is configured to control the water purifier based on the command signal,
- wherein the controller is configured to:
- control power output of an induction heater that is configured to, based on the set temperature, heat water stored in a hot water tank of the water purifier to thereby generate hot water to be dispensed,
- control a temperature of the hot water dispensed by the water purifier based on the power output of the induction heater,
- control the power output of the induction heater by controlling a frequency or a phase of AC power supplied to the induction heater,
- control the frequency or the phase of AC power applied to the induction heater based on a difference between a detected temperature of water introduced into the hot water tank and a detected temperature of the hot water dispensed from the hot water tank compared to a preset difference reference, and
- adjust an angle of a flow rate valve that is positioned at an upstream of the hot water tank and that is configured to control a flow channel configured to supply purified water from a filter to the hot water tank.

A water purifier comprising:
- an input unit that receives, from a user, a command signal including information regarding a set temperature;
- an inlet part through which purified water is introduced;
- a hot water tank that is configured to store water introduced through the inlet part;
- a flow rate valve positioned at an upstream of the hot water tank and configured to adjust a flow rate of water introduced to the hot water tank, the flow rate valve being configured to control a flow channel that is configured to supply purified water from a filter to the hot water tank;
- an induction heater that is configured to, based on the set temperature, heat water stored in the hot water tank to thereby generate hot water to be dispensed;
- a water dispense part that is configured to dispense the hot water stored in the hot water tank;
- and
- a control device that is configured to:
- control power output of the induction heater based on the set temperature,
- control a temperature of the hot water dispensed by the water dispense part based on the power output of the induction heater,
- control the power output of the induction heater by controlling a frequency or a phase of AC power supplied to the induction heater,
- control the frequency or the phase of AC power applied to the induction heater based on a difference between a detected temperature of water introduced into the hot water tank and a detected temperature of the hot water dispensed from the hot water tank compared to a preset difference reference, and
- adjust an angle of the flow rate valve.
10 more elements
A control method of a water purifier, the control method comprising:
- receiving a command signal including information regarding a set temperature;
- receiving purified water;
- storing the purified water in a hot water tank of the water purifier,
- wherein the water purifier includes a heating unit that is configured to heat water stored in the hot water tank based on the set temperature and that includes an induction heater;
- controlling power output of the heating unit by controlling a frequency or a phase of AC power supplied to the heating unit;
- based on the power output of the heating unit, controlling a temperature of hot water dispensed from the hot water tank;
- dispensing the hot water from the hot water tank;
- controlling the frequency or the phase of AC power applied to the induction heater based on a difference between a detected temperature of water introduced into the hot water tank and a detected temperature of the hot water dispensed from the hot water tank compared to a preset difference reference;
- and
- adjusting an angle of a flow rate valve positioned at an upstream of the hot water tank.
