Abstract
A laundry machine includes a tub, a drum that is rotatably mounted in the tub, and an induction heater that is provided in the tub and configured to heat an outer circumferential surface of the drum. The laundry machine also includes a motor that is configured to rotate the drum, a temperature sensor that is configured to sense the temperature inside the tub, an instantaneous power output unit configured to calculate and output an instantaneous output, and a processor that controls drum rotation speed and heat-spinning by controlling the induction heater. The processor may control the output of the induction hater to be variable based on the output of the instantaneous power output unit.
Claims20
A laundry machine comprising:
- a tub;
- a drum that is rotatably mounted in the tub and that is configured to hold laundry;
- an induction heater that is located in the tub and configured to heat an outer circumferential surface of the drum;
- a motor that is located at a rear side of the tub and that is configured to rotatably drive the drum;
- a power output unit configured to calculate and output power to the laundry machine;
- a processor that is configured to control driving of the drum, and that is configured to control a heat-spinning operation by controlling driving of the induction heater;
- and
- a temperature sensor that is connected to the processor and that is configured to sense a temperature inside the tub,
- wherein the processor is configured to, based on the power output by the power output unit, variably control the induction heater, and
- wherein the heat-spinning operation comprises heating the laundry by driving the induction heater during rotation of the drum.
A control method of operating a laundry machine comprising:
- a tub;
- a drum that is rotatably mounted in the tub and configured to hold laundry;
- an induction heater that is located in the tub and configured to heat an outer circumferential surface of the drum;
- a motor that is located at a rear side of the tub and that is configured to rotatably drive the drum;
- a power output unit configured to calculate and output power to the laundry machine;
- and a processor that is configured to control driving of the drum, and that is configured to control a heat-spinning operation by controlling driving of the induction heater;
- and a temperature sensor that is connected to the processor and that is configured to sense a temperature inside the tub, the control method comprising:
- calculating power output by the power output unit;
- based on the calculated power, setting an output of the induction heater to be variable;
- and
- performing a heat-spinning operation by driving the induction heater based on a preset output of the induction heater.
