Abstract:
A washing machine includes: a tub; a drum; a temperature sensor configured to detect a temperature of air between the drum and the tub; an induction heater configured to heat the drum; a controller unit configured to control the induction heater within a preset control temperature range; a circuit configured to supply power to the induction heater; a first thermostat configured to operate according to a first temperature of air between the drum and the tub and open the circuit when the first temperature is a first safety control temperature; and a thermal fuse configured to operate according to a second temperature of air outside the tub and open the circuit when the second temperature is a second safety temperature corresponding to a case where the temperature of the drum is in a second safety temperature range having a larger value than the first safety temperature range.
