Abstract
A washing machine includes: a tub; a drum; an induction heater disposed in a position spaced apart from the drum and configured to heat the drum; an input power source; a relay configured to interrupt a current applied to the coil of the induction heater from the input power source; a first processor configured to control the relay; and a safety device connected to a circuit connecting the first processor and the relay. The safety device includes: a first thermostat configured to operate according to a temperature of a first air between the drum and the tub, and open the circuit when the temperature of the first air is a first safety control temperature; and a thermal fuse configured to operate according to a temperature of a second air outside the tub, and open the circuit when the temperature of the second air is a second safety control temperature.
