Abstract

A washing machine includes: a tub; a drum of metal material configured to be rotated in the tub; an induction heater configured to be fixed to the tub in a state of being separated from the drum, and to heat the drum; a first temperature sensor configured to have a tube of metal material heated by the induction heater and a thermistor disposed in the tube, at least a part of the tube being exposed between the tub and the drum; a second temperature sensor configured to be disposed in a position further away than the first temperature sensor from the induction heater in a circumferential direction, and detect a temperature of air between the tub and the drum; and a controller configured to control the induction heater based on a first detection value of the first temperature sensor and a second detection value of the second temperature sensor.
