To provide a washing machine which prevents an abnormal increase in a temperature of a wall surface of a main duct.
First rear heater driving processing, both-heater driving processing, and second rear heater driving processing are carried out sequentially when a heating course is set. An air conditioning fan motor is driven at the maximum speed during each of the first rear heater driving processing and the both-heater driving processing. Since warm air is sucked inside the main duct 32 from a heater housing chamber 58 while forming a large arc, the warm air hardly makes contact with the wall surface of the main duct 32 in front of the heater housing chamber 58. The air conditioning fan motor 65 is driven at a speed lower than the maximum speed during the second rear heater driving processing. Since the warm air is sucked inside the main duct 32 from the heater housing chamber 58 while forming a small arc, the warm air makes contact with the wall surface of the main duct 32 in front of the heater housing chamber 58. However, since the driving of a front heater 61 close to a part where the warm air makes contact in the main duct 32 is halted, it is possible to prevent an abnormal increase in the temperature due to heating of the main duct 32 by both warm air and the front heater 61.
