Abstract:
The present invention is provided with: a drum (51) having a rotational shaft having an angle with respect to the vertical direction; a drum motor (60) that holds a rotor (59) having a permanent magnet and that drives the drum (51); and an inverter circuit (71) that supplies current to the drum motor (60). The inverter circuit (71) has a first driving unit (72), a second driving unit (73), and a switching unit (74). The first driving unit (72) generates a signal independent from the magnetic pole position of the rotor (59), and the second driving unit (73) generates a signal that is in accordance with the magnetic pole position of the rotor (59). The drum motor (90) is started up by means of the signal from the first driving unit (72). The switching unit (74) switches the signal input to the drum motor (90) from the signal from the first driving unit (72) to the signal from the second driving unit (73).
