PROBLEM TO BE SOLVED: To construct a dish washing and drying machine with an inverter device having a small number of switching elements by connecting a series circuit of a third diode and a coil between a connection point of a first switching element and a first diode and a connecting point of a second switching element and a second diode. SOLUTION: A second motor 21 generates power by the operation called switched reluctance motor. During the drainage period, a first switching element 61 is turned on, so that an electric current is sequentially supplied to coils 80-82 of a third motor 22 to generate power. During the drying period, a first switching element 59 is turned on, so that an electric current is sequentially supplied to coils 94-96 of a first motor 20 to generate power. Thus, three first switching elements and three second switching elements are provided to drive three motors in a comparatively simple constitution. |
