Microwave oven

摘要

A microwave oven has a high-voltage transformer (HVT) and inrush current limiting means (100). The inrush current limiting means (100) comprises a current limiting resistor (PTC), such as a positive temperatire coefficient thermistor, actuating means (120), first and second contact members (113, 114) connected bythe resistor (PTC), and a third contact member (115) driven by the actuating means (120) to sequentially contact the first contact member (113) and then the second contact member (114). The actuating means (120) may be a solenoid or a motor-driven cam (124).
