Einrichtung zum Schutz des Transformators eines Mikrowellenherdes gegen Überhitzung

摘要

Disclosed is a device for preventing a high voltage transformer T2 of a microwave oven from being overheated, which directly senses a temperature in a second coil L4 of the high voltage transformer T2 of the microwave oven and thereby supplies or cuts off power to the transformer T2 according to the temperature. In the device, a thermostat TH is opened/closed according to the temperature of the second coil L4 of the transformer T2 so as to regulate power supply to the first coil L3 of the transformer T2, and accordingly the transformer T2 is prevented from overheated.
