Abstract:
1. A microwave oven, comprising: a magnetron; a transformer assembly accommodating a transformer and filled with a cooling material to cool the transformer and having a base, the transformer to supply power to the magnetron; an electrical components area attached to the base; the base formed by bending each end thereof downwardly and inwardly to space the transformer from the surface of the electrical components area by a certain distance; a temperature-sensitive switch electrically connected to the transformer to shut off external power supplied to the transformer when a temperature of a surface of the transformer assembly is a predetermined overheating temperature, wherein the temperature-sensitive switch is directly mounted on an outside surface of the transformer assembly; an input line connected to the transformer through a top of the transformer assembly to provide the external power to the transformer; and an output line connected to the transformer through the top of the transformer assembly to provide the power to the magnetron, the input line and the output line being connected to the top of the transformer assembly using epoxy resin to keep the transformer assembly tightly sealed.
