IPC: F24C7/02
Filed: 2001-03-21
Abstract: PROBLEM TO BE SOLVED: To perform oven and grill cooking effectively with an optimum heater mounting for an electronic microwave oven having heater function. SOLUTION: The microwave oven comprises a heating section and a heater having an electric heating wire inserted in an insulating protection tube 35 located on the top of the heating section.
