Abstract
A sheath heater is disposed below a turntable in a combination microwave and electric oven to maintain an oven temperature at a predetermined value. The sheath heater is shaped in such a manner that a loop size surrounded by the sheath heater is greater than the turntable size. That is, the sheath heater substantially protrudes beyond the periphery of the turntable to enhance the heating efficiency of the oven.
