An electric oven includes a housing having a door at a front, a chamber in
an interior and a motor at a bottom; rotating devices installed in the
housing and each consisting of an upper frame, a lower frame, roller seat
assemblies, a gear wheel, a driven shaft and a driven gear; and, net racks
capable of being rested on the gear wheels. In using, the motor is
actuated to turn the driven shafts and gears to synchronously rotate the
gear wheels to make the net racks rotated accordingly for roasting food
articles evenly. The rotating devices designed to be located in multiple
layers can be placed with various food articles, thus enabling one single
electric oven to roast the various food articles at the same time. A pan
can be rested on the rotating device that is positioned at a top layer for
frying, roasting, boiling and deep-frying.
