A microwave oven includes a cooking cavity defined by a rear wall,
sidewalls, an upper wall and a bottom wall, and a cooking tray installed
on the bottom wall of the cooking cavity. An upper heater is installed at
a position adjacent to the upper wall of the cooking cavity, and one or
more middle heaters are rotatably installed on the rear wall at positions
between the upper heater and the cooking tray. Upper supports are provided
between the upper heater and the one or more middle heaters so as to
horizontally protrude from each of the sidewalls, and lower supports are
provided between the one or more middle heaters and the cooking tray so as
to horizontally protrude from each of the sidewalls, so that food holding
members are removably seated on the upper and lower supports.
