Abstract

A microwave oven comprising an oven-defining structure having an access opening leading into a heating chamber defined therein, a drawer type door assembly of substantially L- shaped configuration including a door structure 13, adapted to selectively close and open the access opening, a rail structure 19 movably supported to facilitate the movement of the door structure between closed and opened positions, a microwave power source 2 for supplying microwave energy to the heating chamber, and hook members each having a plurality of hooks 24 for the support of a rack adapted to support thereon a material to be heated, the door assembly being provided with a capacitive coupling and a choke cavity which form a microwave seal when the door assembly is closed. The microwave oven may further include a tray through which the material to be heated is mounted on the rack. The door structure is designed so as to maintain a parallel relation to the plane of the access opening during movement between the closed and open positions. <IMAGE>
