摘要
A microwave oven of the hot air circulation type comprises a perforated panel (3) separating the cooking chamber (1) from an adjacent fan compartment (5), the panel perforations permitting air circulation but preventing escape of microwave energy from the cooking chamber (1). The panel (3) has a peripheral wall (9) provided with transverse slits (10) to prevent microwave propagation in peripheral directions along the panel wall (9) and a set of spacer elements (13), each of which is arranged to bring a screw (18) into alignment with a bore (16) in the panel (3) for securing the panel (3) to an oven wall member (4) outwardly defining the fan compartment (5). This panel (3) can readily be mounted during oven assembly and, when mounted, it satisfies the requirements on air circulation and microwave energy sealing, but it can also readily be removed when access to the fan compartment (5) is called for.
