Abstract

A microwave oven, particularly for reheating items on a tray for serving meals in hospitals, where items on a portion of the tray are protected from being heated, as in the main patent, has an inside shelf, over which the tray (320) is pushed, with food (326) at its front, to be heated, and further items at its rear to remain unheated. The rear edge of the tray pushes against a curved strip (206) attached to the underside of a cover (200) which swings down to protect the rear items. Strips (106) on the top of the cover pass through holes at the rear and engage a spindle (416) at the rear, connected with the power switch, via a spring loaded arm (412) which is also connected with further arms actuated when the access door is closed. Thus power cannot be switched on unless the appropriate items to be protected are properly screened.
