A turntable () for an oven comprising a surface for heating a food item () placed on the turntable (), wherein the turntable () is provided with integral heating means (). The turntable may be incorporated into an oven cavity () of an oven.

Turntable incorporating heating means and oven incorporating the same

A microwave oven (,) comprises an oven cavity (,) containing a rotatable turntable (,) for supporting one or more items to be heated. A radiant electric heater (,) is arranged for location above the turntable (,) and comprises at least one first heating element (,) and at least one second heating element (,). The at least one first heating element (,) overlies only a proportion of the total upper surface area of the turntable (,) such that, in operation, for each complete rotation of the turntable substantially all parts of the upper surface of the turntable are heated for substantially the same duration of time, the at least one first heating element (,) providing a first power density. The at least one second heating element (,), or a combination with the at least first heating element (,), overlies substantially the total upper surface area of the turntable (,), with the at least one second heating element operated alone, or an operating combination of the at least one second heating element (,) with the at least one first heating element (,), providing a second power density lower than the first power density.

Radiant electric heater for a microwave oven

An electric oven (,) has an oven cavity (,) for receiving one or more items to be heated, and a radiant electric heater (,) incorporating at least one heating element (,). The heater (,) is supported at a wall (,) of the cavity and has a face (,) directed towards the cavity (,) for radiating heat into the cavity from the at least one heating element (,). The face (,) of the heater is covered by a light-permeable sheet (,) spaced from the heating element (,), the sheet being in the form of a fabric which may comprise filaments or a lattice of glass, ceramic, or metal. An electric lamp (,) is provided behind the sheet (,) and additional to the at least one heating element (,) and is arranged to provide illumination of the oven cavity (,) through the sheet.
