Abstract
A microwave oven cavity 2 is provided by a magnetron(s) with microwave energy for providing heat in the thermal cavity. Hot air is supplied by a heated air supply and director (21,22,24). Cool air, at least a portion of which is able to assist in containing and/or directing at least a portion of said hot air, is also supplied via a sleeve (31) so as to provide localization of at least a portion of said hot air in the thermal cavity, and optionally to prevent or reduce heat reaching at least a portion of the boundary of the thermal cavity.
