Abstract: A gaseous fuel burner assembly for heating a space particularly an oven of a domestic cooking appliance comprises a gaseous fuel burner separated from the space by a baffle plate, and, also separated from the space by the baffle plate, a fan for withdrawing air from the space via an aperture or apertures in the plate and returning that air to the space via an exit or exits adjacent the edge of the plate, the or each aperture being so located that, during its passage from the aperture or apertures to the exit or exits, the air passes close to the burner. The fan may also draw in air from a plenum chamber behind the oven. The burner may be of the duplex variety and may have two independently controllable burner heads.

Abstract: A domestic cooker has a plenum chamber positioned to the rear of its oven cavity. Air is pump into the chamber by a fan which draws air around the outside of the cavity. Air exits from the chamber to atmosphere via a duct above the oven cavity having first passed over the cooker control panel to keep the latter at an acceptable temperature. The oven cavity has a door of a composite construction with inner and outer door panels spaced apart by a passageway open at the top and at the bottom of the door. Air from the plenum chamber flows to the passageway via a second duct located beneath the cavity. In another embodiment of the invention the cooker has two oven cavities each with a door of the composite construction, the passageways between the inner and outer panels of each door being supplied with air from a plenum chamber at the rear of the cavities.
