Abstract

Abstract A microwave cooker having two adjacent cookers (3,5). A source of microwave energy is mounted in a wave guide (15) having two branches (19,21) each connecting with an oven so as to direct microwave energy thereto. A deflector means (29) is provided to selectively block one or other of the branches so as to direct radiation to the other oven. One of the ovens also has a heating element thereby enabling the oven to be heated by the element and/or microwave energy directed thereto

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 101 words
A microwave cooker comprising two adjacent ovens (3, 5), a mode stirrer (11, 13) disposed in each oven, a source of microwave energy (27) and a wave guide (15), accomodating said source and having respective branches (19, 21) which connect with the ovens so as to guide microwave energy towards the corresponding mode stirrer, characterised in that the wave guide includes deflector means (29) for directing microwave energy exclusively along one or other of the branches and that one of the ovens includes a heating element enabling said one oven to be heated by said element and/or microwave energy directed thereto.
Claim 2
Dependent Claim 101 words
A microwave cooker comprising two adjacent ovens (3, 5), a mode stirrer (11, 13) disposed in each oven, a source of microwave energy (27) and a wave guide (15), accomodating said source and having respective branches (19, 21) which connect with the ovens so as to guide microwave energy towards the corresponding mode stirrer, characterised in that the wave guide includes deflector means (29) for directing microwave energy exclusively along one or other of the branches and that one of the ovens includes a heating element enabling said one oven to be heated by said element and/or microwave energy directed thereto.
Claim 3
Dependent Claim 51 words
2 . A microwave cooker according to Claim 1 characterised, in that said deflector means comprises a flap, disposed within the wave guide and a drive means for moving the flap into a respective position appropriate for blocking one or other of the branches to prevent passage of microwave energy therethrough.
Claim 4
Dependent Claim 42 words
3 . A microwave cooker according to Claim 2 charactised in that the source of microwave energy is situated in a common portion of the wave guide, the flap being pivotally mounted at the junction between the common portion and the branches.
Claim 5
Dependent Claim 37 words
A microwave cooker according to Claims 2 or 3 characterised in that the flap in each said respective position thereof, is inclined to the axis of the common portion to thereby direct energy along the respective branch.
Claim 6
Dependent Claim 91 words
A microwave cooker according to Claim 1 characterised in that the source is mounted within a common portion of 'the wave guide . and that the deflector means comprises a block which is mounted for rotation about a fixed axis at the junction between the common portion-and the branches and has a drive means for effecting its rotation, the block having a passageway which is shaped to'connect the common portion exclusively to one or other of the branches in dependence on its position to thereby direct energy to the corresponding oven.
Claim 7
Dependent Claim 75 words
A microwave cooker according to Claim 5 characterised in that the block is cylindrical and is mounted within the bore of the housing to which the said branches and the common portion of the wave guide are connected, the housing having ducts which communicate between the bore and a respective branch or common portion, so as to permit energy to be directed to one or other of the ovens via the passageway in the block.
Claim 8
Dependent Claim 36 words
A microwave cooker according to Claim 1 wherein each branch has a slidable shutter member which may be selectively located so as to block the associated branch and thereby direct energy exclusively along the other branch.
