  • Patent number: 6091057
    Abstract: A broiler oven has a heating chamber 2, first and second movable heaters 61 and 62 formed out of tubular heaters and rotatably supported by the inner walls of the heating chamber 2 in such a way that their heating portions 61b and 62b and their shaft portions 61a and 62a joined together so as to be parallel to each other by their arm portions 61c and 62c are held at an equal level, a driving mechanism 12 for rotating the shaft portions 61a and 62a, and a control circuit 10 for controlling the first and second movable heaters 61 and 62 and the driving mechanism 12. The control circuit 10 controls the driving mechanism 12 to rotate the first and second movable heaters 61 and 62 between a non-heating position and a heating position, and energizes the first and second movable heaters 61 and 62 when they are in the heating positions.
