  • Patent number: 10337742
    Abstract: A cooking appliance (1) includes a cooking chamber (4) heatable by a heating device (3), a cooking chamber opening (5), a cooking chamber door (6) closing off the cooking chamber opening (5), and a control device (7) for controlling the heating device (3). The cooking chamber door (6) has a multi-pane construction having a first pane (8) and a second pane (9). A detector device (10) operatively connected to the control device (7) is actuated by the cooking chamber door (6). In addition, a locking device (11) between the first (8) and the second pane (9) includes a locking element (12), which is held preloaded in an initial state (13) between the first (8) and the second pane (9), and if the first pane (8) is defective, the locking element (12) is automatically displaced to a locking position (14), thereby preventing a complete closure of the cooking chamber door (6).
