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 ).

First claim

What is claimed is:

1. A cooking appliance ( 1 ) comprising
a heating device ( 3 ),
a cooking chamber ( 4 ) having a cooking chamber opening ( 5 ) and heatable by the heating device ( 3 ),
a control device ( 7 ) for controlling the heating device ( 3 ), and
a cooking chamber door ( 6 ) closing off the cooking chamber opening ( 5 ), the cooking chamber door ( 6 ) having a multi-pane construction with a first pane ( 8 ) and a second pane ( 9 ),
a detector device ( 10 ) in operative connection to the control device ( 7 ), the detector device disposed in the cooking chamber ( 4 ) or on the cooking chamber door ( 6 ), the detector device ( 10 ) being actuated by the cooking chamber door ( 6 ) when the cooking chamber door ( 6 ) is completely closed, and unblocks the control device, and
a locking device ( 11 ) between the first ( 8 ) and the second ( 9 ) pane, the locking device ( 11 ) including a locking element ( 12 ) held preloaded in an initial position ( 13 ) completely between the first ( 8 ) and the second pane ( 9 ), wherein the locking element ( 12 ) is configured to be automatically displaced to a locking position ( 14 ) in the event of a defective first pane ( 8 ) and to prevent a complete closure of the cooking chamber door ( 6 ).

2. The cooking appliance ( 1 ) according to claim 1 , wherein in the case of a defective first pane ( 8 ), the locking element ( 12 ) hits against a section ( 15 ) of a housing device ( 2 ) when the cooking chamber door ( 6 ) is closed.

3. The cooking appliance ( 1 ) according to claim 1 , wherein the locking device ( 11 ) comprises a preloading device ( 16 ).

4. The cooking appliance ( 1 ) according to claim 1 , wherein the locking device ( 11 ) comprises a holding device ( 17 ), on which the locking element ( 12 ) is movably received.

5. The cooking appliance ( 1 ) according to claim 1 , wherein the locking device ( 12 ) comprises a securing device ( 20 ).

6. The cooking appliance ( 1 ) according to claim 1 , wherein the locking device ( 11 ) is received on the second pane ( 9 ).

7. The cooking appliance ( 1 ) according to claim 1 , wherein the cooking chamber door ( 6 ) comprises a spar device ( 21 ), and in that the locking device ( 11 ) is received on the spar device ( 21 ).

8. The cooking appliance ( 1 ) according to claim 1 , wherein the detector device ( 10 ) comprises a pressure switch ( 22 ).

9. The cooking appliance ( 1 ) according to claim 1 , wherein the detector device ( 10 ) comprises a first detector element ( 23 ) and a second detector element ( 24 ) cooperating with the first detector element ( 23 ), wherein the first detector element ( 23 ) is attached to the cooking chamber door ( 6 ), and wherein the second detector element ( 24 ) is attached to the cooking chamber ( 4 ).

10. The cooking appliance ( 1 ) according to claim 1 , wherein the cooking chamber door ( 6 ) comprises a third pane ( 25 ).

11. A cooking appliance ( 1 ) comprising
a heating device ( 3 ),
a cooking chamber ( 4 ) having a cooking chamber opening ( 5 ) and heatable by the heating device ( 3 ),
a control device ( 7 ) for controlling the heating device ( 3 ), and
a cooking chamber door ( 6 ) closing off the cooking chamber opening ( 5 ), the cooking chamber door ( 6 ) having a multi-pane construction with a first pane ( 8 ) and a second pane ( 9 ),
a detector device ( 10 ) in operative connection to the control device ( 7 ), the detector device disposed in the cooking chamber ( 4 ) or on the cooking chamber door ( 6 ), the detector device ( 10 ) being actuated by the cooking chamber door ( 6 ) when the cooking chamber door ( 6 ) is completely closed, and unblocks the control device, and
a locking device ( 11 ) between the first ( 8 ) and the second ( 9 ) pane, the locking device ( 11 ) including a locking element ( 12 ) held preloaded in an initial position ( 13 ) between the first ( 8 ) and the second pane ( 9 ), wherein the locking element ( 12 ) is configured to be automatically displaced to a locking position ( 14 ) in the event of a defective first pane ( 8 ) and to prevent a complete closure of the cooking chamber door ( 6 ),
wherein the locking element ( 12 ) is held in the initial position ( 13 ) generally parallel to at least one of the first ( 8 ) and the second ( 9 ) panes, and in that, in the event of the defective first pane ( 8 ), the locking element ( 12 ) is at an angle ( 18 ) to the at least one of the first ( 8 ) and the second ( 9 ) panes.

12. The cooking appliance ( 1 ) according to claim 11 , wherein the locking element ( 12 ) is pivotably received on the holding device ( 17 ).

13. The cooking appliance ( 1 ) according to claim 11 , wherein the locking element ( 12 ) is displaceably received on the holding device ( 17 ).

14. The cooking appliance ( 1 ) according to claim 13 , wherein in the initial position ( 13 ) the locking element ( 12 ) has a longitudinal axis positioned at an angle ( 18 ) to the first ( 8 ) or the second pane ( 9 ), and in that, in the event of the defective first pane ( 8 ), the locking element ( 12 ) expands in the axial direction ( 19 ) into the locking position ( 14 ).
