Abstract

A method for operating a cooking appliance including at least one treatment chamber with at least one opening for filling the treatment chamber, at least one door for closing the opening of the treatment chamber, at least one control device, and at least one safety device, includes: checking the at least one treatment chamber, by the at least one safety device, for a presence of at least one living being and/or at least one object which could potentially disrupt operation; and if the at least one safety device detects that at least one living being and/or at least one object which could potentially disrupt operation are/is present in the at least one treatment chamber, preventing, by the control device, operation of the cooking appliance and/or limits operation of the cooking appliance to certain operating states.

1 .

         6 . The method of  claim 1 ,
 wherein the at least one safety device comprises at least one sensor configured to detect a change in an electrical conductivity in the treatment chamber.   
     
     
         7 . The method of  claim 1 ,
 wherein the at least one safety device comprises at least one sensor configured to detect devices for wireless communication and/or signals emitted by devices for wireless communication in at least one the treatment chamber.   
     
     
         8 . The method of  claim 1 ,
 wherein the at least one safety device is configured to detect a size and/or a position of at least one object in the at least one treatment chamber and draw conclusions therefrom about a presence of at least one second object that could disrupt operation, and/or at least one living being.   
     
     
         9 . The method of  claim 1 ,
 wherein the at least one safety device comprises at least one ultrasonic sensor.   
     
     
         10 . The method of  claim 1 ,
 wherein the at least one safety device comprises at least one weight sensor.   
     
     
         11 . The method of  claim 1 ,
 wherein the at least one safety device comprises at least one gas sensor configured to detect a change in a concentration of at least one gas in the at least one treatment chamber.   
     
     
         12 . The method of  claim 1 ,
 wherein the at least one safety device is configured to detect at least one deformation and/or at least one distortion of at least one wall enclosing the at least one treatment chamber.   
     
     
         13 . The method of  claim 1 ,
 wherein the at least one safety device comprises at least one photosensitive sensor configured to detect at least one change in light intensity in the at least one treatment chamber.   
     
     
         14 . The method of  claim 1 ,
 wherein the at least one safety device is configured to detect at least one change in a flow pattern and/or in a flow intensity of air in the at least one treatment chamber.   
     
     
         15 . The method of  claim 1 ,
 wherein the at least one safety device comprises at least one acoustic sensor configured to detect at least one acoustic sound.   
     
     
         16 . The method of  claim 1 ,
 wherein the at least one safety device is configured to detect at least one movement of the at least one door and/or at least one application of force on at least one portion of the at least one door.   
     
     
         17 . The method of  claim 1 ,
 wherein the at least one safety device comprises a plurality of safety devices and/or is configured to use signals of a plurality of safety devices for detecting at least one living being and/or at least one object which could potentially disrupt operation.   
     
     
         18 . The method of  claim 1 ,
 further comprising:
 requesting at least one enable input from at least one user to enable user control of the cooking device based on detection, by the at least one safety device, of at least one living being and/or at least one object in the at least one treatment chamber which could potentially disrupt operation.
