Raised-level built-in cooking appliance

Abstract

A raised-level built-in cooking appliance, such as a wall-mounted oven, has a muffle and a bottom-side muffle opening. The latter can be closed with a lowerable bottom door. A drive device produces a lifting movement of the bottom door. In order to determine the weight of a cooking item, the wall-mounted cooking appliance has a weight detection device that determines the weight load on the bottom door.

I claim:  
     
         1 . A wall-mounted cooking appliance, comprising: 
 a housing formed with a muffle and a bottom muffle opening;    a lowerable bottom door for selectively closing said muffle opening;    a drive mechanism for lifting said bottom door; and    a weight detection device configured to determine a dead-weight loading of said bottom door.    
     
     
         2 . The cooking appliance according to  claim 1 , wherein, when a maximum value of the dead-weight loading is exceeded, said weight detection device is configured to interrupt said drive mechanism.  
     
     
         3 . The cooking appliance according to  claim 1 , wherein said weight detection device includes at least one tensile force sensor for detecting a tensile force exerted by said drive mechanism on said bottom door, for determining the dead-weight loading.  
     
     
         4 . The cooking appliance according to  claim 3 , wherein said weight detection device is configured to interrupt said drive mechanism when the tensile force drops below a lower threshold value of the tensile force.  
     
     
         5 . The cooking appliance according to  claim 3 , wherein said weight detection device is configured to interrupt said drive mechanism when the tensile force exceeds an upper threshold value of the tensile force.  
     
     
         6 . The cooking appliance according to  claim 1 , wherein said drive mechanism has at least one tensile element connected to said bottom door and a driven shaft for winding and unwinding said tensile element, and wherein said weight detection device has a torque sensor for detecting a torque on said driven shaft and for determining the dead-weight loading.  
     
     
         7 . The cooking appliance according to  claim 1 , wherein said drive mechanism is an electromotor, and said weight detection device is configured to detect a recorded electric current of said electromotor to determine the dead-weight loading.  
     
     
         8 . The cooking appliance according to  claim 1 , which comprises a control device for controlling respective cooking and roasting cycles of the cooking appliance in dependence on the detected dead-weight loading.
