MOTORIZED DOOR ASSEMBLY WITH SAFETY FEATURES FOR HEATED CABINET
Motorized door assemblies having a door pivoting about a pivot axis extending across opposing jambs. In one aspect, the assembly includes a motor assembly having a motor, drive gears, slip clutch, and driven shaft connected to the door to pivot it about the pivot axis. The slip clutch includes a clutch plate slideable along the driven shaft, a drive plate driven by the motor via the drive gears, and a clutch spring urging the clutch plate into engagement with the drive plate, where the clutch and drive plates have profiled and counter-profiled faces. In another aspect, a break beam emitter and receiver are mounted to respective ones of the opposing jambs along a beam axis extending parallel to the pivot axis and proximate to an edge of the door opposite the pivot axis. Interruption of a light beam projected therebetween alters operation of a motor assembly.
