ABSTRACT:
The baffle for controlling flow of chilled air through the divider wall between the frozen food and fresh food compartments of a refrigerator is coupled to a motor driven cam which indexes the baffle open or closed in response to commands from a conventional control unit. Electrical switches for controlling the compressor and defrost heater of the refrigerator are positioned axially along the cam to be operated selectively by concentric cam surfaces as the cam is rotated by the motor. A cam follower engages another concentric cam surface to operate another set of switches to apply rotational positional feedback signals to the control unit. The cam surfaces are shaped and the baffle is coupled to the cam such that unidirectional rotation of the cam in response to commands from the control unit operates the switches synchronously with the baffle to selectively cool the frozen food and fresh food compartments and defrost the evaporator.
