ABSTRACT:
A refrigerator having a middle fresh food compartment and a relatively large bottom freezer compartment arranged below the fresh food compartment and a relatively small freezer compartment arranged above the fresh food compartment. The bottom freezer compartment preferably supports a drawer including a frame and a removable bin. Cool air can be supplied to the compartments of the refrigerator by employing a two fan control system such that no electromechanical baffles are required. Alternatively, cool air can be directed to the compartments of the refrigerator by use of a baffle which requires only a single electromechanical device to control air flow into three different compartments. The baffle includes a main rotary damper which can be positioned to provide proportional amounts of chilled air to the three separate compartments based on the degree of cooling required.
