Manual air damper control for a refrigerator

摘要

A manual air damper control for a refrigerator is provided to convert rotary motion of a control knob disposed on a front panel in the refrigerator compartment into linear motion of an air damper disposed at the rear of the refrigerator compartment to operate the air damper in a limited space. The control includes a cam having a cam shaft on which the control knob is mounted and having a cam surface engaged by a cam following fork formed in one end of a pivot arm. The opposite end of the pivot arm engages a connecting rod which extends from the front of the refrigerator compartment to the rear thereof where the connecting rod engages the air damper to slide the air damper toward and away from the front of the refrigerator compartment. The air damper is a slide baffle which cooperates with an air passageway disposed between the refrigerator and freezer compartments so as to form a trapezoidally shaped opening into the refrigerator compartment to provided a controlled linear flow of air as the air damper is displaced.
