Abstract

A sliding door air damper unit for a refrigerator includes a base plate having an aperture, a sliding door slidably mounted on the base plate for controlling air flow through the aperture, and a modular driving assembly for driving the sliding door. The modular driving assembly includes a housing defining an inner space, a cam device suspended from the housing and a motor mounted on the housing. The sliding door is driven by the cam device to move back and forth and can slide through a gap between the cam device and the base plate. The travel distance of the sliding door is increased and thus the aperture can be made larger to allow more air to flow through the aperture. The sliding door air damper unit allows a refrigerator compartment of the refrigerator to quickly reach a predetermined temperature setting.
