Abstract
Damper mechanisms are provided in conjunction with housings of various different appliances and are disposed at first positions at which the dampers effectively close off or seal the interior regions of the appliances within which various heated, refrigerated, or frozen environments have been established. Such damper mechanisms can be moved to second positions so as to permit food items to be inserted into, or extracted from, the various housings of the appliances, but will automatically return to their first positions so as to again close off or seal the interior regions of the appliances. In this manner, thermal energy is preserved whereby the appliances are enabled to operate at peak energy efficiency.
