REFRIGERATOR MULTIPLEX DAMPER SYSTEM

摘要

A refrigerator (100) includes at least a first compartment (130) cooled to a first temperature and a second compartment (140) cooled to a second temperature, and a multiplex damper system (150) disposed in a cooling-air passage (120) so as to selectively direct the cooling-air flow from the refrigeration apparatus (110) to the compartments (130, 140). The multiplex damper system (150) comprises a single movable control damper (160) mounted in the cooling-air passage and a drive control system (155) responsive to the cooling demands of the respective compartments and that is coupled to the single control damper (160) so as to selectively dispose the control damper in a plurality of respective air flow positions. The range of air flow positions includes a first compartment-only air flow position, a second compartment-only air flow position, and at least one divided-flow position in which cooling air flow is proportionally directed into both the first and the second compartments.
