  • Patent number: 11085693
    Abstract: The present invention discloses an air volume adjustment device for a refrigerator. The air volume adjustment device comprises: a fan capable of introducing cold air from an evaporator into the first air inlet cavity and the second air inlet cavity; a baffle arranged between a first air inlet cavity of a first compartment and a second air inlet cavity of a second compartment, which is capable of moving among a plurality of positions to adjust the volume of air entering the first air inlet cavity and the second air inlet cavity; and an operating knob and a potentiometer which are connected to the front side and the rear side of the baffle, respectively. The operating knob is capable of operably driving the baffle to move. The potentiometer transfers an electrical signal corresponding to a position of the baffle to the controller for controlling the fan or the compressor.

  • Publication number: 20190277559
    Abstract: Provided is a single-system air-cooled refrigerator (100), comprising a refrigerator compartment (10) and a freezer compartment (20). Also comprised are a first air passage (30) and a second air passage (40) which are separated from each other and connect the refrigerator compartment (10) and the freezer compartment (20), a first damper (31) and a second damper (41) that respectively open and close the first air passage (30) and the second air passage (40), and a refrigeration system and a control system. The control system is used to control the opening and closing of the first damper (31) and the second damper (41) so as to realize a first mode, a second mode and a third mode of operation of the refrigerator (100). The first operating mode is that neither the freezer compartment (20) nor the refrigerator compartment (10) are switched.
