Abstract
An air flow controlling device for refrigerators and freezers, comprising an evaporator (3) in selective fluid communication with at least two air flow heating environments (1, 2, 4), said device comprising an inlet nozzle (12) in fluid communication with a respective airflow heating environment (1, 2, 4), and an outlet nozzle (13) in fluid communication with the evaporator (3), and a respective obturator (20), which is operatively associated with the inlet and outlet nozzles (12, 13) and displaceable between opening and closing positions, respectively permitting and blocking the fluid communication between said inlet and outlet nozzles (12, 13).
Claims14
An air flow controlling device for refrigerators and freezers, comprising at least two air flow heating environments (1, 2, 4) and an evaporator (3) positioned externally to said air flow heating environments (1, 2, 4) and in selective fluid communication therewith, characterized in that it comprises, for each air flow heating environment (1, 2, 4), a respective inlet nozzle (12) in fluid communication with the respective air flow heating environment (1, 2, 4), and a respective outlet nozzle (13) in fluid communication with the evaporator (3) and a respective obturator (20), which is operatively associated with the inlet and outlet nozzles (12, 13) and affixed to a respective shaft portion rotating between opening and closing positions, respectively permitting and blocking the fluid communication between said inlet and outlet nozzles (12, 13), said shaft portions of the obturators (20) forming a single common shaft (30), which is rotatively driven by a motor unit commanded by a control unit.
