ARRANGEMENT FOR THE FORCED AIR CIRCULATION IN REFRIGERATORS AND FREEZERS

摘要

An arrangement for the forced air circulation in refrigerators and freezers, whose cabinet (10) defines at least one compartment (20, 30), a respective door (21, 31), and an air-cooling chamber (11) lodging an evaporator (12) and from which the compartment is supplied with a forced cooling airflow. The arrangement comprises: at least one suction duct (40), incorporated to the door (21, 31) and which is provided with air inlets (41), opened to the interior of the respective compartment (20, 30), and with at least one air outlet (42) turned to the interior of the cabinet (10). A return fan (50) is mounted so as to draw the air from different levels of the front part of the compartment, and to form inside the suction duct (40) a return airflow that is directed to the air outlet (42) of the suction duct (40).
