COOL AIR OUTLET HOLE OF FREEZING CHAMBER OF REFRIGERATOR

摘要

PURPOSE: A cool air outlet hole of freezing chamber of a refrigerator is provided to prevent the occurrence of vortex in a portion adjacent to a grill vent hole and to make ventilation of cool air efficient by improving the structure of a cool air outlet hole. CONSTITUTION: A cool air heat-exchanged while passing an evaporator(4) is vented in both directions in a cool air passage(60) according to the rotational direction of a blower fan(11) while passing an orifice(51) formed in a shroud(50) by the rotational power of the blower fan. The vented cool air is vented to a freezing chamber(10) by passing a main grill vent hole(71) formed in a grill(700). Herein, the main grill vent hole is separated from the part wherein the blower fan is installed at a certain distance(S=1.5D). The ventilation of the cool air is performed via the entire part of the main grill vent hole. Thereby, a vortex is prevented by removing a vortex occurring when the cool air passes the main grill vent hole.
