REFRIGERATOR HAVING COOLING SYSTEM OF WHICH COLD STORAGE CHAMBER AND FREEZING CHAMBER ARE SEPARATED

摘要

PURPOSE: A refrigerator having a cooling system is provided to prevent the deterioration of food freshness and storage state generated by the inflow of humidity or smell into a freezing chamber by preventing cold air circulating a freezing chamber and a cold storage chamber from being mixed. CONSTITUTION: Cold air for cooling foods in a cold storage chamber is flowed in an intake duct(11) through an intake(23) by the absorption force of a ventilation fan(9) and reaches an evaporator(4). The cooled cold air rises along with a vertical part of the intake duct(11), comes to an exhaust duct(13) through a vent hole(19), flows downward along with the exhaust duct and flows in the cold storage chamber through plural exhaust holes(25). The cold air circulating the freezing chamber is flowed in both horizontal parts of the intake duct(12) for the freezing chamber through an intake hole(27). The cold air reaching the evaporator rises upward along with the vertical part of the intake duct after cooled by the evaporator. Then, the cold air is flowed in the freezing chamber through the vent hole from the exhaust duct and completes one cycle of circulation to the freezing chamber.
