  • Patent number: 5713215
    Abstract: A refrigerator having quick freezing facility is disclosed. The refrigerator includes a body, an evaporator, and a blowing fan. The body has freezing compartment which has a back wall formed with a plurality of cool air discharge openings. The evaporator is disposed adjacently to said cool air discharge openings in a rear part of the body and is tilted backward at a predetermined angle. The blowing fan is disposed in a position near the bottom rear area of the evaporator and blows toward the evaporator to blow cool air produced by the evaporator to the freezing compartment through the air discharge openings. Since the evaporator is disposed near the air discharging openings and the blowing fan blows toward the evaporator, the temperature of the cool air is lowered and then quick freezing is made efficiently.
