Abstract
A refrigerator includes a heat exchange chamber, first inlets arranged on side surfaces of a first storage chamber and configured to introduce cold air in the first storage chamber into the heat exchange chamber, and second inlets arranged on side surfaces of a second storage chamber and configured to introduce cold air in the second storage chamber into the heat exchange chamber.
Claims16
A refrigerator comprising
- a first storage chamber;
- a second storage chamber arranged below the first storage chamber and controlled to have a temperature that is different from a temperature of the first storage chamber;
- a heat exchange chamber arranged below the first storage chamber and configured to cool air that is cycled through the first storage chamber and the second storage chamber;
- a fan arranged on a first side of the heat exchange chamber and configured to blow cold air from the heat exchange chamber to the first and second storage chambers;
- an evaporator arranged in the heat exchange chamber and including refrigerant pipes through which refrigerant flows and fins configured to promote heat exchange between the refrigerant pipes and the air;
- an evaporator case including a first cover that covers an upper side of the evaporator and a second cover that supports a lower side of the evaporator, the first cover and second cover being configured to define the heat exchange chamber;
- at least one first duct coupler formed at a lateral side surface of the first cover;
- at least one discharge duct coupled to the at least one first duct coupler and having at least one first inlet arranged in the first storage chamber, the at least one discharge duct being configured to allow air flowing into the at least one first inlet to be introduced into the heat exchange chamber through the at least one first duct coupler;
- at least one second, inlet formed at lateral side surface of the second cover and arranged in the second storage chamber, the at least one second inlet being configured to allow air from the second storage chamber to be introduced into the heat exchange chamber,
- wherein a first side of the evaporator is adjacent to the at least one first inlet or the at least one second inlet to allow the air introduced through the at least one first inlet or the at least one second inlet to be guided to the first side of the evaporator, and located upstream of the cold air flowing toward the fan and a central portion of the evaporator is located downstream of the cold air flowing toward the fan, and
- wherein the at least one second inlet is located closer to a front of the refrigerator than the at least one first duct coupler.
