Abstract
A refrigerator a duct arranged to partition an inner space of a storage chamber body into a storage chamber and an air flow channel, wherein the duct has an ejection hole defined therein; a roll-bond evaporator disposed in the air flow channel, wherein the roll-bond evaporator has a top and a bottom, a left end and a right end; a blowing fan configured to draw air from the storage chamber to blow the air into the air flow channel; and a defrost sensor closer to one of the top and bottom than the other of the top and the bottom, wherein said one is closer to the blowing fan than the other, wherein the sensor is closer to one of the left end and the right end than the other of the left end and the right end.
Claims23
A refrigerator comprising:
- a cabinet comprising an outer case and an inner case provided in the outer case to define a storage space, the inner case including side walls and a rear wall;
- a duct provided at a front side of the rear wall, the duct being formed with an ejection hole through which an air is discharged to the storage space;
- an air flow channel provided between the rear wall of the inner case and the duct;
- an evaporator provided in the air flow channel, the evaporator including a first evaporator and a second evaporator spaced apart from the first evaporator rearward;
- a blowing fan provided in the air flow channel and configured to draw the air from the storage space and to provide the air into the evaporator;
- and
- a defrost sensor provided in a region of the air flow channel defined between the first and the second evaporators,
- wherein each of the first and second evaporator comprises a pair of thermal transfer plates and a refrigerant channel formed between the pair of thermal transfer plates, and
- wherein the defrost sensor is disposed at a surface of one of the pair of thermal transfer plates of the first evaporator or the second evaporator.
