Abstract
The present invention discloses a refrigerator which can perform direct cooling of circulating cool air by natural convection in a freezing chamber (F) and a refrigerating chamber (R), and which can selectively perform indirect cooling of circulating cool air by forcible convection in the refrigerating chamber. It is like that, frost or condensed water formed in the refrigerating chamber (R) of the direct cooling type refrigerator does not Influence the inside of the refrigerating chamber. In addition, the refrigerator efficiently performs a defrosting operation of the refrigerating chamber (R), sanitarily performs a cooling operation, and maintains uniform cooling performance.
Claims35
A refrigerator, comprising:
- a refrigerator main body in which a freezing chamber and a refrigerating chamber are formed to be partitioned;
- a freezing chamber side evaporator installed at the freezing chamber, for directly cooling the freezing chamber;
- a refrigerating chamber side evaporator installed in direct contact on a rear surface of an inner wall of the refrigerating chamber, for cooling the refrigerating chamber;
- a refrigeration cycle including a compressor, a condenser and an expansion means connected to the freezing chamber side evaporator and the refrigerating chamber side evaporator, and performing a cooling operation around the evaporators by circulating refrigerants;
- a duct being installed on a front surface of the inner wall of the refrigerating chamber to form a cool air circulation passage in an up/down direction, having a suction hole at its one end, and having a plurality of cool air distribution holes at its other side of the suction hole for distributing cool air to the refrigerating chamber;
- an air blowing device installed at the suction hole of the duct, for blowing the air circulated in the refrigerating chamber to pass through the cool air circulation passage;
- and
- a control unit for naturally or forcibly convecting the cool air in the refrigerating chamber by controlling operations of various components including the compressor and the air blowing device.
