Abstract

A refrigerator includes a compressor to compress refrigerant, a condenser to liquefy the refrigerant supplied from the compressor, a capillary tube to decompress and expand the refrigerant supplied from the condenser, an evaporator to vaporize the refrigerant supplied from the capillary tube, a shutoff valve installed at an inlet of the capillary tube so as to prevent the refrigerant in the condenser during stoppage of the compressor from being moved to the evaporator, and a control unit to enable the shutoff valve to be blocked together so as to prevent movement of the refrigerant from the condenser to the evaporator during stoppage of the compressor, and to enable the shutoff valve to be opened together so as to move the refrigerant from the condenser to the evaporator during starting of the compressor.

Claims (20)

1. A refrigerator comprising:

a main body including a storage chamber;

a door to open and close the storage chamber; and

dykes protruding from both ends of an inside surface of the door while having a partition wall shape,

wherein air exhaust holes are formed at a gasket mounting portion of a door panel to form the door and the dykes.

2. The refrigerator according to claim 1 , wherein edge caps are formed at a first upper surface frame which defines an outer case of the main body.

3. The refrigerator according to claim 1 , wherein the air exhaust holes are formed at a dyke forming portion of the door panel.

4. The refrigerator according to claim 1 , wherein:

the door is coupled, at upper, lower, and opposite side surfaces thereof, with upper, lower, and side surface chassis, respectively; and

when the upper surface chassis is assembled with the side surface chassis, the respective side surface chassis are bent toward the upper surface chassis at edges of the door so as to be assembled with the upper surface chassis at the upper surface of the door.

5. The refrigerator according to claim 4 , wherein when the upper surface chassis is assembled with the side surface chassis, the upper surface chassis is bent toward the side surface chassis at the edges of the door so as to be assembled with the side surface chassis at the opposite side surfaces of the door.

6. The refrigerator according to claim 4 , wherein when the lower surface chassis is assembled with the side surface chassis, the respective side surface chassis are bent toward the lower surface chassis at the edges of the door so as to be assembled with the lower surface chassis at the lower surface of the door.

7. The refrigerator according to claim 4 , wherein when the lower surface chassis is assembled with the side surface chassis, the lower surface chassis is bent toward the side surface chassis at the edges of the door so as to be assembled with the side surface chassis at the opposite side surfaces of the door.

8. A refrigerator comprising:

a main body including a storage chamber;

a door to open and close the storage chamber; and

dykes protruding from both ends of an inside surface of the door while having a partition wall shape, wherein:

the door is provided, at upper and lower surfaces thereof, with a door cap;

the door cap is formed with air exhaust holes and an air trap; and

the air trap is filled with a foam solution leaked during a foam process, and air is discharged to the outside through the air exhaust holes.
