A refrigerator includes a main body provided with storage chambers having doors, one of the doors being provided with an opening, the opening having at least one stepped plane; a rack installed in the storage chamber at a height corresponding to that of the lower end of the opening; a sub door to open and close the opening; and a connection member to prevent a height difference between a rear surface of the sub door and the opening. The connection member is configured to slide relative to the sub door to cover the at least one stepped plane, whereby the connection member closes the at least one stepped plane when the sub door is closed, and opens the at least one stepped plane when the sub door is opened so that the rear surface of the sub door and the connection member form substantially a level plane with the rack.

Refrigerator having sub door

A refrigerator having a valve to control the supply of a refrigerant to a plurality of storage chambers and a control method of the same. An opening time rate of the valve is changed based on modes of the storage chambers to control the amount of the refrigerant supplied to the storage chambers, thereby avoiding concentration of the refrigerant in one of the storage chambers and thus preventing refrigerant shortage in the other storage chambers. Also, left and right temperature deviation of each storage chamber is reduced, thereby achieving uniform temperature distribution of each storage chamber.

Refrigerator having a plurality of storage containers and control method of the same

A refrigerator having a sub door which reduces energy loss and a method of manufacturing method the sub door. The refrigerator includes a main body provided with storage chambers formed therein, doors opening and closing the storage chambers, and provided with an opening, a sub door to open and close the opening, and a cooling unit provided on the rear surface of the sub door. When the sub door is opened, cool air of the cooling unit is transmitted to a stored article put on the rear surface of the sub door, and when the sub door is closed, relatively uniform temperature distribution in the storage chamber is achieved and thus storage performance of the refrigerator is improved.
