Abstract
A refrigerator including a refrigerator main body having a refrigerating chamber therein, a cold air passage duct disposed within the refrigerator main body and provided with a cold air passage therein to discharge the cold air into the refrigerating chamber, a control case coupled to one surface of the cold air discharge duct and having a cold air discharge opening through which the cold air is discharged, and a shutter disposed between the cold air passage duct and the control case, and reciprocally movable in one direction to open and close at least part of the cold air discharge opening, and a knob link rotatably connected to the cold air passage duct to press the shutter such that the shutter is reciprocally movable.
Claims16
A refrigerator comprising:
- a main body having a refrigerating chamber therein;
- a cold air passage duct disposed within the main body, the cold air passage duct including a cold air passage to discharge cold air into the refrigerating chamber;
- a control case attached at one surface of the cold air discharge duct, the control case including a cold air discharge opening through which the cold air is discharged;
- a shutter provided between the cold air passage duct and the control case, the shutter being reciprocally movable in one direction to open and close at least a part of the cold air discharge opening;
- and
- a knob link rotatably connected to the cold air passage duct to press against the shutter such that the shutter is reciprocally movable,
- wherein the knob link comprises:
- a link body having a rotation shaft, the link body being connected to the cold air passage duct by the rotation shaft to be reciprocally rotatable by a predetermined distance,
- a pressing portion provided at a first end portion of the link body that is accommodated in a part of the shutter, the pressing portion to press against the shutter to be reciprocally movable in the one direction, and
- a knob formed on a second end portion of the link body opposite to the first end portion, whereby at least a portion of the knob is externally exposed through the control case to be manipulated by a user,
- wherein the cold air passage duct comprises a dividing portion that divides the cold air discharge opening into first and second cold air discharge openings, the dividing portion extends from upper to lower portions of the cold air discharge opening between the first and second cold air discharge openings,
- wherein the shutter comprises a communicating portion, the communicating portion being a cut-off portion formed at an upper side of the shutter that communicates with the cold air discharge opening such that at least part of one of the first and second cold air discharge openings are open to discharge cold air, and
- wherein the first and second cold air discharge openings have the same area in a state of being opened and closed by the shutter thereby allowing cold air to be uniformly supplied into the refrigerating chamber through the first and second cold air discharge openings.
