Abstract
A refrigerator including a refrigerator main body having a refrigerating chamber therein, a cold air passage duct provided within the refrigerator main body and having a cold air passage therein to discharge the cold air into the refrigerating chamber, a control case attached 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 knob provided between the cold air passage duct and the control case and attached to the control case to be reciprocally movable in one direction, the knob opening and closing at least part of the cold air discharge opening.
Claims15
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 passage duct, the control case including a cold air discharge opening through which the cold air is discharged;
- and
- a knob provided between the cold air passage duct and the control case, the knob being reciprocally movable in one direction to open and close at least a part of the cold air discharge opening,
- wherein the control case comprises a pressing protrusion to press against a lower end portion of the knob, the pressing protrusion provided below the cold air discharge opening and protruding toward the cold air passage duct,
- wherein the knob comprises a flow rate adjusting portion to adjust an opening and closing amount of the cold air discharge opening in response to being pressed by the pressing protrusion,
- wherein the flow rate adjusting portion comprises:
- a plurality of protrusions disposed at the lower end portion of the knob that are spaced apart from one another by a preset distance, and
- a slot cut off to enable an elastic transformation of the lower end portion of the knob when the protrusions are pressed by the pressing protrusion,
- wherein the control case further comprises a knob coupling portion formed between a first side and a second side of the cold air discharge opening, the knob coupling portion configured to slidably guide a movement of the knob, and
- wherein the knob comprises:
- a stopping portion being formed having a bend from an upper end portion of the knob toward the control case so as to be slidably stopped in the knob coupling portion;
- and
- a cut portion being formed by having at least part of an upper portion of the knob cut off, whereby the cut portion is communicably coupled with the cold air discharge opening such that the cold air is discharged by opening at least part of one of the first side or the second side of the cold air discharge opening.
