Abstract
A cool air supplying apparatus of a refrigerator comprises a guide passage formed at a rear wall of a refrigerating chamber and provided with a plurality of discharge ports towards the refrigerating chamber for guiding cool air to a rear side of the refrigerating chamber, and a direction control unit installed at the guide passage for selectively opening and closing the discharge ports in order to control a discharge direction of cool air discharged into the refrigerating chamber.
Claims25
A cool air supplying apparatus of a refrigerator, comprising:
- a guide passage formed at a rear wall of a refrigerating chamber and provided with a plurality of discharge ports towards the refrigerating chamber for guiding cool air to a rear side of the refrigerating chamber, wherein the plurality of discharge ports are formed at a distance from each other in a widthwise direction of the guide passage;
- temperature sensors installed at each position of the refrigerating chamber, for detecting temperature inside the refrigerating chamber;
- a direction control plate disposed near a surface of the guide passage where the discharge ports are formed and moving along a widthwise direction of the guide passage, for selectively opening and closing a selection of the discharge ports to control a direction of cool air discharged into the refrigerating chamber;
- a control plate driving unit for moving the direction control plate;
- and
- a control unit for automatically controlling the control plate driving unit according to temperature inside the refrigerating chamber detected by the temperature sensors.
