Patent ID: 7984623

Claim:
A refrigerator comprising: a freezing chamber having a first evaporator and a first fan provided therein; a refrigerating chamber having a second evaporator and a second fan provided therein, wherein the first and second fans are configured to direct cool air generated by the first and second evaporators to the freezing and refrigerating chambers, respectively; and a plurality of cool-air ducts provided in at least one of the freezing or refrigerating chambers, the cool air ducts being configured to provide cool air to at least one of the freezing or refrigerating chambers via operation of the first and second fans, respectively, and wherein the refrigerator further comprises: at least one guide which receives or is coupled to either one of the first or second fans, the at least one guide having a plurality of guide pipelines with first ends in communication with the plurality of cool-air ducts and second ends positioned around said one of the first or second fans, wherein the second ends are closer to said one of the first or second fans than the first ends along respective airflow paths through the guide pipelines, wherein the second ends of the guide pipelines are positioned on different sides of said one of the first or second fans in a spiral pattern, the second end of a first one of the guide pipelines positioned around said one of the first or second fans at a first angle and the second end of a second one of the guide pipelines positioned around said one of the first or second fans at a second angle different from the first angle, wherein the second end of the first one of the guide pipelines is coupled to the second end of the second one of the guide pipelines to form an enclosure around said one of the first or second fans, wherein the second ends of said first and second ones of the guide pipelines are positioned around said one of the first fan or the second fan at the first and second different angles relative to a reference line passing through a center of the fan, wherein the first angle is measured from the reference line to a first point which corresponds to first location where the second end of the first one of the guide pipelines contacts the second end of the second one of the guide pipelines, and wherein the second angle is measured from the reference line to a second point which corresponds to a second location where the second end of the first one of the guide pipelines contacts the second end of the second one of the guide pipelines.
