1. A refrigerator, comprising: a refrigerator body having a cold chamber defined therein, and one or more storage chambers disposed in a lower portion of the cold chamber, wherein the one or more storage chambers is in the form of one or more containers, a lowermost one of the one or more storage chambers being disposed adjacent a lower wall of the cold chamber;a cool air generation chamber having a cooler and a fan that supplies cool air mounted therein;a partition plate that partitions the cold chamber and the cool air generation chamber from each other, the partition plate having a main flow channel that guides the cool air supplied by the fan to the cold chamber and at least one cool air hole located between the fan and the main flow channel, through which the cool air is directed to the one or more storage chambers;at least one bypass duct that guides the cool air bypassed through the at least one cool air hole to the one or more storage chambers; anda damper mounted in the cool air generation chamber such that the damper is disposed between the bypass duct and the main flow channel, that selectively opens and closes the main flow channel, wherein the one or more storage chambers is cooled more rapidly by the cool air supplied through the at least one bypass duct when the damper is closed than when the damper is opened, wherein the at least one cool air hole is disposed over the cooler and the lowermost one of the one or more storage chambers is disposed under the cooler, and wherein the at least one bypass duct extends from the at least one cool air hole to the lowermost one of the one or more storage chambers in a vertical direction. 2. The refrigerator according to claim 1, wherein the at least one cool air hole is formed in a shape of a slot lengthened in a direction perpendicular to a direction in which the cool air flows from the fan to the main flow channel. 3. The refrigerator according to claim 1, wherein the at least one bypass duct is disposed at a front surface of the partition plate. 4. The refrigerator according to claim 1, wherein the at least one bypass duct extends from the at least one cool air hole to the lowermost one of the one or more storage chambers along at least one side of the cold chamber. 5. The refrigerator according to claim 1, wherein a central longitudinal axis of the at least one bypass duct extends parallel to a central longitudinal axis of the refrigerator body. 6.

The refrigerator according to claim 6, wherein the at least one bypass duct is disposed at a rear surface of the one or more storage chambers. 8. The refrigerator according to claim 6, wherein the at least one bypass duct is disposed along at least one side of the cold chamber. 9. The refrigerator according to claim 6, wherein the at least one bypass duct is disposed such that the at least one bypass duct communicates with the main flow channel, and wherein some of the cool air flowing along the main flow channel flows to the at least one bypass duct. 10. The refrigerator according to claim 6, further comprising: a communication port formed at the one or more storage chambers that guides an introduction of the cool air in the cold chamber to the one or more storage chambers. 11. The refrigerator according to claim 10, further comprising: a guide hole formed at the at least one bypass duct at a position corresponding to the communication port of the one or more storage chambers that guides the cool air to the communication port. 12. The refrigerator according to claim 6, further comprising: a connection channel that directly interconnects the at least one bypass duct and the one or more storage chambers and guides the cool air. 13. A refrigerator, comprising: a refrigerator body having a cold chamber defined therein, and one or more storage chambers disposed in a lower portion of the cold chamber, wherein the one or more storage chambers is in the form of one or more containers, a lowermost one of the one or more storage chambers being disposed adjacent a lower wall of the cold chamber;a cool air generation chamber having a cooler and a fan that supplies cool air mounted therein;a partition plate that partitions the cold chamber and the cool air generation chamber from each other, the partition plate having a main flow channel that guides the cool air supplied by the fan to the cold chamber; andat least one bypass duct that includes: a first duct disposed in the cool air generation chamber that guides the cool air in a downward direction; anda second duct that is connected to the first duct and extends from the first duct toward the one or more storage chambers, wherein the second duct guides the cool air from the first duct to the lowermost one of one or more storage chambers; anda damper mounted in the cool air generation chamber such that the damper is disposed between the bypass duct and the main flow channel, that selectively opens and closes the main flow channel, wherein the one or more storage chambers is cooled more rapidly by the cool air supplied through the at least one bypass duct when the damper is closed than when the damper is opened, wherein the at least one cool air hole is disposed over the cooler and the lowermost one of the one or more storage chambers is disposed under the cooler, and wherein the at least one bypass duct extends from the at least one cool air hole to the lowermost one of the one or more storage chambers in a vertical direction. 14.
