1. A multi-functional storage system, comprising:
a storage compartment;
a circulation flow path positioned at the rear of the storage compartment, and including an inlet end and an outlet end each communicating with the storage compartment, through which circulating air flows; and
a flow path inlet for introducing the circulating air into the circulation flow path, the flow path inlet being positioned between the storage compartment and the circulation flow path and in communication with the inlet end of the circulation flow path, wherein the circulation flow path is formed to extend upward, and
wherein the flow path inlet is a space formed between a rear surface of the storage compartment and a front surface of the circulation flow path and including at least a portion tapered upward,
wherein the flow path inlet is formed in a shape corresponding to shapes of the rear surface of the storage compartment and the front surface of the circulation flow path, and
a horizontal cross-sectional area of an upper portion is formed to be smaller than a horizontal cross-sectional area of a lower portion,
wherein the circulation flow path includes a plurality of fans communicating with the flow path inlet, the plurality of fans including:
a first fan communicating with the lower portion of the flow path inlet; and
a second fan communicating with the upper portion of the flow path inlet, and
the first fan and the second fan are configured to suck in the circulating air introduced into the flow path inlet in a horizontal direction and supply it onto the circulation flow path,
wherein the rear surface of the storage compartment includes an inclined portion including a portion facing the second fan and configured to be inclined toward the front surface of the circulation flow path, and
the flow path inlet is formed so as to be decreased in cross-sectional area by the inclined portion in the horizontal direction toward the upper side,
wherein an inclination angle of the inclined portion toward the circulation flow path varies according to an output of each of the first fan and the second fan.
