Multifunctional storage system having separate cleaning flow passage

Abstract

A multifunctional storage system includes a storage chamber and a machine chamber provided on one side of the storage chamber and in fluid communication with the storage chamber. The system also includes a humidifier configured to generate naturally humidified air with a circulation filter unit; a dehumidifier configured to generate dried air with a heat pump module; a cleaning filter unit configured to purify exterior air; a first flow passage in which the humidifier band the dehumidifier are embedded and configured such that the naturally humidified or dried air flows therethrough; a second flow passage configured such that the exterior air filtered by the cleaning filter unit flows therethrough; and a fan unit configured to circulate air in one direction. The first and second flow passages form flow passages that are independently formed and separated from each other, and formed to be in communication with the fan unit.
