A Kimchi storage facility having a non-contact power supply device is provided. The Kimchi storage facility includes a main body provided with a storage room storing Kimchi, and a mechanic room where a power supply is installed, a door opening and closing the storage room, and a non-contact power supply device which is installed between the door and the main body, to supply power by an electromagnetic induction. A magnetic levitation unit is provided in a fan accommodation case and rotated in a magnetic levitation rotating manner by induced current supplied via the non-contact power supply device, to thus forcedly circulate cooled air in the storage room. Here, a rotating fan is installed in the lower portion of the door at the state where the rotating fan is accommodated in the fan accommodation case, or a driving motor and a fan which are connected with the non-contact power supply device by wire are installed in the lower portion of the door. Thus, the rotating fan is rotated in a magnetic levitation rotation manner, or the driving motor is driven to make the fan rotate, by the induced current supplied via the non-contact power supply device. Accordingly, the cooled air in the storage room can be forcedly circulated to thus improve deviation of temperature in the storage facility.

What is claimed is: 1. A storage facility keeping in store foods such as Kimchi which is the Korean preserved vegetables, which comprises a main body provided with a storage room storing Kimchi, and a mechanic room where a power supply is installed, and a door opening and closing the storage room, the storage facility comprising: a non-contact power supply device having a first coil unit which receives power from the power supply and transfers power by electromagnetic induction, which is mounted in the upper portion of the main body, and a second coil unit which is mounted in the door in correspondence to the first coil unit, in which the non-contact power supply device is mounted correspondingly between the main body and the door; a driving motor which is installed in the door and receives induced current via the non-contact power supply device and is driven; and a fan which rotates by the driving force of the driving motor and forcedly circulates cold air in the storage chamber, which is installed on the bottom of the door. 2. The storage facility of claim 1, wherein the first coil unit in the non-contact power supply device comprises a first printed circuit board (PCB) substrate which is accommodated in a space enclosed by a lower protection cover at one side of the upper portion of the main body, and a bobbin which is connected to the first PCB substrate and around which coil is wound, so as to be connected to the power supply via a cable to receive power, and the second coil unit in the non-contact power supply device comprises a second printed circuit board (PCB) substrate which is accommodated in a space enclosed by an upper protection cover installed in the door so that induced current can be generated by electromagnetic induction against the first coil unit, and a bobbin which is connected to the second PCB substrate and around which coil is wound. 3. The storage facility of claim 2, wherein a shield plate is installed in the lower portion of the bobbin in the first coil unit. 4. A storage facility keeping in store foods such as Kimchi which is the Korean preserved vegetables, which comprises a main body partitioned with a storage room storing Kimchi, and a mechanic room where a power supply is installed, and a door opening and closing the storage room, the storage facility comprising: a non-contact power supply device having a first coil unit which receives power from the power supply and transfers power by electromagnetic induction, which is mounted in the upper portion of the main body, and a second coil unit which is mounted in the door in correspondence to the first coil unit; and a rotating fan which is installed on the bottom of the door at a state where the rotating fan is mounted in a fan accommodation case provided with a magnetic levitation unit so as to rotate in a magnetic levitation rotation manner by the induced current supplied via the non-contact power supply device. 5. The storage facility of claim 4, wherein the magnetic levitation unit comprises: a plurality of electromagnets which are connected to the second coil unit in the non-contact power supply device by wire and installed in the fan accommodation case at a predetermined interval to generate an electromagnetic force at a state where polarities of N-pole and S-pole are separated individually; a third permanent magnet which is distant from the electromagnets to have a space where the rotating fan can be installed, and which is installed on the central inner wall of the bottom of the fan accommodation case; a first permanent magnet which generates a repulsive force against the plurality of electromagnets in which N-poles and S-poles which are integrally mounted in one side of the rotating fan are repeatedly magnetized so that the rotating fan can receive a rotational force; and a second permanent magnet which generates a repulsive force against the third permanent magnet and which is integrally mounted on the other side surface of the rotating fan which opposes the first permanent magnet. 6. The storage facility of claim 5, wherein the rotating fan comprises: a cylindrical body on both sides of which the first permanent magnet and the second permanent magnet are mounted, a wing portion having a plurality of rotating wings which are formed on the outer circumferential surface of the cylindrical body; and a rotating axis which protrudes at the center of the cylindrical body, so as to be freely rotated by magnetic levitation in the fan accommodation case. 7. The storage facility of claim 6, wherein the fan accommodation case comprises: a cap-shaped fan cover in which the rotating fan is accommodated and supported, on the bottom of which a plurality of inhaling holes are formed so that cold air in the storage chamber can be inhaled and discharged, on the lateral surfaces of which a plurality of discharging holes are formed, and on the bottom of which the third permanent magnet is mounted on the central inner wall thereof; and a base cover which includes a cover surface which blocks the upper opening of the fan cover and a support hole through which the rotational axis of the rotating fan is inserted freely rotatably at the center of the cover surface, in which an electromagnets accommodation unit accommodating the electromagnets of the magnetic levitation unit is provided on the cover surface facing the support hole and which is fitted with the fan cover and mounted in a mount portion provided on the bottom of the door. 8. The storage facility of claim 7, wherein a flange-shaped fitting guide is provided on the outer circumferential surface of the electromagnets accommodation portion in the base cover, and the base cover is turned and fitted with the guide fitting portion provided in the mount portion on the bottom of the door via the fitting guide. 9.
