A refrigerator is disclosed wherein an ion generator is arranged in a cold air duct which supplies cold air to a storage compartment, and a desired portion of the cold air duct is treated for anti-static. The ions from the ion generator are used for the purpose of sterilization and deodorization and are effectively discharged into the storage compartment. The anti-static-treatment of the cold air duct prevents the ions generated from the ion generator from being lost due to static in the cold air duct. The anti-static treatment is carried out by coating polyethylene on a portion of the cold air duct. The cold air duct includes a plurality of uniformly spaced cold air outlets, whereby the ions generated from the ion generator are uniformly distributed into the overall portion of the storage compartment through the cold air outlets.
摘要:
The present invention provides a small and fast zoom system using micromirror array lens (MMAL). Thanks to the fast response and compactness of the MMAL as well as absence of the macroscopic mechanical movements of lenses, the zoom system of the present invention fastens the speed of the zooming and reduces the space and weight for the zoom system. Also the present invention provides magnifying the area not on the optical axis and can compensate the aberration of the zoom system.
