摘要： A refrigerator is divided into a storage compartment and an air duct in a thermal insulating housing. The cold air for use of the thermal exchange with a cooler in the duct circulates in the storage compartment by a fan. The refrigerator has an ultraviolet ray irradiating device capable of irradiating ultraviolet rays. The ultraviolet ray irradiating device is installed at the inflow side of cooler, but separated from the cooler, so that the ultraviolet rays irradiate the duct by the ultraviolet ray irradiating device. Therefore, various germs such as bacteria or molds in the refrigerator can be prevented from growth, and the refrigerator can be deodorized.

摘要： A refrigerator is provided. The refrigerator comprises an ultraviolet discharging lamp, for irradiating ultraviolet rays to an air duct inside the refrigerator, and irradiating a visible light to a cold storage compartment of the refrigerator; a light catalyst filter, installed in the air duct and activated by the ultraviolet rays; a fan for forming an air curtain when a door of the cold storage compartment of the refrigerator is opened; and a controlling device for lighting the ultraviolet discharging lamp when the door of the cold storage compartment of the refrigerator is opened. In addition, the refrigerator can further comprise an operating device for setting or disabling an antimicrobial mode of the refrigerator; and a controlling device for lighting the ultraviolet discharging lamp for a preset interval, and turning off the ultraviolet discharging lamp when a door of the refrigerator is opened, when the antimicrobial mode is disabled.
