The illumination portion 610 is disposed in the storage area 400 and configured to illuminate the storage area 400; the sterilizing part 620 is connected to the illuminating part 610 and configured to sterilize the storage area 400. Like this, provide the illumination through illumination portion 610 for the food that stores in the storage area 400, shine storage area 400 internal environment and the food of storing through sterilization portion 620, disinfect storage area 400 internal environment and the food of storing, when being convenient for show the user with the food that stores in the storage area 400 and watch, keep the health of the food that stores in the storage area 400, can be better carry out temporary storage to food.

Optionally, the lighting part 610 is an LED tube. Thus, the LED light is easily obtained, and the illumination effect is good, so that the illumination portion 610 can illuminate the storage area 400 better.

Alternatively, the sterilization part 620 is an ultraviolet lamp. Thus, the ultraviolet light is easily obtained, and the sterilization effect is good, so that the sterilization part 620 can better sterilize the internal environment of the storage area 400 and the stored food.

Optionally, the light device 600 further comprises: the switch 630 is configured to turn off the lamp 600 when the opening 220 of the housing 200 is separated from the sealing groove 230, and turn on the lamp 600 when the opening 220 of the housing 200 is caught in the sealing groove 230. Thus, when the cover 200 covers the storage area 400 and the opening 220 of the cover 200 is clamped into the sealing groove 230, the lighting device 600 is turned on to illuminate and sterilize the internal environment of the storage area 400 and the stored food, and when the cover 200 is turned over or taken up and the opening 220 of the cover 200 is separated from the sealing groove 230, the lighting device 600 is turned off, so that the energy consumption is reduced, and the user can be prevented from being hurt by the direct irradiation of the lighting device 600.

Optionally, the switch 630 is disposed within the sealing groove 230. Thus, when the cover 200 covers the storage area 400, the opening 220 of the cover 200 is clamped into the sealing groove 230, the switch 630 senses that the opening 220 of the cover 200 approaches, the switch 630 is in an open state, the lighting device 600 is turned on to illuminate and sterilize the internal environment of the storage area 400 and stored food, when the cover 200 is turned over or taken up, the opening 220 of the cover 200 is separated from the sealing groove 230, the switch 630 senses that the opening 220 of the cover 200 is far away, and the switch 630 is in a closed state, and the lighting device 600 is turned off accordingly.

Optionally, switch 630 is an infrared photoelectric switch. Like this, infrared photoelectric switch opens light device 600 for the open mode when sensing that housing 200 is close, closes light device 600 for the closed mode when sensing that housing 200 is far away from, and easily obtains, has reduced manufacturing cost.
