Patent ID: 8590334

Claim:
A storing device for a refrigerator, comprising: a drawer that is movable in and out of the refrigerator; a drawer cover formed of a transparent or translucent material and selectively covering an open upper surface of the drawer; and a plurality of water collecting recesses that are recessed from a lower surface of the drawer cover and have variable transparency according to collecting of moisture to show an inner moisture state of the drawer, wherein the lower surface of the drawer cover defined within each of the water collecting recesses is inclined upwardly, and wherein the inclined lower surface of the drawer cover is configured such that, when water is absent from the water collecting recesses, light is refracted through the inclined lower surface to make the drawer cover at least partially opaque and, as water collects in the water collecting recesses, light passes through the inclined lower surface with less refraction, thereby increasing transparency of the drawer cover.
