SINK

PROBLEM TO BE SOLVED: To provide a sink capable of preventing water from remaining on its bottom surface, completely flowing water into its drain port, and draining water without allowing water to remain on the upper surface of its drain cover. SOLUTION: The bottom surface of the sink is formed by recessing it to a plurality of tilted flat surfaces 8a, 8b, 8c. Each tilted flat surface is downwardly tilted toward the drain port disposed at the rear end thereof in the depth direction. Recessed lines 7a, 7b between the tilted flat surfaces are formed toward the drain port. The tilted flat surfaces of the bottom surface are formed on the drain cover 9 fitted into the drain port. The plurality of tilted flat surfaces 12a, 12b, 12c and the recessed lines 13a, 13b are formed in the extensions of the recessed lines. COPYRIGHT: (C)2008,JPO&INPIT
