A sink having an invisible drainage device

Abstract

A sink having an invisible drainage device, comprising an overflow table ( 1 ), an overflow basin ( 2 ), an auxiliary water tank ( 3 ), and a water retaining component; the overflow basin ( 2 ) is embedded within the overflow table ( 1 ), and the auxiliary water tank ( 3 ) is in communication with the overflow basin ( 2 ); the water retaining component comprises a limiting plate ( 21 ), a movable water retaining plate ( 22 ) and a limiting block ( 23 ), the limiting plate ( 21 ) being fixedly disposed above a water outlet of the overflow basin ( 2 ), and the movable water retaining plate ( 22 ) being movably provided at a bottom portion of the limiting plate ( 21 ) and being located at a position at which the overflow basin ( 2 ) and the auxiliary water tank ( 3 ) communicate; the limiting plate ( 21 ) is disposed at a lower mouth of the overflow basin ( 2 ), and a bottom portion of the auxiliary water tank ( 3 ) is provided with a water outlet component. The overflow table ( 1 ) and the overflow basin ( 2 ) are integrally and seamlessly jointed so as to resolve persistent shortcomings such as dirt hiding, bacterium breeding and cleaning being impossible between traditional basins and tables. Moreover, problems such as dirty corners, odor leakage and cleaning being impossible are completely solved, being convenient and safe for users, while setting the mind at ease and alleviating worry. Meanwhile, the overall aesthetics are greatly improved, the sink being more beautiful and more harmonious.
