ABSTRACT:
A tableware washing apparatus is adapted to allow garbage deposited to tableware to be washed off by washing water injected toward the inside of a shower sink, and the garbage dropped into the inside of the shower sink to be washed out with the washing water. A cross-sectional shape of the shower sink includes a bottom wall having a large curvature, a first sidewall rising substantially vertically from one of opposite ends of the bottom wall, and a second sidewall rising from the other end of the bottom wall and having a curvature smaller than that of the bottom wall. A sectional area of a flow path at the bottom wall is small, as compared with a shower sink having a quadrilateral section or a circular section. Therefore, even if the flow rate of the washing water is reduced to save water, the flow speed of the washing water flowing on the bottom wall can be raised to effectively wash out the garbage.
