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.

Claims

1. An article washing apparatus for a shower sink;

comprising;

a sink shower including a bottom wall having a large curvature, a first sidewall rising substantially vertically from one of opposite ends of the bottom wall, a second sidewall rising from the other of the opposite ends of the bottom wall and having a curvature smaller than that of the bottom wall, and a flat reflecting plate facing obliquely downward disposed at an upper part of the second side wall; and

a nozzle for injecting washing water toward the flat reflecting plate of the shower sink in order to strike waste deposited on an article disposed in a path of the injected washing water, the waste dropping into the inside of the shower sink being washed out with the washing water.

2. The article washing apparatus according to claim 1, wherein the nozzle for injecting the washing water is provided at an upper portion of the first sidewall.

3. The article washing apparatus according to claim 2, wherein a water reservoir is provided behind the reflecting plate so that the washing water is supplied from the water reservoir to the second sidewall.

4. The article washing apparatus according to claim 3, wherein the water reservoir has a slit provided in its bottom for supplying the washing water to the second sidewall.

5. The article washing apparatus according to claim 1, wherein the article is tableware and the waste is garbage.

6. The article washing apparatus according to claim 5, wherein a person holding the tableware stands on a side of the first sidewall of the shower sink.

7. The article washing apparatus according to claim 6, wherein the washing water is injected when it is detected that the person holding the tableware has approached the first sidewall of the shower sink.

8. The article washing apparatus according to claim 1, the shower sink further comprising a third side wall and a fourth side wall extending substantially perpendicular to the first and the second side walls, each of the third and the fourth side walls being provided with water pouring ports.

9. The article washing apparatus according to claim 8, wherein the water pouring ports are disposed lower in the shower sink than the nozzle.

10. The article washing apparatus according to claim 1, further comprising a drainage tub attached a low part of the bottom side wall and extending rearwardly and downwardly under the second side wall.

11. An article washing apparatus adapted to allow waste to be washed off by washing water injected toward the inside of a shower sink, and the waste dropped into the inside of the shower sink to be washed out with the washing water,

wherein 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,

wherein a nozzle for injecting the washing water is provided at an upper portion of the first sidewall, and a flat reflecting plate facing obliquely downwards is disposed at an upper portion of the second sidewall, to which the washing water injected from the nozzle is directed.

12. The article washing apparatus according to claim 11, wherein the washing water is injected in substantially a horizontal direction toward the flat reflecting plate.

13. The article washing apparatus according to claim 11, wherein a water reservoir is provided behind the reflecting plate so that the washing water is supplied from the water reservoir to the second sidewall.

14. The article washing apparatus according to claim 13, wherein the water reservoir has a slit provided in its bottom for supplying the washing water to the second sidewall.

15. The article washing apparatus according to claim 11, wherein the article is tableware and the waste is garbage.

16. The article washing apparatus according to claim 15, wherein a person holding the tableware stands on a side of the first sidewall of the shower sink.

17. The article washing apparatus according to claim 16, wherein the washing water is injected when it is detected that the person holding the tableware has approached the first sidewall of the shower sink.

18. The article washing apparatus according to claim 11, the shower sink further comprising a third side wall and a fourth side wall extending substantially perpendicular to the first and the second side walls, each of the third and the fourth side walls being provided with water pouring ports.

19. The article washing apparatus according to claim 18, wherein the water pouring ports are disposed lower in the shower sink than the nozzle.

20. The article washing apparatus according to claim 11, further comprising a drainage tub attached a low part of the bottom side wall and extending rearwardly and downwardly under the second side wall.
