DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 1-3. In the first embodiment, the present invention provides a sink device 100 which comprises: a sink 1 including a sink surface 11 and a drainage hole 12, which is disposed on the sink surface 11 and is communicated with a drain pipe 13. The upper edge of the sink surface 11 of the sink 1 is annularly provided with a plurality of water holes 14, which are connected to a water supplying means S. The sink device 100 includes a faucet means 2, which is disposed on the sink 1 and comprises a faucet body 21. The faucet body 21 is provided with a washing outlet 22. In the present embodiment, the washing outlet 22 of the faucet body 21 is communicated with the water supplying means S, i.e., the water source of the faucet body 21 and the plurality of water holes 14 come from the water supplying means S. In other embodiments, the washing outlet 22 of the faucet body 21 can communicate with other water supplying means, so the water source of the faucet body 21 and the plurality of water holes 14 can be independent.

In the present embodiment, a communicating pipe 15 is formed around and inside the sink body of the sink 1, one end of which is connected to the water supplying means S, and the pipe wall of the communicating pipe 15 is communicated with the plurality of water holes 14. By way of this, the water coming from the water supplying means S could flow through the communicating pipe 15 and come out from the plurality of water holes 14. But the present invention is not limited to this. The plurality of water holes 14 could connect to the water supplying means S directly, and do not have to flow through the communicating pipe 15. Since the plurality of water holes 14 are disposed on the upper edge of the sink surface 11, the water flow which comes out from the plurality of water holes 14 have bigger gravitational potential energy and thus possesses greater impact force. Thus, the water current is easy to flow through the entire sink surface 11 and bring the stains on the sink surface 11 into the drain pipe 13. Preferably, the distance between each water hole 14 can be set according to the radian measure of the sink surface 11 and the size of the hole diameter of the plurality of water holes 14, and then the plurality of water holes 14 are annularly disposed on the upper edge of the sink surface 11. By this way, the water current can flow through the sink surface 11 evenly and make the sanitary function better.

By the structure above, the water coming form the water supplying means S flows out of a plurality of annularly arranged water holes 14 on the upper edge of the sink surface 11 of the sink 1, so the impact force of the water current can scour the sink surface 11 of the sink 1 and make the stains hard to deposit on the sink surface 11. Therefore, the sink device 100 of the present invention has the ability of self-cleaning, and thus is easy to maintain cleanliness, saving the time and effort brushing the sink device 100, providing better sanitary environment.

Please refer to FIG. 3. The sink device 100 of the first embodiment further comprises a filtering means 4, a heating means 5 and a pressurizing means 6, wherein the filtering means 4 is communicated with the water supplying means S, the heating means 5 is thermally connected with the filtering means 4, and the pressurizing means 6 is communicated between the heating means 5 and the plurality of water holes 14. The filtering means 4 is a mechanism with filtering function. The heating means 5 is a mechanism which supplies thermal energy. The pressurizing means 6 is a pressure pump or a motor. The water coming from the water supplying means S will firstly be filtered by the filtering means 4 to remove the impurities, so the water used to clean the sink surface 11 will not form limescale on the sink surface 11 easily. The filtered water is then heated by the heating means 5 so as to make water-soluble stains on the sink surface 11 dissolved in water more easily. Then the water current is pressurized by the pressurizing means 6 to flow out from the plurality of water holes 14, by which the impact force of the water current for scouring the sink surface 11 is enhanced. By the structure above, the cleaning function of the sink surface 11 of the sink device 100 can be further enhanced. But the filtering means 4, the heating means 5, and the pressurizing means 6 are not necessarily needed to be disposed simultaneously. They can be provided individually based on demands and cost considerations. The sink device 100 of the first embodiment further comprises a detergent storage means 7, which communicates with a disposed detergent outlet. The detergent storage means 7 is used to store and transport detergents. In the present embodiment, the detergent storage means 7 is communicated with the plurality of water holes 14, making the plurality of water holes 14 the detergents outlets. Each of the water holes 14 includes a detergent delivery end and a clear water delivery end, wherein the clear water delivery end is disposed above the detergent delivery end, and the detergent and clear water are delivered in sequence. While water flows out from the clear water delivery end, the detergent delivery end is also cleaned, by which the detergent together with the water flown out of the water supplying means S come out from the plurality of water holes 14 and flow through the sink surface 11. Therefore, the self-cleaning effect of the sink surface 11 is enhanced.

Please refer to FIGS. 4-6.
