Vortex type drainage structure

The utility model discloses a vortex type drainage structure which comprises a tank body, a liquid outlet is formed in a bottom plate in the tank body, and a vortex structure is arranged on the liquidoutlet. According to the utility model, the water outlet of the tank body is processed; a circle of spiral groove which rotates clockwise or anticlockwise is formed in the periphery of the water outlet; in the liquid discharging process, due to the influence of flow guiding of the grooves between the vortex blades, liquid in the water discharging opening can easily form vortexes, air in the pipeline is discharged upwards from the centers of the vortexes after the vortexes are formed, meanwhile, certain negative pressure is formed in the pipeline, and the liquid discharging speed can be increased. 本实用新型公开了一种漩涡式排水结构，包括槽体，所述槽体内的底板上设有排液口，所述排液口上设有漩涡结构。本实用新型通过在槽体排水口加工时，在排水口周围加工一圈顺时针或逆时针旋转的漩涡形凹槽，在排液的过程中，受漩涡叶片之间的凹槽导流的影响，排水口的液体会很容易形成漩涡，漩涡形成后管道内的空气从漩涡的中心往上排出，同时管道内形成一定的负压，可以加快排液的速度。
