The present invention relates to a drainage apparatus for a sink, in which it is possible to drain wash water rapidly without having residue substances such as foreign substances and the like caught thereon, and prevent leakage of malodor in advance, thereby achieving excellent cleanliness, facilitating an operation and maintenance of the drainage apparatus due to its simple configuration and structure. Thus, according to the drainage apparatus for a sink of the invention, residue substances, foreign substances and the like are not caught on the drainage apparatus, the female screw-shaped grooves induce vortex of wash water, thereby rapidly draining the wash water, and the float ball made of positive buoyancy material is insertingly mounted inside of the tubular drainage body so as to ascend or descend by means of the wash water, thereby preventing leakage of malodor in advance, achieving excellent cleanliness, and facilitating an assembling operation and maintenance/repair of the drainage apparatus due to its simple configuration and structure.

1. A drainage apparatus for a sink, comprising: a main body having a drainage hole formed thereon, the main body including an annular retaining step formed on an inner peripheral wall defining the drainage hole, and a coupling member formed unitarily with the main body and extending downwardly from the annular retaining step and having a male screw portion on an outer surface of the coupling member;a tubular drainage body having a female screw portion screw-coupled to the male screw portion of the coupling member, and a transportation hose for connecting to a lower portion of the tubular drainage body;a filtering mesh for filtering water from residue substances in the sink; anda cover for covering the drainage hole with the cover seated on the annular retaining step,wherein the filtering mesh includes a plurality of pillars extending downwardly from a lower annular edge thereof so as to define a space portion therein for receiving a float ball therein, and the plurality of pillars are seated on an inner lower portion of the tubular drainage body. 2. The drainage apparatus according to claim 1, wherein the tubular drainage body is shaped to be stepwisely narrower in diameter as it goes from the top to the bottom and has a plurality of grooves formed on the inner peripheral wall surface of the lower portion thereof so as to induce vortex of water passing therethrough while dropping down. 3. The drainage apparatus according to claim 1, wherein the float ball is made of buoyancy material and configured to shut off the lower end portion of the tubular drainage body and also to allow the water to be discharged as the float ball ascends by the buoyancy created when the water drops or fills into the tubular drainage body. 4. The drainage apparatus according to claim 2, wherein the float ball is made of buoyancy material and configured to shut off the lower end portion of the tubular drainage body and also to allow the water to be discharged as the float ball ascends by the buoyancy created when the water drops or fills into the tubular drainage body. 5. The drainage apparatus according to claim 3, wherein the float ball includes a cleaning brush on the outer peripheral surface thereof so as to clean the inner peripheral wall of the tubular drainage body when the float ball ascends and descends in the space portion of the filtering mesh. 6. A drainage apparatus for a sink, comprising: a main body having a drainage hole formed thereon, and a coupling member extending downwardly from the drainage hole portion and having a male screw portion on an outer surface of the coupling member;a tubular drainage body having a female screw portion screw-coupled to the male screw portion of the coupling member, and a transportation hose for connecting to a lower portion of the tubular drainage body;a filtering mesh for filtering water from residue substances in the sink; anda float ball made of buoyancy material and received in the tubular drainage body, the float ball configured to shut off the lower end portion of the tubular drainage body and also to allow the water to be discharged as the float ball ascends by the buoyancy created when the water drops or fills into the tubular drainage body, the float ball including a cleaning brush on the outer peripheral surface thereof so as to clean the inner peripheral wall of the tubular drainage body when the float ball ascends and descends in the space portion of the filtering mesh. 7. The drainage apparatus according to claim 6, wherein the main body further comprises an annular retaining step formed on an inner peripheral wall defining the drainage hole, and a cover for covering the drainage hole by seating on the annular retaining step. 8. The drainage apparatus according to claim 6, wherein the filtering mesh includes a plurality of pillars extending downwardly from the lower annular edge thereof so as to define a space portion therein, and the plurality of pillars are seated on an inner lower portion of the tubular drainage body.
