PURPOSE: A drainage unit of a sink bowl is provided to prevent backward flow of bad smell and discharge cleaning water without using a lid within a sink bowl, since a valve body is installed at the lower end of the casing. CONSTITUTION: A drainage unit of a sink bowl comprises a stainless casing, a valve(21), and a branched pipe(22). The stainless casing mounts a connection pipe at the bottom center of the casing. The valve body is connected to the connection pipe. The valve body opens and closes pipes by the rotation of a lever(20). The branched pipe is fixed and coupled with the valve body. The branched pipe has a water inlet and a water outlet in the vertical direction of the body. The branched pipe is projected in one direction of the body. An overflow pipe(26) connects to a drain hole for water level control which is formed at the upper end of the side of a sink bowl(12). |
