The water discharge flange 20 is provided below the water tank 10 and connected to the water discharge port 11, and the water discharge flange 20 has an inner cavity 20a therein. The overflow pipe 30 is disposed in the water tank 10, the overflow pipe 30 has a water inlet 31 at an upper end thereof and a water outlet 32 at a lower end thereof, the overflow pipe 30 has a lower end inserted into the inner cavity 20a through the water outlet 11, and a water passage 20b is defined between an outer wall of the overflow pipe 30 and an inner wall of the water outlet flange 20.

Illustratively, the drain opening 11 is formed in the bottom wall of the tank 10, and the drain flange 20 is formed below the tank 10 and connected to the drain opening 11. The upper end of the inner cavity 20a forms a water inlet end and is communicated with the water outlet 11, and the lower end of the inner cavity 20a forms a water outlet end. The overflow pipe 30 may be angled from the horizontal in the axial direction, for example, the overflow pipe 30 may be angled at a right angle with respect to the horizontal, i.e., the overflow pipe 30 may be arranged in the vertical direction in the axial direction, and the upper end of the overflow pipe 30 forms the water inlet 31 and the lower end forms the water outlet 32. Further, the upper end of the overflow pipe 30 is located above the bottom wall of the water tank 10, the lower end of the overflow pipe 30 passes through the water outlet 11 and is inserted into the inner cavity 20a, wherein the overflow pipe 30 is inserted between the outer wall of the inner part of the inner cavity 20a and the inner wall of the inner cavity 20a to form a water passing channel 20b, the upper end of the water passing channel 20b is communicated with the inside of the water tank 10 through the water inlet end of the inner cavity 20a and the water outlet 11, and the lower end of the water passing channel 20b is communicated with the outside through the water outlet end of the inner cavity 20 a.
