PURPOSE:To prevent overflow out of an overflow port even when liquid level in a receiving tank is high by arranging a partition plate, with a gap interposed, around a guide cylinder arranged around a nozzle with a space interposed. CONSTITUTION:Facing to a water inlet 14, a cylindrical nozzle 15 is arranged. A guide cylinder 17 is arranged around the nozzle with a space interposed. The guide cylinder is so arranged that the upper rim of the guide cylinder is above the upper rim of an overflow port 13 and the lower rim of the guide cylinder is below the lower rim of the overflow port 13. Further, a partition plate 19 is arranged above the upper rim of the overflow port 13 and around the guide cylinder 17 with a gap interposed so that inside of a hopper 10 is divided into upper and lower sections. With this constitution, smooth liquid flow into a receiving tank is possible even when liquid level in the receiving tank becomes high, without causing flow obstruction due to air trap in a communication pipe 12. |
