Abstract
PURPOSE: To permit wall drainage by partially reducing a trap drain path diameter between a weir portion and a water pool portion, suspending a partition wall leaving an air passage space to the stored water surface at an upper wall of a water pool portion and providing a notch in the partition wall. CONSTITUTION: In a space between a weir portion 4 and a water pool portion 5, the diameter of a 'b' portion of a trap drain path 2 is gradually reduced toward a bottom portion, and thus the drain path diameter is partially reduced. Also at the upper wall of the water pool portion 5, a partition wall 7 extending downward is formed so as to leave some air vent space 6 between the lower end and the stored water surface of the water pool portion 5. Then, a notch 8 of an adequate width is provided in the partition wall 7 from its lower end to a middle portion in the height direction. Therefore, an air vent space 6 is partitioned to a wall shape by a flux of water dropping from the weir portion 4 during washing and the rise in water level at the water pool portion 5, a negative pressure occurs inside the trap and thus the siphon action tends to occur easily.
