SIPHON OFF TOILET TRAP FORMED AIR DISCHARGING GROOVE

摘要

PURPOSE: A toilet bowl trap with an air discharging groove for the blockage of siphon is provided to block siphonage at the desired point in an early stage by the ventilation groove in a trap, thereby providing excellent saving water effect. CONSTITUTION: A toilet bowl trap with an air discharging groove for the blockage of siphon has at least one air discharging section (A), which has the cross-sectional area of a trap pipe conduit temporarily increased, between the top of a main trap and a trap discharging port. The air discharging section discharges air ascending from a bottom drain toward the top of the main trap. At least one air discharging groove (B), which has the one portion of the inner surface of the trap pipe conduit expanding toward the outer circumference in a groove form, is formed in the air discharging section.
