PURPOSE: A toilet bowl is provided to prevent contaminated water filled with easing nature from flowing reversely to a water tub by closing a drain hole of an overflow pipe when a toilet bowl body is closed by easing nature. CONSTITUTION: A toilet bowl comprises an overflow portion(100), a backflow cutoff portion(200), and a washing water cutoff portion(300). The backflow cutoff portion is installed on the overflow portion. The backflow cutoff portion prevents the contaminated water in the toilet bowl body from flowing backward to the inside of the water tub. The washing water cutoff portion rises according to the water level flowing reversely to the overflow portion of the contaminated water and blocks the washing water supplied to a water tub. |
