Toilet

Abstract

A toilet, including: a bowl member having a contraction portion, which is narrowed from a top to a bottom thereof. There is a water passing rim provided at the top rim of the contraction portion. A receiving portion is provided below the contraction portion. The receiving portion connects with a discharging pipe. A water tank places at one side of the bowl member. The water tank has an exit. A divided pipe places under the tank and connects with the exit. The divided pipe has a first exit and a second exit. A down tunnel connects with the second exit of the divided pipe in one end and with the receiving portion in the other end. The end of the down tunnel that connects with the receiving portion points to the discharging pipe and forms a jet water delivery port. The down tunnel has a downward section. A water rim duct connects with the first exit of the divided pipe in one end and the water passing rim in the other end. An air ductule, the down end of the air ductule connects with the downward section of the down tunnel and the up end of the air ductule connects with the water passing rim.
