Closestool

Abstract

A closestool comprises a toilet, wherein the toilet is provided with a water tank connecting part, a pool, a jet channel and a siphonage pipeline; a drain outlet is arranged at the bottom of the pool; the inlet end of the siphonage pipeline is communicated with the drain outlet; the outlet end of the siphonage pipeline is communicated with the outside; a water inlet hole is formed at the inlet end of the jet channel; a jet hole is formed at the outlet end of the jet channel; the jet hole is less than the sectional area of the jet channel; the water inlet hole is positioned on the left or right of the water tank connecting part; the jet hole is communicated with the drain outlet; and the jet channel is smooth arc transition from the water inlet hole to the jet hole. According to improvement on the structure and the position of the jet channel, water pressure loss is low and large water flow jet pressure is achieved, so the diameter of the siphonage pipeline is larger than that of the common toilet, the siphonage pipeline has strong dirt passing capacity and is difficult to block, the time and the water quantity required for forming siphonage are less than those of the common toilet, and the toilet saves more water compared with the common toilet.

Description

technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a toilet. Background technique [0002] The toilet is an indispensable article in people's life. People's requirements for the toilet are water saving and cleanliness, which means that the toilet technology will always work towards the direction of using less water to flush cleaner. The toilet of the prior art usually includes a water tank, a spray channel connecting the water tank and the pool, and a drainage channel for discharging dirt. The water discharged from the jet channel of the siphon toilet directly enters the drainage channel, and a negative pressure is formed at the junction of the drainage channel and the pool, and the dirt enters the drainage channel through the siphon and is discharged. However, the design of the spray channel in the prior art does not make full use of the gravity of the water flow. Due to the unreasonable design of the spray channel, the w...

Problems solved by technology

However, the design of the injection channel in the prior art does not make full use of the gravity of the water flow. Due to the unreasonable design of the injection channel, the water flow is bent many times in the flow of the injection channel, and the water pressure is greatly reduced, resulting in insufficient impact force.

Therefore, the drainage channel cannot use a larger diameter. If the diameter is too large, it will easily lead to the problem that the water pressure is not enough to push the air in the drainage channel to form a negative pressure.
