Flushing structure of flushing-down type closestool

Abstract

The flushing structure comprises a urinal, a blow-off pipe and a seat ring, and the urinal comprises a front wall surface, a side wall surface and a rear wall surface; the seat ring is arranged at the top of the urinal, a flushing structure is arranged at the lower part of the seat ring, the flushing structure comprises a water distribution hole and a flushing hole which are formed above the rear wall surface, and a water guide edge which extends from the flushing hole to the front end of the urinal, and the water guide edge is positioned at the upper edges of the side wall surface and the front wall surface; the blow-off pipe comprises an inlet section and a connecting section, the inlet section extends towards the rear portion of the urinal from top to bottom, the bottom of the inlet section is communicated with the connecting section, the top of the inlet section is communicated with the bottom of the urinal, and the inner wall of the inlet section and the front wall face are in smooth transition. A protruding part protruding towards the inner side of the urinal or the inlet section is formed by the front wall face and the rear wall face. The flushing cleanliness and efficiency are improved, and water splashing in the flushing process is avoided.

Description

technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a flushing structure of a flush toilet. Background technique [0002] The flush toilet is a kind of toilet that directly discharges the dirt by the momentum of flushing water. It is different from the siphon toilet in that only positive pressure is formed in the process of flushing and sewage discharge, and there is no negative pressure. The acceleration of gravity can wash away the dirt. The flushing pipeline of the flush toilet is simple, the path is short and thick, and the flushing process is short. [0003] Common flush toilets include pure cloth water hole type and surround type. The pure cloth water hole type flush toilet is evenly provided with a circle of small holes on the inclined concave surface of the inner wall of the seat ring, and the water in the water channel of the seat ring flows out from the small holes for flushing. The advantage of the pure cloth w...

AI Technical Summary

Problems solved by technology

[0006] (1) There is a corner between the front wall of the urinal and the upper end of the sewage inlet. The water flow at the front falls at the corner and collides with the bottom of the urinal and disperses, and then gathers and rushes into the pipeline. The flushing force is dispersed and the flushing performance is reduced;

[0007] (2) The direction of water flow in the auxiliary flushing hole is affected by the direction and slope of the hole. Since the rear wall of the urinal is relatively steep, the sewage inlet is almost vertical, and the auxiliary flushing water is easy to rush directly into the rear end of the sewage inlet to cause splashing;

[0008] (3) When flushing the dirt, the auxiliary flushing water collides with the main flushing water flow when it falls directly to the sewage inlet, forming recoil resistance, and the sewage cannot all enter the sewage pipe due to its obstruction, reducing the flushing performance
