Drain socket and flush toilet

Abstract

The present invention provides a flush toilet or a drain pedestal that prevents clogging of pipes by aligning the direction of dirt passing through a drain trap without hindering the discharge capacity of drain by siphon action. The drain socket of the present invention is a drain socket that connects the outlet (7) of the elbow drainage channel of the flush toilet body (5) and the drain pipe (2) arranged outside the flush toilet body, and is characterized in that: It has: a drainage seat body (3) connected to the inlet of the elbow drainage road and the outlet connected to the drainage pipe; a siphon induction part arranged on the inner wall of the drainage seat body to induce the siphon effect (11); and a rectifying plate (4) extending from the inner wall surface toward the inner side of the flow path at the upstream of the siphon induction part of the drain socket body.

Description

technical field [0001] The present invention relates to an improvement of a drainage seat connected and arranged between the outlet of the elbow drainage path of the flush toilet to the end of the elbow drainage path of the flush toilet body and the drain pipe outside the toilet. Background technique [0002] Conventionally, as a method of improving the waste discharge performance of flush toilets, a siphon effect has been utilized. As this type of flush toilet, in order to induce siphon action, a side flow hole is formed on the outlet, and a necked drain seat is provided on the upstream side of the side flow hole (for example, refer to JP-A-8-260551). (pp. 2-4, figure 1 )). In this drain socket, a water film is formed by making the wash water turbulent through the constricted portion on the upstream side and the two stages of the side flow hole of the outflow port, so that the siphon effect occurs early. [0003] Moreover, this kind of drainage seat is made of the turbul...

AI Technical Summary

Problems solved by technology

[0005] However, in the above-mentioned drain socket, the upper floor forming the constriction and the horizontal step portion or the side flow hole may become obstacles, and the dirt collides with it to block the flow path, and other dirt may not easily pass through.

Moreover, since the above-mentioned step or the side flow hole is horizontal, dirt remains on the step and accumulates after draining, causing clogging of the piping.

[0006] Moreover, in the drain socket described in the above-mentioned Japanese Patent Laid-Open No. 8-260551, since the water film is formed by the constricted portion on the upstream side and the two stages of the side flow hole of the outflow port, there is early generation of siphon and large siphon. However, it is insufficient in the continuation of the siphon, and the suction and discharge of floating dirt at the end of the siphon are weak.

In addition, there are cases where the constricted part and the side flow holes become obstacles, and especially large-scale dirt is difficult to pass through.

On the other hand, in the drain socket in which the concave-convex portion is formed in the direction parallel to the ground described in the above-mentioned Japanese Patent Laid-Open No. 2001-279796, since the inner diameter of the convex portion is smaller than that of the outlet and the number of the outlet is large, there is a possibility that this will become an obstacle. , especially when large-scale dirt is not easy to pass through

In addition, in the drain socket provided with a storage chamber different from the flow path described in the above-mentioned JP-A-2001-279796, the overall structure of the drain socket becomes complicated, and the productivity is not good.

[0007] Moreover, in the drain socket described in the above-mentioned Japanese Patent Laid-Open No. 8-326136, it can correspond to the case of a flush toilet in which the outlet of the flush toilet and the drain pipe are not integrated, and can also induce a siphon effect, but in In this type of drainage socket, dirt tends to adhere to the horizontal weir, and large-scale dirt cannot be washed away smoothly.
