Abstract

PURPOSE: To early generate siphon effect and suppress wasteful flushing water consumption by providing a diaphragm on the upstream side of the orifice of a drainage socket, and colliding a part of flushing water to the diaphragm and the orifice, respectively, to scatter the flushing water. CONSTITUTION: Another diaphragm 13 is arranged on the upstream side from an orifice 11, and it is formed by utilizing a stepped part 10 which is the part for branching an inner cylinder 4 from an outer cylinder 5, and the stepped part 10 is formed so as to be protruded inward. The lower side of the diaphragm 13 is extended in diameter to the lower part in a tapered form, and continued to the orifice 11. The flushing water carried from a toilet bowl side is collided with the stepped part 10, scattered inward, and laid in turbulent state, which facilitates the formation of a water film. The capacity of the area between the stepped part 10 and the orifice 11 is minimized. Therefore, the water quantity to provide a full-water state necessary for generating a siphon effect can be minimized, and the siphon effect can be generated early for this portion.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage socket for connecting a defecation pipe connected to sewage or the like and an outlet of a defecation passage of a toilet bowl.

[0002]

2. Description of the Related Art A conventional structure for connecting a defecation pipe, which is connected to sewage or the like, and an outlet of a defecation passage of a toilet bowl, is as shown in a vertical sectional view of FIG. As shown in the figure, a defecation pipe 2 which is in communication with a sewer pipe or the like when a building body is constructed is vertically embedded in a floor 1 of a toilet room.
And, on the inlet side opening to the toilet room of the defecation pipe 2,
The inner cylinder 4 of the drain socket 3 is fitted inside. The lower half 5a of the outer cylinder 5 of the drain socket 3 is placed on the floor 1, and the upper half 5a
b is attached to the outlet 9 of the defecation passage 8 of the toilet 7 via the packing 6.

Further, the inner cylinder 4 of the drain socket 3 is formed only in the lower half part, and between the inner cylinder 4 and the outer cylinder 5,
Step 10 for attaching the drain socket 3 to the defecation passage 8
Are formed. Further, on the inner bottom surface side of the inner cylinder 4, an orifice 11 for generating a siphon action is formed.

The orifice 11 interrupts a part of the flow of the toilet flush water flowing down through the defecation passage 8 to cause a turbulent flow in the part to form a water film. It serves to fill the defecation passage 8 with water.
After that, the flush water flows down so that the flush water is dragged toward the defecation pipe 2 side, and a so-called siphon action is generated. This siphon action improves the carrying output of filth and allows the filth to be poured all at once.

[0005]

As described above, in the conventional toilet bowl, the siphon action is generated to carry out the waste and wash the toilet bowl with a strong carry output. However, in the conventional drain socket 3, only the orifice 11 is formed as a means for generating the siphon action, and a large amount of washing water flows to the defecation pipe 2 side until the siphon action occurs. However, there is a drawback that the amount of wasted washing water increases.

[0006]

SUMMARY OF THE INVENTION The present invention has been improved and eliminated in view of the above-mentioned problems of the related art. By generating a siphon action at an early stage, the amount of wasted washing water is suppressed and water saving is realized. The purpose is to provide a drain socket designed to do so.

In order to solve the above-mentioned problems, the means of claim 1 adopted by the present invention provides a defecation pipe communicating with sewage and the like and an outlet of a defecation passage of a toilet bowl via a drain socket. A drainage socket for connecting a toilet bowl and a defecation pipe, characterized in that an orifice is formed on the outlet side of the drainage socket, and a throttle is provided on the upstream side of the orifice.

According to the second aspect of the present invention,
In the one that connects the defecation pipe that is connected to sewage and the like and the outlet of the defecation passage of the toilet via the drain socket,
Toilet bowl and defecation characterized in that an orifice is formed on the outlet side of the drainage socket, and the flow paths on the inlet side and the outlet side of the drainage socket are arranged so as to partially overlap each other in a plan view. It is a drain socket for pipe connection.

Further, the means of claim 3 adopted by the present invention is characterized in that the cross-sectional profile of the flow passages on the inlet side and the outlet side of the drain socket is circular and the other is oval. The drainage socket for connecting a toilet bowl and a defecation pipe according to claim 2.

Furthermore, the means of claim 4 adopted by the present invention is characterized in that the center positions of the flow passages on the inlet side and the outlet side of the drain socket are eccentric. It is a drain socket for connecting a toilet bowl and a defecation pipe.

[0011]

In the means of the first aspect of the present invention, the throttle 13 is provided on the upstream side of the orifice 11 of the drain socket 12. By providing the throttle 13, a part of the wash water flowing down the defecation passage 8 of the toilet 7 randomly hits the throttle 13 and scatters to be in a turbulent state. Subsequently, the washing water randomly hits and scatters also at the orifice 11 on the downstream side, forming a turbulent flow and forming a water film. In this way, the turbulent flow state of the wash water is created in the two stages of the throttle 13 and the orifice 11 to form a water film, and the flow passage volume between the throttle 13 and the orifice 11 is made small, so that early It is possible to obtain a full-filled state, and it is possible to significantly reduce the time required for the occurrence of the siphon action as compared with the conventional case.

According to the means of claim 2 of the present invention,
The flow passages on the inflow port 14 side and the outflow port 15 side of the drainage socket 12 partially overlap each other in a plan view. As the overlapping means, the cross-sectional shape may be changed as shown in claim 3, or the center positions of the flow paths may be decentered from each other as shown in claim 4. As a result, the area of the portion where the wash water directly flows down to the defecation pipe 2 can be reduced, and a turbulent flow state can be generated in the wash water. Therefore, a water film is formed on the drain socket 12, a full state is obtained, and the siphon action occurs at an early stage. In other words, it is possible to save water by suppressing the amount of wasted wash water that would otherwise cause a siphon action.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 is a vertical cross-sectional view showing the entire drainage socket 12 according to the first embodiment of the present invention. As shown in the figure, another throttle 13 is formed on the upstream side of the orifice 11 of the drain socket 12. The diaphragm 13 of this embodiment is formed by utilizing a step portion 10 which is a portion where the inner cylinder 4 branches from the outer cylinder 5, and the step portion 10 is formed so as to further project inward. . The lower side of the throttle 13 is formed in a tapered shape so that the diameter thereof increases as it goes downward, and is continuous with the orifice 11.

By thus forming the throttle 13 on the upstream side of the orifice 11, the cleaning water flowing from the toilet bowl side first collides with the step portion 10 and is scattered inward.
Generates a turbulent state. Then, also in the orifice 11, it collides with the bottom wall surface and scatters inward to generate a turbulent flow. Therefore, in the flow path in the region between the step portion 10 and the orifice 11, a very turbulent state is intensely performed, and the water film is easily formed.

By forming the throttle 13, it is possible to reduce the volume of the region between the step 10 and the orifice 11. Therefore, the amount of water required to obtain a full-filled state required to generate the siphon action is small, and the siphon action can be generated earlier correspondingly. That is, the water film forming action by the two turbulent states of the step portion 10 and the orifice 11 of the throttle 13 and the throttle 1
Due to the synergistic effect of reducing the flow path volume between the nozzle 3 and the orifice 11, the siphon action can be generated in an extremely short time after the start of toilet cleaning, and the water saving effect is excellent. The water saving effect by the siphon action is the same as the conventional case.

FIG. 2 is a vertical sectional view showing the entire drainage socket 16 according to the second embodiment of the present invention. In the second embodiment, the lower side of the diaphragm 13 of the first embodiment has a rectangular cross section and is connected to the orifice 11. Other configurations and operational effects are the same as in the case of the first embodiment described above.

FIG. 3 is a vertical sectional view showing the entire drainage socket 17 according to the third embodiment of the present invention. In this embodiment, the first diaphragm 13a and the second diaphragm 13b are formed by forming the concave portion 18 in the middle of the diaphragm 13, and the flow path region between the step portion 10 and the orifice 11 is formed. A three-stage water film is formed. Other configurations and basic effects are the same as in the case of the first embodiment described above.

Next, a fourth embodiment of the present invention will be described with reference to FIGS. In this embodiment, the flow passages on the inlet 14 side and the outlet 15 side of the drain socket are made to partially overlap each other in a plan view.
4 and FIG. 5 (a) show the inflow port 14 side and the outflow port 15 side.
Each of the flow paths on the side has a circular shape, and its center position is eccentric.

In FIG. 5B, the center positions of the flow paths on the inlet 14 side and the outlet 15 side are the same, one side of the flow path is circular and the other side is elliptical. It was done. Further, FIG. 5C shows that the inlet 14 side and the outlet 15
The center positions of the side flow paths are the same, both flow paths are elliptical, and the major axes of the ellipses are arranged so as to differ by 90 degrees.

In this way, when the flow paths on the inlet 14 side and the outlet 15 side are made to partially overlap each other in a plan view, the inlet 14 and the outlet 15 side are directly connected. The amount of water flowing to the side of the defecation pipe 2 decreases. Therefore, the remaining cleaning water other than the cleaning water that directly passes through the inflow port 14 and the outflow port 15 collides with the respective wall surfaces at the inflow port 14 and the outflow port 15 and scatters inward to generate a turbulent flow. It is generated to form a water film.

As a result, the time from the start of toilet cleaning to the occurrence of the siphon action is short, and the siphon action can be generated early. In addition, the amount of wash water flowing directly through the inflow port 14 and the outflow port 15 can be reduced until the siphon action occurs, and significant water saving can be achieved by the synergistic effect of these. is there.

By the way, the present invention is not limited to the above-mentioned embodiment, and for example, the inlet 14 side and the outlet 1 are provided.
The cross-sectional shape of the flow path with the 5 side may be a quadrangle or another polygonal shape. Further, a combination of these polygonal channels and the above-mentioned elliptical or circular channels may be used. Further, the throttle 13 formed on the upstream side of the orifice 11 may be of a multi-stage type having two or more stages.

[0023]

As described above, according to the means of claim 1 of the present invention, since the throttle is provided on the upstream side of the orifice of the drainage socket, a part of the toilet flush water and the orifice are respectively provided. It is possible to form a water film by causing the particles to collide with each other and scatter to form a turbulent flow state. Moreover, by providing the throttle, it is possible to reduce the flow path volume between the throttle and the orifice, and by the synergistic effect of these, it is possible to obtain a full-filled state at an early stage and reduce the time required for the occurrence of the siphon action. Compared with the conventional case, it can be shortened significantly and water can be saved.

According to the means of claim 2 of the present invention,
Since the flow paths on the inlet side and the outlet side of the drainage socket are made to partially overlap each other in a plan view, it is possible to reduce the area of the portion where the flush water directly flows down to the defecation pipe. It is possible to cause a turbulent flow state in the remaining wash water. Therefore, a water film is formed on the drain socket, a full state is obtained, and the siphon action occurs at an early stage. In other words, it is possible to save water by suppressing the amount of wasted wash water that would otherwise cause a siphon action.

In addition to that, the drain socket of the present invention is
A diaphragm and an orifice are provided in one member, and it is possible to obtain a water-saving effect by forming a water film and reducing the volume of the flow channel. Compared with the case where such a member is formed by another member. The degree of eccentricity due to variations in construction does not greatly deviate. That is, the drain socket of the present invention, when the throttle and the orifice are provided in one member,
