Description

Drain casing

The present invention relates to a drainage sleeve connecting the outlet of the toilet body and the drainage opening on the floor.

In the conventional Western-style toilet device, when the toilet body is installed in such a way that the outlet of the toilet body (the trap) and the drain opening on the floor are spaced apart on the plane, the distance between the toilet body is taken into consideration and used Drain sleeve (for example, refer to Patent Document 1).

The flange portion provided to protrude to the periphery of the bent portion of the drainage port connecting portion of the drainage sleeve is approximately circular in plan. For example, the drain sleeve of Patent Document 1 is the same. In the flange portion, the side flanges located on both sides of the bent portion and the front flange located on the front side of the bent portion have the same protruding size from the bent portion. In addition, a screw fixing hole is provided on the side flange, and a screw fixing hole is not provided on the front side of the bent portion.

In this way, even though the screw fixing hole is not provided, the front flange of the flange part is protruded like the side flange in order to reliably cover the floor flange with the insertion part directly installed in the drain port and separated from the drain sleeve body The reason. In addition, considering such a double structure, the flange may be provided with a screw fixing hole before it protrudes significantly. In addition, if such a floor flange is provided, although the positional deviation of the discharge port on the side of the bent portion and the drain port on the floor surface can be absorbed, it is necessary to make the front flange protrude significantly.

[Problem to be solved by invention]

However, when using the above-mentioned drain sleeve, it is of course necessary to hide the connection part of the drain sleeve of the drain sleeve and the connection part of the drain port on the peripheral wall of the device body. Therefore, the flange must be covered with the peripheral wall before the toilet body is provided as the flange. In other words, if the front flange protrudes to a large extent, the toilet body must be installed such that the front end of the peripheral wall is arranged in front of the front end of the front flange.

In short, the greater the protruding degree of the front flange, the greater the distance between the toilet body and the back wall of the toilet, and the stricter conditions and restrictions on the location of the toilet body, even the modification cannot cope with it.

The present invention is proposed in consideration of this situation, and its purpose is to provide a drainage sleeve that can relax the conditions and restrictions of the installation position of the toilet body. [Means to Solve the Problem]

In order to achieve the above object, the drainage sleeve of the present invention is a drainage sleeve that connects the outlet of the toilet body to the drainage outlet opened on the floor, and includes a toilet connector connected to the outlet and a toilet connected to the outlet. The drain connection part, the horizontal piping part connecting the toilet connection part and the drain connection part; the drain connection part has a bent part arranged to extend from the end of the horizontal piping part to communicate the bent part inside The method of the part extends into a cylindrical shape and is installed in the drainage port insertion portion of the drainage port, and the boundary between the bent portion and the drainage port insertion portion on the outer peripheral surface side protrudes to the outside and is provided on the floor surface. The flange portion has at least a side flange located on both sides of the bent portion in the direction perpendicular to the direction in which the horizontal piping portion extends and has a screw fixing hole, and a front flange located on the opposite side of the horizontal piping portion ; The protrusion degree of the front flange is less than the protrusion degree of the side flange. [Effects of Invention]

Since the drainage sleeve of the present invention has the above structure, the conditions and restrictions on the installation position of the toilet body can be alleviated.

[Form to implement the invention]

Hereinafter, the embodiments of the present invention will be described with reference to the attached drawings. First, the outline basic structure of the drainage sleeve 20 will be described. In addition, the following description is based on the toilet device 1 with the drain sleeve 20 installed, and the front and back, up and down directions are specified.

As shown in FIGS. 1 and 2, the drain sleeve 20 connects the outlet 13 of the toilet body 10 and the drain 7 opened on the floor surface 5. It includes a toilet connecting portion 21 connected to the outlet 13, a drain connecting portion 23 connected to the drain port 7, a horizontal piping portion 22 connecting the toilet connecting portion 21 and the drain connecting portion 23.

The drainage port connection portion 23 has a structure including a bent portion 24, a drainage port insertion portion 25 and a flange portion 26. The curved portion 24 is arranged to extend from the end of the horizontal piping portion 22, and the drainage port insertion portion 25 is inserted into the portion installed in the drainage port 7 and extends into a cylindrical shape so as to communicate with the curved portion 24 inside. The outer shape of the drainage port insertion portion 25 is a tapered shape that is narrowed downward by changing the thickness of the tube. Also, as shown in Figure 1 (b) and (c), the flange portion 26 is provided on the floor surface 5, and the boundary between the curved portion 24 and the drain insertion portion 25 on the outer peripheral surface side protrudes to the outside .

The flange portion 26 has at least side flanges 26a located on both sides of the bending portion 24 in a direction perpendicular to the direction in which the horizontal pipe portion 22 extends, and having screw fixing holes 26aa, and a front projection located on the opposite side of the horizontal pipe portion 22缘26b. The protrusion degree of the front flange 26b is smaller than the protrusion degree of the side flange 26a.

Furthermore, as shown in FIG. 2, the toilet device 1 to which the drain sleeve 20 is installed includes the toilet body 10 described above and a peripheral wall 15 surrounding the toilet body 10. The toilet body 10 has a bedpan 11 whose bottom is narrowed into a mortar shape, a trap 12 connected to the outlet 11a on the bottom side of the bedpan 11, a toilet seat (not shown in the figure), and a toilet cover (not shown in the figure) .

This trap 12 is a mechanical action type, as shown in Figure 2 with a two-dot chain arrow, it has a cylindrical bellows structure and can be switched between the sealing position (up position) and the drainage position (down position) . The trap 12 is arranged in the trap box 14, and the drain water discharged from the outlet 12a of the trap 12 is discharged from the lower end opening of the trap box 14 (outlet 13 of the toilet body 10). The outlet 13 has a cylindrical shape and is connected to the drainage inlet 21a of the drainage sleeve 20.

The peripheral wall 15 of the toilet body 10 is arranged around the toilet bowl 11 and the trap 12 so as to hide them.

Moreover, this peripheral wall 15 is also arranged so as to also surround the above-mentioned drain port 7. The drainage port 7 is in front of the outflow port 13 of the toilet body 10 and below the front portion of the bowl 11. The drain port 7 is connected to the drain port insertion portion 25 of the drain port connection portion 23 of the drain sleeve 20. Therefore, the drainage sleeve 20 arranged to connect the outflow port 13 and the drainage port 7 of the toilet body 10 is also hidden by this peripheral wall 15.

The toilet device 1 that can be equipped with the drainage sleeve 20 is not limited to the toilet device with the machine-operated trap 12 shown in FIG. 2, and can also be applied to the toilet device with a fixed trap. If it is a toilet device in which at least the drain port 7 of the floor surface 5 and the outflow port 13 of the toilet body 10 are spaced apart in the front-rear direction, such a drain sleeve 20 can be used.

Next, the detailed structure of the drainage sleeve 20 and the relationship between the drainage sleeve 20 and the toilet device 1 will be described in detail based on FIGS. 1 to 3.

As described above, the drain sleeve 20 includes a toilet connecting portion 21, a horizontal pipe portion 22, and a drain port connecting portion 23. The drain sleeve 20 of the present embodiment is composed of three components that can be separated from the divisions of these parts. Specifically, the drain sleeve 20 is composed of three members: a first constituent material 31, a second constituent material 32, and an adjustment coupling 33.

As shown in FIG. 1(a), the first constituent material 31 is a member that has a toilet connection part 21 of a drainage inlet 21a and a cylindrical part 31a of a part of the horizontal pipe part 22 on the toilet connection part 21 side. In addition, an installation stand 31c for stably installing the first component 31 on the floor surface 5 is integrally formed on the lower side of the drain inlet 21a of the first component 31.

The second constituent material 32 corresponds to the member connected to the drain port connection portion 23 of the horizontal piping portion 22 (refer to Figure 1(b), (c)). Therefore, it has a body tube with a larger diameter than the drain port connection portion 23 on the toilet side The toilet side opening 32a of the part. The lower part of the outer surface of the toilet-side opening 32a is formed thick to adjust the height.

In addition, the adjustment coupling 33 is used to form the cylindrical portion 31a of the first constituent material 31 and the adjustment coupling 33 by coupling the adjustment coupling 33 itself between the first constituent material 31 and the second constituent material 32 A cylindrical member of the horizontal piping section 22. In addition, it is desirable to provide a drain slope for draining water on the inner bottom surface of the horizontal pipe portion 22.

This adjustment coupling 33 has a large diameter part 33a and a small diameter part 33b, and the large diameter part 33a is connected to the drainage side opening part 31b of the cylindrical part 31a of the 1st component 31 in an external fitting manner. In addition, the small-diameter portion 33b is connected to the toilet-side opening 32a of the second constituent material 32 so as to be embedded.

Since the drainage sleeve 20 is a member that connects the drainage position of the trap 12 (the position of the drainage inlet 21a of the toilet connecting portion 21) and the drainage port 7 in the front-rear direction, the total length of the drainage sleeve 20 needs to be The distance between the posture position and the position of the drain 7 is approximately the same. To form such a length, the small diameter portion 33b may be cut to adjust the length. In addition, the drainage sleeve 20 may also have a structure that does not use such an adjustment coupling 33. For example, it may be a structure that connects two members (for example, the first component 31 and the second component 32), or it may be a structure of four components (for example, the first component 31, the second component 32, and two adjustment The structure of the connecting device 33).

The drain port connection portion 23 corresponding to the second constituent material 32 includes a toilet-side opening portion 32 a, a curved portion 24, a drain port insertion portion 25, and a flange portion 26. From the toilet-side opening portion 32a to the drain port insertion portion 25 via the bending portion 24, the inside communicates.

By inserting and installing the drainage port insertion portion 25 in the drainage port 7, the drainage inlet portion 21a of the rear toilet connection portion 21 is arranged with the outflow port 13 of the toilet body 10 (the lower end of the trap box 14 is open The positions of the parts) are the same, and the drain sleeve 20 can be arranged in an appropriate position (refer to Figure 1 (a), Figure 2). In such a state where the drain sleeve 20 is properly installed, the back surface of the flange portion 26 abuts the ground plate surface 5.

As shown in FIG. 1(b), the flange portion 26 has two side flanges 26a located on both sides of the curved portion 24, that is, on both sides of the direction perpendicular to the longitudinal direction (drain flow direction) of the horizontal piping portion 22 , The front flange 26b located on the front side of the bent portion 24 is formed. In addition, the rear part of the flange part 26 corresponds to the lower part of the outer surface of the toilet side opening part 32a.

As shown in FIG. 1(b), the side flanges 26a protrude into a wing-like shape by bending or polygonal outer shape on both sides of the curved portion 24 in a plan view. The side flange 26a is respectively provided with two screw fixing holes 26aa arranged in a shape approximately along the outer edge and connected to the floor surface 5 by screws.

On the other hand, the front flange 26b protrudes into an approximately circular arc shape. Both ends of the arc are located inside the outer edge of the side flange 26a (the direction in which the two outer edges approach), and the arc is located at a position where the obtuse bent portion 26ba and the front edge 26ab of the side flange 26a are continuous .

All in all, the front flange 26b is shaped like a cut back from an imaginary bending line 27 (the two-dot chain line in FIG. 1(b)) backwards, and the imaginary bending line is the front end of the outer edge of the side flange 26a They are connected to each other in such a way that they are drawn forward without bending and are concentrically arcs with the front flange 26b. That is, the part of the side flange 26a provided with the two screw fixing holes 26aa is not formed in the front flange 26b so as to extend to the front, nor is the front flange 26b provided with holes for fixing with screws.

If the front flange 26b has such a shape, the dimension A from the center X of the water outlet 7 (refer to FIG. 1(b)) to the outer edge is much smaller than that from the center X of the water outlet 7 to the outer edge of the side flange 26a Dimension B (refer to Figure 1(b)). That is, the front end position C where the center line of the drainage sleeve 20 intersects with the arc-shaped outer edge of the front flange 26b in a plan view is located behind the front end position D before the center line crosses the imaginary bending line 27 (see FIG. 1(b) )).

3 is a schematic longitudinal cross-sectional view comparing the front end position C (this drain sleeve 20) and the end position D (the drain sleeve 200 corresponding to the front end position D). The peripheral wall 15 of the toilet device 1 needs to be arranged such that the lower end of the front end 15a is arranged in front of the front end position C and the front end position D. Therefore, when the distance between the front end position C and the front end position D and the front end 15a of the peripheral wall 15 is the same, the front end 15a at the front end position C is behind the front end 15a at the front end position D.

In summary, as shown in FIG. 1(b), if the front flange 26b protrudes forward less than the side flange 26a, the toilet device 1 can be made close to the back wall of the toilet (not shown). In other words, the flange portion 26 of the drain port connecting portion 23 of the drain sleeve 20 has the shape shown in Figure 1(b) and the toilet body 10 even if the conditions and restrictions of the installation position of the device 1 are reduced, the freedom of the installation position is increased. Degree related.

In addition, the back surface of the flange portion 26 (the surface on the side of the drainage port insertion portion 25) is substantially flat except for the screw fixing holes 26aa provided in the side flange 26a. Therefore, if the drain sleeve 20 is appropriately arranged, the flange portion 26 can be closely attached to the floor surface 5 approximately as a whole. Therefore, the stable installation of the drainage sleeve 20 can be realized.

In addition, since the drainage port insertion portion 25 is embedded in the drainage port 7 and the flange portion 26 is closely attached to the floor surface 5, the drainage port connection portion 23 of the drainage sleeve 20 can be prevented from deviating or tilting, and drainage can also be prevented. leakage.

In addition, since the drain port insertion portion 25 is integrally formed with the drain port connection portion 23 as a part of the drain sleeve 20, there is no need for a separate floor flange used in the installation of the conventional drain sleeve. Therefore, the drainage port insertion portion 25 needs to be formed so as to have no dimensional error to the drainage port 7. However, in this embodiment, the drain port insertion portion 25 is formed in a tapered shape that narrows downward, so even if there is a slight error, the drain port 7 can be accurately installed.

Since the drainage sleeve 20 has such a structure, there is no problem even if the flange 26b in front of the flange portion 26 is not screwed. In short, there is no problem with the installation strength of the drainage sleeve 20 that the protrusion degree of the front flange 26b is smaller than the protrusion degree of the side flange 26a.

In addition, in the embodiment described above, the shape of the front flange 26b of the flange portion 26 is an arc shape, but other shapes may be used, as long as the degree of protrusion is small, that is, as long as the tip position C (refer to FIG. 1( b)) Try to be as far back as possible to allow various shapes. For example, the front flange 26b may also have a shape in which the two bent portions 26ba of FIG. 1(b) are combined in a straight line and the front side is cut off. Furthermore, if the drain port insertion portion 25 is reliably installed and fixed to the drain port 7 within its vertical dimensions (within the range of the tapered surface), the front flange 26b may not be formed substantially. That is, the protrusion size of the front flange 26b may also be 0 (zero). In addition, the drainage port insertion portion 25 may not be tapered, but may be a pipe with a certain outer diameter.

Moreover, as shown in FIG. 1(b) and the like, a plurality of longitudinal ribs 28 having a triangular shape in a side view are formed along the circumferential direction at the female corners of the curved portion 24 and the flange portion 26. In this way, the longitudinal rib 28 can reinforce the flange portion 26 and prevent damage. Particularly on the front side, since the protrusion degree of the front flange 26b is small, the longitudinal rib 28 can be improved in strength.
