Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage socket, and more particularly, to a ball portion for retaining washing water as non-washing water when not being washed, and new washing water supplied to the ball portion to the outside together with the stored water. The present invention relates to a drainage socket connected to a flush toilet having a drainage channel that is a pipe for discharging water to the drainage pipe, and communicating the drainage channel with a sewage pipe provided outside.

[0002]

2. Description of the Related Art In connection with a method of connecting a toilet and a sewage pipe,
In recent years, the method performed through a drain socket has become mainstream. Specifically, after connecting a drain socket having a tubular flow path to a sewage pipe that has been set up on a floor or the like on the building side, insert the end of the toilet drain channel into the drain socket from above. . Thereby, the drainage channel of the toilet and the sewage pipe communicate with each other through the flow path of the drainage socket, and the waste and water in the toilet can be discharged to the sewage pipe.

[0003] The drainage socket has a function as a connecting member between the toilet and the sewage pipe (hereinafter referred to as a connecting function) and a function to promote a siphon action generated in the toilet. This function is realized by providing a portion of the flow passage of the drainage socket in which the cross-sectional area of the flow passage is smaller than the cross-sectional area of the flow passage at the inlet portion (hereinafter, this portion is referred to as a throttle portion). That is, since the resistance is given to the stored water or the washing water flowing from the drainage channel when passing through the throttle, the stored water or the washing water stays in the vicinity of the throttle and moves toward the dirty water pipe of the washing water. The falling speed of the is slowed down. For this reason, the toilet drainage channel is likely to be full, and as a result, it is possible to maintain the siphon action for a relatively long time even with a small amount of water. Such a drain socket function is hereinafter referred to as a siphon continuation function.

[0004]

However, the floor or wall on which the toilet is installed (hereinafter referred to as the installation surface)
The distance from to the end of the drainage channel varies depending on the type of toilet installed. Therefore, in order to enable installation of such various types of toilet bowls, conventionally, it is necessary to prepare a plurality of drainage sockets having different heights as a product, and it is necessary to efficiently reduce the number of product types. Could not.

Further, since toilets are individually designed or manufactured by a number of companies around the world, it is practically difficult to prepare drain sockets corresponding to all toilets that can be installed in advance. . For example, when the distance from the installation surface of the toilet to the end of the drainage channel is longer than the length of the drainage socket, measures such as laying a plate or the like having a thickness that is not enough for the length below the drainage socket, etc. Need
This was a factor that hindered construction efficiency. On the other hand, if the distance from the installation surface of the toilet to the end of the drainage channel is shorter than the length of the drainage socket, the method of connecting the toilet to the wastewater pipe must be changed to a method using a flange. It was inconvenient. As described above, the connection function of the drain socket described above cannot be performed depending on the type of the toilet bowl to be connected.

Further, in the conventional drainage socket, a cylindrical hollow portion formed in the socket is used as a water flow path, and the position of the throttle provided in this flow path is determined for each construction site. It could not be changed. For example, if the installed toilet is a toilet that uses the siphon action to perform cleaning, it is better to change the position of the throttle section below the floor surface to suction the pool water and wash water that occurs after the siphon action occurs. Although it is possible to increase the power, such a change could not be made in the past. As described above, in the conventional drain socket, even if the siphon effect is maintained for a long time by the siphon continuation function, a considerable loss occurs in the suction power of the stored water and the washing water caused by the continuation.

Therefore, the present invention has the following structure to solve the above-mentioned problems and to provide a drainage socket that can respond to various types of toilets to be installed and the situation at the installation site.

[0008]

The drain socket according to the present invention comprises a ball portion for retaining washing water as non-washing water when not washing, and a new washing water supplied to the ball portion. It is connected to a flush toilet having a drain which is a pipe for discharging to the outside together with water, and the drain communicates with a sewage pipe provided outside, and drains or flushes water from the drain. In the drainage socket flowing through the sewage pipe, the drainage socket is constituted by two or more members separable in the flow direction of the stored water or the wash water.

As described above, the drain socket is composed of two or more members that can be separated in the flowing direction of the stored water or the washing water, so that the flow path of the stored water or the washing water can be varied depending on the combination of the members. It can be in the form.

[0010] It is also preferable that the drainage socket is provided with a variable means for varying the length of the drainage or washing water in the flow direction. This makes it possible to connect the toilet and the sewage pipe in a plurality of forms. Therefore, the drainage socket can be shared.

[0011] At least two members that can be separated in the flowing direction of the stored water or the washing water are at least a first member which is a member disposed on a floor or a wall surface provided with a sewage pipe; Constructed from a second member combined with the member, comprising a positional relationship changing means for changing the positional relationship between the first member and the second member, by changing the positional relationship by the positional relationship changing means, It is also desirable to vary the length of the drainage socket in the flowing direction of the stored water or the washing water. In this case, the length of the drain socket based on the floor surface or the wall surface can be changed. Therefore, one toilet with a different distance from the floor or wall to the drain
It becomes possible to connect to the sewage pipe with different kinds of drainage sockets, and the workability is further improved.

If at least one of the first member and the second member is provided with a display for displaying information about the length of the drainage socket, the length of the drainage socket can be adjusted. This can be performed while checking the extent to which the total length of the socket is changed, and the workability associated with the adjustment is further improved. In addition, the display unit may display the value of the distance from the floor or wall provided with the sewage pipe to a position where the drain socket is connected to the drain, as information on the variable drain socket length. Is also good.
In this case, in order to properly connect the drainage channel of the toilet and the drainage socket, it is not necessary to adjust the dimensions while aligning the drainage channel of the toilet and the drainage socket. The value of the distance from the floor or the wall surface to the position where the drainage socket is connected to the drainage channel is measured in advance, and the dimensions of the drainage socket need only be adjusted according to the measured value. Therefore, the adjustment work becomes smoother.

A first flow path forming member which forms a flow path communicating with at least the end of the drainage channel, and a first flow path forming member; The member is configured as a separate body, and configured from a second flow path forming member that is a member that extends the flow path formed by the first flow path forming member further downstream, and the second flow path forming member A flow path changing means for changing the length of the flow path to be extended, and by changing the length of the flow path extended by the second flow path forming member by the flow path changing means, It is also desirable to vary the length of water or wash water in the flow direction. In this case, the flow path length of the drain socket can be changed to a desired length.

The second flow path forming member is constituted by a plurality of members, and the length of the flow path extended by the second flow path forming member can be changed by a combination of the plurality of members. This is preferable in that the flow path length can be changed by a simple operation.

The second flow path forming member is provided with a mark indicating the cutting position of the member in advance, and the second flow path forming member is cut based on the mark, so that the second flow path forming member cuts the second flow path forming member. It is also desirable to adopt a configuration in which the length of the extended flow path is changed. With such a configuration, the flow path of the drain socket can be changed to a suitable length by cutting, and the cutting operation can be performed smoothly. In addition, the second flow path forming member, a member that can extend the flow path formed by the first flow path forming member below the installation surface of the toilet,
The value of the distance that the second flow path forming member extends below the installation surface of the toilet may be displayed in advance near the mark. In this case, the length of the second flow path forming member can be determined so as not to interfere with the sewage pipe below the installation surface of the toilet.

The second flow path forming member is detachably attached to a predetermined portion of the drain socket, and the length of the flow path extended by the second flow path forming member is determined by the mounting position of the second flow path forming member. May be changed by changing. This makes it possible to change the flow path length of the drain socket with a simple operation.

[0017] As two or more members separable in the flowing direction of the stored water or the washing water, a first flow path forming member which is a member for forming a flow path communicating with the end of the drainage channel; Is configured as a separate body, and has a second flow path forming member that is a member extending the flow path formed by the first flow path forming member further downstream, and the first flow path forming member, the sewage pipe is A first member, which is a member arranged on the provided floor or wall surface, and a second member combined with the first member, and a flow path extended by the second flow path forming member. A flow path changing means for changing the length, and a positional relation changing means for changing a positional relation between the first member and the second member, wherein the length of the flow path extended by the second flow path forming member The drainage socket is changed by changing the By changing the positional relationship between the first member and the second member by the positional relationship changing means while varying the length of the stored water or the wash water in the flow direction, It is also appropriate to adopt a configuration in which the length of the washing water in the flow direction is variable. According to this configuration, it is possible to freely change both the length of the drain socket and the flow path length of the drain socket based on the floor surface or the wall surface. Therefore, the applicable range of the drain socket can be widened. For example, even if the type of toilet bowl to be installed and the state of the installed sewage pipe are different at each installation site, drainage can be adjusted by adjusting the height of the drain socket from the floor surface and the length of the drain socket flow path. The socket can be suitably mounted.

The second flow path forming member may be provided with a throttle, which is a portion for reducing the cross-sectional area of the member from the inlet of the member, or the position of the throttle may be freely adjusted. Desirable in point. By adjusting the position of the aperture,
The strength of the suction force of the stored water and the washing water generated after the occurrence of the siphon action can be determined to a desired level in consideration of the type of the installed toilet and the state of the installed sewage pipe.

The present invention can be configured as a flush toilet provided with the above drain socket. Further, the invention may be configured as a flush toilet connected to the above drain socket. For example, in a flush toilet connected to a drain socket provided with the above distance changing means, the distance from the floor or wall to the end of the drainage channel is changed by changing the length of the drain socket with respect to the floor or wall. Since the height is adjusted, the height of the end of the drainage channel can be relatively freely designed or manufactured when designing or manufacturing the toilet. Also,
In the flush toilet connected to the drainage socket provided with the above-mentioned flow path changing means, by changing the flow path length of the drainage socket, the guide path to the sewage pipe of stored water and washing water, the retention state of stored water and washing water. It is not necessary to provide a complicated structure in the toilet itself to ensure the cleaning performance of the toilet, because it can be changed.

[0020] The socket flow path extending member of the present invention is a member that connects the end of the drainage channel of the toilet to a drainage socket that communicates with a sewage pipe provided outside, and a flow path formed inside the drainage socket. It is a socket channel extension member which is a member which extends a path further downstream, and the point is that two or more numerical values indicating the length of extension of the channel are displayed.

According to the socket flow path extending member having such a configuration, when extending the flow path length of the drain socket, the length of the flow path extension can be easily determined. In this case, if different numerical values are displayed as two or more numerical values for each type of toilet and the installation conditions of the toilet, the flow path in the drain socket can be extended to a suitable length.

0, the main body member 71 is covered with four engaging pieces 89a, 89p.
FIG. 6 shows a front view of the drainage socket 60 when is engaged with the lowermost lateral grooves 82c and 82r. As shown in FIG. 6, in a state where the base member 80 and the main body member 71 are combined, the protruding engaging piece 89p, the lateral groove 82r with which the protruding engaging piece 89p is engaged, and the lateral groove 82r.
A “scale indicating a height of 130 mm” engraved next to is exposed through a window 88 formed by hollowing out a part of the outer peripheral front surface of the main body member 71 horizontally. That is, when the four engagement pieces 89a and 89p are engaged with the lowermost lateral grooves 82c and 82r, the height from the floor surface FL of the drain socket 60 to the installation surface 71b is 130 mm, which indicates this state. To this end, a protruding engagement piece 89p disposed at a position corresponding to the “scale indicating a height of 130 mm” is shown through the window 88.

FIG. 6 shows the drainage socket 6 shown in FIG.
0 shows the same state as when viewed from the front (that is, the surface located on the distal end side of the flush toilet 10 when attached to the flush toilet 10). In the flush toilet 10 shown in FIG. 1, the height from the floor surface FL at the installation location of the flush toilet 10 to the end of the descending path 33 is about 130 mm. For this reason, as shown in FIG. 6, the drain socket 60 is in the state where the height from the floor surface FL to the installation surface 71b is the lowest (130 mm in height).
State).

The height of the drain socket 60 from the floor surface FL is adjusted as follows. When the main body member 71 engaged in the lateral grooves 82c and 82r is rotated in a counterclockwise direction by a force equal to or greater than a predetermined value, the four engaging pieces 89a and 8
9p moves over the convex portion 81 to the position of the vertical grooves 82b and 82q. Thereby, the four engagement pieces 89a, 89
The engagement state of p is released, and the main body member 71 is
It will be movable up and down along 82q. Since the drain pipe 90 is weakly sandwiched between the ribs 66, the rib 66 slides on the surface of the drain pipe 90 when the main body member 71 is moved up and down. Therefore, the drain pipe 90 itself does not move up and down with the movement of the main body member 71.

Next, the main body member 71 is moved up and down to a desired position. Whether or not the user has moved to the desired position can be confirmed by referring to the above-mentioned "scales corresponding to the numerical values". For example, the height of the drain socket 60 from the floor surface FL is 1 shown in FIG.
When raising from the state of 30 mm to 200 mm, the main body member 71 may be raised until the position of the protruding engagement piece 89p comes to the position of “scale indicating 200 mm”.

The window 88 is slightly open in the direction in which the protruding engagement piece 89p engages with the lateral groove 82r (to the left in FIG. 6). For example, in FIG. 6, a large opening is formed such that a margin is formed on the left side of “1” which is the first character of the numerical value indicating the height of the drain socket 60 from the floor surface FL. I have. Therefore, even when the position of the window portion 88 moves counterclockwise with the rotation of the main body member 71 in the counterclockwise direction during the height adjustment, the engagement is released and the vertical groove is released. 82
All digits of the numerical value indicating the height of the drainage socket 60 appear through the window 88 together with the protruding engagement piece 89p located at q. Therefore, even during the adjustment of the height of the drain socket 60 from the floor surface FL, it is possible to confirm to which position the main body member 71 has moved while referring to the numerical values.

FIG. 7 shows a state of the drain socket 60 when the height of the drain socket 60 from the floor surface FL is adjusted to 200 mm. Since the protruding engagement piece 89p and the window 88 are both formed on the main body member 71, the main body member 71
Of the projection-like engaging piece 89p and the window 88
Also move up and down. Therefore, as shown in FIG. 7, when the height of the drain socket 60 from the floor surface FL is set to 200 mm, the projecting engagement piece 8 that has moved upward together with the window 88.
9p engages in the uppermost lateral groove 82r, and the window 88
A projecting engagement piece 89p arranged at a position corresponding to “a scale indicating a height of 200 mm” appears. As described above, the height of the drain socket 60 from the floor surface FL is represented by the position of the protruding engagement piece 89p on the front of the drain socket 60.

In the manner described above, the floor surface F of the drain socket 60
After adjusting the height from L to the height from the floor surface FL to the end of the descending passage 33, a sealing material (not shown) for preventing water leakage is attached to the descending passage fitting portion 71a, and the descending passage fitting is performed. The end of the descending path 33 of the flush toilet 10 is inserted into the joint portion 71a. As a result, the descending path 33 of the drain socket 60 and the drain pipe 90
Installation to the is completed.

As described above, according to the drainage socket 60,
By adjusting the height of the drain socket 60 from the floor surface FL, the total length of the drain socket 60 can be changed. In addition, the total length of the drainage socket is the drainage socket 60.
The distance from the uppermost position on the descending path 33 side to the position on the drainage pipe 90 side. In FIG. 2, the base member is in contact with the floor FL from the top of the descending path fitting portion 71a. 80 means the distance l1 to the bottom surface.

FIG. 8 shows a longitudinal section when the drainage socket 60 whose height from the floor FL is adjusted to 200 mm is connected to another flush toilet 510. This flush toilet 510 is
Like the flush toilet 10 described above, it has a drainage channel including a connection channel, an ascending channel, and a descending channel 533. On the other hand, the height from the floor surface FL to the end of the descending path 533 is the flush toilet 1
0, which is about 200 mm.

In the state shown in FIG. 8, the second annular projection 6
The four engagement pieces 89a and 89p at the tip of the eight are engaged with the uppermost lateral grooves 82c and 82r. Thus, the main body member 71 is combined with the base member 80. The main body member 71 is connected to the drain pipe 90 by sandwiching the drain pipe 90 with a rib 66 bonded to the lowermost part of the second annular concave portion 62. The main body member 71 is connected to the descending path 533 by receiving the end of the descending path 533 having a height of about 200 mm from the floor surface FL on the installation surface 71b of the descending path fitting portion 71a. . in this way,
Even when the height of the drain socket 60 is adjusted and the total length of the drain socket 60 is changed, the descending path 533 and the drain pipe 90 are satisfactorily connected via the drain socket 60.

The main body member 71 and the base member 8 in FIG.
When the positional relationship with 0 is compared with the case shown in FIG. 2, the positional relationship between them is changed so as to be away from each other. Specifically, the distance from the floor surface FL to the installation surface 71b of the main body member 71 is 200 mm from the value of 130 mm.
mm. As a result, the distance l from the top of the descending path fitting portion 71a to the bottom of the base member 80 is obtained.
2 is 70 mm longer than the distance 11 shown in FIG.

In the first embodiment described above, the drain socket 60 is divided into a plurality of members, that is, the main body member 71 and the base member 80 which can be separated in the direction in which the main conduit 73 extends. In addition, the flow path of the stored water RW or the washing water can be variously configured. Further, since the entire length of the drain socket 60 can be freely changed, the flush toilet 10 and the drain pipe 90 can be connected in a plurality of forms, and the drain socket 60 can be shared.

In the first embodiment, such a change in the entire length of the drain socket 60 is realized by changing the height of the drain socket 60 from the floor surface FL. Therefore, it is possible to connect toilets having different heights from the floor surface FL to the end of the descending path 33 using the same drainage socket 60, and the workability is further improved.

The drainage socket 60 of the first embodiment is
On the side surface of the main body member 71, the value of the height from the floor surface FL of the drainage socket 60 to the installation surface 71b after the height adjustment,
Display so that it can be viewed. Therefore, the height of the drainage socket 60 can be adjusted while checking the degree to which the height is changed, and the workability associated with the adjustment is further improved. For example, the scale of the drain socket 60 is set to the flush toilet 1
A good connection state can be ensured by adjusting to the design dimension indicating the height from the descending road of 0 to the floor surface FL. Therefore, at the construction site, the floor FL to the installation surface 7
There is no need to measure the dimension up to 1b or the dimension up to the end of the descending path 33 each time, or to adjust the dimension of the drainage socket 60 while aligning it with the flush toilet 10, so that the adjustment operation becomes smoother.

In the first embodiment, the height value from the floor surface FL of the drainage socket 60 to the installation surface 71b is determined by the projection engaging piece 8
Represented by 9p position. Therefore, the height value can be displayed without adding a special mechanism for display.

The clamping of the drain pipe 90 by the rib 66 described in the first embodiment is an example of a method of connecting the drain pipe 90 to the drain socket 60, and the drain pipe 90 is drained by using another method. It can be connected to the socket 60. For example, an elastic body other than rubber may be used as the rib 66. Further, the same material may be used for both the rib 66 and the drain socket 60, and may be formed integrally with the second annular recess 62. If the water passing through the drain socket 60 does not leak to the outside of the drain pipe 90, the water is inserted into the second annular recess 62 without fitting or bonding the drain pipe 90 and the drain socket 60. You may just keep it.

In the first embodiment, the drain pipe 90 is connected to the second annular recess 62 of the main body member 71 of the drain socket 60. However, the same structure as the second annular recess 62 is formed in the base member 80. Alternatively, the drain pipe 90 may be connected to the base member 80 of the drain socket 60.

Further, in the first embodiment, the main body member 71
The engagement structure between the four engagement pieces 89a, 89p and the respective engagement portions 82a, 82p of the base member 80 is merely an example of a structure for changing the positional relationship between the main body member 71 and the base member 80. The positional relationship between the main body member 71 and the base member 80 may be changed using other structures. For example, one hole is formed in the main body member 71, and a plurality of holes are formed in the height direction of the base member 80, respectively.
After aligning the position of the hole formed in 1 with the position of the hole formed in the base member 80, a configuration in which a pin penetrates these holes can be considered.

In the first embodiment, the base member 80 is
The base member 80 does not necessarily need to be fixed to the floor surface FL.
The base member 80 may be simply placed on the floor FL.
In such a case, the height adjustment of the drain socket 60 can be performed after the base member 80 is placed on the floor surface FL as described above.
If the operation is performed before placing at L, the working efficiency becomes better. That is, if the drain member 60 is adjusted to a desired height by previously combining the base member 80 and the main body member 71, and then the base member 80 combined with the main body member 71 is placed on the floor surface FL. Good.

Next, a second embodiment of the present invention will be described. FIG. 9 shows a drain socket 8 according to a second embodiment of the present invention.
It is explanatory drawing which shows the vertical cross section when the flush toilet 810 and the drain pipe 890 are connected using 60. The flush toilet 810 and the drain socket 860 shown in FIG. 9 include components substantially common to the flush toilet 10 and the drain socket 60 described above. In FIG. 9, the last two digits of the reference numerals for the common parts are represented by the same numerals as in FIG.

The drain socket 860 has the same base member 880 and main body member 871 as in the first embodiment. Therefore, the height from the floor surface FL to the installation surface 71b of the main body member 71 can be adjusted.

The drainage socket 860 of the second embodiment is composed of three members: a base member 880 and a main body member 871, and a drain pipe socket member 72 mounted on the main body member 871. The base member 880 is
The main body member 8 corresponds to a first member described in the claims.
71 corresponds to the first member or the first flow path forming member described in the claims. The drain pipe socket member 72 includes:
It corresponds to the second flow path forming member described in the claims.

A hollow and cylindrical main conduit 873 is formed below the descending passage fitting portion 71a. This main line 87
3 is a flow path for the stored water, washing water, and filth flowing from the descending path 33. The main line 873 is provided with the main line 73 of the first embodiment.
There are provided two types of throttle units similar to the above.

As shown in FIG. 9, the drain pipe socket member 72 is inserted into a first annular concave portion 864 formed around the outside of the main conduit 873. The drain pipe inner socket member 72 is configured by a combination of two members, that is, a substantially cylindrical first cylindrical portion 72b and a cylindrical second cylindrical portion 72c. Specifically, one drain pipe socket member 72 is formed by bonding the upper end of the second cylindrical portion 72c to the end of the first cylindrical portion 72b.

The drain pipe socket member 72 is bonded to a desired position on the outer peripheral wall of the first annular concave portion 864. By this bonding, the socket member 72 in the drain pipe is connected to the main body member 87.
Becomes one with 1. Due to the adhesion of the drain pipe inner socket member 72, the first tubular portion 72b forms an extended conduit 75 having a conduit diameter larger than that of the main conduit 873 as a continuous flow passage with the main conduit 873. In addition, the second tubular portion 72c is connected to the expansion pipe 7
As a flow path that is continuous with 5, a pipe 76 having the same diameter as the main pipe 873 is formed. As described above, the drain pipe socket member 72 extends the main pipe line 873 formed in the main body member 871, which is a flow path of the stored water RW, the cleaning water, and the filth, further downstream. As shown in FIG.
The dirt passage is extended by the socket member 72 in the drain pipe to a position below the floor surface FL in the drain pipe 890.

The first cylindrical portion 72b has a non-throttled portion 7 which is a portion maintained in substantially the same cross-sectional area as the start end of the first cylindrical portion 72b.
2p and the cross-sectional area at the end of the non-throttled portion 72p
The first throttle portion 72q which is a portion gradually reduced in the terminal direction of 2b
Is provided. The end of the first cylindrical portion 72b is connected to the expansion pipe 7
After projecting in the horizontal direction toward the center of No. 5, it extends vertically downward, and the cross-sectional area of the first cylindrical portion 72b is also reduced at the end of the first cylindrical portion 72b. The end portion of the first cylindrical portion 72b formed in this manner is hereinafter referred to as a second throttle portion 72r.

The drain socket 86 having the above configuration
0, the body member 87 of the socket member 72 in the drainage pipe.
By changing the mounting position to the drain socket 8
The total length of the 60 can be changed. In FIG. 9, the total length of the drain socket is a distance l3 from the top of the descending passage fitting portion 971a to the end of the second cylindrical portion 72c of the drain pipe inner socket member 72.

The main body member 87 of the drain pipe socket member 72.
FIG. 10 shows a state when the mounting position on the device 1 is changed.
As shown in FIG. 10, the first cylindrical portion 72b of the drain pipe socket member 72 is different from the case of FIG.
4 is bonded to the lower side of the outer peripheral wall. For this reason, the drain pipe socket member 7 extends from the top of the descending path fitting portion 871a.
The distance 14 to the end of the second second cylindrical portion 72c is longer than the distance 13 shown in FIG.

The second tubular portion 72c of the drain pipe socket member 72 has entered a deep position in the drain pipe 890 by bonding the drain pipe socket member 72 to the lower side. Therefore, the first throttle unit 72q and the second throttle unit 72
r is arranged at a position lower than the floor surface FL as a reference. Further, the lengths of the expansion pipe 75 and the same diameter pipe 76 which are the flow paths extending the main pipe 873 are longer.

In the second embodiment described above, the drain socket 60 is constituted by dividing the main body member 871, the base member 880, and the drain pipe socket member 72 into a plurality of members that can be separated in the direction in which the main conduit 873 extends. Therefore, depending on the combination of the members, the flow path of the stored water RW and the washing water can be variously formed. The drain socket 860 of the second embodiment also allows the total length of the drain socket 60 to be freely changed. Therefore, the flush toilet 810 and the drain pipe 890 can be connected in a plurality of forms, and the drain socket 860 can be shared.

In the drain socket 860 of the second embodiment, the entire length of the drain socket is changed by changing the position where the socket member 72 in the drain pipe is mounted on the main body member 871. Therefore, the length of the flow path of the drain socket 860 can be changed to a desired length. In particular, in the second embodiment,
The drain pipe inner socket member 72 is formed separately from the main body member 871, and the length of the flow path is changed to a desired length simply by changing the bonding position of the drain pipe inner socket member 72 to the first annular concave portion 864. It is possible to easily change the flow path length.

Further, since the drain pipe inner socket member 72 is constituted by a combination of a plurality of members, that is, the first cylindrical portion 72b and the second cylindrical portion 72c, the work involved in changing the flow path length can be simplified. For example, the first annular recess 864
And three patterns of bonding both the first cylindrical portion 72b and the second cylindrical portion 72c, bonding only the first cylindrical portion 72b, and not bonding both the first cylindrical portion 72b and the second cylindrical portion 72c. By simply selecting one pattern from the above, a desired flow path length can be realized.

The drain pipe socket member 72 described above.
Is provided with two throttle units, a first throttle unit 72q and a second throttle unit 72r. Therefore, the position of the throttle can be freely determined in consideration of the type of the toilet and the state of the drain pipe 890.

For example, when the drain socket 860 is used for a siphon type toilet having a small amount of flush water, the drain pipe socket member 72 is placed in a state as shown in FIG. 10 (adhered to a position below the first annular recess 64). State). In this case, the point where water stays in the expansion pipe 75 is located downward, and the head difference between the staying point and the vicinity of the weir increases. Therefore, it is possible to more efficiently utilize the suction force of the stored water and the washing water generated by the siphon action, and to increase the suction force.

In the above case, the flush toilet 81
For example, the drain pipe 89 is located on the upper floor.
In the case where the rising height from the horizontal pulled state of 0 (that is, the depth from the upper end of the drain pipe 890 to the inner bottom surface) is low, the first cylindrical portion 72b of the socket member 72 in the drain pipe is provided.
Only the first cylindrical portion 72b may be bonded above the first annular concave portion 864. In this way, it is possible to avoid interference with the drain pipe 890 while setting the point where water stays in the expansion pipe 75 downward. Accordingly, the flushing performance of the toilet can be improved regardless of the state of the drain pipe 890 being started up.

When the drain socket 860 is used for a non-siphon type toilet, the drain socket 860 is used.
It is not necessary to attach the drain pipe socket member 72 to the first annular concave portion 864 because it is not necessary to cause water to stay therein. Therefore, a common drainage socket 860 can be provided for a non-siphon type toilet and a siphon type toilet.

According to the drain socket 860 of the first embodiment, both the height of the drain socket 860 from the floor surface FL and the length of the flow path of the drain socket 860 can be changed. Therefore, even when the type of the installed toilet and the state of the installed sewage pipe differ from one installation site to another, a constant cleaning performance can be ensured.

For example, when the above drain socket 860 is used for two types of siphon toilets having substantially the same amount of washing water and different heights from the floor surface FL to the end of the drainage channel,
The two types of siphon-type toilets can be provided with substantially the same cleaning ability. Specifically, the drain socket 86
While adjusting the height of the floor 0 from the floor FL,
The drain pipe socket member 72 may be brought into contact with the first annular concave portion 864 so that the lower ends of the drain pipe socket members 72 are located at the same position. In this case, since the flush water amount and the water retention point in the socket are the same for both toilets, uniform flushing performance can be obtained.

Next, a third embodiment of the present invention will be described. FIG. 11 is an explanatory view showing a longitudinal section when the flush toilet 110 and the drain pipe 190 are connected using the drain socket 160 according to the third embodiment of the present invention. The flush toilet 110 and the drain socket 160 shown in FIG. 11 include components substantially common to the flush toilet 10 and the drain sockets 60 and 860 described above. In FIG. 8, for each common part,
The last two digits of the code are represented using the same numerals as in FIGS.

The drainage socket 160 of the third embodiment is
Unlike the embodiment, the base member 80 and the main body member 71 have a non-separable structure. Therefore, the drain socket 160
Is composed of two members, a main body member 171 and a socket member 172 in the drain pipe attached to the main body member 171.

As shown in FIG. 11, the main body member 171 has a main conduit 17 serving as a flow path for stored water RW, washing water, and dirt.
3 are formed. The main body member 171 corresponds to a first flow path forming member described in the claims. Further, the drain pipe socket member 172 is bonded to the main body member 171 to extend the main pipe 173 to a further downstream position below the floor surface FL in the drain pipe 190. The drain pipe inner socket member 172 corresponds to a second flow path forming member recited in the claims.

As in the second embodiment, the drain pipe socket member 172 is constituted by a combination of two members, that is, a substantially cylindrical first cylindrical portion 172b and a cylindrical second cylindrical portion 172c. By bonding the upper end of the second cylindrical portion 172c to the end of the cylindrical portion 172b, one socket member 172 in the drain pipe is formed.

As shown in FIG. 11, the first cylindrical portion 172b serves as a flow path that is continuous with the main
An expansion pipe 175 having a pipe diameter larger than that of No. 3 is formed. In addition, the second cylindrical portion 172c forms the same diameter pipe 176 having substantially the same diameter as the main pipe 173 as a flow path that is continuous with the expansion pipe 175. In addition, the socket member 1 in the drain pipe
72, a non-throttle portion 172p, a first throttle portion 172q, and a second throttle portion 172r are formed as in the second embodiment.

Main body member 1 of drain pipe socket member 172
The mounting method to the base 71 is different from that of the second embodiment as described below. That is, an annular convex portion 179 is formed outside the main conduit 173 of the main body member 171.
A flange 179 a is formed integrally with the annular projection 179 on the inner peripheral wall of 79. The first cylindrical portion 172b of the socket member 172 in the drain pipe described above is bonded to the flange portion 179a. Accordingly, in FIG. 11, the total length of the drainage socket is the distance l from the top of the descending passage fitting portion 171a to the end of the second tubular portion 172c of the socket member 172 in the drainage pipe.
It becomes 5.

The drain pipe 190 rising from the floor surface FL is inserted into the flange 179a to which the socket member 172 in the drain pipe is adhered. This drain pipe 190
Is bonded to the inner peripheral wall of the annular projection 179. By this bonding, the drain socket 160 and the drain pipe 190 are connected.

Further, a mark indicating a position at which the first cylindrical portion 172b is cut is engraved on the first cylindrical portion 172b of the drain pipe socket member 172. This is shown in FIG. FIG. 12 is an explanatory diagram illustrating an appearance of the first cylindrical portion 172b.
As shown in FIG. 12, on the outer peripheral surface of the first cylindrical portion 172b,
Three scale lines are cut at a pitch of 20 mm in the height direction.

In the vicinity of each of these scale lines, a numerical value indicating the length of the first cylindrical portion 172b extending below the floor surface FL when the first cylindrical portion 172b is bonded to the flange portion 179a. Carved. Specifically, as shown in FIG.
Numerical values from 40 mm to 100 mm are shown in units of 20 mm. For example, when the first cylindrical portion 172b is bonded to the flange portion 179a without cutting, the first cylindrical portion 172b
The terminal end 172g of b is arranged at a position 100 mm below the floor surface FL. In addition, 40mm, 60mm, 80m
Each numerical value m indicates the length of the first cylindrical portion 172b that extends below the floor surface FL when the first cylindrical portion 172b is cut at the position of the scale line above each numerical value. ing. For example, when the first cylindrical portion 172b cut at the position of the scale line of 60 mm is adhered to the flange portion 179a,
The terminal end 172g of the first cylindrical portion 172b is 6 degrees higher than the floor surface FL.
It is arranged at a position below 0 mm. Of course, as this numerical value, the first cylindrical portion 172b extending below the floor surface FL
It is also possible to indicate the length of the second cylindrical portion 172c.

Since these numerical values are displayed on the side surface used as the first cylindrical portion 172b when cut at each scale line, even when the first cylindrical portion 172b is bonded after cutting, The length of the first cylindrical portion 172b can be confirmed. In FIG. 11 described above, the first tubular portion 172b that is not cut is connected.

The first cylindrical portion 172b is cut along a scale line of 60 mm and bonded to the second cylindrical portion 172c, and the drain pipe socket member 172 formed by this bonding is connected to the flange portion 17.
FIG. 13 shows a state in which the camera is mounted on 9a. As shown in FIG. 13, since the cut first cylindrical portion 172b is adhered, the distance 16 from the top of the descending path fitting portion 171a to the end of the second cylindrical portion 172c of the drain pipe inner socket member 172 is: It is shorter than the distance 15 shown in FIG. Further, below the floor surface FL, a first cylindrical portion 172b is provided.
The length of the second cylindrical portion 172c is added to the length of 60 mm, which is the length of the socket member 172 in the drain pipe.

The drain socket 1 of the third embodiment described above.
60 allows the length of the drain pipe socket member 172 projecting below the floor surface FL to be changed by cutting the first cylindrical portion 172b. Therefore, the flow path of the drain socket 60 can be changed to any length. In addition, since the scale position indicates the cutting position of the first cylindrical portion 172b on the first cylindrical portion 172b, the cutting operation becomes smooth. Further, the first cylindrical portion 172 which extends below the floor surface FL when cut at the position of each scale line near the scale line.
Since the numerical value indicating the length of b is displayed, the length of the drain pipe socket member 172 can be determined so that the drain pipe 190 rises from the floor surface FL and does not interfere inside the drain pipe 190. .

FIG. 1 shows a modification of the first cylindrical portion 172b.
It is shown in FIG. The first cylindrical portion 272b shown in FIG. 14 does not have the non-constricted portion 172p as in the third embodiment, and has a first constricted portion 272q in which the cross-sectional area of the starting end of the first cylindrical portion 172b is gradually reduced toward the terminal end. Is formed.

Further, on the outer peripheral surface of the first cylindrical portion 272b, three scale lines are engraved in the height direction as marks indicating positions where the first cylindrical portion 272b is cut. Above each of these scale lines, a numerical value indicating the inner diameter of the first cylindrical portion 272b at the cutting position of each scale line is engraved. Specifically, as shown in FIG.
The numerical value m is shown. These numbers are
Since the first cylindrical portion 272b is displayed on the side surface used as the first cylindrical portion 272b when cut at each scale line, even when the first cylindrical portion 272b is bonded after the cutting, the first cylindrical portion 272b is bonded.
The inner diameter at the end of 2b can be confirmed.

If the first cylindrical portion 272b is cut along an arbitrary scale line and attached to the flange portion 179a shown in FIG.
The degree of throttling in the first cylindrical portion 272b can be adjusted. For example, when cutting at a position with an inner diameter of 50 mm,
Since the first cylindrical portion 272b is shortened, the accumulated state of the stored water RW and the washing water when passing through the first cylindrical portion 272b is weakened. As described above, according to the first cylindrical portion 272b, the stagnation state in the drain socket 160 can be created according to the performance of the toilet bowl to be mounted.

In the second and third embodiments, the drain pipe socket members 72, 172 are connected to the first cylindrical portions 72b, 17b.
2b and the second cylindrical portion 72c, 172c are divided into two parts. However, the drain pipe socket members 72, 172 may be formed by one member.

Also, the drain pipe socket members 72 and 172 are provided.
Can be divided into three or more parts.
For example, in the second embodiment, the flange 179a is
9, the member having the same shape as the flange 179a is formed separately from the annular convex portion 179, and the flange 179a, the first cylindrical portion 172b, and the second cylindrical portion 172c are formed.
Can be considered as a configuration in which the combination of the above is mounted as the socket member 172 in the drain pipe on the annular convex portion 179.
This makes it possible to freely adjust the mounting position of the flange portion 179a on the annular convex portion 179. For example, collar 1
The mounting position of the 79a on the annular convex portion 179 is
If it is determined according to the rising height from the floor FL,
The drain pipe 190 is connected to the inner peripheral wall of the annular convex portion 179 and the flange portion 1.
Fits perfectly in the space enclosed by 79a. Therefore, even if the rising height of the drain pipe 190 is different for each installation site, the drain socket 160 can be mounted without cutting the drain pipe 190 in accordance with the drain socket 160.

In the second and third embodiments, the method of attaching the socket members 72 and 172 in the drain pipe to the main body members 71 and 171 employs a method of bonding. A configuration in which the position of the drain pipe socket member 72 is changed using another method may be used. For example, a configuration in which the drain pipe inner socket member 72 is slidably fitted to the peripheral wall of the first annular recess 64 can be considered.

The main pipelines 73 and 173 and the expansion pipeline 7
The degree of the throttle provided in 5,175 can be arbitrarily determined according to the shape of the flow path of the washing water. In addition, it is also possible to adopt a configuration in which a throttle is provided also in the same diameter pipes 76 and 176. Further, in the above embodiment, the main pipeline 73,
The center of 173 and the centers of the expansion conduits 75 and 175 may be eccentric.

In the above embodiment, the numerical value engraved on the side surface of the socket member 172 in the drain pipe is such that “when cut at the position of each graduation line, the drain pipe extends below the floor surface FL. A numerical value indicating “length of socket member 172” or “socket member 17 in drain pipe at cutting position”
Although the numerical value indicating the “inner diameter of 2” is shown, it is also desirable to indicate a numerical value or information based on a difference in the situation of the construction site and a difference in the type of the toilet installed.

For example, the distance from the floor FL on which the toilet bowl is installed to the drainage pipe drawn horizontally under the floor FL is 1 in a house.
It is considered that the value is about 800 mm when installed on the floor, and about 100 mm to 200 mm when installed on the second floor of the house. Therefore, these values are used as numerical values indicating “the length of the drain pipe socket member 172 that extends below the floor surface FL when cut at the position of each scale line”, and these values are used as the drain pipe socket member 172. If described on the side of the toilet, it will be possible for the toilet contractor to immediately determine the appropriate cutting position depending on the toilet floor,
There is no hesitating where to cut in the displayed mark. As a result, the drain socket can be mounted properly and smoothly.

In recent years, even with the same siphon toilet,
The amount of washing water varies greatly depending on the type or product number. Therefore, "When cutting at the position of each scale line,
Instead of numerical values indicating “the length of the drain pipe socket member 172 that extends below the floor surface FL” and “the inner diameter of the drain pipe socket member 172 at the cutting position”, the toilet bowl is placed near each scale line. Entering the part number allows the toilet contractor to immediately determine the appropriate cutting position based on the part number of the toilet bowl to be installed, as well as the drain socket that takes into account the difference in the amount of washing water for each toilet bowl. A suitable staying state can be secured.

Further, the above-described socket member 72 in the drain pipe,
If 172 is bundled and shipped with the flush toilet 10, the postponement of construction due to the absence of the drain pipe socket members 72, 172 and the loss of the drain pipe socket members 72, 172 at the construction site can be reliably prevented. Can be. Providing only the drain pipe socket members 72 and 172 as a single item is also preferable in that it is possible to take ex post measures when the state of the drain pipe 90 or the type of the flush toilet 10 to be installed cannot be changed. is there.

The embodiments of the present invention have been described with reference to the first to third embodiments. The present invention is not limited to such embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the gist of the present invention.

For example, the drain socket 60 of the above embodiment,
At 160, the terminal ends of the descending paths 33 and 133 are received by the installation surface 71b of the descending path fitting portion 71a.
The end of each of the descending paths 33 and 133 may not be in contact with the installation surface 71b.
It is sufficient to be located within the height range of 1a. The load of the flush toilets 10 and 110 is received on the floor surface FL, and the
This is because the load of the flush toilets 10 and 110 is not applied to 1b.

Further, the drain socket 60 of the above embodiment is
The present invention can also be applied to a case where the drain pipes 90 and 190 are lead pipes. In this case, an adapter that can be connected to a lead pipe is separately prepared, and the drain pipes 90 and 1 are connected through this adapter.
90 and the drain sockets 60 and 160 may be connected.

In the above embodiment, the case where the drain pipe 90 is floor drainage rising from the floor surface FL has been described as an example. However, in the present invention, the drain pipe 90 is taken out from the wall surface of the place where the flush toilet 10 is installed. It can also be applied to the case of Generally, there are two types of flush toilets: an S-trap specification in which the end of the drainage channel is directed toward the floor and a P-trap type in which the end of the drainage channel is directed toward the wall in response to the differences in building conditions for each building. Variations are provided. Even in the case of a toilet with a P trap specification, the distance from the end of the drainage channel to the wall surface may vary depending on the type of toilet. Further, in the case of wall drainage, the distance that the drainage pipe is taken out of the standing pipe behind the wall differs from place to place as in the case of floor drainage. Accordingly, if the connecting member for connecting the drain pipe taken out from the wall and the end of the drainage channel of the P-trap toilet is configured to have a variable overall length, the connecting member can be shared. This makes it possible to improve the workability of the toilet room as a whole.

In the above embodiment, the siphon jet toilet was described as an example, but the present invention can be applied to other types of toilets. For example, the present invention can be applied not only to a siphon-type toilet that causes a siphon action without ejecting washing water from a jet hole, but also to a flush-type toilet that does not use a siphon action and that flushes waste and stored water by a water force of the wash water. Can be. In the case where the drainage channel of the flush toilet is bent from the top to the bottom, the drainage channel becomes almost full when the toilet is washed, and a phenomenon similar to the siphon action may occur. In such a case, if the drainage sockets 860 and 160 of the present embodiment are mounted, the retention points of the stored water RW and the cleaning water can be arbitrarily adjusted by changing the mounting positions of the socket members 72 and 172 in the drainage pipe. Drain pipe 890,1 for stored water RW and cleaning water
The suction force in the 90 direction can be increased, and the cleaning ability can be further improved.

In the above embodiment, the case where the present invention is applied to a flush toilet such as a siphon-jet toilet is described as an example. However, the present invention is applied to a combination of the above flush toilet and other devices and members. You can also understand. For example,
Functions for realizing various functions such as local washing and heating Sanitary washing device combined with toilet seat, toilet kit device combined with storage cabinet and hand washing device, wall material, floor material and ceiling material as a structure in the toilet room Combined system toilet devices and the like are conceivable.
