Abstract
Description
本発明は便器本体の排出口と下水管につながる排水管とを接続する排水ソケットに関する。 The present invention relates to a drain socket for connecting a discharge port of a toilet body and a drain pipe connected to a sewer pipe.
排水ソケットに関しては、サイホン作用を高めるために各種工夫がなされている。例えば特許文献1には、排水ソケット全体を曲管状とするとともに、ソケット流路の上端開口の下部の内面に、流下する排水を受け止める排水受面と、受け止めた排水を内方に向けて導くための排水案内面を形成した内容が開示されている。 Regarding the drain socket, various devices have been devised to enhance the siphon action. For example, in Patent Document 1, the entire drainage socket is curved, and the drainage receiving surface for receiving the drainage flowing down to the inner surface of the lower part of the upper end opening of the socket channel and the received drainage are guided inward. The content of forming the drainage guide surface is disclosed.
また特許文献2には、排水ソケットの上部に別体として、洗浄水滞留手段を設け、この洗浄水滞留手段において洗浄水を一時的に滞留させてサイホンを発生させるようにした内容が内示されている。特に洗浄水滞留手段の流路断面積を洗浄水の流れる方向に沿って徐々に減少させることで、上記の効果を高めている。
図10(a)は排水ソケットによって便器本体の排出口と下水管につながる排水管とを接続した一般的な構造を示す図である。図10(a)に示すように従来はタンクの後方への飛び出しや便器の製作誤差の吸収などを考慮して、便器と壁面との距離をある程度大きくとっていた。 Fig.10 (a) is a figure which shows the general structure which connected the drainage pipe connected to the discharge port of a toilet bowl main body, and a sewer pipe by the drainage socket. As shown in FIG. 10A, conventionally, the distance between the toilet bowl and the wall surface has been increased to some extent in consideration of the rearward jump of the tank and the absorption of toilet manufacturing errors.
ところが最近ではタンク形状の変更、便器自体の製作精度の向上もあり、トイレ空間を広くするため、図10(b)に示すように、便器本体を壁側に寄せ、壁面から便器本体の先端までの寸法(前出)を小さくする試みがなされている。 Recently, however, the shape of the tank has been changed and the production accuracy of the toilet bowl itself has been improved. To widen the toilet space, as shown in FIG. 10 (b), the toilet bowl body is moved to the wall side, from the wall surface to the tip of the toilet bowl body. Attempts have been made to reduce the dimensions (above).
しかしながら、トイレの床面に開口する排水管の位置はそのままであるので、便器本体を後方にずらすと、便器本体の排出口と下水管につながる排水管との前後方向の距離が更に大きくなる。その結果、排水ソケット内の流路の屈曲がきつくなり、汚物の詰まりが発生しやすくなる。
また、屈曲がきつくなると射出成形によって排水ソケットを一体成形することが困難になってコストアップにつながる。
However, since the position of the drain pipe that opens on the floor of the toilet remains the same, if the toilet body is shifted rearward, the distance in the front-rear direction between the outlet of the toilet body and the drain pipe connected to the sewer pipe is further increased. As a result, the flow path in the drain socket becomes tight and the clogging of filth tends to occur.
In addition, if the bending becomes tight, it becomes difficult to integrally form the drain socket by injection molding, leading to an increase in cost.
特許文献1,2に開示される内容は、サイホンを効果的に発生させることについての開示はなされているが、便器本体の排出口と下水管につながる排水管との前後方向の距離が大きくなった場合についての対処に関しては何ら開示されていない。 The contents disclosed in Patent Documents 1 and 2 disclose that siphon is generated effectively, but the distance in the front-rear direction between the outlet of the toilet body and the drain pipe connected to the sewer pipe becomes large. There is no disclosure regarding how to deal with the case.
上記課題を解決すべく本発明に係る排水ソケットは、便器本体の排出口に連結される流入部と、床面の排水管に連結される流出部と、これら流入部と流出部との間に設けられるソケット流路とを備え、便器本体の前後方向を基準として、前記流入部に連続するソケット流路入口の中心は前記流入部の中心に対して前方に偏心し、前記流出部に連続するソケット流路出口の中心は前記流出部の中心に対して後方に偏心した構成とした。 In order to solve the above problems, a drain socket according to the present invention includes an inflow portion connected to a discharge port of a toilet body, an outflow portion connected to a drain pipe on a floor surface, and between the inflow portion and the outflow portion. A socket channel provided, and the center of the socket channel inlet continuous with the inflow portion is eccentrically forward with respect to the center of the inflow portion with respect to the longitudinal direction of the toilet body, and continues to the outflow portion. The center of the outlet of the socket flow path is decentered rearward with respect to the center of the outflow part.
上記構成とすることによって、便器本体の排出口と下水管につながる排水管との前後方向の距離が更に大きくなっても、実質的な偏心距離を小さくすることができ、サイホンは有効に発生し、また汚物の詰まりもない。 By adopting the above configuration, even if the distance in the front-rear direction between the outlet of the toilet body and the drain pipe connected to the sewer pipe is further increased, the substantial eccentric distance can be reduced, and siphons are effectively generated. Also, there is no clogging of filth.
前記流入部下端の後部でソケット流路入口との境界部には、棚部を形成することが好ましい。この棚部を形成すると、水が当って空気の流入が防止され、サイホンが有効に発生する。 It is preferable that a shelf is formed at the boundary between the rear end of the inflow portion and the socket flow path inlet. When this shelf is formed, water hits to prevent the inflow of air and siphon is effectively generated.
また、前記ソケット流路出口の前部には垂下部を形成することが好ましい。この垂下部を形成すると、下方からの空気の侵入が防止されサイホンが有効に発生する。 Moreover, it is preferable that a drooping portion is formed at the front portion of the socket flow path outlet. If this hanging part is formed, intrusion of air from below is prevented and siphon is effectively generated.
また、前記ソケット流路の前方内側面を上部曲面と下部曲面を連続して構成し、上部曲面はソケット流路内方に向かって膨出し、下部曲面はソケット流路外方に向かって膨出し、更にソケット流路の後方内側面は全体がソケット流路外方に向かって膨出した形状とすることが好ましい。 In addition, the front inner surface of the socket channel is formed by continuously forming an upper curved surface and a lower curved surface, the upper curved surface bulges inward of the socket channel, and the lower curved surface bulges out of the socket channel. Furthermore, it is preferable that the rear inner surface of the socket channel is shaped so that the whole bulges outward from the socket channel.
ソケット流路の前方内側面の上部曲面をソケット流路内方に向かって膨出せしめて絞り形状とすることで、ソケット流路内での空気の溜まりが防止され、より強力なサイホンが発生し、それが持続する。また、ソケット流路の前方内側面の下部曲面をソケット流路外方に向かって膨出せしることで、大きな汚物でも詰まることなく通過し、更にソケット流路の後方内側面の全体をソケット流路外方に向かって膨出せしめることで、流路に汚物が衝突してもスムーズに流れ、且つ洗浄水の流れもスムーズになってサイホンが誘発されやすくなる。 By making the upper curved surface of the front inner surface of the socket channel bulge toward the inside of the socket channel to form a throttle shape, air accumulation in the socket channel is prevented, and a stronger siphon is generated, It will last. Also, the lower curved surface of the front inner surface of the socket channel bulges outward from the socket channel, so that even large dirt can pass through without clogging, and the entire rear inner surface of the socket channel can be By bulging toward the outside of the road, even if filth collides with the flow path, it flows smoothly, and the flow of washing water also becomes smooth, and siphon is easily induced.
本発明によれば、水洗便器のトラップ排水口と外部配水管との間の前後方向の距離(偏心距離)が離れた場合でも排水ソケット内での汚物の詰まりが発生しにくい。したがって、水洗便器を従来よりも後方の壁に近づけ、トイレ空間を広くすることが可能になる。
また本発明に係る排水ソケットは、金型形状を工夫することによって射出成形による一体成形が可能となる
According to the present invention, even when the distance in the front-rear direction (eccentric distance) between the trap drain of the flush toilet and the external water pipe is increased, clogging of filth in the drain socket is unlikely to occur. Therefore, the flush toilet can be brought closer to the rear wall than before, and the toilet space can be widened.
The drain socket according to the present invention can be integrally molded by injection molding by devising the mold shape.
以下に本発明の実施の一例を添付図面に基づいて説明する。図1は本発明に係る排水ソケットを適用した水洗便器の縦断面図、図2は同排水ソケットの正面図、図3は同排水ソケットの側面図、図4は同排水ソケットの平面図、図5は同排水ソケットの下面図、図6は同排水ソケットの縦断面図である。 Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. 1 is a longitudinal sectional view of a flush toilet to which a drain socket according to the present invention is applied, FIG. 2 is a front view of the drain socket, FIG. 3 is a side view of the drain socket, and FIG. 4 is a plan view of the drain socket. 5 is a bottom view of the drain socket, and FIG. 6 is a longitudinal sectional view of the drain socket.
便器本体1はボール部2の上縁部に沿って洗浄水に旋回流を生じさせる案内凹部3を形成し、またボール部2の底部から後方に向かってトラップ流路4を形成し、このトラップ流路4の下流端を便器本体の排出口5とし、床面に配設固定された排水管6と前記排出口5とを本発明に係る排水ソケット10にて接続している。 The toilet body 1 is formed with a guide recess 3 for generating a swirling flow in the washing water along the upper edge of the ball portion 2 and a trap channel 4 is formed from the bottom of the ball portion 2 to the rear. The downstream end of the flow path 4 is a discharge port 5 of the toilet body, and the drain pipe 6 disposed and fixed on the floor surface and the discharge port 5 are connected by a drain socket 10 according to the present invention.
排水ソケット10は左右に便器本体1を固定するための起立部11を形成している。また、排水ソケット10は便器本体の排出口5に連結される流入部12と、前記排水管6に連結される流出部13と、これら流入部12と流出部13との間に設けられるソケット流路14とを備えている。 The drain socket 10 forms standing parts 11 for fixing the toilet body 1 to the left and right. Further, the drain socket 10 includes an inflow portion 12 connected to the outlet 5 of the toilet body, an outflow portion 13 connected to the drain pipe 6, and a socket flow provided between the inflow portion 12 and the outflow portion 13. Road 14 is provided.
図6に示すように、流入部に連続するソケット流路入口15の中心O2は、便器本体1の前後方向を基準として、前記流入部12の中心O1に対して前方に偏心し、また前記流出部13に連続するソケット流路出口16の中心O3は、便器本体1の前後方向を基準として、前記流出部13の中心O4に対して後方に偏心している。 As shown in FIG. 6, the center O2 of the socket flow path inlet 15 that is continuous with the inflow portion is decentered forward with respect to the center O1 of the inflow portion 12 with respect to the front-rear direction of the toilet body 1, and the outflow The center O3 of the socket flow path outlet 16 continuing to the portion 13 is eccentric rearward with respect to the center O4 of the outflow portion 13 with respect to the front-rear direction of the toilet body 1.
また、前記流入部12の下端の後部でソケット流路入口15との境界部には、棚部17を設け、この棚部17に洗浄水を当てることで空気の流入を防止している。また棚部17に係止するように流入部12内には洗浄水滞留部材18を配置している。 In addition, a shelf 17 is provided at the rear of the lower end of the inflow portion 12 at the boundary with the socket channel inlet 15, and the inflow of air is prevented by applying washing water to the shelf 17. Further, a washing water retention member 18 is arranged in the inflow portion 12 so as to be locked to the shelf portion 17.
図8は洗浄水滞留部材18の断面図、図9は洗浄水滞留部材18の平面図である。これらの図に示すように、洗浄水滞留部材18は略筒状をなし、中間に絞り部19を形成し、下部をスカート部20とし、このスカート部20の内側に棚部17への汚物の詰まりを防ぐ突起片21を取り付け、更にスカート部20の一部を切欠22とし、この切欠22を前記棚部17に設けた突起23に係合することで、位置決めを行うようにしている。 FIG. 8 is a cross-sectional view of the cleaning water retention member 18, and FIG. 9 is a plan view of the cleaning water retention member 18. As shown in these drawings, the washing water retention member 18 has a substantially cylindrical shape, forms a throttle portion 19 in the middle, and forms a skirt portion 20 in the lower portion. A projection piece 21 for preventing clogging is attached, and a part of the skirt portion 20 is formed as a notch 22, and the notch 22 is engaged with a projection 23 provided on the shelf portion 17 for positioning.
また図6に戻って、ソケット流路出口13の前部には垂下部24を設け、下方からの空気の侵入を防止してサイホン効果を高めるようにしている。 Returning to FIG. 6, a drooping portion 24 is provided at the front portion of the socket flow path outlet 13 to prevent the intrusion of air from below and enhance the siphon effect.
更に、図7(a)〜(c)に示すように、ソケット流路14の前方内側面は上部曲面14aと下部曲面14bを連続して構成され、上部曲面14aはソケット流路14の内方に向かって膨出している。図7(a)の想像線で示すように上部曲面14aを外側に向かって膨出するか直線とすると、絞り効果がなくなり空気溜まりが形成され、これによりサイホンが途切れてしまうことが起きる。 Further, as shown in FIGS. 7A to 7C, the front inner surface of the socket flow path 14 is formed by continuously connecting an upper curved surface 14 a and a lower curved surface 14 b, and the upper curved surface 14 a is inward of the socket flow path 14. Bulges towards If the upper curved surface 14a bulges outward or is made straight as indicated by the imaginary line in FIG. 7A, the throttling effect is lost and an air pocket is formed, thereby causing the siphon to break.
また、下部曲面14bはソケット流路14の外方に向かって膨出している。このように外方に向かって膨出せしめることで、図7(b)に示すように大き目の汚物であっても詰まることなく通過する。 Further, the lower curved surface 14 b bulges outward from the socket channel 14. By bulging outward in this way, even large filth passes as shown in FIG. 7B without clogging.
更に、ソケット流路14の後方内側面14cは全体がソケット流路14の外方に向かって膨出している。このように後方内側面14cを外方に向かって膨出せしめることで、図7(c)に示すように、汚物が通過する際に内側面14cに衝突してもスムーズに通過することができ、また汚物が通過しない場合でも洗浄水は内側面14cに衝突するような流れを形成するためサイホンが誘発されやすい。 Further, the entire rear inner surface 14 c of the socket channel 14 bulges outward from the socket channel 14. By bulging the rear inner side surface 14c outward in this way, as shown in FIG. 7C, even if the filth passes, it can pass smoothly even if it collides with the inner side surface 14c. In addition, even when no filth passes, the washing water forms a flow that collides with the inner side surface 14c, so that siphon is easily induced.
