Description

排水套管drain casing

本發明係有關於一種將便器本體之流出口與開設於地板面之排水口連接的排水套管。 The present invention relates to a drainage sleeve connecting the outflow port of the toilet body and the drainage port opened on the floor surface.

在以往之西式便器裝置,以使便器本體(之存水彎)的流出口與開設於地板面之排水口在平面上拉開間隔之方式設置便器本體時,考慮其拉開間隔距離而使用了排水套管(例如參照專利文獻1)。 In the conventional Western-style toilet device, when the toilet body was installed so that the outflow port of the toilet body (the water trap) and the drain opening opened on the floor surface were separated on the plane, the separation distance was considered and used. Drainage jacket (for example, refer to Patent Document 1).

設成突出至此種排水套管之排水口連接部的彎曲部之周圍的凸緣部之平面外形呈大約圓形。例如在專利文獻1之排水套管亦相同,凸緣部中,位於彎曲部之兩側的側凸緣及位於彎曲部之前側的前凸緣從彎曲部突出之尺寸為相同程度。此外,於側凸緣設有螺絲固定用孔,於彎曲部前側則未設螺絲固定用孔。 The planar outline of the flange portion provided to protrude to the periphery of the curved portion of the drain connection portion of the drain sleeve is approximately circular. For example, in the drain sleeve of Patent Document 1, in the flange portion, the side flanges located on both sides of the curved portion and the front flange located on the front side of the curved portion protrude from the curved portion to the same extent. 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 curved portion.

如此儘管未開設螺絲固定用孔,但仍使凸緣部之前凸緣與側凸緣同樣地突出係為了確實地覆蓋直接裝設於排水口且與排水套管本體分開之附插入部地板凸緣之故。又,考慮此種雙重構造,在大幅突出之前凸緣,亦可設螺絲固定用 孔。此外,若設此種地板凸緣,雖可吸收彎曲部側之排出口與地板面之排水口的位置偏離,但亦因此需使前凸緣大幅突出。 In this way, the front flange of the flange portion is protruded in the same way as the side flanges even though the screw fixing holes are not provided, so as to surely cover the floor flange with the insertion portion which is directly installed on the drain outlet and is separated from the drain casing body. the reason. In addition, considering such a dual structure, the flange can also be provided with screws for fixing before it protrudes significantly. hole. In addition, if such a floor flange is provided, the positional deviation of the discharge port on the side of the curved portion and the water discharge port on the floor surface can be absorbed, but the front flange needs to protrude significantly.

不過,使用上述之排水套管時,當然需以便器本體之周壁隱藏排水套管之排水口連接部與排水口之連接部分。因而,必須將便器本體設置成凸緣部之前凸緣也以周壁覆蓋。亦即,若前凸緣之突出的程度大,則必須將便器本體設置成於該前凸緣之前端位置的前方配設周壁之前端部。 However, when using the above-mentioned drain sleeve, of course, the peripheral wall of the appliance body needs to hide the connection part of the drain port of the drain sleeve and the drain port. Therefore, it is necessary to cover the flange with the peripheral wall before the toilet body is provided with the flange portion. That is, if the protruding degree of the front flange is large, the toilet body must be installed so that the front end of the peripheral wall is arranged in front of the front end position of the front flange.

總而言之,前凸緣之突出程度越大,便必須使便器本體設置成與廁所之後壁越大幅拉開間隔,而有便器本體之設置位置的條件、限制嚴格,連改造亦無法因應之虞。 All in all, the greater the protruding degree of the front flange, the greater the distance between the toilet body and the rear wall of the toilet must be set, and the conditions and restrictions on the installation position of the toilet body are strict, and even the modification may not be able to cope with it.

本發明係考慮此種情況而提出,其目的在於提供可緩和便器本體之設置位置的條件、限制之排水套管。 The present invention has been made in consideration of such a situation, and an object thereof is to provide a drainage sleeve which can ease the conditions and restrictions on the installation position of the toilet body.

為達成上述目的,本發明之排水套管係將便器本體之流出口與開設於地板面之排水口連接的排水套管,並包含連接於該流出口之便器連接部、連接於該排水口之排水口連接部、連結該便器連接部、該排水口連接部之間的水平配管部;該排水口連接部具有配設成從該水平配管部之端部延伸的彎曲部、以內部連通該彎曲部之方式延伸成筒狀且裝設於該排水口之排水口插入部、在該彎曲部、該排水口插入部之間的外周面側之交界突出至外側且設置於地板面上之凸緣部;該凸緣部至少具有位於該彎曲部之與該水平配管部延伸的方向直交之方向的兩側且具有螺絲固定用孔之側凸緣、位於該水平配管部之相反側的前凸緣;該前凸緣之突出程度小於該側凸緣之突出程度。 In order to achieve the above-mentioned purpose, the drainage sleeve of the present invention is a drainage sleeve that connects the outflow port of the toilet body with the drain port opened on the floor surface, and includes a toilet connection portion connected to the outflow port, a toilet connection portion connected to the drain port. A drain connection part, a horizontal piping part connecting the toilet connection part, and the drain connection parts; the drain connection part has a curved part arranged to extend from the end of the horizontal piping part, and the curved part is communicated with the inside The junction of the outer peripheral surface side between the curved portion and the drain insertion portion extends into a cylindrical shape and is installed on the drain outlet, and the junction of the outer peripheral surface side between the curved portion and the drain insertion portion protrudes to the outside and is provided on the floor. part; the flange part has at least side flanges located on both sides of the curved part in a direction perpendicular to the direction in which the horizontal piping part extends and has screw fixing holes, and a front flange located on the opposite side of the horizontal piping part ; The protruding degree of the front flange is smaller than the protruding degree of the side flange.

由於本發明之排水套管為上述結構,故可緩和便器本體之設置位置的條件、限制。 Since the drainage sleeve of the present invention has the above-mentioned structure, the conditions and restrictions on the installation position of the toilet body can be eased.

可配設本排水套管20之便器裝置1不限具有圖2所示之機器動作型存水彎12的便器裝置,亦可適用於具有固定型存水彎之便器裝置。若為起碼設於地板面5之排水口7與便器本體10之流出口13在前後方向拉開間隔的便器裝置,便可利用此種排水套管20。 The toilet device 1 that can be equipped with the drain casing 20 is not limited to the toilet device having the machine-operated water trap 12 as shown in FIG. Such a drain sleeve 20 can be used in a toilet device in which at least the drain port 7 provided on the floor surface 5 and the outflow port 13 of the toilet body 10 are spaced apart in the front-rear direction.

接著,就排水套管20之詳細結構及排水套管20與便器裝置1之關係,依據圖1~圖3詳述。 Next, the detailed structure of the drain sleeve 20 and the relationship between the drain sleeve 20 and the toilet device 1 will be described in detail according to FIGS. 1 to 3 .

如上述,排水套管20包含便器連接部21、水平配管部22、排水口連接部23,而本實施形態之排水套管20以可分離成不同於該等各部之劃分的三個構件構 成。具體而言,排水套管20由第1構成材31、第2構成材32、及調整聯結具33三個構件構成。 As described above, the drain bushing 20 includes the toilet connecting portion 21, the horizontal piping portion 22, and the drain port connecting portion 23, but the drain bushing 20 of the present embodiment has a structure of three components that can be separated into three different parts. become. Specifically, the drain jacket 20 is composed of three members: a first structural member 31 , a second structural member 32 , and an adjustment coupling 33 .

如圖1(a)所示,第1構成材31係具有排水入口部21a之便器連接部21、與水平配管部22之便器連接部21側的一部分之筒狀部31a一體化的構件。此外,於第1構成材31之排水入口部21a的下側一體形成有用以將第1構成材31穩定地設置於地板面5之設置台部31c。 As shown in FIG. 1( a ), the first constituent material 31 is a member integrated with the toilet connecting portion 21 of the drain inlet portion 21 a and the cylindrical portion 31 a which is a part of the horizontal piping portion 22 on the toilet connecting portion 21 side. Moreover, the installation base part 31c for stably installing the 1st structural material 31 on the floor surface 5 is integrally formed in the lower side of the drain inlet part 21a of the 1st structural material 31.

第2構成材32係對應連接於水平配管部22之排水口連接部23的構件(參照圖1(b)、(c)),因此,於便器側具有徑大於排水口連接部23之本體筒部的便器側開口部32a。此便器側開口部32a之外面下部形成厚以調整高度。 The second constituent material 32 corresponds to a member connected to the drain port connecting portion 23 of the horizontal piping portion 22 (refer to FIGS. 1(b) and (c) ), and therefore, has a body tube with a larger diameter than the drain port connecting portion 23 on the toilet side. The toilet side opening part 32a of the part. The lower part of the outer surface of the toilet-side opening 32a is thickened to adjust the height.

又,調整聯結具33係用以藉將調整聯結具33自身聯結於第1構成材31與第2構成材32之間而以第1構成材31之筒狀部31a、及調整聯結具33構成水平配管部22之筒狀構件。此外,以於水平配管部22之內底面設有用以排水之排水斜面為理想。 In addition, the adjustment coupling tool 33 is configured by the cylindrical portion 31 a of the first structural member 31 and the adjustment coupling tool 33 by connecting the adjustment coupling member 33 itself between the first structural member 31 and the second structural member 32 . The cylindrical member of the horizontal piping portion 22 . In addition, it is desirable to provide a drainage slope for drainage on the inner bottom surface of the horizontal piping portion 22 .

此調整聯結具33具有大徑部33a與小徑部33b,大徑部33a對第1構成材31之筒狀部31a的排水側開口部31b以外嵌方式連接。又,小徑部33b對第2構成材32之便器側開口部32a以內嵌之方式連接。 This adjustment coupling 33 has a large diameter portion 33a and a small diameter portion 33b, and the large diameter portion 33a is externally connected to the drain side opening 31b of the cylindrical portion 31a of the first structural member 31 . Moreover, the small diameter part 33b is connected to the toilet-side opening part 32a of the 2nd structural material 32 so that it may be fitted inside.

因排水套管20係在前後方向連結存水彎12之呈排水姿勢的位置(便器連接部21之排水入口部21a的位置)與排水口7之構件,故排水套管20之全長需與排水姿勢位置、排水口7位置之間的距離大約一致。為形成此種長度,可以切斷將小徑 部33b調整長度。此外,排水套管20亦可為不使用此種調整聯結具33之結構。舉例而言,可為聯結兩構件(例如第1構成材31與第2構成材32)之結構,亦可為以四個構件(例如第1構成材31、第2構成材32及兩個調整聯結具33)構成之結構。 Since the drain sleeve 20 is a member that connects the position of the water trap 12 in the drain posture (the position of the drain inlet portion 21a of the toilet connection portion 21) and the drain port 7 in the front-rear direction, the entire length of the drain sleeve 20 needs to be matched with the drain port 7. The distance between the posture position and the position of the drain port 7 is approximately the same. To create this length, the small diameter can be cut off The length of the portion 33b is adjusted. In addition, the drainage sleeve 20 can also be a structure without using such an adjustment coupling 33 . For example, it may be a structure in which two members (eg, the first constituent material 31 and the second constituent member 32 ) are connected, or four members (eg, the first constituent member 31 , the second constituent member 32 , and two adjustment members) may be used. The structure formed by the coupling device 33).

第2構成材32所對應之排水口連接部23包含便器側開口部32a、彎曲部24、排水口插入部25、凸緣部26而構成。從便器側開口部32a經由彎曲部24至排水口插入部25,內部連通。 The water outlet connection portion 23 corresponding to the second constituent material 32 includes a toilet-side opening portion 32 a , a curved portion 24 , a water outlet insertion portion 25 , and a flange portion 26 . The inside is communicated from the toilet-side opening portion 32a to the drain port insertion portion 25 via the curved portion 24 .

藉將此排水口插入部25插入、裝設於排水口7,並將後方之便器連接部21的排水入口部21a配設成與便器本體10之流出口13(存水彎箱14之下端開口部)的位置一致,可將排水套管20配設於適當之位置(參照圖1(a)、圖2)。在如此恰當地設置排水套管20之狀態下,凸緣部26之背面抵接地板面5。 By inserting and installing the drain port insertion portion 25 in the drain port 7, the drain inlet portion 21a of the toilet connecting portion 21 at the rear is arranged to be connected with the outflow port 13 of the toilet body 10 (the lower end of the trap box 14 is open). The position of the part) is the same, and the drainage sleeve 20 can be arranged in an appropriate position (refer to FIG. 1(a) and FIG. 2). In a state where the drain sleeve 20 is properly installed in this manner, the back surface of the flange portion 26 abuts on the floor surface 5 .

如圖1(b)所示,凸緣部26具有位於彎曲部24之兩側、亦即與水平配管部22之長向(排水流動方向)直交的方向之兩側的兩個側凸緣26a、位於彎曲部24之前側的前凸緣26b而形成。此外,凸緣部26之後部相當於便器側開口部32a之外面下部。 As shown in FIG. 1( b ), the flange portion 26 has two side flanges 26 a located on both sides of the curved portion 24 , that is, on both sides of the direction perpendicular to the longitudinal direction (the drainage flow direction) of the horizontal piping portion 22 . , the front flange 26b located on the front side of the curved 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.

如圖1(b)所示,側凸緣26a俯視時於彎曲部24之兩側使外形呈彎曲或多角形而突出成翼狀。於此側凸緣26a分別開設有前後排列成大約順著外緣之形狀且以螺絲連接於地板面5之兩個螺絲固定用孔26aa。 As shown in FIG. 1( b ), the side flanges 26a protrude into a wing shape on both sides of the curved portion 24 in a plan view by making the outer shape curved or polygonal. The side flanges 26a are respectively provided with two screw fixing holes 26aa which are arranged in a shape approximately along the outer edge and are connected to the floor surface 5 by screws.

另一方面,前凸緣26b突出成外形呈大約圓弧形。該圓弧之兩端位於側凸緣26a之外緣的內側(兩外緣靠近之方向),且該圓弧位於藉由鈍角狀彎折部26ba與側凸緣26a之前端緣26ab連續的位置。 On the other hand, the front flange 26b protrudes in an approximately circular arc shape. Both ends of the circular arc are located inside the outer edge of the side flange 26a (in the direction in which the two outer edges approach), and the circular arc is located at a position where the obtuse-angled bent portion 26ba is continuous with the front end edge 26ab of the side flange 26a .

總而言之,前凸緣26b係呈由一假想彎曲線27(圖1(b)之二點鏈線)朝後方後退般形成切口的形狀,該假想彎曲線係將側凸緣26a之外緣的前端以不彎折而往前方描繪出與前凸緣26b呈同心圓之圓弧方式彼此連結而成。亦即,側凸緣26a之設有兩個螺絲固定用孔26aa的部位未以延伸至前方之方式形成於前凸緣26b,也未於前凸緣26b設用於以螺絲固定之孔。具體而言,在兩個側凸緣26a各自中之比前凸緣26b突出的部分,開設有螺絲固定用孔26aa。 In short, the front flange 26b is in the shape of a notch formed by retreating rearwardly by an imaginary bending line 27 (two-dot chain line in FIG. They are connected to each other so as to draw an arc concentric with the front flange 26b forward without being bent. That is, the portion of the side flange 26a where the two screw fixing holes 26aa are provided is not formed in the front flange 26b so as to extend to the front, nor is the front flange 26b provided with a screw fixing hole. Specifically, in each of the two side flanges 26a, a portion protruding from the front flange 26b is provided with a screw fixing hole 26aa.

藉使前凸緣26b呈此種形狀,從排水口7之中心X(參照圖1(b))至外緣的尺寸A遠小於從排水口7之中心X至側凸緣26a之外緣的尺寸B(參照圖1(b))。亦即,俯視時之排水套管20的中心線與前凸緣26b之圓弧形外緣交叉的前端位置C位於中心線與假想彎曲線27交叉之前端位置D的後方(參照圖1(b))。 If the front flange 26b has such a shape, the dimension A from the center X (refer to FIG. 1(b)) of the drain port 7 to the outer edge is much smaller than the dimension A from the center X of the drain port 7 to the outer edge of the side flange 26a. Dimension B (refer to Fig. 1(b)). That is, the front end position C where the center line of the drain sleeve 20 intersects with the arcuate outer edge of the front flange 26b in plan view is located behind the front end position D where the center line intersects the virtual bending line 27 (see FIG. 1(b). )).

圖3係比較前端位置C(本排水套管20)與前端位置D(對應前端位置D之排水套管200)的示意縱截面圖。便器裝置1之周壁15需設置成其前端部15a之下端配設於前端位置C、前端位置D之前方。因而,使前端位置C、前端位置D與周壁15的前端部15a之間的距離相同時,前端位置C時之前端部15a比前端位置D時之前端部15a後側。 FIG. 3 is a schematic longitudinal sectional view comparing the front end position C (the present drainage sleeve 20 ) and the front end position D (the drainage sleeve 200 corresponding to the front end position D). The peripheral wall 15 of the toilet device 1 needs to be arranged so that the lower end of the front end portion 15a is arranged in front of the front end position C and the front end position D. Therefore, when the distances between the leading end position C, the leading end position D and the leading end portion 15a of the peripheral wall 15 are the same, the leading end portion 15a at the leading end position C is more rearward than the leading end portion 15a at the leading end position D.

總而言之,如圖1(b)所示藉使前凸緣26b往前方突出之程度小於側凸緣26a之突出程度,可使便器裝置1整體靠近廁所之後壁(圖中未示)。換言之,使排水套 管20之排水口連接部23的凸緣部26呈如圖1(b)之形狀與便器本體10亦即便器裝置1之設置位置的條件、限制減少而增加設置位置之自由度相關。 All in all, as shown in FIG. 1(b), by making the front flange 26b protrude forward less than the side flange 26a, the toilet device 1 as a whole can be close to the rear wall of the toilet (not shown). In other words, make the drain jacket The shape of the flange portion 26 of the water outlet connecting portion 23 of the pipe 20 as shown in FIG.

又,凸緣部26之背面(排水口插入部25側之面)除了設於側凸緣26a之螺絲固定用孔26aa外呈約略平面。因而,若適當地配置排水套管20,凸緣部26大約全體可密合於地板面5。因此,可實現排水套管20之穩定的設置。 Moreover, the back surface of the flange part 26 (surface on the side of the drain insertion part 25) is substantially flat except for the screw fixing hole 26aa provided in the side flange 26a. Therefore, if the drain sleeve 20 is appropriately arranged, the flange portion 26 can be brought into close contact with the floor surface 5 in its entirety. Therefore, stable setting of the drain sleeve 20 can be achieved.

又,由於構造係排水口插入部25內嵌於排水口7,凸緣部26密合於地板面5,故可防止排水套管20之排水口連接部23偏離或傾斜,亦可防止排水之漏出。 In addition, since the structure is that the drain port insertion portion 25 is embedded in the drain port 7, and the flange portion 26 is in close contact with the floor surface 5, the drain port connecting portion 23 of the drain sleeve 20 can be prevented from being deviated or inclined, and the leakage of the drain can be prevented. leakage.

又,由於排水口插入部25一體形成於排水口連接部23作為排水套管20之一部分,故不需要在以往排水套管的安裝上使用的單獨之地板凸緣。因此,需將排水口插入部25形成為對排水口7無尺寸誤差。然而,由於本實施形態係排水口插入部25形成往下方縮窄之錐狀,故即使有些許誤差,亦可對排水口7確切地裝設。 In addition, since the drain insertion portion 25 is integrally formed with the drain connection portion 23 as a part of the drain sleeve 20, a separate floor flange used in the installation of the conventional drain sleeve is not required. Therefore, it is necessary to form the drain port insertion portion 25 so that there is no dimensional error with respect to the drain port 7 . However, in the present embodiment, since the drain port insertion portion 25 is formed in a tapered shape narrowing downward, the drain port 7 can be properly installed even if there is a slight error.

由於本排水套管20為此種構造,故即使不在凸緣部26之前凸緣26b進行螺絲固定亦沒有問題。總而言之,使前凸緣26b之突出程度小於側凸緣26a之突出程度這點無排水套管20之設置強度的問題。 Since the present drain bushing 20 has such a structure, there is no problem even if the flange 26b is not screwed before the flange portion 26 . All in all, the protruding degree of the front flange 26b is made smaller than the protruding degree of the side flange 26a, so that the installation strength of the drain sleeve 20 does not have a problem.

此外,在以上所說明之實施形態中,令凸緣部26之前凸緣26b的形狀呈圓弧形,亦可為其他之形狀,只要突出程度小,亦即只要前端位置C(參照圖1(b))儘量在後方,便可容許各種形狀。舉例而言,亦可使前凸緣26b呈以直線結合圖1(b)之兩個彎折部26ba並切除其前側之形狀。再者,若排水口插入部25在其上下尺 寸內(錐面之範圍內)確實地裝設固定於排水口7,亦可實質上不形成前凸緣26b。亦即,前凸緣26b之突出尺寸亦可為0(零)。此外,排水口插入部25亦可不為錐形,而為一定外徑之管體。 In addition, in the above-described embodiment, the shape of the flange 26b before the flange portion 26 is arc-shaped, but other shapes may be used, as long as the degree of protrusion is small, that is, as long as the front end position C (refer to FIG. 1 ( b)) As far back as possible, various shapes can be tolerated. For example, the front flange 26b can also be formed in a shape in which the two bent portions 26ba of FIG. 1(b) are connected in a straight line and the front side thereof is cut off. Furthermore, if the drain port insertion portion 25 is The front flange 26b may not be substantially formed if it is securely installed and fixed to the drain port 7 within an inch (within the range of the tapered surface). That is, the protruding dimension of the front flange 26b may also be 0 (zero). In addition, the water outlet insertion portion 25 may not be tapered, but may be a pipe body with a certain outer diameter.

又,如圖1(b)等所示,於彎曲部24與凸緣部26之陰角部沿著圓周方向形成有側視時呈三角形之複數的縱向肋條28。以此縱向肋條28可補強凸緣部26而防止破損。特別是在前側,由於前凸緣26b之突出程度小,故可以縱向肋條28謀求強度提高。 Moreover, as shown in FIG.1(b) etc., the internal corner part of the curved part 24 and the flange part 26 is formed with the longitudinal direction rib 28 of a plurality of triangular shape in side view along the circumferential direction. Accordingly, the longitudinal ribs 28 can reinforce the flange portion 26 to prevent breakage. Especially on the front side, since the protruding degree of the front flange 26b is small, the strength of the longitudinal rib 28 can be improved.
