Description

本発明は、ストレーナ組立体に関するものである。 The present invention relates to a strainer assembly.

図１に示すストレーナ組立体１が、水回り機器の通水配管に従来から取り付けられている。ストレーナ組立体１は、ネット２とネット２を支持する枠体３とを有する筒状のストレーナ４と、ストレーナ４を長手方向に支持すると共に通水配管１００に形成されたストレーナ挿入口１０１を閉鎖する蓋５とを備えている。
水回り機器の設置工事後に、水回り機器に通水して、通水配管内の塵芥を水回り機器から排出する。前記通水の後、水回り機器への通水を一旦停止し、ストレーナ組立体を通水配管から取り外してストレーナを洗浄し、再度通水配管に取り付ける。 A strainer assembly 1 shown in FIG. 1 is conventionally attached to a water flow pipe of a watering device. The strainer assembly 1 has a cylindrical strainer 4 having a net 2 and a frame 3 that supports the net 2, and supports the strainer 4 in the longitudinal direction and closes the strainer insertion port 101 formed in the water flow pipe 100. The lid 5 is provided.
After installation work of the water supply device, water is passed through the water supply device, and the dust in the water supply pipe is discharged from the water supply device. After the water flow, the water flow to the water supply device is temporarily stopped, the strainer assembly is removed from the water flow pipe, the strainer is washed, and is attached to the water flow pipe again.

設置工事者の不注意や、手違い等により、塵芥排出通水後のストレーナの洗浄が行われない場合がある。ストレーナの洗浄が行われないと、塵芥排出のための通水時にストレーナに溜まった塵芥が残存したまま水回り機器が使用されることになり、ストレーナの目詰まりによる通水不良を起こす可能性がある。
従来のストレーナ組立体は、塵芥排出通水後のストレーナの洗浄が行われたか否かを、外部環境に表示する手段を備えなかったので、塵芥排出通水後のストレーナの洗浄が行われたか否か確認することができなかった。
本発明は上記問題に鑑みてなされたものであり、ネットとネットを支持する枠体とを有する筒状のストレーナと、ストレーナを長手方向に支持すると共に通水配管に形成されたストレーナ挿入口を閉鎖する蓋とを備え、通水配管に取り付けられるストレーナ組立体であって、塵芥排出通水後のストレーナの洗浄が行われたことを外部環境に表示する表示手段を備えたストレーナ組立体を提供することを目的とする。 The strainer may not be washed after draining and draining water due to carelessness of the installer and mistakes. If the strainer is not cleaned, water-circulating equipment will be used with dust remaining in the strainer when water is passed to discharge dust, which may cause water flow failure due to clogging of the strainer. is there.
Since the conventional strainer assembly does not have a means to indicate to the external environment whether or not the strainer has been cleaned after the dust discharge and water flow, whether or not the strainer was cleaned after the dust discharge and water flow I could not confirm.
The present invention has been made in view of the above problems, and includes a cylindrical strainer having a net and a frame that supports the net, and a strainer insertion port formed in the water flow pipe while supporting the strainer in the longitudinal direction. Provided is a strainer assembly that includes a lid that is closed and is attached to a water flow pipe, and has a display means for displaying in the external environment that the strainer has been cleaned after draining and passing water. The purpose is to do.

上記課題を解決するために、本発明においては、ネットとネットを支持する枠体とを有する筒状のストレーナと、ストレーナを長手方向に支持すると共に通水配管に形成されたストレーナ挿入口を閉鎖する蓋とを備え、通水配管に取り付けられるストレーナ組立体であって、ストレーナの枠体には、筒状のストレーナの長手方向一端に近接して配設された第１係止部と、筒状のストレーナの長手方向他端に近接して配設された第２係止部とが形成され、第１係止部と前記一端との間の距離は第２係止部と前記他端との間の距離よりも小であり、蓋には前記第１係止部および第２係止部の何れにも係止可能な係止部が形成されていることを特徴とするストレーナ組立体を提供する。
本発明に係るストレーナ組立体は、水回り機器の設置工事の際に、枠体の第１係止部が蓋の係止部に係止した状態で通水配管に取り付けられる。第１係止部とストレーナの長手方向一端との距離は小なので、水回り機器の設置時にはストレーナの蓋からの突出量は大きい。通水配管には挿入されたストレーナの先端が当接する受け部が形成されており、ストレーナ組立体を通水配管に取り付ける際には、ストレーナの先端が前記受け部に当接するまでストレーナを通水配管に挿入する。前述の如く、水回り機器の設置工事時には、ストレーナの蓋からの突出量は大きいので、ストレーナの通水配管への挿入量は小さく、蓋の通水配管外面からの突出量は大きい。
水回り機器設置工事後の塵芥排出通水後にストレーナ組立体を通水配管から取り外して、ストレーナを洗浄する。洗浄後にストレーナ組立体を通水配管に取り付ける際に、ストレーナを長手方向に逆転させ、枠体の第２係止部を蓋の係止部に係止させる。第２係止部とストレーナの長手方向他端との距離は大なので、ストレーナの蓋からの突出量が小になる。この結果、ストレーナの先端が通水配管に形成されたストレーナ受け部に当接するまでストレーナを通水配管に挿入して、ストレーナ組立体を通水配管に取り付けると、蓋の通水配管外面からの突出量が小になる。
従って、水回り機器の使用時に、ストレーナ組立体の蓋の通水配管外面からの突出量が小であれば、少なくとも塵芥排出通水後にストレーナ組立体を通水配管から取り外したことが分かり、ストレーナの洗浄以外にストレーナを取り外す理由が無いことから、ストレーナの洗浄が行われたことが分かる。 In order to solve the above-mentioned problems, in the present invention, a cylindrical strainer having a net and a frame that supports the net, and the strainer insertion port formed in the water flow pipe are closed while supporting the strainer in the longitudinal direction. A strainer assembly that is attached to the water flow pipe, and is provided on the strainer frame, the first locking portion disposed in the vicinity of one end in the longitudinal direction of the cylindrical strainer, and the cylinder A second locking portion disposed in proximity to the other longitudinal end of the strainer is formed, and the distance between the first locking portion and the one end is the second locking portion and the other end A strainer assembly characterized in that a latching portion that is latched on either the first latching portion or the second latching portion is formed on the lid. provide.
The strainer assembly according to the present invention is attached to the water flow pipe in a state where the first locking portion of the frame is locked to the locking portion of the lid during the installation work of the watering device. Since the distance between the first locking portion and one end in the longitudinal direction of the strainer is small, the amount of protrusion from the strainer lid is large when installing the watering device. The water passage piping is formed with a receiving portion where the tip of the inserted strainer contacts, and when the strainer assembly is attached to the water piping, the strainer is passed through until the tip of the strainer contacts the receiving portion. Insert into the pipe. As described above, since the amount of protrusion from the strainer lid is large during the installation work of the watering device, the amount of insertion of the strainer into the water passage pipe is small, and the amount of protrusion of the lid from the outer surface of the water passage pipe is large.
Remove the strainer assembly from the water pipe after the dust drainage and water flow after installing the water supply equipment, and clean the strainer. When the strainer assembly is attached to the water pipe after cleaning, the strainer is reversed in the longitudinal direction, and the second locking portion of the frame is locked to the locking portion of the lid. Since the distance between the second locking portion and the other end in the longitudinal direction of the strainer is large, the amount of protrusion from the strainer lid is small. As a result, when the strainer is inserted into the water pipe until the end of the strainer comes into contact with the strainer receiving portion formed on the water pipe, and the strainer assembly is attached to the water pipe, The amount of protrusion is small.
Therefore, if the amount of protrusion of the lid of the strainer assembly from the outer surface of the water pipe is small when using the watering device, it is understood that the strainer assembly has been removed from the water pipe after at least the dust discharge water flow. Since there is no reason to remove the strainer other than cleaning, it can be seen that the strainer has been cleaned.

本発明の好ましい態様においては、蓋のストレーナ挿入口に挿入される部位の基部が着色されている。
本発明の好ましい態様においては、蓋のストレーナ挿入口に挿入される部位の基部に着色された環状体が装着されている。
水回り機器の設置工事時には、ストレーナの通水配管への挿入量が小なので、蓋のストレーナ挿入口に挿入される部位の基部は前記挿入口に挿入されず外部環境に暴露される。ストレーナ洗浄後に通水配管に再度取り付けられる際には、ストレーナの通水配管への挿入量が増大するので、蓋のストレーナ挿入口に挿入される部位の基部は前記挿入口に挿入され、前記基部が外部環境から遮断される。従って、前記基部に着色し、或いは前記基部に着色した環状体を装着しておけば、前記着色部或いは前記着色した環状体が視認されないことにより、少なくとも塵芥排出通水後にストレーナ組立体を通水配管から取り外したことが分かり、ストレーナの洗浄以外にストレーナを取り外す理由が無いことから、ストレーナの洗浄が行われたことが分かる。 In the preferable aspect of this invention, the base of the site | part inserted in the strainer insertion port of a lid | cover is colored.
In a preferred embodiment of the present invention, a colored annular body is attached to the base portion of the portion to be inserted into the strainer insertion port of the lid.
At the time of installation work of the water supply device, since the amount of insertion of the strainer into the water passage pipe is small, the base portion of the portion inserted into the strainer insertion port of the lid is not inserted into the insertion port and is exposed to the external environment. When the strainer is attached again to the water flow pipe after washing, the amount of insertion of the strainer into the water flow pipe increases, so that the base of the portion to be inserted into the strainer insertion port of the lid is inserted into the insertion port, and the base Is cut off from the external environment. Therefore, if the base is colored or the colored annular body is attached to the base, the colored part or the colored annular body is not visually recognized. It can be seen that the strainer has been removed because there is no reason to remove the strainer other than the strainer cleaning.

本発明の好ましい態様においては、ストレーナの長手方向一端又は長手方向他端の何れか一方に、目印が形成されている。
ストレーナの長手方向一端又は長手方向他端の何れか一方に、目印が形成されていれば、ストレーナ洗浄後にストレーナを蓋に係止する際に、目印を頼りにしてストレーナを正規方向へ差し向けて蓋に係止させることができる。 In a preferred embodiment of the present invention, a mark is formed on either one of the strainer in one longitudinal direction or the other longitudinal end.
If a mark is formed on one end of the strainer in the longitudinal direction or the other end in the longitudinal direction, when the strainer is locked to the lid after the strainer is washed, the strainer is directed to the normal direction by relying on the mark. It can be locked to the lid.

本発明の実施例に係るストレーナ組立体を説明する。
図２、３に示すように、ストレーナ組立体１１は、円筒形のネット１２とネット１２を支持する枠体１３とを有する円筒状の第１部分ストレーナ１４と、有底円筒状のネット１５とネット１５を支持する枠体１６とを有する円筒状の第２部分ストレーナ１７とを備えている。
枠体１３は円筒状に形成された格子構造部材から成る。ネット１２と枠体１３とはインサート成形により一体成形されている。
枠体１６は円筒状に形成された格子構造部材から成る。ネット１５と枠体１６とは、ネット１５の開口部フランジを枠体１６の一端部に埋め込んだ状態でインサート形成により一体成形されている。
ネット１５の網目寸法は、ネット１２の網目寸法よりも小に設定されている。
第１部分ストレーナ１４と第２部分ストレーナ１７とは、第２部分ストレーナ１７のネット１５の底部を第１部分ストレーナ１４内に挿入させた状態で、長手方向に整列して一体に組付けられ、円筒状のストレーナ１８を形成している。 A strainer assembly according to an embodiment of the present invention will be described.
As shown in FIGS. 2 and 3, the strainer assembly 11 includes a cylindrical first partial strainer 14 having a cylindrical net 12 and a frame 13 that supports the net 12, a bottomed cylindrical net 15, and the like. A cylindrical second partial strainer 17 having a frame 16 that supports the net 15 is provided.
The frame 13 is made of a lattice structure member formed in a cylindrical shape. The net 12 and the frame 13 are integrally formed by insert molding.
The frame 16 is composed of a lattice structure member formed in a cylindrical shape. The net 15 and the frame body 16 are integrally formed by insert formation in a state where the opening flange of the net 15 is embedded in one end portion of the frame body 16.
The mesh size of the net 15 is set smaller than the mesh size of the net 12.
The first partial strainer 14 and the second partial strainer 17 are integrally assembled in the longitudinal direction with the bottom of the net 15 of the second partial strainer 17 being inserted into the first partial strainer 14. A cylindrical strainer 18 is formed.

枠体１３には、一体に組付けられたストレーナ１８の長手方向一端、より具体的には第１部分ストレーナ１４側の長手方向一端に近接して、径方向外方へ差し向けられた第１突起１９が形成されている。複数の第１突起１９が周方向に分散して成形されている
枠体１３には、ストレーナ１８の長手方向他端、より具体的には第２部分ストレーナ１７側の長手方向他端に近接して、径方向外方へ差し向けられた第２突起２０が形成されている。複数の第２突起２０が周方向に分散して成形されている。
第１突起１９とストレーナ１８の長手方向一端との間の距離Ｌ１は、第２突起２０とストレーナ１８の長手方向他端との間の距離Ｌ２よりも小に設定されている。 First, the frame 13 is directed radially outward near one end in the longitudinal direction of the strainer 18 integrally assembled, more specifically, one end in the longitudinal direction on the first partial strainer 14 side. A protrusion 19 is formed. The frame 13 in which the plurality of first protrusions 19 are dispersed and formed in the circumferential direction is adjacent to the other end in the longitudinal direction of the strainer 18, more specifically, the other end in the longitudinal direction on the second partial strainer 17 side. Thus, a second protrusion 20 is formed that is directed outward in the radial direction. A plurality of second protrusions 20 are formed in a distributed manner in the circumferential direction.
A distance L1 between the first protrusion 19 and one end in the longitudinal direction of the strainer 18 is set to be smaller than a distance L2 between the second protrusion 20 and the other end in the longitudinal direction of the strainer 18.

図２に示すように、ストレーナ組立体１１は、蓋２１を備えている。蓋２１は円板部２２と、円板部２２から直立する円筒部２３とを有している。円筒部２３の先端部外周に雄螺子２４が形成されている。円筒部２３の先端部内周に環状段部２５が形成されている。円筒部２３の基部近傍にＯリング２６が装着され、円筒部２３の基部に、赤色等の目立つ色に着色されたＯリング２７が装着されている。 As shown in FIG. 2, the strainer assembly 11 includes a lid 21. The lid 21 has a disc portion 22 and a cylindrical portion 23 that stands upright from the disc portion 22. A male screw 24 is formed on the outer periphery of the tip of the cylindrical portion 23. An annular step 25 is formed on the inner periphery of the tip of the cylindrical portion 23. An O-ring 26 is attached in the vicinity of the base of the cylindrical portion 23, and an O-ring 27 colored in a conspicuous color such as red is attached to the base of the cylindrical portion 23.

図２（ａ）に示すように、ストレーナ組立体１１は、図示しない水回り機器の設置工事の際に、ストレーナ１８の長手方向一端が蓋２１の円筒部２３に嵌入し、枠体１３の第１突起１９が蓋２１の環状段部２５に係止した状態で、円筒部２３を通水配管２００のストレーナ挿入穴２０１に挿入し、雄螺子２４を通水配管内壁に形成された雌螺子２０２に螺合させて、通水配管２００に取り付けられる。円筒部２３とストレーナ挿入穴２０１との間の環状隙間は、Ｏリング２６によりシールされる。ストレーナ挿入穴２０１は蓋の円板部２２によって、通水配管２００の外側から覆われる。
第１係止部１９とストレーナ１８の長手方向一端との距離Ｌ１は小なので、ストレーナ１８の円筒部２３への嵌入量は小であり、挿入量水回り機器の設置工事時にはストレーナ１８の蓋２１からの突出量は大きい。通水配管２００には挿入されたストレーナ１８の先端が当接する円環状の受け部２０３が形成されており、ストレーナ組立体１１を通水配管２００に取り付ける際には、ストレーナ１８の先端が受け部２０３に当接するまでストレーナ１８を通水配管２００に挿入する。前述の如く、水回り機器の設置工事時には、ストレーナ１８の蓋２１からの突出量は大きいので、ストレーナ１８の通水配管２００への挿入量は小さく、蓋の円筒部２３の基部はストレーナ挿入穴２０１に進入しておらず、前記基部に装着された着色Ｏリング２７は、外部環境に暴露されている。従って、着色Ｏリング２７を外側から視認可能である。 As shown in FIG. 2 (a), the strainer assembly 11 has a longitudinal end of the strainer 18 fitted into the cylindrical portion 23 of the lid 21 during installation of a watering device (not shown). With the one projection 19 engaged with the annular step portion 25 of the lid 21, the cylindrical portion 23 is inserted into the strainer insertion hole 201 of the water pipe 200, and the male screw 24 is formed on the inner wall of the water pipe. And is attached to the water flow pipe 200. An annular gap between the cylindrical portion 23 and the strainer insertion hole 201 is sealed by the O-ring 26. The strainer insertion hole 201 is covered from the outside of the water flow pipe 200 by the disc portion 22 of the lid.
Since the distance L1 between the first locking portion 19 and one end in the longitudinal direction of the strainer 18 is small, the amount of insertion of the strainer 18 into the cylindrical portion 23 is small. The amount of protrusion from is large. The water passage pipe 200 is formed with an annular receiving portion 203 with which the tip of the inserted strainer 18 abuts. When the strainer assembly 11 is attached to the water passage 200, the tip of the strainer 18 is the receiving portion. The strainer 18 is inserted into the water pipe 200 until it abuts against the water 203. As described above, since the amount of protrusion of the strainer 18 from the lid 21 is large at the time of installation work of the watering device, the amount of insertion of the strainer 18 into the water flow pipe 200 is small, and the base portion of the cylindrical portion 23 of the lid is the strainer insertion hole. The colored O-ring 27 that has not entered 201 and is attached to the base is exposed to the external environment. Therefore, the colored O-ring 27 is visible from the outside.

水回り機器設置工事後に、水回り機器に通水して、通水配管内の塵芥を水回り機器から排出する。この際、通水は図２（ａ）に白抜き矢印で示す経路に沿って流れる。通水は、円環状の受け部２０３で囲まれた流入口２０４を通り、ストレーナ１８の長手方向他端からストレーナ１８に流入する。通水はネット１５の内部空間へ流入し、ネット１５の底壁を通過してネット１２が形成する円筒空間へ流入し、ネット１２を径方向外方へ通過して、ストレーナ１８から流出する。ネット１５の網目寸法はネット１２の網目寸法より小なので、塵芥はネット１５により捕捉され、ネット１２には付着しない。 After the water supply equipment installation work, water is passed through the water supply equipment, and the dust in the water supply pipe is discharged from the water supply equipment. At this time, water flows along a path indicated by a white arrow in FIG. The water flows through the inflow port 204 surrounded by the annular receiving portion 203 and flows into the strainer 18 from the other end in the longitudinal direction of the strainer 18. The water flows into the inner space of the net 15, passes through the bottom wall of the net 15, flows into the cylindrical space formed by the net 12, passes through the net 12 radially outward, and flows out of the strainer 18. Since the mesh size of the net 15 is smaller than the mesh size of the net 12, dust is captured by the net 15 and does not adhere to the net 12.

塵芥排出通水後にストレーナ組立体１１を通水配管２００から取り外して、ストレーナ１８を蓋２１から取り外して洗浄する。洗浄後にストレーナ組立体１１を通水配管に取り付ける際に、図２（ｂ）に示すように、ストレーナ１８を長手方向に逆転させ、枠体１３の第２突起２０を蓋の環状段部２５に係止させる。第２突起２０とストレーナ１８の長手方向他端との距離Ｌ２は大なので、ストレーナ１８の円筒部２３への嵌入量が大になり、ストレーナ１８の蓋２１からの突出量が小になる。この結果、ストレーナ１８の先端が通水配管２００に形成された受け部２０３に当接するまでストレーナ１８を通水配管２００に挿入して、ストレーナ組立体１１を通水配管２００に取り付けると、蓋の円筒部２３の基部がストレーナ挿入穴２０１に進入し、ひいては前記基部に装着された赤色のＯリング２７がストレーナ挿入穴２０１に進入して、外部環境から遮断される。この結果、着色Ｏリング２７を外側から視認できなくなる。
従って、水回り機器の使用時に、着色Ｏリング２７が視認できなければ、少なくとも塵芥排出通水後にストレーナ組立体１１を通水配管２００から取り外したことが分かり、ストレーナ１８の洗浄以外にストレーナ組立体１１を通水配管２００から取り外す理由が無いことから、ストレーナ１８の洗浄が行われたことが分かる。 After the dust discharge water is passed, the strainer assembly 11 is removed from the water pipe 200, and the strainer 18 is removed from the lid 21 and washed. When the strainer assembly 11 is attached to the water pipe after cleaning, as shown in FIG. 2 (b), the strainer 18 is reversed in the longitudinal direction, and the second protrusion 20 of the frame 13 is moved to the annular step 25 of the lid. Lock. Since the distance L2 between the second protrusion 20 and the other end in the longitudinal direction of the strainer 18 is large, the amount of insertion of the strainer 18 into the cylindrical portion 23 is large, and the amount of protrusion of the strainer 18 from the lid 21 is small. As a result, the strainer 18 is inserted into the water pipe 200 until the tip of the strainer 18 abuts on the receiving portion 203 formed in the water pipe 200, and the strainer assembly 11 is attached to the water pipe 200. The base portion of the cylindrical portion 23 enters the strainer insertion hole 201, and as a result, the red O-ring 27 attached to the base portion enters the strainer insertion hole 201 and is blocked from the external environment. As a result, the colored O-ring 27 cannot be viewed from the outside.
Therefore, if the colored O-ring 27 is not visible when using the watering device, it can be understood that the strainer assembly 11 has been removed from the water pipe 200 after at least dust discharge and water passage. Since there is no reason to remove 11 from the water flow pipe 200, it can be seen that the strainer 18 has been cleaned.

水回り機器の使用時に、通水は図２（ｂ）に白抜き矢印で示す経路に沿って流れる。通水は、円環状の受け部２０３で囲まれた流入口２０４を通り、ストレーナ１８の長手方向一端からストレーナ１８に流入する。通水はネット１２が形成する円筒空間へ流入し、ネット１５を通過することなくネット１２を径方向外方へ通過して、ストレーナ１８から流出する。前述の如く、塵芥排出通水時にネット１２には塵芥は付着しないので、仮にネット１５の洗浄が不十分であったとしても、ストレーナ１８の機能は損なわれない。 At the time of using the watering device, water flows along a path indicated by a white arrow in FIG. The water flows through the inflow port 204 surrounded by the annular receiving portion 203 and flows into the strainer 18 from one end in the longitudinal direction of the strainer 18. The water flows into the cylindrical space formed by the net 12, passes through the net 12 radially outward without passing through the net 15, and flows out of the strainer 18. As described above, since dust does not adhere to the net 12 when the dust is discharged and passed, even if the net 15 is not sufficiently cleaned, the function of the strainer 18 is not impaired.

Ｏリング２７を配設するのに代えて、円筒部２３の基部外面を赤色等の目立つ色に着色しても良い。水回り機器の使用時に、円筒部２３の着色された基部が視認できなければ、少なくとも塵芥排出通水後にストレーナ組立体１１を通水配管２００から取り外したことが分かり、ストレーナ１８の洗浄以外にストレーナ組立体１１を通水配管２００から取り外す理由が無いことから、ストレーナ１８の洗浄が行われたことが分かる。
着色したＯリング２７に代えて、樹脂カラー等の着色した環状体を円筒部２３の基部に装着しても良い。
着色したＯリング２７を配設せず、また円筒部２３の基部を着色しなくても、水回り機器の使用時に、蓋の円板部２２の通水配管２００外面からの突出量に着目して、ストレーナ１８の洗浄の有無を判断することができる。前記突出量が小であれば、少なくとも塵芥排出通水後にストレーナ組立体１１を通水配管２００から取り外したことが分かり、ストレーナ１８の洗浄以外にストレーナ組立体１１を通水配管２００から取り外す理由が無いことから、ストレーナ１８の洗浄が行われたことが分かる。
ストレーナ１８の長手方向一端又は長手方向他端の何れか一方に、目印を形成しても良い。ストレーナ１８の長手方向一端又は長手方向他端の何れか一方に、目印が形成されていれば、洗浄後にストレーナ１８を蓋２１に係止する際に、目印を頼りにしてストレーナ１８を正規方向へ差し向けて蓋２１に係止させることができる。
ストレーナ１８から第２部分ストレーナ１７を除去し、第１部分ストレーナ１４を長手方向に延長して、ストレーナ組立体１１を構成するストレーナとしても良い。 Instead of providing the O-ring 27, the outer surface of the base portion of the cylindrical portion 23 may be colored in a conspicuous color such as red. If the colored base of the cylindrical portion 23 is not visible when the watering device is used, it can be seen that the strainer assembly 11 has been removed from the water pipe 200 after at least dust discharge and water passage. Since there is no reason to remove the assembly 11 from the water pipe 200, it can be seen that the strainer 18 has been cleaned.
Instead of the colored O-ring 27, a colored annular body such as a resin color may be attached to the base of the cylindrical portion 23.
Even if the colored O-ring 27 is not disposed and the base portion of the cylindrical portion 23 is not colored, the amount of protrusion of the lid disk portion 22 from the outer surface of the water pipe 200 is noticed when the watering device is used. Thus, it is possible to determine whether or not the strainer 18 is cleaned. If the amount of protrusion is small, it can be seen that the strainer assembly 11 has been removed from the water pipe 200 after at least dust discharge water flow, and the reason for removing the strainer assembly 11 from the water pipe 200 in addition to cleaning the strainer 18 is as follows. From the absence, it can be seen that the strainer 18 has been cleaned.
A mark may be formed on either the longitudinal end of the strainer 18 or the other longitudinal end. If a mark is formed on one end in the longitudinal direction of the strainer 18 or the other end in the longitudinal direction, when the strainer 18 is locked to the lid 21 after cleaning, the strainer 18 is moved in the normal direction by relying on the mark. The lid 21 can be locked in the direction.
The second partial strainer 17 may be removed from the strainer 18, and the first partial strainer 14 may be extended in the longitudinal direction to form a strainer that constitutes the strainer assembly 11.

本発明に係るストレーナ組立体は、水回り機器の通水配管に広く利用可能である。 The strainer assembly according to the present invention can be widely used for water piping of water-circulating equipment.
