Description

  The present invention relates to a drain plug device provided with a plug lid for opening and closing a drain port of a tank body.

  The drain plug device is provided with a plug lid provided in a drain port of a tank body (for example, a bathtub or a washbasin), and opens and closes the drain port by moving the plug lid up and down.

  As a drain plug device, a drain pipe through which drainage flows through a drain port, a stopper cover, a support shaft arranged in a vertically movable state at the center of the drain pipe, a reciprocating movement, a rotation, etc. It is generally known that includes an operation member that can be displaced by the operation member and a transmission member that transmits a driving force generated by the displacement of the operation member to the support shaft side. Further, the drain plug device includes an operation member such as a push button, and the operation member is a hole formed in the tank body (for example, an installation hole formed in the tank body or a structure around the tank body). And an overflow port for preventing overflow of water from the tank body).

  Furthermore, a pipe body (for example, an overflow pipe or a guide pipe) that connects the drain pipe and the hole may be provided. This pipe body can flow the water which passed the said hole part, and the water which passed the said hole part will be guided to a drain pipe through the said pipe body. Moreover, in this kind of drain plug apparatus, the technique of arrange | positioning a transmission member (inner wire of a release wire) to an overflow pipe | tube can be utilized (for example, refer patent document 1 etc.).

  Moreover, in recent years, it has an annular outer peripheral wall part arranged along the inner peripheral surface of the drain pipe (pipe), and a water passage member that directly or indirectly supports the plug lid, and an outer peripheral wall part in the drain pipe. In addition, a drain plug device has been proposed that includes a support portion (support protrusion) that can move up and down at least a portion that supports the outer peripheral wall portion (see, for example, Patent Document 2). In this technique, an attachment pipe that branches off from the drain pipe is provided, and a stopper-side mechanism portion having a support portion that can be rotated or reciprocated is provided on the attachment pipe. And if the driving force by the displacement of an operation member is transmitted to the stopper lid side mechanism part side via a transmission member, the site | part which supports at least an outer peripheral wall part will move up and down among support parts. As a result, the water passing member and thus the stopper lid moves up and down, and the drainage port is opened and closed.

  By the way, in the said technique, in order to arrange | position the stopper cover side mechanism part, it is necessary to provide the said attachment pipe. For this reason, when the pipe body (overflow pipe, guide pipe, etc.) is provided separately, the structure becomes complicated, which may increase the manufacturing cost.

  This invention is made | formed in view of the said situation, The objective is providing the drain plug apparatus which can fully ensure the water flow capability in a pipe body, aiming at the increase suppression of manufacturing cost. is there.

  In the following, each means suitable for solving the above-described object will be described in terms of items. In addition, the effect specific to the means to respond | corresponds as needed is added.

Means 1. A stopper lid that can be moved up and down to open and close the drain of the tank body;
A displaceable operation member provided in a hole formed in the tank body or a structure in the vicinity thereof,
A drain pipe through which drainage that has passed through the drainage port flows;
The internal space of the drain pipe extends in a branching manner in communication with the internal space of the drain pipe, and the water passing through the hole is guided to the drain pipe through the inside of the drain pipe. Tube
While having an outer peripheral wall portion arranged along the inner peripheral surface of the drain pipe, and a water passage member that directly or indirectly supports the stopper lid,
A support portion that protrudes into the drain pipe and supports the outer peripheral wall portion in a state where at least the drain port is open, and at least a portion that supports the outer peripheral wall portion is configured to be movable up and down with respect to the tank body. A plug lid side mechanism portion comprising:
A transmission member that is disposed in the tubular body and transmits a driving force due to displacement of the operation member to the side of the stopper lid side mechanism portion;
The drain plug device is configured such that when the operation member is displaced, a portion of the support portion that supports the outer peripheral wall portion moves up and down, whereby the plug lid moves up and down and the drain port opens and closes. And
The plug lid side mechanism portion is disposed on the inner periphery of a portion connected to the drain pipe in the pipe body, and has a water passage portion serving as a flow path of water that has passed through the hole portion. Stopper device.

  According to the means 1, the stopper lid side mechanism is disposed on the inner periphery of the tube. Therefore, it is not necessary to provide a mounting pipe or the like for disposing the stopper lid side mechanism on the drain pipe. Thereby, the structure can be simplified and the increase in manufacturing cost can be suppressed. Furthermore, even if the space around the drain pipe is relatively small, the drain plug device can be installed, and the degree of freedom of attachment can be improved.

  On the other hand, when the stopper lid side mechanism is arranged on the inner periphery of the tube, there is a concern that the water passing ability of the tube will be reduced. A water flow portion serving as a flow path is provided. Therefore, it is possible to sufficiently ensure the water passing ability in the pipe body, and to smoothly flow water to the drain pipe side.

  Mean 2. The drain plug device according to means 1, wherein the water passage portion has a shape penetrating the central portion of the stopper lid side mechanism portion.

  According to the said means 2, since the water flow part has the shape which penetrates the center part of the stopper lid side mechanism part, it becomes easier for water to pass through the water flow part. Therefore, it is possible to more reliably ensure a better water flow capacity in the pipe body.

Means 3. The hole is an overflow port formed in the tank body to prevent overflow of water from the tank body,
The drain plug device according to means 1 or 2, wherein the operation member is provided in the overflow port.

  According to the means 3, since the operation member is provided in the overflow port, it is not necessary to separately prepare a hole or the like for providing the operation member. Therefore, it is possible to more effectively suppress an increase in manufacturing cost. Further, since the overflow port and the operation member are present at the same position, cleaning and the like are facilitated, and usability can be improved.

  Furthermore, it is possible to more surely prevent the overflow of water from the tank body as the water passage capacity in the pipe body can be sufficiently secured.

Means 4. The plug lid side mechanism portion has a rotatable annular portion disposed on the drain pipe side and having the water passage portion on the inside thereof, and is relatively immovable along the axial direction with respect to the tube body. Configured,
The support portion has a protruding shape protruding from an end surface on the drain pipe side in the annular portion,
The means 2 or 3 is configured such that the annular portion rotates in accordance with the displacement of the operation member, and at least a portion of the support portion that supports the outer peripheral wall portion moves up and down. The drain plug device described.

  The support portion is configured to be capable of reciprocating along the axial direction of the tubular body, and the portion of the support portion that supports the outer peripheral wall portion is formed into an inclined surface shape that is inclined with respect to the reciprocating movement direction. It is conceivable that the part supporting the outer peripheral wall part in the support part can be moved up and down with the reciprocation. However, in this case, when the support portion is reciprocated, the amount of protrusion of the support portion into the drain pipe varies greatly. Here, in order to support the outer peripheral wall portion more reliably, even when the amount of protrusion of the support portion into the drain pipe becomes the smallest, the support portion protrudes to some extent in the drain pipe. In addition, foreign matters such as dirt and dust contained in the drainage are likely to adhere to the support portion, and hygiene and cleaning properties may be deteriorated. On the other hand, if the amount of protrusion of the support part into the drain pipe is suppressed as much as possible to suppress the adhesion of foreign matter and dirt, the support of the outer peripheral wall part becomes unstable (for example, from the support part to the outer peripheral wall part). There is a risk that the stable operation of the apparatus may be hindered.

  Furthermore, when the support portion is configured to be capable of reciprocating, it may be necessary to lengthen the portion of the tubular body where the stopper lid side mechanism portion is disposed to some extent in order to ensure the movement space of the support portion. Therefore, the place where the drain plug device can be installed is limited, and there is a possibility that the degree of freedom of attachment cannot be improved sufficiently.

  In this regard, according to the above means 4, the stopper lid side mechanism portion is not relatively movable along the axial direction with respect to the tube body, and the annular wall portion is rotated so that the outer peripheral wall portion of the support portion is The part to be supported is configured to move up and down. Therefore, when the part of the support part is moved up and down, the protrusion amount of the support part with respect to the drain pipe can be prevented from greatly fluctuating. Thereby, it is possible to support the outer peripheral wall portion in a stable state while effectively suppressing the adhesion of foreign matters or the like to the support portion. As a result, stable operation of the apparatus can be more reliably achieved while improving hygiene and cleaning properties.

  Moreover, since the stopper lid side mechanism part cannot move relative to the tube body along the axial direction thereof, it is not necessary to make the portion of the tube body where the stopper lid side mechanism portion is disposed long. Accordingly, the degree of freedom of attachment can be sufficiently improved.

  Furthermore, according to the said means 4, it can prevent more reliably that the area (water passage area) of a water flow part increases / decreases with the fluctuation | variation of the position along the rotation direction of a ring part. Therefore, even if the drain outlet is in a closed state or an open state, it is possible to sufficiently ensure the water passing ability in the pipe body.

  In addition, it is preferable to comprise a support part so that it may not reach the center axis | shaft of a drain pipe from a viewpoint of suppressing adhesion of the foreign material etc. with respect to a support part more effectively.

Means 5. The transmission member is a wire-like one configured to be reciprocally movable on the inner periphery of a tubular tube member,
The plug lid side mechanism portion has a cylindrical portion adjacent to the annular portion and immovable relative to the tubular body,
The cylindrical portion includes a curved space portion configured such that the transmission member can be inserted from one end side portion, and the other end portion extends substantially along the rotation direction of the annular portion,
The transmission member is arranged in the curved space portion so that the movement direction is converted into a direction substantially along the rotation direction of the annular portion,
The drain plug device according to claim 4, wherein the annular portion is configured to rotate in accordance with the movement of the transmission member located at the other end portion of the curved space portion.

  The phrase “extends substantially along the rotation direction of the annular portion” is not only in the case of extending in the exact same direction with respect to the rotation direction of the annular portion, but also in the rotation direction of the annular portion. It is intended to include the case of extending in a slightly oblique direction.

  According to the means 5, the transmission member is constituted by a wire-like relatively thin object. Therefore, a larger water passage area in the pipe body can be secured.

  Furthermore, according to the above means 5, the transmission member is disposed in the curved space portion, so that the transmission member is substantially along the rotation direction of the annular portion from the extending direction of the portion disposed in the one end side portion of the curved space portion. The direction of movement is converted to the other direction. Then, the annular portion is rotated by the movement of the transmission member located at the other end portion of the curved space portion, that is, the transmission member that moves in a direction substantially along the rotation direction of the annular portion. Therefore, it is not necessary to use a complicated mechanism in changing the moving direction of the transmission member, and the plug lid side mechanism portion can be downsized. Furthermore, since the part located around the water flow part of the stopper lid side mechanism part such as the cylindrical part or the annular part can be arranged on the outer side (near the inner peripheral surface of the tube), the inner side (center side) It is possible to secure a large water flow area of the water flow section located in (). As a result, the area of the water passing portion (water passing area) can be more easily secured.

  The one end side portion of the curved space portion may extend in the axial direction of the tubular body, may extend in the circumferential direction (tangential direction) of the cylindrical portion, or extends in an oblique direction with respect to this circumferential direction. May be.

It can be said that it is located above an imaginary plane including an axis in a portion corresponding to the one end side portion along the axial direction (longitudinal direction) and a horizontal line orthogonal to the axis and extending in the horizontal direction.

  According to the means 6, the one end side portion of the curved space portion is located above the axis (center axis) of the tubular body. Therefore, if a transmission member is arrange | positioned in a curved space part, a transmission member and a tube member will be arrange | positioned above the internal space of a tubular body as a result. Thereby, it becomes difficult to produce the situation that the water flow in a pipe body will be inhibited by a tube member, and the water flow capacity in a pipe body can be improved more. In addition, it is difficult for foreign matter and dirt to adhere to the tube member, and hygiene can be further improved.

Mean 7 The water flow portion is formed by the inner peripheral surface of the annular portion and the cylindrical portion,
The drain plug device according to means 5 or 6, wherein an inner peripheral surface of the annular portion and an inner peripheral surface of the cylindrical portion are flush with each other.

  The term “level” includes not only the exact level, but also a state where a slight level difference or gap exists (the same applies hereinafter).

  According to the said means 7, water will flow more smoothly from a cylindrical part to a ring part, and it can make the water flow capacity in a pipe body more favorable. In addition, foreign matter and dirt are less likely to adhere to the cylindrical portion and the annular portion, and further superior hygiene can be realized.

A state in which relative movement is impossible along the axial direction can be achieved. Thereby, simplification of an apparatus can be achieved and increase suppression of manufacturing cost can be aimed at more effectively.

  Further, according to the above means 8, the plug lid side mechanism is inserted into the first pipe, the second pipe is connected to the first pipe, and the plug lid is connected by the second pipe and the drain pipe. By setting the side mechanism portion in between, the stopper lid side mechanism portion can be attached to the tube body. Therefore, workability related to installation and maintenance of the apparatus can be improved.

  Means 9. At least below the axis of the tube body, the inner peripheral surface of the second tube portion and the inner peripheral surface of the cylindrical portion are flush with each other, and is dependent on any one of the means 5 to 7 The drain plug device according to means 8.

  According to the means 9, water flows more smoothly from the second pipe part to the cylindrical part, and the water passage capacity in the pipe body can be further improved. Moreover, it becomes difficult for foreign matters and dirt to adhere to the second pipe portion and the cylindrical portion, and the hygiene can be further improved.

Means 10. The drainage pipe has a through hole penetrating from its own internal space to the internal space of the tubular body,
The means for forming the through hole in the drain pipe is flush with the inner peripheral surface of the annular part except for the part corresponding to the moving range of the support part. The drain plug device according to any one of 9.

It becomes the state covered with the part. Therefore, it can prevent more reliably that the waste_water | drain which flows through a drain pipe enters into between a stopper lid side mechanism part and a pipe body. As a result, hygiene can be further improved.

  Moreover, according to the said means 10, adhesion of the foreign material and dirt with respect to the outer periphery of an annular part can be suppressed. Thereby, an annular part can be rotated more smoothly and operativity can be improved.

  Furthermore, water flows more smoothly from the annular portion to the portion where the through hole is formed in the drain pipe, and the water passage capacity in the pipe body can be further improved. Moreover, it becomes difficult for foreign matters and dirt to adhere to the annular portion and the drain pipe, and the hygiene can be further improved.

When the first pipe 432 and the second pipe 433 are connected, the O-ring 49 is the first O-ring 49. The tube portion 432 and the second tube portion 433 are sandwiched. Thereby, the 1st pipe part 432 and the 2nd pipe part 433 are connected watertight, and the leakage of water from both is prevented.

  The connecting pipe 5 is connected to an end portion of the second pipe portion 433 that is located on the opposite side of the first pipe portion 432 (the connecting pipe 5 is not shown in FIGS. 1 and 4). Thereby, the waste water that has passed through the overflow port 104 (flowed into the flange member 21) flows into the second pipe portion 433 and the first pipe portion 432 through the elbow member 22 and the connection pipe 5, and finally the drain pipe. 431 is discharged through. That is, in this embodiment, the elbow member 22, the connecting pipe 5, the first pipe part 432, and the second pipe part 433 guide the wastewater that has flowed in through the overflow port 104 to the drain pipe 431. An overflow pipe 7 is configured. The transmission member 3 is disposed inside the overflow pipe 7.

  As shown in FIG. 1, the drain port device 44 includes a water passage member 441, a hair catcher 442, and a plug lid 443.

  The water passage member 441 is disposed in a state that can move up and down in the drain pipe 431, and has an annular outer peripheral wall portion 441A and a support shaft provided coaxially with the outer peripheral wall portion 441A inside the outer peripheral wall portion 441A. 441B and an arm portion (not shown) that connects the two.

  The outer peripheral wall portion 441A is disposed in the drain pipe 431 along the inner peripheral surface of the drain pipe 431. And the water flow member 441 is supported within the drain pipe 431 by the outer peripheral wall 441 </ b> A being placed on the support 454 described later.

  The support shaft 441 </ b> B has a rod shape extending substantially in the vertical direction, and the upper end of the support shaft 441 </ b> B is attached to the center of the back surface of the stopper lid 443 to support the stopper lid 443. In this embodiment, the stopper lid 443 is directly supported by the water passage member 441. However, the stopper lid 443 may be indirectly supported by the water passage member 441 via some member.

  The hair catcher 442 includes a cylindrical portion through which the support shaft 441B is inserted and a collecting portion that spreads outward from the cylindrical portion. This collection part is for collecting foreign substances such as dust contained in the waste water, and has, for example, a mesh shape. Further, the hair catcher 442 is placed on the inner side of the drain port member 41, that is, in the drainage flow path, by placing the outermost peripheral portion on the tapered portion formed on the inner periphery of the drain port member 41. Yes. In the present embodiment, the hair catcher 442 is movable relative to the support shaft 441B, and is basically configured to continue to be disposed at the same position even if the support shaft 441B is displaced (moves up and down). However, for example, the hair catcher 442 may be configured to move together with the support shaft 441B by fixing the hair catcher 442 to the support shaft 441B.

  The plug lid 443 includes a disk-shaped plug lid main body portion 443A made of resin or the like, and a packing portion 443B attached to the plug lid main body portion 443A.

  The plug lid main body portion 443A is provided substantially coaxially with the drain port member 41, and the packing portion 443B is fitted on the outer peripheral side of the back surface thereof.

  The packing portion 443B is formed in an annular shape from an elastically deformable material (for example, rubber or resin). And when the support part 454 mentioned later moves down, the stopper lid 443 moves down together with the water passing member 441, and the entire outer peripheral portion of the packing part 443B contacts the drain port member 41, so that the drain port 102 is closed. It has come to be. On the other hand, when the support part 454 is moved upward, the stopper lid 443 is moved upward together with the water passage member 441 so that the packing part 443B is separated from the drain port member 41 so that the drain port 102 is opened. It has become.

  In addition, in this embodiment, the drain port device 44 can be removed from the drain pipe 431 at a time by pulling up the stopper lid 443 and the support shaft 441B from the front side of the wash basin 100. And in the state which removed the drain port apparatus 44 from the drain pipe 431, the inside of the drain pipe 431 will be in the state which protruded only the support part 454 slightly. For this reason, it is possible to improve maintenance and cleaning properties.

  The plug lid side mechanism portion 45 has a cylindrical shape as a whole, and is disposed on the inner periphery of a portion (in the present embodiment, the first tube portion 432) connected to the drain pipe 431 in the overflow pipe 7. Further, in the present embodiment, the stopper lid side mechanism portion 45 is arranged on the inner periphery of the first pipe portion 432, and then the stopper tube side mechanism is connected by connecting the second pipe portion 433 to the first pipe portion 432. The part 45 is sandwiched and held between the drain pipe 431 and the second pipe part 433. The stopper lid side mechanism 45 may be sandwiched and held between the pipe portions 432 and 433.

  As shown in FIG. 5, the plug lid side mechanism unit 45 includes a cylindrical part 451, a rotatable annular part 452 provided adjacent to the end face of the cylindrical part 451, the cylindrical part 451 and the annular ring. A case portion 453 that accommodates the portion 452 and a support portion 454 formed integrally with the annular portion 452 are provided.

  The cylindrical portion 451 has a smooth surface shape with an inner circumference having a constant inner diameter along its own axial direction, and has a curved space portion 451A and a mounting projection 451B on the outer circumference, as shown in FIGS. The shape is different.

  The curved space portion 451A has one end side portion (a portion located on the side opposite to the drain pipe 431) extending along the axis CL1 direction of the overflow pipe 7 and the other end side portion (a part located on the drain pipe 431 side). Has a groove shape curved so as to extend along the rotation direction of the annular portion 452. In addition, one end side portion of the curved space portion 451A is opened to the opposite side to the drain pipe 431, and the other end portion of the transmission member 3 is inserted into the curved space portion 451A from this opening. (See FIGS. 1 and 4). In the present embodiment, a space for guiding the movement of the transmission member 3 is formed by the curved space portion 451A and the case portion 453. When the transmission member 3 moves forward with the forward movement of the operation member 24, the other end portion of the transmission member 3 rotates from the direction along the direction of the axis CL <b> 1 of the overflow pipe 7. The moving direction is converted into the direction along

  Note that the direction in which the one end side portion of the curved space portion 451A extends does not have to be exactly the same as the direction of the axis CL1 of the overflow pipe 7, and may extend in the circumferential direction (tangential direction) of the cylindrical portion 451. You may extend in the diagonal direction between this circumferential direction and the axis | shaft CL1 direction. For example, when the second pipe portion 433 extends in the vertical direction and the first pipe portion 432 extends in the horizontal direction so that the overflow pipe 7 is bent at a right angle or a substantially right angle, You may comprise so that the one end side part of 451A of space parts may extend in the circumferential direction (tangential direction) of the cylindrical part 451. FIG. In this case, a portion (second pipe portion) extending in the vertical direction in the overflow pipe 7 is arranged by arranging one end side portion of the curved space portion 451A in a portion (second pipe portion 433) extending in the vertical direction in the overflow pipe 7. 433) can be inserted into the curved space 451A without difficulty (for example, without being excessively bent). Further, the extending direction of the other end portion of the curved space portion 451A does not have to be exactly the same as the rotating direction of the annular portion 452, and may be slightly inclined with respect to the rotating direction.

  Further, in the present embodiment, the one end side portion of the curved space portion 451A is configured to be positioned above the axis CL1 of the overflow pipe 7 (vertically upward in the present embodiment). Thereby, in a state where the transmission member 3 is arranged in the curved space portion 451A, the transmission member 3 and the tube member 6 are arranged above the internal space of the overflow pipe 7.

  The attachment protrusions 451B have a protrusion shape that protrudes outward, and a plurality (two in this embodiment) are provided at equal intervals along the circumferential direction of the cylindrical portion 451.

  In addition, the cylindrical portion 451 is configured so that the inner peripheral surface thereof is flush with the inner peripheral surface of the second pipe portion 433 at least below the axis CL1 of the overflow pipe 7 (FIGS. 1 and FIG. 1). 4). A slight gap or a step may exist between the inner peripheral surface of the cylindrical portion 451 and the inner peripheral surface of the second pipe portion 433.

  The annular portion 452 has an annular shape having a space extending along the circumferential direction of the annular portion 452, and is adjacent to an end portion on the drain pipe 431 side in the cylindrical portion 451 in a state of being coaxial with the cylindrical portion 451. In addition, the annular portion 452 includes a protruding pressed portion 452A disposed on the other end side portion of the curved space portion 451A (see FIG. 6). When the transmission member 3 is moved forward by moving the operation member 24 forward, the pressed portion 452A is pressed by the other end of the transmission member 3, and the annular portion 452 is rotated in a predetermined direction. Is supposed to Then, when the operation shaft 23B is locked by the lock mechanism, the annular portion 452 is locked at the position after the rotation.

  Further, a return spring 452B is disposed in the internal space of the annular portion 452 (see FIG. 1 and not shown in FIG. 4). The return spring 452B urges the annular portion 452 with a force directed in the direction opposite to the predetermined direction. Therefore, when the lock of the operation shaft 23B is released with the forward movement of the operation member 24, the annular portion 452 rotates toward the opposite side to the predetermined direction by the urging force from the return spring 452B. As a result, the annular portion 452 returns to the original position. In the present embodiment, the other end portion of the transmission member 3 is configured to be simply contactable with the pressed portion 452A, but the annular portion 452 and the other end portion of the transmission member 3 may be connected. . That is, the annular portion 452 may be configured to rotate in conjunction with the reciprocating movement of the transmission member 3. In this case, a return spring may be provided in the operating device 2 (for example, the operation side mechanism unit 23), and the transmission member 3 may be moved back by the return spring when the lock is released.

  The annular portion 452 has a constant inner diameter that is the same as the inner diameter of the cylindrical portion 451 along the axial direction thereof. Thereby, the inner peripheral surface of the cylindrical part 451 and the inner peripheral surface of the annular part 452 are flush with each other (see FIGS. 1 and 4). Note that a slight gap or step may exist between the inner peripheral surface of the cylindrical portion 451 and the inner peripheral surface of the annular portion 452.

  Further, a water passage portion 455 extending in the direction of the axis CL1 of the overflow pipe 7 is constituted by the inner peripheral surfaces of the cylindrical portion 451 and the annular portion 452. The water passage portion 455 is a space that becomes a flow path for drainage that has passed through the overflow port 104, and has a shape that penetrates the central portion of the stopper lid side mechanism portion 45 in this embodiment. In addition, in order to ensure sufficient drainage capacity in the water flow portion 455, the cross-sectional area (water flow area) of the water flow portion 455 is at least half of the minimum water flow area in the overflow pipe 7, and in this embodiment, The minimum water flow area is the same.

  The case portion 453 has a cylindrical shape, and includes an annular projecting portion 453A that protrudes radially inward on the inner periphery of the end portion. The case portion 453 has a through portion 453B penetrating from the outer periphery to the inner periphery. And after arrange | positioning the cylindrical part 451 and the annular part 452 coaxially, both are inserted in the case part 453 and the cylindrical protrusion 451B is arrange | positioned with respect to the said penetration part 453B, A cylindrical part 451, an annular ring The part 452 and the case part 453 are integrated.

  Note that the cylindrical portion 451 is not rotatable relative to the case portion 453 by disposing the mounting protrusion 451B in the through portion 453B. Further, although the annular portion 452 is rotatable along the inner peripheral surface of the case portion 453, the annular portion 452 is sandwiched between the overhang portion 453A and the cylindrical portion 451, so that the annular portion 452 extends along the axial direction with respect to the case portion 453. The relative movement is impossible.

  Furthermore, the case portion 453 has a convex portion 453C that protrudes outward at the end opposite to the overhang portion 453A. The convex portion 453 </ b> C is a portion that is disposed in the concave portion 432 </ b> C of the first tube portion 432 in a state where the stopper lid side mechanism portion 45 is disposed on the inner periphery of the first tube portion 432. By disposing the convex portion 453C with respect to the concave portion 432C, the case portion 453 is in a state where it cannot move relative to the overflow pipe 7 (first pipe portion 432). Since the case portion 453 cannot move relative to the overflow pipe 7, the cylindrical portion 451 cannot move relative to the overflow pipe 7 (first pipe portion 432), and the annular portion 452 overflows. The tube 7 (first tube portion 432) cannot move relative to the axial direction.

  The support portion 454 has a protruding shape that protrudes from the end surface of the annular portion 452 on the drain pipe 431 side. When the transmission member 3 moves forward with the forward movement of the operation member 24, the annular portion 452 rotates in the predetermined direction, so that the support portion 454 moves upward. As a result, the outer peripheral wall portion 441A is lifted by the support portion 454, and the drain port 102 is opened. On the other hand, when the operation member 24 is moved forward again in this state, the lock by the lock mechanism is released, and the operation member 24 and the transmission member 3 are moved backward by the urging force from the return spring 452B. The ring portion 452 rotates to the side opposite to the predetermined direction, and the support portion 454 moves downward. As a result, the plug lid 443 (packing portion 443B) contacts the drain port member 41, and the drain port 102 is closed.

  In this embodiment, the outer peripheral wall portion 441A is in contact with the support portion 454 when the drain port 102 is in the open state, but the outer peripheral wall portion 441A is supported when the drain port 102 is in the closed state. It is separated from the part 454. Thereby, when the drain port 102 is closed, the packing part 443B can be reliably brought into contact with the drain port member 41, and good water tightness can be obtained.

  Further, the support portion 454 is relatively short so as not to reach the central axis of the drain pipe 431. Thereby, adhesion of a foreign substance or the like to the support portion 454 can be more effectively suppressed, and hygiene and the like can be improved.

  As described above in detail, according to the present embodiment, the stopper lid side mechanism portion 45 is disposed on the inner periphery of the overflow pipe 7. Therefore, it is not necessary to provide an attachment pipe or the like for disposing the stopper lid side mechanism 45 on the drain pipe 431. Thereby, the structure can be simplified and the increase in manufacturing cost can be suppressed. Furthermore, even if the surrounding space of the drain pipe 431 is relatively small, the drain plug device 1 (drainage side device 4) can be installed, and the degree of attachment freedom can be improved.

  Furthermore, since the operation member 24 is provided in the overflow port 104, it is not necessary to prepare a hole for providing the operation member 24 separately. Therefore, it is possible to more effectively suppress an increase in manufacturing cost. Further, cleaning and the like are facilitated, and usability can be improved.

  In addition, since the stopper lid side mechanism portion 45 cannot move relative to the overflow pipe 7 along the direction of the axis CL1, the portion of the overflow pipe 7 where the stopper lid side mechanism portion 45 is disposed (the first pipe). The part 432) need not be long. Accordingly, the degree of freedom of attachment can be sufficiently improved.

  Further, the stopper lid side mechanism portion 45 is provided with a water passage portion 455 serving as a drainage flow path. Therefore, it is possible to sufficiently ensure the water flow capacity in the overflow pipe 7 and to prevent the overflow of water from the basin 100 more reliably. In particular, in the present embodiment, the water passage portion 455 has a shape that penetrates the central portion of the stopper lid side mechanism portion 45, so that drainage can easily pass through the water passage portion 455. Therefore, it is possible to more reliably ensure a better water flow capacity in the overflow pipe 7.

  In addition, according to the present embodiment, it is more reliably prevented that the area of the water passage portion 455 (water passage area) increases or decreases with the change in the position of the annular portion 452 along the rotation direction. it can. Therefore, even if the drain outlet 102 is in a closed state or an open state, a sufficient water passing capacity in the overflow pipe 7 can be ensured. As a result, the overflow of water from the washbasin 100 can be more reliably prevented.

  Furthermore, the transmission member 3 is comprised by the comparatively thin thing of wire shape. Therefore, even if the transmission member 3 and the tube member 6 are arranged in the overflow pipe 7, a larger water passage area in the overflow pipe 7 can be secured. As a result, it is possible to more reliably prevent water from overflowing from the washbasin 100.

  In addition, the movement direction of the transmission member 3 is changed from the direction along the axis CL1 direction of the overflow pipe 7 to the direction along the rotation direction of the annular portion 452 by being arranged in the curved space portion 451A. . Therefore, it is not necessary to use a complicated mechanism in changing the moving direction of the transmission member 3, and the plug lid side mechanism portion 45 can be downsized. Furthermore, since the part located around the water flow part 455 in the stopper lid side mechanism part 45 such as the cylindrical part 451 and the annular part 452 can be arranged outside (near the inner peripheral surface of the overflow pipe 7), A large water flow area of the water flow portion 455 located on the inner side (center side) can be secured. As a result, the area of the water passage portion 455 (water passage area) can be more easily secured and the water passage capacity in the overflow pipe 7 can be further improved.

  Furthermore, in this embodiment, the stopper lid side mechanism portion 45 is not relatively movable along the axis CL1 direction with respect to the overflow pipe 7, and the support portion 454 is moved up and down by rotating the annular portion 452. Is configured to do. Therefore, when the support part 454 is moved up and down, it is possible to prevent the amount of protrusion of the support part 454 from the drain pipe 431 from fluctuating greatly. Accordingly, it is possible to support the outer peripheral wall portion 441A in a stable state while effectively suppressing the adhesion of foreign matters or the like to the support portion 454. As a result, stable operation of the apparatus can be more reliably achieved while improving hygiene and cleaning properties.

  Further, the one end side portion of the curved space portion 451A is located above the axis CL1 of the overflow pipe 7 (vertically above in the present embodiment), and as a result, the transmission member 3 is located above the internal space of the overflow pipe 7. In addition, the tube member 6 is arranged. Thereby, it becomes difficult to produce the situation where the water flow in the overflow pipe 7 is inhibited by the tube member 6, and the water flow capacity in the overflow pipe 7 can be further enhanced. In addition, it is difficult for foreign matter and dirt to adhere to the tube member 6, and hygiene can be further improved.

  Furthermore, since the inner peripheral surface of the annular portion 452 and the inner peripheral surface of the cylindrical portion 451 are flush with each other, drainage flows more smoothly from the cylindrical portion 451 to the annular portion 452, and the flow through the overflow pipe 7 is made. The water capacity can be made better. In addition, foreign matter and dirt are less likely to adhere to the cylindrical portion 451 and the annular portion 452, and further superior hygiene can be realized.

  In addition, at least below the axis CL1 of the overflow pipe 7, the inner peripheral surface of the second pipe portion 433 and the inner peripheral surface of the cylindrical portion 451 are flush with each other. Therefore, the drainage flows more smoothly from the second pipe part 433 to the cylindrical part 451, and the water passage capacity in the overflow pipe 7 can be further improved. Moreover, it becomes difficult for foreign matters and dirt to adhere to the second pipe portion 433 and the cylindrical portion 451, and the hygiene can be further improved.

  In addition, in the present embodiment, the stopper lid side mechanism portion 45 is connected to the overflow pipe 7 with a relatively simple configuration in which the stopper lid side mechanism portion 45 is sandwiched between the second pipe portion 433 and the drain pipe 431. A state in which relative movement is impossible along the direction of the axis CL1 can be achieved. Thereby, simplification of an apparatus can be achieved and increase suppression of manufacturing cost can be aimed at more effectively.

  Further, after inserting the plug lid side mechanism portion 45 into the first pipe portion 432, the second pipe portion 433 is connected to the first pipe portion 432, and the plug lid side mechanism is connected by the second pipe portion 433 and the drain pipe 431. By setting the state where the portion 45 is sandwiched, the stopper lid side mechanism portion 45 can be attached to the overflow pipe 7. Therefore, workability related to installation and maintenance of the apparatus can be improved.

  Further, in the present embodiment, the region between the outer peripheral surface of the stopper lid side mechanism portion 45 (case portion 453) and the inner peripheral surface of the overflow pipe 7 excluding a portion corresponding to the movement range of the support portion 454, It will be in the state covered with the site | part which forms the through-hole 431B in the drain pipe 431. Therefore, the waste water flowing through the drain pipe 431 can be more reliably prevented from entering between the stopper lid side mechanism portion 45 and the overflow pipe 7. As a result, hygiene can be further improved. In addition, since foreign matters and dirt can be prevented from adhering to the outer periphery of the annular portion 452, the annular portion 452 can be rotated more smoothly, and operability can be improved.

In addition, the portion of the drain pipe 431 where the through hole 431B is formed is flush with the inner peripheral surface of the annular portion 452 except for the portion corresponding to the movement range of the support portion 454. Accordingly, the drainage flows more smoothly from the annular portion 452 to the portion of the drainage pipe 431 where the through hole 431B is formed, and the water passing ability in the overflow pipe 7 can be further improved. In addition, foreign matters and dirt are less likely to adhere to the annular portion 452 and the drain pipe 431, so that hygiene can be further improved.
[Second Embodiment]
Next, the second embodiment will be described focusing on the differences from the first embodiment. In the said 1st Embodiment, although the operating device 2 is provided corresponding to the overflow port 104, in this 2nd Embodiment, as shown in FIG. 8, the operating device 8 is the bathtub 110 as a tank body. Are provided in correspondence with the installation holes 116 as the hole portions formed in. In the second embodiment, the installation hole 116 is formed in a flange portion 115 that protrudes outward from the upper portion of the side wall portion of the bathtub 110. In the second embodiment, the drainage side device 4 is provided corresponding to the drainage port of the bathtub 110.

  The operation device 8 includes a flange member 81, a joint member 82, an operation side mechanism portion 83, and an operation member 84.

  The flange member 81 has a cylindrical shape having a male screw on the outer periphery, and the joint member 82 has a cylindrical shape having a female screw on the inner periphery on the upper end side. Then, with the flange member 81 inserted through the installation hole 116, the flange member 81 and the joint member 82 are connected by screwing the male screw of the flange member 81 with the female screw of the joint member 82, Both are attached to the bathtub 110.

  The operation-side mechanism 83 supports the operation member 84 in a reciprocable manner and transmits a driving force due to the displacement of the operation member 84 to the transmission member 3. The operation member 84 is an operated part operated by the user.

  Furthermore, in the second embodiment, one end of a long cylindrical guide tube 9 extending to the drainage side device 4 side is connected to the outer periphery on the lower end side of the joint member 82. And in the said 1st Embodiment, although the other end part of the connection pipe 5 is connected to the 2nd pipe part 433, in this 2nd Embodiment, not the connection pipe 5, but the other end part of the guide tube 9 Is connected to the second pipe portion 433. Accordingly, the water that has passed through the inside of the installation hole 116 (for example, the inside of the flange member 81) passes through the inside of the joint member 82 and the guide tube 9 and does not leak to the outside. The pipe portion 433) flows down. That is, the guide tube 9 has a function of guiding water to the drainage pipe 431 side while water flows in the inside, like the connection pipe 5 in the first embodiment. In the second embodiment, as a tubular body that guides the water flowing in through the installation hole 116 to the drain pipe 431 by the joint member 82, the guide tube 9, the first pipe portion 432, and the second pipe portion 433. The guide tube 10 is configured.

  As described above, according to the second embodiment, the same operational effects as those of the first embodiment are basically obtained. That is, it is possible to suppress an increase in manufacturing cost and the like, and it is possible to ensure a good water passage capacity in the guide tube 10.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the support portion 454 is configured to rotate and move up and down as the operating member 24 is displaced. What is necessary is just to comprise so that the site | part which supports 441 A of outer peripheral walls may move up and down. Therefore, for example, as shown in FIG. 9, the plug lid side mechanism portion 51 protrudes from the rotation portion 511 that can be rotated by a rotation shaft extending in the horizontal direction and the outer periphery of the rotation portion 511, It may be provided with a rod-like support portion 512 that supports the member 441 (the outer peripheral wall portion 441A). In this case, it is preferable to provide the water flow portion 513 below the rotating portion 511 in terms of achieving good drainage ability and preventing adhesion of foreign matters and the like. In addition, transmission of the driving force from the transmission member 3 to the rotating unit 511 can be performed by, for example, a rack and pinion.

  Further, for example, as shown in FIG. 10, the stopper side mechanism portion 52 has a cylindrical shape having an inclined surface 521 </ b> A that is inclined with respect to the central axis at the distal end surface, and reciprocates along the direction in which the overflow pipe 7 extends. A support portion 521 configured to be movable may be provided. In this case, the water passage member 441 (the outer peripheral wall portion 441A) is supported by the inclined surface 521A, and supports at least the water passage member 441 (the outer peripheral wall portion 441A) of the support portion 521 as the transmission member 3 moves. As the part moves up and down, the water passing member 441 and the plug lid 443 move up and down. Moreover, the water flow part 522 can be comprised by the internal space of the support part 521. FIG.

  (B) In the above embodiment, the water flow portion 455 is formed so as to penetrate the central portion of the stopper lid side mechanism portion 45, but the water flow portion is a drainage flow path that has passed through the overflow port 104. The configuration can be changed as appropriate.

  (C) In the above embodiment, the region between the outer peripheral surface of the stopper lid side mechanism portion 45 (case portion 453) and the inner peripheral surface of the overflow pipe 7 is excluded except for the portion corresponding to the movement range of the support portion 454. The drain pipe 431 is covered with a portion where the through hole 431B is formed, but the area may not be covered with the drain pipe 431. In this case, the stopper lid side mechanism portion 45 can be brought closer to the central axis side of the drain pipe 431, and the support portion 454 can be made shorter.
