When constructing a remotely operated drain plug device composed of each of the above members on the wash bowl S,
First, the overflow outlet 14 of the operation unit body 6 and the branch pipe part 10 a of the drain connection pipe 10 are connected via the overflow pipe 13. Next, after connecting the end of the inner wire 4b of the release wire 4 to the lower end of the operating body 5, the end of the inner wire 4b on the side of the drain plug body 9 (the end with the rod portion 4c) is connected to the operation unit. The main body 6, the overflow pipe 13, the branch pipe portion 10 a, and the drainage connection pipe 10 are inserted in this order, the release wire 4 is inserted into the overflow pipe 13, and the operating body 5 is housed inside the operation section main body 6. Thereafter, the end of the outer tube 4a of the release wire 4 is connected and fixed to the fixing portion.
Further, the peripheral edge of the operation part mounting hole of the wash bowl S, which is a tank body, is sandwiched between the cover member 12 and the opening peripheral edge of the front face of the operation part main body 6 to fix the cover member 12 and the operation part main body 6 to the wash bowl S. . At this time, the knob 11 of the operating body 5 is projected from the opening 7 of the cover member 12 in the front direction, and the operating body 5 can be slid up and down inside the operating section main body 6 by operating the knob 11. (The operating body 5 has a plane-symmetrical shape in the left-right direction, and the operating body 5 operating in the vertical direction means that the operating body 5 operates in a direction parallel to the plane of symmetry. ). In this embodiment, the overflow outlet 14 is provided directly below the operation section main body 6 and is provided at a position on the symmetry plane of the operating body when construction is completed.
In this state, the release wire 4 on the operation unit 3 side is arranged in the vertical direction together with the moving body 5 that moves up and down, and extends in the front-rear direction (horizontal direction) as in the conventional example. After that, there is no such thing as being bent downward.
Next, after fixing the drain plug body 9 to the mounting hole of the wash bowl S so that the lower surface of the flange 9a contacts the upper surface of the peripheral edge of the mounting hole, the lower end of the drain plug body 9 and the upper end of the drain connection pipe 10 are connected. Furthermore, the lower end of the drainage connection pipe 10 and the underfloor pipe on the sewage side are connected via a trap pipe 17.
Further, the valve member 2 is disposed in the drain plug body 9 from the drain port 1 so that the valve shaft 2b is disposed above the support shaft 8a, and the construction of the remotely operated drain plug device is completed. At this time, the rod portion 4c at the end of the inner wire 4b is disposed at a position directly below the valve shaft 2b.

When using the remote-operated drain plug device attached as described above, first, the drain port 1 is closed, that is, as shown in FIG. 1, the inner wire 4b is retracted toward the operation unit 3 with respect to the outer tube 4a. And since the action body 5 is rising, the rod portion 4c at the opposite end is lowered. At this time, the valve member 2 loses the support of the rod portion 4 c and descends, and the valve body 2 a is in a state of closing the drain port 1. At this time, the positional relationship between the opening 7 of the cover member 12 and the water flow port 15 of the operating body 5 is as shown in FIGS. 2 and 3, with the positions of the water flow port 15 and the opening 7 viewed from the front (FIG. 3). A direction view in the direction of arrow A in the middle).
In the state shown in FIG. 1, since the drain port 1 is closed, the waste water generated by using the wash basin that is a drainer is accumulated inside the wash bowl S that is a tank body, but the cover member 12. When the drainage is accumulated up to the lower end of the opening 7, the drainage in the wash bowl S flows into the operation unit 3 from the lower end of the opening 7, and the opening of the cover member 12 as indicated by the arrow W in FIG. 2. 7, passing through the water flow port 15, the water flow space of the operation unit body 6, and the overflow discharge port 14, and finally sewage from the overflow pipe 13 through the branch pipe part 10 a and the drainage connection pipe 10 and finally from the trap pipe 17. Discharged to the side. For this reason, even if drainage continues in the wash bowl S, the water level of the drainage in the wash bowl S does not rise above a certain level, and the drainage does not overflow from the upper edge of the wash bowl S.
When an operation is applied to the knob portion 11 of the operation unit 3 from this state and the operating body 5 is lowered, the inner wire 4b of the release wire 4 connected to the operating body 5 moves forward to the drain plug side. As a result, as shown in FIGS. 4, 5, and 6, the tip of the rod portion 4 c pushes up the lower end of the valve shaft 2 b of the valve member 2, the valve member 2 as a whole rises, and the valve body 2 a becomes the drain port 1. In this state, the drain port 1 is opened away from the center. In this state, a portion above the knob portion 11 of the operating body 5 serves as a wall to close the opening 7.
In the state shown in FIG. 4, since the drain port 1 is open, drainage generated by the use of the wash basin that is a drainer is directly passed through the drain plug body 9 and the drain connection pipe 10 from the drain port 1. In the end, the water is discharged from the trap pipe 17 to the sewage side, and even if the drainage continues in the wash bowl S, the drainage does not accumulate in the wash bowl S. For this reason, even if the opening 7 is in a closed state, there is no problem that drainage overflows from the toilet bowl.
When an operation is applied to the knob portion 11 of the operation portion 3 from this state to raise the operating body 5, the inner wire 4b moves backward toward the operation portion 3 and the valve member 2 is lowered together with the rod portion 4c. Is closed and returns to the state shown in FIG.
Thereafter, by repeating the same operation, the drain port 1 can be freely opened and closed remotely from the operation unit 3.

In the first embodiment, when the release wire 4 is connected to the operation unit 3, it is connected and arranged only in the vertical direction, and is not arranged in the front-rear direction (horizontal direction). For this reason, the problem that the release wire 4 is suddenly bent downward in the narrow gap space to the wall surface and connected to the drive unit 8 does not occur. With this configuration, there is no occurrence of a buckling problem that the release wire 4 is broken because it is bent with a small bending radius. In addition, the pressure of contact where the inner wire 4b is in contact with the inner surface of the outer tube 4a at the bent portion increases, and the frictional force associated therewith also increases, which hinders the smooth operation of the remote-operated drain plug device. There is no problem.
Moreover, in the said 1st Example, in the closed state of the drain port 1 shown in FIG.1, FIG.2, FIG.3, if it looks at the operation part 3 from the front direction of the operation part 3, the opening part 7 and the water flow hole 15 will be shown. The inside of the operation section main body 6 that performs overflow drainage through the tank can be visually observed, but the user of the tank body usually looks at the inside of the tank body from an obliquely upward direction of the tank body, and in the above-described embodiment, it protrudes. The knob unit 11 of the operation unit 3 does not allow the user of the drainage machine viewing the inside of the tank body from an obliquely upward direction of the tank body to view the inside of the operation unit body 6.
Further, in the opened state of the drain port 1 shown in FIGS. 4, 5, and 6, the opening 7 is closed by the lowered operating body 5, so that the inside of the operation unit main body 6 is opened from the opening 7 of the cover member 12. Is not visible. At this time, the opening 7 of the operation unit 3 is closed, but since the drainage port 1 is opened, the wastewater generated by using the drainage device is discharged from the drainage port 1 and collected in the tank body. Therefore, even if the opening 7 for discharging the overflow drainage is closed, there is no problem in using the drainage device.

The knob portion 11 is a bilaterally symmetric member that is rotatably provided at the upper edge of the opening 7 of the cover member 12, and has a circular arc portion in a side view on the back side. Further, by turning around the upper edge of the opening 7, it moves forward and backward in the operation unit main body 6 through the opening 7, and at the time of this advancement and retraction, an arc portion is formed on the inclined surface 5 a of the operating body 5. Abut. Due to this contact, when the knob portion 11 is pushed inward, the operating body 5 is lowered by the action of the inclined surface 5a. In addition, the knob portion 11 is usually configured to protrude in the tank body direction by a spring member (not shown). In addition, when the operation body 5 is lowered downward as will be described later at the completion of the construction, the lower end of the knob portion 11 is below the upper end of the operation body 5. A user of a wash basin cannot visually observe the inside of the operation unit main body 6 (unless the user places a viewpoint inside the wash bowl S, which is a tank body, and looks up the operation unit 3, it is covered by the knob unit 11. (Because it is not possible to see the upper side of the operation body 5).
In addition, the symmetry plane of the operation body 5 and the symmetry plane of the knob portion 11 are arranged in a positional relationship that coincides when construction is completed (the knob portion 11 is bilaterally symmetrical, so that the barycentric point is arranged on the symmetry plane. For this reason, the barycentric point of the knob member 11 is on the plane of symmetry of the operating body).
The overflow pipe 13 is a member made of a flexible tube that connects the overflow discharge port 14 and the branch pipe portion 10a, and discharges the waste water from the overflow discharge port 14 to the branch pipe portion 10a.
The release wire 4 is a member that transmits an operation applied to the operation unit 3 to the valve member 2, and has a cylindrical outer tube 4a that is flexible in the side surface direction and rigid in the axial direction. And an inner wire 4b which is disposed in the outer tube 4a and is slidably disposed in the outer tube 4a, and has flexibility in the side surface direction and rigidity in the axial direction. One end of the inner wire 4 b of the release wire 4 is disposed at a position directly below the support shaft 8 a of the drive unit 8, and the other end is connected to the operating body 5 of the operation unit 3.
Further, as other members, a trap pipe 17 for connecting to the discharge port of the drain connection pipe 10 is provided.
Further, a wash bowl S of a wash basin that is a tank body in which this remote-operated drain plug device is constructed is a tank body that is open at the top, an attachment hole for attaching a drain plug to the bottom of the tank body, And the operation part attachment hole for attaching the operation part 3 is provided in the vicinity of the upper edge of the tank body.
In the second embodiment, the weight of the valve member 2 and the support shaft 8a is larger than the weight due to the height difference between the operating body 5 and the inner wire 4b.

When constructing a remotely operated drain plug device composed of each of the above members on the wash bowl S,
First, the overflow outlet 14 of the operation unit body 6 and the branch pipe part 10 a of the drain connection pipe 10 are connected via the overflow pipe 13. Next, after connecting the end of the inner wire 4b of the release wire 4 to the lower end of the operation body 5, the end of the inner wire 4b on the drain plug main body 9 side is connected to the operation unit main body 6, the overflow pipe 13, the branch pipe part 10a, The end of the release wire 4 is connected and fixed to the drive unit 8 through the drainage connection pipe 10 in this order.
Thereafter, the operating body 5 is housed in the operation section main body 6 and the drive section 8 is connected and fixed to the fixed section.
Further, the peripheral edge of the operation part mounting hole of the wash bowl S, which is a tank body, is sandwiched between the cover member 12 and the opening peripheral edge of the front face of the operation part main body 6 to fix the cover member 12 and the operation part main body 6 to the wash bowl S. .
At this time, the knob portion 11 of the operation portion main body 6 is in a state of protruding in the front direction from the opening portion 7 of the cover member 12 with the upper edge of the opening portion 7 as the center of rotation, and the knob portion 11. When the push-in operation is performed, the knob portion 11 moves back and forth with the upper edge of the opening 7 as the center of rotation, and the inclined surface 5a comes into contact with or separates from the arc portion provided at the back of the knob portion 11. Thus, the operating body 5 is slidable up and down inside the operation unit main body 6 (the operating body 5 has a plane-symmetrical shape in the left-right direction, and the operating body 5 operating in the up-down direction means that the operating body 5 Means moving along a direction parallel to the plane of symmetry). In this embodiment, the overflow outlet 14 is provided directly below the operation section main body 6 and is provided at a position on the symmetry plane of the operating body when construction is completed.
In this state, the release wire 4 on the operation unit 3 side is arranged in the vertical direction together with the moving body 5 that moves up and down, and extends in the front-rear direction (horizontal direction) as in the conventional example. After that, there is no such thing as being bent downward.
Next, after fixing the drain plug body 9 to the mounting hole of the wash bowl S so that the lower surface of the flange 9a contacts the upper surface of the peripheral edge of the mounting hole, the lower end of the drain plug body 9 and the upper end of the drain connection pipe 10 are connected. Furthermore, the lower end of the drainage connection pipe 10 and the underfloor pipe on the sewage side are connected via a trap pipe 17.
Further, the valve member 2 is disposed in the drain plug body 9 from the drain port 1 so that the valve shaft 2b is disposed above the support shaft 8a, and the construction of the remotely operated drain plug device is completed. At this time, the support shaft 8a of the drive unit 8 is disposed at a position directly below the valve shaft 2b.

When using the remote-operated drain plug device attached as described above, first, the drain port 1 is closed, that is, as shown in FIG. 7, the support shaft 8a of the drive unit 8 is lowered and the inner wire 4b is operated. The moving body 5 is set in a state in which it has moved backward toward the part 3 side. At this time, the valve member 2 loses the support of the support shaft 8a, and is lowered by the valve member 2 and its own weight, so that the valve body 2a closes the drain port 1. Further, at this time, the positions of the water inlet 15 and the opening 7 of the operating body 5 are in a state in which the positions of the water outlet 15 and the opening 7 coincide with each other in a side view as shown in FIG. In this state, since the drain port 1 is closed, the waste water generated by using the drainage device accumulates inside the tank body, but when the drainage collects up to the lower end of the opening 7 of the cover member 12, the opening 7 The waste water in the tank flows into the operation portion 3 from the lower end of the cover and passes through the opening 7 of the cover member 12, the water flow port 15, the operation portion main body 6, and the overflow discharge port 14 as indicated by the arrow W in FIG. 8. Then, it is discharged to the sewage side through the overflow pipe 13, the branch pipe portion 10 a, the drainage connection pipe 10, and finally through the trap pipe 17.
From this state, as shown in FIG. 9, when a push operation is applied in the horizontal direction to the knob portion 11 of the operation portion 3, the arc portion of the back of the knob portion 11 comes into contact with the inclined surface 5a, and the action of the inclined surface 5a The stress of pushing the arc portion of the knob portion 11 in the rearward direction is converted into the stress pushing the operating body 5 downward, and the operating body 5 descends, and the inner wire 4b of the release wire 4 connected to the operating body 5 Advances to the drain plug side. Thereby, the lower end of the support shaft 8a is pushed up by the end portion of the inner wire 4b of the release wire 4, and the support shaft 8a is raised and fixed by the thrust lock mechanism. As a result, as shown in FIG. 10, the tip of the support shaft 8 a pushes up the lower end of the valve shaft 2 b of the valve member 2 to raise the entire valve member 2, and the valve body 2 a is separated from the drain port 1 and the drain port 1. Is opened. In this state, since the support shaft 8a is raised, the inner wire 4b of the release wire 4 reaches the position where the tip of the inner wire 4b contacts the lower end of the support shaft 8a and the weight of the operating body 5 and the own weight of the inner wire 4b itself. Move forward with. For this reason, as shown in FIG. 11, the operation unit 3 moves down to the position where the operating body 5 is lowered and the water inlet 15 cannot be seen from the opening 7, and the knob portion 11 is moved to the inside of the wash bowl S by the spring member. Stop in the protruding state.
In the state shown in FIG. 10, since the drain port 1 is open, drainage generated by the use of the wash basin that is a drainer is directly passed from the drain port 1 to the inside of the drain plug main body 9 and the drain connection pipe 10. In the end, the water is discharged from the trap pipe 17 to the sewage side, and even if the drainage continues in the wash bowl S, the drainage does not accumulate in the wash bowl S.
When a pushing operation is again performed in the horizontal direction on the knob portion 11 of the operation portion 3 from this state, the stress of pushing the arc portion of the knob portion 11 in the rearward direction again causes the operating body 5 to move downward due to the action of the inclined surface 5a. The action body 5 descends and the inner wire 4b of the release wire 4 connected to the action body 5 moves forward to the drain plug side. Thereby, the lower end of the support shaft 8a is pushed up by the end portion of the inner wire 4b of the release wire 4, the lower end of the support shaft 8a is pushed up again by the end portion of the inner wire 4b of the release wire 4, and the fixing of the support shaft 8a is released. The In this case, as described above, in this embodiment, the weight of the valve member 2 and the support shaft 8a is configured to be larger than the weight due to the height difference between the operating body 5 and the inner wire 4b. The entire valve member 2 is lowered together with the shaft 8a, the operating body 5 and the inner wire 4b are retracted (moved to the operation unit 3 side), and the valve body 2a blocks the drain port 1 again as shown in FIG. Return to.
Hereinafter, the drain port 1 can be freely opened and closed remotely by repeating the same operation. In the remote-operated drain plug device of the second embodiment of the present invention, the drain port 1 can be opened and closed by remote operation only by one-way operation of pushing the knob part 11 as described above. From the meaning of “direction”, it is called “one-way remote-controlled drain plug device”.

In the second embodiment, the release wire 4 is arranged only in the up-and-down direction in the operation unit 3 and is not arranged in the front-rear direction (horizontal direction), so the release wire 4 is in a narrow gap space to the wall surface of the room. Thus, there is no problem of being bent downward and connected to the drive unit 8. For this reason, the buckling said that it breaks because the release wire 4 was bent with a small bending radius does not occur. In addition, the pressure of contact where the inner wire 4b is in contact with the inner surface of the outer tube 4a at the bent portion increases, and the frictional force associated therewith also increases, which hinders the smooth operation of the remote-operated drain plug device. There is no problem.
Moreover, in the said 2nd Example, in the closed state of the drain port 1 shown in FIG. 7, FIG. 8, if it looks visually from the front direction of the operation part 3 in the operation part 3, it will pass through the opening part 7 and the water flow hole 15. Although the inside of the operation part main body 6 which performs overflow drainage becomes visible, the user of a tank body usually looks at the inside of a tank body from the diagonally upward direction of a tank body, and the operation part 3 which protruded in the said Example. By the knob portion 11 and the inclined surface 5a projecting forward of the operation body 5, the inside of the operation portion main body 6 can be visually observed from the user of the drainage device viewing the inside of the tank body from an obliquely upward direction of the tank body. Absent.
Further, in the opened state of the drain port 1 shown in FIGS. 10 and 11, since the opening 7 is closed by the lowered operating body 5, the inside of the operation unit main body 6 is visually observed from the opening 7 of the cover member 12. There is nothing. At this time, the opening 7 above the operating body 5 of the operation section 3 is open, but the knob section 11 is disposed in the portion, so that the tank body is tilted by the knob section 11 from an obliquely upward direction of the tank body. The user of the drainage machine that visually observes the inside cannot visually observe the inside of the operation unit main body 6.

Respectively.
The operation unit body 6 accommodates an operating body 5 (described later) in a freely movable manner.
In addition, since the operation unit main body 6 is provided with the overflow discharge port 14 and the wire insertion pipe 18 aligned in a front view of the operation unit main body 6, the operation unit main body 6 can be operated even when the operation body 5 is stored. The body 6 is provided with a drainage space through which the drainage can pass in the lateral direction of the operating body 5, and when construction is completed, as will be described later, the opening 7, the water inlet 15, the drainage space of the operation unit body 6, the overflow The overflow drainage can be discharged from the overflow pipe 13 through the discharge port 14. Further, the wall of the operation section main body 6 opposite to the wire insertion tube 18 is provided with a protruding portion in the side surface direction at least by the width of the wire insertion tube 18. As a result, the reduction of the portion through which the drainage can pass due to the provision of the wire insertion pipe 18 is suppressed, and the performance loss is minimized.
The operating body 5 is a member having a plane-symmetrical shape that is symmetric as a whole and having an inclined surface 5a whose lower end is connected to the inner wire 4b and whose upper and lower sides are wider in the lower part.
Further, a water inlet 15 is provided below the inclined surface 5a for passing the drainage.
The knob portion 11 is a bilaterally symmetric member that is rotatably provided at the upper edge of the opening 7 of the cover member 12, and has a circular arc portion in a side view on the back side. Further, by turning around the upper edge of the opening 7, it moves forward and backward in the operation unit main body 6 through the opening 7, and at the time of this advancement and retraction, an arc portion is formed on the inclined surface 5 a of the operating body 5. Abut. Due to this contact, when the knob portion 11 is pushed inward, the operating body 5 is lowered by the action of the inclined surface 5a. In addition, the knob portion 11 is usually configured to protrude in the tank body direction by a spring member (not shown). In addition, when the operation body 5 is lowered downward as will be described later at the completion of the construction, the lower end of the knob portion 11 is below the upper end of the operation body 5. A user of a wash basin cannot visually observe the inside of the operation unit main body 6 (unless the user places a viewpoint inside the wash bowl S, which is a tank body, and looks up the operation unit 3, it is covered by the knob unit 11. (Because it is not possible to see the upper side of the operation body 5).
In addition, the symmetry plane of the operation body 5 and the symmetry plane of the knob portion 11 are arranged in a positional relationship that coincides when construction is completed (the knob portion 11 is bilaterally symmetrical, so that the barycentric point is arranged on the symmetry plane. For this reason, the barycentric point of the knob member 11 is on the plane of symmetry of the operating body).
The overflow pipe 13 is a member made of a flexible tube that connects the overflow discharge port 14 and the branch pipe portion 10a, and discharges the waste water from the overflow discharge port 14 to the branch pipe portion 10a.
The release wire 4 is a member that transmits an operation applied to the operation unit 3 to the valve member 2, and has a cylindrical outer tube 4a that is flexible in the side surface direction and rigid in the axial direction. And an inner wire 4b which is disposed in the outer tube 4a and is slidably disposed in the outer tube 4a, and has flexibility in the side surface direction and rigidity in the axial direction. One end of the inner wire 4 b of the release wire 4 is disposed at a position directly below the support shaft 8 a of the drive unit 8, and the other end is connected to the operating body 5 of the operation unit 3.
In the first and second embodiments, the release wire 4 is disposed in the overflow pipe 13. In the third embodiment, the release wire 4 is disposed outside the pipe via the wire insertion pipe 18. Then, it connects with the drive part 8 again through the wire connection pipe | tube 19 of the drainage connection pipe | tube 10 bottom face.
Further, as other members, a trap pipe 17 for connecting to the discharge port of the drain connection pipe 10 is provided.
Further, a wash bowl S of a wash basin that is a tank body in which this remote-operated drain plug device is constructed is a tank body that is open at the top, an attachment hole for attaching a drain plug to the bottom of the tank body, And the operation part attachment hole for attaching the operation part 3 is provided in the vicinity of the upper edge of the tank body.
In the third embodiment, the weight of the valve member 2 and the support shaft 8a is larger than the weight due to the height difference between the operating body 5 and the inner wire 4b.
Further, the peripheral edge of the operation part mounting hole of the wash bowl S, which is a tank body, is sandwiched between the cover member 12 and the opening peripheral edge of the front face of the operation part main body 6 to fix the cover member 12 and the operation part main body 6 to the wash bowl S. .
At this time, the knob portion 11 of the operation portion main body 6 is in a state of protruding in the front direction from the opening portion 7 of the cover member 12 with the upper edge of the opening portion 7 as the center of rotation, and the knob portion 11. When the push-in operation is performed, the knob portion 11 moves back and forth with the upper edge of the opening 7 as the center of rotation, and the inclined surface 5a comes into contact with or separates from the arc portion provided at the back of the knob portion 11. Thus, the operating body 5 is slidable up and down inside the operation unit main body 6 (the operating body 5 has a plane-symmetrical shape in the left-right direction, and the operating body 5 operating in the up-down direction means that the operating body 5 Means moving along a direction parallel to the plane of symmetry).
In this third embodiment, as described in the description of the operation section main body 6 and as shown in FIG. 12, the overflow outlet 14 and the wire insertion pipe 18 are arranged side by side in the front direction of the operation section main body 6. Since the operating body 5 provided in a state and configured symmetrically is disposed above the wire sweep pipe 18 at the time of completion of construction, the overflow outlet 14 is connected to the operating body 5 at the time of completion of construction. It is provided at a position other than the symmetry plane.

When constructing a remotely operated drain plug device composed of each of the above members on the wash bowl S,
First, the overflow outlet 14 of the operation unit body 6 and the branch pipe part 10 a of the drain connection pipe 10 are connected via the overflow pipe 13. Next, the end of the inner wire 4 b of the release wire 4 is connected to the lower end of the operating body 5, and then the end of the inner wire 4 b on the drain plug body 9 side is connected to the drainage flow from the operation section body 6 through the wire insertion pipe 18. After taking it out of the road, it is again inserted into the drainage connection pipe 10 through the wire connection pipe 19, and finally the end of the release wire 4 is connected and fixed to the drive unit 8. In addition, the insertion part of the wire insertion pipe | tube 18, the wire connection pipe | tube 19, and the release wire 4 is constructed watertight using packing etc., and it is comprised so that drainage may not leak outside from a drainage flow path. .
Thereafter, the operating body 5 is housed in the operation section main body 6 and the drive section 8 is connected and fixed to the fixed section.
Further, the peripheral edge of the operation part mounting hole of the wash bowl S, which is a tank body, is sandwiched between the cover member 12 and the opening peripheral edge of the front face of the operation part main body 6 to fix the cover member 12 and the operation part main body 6 to the wash bowl S. .
At this time, the knob portion 11 of the operation portion main body 6 is in a state of protruding in the front direction from the opening portion 7 of the cover member 12 with the upper edge of the opening portion 7 as the center of rotation, and the knob portion 11. When the push-in operation is performed, the knob portion 11 moves back and forth with the upper edge of the opening 7 as the center of rotation, and the inclined surface 5a comes into contact with or separates from the arc portion provided at the back of the knob portion 11. Thus, the operation body 5 is slidable up and down within the operation unit main body 6.
In this state, the release wire 4 on the operation unit 3 side is arranged in the vertical direction together with the moving body 5 that moves up and down, and extends in the front-rear direction (horizontal direction) as in the conventional example. After that, there is no such thing as being bent downward.
Next, after fixing the drain plug body 9 to the mounting hole of the wash bowl S so that the lower surface of the flange 9a contacts the upper surface of the peripheral edge of the mounting hole, the lower end of the drain plug body 9 and the upper end of the drain connection pipe 10 are connected. Furthermore, the lower end of the drainage connection pipe 10 and the underfloor pipe on the sewage side are connected via a trap pipe 17.
Further, the valve member 2 is disposed in the drain plug body 9 from the drain port 1 so that the valve shaft 2b is disposed above the support shaft 8a, and the construction of the remotely operated drain plug device is completed. At this time, the support shaft 8a of the drive unit 8 is disposed at a position directly below the valve shaft 2b.

When using the remote-operated drain plug device attached as described above, the drain port 1 is first closed. At this time, the valve member 2 loses the support of the support shaft 8a, and is lowered by the valve member 2 and its own weight, so that the valve body 2a closes the drain port 1. Further, at this time, the positions of the water inlet 15 and the opening 7 of the operating body 5 are in a state in which the positions of the water outlet 15 and the opening 7 coincide with each other in a side view as shown in FIG. In this state, since the drain port 1 is closed, the waste water generated by using the drainage device accumulates inside the tank body, but when the drainage collects up to the lower end of the opening 7 of the cover member 12, the opening 7 The drainage in the tank flows into the operation portion 3 from the lower end of the tube, passes through the opening 7 of the cover member 12, the operation portion main body 6, and the overflow discharge port 14, and enters the overflow pipe 13, the branch pipe portion 10a, and the drainage connection pipe 10 inside. And finally discharged to the sewage side via the trap pipe 17.
When a push operation is applied in the horizontal direction to the knob portion 11 of the operation portion 3 from this state, the arc portion of the back of the knob portion 11 abuts on the inclined surface 5a, and the action of the inclined surface 5a causes the rear portion of the arc portion of the knob portion 11 to come into contact. The stress of pushing in the direction is converted into the stress pushing the operating body 5 downward, the operating body 5 descends, and the inner wire 4b of the release wire 4 connected to the operating body 5 moves forward to the drain plug side. Thereby, the lower end of the support shaft 8a is pushed up by the end portion of the inner wire 4b of the release wire 4, and the support shaft 8a is raised and fixed by the thrust lock mechanism. As a result, as shown in FIG. 13, the tip of the support shaft 8 a pushes up the lower end of the valve shaft 2 b of the valve member 2 to raise the entire valve member 2, and the valve body 2 a is separated from the drain port 1 and the drain port 1. Is opened. In this state, since the support shaft 8a is raised, the inner wire 4b of the release wire 4 reaches the position where the tip of the inner wire 4b contacts the lower end of the support shaft 8a and the weight of the operating body 5 and the own weight of the inner wire 4b itself. Move forward with. At this time, the knob portion 11 stops in a state where the knob portion 11 protrudes to the inside of the wash bowl S by the spring member.
In the state shown in FIG. 13, since the drain port 1 is open, drainage generated by the use of the wash basin that is a drainer is directly passed through the drain plug body 9 and the drain connection pipe 10 from the drain port 1. In the end, the water is discharged from the trap pipe 17 to the sewage side, and even if the drainage continues in the wash bowl S, the drainage does not accumulate in the wash bowl S.
When a pushing operation is again performed in the horizontal direction on the knob portion 11 of the operation portion 3 from this state, the stress of pushing the arc portion of the knob portion 11 in the rearward direction again causes the operating body 5 to move downward due to the action of the inclined surface 5a. The action body 5 descends and the inner wire 4b of the release wire 4 connected to the action body 5 moves forward to the drain plug side. Thereby, the lower end of the support shaft 8a is pushed up by the end portion of the inner wire 4b of the release wire 4, the lower end of the support shaft 8a is pushed up again by the end portion of the inner wire 4b of the release wire 4, and the fixing of the support shaft 8a is released. The In this case, as described above, in this embodiment, the weight of the valve member 2 and the support shaft 8a is configured to be larger than the weight due to the height difference between the operating body 5 and the inner wire 4b. The entire valve member 2 is lowered together with the shaft 8a, the operating body 5 and the inner wire 4b are retracted (moved toward the operation unit 3), and the valve body 2a returns to the state where the drain port 1 is closed again.
Hereinafter, the drain port 1 can be freely opened and closed remotely by repeating the same operation.

In the third embodiment, the release wire 4 is arranged only in the up-and-down direction in the operation unit 3 and is not arranged in the front-rear direction (horizontal direction), so the release wire 4 is in a narrow gap space to the wall surface of the room. Thus, there is no problem of being bent downward and connected to the drive unit 8. For this reason, the buckling said that it breaks because the release wire 4 was bent with a small bending radius does not occur. In addition, the pressure of contact where the inner wire 4b is in contact with the inner surface of the outer tube 4a at the bent portion increases, and the frictional force associated therewith also increases, which hinders the smooth operation of the remote-operated drain plug device. There is no problem.
Moreover, in the said 3rd Example, since the knob part 11 is arrange | positioned in the position which covers diagonally upward of the opening part 7, it is operated from the user of the drainage device which looks at the inside of a tank body from the diagonally upward direction of a tank body. It is not impossible to visually observe the inside of the main part 6 if, for example, the viewpoint is intentionally lowered, but it is almost impossible as long as the drainage device is normally used.

  The embodiments of the present invention are as described above, but the present invention is not limited to the above-described embodiments, and can be freely changed without departing from the scope of the present invention. For example, in the first embodiment and the second embodiment, the water outlet 15 is provided for allowing the operation body 5 to pass the overflow drainage, but the present invention is not limited to the above embodiment, For example, when the inner wire 4b moves forward to the drain plug side, the valve body 2a is configured to descend, and the waste water accumulated in the tank body is discharged through the opening 7 minutes above the lowered operation body 5. You can configure it.

  Further, in the first embodiment, the water inlet 15 is provided only below the operating body 5, but the present invention is not necessarily limited to the above embodiment, and it passes through both above and below the operating body 5. A water port 15 may be provided so that overflow drainage can be performed from the opening 7 regardless of whether the drain port 1 is opened or closed. If it does in this way, even if the drain port 1 is opened, the inside of the operation unit main body 6 can be visually observed, and the design is deteriorated. However, when the drain port 1 is blocked due to a large amount of dust, the opening portion The waste water in the tank can be discharged via 7.

In the second embodiment, the operating body 5 is lowered when the drain port 1 is opened and is raised when the drain port 1 is closed, but the present invention is not necessarily limited to the above embodiment. Except for a state in which a return spring is provided to urge the inner wire 4b of the release wire 4 toward the operation portion 3 and the knob portion 11 is pushed in (the state shown in FIG. 9), the operating body 5 is raised as shown in FIG. You may comprise so that it may do. In this case, like the paragraph 0029, the design is deteriorated, but when the drain port 1 is blocked due to a large amount of dust or the like, the waste water in the tank can be discharged through the opening 7.
In the second embodiment, the water outlet 15 is provided for allowing the operation body 5 to pass the overflow drainage. However, the present invention is not limited to the above embodiment, and the inner wire 4b is, for example, a drain plug. The valve body 2a may be configured to descend when it moves forward, and the waste water accumulated in the tank body may be discharged through the opening 7 above the lowered operation body 5.

  Moreover, in each said Example, although this invention is employ | adopted as the wash bowl S of a washstand, it can be employ | adopted as various tank bodies provided with the drain outlet 1, such as a washstand, a bathtub, and a sink.
