  The remote-operated drain plug device composed of the above members is constructed as follows. In the construction procedure described below, construction relating to drainage pipes downstream from the drainage trap 5 is omitted. Moreover, the construction procedure described below is merely an example.

First, the drain plug 1 is attached to the opening formed on the bottom surface of the tank body B, the overflow drain plug 2 is attached to the opening formed on the side surface, and the operation unit 7 is attached to the top surface of the tank body B. At this time, since each member is attached via the packing, all the hot water generated in the tank body B is discharged through the drain plug 1 or the overflow drain plug 2.
Next, the transmission part 8 and the driven part 9 are inserted from the horizontal pipe part 31, and the horizontal pipe part 31 and the horizontal pipe part joint 33 are connected by the C-shaped ring 4. At this time, the driven portion 9 is slidably arranged in the storage portion 32 of the drainage pipe joint 3 in the horizontal direction, and the elevating part 91 is slidable in the tangential direction of the drainage pipe. Moreover, the water stop part 84 of the transmission part 8 is arrange | positioned at the cylindrical part of the horizontal pipe part joint 33, and the packing fitted to the water stop part 84 contact | abuts with the internal peripheral surface of the horizontal pipe part joint 33, and it is in a watertight state. Become.
Next, the drain plug 1 and the drain pipe joint 3 are connected by a nut. At this time, the upper end of the drainage pipe joint 3 is inserted into the lower end of the drainage plug 1, and the central part of the drainage pipe joint 3 and the drainage plug 1 is brought into contact with the tapered part of the upper end of the drainage pipe joint 3 and the tapered part of the lower end of the drainage plug 1. Match.
Finally, the drain trap 5 and the drain pipe joint 3 are connected using the C-shaped ring 4, the bellows pipe 21 is connected to the branch pipe portion 52 of the drain trap 5, and the valve body 6 is inserted from the drain port 11. This completes the construction. At this time, the valve body 6 is arranged so that only the vertical movement is allowed by the above-mentioned detent structure and the inclined surface 65 faces the side of the horizontal pipe portion 31.

  The remote-operated drain plug device of this embodiment constructed according to the above procedure operates as follows.

As shown in FIGS. 6 and 7, when the valve body 6 is in the lowered state, the lever 71 is in a raised state, and the driven portion 9 is retracted to the operation portion 7 side. At this time, as shown in FIG. 7, the elevating part 91 is arranged outside the inner peripheral surface of the drainage pipe, and the elevation part 91 does not protrude into the drainage pipe in plan view. Therefore, the valve body 6 is not supported by the elevating part 91 and is lowered by its own weight.
When the user pushes the operating portion 7 (lever 71) from the lowered state of the valve body 6, the inner wire 83 connected to the lower end of the lever 71 moves inside the outer tube 82 toward the valve body 6 side. Based on the advance, the driven portion 9 connected to the inner wire 83 slides to the left in FIG. At this time, the lifting / lowering portion 91 slides in the horizontal direction and tangential direction of the drainage pipe, and a part of the lifter 91 projects along the inner peripheral surface of the drainage pipe along with the sliding, and moves up and down with the inclined surface 65 of the valve body 6. The inclined surface 92 of the part 91 contacts. By the contact, the horizontal stress applied from the driven portion 9 is converted into the vertical stress, and the upward stress is applied to the valve body 6. When the valve body 6 is lifted by the application of the upward stress, the outer edge of the valve body 6 is supported by the mounting portion 93 formed at the upper end of the inclined surface 92. Therefore, as shown in FIGS. 8 and 9, the valve body 6 rises along the inclined surface 92 to open the drain port 11, and the outer edge of the valve body 6 is supported by the mounting portion 93 so that the valve body 6. The rising state of is maintained.

  Next, when the user raises the operating portion 7 (lever 71) from the raised state of the valve body 6, the inner wire 83 connected to the lower end of the lever 71 moves inside the outer tube 82 toward the operating portion 7 side. The driven portion 9 connected to the inner wire 83 slides to the right in FIG. At this time, all the lifting and lowering portions 91 are disposed outside the drainage pipe in a plan view, and the valve body 6 is lowered by its own weight to close the drainage port 11.

  The flow of hot water (drainage) to the remote-operated drain plug device is as follows.

When the valve body 6 is rising, the packing of the valve body 6 is separated from the drain plug 1 and the drain port 11 is opened. Accordingly, the hot water discharged into the tank body B flows into the drain pipe from the drain port 11 and is further discharged to the drain pipe on the sewage side through the drain plug 1, the drain pipe joint 3, and the drain trap 5. At this time, a part of the waste water flowing in from the tank body B is stored in the storage part 51 of the drain trap 5 to form sealed water.
On the other hand, when the valve body 6 is lowered, the packing of the valve body 6 is in contact with the drain plug 1 and the drain port 11 is closed. Therefore, in this state, hot water can be stored inside the tank body B, but when hot water is stored up to the lower end of the overflow drain plug 2, the hot water to be further stored flows into the overflow drain plug 2. It is discharged into the drain trap 5 through the bellows tube 21.

Although the first embodiment of the present invention is as described above, in the first embodiment, when the valve body 6 is in the lowered state, the elevating part 91 is disposed outside the inner peripheral surface of the drainage pipe, In the plan view, the elevating part 91 does not protrude into the drain pipe. Therefore, when the valve body 6 is in the lowered state, the inner surface of the drainage pipe is smooth in plan view, and is easy to clean and has good design.
On the other hand, when the valve body 6 is raised in the first embodiment, the lifting / lowering portion 91 slides in the horizontal direction of the drainage pipe and the tangential direction of the drainage piping, so that a part of the lifting / lowering portion 91 (mounting) Part 93) protrudes along the inner peripheral surface of the drainage pipe, and the outer edge of the valve body 6 is supported by the protruding part. However, even when the valve body 6 is in the raised state, the protruding width of the lifting / lowering portion 91 is smaller than the radius of the drainage pipe. Therefore, even if the valve body 6 is removed from the raised state, Furthermore, a part of the device does not protrude toward the center of the drainage pipe. Therefore, only a part of the elevating part 91 protruding along the inner peripheral surface of the drainage pipe is visible from the user, and the design is good. Also, unlike conventional remote-operated drain plug devices, there is no member projecting toward the center of the drainage pipe, so no hair is entangled with the device, and the user can clean visible parts. Can be easily performed.

  Below, 2nd embodiment of this invention is described using FIG.10 and FIG.11. In the following embodiments, unless otherwise specified, the same numbers are assigned to the same configurations as those in the first embodiment, and description thereof is omitted.

In the remote-operated drain plug device according to the second embodiment of the present invention shown in FIGS. 10 and 11, the valve body 6 is non-rotatably disposed in the drain pipe, and coincides with the lifting / lowering portion 91 at the lower end. It has an inclined surface 65 having a shape.
The driven part 9 is a ring-shaped member, and an elevating part 91 is formed above it. The driven portion 9 has substantially the same outer diameter as the inner periphery of the drainage pipe joint 3, and can rotate in the drainage pipe as the operation portion 7 is operated. The elevating part 91 is composed of an inclined surface 92 and a placing part 93. The inclined surface 92 is formed with an inclination of about 45 degrees at the end of the driven portion 9 and is continuous with the mounting portion 93 formed of a horizontal plane at the upper end.

  In the remote-operated drain plug device according to the second embodiment, when the operation unit 7 is operated, the driven unit 9 rotates in the horizontal direction as the inner wire 83 advances / retreats, and the inner peripheral surface of the drain pipe Slide along. At this time, the elevating part 91 similarly rotates in the horizontal direction and slides along the inner peripheral surface of the drainage pipe, and the inclined surface 65 of the valve body 6 and the inclined surface 92 of the elevating part 91 abut. As described above, since the valve body 6 is configured to be non-rotatable, the horizontal stress applied from the driven portion 9 is converted into vertical stress by the contact, and the valve body 6 is Thus, upward stress is applied. When the valve body 6 is lifted by the application of the upward stress, the outer edge of the valve body 6 is supported by the mounting portion 93 formed at the upper end of the inclined surface 65.

  In the second embodiment, the elevation part 91 always protrudes inside the drainage pipe in plan view, but the elevation part 91 projects along the inner peripheral surface of the drainage pipe and is the same as in the first embodiment. In addition, the protruding width of the elevating part 91 is smaller than the radius of the drainage pipe. Therefore, when the valve body 6 is removed at the time of cleaning, the user can only see the lifting and lowering portion 91 protruding along the inner peripheral surface of the drainage pipe, which is like a conventional remote-operated drainage plug device. Furthermore, a part of the apparatus does not protrude toward the center of the drainage pipe, and the design is very good.

The present invention is not limited to the shapes of the first embodiment and the second embodiment, and various shape changes may be made without departing from the scope of the invention.
For example, in the second embodiment, the driven portion 9 is disposed inside the drainage pipe joint 3, but a part thereof is disposed outside the drainage pipe joint 3, and a part thereof projects inward. It may be.

  Moreover, in each embodiment, although the raising / lowering part 91 contact | abutted directly to the valve body 6, like the 3rd embodiment shown in FIG.12 and FIG.13, the raising / lowering part 91 is horizontal and the inner peripheral surface of drainage piping. The lifting / lowering portion 91 may abut against the valve body 6 indirectly, for example, by abutting against the ring-shaped member by sliding along the ring-shaped member, and the valve body 6 being pushed up by the ring-shaped member.

In the first embodiment, the driven unit 9 includes the two elevating units 91, but the number thereof may be increased or decreased. For example, as in the fourth embodiment shown in FIG. In this case, since force is applied so that the valve body 6 rotates, it is preferable that the valve body 6 has a detent structure as in the first embodiment. Further, the lifting / lowering portion 91 may be partially or entirely exposed regardless of the rising / lowering state of the valve body 6.
In addition, about the construction state of 4th embodiment, since it is the same as that of FIG. 1 which is the construction state of 1st embodiment, the description is abbreviate | omitted.

Moreover, in each embodiment, although the raising / lowering part 91 was sliding horizontally, in the present invention, the operating direction of the raising / lowering part 91 should just be a direction including a horizontal direction component, such as sliding in the diagonal direction. .
Although the valve body 6 has been lowered due to its own weight, the valve body 6 can be provided in accordance with the operation of the elevating part 91 by providing a spring at an appropriate location or by engaging the elevating part 91 with the valve body 6. However, a structure in which a falling stress other than its own weight is applied may be used.
Moreover, in each embodiment, although the valve body 6 was provided with the inclined surface 65 in the lower end, you may form the said inclined surface 65 in the valve cover 61 lower surface. At this time, the elevating part 91 may be provided at a position below the collar part of the drain plug 1.
