In addition, the casing 65 is provided with a collection portion 66 at the lower end. The collection part 66 is arrange | positioned at the inflow port 82 at the time of completion of construction, as shown in FIG. 6, and prevents the refuse and toy in a hot water being discharged from the overflow port 21. As shown in FIG.

The lock mechanism 7 is a mechanism called a thrust lock mechanism that holds the state of the valve member 4 that has been raised with the operation of the operation unit 8. The lock mechanism 7 is composed of the casing 65 and a rotary gear 71 disposed inside the casing 65, a lock shaft 72, and a spring.
As shown in FIG. 2 etc., the lock shaft 72 is disposed at the center of the casing 65, penetrates the upper surface of the casing 65, and bifurcates from the middle to the upper end. The lower portion 63 of the guiding portion is disposed between the bifurcated portions of the lock shaft 72, so that the end of the transmission member 5 is disposed between the bifurcated portions along the lock shaft 72. A cap-like wire retainer 73 is attached to the upper end of the lock shaft 72, and the end of the exposed inner wire 54 is fixed, and the inner wire 54 is configured to interlock with the lock shaft 72. There is. The lock shaft 72 is arranged to be able to move up and down in the casing 65, and the rotary gear 71 is mounted rotatably and immovably in the vertical direction with respect to the lock shaft 72. The lock mechanism 7 can hold the lowered state of the lock shaft 72 by meshing of the rotary gear 71 and the fixed gear when the lock shaft 72 is lowered, and when the lock mechanism 72 is lowered again, The engagement of the fixed gear is released, and the lock shaft 72 can be raised by the elasticity of the spring.
The lock mechanism 7 is disposed below the actuating portion 81, and the upper end of the lock shaft 72 is in contact with the back surface of the actuating portion 81 via the wire retainer 73. Accordingly, the lock shaft 72 is also moved up and down in accordance with the up and down movement of the operating portion 81. Further, since the axial direction of the lock shaft 72 is vertical, the axial direction of the lock shaft 72 and the displacement direction of the actuating portion 81 and the end portion of the inner wire 54 fixed to the lock shaft 72 The axial direction is substantially parallel.

  As shown in FIGS. 6 and 7, the operation portion 8 is substantially circular in a front view, is attached to the flange member 2, and protrudes toward the inside of the tank body B. The operating unit 8 also includes an operating unit 81 and a positioning member 9.

As shown in FIG. 2 and FIG. 10, the actuating portion 81 is a box whose bottom and back (right side in FIG. 1) are open, and the guide portion 91 of the positioning member 9 is disposed on both sides in front view ing. Further, as shown in FIG. 7, the actuating portion 81 is displaceable only in the vertical direction with respect to the tank body B, and when the valve member 4 is in the raised state, the operating portion 8 has a substantially circular front view, When the valve member 4 is in the lowered state, the actuating portion 81 protrudes below the determining member 81. In addition, the actuating portion 81 is in contact with the lock shaft 72 and the inner wire 54 via the wire retainer 73. Further, the lock mechanism 7 is housed and disposed inside the actuating portion 81.
Here, as described above, the operating portion 81 is a box whose bottom and back are open, but when the construction is completed, the positioning member 9 is disposed on the back and side of the operating portion 81, the bottom Only is open. At this time, the open bottom surface functions as the inflow port 82 and a drainage channel communicating with the overflow port 21 is formed. In addition, although the drainage flow path continued from the inflow port 82 functions as an overflow flow path through which the hot water stored in the tank body B to a position higher than the predetermined height is discharged, the hot water discharged from the tank body B is In addition to the inflow port 82, the inflow also flows from the gap between the actuating portion 81 and the positioning member 9. Therefore, the inflow port 82 is the main inflow path when the drainage flows into the overflow port 21 and the overflowed drainage does not necessarily flow from the inflow port 82.

As shown in FIGS. 7 and 8, the positioning member 9 is substantially circular in a front view, and in the state where the actuating portion 81 is attached, the guide portions 91 are formed at positions adjacent to the actuating portion 81. . Further, the positioning member 9 has a guiding portion upper portion 92 which matches the guiding portion lower portion 63 of the wire receiver 6 in the vicinity of the center, and has an opening through which the flange member 2 is inserted below the guiding portion upper portion 92 A locking portion 93 is attached to the opening.
The upper guide portion 92 is formed in an arc shape that matches the lower guide portion 63, and a groove 64 is formed in the center of the arc portion along the longitudinal direction. Also, the upper guide portion 92 is engaged with the lower guide portion 63.
The guide portion 91 is protruded toward the inside of the tank body B with an interval substantially equal to the width of the actuating portion 81 in the horizontal direction.
The locking portion 93 is an annular member, and is inserted into the cylindrical portion of the flange member 2 and attached to the positioning member 9 from the back surface, and the flange portion 23 of the flange member 2 is engaged during construction. It is stopped. Thus, the positioning member 9 is held between the flange portion 23 of the flange member 2 and the side wall of the tank body B.

  Here, the positioning member 9 prevents the wire receiver 6 from rotating relative to the positioning member 9 by the engagement of the upper guide portion 92 and the lower guide portion 63, and the guide portion 91 of the operating portion 81 By being disposed on both sides, the actuating portion 81 is prevented from rotating relative to the positioning member 9. That is, the positioning member 9 determines the direction of the wire receiver 6 and arranges the guide portions 91 on both sides of the actuating portion 91, thereby achieving the function of determining the position and the direction of the actuating portion 91.

  The drain valve apparatus comprised from said each member is constructed as follows. In addition, even if it does not describe in particular, the connection of the members which need watertightness is watertightly connected through watertight members, such as an adhesive agent and packing, as needed.

First, the drain 13 and the connection part 3 are connected by the overflow pipe 31. Then, the drainage plug 1 is inserted into the opening of the bottom of the tank body B, and the drainage 13 is screwed. Next, the locking portion 93 is inserted into the cylindrical portion of the flange member 2, and the locking portion 93 is attached to the positioning member 9. Then, the flange member 2 is inserted into the opening formed in the side wall of the tank body B, and is screwed with the connecting portion 3. At this time, as shown in FIG. 9, the positioning member 9 is disposed between the flange portion 23 of the flange member 2 and the inner wall of the tank body B, and the flange portion 23 is locked by the locking portion 93. Thus, the positioning member 9 is held between the opening peripheral edge formed on the inner side wall of the tank body B and the flange member 2. On the other hand, the positioning member 9 is rotatable with respect to the flange member 2 during the screwing, and the direction can be freely changed. Therefore, the positioning member 9 can be fixed in any direction with respect to the tank body B, and after the operator holds the positioning member 9 and adjusts the direction so that the operation unit 8 can be displaced in the vertical direction, The flange member 2 and the connecting portion 3 are further tightened and screwed until the positioning member 9 can not rotate. Thereby, the direction of the positioning member 9 is fixed.
Next, the transmission member 5 is inserted into the flange member 2 from the valve shaft 51 side end. At this time, the transmission member 5 is guided to the overflow pipe 31, and the valve shaft 51 reaches the inside of the drainer 13 more easily than the branch pipe portion 14. Then, the operator pulls out the valve stem 51 from the inside of the drainage plug 1, fixes the valve stem 51 to the wire fixing portion 12, and then attaches the wire fixing portion 12 to the drainage plug 1. Then, the valve stem 51 and the valve member 4 are fitted to complete the construction on the drainage plug 1 side.
Next, the attached portion 52 of the transmission member 5 is fixed to the mounting portion 62 of the wire receiver 6, and the wire retainer 73 is attached to the end of the inner wire 54, and then the wire receiver 6 is attached to the flange member 2. At this time, the upper guide portion 92 and the lower guide portion 63 are engaged, and the inner wire 54 exposed from the outer tube 53 is disposed in the groove 64. At this time, the wire receiver 6 and the positioning member 9 are non-rotatably fixed with the engagement of the upper guide portion 92 and the lower guide portion 63.
Finally, the actuating portion 81 is disposed between the guide portions 91 of the positioning member 9, and the construction of the drainage device is completed.

  As described above, in the installation procedure, the wire receiver 6 for determining the mounting position and direction of the operating portion 81 is fixed by engaging with the positioning member 9. In addition, when the actuating portion 81 is displaced, the actuating portion 81 is guided by the guides 91 disposed on both sides of the actuating portion 81. That is, in the present invention, the position and the direction of the actuating portion 81 are determined by the positioning member 9.

  As described above, in the drainage plug device completed in construction, a drainage port flow path through which drainage water is drained from the drainage port 11 and an overflow flow path through which drainage water is drained from the overflow port 21 are formed.

In the drainage plug device, the packing fitted around the valve member 4 closes the drainage port 11 by watertight contact with the upper surface of the drainage plug 1 in a state where the valve member 4 is lowered. . When a pressing operation is applied to the actuating portion 81 from the descent state of the valve member 4, the inner wire 54 slides toward the drain plug 1 as the actuating portion 81 descends, and the inner cylinder of the valve shaft 51 is from the outer cylinder. It protrudes and the valve member 4 is pushed up and raised. At this time, the lock mechanism 7 operates to hold the valve member 4 in the raised state. When the valve member 4 is in the raised state, the drainage port 11 is opened, and the hot and cold water in the tank body B can be discharged from the drainage port 11.
When a pressing operation is applied to the actuating portion 81 again, the lock mechanism 7 is actuated, and the valve member 4 is lowered by releasing the holding of the valve member 4 in the raised state. Thereby, the valve member 4 closes the drainage port 11 and it becomes possible to store hot and cold water in the tank body B.

On the other hand, when the water level in the tank body B reaches a predetermined level or more in the state where the drainage port 11 is closed, the hot water in the tank body B is discharged from the overflow port 21 as shown in FIG. In FIG. 10, in order to facilitate understanding of the invention, the description of the wire receiver 6 and the transmission member 5 is omitted from the state of FIG. 2, and the flow of drainage at the time of overflow is described by arrows. Here, the overflow port 21 is covered by the operation unit 8, but the bottom surface of the operation unit 81 is opened to form an inflow port 82. Therefore, the overflow water in the tank body B can discharge hot and cold water from the overflow port 21 through the back side of the operation portion 81 from the inflow port 82. Further, the hot and cold water discharged from the overflow port 21 flows into the drainer 13 from the branch pipe portion 14 through the connection portion 3 and the overflow pipe 31.
Note that, as shown in FIG. 6, since the collection unit 66 is disposed at the inflow port 82, large-sized dust, toys, and the like are not discharged through the inflow port 82. In addition, the collection portion 66 can also prevent the user from putting a finger or the like into the apparatus through the inflow port 82.

  In the present invention, since the overflow port 21 is covered by the operation unit 8 so as not to be visible, the design can be improved. On the other hand, since the overflow port 21 is always in the open state regardless of the state of the valve member 4, the flow rate of the drain pipe continuing from the overflow port 21 does not decrease.

Further, at the time of construction, the positioning member 9 can be fixed in any direction, and the position and the direction of the actuating portion 81 are determined by the positioning member 9. Therefore, in the present invention, it is possible for the operator to adjust the positioning member 9 so as to fix it in any direction, and to improve the workability. In the case of the above embodiment, the operating portion 81 is configured to move up and down along the inner surface of the tank body B, and the inlet 82 is provided below the operating portion 81. The design is good regardless of the state of the opening / closing of the drainage port 11 without visual observation.
Instead of the above embodiment, for example, the operation part 8 opens and closes the drainage port 11 by operating the operation part 81 right and left along the inner surface of the tank body B, and the inflow port 82 is provided below the operation part 81 Also in this configuration, the inflow port 82 is not viewed by the user in use, and the drainage plug device can be made to have a good design regardless of the state of the opening / closing port of the drainage port 11.
Further, in the present invention, since the positioning member 9 is held and fixed by the peripheral edge of the opening formed on the inner side wall of the tank body B and the flange member 2, the opening for attaching the operation portion 8 may be circular. It becomes possible. That is, since it is not necessary to make the opening rectangular in order to determine the position and orientation of the positioning member 9, the formation of the opening is easy. Further, since the opening can be made circular, it is possible to use screwing for assembling the members, and a complicated assembling method by screwing or bonding is not required.

Although the embodiment of the present invention is the above, the flush stop device of the present invention is not limited to the shape of the above embodiment. For example, in the case of the above embodiment, the operating portion 81 is configured to move up and down along the inner surface of the tank body B, and the inflow port 82 is provided below the operating portion 81. It is not visible to the user, and the design is good regardless of the state of the opening / closing of the drainage port 11.
Instead of the above embodiment, the operating portion 8 is opened and closed by operating the operating portion 81 right and left along the inner surface of the tank body B, and the inflow port 82 is provided below the operating portion 81. Also as a configuration, the inflow port 82 is not viewed by the user in use, and the drainage plug device can be made to have a good design regardless of the state of the opening / closing of the drainage port 11.
Moreover, the drainage plug apparatus of this invention is not restricted to the drainage plug apparatus of a bathtub, You may be used for a washbasin or a kitchen.
Moreover, in the said embodiment, although it is comprised so that the operation part 8 and the transmission member 5 may be combined with piping of an overflow, this invention is not limited to the said embodiment, Attachment of the operation part 8, As a configuration in which an opening only for inserting the transmission member 5 is provided in the tank body B, it is adopted for a tank body without an overflow pipe, or a configuration provided with an operation portion 8 and the transmission member 5 independent of the overflow pipe. Also good.
In the above embodiment, the opening to which the operation unit 8 is attached is formed on the inner side wall of the tank body B. However, the opening may be provided on the outer wall or the edge of the tank body B. It may be formed on a nearby wall surface. As described above, since the overflow piping is not essential for the construction of the operation unit 8 and the transmission member 5, no problem occurs even if the operation unit 8 of the present invention is provided on the outer wall or the edge of the tank body B.
