Description

The present invention relates to a remote-controlled drain plug device that opens and closes a drain port of a tank body by operating an operation unit provided at a position away from the drain port.

Conventionally, in order to treat the drainage generated inside the tank body such as a bathtub or a washbasin, a drainage port is provided on the bottom surface of the tank body, etc., and the drainage is discharged from this drainage port to the sewage side via a piping member. Is widely known. In addition, there is a method of collecting water in the tank by arranging the lid so as to cover the drain, and opening the drain by raising the lid and separating it from the drain. A remote-operated drainage device that opens and closes the drainage port by raising and lowering is known by operating a position away from the lid and the drainage port, for example, an operation unit provided at the edge of the tank body or above the side surface of the tank body. There is.
As a widely known remote-operated drainage device, a drainage port provided on the bottom surface of a bathtub as a tank body as described in Patent Document 1 and a drainage port are opened and closed by moving up and down on the drainage port. The drainage port is equipped with a lid, a support part arranged in the drainage port to move the lid up and down, an operation part provided in the flange part provided on the peripheral edge of the opening of the bathtub, and an operation applied to the operation part. There is one composed of a release wire transmitted to the supported support portion and a lock mechanism for fixing the operation of the release wire.
The release wire is composed of a flexible tubular outer tube and a flexible inner wire that slides in the outer tube.
In the remote-controlled drainage device of Patent Document 1, when an operation is performed on the operation unit, the operation is transmitted to the support portion in the drainage port via the inner wire of the release wire, and the lid moves up and down. When the lid is lowered by remote control, the lid comes into contact with the circumference of the drainage port, so that the drainage flow path is eliminated and the drainage port can be closed. In addition, when the lid rises, the lid separates from the periphery of the drain and the drain opens, so if there is hot water in the tank, it is drained from the drain to the sewage side via the drain pipe. be able to.

In the remote-controlled drain plug device, the operation unit has a part such as an operation button that the user directly contacts to operate. In the remote-operated drain plug device described in Patent Document 1, each time the user pushes the operation button into the operation button, the lid is fixed in an raised state, the drain port is opened, the fixing is released, and the lid is lowered. The drainage port is closed and the drainage port is closed alternately.
Here, the opening / closing of the lid and the advance / retreat of the operation button are linked via the inner wire of the release wire, and in the remote operation type drain plug device described in Patent Document 1, the lid is raised and the drain port is drained. The operation button is lowered when the door is open, and the operation button is raised when the lid is lowered and the drainage port is closed.

By the way, the remote-controlled drain plug device described in Patent Document 1 is a remote-controlled drain plug device for a bathtub, and the operation unit is provided in a flange portion provided at an opening of the bathtub.
Since the opening of the bathtub is covered with a bath lid or the like for the purpose of keeping the bath water warm, if the operation unit is located on the collar of the bathtub, the operation unit is covered with the bath lid from above. For this reason, if the operation button protrudes from the collar, when the bathtub covers the opening of the bathtub, the operation button is placed on the bathtub to be pushed and operated, and the remote-controlled drainage is performed. The plug device may malfunction. In order to avoid this, the operation button of the operation unit of the bathtub described in Patent Document 1 has the upper end of the operation button in the most raised state, that is, when the lid is lowered and the drain port is closed. It is configured to be substantially the same as the upper surface of the collar of the bathtub. By doing so, even if the opening of the bathtub is covered with the bathtub lid, the operation button is not pushed into the bathtub lid, and the drain port is prevented from opening and closing due to a malfunction.

Japanese Unexamined Patent Publication No. 2016-172961

There is a desire to make the space below the bathtub as narrow as possible in the vertical direction with respect to the ground plane. For example, by narrowing the space below the bathtub, the height required to cross the upper edge of the bathtub is lowered by that amount, and it becomes easier to cross the bathtub when taking a bath. Further, if the space under the floor where the bathtub is installed is narrowed in the height direction, the living space on the floor can be widened up and down by that amount, and there is an advantage that the living space can be made comfortable.
Therefore, it is required to narrow the width of the drainage pipe in the height direction as much as possible. Therefore, the applicant provides a protrusion on the side surface of the bathtub, inserts a release wire through the protrusion from above, fixes the outer tube to the protrusion and the operation part of the bathtub, and interlocks one end of the inner wire with the operation button. We invented a structure in which the other end is connected to the lid from above and the drain port is opened and closed. By doing so, it is not necessary to arrange the support portion and the release wire of the remote-controlled drain plug device below the drain port, and the space below the bathtub can be narrowed to that extent with respect to the ground plane.

However, the structure described in paragraph 0006 has the following problems.
In the remote-operated drain plug device having the structure described in paragraph 0006, in which the outer tube is fixed to the bathtub and the operation unit, and the inner wire is fixed to the operation button and the lid, the inner wire drains when the operation button is lowered. A state in which the lid moves forward to the mouth side, the lid covers the drainage port and is closed, and when the operation button is raised, the inner wire retracts to the operation unit side and the lid is opened away from the drainage port. It becomes.
That is, in the remote-controlled drain plug device having the configuration as described in paragraph 0006, the operation button is raised when the drain port changes from the closed state to the open state.
If the upper end of the operation button is configured to be substantially the same as the upper surface of the bathtub collar when the drainage port is closed, the bathtub lid will protrude from the bathtub collar when the drainage port is open. When the opening of the bathtub is covered with the bathtub, the operation button is placed on the bathtub lid to be pushed and operated, and the remote-operated drain plug device may malfunction.
However, if the upper end of the operation button is configured to be substantially the same as the upper surface of the collar of the bathtub when the drain is open, when the drain is closed, the position is recessed from the collar of the bathtub. There is a problem that the design deteriorates due to the descent. Further, the bathtub is for bathing with the drainage port closed, and if the bathtub is bathed when the operation button is recessed, there is a problem that hot water overflowing from the bathtub is collected in the recessed portion. When hot water collects in the recessed part, hot water enters the lock mechanism, etc., and the surface tension of the liquid interferes with the operation of the lock mechanism, causing a malfunction, or when the operation button is operated, the operation button rises. There was a problem that the hot water in the dented part was scattered.
The present invention has been invented in view of the above problems. In a remote-operated drain plug device having a configuration in which a lid is pulled up from above, an operating body such as an operation button rises when the drain port is closed. It provides a remote-operated drain plug device in which an operating body such as an operation button descends when the drain port is open.

Further, when assembling the product at the factory, the release wire 10 is assembled in a state of being connected and fixed to the lock mechanism 9. Specifically, first, the outer tube 10a of the release wire 10 is connected and fixed to the lock mechanism main body 9a which is the casing body of the lock mechanism 9. By this connection, the outer tube 10a is connected and fixed to the lock mechanism main body 9a, and the end portion of the inner wire 10c is arranged so as to abut on the lock shaft 9b. Since the inner wire 10c is always urged toward the lock mechanism 9 by the action of the return spring, this connection brings the upper end of the inner wire 10c into constant contact with the lower end of the lock shaft 9b. Further, by this connection, the inner wire 10c is connected by abutting on the lock shaft 9b each time the lock shaft 9b is pushed into the lock shaft 9b and the lock shaft 9b is fixed / released in the lowered state. In the state of being lowered, the fixing / fixing is released, and the action of the return spring causes the lock shaft 9b to rise together with the lock shaft 9b, and the operation is repeated alternately.
First, the operation unit main body 8a is attached to the operation unit attachment hole B4 of the bathtub B.
Next, the drainage port main body 1 is attached to the attachment hole B2 of the bathtub B. At this time, the female screw of the joint pipe 2 is screwed into the male screw of the drainage port main body 1 in a state where the upper surface of the peripheral surface of the mounting hole B2 of the bathtub B is in contact with the lower surface of the flange portion 1b of the drainage port main body 1. The peripheral edge of the mounting hole B2 of the bathtub B is sandwiched and fixed between the lower surface of the flange portion 1b and the upper surface of the joint pipe 2.
Next, a pipe member P such as a bent pipe or a straight pipe is combined, and the pipe member P connects from the downstream end of the joint pipe 2 to the pipe on the sewage side. In the figure, only the portion where the straight pipe piping member P is connected to the downstream end of the joint pipe 2 is shown, and other configurations are omitted.
Next, the perforated plate member M is arranged inside the drain port 1a.
Next, after inserting the drainage port 1a side end portion provided with the wire shaft portion 10d of the release wire 10 into the inside of the operation unit main body 8a, the lock mechanism main body 9a is connected and fixed in the operation unit main body 8a, and further. The operation button 8b is arranged in the operation unit main body 8a and connected to the end portion of the lock shaft 9b.
Next, the end portion of the release wire 10 on the drain port 1a side is connected to the mechanism portion 4.
To specifically explain the connection method, first, the end portion of the arm portion 6a of the pull-up shaft 6 is fitted and connected from the side surface of the cylindrical portion 10b at the end portion of the outer tube 10a.
Next, the pulling shaft 6 is passed through the through hole 5b of the mechanism portion main body 5, and the wire shaft portion 10d at the tip of the inner wire 10c is connected and fixed to the fixing portion 5c of the mechanism portion main body 5, and the mechanism portion of the release wire 10 is fixed. The connection to 4 is completed.
Next, the cylindrical portion 5a of the mechanism portion 4 is inserted into the insertion hole B5 of the protruding portion B1, and the cylindrical portion 5a of the mechanism portion 4 is fitted and fixed to the insertion hole B5 using the C-shaped ring 7.
Further, the fitting portion 3a of the lid 3 is fitted to the lower end of the pulling shaft 6 of the mechanism portion 4, and the construction of the remote-controlled drain plug device of the present invention and the drain pipe of the bathtub B is completed.
In the embodiment configured as described above, the wire shaft portion 10d, which is the end portion of the inner wire 10c on the drain port 1a side, is fixed to the mechanism portion main body 5, and the mechanism portion main body 5 is inserted as a part of the bathtub B. Since it is fixed to the hole B5, in the above embodiment, the end portion of the inner wire 10c on the drain port 1a side is fixed to the bathtub B which is a tank body. Further, since the cylindrical portion 10b which is the end portion of the outer tube 10a on the drain port 1a side is fixed to the pulling shaft 6 and the pulling shaft 6 is fixed to the lid body 3, the drain port 1a of the outer tube 10a is fixed. The side end portion is fixed to the lid 3 via the pull-up shaft 6.
In addition, as a design matter, when the construction is completed, the upper end of the operation unit main body 8a is attached so as to be slightly higher than the upper surface of the flange portion B3 of the bathtub B, but the functional and design are almost the same. Can be installed at a high position. Further, when the remote-controlled drain plug device is used, the upper surface of the operation button 8b, which is an operation body, is the operation unit main body 8a in a state where the lid 3 is in contact with the peripheral edge of the drain port 1a and the drain port 1a is closed. It is configured to be substantially the same as the upper end of. That is, when the construction is completed and the drainage port 1a is closed, the operation button 8b, which is an operation body, is designed to be substantially the same as the upper surface of the flange portion B3 of the bathtub B, which is a tank body.

The method of using the remote-controlled drainage device of the above embodiment will be described below.
When the remote-controlled drainage device configured as described above is used, as shown in FIG. 1, the lid 3 is first lowered to close the drainage port 1a. At this time, the operation button 8b is substantially the same as the upper surface of the flange portion B3 of the bathtub B.
When the operation button 8b is pushed from this state, the lock shaft 9b of the lock mechanism 9 is fixed in a lowered state, that is, pushed in the direction of the inner wire 10c arranged below, and is an operating body. The operation button 8b also stops in a state of being recessed from the upper edge of the operation unit main body 8a.
Here, the inner wire 10c slides in the outer tube 10a, but since the end portion of the inner wire 10c on the drain port 1a side is fixed to the bathtub B, the end portion on the drain port 1a side operates. There is no. As a result, the length of the inner wire 10c from the tip of the wire shaft portion 10d, which is the end on the drain port 1a side, to the connection portion of the outer tube 10a with the lock mechanism 9, is pushed in more than before the pushing operation of the operation button 8b. This means that it has been extended by the length of the procedure. Since both the inner wire 10c and the outer tube 10a have rigidity in the axial direction and flexibility in the side surface direction, the release wire 10 is an extension of the inner wire 10c and draws an arc or the like on the side. Or, if an arc is originally generated, the arc is deformed so that the diameter of the arc becomes large.
On the other hand, since the inner wire 10c is inserted into the outer tube 10a, the shape of the outer tube 10a is bent or the arc is increased in diameter following the inner wire 10c, but the connection portion with the lock mechanism 9 is fixed. The outer tube 10a itself is not extended. The end portion of the outer tube 10a on the operation portion 8 side is fixed to the operation portion main body 8a via the lock mechanism 9, but the end portion on the drain port 1a side is fixed to the lid 3 via the pull-up shaft 6. However, the lid 3 is not fixed to the bathtub B or the drain port 1a. In this way, while the inner wire 10c is extended, the outer tube 10a is not extended, so that the outer tube 10a is relatively shortened by the pushing length of the operation button 8b, and the pulling shaft 6 is relatively shortened by that length. And the lid 3 connected to the pulling shaft 6 is pulled upward. As a result, as shown in FIG. 2, the pull-up shaft 6 and the lid 3 connected to the outer tube 10a rise and separate from the drain port 1a, so that the drain port 1a opens. If there is hot water or the like in the bathtub B, the hot water is discharged from the drain port 1a as drainage.
If hair or the like is mixed in the drainage, it is collected by the perforated member M.
When the operation button 8b is pushed again from this state, the lock shaft 9b of the lock mechanism 9 is released from being fixed, and the lock shaft 9b of the lock mechanism 9 rises due to the action of the return spring, that is, opposite to the inner wire 10c. The length of the inner wire 10c from the tip of the wire shaft portion 10d, which is the end on the drain port 1a side, to the connection portion of the outer tube 10a with the lock mechanism 9, is such that the inner wire 10c is the drain port. Return to the original length when 1a was closed.
Further, at this time, the operation button 8b is substantially the same as the upper surface of the flange portion B3 of the bathtub B.
Therefore, the pull-up shaft 6 connected to the drainage port 1a side end of the outer tube 10a descends, and the lid 3 connected to the lower end of the pull-up shaft 6 comes into contact with the peripheral edge of the drainage port 1a and drains. By covering 1a, the drainage port 1a is closed.
After that, the drainage port 1a can be opened and closed by remote control by pressing the operation button 8b located at a position away from the drainage port 1a.

Examples of the present invention are as described above, but the present invention is not limited to the above examples and can be freely changed without changing the gist of the invention.
For example, in the above embodiment, the bathtub B is adopted as a tank body, but the present invention is not limited to the above embodiment, and the present invention is not limited to the above embodiment, but may be applied to other tank bodies such as a washbasin of a washbasin and a sink of a sink. You may adopt it.
