The operation of this thrust lock mechanism will be described. When the support shaft 4 is pushed up from the state shown in FIG. 3A, the rotating cam ring 6b is sandwiched between the casing portion 6c and the fixed cam ring 6a and slightly rotates. The state shown in (b) of FIG. When the push-up of the support shaft 4 is finished and the support shaft 4 is lowered, the convex portion of the rotating cam ring 6b meshes with the inclined wall 6d of the casing portion 6c, as shown in FIG. Then, the support shaft 4 stops in a support state in which it protrudes from the casing portion 6c. When the support shaft 4 is pushed up again from this state, as shown in FIG. 3D, the rotating cam ring 6b is also sandwiched between the casing portion 6c and the fixed cam ring 6a and slightly rotated. When the push-up of the support shaft 4 is finished and the support shaft 4 is lowered, the convex portion of the rotating cam ring 6b moves to the groove portion 6e side of the casing portion 6c by rotation and meshes with the inclined wall 6d of the casing portion 6c. Therefore, the support shaft 4 is lowered and returns to the support release state shown in FIG. 3A through the state shown in FIG. Thereafter, by repeating this operation, support / support release of the support shaft 4 can be freely selected.
The shape memory alloy 5a, which is an electric part of the present embodiment, is a linear shape that shrinks due to heat. When the shape memory alloy 5a itself has an electric resistance inside and energizes, it generates heat as a heat source body, and reacts to the generated heat. Contracts. As shown in FIG. 4 to FIG. 6, a part of the shape memory alloy 5a is fixed to the support shaft 4 and a part is fixed to the fixing member 9, respectively. When is contracted, the support shaft 4 is pushed up, and finally the thrust lock mechanism is operated.
The receiving unit 10 is disposed outside the drainage pipe, receives an operation radio wave transmitted from the operation unit 3, supplies power from the power supply unit 11 to the shape memory alloy 5a, and operates the shape memory alloy 5a. In the receiving unit 10, when the operation radio wave from the operation unit 3 is received and the shape memory alloy 5 a is energized, the shape memory alloy 5 a is contracted by energization for several seconds in advance. 4 is sufficiently energized after a sufficient time for the thrust lock mechanism to operate to a sufficient extent to operate the thrust lock mechanism, and then for a predetermined number of seconds (the contracted shape memory alloy 5a is subjected to water pressure and valve members). The power supply is stopped regardless of the operation of the operation unit 3 for a sufficient time to extend again due to its own weight. When radio waves from the operation unit 3 are received and energization is started, the operation unit 3 is additionally operated until the set energization time and energization stop time elapses, and the operation radio waves are received. Also, the receiving unit 10 processes it as invalid. After the energization time and the energization stop time have elapsed, the receiving unit 10 receives the operation radio wave transmitted from the operation unit 3 again, supplies power from the power supply unit 11 to the shape memory alloy 5a, and receives the shape memory alloy 5a. Can be operated.
The power supply unit 11 is a member that is arranged outside the drainage pipe and is wired to the receiving unit 10.
The operation unit 3 is a member that transmits an operation signal to the control unit by radio waves for each operation.

The remote-operated drain plug device of the first embodiment described above is constructed and attached as follows.
After the drain plug body 7 is inserted into the mounting port of the bathtub B from above, the female screw of the elbow pipe 8 is screwed into the male screw of the drain cock body 7, and the lower surface of the flange 7a of the drain plug body 7 and the upper edge of the elbow pipe 8 And fix the peripheral edge of the mounting opening. Further, the discharge port 8a is connected to a pipe on the sewage side.

At this time, the thrust lock mechanism is in the state shown in FIG. In this state, when the operation unit 3 is operated and the operation unit 3 transmits a radio wave and the reception unit 10 receives the radio wave, the shape memory alloy 5a which is an electric unit is energized and generates heat correspondingly. . In response to this heat generation, the shape memory alloy 5a contracts, and as a result, the support shaft 4 of the holding mechanism is pushed upward as shown in FIG. At this time, the thrust lock mechanism is in the state shown in FIG. Thereafter, when the energization of the shape memory alloy 5 a is released by the receiving unit 10, the shape memory alloy 5 a expands again due to the weight of the valve member 2 and the support shaft 4. Thereby, the support shaft 4 is slightly lowered and the valve member 2 is fixed in the raised state, the state shown in FIG. 6 is reached, the drain port 1 is opened, and the waste water in the bathtub B is discharged. At this time, the thrust lock mechanism is in the state shown in FIG.
When the operation unit 3 is operated again from this state, the operation unit 3 transmits a radio wave, and the reception unit 10 receives the radio wave. When the shape memory alloy 5a is energized and generates heat, the shape memory alloy 5a contracts again. As a result, the support shaft 4 of the holding mechanism is pushed upward. At this time, the thrust lock mechanism is in the state shown in FIG. Thereafter, when the energization of the shape memory alloy 5 a is released by the operation of the receiving unit 10, the shape memory alloy 5 a expands again due to the weight of the valve member 2 and the support shaft 4. As a result, the support shaft 4 descends in the thrust lock mechanism, returns to the state of FIG. 3A through the state of FIG. 3E, and the drain port 1 becomes the state of FIG. Is closed. Thereafter, by repeating this process, the drain port 1 can be freely opened / closed remotely.

The remote-operated drain plug device of the first embodiment has the following effects.
The remote-operated drain plug device of the first embodiment can be opened and closed by an expansion / contraction by energizing the shape memory alloy 5a and a thrust lock mechanism that is a holding mechanism. Since this opening and closing operation does not use human power, the drain port 1 can be easily opened and closed even if the user does not have much arm strength or the like.
In the remote-operated drain plug device of the first embodiment, the shape memory alloy 5a, which is an electric part, is energized only for a few seconds when the opening / closing operation occurs, and the open or closed state is maintained. There is no need to energize it. Therefore, power consumption due to energization in the operation is very small, and the burden on the device can be reduced.

Next, a second embodiment of the present invention will be described with reference to the drawings. The remote-operated drain plug device of the second embodiment of the present invention shown in FIG. 7 includes a drain plug body 7 having a drain port 1, an elbow pipe 8, a valve member 2 attached to a bathtub B as a tank body. The fixing member 9, the operation unit 3, the power supply unit 11, and the receiving unit 10 are included.
The bathtub B is a box body that is open at the top, and has an opening for attaching the drain plug body 7 to the bottom surface.
The drain plug body 7 is a member that is cylindrical and has an external thread on the outer surface, and is provided with a flange 7a that protrudes outward at the upper end, into which the drainage in the bathtub B is directed to the sewage side. A drain port 1 for draining is provided.
The elbow pipe 8 is a member obtained by bending a pipe body into a substantially L shape, and has an internal screw threadedly engaged with a male screw of a drain plug main body 7 at an upper opening of the cylindrical body. Is connected to a pipe on the sewage side and is provided with a discharge port 8a for discharging waste water to the sewage side. In addition to the discharge port 8a, the side surface is provided with an insertion hole 8b for watertightly inserting an electric wire connecting the bimetal 5b and the power supply unit 11.
The valve member 2 is a substantially flat plate member having a circular shape in a plan view for closing the upper end of the drain port 1, and is fitted and fixed to the distal end of a support shaft 4 of a holding mechanism section described later at the center of the lower surface.
The fixing member 9 is a member for fixing the holding mechanism section described below, the bimetal 5b as the electric section, and the control section inside the drain plug, and is fitted and fixed inside the drain plug.
The holding mechanism section is configured by a well-known one-way cam mechanism that is used for an opening / closing mechanism of an audio cabinet. Specifically, the one-way cam mechanism will be described. As shown in FIG. 8, a casing portion 6c having a sliding hole 6g and a one-way cam portion 6f including a locking portion 6h, an inclined portion 6i, and a protruding portion 6j. And a support shaft 4 on which a contactor 6k is rotatably mounted so as to engage with the one-way cam portion 6f in such a manner that the engagement portion alternately repeats raising and lowering with respect to the engaging portion every time the elevator is raised and lowered. Become.
Explaining these arrangements, first, as shown in FIG. 8A, the upper and lower sliding holes 6g are provided in the casing portion 6c, and the support shaft 4 is slidably disposed on the sliding shaft. The Further above, as shown in FIG. 8B, the one-way cam portion 6f and the contact 6k are disposed so as to be engageable with each other.
The operation of this one-way cam mechanism will be described. As shown in FIG. 9A, the support shaft 4 is lowered. When an operation is applied to the support shaft 4 from this state and the support shaft 4 is pushed up, the support shaft 4 changes from the state shown in FIG. 9A to the state shown in FIG. 9B, that is, the one-way cam portion 6f. The contact 6k comes into contact with the protrusion 6j and is inclined. Further, when the operation to the support shaft 4 is finished and the support shaft 4 is in a free state, the contact 6k of the support shaft 4 moves to a position where it is locked by the locking portion 6h and the inclined portion 6i by its own weight, It stops in the state shown in FIG. In the state shown in FIG. 9C, the support shaft 4 is positioned above the state shown in FIG.
When the support shaft 4 is operated again from this state and the support shaft 4 is pushed upward, the contact 6k comes into contact with the protrusion 6j of the one-way cam portion 6f again as shown in FIG. 9 (d). The contact 6k is inclined. Thereafter, when the operation to the support shaft 4 is finished and the support shaft 4 is in a free state, the support shaft 4 is lowered by its own weight to be in the state shown in FIG. 9 (e). For this reason, there is no locking between the locking portion 6h of the one-way cam portion 6f and the contact 6k. Therefore, the state shown in FIG. In other words, the support shaft 4 returns to the most lowered state. Thereafter, by repeating this operation, support / support release of the support shaft 4 can be freely selected.
The bimetal 5b, which is an electric part of the present embodiment, is a metal piece that is bent by heating by bonding two types of metals having different coefficients of thermal expansion. In particular, the bimetal 5b of this embodiment itself has an electrical resistance, and generates heat as a heat source when energized. By this heat, the bimetal 5b is deformed from the “U” shape to the “<” shape, and reacts to the generated heat to perform the above-described deformation. As shown in FIG. 7 or FIG. 10 to FIG. 12, a part of the bimetal 5b is fixed to the support shaft 4 and a part is fixed to the fixing member 9, respectively. Is deformed, the support shaft 4 is pushed up, and finally the one-way cam mechanism is operated.
The receiving unit 10 is disposed outside the drainage pipe, receives operation radio waves transmitted from the operation unit 3, supplies power from the power supply unit 11 to the bimetal 5b, and operates the bimetal 5b. When the receiving unit 10 receives an operation radio wave from the operation unit 3 and energizes the bimetal 5b, the bimetal 5b is energized for several seconds (the bimetal 5b is energized and the support shaft 4 is moved by the one-way cam mechanism. The energization is automatically terminated after a sufficient time for the ascending operation enough to operate, and the bimetal 5b deformed into a "<" shape is again set by natural cooling for a few seconds. Energization is stopped regardless of the operation of the operation unit 3 for a sufficient time to be deformed into a U-shape. When radio waves from the operation unit 3 are received and energization is started, the operation unit 3 is additionally operated until the set energization time and energization stop time elapses, and the operation radio waves are received. Also, the receiving unit 10 processes it as invalid. After the energization time and the energization stop time have elapsed, the receiving unit 10 receives the operation radio wave transmitted from the operation unit 3 again, and supplies power from the power supply unit 11 to the bimetal 5b to operate the bimetal 5b. Is possible.
The power supply unit 11 is a member that is arranged outside the drainage pipe and is wired to the receiving unit 10.
The operation unit 3 is a member that transmits an operation signal to the control unit by radio waves for each operation.

The remote-operated drain plug device of the second embodiment described above is constructed and attached as follows.
After the drain plug body 7 is inserted into the mounting port of the bathtub B from above, the female screw of the elbow pipe 8 is screwed into the male screw of the drain cock body 7, and the lower surface of the flange 7 a of the drain plug body 7 and the upper edge of the elbow pipe 8 And fix the peripheral edge of the mounting opening. Further, the discharge port 8a is connected to a pipe on the sewage side.
And the operation part 3 is attached and fixed to the opening periphery of the bathtub B, Furthermore, an electric wire is inserted watertightly into the drain outlet 1 through the insertion hole 8b of an elbow member, and the electric wire inside the drain outlet 1 is fixed to the fixing member 9. The electric wires on the outside of the drain port 1 are connected to the power source 11 respectively.
Further, after fixing and fixing the fixing member 9 inside the drain port 1, the valve member 2 is fitted to the upper end of the support shaft 4, and the power supply unit 11 is arranged and fixed at an appropriate position near the tank body, The construction of the remotely operated drain plug device to the bathtub B which is a tank body is completed.

The remote-operated drain plug device of the second embodiment attached as described above operates as follows. First, as shown in FIG. 10, the valve member 2 is lowered and the drain port 1 is closed.
At this time, the one-way cam mechanism is in the state shown in FIG.
In this state, the operation unit 3 is operated, and when the operation unit 3 transmits radio waves and the reception unit 10 receives radio waves, the bimetal 5b, which is an electric unit, is energized correspondingly and used as a heat source. The bimetal 5b generates heat. In response to this heat generation, the bimetal 5b is deformed from a “U” shape into a “<” shape by heat, and accordingly, the support shaft 4 of the holding mechanism is pushed upward.
At this time, the one-way cam mechanism is in the state shown in FIG. Thereafter, when the energization of the bimetal 5b is canceled by the receiving unit 10, the bimetal 5b is cooled and deformed from a “<” shape to a “U” shape.
As a result, the support shaft 4 is slightly lowered and the valve member 2 is fixed in the raised state, the state shown in FIG. 12 is opened, the drain port 1 is opened, and the waste water in the bathtub B is discharged. At this time, the one-way cam mechanism is in the state shown in FIG.
When the operation unit 3 is operated again from this state, the operation unit 3 transmits a radio wave, and the reception unit 10 receives the radio wave, thereby energizing the bimetal 5b which is an electric unit and generating heat. The “U” shape is deformed by heat to a “<” shape, and the support shaft 4 of the holding mechanism is pushed upward accordingly. At this time, the one-way cam mechanism is in a state shown in FIG. Thereafter, when the energization of the bimetal 5b is released by the operation of the receiving unit 10, the bimetal 5b is cooled and deformed from a “<” shape to a “U” shape. As a result, the support shaft 4 is lowered in the one-way cam mechanism, returns to the state of FIG. 9A through the states of FIGS. 9E and 9F, and the drain port 1 is in the state of FIG. Thus, the drain port 1 is closed. Thereafter, by repeating this process, the drain port 1 can be freely opened / closed remotely.

The remote-operated drain plug device of the second embodiment has the following effects.
The remote-operated drain plug device of the second embodiment can be opened and closed by deformation by energization of the bimetal 5b which is an electric part and a one-way cam mechanism which is a holding mechanism part. Since no human power is used, the drain port 1 can be easily opened and closed even if the user does not have much arm strength or the like.
Further, in the remote-operated drain plug device of the second embodiment, energization of the bimetal 5b, which is an electric part, is only performed for a few seconds when the opening / closing operation occurs, and the opening state or the closing state is maintained. There is no need to turn on the power. Therefore, power consumption due to energization in the operation is very small, and the burden on the device can be reduced.

Next, a third embodiment of the present invention will be described with reference to the drawings. The remote-operated drain plug device according to the third embodiment of the present invention shown in FIGS. 13 to 14 is a drain plug body 7 having a drain port 1, an elbow pipe 8, a valve attached to a bathtub B as a tank body. The unit 12 includes a valve member 2 and a fixing member 9, and an operation unit 3 (not shown). In the above configuration, the drain plug main body 7 and the elbow pipe 8 are members provided by a drainage equipment manufacturer as drainage equipment. Further, the valve unit 12 and the operation unit 3 including the valve member 2 and the fixing member 9 are members provided from a water heater manufacturer as a part of the water heater.

The holding mechanism section has the same configuration as the thrust lock mechanism of the first embodiment described in paragraph 0023, and further includes a second magnet 5d made of a permanent magnet at the lower end of the support shaft 4. In addition, a sensor (not shown) is provided between the side surface of the support shaft 4 and the thrust lock mechanism, and the height position of the support shaft 4 is detected to detect whether the drain port 1 is open or closed. The data is sent to the operation unit 3.
The first magnet 5c includes an electromagnet that generates a magnetic force when energized, and repels the second magnet 5d of the support shaft 4 when energized to push the support shaft 4 upward and operate the thrust lock mechanism.
The receiving unit 10 is a member that is wired to the first magnet 5 c in the fixed member 9, receives an operation from the operation unit 3, and accordingly is supplied from the power supply unit 11 provided in the fixed member 9. Is supplied to the first magnet 5c. In the receiving unit 10, when the operation radio wave from the operation unit 3 is received and the first magnet 5 c is energized, the first shaft 5 c is energized for several seconds (the first magnet 5 c is energized to Energization is automatically terminated after a sufficient time for the thrust lock mechanism to move up enough to operate. When the radio wave of the operation unit 3 is received and energization is started, even if the operation unit 3 is additionally operated until the set energization time elapses and the radio wave of the operation is received, the reception unit At 10, it is treated as invalid. After the energization time has elapsed, the receiving unit 10 receives the operation radio wave transmitted from the operation unit 3 again, supplies power from the power supply unit 11 to the first magnet 5c, and operates the first magnet 5c. Is possible.
The power supply unit 11 is a member provided with a battery therein, and supplies power to the receiving unit 10.
The operation unit 3 is a member that transmits an operation signal to the receiving unit 10 by radio waves for each operation. In this embodiment, the valve member 2, the fixing member 9, and the operation unit 3 are configured as a part of the member of the water heater, and the operation unit 3 is disposed in the operation panel that is the operation unit 3 of the water heater. It is configured as an integral unit. In this operation section 3, the operation and stop of the water heater, the opening / closing operation of the drainage port 1 of the bathtub B, and the operation of storing hot water at a preset water level / temperature in the bathtub B, so-called "hot water filling" Operations can be performed. Further, in this embodiment, two operation units 3 are prepared, one being attached and fixed to the wall surface in the bathroom and one to the wall surface of the living space such as a kitchen. The two operation units 3 are basically the same except for the design and the like, and the operation performed by the operation unit 3 in the bathroom can also be performed by the operation unit 3 on the living space side. In addition, there is no particular difference as a member, for example, the operation performed in the operation unit 3 in the bathroom can be stopped in the operation unit 3 on the living space side. Further, the operation unit 3 of this embodiment receives detection data of the height position of the support shaft 4 detected by the holding mechanism unit, and whether the drain port 1 is open (the support shaft 4 is raised), It is configured to display on the operation unit 3 whether the mouth is closed (the support shaft 4 is lowered). Furthermore, even if a hot water supply / water supply operation is performed on the operation unit 3, when it is detected from the detection data that the drain port 1 is open, the fact that the drain port 1 is open is displayed and the bathtub B is displayed. It is configured not to supply hot water or water.

The above-described remote-operated drain plug device according to the third embodiment of the present invention is constructed and attached as follows. After the drain plug body 7 is inserted into the mounting port of the bathtub B from above, the female screw of the elbow pipe 8 is screwed into the male screw of the drain cock body 7, and the lower surface of the flange 7a of the drain plug body 7 and the upper edge of the elbow pipe 8 And fix the peripheral edge of the mounting opening. Further, the discharge port 8a is connected to a pipe on the sewage side.
This completes the construction on the drain pipe side.
After that, as construction work on the water heater side, along with the construction of the water heater, one of the operation units 3 is attached in the vicinity of the bathroom, and the other is attached to an appropriate position of the kitchen which is a living space.
Further, from the state of FIG. 15, as shown in the state of the valve of FIG. 13 to FIG. 14, the valve unit 12 composed of the member and the fixing member 9 is connected and fixed inside the drain port 1, so Construction of the remote-operated drain plug device is completed.

The remote-operated drain plug device of the third embodiment attached as described above operates as follows. First, as shown in FIG. 13, the valve member 2 is lowered and the drain port 1 is closed. In this state, when the operation unit 3 is operated and the first magnet 5c is energized, a magnetic field is generated in the first magnet 5c, repelling the second magnet 5d of the support shaft 4, and the holding mechanism unit The support shaft 4 is pushed upward, and the thrust lock mechanism operates. Then, when the energization of the first magnet 5c is canceled by the receiving unit 10 and the magnetic field disappears, the valve member 2 is fixed in the raised state, the state shown in FIG. Waste water is discharged.
When the operation unit 3 is operated again from this state and the first magnet 5c is energized, a magnetic field is generated again in the first magnet 5c, repelling the second magnet 5d of the support shaft 4, and the holding mechanism unit. The support shaft 4 is pushed upward to operate the thrust lock mechanism. After that, the energization of the first magnet 5c is released by the receiving unit 10, whereby the support shaft 4 is released and the valve member 2 is lowered to return to the state of FIG. Thereafter, by repeating this process, the drain port 1 can be freely opened / closed remotely. In order to operate as described above, in this embodiment, a combination of both the first magnet 5c and the second magnet 5d constitutes the electric part.

The remote-operated drain plug device of the third embodiment has the following effects.
The remote-operated drain plug device of the third embodiment can be opened and closed by a repulsion caused by energization of the first magnet 5c and a thrust lock mechanism that is a holding mechanism. Since no human power is used, the drain port 1 can be easily opened and closed even if the user does not have much arm strength or the like.
In the remote-operated drain plug device of the third embodiment, the first magnet 5c is energized only for a few seconds when the opening / closing operation occurs, and is energized to maintain the open or closed state. There is no need to do. Therefore, power consumption due to energization in the operation is very small, and the burden on the device can be reduced.
In the remote-operated drain plug device, the fixed member 9 and the valve member 2 including the first magnet 5c and the holding mechanism which are electric parts are configured as a valve unit 12 which is physically independent from the operation part 3. Therefore, when performing maintenance such as member repair or battery replacement, the valve unit 12 can be easily removed and replaced as it is. Of course, maintenance can be easily performed because only partial repairs such as wiring can be taken out from the narrow drainage port 1 and performed at hand.
Moreover, in the said 3rd Example, the valve unit 12 and the operation part 3 which consist of the valve member 2 and the fixing member 9 are provided as a member of a water heater. In the conventional remote-operated drain plug device, as in the first conventional example, the operation mechanism 3 and the holding mechanism for moving the valve member 2 up and down are physically connected by a release wire or the like. It was necessary to carry out according to the construction of the drainage pipe, and there was nothing other than handling all of the remote-operated drainage plug devices as a component of drainage equipment.
Further, as in the first embodiment and the second embodiment, even if the holding mechanism portion and the operation portion 3 are not directly connected, the inside and the outside of the drain pipe such as the insertion hole 8b provided in the elbow pipe 8 are penetrated. If there is a configuration to do so, it is necessary to carry out construction work in conjunction with the construction of drainage equipment because of the necessity of wiring etc. to ensure the water tightness of the part concerned, and all of the remotely operated drainage plug devices are used for drainage There was nothing other than treating it as a member of the equipment.
On the other hand, in the third embodiment of the present invention, the construction is completed by simply fixing the valve unit 12 composed of the fixing member 9 and the valve member 2 to the drain port 1 that has already been constructed. The valve unit 12 is fixed because there is no connection / fixing portion that is required to maintain a watertight state unless there is a maintenance / repair operation. If the connection structure is standardized, it is possible to easily connect and fix even products from different manufacturers. As a result, the valve unit 12 and the operation unit 3 can be provided as a member of a water heater (or a hot water supply device), not a drainage device, and can be constructed.
Then, by providing the valve unit 12 and the operation unit 3 including the valve member 2 and the fixing member 9 as one member of a water heater (or a hot water supply device), a provider such as a manufacturer of a water heater and a drain pipe is provided. Even in a different case, the operation unit 3 of the remote-operated drain plug device was incorporated into the operation unit 3 of the water heater (or hot water supply device) and could be handled as an integrated operation unit 3.
Thereby, for example, a series of operations of closing the drain outlet 1 of the bathtub B and hot water filling could be performed all from a place away from the bathroom.
In addition, the drainage port 1 is opened from the operation unit 3 (support shaft 4 is raised) or closed (support shaft 4 is lowered). Therefore, the state of the drainage port 1 is confirmed also from the operation unit 3 provided in a place where the drainage port 1 of the bathtub B cannot be directly seen, or the operation of the water heater and the opening / closing operation of the drainage port 1 are interlocked. Even if hot water supply / water supply operation is performed, when it is detected that the drain outlet 1 is open, the fact that the drain outlet 1 is open is displayed and hot water / water supply is not performed in the bathtub B. It was possible to prevent hot water and water from being supplied to the bathtub B by mistake.

The fourth embodiment of the present invention will be described below with reference to the drawings. The remote control type drain plug device of the fourth embodiment of the present invention shown in FIGS. 17 to 18 has the same configuration as the remote control type drain plug device described in paragraph 0031 except for the fixing member 9 described below.

The holding mechanism portion has the same configuration as the thrust lock mechanism of the first embodiment described in paragraph 0023, and a sensor is provided between the side surface of the support shaft 4 and the thrust lock mechanism. The height position of the support shaft 4 is detected to detect whether the drain port 1 is in an open state or a closed state, and the data is sent to the operation unit 3. Furthermore, an artificial muscle portion 5e made of an artificial muscle which is an electric portion having the following configuration is provided below the support shaft 4.
The artificial muscle portion 5e is a member made of an artificial muscle using a polymer material that is bent when energized. Artificial muscles that bend when energized are known in JP2009-191117, JP2009-46649, JP11-169394, JP11-169393, and the like. In this embodiment, a plurality of artificial muscles are stacked, and the ends thereof are fixed to each other so as to extend upward as shown in FIG. 19 from the state shown in FIG. 20 where no current is supplied. Thus, the support shaft 4 is pushed upward to operate the thrust lock mechanism.
The receiving unit 10 is a member in which wiring is performed to the artificial muscle unit 5e which is an electric unit in the fixing member 9. The receiving unit 10 receives an operation from the operation unit 3, and a power source provided in the fixing member 9 according to the operation. The electric power supplied from the unit 11 is supplied to the artificial muscle unit 5e. In the receiving unit 10, when the operation radio wave from the operation unit 3 is received and the artificial muscle unit 5 e is energized, the artificial muscle unit 5 e is energized for several seconds in advance, and the support shaft 4 is Energization is automatically terminated after a sufficient time for the thrust lock mechanism to move up enough to operate. When the radio wave of the operation unit 3 is received and energization is started, even if the operation unit 3 is additionally operated until the set energization time elapses and the radio wave of the operation is received, the reception unit At 10, it is treated as invalid. After the energization time has elapsed, the receiving unit 10 receives the operation radio wave transmitted from the operation unit 3 again and supplies power from the power supply unit 11 to the artificial muscle unit 5e to operate the artificial muscle unit 5e. Is possible.
The power supply unit 11 is a member provided with a battery therein, and supplies power to the receiving unit 10.

The remote control type drain plug device of the fourth embodiment of the present invention described above is constructed and attached as follows. After the drain plug body 7 is inserted into the mounting port of the bathtub B from above, the female screw of the elbow pipe 8 is screwed into the male screw of the drain cock body 7, and the lower surface of the flange 7a of the drain plug body 7 and the upper edge of the elbow pipe 8 And fix the peripheral edge of the mounting opening. Further, the discharge port 8a is connected to a pipe on the sewage side.
This completes the construction on the drain pipe side.
After that, as construction work on the water heater side, along with the construction of the water heater, one of the operation units 3 is attached in the vicinity of the bathroom, and the other is attached to an appropriate position of the kitchen which is a living space.
Further, by connecting and fixing the valve unit 12 including the member and the fixing member 9 to the inside of the drain port 1, the construction of the remote control type drain plug device to the bathtub B which is a tank body is completed.

The remote control type drain plug device of the fourth embodiment attached as described above operates as follows. First, as shown in FIG. 17, the valve member 2 is lowered and the drain port 1 is closed. At this time, the artificial muscle is in a folded state. In this state, when the operation unit 3 is operated and the artificial muscle unit 5e, which is an electric unit, is energized, each layer of the artificial muscle unit 5e bends and becomes a state as shown in FIG. The support shaft 4 is pushed upward to operate the thrust lock mechanism.
When the operation unit 3 is operated again from this state and power is supplied to the artificial muscle part 5e which is an electric part, the artificial muscle part 5e is bent again, and the support shaft 4 of the holding mechanism part is pushed upward, and the thrust is thrust. The lock mechanism operates. After that, the energization of the artificial muscle 5e is released by the receiving unit 10, whereby the support shaft 4 is released, and the valve member 2 is lowered to return to the state of FIG. Thereafter, by repeating this process, the drain port 1 can be freely opened / closed remotely.

  The remote-operated drain plug device of the fourth embodiment has the same effects as the third embodiment of paragraph 0034. Further, unlike the third embodiment, the fourth embodiment does not use magnetic force, so that metal pieces or the like adhere to the support shaft 4 or the drain port 1 or the generation of scale derived from iron or the like can be suppressed. Provide effects.

  The embodiments of the present invention are as described above. However, 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 above-described embodiment, the battery is used to supply power. However, the power source 11 of the remote-operated drain plug device may be configured using power derived from a general household outlet. In this case, if the non-contact power source that introduces electricity even if there is no direct contact using the coil and electromagnetic induction, which is introduced in the second conventional example, using the coil and electromagnetic induction, is used in the third embodiment.

Can be.

  In the first embodiment and the second embodiment, as the heat source bodies that act on the shape memory alloy 5a and the bimetal 5b, the heat source bodies themselves generate heat when energized, but instead, a separate heat source body such as a heater is used. It may be provided. Further, for example, the shape memory alloy 5a or the like is generated by the heat generation of the heat source that generates heat by direct energization, for example, the water temperature is raised by a heater that generates heat by energization, and the generated hot water is brought into contact with the shape memory alloy 5a or the bimetal 5b. Instead of deforming the bimetal 5b, the heat source body heat may be transmitted to another material, and the shape memory alloy 5a or the bimetal 5b may be indirectly heated to cause deformation.

  Moreover, in the said 3rd Example and 4th Example, although the drain outlet 1 of the bathtub B is opening, even if it performs operation of hot water supply / water supply of the bathtub B, it is comprised so that operation may be invalidated. Instead of this, the drain outlet 1 may be automatically closed when the hot water supply / water supply operation of the bathtub B is performed when the drain outlet 1 of the bathtub B is open.
