The remote control type drainage plug device comprised from each above-mentioned member is constructed in the bathtub which is a tank body as follows.
First, the piping on the downstream side is connected and fixed to the discharge port of the elbow member by a method such as adhesion.
Next, the drainage port main body is inserted into the mounting hole of the bathtub, and the lower surface of the flange portion of the drainage port main body is brought into contact with the upper surface of the mounting hole peripheral edge. Further, the female screw of the elbow member is screwed into the male screw of the drainage port main body, and the peripheral edge of the mounting hole is held between the lower surface of the flange portion and the upper surface of the elbow member to fix the drainage port main body to the bath.

The conventional remote-controlled drainage tap device configured as described above has the following problems.
1. In the above-mentioned remote control type drain plug device, the drain port is opened and closed by moving the valve member up and down according to the movement of the inner wire. However, in order to bring the valve member into contact with the contact surface when the valve member is lowered, it is necessary to control the height position of each member at the design stage, and if the design is inappropriate, the valve member Even if it is lowered, the lower limit of the descent is reached before the valve member and the abutment surface abut, and the valve member and the abutment surface may not abut and the drainage port may not be closed. Similarly, when raising the valve member to open the valve member, if the design is improper, the valve member can not be raised sufficiently when raising it, and the width of the gap between the valve body and the contact surface is It may be narrow and drainage performance may deteriorate significantly.
In addition, since it is necessary to control the height position of each member at the design stage as described above, the members of one product may not be diverted to the same member of another product having a different height width. There is a problem of For example, in the remote-controlled drainage device of Patent Document 1, the total height of the drainage body is reduced by 5 mm, and the height position of the projection inside the drainage hole is narrowed by 5 mm with respect to the contact surface accordingly When a new outlet body is manufactured newly, if the conventional valve member and support member are used as they are, the height position of the projection is narrowed by 5 mm with respect to the contact surface, so when the outlet is closed, the valve The member and the contact surface do not contact properly, which may create a gap and cause water leakage. Therefore, it is necessary to newly create a product in which the shape of the support member or the valve member is changed in accordance with the change of the height width of the outlet body.
As described above, when the height width of the member is changed, it is necessary to create a dedicated member for each product.
2. Even if the valve body portion abuts on the abutting surface, if the pressure of the abutment between the valve body portion and the abutting surface is weak, water leakage may occur from the abutting portion. As a method of increasing the pressure of contact between the valve body portion and the contact surface, the weight of the valve member may be increased, or the inner wire may be provided with an elastic material such as a return spring to urge the valve shaft downward. Although the pressure of the contact changes depending on the area of the contact portion, the inclination of the valve stem, etc., the occurrence of water leakage from the contact point can be always prevented stably. Was not limited.
The present invention has been made in view of the above problems, and in the remote control drainage device, the drainage port is opened and closed without affecting the thickness of the tank body and the height dimension of each member of the remote control drainage device. The invention also provides a remote-controlled drain valve device that can be performed more reliably than in the case where the valve member is merely lowered, even when the drainage port is closed. is there.

When it exceeds the value set as a value necessary for closing the outlet in a watertight manner, it is judged that the valve member has closed the outlet, and the descent of the valve member is stopped and the state is maintained. It is a remote control type drain valve device characterized by having constituted .
The term "contact surface" as used herein refers to a surface portion on the bottom surface of the tank body that contacts the valve member in a watertight manner in order to close the drainage port. If it does not have a contact with the valve member, it does not correspond to the contact surface.

The present invention according to claim 2 is characterized in that the drainage port opened in the tank body, the contact surface which contacts the valve member when the drainage port is closed to close the drainage port in a watertight manner, and opens and closes the drainage port by vertical movement. A remotely operated drain valve device comprising a valve member for moving the valve member, an operating portion for vertically moving the valve member, and an operating portion for controlling the opening and closing of the drain port by the valve member by controlling the operation of the operating portion; When the valve member is lifted and the drainage port is opened, the operation portion is closed to perform the closing operation, and when the valve member is lowered to close the drainage port, the detection mechanism for detecting the state of the valve member is provided. , The valve member continued to descend until the detection mechanism detects that the valve member abuts on the contact surface and the drainage port is closed, and the detection mechanism detects the state in which the drainage port is closed. When stopping the lowering of the valve member to maintain its state, pre-discharge outlet The area of contact between the valve member and the contact surface at the time of closing is measured, and the stress for lowering the valve member is measured when the valve member is lowered and the drain port is closed. The pressure at which the valve member and the abutting surface abut is calculated from the area in which the abutting surface abuts and the measured stress for lowering the valve member, and the calculated valve member abuts the surface. When the pressure exceeds the value set as the value necessary for closing the outlet in a watertight manner, it is judged that the valve member has closed the outlet, and the descent of the valve member is stopped and maintained It is comprised so that it may be, It is a remote control type drain valve apparatus.

The present invention according to claim 3 is characterized in that, in the above-mentioned remote control type drainage plug device, when the drainage port is opened from the closing state, the valve member is raised by any height width set in advance from the closing state. A remote controlled drainage device according to paragraph 0005 or 0006, characterized in that the opening of the drainage port is performed .

The present invention according to claim 4 is characterized in that, in the above-mentioned remote-controlled drain valve device, the valve member is lowered when a load exceeding the load generated in normal use is applied to the valve member at the time of opening the drain. A shock absorber for preventing breakage of the remotely operated drain valve device, wherein the descent height width of the valve member by the shock absorber is arbitrarily set to at least open the valve member from the closed state; The remote-controlled flush stop device according to paragraph 0007, which is equal to or greater than the height width of the elevation of the valve member .

The present invention according to claim 5 is characterized in that, in the above-mentioned remote control type drain valve device, when the construction is completed, the operating portion is attached with a fixed height width to the lower surface of the tank body. It is a remote control type drain valve device according to any one of paragraphs 0005 to 0008 .

In the present invention according to claim 1, in the remote control type drain valve device,
The actuating member is provided with an operating portion for moving the valve member up and down by power and a detection mechanism for detecting a state in which the valve member is in contact with the contact surface when the outlet is closed. The descent of the valve member is continued until the detection mechanism detects that the outlet is closed, and the descent of the valve member is stopped and the state is maintained when the detection mechanism detects the state where the outlet is closed. With this configuration, the drainage port can be closed with the valve member always in contact with the contact surface regardless of the descent width of the valve member. In addition, the closing of the outlet is completed by "detecting that the valve member abuts on the contact surface and closing the outlet", and the "height position of the valve member" or "lifting of the valve member""Width" does not have any effect on the confirmation of the closing of the outlet. For this reason, even if it uses the member from which the dimension of the height direction changed, it can be used without any trouble.
In the invention according to claim 3 , it is possible to clarify the specific procedure when opening the drainage port. In the present invention, since the opening and closing of the drainage port is not determined based on the height position with respect to the actuating portion, a method of managing the opening state with such “relative height with respect to closing time” is preferable.
According to the fourth aspect of the present invention, it is possible to clarify the configuration of the shock absorber for preventing the breakage of the remotely operated drainage device. In the present invention, since the height position of the valve member with respect to the actuating portion at the time of opening the drainage port is not managed, the shock absorber is based on such "height width of the valve member at the opening to closing time". It is preferable to design
In the present invention according to claims 1 and 2 , it was possible to show a specific example of the method for detecting the state in which the detection mechanism closes the drainage port. In particular, in the configuration according to claims 1 and 2 , the closing of the drainage port is determined by detecting the pressure of the abutment between the member and the abutment surface, and the valve member and the abutment surface are simply used. Since it is not the structure which judges that "the outlet was closed" only by having "contacted", it is possible to reliably prevent water leakage when the outlet is closed. More specifically, even if the valve member and the contact surface are in contact with each other, if the pressure of contact between the valve member and the contact surface is low, drainage in the tank body may leak. That is, it may not be sufficient to "close the drainage port so as not to cause water leakage" just by "contacting the valve member and the contact surface". On the other hand, in the present invention according to claim 1 and claim 2 , after "the valve member and the contact surface are in contact with each other", the pressure of the contact between the valve member and the contact surface is It is possible to say that "a water leak or the like does not occur" can be reliably configured by setting the "outlet closed" with the state where the pressure required to close the outlet in a watertight manner is exceeded. .
Further, in the present invention, the relationship between the height position of the actuating portion and the contact surface is different from that of the conventional example in which the opening and closing of the outlet is affected, and the height position of the actuating portion and the contact surface differs in thickness. Even if it changes by attaching to a tank body etc., there is no problem in opening and closing the drainage port. For this reason, when the working portion is attached at a fixed height width to the lower surface of the tank body at the completion of the construction described in claim 5 , that is, the height of the contact surface and the working portion depending on the thickness of the tank body Even when the relationship between the positions changes, it can be suitably used.

The valve stem portion 8 is configured by combining two cylindrical members in the vertical direction, and a shock absorber using a spring member is incorporated. This shock absorber does not operate against the load due to the water pressure when the bathtub B is full, but a higher load, specifically, a load that causes damage to members such as a person stepping on it, occurs The upper cylindrical portion is housed in the lower cylindrical portion, so that the descent width more than the rising width of the valve member 3 at the time of opening the drainage port 1, in this embodiment, can be lowered by about 15 mm. ing. For energizing the motor and transmitting pressure data sent from the valve member 3, the connection point between the second contact 4 a of the operating unit 4 and the second terminal 7 a of the elbow member 7 is used. To be done.
Further, the actuating portion 4 is inserted into the elbow member 7 from the drainage port 1 and the second contact 4 a of the actuating portion 4 and the second terminal 7 a of the elbow member 7 are connected to each other. It can be detachably connected and fixed to the

The operation unit 5 of the present embodiment receives supply of electric power from a household power source using an outlet or the like, appropriately energizes the operation unit 4 and the pressure sensor S, etc., and also operates the operation unit 4 and the pressure sensor S etc. A control board for operating the members appropriately is provided.
In addition, the operation unit 5 includes a touch panel, and by performing a specific operation on the touch panel, the opening and closing of the drainage port 1 and an operation 2 to be described later can be instructed. The touch panel portion is attached flush with the surface near the upper edge of the bathtub B to which the operation unit 5 is attached, and also displays the open / close state of the drainage port 1 with the color tone of light emission It is configured.
In addition, the operation unit 4 can perform at least the following four operations by control such as control of energization / transmission of data from a control board provided in the operation unit 5.
Operation 1. By stopping the energization, the valve stem 8 is maintained at the current height position substantially without being affected by the amount of water in the bathtub B, the flow of drainage, and the like. In the present embodiment, applying the stress to the valve stem portion 8 to move the valve stem portion 8 back and forth by the action of the gear incorporated in the working portion 4 is at least the stress generated in the normal use of the bathtub B and the bathroom. It is impossible in the range. Therefore, the stress, pressure and the like applied to the valve member 3 can be maintained only by stopping the energization and stopping the motor.
Operation 2. The valve stem 8 is protruded to the maximum height position.
Operation 3. The valve shaft portion 8 is lowered until the numerical value of the pressure at the contact point between the valve member 3 and the contact surface 2 obtained by the pressure sensor S reaches the preset value which is regarded as the water stop completion. Let
Operation 4. When the drainage port 1 is closed, the valve stem 8 is raised from the current height position by the height width required to open the drainage port 1 and drain properly from the current height position. Specifically, in this embodiment, when the operation 4 is instructed, the valve stem 8 is raised by 10 mm.
These operations perform operations corresponding to the operations by performing operations set in advance in the operation unit 5.

The remote control type drainage apparatus comprised from each above-described member is constructed by the bathtub B which is a tank body as follows. Although not described in detail, the connection points of the respective members, and some electronic devices and the like are adhered / connected in a watertight manner using an adhesive, packing or the like so as not to cause water leakage and the like.
First, at the factory, the actuating portion 4 is inserted from the opening provided with the male screw of the elbow member 7, the actuating portion 4 is inserted into the storage portion 7c of the elbow member 7, the second contact 4a of the actuating portion 4 and the elbow member After the second terminal 7a of 7 is connected, the connection is fixed.
In this state, each member is carried to the construction site.
Next, after connecting and fixing the piping on the downstream side to the discharge port 7b of the elbow member 7 by bonding or the like, the drainage port main body 6 is inserted into the mounting hole of the bathtub B, and the flange portion of the drainage port main body 6 6a lower surface is brought into contact with the upper surface of the mounting hole rim.
Further, the female screw of the elbow member 7 is screwed into the male screw of the drainage port main body 6, and the peripheral edge of the mounting hole is held between the lower surface of the flange portion 6a and the upper surface of the elbow member 7 to fix the drainage port main body 6 to the tub B.
The attachment position of the elbow member 7 in the height direction is fixed to the bottom surface of the bathtub B by attaching the elbow member 7 to the bottom surface of the bathtub B as described above. It will be attached. And since the operation part 4 is attached to the elbow member 7 at a fixed position including the height direction, when the construction is completed, the operation part 4 is against the lower surface of the bottom of the bathtub B which is a tank body. It will be attached at a fixed height position (height width). On the other hand, since the thickness of the tank body such as the bathtub B is different for each tank body, the height width from the contact surface 2 to the working part 4 which is a fixed height position with respect to the upper surface side of the bottom surface of the tank body is It will differ depending on the difference in thickness of the tank body from body to body.
Next, the operation unit 5 is attached near the upper edge of the bathtub B, and the operation unit 5 and the second terminal 7 a of the elbow member 7 are connected by wiring. As a result, it becomes possible to energize the operation unit 4 from the operation unit 5 and to transmit pressure data from the valve member 3 to the operation unit 5 from the valve member 3 and control the operation of the operation unit 4 from the operation unit 5 The transmission and reception of pressure data and operation data can be performed by transmitting digitized data.
Furthermore, the first contact 3 d of the fitting portion 3 c of the valve member 3 and the first terminal 8 a of the valve stem 8 are connected to each other, and the fitting portion 3 c of the valve member 3 is connected to the valve stem 8. The fitting is completed, and the construction of the remote-controlled drainage device of this embodiment is completed.
When the valve stem portion 8 does not project sufficiently from the drain port 1 when the valve member 3 and the valve stem portion 8 are fitted and connected, the operation portion may be difficult. By adding the operation to 5 and performing the operation 2 of paragraph 0013 to sufficiently project the valve stem portion 8 with respect to the drainage port 1, the fitting connection becomes possible.
As described above, the construction of the remote control drainage device of the present embodiment is completed.

Hereinafter, the operation of the remotely-controlled flush drain apparatus according to the first embodiment will be described.
In the case of using the remote-controlled drainage device according to the first embodiment, as shown in FIG. 1, first, the operation unit 5 is operated to make the drainage port 1 closed.
From this state, when the operation of instructing the opening of the drainage port 1 to the operation unit 5 is performed, the operating unit 4 raises the valve stem 8 by 10 mm from the state of closing the drainage port 1 and standing still. Operate the motor.
As described above, since the motor incorporated in the working unit 4 is a motor called a stepping motor that can control the number of rotations, the elevation height of the valve stem 8 per motor rotation is input in advance, By computing, the valve stem 8 is raised by 10 mm without excess and deficiency from the stationary state in which the drainage port 1 is closed, and the state shown in FIG. The fact that the member 3 is separated from the contact surface 2 can be confirmed by the pressure sensor S of the valve member 3 losing the contact pressure and not detecting it. Further, in the present embodiment, the valve shaft 8 and the valve member 3 fitted with the valve shaft 8 are not in operation even if the motor etc. is not energized by the action of the gear incorporated in the actuating portion 4. In this case, the valve stem 8 can be maintained in the raised state.
Thus, the drain port 1 can be opened by the valve member 3 moving up and the contact surface 2 and the water blocking member 3b separating from each other. When drainage (bath water) is accumulated in the bathtub B, it can be discharged from the drainage port 1 to the piping on the sewage side from the drainage port 7 b via the inside of the drainage port main body 6 and the inside of the elbow member 7.
From this state, when the operation for instructing the closing of the drainage port 1 to the operation unit 5 is performed, the actuating unit 4 lowers the valve stem 8 and the valve member 3 fitted to the valve stem 8. When the valve stem portion 8 is fully lowered and the water blocking member 3b of the valve member 3 abuts on the contact surface 2 of the outlet body 6, the pressure sensor S detects the contact between the water blocking member 3b and the contact surface 2 Detect contact pressure. Even if the water blocking member 3b abuts on the contact surface 2, the valve shaft is until the pressure of the contact between the two detected by the pressure sensor S reaches a preset value for securing water tightness. The portion 8 continues to descend, and naturally the pressure of the abutment between the water blocking member 3b and the abutment surface 2 also continues to rise. When the value detected by the pressure sensor S exceeds the value set in advance for securing the water tightness, the operation unit 4 terminates the energization to the motor. As with the opening of the drainage port 1, the valve incorporated in the valve stem 8 and the valve stem 8 is operated by the action of the gear incorporated in the actuating part 4 without energizing the motor etc. Keep it stopped. In this case, after the pressure of the contact between the water blocking member 3b and the contact surface 2 exceeds the preset value for securing the water tightness, the valve member 3 drains the drainage port 1 The closed state can be maintained.
As described above, not only "the drainage port 1 is closed by the valve member 3" but also "the pressure of the contact between the water blocking member 3b and the contact surface 2 set in advance, ensures water tightness". Therefore, the pressure of contact between the valve member 3 and the contact surface 2 is insufficient due to the fact that the drainage port 1 is closed by the valve member 3 after exceeding the value for the valve member 3 and the contact surface 2 The occurrence of water leakage can be reliably prevented without the occurrence of water leakage from between.
Further, in the present embodiment, the closing state of the drainage port 1 has a state where the contact state between the valve member 3 and the contact surface 2 is detected by the detection mechanism regardless of the height width from the contact surface 2 to the actuating portion 4. Since the pressure sensor S detects the pressure, as described in paragraph 0014, even if the height width from the contact surface 2 to the actuating portion 4 is different for each bathtub B, the drainage port does not have any problem. 1 can be opened and closed.
Thereafter, the drainage port 1 can be freely opened and closed by remote control by repeating the above operation.

In the remote control type drain valve device according to the first embodiment, the user of the bathtub B accidentally makes the valve member 3 when the drain port 1 is opened, that is, when the valve stem 8 and the valve member 3 are lifted. When stress exceeding normal use acts on the valve stem 8 etc. by stepping on the valve stem portion, etc., the shock absorber of the valve stem 8 acts and the valve stem 8 shrinks without the actuating portion 4 operating. Temporarily, as shown in FIG. 4, the valve member 3 is lowered to a position where the valve member 3 abuts on the contact surface 2 of the outlet body 6, and the valve stem 8 and the valve member 3 are damaged. To prevent that.
The reduced width of the shock absorber is 15 mm and exceeds 10 mm, which is the rising width of the valve stem 8 for opening the outlet 1, so that the valve member 3 reliably contacts the outlet 6 The valve member 3 can be lowered to a position where it abuts on 2 and damage to the member can be prevented.

  In the above-mentioned remote control type drain valve device, when any failure occurs in the operating portion 4, after removing the valve member 3 from the valve stem portion 8, release the connection and fixation of the operating portion 4 and the elbow member 7 from the drain port 1. Take out the malfunctioning operating part 4 from the drainage port 1 and further insert a new operating part 4 again from the drainage port 1 into the inside of the elbow member 7, and the second contact 4 a of the operating part 4 and the second contact of the elbow member 7 After connection with the terminal 7a of the terminal, the connection is fixed. Furthermore, the first contact 3 d of the fitting portion 3 c of the valve member 3 and the first terminal 8 a of the valve stem 8 are connected to each other, and the fitting portion 3 c of the valve member 3 is connected to the valve stem 8. It can be fitted to repair a fault that has occurred in the remotely operated drainage device.

  As described above, the remote-control type drainage plug device of the first embodiment performs closing based on the value detected by the pressure sensor S when the drainage port 1 is closed, and when the drainage port 1 is open, the drainage port 1 In order to determine the height width for raising the valve member 3 based on the closed state, the actuating portion 4 is a member other than the member having the contact surface 2 (in the present embodiment, the outlet main body 6 having the contact surface 2 If the relationship between the height position of the contact surface 2 and the actuating portion 4 varies with the thickness of the peripheral edge of the mounting hole of the bathtub B, which differs from one bathtub to the other, the The drainage port 1 can be opened and closed without any adjustment and without any trouble.

It consists of a valve stem portion 8 and a second contact 4 a connected to the second terminal 7 a of the elbow member 7.
The valve stem portion 8 is configured by combining two cylindrical members in the vertical direction, and a shock absorber using a spring member is incorporated. This shock absorber does not operate against the load due to the water pressure when the bathtub B is full, but a higher load, specifically, a load that causes damage to members such as a person stepping on it, occurs The upper cylindrical portion is housed in the lower cylindrical portion, so that the descent width more than the rising width of the valve member 3 at the time of opening the drainage port 1, in this embodiment, can be lowered by about 15 mm. ing.
The energization for operating the motor of the operating unit 4 is performed via the connection point between the second contact 4 a of the operating unit 4 and the second terminal 7 a of the elbow member 7.
Further, the actuating portion 4 is inserted into the elbow member 7 from the drainage port 1 and the second contact 4 a of the actuating portion 4 and the second terminal 7 a of the elbow member 7 are connected to each other. It can be detachably connected and fixed to the
Furthermore, the operation unit 4 includes a stress sensor that detects a stress when the valve stem 8 is lowered when the valve stem 8 is lowered, that is, when the outlet 1 is closed.
The elbow member 7 is a drainage member provided with an opening for connection with another pipe at the upper side and the side, and the flange portion 6a that protrudes outward is formed at the upper opening periphery, and the other side is It comprises an outlet 7b for connecting a drainage pipe, respectively. The flange portion 6a is provided with a through hole at a position corresponding to the screw hole of the base portion, and the inner diameter of the upper opening substantially matches the outer diameter of the cylindrical portion of the base portion. It can be inserted into the upper opening of 7 and used as a guide structure for positioning and as a contact surface for securing water tightness at the time of construction.

The storage portion 7c is provided with a second contact 4a connected to the second terminal 7a provided in the actuating portion 4, and from the wire connected to the second contact 4a, the operation portion In 5, an energization for operating the motor and transmission of a value of stress acting on the valve stem 8 are performed.
The operation unit 5 is a member that operates the opening and closing of the drainage port 1 and is a member that is disposed near the upper edge of the bathtub B and that operates the opening and closing of the drainage port 1. The operation unit 5 of the present embodiment receives supply of electric power from a household power source using an outlet or the like, appropriately energizes the operation unit 4 and the stress sensor, etc., as well as various members such as the operation unit 4 and the stress sensor. It comprises a control board for operating properly.
In addition, the operation unit 5 includes a touch panel, and by performing a specific operation on the touch panel, the opening and closing of the drainage port 1 and an operation 2 to be described later can be instructed. The touch panel portion is attached flush with the surface near the upper edge of the bathtub B to which the operation unit 5 is attached, and also displays the open / close state of the drainage port 1 with the color tone of light emission It is configured.
The operation unit 4 can perform at least the following four operations by control such as control of energization / transmission of data from a control board provided in the operation unit 5.
Operation 1. By stopping the energization, the valve stem 8 is maintained at the current height position substantially without being affected by the amount of water in the bathtub B, the flow of drainage, and the like. In the present embodiment, applying the stress to the valve stem portion 8 to move the valve stem portion 8 back and forth by the action of the gear incorporated in the actuating portion 4 is at least the stress applied in normal use of the bathtub B and the bathroom. It is impossible in the range. Therefore, the stress, pressure and the like applied to the valve member 3 can be maintained only by stopping the energization and stopping the motor.
Operation 2. The valve stem 8 is protruded to the maximum height position.
Operation 3. From the stress acting on the valve stem portion 8 obtained from the stress sensor and the area of the contact point between the water blocking member 3b of the valve member 3 and the contact surface 2 which is measured in advance and numerically input The value of the pressure at the contact point between the water blocking member 3b of the valve member 3 and the contact surface 2 is calculated, and the numerical value of the pressure reaches the previously set numerical value of the pressure for stopping water completion. Until the valve stem 8 is lowered. The term "calculate the value of pressure" does not necessarily mean that the value of the pressure at the contact point between the water blocking member 3b of the valve member 3 and the contact surface 2 must be specifically derived in the process of calculation. Indirectly, confirm that the numerical value of the pressure at the contact point between the water blocking member 3b and the contact surface 2 has reached or exceeded the predetermined numerical value of the pressure that is considered to be completely sealed. If you can, you will meet the requirements. For example, "the value of the pressure which is determined as the completion of the termination of the contact between the waterproofing member 3b of the valve member 3 and the contact surface 2 and which is set beforehand" and "the waterproofing member of the valve member 3 measured in advance The product of “the area of the contact point between 3b and the contact surface 2”, that is, “the value of the stress acting on the valve stem 8 necessary for completion of water shut-off” By comparing the value of the stress acting on the portion 8 directly with the value of the pressure at the contact point between the water blocking member 3b of the valve member 3 and the contact surface 2 without direct calculation, It can be checked whether the pressure of the abutment between the member 3 and the abutment surface 2 has reached a preset value of the pressure at which it is determined that the water stop is completed.
Operation 4. When the drainage port 1 is closed, the valve stem 8 is raised from the current height position by the height width required to open the drainage port 1 and drain properly from the current height position. Specifically, in this embodiment, when the operation 4 is instructed, the valve stem 8 is raised by 10 mm.
These operations perform operations corresponding to the operations by performing operations set in advance in the operation unit 5.

The remote control type drainage apparatus comprised from each above-described member is constructed by the bathtub B which is a tank body as follows. Although not described in detail, the connection points of the respective members, and some electronic devices and the like are adhered / connected in a watertight manner using an adhesive, packing or the like so as not to cause water leakage and the like.
First, at the factory, the actuating portion 4 is inserted from the opening provided with the male screw of the elbow member 7, the actuating portion 4 is inserted into the storage portion 7c of the elbow member 7, the second contact 4a of the actuating portion 4 and the elbow member After the second terminal 7a of 7 is connected, the connection is fixed.
In this state, each member is carried to the construction site.
Next, after fixing the piping on the downstream side to the discharge port 7b of the elbow member 7 by bonding or the like, the cylindrical portion 9a of the pedestal 9 of the bathtub B is inserted into the opening above the elbow member 7 Abut the lower surface of the flange 9a of the elbow member 7 and the lower surface of the pedestal 9 of the bottom surface of the bathtub B, which is the periphery of the cylindrical portion 9a, and screw the screw through the through hole of the flange 6a. The elbow member 7 is screwed into the screw hole, and the elbow member 7 is connected and fixed to the lower side of the bottom surface of the bathtub B.
The attachment position of the elbow member 7 in the height direction is a fixed height position with respect to the bottom surface of the bathtub B by attaching the elbow member 7 in contact with the bottom surface of the bathtub B as described above. It will be attached. And since the operation part 4 is attached to the elbow member 7 at a fixed position including the height direction, in the remote-controlled drain valve device of this embodiment, the operation part 4 is a tank when the construction is completed. It will be attached in the height position (height width) fixed with respect to the lower surface of the bottom face of the bathtub B which is a body. On the other hand, since the thickness of the tank body such as the bathtub B is different for each tank body, the height width from the contact surface 2 to the working part 4 which is a fixed height position with respect to the upper surface side of the bottom surface of the tank body is It will differ depending on the difference in thickness of the tank body from body to body.
Next, the operation unit 5 is attached near the upper edge of the bathtub B, and the operation unit 5 and the second terminal 7 a of the elbow member 7 are connected by wiring. As a result, it becomes possible to energize the operation unit 4 from the operation unit 5 and transmit stress data from the valve member 3 to the operation unit 5 from the valve member 3 and control the operation of the operation unit 4 from the operation unit 5 The transmission and reception of stress data and operation data can be performed by transmitting digitized data.
Further, the fitting portion 3c of the valve member 3 is fitted to the valve stem portion 8, and the construction of the remote-controlled drain valve device of this embodiment is completed.
When the valve stem portion 8 does not project sufficiently from the drain port 1 when the valve member 3 and the valve stem portion 8 are fitted and connected, the operation portion may be difficult. By adding the operation to 5 and performing the operation 2 of paragraph 0020, the valve stem 8 is sufficiently protruded with respect to the drainage port 1, and the fitting connection becomes possible.
As described above, the construction of the remote control drainage device of the present embodiment is completed.

Hereinafter, the operation of the remote-controlled flush drain apparatus according to the second embodiment will be described.
In the case of using the remote-controlled drainage device according to the first embodiment, as shown in FIG. 5, first, the operation unit 5 is operated to close the drainage port 1.
In this state, when the operation of instructing the opening of the drainage port 1 to the operation unit 5 is performed, the operating unit 4 raises the valve stem 8 by 10 mm from the state in which the drainage port 1 is closed and stands still. Operate the motor. As described above, since the motor incorporated in the working unit 4 is a motor called a stepping motor which can control the number of rotations, the elevation height of the valve stem 8 per one rotation of the motor is input in advance, By computing, the valve stem portion 8 is raised by 10 mm without excess and deficiency from the stationary state in which the drainage port 1 is closed, and the state shown in FIG. 6 can be maintained and the state can be maintained again. Further, in the present embodiment, the valve shaft 8 and the valve member 3 fitted with the valve shaft 8 are not in operation even if the motor etc. is not energized by the action of the gear incorporated in the actuating portion 4. In this case, the valve stem 8 can be maintained in the raised state.
Thus, the drain port 1 can be opened by the valve member 3 moving up and the contact surface 2 and the water blocking member 3b separating from each other. When drainage (bath water) is accumulated in the bathtub B, it can be discharged from the drainage port 1 to the piping on the sewage side from the drainage port 7 b through the inside of the elbow member 7.
From this state, when the operation for instructing the closing of the drainage port 1 to the operation unit 5 is performed, the actuating unit 4 lowers the valve stem 8 and the valve member 3 fitted to the valve stem 8. A stress sensor that detects the stress acting on the valve stem 8 when the valve stem 8 fully descends and the water blocking member 3b of the valve member 3 abuts on the contact surface 2 of the outlet body 6 Detects the stress acting on the valve stem 8. When stress is applied in the direction of lowering the valve stem 8 further while the water blocking member 3b and the contact surface 2 are in contact, stress acts on the valve stem 8 to be lowered and the stress sensor The value of the stress acting on the valve stem 8 to be detected is increased.
The pressure of the contact between the water blocking member 3b and the contact surface 2 calculated in advance based on the value of this stress and the value of the area where the water blocking member 3b and the contact surface 2 are in contact The valve stem 8 continues to descend until the set value for securing water tightness is reached, and naturally the stress acting on the valve stem 8 also continues to rise. When the value of the pressure of contact between the water blocking member 3b and the contact surface 2 detected and calculated by the stress sensor exceeds the value for securing water tightness set in advance, the actuating portion 4 operates the motor Turn off the power. As with the opening of the drainage port 1, the valve incorporated in the valve stem 8 and the valve stem 8 is operated by the action of the gear incorporated in the actuating part 4 without energizing the motor etc. Keep it stopped. In this case, after the pressure of the contact between the water blocking member 3b and the contact surface 2 exceeds the preset value for securing the water tightness, the valve member 3 drains the drainage port 1 The closed state can be maintained.
Thus, the value of the stress acting on the valve stem 8 from the stress sensor and the water blocking member 3b and the contact surface 2 are not only simply "the drain 1 is closed by the valve member 3". The pressure of the contact between the water blocking member 3b and the contact surface 2 calculated from the area of the surface in contact with the water exceeds the preset value for securing water tightness, and the drainage port 1 Is closed by the valve member 3, the pressure of the contact between the valve member 3 and the contact surface 2 is insufficient, and water does not form between the valve member 3 and the contact surface 2 without fail. Water leakage can be prevented.
Further, in the present embodiment, regardless of the height width from the contact surface 2 to the actuating portion 4, the state of contact between the valve member 3 and the contact surface 2 is detected by the stress sensor which is a detection mechanism. Because of this, as described in paragraph 0020, even if the height width from the contact surface 2 to the actuating portion 4 is different for each bathtub B, the drainage port 1 can be opened and closed without any problem.
Thereafter, the drainage port 1 can be freely opened and closed by remote control by repeating the above operation.

Even if the user of the bathtub B accidentally steps on the valve member 3 with the drainage port 1 opened, the remote-controlled drain valve device of the second embodiment described in the paragraph 00016 As in the case of the remote-controlled drain valve device, the shock absorber functions to prevent the valve stem 8 from contracting as shown in FIG. 8 to prevent the valve stem 8 and the valve member 3 from being damaged.
Further, in the remote-controlled drain valve device according to the second embodiment, even when any failure occurs in the operating unit 4, drainage is carried out as in the case of the remote-controlled drain valve device according to the first embodiment described in paragraph 00017. The operation part 4 can be replaced only by the work from the mouth 1, and the failure can be repaired without any trouble.

  As described above, the remote-control type drainage plug device of the second embodiment performs closing based on the value detected by the stress sensor when the drainage port 1 is closed, and closes the drainage port 1 when the drainage port 1 is open. In order to determine the height width for raising the valve member 3 on the basis of the state at the time of operation, the actuating portion 4 is a member other than the member having the contact surface 2 (in this embodiment, it is not the bathtub B having the contact surface 2 but an elbow Even if the relationship between the height position of the contact surface 2 and the actuating portion 4 is different depending on the bathtub depending on the thickness of the periphery of the mounting hole of the bathtub B which is different for each bathtub The drainage port 1 can be opened and closed without any trouble.

Although the embodiment of the present invention is as described above, the present invention is not limited to the above embodiment, and can be freely modified without departing from the scope of the present invention.
For example, although the first embodiment and the second embodiment all adopt the bathtub B as the tank body, the present invention is not limited to the above embodiment, and the tank body is a wash basin of the wash basin. You may use for any tank bodies, such as a sink of a sink.
Further, in the first embodiment and the second embodiment, as the detection mechanism, the pressure of the contact between the valve member 3 and the contact surface 2 is detected directly or indirectly to determine whether the drainage port 1 is opened or closed. However, the present invention is not limited to the above embodiment, and in the state where the valve member 3 is lifted and the drainage port 1 is opened, the operation part 5 is closed and the valve member 3 is lowered. When the drainage port 1 is closed, any detection mechanism may be used as long as it detects a state in which the valve member 3 abuts on the contact surface 2.
As another method, the motion sensor for detecting the movement of the valve stem portion 8 is provided, and the motor of the actuating portion 4 is operated in advance with “the contact area between the water blocking member 3b and the contact surface 2 and the water blocking member Stress required for the water blocking member 3b and the contact surface 2 to be in watertight contact, which is obtained from the pressure of the contact required to ensure the water tightness of the contact point of the contact surface 3b and the contact surface 2 " The valve shaft 8 and so on can not be lowered because the valve member 8 abuts on the contact surface 2 when the water outlet 1 is closed (at this time, it abuts on the water blocking member 3b). The pressure of the contact of the surface 2 reaches the pressure of the contact required to ensure the watertightness of the contact point), and the operation sensor detects that the valve member 3 is drained. The mouth 1 may be configured to be closed in a watertight manner.
Besides, a structure in which a contact sensor is simply provided on one of the contact surface 2 and the valve member 3 to detect a state in which the valve member 3 is in contact with the contact surface 2, or the contact surface 2 and the valve member 3 A state in which the valve member 3 abuts on the contact surface 2 by using a magnet on one side and a magnetic force detection sensor on the other and the magnetic force detection sensor detecting the magnetic force when the valve member 3 abuts on the contact surface 2 The present invention can also be implemented by a structure or the like for detecting However, when the contact sensor or magnet and the magnetic force detection sensor are used, the pressure of contact between the valve member 3 and the contact surface 2 as in the first embodiment or the second embodiment is detected directly or indirectly. As compared with the configuration in which the opening and closing of the drainage port 1 is determined, the pressure at which the valve member 3 and the abutment surface 2 abut on each other is insufficient, and water leakage may occur. It may be necessary to take measures such as adoption.
Further, in the above embodiment, the actuating portion 4 is a member other than the member having the abutting surface 2, that is, a member in which the relationship between the height position of the abutting surface 2 and the actuating portion 4 changes with the thickness of the tank body. Although provided in the elbow member 7 and configured, the present invention is not limited to this, and a member provided with the contact surface 2 such that the support member described in Patent Document 1 includes the actuating portion 4 The members provided with the actuating portion 4 may be configured as the same member so that the contact surface 2 and the actuating portion 4 always have the same height position relationship regardless of the thickness of the tank body. However, when members such as the support member and the operating portion 4 are disposed in the drainage port 1, these members become obstacles and the cleaning performance and drainage performance deteriorate, so the first embodiment and the second embodiment are implemented. As in the remote-controlled drainage plug device of the example, the member provided with the actuating portion 4 is a member different from the member provided with the contact surface 2 whose height position relationship changes with the thickness of the tank body, If an unnecessary member is not disposed in the drainage port 1, the cleaning performance and drainage performance of the drainage plug device can be improved.
