Description

  The present invention relates to a drain plug device, and more particularly to a drain plug device with improved hygiene and design.

Conventionally, in order to treat the drainage generated in the tank body such as a bathtub or a wash bowl, a drain plug device is formed on the bottom surface of the tank body to form a drain port, and the drainage pipe is connected to the sewage through the drain pipe. The method of discharging waste water to the side is widely known.
As an example of a well-known drain plug device, as described in Patent Document 1, it is constructed on the bottom surface of a tank body, and is described below, a bathtub as a tank body, a drain outlet body, and a joint pipe , And a waterproofing packing.
The bathtub is a box that is open at the top, and includes a cylindrical depression on the bottom and a flange that protrudes from the lower end of the depression to the inner diameter side. The inside of the collar part is formed with a mounting opening that penetrates vertically.
The drain port body is a substantially cylindrical member, and a flange portion extending in the outer peripheral direction is provided at the upper end of the cylindrical portion, and a male screw is provided on the outer surface of the cylindrical portion. A drainage channel for allowing drainage to pass therethrough is formed inside the cylindrical portion, and an opening at the upper end portion of the channel is a drainage port through which drainage in the tank flows.
The joint pipe is a pipe connected to the downstream side of the drain port body, and an inner thread of an upstream end portion of the pipe body is provided with a female screw that is screwed with a male screw of the drain port body, and an upper end portion. Is provided with a substantially plate-like plate-like portion extending in the side surface direction. Further, the pipe body is bent in a substantially horizontal direction at an intermediate portion, and its downstream end is connected to a drainage pipe on the sewage side.
The packing is a ring-shaped member having elasticity such as rubber, and in this conventional example, between the flange bottom surface of the drain outlet main body and the top surface of the bathtub collar, and between the plate-shaped top surface of the joint pipe and the bathtub collar. It arrange | positions between part lower surfaces and contact | abuts watertightly.

The drain plug device configured as described above is applied to the tank body as follows.
First, after placing the packing concentrically on the lower surface of the flange part of the drain body, the cylindrical part of the drain plug body is inserted into the mounting port in the recessed part of the tank body, and the bottom surface of the flange part of the drain body Is arranged on the upper surface of the buttock of the bathtub. Thereby, packing is arrange | positioned between the flange part bottom face of a drain outlet main body, and the collar part upper surface of a bathtub.

Next, after inserting an annular packing from the bottom of the bathtub into the drain outlet body, the male thread of the drain outlet body and the female thread of the joint pipe are screwed together, and the bottom surface of the flange part of the drain outlet body and the plate shape of the joint pipe With the upper surface of the part, the flange around the attachment port is sandwiched through the packing, and the drain port body and the joint pipe are connected.
Furthermore, underfloor piping connected to the sewage side is connected to the downstream end of the joint pipe, and the construction of the drain plug device of the conventional example is completed.
At this time, the packing disposed between the bottom surface of the flange portion of the drainage body and the upper surface of the tub part of the bathtub, and between the upper surface of the plate-like part of the joint pipe and the lower surface of the tub part of the bathtub, As a result of being strongly pressed up and down, it comes into watertight contact. For this reason, water flow or water leakage does not occur between the inner diameter side and the outer diameter side of each packing.

In the drain plug device configured as described above, when drainage is generated in the tank body, the drainage passes from the drainage port through the cylindrical portion of the drainage port body and the joint pipe, and is discharged to the sewage side through the underfloor piping.
In addition, during drainage, drainage may pass between the male thread of the drain outlet body and the female thread of the joint pipe and reach the plate part. Since the packing disposed between the lower surfaces prevents water flow and water leakage, drainage or water leakage does not occur outside the piping.

Although not specifically described in Patent Document 1, in order to collect discharged water or drainage in the tank body, when the drain port is closed by the valve member, the valve member is put on the upper surface of the flange portion to close the drain port. In this case, drainage flows between the top surface of the tank body and the outer peripheral surface of the flange portion of the drain body and the recessed portion of the tank body, but between the bottom surface of the flange section of the drain body and the top surface of the tub part of the bathtub. Packing is arranged to prevent water flow or leakage. Thereby, it is possible to prevent the discharged water or drainage accumulated in the tank body from passing between the drain port main body and the drainage pipe from between the flange bottom surface and the bathtub top surface and flowing out downstream.
JP 2012-112229 A

In recent years, proposals have been made to make the gap between the flange portion of the drain outlet main body and the recessed portion of the tank body inconspicuous due to problems in design. If a large groove is formed in this portion, there is a problem in that the design property is poor, and drainage accumulates in the groove portion, and dirt or the like adheres to further deteriorate the design property.
In the case of this conventional example, a portion that is thinner than the flange portion is formed as an annular tongue piece on the outer edge side of the flange portion, and the thin portion is brought into contact with the inner surface of the recessed portion of the tank body. The annular tongue is deformed into a shape along the inner surface of the recessed portion of the tank body, closes the gap between the flange portion of the drain outlet main body and the recessed portion of the tank body, and does not form a groove, and has a highly designed shape.

It is sectional drawing of the drain plug device of a 2nd Example.

A first embodiment of the present invention will be described below with reference to the drawings.
The drain plug device according to the first embodiment of the present invention is a drain port channel which will be described later remotely by operating the operation unit 8 provided at a position away from the drain port 1a by the user of the tank body. It is a drain plug device that can be opened and closed.
The drain plug device of the present embodiment shown in FIGS. 1 to 5 is applied to a wash bowl S as a tank body described below, and includes a drain port body 1 and a joint described below. The pipe 6, the release wire 9, the valve member 4, the operation unit 8, and the overflow pipe 7 are configured.
The wash bowl S is a box that is open at the top, and includes an attachment port H1 for attaching the drain port body 1 on the bottom surface, and an operation portion attachment port H2 for attaching the operation unit 8 on the periphery of the upper opening. Become. Further, an overflow drain port 1a for discharging waste water accumulated in the wash bowl S more than necessary is provided above the side surface of the tank body.
In addition, in the vicinity of the mounting port H1, an inclined surface that is inclined toward the mounting port H1 downward is provided on the inner side surface of the entire circumference, as shown in FIGS. 1 to 4, around the mounting port H1 of the tank body. The depressed portion H10 is provided, and the lower end of the depressed portion H10 is provided with a flange portion H11 that is substantially horizontal and protrudes toward the opening. The angle of the inclined surface is about 60 degrees with respect to the horizontal plane in a cross-sectional view in the side surface direction.
As shown in FIG. 5, the drain port body 1 is a substantially cylindrical member that forms a drain channel inside, and has a drain port 1 a at its upper end and a flange portion that protrudes outward at the upper edge. 2, a lateral hole opening 1 b on the side surface below the flange portion 2, and a male screw on the side surface below the side hole opening 1 b.
Moreover, the flange part 2 of a present Example is formed so that the height width of the flange part 2 may become longer than the width | variety of the flange part bottom face 2b contact | abutted with the collar part H11 in the cross sectional view of a side surface direction. .
More specifically, first, the flange portion upper surface 2a is configured to have an inclination of about 30 degrees in a sectional view that rises toward the outer peripheral side with respect to a horizontal plane in a sectional view in the side surface direction.
Next, the flange bottom surface 2b formed of a substantially horizontal plane protrudes in the horizontal direction from the upper end of the drain outlet main body 1 by the same width as the flange H11 of the tank body in a cross-sectional view in the side surface direction.
Next, the flange portion side surface 2c is a surface having an inclination that linearly connects the outer end portion of the flange portion upper surface 2a and the outer end portion of the flange portion bottom surface 2b in a cross-sectional view in the side surface direction. It is formed so as to substantially match the inclined surface of the inner surface of the depressed portion H10. Precisely, it is formed at an angle slightly smaller than the inclined surface of the inner surface of the recessed portion H10. Therefore, during construction, the outer edge side portion of the flange portion 2 of the flange portion side surface 2c is preferentially recessed. It contacts the inclined surface of the inner surface of the part H10. Since it comprised in this way, the outer-periphery edge part of the flange part 2 necessarily becomes thin, and it has become an elastic part with some elasticity as a result.
With this configuration, the height width of the flange portion 2 (the height width of the flange portion side surface 2c) is longer than the width of the flange portion bottom surface 2b in contact with the flange portion H11 in a side sectional view. It is wide. That is, the flange portion 2 is configured such that the height width of the flange portion 2 is longer than the width of the flange bottom surface 2b in contact with the flange portion H11 in a side sectional view.
Further, a plate nut provided with a female screw that is screwed with a male screw of the drain port main body 1 for fixing the drain port main body 1 to the mounting port H1 of the tank body through an overflow adapter 7b described later is provided.
The overflow pipe 7 is a pipe for joining the drainage from the overflow drainage port 1a provided above the side surface of the tank body to the drainage channel from the drainage port 1a, and is an overflow joint connected to the overflow drainage port 1a 7a, a substantially cylindrical overflow adapter 7b disposed substantially concentrically on the drain port body 1 at the position of the horizontal hole opening 1b of the drain port body 1, a downstream end of the overflow joint 7a, and a side surface of the overflow adapter 7b Hose pipe 7c that communicates with each other. An annular packing P is disposed between the upper surface of the overflow adapter 7b and the bottom surface of the tank body to prevent drainage from flowing out of the flow path between the upper surface of the overflow adapter 7b and the bottom surface of the tank body.
The joint pipe 6 is a member provided with a tubular portion made of a substantially straight cylinder, to which the lower end of the drain outlet body 1 is connected at the upper end thereof. A cap nut having a female screw threadedly engaged with the screw is provided.
Further, the joint pipe 6 is provided with a cylindrical branch pipe portion 6a that holds an end portion of an inner wire 9b of a release wire 9 to be described later on its side surface.
The release wire 9 is a member for transmitting an operation applied to the operation unit 8 to the valve member 4 and is a cylindrical outer tube 9a having rigidity in the axial direction and flexibility in the side surface direction. And an inner wire 9b that slidably moves in the outer tube 9a and that has rigidity in the axial direction and flexibility in the side surface direction. Moreover, the joint member side end part of the inner wire 9b is provided with the raising / lowering member 9c which pushes up the lower end of the valve shaft 4b of the valve member 4 provided rotatably.
The valve member 4 is substantially disc-shaped, and has a valve body 4a that closes a later-described drain outlet channel by contacting the inclined surface of the depression H10, and a cylindrical shape that is suspended from the center of the lower surface of the valve body 4a. It consists of a valve shaft 4b made of a metal rod and eyepieces provided at two locations on the valve shaft 4b.
The valve body 4a is provided with an annular valve packing 5 having a fin portion 5a in the lateral direction below the disk portion. When the valve member 4 is lowered when the construction is completed, the inclined surface of the inner surface of the depressed portion H10 is provided. In addition, the fin portion 5a of the valve packing 5 abuts against the drainage port 1a while including a horizontal element, and prevents drainage from being discharged from the drainage port 1a and from the joint between the flange portion 2 and the inclined surface. To do.
Here, “abutting while including a horizontal element” means that the valve packing 5 is in contact with the inclined surface when the valve member 4 is operating in the vertical direction, and the valve packing 5 and the inclined surface are in contact with each other. The main point is that stress is not generated only in the vertical direction, but also contact and stress in the horizontal direction are also generated.
Moreover, in the structure of this invention, even if it closes only the drain port 1a of the drain port main body 1, the part (water-flow part 3 mentioned later) between the attachment port H1 periphery of a tank body and the flange part 2 of the drain port main body 1 is closed. ) Drains little by little, and it is impossible to prevent water discharge or drainage from the tank.
Therefore, both the flow path from the drain port 1a and the flow path (flow path of the water flow portion 3) from the portion between the peripheral edge of the tank mounting port H1 and the flange portion 2 of the drain port body 1 are provided. In addition, in the present invention, it is described as “drainage channel”, and preventing water discharge or drainage from the tank body is described as “closing the drain channel”. The same applies to the second embodiment.
The drain opening channel is closed when, for example, the above-described valve packing 5 of the valve body 4a is in contact with the inner surface of the depression H10 and covers not only the drain opening 1a but also the periphery thereof.
Further, the valve member 4 is configured such that the valve body 4a of the valve member 4 is substantially the same as the bottom surface of the tank body when the valve member 4 is lowered and the drain outlet channel is closed.
The operation unit 8 includes an operation body 8a that is directly pushed and pulled by a user and an operation unit body 8b that accommodates the operation body 8a so as to be able to move forward and backward.

The drain plug device of the first embodiment configured as described above is applied to the wash bowl S, which is a tank body, as follows.
First, the drain port body 1 is inserted into the mounting port H1 provided on the bottom surface of the wash bowl S without using a watertight connection member such as the packing P, and the lower surface of the flange portion 2 is inserted into the flange of the mounting port H1. The state is in contact with the upper surface of the portion H11.
Thus, since watertight connection was not performed between the flange part H11 of the wash bowl S which is a tank body, and the flange part 2 of the drain port main body 1, from the joint of the wash bowl S and the flange part 2 A water passage portion 3 capable of water passage is formed in a portion between the periphery of the attachment port H1 and the flange portion 2.
In addition, the elastic portion, which is a thin portion of the outer peripheral edge of the flange portion 2, abuts on the inclined surface of the inner surface of the recessed portion H10, and the elastic portion of the flange portion 2 is slightly deformed in accordance with the inclined surface, whereby the flange portion 2 There is almost no gap at the joint between the outer peripheral surface and the depressed portion H10, and the design can be improved.
Next, after connecting the overflow joint 7a to the overflow drain port 1a, the overflow adapter 7b is concentrically arranged on the drain port body 1, and the male screw of the drain port body 1 and the female screw of the plate nut are screwed together. . As a result, the flange bottom surface 2b of the drain port body 1 and the top surface of the plate nut sandwich the flange portion H11 of the mounting port H1 via the overflow adapter 7b and the packing P, and the drain port body 1 becomes the overflow adapter 7b. At the same time, it is attached to the mounting opening H1.
An annular packing P is arranged between the bottom surface of the wash bowl S and the upper surface of the overflow adapter 7b, and between the lower surface of the overflow adapter 7b, the upper surface of the plate nut, and the side surface of the drain outlet main body 1, although the cross-sectional shape is different. By screwing the plate nut with sufficient strength, the packing P is strongly pressed, and the drainage in the channel is prevented from flowing out of the channel.
Next, the operation part main body 8b is fixed to the operation part attachment port H2.
Next, an elevating member 9c is rotatably provided at the end of the inner wire 9b on the drain outlet 1a side of the release wire 9, and the end of the outer tube 9a is disposed in the branch pipe portion 6a of the joint pipe 6. .
Next, the upstream end of the tube portion of the joint pipe 6 is connected to the lower end of the drain port body 1 and the downstream end is connected to a downstream pipe including a trap member and the like in a watertight manner.
Next, the end of the inner wire 9b on the operation unit 8 side of the release wire 9 is connected and fixed to the lower end of the operation body 8a, and the end of the outer tube 9a on the operation unit 8 side is connected and fixed to the lower end of the operation unit main body 8b.
Furthermore, the valve member 4 is arranged from the drain port 1a in the drain port body 1 to the joint part, and the construction of the drain plug device of this embodiment is completed.

Next, the operation of the faucet device of the first embodiment will be described with reference to FIGS.
In the case of using the drain plug device of the first embodiment, as shown in FIG. 2, first, the operation body 8a of the operation section 8 is operated, and the valve member 4 is lowered to the valve body 4a on the inclined surface of the depression H10. The valve packing 5 is in contact, that is, the drain channel is closed.
At this time, the operating body 8a is lowered, and thereby the inner wire 9b is advanced toward the drain port 1a, so that the tip of the elevating member 9c is lowered downward.
In the present embodiment, the upper end of the valve body 4a of the valve member 4 is configured to be substantially the same as the bottom surface of the wash bowl S, which is a tank body, in a state where the drain passage is closed. Good design at time.
When the operation body 8a is pulled up from this state and the elevating member 9c is retracted to the operation portion 8 side via the inner wire 9b, the elevating member 9c rotates around the end of the inner wire 9b, and the elevating member 9c As shown in FIG. 4, the valve body 4a is lifted from the inner surface of the depression H10 by pushing up the valve shaft 4b by abutting the lower end of the valve shaft 4b and further raising the valve body 4a together with the valve shaft 4b. It is spaced apart and the drain outlet channel opens. At this time, the eye plate member 4c is in contact with the inner surface of the drain port main body 1 and functions as a guide so that the valve shaft 4b is not inclined.
When the operation portion 8 is operated again from the state where the drain port channel is opened and the operation body 8a is lowered, the inner wire 9b moves forward to the drain port 1a side, and the elevating member 9c is also accompanied by the inner wire 9b. Return to the position of FIG. As a result, the valve shaft 4b of the valve member 4 loses the support of the elevating member 9c and descends, and the valve shaft 4b and the valve body 4a also descend accordingly, so that the valve member is placed on the inclined surface of the depression H10 of the wash bowl S. When the valve packing 5 of the 4th valve body 4a contacts watertightly, the drain outlet channel is closed again.
Thereafter, by performing a push-pull operation on the operation body 8a, the drain channel can be opened and closed by remote control at the operation unit 8 located away from the drain port 1a.

In the above operation, when there is water discharge or drainage in the wash bowl S in the state in which the valve member 4 is raised and the drain channel is opened, the drain port 1a to the drain port body 1 and the joint pipe 6 are connected. The drainage flows through the pipe, and finally the drainage is discharged from the downstream pipe to the sewage side through the underfloor pipe.
In addition, although the amount of water discharged or drainage flows between the flange portion 2 material and the depression H10 from the joint between the flange portion 2 material and the depression H10, the drainage is sunk with the flange portion 2 material. Passes through the water passage 3 formed between the side of the drain port main body 1 and the mounting port H1 from between the portions H10, flows into the drain port main body 1 from the side hole opening 1b, and connects the joint pipe 6 and the trap pipe. And finally discharged from the underfloor piping to the sewage side.
In the state where the valve member 4 is lowered and the drain outlet channel is closed, when there is water discharge or drainage in the wash bowl S, the water discharge or drainage is accumulated in the wash bowl S which is a tank body. When the water surface reaches the height of the overflow drainage port 1a, the overflow drainage port 1a passes through the overflow joint 7a, the hose pipe 7c, and the overflow adapter 7b, and flows into the drainage port body 1 from the side hole opening 1b. It is finally discharged from the underfloor pipe to the sewage side through the joint pipe 6 and the trap pipe. For this reason, even if water discharge or drainage is continued in the wash bowl S, the water discharge or drainage does not overflow from the upper edge of the wash bowl S.
Further, in this embodiment, since the valve packing 5 of the valve member 4 is in contact with the inclined surface, the watertight performance is high. Since the tank bodies such as the wash bowl S and the bathtub B are larger members than the drain outlet main body 1 etc., it is difficult to form a member with high dimensional accuracy, and the valve packing 5 of the valve member 4 is simply pressed up and down. In order to improve the watertight performance, the valve member 4 needs to be made heavy. In contrast to this, in the configuration in which the valve packing 5 of the valve member 4 is in contact with the depressed portion H10 while including the horizontal element as in the present embodiment, the inclined surface is sufficient if the valve member 4 is lowered. Since the valve packing 5 is pressed inward and outward by this, the valve packing 5 can be pressed with a strong force even if the weight of the valve member 4 is not heavy, and this is a case where the valve packing 5 is in contact with a tank body that cannot have a high dimensional accuracy. However, the watertightness can be easily increased.

Next, a second embodiment of the present invention will be described with reference to the drawings.
The drain plug device of the present embodiment shown in FIG. 6 is constructed in a bathtub B as a tank body, which will be described below. The drain port body 1, the joint pipe 6, and It consists of the valve member 4.
The bathtub B is a box that is open at the top, and includes a mounting port H1 to which the drain port body 1 is attached on the bottom surface.
Further, in the vicinity of the mounting port H1, the periphery of the mounting port H1 of the tank body is a circumferential shape as shown in FIG. 6, and the entire inner surface is inclined toward the mounting port H1 downward. A depressed portion H10 having an inclined surface is provided, and a flange portion H11 that is substantially horizontal and protrudes toward the opening portion is provided at the lower end of the depressed portion H10. The angle of the inclined surface is about 60 degrees with respect to the horizontal plane in a cross-sectional view in the side surface direction.
The drain port body 1 is a substantially cylindrical member that forms a drain channel inside, and has a drain port 1a at its upper end, a flange portion 2 projecting outward at the upper edge, and a lower portion of the flange portion 2 below. Each side has a male screw.
Moreover, the flange part 2 of a present Example is formed so that the height width of the flange part 2 may become longer than the width | variety of the flange part bottom face 2b contact | abutted with the collar part H11 in the cross sectional view of a side surface direction. .
More specifically, first, the flange portion upper surface 2a is configured to have an inclination of about 30 degrees in a sectional view that rises toward the outer peripheral side with respect to a horizontal plane in a sectional view in the side surface direction.
Next, the flange bottom surface 2b formed of a substantially horizontal plane protrudes in the horizontal direction from the upper end of the drain outlet main body 1 by the same width as the flange H11 of the tank body in a cross-sectional view in the side surface direction.
Next, the flange portion side surface 2c is a surface having an inclination that linearly connects the outer end portion of the flange portion upper surface 2a and the outer end portion of the flange portion bottom surface 2b in a cross-sectional view in the side surface direction. It is formed so as to substantially match the inclined surface of the inner surface of the depressed portion H10. Precisely, it is formed at an angle slightly smaller than the inclined surface of the inner surface of the recessed portion H10. Therefore, during construction, the outer edge side portion of the flange portion 2 of the flange portion side surface 2c is preferentially recessed. It contacts the inclined surface of the inner surface of the part H10. Since it comprised in this way, the outer-periphery edge part of the flange part 2 necessarily becomes thin, and it has become an elastic part with some elasticity as a result.
With this configuration, the height width of the flange portion 2 (the height width of the flange portion side surface 2c) is longer than the width of the flange portion bottom surface 2b in contact with the flange portion H11 in a side sectional view. It is wide. That is, the flange portion 2 is configured such that the height width of the flange portion 2 is longer than the width of the flange bottom surface 2b in contact with the flange portion H11 in a side sectional view.
