  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a use mode of a drain trap to which the present invention is applied. Fig.1 (a) has shown the case where it uses for the drainage pipe of what is called wall drainage. FIG.1 (b) has shown the case where it uses for the drainage pipe of what is called floor drainage.

  As shown in FIG. 1, a drain trap 100 is provided between a hot water storage type electric water heater 11 installed on a wall surface W below the basin 10 and a main drain pipe 12 connected to the lower part of the basin 10. To be connected. In FIG. 1A, a part of the drain trap 100 is located between the main drain pipe 12 and the wall surface W and is hidden by the main drain pipe 12.

  The electric water heater 11 is a first-stop water heater that supplies water or hot water to a faucet 13 installed in the wash basin 10.

  The electric water heater 11 is a water supply connected to a sub-drain pipe 14 (not shown in FIG. 1A) that discharges waste water generated by the tip-stop type, and a stop cock 15 protruding from the wall surface W. It has a pipe 16, a power cord 18 connected to a connector 17 disposed on the wall surface W, and a water outlet pipe and a hot water outlet pipe (not shown) connected to the faucet 13.

  One end of the main drain pipe 12 is connected to the lower part of the washbasin 10, and the other end of the main drain pipe 12 is a wall drain in the wall drain shown in FIG. 1 (a) and a floor drain shown in FIG. 1 (b). Are connected to the floor surface F in such a manner that they are inserted into a wall surface W and an attachment member 12a attached to the floor surface F, respectively.

  The drain trap 100 is connected to the sub drain pipe 14 and the main drain pipe 12 below the basin 10.

  FIG. 2 is a perspective view showing the appearance of the drain trap 100 and a part of the internal structure. FIG. 3 is a side sectional view of the drain trap 100. FIG. 4 is an exploded perspective view of the drain trap 100. FIG. 5 is a perspective view showing an example of how the drain trap 100 is used.

  The drain trap 100 is formed in a bottomed cylindrical shape and extends in a direction indicated by an arrow A, and an inflow that is connected to the sub drain pipe 14 and allows drainage from the sub drain pipe 14 to flow into the trap body 20. Part 21 and an outflow part 22 that protrudes from the side of trap body 20 and into which drainage that flows into in trap body 20 from inflow part 21 flows out.

  The drain trap 100 is also connected to the sealing tube 23 disposed in the trap body 20 and extending in the A direction so as to straddle the outflow portion 22 in the A direction, and the outflow portion 22 and the main drain pipe 12. And a connecting joint 24 that guides the waste water flowing out from the main drain pipe 12.

  In addition, the drain trap 100 is normally constructed so that the A direction is a vertical direction.

  As shown in FIG. 4, the drain trap 100 also has a restricting mechanism 50 that allows the connection joint 24 to be connected to the trap body 20 only at a predetermined angle, as shown in FIGS. And a pin 51 for fixing the connection joint 24 in a predetermined state by the mounting.

  The inflow portion 21 is attached to the end of the trap body 20 opposite to the bottom wall 25 in the A direction so as to be rotatable in the B direction around the A direction. Accordingly, the connection direction with the sub-drain pipe 14 can be freely changed.

  The outflow portion 22 is formed at a substantially central portion of the trap body 20 in the A direction so as to protrude in the C direction perpendicular to the A direction from the outer surface of the peripheral wall 26 of the trap body 20.

  The outflow portion 22 has a cylindrical shape, and has openings 34 and 35 at both ends as shown in FIG.

  The outflow portion 22 is also screwed on the outer peripheral surface of the check valve 36 fitted between the middle portion, that is, the opening 34 and the opening 35, and the end portion thereof, that is, the end portion on the opening 35 side. Has a male screw portion 37 for connecting the two.

  The opening 34 communicates with the inner surface, that is, the inner wall of the peripheral wall 26 of the trap body 20, and the opening 35 faces the connection joint 24 side. Therefore, the outflow portion 22 communicates with the space inside and outside the trap body 20 via the check valve 36.

  The check valve 36 is used to prevent the drainage flowing out from the outflow portion 22 to the connection joint 24 from flowing back into the outflow portion 22 when the main drain pipe 12 is clogged.

  The trap body 20 has a peripheral wall 26 of the trap body 20 connected to the end of the side that rotatably supports the inflow portion 21, that is, the end of the trap body 20 that is normally located above the trap body 20. It has the communication port 30 formed in the manner of piercing.

  The trap body 20 is also detachable from the peripheral wall 26 at the end opposite to the side on which the inflow portion 21 is rotatably supported, that is, the end located on the lower side, and forms the bottom wall 25 when mounted. A drain cap 31 is provided.

  The communication port 30 is formed in a portion of the peripheral wall 26 on the side where the outflow portion 22 is formed in the B direction. The communication port 30 includes a plurality of slits 32 formed along the A direction. The slits 32 are juxtaposed in the B direction.

  Each slit 32 has the same position on the end side of the trap body 20 in the A direction, and the position on the bottom wall 25 side in the same direction is appropriately changed. Specifically, the length of the slit 32 in the A direction is the longest corresponding to the center position of the outflow portion 22 in the B direction, and becomes shorter as the distance from the center position becomes longer, and is symmetric in the B direction. Yes.

  Thereby, the space | interval of the edge part position by the side of the bottom wall 25 of the communicating port 30 and the bottom wall 25 is the minimum in the center position of the outflow part 22 in a B direction. The communication port 30 is formed to prevent the wastewater once flowing into the trap body 20 from the inflow portion 21 from flowing back into the inflow portion 21, but having such a shape, Even if the A direction is inclined so that the outflow portion 22 faces upward, such a function can be sufficiently maintained.

  Further, since the width in the B direction is increased upward in the vertical direction, if the rising level of the drainage water in the trap body 20 is small, the amount of drainage from the communication port 30 is small, and the rising degree is large. As the water level gets closer to the inflow portion 21, a larger amount of water is discharged, so that a required amount of water can be obtained.

  The drain cap 31 has a mountain-shaped rectifying projection 33 that protrudes toward the end of the trap body 20 that supports the inflow portion 21. Details of the shape of the rectifying projection 33 will be described later.

  The drain cap 31 is integrated by screwing onto the peripheral wall 26. The drain cap 31 is removed when maintenance is performed, for example, when the drainage in the trap body 20 is frozen or not used for a long time.

  The sealing cylinder 23 has a cylindrical shape and has openings 28 and 29 at both ends. The opening 28 is located on the inflow portion 21 side of the trap body 20, and the opening 29 is located on the bottom wall 25 side of the trap body 20. Thereby, the outflow part 22 is located between the opening 28 and the opening 29 in the A direction.

  The end of the inflow portion 21 side of the sealing cylinder 23 is attached to the inner wall surface of the trap body 20 in a watertight manner, and the diameter thereof decreases toward the bottom wall 25 of the trap body 20. A gap is formed between the end portion of the sealing cylinder 23 on the bottom wall 25 side of the trap body 20 and the bottom wall 25.

  With such a shape and arrangement, a gap is formed between the inner wall surface of the trap body 20 and the outer peripheral surface of the water seal cylinder 23 at the formation position of the outflow portion 22 in the A direction. Moreover, the opening 29 of the water seal cylinder 23 communicates the space inside and outside of the water seal cylinder 23 in the trap body 20 by such shape and arrangement.

  And the sealing cylinder 23 is the outflow part 21 and outflow by the waste_water | drain which flowed in into the trap main body 20 from the inflow part 21 because either or both of the openings 34 and 35 of the outflow part 22 become draft. The part 22 is isolated from each other and sealed. In addition, since A direction makes a perpendicular direction normally, the lower end position of both the openings 34 and 35 becomes draft in this state.

  The end of the sealing cylinder 23 on the bottom wall 25 side of the trap body 20 is the inner wall of the trap body 20 and approaches the inner wall on the side where the outflow portion 22 is disposed in the B direction. The distance from the inner surface of the bottom wall 25 is increased.

  In other words, the end of the sealing cylinder 23 on the bottom wall 25 side of the trap body 20 faces the inner surface of the bottom wall 25 of the trap body 20 and flows out in the B direction on the inner wall of the trap body 20. The shape faces the inner wall on the side where the portion 22 is disposed.

  Such a shape is formed by making the end portion of the sealing cylinder 23 into an obliquely cut state.

  The rectifying projection 33 has a shape of a rotating body having a central axis in the A direction, which protrudes toward the opening 29 and gradually decreases in diameter in the C direction toward the opening 29 at a portion facing the opening 29. In this aspect of gradual reduction, the surface of the rectifying projection 33 forms a curved surface instead of a conical shape.

  Therefore, the surface of the portion of the rectifying projection 33 that faces the opening 29 is smoothly separated from the opening 29 toward the peripheral wall 26. The rectifying projection 33 is formed over the entire inner surface of the bottom wall 25, but may be formed at least at a portion facing the opening 29.

  The drain trap 100 has such a configuration, in particular, the shape and arrangement of the end portion on the opening 29 side of the sealing cylinder 23, and the shape of the rectifying projection 33, so that the drainage that has flowed from the inflow portion 21. However, it is easy to flow from the opening 29 toward the outflow portion 22.

  Specifically, since the opening 29 opens not only in the A direction but also in the B direction toward the arrangement position of the outflow portion 22, the distance between the opening 29 and the inner wall of the trap body 20. Is larger toward the arrangement position side of the outflow part 22 in the B direction, and the area of the drainage flow path at the end on the opening 29 side of the water seal cylinder 23 is larger. It tends to flow toward 22.

  Moreover, in order to make the opening 29 in such a state, the end of the sealing cylinder 23 on the opening 29 side has only to be cut off obliquely, so there is no need to increase the size of the trap body 20 and the drain trap. The increase in size of 100 can be avoided.

  Moreover, since the surface shape of the rectifying projection 33 is smoothly separated from the opening 29 toward the peripheral wall 26, the downward flow of the drainage discharged from the opening 29 is not retained. Since it is guided to the peripheral wall 26 and further directed toward the outflow portion 22 along the peripheral wall 26, the flow of the drainage discharged from the opening 29 is smoothly changed to the upward flow toward the outflow portion 22. The drainage performance is improved.

  The surface shape of the rectifying projection 33 may be a conical shape instead of the curved shape as described above, but such a curved shape is more suitable for such a flow change, and drainage performance is further improved. .

  Since the drainage performance is high, even when a large amount of drainage is performed from the electric water heater 11, the drainage to the main drain pipe 12 is performed satisfactorily. As a case where the amount of drainage from the electric water heater 11 becomes large, for example, a pressure reducing valve normally provided in the electric water heater may be broken.

  The first-stop type electric water heater is usually provided with a relief valve that opens when the water pressure in the hot water tank exceeds a predetermined pressure, and if the pressure reducing valve connected to the water supply side breaks down, Since the water pressure rises to the feed water pressure, the relief valve opens and a large amount of water flows into the drain trap.

  The connection joint 24 is attached to the trap body 20 via the outflow portion 22 and connected to the outflow portion 22 so as to be rotatable in the D direction around the C direction, which is the direction in which the outflow portion 22 is protruded. An elbow pipe 41 as a first pipe having a shape, and a connecting pipe 42 as a second pipe attached to the end of the elbow pipe 41 opposite to the trap body 20.

  The elbow tube 41 is connected to the outflow portion 22 and extends in the C direction, and the first tube portion 43 extends in the E direction substantially perpendicular to the first tube portion 43. And a second pipe portion 44 integrally formed therewith.

  The center position of the outflow portion 22 and the first tube portion 43 in the A direction, the center position of the outflow portion 22 and the first tube portion 43 in the B direction, and the center position of the outflow portion 22 and the first tube portion 43 in the D direction. Are all in agreement with each other.

  The E direction and the A direction may coincide with each other depending on the manner in which the elbow tube 41 is attached to the outflow portion 22 or may be at a right angle. If they match, the drain trap 100 is used for the wall drain shown in FIG. 1 (a), and if it is perpendicular, the drain trap 100 is used for the floor drain shown in FIG. 1 (b). This is the case.

  The elbow pipe 41 is also supported by the first pipe portion 43 so as to be rotatable in the D direction, and has a cap nut 46 having a female screw portion 45 engaged with the male screw portion 37 on its inner peripheral surface, and a second pipe portion 44. And a flange portion 47 which is formed in an oval shape and has a planar shape perpendicular to the E direction. As shown in FIG. 5, the flange portion 47 has a notch 52 at the tip portion on the opposite side to the first tube portion 43 in the C direction.

  The connecting pipe 42 is a member attached to the elbow pipe 41 so as to extend in the F direction which is a direction perpendicular to the E direction.

  The connecting pipe 42 is disposed at the center in the F direction, and is connected to the elbow pipe 41 in such a manner that the distal end of the second pipe 44 is inserted. 48 and fastening means 60 disposed at both ends in the F direction for fastening and connecting the main drain pipe 12.

  The connecting portion 48 has a hole 53 on the upper surface that can communicate with the notch 49.

  The connecting pipe 42 is rotatable in the G direction around the E direction with respect to the second pipe part 44 in the connecting portion 48, and when the F direction is perpendicular to the C direction and the E direction. In addition, the flange portion 47 and the connection portion 48 coincide with each other so that their oval shapes overlap each other, and the notch 52 and the hole 53 are in communication with each other.

  The pin 51 is attached to the connection joint 24 so as to be inserted into the notch 52 and the hole 53 in a state where the notch 52 and the hole 53 communicate with each other, and the second pipe portion 44 rotates with respect to the first pipe portion 43 by the attachment. It functions as a rotation prevention member that prevents this, and fixes the connection joint 24 in this state.

  Each fastening means 60 includes a male screw portion (not shown) screwed at both ends in the F direction of the outer peripheral surface of the connecting pipe 42 main body, and a female screw portion (not shown) screwed to the male screw portion, and is screwed into the male screw portion. A fastening member 62 that is rotatable on the main body of the connecting pipe 42, and a packing 61 that is disposed on each of both ends in the F direction of the main body of the connecting pipe 42 and is compressed by screwing the fastening member 62 into the main body of the connecting pipe 42. have.

  The main body of the connecting pipe 42 is selected to have the same inner diameter as the outer diameter of the main drain pipe 12.

  The fastening member 62 is displaced in the F direction by rotation, and is screwed into the connection pipe 42 main body by rotation in a state where the end of the main drain pipe 12 is inserted into the connection pipe 42 main body. By moving the packing 61 in this manner, the packing 61 is compressed and thickened, and is brought into close contact with the outer periphery of the inserted main drain pipe 12, thereby connecting the main body of the connecting pipe 42 and the main drain pipe 12 in a watertight manner.

  As shown in FIG. 4, the restriction mechanism 50 includes a protrusion 54 protruding from the inner peripheral surface of the outflow portion 22 and an end portion of the first pipe portion 43 on the trap body 20 side. It has three notches 55, 56, 57 that can be fitted.

  In FIG. 4, the check valve 36 is not shown.

  The protrusion 54 protrudes from the inner peripheral surface of the outflow portion 22 at the position closest to the drain cap 31, that is, the lowermost position of the inner peripheral surface of the outflow portion 22 when the A direction faces the vertical direction.

  The notch 55 is formed at the lowest position of the first tube portion 43 when the second tube portion 44 is bent with respect to the first tube portion 43, that is, when the E direction is in the vertical direction. .

  The notches 56 and 57 are respectively formed in two directions perpendicular to the notch 55 in the D direction.

  Therefore, the connection mechanism 24 can be connected to the trap body 20 only by the restriction mechanism 50 in a state where the following predetermined three angles are formed in the D direction.

  The three angles are such that the A direction and the E direction are parallel to each other, and the connection pipe 42 and the drain cap 31 are located on the same side with respect to the outflow part and the first pipe part 43 in the A and E directions. And two directions in which the A direction and the E direction are perpendicular to each other.

  The state in the former direction is the state shown in FIGS. 1A, 1 and 3, and the state in the latter direction is the state shown in FIG.

  When connecting the connecting joint 24 to the trap body 20, the phase in the D direction between the outflow portion 22 and the first pipe portion 43 is set to a desired phase, and the protrusion 54 is cut out of the notches 55, 56, 57. A state in which the connecting joint 24 and the trap body 20 are moved relative to each other in the C direction so that the connection joint 24 and the trap body 20 approach each other, and the protrusion 54 is fitted in the desired notch. Then, the cap nut 46 is rotated in the D direction so that the female screw portion 45 is screwed into the male screw portion 37 and fastened.

  In the drain trap 100 having such a configuration, as described above, the drain trap 100 is usually installed so that the direction A is directed in the vertical direction, and the regulation mechanism 50 is determined depending on whether the drain is wall drain or floor drain. By adjusting the mounting direction of the elbow pipe 41, the F direction is set to be horizontal as shown in FIG. 1 (a) if it is wall drainage, and FIG. 1 (b) if it is floor drainage. As shown in Fig. 2, install it so that it faces vertically.

  As shown in FIG. 5, in the case of wall drainage, the A direction is maintained in the vertical direction even if the pin 51 is removed and the connecting pipe 42 is rotatable with respect to the elbow pipe 41. It is also good.

  If the pin 51 is removed, for example, when maintenance is performed such as cleaning the water supply pipe 16 while the water supply pipe 16 interferes with the drain trap 100, the connecting pipe 42 and the elbow pipe 41 are relatively in the G direction. And the interference between the drain trap 100 and the water supply pipe 16 can be avoided.

  On the other hand, in the case of floor drainage, if the pin 51 is removed, there is an advantage that when the object comes into contact with the drain trap 100, there is an advantage that destruction can be avoided, but the A direction can be inclined with respect to the vertical direction. From the viewpoint of good drainage and sealing water, it is not preferable.

  However, since the communication port 30 is formed in the above-described manner, even if the A direction is inclined from the vertical direction, the sealing performance and the drainage performance are not immediately deteriorated.

  That is, when the communication port 30 is inclined so as to face upward, the connection position of the first pipe portion 43 and the second pipe portion 44 is positioned above the opening 34 in the vertical direction, and the draft However, in the A direction, it approaches the inflow portion 21 side, but since the communication port 30 faces upward and the length of each slit 32 is as described above, drainage leaks from the communication port 30. There is no.

  Further, when the communication port 30 is inclined so as to face downward, the connection position between the first pipe part 43 and the second pipe part 44 is positioned below the opening 34 in the vertical direction. The draft is located at the opening 34 in the A direction and does not approach the communication port 30, so that the drainage stored in the trap body 20 does not leak from the communication port 30.

  However, the arrangement direction of the main drain pipe 12 may be inclined with respect to the vertical direction. In this case, when the inclination is large, the pin 51 is removed so that the A direction is directed to the vertical direction. Depending on the situation, the attachment / detachment state of the pin 51 is appropriately adjusted. However, in this case as well, the sealing performance and drainage performance are not immediately reduced.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to such specific embodiments, and various modifications and changes can be made within the scope of the gist of the present invention described in the claims. It can be changed.

  For example, as the end of the sealing cylinder 23 on the bottom wall 25 side of the trap body 20 approaches the inner wall of the trap body 20 on the side where the outflow portion 22 is disposed in the B direction, the trap body 20 has a shape in which the distance from the inner surface of the bottom wall 25 is increased, that is, the end is opposed to the inner surface of the bottom wall 25 of the trap body 20 and is the inner wall of the trap body 20 The shape opposite to the inner wall on the side where the outflow portion 22 is disposed in the direction is obtained by adopting a mode in which the end portion of the sealing cylinder 23 is cut obliquely and linearly. However, the aspect in which the end portion of the sealing cylinder 23 is cut obliquely is not limited to a linear shape, and may be appropriately selected such as a curved shape or a stepped shape.

  Moreover, in the said form, although the shape of the rectification | straightening protrusion 33 is a rotary body centering on A direction, the shape of the rectification | straightening protrusion 33 is not this shape, and the top part is the outflow part 22 in C direction. It can be made into an eccentric shape as necessary, such as being far from the center.

  Note that the end of the sealing cylinder 23 on the bottom wall 25 side of the trap body 20 may have a shape that simply faces the bottom 25.

  Further, the rectifying protrusion 33 is not necessarily required, and the upper surface of the bottom wall 25 of the trap body 20 may be a flat surface.

  The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.
