Description

  The present invention relates to a drain trap apparatus, and more particularly to a drain trap apparatus that accepts inflow of drainage from at least two drain outlets and discharges it downstream.

  In many cases, at the drain of a bathroom washroom, hair adheres to the eye plate and water cannot pass sufficiently. Therefore, for example, as in Patent Document 1, the inside of the main body is divided into two chambers, an inflow chamber and an outflow chamber, and an opening for inflow of wash basin drainage is provided on the top surface of the inflow chamber, and bathtub drainage flows into the side surface of the inflow chamber. There is disclosed a drain trap provided with a tub drainage inlet and vortex generating means for generating a vortex in the inflow chamber by the tub drain. According to this, since the eddy current is generated along the inner peripheral surface of the inflow chamber, the hair adhering to the eye plate can be peeled off satisfactorily and the water flow is improved.

  Moreover, in the drain trap which accepts the inflow of drainage from the bathroom outlet and the bathtub outlet and merges these drains and discharges them from one outlet, the drainage channels connected from both outlets are integrated. Then, there was a risk that the drainage would flow backward from the drain on the washing station side to the drain on the bathtub side. On the other hand, if the drainage channel connected from both drainage ports is completely shielded, when a large amount of drainage flows down from the drainage port on the bathtub side, siphon phenomenon occurs due to drainage from the bathtub near the drainage port, and There was a possibility that the wastewater stored in the trap was pulled and the trap on the washing station side would run out of water.

  Therefore, as disclosed in Patent Document 2, a drain trap provided with a water passage that branches off from a drain channel on the bathtub side and opens above the sealed portion of the drain channel on the washing station side is disclosed. According to this configuration, if there is a small amount of drainage from the bathtub-side drain outlet, it is discharged from the outlet, but if there is a large amount of drainage from the bathtub-side drain outlet, Since the portion passes through the water passage and is discharged above the sealing portion of the drainage channel on the washing station side, the sealing portion of the drainage channel on the washing station side does not run out of water.

Patent No. 3886055 JP 2007-197943 A

  However, since the drainage trap of Patent Document 1 generates eddy currents by allowing all of the bathtub drainage to flow into the inflow chamber, the configuration as in Patent Document 2 cannot be adopted, There is a possibility that drainage flows backward from the drainage port to the drainage port on the bathtub side, and there is a possibility that drainage from the drainage port on the bathtub side overflows from the drainage port on the washing place side.

  Then, an object of this invention is to provide the waste_water | drain trap apparatus which can peel off the hair etc. which adhere to the eye plate of a waste_water | drain opening well, preventing the backflow and tearing of waste_water | drain.

  In order to achieve the above object, a drain trap apparatus according to claim 1 includes a first drain port that receives an inflow of drainage, and a first drain channel that flows down the drainage flowing from the first drain port.

  Moreover, the drain trap apparatus according to claim 2 is the drain trap apparatus according to claim 1, wherein the bottom plate of the second drain port has a bottom part lower than the spiral discharge hole. It is characterized by being formed.

  The drain trap apparatus according to claim 3, wherein the drain trap apparatus according to claim 1 or 2 is capable of attracting a part of drainage flowing through the first drainage channel to a lower end of the upright pipe. And the movable piece closes a part of the first drainage channel when the flow rate of the first drainage channel is less than a predetermined value, and induces drainage to the lower end of the upright pipe, When the flow rate of the first drainage channel is greater than or equal to a predetermined value, the first drainage channel is opened.

  According to the drain trap apparatus of claim 1, the lower end of the upright pipe communicates with the first drainage flow path that continues from the first drainage outlet, and the upper end of the upright pipe is below the second drainage outlet. The upper end peripheral surface of the upright pipe is provided with a spiral discharge hole for supplying drainage to the lower side of the second drainage port in a spiral shape, so that the eyelet of the second drainage port has a spiral shape. The waste water supplied from the discharge hole flows in a spiral shape, and the hair attached to the eye plate is peeled off, so that a good water flow state can be maintained. In addition, since a part of the drainage of the first drainage channel is supplied to the second drainage port side in this way, the trapping of the trap on the second drainage port side can be prevented.

  According to the drain trap apparatus of the second aspect, since the bottom plate of the second drain port is formed so that the bottom part is below the spiral discharge hole, the drainage discharged from the spiral discharge hole is vigorous.

  Hereinafter, the best embodiment of the drain trap apparatus 1 of the present invention will be described with reference to the drawings. As shown in FIG. 1, the drain trap apparatus 1 receives, for example, the drainage of the bathtub 2 and the drainage of the washing place 3 in the bathroom, and discharges the received drainage to the drainage pipe 4 on the downstream side. The drain trap apparatus 1 forms, for example, a first drain port 5 that receives an inflow of drainage from the bathtub 2 and a trap that stores the drainage that flows in from the first drain port 5, and causes the inflowing drainage to flow down. It has a first drainage channel 6 and an eye plate 7 for filtering out foreign substances such as hair. For example, a second drainage port 8 that receives an inflow of drainage from a bathroom washroom 3 and an inflow from the second drainage port 8 And forming a trap for storing the drained wastewater, and the second drainage flow path 9 for flowing down the inflowed wastewater, and the drainage flowing down the first drainage flow path 6 and the second drainage flow path 9 are merged downstream. The discharge port 10 and the lower portion 11 a communicate with the first drainage flow path 6, and the upper portion 11 b flows through the upright pipe 11 disposed below the second drainage port 8 and the second drainage flow path 9. Possible to attract a part of the drainage to the lower end of the upright pipe 11 And a strip 12.

  The first drainage port 5 communicates with an opening provided on the bottom surface 2 a of the bathtub 2 through a straight pipe 13 and receives water stored in the bathtub 2. The upstream end 6a of the first drainage channel 6 communicates with the first drainage channel 5 under the first drainage port 5. The first drainage channel 6 is provided in the washing place 3 in a substantially horizontal direction. It extends to the lower side of the second drainage port 8, and is then formed in an upward slope toward the discharge port 10, so that almost the entire area of the first drainage channel 6 becomes a trap for storing the drainage of the bathtub 2. Has been. In addition, a second drainage channel 9 is formed immediately above the first drainage channel 6 at a position below the second drainage port 8 and shields the first drainage channel 6 and the second drainage channel 9. It is divided by the wall 14.

  The second drainage port 8 is provided at a downstream position of the groove 3a through which the drainage formed on the floor surface of the washing place 3 flows, and the eye plate 7 is screwed by a screw groove provided on the peripheral surface thereof. . A cylindrical deodorizing cylinder 15 formed in a flange shape is fixed to the lower side of the eye plate 7 so that its upper end is in close contact with the inner peripheral surface of the second drain port 8. The second drainage channel 9 is provided along the first drainage channel 6 with the shielding wall 14 as a bottom surface, and is formed in an upward slope toward the discharge port 10, and the deodorizing cylinder 15 and the second drainage are formed. A trap for storing the wastewater flowing in from the second drainage port 8 is formed by the upward slope of the flow path 9.

  The upright pipe 11 has a lower portion 11 a inserted into an opening provided in the shielding wall 14 and is disposed on the first drainage flow path 6 side, and an upper portion 11 b is erected inside the deodorizing cylinder 15. As shown in FIGS. 1 and 2, the lower portion 11a of the upright pipe 11 has a semi-cylindrical shape in which a wall 11c is formed only on the downstream peripheral surface, and the lower surface and the upstream peripheral surface are open. . Further, a flange 11 d fixed to the opening is formed thereon, and an upper portion 11 b of the cylindrical upright pipe 11 is erected inside the deodorizing cylinder 15. The upper portion 11b of the upright tube 11 is closed at the upper surface, and a plurality of spiral discharge holes 11e, which are small-diameter openings, are provided on the peripheral surface near the upper end. As shown in FIG. 3, the spiral discharge hole 11 e is angled in a certain direction with respect to the peripheral surface, and the drainage discharged from the spiral discharge hole 11 e forms a vortex inside the deodorizing cylinder 15.

  The shape of the upright tube 11 is not limited to a cylindrical shape, and may be, for example, a quadrangular cylindrical shape or other polygonal column shapes. Further, a semi-cylindrical wall is formed on the downstream side of the lower portion 11a of the upright pipe 11, but it is not always necessary to form such a wall, and the water flow performance of the first drainage channel 6 is further improved. If necessary, the shape can be made without a wall. In addition, the spiral discharge hole 11e is not limited to the above-described form. For example, a small piece (not shown) is attached to the outlet of the hole to change the direction of discharged water so that the water flow spirals. There may be.

  As shown in FIG. 4, the movable piece 12 is provided on the side of the lower portion 11 a of the upright pipe 11 in the first drainage channel 6, and is horizontal and perpendicular to the flowing direction of the first drainage channel 6. The shaft 12b is provided, and the movable piece main body 12a whose upper end portion is rotatably suspended on the shaft 12b. The movable piece main body 12a is configured in a flat plate shape that can shield a part of the first drainage flow path 6, and when the flow rate of the first drainage flow path 6 is small, the movable piece body 12a hangs down due to its own weight. A part of the drainage is blocked and the drainage is attracted to the lower part 11a of the upright pipe 11. Further, when the flow rate of the first drainage channel 6 is large, as shown in FIG. 5, the first drainage channel 6 is opened by the flow pressure of the drainage. In order to adjust the amount of drainage, the movable piece 12 may be provided with a weight so as to increase the weight of the movable piece 12 as necessary.

  The configuration of the movable piece 12 is not limited to this. For example, the movable piece 12 is configured in a flat plate shape having a hinge and an elastic body such as a spring, and when the flow rate of the first drainage flow path 6 is small, the first drainage flow. A part of the channel 6 may be kept closed, and the first drainage channel 6 may be opened by the flow pressure when the flow rate of the first drainage channel 6 is large. Further, the movable piece 12 is not limited to the shaft 12b provided horizontally, and the shaft 12b may be provided vertically. The shape of the movable piece main body 12a is not limited to a flat plate shape, and may be a curved shape so that the drainage flowing through the first drainage channel 6 can be smoothly collected in the lower portion 11a of the upright pipe 11. .

  In the drain trap apparatus 1 configured as described above, drainage from the washing place 3 flows in from the second drainage port 8, and after hair or the like is filtered by the eye plate 7, the second drainage flow path 9 is passed through as it is. It flows down and is discharged from the discharge port 10 to the downstream drainage pipe 4. On the other hand, when draining the water stored in the bathtub 2, drainage flows from the first drainage port 5 and flows into the first drainage flow path 6. And the drainage which flows through the 1st drainage channel 6 partly hits the lower part 11a of the upright pipe 11, and while raising the inside of the upright pipe 11, the other part of drainage passes through the 1st drainage channel 6. It passes through and is discharged from the discharge port 10 to the downstream drainage pipe 4. The drainage that has risen inside the upright pipe 11 is discharged to the inside of the deodorizing cylinder 15 from the spiral discharge hole 11e. The discharged waste water hits the eye plate 7 while rotating inside the deodorizing cylinder 15 in a spiral manner, and peels off the hair and the like attached to the eye plate 7 and is then stored in the trap of the second drainage channel 9. Then, the water is discharged from the discharge port 10 through the second drainage flow path 9.

  Therefore, since the hair etc. which adhered to the eye plate 7 can be peeled only by draining the water stored in the bathtub 2, a favorable water flow state can be maintained. In addition, since a part of the drainage of the first drainage channel 6 is supplied to the second drainage channel 9, when drainage flows vigorously in the first drainage channel 6, the drainage near the outlet 10. Even if the siphon phenomenon occurs and the drainage stored in the trap of the second drainage channel 9 is pulled, the drainage is newly supplied to the second drainage channel 9, so that the trap is closed. Will not cause.

  Moreover, when the flow of the drainage of the first drainage channel 6 becomes weak, the movable piece 12 blocks a part of the first drainage channel 6 and attracts the drainage to the lower part 11a of the upright pipe 11, so that the spiral discharge The drainage is discharged from the hole 11e vigorously, and a strong vortex can be generated.

  Needless to say, the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.

  For example, in the present embodiment, the bottom of the eye plate 7 is disposed above the spiral discharge hole 11e. However, the present invention is not limited to this. For example, as shown in FIG. It may be configured deeply and the center 7b may be raised. With this configuration, since the bottom surface 7a of the eye plate 7 is lower than the spiral discharge hole 11e, the height of the generated vortex can be measured even when the drainage discharged from the spiral discharge hole 11e is weak. It can be made higher than the bottom surface 7a of the dish 7, and the hair etc. adhering to the eye dish 7 can be peeled off reliably. In addition, the length of the upright tube 11 may be longer than that of the deep plate 7. When configured in this way, the position of the spiral discharge hole 11e can be made higher and higher than the bottom surface 7a of the eye plate 7, so that it is discharged from the spiral discharge hole 11e in the same manner as the above-described structure. Even when the momentum of the discharged water is weak, the height of the generated vortex can be made higher than the bottom surface 7a of the eye plate 7, and the hair attached to the eye plate 7 can be peeled off reliably.

  In addition, in this embodiment, although the drain trap apparatus 1 which receives the waste_water | drain of the bathtub 2 of a bathroom, and the drainage of the washing place 3 was demonstrated, also in the other drain trap apparatus 1 which receives waste_water | drain from two or more drain outlets, this invention. Can be applied.

  The drain trap apparatus 1 of the present invention can be suitably used, for example, in the drain trap apparatus 1 that causes the drainage of the bathtub 2 and the drainage of the washing place 3 in the bathroom to flow down to the drain pipe 4.
