  The drainage outlet 72 allows the washing ground drainage and bathtub drainage flowing into the outflow chamber 7 from the communication port 63 to flow out of the drain trap 5. As shown in FIG. 3, the drainage outlet 72 opens in the horizontal direction toward the outside of the drainage trap 5 above the communication port 63. The washing ground drainage and the bathtub drainage flowing into the outflow chamber 7 from the communication port 63 flows into the upper space 75 of the outflow chamber 7 when the sealing surface F is exceeded, and the drain trap 5 It is leaked outside.

  Next, for the drain trap 5 according to the present invention, when the partition plate 65 is attached between the receiving chamber 6 and the outflow chamber 7 and when the partition plate 65 is removed from between the receiving chamber 6 and the outflow chamber 7 The operation of the above will be described.

  First, the case where the partition plate 65 is attached between the receiving chamber 6 and the outflow chamber 7 will be described. In this case, the drain trap 5 has a function of storing sealed water to block the drain flow path and a function of generating a vortex.

First, in the drain trap 5, the function of accumulating sealed water and closing the drain channel will be described.
As shown in FIGS. 1 and 3, the washing ground drainage discharged from the washing ground pan 3 (see FIG. 1) passes through the hair catcher 11 (see FIG. 1) and flows into the receiving chamber 6. The bathtub drainage from the bathtub 2 is introduced into the drainage trap 5 through the bathtub drainage port 21 and the bathtub drainage discharge pipe 12. The bathtub drainage introduced into the drainage trap 5 (see FIG. 3) flows into the receiving chamber 6 through the bathtub drainage inlet 811, the introduction path 81, the rising pipe 83, and the bathtub drainage inlet 62.

  Washroom wastewater and bathtub wastewater that has flowed into the receiving chamber 6 flow out to the external outlet discharge pipe 13 through the communication port 63, the outflow chamber 7, and the drainage outlet 72. When the outflow of washing ground drainage or bathtub drainage stops, sealed water accumulates in the receiving chamber 6 and the outflow chamber 7 up to the sealing surface F (see FIG. 3). Since the communication port 63 is located inside the sealed water collected on the sealed surface F, the drainage channel is blocked by the sealed water. This prevents the odor from the external discharge pipe 13 from flowing back into the bathroom 1. In addition, pests and the like are prevented from entering the bathroom 1.

Next, the function of generating a vortex in the drain trap 5 will be described.
As shown in FIG.1 and FIG.3, when the drain plug 22 (refer FIG. 1) of the bathtub 2 (refer FIG. 1) is opened, the bathtub waste_water | drain discharged | emitted from the bathtub 2 will be the bathtub drain discharge pipe 12 (refer FIG. 1). ) And flows into the inside of the drain trap 5 from the bathtub drain inlet 811. Then, the bathtub drainage flows through the rising pipe 83 and flows into the upper portion of the receiving chamber 6 through the bathtub drainage inlet 62. The bathtub drainage that flows into the upper part of the receiving chamber 6 swirls along the inner peripheral surface above the receiving chamber 6 to form a vortex, and the generated vortex flows as an upward vortex and rises.

  This ascending vortex rises to the vicinity of the drain outlet cover 32 mounted on the upper surface of the drain 31 (see FIG. 1). Due to the rising vortex, dust and hair adhering to the inner peripheral surface of the drainage basin 31 and the hair catcher 11 are dropped well. Garbage and hair are collected at the center of the vortex and fall downward from the center of the vortex. And dust and hair are collected at the center of the bottom surface of the hair catcher 11. Thereby, the hair catcher 11 is maintained in a state in which no hair is attached to other than the central portion, and the slime and the like attached to the inner and outer surfaces of the hair catcher 11 can be removed. As a result, the hair catcher 11 has good water flow. Moreover, the slime etc. adhering to the inner peripheral surface of the receiving chamber 6 can also be removed.

  Here, as shown in FIG. 3, the rising pipe 83 is formed in a tubular shape and extends upward along the partition plate 65. Therefore, the bathtub drainage can be introduced above the inside of the receiving chamber 6 through the inside of the tubular portion of the rising pipe 83. As a result, a strong vortex is formed in the upper part of the receiving chamber 6, that is, in the vicinity of the hair catcher 11. Therefore, the dust inside the hair catcher 11 is efficiently collected near the center, and the hair catcher 11 is washed by a strong vortex.

  Moreover, as shown in FIG. 3, the inner surface of the receiving chamber 6 is substantially spherical. Therefore, by introducing the bathtub drainage along the substantially spherical inner surface of the receiving chamber 6, a vortex can be generated vigorously.

  As shown in FIG. 3, the bathtub drainage inlet 62 opens so as to discharge the bathtub drainage toward the tangential direction of the substantially spherical inner surface of the receiving chamber 6. Therefore, by introducing the bathtub drainage in the tangential direction of the substantially spherical inner surface of the receiving chamber 6, the bathtub drainage is maintained from the bathtub drainage inlet 62 through the rising pipe 83 while maintaining the momentum of the water. Can flow inside. Thereby, since a vortex | eddy_current generate | occur | produces along the inner surface of the receiving chamber 6, a vortex | eddy_current can be generated vigorously.

  In addition, as shown in FIG. 3, the bathtub drainage branched from the introduction pipe 81 to the bypass pipe 82 flows out from the drainage outlet 72 to the external outlet discharge pipe 13. For this reason, by adjusting the flow rate of the bathtub drainage branched to the riser 83, it is possible to prevent the washroom drainage and the bathtub drainage from overflowing from the receiving chamber 6. Moreover, the bathtub drainage of the bathtub 2 can be discharged | emitted in a short time.

Next, the operation when the partition plate 65 and the rising pipe 83 are removed will be described.
Conventionally, when performing reform such as newly installing a bathroom, a new drain trap may be provided in the drain channel. Here, in the drainage channel provided with a new drain trap, if the drain trap is already provided, the resistance of the drain flow increases and causes drainage failure. In this way, a structure in which two or more drain traps exist in series in the drain channel (pipe) is called a double trap structure or a double trap structure.

  In the case of a double trap structure (double trap structure), it becomes necessary to eliminate the double trap structure. In this case, in the present invention, the partition plate 65 can be removed from between the receiving chamber 6 and the outflow chamber 7 from the state shown in FIGS. 3 and 5 to the state shown in FIGS. 6 and 7. Specifically, in the present embodiment, the partition plate 65 and the rising pipe 83 can be integrally removed from the receiving chamber 6.

  As shown in FIGS. 6 and 7, when the partition plate 65 is removed from between the receiving chamber 67 and the outflow chamber 7, the section between the receiving chamber 6 and the outflow chamber 7 is opened, and a trap release opening 68 is formed. . The upper end 651 of the partition plate 65 is positioned higher than the lower end 721 of the drainage outlet 72 when the partition plate 65 is attached between the receiving chamber 67 and the outflow chamber 7. Therefore, the upper end 681 of the trap release opening 68 is positioned higher than the lower end 721 of the drainage outlet 72.

  Therefore, even if the sealed water is accumulated up to the sealing surface F, a communication space that connects the receiving chamber 67 and the outflow chamber 7 is formed above the height of the sealing surface F (see FIGS. 3 and 6). Therefore, in the drain trap 5, a sufficiently large communication space through which air passes is secured above the sealed water, and the drain channel is not blocked by the sealed water. Therefore, the double trap structure can be eliminated by removing the partition plate 65.

  Further, as shown in FIGS. 6 and 7, the partition plate 65 and the rising pipe 83 can be integrally removed from between the receiving chamber 6 and the outflow chamber 7, so that the vicinity of the bypass pipe 82 and the communication port 63 is obtained. Maintenance work such as cleaning and inspection can be performed easily. Further, maintenance work such as cleaning and inspection of the partition plate 65 and the rising pipe 83 can be easily performed.

  Specifically, the hair catcher 11 (see FIG. 1) attached to the upper part of the receiving chamber 67 is removed, and a finger is inserted from the communication port 63 toward the outflow chamber 7 from the state shown in FIGS. By grasping and rotating the plate 65, the partition plate 65 and the rising pipe 83 can be integrally removed from the receiving chamber 6 in the state shown in FIGS. When the removed partition plate 65 and the rising pipe 83 are mounted, the partition plate 65 is grasped with a finger at a portion corresponding to the communication port 63, and the partition plate 65 is engaged with the wall member of the receiving chamber 6. Can be attached to the connecting portion opening 812 (see FIGS. 6 and 7) of the bathtub drainage circulation pipe 8.

According to the drain trap 5 of the present embodiment described above, the following effects are obtained.
The drain trap 5 of the present embodiment includes a wash basin drain inlet 61 for allowing the wash basin drain introduced from above, a bathtub drain inlet 62 for allowing the bathtub drain introduced from the side, the wash basin drain and The receiving chamber 6 having a communication port 63 through which the bath drainage flows out, the communication port 63 through which the washing ground drainage and the bath drainage flowing out from the communication port 63 flow in, and a horizontal opening above the communication port 63 to communicate with each other The outflow chamber 7 having the drainage outlet 72 for discharging the washing ground drainage and the bathtub drainage flowing in from the mouth 63, the introduction path 81 into which the bathtub drainage is introduced, the upstream side is connected to the introduction pipe 81, and the downstream side is A bath having a bypass pipe 82 located on the drainage outlet 72 side, and a rising pipe 83 having an upstream side connected to the introduction pipe 81 and a downstream side connected to the bathtub drainage inlet 62. A drainage pipe 8, and a partition plate 65 that is detachably disposed between the receiving chamber 6 and the outflow chamber 7, and that partitions the receiving chamber 6 and the outflow chamber 7, of the upper end portion 651 of the partition plate 65 The height is higher than the position of the lower end 721 of the drainage outlet 72.

  Therefore, the drainage outlet 72 is opened in the horizontal direction above the communication port 63, so that the sealed water is accumulated up to the sealing surface F inside the receiving chamber 6 and the outflow chamber 7. Since the communication port 63 is located inside the sealed water collected up to the sealed surface F, the drainage flow path is blocked by the sealed water. This prevents the odor from the external discharge pipe 13 from flowing back into the bathroom 1. In addition, pests and the like are prevented from entering the bathroom 1.

  In addition, the bathtub drainage flows into the receiving chamber 6 through the ascending pipe 83 and the bathtub drainage inlet 62. The bathtub drainage that has flowed into the receiving chamber 6 swirls along the inner peripheral surface of the receiving chamber 6 to form a vortex, and the generated vortex flows as an upward vortex and rises. Thereby, the hair catcher 11 is maintained in a state in which no hair is attached to other than the central portion, and the slime and the like attached to the inner and outer surfaces of the hair catcher 11 can be removed. Thereby, as for the hair catcher 11, water flow becomes favorable.

  The partition plate 65 is detachably disposed between the receiving chamber 6 and the outflow chamber 7. Therefore, the double trap structure can be easily eliminated simply by removing the partition plate 65 from between the receiving chamber 6 and the outflow chamber 7.

  As described above, the present invention can be provided with a function of accumulating sealed water to block the drainage flow path and a function of generating a vortex flow, and a structure that can easily eliminate the double trap structure.

  Further, in the present embodiment, the bypass pipe 82 extends so as to guide the bathtub drainage flowing through the introduction pipe 81 to the drainage outlet 72 by bypassing the receiving chamber 6. Therefore, the bypass pipe 82 can adjust the flow rate of the bathtub drainage branched to the ascending pipe 83 to suppress overflow of the washroom drainage and the bathtub drainage from the receiving chamber 6. Moreover, the bypass pipe 82 can discharge the bathtub drainage of the bathtub 2 in a short time.

  The ascending pipe 83 extends so as to guide the bathtub drainage flowing through the introduction pipe 81 to the bathtub drainage inlet 62 so as to generate a vortex above the interior of the receiving chamber 6. Therefore, a vortex is generated above the interior of the receiving chamber 6 by the rising pipe 83, and a strong vortex is formed in the upper portion of the receiving chamber 6, that is, in the vicinity of the hair catcher 11. Thereby, the dust inside the hair catcher 11 is efficiently collected near the center, and the hair catcher 11 is washed by a strong vortex.

  In the present embodiment, the rising pipe 83 is formed in a tubular shape and extends upward along the partition plate 65. Therefore, the bathtub drainage can be introduced above the interior of the receiving chamber 6 through the tubular interior of the rising pipe 83. As a result, a strong vortex is formed in the upper part of the receiving chamber 6, that is, in the vicinity of the hair catcher 11. Thereby, the dust inside the hair catcher 11 is efficiently collected near the center, and the hair catcher 11 is washed by a strong vortex.

  In the present embodiment, the ascending pipe 83 is formed integrally with the partition plate 65. Therefore, since the ascending pipe 83 and the partition plate 65 can be integrally removed from between the receiving chamber 6 and the outflow chamber 7, maintenance work such as cleaning and inspection of the vicinity of the bypass pipe 82 and the communication port 63, etc. Can be easily performed. Further, maintenance work such as cleaning and inspection of the partition plate 65 and the rising pipe 83 can be easily performed.

  Moreover, in this embodiment, the inner surface of the receiving chamber 6 is substantially spherical. Therefore, by introducing the bathtub drainage along the substantially spherical inner surface of the receiving chamber 6, a vortex can be generated vigorously.

  In the present embodiment, the bathtub drainage inlet 62 opens so as to discharge the bathtub drainage toward the tangential direction of the inner surface of the receiving chamber 6. Therefore, by introducing the bathtub drainage in the tangential direction of the substantially spherical inner surface of the receiving chamber 6, a vortex flow is generated along the inner surface of the receiving chamber 6, so that the vortex can be generated vigorously.

  Moreover, in this embodiment, it is the bathroom 1 provided with the drain trap 5, the bathtub 2, and the washing-place pan 3. Therefore, when the bathroom 1 is newly installed, the double trap structure can be eliminated. Further, by providing the bathroom 1 with the drain trap 5, the frequency of removing dust and hair adhering to the hair catcher 11 is reduced, and the labor for cleaning the bathroom 1 is reduced.

As mentioned above, although preferable one Embodiment of the drain trap of this invention was described, this invention is not restrict | limited to embodiment mentioned above, It can change suitably.
For example, in the said embodiment, although the inner surface of the receiving chamber 6 was formed in the substantially spherical shape, it is not restricted to this. For example, the inner surface of the receiving chamber 6 may be formed in a substantially cylindrical shape.

  Moreover, in the said embodiment, although the receiving side outflow port of the receiving chamber 6 and the outflow side inflow port of the outflow chamber 7 were made into the common communicating port 63, it is not restricted to this. For example, a connecting pipe is arranged between the outflow side inlet of the outflow chamber 7, one end of the connecting pipe is used as the receiving side outflow of the receiving chamber 6, and the other end of the connecting pipe is used as the outflow side flow of the outflow chamber 7. It may be an entrance.
