(First Embodiment)
1 and 2 are perspective cross-sectional views showing a drain trap according to the first embodiment.
As shown in FIGS. 1 and 2, the drain trap 10 includes a water sealing storage unit 12 and a water sealing cylinder 14. The drain trap 10 is used for the unit bath 100, which is one of the facilities around the water. The drain trap 10 is not a drain trap (drainage basin) commonly used for a plurality of water-related equipment, but is used only for one water-related equipment and is a drain trap dedicated to equipment that receives only drainage from one water-related equipment. Is.

The sealed water storage unit 12 is formed in a hollow shape and stores sealed water in the internal space. The sealed water storage unit 12 has a receiving port 20, an inflow port 22, and an outflow port 24. The receiving port 20 is connected to a drain port 106 provided at the bottom of the recess 104 of the washing place 102 of the unit bath 100. The inflow port 22 is connected to the drain port 112 of the bathtub 110 via the pipe 108. The outlet 24 is connected to the drain pipe 114. The outflow port 24 is arranged above the lower end of the sealed water storage unit 12, for example, and is provided facing sideways. As a result, for example, in the sealed water storage unit 12, it is possible to store sealed water in a region below the outlet 24.

The inlet 20 and the drain 106 are covered, for example, by a cover 116. The cover 116 is fitted into the recess 104, for example, and is substantially flush with the washing area 102. The drainage from the washing place 102 flows into the receiving port 20 and the drainage port 106 through a gap between the recess 104 and the cover 116.

The sealed water storage unit 12 causes the water flowing in from the receiving port 20 and the inflow port 22 to flow out from the outflow port 24. In other words, the sealed water storage unit 12 causes the inflowing water to flow out to the drain pipe 114 via the outlet 24.

The water bottle 14 has a substantially cylindrical shape. The water sealing cylinder 14 is attached to the water sealing storage unit 12 in a state of being inserted into the water sealing storage unit 12 from the receiving port 20. In other words, the water bottle 14 is attached to the water storage unit 12 so as to extend downward from the receiving port 20.

On the outer peripheral surface of the water sealing cylinder 14, a plurality of engaging grooves 14a for engaging with each of the plurality of engaging claws 26 provided in the vicinity of the receiving port 20 of the water sealing storage portion 12 are provided. The water sealing cylinder 14 is detachably attached to the water sealing storage portion 12 by engaging each engaging groove 14a with each engaging claw 26. Further, the position of the water bottle 14 in the vertical direction is determined by the engagement between the engaging grooves 14a and the engaging claws 26. Thereby, for example, it is possible to prevent the water bottle 14 from being lifted by the drainage that has flowed into the water seal storage unit 12.

Further, on the outer peripheral surface of the water sealing cylinder 14, for example, a packing made of an elastic body such as rubber is provided, and in a state of being attached to the water sealing storage unit 12, there is a space between the outer peripheral surface and the inner peripheral surface of the water sealing storage unit 12.

FIG. 7 is a perspective cross-sectional view showing the water bottle according to the third embodiment.
As shown in FIG. 7, in this example, the lower portion 62 of the water bottle 60 is formed substantially integrally with the upper portion 61. Then, in the water bottle 60, the hardness of the lower portion 62 is lower than the hardness of the upper portion 61. For example, the material of the lower portion 62 is different from the material of the upper portion 61. The lower portion 62 is made of a softer material than the upper portion 61. For the upper portion 61, for example, a hard resin material such as ABS resin or polypropylene (PP) is used. On the other hand, a soft resin material such as elastomer is used for the lower portion 62.

The lower portion 62 is formed substantially integrally with the upper portion 61 by, for example, two-color molding. The upper portion 61 and the lower portion 62 may be integrally formed by, for example, bonding or welding after being molded as separate parts.

For example, the lower portion 62 may be made of substantially the same material as the upper portion 61, and the hardness of the lower portion 62 may be lower than the hardness of the upper portion 61 by changing the thickness or the like. In this case, the upper portion 61 and the lower portion 62 can be integrally formed by one molding.

In the water bottle 60, the color of the lower portion 62 is darker than the color of the upper portion 61. For example, the color brightness of the lower portion 62 is lower than the color brightness of the upper portion 61. That is, the color of the lower portion 62 is closer to black than the color of the upper portion 61. The color of the upper portion 61 is, for example, ivory or beige. As a result, it is possible to make the color relatively bright and make stains and the like less noticeable. The color of the lower portion 62 is, for example, dark brown or black. Thereby, dirt and the like can be made inconspicuous.

As described above, in the water bottle 60 according to the present embodiment, the hardness of the lower portion 62 is lower than the hardness of the upper portion 61. The upper end of the lower portion 62 is arranged above the maximum water level MHP of the sealed water in the sealed water storage portion 12. This makes it easier to cut the lower portion 62 with cutting means such as scissors. Then, when a double trap is accidentally formed, the trap function of the drain trap 10 can be easily lost by cutting the portion above the maximum water level MHP in the lower portion 62 by the cutting means. .. As a result, the double trap can be easily eliminated without performing a large-scale construction work. It is possible to suppress the deterioration of drainage and the generation of air suction noise due to the double trap.

Further, in the water bottle 60, the color of the lower portion 62 is darker than the color of the upper portion 61. As a result, it is possible to make it easy to understand the portion to be cut by the difference in color. It is possible to prevent the lower portion 62 from being accidentally cut at a position below the maximum water level MHP of the sealed water, and to improve the workability of cutting.

Further, by darkening the color of the lower portion 62, when the drain trap 10 is used in a state where the lower portion 62 is not cut, mold and dirt adhering to the lower portion 62 can be made less noticeable. For example, when a soft material such as an elastomer is used for the lower portion 62, black mold or the like may easily occur on the lower portion 62. At this time, by preliminarily setting the lower portion 62 to a color close to black, the visibility of black mold can be suppressed.

FIG. 8 is a perspective sectional view showing a modified example of the water bottle according to the third embodiment.

The soft portion 72a is arranged on the lower side of the upper portion 71. The hard portion 72b is arranged on the lower side of the soft portion 72a. The soft portion 72a is formed substantially integrally with the upper portion 71 and the hard portion 72b. The upper end of the soft portion 72a is arranged above the maximum water level MHP of the sealed water of the sealed water storage portion 12 in a state of being attached to the sealed water storage portion 12.

The hardness of the soft portion 72a is lower than the hardness of the upper portion 71. The hardness of the hard portion 72b is higher than the hardness of the soft portion 72a. The hardness of the hard portion 72b is substantially the same as the hardness of the upper portion 71, for example. That is, the soft portion 72a is softer than the upper portion 71 and the hard portion 72b. For the soft portion 72a, for example, an elastomer or the like is used. For the hard portion 72b, for example, ABS resin, polypropylene (PP), or the like is used.

Also in this water bottle 70, the trap function of the drain trap 10 can be easily lost by cutting the portion of the soft portion 72b above the maximum water level MHP. As described above, the portion having a hardness lower than that of the upper portion 71 may be at least a part of the lower portion 72. The hardness of at least a part of the lower portion 72 is made lower than the hardness of the upper portion 71. Then, at least a part of the upper end thereof is arranged above the maximum water level MHP in a state of being attached to the sealed water storage unit 12. As a result, as described above, in the water bottle 70, the trap function of the drain trap 10 can be easily lost.

Further, in the water bottle 70, the color of the soft portion 72a is made darker than the color of the upper portion 71. As a result, the portion to be cut can be easily understood by the difference in color. It is possible to prevent the soft portion 72a from being accidentally cut at a position below the maximum water level MHP of the sealed water, and to improve the workability of cutting. The color of the hard portion 72b may be the same as the color of the soft portion 72a, or may be the same as the color of the upper portion 71.

Further, when the soft portion 72a and the hard portion 72b are provided on the lower portion 72, all of the soft portion 72a seals the sealing water storage portion 12 in a state where the water sealing cylinder 70 is attached to the sealing water storage portion 12. It may be placed above the maximum water level MHP. As a result, the trap function of the drain trap 10 can be reliably lost no matter where the soft portion 72a is cut, and the workability of cutting can be further improved.

As a result, in the drain trap 80, the position of the upper end 85a of the drain pipe 85 becomes the maximum water level MHP of the sealed water of the sealed water storage unit 81.

The perforated plate 83 is mounted on the sealed water storage portion 81 and covers the opening 81a above the sealed water storage portion 81. The pipe 84 is attached to, for example, the perforated plate 83. One end of the pipe 84 is arranged in the sealed water storage portion 81 via the perforated plate 83. The other end of the pipe 84 is arranged outside the water sealing storage portion 81, and is connected to, for example, a drain hose of a washing machine. As a result, the drainage from the washing machine flows into the sealed water storage unit 81 via the drain hose and the pipe 84.

The water bottle 82 is attached to the upper part of the water seal storage unit 81, and is provided in the water seal storage unit 81, for example. The water sealing cylinder 82 extends in the vertical direction and surrounds one end of the pipe 84 and the drainage pipe 85 that have entered the water sealing storage portion 81. Further, a gap is provided between the lower end of the water sealing cylinder 82 and the water sealing storage portion 81. The perforated plate 83 is provided outside the water sealing cylinder 82, and has an opening 83a that communicates the internal space and the external space of the water sealing storage portion 81.

The water bottle 82 has an upper portion 91 arranged above the maximum water level MHP and a lower portion 92 having at least a part thereof arranged below the maximum water level MHP. The lower portion 92 is removable from the upper portion 91. The configuration of attaching the lower portion 92 to the upper portion 91 may be any configuration such as screwing or engagement as described with respect to the first and second embodiments. Alternatively, as described with respect to the third embodiment, the hardness of the lower portion 92 may be made lower than the hardness of the upper portion 91 so that the lower portion 92 can be easily cut.

The water bottle 82 has a partition 93 that partitions the pipe 84 and the drain pipe 85, and a communication port 94 that is provided directly above the partition 93 and communicates the space inside the water bottle 82 with the outside space. Have more. A plurality of communication ports 94 are provided, for example, around the axis of the water bottle 82. In this example, the partition portion 93 and the communication port 94 are provided in the lower portion 92. On the contrary, the partition portion 93 and the communication port 94 may be provided in the upper portion 91.

In the drain trap 80, the water that has flowed in through the pipe 84 passes through the water bottle 82 and flows into the drain pipe 85 through the communication port 94, the lower end of the water bottle 82, and the gap between the water storage unit 81. To do. Further, in the drain trap 80, when the water level of the sealing water in the sealing water storage unit 12 is at least at the maximum water level MHP, the lower end of the sealing cylinder 82 is submerged in the sealing water. As a result, the sealing water storage unit 81 and the sealing cylinder 82 block the path from the pipe 84 to the drainage pipe 85 by sealing water. Therefore, it is possible to prevent odors and pests from the drain pipe 85 from moving toward the washing machine pan side.

Then, as shown in FIG. 9B, when the lower portion 92 is removed, the lower end of the upper portion 91 is located above the maximum water level MHP of the sealed water in the sealed water storage portion 81. .. Therefore, also in this drain trap 80, the trap function of the drain trap 80 can be easily lost by removing or cutting the lower portion 92. As a result, even in the drain trap 80, the double trap can be easily eliminated without performing a large-scale construction or the like. It is possible to suppress the deterioration of drainage due to the double trap.

The first embodiment shows an example in which the present invention is applied to a drain trap 10 that allows water that has flowed into the inside to flow out in the lateral direction. Not limited to this, as shown in the present embodiment, the present invention may be applied to the drain trap 80 that allows the water that has flowed into the inside to flow out in the vertical direction. The configuration of the drain trap is not limited to the above, and may be any configuration having at least a sealing water storage unit and a sealing cylinder.

In each of the above embodiments, the unit bath and the washing machine pan are shown as water-related equipment. The water-related equipment is not limited to these, and may be any water-related equipment that uses a drain trap, such as a system kitchen, a vanity, or a urinal.
