However, the S trap structure shown in Patent Document 2 and Patent Document 3 has a problem that high-pressure cleaning downstream of the trap portion is possible, but the inside of the trap cannot be cleaned.

The present invention was devised in view of the current situation, and the object of the present invention is that the cleaning operator can easily perform the cleaning without working in an unreasonable posture, and further, the inside of the trap. It is also intended to provide a drain trap structure that can be cleaned cleanly.

In order to achieve the above object, in the drain trap structure according to claim 1, a partition body separating the sink side and the drain pipe side of the drain trap portion connected to the bottom portion of the sink is provided at the bottom portion of the sink. In the drain trap structure that is detachable from the sink side at the bottom of the waste storage section having a substantially concave section provided below, the partition body is substantially L-shaped in the vertical piece portion and the bottom piece portion. The drainage trap is connected to the bottom of the sink, and the drainage trap can be inserted into and removed from the drainage trap that communicates with the dust storage. The partition body is configured by the partition body, and the partition body is formed of the same material as the material of the sink or is colored differently .

  As described above, according to the first aspect of the present invention, the partition wall portion separating the sink side and the drain pipe side of the drain trap portion connected to the bottom portion of the sink can be inserted and removed from the sink side. Therefore, it functions as a normal S trap when it is inserted, and when it is removed, it becomes a U-shaped opening with a wide opening, so that the cleaning nozzle can be inserted from the sink side in an easy posture. Since the work can be performed and the inside of the drain trap can be cleaned cleanly, an excellent effect of being hygienic can be obtained.

Further, in this invention, the partition wall body, with a vertical piece and bottom piece portion since it is configured to continuously provided to the grip piece formed by substantially L-shaped, grips the grip piece partition wall The body can be easily inserted and removed, and the gripping piece does not protrude from the inner surface of the sink, so that it does not interfere with the washing operation in the sink, and by designing the gripping piece , Appearance quality can be improved.

Further, according to the present invention, the drain trap includes a dust storage portion that is detachably fitted to the bottom portion of the sink, and the partition body that can be inserted into and removed from the drain trap portion communicating with the dust storage portion. Since the partition body is configured, the partition body does not protrude into the sink, and the effect of not interfering with the washing operation in the sink can be obtained. Furthermore, since the partition wall is formed of the same material as the sink material or is colored differently, the image of the sink can be changed as appropriate, and can be easily distinguished from the conventional sink. Advertising functions can also be added.

  Hereinafter, the present invention will be described in detail based on embodiments of the invention shown in the accompanying drawings.

  1 is a right side view of a sink to which a drain trap according to Embodiment 1 of the present invention is attached, FIG. 2 is a plan view of the sink, and FIG. 3 is a partially cutaway perspective view showing the structure of the drain trap. 4 is a sectional view of the drain trap, FIG. 5 is a half plan view of the drain trap, FIG. 6 is a front sectional view of the drain trap, and FIG. 7 is a sectional view of the partition wall of the drain trap. 8 is a cross-sectional view taken along the line AA of FIG.

  That is, as shown in FIGS. 1 and 2, the drain S trap 10 according to the first embodiment is connected to the drain hole 3 formed in the bottom 2 of the sink 1, and the downstream end is connected to the downstream end. A sewer pipe 4 is connected in communication.

The drainage S trap 10 includes a dust storage portion 12 having a substantially concave concave section having a flange portion 11 fitted and locked to a stepped portion of the drainage hole 3, and a bottom portion 13 of the dust storage portion 12. A drain trap part 15 having a substantially U-shaped cross section that communicates with the upper end thereof, and a partition body 16 that defines the drain trap part 15 in an S shape.

The partition body 16 is formed of a substantially L-shaped gripping portion including a vertical piece portion 18 that is in close contact with the inner peripheral wall surface 17 of the dust storage portion 12 and a bottom piece portion 19 that is in close contact with the bottom portion 13 of the dust storage portion 12. It is comprised from the piece part 20 and the partition part 21 extended from this holding piece part 20 to the drain trap part 15 direction.

A grip piece 22 is projected from the vertical piece 18 and a drain hole 23 is formed in the bottom piece 19. In addition, although four are opened in the present Example 1, the number of drain holes can be increased / decreased suitably. Further, instead of the grip piece 22, an appropriate clue part such as a hole may be formed.
