Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drainage device for a sink.

[0002]

[Prior art]

 Conventionally, as shown in FIGS. 4 (a) and 4 (b), an outer box body 2 having an upper surface opened and a receiving portion 1 projecting from an inner peripheral surface of an upper end portion, and a flange extending to an outer peripheral edge of the upper end portion. 3 is mounted on and supported by the receiving portion 1 to connect to the net basket 4 which is detachably mounted in the outer box body 2 and the tube hole 6 formed in the bottom surface 5 of the outer box body 2. There is known a drainage device of a sink provided with the bowl trap 9 and the chrysanthemum cracking rubber 10 which is detachably mounted on the flange 3 of the net basket 4.

In this drainage device of the sink, which is provided at the drainage port 12 of the sink 11, the net basket 4 in the outer box body 2 is used for solid waste such as raw garbage generated during cooking or washing dishes. The object can be collected, and the odor rising from the drain pipe 13 can be blocked by the bowl trap 9 provided at the bottom of the outer box body 2.

[0004]

[Problems to be solved by the device]

 However, in the above conventional technique, as shown in FIG. 4 (a), the bowl trap 9 projects into the outer box body 2, and the shallow net basket 4 must be used. 4 is filled with garbage immediately and must be taken out frequently, discarded and cleaned. Further, as shown in FIG. 4 (b), if the net basket 4 is deepened to increase the ability to collect garbage, the outer casing 2 becomes very deep. In this case, the sink 11 The storage portion 14 of is narrowed.

In addition, since the sealing water 15 for blocking the odor rising from the drain pipe 13 is always stored in the bottom of the outer box body 2, bacteria and mold are apt to be generated, and slime and dirt are not easily generated. It is the cause.

Therefore, the present invention has been devised to solve the above-mentioned problems in the conventional technology. That is, the problem is that the ability to collect the net basket 4 can be increased and the outer box It is an object of the present invention to provide a drainage device for a sink that can keep bacteria and mold in the body 2 clean and keep it clean.

[0007]

[Means for Solving the Problems]

 In the drainage device of the sink of the present invention, an outer box body 2 having an upper surface opened and a receiving portion 1 projecting from an inner peripheral surface of an upper end portion, and a flange 3 extending to an outer peripheral edge of the upper end are provided in the receiving portion 1. The upper end opening is connected to the mesh basket 4 that is mounted in and out of the outer box body 2 by being mounted and supported, and the pipe hole 6 formed in the bottom surface 5 of the outer box body 2. The character trap 7 is provided.

Further, a strainer 8 detachably provided in the tube hole 6 may be provided.

[0009]

[Action]

 In the drainage device of the sink of the present invention, the S-shaped trap 7 is connected to the pipe hole 6 without protruding into the outer box body 2, and the sealing water 15 is stored in the S-shaped trap 7. It is a thing.

Further, when the strainer 8 is detachably provided in the tube hole 6, solid substances such as raw dust which are not collected by the net basket 4 are collected by the strainer 8. .

[0011]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

The drainage device of the sink shown in FIGS. 1 to 3 is, in an embodiment of the present invention, an outer box body 2 having an open upper surface and a receiving portion 1 protruding from an inner peripheral surface of an upper end portion, and an outer peripheral edge of the upper end portion. The flange 3 extended to the upper part is mounted on and supported by the receiving part 1, so that the net basket 4 that is freely inserted into and removed from the outer box body 2 and the bottom surface 5 of the outer box body 2. The S-shaped trap 7 having the upper end opening connected to the tube hole 6 formed in 1.

The outer box body 2 is made of stainless steel and is formed into a cylindrical shape having an open top surface, and a tube hole 6 is formed at a substantially center of the bottom surface 5. The receiving portion 1 is provided on the inner circumferential surface of the upper end portion so as to project over the entire circumference. Further, a flange portion 16 is provided on the outer peripheral edge of the upper end over the entire circumference.

The net basket 4 is made of stainless steel similarly to the outer box body 2, and is formed slightly smaller than the inner size of the outer box body 2. A flange 3 extends around the entire outer periphery of the upper end, and the flange 3 is mounted on and supported by the receiving portion 1 of the outer box body 2 so that the flange 3 can be freely taken in and out of the outer box body 2. It is installed. A grip 17 having a substantially arc shape is rotatably provided on the upper end so that it can be easily taken in and out.

The S-shaped trap 7 is made of stainless steel similarly to the outer case body 2, and has an upper end opening welded to a pipe hole 6 formed in the bottom surface 5 of the outer case body 2 to be integrally connected to the outer case body 2. Has been done. A perforated seat 18 is formed in the vicinity of the tube hole 6 and a strainer 8 is detachably attached.

The drainage device of this sink is provided at the drainage port 12 formed in the sink 19 of the sinkage 11, and the collar box 20 projecting from the lower end of the drainage port 12 is provided with the outer box body 2 of the outer box body 2. The collar 16 is mounted and fixed, and the lower end opening of the S-shaped trap 7 is connected to the drain pipe 13. Then, the chrysanthemum rubber 10 is removably mounted on the flange 3 of the net basket 4 mounted on the outer box body 2.

In the drainage device of this sink, however, since the sealing water 15 is stored in the S-shaped trap 7 instead of in the outer box body 2, it causes slimy and dirty inside the outer box body 2. Bacteria and mold are less likely to be generated, and the inside of the outer box body 2 can be kept clean for a long period of time. Moreover, since the space for providing the bowl trap 9 is not required and the outer box body 2 can be made small, the storage portion 14 of the sink 11 formed below the sink 19 can be effectively utilized. Further, since the strainer 8 which is detachably installed in the pipe hole 6 collects solid matters such as raw garbage which are not collected by the net basket 4, solid matters such as raw garbage are drained. It is possible to suppress the flow into the drain pipe 13 as much as possible and prevent the drain pipe 13 from clogging.

The drainage device for the sink is not limited to the above embodiment, but the outer box body 2 and the S-shaped trap 7 are formed separately from each other by resin or the like and connected by a pipe joint or the like. Is also good.

[0019]

[Effect of device]

 As described above, in the sink drainage device of the present invention, since the S-shaped trap 7 is connected to the pipe hole 6 without protruding into the outer box body 2, the outer box body 2 does not need to be deepened to form a mesh. The basket 4 can be deepened to enhance the ability to collect garbage and the like. Moreover, since the sealing water 15 for blocking the odor rising from the drain pipe 13 is stored in the S-shaped trap 7 instead of in the outer box body 2, it causes slimy and dirty inside the outer box body 2. Bacteria and mold are less likely to be generated, and the inside of the outer box body 2 can be kept clean for a long period of time.

Further, when the strainer 8 is detachably provided in the tube hole 6, solid substances such as raw dust not collected by the net basket 4 are collected by the strainer 8, and thus the raw dust is collected. It is possible to prevent solid matters such as the like from flowing into the drain pipe 13 as much as possible, and to prevent the drain pipe 13 from being clogged.
