Sink drainage {DRAINING APPARATUS FOR WASHSTAND}

The present invention relates to a drainage device for a sink, and more particularly, it is possible to prevent the contamination of the surrounding area by outflow of water on the drain, and of course, it is possible to easily wash the strainer filtering the foreign matter. It relates to a sink drain.

In general, the sink is installed so that the user can wash the hands or face in the bathroom or bathroom of the building.

The wash basin is provided with a water pipe while being spaced apart a certain distance from the bottom to one side of the wall of the bathroom or bathroom, and also in order to drain the water from the sink should be provided with a drain trap and a drain connected to the sewer pipe.

Referring to FIG. 1, a conventional drainage device for a wash basin may include a sink body 20 made of a ceramic material, a drain pipe 21 inserted into a drain hole at a lower end of the sink body, and an outer diameter of the drain pipe 21 and a bottom of the vane body.

To this end, it is not possible to perform a quick wash due to the operation of separating each other, as well as very inconvenient to do by the consumer directly.

In this case, when the control bar 32 and the transfer rod 31 are simply straddled so that the guider 11 can be easily separated, the control bar 32 is separated from the transfer rod 31 and cannot operate. And there is a concern that the control bar 32 and the entire guider 11 is lost in the construction process.

Fourth, since the overall length of the control bar 32 of the guider 11 is fixed, when the assembly error and the error of the sink body 20 and the length error occurs on the drain pipe 21, the transfer rod 31 By not adapting to the error when the assembly is completed, a fatal problem that prevents the flow of water through the water stopper 10 occurs.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

2 is a cross-sectional view of the drainage device for the sink according to the present invention, FIG. 3 is an exemplary view for explaining the structure of the guider shown in FIG. 2, and FIG. 4 is a structure of the control bar shown in FIG. It is an illustration of a side view and a bottom view for demonstrating this.

As shown in the present invention, the sink for drainage according to the present invention includes a sink 100, a drain pipe 200, a key box 300, a sealer 400, a guider 500, And a control bar 600, a sieve 700, and a cover 800.

First, the wash basin 100 is formed of a pottery (陶器) material, is installed in the bathroom or toilet, and in particular, the drainage port 110 is formed to extend a predetermined length in the lower center surface.

The drain pipe 200 is inserted into the drain hole 110 of the sink 100, the upper outer peripheral surface of the flange 210 is formed so as to form the same plane as the bottom surface of the sink 100, the drain hole 110 The thread 220 is formed on the lower outer circumferential surface exposed to the lower portion.

The key box 300 is positioned so as to be in direct communication with the lower portion of the drain pipe 200, the upper outer peripheral surface of the flange 310 is formed extending, the inner peripheral surface of the screw thread 320 to be screwed with the drain pipe 200 Is formed.

In addition, the lower one side of the connecting pipe 330 is formed integrally extending in the substantially horizontal direction, the connecting pipe 330 is inserted into the horizontal adjustment rod (2) having a sealing (1).

The sealer 400 is located between the lower surface of the drain 110 of the sink 100 and the flange 310 of the key box 300, and the key box 300 is screwed to the drain pipe 200. By close contact with the lower edge surface of the drain 110 performs a function to block the leakage (漏 水).

At this time, the shape of the sealer 400 is preferably formed so that the portion in close contact with the lower edge surface of the drain port 110 is relatively protruding, and in particular, the protruding portion is formed to be inclined downward as the inward direction. something to do.

The guider 500 is installed to be slidable up and down along the inner surface of the drain pipe 200, and the water stopper 510 is coupled to the upper end to drain and block water, and the protruding jaw 520 is extended to the lower end. do.

At this time, the guide groove 521 of a predetermined depth is formed on the protruding jaw 520 in the up and down directions.

The control bar 600, one end is slidably coupled along the guide groove 521 of the guider 500, the other end is coupled to one side end of the horizontal adjustment bar (2), It performs the function of moving the guider 500 up and down by interlocking.

The sieve 700 is coupled to the protruding jaw 520 of the guider 500 while penetrating through the control bar 600, and performs a function of filtering foreign substances, such as hair, on the discharged washings.

Finally, the cover 800 is coupled to the outer end of the connecting pipe 330 extending on one side of the key box 300, is coupled via the spring (S) to elastically support the horizontal adjustment rod (2). .

On the other hand, installing one end of the control bar 600 in the guide groove 521 formed on the protrusion jaw 520 of the above-described guider 500 to move up and down is the size error of the sink 100 and each component This is to compensate for assembly errors that may occur during assembly.

However, if it continues to move in the combined state, it is impossible to perform the function of draining and blocking the drain through the water stopper 510.

Therefore, after compensating for the assembly error, the control bar 600 should be firmly supported to block the movement along the guide groove 521.

For this purpose, a plurality of cutout grooves 522 are formed on the outer circumferential surface of the protruding jaw 520 so as to communicate with the guide grooves 521, a screw thread 523 is formed on the outer circumferential surface, and a protruding jaw on the inner circumferential surface of the strainer 700. The thread 710 is formed to be screwed to the 520.
