Description

  The present invention relates to a drain outlet lid attached to a drain outlet provided in a sink of a sink so as not to prevent drainage to the drain outlet.

  Conventionally, there has been a drainage lid of this type as shown in FIG. The drainage lid 20 is formed by cutting a disk-shaped rubber plate radially from the center hole 21 provided at the center portion of the disk-shaped rubber plate, that is, a plurality of elastic tongue pieces 22. The strainer 10 is attached so as to close the upper surface of the strainer 10 by fitting into a stepped surface portion 10a on the inner periphery of the strainer 10 attached to a drain outlet formed in the bottom surface 8 of the sink. In the drain cover 20, the elastic tongue pieces 22 are elastically held almost horizontally, so that a dust collecting net cage (not shown) housed in the strainer 10 cannot be seen from the outside. When using the sink for washing, etc., each elastic tongue 22 is bent downward by the flowing water pressure flowing into the drain, and the washed-out leftover food and vegetable waste are smoothly put into the mesh basket. It comes to fall.

  Moreover, as a thing formed other than rubber | gum, there exists a thing made from the synthetic resin shown, for example in Unexamined-Japanese-Patent No. 7-286349. As shown in FIG. 8, a covering portion 32 including an upward inclined piece 32 a protruding obliquely upward and a downward inclined piece 32 b protruding obliquely downward is provided inside the outer edge portion 31. An inflow port 33 through which drainage flows is formed between the inclined pieces 32a and 32b. The drain port lid 30 is attached to the drain port of the sink via the strainer 10 by fitting to the stepped surface portion 10a formed on the inner periphery of the strainer 10 in the same manner as described above. Yes.

  Here, the drain outlet 30 made of synthetic resin is attached so that the downward inclined piece 32b is positioned on the back side of the sink (right side in FIG. 8), that is, the upward inclined piece 32a is located on the side of the person using the sink. ing. Therefore, when washing or the like standing in front of the sink, the net basket provided in the strainer 10 or the dust trapped inside the strainer 10 is blocked by the upward inclined piece 32a of the drainage lid 30 and cannot be seen. , A hygienic impression is given without causing discomfort to the user.

  Further, the waste water and the dust flowing along with the waste water are guided to the net cage 7 in the strainer 10a through the downward inclined piece 32b provided on the rear side (right side in FIG. 8) of the drain port lid 30. ing. In addition, at this time, the washware such as tableware is caught between the semicircular arc-shaped downwardly inclined piece 32b or the downwardly inclined piece 32b and the upwardly inclined piece 32a, and does not easily fall into the mesh basket 7. Yes.

  In FIG. 9, reference numeral 11 indicates a drain pipe communicating with the lower end of the strainer 10.

  In the conventional drain port lid described above, the one shown in FIG. 9 uses the elastic force of the elastic tongue piece made of rubber to close the drain port, so that its elastic recovery gradually with use. If the force is weakened and the tip of the elastic tongue hangs down, it may not return.In this case, the net cage that has captured the dust is exposed so that it can be seen from the outside, and is displayed to the user. There was a problem of giving an unpleasant and unhygienic impression.

  In addition, since the elastic tongue is easily bent downward by running water or the like, there is a drawback that small items such as a spoon easily fall into the net basket when washing. Furthermore, the drain cap is made of rubber, so despite its high cost, it is deteriorated relatively early by being exposed to chemicals such as hot water and detergent, resulting in poor durability. There was also a point.

  Although the problems shown above are considerably improved, the orientation shown in FIG. 8 is fixed, so the orientation of the strainer is fixed. It was exposed and not only was unsightly, but also the direction of drainage changed, so there was a possibility that the drainage performance would deteriorate.

  In addition, the drain cap covers the inside of the strainer in an invisible manner, and the downward sloping piece is curved downward greatly so that the waste can be smoothly guided along with the running water into the net cage. The inflow opening between the two and the opening was large, and it was not possible to say that there was no possibility that small items such as spoons would fall into the net for catching garbage from this inflow when washing.

  Furthermore, in this drainage lid, the water accumulated on the sink is once guided to the rear of the drainage lid, and then flows to the front side through the downward inclined piece, so the flow of drainage is not smooth, Washing away leftovers and vegetable scraps was not done smoothly. And even if it falls into the net cage, there is a possibility that these wastes collect on one side of the net cage and hinder its drainage.

  Furthermore, since this drainage lid is asymmetrical, it is likely to be deformed due to distortion or the like, and when it is deformed, there is a possibility that the drainage port cannot be closed well as it was intended.

  This invention makes it a subject to solve the problem which the drain outlet cover of the said conventional sink had.
