Abstract

(57) [Summary] [Purpose] The strainer, which is inserted and installed in the drainage port of the sink to capture dust in the drainage, improves the trapping ability and makes it difficult for dust to adhere to the bottom of the strainer and also cleans it. Make it easier. [Structure] A rib 2 is provided at the upper end, and horizontal and vertical ribs 3,
In addition to forming a drainage hole 5 of 2 mm ² or less in a mesh shape with 4,
A similar drainage hole 6 is also formed on the bottom surface, and from the lower end of the synthetic resin strainer body 1 to a location corresponding to 1/7 to 1/5 of the whole, gently bends from the bottom surface to the side surface without a drainage hole. The continuous corners 7 are formed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a strainer made of a synthetic resin, which is attached to a drainage port of a sink and captures kitchen waste such as vegetable waste and food waste that is washed away with the drainage.

[0002]

[Prior art]

Conventionally, this kind of strainer has a large number of drain holes 5'in a mesh shape with vertical and horizontal ribs 3 and 4 around a bottomed substantially cylindrical main body 1 provided with a collar portion 2 on the upper periphery as shown in FIG. In addition to the above, a number of drainage holes 6'having substantially the same shape were also formed on the bottom surface, and it was used by inserting it into the drainage port of the sink. However, the strainer individual draining hole 5 ', 6' for the magnitude of is ² about 5 to 10 mm, small dust can not be caught, flows with the waste water, is deposited in the trap unit in the waste water pipe malodorous It not only causes the above problems and causes clogging of pipelines, but also contaminates rivers and lakes into which wastewater flows, which is also a cause of environmental pollution. Therefore, as shown in FIG. 5, the pitch of each of the vertical and horizontal ribs 3 and 4 is narrowed, and the size of each drain hole 5 formed by both ribs 3 and 4 is set to 2 mm ² or less, and formed on the bottom surface. The drainage hole 6 to be used has the same size so that small dust can be captured.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional strainer, the size of the drainage hole is extremely small, so it is easy for clogging of dust, especially for dust adhering to the ribs near the lower end or the drainage hole, the lower end of the main body is almost at a right angle. In addition to the above, there was a problem that it was difficult to remove, the drainage property was lowered, and it was apt to be unsanitary. The present invention aims to solve these conventional problems.

[0004]

[Means for solving the problem]

In this invention, the size of each drainage hole is set to 2 mm ² or less, and from the bottom end of the strainer to the position corresponding to 1/7 to 1/5 of the whole, there is no drainage hole, and from the bottom surface to the side surface. The above-mentioned conventional problems were solved by making the corners gently continuous.

[0005]

[Action]

 The corners with a large radius of curvature at the bottom of the strainer and a little deeper serve to reduce clogging at the bottom of the strainer and to facilitate cleaning.

【Example】

FIG. 1 is a semi-longitudinal side view of the embodiment, FIG. 2 is a rear view thereof, and FIG. 3 is a cross-sectional view of a main part. As shown in the figure, the resin strainer of the present invention is formed integrally with a synthetic resin into a substantially cylindrical shape with a bottom having a flange portion 2 formed on the upper end as in the conventional case, and the side surface and the bottom surface have mesh-shaped drain holes 5 respectively. , 6 are formed. Reference numerals 3 and 4 denote vertical ribs and horizontal ribs for forming the drain holes 5, respectively. In this embodiment, both ribs 3 and 4 are formed with a width of 2 mm and a pitch of 3.4 mm. Therefore, the size of the draining hole 5 formed in both the ribs 3 and 4, 1.4mm × 1.4mm = 1.96mm ^2, and the formed substantially 2 mm ² or less.

Further, the lower portion of the strainer body 1 is formed to be gently curved, and a continuous portion from the side surface to the bottom surface is a rounded portion 7 having a radius of 10 to 20 mm. In addition, no rib or drain hole is formed on the side surface continuous with the rounded portion 7 from the lower end to a position corresponding to 1/7 to 1/5 of the strainer depth. This dimension is around 20 mm because the strainer depth is usually around 130 mm, which is the maximum value confirmed by experiments that there is no problem in drainage performance.

In the resin strainer of the present invention having the above-mentioned structure, the collar portion 2 at the upper end is engaged with the peripheral edge of the drainage port (not shown) of the sink so that the strainer can be immersed in the drainage port. It is attached and captures debris such as vegetable debris and food residues that are washed away with the drainage. Here, in the resin strainer of the present invention, since the size of each drain hole 5, 6 is as extremely small as 2 mm ² or less as described above, it is possible to sufficiently capture even small dust that could not be captured conventionally. In addition, since there are no drainage holes or ribs near the lower end, dust is unlikely to adhere, and the corners 7 are gently curved, so it is easy to put your fingers inside for cleaning and maintain them. Can be done very easily.

Although not shown in the illustrated embodiment, a rubber flap or the like is attached to the upper portion of the strainer to conceal the inside to maintain a good appearance and reduce odor. . In addition, when the strength of the main body is insufficient by narrowing the rib pitch and making the mesh fine, it is advisable to partially set the drain hole to a blind portion.

[0010]

[Effect of device]

 As described above, the resin strainer for the sink of the present invention has a drain hole size of 2 mm. ² Even though small dust can be captured because it is below, there are no drain holes or ribs on the bottom of the side of the strainer, so it is difficult for dust to adhere, and the corners at the lower end are gently curved for easy cleaning. It is hygienic, and has an unprecedented excellent effect that it can reduce adverse effects on the environment due to drainage without impairing handling such as maintenance.
