Abstract

PROBLEM TO BE SOLVED: To drop garbage into a strainer via the rotation of a cover, to clean the inner periphery of the strainer with drainage and to suppress clogging by providing the rotatable cover on the strainer, and forming a gap for drainage on the outer periphery of the cover. SOLUTION: A receiving ring 1 is provided on the drain inlet of a sink, the rotary shaft of a disk-shaped cover 2 is fitted into a groove formed on the receiving ring 1 to support the cover 2 rotatably and automatically recoverably to a horizontal state, a fixed gap is formed between the cover 2 and the receiving ring 1, and a strainer is arranged below the cover 2 and is connected to a drain pipe. The inner periphery of the receiving ring 1 is tapered, and the upper face of the cover 2 is also tapered. The garbage in the sink is dropped to the bottom section of the strainer via the rotation of the cover 2, and the drainage in the sink flows down along the inner periphery of the receiving ring 1 and flows down along the inner surface of the strainer from the gap between the receiving ring 1 and the cover 2. The inner surface of the strainer is cleaned by the drainage flowing down in the strainer, and clogging can be suppressed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to kitchen equipment and a lid attached to a strainer (net) for filtering residue such as kitchen waste at a drain of a sink.

[0002]

2. Description of the Related Art In most cases, generally used lids have a star-shaped cut in a thin film stretched on the inside of a rubber ring, and a new idea has been found in about 250 studies published in the prior application IPC classification A47B77 / 06. can not see.

[0003]

The rubber cover used in the prior art has a central part with a star-shaped cut in the opening of the thin-film portion, and drains and drains the residue by a filter provided at the end thereof. Although the residue is collected and collected, the residue is repelled by the drainage flowing from the center and adheres to the inner wall of the strainer, thereby accelerating the clogging of the strainer, and producing slimey sticks due to the propagation of fungi. It is unsanitary, causing clogging and stench.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a receiving ring having a ring-shaped groove provided as a bearing by being fitted with a shaft of a lid at both poles on a center line on the same plane side is provided. A disk with an outer shape that can maintain an appropriate gap, with a lid provided with a single support shaft at both poles on the center line on the outer periphery near one side, and the bearing groove of the receiving ring and the lid shaft are fitted. At the same time, cover the inlet of the residue filter installed at the sink drain.

The inner shape of the receiving ring is formed to have a semicircular round shape or a substantially triangular shape with a slope in a sectional view, and in any case, the small inner diameter is equal to or somewhat larger than the inner diameter of the strainer. Make it large.

[0006]

[Function] The lid combined with the receiving ring is rotated by the weight of the residue and drainage to open the inlet, and the residue and drainage flow into the strainer, and the axis of the lid is offset to one side. Therefore, it is restored to the original horizontal state, and the drainage flows down the gap between the lid and the receiving ring along the inner surface of the filter and flows down. Rinse away any germs and germs.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings of the embodiment, FIG.
2 represents a flat surface of the receiving ring 1 in an assembled state, and a shaft 2a of the lid 2
And the groove 1a of the receiving ring 1 are fitted (see FIGS. 2 and 3).
The cover 2 rotates about a shaft 2a, and a gap 4 is provided between the cover 2 and the receiving ring 1, and a constant gap 3 is maintained at a seat 2b at the base of the shaft 2a.

FIG. 2 shows a cross section of the receiving ring 1 according to the second aspect, and the inside is tapered and inclined downward.

FIG. 3 shows a single support shaft 2a provided at both poles on the center axis near the upper surface on the side surface of the lid 2, and a receiving ring at the base thereof.
FIG. 4 shows a side view of FIG.

FIG. 5 shows a cross section of the receiving ring 1 according to the third aspect, in which the inside is rounded in a substantially semicircular shape.

FIG. 6 shows a state in which the lid 2 is attached to the sink drainage port, and when the residue and drainage flow, the lid 2 rotates about the shaft 2a as a fulcrum to open the inlet and returns to horizontal when the residue drops.

[0012]

According to the present invention, the drainage drains from the opening between the receiving ring and the lid and flows down along the inner surface of the strainer, so that the surface of the strainer is washed and the residue is flushed to the lower part to remove the residue and various bacteria. , Which has a great effect on suppressing clogging of the strainer.

Further, by making the inside of the receiving ring substantially semi-circular or inclined, the flow of drainage can be easily transmitted on the inner surface of the strainer.
