Abstract

PURPOSE:To keep the beauty of the inside of a sink by preventing drop of small flatwares. CONSTITUTION:A cover 10 installed on the top surface opening portion 13 of a drainage device 8 installed in a drain hole 7 of the bottom portion of a sink 6 comprises a doughnut-type support cover 15 and a disc-like rotary plate 16 provided in the inner hole of the support cover 15. An integrally formed pivotal support shaft 18 symmetrically on the peripheral edge of the rotary plate 16 is rotatably installed on the side surfaces of the inner hole of the support cover 15, and the rotary plate 16 is formed in such a manner as to turn on the pivoting support shaft 18. Accordingly, at the time of washing flatwares, the cover 10 is put in the locking state so that small flatwares can be prevented from dropping in a garbage basket. At the time of letting cooking garbages flow in the garbage basket in the drainage device, the cover is released from the locking state to be freely reversed, so that the cover 10 is rotated by the weight of cooking garbage to let the cooking garbage naturally drop in the garbage.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage system for a sink.

0002

2. Description of the Related Art As shown in FIG. 4, a conventional drainage device of this type has a plurality of thin plate tongue-like pieces 3 in an upper opening 2 of a drainage device 1, and is made of an elastic material such as rubber. The garbage basket 5 was provided with a lid 4 and a garbage basket 5 disposed below the lid 4.

0003

[Problems to be Solved by the Invention] In such a conventional structure, the lid body 4 has a plurality of tongue-like pieces 3 made of an elastic material. They tend to hang downward, and when cleaning tableware and utensils, small utensils such as spoons easily fall from the lid 4 into the garbage basket 5 below. In addition, the elasticity of the tongue-shaped piece 3 deteriorates over time, and the tongue-like piece 3 remains curved downward, making it unsightly in terms of appearance since the garbage in the garbage basket 5 below is visible.

[0004] The present invention is intended to solve these problems, and aims to provide a drainage device that prevents small utensils from falling and maintains the beauty of the inside of the sink.

[0005]

[Means for Solving the Problems] The drainage device of the present invention is provided with a lid body having a large number of drainage holes at the top opening of the drainage device attached to the drain port of a sink, and this lid body is moved up and down by a pivot shaft. The drainage device is provided so as to be reversible, and the opening of the drainage device is locked in a closed state by a stopper means.

[0006]

[Function] The drainage device of the present invention is provided with a lid body having a large number of drainage holes at the upper opening of the drainage device and which can be turned over from a locked state in which the opening of the drainage device is closed by means of a pivot shaft. Therefore, when cleaning tableware, etc., by locking the lid, it is possible to prevent small tableware from falling into the garbage basket. Also, when pouring cooking waste into the garbage basket in the drainage system,
If the lid is released from the locked state and can be turned over, the lid rotates under the weight of the cooking scraps, allowing the cooking scraps to naturally fall into the garbage basket.

Further, after cooking, by locking the lid with the opening of the drain device closed, it is possible to hide dirt inside the drain device and improve the appearance.

[0008]

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, reference numeral 6 denotes a sink disposed on the worktop 21 of the sink 20, and the sink 6 has a drainage hole 7 bored in its bottom. Reference numeral 8 denotes a drainage device attached to the drainage hole 7, and the drainage device 8 is composed of a drainage main body 9, a lid body 10, a garbage basket 11, and an odor-proof lid 12. The drainage main body 9 is formed into a cylindrical shape having an opening 13 on the upper surface and a drain pipe 14 on the lower surface. A lid 10 is attached to the upper opening 13. The lid body 10 includes a donut-shaped support lid 15 and a disc-shaped rotary plate 16 provided in the inner hole of the support lid 15. The rotating plate 16 has a large number of drainage holes 17, and a pair of pivot shafts 18 are symmetrically formed integrally with the peripheral edge. This pivot shaft 18
is rotatably attached to the side surface of the inner hole of the support lid 15, and the rotary plate 16 is formed to be rotatable about a pivot shaft 18. The support lid 15 is made of an elastic material, and has a pair of locking portions 19 symmetrically protruding from the side surface of the inner hole. The rotating plate 16 is locked to the locking portion 19.

In the above structure, the top opening 13 of the drain device 8 is provided with the lid 10 which has a large number of drainage holes 17 and is rotatable from the locked state by the pivot shaft 18, so that tableware etc. When cleaning the lid body 1, as shown in FIG.
By locking the rotary plate 16 of 0 to the locking portion 19 of the support lid 15, small eating utensils can be prevented from falling into the garbage basket 11. Furthermore, when pouring cooking scraps into the garbage basket 11 in the drainage device 8, as shown in FIG. The cooking scraps can naturally fall into the garbage basket 11. To release the lock of the rotary plate 16, use the support lid 15.
Since the locking portion 19 is made of an elastic material, the rotating plate 1
It can be easily released by pressing 6 downward with your hand.

Furthermore, by locking the lid 10 after cooking, it is possible to hide the dirt in the drain device 8 and maintain the beauty of the interior of the sink 6.

[0012] In the above embodiment, an elastic locking portion is used as the stopper means of the lid body 10, but the present invention is not limited to this, and other stopper means for temporary locking may also be used. be.

[0013]

[Effects of the Invention] As is clear from the above description of the embodiments, according to the present invention, the upper opening of the drainage device has a large number of drainage holes, and the opening of the drainage device is closed by a pivot shaft. Since the lid body is provided so that it can be turned over from the locked state, when cleaning the food utensils, etc., by placing the lid body in the locked state, small eating utensils can be prevented from falling into the garbage basket. In addition, when pouring cooking scraps into the garbage basket in the drainage system, if you release the lid from the locked state and allow it to flip freely, the lid will rotate due to the weight of the cooking scraps and the cooking scraps will naturally flow into the garbage basket. It can be dropped inside.

[0014]Furthermore, if the lid is locked with the opening of the drain device closed after cooking, it is possible to hide the dirt inside the drain device and improve the appearance. be.
