Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drainage device for a washbasin.

Washbasins that are configured to store water by installing a lid on the bottom to block the drain have the disadvantage that even when the lid is opened, the opening area is generally small, resulting in poor drainage efficiency. It has the disadvantage that it easily generates vortices and generates a ``go'' noise as air is sucked in. Drainage efficiency can be improved by making the drain hole larger and covering it with a larger lid, but this will increase the water pressure on the lid and cause the lid to strongly stick to the drain hole. For this reason, when opening the lid, the user has to lift the lid forcefully, making it difficult to operate since the detergent may slip on the user's hands.

In view of these conventional drawbacks, the present invention provides a main lid that can be attached vertically and detachably to the main drain port of the main body of the device fitted to the bottom of the washbasin, and a sub-drain port is provided in the center of the main cover. Then, a sub-lid for opening and closing the sub-drain port is attached so as to be able to be moved up and down, a knob is attached to the top surface of the sub-lid, and a receiving bracket is attached to a connecting rod hanging down from the bottom surface of the sub-lid. The receiving bracket is positioned opposite the lower edge of the main lid at an appropriate distance, and a locking member is provided on the inner peripheral surface of the main body of the device, and the knob is lifted to raise the receiving bracket to a high position. Provided is a drainage device for a washbasin configured such that the main drain port and the sub drain port are held in an open state by holding the main drain port and the sub drain port in an open state by holding the main drain port and the sub drain port in an open state by holding the main drain port and the sub drain port in an open state. The drain can now be opened and the lid can be opened in two steps, reducing the force required to open the lid. Drainage efficiency is also improved by draining water from the main drain and sub-drain. The lid can be kept open even when the lid is not held by hand, and drainage noise can be suppressed.

An embodiment of the present invention will be described below with reference to the drawings. The main body 1 of the device is formed of metal or synthetic resin into a substantially cylindrical shape, and the inner periphery of the upper opening edge thereof is formed into an inverted conical cylinder shape, and a main drain port 3 is provided, and a flange 4 is formed on the outer periphery of the opening edge. , fit the device main body 1 into a hole 6 made in the bottom surface 5 of the wash basin, screw the fastening ring 7 around the body of the device main body 1, and attach the gaskets 8, 9.
The main body 1 of the apparatus is watertightly fitted into the extraction hole 6 with the intervening hole 6 interposed therebetween. 10 is a drain pipe connected to the lower end opening of the main body 1 of the apparatus. 11 is a main lid which is generally funnel-shaped and has a sub-drain port 12 in the center thereof, and an elastic ring 13 fixed to the outer periphery of the main cap is watertightly attached to the main drain port 3. The main drain can be opened and closed. Reference numeral 14 denotes a sub-lid made of rubber that is attached to the sub-drainage port 12 so as to be able to move upwardly and removably.A connecting shaft 15 is inserted through the center of the sub-lid, and a knob 16 is attached to the upwardly projecting end of the connecting shaft 15. do. The receiving bracket 17 is the upper half part 17a
It has an inverted bowl shape in which the lower half part 17b is formed into a large-diameter cylindrical shape and the lower half part 17b is formed into a small-diameter cylindrical shape, and water permeable holes are provided in the intermediate horizontal surface part 17c and the bottom part 17d so that water can freely pass through. An engagement piece 17e that protrudes in four directions around the outer periphery is formed at the upper opening edge of 17a. The lower end of the connecting shaft 15 is inserted through the center of the bottom portion 17d of the receiving fitting 17, and the nut 18 is fastened, so that the receiving fitting 17 is mounted so as to be positioned opposite to the lower edge of the main lid 11 with a gap g in between. . Reference numeral 20 denotes an annular locking member that is received on a step 19 formed on the inner periphery of the device main body 1, and the upper edge of the locking member is connected to the high portion 20a.
are formed around the four sides so as to have a step difference with the lower part 20b, and protrusions 2 for preventing slipping are provided on both shoulders of each high part 20a.
1 are formed respectively. Reference numeral 22 denotes a wire mesh strainer for catching loose hair, etc., and the strainer has a flange 23 provided around its upper edge and a stepped portion 24 further protruding from the inner peripheral surface of the lower end of the stepped portion 19. It is installed in the device body 1 by being locked.

In the drainage device configured in this manner, if the knob 16 is picked and the sub-lid 14 is pulled up a little from the fully closed state shown in FIG. 1, the sub-drain port 12 will first open as shown in FIG. The accumulated water in the washbasin begins to be discharged from the sub-drain port 12. At this time, the receiving metal fitting 17 that is integrated with the sub-lid 14 is also lifted at the same time, so if the knob 16 is further pulled up, the receiving metal fitting 17 is further lifted and the bottom surface of the receiving metal fitting 17 is lifted.
7d comes into contact with the lower edge of the main lid 11 and lifts the main lid 11 together with the holder 17. For this reason, as shown in FIG. 4, the main drain 3 is opened and the main drain 3 is opened.
Drainage has also begun. Therefore, by rotating the knob 16 by 45 degrees in a horizontal plane and aligning the engagement piece 17e of the receiving metal fitting 17 with the high part 20a of the locking member 20 and holding it in the high part 20a, even if the hand is released, the secondary water drains. Both the port 12 and the main drain port 3 can be kept open.

According to this drainage device, the opening operation is performed in two steps such that by lifting the knob, first the small-diameter sub-drain port 12 is opened, and then the large-diameter main drain port 3 is opened. Since the water pressure inside the basin is distributed between the sub-lid 14 and the main lid 11 when water is stored,
The force required to initially pull up the sub-lid 14 is small, and after opening the sub-drain port 12, the main drain port 3 is opened and the water in the basin is drained from both drain ports, so the total opening is The area can be increased, drainage efficiency is improved, and accumulated water can be drained in a short time. Further, by holding the receiving metal fitting 17 on the locking member 20, the main drain port 3 and the sub drain port 12 can be held in an open state, so it is not necessary to hold the knob 16 by hand during draining. Furthermore, during drainage, the main drain port 3 opens in an annular manner around the outer circumference of the sub-drain port 12, so a vortex would easily occur if there was a single drain port in the past, but in this case, the center of the vortex cannot be determined. Because there is no vortex, it is difficult to generate vortices, and air is not sucked in from the center of the vortex, so there is almost no noise.

As explained above in the embodiments, the drainage device of the present invention is extremely useful, having many advantages such as reducing the force required to open the lid when water is stored, improving drainage efficiency, and eliminating drainage noise. It is.
