Description

[0001] OPENING-CLOSING DEVICE FOR SINK DRAIN HOLE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sink opening and closing device for opening or closing a sink drain hole provided in a sink ball, filling a sink ball with water, or discharging water filled in a sink ball.

In general, a kitchen sink is provided with a sink ball for washing dishes. A drain hole is provided at the bottom of the sink bowl, and a drain pipe is formed to connect the drain hole to the sewer.

The drainage port is provided with a filtering net so that the food wastes discharged through the drainage port are caught by the screen and only the water is discharged to the sewerage through the drainage pipe. In order to prevent the odor coming from the drainage port, An opening / closing cap for closing the upper end of the drain hole is used.

Such an opening and closing stopper is disclosed in Japanese Patent Laid-Open Nos. 10-2008-0076231 and 20-0333071.

Such a conventional opening and closing cap is a passive type in which a user holds the opening and closing cap and puts up the sink drain hole or removes the opening and closing cap so that the drain opening is opened.

However, such a passive type opening and closing plug is troublesome because the user has to open and close the drain opening by moving the drain opening directly. To open the drain opening, the opening and closing plug should be placed on the sink after it is separated from the drain. Therefore, it was not easy to find a place to put down, and there was a disadvantage that it easily lost the opening / closing cap.

In addition, when the dishwasher is separated from the opening and the drain hole is opened, the drain hole is completely opened, so that not only the food waste is discharged to the sieve through the drain hole but also the food items such as spoons, And a problem of entering the screen with a small amount of water.

On the other hand, a conventional one-touch pop-up valve has been developed in which a cap is popped up by a pushing operation of a user and the opening and closing cap is closed when the user presses the cap again. For example, in Japanese Patent Laid-Open Nos. 10-1468810 and 10-0678385.

However, the opening and closing apparatus of such a sink is not a structure applicable to a drain of a sink. That is, since there is no constitution of the cylindrical sieve mesh installed in the drain hole in the sink, there is a limit in applying the opening and closing device of the sink to the drain hole of the sink.
