Description

Sink drainage switch {DRAIN DEVICE FOR WASHSTAND}

The present invention relates to a drainage switchgear for a wash basin, and more particularly, to a drainage switchgear for a wash basin with excellent drainage performance while reducing costs.

The wash basin is installed on one wall of the toilet so that the hands and face can be washed in the restrooms of the homes, government offices, and other buildings. In general, the bottom of the sink is provided with a drain opening and closing device for fresh water or drainage.

1 and 2 is a view schematically showing the configuration of a conventional drainage switchgear.

As shown, the drain opening and closing device is installed through the bottom surface of the sink 6, which serves as a fresh water space of the water.

The drain opening and closing device includes a first body 2, a second body 13, a stopper 5, a seesaw rod 3, a lifting rod 27, and the like.

When the user pulls the lifting rod 27 upward, the seesaw rod 3 is interlocked to pull the stopper 5 downward to close the drainage. On the contrary, as shown in FIG. 1, when the user pushes the lifting rod 27 downward, the seesaw rod 3 is interlocked to push the stopper 5 upward to drain the water.

However, the conventional drainage opening and closing device has the following problems.

This is due to the nature of busy modern people, rather than waiting for a predetermined amount of water is to wash the face or wash the face of the water in the state is becoming common. In particular, in public toilets, the use of fresh water in the sink for hygiene is very rare, and the effectiveness of the drain switchgear will be extremely low.

As such, even though there is little utility, the conventional drainage switchgear has a problem that the structure is complicated, there are many parts, and the assembly process is cumbersome in terms of cost and productivity.

In addition, because the lifting rod 27, the seesaw rod (3), etc., the work must be performed in the upper and lower sinks, and during installation, maintenance or cleaning work, the work is difficult and takes a lot of time, difficult to install and maintain Had a problem. As a result, it was difficult for the general public to simply repair or clean the drain switch.

In addition, as shown, since a part such as the seesaw rod 3 should be positioned in the middle of the drainage path, foreign substances such as hair and fibers are caught and deposited to prevent smooth drainage of the water, and the cleaning is repeated at appropriate intervals. If not, there was a problem that frequently occurs until the drainage blockage. In this case, in order to remove the accumulated foreign matter, the dismantling operation such as dismantling the seesaw rod 3 and the like is required, but the dismantling operation is not easy due to the complicated structure.

Therefore, in order to solve the problem of clogging the drainage, various design changes of the drain opening and closing device have been attempted. However, most of these drain opening and closing devices are focused only on improving the drain opening and closing device of FIG. 2 described above, and an attempt to approach a more fundamental solution is difficult to find.

Some of the improved drain switchgear solved the problem of foreign matter jamming by changing the structure to solve the foreign matter jamming phenomenon, while the number of parts and the structure became more complicated.
