Description

[Detailed Description of the Invention] This invention relates to a sink drain device that connects to the drain hole of the sink.

Traditionally, the stop valve on a sink is only used when fitting into the drain hole and storing water in the aquarium, and it is usually removed, so you have to look for it when you need it, or it is lost and useless. Things tended to happen.

This is believed to be due to the fact that if a conventional water stop valve is left in a water tank, it gets in the way of kitchen work, while if it is placed on a table top, it impairs the sense of cleanliness and there is a risk of people getting confused.

Therefore, it is possible to recess the housing part of the water stop valve into the aquarium or table top, but this method is rarely adopted because it has fatal drawbacks such as complicated structure, time-consuming processing, and loss of aesthetics. The reality is that there is not.

This invention was devised in view of the above-mentioned drawbacks, and relates to a drainage device in which the stop valve is always facing the drain hole, and the drain hole can be opened and closed by rotating it as necessary. It is.

In the following, a description will be given based on the illustrated embodiment. Reference numeral 1 is a water stop valve, which has a knob 2 protruding from the upper part of its main body, and an appropriate number of legs 3 (in the illustrated example) located at the lower part slightly inward from the periphery. 4 bottles)
The backing 4 is made to hang down and a backing 4 is attached to the periphery of the lower surface.

Reference numeral 5 denotes a drain hole fitting, which is inserted through the backing into the hole edge of the drain hole of the water tank of the sink and is secured by tightening it with a nut from the bottom. , be sure to set up traps as necessary.

A step 7 is provided at the upper end of the inner periphery of the drain hole fitting 5 so that the main body of the water stop valve 1 can be fitted thereinto, and the leg 3 of the water stop valve 1 enters into the step 7 following this step 7. A slit 8 is provided.

Reference numeral 9 denotes a stepped portion that locks the collar at the upper end of the knitted basket 6.

In the drainage device according to this invention having the above configuration,
When the drain hole 1 is not used, that is, when the drain hole is left open, the legs 3 are placed on the stepped portion 7 of the drain hole fitting 5.

Then, a gate-shaped opening is formed between the water stop valve 1 and the drain hole fitting 5, and the wastewater containing kitchen waste flows down from there.

Next, when using the stop valve 1 to store water in the aquarium, all you have to do is hold the knob 2 and turn it so that the leg 3 enters the slit 8 of the drain hole fitting 5 and push it in.

To explain an embodiment included in this invention although not shown in the drawings, first, in order to make the stopcock 1 watertight, in the illustrated embodiment, a backing 4 is attached to the periphery of the lower surface of the main body. Alternatively, a ring-shaped backing may be fitted around the main body, or a ring-shaped backing may be fitted around the main body and the drainage hole fitting 5.
The circumferential side wall extending from the upper end to the step portion 7 may be sloped.

With such a configuration, the leg 3 of the water stop valve 1 is allowed to hang flush with the periphery of the main body, and at the same time, the step 7 of the drain hole fitting 5 is narrowed to continuously form the slit 8. Can be done.

Next, it is also possible to provide a groove on the stepped portion 7 for locking the tip of the leg 3 to prevent the water stop valve 1 from being washed away or rattled by drainage.

Further, in the illustrated embodiment, a garbage container is shown as the drain hole fitting 5, but the present invention is of course not limited to this.

As mentioned above, the water stop valve according to this invention is always fitted into the drain hole fitting and fulfills its original role of stopping water when necessary, so there is no inconvenience like searching for it or losing it as in the past. It will be resolved in .

When not in use, the stop valve will be located above the drain hole, but the water normally flows down from the edge of the hole, so the stop valve does not interfere with drainage, and the drain hole is generally located at the corner of the bottom of the tank. Since it is installed in the kitchen, it does not get in the way of kitchen work.

In addition, this idea does not involve any major changes to the conventional one, so it does not cause an increase in unit prices.
