Description

[Detailed explanation of the idea] The present invention relates to improvements in drain valves.

More specifically, the present invention relates to a drain valve that can store water up to a certain height in a kitchen washing area, a washroom, a bathhouse washing area, a footwashing area, etc., and can drain water stored above that level.

Conventional drain valves are shaped like rubber or synthetic resin and block the drain hole of the drain plug, like the drain valve in a washroom.Once a certain amount of water has been stored, a separate valve installed above the water tank is closed. The water was to be drained from the drainage hole.

The water storage method using such a drain valve requires a separate drain hole to be provided in the water storage tank, which is not only extremely inconvenient but also difficult to clean the drain hole.

It is also known that when a drain valve is fitted to a drain plug, such as in a kitchen washing area, there is a weight part that protrudes below the drain valve, and this weight part blocks the drain hole of the drain valve. However, this is inconvenient because it cannot store a certain amount of water, and if you are not careful, water will spill from the top of the washing area.

Furthermore, the washing area in the bathhouse cannot store water, and only has a perforated plate placed in the drainage hole to prevent large items or garbage from flowing out with the drainage.

The present invention provides a drain valve that eliminates the above-mentioned inconveniences and inconveniences, and allows a certain amount of water to be stored and also to be drained with one drain valve.

It also provides a drain valve that can immediately drain water without storing water.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 is a water-impermeable soft material such as rubber or plastic, and is attached to either the outer or inner surface of the peripheral wall of the drain valve 2.

As shown in FIG. 3, the soft material 1 attached to the inner surface of the drain valve 2 is provided with an inner frame 3, and is firmly fixed by the inner frame 3.

Note that the inner frame 3 may be made of a spring, a metal tube, or a hard plastic, and the inner frame 3 may extend below the drain valve 2 to form the bottom wall 4, and may be fixed with a screw, a split pin, or the like.

A drainage hole 10 provided in the upper part of the inner frame 3 is provided so as to be openable and closable by an opening/closing device.

Then, a drain hole 7 is bored in the inner frame 3 so as to match the ice drain hole 6 provided in the bottom wall 5 of the drain valve 2.

The drain hole 10 coincides with the drain hole 8 bored in the soft material 1, and the hole of the drain hole 8 is bored at a position corresponding to the upper part of the drain plug 9.

Note that the soft material 1, which does not have an inner frame 3 and is attached to the outer surface of the drain valve 2, is held between the drain plug 9 and the drain valve 2, as shown in FIG. 2, to prevent the soft material 1 from coming off. Therefore, the lower end extends below the drain valve 2, and the bottom wall 5 of the drain valve 2
It may be secured with a screw or a split pin 11.

A drain hole 12 is bored in the drain valve 2, and the drain holes 8 and 12 coincide to drain water.

Drain valve 2. The drain hole 12 may be opened and closed using an opening/closing device as shown in FIG.

For example, hook-shaped frames 13 are provided in two stages, upper and lower, and the frames 13, 13
A shielding plate 14 is slidably provided in between, and drainage holes 15 are bored in the soft material 1 at positions corresponding to the plurality of ice drainage holes 12.

Therefore, by sliding the shielding plate 14, the drain hole 12
and 15 match, and it is possible to drain water and also to drain water immediately without storing water.

Further, in order to conveniently slide the shielding plate 14, it is convenient to provide a knob.

The soft material 1 is constructed higher than the drain plug 9, and its height is determined according to the amount of water stored, and the soft material 1 can be replaced freely.

Therefore, the soft material 1 acts as a packing and can also store water according to its height, and the amount of water supplied above the height of the soft material 1 overflows the soft material 1 and is passed through the drain hole of the drain valve 2 to the drain pipe 16. leaks into

Note that a perforated plate or the like may be provided in the lower part of the drain plug 9.

In addition, 17 is a handle of a drain valve, 18 is a bathtub, and 19 is a washing area.

In the present invention, the soft material 1 is constructed higher than the drain plug, and the soft material 1 is placed higher than the drain plug.
Since it acts as a seal, a certain amount of water is stored, and when used as a washing area in a bathhouse, there is no danger even if the washing area is used as a play area or water play area for babies or children, and the protruding parts are soft. Since it is made of wood, it is not dangerous even if it hits.

Moreover, when cleaning, the stored water can be drained by opening the drain hole, and the stored water or hot water can be used for cleaning, which is very convenient.
