Description

[Detailed description of the invention] [Industrial application field] This invention relates to a drainage device.

[Conventional technology and its problems]

It has been common practice to place a garbage container on the sink of a sink, put kitchen waste in the garbage container, drain the water, and then transfer it to another garbage bag. If you do, the garbage container will become dirty or have water scale, making it necessary to clean it.

Therefore, garbage is often placed in a garbage container such as a nylon bag and placed in the garbage bag.In this case, the drained water collects at the bottom of the garbage bag, making it difficult to dispose of the garbage. , the water in the garbage bag needs to be drained. Because of the drainage,
When the garbage bag is tilted, the garbage inside spills out, and water adheres to the garbage, making it impossible to remove the water completely and making draining extremely time-consuming.

Note that if you use a garbage bag with a drainage hole, the drained water will naturally flow out through the drainage hole, so the above-mentioned inconvenience will not occur. This causes the inconvenience that the garbage container gets dirty, and when the garbage bag is disposed of, drops fall onto the floor and stain the surrounding area.

[Purpose of the invention]

In view of the above points, it is an object of the present invention to provide a drainage device that can automatically drain water accumulated at the bottom of a garbage bag without getting the hands dirty.

[Structure of the invention]

In order to achieve the above object, the present invention forms a valve hole in the bottom plate of a water supply cylinder having an opening for water supply in the upper part, and incorporates a float valve for opening and closing the valve hole into the inside of the water supply cylinder. The upper parts of the bottom plate of the water bottle communicate with each other, and the communication part connects the upper part of the suction cylinder and the discharge cylinder, which communicate with the inside of the water cylinder through the valve hole, and the lower end of the suction cylinder is connected to the lower end of the discharge cylinder. The structure is such that the suction cylinder and the discharge cylinder are arranged higher up and can be adjusted to expand and contract.

[Effect]

For example, to drain water that accumulates at the bottom of a garbage bag using the drainage device configured as described above, the lower end of the suction tube is positioned within the water stored in the garbage bag, and the discharge tube is positioned outside the garbage bag. After filling the water cylinder with water and floating the float valve from the valve hole to drain water from the suction and discharge cylinders, the float valve descends as the water level drops and closes the valve hole.
The siphon action drains the water stored in the garbage bag.

〔Example〕

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

As shown in FIGS. 1 and 2, the bottom plate of the water supply cylinder 1, which is open at the top, has a double bottom, and a valve hole 3 is formed in the center of the upper bottom plate 2.

Further, inside the water supply cylinder 1, a float valve 4 for opening and closing the valve hole is incorporated. This float valve 4 has a flat valve plate 6 attached to the lower outer periphery of a hollow spherical float 5, and when the valve plate 6 overlaps the upper bottom plate 2, the valve hole 3 is closed.

The lower bottom plate 7 of the water supply cylinder 1 is connected to the upper parts of a suction cylinder 9 and a discharge cylinder 10 that communicate with a chamber 8 formed between the lower bottom plate 7 and the upper bottom plate 2, and the lower end of the suction cylinder 9 is connected to the lower bottom plate 7 of the water supply cylinder 1. is located above the lower end of the discharge cylinder 10. In addition, a filter case 1 is provided at the lower end of the suction cylinder 9 to prevent dirt from entering inside.
1 is installed.

The drainage device shown in the example consists of the above structure,
Using this drainage device, for example, as shown in FIG. 9 is located in the water stored inside the garbage bag 21 and the discharge tube 10 is positioned outside the garbage container 20.
Make sure to add the specified amount of water.

Now, when the water supply cylinder 1 is filled with water and the float valve 4 is floated from the valve hole 3, water flows from the chamber 8 to the suction cylinder 9 and the discharge cylinder 10, and flows out from the lower end of each cylinder. Due to the outflow, the water level in the water supply cylinder 1 decreases, and when the float valve 4 descends and closes the valve hole 3, the chamber 8, suction cylinder 9, and discharge cylinder 10 are filled with water. At this time, the valve hole 3 is closed by the float valve 4 to prevent air from entering, and since the lower end of the suction cylinder 9 is located higher than the lower end of the discharge cylinder 10, there is a gap between the discharge cylinder 10 and the suction cylinder 9. A pressure difference occurs at Therefore, the water inside the discharge tube 10 flows out from the lower end,
Due to the outflow, water inside the suction tube 9 is sucked, and a siphon effect occurs between the discharge tube 10 and the suction tube 9. As a result, the water stored in the garbage bag 21 flows from the suction cylinder 9 to the chamber 8 and the discharge cylinder 10, as shown by the arrow in FIG. 2, and flows out from the lower end of the discharge cylinder 10. Therefore, the water inside the garbage bag 21 is drained to the outside up to the lower end of the suction cylinder 9.

As in the embodiment, the suction cylinder 9 and the discharge cylinder 10
By combining a plurality of pipes with different diameters to be expandable and retractable, the water stored in the garbage bag placed inside the garbage container can be drained even from a garbage container of any height.

In the embodiment shown in FIG.
Although the valve plate 6 is shown in FIG. 4, the upper bottom plate 2 is formed of an elastic material such as rubber, as shown in FIG.
If the upper surface is inclined downward toward the valve hole 3, the spherical float valve 4 will move toward the valve hole 3 and close the valve hole 3 as the water level decreases. The plate 6 can be omitted.

FIG. 5 shows another embodiment of the drainage device according to the present invention. As shown in the figure, a valve hole 3 is formed in the bottom plate 2 of the water supply cylinder 1, and a float valve 4 for opening and closing the valve hole 3 is provided with an umbrella-shaped valve plate 6.
comes into contact with the upper surface of the bottom plate 2, whereby the valve hole 3 is completely closed.

Further, the suction cylinder 9 and the discharge cylinder 10 connected to the bottom plate 2 communicate with each other at the upper part, and the communication part 12
is connected to the inside of the water supply cylinder 1 through the valve hole 3, similar to the chamber 8 shown in FIG.
With such a configuration, the water supply tube 1, the suction tube 9, and the discharge tube 10 can be formed by molding, so the drainage device can be easily formed.

In the embodiment, the case where water inside a garbage bag is drained has been described as an example, but the usage example of the drainage device is not limited to this.

〔effect〕

As described above, in the drainage device according to the present invention, when the water contained in the water supply cylinder is drained from the valve hole, the float valve descends and closes the valve hole, allowing outside air to flow into the suction cylinder and the discharge cylinder. To prevent intrusion, automatic siphoning can be performed between the suction cylinder and the discharge cylinder.

Therefore, by simply putting a predetermined amount of water into the water supply cylinder, the water in the garbage bag can be automatically drained without getting your hands dirty.

In addition, by making the suction tube and the discharge tube freely adjustable, water can be reliably drained even if the depth of the garbage bag is different.
