Description

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

[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. In order to drain the garbage, 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 very 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.

(Object of the Invention) In view of the above-mentioned 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 arranges a float valve for opening and closing the valve hole inside the water supply cylinder, The upper parts of the bottom plate of the water cylinder communicate with each other, and the communication part connects the upper parts 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 upper part of the discharge cylinder. The structure is such that it is positioned above the lower end.

[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. In the process, water is poured into the water supply cylinder, the float valve is floated from the valve hole, and water is drained from the suction and discharge cylinders.As the water level drops, the float valve descends and closes the valve hole, and then the garbage bag is removed by the siphon action. It drains stored water.

〔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 in communication with a chamber 8 formed between the lower bottom plate 7 and the upper bottom plate 2. The lower end is located above the lower end of the discharge cylinder 10. Further, a filter case 1) is attached to the lower end of the suction tube 9 to prevent dirt from entering inside.

The drainage device shown in the embodiment has the above-mentioned structure. For example, as shown in FIG. Place the water supply cylinder 1 on the periphery of the container 20, and insert the suction cylinder 9.
is located in the storage water inside the garbage bag 21, and the discharge tube 1
A predetermined amount of water is put into the water supply cylinder 1 while the container 0 is placed outside the garbage container 20.

When the water supply cylinder 1 is filled with water and the float valve 4 is floated from the valve hole 3, the 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 7L3 is closed by the float valve 4 to prevent air from entering, and since the lower end of the suction cylinder 9 is located above the lower end of the discharge cylinder 10, there is no space between the discharge cylinder 10 and the suction cylinder 9. A pressure difference occurs. Therefore, the water inside the discharge cylinder 10 flows out from the lower end, and the water inside the suction cylinder 9 is sucked by the outflow, and a siphon effect occurs between the discharge cylinder 10 and the suction cylinder S. As a result, the water stored in the garbage bag 21 flows from the suction tube 9 to the chamber 8 and the discharge tube 10, as shown by the arrow in FIG.
flows out from the bottom end. Therefore, the water inside the garbage bag 21 is drained to the outside up to the lower end of the suction tube S.

As in the embodiment, when the suction cylinder S and the discharge cylinder 10 are formed to be expandable and contractible by combining a plurality of pipes with different diameters,
Even for a garbage container of any height, the water stored in the garbage bag placed inside the garbage container can be drained.

In the embodiment shown in FIG.
However, as shown in Fig. 3, if the upper bottom plate 2 is made of an elastic material such as rubber and its upper surface is sloped downward toward the valve hole 3, a spherical shape can be obtained. Since the float valve 4 moves toward the valve hole 3 and closes the valve hole 3 as the water level decreases, the valve plate 6 can be omitted.

Does Figure 5 relate to this invention? 1. As shown in FIG. 0, which shows another embodiment of the water supply device, 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 has an umbrella-shaped valve. A plate 6 is provided, and when the valve plate 6 comes into contact with the upper surface of the bottom plate 2, the valve hole 3 is completely closed.

Further, the suction cylinder S 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, making it easy to form the drainage device.

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, since the present invention has the above-described structure, it is easy to place the lower end of the suction cylinder in the water storage, expose the discharge cylinder to the outside of the water storage, and fill the water supply cylinder with a predetermined amount of water. This action allows water to be removed automatically from now on without getting your hands dirty.
