Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a swirl type filter provided at a connecting portion between various water tanks and suction and drainage pipes, and particularly to hair and fibers. The present invention relates to a swirl type filter improved so that slender foreign matter can be removed efficiently and easily.

[Conventional technology]

Although various shapes and materials are used for the filters provided at the connection between the water tank and the suction and drain pipes, the filters used for domestic and commercial water tanks (for example, bathtubs) are simple and easy to maintain. Inance is required to be easy.

For this reason, a filter used for a bathtub or the like is generally of a type in which water or hot water is passed to separate foreign matters.

FIG. 2 is a schematic system diagram showing a forced circulation type bath.

The hot water in the bathtub 1 passes through the filter 2, is sucked into the pump 4 via the water absorption pipe 3, is heated by the burner 6 when passing through the heat exchanger 5, is refluxed into the bathtub 1 through the connection fitting 7, and is circulated. To do.

FIG. 3 is a schematic system diagram of a bubble bath.

The hot water in the bathtub 1'passes through the filter 2 ', is sucked into the pump 4 via the water suction pipe 3, and is pressurized, and then the bubble bath nozzle 8 is used.
At this time, air bubbles are mixed and ejected into the bathtub 1'as indicated by an arrow a.

[Problems to be solved by the device]

Like the hot water and water in the bathtub illustrated above, long and thin foreign objects such as hair are suspended in the hot water and water that touch the human body.

If foreign matter of this kind is to be separated and removed by a filter, the capture rate will not be so good even if a fine mesh filter is used. If a filter with a finer mesh is used, the water flow resistance will be greater and the pressure loss will be greater, reducing the pump performance.

In addition, even if a filter with a fine mesh is used, clogging by foreign matter progresses with use and pressure loss increases.

Moreover, when removing the captured foreign matter for cleaning, long and thin foreign matter such as body hair is entangled in the filter, which requires a great deal of labor.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a filter having low water resistance, less clogging, and easy maintenance.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the filter of the present invention is provided with a swirl chamber, and a tangling rod is arranged in the swirl chamber.

In FIG. 1 (B) corresponding to the embodiment of the present invention, 12 is a swirl chamber, and its AA cross section is as shown in FIG. 1 (A).

The swirl chamber 12 has a cylindrical shape as shown in both FIGS. (A) and (B), has a top wall 12a, and has a cap shape without a bottom.

In the present invention, the terms "top" and "bottom" of the swirl chamber are terms for facilitating the understanding of the shape and do not mean the vertical direction thereof.

The cap-shaped swirl chamber 12 is attached to a water absorption chamber 14, and a water absorption pipe 16 is connected to the water absorption chamber 14.

A water absorption hole 13 is provided on the side wall of the cylindrical swirl chamber 12, and surrounding water (including hot water, the same applies hereinafter) flows in along the center line of the water absorption hole as indicated by arrows b and b '.

The water suction hole 13 is arranged eccentrically with respect to the cylindrical swirl chamber 12. In the present invention, the water absorption hole is eccentric means that when the cylindrical swirl chamber 12 is viewed in the direction of its center line as shown in FIG. 1 (A), the center line of the water absorption hole (arrow b,
b)), but does not intersect the center point O of the cylinder.

Further, the present invention provides a tangling bar 17 along the center line of the cylindrical swirl chamber.

[Action]

In the swirl type filter constructed as described above, the hot water flows into the swirl chamber 12 as indicated by the arrow b, and swirls as indicated by the arrows c and c '.

Therefore, slender foreign matter such as body hair and fibers are entangled with each other to form a so-called pill.

Even if it is a slender foreign substance, if it becomes a pill, it will hardly pass through even if the mesh 15 has coarse meshes.

At this time, if there is a rod-shaped member (entangled rod 17) arranged along the center line of the vortex chamber 12, the vortex flows around the entangled rod, and pills are formed around the entangled rod.

When the swirl chamber 12 formed and mounted in the cap shape is removed, the pill-shaped foreign matter can be easily taken out together with the entanglement rod.

〔Example〕

FIG. 1 shows an embodiment of a vortex type filter according to the present invention. The same figure (B) is a longitudinal sectional view, and the AA cross section is the same figure.
Shown in (A).

A water absorption chamber 14 is fixed to penetrate the wall of the bathtub 11, and the water absorption chamber 14 is connected to a suction port of a pump (not shown) via a water absorption pipe 16.

The swirl chamber 12 is formed in a cylindrical shape having a closed bottom, and its bottom opening is detachably attached to the water absorption chamber 14. 12a is the top wall, and in this example, the top wall is installed toward the center of the bathtub.

The side wall (cylindrical wall) of the cylindrical swirl chamber 12 has a pair of suction holes.
13 are provided.

When the present invention is implemented, the number of water absorption holes to be arranged can be set arbitrarily.

The surrounding water flows into the swirl chamber 12 in the direction along the center line of the water suction hole 13 and is swirled as shown by arrows c and c ′ in FIG. It flows into the water absorption pipe 16 as indicated by the arrow d.

A mesh 15 is installed along the boundary between the swirl chamber 12 and the water absorption chamber 14. The net 15 of this example is a flat plate-shaped member having a coarser mesh than the conventional example. Therefore, the water flow resistance of the net alone is smaller than that of the conventional example.

The present invention arranges the entanglement bars along the centerline of the cylindrical swirl chamber.

In the present embodiment, one end of the entanglement rod 17 is screwed to the center of the top wall 12a of the cap-shaped swirl chamber 12, and the entanglement rod 17 penetrates the net 15 and is a bearing provided at the bottom of the water absorption chamber 14. It is fitted to the boss 18.

As shown in this example, one end of the entanglement rod 17 is provided with a cap-shaped vortex chamber
If it is fixed to 12, it is convenient for attaching and detaching the entanglement rod 17.

Further, when the structure in which the other end of the entanglement rod 17 is fitted to the bottom portion of the water absorption chamber 14 as in this example is used, the entanglement rod is securely supported and easily attached and detached.

However, when the present invention is implemented, the entanglement bar functions as an entanglement bar if it is arranged along the center line of the swirl chamber. Therefore, it is not always necessary to penetrate the net 15 or fit the bottom surface of the water absorption chamber 14 as in this example.

When the water flowing into the swirl chamber 12 swirls as shown by the arrows c and c ′, slender foreign matter such as body hair and fiber debris suspended in the water are entangled with each other, forming a pill around the entanglement rod 17. Become. Therefore, even if the mesh 15 has a coarse mesh, it hardly penetrates.

In the conventional example of a bathtub filter, the capture rate of foreign matter is generally
Although it was about 60%, the capture rate of the swirl filter of this example was
It was confirmed by experiment that it was 98%.

Moreover, the removed foreign matter does not become entangled with the net 15 because the entangled rod 17 forms a pill ball, and there is no risk of clogging the net.

Moreover, since the pills are formed around the entanglement rod, if the vortex chamber 12 is removed from the water absorption chamber 14 and the entanglement rod 17 is taken out, the trapped foreign matter can be removed very easily.

As can be easily understood from the above operation, in order for the filter of the present embodiment to achieve the intended purpose, the swirl chamber 12 only needs to have a hollow cylindrical portion inside, and the shape of the outer peripheral surface. It doesn't matter.

In the present invention, the cylindrical vortex flow chamber means a cylindrical vortex flow chamber whose inner peripheral surface is a cylindrical surface, and the outer peripheral surface is not necessarily required to be a cylindrical surface.

The embodiment shown in FIG. 1 is one in which the swirl filter of the present invention is installed at the connecting portion between a bathtub and a water absorption pipe as an example of a water tank, but the scope of application of the present invention is limited to this example. The same action and effect can be obtained by applying the vortex type filter of the present invention to the connection portion between the face-wash tub and the drain pipe of a vanity table as an example of a water tub.

[Effect of device]

As described above, when the vortex type filter of the present invention is applied, since a mesh having coarse mesh can be used, the water flow resistance in the state of being clean and obtained is small, and the clogging accompanying the use is extremely slight. In addition, since the captured foreign matter can be removed quickly and easily, maintenance is easy.
