Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a drain filter. More particularly, the present invention relates to a drain filter for installing in a drain of a washroom, a bathroom or a kitchen sink, etc., which can easily and reliably remove dust such as hair, scale, and lint. The present invention relates to a drain port filter that prevents dirt such as red and cloth waste from flowing out to a drain port and prevents clogging of a drain pipe.

[0002]

2. Description of the Related Art When garbage such as hair, red, and lint is discharged from a drain port to a drain pipe, the drain pipe may be clogged, or hair, red, dust, etc. Dust sticks or accumulates, so that the amount of water required for the trap function cannot be maintained, and the trap function is hindered. Particularly in drain pipes of condominiums, clogging of drain pipes is a major cause of damage to drain pipes. In order to prevent such drainage clogging,
Conventionally, various drainage filters have been proposed.

[0003] For example, Japanese Utility Model Laid-Open No. 59-65707 and Japanese Utility Model Laid-Open No. 55-163371 disclose one end of a cylindrical net, cover the net with a mesh, and remove the mesh covered with the mesh. It is disclosed that it is placed at a drain. Similarly, Japanese Utility Model Application Laid-Open No. 62-83516 discloses a method in which a cut is made in one of two meshes, the two meshes are superimposed on each other, the periphery is thermally bonded, and a perforated plate is inserted from the cut. It has been proposed to place a mesh-covered plate in the drain.

[0004] In these cases, there is a problem that the mesh plate covered with the net is difficult to be inserted into the drain port. Also,
There is a problem that it is extremely difficult to remove the perforated plate when the perforated plate is forcibly inserted into the drain port when the perforated plate is removed. In addition, since the mesh is directly covered with the mesh, hair, red, debris such as lint must adhere to the mesh, and when removing the mesh, the dust must be touched. There is a problem that it is not very hygienic.

[0005] As a method for solving the above-mentioned problem that the perforated plate is difficult to insert, Japanese Utility Model Application Laid-Open No. 63-17330 discloses a method.
In Japanese Patent Application Laid-Open No. 5 (1999) -2005, it is proposed that an adhesive is applied around the outer edge of the filter, and the filter is adhered to the periphery of the drain port or the perforated plate using the adhesive.

[0006] However, when the filter is to be adhered to the periphery of the drain hole or the perforated plate with the adhesive, the use of the drain port or the perforated plate is a place easily wetted by water. Does not work well and the filter cannot be adhesively fixed. For this reason, when flowing water, the filter is moved by the drainage, and the effect of the filter is often not sufficiently exhibited.

On the other hand, the filter can be attached by wiping the application portion of the adhesive with a dry cloth and then applying the adhesive, but this time, when removing the filter, the filter is peeled off against the adhesive. Must be done, and the work is troublesome. In addition, in the filter disclosed in Japanese Utility Model Application Laid-Open No. 63-173305, the removal work is unsanitary because dust such as hair, red, and lint is uniformly adhered to the surface of the filter. It is. Further, in this case, it is necessary to replace the entire filter, which is expensive.

Japanese Utility Model Application Laid-Open No. 63-181410 discloses that a base having a groove on a circumferential surface is covered with a net, and the groove of the base is fitted into a circular hole of an elastic rubber sheet. . Then, the elastic sheet is placed on the drain port, but there is a problem that it is easy to move like the one disclosed in Japanese Utility Model Laid-Open No. 63-173305, and the operation of removing the net from the base is also unsanitary. is there.

On the other hand, in Japanese Patent Application Laid-Open No. 4-106232, a net is sandwiched between two ring members, and the entire filter is fixed to a perforated plate with claws attached to the lower side of the two ring members. Is disclosed. By doing so, the movement of the filter with respect to the perforated plate can be prevented.However, since the net is flat, the surface of the net is uniformly stained. Removing the eye from the eye is equally dirty and unsanitary.

Japanese Patent Application Laid-Open No. 7-300889 discloses that a plastic-molded filter is provided with a protruding piece which can be picked by hand, and the protruding piece is also used as a locking piece for locking the inner wall of the drain pipe. ing. With this filter, there is a locking piece that prevents the filter from moving, but the protruding piece that can be picked up by hand to insert the entire filter into the drain pipe of the drain port becomes dirty, and this protruding piece is held. The task of removing the filter is dirty and unsanitary.

Japanese Patent Application Laid-Open No. Hei 7-300889 discloses that a flat plastic molded filter is provided with a locking piece for engaging with a perforated plate. Since dust such as hair, scale, and lint is attached, it is still unsanitary when removing a dirty filter.

[0012]

SUMMARY OF THE INVENTION The present invention has a problem associated with the above-mentioned prior art, namely, the filter attached to the drain port does not move easily, and the filter effect can be sufficiently exhibited. Even when the filter is dirty, it is possible to perform processing by gripping a not-so-dirty portion, to perform the filter replacement operation in a sanitary manner, and to make the filter member of the filter inexpensive, thereby reducing the cost of using the filter. It is an object of the present invention to provide a drainage filter capable of reducing the amount of water.

[0013]

According to the present invention, there is provided a substrate portion, an arch-shaped connecting member which connects substantially opposing portions of the substrate portion and has a mountain shape, and the substrate portion attached to the arch-shaped connecting member. The above-mentioned object is achieved by a drain filter characterized by comprising an annular member formed of a filter mounting rod-like member projecting beyond the filter and a cylindrical filter member having one end closed.

Further, according to the present invention, an elastic member is provided together with the above-mentioned filter mounting rod-shaped member, one end is attached to the substrate portion, the other end is located near the mounting rod-shaped member, and the other end is bent. An operating member for fixing the filter protruding beyond the substrate may be provided on the annular member. In this case, it is preferable that the filter mounting rod member and the filter fixing operation member are substantially parallel to each other across the diameter of the substrate.

In the present invention, the substantially opposed portions of the annular members are connected by an arch-shaped connecting member having a mountain shape. This arch-shaped connecting member is located above the substrate,
Preferably, the filter is symmetrically bulged, and a filter mounting rod-shaped member is attached substantially at the center of the bulged portion, and the filter member is placed over the arch-shaped connecting member.

When the drain filter of the present invention thus formed is mounted on the drain, the water flowing into the drain enters the drain while swirling, as is often seen. At this time, since the vortex is swirled around the peak of the chevron of the arch-shaped connecting member described above, it is covered near the vertex of the arch-shaped connecting member and the arch-shaped connecting member of the filter member and protrudes near the peak. Since the portion hardly gets wet and is not contaminated, when replacing the filter, the filter can be replaced without soiling the hands by picking the filter member near the vertex of the arch-shaped connecting member.

That is, as described above, by swirling around the arch-shaped connecting member in the shape of a mountain at the time of drainage so as to surround the raised filter member covered thereon, the hair and the red Debris such as cloth waste is securely collected on the arch-shaped connecting member by the filter member wound around the raised filter member in an orderly and efficient manner.

In particular, as shown in an embodiment to be described later, after the closed end of the cylindrical filter member is put on the arch-like connecting member, the other end of the filter member is placed above the vertex of the arch-like connecting member. Is folded over, and then the annular member is wrapped by the other end of the filter member, so that the one end of the filter member is further raised, and the above-mentioned effect is more remarkable. Although not shown in the embodiment, the closed end of the cylindrical filter member is put on the arch-shaped connecting member, and the other end of the filter member is not folded back and the annular member is passed over as it is. The other end of the member may wrap the annular member.

Further, as shown in an embodiment to be described later, when the other end of the filter member is folded inward from the bottom surface of the annular member, the filter member is moved downward from the portion covered by the arch-shaped connecting member and to the lower side of the annular member. This is preferable because it is doubled with the folded portion, so that the filtering effect is further enhanced and fine dust can be collected.

As described above, the filter member that has collected the dirt such as hair, scale, and lint is lifted up and removed by holding the raised portion on the arch-shaped connecting member.
Dust such as hair, scale, and lint can be easily removed and disposed together with the filter member.

A filter mounting rod-like member projecting beyond the substrate is attached to the arch-like connecting member.
The filter can be prevented from moving due to water flow or the like by engaging the filter mounting rod-shaped member with the hole of the perforated plate.

Still more preferably, by providing the above-described filter fixing operation member together with the filter mounting rod member, the plate is sandwiched between the filter mounting rod member and the filter fixing operation member, or the plate is sandwiched by both members. By pressing the gaps between the holes outward, the movement from the eye plate can be more reliably prevented.

It is preferable that the substrate has a diameter larger than that of the drain port, whereby all the waste water flowing into the drain port can be filtered by the filter of the present invention. Also, make the bottom of the board flat, and the bottom of the board is in close contact with the perforated plate or the floor where the drain port is installed. It is preferable to prevent garbage from flowing out.

In order to easily cover the filter member on the arch-shaped connecting member, it is necessary that the end of the above-mentioned filter mounting rod-shaped member on the side of the arch-shaped connecting member protrudes beyond the arch-shaped connecting member toward the opposite side of the substrate. preferable. By inserting one end of the filter member into this protruding portion, the filter member does not move, and in this state, the other end of the filter member is bent around the substrate portion to easily remove the filter member. It can be put on the substrate part.

Another method is to use the filter mounting rod-like member in a dangerous place if the end of the arch-like connecting member on the arch-like connecting member protrudes from the arch-like connecting member, such as a drain port in a bathroom with a flat floor. In such a case, a mounting member having a semicircular cross-section to be fitted to the arch-shaped connecting member is attached to one end of the filter member without projecting the filter mounting rod-shaped member, and the filter member is attached by the mounting member. The filter member may be turned upside down in a fixed state, and the other end of the filter member may be bent to the lower side of the substrate.

Further, in the present invention, the combination of the drainage filter according to the present invention and the drainage fixing support of the drainage filter enables the drainage filter to be securely mounted. In this case, the drainage fixing support has a plate-like support having a hole for fixing the drainage filter in the center, and three or more elasticities extending outward from the support. It is characterized by comprising a leg having.

b).

FIGS. 7 (c) and 7 (d) show the case where the mesh plate 8 is used. In this case, the filter mounting rod 3 and the filter mounting member 3 are placed in two different meshes 8b of the mesh plate 8. By inserting the tip of the operation member 4, the drainage filter is fixed on the eye 8. In some cases, it is also possible to sandwich the net between the members 3 and 4 using a force that is elastically deformed such that the filter fixing operation member 4 is deformed toward the filter mounting rod member 3. is there.

FIGS. 7 (e) and 7 (f) show the aforementioned FIG.
It is very similar to the embodiments (a) and (b), except that the holes 8
This is the case where a is not a circle but a long hole.

FIGS. 7 (g) and 7 (h) show the drainage filter according to the present invention when the center of the perforated plate 8 has no hole and the long holes 8a are provided on both sides of the center. In this method, two long holes 8 are provided adjacent to each other by the tip of the filter mounting rod 3 and the tip of the filter fixing operating member 4.

By fixing the filter on the filter member, the drain filter according to the present invention filters out dirt such as hair, red, waste cloth and the like in the drainage without moving, and filters and collects the dirt on the filter member 5. be able to.

As a method different from the method for fixing the drainage filter to the drainage hole plate as described above, a drainage hole fixing support as shown in FIGS. 12 and 13 is used instead of the drainage hole plate. 12 may be used. The drainage fixing support 12 has a plate-shaped support having a hole for fixing the drainage filter in the center, and three or more elastic legs extending outward from the support. It is characterized by consisting of.

More specifically, as shown in FIG. 12, a drain port insertion portion 3c at the tip of the filter mounting rod-shaped member 3 of the above-described drain port filter is provided at the center of an appropriately shaped plate-like support member 9 such as a circle. A circular hole 9a for inserting the drainage hole insertion portion 4b at the tip of the filter fixing operation member 4 is provided, and the plate-like support 9 can be used in three directions (a direction in which an angle interval of 120 degrees is maintained). Three elastic legs 10 are provided. The length of the leg 10 is cut or formed into a size slightly longer than the diameter of the drainage plate to form the tip 10 a of the leg 10. As shown in FIG. 13, the perforated plate locking portion 1 of the perforated plate main body 13 above the drain pipe 14.
The distal end 10a of the leg 10 is locked to 3a, and the support 9 is fixed.

The material for the drain port fixing support 12 may be any material having elasticity. For example, it may be made of metal such as spring steel or synthetic resin such as polyethylene, polypropylene, or polycarbonate. Thick paperboard may be used. By using the drainage fixing support 12, the drainage filter according to the present invention can be flexibly applied to various drainage openings regardless of the pattern in the present situation where there are various patterns of the plate. You can.

In the drain port fixing support 12 described above, the dimension up to the tip 10a of the leg 10 is slightly longer than the diameter of the drain hole plate. Since the distance between the portions 10a is smaller than the diameter of the drainage plate, it is conceivable that the drainage holes may be accidentally dropped, for example, when there is no trap in the drainage outlet and the drainage pipe is suddenly formed. As a countermeasure against such a thing, FIG.
As shown in FIG. 14, a slim auxiliary leg 11 cut to be equal to or slightly longer than the length of the leg 10 may be arranged between the legs 10 shown in FIG.

As described above, the tip 11a of the auxiliary leg 11
Is slightly longer than the diameter of the drain
It is possible to prevent the drainage fixing support 12 from dropping into the drainage port.

In particular, when the drainage fixing support 12 shown in FIGS. 12 to 14 is used, it is possible to omit the filter operating member from the drainage filter according to the present invention. . That is, as shown in FIG.
By inserting the tip of the filter mounting rod-shaped member of the drainage filter according to the present invention into the hole 9a formed in the plate-like support 9 of the drainage fixing support 12, the drainage filter is almost in a fixed position. Fixed to

As described above, in the present invention, the above-mentioned arch-shaped connecting member 2 has a mountain shape, and the filter member 5 is put on the arch-shaped connecting member 2 having the mountain shape. The member 5 is raised above the chevron-shaped part of the arch-shaped connecting member 2. In particular, as described with reference to the present embodiment, when the filter member 5 placed on the arch-shaped connecting member 2 is turned upside down and turned over to the bottom surface of the annular member 7, the protrusion of the filter member 5 becomes remarkable. In addition, by folding the filter member 5 covering the arch-shaped connecting member 2 inward at the bottom surface of the annular member 7, the filter member 5 is doubled, and the removal of dust such as hair, red, and debris during drainage is performed. The effect is enhanced.

The water flowing into the drain is drained while swirling around the top of the arch-shaped connecting member 2 and the raised portion of the filter member 5 placed thereon. Therefore, the apex portion of the arch-shaped connecting member 2 and the raised portion of the filter member 5 placed thereon are hardly wet. And, as mentioned above, by swirling,
The hair is efficiently and sufficiently collected so as to wind neatly around the top of the arch-shaped connecting member 2 and the raised portion of the filter member 5 placed thereon, and at the same time as the hair, dirt such as red, cloth waste, etc. Is well collected.

In general, a drainage unit is provided at a drainage port of a bathroom or the like (a recess formed on a floor surface of a bathroom or the like with a perforated plate on the bottom surface).
In the case of using, since a large amount of wastewater temporarily flows into the drainage unit at the time of drainage, when the drainage filter according to the present invention is installed in the drainage plate using such a drainage unit, the wastewater flows in. A large amount of drainage causes a stronger vortex to be swirled, and the effect of collecting dust such as hair, scale, and lint is enhanced.

When the filter member 5 is contaminated to some extent, the vertex portion of the arch-shaped connecting member 2 is picked up with a finger through the filter member 5 placed on the arch-shaped connecting member 2, By pinching the vertex portion of the connection member 2 and the lever portion 4a of the filter fixing operation member 4 with a finger, the drainage filter according to the present invention can be easily detached from the perforated plate 8, and the filter can be easily removed. The raised portion of the member 5 is pulled to remove the filter member 5 from the filter mounting insertion portion 3a of the filter mounting rod member 3 and discard it.

Another embodiment is shown in FIG. 8 and FIG. In this embodiment, as shown in FIG. 9, the tip of the filter mounting rod 3 is prevented from protruding above the arch-shaped connecting member 2. In this state, in order to securely fix the filter member 5 to the arch-shaped connecting member 2 of the annular member 7, one end of the filter member 5 has a fixing mounting member 5d having a semicircular cross section, as shown in FIG. I'm wearing In the embodiment shown in FIGS. 8 and 9, the mounting member 5 d of the filter member 5 is used.
Is fitted to the arch-shaped connecting member 2. For the other parts of this embodiment, the same parts as those of the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted. The operation method of the embodiment shown in FIGS. 8 and 9 is the same as that of the embodiment described above.

FIGS. 10 and 11 show still another embodiment of the present invention. In this embodiment, a rod-shaped member 6 as shown in FIG. 10 is used as a filter mounting member, and the rod-shaped member 6 is inserted into a filter mounting insertion portion 6a having an acute angle as shown in FIG. The end 5b of the filter mounting opening of the filter member 5 is inserted, and the filter free portion 5c of the filter member 5 is folded back toward the picking end 6b.
Is bent outward to produce a mushroom-shaped member as shown in FIG. 11, and this is placed on a support rod 11 installed in a small-diameter drain port 10 such as a drain port of a wash basin. To prevent the outflow of dust such as hair, scale, and lint from the drain port 10 such as a wash basin. In particular, the embodiment shown in FIGS. 10 and 11 can reliably prevent the contact lens from erroneously flowing out by being used when the contact lens is washed with the sink.

[0056]

According to the present invention, it is possible not only to prevent the drainage filter from moving due to drainage, but also to apply it to more drainage outlets without being influenced by various patterns of the perforated plate. It is possible to reliably collect garbage such as hair, red, waste cloth, etc. while draining, and when collecting garbage and replacing the dirty drain filter,
By having the peak portion of the chevron-shaped arch-shaped connecting member via the filter member, the drain filter can be removed hygienically with almost no soiling of hands. In addition, in the present invention, the hair is swirled with the drainage water stream so that the hair is wound around the raised portion of the arch-shaped connecting member and the filter member placed thereon, so that dust such as hair, red, and debris is removed. It is collected efficiently and efficiently and sufficiently. By removing the filter member with the drainage filter of the present invention removed from the drainage port, the dirty filter member can be easily removed and replaced with a new filter member. Further, the filter member is extremely inexpensive, and the cost when using the drainage filter of the present invention can be extremely reduced.
