JP 2007-205013 A

  The main problem to be solved by the present invention is that in this type of hair catcher, the captured hair is naturally collected in the hair catcher so that it can be taken out from the hair catcher or easily removed. .

In order to achieve the above object, according to the present invention, a trap hair catcher is a trap hair catcher installed in a bathroom washroom,
It has a bowl-shaped part provided with a plurality of hot water passage holes, and is installed at the entrance of the trap so that its bottom side is inserted into the trap,
The opening area of one through-hole, the range of 12mm ² ~50mm ^2,
And the ratio of the opening area of all the through-holes which occupies for the area of the internal peripheral surface of a bowl-shaped part shall be the range of 11.5%-7.3%.

  According to such a configuration, a vortex is formed when hot water has flowed into the bowl-shaped portion of the hair catcher without causing clogging of the hair catcher and without hindering rapid drainage of hot water generated at the washing place. Thus, the hair can be taken out from the hair catcher or gathered in the hook-shaped portion so as to be easily removed.

  You may form the surrounding area | region without a through-hole between the upper part of a bowl-shaped part, and a bowl bottom. When it does in this way, even if there is little hot water which flows in in a bowl-shaped part by this surrounding area | region, the said vortex can be formed.

  If the flange part hooked on the inlet part of a trap is provided in the upper part of this hook-shaped part, a hair catcher can be detachably supported by this trap part by this flange part.

  In addition, if a hook is provided on the upper part of the hook-like part to protrude sideways and the protruding end is separated from the trap inlet, the hair catcher can be easily removed from the trap using this knob. By removing the hair catcher and turning the hair catcher upside down, the hair accumulated in the hook-shaped portion can be dropped out, and operations such as disposal of the hair can be performed smoothly.

  Moreover, if this hair catcher is made of copper or a copper alloy, the hair catcher and further the inside of the trap can be kept clean by the action of copper ions.

  According to the hair catcher of the present invention, a vortex is formed in the bowl-shaped portion by the hot water generated in the washing place, and the hair captured by the vortex is taken out from the hair catcher or is easily removed from the hair catcher. The hair is not entangled with the hair catcher, and thus the hair catcher has the feature of facilitating cleaning of the trap.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS.

  Here, FIG. 1 shows a state in which the trap 3 is provided with the hair catcher 1 and the metal ion supply tool 2, respectively, and FIGS. 2 and 3 show such a hair catcher 1, and FIGS. Each such metal ion supply tool 2 is shown.

  The hair catcher 1 according to this embodiment is provided in a trap 3 installed in a bathroom washroom, and is used to remove hair from hot water flowing into the trap 3.

  Specifically, the hair catcher 1 is detachably provided at the entrance 30 of the trap 3 so as to cover the entrance 30, and prevents hair from flowing as far as possible from the entrance 30. It is.

  The hair catcher 1 has a bowl-shaped portion 10 having a plurality of hot water through holes 10a, and is attached to a trap 3 established in a bowl-shaped depression Ya formed on a floor surface Y of a bathroom washroom. A trap 3 provided with an upper portion connected to the hole Yb is installed at the inlet portion 30 so that the bottom side of the trap 3 is inserted into the trap 3. What is indicated by a symbol L in the figure is a decorative lid that covers this bowl-shaped depression Ya leaving a gap Yc into which hot water enters.

In the illustrated example, trap 3 is
(1) A short cylinder having a short cylindrical portion 31a, an outer rod 31b that goes around the upper end of the short cylindrical portion 31a, and an inner rod 31c that goes around the lower end of the short cylindrical portion 31a. A mounting ring 31 configured to allow the bottom end of the cylindrical portion 31a to enter the mounting hole Yb;
(2) The inner cylinder part 32a which opened the upper surface and closed the lower end of the cylinder and made the bottom, and the inner cylinder part surrounding the inner cylinder part 32a so as to form a flow path 32c between the inner cylinder part 32a. An outer wall 32b whose upper end is positioned higher than 32a, a connection part 32d between the flow path 32c and a drain pipe (not shown), and a insertion hole for the short cylindrical part 31a of the mounting ring 31; A trap body 32 having an upper lid 32e for closing the upper end of 32b;
(3) The upper end outer rod 33a is hooked on the inner rod 31c of the short cylindrical portion 31a of the mounting ring 31 so as to be suspended in the inner cylinder portion 32a of the trap body 32, and the lower end is A partition cylinder 33 having both ends of the cylinder positioned above the bottom of the inner cylinder portion 32a of the trap body 32 is provided.

  On the outer peripheral surface of the short cylindrical portion 31a of the mounting ring 31, a male screw portion that engages with a female screw portion (not shown) formed in the insertion hole of the upper lid 32e of the trap body 32 is formed. An annular rubber packing 34 is sandwiched between the outer flange 31b of the body 31 and the upper hole edge of the attachment hole Yb, and an annular rubber is interposed between the upper lid 32e of the trap body 32 and the lower hole edge of the attachment hole Yb. The trap 3 is installed in a washing place by screwing the mounting ring 31 to the trap body 32 using the female screw portion and the male screw portion while sandwiching the packing 34. That is, in the illustrated example, the upper end of the cylinder of the mounting ring 31 functions as the inlet 30 of the trap 3.

  In the illustrated example, hot water flowing from the inlet portion 30 of the trap 3 passes through the partition tube 33 and enters the inner tube portion 32a of the trap body 32, overflows from the upper end of the inner tube portion 32a, and flows into the outer wall 32b. It reaches the drainage pipe through the flow path 32c. Sealed water is always stored in the inner cylinder portion 32a so as to block odor from the drain pipe side.

  In the example shown in the figure, the trap interior tool is configured by the metal ion supply tool 2 having a cylindrical shape that fits in the partition cylinder 33 of the trap 3 configured as described above and the hair catcher 1.

  The metal ion supply tool 2 has both the upper and lower ends of the cylinder open and has an outer casing 20 at the upper end of the cylinder. The outer casing 20 is hooked on the inlet 30 of the trap 3 and is suspended in the trap 3. It is comprised by the material which supplies a metal ion to the said sealing water. Thereby, the inside of the trap 3 is kept clean even if the inside of the trap 3 is not frequently cleaned so as not to cause the sealing water to decay as much as possible. In the example shown in the figure, the metal ion supply tool 2 has an inner and outer surface shape on the upper end side of the cylinder that is similar to the inner shape of the mounting ring 31 and the inner shape of the partition tube 33. The action of ions prevents slimming or the like on these inner surfaces. In particular, in the illustrated example, ribs 33b for removing the partition tube 33 projecting inwardly at the upper end of the partition tube 33 are formed at four locations at intervals in the circumferential direction of the tube shaft, and the metal ion supply A recess 21 for receiving this is formed at the upper end of the cylinder of the tool 2 so that the metal ion supply tool 2 will not be disturbed in the trap 3 by the flow of hot water. Further, the metal ion supply tool 2 is formed with a plurality of through holes 22 so that metal ions can be supplied to the inner surfaces of the mounting ring 31 and the partition tube 33.

  Such trap interior devices, that is, the hair catcher 1 and the metal ion supply device 2 can be made of a material that generates metal ions that prevent the seal water from decaying, for example, a metal such as stainless steel. The trap interior may be configured by plating such a metal on the surface of the synthetic resin, or by synthetic resin mixed with such metal powder. From the viewpoint of effectively preventing the decay of the sealed water in the trap 3, and considering the workability and availability of the material, it is optimal to configure the trap interior using copper or a copper alloy. The

  In this embodiment, the hook-like portion 10 of the hair catcher 1 is composed of a hemispherical portion 10c that gradually decreases its inner diameter gradually toward the bottom of the hair catcher 1 and a connecting ring portion 10d described later. The hair catcher 1 includes an outer flange-shaped flange portion 11 that surrounds the flange 10e of the flange-shaped portion 10, and the inner edge of the flange portion 11 and the edge of the hemispherical portion 10c are connected to the mouth from the flange portion 11 side. They are integrally connected via a connecting ring portion 10d that is gently inclined toward the edge side. The hair catcher 1 is provided in the inlet portion 30 of the trap 3 by hooking the flange portion 11 to the inlet portion 30 of the trap 3. In the illustrated example, the flange portion 11 is placed on the outer collar 31b of the mounting ring 31 via the outer collar 20 of the metal ion supply tool 2, and the collar-shaped part 10 has the bottom of the metal ion supply tool 2. Is supported so as to be positioned below the upper end of the partition tube 33 of the trap 3. Thereby, in this embodiment, the hair catcher 1 can be removably supported on the trap 3 by the flange portion 11. Further, if the hair catcher 1 is made of a material that supplies the metal ions, it is possible to prevent slimming or the like from occurring at the inlet 30 of the trap 3 as much as possible.

  Further, in this embodiment, the knob portion 12 is provided on the upper portion of the bowl-shaped portion 10 so as to protrude laterally and to protrude the protruding end away from the inlet portion 30 of the trap 3.

  In the example shown in the drawing, the flange portion 11 is divided at one location, and the knob lower end 12a is integrally connected to the connection ring portion 10d at the division location within the division location, and the knob upper end is provided. 12b is positioned outside the virtual circular arc along the outer edge of the flange portion 11, and the knob portion 12 having a tongue-like shape is formed so that the knob upper end 12b is positioned above the upper surface of the flange portion 11. Is provided. As a result, in this embodiment, the hair catcher 1 is easily removed from the trap 3 using this knob portion 12, and the hair collected in the hook-like portion 10 can be obtained by inverting the hair catcher 1 as it is. It can be dropped out, and such operations as disposal of the hair can be performed smoothly.

  The hot water through hole 10 a is provided in a penetrating manner in the flange 10 of the hair catcher 1. In the illustrated example, each through hole 10a formed in the hemispherical portion 10c is configured as a circular hole. The through-holes 10a of the hemispherical part 10c are adjacent to each other along a virtual curved line extending in a substantially radial direction centering on the bottom of the hemispherical part 10c (that is, the bottom of the bowl-shaped part 10). The hemispherical portion is formed by providing a plurality of through-hole sets 10b formed with a space between the through-hole assembly 10b and the adjacent through-hole sets 10b in the circumferential direction of the hemispherical portion 10c. A plurality are formed in 10c. The virtual curved line is bent in the same direction as the adjacent virtual curved line in the circumferential direction of the hemispherical portion 10c.

  Further, a through hole 10a having a long hole shape extending toward the center of the hair catcher 1 is formed in the connecting ring portion 10d so as to have a substantially equal interval between adjacent through holes 10a in the circumferential direction. It is provided in the state.

The opening area of such hair catcher first cup-shaped portion one formed 10 through hole 10a has a range of 12mm ² ~50mm ^2. If the lower limit of the opening area is less than 12 mm ² , the hair catcher 1 is likely to be clogged by dust or dust contained in hot water other than hair. On the other hand, if the upper limit of the opening area is more than 50 mm ^2, it is insufficient to remove the inappropriate size to flow into the drain pipe. This also conforms to the requirements of 5.7 of JIS standard A4421-1991.

  When the ratio of the opening area of the through-hole 10a to the area of the inner peripheral surface of the bowl-shaped part 10 is too small, the rapid drainage of the hot water generated at a washing place is inhibited. According to the JIS standard, the drainage performance of the trap 3 is set to 60 L / min or more in the drainage test defined in 8.7 of JIS standard A4421-1991. On the other hand, if the ratio of the opening area of the through-hole 10a to the area of the inner peripheral surface of the hook-shaped portion 10 is too large, the hot water flowing into the hook-shaped portion 10 does not form an appropriate vortex. It becomes difficult to collect in the bowl-shaped part 10 so that it can be easily taken out or dropped out.

  The hair catcher 1 is installed in the trap 3 having the structure shown in FIG. 1 as described above, and the hair is mixed with the amount of hot water generally generated in the washing place, and then washed to the washing place. For each example in which the number of through-holes 10a was changed, it was observed whether the hot and cold water formed a vortex in the bowl-shaped portion 10. The results are shown below. (Water amount of flowing hot water: 12.9 L / min (4.3 L / 20 sec)) In addition, the hair catcher 1 of each example does not change the structure other than the number of through holes 10 a formed in the hemispherical portion 10 c.

(Example 1)
Number of through-holes 10a (round holes with a diameter of 4 mm): 69 Open area of all through-holes 10a: 1,452.29 mm ²
Ratio of the opening area of all the through holes 10a in the area of the inner peripheral surface of the bowl-shaped part 10 (area 12,429.69 mm ^{2 including the} through holes 10a): 11.7%
Existence of vortex: None

(Example 2)
Number of through holes 10a (round holes with a diameter of 4 mm): 67 Open area of all through holes 10a: 1,457.15 mm ²
Ratio of the opening area of all through holes 10a in the area of the inner peripheral surface of the bowl-shaped part 10 (area 12,429.69 mm ^{2 including the} through holes 10a): 11.5%
Presence / absence of vortex: Intermittent vortex is generated.

(Example 3)
Number of through holes 10a (round holes with a diameter of 4 mm): 65 Open area of all through holes 10a: 1,402.01 mm ²
Ratio of the opening area of all the through holes 10a in the area of the inner peripheral surface of the bowl-shaped part 10 (area 12,429.69 mm ^{2 including the} through holes 10a): 11.3%
Presence / absence of vortex: Intermittent vortex is generated.

(Example 4)
Number of through-holes 10a (round holes with a diameter of 4 mm): 63 Open area of all through-holes 10a: 1,376.87 mm ²
Proportion of the opening area of all through holes 10a in the area of the inner peripheral surface of the bowl-shaped part 10 (area 12,429.69 mm ^{2 including the} through holes 10a): 11.1%
Presence / absence of vortex: Intermittent vortex is generated.

(Example 5)
Number of through holes 10a (round holes with a diameter of 4 mm): 61 Open area of all through holes 10a: 1,351.73 mm ²
Ratio of the opening area of all the through holes 10a in the area of the inner peripheral surface of the bowl-shaped part 10 (area 12,429.69 mm ^{2 including the} through holes 10a): 10.9%
Presence or absence of vortex: A vortex is continuously generated.

On the other hand, in order to adapt the drainage performance of the trap 3 to the drainage test of the JIS standard, the number of through holes 10a (round holes with a diameter of 4 mm) is 44 or more under the same conditions as the above examples. The opening area of the holes 10a (the sum of the opening areas of the 44 through holes 10a) must be 906.04 mm ² or more. At this time, the area of the inner peripheral surface of the flange 10 (including the through holes 10a). The ratio of the opening area of all the through holes 10a to the total area 12,429.69 mm ² ) is 7.3%.

  From the above, if the ratio of the opening area of all the through holes 10a to the area of the inner peripheral surface of the collar 10 of the hair catcher 1 is in the range of 11.5% to 7.3%. Without damaging the rapid drainage of hot water generally generated in a washing place, a vortex is formed when hot water flows into the bowl-shaped portion 10 of the hair catcher 1, and the hair is taken out of the hair catcher 1, or It was found that they can be collected in the bowl-shaped portion 10 so as to be easily dropped.

  Separately from the example described above, between the upper part of the bowl-shaped part 10 and the bottom of the bowl, a surrounding area without the through hole 10a, specifically, an area without the through hole 10a continues to surround the bottom of the bowl. If it is formed in the shape of a circular band, the vortex can be formed even if there is little hot water flowing into the bowl-shaped portion 10 by such a circular region.
