Description

  The present invention relates to a hair catcher that is attached to a drain outlet such as a bathroom or a washstand and collects hair or the like.

A conventional hair catcher is detachably attached to a drain outlet such as a bathroom or a washstand. In addition, the hair catcher has a discharge hole for discharging the inflowing wastewater to the downstream pipe in a collection part for collecting hair and the like.
The above-described hair catcher is known to have a handle portion for easy removal, and the handle portion has a handle portion in which the grip portion extends in the horizontal direction and a grip portion at the top. A handle portion extending toward the front is known.

Among the handle portions, the handle portion extended in the horizontal direction has a large size in the horizontal direction because the handle portion jumps out to the outside of the hair catcher. (Patent Document 1)
In addition, since the handle portion is attached and detached by grasping the upper surface and the lower surface (back surface), a certain space is required below the handle portion so that a hand can be inserted. Therefore, since the said handle part is extended in the horizontal direction after raising to a position somewhat higher than the attachment surface of the hair catcher, the hair catcher has become larger in the vertical direction.
That is, the hair catcher having the handle portion extending in the horizontal direction requires a wide space in the horizontal direction and the top-and-bottom direction in the vicinity of the attachment portion (drainage port), so that the installation environment is limited. It was.

On the other hand, in the handle portion extended upward, the handle portion does not have to jump out of the hair catcher. (Patent Document 2)
That is, when the handle portion is extended upward, the size can be reduced in the horizontal direction as compared with the hair catcher having the handle portion extended in the horizontal direction.
However, since the handle portion extended upward is gripped on its side, it is slippery when unlocking the hair catcher or removing the collected hair, and the workability is poor. In particular, when soap, detergent, or the like is attached to the handle portion, it is remarkably easy to slip. In addition, Patent Document 2 describes a structure in which an opening large enough to allow a finger to enter the handle portion. In this case, the height of the hair catcher in the vertical direction is increased.

  Hereinafter, the hair catcher of this invention is demonstrated, referring drawings. The following description is for facilitating understanding of the embodiment, and the present invention is not limited and understood by this. In the following embodiments, the upper, lower, left and right directions will be described with reference to the mounting state shown in FIG.

  As shown in FIG. 1, the hair catcher 1 which concerns on 1st embodiment is attached to the drain 10 of the washing-room pan P described below, and collects hair etc.

  The washing place pan P is a waterproof pan on the washing place side provided with a shower, a faucet and the like in the bathroom, and is provided with a drain port 10 for draining the waste water to the downstream pipe. The drain port 10 is a part of the washing area pan P that has been depressed one step, and is provided at the lowest position of the washing area pan P. A drain trap 11 is attached to the drain area 10.

  The drain trap 11 includes a drain trap body 12, a flange member 13, and a deodorizing cylinder 14, and the flange member 13 and the drain trap body 12 are screwed to the drain port 10 via a packing 15. The flange member 13 is provided with a deodorizing cylinder 14 and a later-described hair catcher 1, and a blindfold plate 20 is placed on the hair catcher 1.

  The drain trap body 12 has a drain branch pipe 18 into which drainage from a bathtub (not shown) flows, and an outlet 17 connected to a drain pipe on the downstream side. The drain trap body 12 has a collar 16 inside, and drains in the collar 16. Can be temporarily stored to form a sealed water.

  The deodorizing cylinder 14 has an upper end that can be fixed to the flange member 13 and is composed of an inclined portion that is inclined from above to the middle and a cylindrical portion that is suspended from the lower end of the inclined portion. In the state where the deodorizing cylinder 14 is attached to the flange member 13, the lower end of the deodorizing cylinder 14 is disposed below the upper end of the flange 16 and above the lower end of the flange 16.

  When the drainage from the washing place pan P flows into the drainage trap 11 composed of the above-described members, the drainage is stored in the flange 16. At this time, since the flow path formed by the inside of the deodorizing cylinder 14 and the flow path formed by the outside of the deodorizing cylinder 14 and the inside of the flange portion 16 are filled with the drainage, air or water from the downstream side (sewage side) It becomes impossible for pests and the like to enter the bathroom. That is, the sealed water is formed by the drainage from the washing place pan P.

  In addition, also when drainage from a bathtub arises, ie, when drainage flows in from the drainage branch pipe 18, drainage is similarly stored in the collar part 16 and sealed water is formed.

  As shown in FIGS. 2 to 6, the hair catcher 1 attached to the drain port 10 (drain trap 11) has an inflow path 2, a collection part 3, an outflow hole 4, a raised part 5, an overflow hole 6, and a lock groove. 7 and non-slip 9. Moreover, the hair catcher 1 which concerns on 1st embodiment is the two-fold symmetrical shape of planar view circle shape, Comprising: The cross-sectional view is formed in the substantially mortar shape.

The collection part 3 has a circular shape in plan view, and is formed by the concave part of the center of the hair catcher 1, and a plurality of outflow holes 4 are formed in the bottom part. The outflow hole 4 collects the waste water that has flowed into the collection unit 3 without flowing through the hair in the waste water. In addition, collection here is not necessarily limited to collecting all the hair in waste_water | drain. Further, annular ribs are provided concentrically on the bottom surface of the collection unit 3 with the collection unit 3 as a center to prevent hair and the like from sticking to the bottom surface of the collection unit 3.
Note that the outflow hole 4 is formed only around the central portion (bottom) of the collection portion 3, and no outflow hole 4 is provided from the middle to the upper end of the collection portion 3.

  The inflow path 2 is formed in two locations around the collection portion 3 in a spiral shape in plan view. Further, the inflow path 2 is formed from the outer edge of the hair catcher 1 toward the collection unit 3, and guides waste water from the washing place pan P to the collection unit 3. The inflow channel 2 joins the collecting unit 3 along the tangent line of the collecting unit 3 and is formed so that the flow path width becomes narrower as the collecting unit 3 is approached. Here, when the hair catcher 1 is attached, the lower end of the end portion of the inflow passage 2 (outer edge of the hair catcher 1) is disposed at substantially the same height as the upper end of the flange member 13.

The raised portion 5 is formed by raising (extending) a part of the hair catcher 1 upward. At the position from the outer edge of the hair catcher 1 to the upper end of the collecting portion 3, the inflow path 2 is formed. Are provided in two circumferential directions. In addition, as shown in FIG. 4, on the upper surface of one bulging portion 5, "open" and "closed" are shown along with arrows indicating the rotation direction so that the rotation direction when the hair catcher 1 described later is attached and detached becomes clear. The letters are engraved.
The raised portion 5 is provided with an overflow hole 6 only on its upper surface, and no hole is provided on its side surface. Therefore, the raised portion 5 has a role as a guide wall that regulates the inflow direction of the wastewater flowing in from the inflow passage 2 by the side surface. Note that the upper surface of the raised portion 5 is formed substantially horizontally.
Further, the raised portion 5 is provided with a non-slip 9. The non-slip 9 is a plurality of projections and depressions juxtaposed by projecting convex portions outward from the outer surface of the hair catcher 1, and is formed in the circumferential direction at the outer edge of the hair catcher 1. Further, as shown in FIGS. 5 and 6, the anti-slip 9 is provided in two rows in the vertical direction on the outer surface of the raised portion 5.
Here, as shown in FIG. 7, when the hair catcher 1 is attached and detached, the raised portion 5 (non-slip 9) is gripped, so that the raised portion 5 also serves as the handle portion 8 in the first embodiment. Have.

  The overflow hole 6 is a group of holes formed larger in diameter than the outflow hole 4, and as shown in FIG. 1, when the hair catcher 1 is attached, the overflow hole 6 is disposed at a position higher than the upper end of the flange member 13. Is done. That is, the overflow hole 6 is disposed at a position higher than the mounting surface.

  The lock groove 7 is a groove provided on the outer surface of the hair catcher 1 and is formed to be slightly wider than the protrusion provided on the flange member 13.

  When the hair catcher 1 is attached and detached, as shown in FIG. 7, the outer surface of the handle portion 8 (the raised portion 5) is gripped so as to cover the hair catcher 1 from above. Then, by rotating the hair catcher 1 with the protrusion of the flange member 13 in contact with the lock groove 7, the lock groove 7 and the flange member 13 are fitted, and the hair catcher 1 is attached to the flange member 13, The attached state can be fixed. Further, when removing, the fitting (fixing) can be released by rotating the hair catcher 1 in the direction opposite to the rotation direction. At this time, since the user applies a force to the outer edge of the hair catcher 1, the user can rotate the hair catcher 1 with a small force.

Further, at the time of attaching and detaching, the handle portion 8 (the raised portion 5) is formed with a non-slip 9 at a portion gripped by the user. Accordingly, the user's hand is securely attached with the anti-slip 9 (unevenness bites into the finger), and the hand does not slip even if a force is applied in the circumferential direction when the hair catcher 1 is attached or detached. That is, the friction of the gripping portion is increased by the plurality of unevenness arranged in parallel in the circumferential direction, and slip prevention can be performed when the hair catcher 1 rotates.
In addition, since the anti-slip 9 is arranged in two rows vertically on the outer surface of the raised portion 5, the hand does not slip even when a force is applied in the vertical direction, such as when lifting the hair catcher 1.

  The flow of drainage to the hair catcher 1 is as follows.

When wastewater mixed with hair or the like is generated on the washing place pan P by using a shower or the like, the wastewater flows on the washing place pan P and flows into the hair catcher 1 (drain port 10) from the inflow path 2. At this time, the waste water flowing into the hair catcher 1 becomes a swirling flow by the inflow path 2 provided in a spiral shape, and flows into the collecting portion 3 while swirling. Moreover, since the flow path width becomes narrow as the inflow path 2 approaches the collection part 3, the inflow speed increases as the inflowing wastewater approaches the collection part 3.
And the wastewater which reached | attained the collection part 3 becomes a stronger swirl | flow by the part in which the outflow hole 4 is not formed in the middle to the upper end of the collection part 3, and the hair etc. which were mixed in the wastewater are collected. Summarize in the middle. At this time, drainage (excluding hair and the like) is gradually discharged from the outflow hole 4 of the collection unit 3 into the drain trap.
The inflow path 2 is sandwiched by the ridges 5 and no holes are formed in the side surfaces of the ridges 5, so that the inflowing wastewater flows only from the inflow paths 2 to prevent the occurrence of turbulence. be able to.

When the inflow of the drainage is finished, hairs and the like remain on the hair catcher 1, but the hairs and the like are gathered at one place at the bottom of the collection unit 3 by the flow of the drainage. At this time, since the annular rib is formed on the bottom surface of the collection unit 3, hair or the like does not adhere to the bottom surface of the collection unit 3.
Therefore, when the hair catcher 1 is inverted, the collected hair and the like can be removed. Since the hair catcher 1 is firmly held by the anti-slip 9, the hand does not slip when the hair catcher 1 is reversed. That is, it is not necessary to change the way of holding the hair catcher 1 when removing hair or the like.

  In addition, regarding the flow of drainage with respect to the hair catcher 1 described above, if the drainage flow rate is large and the drainage flow is so large that it cannot fit in the inflow path 2, or if the outflow hole 4 is blocked by hair or the like and drained from the collection unit 3. When the water overflows (when the water level rises to the upper surface of the raised portion 5), the drainage flows out from the overflow hole 6 provided on the upper surface of the raised portion 5. Accordingly, the drainage does not flow back to the washing area pan P side. In addition, since the overflow hole 6 is formed by the hole group which consists of a some hole, it can prevent that hair etc. are discharged | emitted downstream from the overflow hole 6. FIG. In addition, prevention here is not necessarily limited to preventing that all the hair in waste_water | drain is discharged | emitted downstream.

  According to the present invention, since the inflow path 2 is sandwiched between the raised portions 5, the drainage does not flow in an unintended direction when the drainage flows.

  Moreover, since the flow path width becomes narrower as the inflow path 2 approaches the collection part 3, it becomes possible to increase the speed of the inflowing drainage, and a swirling flow can be effectively generated even with a small amount of drainage.

  In addition, since the handle portion 8 extends upward and has a side portion as a grip portion, the size of the hair catcher 1 with respect to the horizontal direction and the top-to-bottom direction can be suppressed, and an anti-slip function can be achieved. The workability at the time of attachment and detachment is improved by 9.

  Moreover, since the handle part 8 is provided on the outer side of the collecting part of the hair catcher 1 and the anti-slip 9 serving as a gripping part is provided on the outer surface of the handle part 8, the hair catcher 1 can be operated with a small force. Can be attached and detached.

The first embodiment of the present invention is as described above. However, the present invention is not limited to the above structure, and various design changes can be made without departing from the scope of the invention.
For example, in the embodiment described above, the inflow passage 2 and the raised portion 5 are provided at two locations, respectively, but may be provided at three locations (three rotationally symmetric shapes) as in the second embodiment shown in FIG. It may be one place or four places or more. Naturally, the hair catcher 1 may not be rotationally symmetric.

Further, the height of the raised portion 5 may be appropriately increased as long as it does not interfere with the blindfold plate 20 provided in the hair catcher 1, and the drainage through the inflow path 2 does not inhibit the swirling flow. If the height is within the range and the slip stopper 9 can be formed, the height of the raised portion 5 may be appropriately reduced. Furthermore, in the case where a plurality of raised portions 5 are formed, the height difference may be formed in each raised portion 5. For example, among the three raised portions 5 according to the second embodiment, only one raised portion 5 may be formed higher / lower. Thereby, the amount of drainage discharged from the overflow hole 6 can be controlled with respect to the amount of drainage.
In the present invention, when the hair catcher 1 is attached and detached, the side surface of the handle portion 8 is gripped, and the anti-slip 9 is provided in the grip portion, so that the height of the raised portion 5 (the handle portion 8) is lowered. Can be gripped without any problem.
Further, the upper surface of the raised portion 5 may be gently inclined toward the collecting portion 3 so that no water droplets remain on the upper surface of the raised portion 5. In this case, after drainage is discharged from the overflow hole 6, the water droplets remaining on the upper surface of the raised portion 5 are guided to the collecting portion 3. Further, hair or the like that has been prevented from flowing out to the downstream side by the overflow hole 6 is also guided to the collecting portion 3 by the inclination of the upper surface of the raised portion 5. Therefore, the top surface of the raised portion 5 is clean without any water drops or hair remaining. In addition, regarding inclination, you may incline toward directions other than the collection part 3. FIG.

  Further, the anti-slip 9 is formed by the protrusion protruding from the side surface of the handle portion 8, but as shown in the second embodiment, the side surface (upper surface) of the handle portion 8 is recessed to form irregularities. May be.

In the first embodiment, the raised portion 5 also serves as the handle portion 8, but the handle portion 8 has a plate-like shape, such as a plate shape, and can be gripped on its side surface. If it is, it may be various shapes. Accordingly, as in the third embodiment shown in FIG. 9, the guide wall 22 also serves as the handle portion 8 by providing the plate-like guide wall 22 with the non-slip 9 for allowing the drainage to flow into the collection portion 3. May be.
In the said 3rd embodiment, you may hold | grip so that the hair catcher 1 may be covered similarly to 1st embodiment, and you may hold | grip so that the inner surface and outer surface of the handle part 8 (guide wall 22) may be pinched. good. Furthermore, a slip stopper 9 may be provided on the inner surface of the guide wall 22 as necessary.
As an example of the gripping method at this time, there is a method in which the slip stopper 9 is gripped from both the inner surface and the outer surface of one guide wall 22.

  Further, the anti-slip 9 can be appropriately changed, for example, by providing a small opening having an appropriate shape / size as in the fourth embodiment shown in FIG. Accordingly, the user's hand is securely attached with the anti-slip 9 (the opening bites into the finger), and the hand does not slip even if a force is applied in the circumferential direction when the hair catcher 1 is attached or detached. That is, the friction of the gripping portion is increased by the plurality of openings arranged in parallel in the circumferential direction, and slip prevention can be performed when the hair catcher 1 rotates.

  Further, if it has a function as an anti-slip, the gripping portion may be subjected to a graining process. Furthermore, as in the fifth embodiment shown in FIG. 11, the gripping portion of the hair catcher 1 has a high friction such as rubber. It is good also as the anti-slip 9 by arrange | positioning the material which has a coefficient. Naturally, a material having a high friction coefficient such as rubber may be provided with unevenness. In addition, since the hair catcher 1 which concerns on the said 5th embodiment is the same as that of 1st embodiment regarding structures other than the slip stopper 9, the description is abbreviate | omitted.

  In each of the above embodiments, the raised portion 5 and the guide wall 22 also serve as the handle portion 8 and have a structure that generates eddy currents. However, even if only the function as the handle portion 8 is provided. good.

  Moreover, the collection part 3 does not necessarily need to be formed in the center of the hair catcher 1, and may change a position suitably, such as an eccentric position.

  Moreover, you may use the hair catcher of this invention for various drain outlets, such as the drain outlet of a washbasin besides the drain outlet of a bathroom.

  Further, the hair catcher of the present invention may have a structure that does not have a locking mechanism by simply inserting and removing in the vertical direction, or simply placing it at the drain outlet, in addition to rotation locking as in the above embodiment. good. In any case, by providing the non-slip 9, it can be easily taken out from the drain outlet.

  Further, the hair catcher of the present invention may be gripped so as to cover the side surface of the hair catcher, in addition to gripping the hair catcher so as to cover the upper side with a hand.
