Description

  The aspect of this invention is related with the hair catcher installed in the drain outlet of the washroom of a bathroom.

  In general, for example, a drain trap installed in a bathroom washroom forms a sealed water by the trap body and a sealing cylinder, and prevents odors and pests on the downstream side of the drain trap from flowing into the room. Yes. A mesh-like hair catcher is detachably attached to an opening through which water flows into the drain trap in order to collect garbage such as hair. In this way, the hair catcher attached to the opening can suppress the inflow of garbage such as hair into the drain trap.

  However, hair or the like collected by the hair catcher may be pushed out of the mesh by the flow of water and caught on the mesh. Moreover, hair, dirt, etc. accumulate in the mesh and may stick to the hair pushed out from the adjacent mesh. Then, there is a problem that it takes a lot of trouble to remove the hair collected by the hair catcher. In addition, there is a problem that the mesh is clogged with hair or dirt and the drainage capacity is lowered.

  On the other hand, there is a hair catcher that includes a bottom surface having an opening and a peripheral wall standing upward from the bottom surface, and the peripheral wall has a wall region and an opening region from below in the vertical direction (patent) Reference 1). In addition, a bottom mesh portion in which a large number of holes are formed in the circumferential direction at the bottom of the mortar shape, a non-mesh portion where no hole is formed above the bottom mesh portion, and above the non-mesh portion, There is a hair catcher provided with an intermediate mesh portion formed by drilling a large number of holes in the circumferential direction (Patent Document 2). Moreover, there is a hair catcher provided with a water retention part having a drain hole, an upper drainage outflow part, and a drainage introduction part that allows the drainage to flow in a vortex (Patent Document 3).

However, in the hair catcher described in Patent Document 1, since the hair is biased to the corner portion between the bottom surface and the peripheral wall, the hair may not fall off simply by removing the hair catcher and turning it over. There was room for improvement in care.
Further, in the hair catcher described in Patent Document 2, since the hair accumulates so as to overlap the bottom mesh, the bottom mesh may be clogged, and it is necessary to perform daily care so that the hair does not accumulate. .
In addition, in the hair catcher described in Patent Document 3, since water flows along the side surface by the drainage introduction part, hair easily accumulates on the side surface, and the hair that floats in the temporary water retention part gathers at the bottom, and is thus fixed. There is a possibility that the drainage hole may be clogged with hair, and it was necessary to perform daily care so that the hair does not collect.

  The present invention has been made on the basis of recognition of such a problem, and an object thereof is to provide a hair catcher that can collect hair so that the drain hole is not easily clogged and is easy to care for. To do.

The invention of claim 1 is a hair catcher installed at a drain outlet provided in a bathroom washroom, wherein a drain hole is formed on the bottom surface, and a bowl portion capable of retaining water, and an upper portion of the bowl portion. And an overflow outflow portion for allowing water overflowing from the bowl portion to flow into a drain pipe, and a flange portion formed at an upper portion of the overflow outflow portion, wherein the bowl portion has a thickness of 13 mm to 27 mm. The bowl portion has a substantially hemispherical shape having a depth, and the hair collected in the bowl portion and accumulated in a circle is repeatedly rotated in the vertical direction on the hair by the water flowing into the bowl portion from the washing area. It is made to be gathered into a spherical shape .
Here, the “substantially hemispherical shape” is not limited to a shape obtained by dividing a complete sphere into two parts, but includes shapes shown in the embodiments described later.
According to this, as hair etc. accumulate in a hair catcher, hair etc. grow so that it may gather up in a three-dimensional spherical shape. Therefore, hair or the like is not laminated on the bottom surface of the hair catcher as in the conventional case. Therefore, the hair or the like is not easily entangled with the hair catcher, and the hair or the like can be easily removed.
“Spherical” refers to a rounded three-dimensional shape such as a true sphere, an elliptical sphere, or an eyebrows shape.
Moreover, since hair etc. are not laminated | stacked planarly on the bottom part of a hair catcher, the drainage hole is not obstruct | occluded with the hair laminated | stacked planarly, etc., and the drainage of a hair catcher becomes favorable. . Therefore, water hardly collects in the bowl portion, drying of hair and the like is promoted, and hair and the like can be easily taken out from the hair catcher.
Therefore, even if the frequency of cleaning the hair catcher is lowered, it is possible to easily clean the hair catcher.

In the invention of claim 2 , the inner surface from the overflow outflow portion to the bowl portion is smoothly connected.
According to this, since the water flowing into the bowl part can be vigorously flowed along the bowl part, the hair or the like is more easily collected.

FIG. 1 is a schematic cross-sectional view showing a drain trap provided with a hair catcher according to an embodiment of the present invention.
FIG. 2 is a schematic perspective view showing the hair catcher according to the present embodiment.

  The hair catcher 200 according to the present embodiment is provided at a drain outlet 510 installed in a bathroom washing place 500.

  The drainage outlet 510 includes a drainage inclined surface 121 that guides water flowing from the washing place 500 to the hair catcher 200.

  As shown in FIG. 1, the hair catcher 200 according to the present embodiment is provided in the drain trap 100. The drain trap 100 includes a drain trap body 110 and a sealing cylinder 120, and can form a sealed water W. Accordingly, the drain trap 100 prevents odors, pests, and the like on the downstream side of the drain trap 100 from flowing into the bathroom.

  The hair catcher 200 is detachably attached to the sealing tube 120 of the drain trap 100 and collects garbage such as hair and dirt (hereinafter referred to as “hair etc.” for convenience of explanation) flowing in from the bathroom washroom. Can do. The hair catcher 200 includes a bowl part 210, an overflow outflow part 220, and a flange part 230.

  The bowl part 210 has a mortar shape, and the inflowing water can be retained. That is, the bowl part 210 can store the water flowing from the bathroom washroom. As shown in FIG. 1, the side surface of the bowl part 210 has a substantially spherical shape inclined with respect to the horizontal plane, and the inclination angle of the lower side surface of the bowl part 210 with respect to the horizontal plane is the horizontal plane of the upper side surface of the bowl part 210. It is smaller than the inclination angle with respect to. In other words, the inclination angle of the side surface of the bowl part 210 with respect to the horizontal plane gradually decreases from the upper part to the lower part of the bowl part 210. Moreover, the depth of the bowl part 210 is 18 mm.

  In addition, as illustrated in FIG. 2, the bowl portion 210 has a drain hole 213 formed in the bottom surface portion 211. The drain hole 213 has a circular through hole that penetrates the bottom surface portion 211. The bottom surface portion 211 is provided with a plurality of drain holes 213. The drain hole 213 is provided so as to draw a circle with the center of the bottom surface portion 211 as an axis. The circle has a diameter of about 20 mm in this embodiment.

  The overflow outflow part 220 extends upward from the upper part of the bowl part 210 and causes the water overflowing from the bowl part 210 to flow out to the drain pipe 310 (see FIG. 1). In the present specification, “water” includes not only cold water but also heated hot water.

  As shown in FIG. 1, the side surface of the overflow outflow portion 220 is inclined with respect to the horizontal plane. The inclination angle of the side surface of the overflow outflow portion 220 with respect to the horizontal plane is, for example, about 15 to 90 °. The inclination angle of the lower side surface of the overflow outflow portion 220 with respect to the horizontal plane is larger than the inclination angle of the upper side surface of the overflow outflow portion 220 with respect to the horizontal plane. In other words, the inclination angle of the side surface of the overflow outflow portion 220 with respect to the horizontal plane gradually increases from the top to the bottom of the overflow outflow portion 220.

  The flange portion 230 is formed at the upper portion of the overflow outflow portion 220 and can be engaged with the opening edge portion 122 of the sealing cylinder 120 of the drain trap 100.

As shown in FIG. 2, the overflow outflow portion 220 includes vertical ribs 221 and horizontal ribs 223. The vertical rib 221 connects the bowl part 210 and the flange part 230. Moreover, the overflow outflow part 220 is provided with a plurality of vertical ribs 221. The horizontal rib 223 connects the plurality of vertical ribs 221 in the horizontal direction. The plurality of vertical ribs 221 are provided apart from each other. Further, when a plurality of horizontal ribs 223 are provided, the plurality of horizontal ribs 223 are provided apart from each other. Therefore, as shown in FIG. 2, the overflow outflow portion 220 has a lattice-shaped opening 225. The opening area of the opening 225 is wider than the opening area of the drain hole 213.
In addition, the form of the overflow outflow part 220 is not limited to the form which combined the vertical rib 221 and the horizontal rib 223. FIG.

FIG. 3 is a schematic cross-sectional view for explaining the state of hair and the like collected by the hair catcher according to the present embodiment.
FIG. 4 is a schematic cross-sectional view for explaining the state of hair and the like on the inner surface of the bowl portion.
FIG. 3A is a schematic cross-sectional view illustrating a state of hair or the like when water is flowing in. FIG.3 (b) is typical sectional drawing explaining the state of hair etc. when the inflow of water decreases.

  As shown in FIG. 3A, the hair catcher 200 according to the present embodiment can collect hair 350 and the like flowing in from a bathroom washroom. Here, when the amount of water discharged from the drain hole 213 is smaller than the amount of water flowing in as indicated by an arrow A1 shown in FIG. Then, as shown in FIG. 3A, the collected hair 350 or the like can float on the water accumulated in the bowl portion 210 while the amount is small.

  In addition, since the opening area of the drain hole 213 is smaller than the opening area of the opening 225, water tends to accumulate in the bowl part 210. On the other hand, since the opening area of the opening 225 is larger than the opening area of the drain hole 213, the water overflowing from the bowl part 210 as shown by the arrows A7 and A8 shown in FIG. Can be overflowed more reliably. Thereby, it can suppress that water overflows into a washing place. According to this, it can suppress that hair etc. 350 are caught in the drain hole 213, or entangled. Moreover, since it can suppress that the hair etc. 350 adheres in the drain hole 213, it can suppress that the drain hole 213 is obstruct | occluded by the hair 350.

  Further, as described above with reference to FIGS. 1 and 2, the side surface of the overflow outflow portion 220 is inclined with respect to the horizontal plane. Therefore, as shown by arrows A3 and A4 shown in FIG. 1 and arrows A5 and A6 shown in FIG. Therefore, the hair 350 can be prevented from being entangled with the overflow outflow portion 220. In addition, it is possible to prevent dirt such as soap dust from adhering to or sticking to the overflow outflow portion 220. Thereby, it is possible to prevent the hair from being captured by the dirt adhering to the overflow outflow portion 220 and to overflow the water overflowing from the bowl portion 210 more reliably from the opening 225. Therefore, it can suppress more reliably that water overflows into a washing place.

  In addition, as illustrated in FIG. 2, the inner surface of the vertical rib 221 (the surface on the side where the inflowing water flows) is located above or inside the inner surface of the lateral rib 223 (the surface on the side where the inflowing water flows). . In other words, the horizontal rib 223 is provided so as to recede from the vertical rib 221. Therefore, it is possible to suppress the inflow of water from being obstructed by the lateral rib 223. Accordingly, it is possible to prevent the hair 350 from being entangled with the overflow outflow portion 220 or the hair 350 from flowing out from the opening 225 of the overflow outflow portion 220.

  As described above with reference to FIGS. 1 and 2, the inclination angle of the lower side surface of the overflow outflow portion 220 with respect to the horizontal plane is larger than the inclination angle of the upper side surface of the overflow outflow portion 220 with respect to the horizontal plane. Therefore, as shown by arrows A3 and A4 shown in FIG. 1 and arrows A5 and A6 shown in FIG. 3, the inflowing water is inclined to the surface of the sealing cylinder 120 of the drain trap 100 and the overflow outflow portion 220. Flowing along. Therefore, it is possible to suppress the hair 350 or the like 350 accumulated in the bowl part 210 from returning to the overflow outflow part 220 due to the momentum of the water flow. According to this, it can suppress that hair etc. 350 are caught in the opening part 225 of the overflow outflow part 220, or entangled. Moreover, it is possible to prevent the hair 350 from flowing out from the opening 225 of the overflow outflow portion 220.

  As shown in FIGS. 1 and 2, the lower portion of the overflow outflow portion 220 is smoothly connected to the bowl portion 210. Therefore, the water flowing from the washing place 500 flows vigorously along the inner surface of the bowl portion 210 from the inner surface of the overflow outflow portion 220. The hair 350 or the like is collected in the bowl portion 210 by the flow of water flowing in with this momentum. That is, the hair is gathered in the bowl part 210 and is combined with dirt. Furthermore, as described above with reference to FIGS. 1 and 2, the bowl portion 210 has a mortar shape that is substantially hemispherical. As shown in FIG. 2, the plurality of drain holes 213 are arranged in a circle on the bottom surface portion 211 and are not formed in the central portion of the bottom surface portion 211. The inclination angle of the lower side surface of the bowl part 210 with respect to the horizontal plane is smaller than the inclination angle of the upper side surface of the bowl part 210 with respect to the horizontal plane. Therefore, hair etc. 350 are likely to gather in the bowl part 210. Further, the hair 350 or the like can be floated on the water accumulated in the bowl portion 210 to make a unit. Thereby, it can further suppress that hair etc. 350 are caught in the lattice-shaped opening part 225 of the overflow outflow part 220, or are entangled. Moreover, it is possible to prevent the hair 350 from flowing out from the opening 225 of the overflow outflow portion 220.

  Subsequently, when the amount of water flowing in becomes smaller than the amount of water discharged from the drain hole 213, the water accumulated in the bowl portion 210 is water as indicated by an arrow A11 shown in FIG. It is discharged from the hole 213. Then, as shown in FIG. 3B, the collected hair and the like 350 is in a state of riding on the bowl part 210. At this time, as long as the amount of the hair 350 is small, the hair 350 is gathered in a circle along the drain holes 213 arranged in a circle on the bottom surface portion 211 of the bowl portion 210. In this embodiment, it is gathered into a ring shape having a diameter of about 20 mm.

  Here, as shown in FIG. 4B, when the ribs are not provided on the inner surface of the bowl part 210 and the unevenness is not formed, the contact area between the inner surface of the bowl part 210 and the hair 350 or the like is Wider. Therefore, the united hair 350 or the like easily adheres to the inner surface of the bowl part 210. Then, even if the hair catcher 200 removed from the drain trap 100 is inverted, the collected hair 350 or the like may not be easily removed.

  On the other hand, as shown in FIG. 1 and FIG. 2, the vertical rib 221 of the overflow outflow portion 220 of the present embodiment extends to the inner surface of the bowl portion 210 and forms irregularities on the inner surface of the bowl portion 210. ing. Therefore, as shown in FIG. 4A, the hair or the like 350 is in a state of riding on the vertical ribs 221 that extend to the inner surface of the bowl part 210. According to this, the contact area between the inner surface of the bowl part 210 and the hair 350 can be suppressed, and the hair 350 can be prevented from sticking to the hair catcher 200.

Next, the case where the hair etc. 350 has accumulated will be described.
The behavior of the hair 350 or the like 350 gathered in a ring shape in the bowl portion 210 is changed by receiving the flow of water in the bowl portion 210 as the amount increases.
At first, the hair 350 or the like gathered in a ring shape shows a behavior of rotating in a plane even when subjected to the movement of water, and remains in the ring shape. However, as the amount of hair etc. 350 increases, the hair etc. 350 comes to be gathered into a circle in which hair is also present in the ring. The hair 350 or the like gathered in a circular shape shows the behavior of rotating in the vertical direction in the bowl portion 210 in response to the flow of water. And while repeating this vertical rotation, the circular hairs 350 etc. come to be gathered into a three-dimensional spherical shape. In addition, the rotation in the vertical direction is not limited to the rotation in the vertical plane, but includes that in which the rotation direction is inclined obliquely.
The three-dimensional spherical hair 350 or the like has a smaller contact area with the hair catcher 200 than in the case of a flat circular shape. Therefore, it is possible to easily remove the hair 350 from the hair catcher 200.

Table 1 shows the result of observing the unity state of the hair 350 and the like by changing the depth of the bowl part 210.
As shown in Table 1, when the depth of the bowl part 210 is 16 mm and 22 mm, the hair 350 is rotated in the vertical direction in the bowl part 210 and the hair 350 is gathered into a three-dimensional spherical shape. . Therefore, the hair 350 or the like could be taken out from the hair catcher 200 very easily.
On the other hand, if the depth of the bowl part 210 is as shallow as 12 mm, the hair 350 and the like are not collected in a spherical shape but are collected in a circular shape. Therefore, compared with a spherical thing, the ease of taking out the hair etc. 350 from the hair catcher 200 falls. This is presumably because the hair 350 or the like 350 having a ring shape or a circle shape with a diameter of about 20 mm is difficult to rotate in the vertical direction in the shallow bowl portion 210. That is, the reason why the hair 350 is gathered into a spherical shape is that the depth of the bowl portion 210 depends on the diameter when the plurality of drain holes 213 are arranged in a circle on the bottom surface portion 211 (about 20 mm in this embodiment). it is conceivable that. Or it is thought that it depends on the diameter (about 20 mm in this embodiment) of the hair 350 etc. gathered in the ring shape or circle shape in the bowl part 210. FIG.
Moreover, even if the depth of the bowl part 210 is as deep as 28 mm, the hairs 350 are not collected in a spherical shape but are collected in a circular shape. Therefore, compared with a spherical thing, the ease of taking out the hair etc. 350 from the hair catcher 200 falls. This is presumably because the flow of water flowing from the top of the hair catcher 200 does not flow vigorously to the bottom of the bowl portion 210, and the hair 350 or the like gathered in a ring shape or a circle is difficult to rotate in the vertical direction.

  FIG. 5 is a schematic cross-sectional view illustrating a state in which the hair catcher and the sealing tube of the present embodiment are engaged.

  In a state where the hair catcher 200 according to the present embodiment is attached to the water seal cylinder 120 of the drain trap 100, the flange portion 230 of the hair catcher 200 and the drain trap 100, like the region B1 and the region B2 illustrated in FIG. The sealing cylinder 120 is engaged. Therefore, when removing the hair catcher 200 from the drain trap 100, it can be removed by using the handle 240 provided at the upper end of the hair catcher 200 and sliding the hair catcher 200 obliquely upward.

  Here, as illustrated in FIG. 5, when a large amount of hair 350 or the like spreads and accumulates in a planar shape, the drain hole 213 may be blocked by the hair 350 or the like. Then, when removing hair etc. 350, the water may have accumulated in the bowl part 210. In this case, since the hair 350 is not dried and remains wet, the wet hair 350 can be removed from the hair catcher 200 even if the hair catcher 200 is removed from the drain trap 100 and turned upside down or turned over. The collected hair etc. 350 cannot be easily removed.

  On the other hand, according to the present embodiment, when hair or the like 350 accumulates, it changes from a ring-shaped unit to a circular unit through a circular unit. For this reason, the hair 350 or the like does not collect in a flat shape. Therefore, it is difficult for water to remain in the bowl part 210, and the hair 350 is dried in a spherical shape. Therefore, the hair 350 or the like can be easily removed simply by inverting the hair catcher 200 or turning it over.

  FIG. 6 is a schematic perspective view illustrating the flow of water in the handle portion of the present embodiment.

The handle 240 of this embodiment is provided at the upper end of the hair catcher 200. In addition, the upper surface 245 of the handle 240 is formed so as to be substantially along the upper surface 121 of the sealing tube 120. Therefore, it is possible to prevent the flow of water flowing through the upper surface 245 of the handle 240 from being obstructed by the handle 240 as indicated by an arrow A12 illustrated in FIG. Moreover, the width D1 of the handle 240 with respect to the flow of water flowing through the upper surface 245 of the handle 240 is relatively long. Therefore, it is possible to prevent the hair 350 or the like from being caught on or entangled with the handle 240.
As shown in FIG. 1, the lower surface 247 of the handle 240 has a form along the inclined drainage surface 121 of the drainage port 510. Therefore, the hair 350 or the like is not easily entangled between the inclined drainage surface 121 and the lower surface 247 of the handle 240. Thereby, the hair catcher 200 becomes easier to care for.

  FIG. 7 is a diagram illustrating an example of a result of an experiment performed by the inventor.

The diagram shown in FIG. 7 shows how the hair 350 is collected by the hair catcher 200 every day. In this experiment, a family of three bathed and washed their hair every day.
On the first day and the second day, in the initial stage, it can be observed that the hairs 350 are gathered in a ring shape. After that, when the use is continued, the shape of the ring is changed from the ring shape to the circular shape around the 6th day, and further, the hair 350 etc. starts to be collected into a spherical shape around the 10th day. It can be observed that
Since the three-dimensional spherical hair 350 does not block the drain hole 213 of the bowl 210, it is difficult for water to remain in the bowl 210, and drying of the hair 350 is promoted. If the hair 350 or the like is dried, the hair catcher 200 is not entangled and does not stick. Therefore, the collected hair 350 and the like could be easily discarded simply by removing the hair catcher from the drain outlet and inverting it.

As described above, the hair catcher 200 according to the present embodiment gathers in a ring shape while the amount of hair etc. 350 is small, but as the hair etc. 350 collects, the hair etc. 350 grows into a three-dimensional spherical shape. To do. Therefore, the hair 350 or the like is not laminated on the bottom surface portion 211 of the hair catcher 200 in the conventional manner. Therefore, the hair 350 is not easily entangled with the hair catcher 200, and the hair 350 can be easily removed.
Moreover, since the hair etc. 350 is not laminated | stacked planarly on the bottom face part 211 of the hair catcher 200, the drain hole 213 is not obstruct | occluded with the hair etc. 350 laminated | stacked planarly, and the hair catcher 200 is covered. The drainage is good. Therefore, water hardly accumulates in the bowl portion 210, drying of the hair 350 is promoted, and the hair 350 can be easily taken out from the hair catcher 200.
Therefore, even if the frequency of cleaning the hair catcher 200 is lowered, it is possible to easily perform the cleaning.

  The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions. As long as the features of the present invention are provided, those skilled in the art appropriately modified the design of the above-described embodiments are also included in the scope of the present invention.
