Description

  The present invention relates to a hair catcher provided in a drain trap.

  The bathroom drain trap is detachably provided with a hair catcher that collects foreign matters such as dust, mainly hair, from the drain. In addition, eddy currents generated outside the hair catcher are introduced into the hair catcher to collect foreign substances.

Patent Document 1 describes a drain outlet provided with a water direction guide portion on the outside of a deep hair catcher so as to generate a swirling water flow in a deep hair catcher installed in a funnel-type sealed water tube. FIG. 13A is a side view showing a drain outlet described in the same document as a cross-sectional view of the funnel-type sealing cylinder 902 and the water direction guide portion 903, and FIG. 13B shows the water direction guide portion 913. It is a side view which shows the hair catcher 911 integrated.
The drain outlet of FIG. 6A is provided with a drainage amount adjusting component 904 attached to the sealing cylinder 902 to reduce the hole diameter of the sealing cylinder 902 so that the swirling water flow rotated clockwise by the water direction guide portion 903 is contained in the sealing cylinder 902. That is, it is generated outside the hair catcher 901. Thereby, it is supposed that a swirling water flow is generated in the hair catcher 901. In the drainage outlet, the wastewater from the washing place flows into the entire hair catcher 901, and the whole wastewater flows down little by little through the drainage amount adjusting component 904.
Moreover, the drain outlet of the same figure (b) forms the water direction guide part 913 in the outer surface of the hair catcher 911 so that it can form integrally or detachably. The drain outlet also generates a swirling water flow rotated clockwise by the water direction guide portion 913 outside the hair catcher 911 and introduces the swirling water flow into the hair catcher 911.
When discarding the hair or the like collected by the hair catchers 901, 911, the entire hair catchers 901, 911 are taken out from the sealing tube 902 and turned over.

Patent Document 2 describes a drainage structure in which bathtub drainage is discharged from a spout provided on an elevation surface of a drainage basin. FIG.13 (c) is a perspective view which shows the drainage structure described in the literature. In this drainage structure, the hair catcher 925 is attached horizontally to the inlet 924 of the bottom surface 923 a of the drainage basin 923, and the discharge direction of the bathtub drainage from the water outlet 921 does not face the center of the inlet 924. For this reason, the bathtub drainage discharged from the water discharge port 921 draws a vortex toward the inflow port 924 and passes through the hair catcher 925.
When discarding the hair or the like collected by the hair catcher 925, the entire flat hair catcher 925 is taken out from the inlet 924 and turned over.

Patent Document 3 describes a drain trap provided in a kitchen sink. FIG. 13D is a vertical sectional view showing the drain trap 930 described in the document. The drain trap 930 is disposed in the trap body 931 having the water catching portion 931a, the sealed water catching portion 931b, and the outer peripheral flow passage portion 931c, the deodorizing cylinder 932 inserted in the sealed water catching portion 931b, and the water catching portion 931a. And a lid 934 that covers the upper surface opening of the water catcher 931a. The outer peripheral flow path portion 931c, the deodorizing cylinder 932, and the lid body 934 are provided with drainage guide means for guiding drainage so that a vortex that rotates in one direction in the sealed water bottle portion 931b is generated by the water flow. The drainage flowing from the sink to the drain trap 930 is guided by the lid 934 so as to generate a vortex in the sealed water trough 931b and passes through the mesh basket 933.
When throwing away the foreign matter collected by the net cage 933, the entire net cage 933 is taken out from the water receiving portion 931a and turned over.

The drainage port shown in FIG. 13 (a) has a limited drainage capacity because all the drainage from the washing area passes through the drainage adjustment component 904. For this reason, the drain outlet may not be sufficiently discharged when a large amount of drainage occurs at one time, such as when hot water overflows from the bathtub. The same applies when the hair catcher 911 shown in FIG.
Further, since the hair catchers 901 and 911 shown in FIGS. 5A and 5B are provided with water direction guide portions 903 and 913 on the outer side, a sealed water tube is required to generate a spiral water flow in the sealed water tube 902. The shape of 902 must be matched to the shape of the water direction guides 903 and 913. Furthermore, since all the waste water from the washing area flows into the entire hair catchers 901 and 911, the hair or the like adheres to the entire hair catcher, and it is difficult to remove the hair or the like from the hair catcher, or the hair catcher may be clogged. is there.
Furthermore, in order to throw away hair and the like, it is necessary to take out the entire hair catchers 901 and 911 from the sealing tube 902 and turn them over.

The drainage structure shown in FIG. 13C requires bathtub drainage in order to generate eddy currents, and needs to form a water discharge port 921 for discharging bathtub drainage in the drainage 923. In addition, since the hair catcher 925 is horizontally disposed and the drainage is not retained on the hair catcher 925 and is quickly passed through the entire hair catcher 925, the hair or the like is easily entangled with the entire hair catcher. For this reason, it may be difficult to remove hair or the like from the hair catcher, or the hair catcher may be clogged.
Furthermore, in order to discard hair or the like, it is necessary to take out the entire flat hair catcher 925 from the inlet 924 and turn it over.

Since the drain trap 930 shown in FIG. 13D is provided not in the bathroom but in the kitchen, a net basket 933 is used instead of a hair catcher. In addition, since the drainage is not retained in the mesh basket 933 and quickly passes through the entire mesh basket 933, if hair or the like is shed, the hair or the like is easily entangled with the entire mesh basket. For this reason, it may be difficult to remove hair from the mesh basket, or the mesh basket may be clogged.
Furthermore, in order to throw away the foreign matter, it is necessary to take out the entire mesh basket 933 from the water receiving portion 931a and turn it over.

  The present invention has been made in view of the above problems, and it is not necessary to provide a special structure for a drain trap provided with a hair catcher, and it is possible to easily remove and discard the collected hair and the like, and a stable drain capacity. The object is to provide a hair catcher capable of obtaining

In order to achieve the above object, the present invention is a hair catcher provided in a drain trap, comprising a hair catcher body and a hair removing member that is detachably attached to the hair catcher body, wherein the hair catcher body In the state where the hair removing member is attached to the lower portion, the lower portion has a lower drainage outflow portion for flowing out the wastewater while suppressing the outflow of the hair in the wastewater, A concave temporary water retention portion that flows out from the drainage outflow portion, and an upper drainage outflow portion that extends from the upper portion of the temporary water retention portion and flows out wastewater that does not enter the temporary water retention portion while suppressing the outflow of hair during drainage. , at least configured and the drainage inlet portion for guiding the waste water from washing place the the temporary water retention portion, at least the one o'clock water retention portion及by the hair catcher body The upper drainage outlet portion is configured, the hair removing member, the one o'clock removably attached to the inner surface of the water retaining unit, the operation of detaching from the temporary water retention portion allows removal of the hair remaining in the one o'clock water holding section It is characterized by being.

That is, the waste water from the washing place is led to the concave temporary water retaining portion by the waste water introducing portion, and flows out from the lower drainage outflow portion while being temporarily retained by the temporary water retaining portion. At this time, the outflow of the hair in the waste water is suppressed. Moreover, the waste water which cannot enter the temporary water retention part flows out from the upper drainage outflow part extended from the upper part of the temporary water retention part. Here, the waste water that does not completely enter the temporary water retention portion does not simply overflow from the upper drainage outflow portion, but flows out from the upper drainage outflow portion while suppressing the outflow of hair.
In the drainage water temporarily stored in the temporary water retention section, hairs etc. float and gather. When the drainage drains from the temporary water retention part, the hair etc. remain in the temporary water retention part in a state where it gathers. Therefore, it is possible to obtain performance that can easily remove the collected hair, that is, good hair removability. Moreover, the hair etc. which remain | survived in the temporary water retention part can be removed by operation which removes a hair removal member from a hair catcher main body. That is, since it is not necessary to take out the entire hair catcher from the drain trap in order to discard the collected hair and the like, it is easy to discard the hair and the like.
Furthermore, since the waste water from the washing place is guided to the temporary water retention unit, the upper drainage outflow portion is prevented from being blocked. Therefore, a stable drainage capacity can be obtained.
In addition, the above-described good hair removability and stable drainage ability can be obtained only by the structure of the hair catcher alone.

The upper Symbol hair catcher, also include those foreign matter other than the hair also collected. In addition to the hair catcher used for the bathroom drain trap, the hair catcher includes a hair catcher used for a bathroom trap drainage trap, a hair catcher used for a barber shop or beauty salon drain trap, and the like. .
The drainage is water containing hair. Therefore, a lower drainage outflow part and an upper drainage outflow part mean a part from which water containing hair flows out.
The lower drainage outflow portion and the upper drainage outflow portion that suppress the outflow of hair during drainage do not have to stop all the hair. That is, deterrence is not limited to stopping everything.
The temporary retention of the drainage by the temporary water retention unit means that the drainage is temporarily accumulated while drainage flows out in the temporary retention unit. Therefore, the residence time of the wastewater in the temporary water retention unit is a finite time. The state of the drainage that exists in the temporary water retention unit while the hair is floating therein is included in the state in which the water is temporarily retained in the temporary water retention unit.
The concave temporary water retaining portion may have any shape that receives drainage and temporarily retains water, and the shape of the temporary water retaining portion includes a bowl shape, a hemispherical shape, an upside down conical shape, an upside down pyramid shape, and the like. Shape is included. Moreover, the concave temporary water retention part is also included in the shape of the temporary water retention part in which the bottom part of these shapes protrudes or bulges upward.

The drainage introduction unit may guide drainage from the washing area to the temporary water retention unit so that a swirling flow rotating in one direction is generated in the temporary water retention unit. Then, since hair etc. are gathered in a temporary water retention part by the swirling flow of drainage, hair removability improves.
The swirling flow refers to a flow in which the drainage existing in the temporary water retention unit rotates, and there is no limitation on the number of rotations until the drainage that has flowed into the temporary water retention unit flows out from the lower drainage outflow unit. Further, the direction of the virtual rotation axis of the swirl flow may be the vertical direction, the horizontal direction, or a direction that is obliquely deviated from the vertical direction or the horizontal direction.

In the bathroom, a washing place W1 provided with a shower, a hot water tap, etc. (not shown) is provided outside the bathtub B1, and a part of the floor material 110 of the washing place W1 is recessed to form a drainage tub 112. This drainage basin 112 has a flange 113 extending inward in a substantially horizontal direction toward the lower opening, and the cover 120 can be attached to and detached from the upper opening. The drainage trap 1 is attached to the drainage basin 112 and allows the drainage that has flowed into the drainage basin 112 from the gap CL1 between the cover 120 and the flooring 110 to pass therethrough. The drain trap 1 includes a cover 120, a trap body 130, a tightening flange 140, a water seal 150, and a hair catcher 2.
At the four corners of the drainage basin 112, as shown in FIG. 2, washing-stage steps 114a and 114a and bathtub-side steps 114b and 114b for mounting the hair catcher 2 and the cover 120 are formed. On the bathtub-side edge 120a of the cover 120, a handle portion 122 that is recessed toward the washing area is formed.

  As shown in FIG. 1, the trap body 130 has an upper opening, a connection port 131 that protrudes horizontally in the lower part of the side wall 130 a on the bathtub side, and a horizontal direction on the side wall 130 b that faces the connection port 131. A protruding discharge port 132 is formed. The connection port 131 is connected to the waterproof pan of the bathtub through a connection pipe. In the trap body 130, a sealing surface S is formed at the upper edge of the side walls 130 a and 130 b, and the lower portion of the sealing cylinder 150 is inserted below the sealing surface S. Further, a flange portion 133 extending radially inward is formed on the upper edge portion of the trap body 130, and a screw portion 133 a is formed on the inner peripheral surface of the flange portion 133.

  The tightening flange 140 includes a cylindrical portion 141 having a threaded portion 141a screwed to the threaded portion 133a of the trap body on the outer peripheral surface, an upper flange portion 142 extending radially outward at an upper edge portion of the cylindrical portion 141, It is formed in a substantially annular shape including a lower flange portion 143 extending radially inward at the lower edge portion of the cylindrical portion 141. On the inner peripheral surface of the cylindrical portion 141, two upper and lower projections 141b are formed at four positions at intervals of 90 °. When the packing 144 is attached to the front end of the flange portion 113 of the floor material, and the fastening flange 140 is screwed into the flange portion 133 so that the packing 144 is sandwiched between the flange portion 133 of the trap body, the flange portion 113 of the floor material and the trap The main body 130 can be fixed to each other.

  The sealing cylinder 150 is formed into a shape having a cylindrical main body 151 and a flange 152 extending radially outward from the upper edge of the main body 151. In the outer edge portion of the flange portion 152, notches are formed at four locations at intervals of 90 °.

As a result, the sealing tube 150 is fixed at a predetermined position in the trap body 130. Here, a gap is provided between the lower end of the sealing cylinder 150 and the bottom surface of the trap body 130.

  As shown in FIG. 2, the hair catcher 2 includes a hair catcher body 10 and a hair removal member 80 that is detachably attached to the hair catcher body. The hair catcher 2 includes a temporary water retaining portion 20, an upper drainage outflow portion 30, and a drainage introduction portion 40 in a state where the hair removing member 80 is attached to the haircatcher main body 10, and in this state, collects dust such as hair from the drainage. To do. In the present embodiment, each of these parts 20, 30, 40 is constituted by the hair catcher body 10, and the hair removing member 80 is detachably attached to the inner surface 20 a of the temporary water retention part 20.

The temporary water retaining portion 20 is formed in a concave shape that is open at the top and recessed downward. The temporary water retaining portion 20 of the present embodiment has a shape in which the apex and ridgeline of the inverted quadrangular pyramid are rounded in order to increase the volume as much as possible in the drainage basin 112 having stepped portions 114 at the four corners. A plurality of drain holes 23 are formed in the lower portion of the temporary water retaining portion 20 near the apex of the quadrangular pyramid to allow the drainage to flow out substantially downward while preventing the outflow of hair or the like in the drainage. The lower part of the temporary water retaining part 20 provided with these drain holes 23 is a lower drainage outflow part 22 according to the present invention. Since the lower drainage outflow portion 22 for draining the drainage is present in the lower portion of the concave temporary water retaining portion 20, eddy current is easily generated in the wastewater temporarily retained in the temporary water retaining portion 20.
On the other hand, the periphery of the lower drainage outflow portion 22 in the temporary water retention portion 20 is a wall portion 21 without a drain hole, and rises obliquely toward the outside. Therefore, the temporary water retention unit 20 causes the drainage to flow out from the lower drainage outflow unit 22 while temporarily retaining the inflowing wastewater.

  The hair removing member 80 has a main body portion 82 accommodated in the temporary water retention portion 20 and a handle 86 protruding from the upper edge portion 82a of the main body portion.

  As shown in FIG. 4 and the like, the main body portion 82 has a plurality of drain holes 83 provided in the lower portion, and a plurality of openings 84 provided at positions corresponding to the wall portion 21 of the temporary water retention portion, It is formed in a shape that matches the inner surface 20a of the temporary water retention part. Each drain hole 83 is formed in accordance with the position of each drain hole 23 in the temporary water retention part so as not to hinder the outflow of drainage from the drain hole 23 in the temporary water retention part. Since the water draining hole 83 of the hair removing member is also formed to have substantially the same size as the water draining hole 23 of the temporary water retaining portion, the drainage is allowed to flow out while preventing the hair from flowing out. Each opening 84 has an opening area larger than that of the drainage hole 83, but prevents the hair remaining together in the main body portion 82 from passing through.

  As shown in FIG. 1, the handle 86 when the hair removing member 80 is attached to the hair catcher main body 10 projects obliquely upward from the main body 82 within the range surrounded by the standing wall 50 of the drainage introduction portion 40. Has been. The handle 86 protrudes so as to approach the standing wall portion 50, and the tip end portion 86 a is set lower than the upper edge portion of the standing wall portion 50. Therefore, when attaching the cover 120 to the drain 112, the handle 86 does not get in the way. By holding the handle 86 by hand, the hair removing member 80 can be removed from the hair catcher body 10, and the hair remaining in the temporary water retention unit 20 can be removed.

When the hair removing member 80 is attached to the hair catcher body 10, the maximum drainage outflow rate Qd (liter / min) of the lower drainage outflow portion 22 is temporarily retained by the drainage from the washing place W1 to the extent that the hair in the drainage floats. A flow rate that temporarily accumulates in the section 20 is preferable. Here, the maximum drainage outflow rate Qd is the outflow rate of drainage flowing out from the lower drainage outflow unit 22 when the drainage is continuously introduced so that the drainage is accumulated in the temporary water retaining unit 20 up to the upper edge portion 21a. And In addition, if Qd is made smaller than the average water discharge flow rate Qs (liters / minute) of the shower used in the washroom, the wastewater from the washroom is temporarily stored in the temporary water retention unit 20 when the shower is used at the average water discharge flow rate. This is preferable. On the other hand, if Qd is set so that the residence time T of the drainage water temporarily retained in the temporary water retention unit 20 is about several seconds to several tens of seconds (for example, 5 to 15 seconds), the temporary water retention unit 20 promptly uses the washing area. This is preferable because drainage can be removed to remove hair and the like.
In order to increase the drainage outflow rate Qd, the total area of the drain holes 23, 83 is increased by increasing the opening area of the drain holes 23, 83 or increasing the number of the drain holes 23, 83. What is necessary is just to enlarge opening area (area which totaled the opening area of each drain hole). Of course, in order to reduce Qd, the total opening area of the drain holes 23 and 83 may be reduced. In this way, the lower drainage outflow portion 22 can be set to a desired drainage outflow rate.

The upper drainage outflow portion 30 extends from the upper portion (upper edge portion 21a) of the temporary water retention portion 20 so as to rise obliquely outward. The upper drainage outlet 30 is formed with a plurality of holes 32 through which drainage flows out while suppressing the outflow of hair during drainage. Since the upper drainage outflow portion 30 allows the drainage that does not enter the temporary water retaining portion 20 to flow out, the maximum drainage outflow rate Qu (liters / minute) of the upper drainage outflow portion 30 is the maximum drainage outflow rate Qd ( L / min). Here, the maximum drainage outflow rate Qu is the drainage that flows out from the upper drainage outflow part 30 when the drainage is continuously introduced so that the drainage is accumulated to the lowest position of the outer edge part 30a of the upper drainage outflow part 30. The outflow rate of Of course, to increase Qu, the total opening area of the hole 32 may be increased, and to decrease Qu, the total opening area of the hole 32 may be decreased. In this way, the upper drainage outflow portion 30 can have a desired drainage outflow rate.
The upper drainage outflow part 30 of the present embodiment extends outward with a gentler slope than the upper part of the temporary water retention part 20 in order to increase the volume of the drainage basin 112 as much as possible.

The drainage introduction unit 40 guides the drainage from the washing place W1 to the temporary water retention unit 20 instead of the upper drainage outflow unit 30. The drainage introduction part 40 of the present embodiment has a standing wall part 50, an inclined part 60, and a flange part 70, and from the washing place W1 so as to generate a swirling flow that rotates counterclockwise (one direction) within the temporary water retention part 20. The wastewater is directly introduced into the temporary water retention unit 20. Note that the swirling flow in one direction in the temporary water retention unit means that the swirl flow in the temporary water retention unit is only counterclockwise, the swirl flow in the temporary water retention unit is only clockwise, etc. It shall mean that the direction of rotation of the flow is one.
The standing wall portion 50 is provided with an inlet 56 for passing drainage from the washing place W1 on the washing place W1 side, the first split standing wall portion 52 and the second division are arranged outside the upper drainage outflow portion 30 with the bathtub side separated. It is comprised from the standing wall part 54. FIG. Since much of the waste water from the washing place W1 flows into the drainage basin 112 from the washing place W1 side, the inlet 56 on the hair catcher 2 is provided at a position where much of the waste water from the washing place W1 flows. Both the split standing wall portions 52 and 54 extend upward from the outer edge portion 30 a of the upper drainage outflow portion 30 so as to surround the upper drainage outflow portion 30. By having the standing wall portion 50, the waste water from the washing station W1 side including hair and the like does not directly enter the upper drainage outflow portion 30, and clogging of the upper drainage outflow portion 30 due to hair or the like can be suppressed. it can.

The inclined part 60 is projected from the outside of the standing wall part 50 through the inflow port 56 toward the direction along the inner peripheral surface of the temporary water retaining part wall part 21, that is, in the temporary water retaining part 20, onto the virtual horizontal plane HP1. The lower drainage outflow portion 22 is lowered toward the position shifted in the horizontal direction from the center of gravity CE1 of the plan view.
Here, the plan view of the hair catcher 2 projected onto the virtual horizontal plane HP1 corresponds to the plan view of FIG. 4, and the plan view of the lower drainage outflow portion 22 (including the portion corresponding to the drain hole 23) is shown in FIG. This corresponds to a figure surrounded by a two-dot chain line represented by. This plane figure includes a portion corresponding to the drain hole 23. The center of gravity CE1 of the plane figure of the lower drainage outflow portion 22 can be obtained by geometry or simulation, and a plate having a uniform weight per unit area is cut out to the shape of the lower drainage outflow portion 22 without the drain hole 23 and balanced. It can also be determined by performing a test to find the point, that is, the center of mass.
The direction from the center of gravity CE1 of the plan view of the lower drainage outflow portion projected onto the virtual horizontal plane to the position displaced in the horizontal direction means that the hair catcher 2 is moved like the drainage flow direction D13 of the inclined portion 60 shown in FIG. When viewed from above, it means to go in a direction not passing through the center of gravity CE1.
Further, the direction of the drainage flow direction D13 is the direction most inclined in the inclined portion 60, and this direction is the direction in which the inclined portion 60 is lowered. The direction in which the inclined portion 60 of the present embodiment is lowered is the right side from the lower drainage outflow portion 22 when viewed in the direction in which the drainage flows.

  The flange portion 70 extends outward from the outer edge portion 30a of the upper drainage outflow portion, receives the wastewater from the washing place W1 outside the standing wall portion 50, and guides it to the inclined portion 60. The flange portion 70 of the present embodiment includes a first region 72 that is mainly outside the first divided standing wall portion 52, a second region 74 that is mainly outside the second divided standing wall portion 54, and these Can be divided into corners 76 and 77 placed one step up at the boundary between the regions 72 and 74 and placed on the washing-stage steps 114a and 114a. The first region 72 and the second region 74 are separated from the bathtub side, and are both connected to the inflow port 56. The first region 72 is gradually lowered clockwise, and guides the drainage in the rotational direction substantially the same as the rotational direction D1 of the swirling flow in the temporary water retention unit 20. The second region 74 is gradually lowered toward the washing area, and guides the drainage from the bathtub side to the inflow port 56. The corner portions 76 and 77 also have a function of guiding the drainage flowing on the first region 72 clockwise or guiding the drainage flowing on the second region 74 to the inlet 56.

The hair catcher 2 has a region where the standing wall portion 50 is not provided on the bathtub side so that the hand catching portion 122 can be easily placed when removing the cover 120, and the bathtub side edge portion of the upper drainage outflow portion 30. 30b is made into the shape connected to the bathtub side edge part of hair catcher itself. Here, most of the drainage from the washing station W1 flows into the drainage basin 112 from the washing station W1 side, so that the hair catcher 2 is compared with the drainage that flows into the temporary water retaining unit 20 from the flange portion 70 via the inclined portion 60. There is little drainage flowing directly into the upper drainage outlet 30 from the bathtub side edge.
As described above, the drainage introduction part 40 mainly guides the drainage from the washing place W1 to the inclined part 60 by the flange part 70, and the drainage is projected from the outside of the standing wall part 50 to the virtual horizontal plane along the inclined part 60. It guides to the temporary water retention part 20 toward the position shifted | deviated from the gravity center CE1 (henceforth the gravity center CE1 of a lower drainage outflow part) of the plane figure of a lower drainage outflow part.

The hair catcher body 10 and the hair removal member 80 can be made of various materials such as resin materials such as thermoplastic resins, metal materials such as stainless steel, and combinations thereof. Can be used.
The drainage trap 1 provided with the hair catcher 2 has, for example, a packing 144 attached to the front end portion of the floor material flange portion 113, and a tightening flange 140 screwed into the flange portion 133 of the trap body to trap the floor material flange portion 113 and the trap material. The main body 130 is fixed to each other, the sealing tube 150 is attached to the tightening flange 140, the hair catcher main body 10 is placed on the drainage trough 114, the hair removing member 80 is attached to the hair catcher main body 10, and the hair catcher main body 10 It is formed by placing the cover 120 on the corner of the.

Next, the operation and effect of the hair catcher 2 will be described. The hair removing member 80 is attached to the hair catcher body 10.
The wastewater generated at the washing place W1 flows into the drainage basin 112 from the periphery of the cover 120 and flows down mainly onto the hair catcher flange portion 70. Here, the drainage flowing down to the corner 76 on the left side of FIG. 5 flows to the first region 72, and the drainage flowing down to the corner 77 on the right side of FIG. Flow to section 60. The drainage on the first region 72 is guided counterclockwise along the first divided standing wall portion 52 and then flows to the inclined portion 60. The drainage on the second region 74 flows to the inclined portion 60 after being guided along the second divided standing wall portion 54 toward the washing place W1. Here, since the slope of the inclined portion 60 along the wastewater flow direction D13 shown in FIG. 5 is larger than the slope of the regions 72 and 74 along the wastewater flow directions D11 and D12, the wastewater flowing into the sloped portion 60 is The speed is increased toward the temporary water retention unit 20. For this reason, a swirl flow can be generated effectively even with a small amount of drainage. Further, the drainage on the second region 74 is guided from the direction opposite to the rotational direction D1 of the swirling flow in the temporary water retaining portion, but the direction is changed by the inclined portion 60 in a direction in which it is difficult to attenuate the swirling flow.

  The drainage flowing down the inclined portion 60 flows into the concave temporary water retaining portion 20 toward a position shifted in the horizontal direction from the center of gravity CE1 of the lower drainage outflow portion 22, and left while being temporarily retained by the temporary water retaining portion 20. It turns around and flows out from the lower drainage outflow part 22 downward. Since the drainage flows in the direction along the inner peripheral surface of the temporary water retention wall 21, the swirling flow becomes a vortex that is centered on the virtual rotation axis AX <b> 1 that passes through the lower drainage outlet 22 and is directed vertically. In the vortex of the drainage water temporarily accumulated in the temporary water retention unit 20, as shown in FIG. 6 (b), foreign matters such as the hair H <b> 1 swirl and gather while floating, and the hair H <b> 1 from the lower drainage outflow unit 22. Etc. are suppressed. Of course, even if the hair H1 or the like is about to flow out from the lower drainage outflow portion 22, the hair H1 or the like flows out by being caught by the lower drainage outflow portion 22 and the hair removal member main body 82 formed with the plurality of drain holes 23 and 83. Deterred.

  Further, when waste water exceeding the drainage outflow rate of the lower drainage outflow portion 22 flows into the temporary water retention portion 20, the wastewater does not enter the temporary water retention portion 20, exceeds the upper edge portion 21 a, and flows out from the upper drainage outflow portion 30. FIG. 6B shows that the drainage has risen to the position L1 beyond the upper edge portion 21a. At this time, the wastewater that has flowed out from the lower drainage outflow portion 22 falls in the flow direction D14 to the sealing surface S, and the drainage that has flowed out from the upper drainage outflow portion 30 falls in the flow direction D15 to the sealing surface S. Here, since the hair and the like in the drainage water in the temporary water retention unit 20 gather and float and swirl, there are few hairs and the like trying to flow out from the hole 32 of the upper drainage outflow part. Moreover, even if the hair H1 or the like is about to flow out from the upper drainage outflow portion 30, the outflow of the hair H1 or the like is suppressed by being caught by the upper drainage outflow portion 30 in which the plurality of holes 32 are formed. Therefore, the upper drainage outflow portion 30 is different from an opening through which hair or the like flows out, such as an overflow opening provided in a conventional hair catcher.

When the drainage does not flow into the temporary water retention unit 20, the drainage collected by the floating hair H1 and the like flows out from the lower drainage outflow unit 22 and temporarily stays in the state where the hair H1 and the like are gathered as shown in FIG. 6 (c). It remains in the water retention unit 20. When the collected hair or the like is discarded, after removing the cover 120 from the drainage basin 112, the user may hold the handle 86 and remove the hair removing member 80 from the hair catcher body 10 and turn it over. Since the hair H1 and the like are present in the temporary water retention unit 20 in a state of being gathered, the hair H1 and the like are removed from the temporary water retention unit 20 by the operation of removing the hair removing member 80, and the hair is removed from the temporary water retention unit 20 turned upside down. Etc. fall easily.
If the drainage is made to pass through the hair catcher quickly as in the conventional example shown in FIG. 13 (c), it will be difficult for the hair etc. to get entangled with the hair catcher, but this hair catcher 2 Since the wastewater gradually passes through the lower drainage outflow portion 22, good hair removability can be obtained and cleaning is easy.

  Further, in the conventional example shown in FIGS. 13 (a) to 13 (c), it is necessary to take out the entire hair catcher from the drain trap in order to discard the hair and the like. There is no need to take it out of. That is, the hair removing member 80 is removed from the hair catcher body 10 to remove the hair H1 and the like from the temporary water retaining portion 20, and the hair removing member 80 can be turned over to throw away the hair H1 and the like. Becomes easy.

Furthermore, when all the drainage from the washing area passes through the entire hair catcher at once as in the conventional example shown in FIGS. 13 (a) to (c), the hair and the like easily adhere to the entire hair catcher and become clogged. Since the hair catcher 2 does not directly flow into the upper drainage outflow portion 30, the hair catcher 2 can prevent the upper drainage outflow portion 30 from being blocked and obtain a stable drainage capacity.
In addition, in the conventional example shown in FIGS. 13A to 13C, it is necessary to generate a vortex by making a sealed tube, a drainage tub, etc. a special structure. Hair removal performance and stable drainage ability can be obtained only with the structure of the hair catcher alone. In particular, in the conventional example shown in FIGS. 13 (a) and 13 (b), the drainage capacity is limited by passing all the drainage from the washing place through the drainage amount adjusting component 904. According to the hair catcher 2, however, Since there is no need to limit the capacity, a stable drainage capacity can be obtained. Further, in the conventional example shown in FIG. 13 (c), bathtub drainage is necessary to generate eddy currents, but this hair catcher 2 is good only by draining from a washroom such as a washroom shower without using bathtub drainage. Hair removability can be obtained.
Therefore, according to the present hair catcher 2, there is no need to provide a special structure for the drain trap provided with the hair catcher, and it is possible to obtain a good hair removal property, a good cleaning property, and a stable drainage capability, such as hair easily. Can be thrown away. Of course, these performances can be obtained by replacing only the hair catcher from the existing drain trap. Accordingly, the drain trap can be made inexpensive.

  In addition, when there is little waste water flowing in from the washing place, a swirl flow may not be generated in the temporary water retention unit 20, but even in this case, hair etc. floats in the waste water temporarily accumulated in the temporary water retention unit 20. Collecting, the outflow of hair and the like from the lower drainage outflow portion 22 is suppressed. Of course, even when the inflowing wastewater is so small that it is not temporarily retained in the temporary water retaining portion 20, the lower drainage outflow portion 22 having a plurality of drain holes 23 prevents outflow of hair and the like. Since the waste water gradually flows out from the outflow portion 22, a reduction in hair removability due to entanglement of hair or the like is suppressed.

  Since the hair catcher body 10 of the present embodiment includes the above-described temporary water retention unit 20, the upper drainage outflow unit 30, and the drainage introduction unit 40, it is possible to obtain good hair removal performance even when the hair removal member 80 is not attached. Good cleanability and stable drainage capacity can be obtained. Therefore, the usage method of attaching the hair removing member 80 to the hair catcher body 10 and the usage method of not attaching it can be selected according to the preference of the person who performs the operation of discarding hair or the like.

(2) Second embodiment as a reference example :
7 is a vertical sectional view showing a bathroom drain trap 1 provided with a hair catcher 202 according to a second embodiment as a reference example , FIG. 8 is an exploded side view of the hair catcher 202, and FIG. 9 is a hair. FIG. 10 (a) is a plan view of the catcher 202, FIG. 10 (a) is a side view showing the hair catcher body 210 with the hair removing member 280 attached, as viewed from the direction corresponding to A1 in FIG. 3, and FIGS. FIG. 4 is a vertical sectional view showing a hair catcher main body 210 to which a member 280 is attached as viewed from a position corresponding to A2-A2 in FIG. 3. Since the configuration of the drain trap 201 other than the hair catcher 202 is the same as that of the first embodiment, the description other than the hair catcher 202 is omitted.
The hair catcher 202 includes a hair catcher main body 210 and a hair removing member 280 that is detachably attached to the hair catcher main body. The hair catcher 202 includes a temporary water retention unit 220, an upper drainage outflow unit 230, and a drainage introduction unit 240 in a state where the hair removal member 280 is attached to the haircatcher main body 210, and in this state, collects dust such as hair from the drainage. To do. In the present embodiment, the temporary water retention unit 220 is configured by the hair removing member 280, and the upper drainage outflow unit 230 and the drainage introduction unit 240 are configured by the hair catcher body 210.

  The hair removing member 280 has a temporary water retention part 220 attached to the lower part of the hair catcher body 210 and a handle 286 protruding from the upper edge 221a of the temporary water retention part.

  The temporary water retention unit 220 is formed of a flexible material in a concave shape in which the apex and ridge line of the inverted quadrangular pyramid are rounded, and the inner surface near the upper edge 221a is a vertical surface. A plurality of drain holes 223 are formed in the lower portion of the temporary water retaining portion 220 near the apex of the quadrangular pyramid, and a lower drainage outflow portion 222 that drains the drainage substantially downward while suppressing the outflow of hair and the like during drainage. Has been. The periphery of the lower drainage outflow part 222 in the temporary water retention part 220 is a wall part 221 having no drainage hole, rises obliquely toward the outside, and is connected to a vertical surface in the vicinity of the upper edge part 221a. The upper edge portion 221a extends slightly outward in the horizontal direction and is placed on the lower flange portion 235 of the hair catcher body 210. On the outer surface of the wall portion 221, a plurality of protrusions 284 are formed at positions that are spaced from the upper edge portion 221a with a space sandwiching the lower flange portion 235 therebetween.

  The lower part of the hair catcher main body 210 is provided with an opening 234 for attaching the temporary water retention part 220, and a lower flange part 235 extending slightly inward in the horizontal direction is formed. When the temporary water retaining portion 220 is inserted into the opening 234 from above, the plurality of protrusions 284 get over the lower flange portion 235, and the hair removing member 280 is attached to the hair catcher body 210. Further, when the handle 286 is held and lifted by hand, the plurality of protrusions 284 get over the lower flange portion 235 and the hair removing member 280 is removed from the hair catcher body 210.

The upper drainage outflow portion 230 extends from the lower flange portion 235 so as to rise obliquely outward, and a plurality of holes 32 through which drainage flows out while suppressing the outflow of hair are formed. Since the upper drainage outflow portion 230 drains the wastewater that does not enter the temporary water retention unit 220, the maximum drainage outflow rate Qu of the upper drainage outflow portion 230 is set to be larger than the maximum drainage outflow rate Qd of the lower drainage outflow portion 222. Yes.
The maximum drainage outflow rates Qd and Qu of the lower drainage outflow portion 222 and the upper drainage outflow portion 230 can be set in the same manner as in the first embodiment.

  The drainage introduction part 240 has the same parts 50, 60, 70 as in the first embodiment, and directly drains water from the washing place W1 so that a swirling flow that rotates counterclockwise in the temporary water retention part 220 is generated. Guide to temporary water retention unit 220.

Next, the operation and effect of the hair catcher 202 will be described. The hair removing member 280 is assumed to be attached to the hair catcher main body 210.
Drainage that flows into the drainage basin 112 from the washing station W1 flows down mainly onto the hair catcher flange part 70, is guided in the flow directions D21 and D22, and increases in speed toward the temporary water holding part 220 on the inclined part 60. However, it flows in the flow direction D23. The drainage flows into the concave temporary water retention unit 220 toward the position shifted in the horizontal direction from the center of gravity CE2 of the plan view of the lower drainage outflow portion 222 projected on the virtual horizontal plane HP2, and passes through the lower drainage outflow portion 222. A counterclockwise swirl flow (rotation direction D2) centering on a virtual rotation axis AX2 oriented vertically is generated and flows downward from the lower drainage outflow portion 222. In the swirl of the wastewater temporarily accumulated in the temporary water retention unit 220, foreign matter such as hair H1 swirls and gathers while floating, as shown in FIG. 10 (b), and the hair H1 from the lower drainage outflow portion 222 gathers. Etc. are suppressed. Further, when drainage exceeding the drainage outflow rate of the lower drainage outflow unit 222 flows into the temporary water retention unit 220, the drainage does not enter the temporary water retention unit 220 and flows out from the upper drainage outflow unit 230 while the outflow of hair H1 and the like is suppressed. To do. FIG. 10B shows that the drainage has risen to the position L2 beyond the upper edge 221a. At this time, the drainage discharged from the lower drainage outflow portion 222 falls in the flow direction D24, and the drainage discharged from the upper drainage outflow portion 230 falls in the flow direction D25. Since the hairs and the like in the drainage water in the temporary water retention unit 220 are gathered, floated, and swirled, there are few hairs and the like trying to flow out from the holes 232 of the upper drainage outflow part.

When the drainage does not flow into the temporary water retention unit 220, the drainage collected by the floating hair H1 and the like flows out from the lower drainage outflow unit 222, and temporarily stays in a state where the hair H1 and the like are gathered as shown in FIG. It remains in the water retention unit 220. When the collected hair or the like is discarded, after removing the cover 120 from the drainage basin 112, the user can hold the handle 286 and remove the hair removal member 280 from the hair catcher body 210 and turn it over. Since the hair H1 and the like are present in the temporary water retention unit 220 in a state of being gathered, the hair H1 and the like are removed from the drain trap 201 by the operation of removing the hair removal member 280, and the hair etc. from the temporary water retention unit 220 turned upside down Will fall easily.
In addition, the hair catcher 202 does not flow directly into the upper drainage outflow portion 230.
Therefore, according to the present hair catcher 202, it is not necessary to provide a special structure in the drain trap where the hair catcher is provided, and it is possible to obtain a good hair removal property, a good cleaning property, and a stable drainage capability, and the hair easily Can be thrown away.

(3) Modification:
Various modifications can be considered for the hair catcher of the present invention.
The direction of the hair catcher with respect to the washing place and the bathtub is not limited to the above-described embodiment, and can be changed to all 360 degrees about the virtual rotation axes AX1 and AX2 oriented vertically, for example. Therefore, the inflow port through which the wastewater from the washing place is passed to the temporary water holding part may be arranged on the bathtub side in addition to being arranged on the washing area side as in the above-described embodiment, or between the washing area side and the bathtub side. It may be arranged at an intermediate position or the like.
In addition to the gap provided in the standing wall, the inflow port through which the wastewater from the washing place is passed to the temporary water holding unit may be an opening provided in these parts.
The temporary water retaining portion may be formed in a hemispherical shape or a concave shape in which the top of an inverted cone is rounded. Then, it is thought that drainage becomes a swirl flow easily in the temporary water retention part, and it is considered that hair and the like can be more easily discarded.
The lower drainage outflow part and the upper drainage outflow part can be formed by a net formed by knitting fibers or wires, etc., or can be formed by a plurality of slits, in addition to being formed by a plurality of holes. is there.
In addition to the shape extending in the vertical direction, the standing wall portion disposed outside the upper drainage outflow portion may have a shape extending in a direction shifted from the vertical direction.

The swirl flow generated in the temporary water retention unit by the drainage introduction unit may be clockwise as opposed to the above-described embodiment. Further, the direction of the rotational axes AX1 and AX2 of the swirling flow may be a direction obliquely shifted from the vertical direction or a horizontal direction.
The direction in which the drainage introduction part guides drainage into the temporary water retention part can be other than the direction along the inner peripheral surface of the temporary water retention part wall part. For example, if the direction of leading the drainage is a direction toward the lower drainage outflow part, it is considered that a swirling flow is generated with the rotation axis oriented horizontally in the temporary water retention part. Also in this case, it is considered that hair or the like floats and gathers while floating in the temporary water retaining portion, and remains in the temporary water retaining portion in a state where the hair or the like is gathered, so that good hair removability can be obtained.
In the case where the temporary water retention part is in the shape of a pyramid that is upside down or rounded at the apex and ridge line of the upside down pyramid, the drainage introduction part is along the side of the horizontal section of the wall part of the temporary water retention part You may guide the drainage from the washroom in the direction.

  Even when the waste water introduction part guides the waste water from the washing place to the temporary water holding part so that the swirling flow is not generated, the hair etc. floats and gathers in the waste water temporarily accumulated in the temporary water holding part, and the lower drainage outflow part When the drainage drains from the water, it remains in the temporary water retaining portion in a state where the hair is collected. Therefore, the effect of obtaining good hair removability and stable drainage ability is obtained.

  Since the basic effect of the present invention can be obtained if the drainage introduction part guides the wastewater from the washing place to the temporary water retention part, a hair catcher or the like that does not have the flange part 70 also exhibits the effects and effects of the present invention. .

Various modifications can be considered for the hair removal member and the hair catcher body.
For example, like the hair catcher 302 shown in FIG. 11A, a hair removing member 380 having an opening 383 larger than the drain hole 23 of the hair catcher main body formed in the lower portion of the main body 382 is provided to the hair catcher main body 10. You may attach so that attachment or detachment is possible. Although the hair removal member 380 itself is not formed so as to prevent the outflow of hair during drainage, the lower drainage outflow portion 22 of the hair catcher main body suppresses the outflow of hair during drainage. Hair remains. Then, when the hair removal member 380 is removed from the hair catcher body 10 while holding the handle 386 by hand, the hair remaining in the temporary water retention unit 20 is removed.

  Moreover, like the hair catcher 303 shown in FIG.11 (b), hair removal is carried out with respect to the hair catcher main body 310 which formed the opening 323 larger than the drain hole 83 of the hair removal member in the lower part of the main body side temporary water retention part 320. The member 80 may be detachably attached. Although the main body-side temporary water retaining portion 320 is not formed so as to suppress the outflow of hair during drainage, the plurality of drain holes 83 of the hair removal member suppress the outflow of hair during drainage, and the main body of the hair removal member Drainage is temporarily retained in the body-side temporary water retention unit 320 to which the unit 82 is attached. That is, in this modification, the main body part 82 of the hair removing member and the main body side temporary water retention part 320 of the hair catcher main body serve as the temporary water retention part referred to in the present invention. Of course, when the hair removal member 80 is removed from the hair catcher body 310 while holding the handle 86 by hand, the hair is removed from the drain trap.

  Furthermore, like the hair catcher 402 shown in FIG.11 (c), you may attach to the hair catcher main body 210 the hair removal member 480 except a processus | protrusion (284) from the hair removal member (280) of 2nd embodiment. . Since the upper edge portion 221a that slightly extends outward in the horizontal direction in the hair removing member 480 is placed on the lower flange portion 235 of the hair catcher body 210, the hair removing member 480 can be attached to and detached from the hair catcher body 210. It is attached.

Furthermore, a part of the upper drainage outflow portion may be provided on the above-described hair removal member, and the remaining upper drainage outflow portion may be configured by a hair catcher body. Of course, a part of the drainage introduction part may be provided on the hair removing member, and the remaining drainage introduction part may be constituted by the hair catcher body.
In addition, the hair catcher of the present invention only needs to be configured with at least a temporary water retention portion, an upper drainage outflow portion, and a drainage introduction portion in a state in which the hair removing member is attached to the haircatcher body, and portions other than these portions are further configured. May be. As such a configuration, a structure for attaching the hair catcher body to a tightening flange or a water seal can be considered.

Further, as in the case of the hair catcher 502 shown in FIG. 12A and the hair catcher 602 shown in FIG. 12B, convex portions 524 and 624 projecting upward may be provided at the bottoms of the temporary water holding portions 520 and 620. Good. These temporary water retaining portions 520 and 620 are provided with lower drainage outflow portions 522 and 622 each having a plurality of drain holes 523 and 623 around the convex portions 524 and 624. In the hair catcher 502 of FIG. 5A, the hair removing member 580 is also provided with a convex portion 584, and a plurality of drain holes 583 are formed around the convex portion 584. The hair removing member 580 is detachably attached to the inner surface of the temporary water retention unit 520 of the hair catcher main body 510 with the convex portions 524 and 584 overlapped, and remains in the temporary water retention unit 520 by an operation of removing from the temporary water retention unit 520. The hair can be removed. In the hair catcher 602 in FIG. 5B, the temporary water retaining portion 620 having the convex portion 624 is constituted by the hair removing member 680, and the hair can be removed by the operation of removing the hair removing member 680 from the hair catcher body 210. . Even in these modified examples, the hair etc. floats and collects in the drainage water temporarily stored in the temporary water retention part, and remains in the temporary water retention part in a state where the hair etc. is gathered, and has good hair removability and stability. The effect of obtaining drainage capacity is obtained.
Furthermore, the convex part provided at the bottom of the temporary water retaining part may be a part that bulges upward.
