Description

  The present invention relates to a drainage plate (hair catcher) that has a dust collecting part that collects hair, fiber waste, and other garbage, and is installed in a drainage part of a bathroom or a vanity, for example.

  Conventionally, a drainage pan 80 configured as shown in FIG. 6A is known as a device that is attached to a drain outlet of a bathroom and collects hair and other garbage through only drainage. The drainage pan 80 includes an annular flat flange portion 82, a mesh drainage hole 81 which is an inner collection portion thereof, and an overflow drainage cylinder 83 at the center thereof. A handle 84 is provided that stands and extends horizontally outward at the upper end.

  Similarly, in a hair catcher installed at a drain outlet of a bathroom, a tube part is raised from an edge of a dust collecting surface, and a handle is provided at the upper end of the tube part (see Patent Document 1). . Moreover, in the hair catcher installed in the drain outlet of a bathroom, a handle is bendable, and the tongue-shaped handle is used upright when attaching / detaching from the drain outlet (see Patent Document 2).

JP 2007-211152 A JP 9-256439 A

  When the handle portion 84 stands up from the flange portion 82 and is provided above the mesh drainage hole 81 as in the conventional drainage tray 80 shown in FIG. 6A, the hand touches the mesh drainage hole 81. Because there is not, we can throw away garbage sanitarily. However, there is a problem that dust such as hair that flows along with the drainage flowing into the drainage pan 80 from the outside of the handle portion 84 is likely to get entangled with the handle portion.

  FIG.6 (b) shows the state which mounted | wore the adapter 10 for attaching the drainage pan 80 to a drain outlet. When the handle portion 84 is formed upright from the flange portion 82, the drainage flowing from the outer surface side of the handle portion 84 is blocked by the handle portion 84 immediately above the gap 48 between the flange portion 82 and the adapter 10. As a result, stagnant water 85 is generated, and the hair 15 tends to flow into the gap 48 together with the drainage and become clogged or tangled.

  The present invention makes it difficult for trash such as hair flowing along with the drainage to get entangled with the handle portion standing up from the flange portion of the drainage pan, and the hair flows out and becomes clogged with the drainage from the gap between the flange portion and the adapter. It is possible to remove collected litter from the collection part at the time of cleaning the drainage dish so that it is collected as much as possible in the collection part of the drainage dish, and easy to handle. The objective is to realize a simple drainage pan.

  In order to solve the above-mentioned problems, the present invention provides a drainage pan equipped with a dust collecting portion, a flange portion formed around the collecting portion, and a handle portion formed upright from the flange portion. A drainage pan is provided, wherein a groove having a curved cross section is formed on the outer peripheral surface of the upright portion of the handle portion.

  It is preferable that the groove is formed substantially horizontally along the outer peripheral surface of the handle portion over the entire width of the handle portion.

  It is preferable that the depth of the groove is larger in the lower part than in the upper part.

  It is preferable that the handle portion is formed in a substantially trapezoidal shape when viewed from the front.

  Since the drainage pan of the present invention has a groove with a curved vertical cross section formed on the outer peripheral surface of the standing portion of the handle portion, dust such as hair that flows along with the drainage can be removed from the handle and the drainage pan. It becomes difficult to get entangled or clogged with the attachment part to the drainage outlet, and it becomes easy to collect garbage such as hair intensively in the collection part, so it is easy to remove the collected garbage when cleaning the drainage pan Become.

  As shown in FIGS. 1A, 1 </ b> B, and 2 </ b> B, projecting edges 7 are formed on two lower surfaces of the flange portion 3 in the circumferential direction. The projecting edge 7 has an L-shaped cross section so as to project downward from the lower surface of the flange portion 3 and project horizontally outward at the lower end, and in plan view along the outer surface of the annular upper peripheral wall 8 described later. It is formed in a curved shape. As will be described later, the protruding edge 7 is fitted into the receiving groove 11 of the adapter 10 when the drain pan 1 is attached to the drain outlet 6 via the drain case 9 and the adapter 10. As a result, the drain pan 1 is attached to the drain outlet 6 so that the flange portion 3 is substantially flush with the adapter 10 (see FIG. 4B). In the first embodiment, the protruding edge 7 is provided on two lower surfaces in the circumferential direction. However, the protruding edge 7 is not particularly limited to two, and the adapter 10 to which the drainage case 9 is attached is not limited. You may provide in more places according to the number in which the receiving groove 11 is formed.

  The collection part 2 is good also as a structure which has several step part, and is good also as a simple dish-like structure, without having a several step part. In the first embodiment, the collection unit 2 will be described with a configuration having a plurality of steps, but as the plurality of steps, there are two steps, an upper step 12 and a lower step (bottom) 13. . In addition, the collection part which does not have a several step part is demonstrated in Example 2 mentioned later.

  As shown in FIGS. 1 (a), 2 (a), and 3 (a), the flange portion 3 has an annular upper peripheral wall 8 via a bent portion 14 bent downward at the inner peripheral edge thereof. Connected continuously. Then, it is bent horizontally from the lower end of the upper peripheral wall 8 and is continuously connected to the upper step portion 12. In the drain pan 1, the upper step portion 12 is a so-called intermediate step portion positioned at a height between the flange portion 3 that is the uppermost portion and the lower step portion 13 that is the lowermost portion.

  The upper part 12 of the collecting part 2 does not directly capture the dust such as hair like the lower part 13, but drains the waste water along the upper part 12 so that the dust such as hair flows. By guiding to the lower stage 13 while floating, it has an auxiliary function that makes it easy to collect dust such as hair 15 in a batch at the lower stage 13.

  In the first embodiment, as shown in FIG. 1A and FIG. 2A, a plurality of drain holes 16 are formed in the upper stage 12 at intervals in the circumferential direction. Part of the drainage flowing along is configured to pass. However, the upper stage 12 may have a configuration in which the drain hole 16 is not provided. Whether or not the drain holes 16 are provided, and when the drain holes 16 are provided, the number, shape, position, etc., of the place where the drain pan 1 is installed (eg, bathroom wash basin, wash bowl) It is a matter appropriately designed by.

  The upper step portion 12 is bent downward from the inner peripheral edge thereof and continuously connected to the lower peripheral wall 17, and the lower end of the lower peripheral wall 17 is bent horizontally and continuously connected to the lower step portion (bottom portion) 13. ing. The lower peripheral wall 17 is formed of a vertical surface or an inclined surface, and a plurality of drain holes 18 are formed in the upper portion thereof at intervals in the circumferential direction. Although not shown, the lower peripheral wall 17 may not have such a drain hole 18.

  The lower step portion 13 is a portion corresponding to the bottom portion of the drainage pan 1, and a plurality of annular ribs 19 are formed on the upper surface so as to be concentrically convex upward, and between the adjacent ribs 19. A plurality of drain holes 21 are formed at intervals in the circumferential direction. The lower stage portion 13 has a function of collecting waste while discharging the drainage through the drainage hole 21. The rib 19 has a function of making the collected dust less likely to adhere to the surface of the lower stage portion 13, improving the cleanability of the drainage pan 1, and improving the strength of the collection portion 2.

  As shown in FIGS. 1 (a), 2 (a), 2 (b) and 3 (a), the handle portion 4 is formed upright from the upper surface of the flange portion 3. The part that rises (the part that rises) is referred to as the “standing part”, and the part that extends upward above the rising part 20 is referred to as the upper part 22 of the handle part 4. As shown in FIGS. 1A and 1B, the handle portion 4 is formed in a substantially trapezoidal shape with a lateral width (width in the circumferential direction) gradually decreasing upward in a front view. And the upper end of the upper part 22 of the handle part 4 is bend | folded substantially horizontally toward the radial direction outer side, and the knob | pick part 23 used as a finger hook is formed.

  As shown in FIG. 2A, the outer peripheral surface (back surface) 24 of the handle portion 4 is formed in a curved shape in plan view so as to follow the outer peripheral edge 26 of the flange portion 3. A groove 25 having a curved vertical section is formed on the outer peripheral surface 24 of the upright portion 20 of the handle portion 4 as shown in the cross-sectional views of FIGS. The curved groove 25 is formed substantially horizontally along the outer peripheral surface 24 of the handle portion 4 over the entire circumferential width of the handle portion 4.

  In other words, the upright portion 20 rises on the outer peripheral surface 24 via the groove 25 whose vertical cross section from the outer peripheral edge 26 of the flange portion 3 toward the radial center of the drainage pan 1 is curved (concavely curved). It has been. The curvature radius R of the groove 25 is constant (for example, 3 mm or more).

  The deepest bottom portion of the groove 25 (in the cross-sectional view of FIG. 3B), the bottom portion of the groove 25 farthest in the horizontal direction from the outer peripheral edge 26 or the upper edge 30 of the flange portion 3 in the cross section. Is the bottom 27, the lower part of the groove 25 is the lower part 28 of the groove 25, and the upper part of the groove 27 is the upper part 29 of the groove 25, the radius of curvature of the curved surface of the lower part 28 of the groove 25 is It is good also as a structure formed slightly smaller than the curvature radius of the curved surface of the upper part 29 of the groove | channel 25. FIG.

  The depth of the groove 25 in the horizontal direction is deeper in the lower part of the groove 25 than in the upper part of the groove 25. That is, in FIG. 3B, the distance (depth) d1 from the outer peripheral edge 26 (lower edge of the groove 25) of the flange portion 3 to the bottom 27 of the groove 25 is the upper edge 30 of the groove 25 to the bottom of the groove 25. It is formed larger than the distance (depth) d2 up to 27. In the standing part 20, the outer peripheral surface 24 is formed so as to be continuously connected to the upper part 22 of the handle part 4 from the outer peripheral edge 26 of the flange part 3 through the groove 25, thereby The handle portion 4 is formed upright while being retracted inward from the outer peripheral edge 26, and a space 31 including the groove 25 is formed outside the handle portion 4 (see FIGS. 3A and 3C). ).

  By providing such a space 31, drainage is not blocked by the handle portion 4 immediately above the gap 48 between the flange portion 3 and the adapter 10, and flows from the outer surface side of the handle portion 4. Since the waste water flows from the space 31 into the groove 25, the hair 15 does not easily flow into the gap 48 together with the waste water and become clogged or entangled with the handle portion 4 (see FIG. 3C).

(Function)
Means for mounting the drainage pan 1 having the above configuration to the drain outlet 6 and the operation of the drainage pan 1 will be described below with reference to FIG. After installing the drainage case 9 at the drainage port 6, the drainage pan 1 is attached to the drainage case 9 via the adapter 10 and attached to the drainage port 6. For this purpose, first, as shown in FIG. 4A, a shelf portion 38 formed in the drainage port 6 is interposed between the flange 35 of the drainage case 9 and the flange 36 of the adapter 10 via a seal 37. The state is sandwiched.

  Then, the screw 40 formed on the outer peripheral surface of the adapter 10 is screwed onto the screw 39 formed on the inner peripheral surface of the flange 35 of the drainage case 9 to tighten the shelf portion 38 so that the adapter 10 is tightened. Fastened to the flange 35 of the drainage case 9. Thereby, the drainage case 9 is installed in the drain outlet 6. A drain cylinder 41 having an open lower end is mounted in the drain case 9 so that the upper end flange 42 is hooked on the lower end flange 44 of the adapter 10 via a seal 43.

  Then, as shown in FIG. 4 (b), the curved protruding edge 7 of the drain pan 1 is inserted into the receiving groove 11 formed in the circumferential direction on the inner surface of the adapter 10 so as to be horizontally rotated. Then, the drainage pan 1 is attached to the adapter 10. Thereby, the drainage pan 1 can be attached to the drainage case 9.

  As shown in FIG. 4 (b), the waste water that has flowed into the drain port 6 from the periphery of the drain lid 45 flows into the drain pan 1 from the flange portion 3 and is guided by the upper peripheral wall 8 to the surface of the upper step portion 12. Flowing along. Further, the drainage flows down from the upper stage 12 to the lower stage 13, passes through the plurality of drain holes 21, and is discharged into the drain tube 41. The drainage flows from the lower side of the drainage cylinder 41 to the outside beyond the weir 46 of the drainage case 9 and is discharged from the discharge pipe 47 to a drainage channel or the like.

  Garbage such as hair that flows into the drainage pan 1 together with the drainage and cannot pass through the drainage hole 21 of the lower stage 13 is collected by the lower stage 13. Then, when cleaning the drainage pan 1, the drainage pan 1 may be removed from the adapter 10 to remove the dust collected in the lower stage 13 or the like.

  As shown in FIG. 3A, the drain pan 1 of the present invention has a groove 25 formed on the outer peripheral surface 24 of the standing portion 20 of the handle portion 4, and the flange portion 3 via the groove 25. The outer peripheral edge 26 is connected to the outer peripheral surface 24 of the upper portion 22 of the handle portion 4, and a space 31 is formed. Since the handle portion 4 has such a configuration, the drainage flowing from the outer surface side of the handle portion 4 flows into the groove 25 from the space 31 as shown by the white arrow in FIG. A part of the drainage flows laterally along the surface of the groove 25 and flows into the upper stage portion 12. When the amount of drainage is small, the drainage is flowed to the collection unit 2 in this way. However, when the amount of drainage is large, the drainage rises along the groove 25 along the groove 25 and the outer peripheral surface of the handle unit 4. It stays outside 24, and flows out to the side along the outer peripheral surface 24 of the handle portion 4 and flows into the upper stage portion 12.

  Therefore, when the amount of drainage is small, the hair 15 that has flowed along with the drainage flows along with the drainage that flows laterally through the groove 25 and is directed toward the upper stage portion 12. In addition, when the amount of drainage is large, in addition to this, the hair 15 rises in the groove 25 together with the drainage, and floats in the drainage that stays along the outer peripheral surface 24 of the handle 4, while the handle 4 Is flowed to the side along the outer peripheral surface 24 of the rim, and is directed toward the upper stage portion 12. For this reason, the drainage is not blocked by the handle portion 4 immediately above the gap 48 between the flange portion 3 and the adapter 10, and as a result, the hair 15 flows into the gap 48 together with the drainage and becomes clogged. Or it becomes difficult to get entangled with the handle part 4.

  In addition, as shown in FIGS. 1 (a) and 1 (b), the drain pan 1 of the present invention has a substantially trapezoidal shape when viewed from the front, and is gradually widened toward the top (circumferential direction). The width is reduced. For this reason, as described above, the drainage that rises in the groove 25 and stays along the outer peripheral surface 24 of the handle portion 4 gradually increases in width from the side of the handle portion 4 that gradually decreases in width. It will be easy to be swept away by wrapping around (or leaking out) towards 12. As a result, the hair 15 that has flowed along with the drainage is also likely to flow while floating in the drainage, is effectively guided toward the upper stage portion 12, and is not easily entangled with the handle portion 4.

  As described above, in the drainage pan 1 of the present invention, the hair 15 that has flowed together with the drainage from the outer surface side of the handle portion 4 is clogged by the hair 15 flowing into the gap 48 together with the drainage, or entangled with the handle portion 4. The upper stage 12 is floated in the drainage from the flange part 3 and is effectively guided to the lower stage 13 while turning around. Accordingly, since dust such as hair 15 is likely to gather in the lower stage portion 13, it is possible to easily remove dust collectively when cleaning the drainage pan 1.

  5 (a) and 5 (b) are diagrams illustrating Example 2 of the drainage pan according to the present invention. The drain pan 51 of the second embodiment has substantially the same configuration as the drain pan 1 of the first embodiment, and in particular the configuration of the handle portion is the same, but the configuration of the collecting section is different.

The collecting portion 52 is an example that does not have a plurality of steps.

  The flange portion 53 is continuously connected to the annular peripheral wall 55 via a bent portion 56 that is bent downward at the inner peripheral edge thereof. Furthermore, the peripheral wall 55 is continuously connected to the collection part (bottom part) 52. The peripheral wall 55 is formed so as to be inclined so that the diameter gradually decreases from the flange portion 53 to the collecting portion 52.

  In the second embodiment, a configuration is shown in which a plurality of drain holes 58 are formed in the upper portion of the peripheral wall 57 at intervals in the circumferential direction. However, a drain hole 58 may be formed in the peripheral wall 55 in accordance with the location where the drain pan 50 is to be installed (for example, a bathroom washroom, a wash bowl, etc.) and the amount of drainage at the drain outlet. However, it may be configured not to be formed.

  The collection part (bottom part) 52 of the drainage dish 51 is the same structure as the lower step part (bottom part) 13 of the drainage dish 1 of Example 1, and a plurality of annular ribs 59 are concentrically arranged on the upper surface. A plurality of drain holes 60 are formed at intervals in the circumferential direction between the ribs 59 adjacent to each other. The collection part 52 has a function of collecting wastes such as hair flowing along with the drainage while discharging the drainage through the drainage hole 60.

  In the second embodiment, the handle portion 54 is provided on the flange portion 53 as in the first embodiment, and a groove 57 is formed on the outer surface thereof. In addition, the drainage pan 51 of the second embodiment has a drainage case 9 and an adapter having the same construction as the mounting structure of the drainage pan 1 to the drain outlet 6 in the first embodiment (see FIG. 4). 10 is used by being attached to the drain port 6 through 10.

  As mentioned above, although the form for implementing the drain pan according to this invention was demonstrated based on the Example, this invention is not limited to such an Example, The technique described in the claim It goes without saying that there are various embodiments within the scope of the subject matter.

  Since the drain pan according to the present invention is configured as described above, it can be applied not only to a drain outlet provided on the floor of a bathroom washing place, but also to a drain outlet such as a wash bowl and a kitchen sink.
