Description

  The present invention relates to a drainage eye plate (hair catcher) that has a dust collection unit that collects hair, fiber scraps, and other garbage, and is installed in a drainage unit such as a bathroom washroom or a wash bowl.

  2. Description of the Related Art Conventionally, a drainage pan having a structure as shown in FIG. 7A is known as a device that is attached to a drainage part of a bathroom and collects hair and other garbage through only drainage. This drain pan 40 has a function of attaching to a drain outlet and has a flat flange portion 42 having a mesh drainage hole 41, an inclined wall surface 43 made of an inverted frustoconical curved surface, and a bottom portion having a mesh drainage hole 44. 45 and a handle 46 provided on the bottom 45. The bottom 45 has a function of draining and a collecting part for collecting garbage.

  In addition, conventionally, in a hair catcher installed at a drain outlet of a bathroom, a configuration is known in which a cylindrical portion is formed from an edge of a dust collecting surface and a handle is provided at the upper end of the cylindrical portion (see Patent Document 1). . Furthermore, in the hair catcher installed at the drain of the bathroom, the upright part is formed by the overflow pipe part protruding upward from the position reserved inward from the outer peripheral edge of the outer peripheral part, and the knob is provided at the upper end part of the upright part. The structure is known (see Patent Document 2).

  By the way, when the conventional drainage pan shown in FIG. 7A has a large amount of drainage and a strong flow momentum, most of the drainage flows to the bottom 45 which is the center of the drainage pan 40 and the mesh drainage holes 44. Since it is discharged through, wastes such as hair flowing simultaneously with the drainage are also guided to the bottom 45 and collected.

  However, when the amount of drainage is small, the drainage is also discharged from the mesh drainage hole 41 of the flange portion 42, so that dust such as hair that flows at the same time is caught by the flange portion 42, the inclined wall surface 43, etc. As a result, there was a problem that the waste was guided to the bottom 45 and deposited and became difficult to collect, and cleaning the drain pan 40 was troublesome.

  In addition, in the inventions described in Patent Documents 1 and 2, since the drainage holes are formed on almost the entire surface of the hair catcher, the garbage is collected by these drainage holes and concentrated in the center of the bottom of the drainage pan. It is considered that it is difficult to collect and remove all at once.

  In order to solve the problems in these conventional examples and Patent Documents 1 and 2, the present inventors have already proposed a drain pan as shown in FIG. 7B as the prior art of the present invention ( (See Japanese Patent Application No. 2009-108694).

  The drainage pan 50 according to the prior art is provided with an annular upper step 53 as an intermediate step between an annular flat surface portion (flange portion) 51 and a lower step portion (bottom portion) 52, thereby reducing the amount of drainage. Even in such a case, the waste water easily flows as a swirl flow, and dust such as hair that flows at the same time is guided to the lower stage 52 at the center of the drainage tray 50 to collect and deposit, and the drainage tray is cleaned. At this time, the collected dust is removed from the lower stage 52 in a lump to facilitate cleaning.

JP 2007-211152 A JP 2009-7778 A

  In the above prior art, by providing the upper step portion 53 as an intermediate step portion, even when the amount of drainage is small, the wastewater flows as a swirling flow, and dust such as hair is guided to the lower step portion 52 that is the center of the drainage pan 50. The effect of facilitating this is produced. However, in this prior art, when the amount of drainage is small, the amount of water staying in the vicinity of the handle portion 55 is reduced, so that the hair 34 is easily entangled with the handle portion 55.

  In the present invention, even when the amount of drainage is small, dust such as hair flowing at the same time as drainage is less likely to get entangled with the flange part and handle part above the drainage pan so that it accumulates as much as possible at the bottom (lower part) that is the center Thus, an object of the present invention is to realize a drainage pan that is easy to handle and can collect collected waste from the bottom at the same time when the drain pan is cleaned.

In order to solve the above-mentioned problems, the present invention stands up from a flange collecting portion, a flange portion formed around the collecting portion, a dust collecting portion having a plurality of step portions of an upper step portion and a lower step portion. In the drainage pan with the handle part to be formed, the outer surface side of the place standing from the flange part in the handle part is located slightly inside the outer edge of the flange part, on the inner surface side of the handle part, above the flange part, and with the convex portion of substantially the same width as the grip portion of the handle portion have a height lower than the gripping portion of the handle portion, it protrudes from the upper portion to the upper, left and right side walls, a front wall and top wall, the handle There is provided a drainage eye dish characterized by being formed in a substantially fan-shaped base shape in a plan view so as to protrude from the inner surface of the part toward the center of the drainage eye dish to the substantially inner edge position of the upper stage part .

  In the drain pan according to the present invention, the convex portion is formed so that the inner surface side of the handle portion is higher than the flange portion. You are guided into the collection. Therefore, it becomes difficult for hair to get entangled or attached to the handle portion, and it becomes easy to remove collected dust from the collecting portion all at once, thereby improving the cleaning property.

  EMBODIMENT OF THE INVENTION The form for implementing the draining pan based on this invention is demonstrated below with reference to drawings based on an Example.

  FIGS. 1-5 is a figure explaining Example 1 of the draining-eye plate based on this invention. The drainage pan 1 according to the present invention includes a flange portion 2, a collecting portion 3 and a handle portion 4, and is generally formed in a substantially dish shape as shown in FIGS.

  The flange portion 2 is formed as an annular flange having a flat surface extending horizontally in the radial direction at the upper end of the drainage pan 1, and is formed on the flange portion 42 of the drainage pan 40 of the conventional example. Such a drain hole 41 (see FIG. 7A) or the like is not formed, and becomes a part for introducing the drainage into the collection unit 3.

  As shown in FIG. 2, the flange portion 2 is continuously connected to the annular upper peripheral wall 6 via a bent portion 5 bent downward at the inner peripheral edge thereof. The upper peripheral wall 6 is formed by a vertical surface or an inclined surface. A protruding edge 7 is formed on the outer surface of the upper peripheral wall 6 in a curved shape along the outer surface. As will be described later, the protruding edge 7 is fitted to the adapter 9 when attached to the drain port 8. As a result, the drain pan 1 is attached to the drain outlet 8 so that the flange portion 2 is substantially flush with the adapter 9 (see FIG. 3B). Although not shown, a plurality of drain holes may be formed at intervals in the circumferential direction, for example, in the upper half of the upper peripheral wall 6.

  The collection unit 3 includes a plurality of steps, and in the first embodiment, a configuration example in which two steps of an upper step 10 and a lower step (collection bottom) 11 are provided as a plurality of steps. To do. The collection part 3 is bent horizontally from the lower end of the upper peripheral wall 6 and is continuously connected to the upper stage part 10. In the drain pan 1, the upper step portion 10 is a so-called intermediate step portion located at a height between the flange portion 2 that is the uppermost portion and the lower step portion 11 that is the lowermost portion. Such an intermediate step portion is provided with only one step of the upper step portion 10 in the first embodiment, but may be configured to have a plurality of steps. Moreover, it is good also as a structure which does not provide the upper step part 10 (intermediate step part).

  In addition, the upper stage part 10 of the collection part 3 does not perform the effect | action which capture | acquires garbages, such as hair directly unlike the lower stage part 11, but it mentions later, but drains the hair etc. so that the upper stage part 10 may be followed. It has an auxiliary function for collection that makes it easy to collect dust such as hair in a lump in the lower stage portion 11 by flowing the dust while floating and guiding it to the lower stage portion 11.

  In the first embodiment, the upper stage portion 10 is provided with a plurality of drain holes 10 ′ so that a part of the waste water flowing along the upper stage portion 10 can pass therethrough. However, the upper stage 10 may be configured not to have a drain hole. Whether or not to provide drain holes, the number and shape of the drain holes are appropriately designed according to the place where the drain pan is installed (eg, bathroom washroom, wash bowl, etc.) and the amount of drainage.

  The upper step portion 10 is bent downward from the inner peripheral edge thereof and continues to the lower peripheral wall 12, and the lower end of the lower peripheral wall 12 is formed horizontally and is continuously connected to the lower step portion 11. The lower peripheral wall 12 is formed by a vertical surface or an inclined surface, and no drain hole is formed.

  The lower stage portion 11 is a portion corresponding to the bottom portion of the drainage pan 1 and has a plurality of drainage holes 11 ′. The drainage holes 11 ′ pass through the drainage holes 11 ′ to discharge wastewater and collect dust. It has a function. A plurality of annular ribs 14 are formed on the upper surface of the lower step portion 11 so as to be concentrically convex upward, and the plurality of drain holes 11 ′ are spaced apart in the circumferential direction between the adjacent ribs 14. Is formed. The rib 14 has a function of making it difficult for the collected dust to adhere to the surface of the lower step portion 11, facilitating removal of the dust when cleaning the drainage pan 1, and improving the strength of the lower step portion 11.

  As illustrated in FIGS. 2A and 2B, the handle portion 4 includes a grip portion 15 and a convex portion 16. The handle part 4 is formed so as to stand upward from a position retracted inwardly from the outer edge of the flange part 2 (center side of the drainage pan 1). In other words, the flange portion 2 is formed so as to stand upward from the vicinity of the inner edge side of the flange portion 2 so that the flat surface of the flange portion 2 sufficiently exists outside the handle portion 4. Further, the convex portion 16 is formed on the inner surface side of the handle portion 4 so as to protrude above the flange portion 2 and below the grip portion 15 above the upper step portion 10.

  As shown in FIGS. 1A, 1 </ b> B, and 2 </ b> B, the convex portion 16 includes left and right side walls 17, a front wall 18, and a top wall 19. It is formed in a substantially fan-shaped base shape in plan view so as to project to the position of the inner edge of the upper stage portion 10 toward the center of the dish 1. The convex portion 16 and the grip portion 15 are formed so that the circumferential width of the drainage pan 1 is substantially the same at the portion where they are coupled to each other.

  The front wall 18 is raised from the inner edge portion of the upper step portion 10, is formed as a curved surface along the inner edge of the upper step portion 10, and the upper end is continuously connected to the flat top wall 19. The left and right side walls 17 are raised substantially vertically from the upper step portion 10 so as to close the left and right sides of the convex portion 16, and are connected to the front wall 18 continuously at the front end thereof, and the top wall at the upper end thereof. 19 is continuously connected to the upper peripheral wall 6 at the rear end.

  The height of the convex portion 16, specifically, the height of the top wall 19 is formed higher than the upper surface of the flange portion 2. A through-hole 20 is formed in the top wall 19 so as to penetrate in the vertical direction. The through-hole 20 is a drainage hole for overflow and communicates with the lower side of the drainage pan 1. In addition, it is good also as a structure in which the through-hole 20 is not formed.

(Function)
Means for mounting the drainage pan 1 of the present invention having the above configuration to the drain outlet 8 and the operation of the drain pan 1 will be described below with reference to FIGS. A drainage case 21 is attached to the drainage port 8, and the drainage pan 1 is attached to the drainage case 21. Specifically, it is as follows.

  As shown in FIG. 3A, the shelf 25 formed in the drainage port 8 is sandwiched between the flange 22 of the drainage case 21 and the flange 23 of the adapter 9 via a seal 24. Then, the screw 26 formed on the outer peripheral surface of the adapter 9 is screwed onto the screw 26 formed on the inner peripheral surface of the drain case 21 from above, and the shelf portion 25 is tightened so that the adapter 9 is drained. 21 is fastened to the flange 22. Thereby, the drainage case 21 is installed in the drain outlet 8. In the drain case 21, a drain cylinder 31 having an open lower end is mounted such that the upper end flange 37 is hooked on the lower end flange 28 of the adapter 9 via a seal 27.

  Then, as shown in FIG. 3 (b), the curved protruding edge 7 formed on the outer surface of the drainage pan 1 is horizontally rotated in the receiving groove 29 formed in the circumferential direction on the inner surface of the adapter 9. In this manner, the drainage pan 1 is attached to the adapter 9. Thereby, the drainage pan 1 can be attached to the drainage case 21.

  As shown in FIG. 3 (b), the waste water that has flowed into the drain outlet 8 from the periphery of the drain lid 30 flows into the drain pan 1 from the flange portion 2 and is guided by the upper peripheral wall 6 to the surface of the upper step portion 10. It flows as a swirl flow along. Further, the waste water flows down from the upper stage portion 10 to the lower stage portion 11, passes through the plurality of drain holes 11 ′, and is discharged into the drain cylinder 31. Then, the drainage flows from the lower side of the drainage cylinder 31 to the outside beyond the weir 32 of the drainage case 21 and is discharged from the discharge pipe 33 to the 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 11 ′ of the lower part 11 is collected by the lower part 11. Then, when cleaning the drainage pan 1, the drainage pan 1 may be removed from the adapter 9 to remove the dust collected in the lower portion 11 or the like.

  The operation of the drainage pan 1 of the present invention will be described in more detail with reference to FIGS. FIG. 4A is a view showing a state in which the hair 34 that has flowed simultaneously with the drainage in the drainage pan 1 is guided to the lower stage 11. As shown by the white arrow in FIG. 4A, the waste water that has flowed into the drain pan 1 flows down into the lower step portion 11 while swirling along the upper peripheral wall 6 on the upper step portion 10.

  When the hair 34 is swirling along the upper peripheral wall 6 along with the drainage along the upper peripheral portion 10, the swirling force and buoyancy of the drainage acts on the hair 34 so that the hair 34 adheres to the upper step 10. It is flushed with drainage while floating. The hair 34 is guided to the lower stage 11 and collected.

  Therefore, even when the amount of drainage is relatively small, in the drainage pan 1, dust such as hair is difficult to adhere to the surface of the upper stage portion 10 and enters the drainage hole 10 ′ of the upper stage portion 10 and becomes clogged. This is less likely to occur, and more dust is easily collected in the lower stage portion 11 to be collected. Since the dust can be removed from the lower stage portion in a lump, it is easy to clean.

  The drainage pan 1 of the present invention is formed so as to stand up from the position (near the inner edge of the flange 2) where the handle 4 is retracted inside the outer edge of the flange 2. By providing the convex portion 16 integrated with the portion 15 upright on the upper step portion 10, the following action is produced.

  Garbage such as hair is likely to get entangled with the upright handle part. In particular, as shown in the prior art, when the outer surface of the handle part 55 is formed near the outer edge of the flange part 51, the handle part 55. Since the waste water flowing from the back side of the water is dammed just above the gap 35 between the flange portion 2 and the adapter 9 and the staying water 56 is generated, the hair 34 flows into the gap 35 together with the waste water and becomes clogged or tangled. Easy to do. (See FIG. 7 (c)).

  However, since the handle portion 4 of the drainage pan 1 of the present invention is erected at a position retracted inward from the outer edge of the flange portion 2, the drainage flowing from the back side of the handle portion 4 is shown in FIG. As described above, the accumulated water 36 is generated at a position where it flows further into the inner side than the gap 35 between the flange portion 2 of the drain pan and the adapter 9. In this staying drainage, the hair 34 that has flowed along with the drainage floats, and as shown in FIGS. 4B and 5A, the drainage flows from the back side of the convex portion 16 to the side of the side wall 17. It moves together as it flows toward the upper stage 10 while turning around.

  At this time, as described below, waste water staying near the left and right side walls 17 of the convex portion 16 is added, and the hair 34 moves more fluidly toward the upper step portion 10 and the lower step portion 11. Accordingly, the hair 34 is less likely to get into the gap 35 between the flange portion 2 and the adapter 9 and get entangled with the handle portion 4 or to adhere to the handle portion 4.

  That is, since the inner surface side of the handle portion 4 forms a convex portion 16 rising from the upper step portion 10 to a position higher than the flange portion 2, as shown in FIG. 4 (b), from the back side of the handle portion 4. In addition to the drainage that has flowed, drainage that has flowed from the side toward the side wall 17 of the handle portion 4 is added, and the amount of water increases and stays near the side wall 17. Therefore, the hair 34 that has flowed from the back side or the side of the handle portion 4 together with the drainage flows into the drainage accumulated on the upper step portion 10 near the side wall 17 and is further guided into the lower step portion 11. As a result, it becomes difficult for the hair 34 to be entangled or attached to the handle portion 4.

  Further, since the convex portion 16 is formed to a position higher than the flange portion 2, the hair 34 that has flowed on the flange portion 2 becomes difficult to ride on the top wall 19 of the convex portion 16, and the surface of the top wall 19. Also difficult to adhere to. And in the drainage pan 1 of this invention, since the side wall 17 of the convex-shaped part 16 is formed substantially perpendicularly, the amount of water which retains on the side surface increases, and the hair 34 stagnating near the side wall 17 surface is drained. While floating and floating inside, it is possible to flow from the side of the side wall 17 onto the upper step portion 10 and further to the lower step portion 11.

  In addition, when the amount of drainage is large and the drainage is soaked beyond the top wall 19, the drainage overflows, passes through the through hole 20, and is discharged directly into the drain tube 31 in the drainage case 21. .

  As described above, in the drainage pan 1 of the present invention, the hair 34 that has flowed along with the drainage flows from the flange portion 2 into the lower step portion 11 while going around the upper step portion 10, and thus is less likely to get entangled with the upper step portion 10. In addition, the handle portion 4 is formed on the inner side of the outer edge of the flange portion 2, and the convex portion 16 is erected on the upper step portion 10 on the inner surface side of the handle portion 4, so that the hair 34 is entangled with the handle portion 4. It becomes difficult. Accordingly, dust such as hair 34 is easily collected in the lower portion 11, so that dust can be easily removed at a time when the drainage pan 1 is cleaned.

  6 (a) and 6 (b) are diagrams illustrating Example 2 of the drainage pan according to the present invention. This Example 2 has substantially the same configuration as Example 1, but differs in the configuration of the lower peripheral wall of the drainage pan. Hereinafter, Example 2 is demonstrated centering on the structure of the lower surrounding wall different from Example 1, and the code | symbol same as the structure of Example 1 is made the same, and description of the structure is abbreviate | omitted.

  In the said Example 1, the drainage hole is not formed in the lower surrounding wall 12 of the drainage pan 1 as shown to Fig.1 (a) and FIG. However, in the second embodiment, a plurality of rectangular drain holes 38 are formed at intervals in the circumferential direction at the upper portion of the lower peripheral wall 12 ′ of the drain pan 1 ′. The drain hole 38 is a rectangular hole (square hole) in the second embodiment, but may be a round hole (round hole).

  And the hole-less part 39 is formed in the lower half of the lower peripheral wall 12 'of the drainage pan 1'. In short, a plurality of drainage holes 38 are formed in the lower peripheral wall 12 ′, and a holeless portion 39 is formed in a part thereof.

  In the second embodiment, as described above, since the plurality of drain holes 38 are provided in the lower peripheral wall 12 ′ of the drain pan 1 ′, a large drainage amount can be ensured as compared with a configuration in which no drain holes are provided. Therefore, even when the amount of water drained from the drain port 8 is large, it is possible to cope with it sufficiently. Moreover, since a holeless portion 39 is formed in the lower half of the lower peripheral wall 12 ′ of the drainage pan 1 ′, dust such as hair is less likely to stick to the vicinity of the lower step portion 4 of the lower peripheral wall 12 ′. In the lower stage part 11, it becomes easy to collect more collectively.

  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.
