JP 2009-7784 A

  7 (a) and 7 (b), for example, when the amount of drainage is large and the momentum of the flow is strong, most of the drainage flows to the bottom 45, which is the center of the drainage plate 40. Since the waste water is discharged through the drainage hole 44, dust such as hair flowing simultaneously with the drainage is guided to the bottom 45 and collected.

  However, when the amount of drainage is small, a large amount of drainage is also discharged from the mesh drainage holes 41 of the flange portion 42, so that dust such as hair that flows at the same time becomes difficult to be guided to the bottom portion 45. There is a problem in that it is caught by the inclined wall surface 43 and attached, and it becomes difficult to collect and collect dust on the bottom 45, and cleaning the drain pan 40 is troublesome.

  In the present invention, even when the amount of drainage is small, dust such as hair flowing simultaneously with the drainage is collected and collected as much as possible in the bottom part (lower part in the present invention) that is the center of the drainage pan. It is an object of the present invention to achieve a structure that facilitates cleaning and a drainage pan that is easy to handle by removing collected waste from the bottom at the time of cleaning the drain pan.

In order to solve the above-mentioned problems, the present invention provides a drainage pan having a collection part for collecting garbage, and a plurality of upper and lower stage parts having drainage holes through which a part of the drainage flows are concentric. to comprise, Bei give a flat portion to further upper than the upper portion, the upper portion and the lower portion are connected by the rising portion, and no hole is formed in a part of the rising portion, no hole is lower portions The flat part and the upper part are formed in an annular shape, and the lower part is located in the center of the drainage pan, and concentric annular ribs are formed on the upper surface thereof. Provide a drain pan.

It is preferable that the drain hole of the lower step part is formed between the annular ribs adjacent to each other .

  Since the drainage pan of the present invention is provided with an upper step as an intermediate step between the flat portion and the lower step of the collection portion, even when the amount of drainage is small, due to the momentum and buoyancy of the drainage flow, Since dust such as hair flows down to the lower part and accumulates and is collected, the collected garbage can be easily removed from the lower part at a time, and cleaning becomes easy.

  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.

  1-4 is a figure explaining Example 1 of the draining-eye plate which concerns on this invention. The drainage pan 1 according to the present invention has an annular flat surface portion 2, an upper step portion 3 and a lower step portion 4, and is generally formed in a dish shape as shown in FIGS.

  In the first embodiment, the flat portion 2 is formed as an annular flange having a flat surface extending horizontally in the radial direction in the drainage pan 1, and is attached to a drain outlet 5 such as a bathroom in a bathroom. (See FIG. 3B). The plane portion 2 corresponds to the flange portion 42 of the conventional drain pan 1 shown in FIG. 7, but in particular, drain holes (see the mesh drain holes 41 in FIG. 7) are not formed, and drainage is performed on the upper stage 3. It will be a part to be introduced. A handle portion 6 is erected and integrally provided on the flat surface portion 2 of the drainage pan 1.

  As shown in FIG. 2B, the flat surface portion 2 is continuous with the annular upper peripheral wall 8 via a bent portion 7 bent downward at the inner peripheral edge thereof. The upper peripheral wall 8 is formed of a vertical surface or an inclined surface. A protruding edge 9 is formed on the outer surface of the upper peripheral wall 8 in a curved shape along the outer surface. As will be described later, the protruding edge 9 is fitted to the adapter 10 when attached to the drain port 5.

  The present inventor reduces the friction between the drainage and the bent portion 7 by reducing the contact area with the bent portion 7 of the drainage that flows downward from the plane portion 2 in the trial process of the drainage pan 1 in the development of the present invention. It can be made small so that the flow velocity of the drainage does not slow down. For this reason, it has been found that the radius of curvature of the bent portion 7 is preferably 5 mm or less.

  It is bent horizontally from the lower end of the upper peripheral wall 8 and continues to the upper stage portion 3. The upper step portion 3 is a so-called intermediate step portion located at a height between the flat portion 2 that is the uppermost portion and the lower step portion 4 (bottom portion) that is the lowermost portion in the drainage pan 1. The structure provided with such an intermediate step is the main feature of the present invention. The upper stage portion 3 is provided with a plurality of drain holes 11 so that a part of the drainage flowing along the upper stage portion 3 can pass therethrough. In the first embodiment, only one stage is provided for the upper stage 3 (intermediate stage), but a plurality of stages may be provided.

  By the way, when the height difference between the flat portion 2 and the upper step portion 3, that is, the height of the annular upper peripheral wall 8, is large, the amount of drainage is small, and the hair that has flowed simultaneously with the drainage when the flow rate of the drainage is weakened. Or the like will adhere to the inner surface of the upper peripheral wall 8 and will not easily flow down. Therefore, as a result of various trial manufactures of the drainage pan 1, the inventor hardly adheres to the inner surface of the upper peripheral wall 8, and makes it easy to flow along with drainage to the lower upper stage 3. It has been found that it is preferable to make the height difference within 10 mm.

  The upper step portion 3 is formed downward from the inner peripheral edge thereof, continues to a rising portion (hereinafter referred to as “lower peripheral wall”) 12, and further, the lower end of the lower peripheral wall 12 is formed horizontally, and the lower step portion 4 It is continuous. The lower peripheral wall 12 is formed by a vertical surface or an inclined surface, and no drain hole is formed.

  The lower part 4 is a part corresponding to the bottom part of the drainage pan 1, and has a plurality of drainage holes 13. The lower part 4 passes through the drainage holes 13 to discharge the drainage and has a function of collecting dust. . A plurality of annular ribs 14 are formed on the upper surface of the lower step portion 4 so as to be concentrically convex upward, and the plurality of drain holes 13 are spaced circumferentially 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 4, facilitating removal of the dust when the drain pan 1 is cleaned, and improving the strength of the lower step portion 4.

(Function)
A configuration for mounting the drainage pan 1 having the above configuration to the drain outlet 5 and an operation of the drainage pan 1 will be described below with reference to FIGS. 3 and 4. A drainage case 15 is attached to the drainage port 5, and the drainage pan 1 is attached to the drainage case 15. Specifically, it is as follows.

  As shown in FIG. 3A, the shelf 19 formed in the drainage port 5 is sandwiched between the flange 16 of the drainage case 15 and the flange 17 of the adapter 10 via a seal 18. Then, the screw 21 formed on the outer peripheral surface of the adapter 10 is screwed into the screw 20 formed on the inner peripheral surface of the drainage case 15 from above, and the shelf portion 19 is tightened so that the adapter 10 is connected to the drainage case 15. The flange 16 is fastened. Thereby, the drainage case 15 is installed in the drain outlet 5. In the drain case 15, a drain tube 22 having an open lower end is attached by hooking an upper end portion of the drain tube 22 to a lower end flange 24 of the adapter 10 via a seal 23.

  Then, as shown in FIG. 3 (b), the curved protruding edge 9 formed on the outer surface of the drainage pan 1 is horizontally rotated in the receiving groove 25 provided in the circumferential direction on the inner surface of the adapter 10. In this manner, the battery is inserted and attached to the drainage pan 1 adapter 10. Accordingly, the drainage pan 1 can be attached to the drainage case 15.

  As shown in FIG. 3 (b), the waste water that has flowed into the drain outlet 5 from the periphery of the drain lid 26 flows along the flat portion 2 of the drainage pan 1, and is further guided by the upper peripheral wall 8 to the upper step portion 3. It flows as a swirling flow along the surface. Further, the waste water flows down from the upper stage portion 3 to the lower stage portion 4, passes through the plurality of drain holes 13, and is discharged into the drain cylinder 22. The drainage flows from the lower side of the drainage cylinder 22 to the outside beyond the weir 27 of the drainage case 15 and is discharged from the discharge pipe 28 to the drainage channel or the like.

  Dust that flows into the drainage pan 1 together with the drainage and cannot pass through the drainage holes 13 of the lower stage 4 is collected by the lower stage 4. Then, when cleaning the drain pan 1, the drain pan 1 may be removed from the adapter 10 to remove the dust collected in the lower portion 4.

  The effect | action by having provided the upper stage part 3 in the drainage pan 1 of this invention is demonstrated still in detail with FIG. 4 (a) to 4 (d) are diagrams sequentially showing the state in which the hair 29 that has flowed simultaneously with the drainage in the drainage pan 1 is guided to the lower stage 4. As shown by the white arrows in FIGS. 4A to 4D, the drainage that has flowed into the drainage pan 1 swirls along the upper peripheral wall 8 on the upper stage 3 while flowing downward, 4 flows down.

  FIG. 4A shows a state in which the hair 29 is approaching the flat surface portion 2 of the drainage pan 1, and the hair 29 extends along the upper peripheral wall 8 on the upper step portion 3 as shown in FIG. 4B. It flows with the drainage that turns and flows. Then, as shown in FIG. 4C, when the hair 29 is flowing on the upper stage portion 3, the momentum of the swirling flow and the buoyancy act on the hair 29 so that the hair 29 adheres to the upper stage portion 3. It is flushed with drainage while floating. And as shown in FIG.4 (d), the hair 29 is guide | induced to the lower stage part 4 and is collected.

  As described above, the drainage pan 1 of the present invention is provided with the upper stage portion 3 below the flat surface portion 2 formed as the uppermost annular flange. It becomes easy to flow as a swirl flow, and it flows to the lower stage 4 while flowing the swirl flow and the buoyancy of the drainage against dust such as hair. As a result, in the drainage pan 1, dust such as hair is less likely to adhere to the surface of the upper stage portion 3, and it is difficult to cause clogging by entering the drainage holes 11 of the upper stage portion 3.

  Accordingly, compared to the conventional drainage pan 40 having the flange portion 42 and the bottom 45 as shown in FIG. 7, according to the drainage pan 1 of the present invention, dust such as hair flows along the drainage pan 1. In the middle, the amount of sticking to or catching on the upper stage 3 of the drainage pan 1 is reduced, and more is easily collected in the lower stage 4 to be collected.

  And if the curvature radius of the bending part 7 of the drainage pan 1 is 5 mm or less, since the contact area with the surface of the bending part 7 of the drainage which flows down from the plane part 2 becomes small, the drainage and the bending part 7 Friction is reduced, and the flow rate of drained water is relatively low. As a result, it becomes difficult for dust to adhere to the upper step portion 3, the upper peripheral wall 8, the lower peripheral wall 12, etc., and can be effectively guided by flowing to the lower step portion 4.

  Further, if the height difference between the flat portion 2 and the upper step portion 3 is within 10 mm, the time for dust such as hair to flow down the vicinity of the upper peripheral wall 8 is shortened, so that the flat portion 2 is less likely to adhere to the upper peripheral wall 8. It becomes easy to flow with drainage from the upper part 3 to the lower part.

  Furthermore, if the ribs 14 are formed on the surface of the lower step portion 4, dust such as hair collected on the lower step portion 4 is in direct contact with the surface of the lower step portion 4 and is less likely to adhere. Also during cleaning, dust can be easily removed, and the strength of the lower portion 4 is increased.

  5 (a) and 5 (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 in FIG.1 and FIG.2 (b). However, in the second embodiment, a plurality of rectangular drain holes 12'-1 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 12'-1 is a rectangular hole (square hole) in the second embodiment, but may be a round hole (round hole).

  A holeless portion 12'-2 is formed in a substantially lower half of the lower peripheral wall 12 'of the drainage pan 1'. In short, a plurality of drain holes 12'-1 are formed in the lower peripheral wall 12 ', and a holeless portion 12'-2 is formed in a part thereof.

  In the second embodiment, as described above, since the plurality of drain holes 12'-1 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 5 is large, it is possible to cope with it sufficiently. Moreover, since a holeless portion 12′-2 is formed in the lower half of the lower peripheral wall 12 ′ of the drainage pan 1 ′, dust such as hair is present near the lower step portion 4 of the lower peripheral wall 12 ′. It becomes difficult to stick, and it becomes easier to collect in the lower stage 4 more collectively.

  6 (a) to 6 (c) are diagrams for explaining Example 3 of the drainage pan according to the present invention. The third embodiment has substantially the same configuration as that of the first embodiment, but is partially different in the configuration of the handle portion. Hereinafter, the third embodiment will be described with a focus on the configuration of the handle portion different from the first embodiment.

  In the drain pan 30 of the third embodiment, the handle portion 31 is characterized in that a deflecting portion 32 is integrally formed at a lower portion thereof. The deflecting portion 32 is formed in a table shape so as to protrude on the upper stage portion 3 toward the center of the drainage pan 30. The deflection unit 32 includes left and right side walls 33, a front wall 34, and a top wall 35, and the inside is formed in a cavity as shown in a sectional view in FIG. A through hole 36 is formed through the top wall 35 in the vertical direction, and the through hole 36 communicates below the drainage pan 1.

  The operation of the drain pan 30 of the third embodiment is substantially the same as that of the first embodiment, but the following operation is generated by the deflecting unit 32. That is, the waste water that flows while turning around the upper stage portion 3 is deflected toward the center of the drainage pan 1 by the side wall 33 of the deflection unit 32 and flows into the lower stage portion 4. As a result, it is possible to guide the dust such as hair flowing simultaneously with the drainage more positively by deflecting the lower portion 4.

  In addition, when the amount of drainage is large and the drainage is soaked further upwards beyond the top wall 35, the drainage overflows and passes through the through hole 36 and directly into the drainage cylinder in the drainage case (not shown here, (See FIG. 3 of Example 1). A drain hole similar to that in the second embodiment may be provided in the lower peripheral wall.

  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.
