Moreover, the drainage resistance part 42 may not be provided in the draining part 1 .

The water storage part 2 has a bottom part 20, a drain hole 21 and a side part 22, and is formed in a bowl shape. The water reservoir 2 may be formed, for example, in the shape of a dish or a deep dish, and may have various shapes such as a cylindrical shape, a truncated cone shape, or a hemispherical shape as a whole. The drain hole 21 is provided in the lower end portion of the side surface portion 22 of the water storage portion 2 so as to penetrate the inside and outside in the lateral direction.

The vertical wall portion 5 is formed in an arc along the upper edge portion 10 so as to rise from the upper edge portion 10, and is composed of two rotationally symmetrical first and second vertical wall portions 50 and 55. As shown in FIG. The introduction end portion 51 of the first standing wall portion 50 and the terminal end portion 57 of the second standing wall portion face each other with a space therebetween, and a water conduit from the floor 8 of the washing space is formed therebetween. Similarly, the introduction end portion 56 of the second standing wall portion 55 and the terminal end portion 52 of the first standing wall portion face each other with a gap therebetween, and a water conduit from the washing space floor 8 is formed therebetween.

The introduction ends 51 and 56 of the vertical wall portion 5 are provided so as to extend inside the draining portion 1 . The introduction ends 51 and 56 are inclined so as to extend to one side in the circumferential direction as they go downward in the draining section 1 . The introduction ends 51 and 56 are inclined so as to extend clockwise when viewed from above as they go downward of the draining section 1 . Leading ends 51 and 56 are provided inside hair catcher 100 relative to terminal ends 57 and 52 . For example, the center side of the hair catcher 100 in plan view shown in FIG. 3 is defined as the inner side, and the side away from the center in the radial direction is defined as the outer side.

A water guiding surface 6 extending from the upper edge portion 10 to the water storage portion 2 is formed between the introduction end portion 51 and the terminal end portion 57 of the standing wall portion 5 . Similarly, a water guiding surface 6 extending from the upper edge portion 10 to the water storage portion 2 is formed between the introduction end portion 56 and the terminal end portion 52 . The water conveying surface 6 is inclined so as to extend to one side in the circumferential direction as it goes downward. As with the introduction ends 51 and 56 , the water guiding surface 6 is inclined so as to extend clockwise when viewed from above as it goes downward in the draining section 1 . Incidentally, in the drainage part 1 shown in FIG. 3, the flow holes 4 are not provided in the water guide surface 6, but the flow holes 4 may be provided sparsely.

Please refer to FIG. Direction A is the direction from the center of the upper edge 10 of the hair catcher 100 to the center between the leading end 51 and the terminal end 57 of the standing wall portion 5 . Although the introduction end portion 51 and the terminal end portion 57 will be described below for the sake of brevity, the introduction end portion 56 and the terminal end portion 52 of the standing wall portion 5 are also formed in the same manner as the introduction end portion 51 and the terminal end portion 57 .

The introduction end portion 51 moves away from the terminal end portion 57 when viewed in the circumferential direction from the rising position 51a (position on the inner surface of the draining portion 1), which is the farthest position inside the draining portion 1, It is formed so that the height of the wall gradually increases. At the introduction end 51, the vertical wall portion 5 decreases in height toward the rising position 51a. The upper side 51b of the lead-in end portion 51 shown in FIG. 4 is convexly curved upward, and has a steep slope on the side of the raised position 51a, which gradually becomes gentler as the distance from the raised position 51a increases. It is formed to have a slope.

A side 57 a of the terminal end 57 extends perpendicularly to the upper edge 10 . As described above, at the introduction end portion 51, the height of the standing wall portion 5 decreases toward the raised position 51a. The height is constant up to the side edge 57a. A corner portion where the side edge 57a and the upper edge 57b intersect is appropriately chamfered, but the height including the corner portion is considered to be constant.

In addition, as shown in FIG. 4, the introduction end portion 51 and the terminal end portion 57 are spaced apart by a distance L in the circumferential direction. Although the introduction end portion 51 and the terminal end portion 57 can be provided so as to approach or overlap each other as viewed in arrow A, water is less likely to flow into the draining portion 1 compared to the case where they are spaced apart.

Next, operation of the hair catcher 100 according to the embodiment will be described. The water that has flowed from the upper edge 10 of the hair catcher 100 to the upper portion of the draining portion 1 flows down the inside of the hair catcher 100 along the water guide surface 6 to generate a swirling flow as indicated by the arrows in FIG. A portion of the water flowing down inside the draining portion 1 is drained outside the draining portion 1 through the flow holes 4 as indicated by the arrow Q1 in FIG. The water flowing down the inside of the draining portion 1 is restricted by the drainage resistance portion 42 provided in the flow hole 4, so that it stays inside the draining portion 1 as indicated by the arrow Q2 and flows down. Swirling flow is more likely to occur.

The drainage resistance part 42 is formed so as to protrude toward the center of the flow hole 4 in the circumferential direction on the side of the edge 41a of the vertical rib 31 at the end of the direction in which the water flows in the opening 41 of the flow hole 4. is provided. For this reason, the water flowing down the inside of the draining portion 1 hits the drainage resistance portion 42 and is easily returned to the inside of the draining portion 1 .

In the hair catcher 100, a swirling flow is generated inside the draining portion 1, so that the hair or the like is collected in the water storage portion 2, which facilitates cleaning. A drain hole 21 is provided in the water reservoir 2 . When a swirling flow occurs, a part of the water is discharged from the drain hole 21, but the water is accumulated in the water storage part 2, and after the water stops flowing, the water accumulated in the water storage part 2 is drained over time. 21 is drained.

The vertical wall portion 5 introduces water from the washing floor 8 into the draining portion 1 through the introduction path between the introduction end 51 and the terminal end 57 and the introduction path between the introduction end 56 and the terminal end 52. do. The introduction ends 51 and 56 are inclined so as to extend clockwise when viewed from above as they go downward along the inner surface of the draining portion 1, thereby promoting the generation of a clockwise swirling flow. .

Please refer to FIG. As indicated by arrows in FIG. 5 , on the introduction end portion 51 side of the standing wall portion 5 , water flows clockwise when viewed from above and flows into the water guiding surface 6 . Also, on the terminal end portion 57 side, the water likewise flows clockwise when viewed from above and is guided to the introduction end portion 56 of the second standing wall portion 55 . A swirling flow is generated inside the draining portion 1 by the water flowing in along the introduction end portion 51 .

Please refer to FIG. FIG. 6 corresponds to the arrow view shown in FIG. Since the side 57a of the terminal portion 57 is provided perpendicular to the upper edge portion 10, it is difficult for water to flow into the water guide surface 6 from the terminal portion 57 side, so that it is difficult to prevent the occurrence of a swirling flow. In addition, since the introduction end portion 51 and the terminal end portion 57 are spaced apart in the circumferential direction, water can easily flow into the inside of the hair catcher 100 .

When the amount of water flowing from the outside increases, there is a possibility that the water will flow over the standing wall portion 5 and flow into the draining portion 1. - 特許庁However, since the upper side 51b of the introduction end 51 is formed to gradually increase in height from the raised position 51a, the introduction end 51 can be positioned at a lower position as indicated by an arrow P1 in FIG. Water flows into the draining part 1 over the standing wall part 5. - 特許庁The lower the position at which the water passes over the vertical wall portion 5, the smaller the potential energy of the water, and the less the influence of disturbing the swirl flow generated in the draining portion 1 is.

When the amount of water flowing in from the outside increases, the water flows over the vertical wall portion 5 at a low height at the introduction end portion 51 as described above, thereby increasing the flow rate at the introduction end portion 51 and increasing the flow rate at the introduction end portion 51 as indicated by the arrow P2 shown in FIG. Thus, it is possible to prevent water from getting over the vertical wall portion 5 other than the introduction end portion 51 . By suppressing the overriding of water on the standing wall portion 5 other than the introduction end portion 51, it is possible to suppress the influence of the water flowing in from a high position on the swirling flow.

(Modification)
Please refer to FIGS. 7(a) and 7(b). 7(a) and 7(b) correspond to the arrow view shown in FIG. The introduction end portion 51 shown in FIG. 7A has an upper side 51b formed in a tapered shape, and the inclination of the upper side 51b is constant. In this case as well, the height of the standing wall portion 5 at the introduction end portion 51 is reduced, so that the effect of disturbing the swirling flow generated inside the draining portion 1 is reduced.

The lead-in end portion 51 shown in FIG. 7B includes an upper side portion 51c that curves upward from the raised position 51a, and an upper side portion 51d that is continuous with the upper side portion 51c and curves concavely upward. have In this case, since the introduction end portion 51 can be given a certain height by providing the upper side portion 51c, even if the amount of water flowing in from the outside increases, the amount of water at the introduction end portion 51 will not exceed a certain amount. can be suppressed. In addition, since the upper side portion 51d is concave upward, the height of the vertical wall portion 5 is formed low. By providing the upper side portion 51d, when the amount of water flowing in from the outside exceeds a certain amount or more, the flow of water over the upper side portion 51d of the introduction end portion 51, which has little effect on the swirling flow, is promoted. Therefore, it is possible to prevent water from getting over the standing wall portion 5 other than the introduction end portion 51 . Note that the introduction end portion 56 of the standing wall portion 5 can also be configured in the same manner as the introduction end portion 51 according to the modified example.

In the above-described embodiment and modified example, an example in which the swirling flow is generated clockwise when viewed from above is shown, but the configuration may be such that the swirling flow is generated counterclockwise when viewed from above. Further, even if the water guiding surface 6 is not provided, the leading end portions 51 and 56 and the terminal end portions 52 and 57 of the standing wall portion 5 have the effect of disturbing the swirl flow due to the water running over them, as in the embodiment and the modified example. Inflow of water from the ends 52 and 57 can be reduced.

Next, the features of the hair catcher 100 of the embodiment and modifications will be described.
The hair catcher 100 of each of the embodiments and modifications of the present invention includes a vertical wall 5 that rises from the upper edge 10 through which water flows and is formed along the upper edge 10 . The vertical wall portion 5 is provided with an introduction end portion 51 as one end portion and a terminal end portion 57 as the other end portion with a space therebetween. The lead-in end portion 51 is formed inside the terminal end portion 57, and is formed so that the height gradually increases in the direction away from the terminal end portion 57 when viewed in the circumferential direction from the raised position 51a on the inner side. ing. Thus, the hair catcher 100 can prevent water from running over the standing wall portion 5 .

A side edge 57 a of the terminal end portion 57 is formed perpendicular to the upper edge portion 10 . As a result, the hair catcher 100 makes it difficult for water to flow into the water guide surface 6 from the end portion 57 side, so that it is difficult to prevent the occurrence of a swirling flow.

In addition, the introduction end portion 51 and the terminal end portion 57 are spaced apart in the circumferential direction. This makes it easier for water to flow into the hair catcher 100 .

The above has been described based on the embodiments of the present invention. Those skilled in the art will appreciate that these embodiments are illustrative and that various variations and modifications are possible within the scope of the claims of the present invention, and that such variations and modifications also fall within the scope of the claims of the present invention.
