HAIR CATCHER

To provide a hair catcher that efficiently traps trash by generating a vortex.SOLUTION: Each vortex generation part 2 comprises: an arc-shaped outer surface part 2a that gently rises inward from an outer edge part 1; and an inner surface part 2b that is located inside the arc-shaped outer surface part. Further, a portion that continues from the inner surface part 2b and reaches the outer surface part 2a of an adjacent vortex generation part 2 is a slope part 2d. A water retaining part 3 located below the vortex generation part 2 and an annular part 4 has a bowl-shaped bottom part 3a, and a plurality of bottom drainage holes 3b are provided in a lower part of the bowl-shaped bottom part. A plurality of intermediate drainage holes 4b are bored in the annular part 4. Waste water W flowing along the outer surface part 2a of the vortex generation part 2 flows in an arc shape on the slope part 2d between the outer surface part and the inner surface part 2b of an adjacent vortex generation part 2 as shown by an arrow, and becomes a vortex. Garbage D in the waste water W flowing into the water retaining part 3 is captured at the center, and the waste water W flows out from the bottom drainage holes 3b, and when the water retaining part 3 overflows, the waste water W is also drained from the intermediate drainage hole 4b.SELECTED DRAWING: Figure 4 【課題】渦流を発生させて、ごみを効率良く捕捉する。【解決手段】各渦流生成部２は、外縁部１から内側に向き緩やかに立ち上がる円弧状の外面部２ａと、その内側に位置する内面部２ｂとを有している。また、内面部２ｂに連続し、隣接する渦流生成部２の外面部２ａに至る個所は斜面部２ｄとされている。渦流生成部２、円環部４の下方に位置する保水部３は椀状の底面部３ａを有し、その下部には複数個の底部排水孔３ｂが設けられている。円環部４には、複数個の中間排水孔４ｂが穿孔されている。渦流生成部２の外面部２ａに沿って流れる排水Ｗは、隣接する渦流生成部２の内面部２ｂとの間の斜面部２ｄ上を矢印に示すように円弧状に流れ込み渦流となる。保水部３内に流入した排水Ｗのうち、ごみＤは中央で捕捉され、排水Ｗは底部排水孔３ｂから流出し、保水部３がオーバーフローすると、中間排水孔４ｂからも排水される。【選択図】図４
