VENTILATION STRUCTURE OF DRAINAGE HOPPER
To provide a ventilation structure of drainage hopper capable of easily preventing stagnation of drainage in an indirect drainage part.SOLUTION: The ventilation structure includes: a drainage hopper 4 that has a diameter reduction part 4a whose diameter decreases downward and a tubular upper edge portion 4b having the same diameter as the upper end of the reduced diameter portion above the reduced diameter portion 4a, which is configured to receive drainage from above; and a plurality of ventilation pipe parts 5 formed along the inner wall of the drainage hopper 4 so that its upper end is positioned above the upper edge of the reduced diameter portion upper end and its lower end is positioned below the reduced diameter portion 4b lower end. The position of the upper end of the ventilation pipe 5 is set to the position of the upper end of the upper edge 4b of the drainage hopper 4.SELECTED DRAWING: Figure 1
【課題】間接排水部における排水の停滞を簡便に防止し得る排水ホッパの通気構造を提供する。【解決手段】下方へ向かって径が小さくなる縮径部４ａと縮径部４ａの上部に縮径部上端と同径筒状の上縁部４ｂとを備え、上方からの排水を受けるよう構成された排水ホッパ４と、縮径部上部の上縁部上端より上に上端が、縮径部４ｂの下部から下に下端が位置するよう、排水ホッパ４の内壁に沿って設けられた通気管部５とを備える。通気管部５の上端部の位置は、排水ホッパ４の上縁部４ｂの上端の位置に設定する。【選択図】図１
