Title
(EN) CYCLONE SEPARATION DEVICE AND ELECTRIC VACUUM CLEANER USING SAME
(FR) DISPOSITIF DE SÉPARATION À CYCLONE ET ASPIRATEUR ÉLECTRIQUE L’UTILISANT
(JA) サイクロン分離装置及びこれを用いた電気掃除機
Abstract
(EN) This invention is provided with: an inlet (212) into which dust-containing air from an external air path flows; a swirl chamber (218), formed so as to have a substantially cylindrical shape, for swirling the dust-containing air which has flowed in from the inlet (212) and separating air and dust from each other; an outside-side-wall dust-collecting chamber (235) for collecting dust separated from the dust-containing air via a side wall opening (213) opening in a side wall (211a) of an upper cylindrical part (211) of the swirl chamber (218); and a discharge port (244) for discharging air separated from the dust-containing air in the swirl chamber. A rib (220) for suppressing the wind noise of the airflow passing through the side wall opening (213) is provided to the side wall opening (213).
(FR) L'invention comprend : une entrée (212) dans laquelle pénètre de l'air contenant de la poussière provenant d'un écoulement d'air extérieur ; une chambre de turbulence (218), conçue de façon à présenter une forme essentiellement cylindrique, pour faire tourbillonner l'air contenant de la poussière qui s'est écoulé depuis l'entrée (212) et séparer l'air et la poussière l'un de l'autre ; une chambre de collecte de poussière de paroi latérale extérieure (235) collectant la poussière séparée de l'air contenant de la poussière par le biais d'une ouverture de paroi latérale (213) ménagée dans une paroi latérale (211a) d'une partie cylindrique supérieure (211) de la chambre de turbulence (218) ; et un orifice d'évacuation (244) par lequel est évacué l'air séparé de l'air contenant de la poussière dans la chambre de turbulence. L'ouverture de paroi latérale (213) est dotée d'une nervure (220) servant à supprimer le bruit de sifflement qui se produirait lorsque le flux d'air traverse l'ouverture de paroi latérale (213).
(JA) 外部風路からの含塵空気が流れ込む流入口(212)と、略円筒形状に形成され、流入口(212)から流れ込んだ含塵空気を旋回させて空気と塵埃とを分離する旋回室(218)と、旋回室(218)の上部円筒部(211)の側壁(211a)に開口する側壁開口部(213)を介して塵含空気から分離した塵埃を溜める側壁外集塵室(235)と、旋回室内の含塵空気から分離した空気を排出する排出口(244)とを備え、側壁開口部(213)に、側壁開口部(213)を通過する気流の風切音を抑制するリブ(220)を設けた。
