Title (EN) DUST COLLECTION DEVICE AND AIR CONDITIONER
(FR) DISPOSITIF DE COLLECTE DE POUSSIÈRE ET CLIMATISEUR
(JA) 集塵デバイスおよび空気調和機
Abstract:
(EN) A dust collection device (1) is provided with: a plurality of dust collection bodies (2) that are charged by friction and arranged with spaces therebetween such that air ducts (20) for passage of air are formed; and one or more friction bodies (3) for applying friction to and charging the dust collection bodies. At least one of the dust collection bodies facing each other across an air duct has one or more protruding parts (21) protruding into the air duct. With this dust collection device, it is possible to improve particle collection efficiency in a friction charged dust collection device by forming a nonuniform electric field surrounding a charging body so as to induce gradient force.
(FR) La présente invention concerne un dispositif de collecte de poussière (1) comprenant : une pluralité de corps de collecte de poussière (2) qui sont chargés par frottement et agencés avec des espaces entre eux de telle sorte que des conduits d'air (20) pour le passage de l'air sont formés ; et un ou plusieurs corps de frottement (3) pour appliquer un frottement aux corps de collecte de poussière et les charger. Au moins un des corps de collecte de poussière se faisant face à travers un conduit d'air comporte une ou plusieurs parties saillantes (21) faisant saillie dans le conduit d'air. Le présent dispositif de collecte de poussière permet d'améliorer l'efficacité de collecte de particules dans un dispositif de collecte de poussière chargé par frottement par formation d'un champ électrique non uniforme entourant un corps de charge de façon à induire une force de gradient.
(JA) 集塵デバイス(1)は、空気が通過する風路(20)が形成されるように互いに間隔をあけて配列された、摩擦により帯電する複数の集塵体(2)と、集塵体を摩擦して帯電させる1以上の摩擦体(3)と、を備え、風路を挟んで対向する集塵体のうち少なくとも一方は、風路に向かって突出する1以上の突起部(21)を有する。本発明の集塵デバイスによれば、摩擦帯電式の集塵デバイスにおいて、帯電体の周囲に不平等電界を形成してグラディエント力を誘起し、粒子捕集率を向上することができる。
