Title
(EN) FAN SYSTEM, RANGE HOOD USING FAN SYSTEM, AND MOUNTING METHOD FOR RANGE HOOD
(FR) SYSTÈME DE VENTILATEUR, HOTTE ASPIRANTE UTILISANT LE SYSTÈME DE VENTILATEUR, ET PROCÉDÉ DE MONTAGE POUR HOTTE ASPIRANTE
(ZH) 风机系统、应用有该风机系统的吸油烟机及其安装方法
Abstract
(EN) Disclosed is a fan system, comprising a volute casing (21), and an impeller (22) and an electric motor (23) arranged inside the volute casing (21), wherein the volute casing (21) comprises a front cover plate (211), a rear cover plate (212) and an annular wall (213); an air inlet (215) is formed on the front cover plate (211); the air inlet (215) faces downwards when the fan system is in a mounting state; the electric motor (23) comprises an electric motor body (231) and a skirt edge (233); and the skirt edge (233) is connected and fixed to the rear cover plate (212) by means of a side of the rear cover plate (212) facing the air inlet (215). Further disclosed are a range hood using the fan system, and a mounting method for a flow guiding device of the range hood. Compared with the prior art, the present invention allows the electric motor to be mounted from the air inlet, such that when the draught fan system is horizontally arranged, disassembly and assembly of the electric motor can be conveniently completed.
(FR) La présente divulgation concerne un système de ventilateur comprenant un carter de volute (21), et une roue (22) et un moteur électrique (23) disposés à l'intérieur du carter de volute (21), le carter de volute (21) comprenant une plaque de capot avant (211), une plaque de capot arrière (212) et une paroi annulaire (213) ; une entrée d'air (215) est formée sur la plaque de capot avant (211) ; l'entrée d'air (215) est orientée vers le bas lorsque le système de ventilateur est dans un état de montage ; le moteur électrique (23) comprend un corps de moteur électrique (231) et un bord de jupe (233) ; et le bord de jupe (233) est raccordé et fixé à la plaque de capot arrière (212) au moyen d'un côté de la plaque de capot arrière (212) faisant face à l'entrée d'air (215). Sont également divulgués une hotte aspirante utilisant le système de ventilateur et un procédé de montage pour un dispositif de guidage d'écoulement de la hotte aspirante. Par comparaison avec l'état de la technique, la présente invention permet au moteur électrique d'être monté à partir de l'entrée d'air, de telle sorte que, lorsque le système de ventilateur de tirage est disposé horizontalement, le démontage et le montage du moteur électrique peuvent être achevés de manière pratique.
(ZH) 本发明公开了一种风机系统,包括蜗壳(21)、设置在蜗壳(21)内的叶轮(22)和电机(23),蜗壳(21)包括前盖板(211)、后盖板(212)以及环壁(213),前盖板(211)上开设有进风口(215),风机系统安装状态下,进风口(215)朝下,电机包括电机本体(23)包括电机本体(231)和裙边(233),裙边(233)由后盖板(212)朝向进风口(215)的一侧与后盖板(212)连接固定。本发明还公开了一种应用有上述风机系统的吸油烟机,以及该吸油烟机的导流装置的安装方法。与现有技术相比,本发明将电机从进风口装入,当风机系统为卧式布置时,可方便地完成电机的拆装。
