马达模块以及吸尘器
摘要：
本发明提供一种马达模块以及吸尘器。该马达模块具有马达、风扇以及在内部容纳马达和风扇的壳体。壳体具有筒状的主体部、吸气口、排气口、马达配置部、流路以及分隔部。流路是在主体部与马达之间连接吸气口与排气口的空间。分隔部在流路的内部对流路进行分隔。流路包含：风扇容纳部；经第一连通路与风扇容纳部连通的第一消音室；以及经第二连通路与第一消音室连通的第二消音室。第一消音室的流路截面积比第一连通路的流路截面积大。第二消音室的流路截面积比第二连通路的流路截面积大。并且，分隔部包含对马达配置部与第一消音室进行分隔的第一内侧分隔部。第一消音室经设置于第一内侧分隔部的缺口部与马达配置部连通。
摘要（英）：

The invention provides a motor module and a vacuum cleaner. A motor module includes a motor, a fan, and a casing accommodating the motor and the fan therein. The casing includes a tubular main body portion, an intake port, an exhaust port, a motor disposing unit, a flow passage, and a partition unit. The flow passage includes a fan accommodating unit, a first muffling chamber that communicates with the fan accommodating unit via a first communication path, and a second muffling chamber that communicates with the first muffling chamber via a second communication path. The cross-sectional area of the flow path of the first muffler chamber is larger than the cross-sectional area of the flow path of the first communication path. The cross-sectional area of the flow path of the second muffler chamber is larger than the cross-sectional area of the flow path of the second communication path. In addition, the partition unit includes an inner partition unit that partitions the motor disposingunit and the first muffling chamber. The first muffling chamber communicates with the motor disposing unit via a cutout portion in the inner partition unit.
