Abstract

The present invention relates to a silencer for reducing the noise emission of an air flow generator comprising a motor (2A) operating a blower (2B), such as an air flow generator in a vacuum cleaner, said silencer comprising a motor housing (1) that delimits a volume which extends at least radially around the air flow generator (2A, 2B), said housing (1) having a wall member extending in a generally axial direction and that is provided with at least one air inlet flow passage (4) and at least one air outlet flow passage (3), wherein at least one of said flow passages includes at least one folded elongated flow channel (3A, 3B) that is integrally formed in the wall member of the motor housing (1). By "folding" or bending the channel (3), a relatively long and compact channel is provided compared to the volume (V) of the housing. This allows for a compact design of the silencer by integrating it into the motor housing. This in turn means that a compact design of the appliance in which the silencer is to be used can be obtained; just as an efficient means of noise reduction is obtainable having the same or even a superior silencing effect compared to the silencers known in the art. Moreover, a relatively simple structure is obtained that is easy and inexpensive to manufacture.
