Abstract (en)
The present invention provides a silencer for a vacuum cleaner. The silencer for the vacuum cleaner comprises at least one silencing board (1) mounted in an exhaust channel (3) of the vacuum cleaner for passage of an exhaust airflow from the vacuum cleaner. A plurality of pores (2) are distributed throughout in the silencing board (1). The silencing board (1) is mounted in an orientation perpendicular to the direction of the airflow through the exhaust channel (3). The silencer for a vacuum cleaner can considerably diminish the noise generated by the vacuum cleaner in operation. <IMAGE>
