Description

An sich ist die Verwendung von geräuschdämpfenden Sieben bei Staubsaugern bekannt. Diese Siebe umgeben bisher jedoch nur die Schaufeln des Ventilators, um die Kraft des gegen das Flügelradgehäuse geschleuderten Luftstromes zu brechen.The use of noise-dampening sieves in vacuum cleaners is known per se. So far, however, these sieves have only surrounded the blades of the fan to generate the power of the to break against the impeller housing thrown air flow.

Mit dieser Einrichtung kann nicht verhindert werden, daß die aus dem Gehäuse austretende Luft nach wie vor Wirbel bildet, die sich auf die Wandung des Staubsaugers übertragen und dadurch Geräusche bedingen. Im Gegensatz hierzu ist gemäß der Erfindung hinter dem Flügelrad ein Sieb, eingebaut, welches die Luftwirbel parallel zur Gehäusewandung des Staubsaugers ausrichtet. Dadurch wird dieses Gehäuse viel weniger in Schallschwingungen versetzt als bisher. Die Zeichnung veranschaulicht ein Ausführungsbeispiel. This device cannot prevent the leakage from the housing Air continues to form eddies, which are transferred to the wall of the vacuum cleaner and cause noises. In contrast, according to the invention, a sieve is installed behind the impeller, which aligns the air vortex parallel to the housing wall of the vacuum cleaner. This makes this case a lot less set in sound vibrations than before. The drawing illustrates an embodiment.

ao Es bezeichnen α das Staubsaugergehäüse, b seine Lufteintrittsöffnung, c seine Luftaustrittsöffnung, d das unmittelbar hinter der Lufteintrittsöffnung angeordnete Staubfilter, e das Motorgehäuse, das mit dem Ventilatorgehäuse f ein starres Ganzes bildet, das durch as Federn g gegen einen. Gummiring h gepreßt wird und sich so im Außengehäuse elastisch aufgehängt befindet. Das Außengehäuse besteht Vorzugs weise, aus einem schalldämpfenden Stoff. .ao It denote α the Staubsaugergehäüse, b its air inlet opening, c its air outlet opening that arranged directly behind the air inlet opening dust filter, e d, the motor housing connected to said fan housing for a rigid whole is obtained by as springs g against one. Rubber ring h is pressed and is so resiliently suspended in the outer housing. The outer housing is preferably made of a sound-absorbing material. .

In neuer Weise ist das Ventilatorgehäuse f durch einen Siebboden ζ abgeschlossen, dem auf der Luftzutrittsseite ein Filter i' aus Mull oder einem ähnlichen, leicht luftdurchlässigen Stoff vorgelagert sein kann.In a new way, the fan housing f is closed off by a sieve bottom ζ, which can be preceded by a filter i ' made of gauze or a similar, slightly air-permeable material on the air inlet side.
