Description
Die vorliegende Erfindung betrifft ein Luftausblassystem für einen Trockensauger. Über ein Luftausblassystem kann vom Trockensauger eingesaugte Saugluft als Abluft zur Umgebung ausgeblasen werden. Die Erfindung betrifft ebenfalls einen Trockensauger mit einem solchen Luftausblassystem. Luftausblassysteme bzw. Trockensauger der eingangs genannten Art sind grundsätzlich aus dem Stand der Technik bekannt.The present invention relates to an air exhaust system for a dry vacuum cleaner. An air blow-out system can be used to blow out suction air sucked in from the dry vacuum as exhaust air to the surroundings. The invention also relates to a dry vacuum cleaner with such a Luftausblassystem. Air exhaust systems or dry vacuum cleaner of the type mentioned are basically known from the prior art.
Es ist Aufgabe der vorliegenden Erfindung, ein Luftausblassystem bereitzustellen, das einen kompakten und flexiblen Aufbau eines Trockensauger begünstigt.It is an object of the present invention to provide a Luftausblassystem that favors a compact and flexible construction of a dry vacuum cleaner.
Die Aufgabe wird dadurch gelöst, dass das Luftausblassystem eine in einem Gehäuse des Trockensaugers anzuordnende Aufnahmebucht aufweist, in der wahlweise ein Luftfiltereinsatz oder ein Ausblasadapter aufnehmbar ist, wobei der Ausblasadapter ein Auslassfitting zum Anschluss eines Blasschlauchs aufweist und der Luftfiltereinsatz frei von einem solchen Auslassfitting ist.The object is achieved in that the Luftausblassystem has to be arranged in a housing of the dry vacuum receiving bay in which either an air filter cartridge or a Ausblasadapter is receivable, wherein the Ausblasadapter has a Auslassfitting for connection of a blast hose and the air filter cartridge is free of such an outlet fitting.
Das erfindungsgemäße Luftausblassystem schafft die Grundlage für einen Trockensauger, mit dem - in einem Saugbetrieb - Saugluft über ein Einlassfitting angesaugt werden kann und diese Saugluft als Abluft zur Umgebung ausgeblasen werden kann. Ist in die erfindungsgemäß vorgesehene Aufnahmebucht ein Luftfiltereinsatz aufgenommen, so wird die Abluft gefiltert zur Umgebung durch den Luftfiltereinsatz ausgeblasen. Ist hingegen statt des Luftfiltereinsatzes der Ausblasadapter in der Aufnahmebucht angenommen, so kann an dessen Auslassfitting ein Blasschlauch für einen Blasbetrieb des Trockensaugers angeschlossen werden. Über das Einlassfitting einströmende Saugluft strömt als Abluft demnach durch das Auslassfitting und einen etwaigen daran angeschlossenen Blasschlauch zur Umgebung.The air exhaust system according to the invention provides the basis for a dry vacuum cleaner with which - in a suction operation - suction air can be sucked in via an inlet fitting and this suction air can be blown out as exhaust air to the environment. If an air filter element is accommodated in the receiving bay provided according to the invention, the exhaust air is filtered out to the surroundings through the air filter insert. However, if, instead of the air filter insert, the blow-out adapter in the receiving bay is assumed, a blow hose for a blowing operation of the dry vacuum can be connected to its outlet fitting. Intake air flowing in via the inlet fitting thus flows as exhaust air through the outlet fitting and any blast hose connected thereto to the environment.
Das erfindungsgemäße Luftausblassystem schafft die Grundlage für einen Trockensauger besonders kompakter Bauart.The air exhaust system according to the invention provides the basis for a dry vacuum cleaner of particularly compact design.
Ein solcher Trockensauger ist ausgestattet mit einem erfindungsgemäßen Luftausblassystem, wobei die Aufnahmebucht des Luftausblassystems in dem Gehäuse des Trockensaugers angeordnet ist, und der Trockensauger weiterhin ein zum Anschluss eines Saugschlauchs ausgebildetes Einlassfitting aufweist, das am Gehäuse angeordnet ist und über das die Saugluft im Betrieb eingesaugt wird, wobei sich die Aufnahmebucht über eine Ecke des Gehäuses hinweg erstreckt.Such a dry vacuum is equipped with a Luftausblassystem invention, wherein the receiving bay of Luftausblassystems is disposed in the housing of the dry vacuum, and the dry vacuum further comprises a trained for connection of a suction inlet fitting, which is arranged on the housing and via which the suction air is sucked in operation, wherein the receiving bay extends beyond a corner of the housing away.
Diesbezüglich wurde erkannt, dass aus dem Stand der Technik bekannte Trockensauger beispielsweise an ihrem hinteren Gehäuseende einen Luftauslass aufweisen können, der zum Einstecken eines Blasschlauchs geeignet ist. Hierdurch kann der Trockensauger als sogenannter "Blower" genutzt werden. Als problematisch wurde erkannt, dass je kleiner die Querschnittsfläche der Ausblasöffnung ist, desto höher auch die Ausblasgeschwindigkeit der Abluft und somit eine unerwünschte Staubverwirbelung von Umgebungsstaub ist. Ebenfalls können Benutzer oder Personen in der Umgebung solcher Trockensauger unangenehm "angeblasen" werden. Die beschriebene hohe Ausblasgeschwindigkeit ist insbesondere bei kompakten Trockensaugern ein Problem.In this regard, it has been recognized that known from the prior art dry vacuum can have, for example at its rear end of the housing an air outlet, which is suitable for insertion of a blast hose. As a result, the dry vacuum can be used as a so-called "blower". It has been recognized as problematic that the smaller the cross-sectional area of the blow-off opening, the higher the blow-off speed of the exhaust air and thus an undesirable dust swirling of ambient dust. Likewise, users or people in the vicinity of such dry vacuum cleaners can be unpleasantly "blown". The high blow-off speed described is a problem, in particular in the case of compact dry vacuum cleaners.
In Abkehr dazu weist der erfindungsgemäße Trockensauger eine Aufnahmebucht auf, die sich über eine Ecke des Gehäuses hinweg erstreckt. Durch diese Positionierung über Eck kann am Gehäuse des Trockensaugers Platz gespart werden bzw. ein Auslass mit vergleichsweise hohem Strömungsquerschnitt ermöglicht werden.As a departure from this, the dry vacuum according to the invention has a receiving bay which extends over a corner of the housing. This positioning over corner space can be saved on the housing of the dry vacuum or an outlet with a comparatively high flow cross-section are possible.
Es hat sich als vorteilhaft herausgestellt, wenn der Luftfiltereinsatz und/oder der Ausblasadapter modularer Teil des Luftausblassystems sind.It has been found to be advantageous if the air filter cartridge and / or the blowout adapter are a modular part of the air blower system.
In einer besonders bevorzugten Ausgestaltung ist die Aufnahmebucht als Diffusor ausgebildet. Somit kann bereits eine Reduktion der Ausströmgeschwindigkeit der Abluft erreicht werden.In a particularly preferred embodiment, the receiving bay is designed as a diffuser. Thus, already a reduction of the outflow velocity of the exhaust air can be achieved.
In der Aufnahmebucht kann wenigstens ein Haltedom vorgesehen sein, an dem der Ausblasadapter befestigt werden kann. Vorzugsweise sind zwei Haltedome innerhalb eines Volumens der Aufnahmebucht vorgesehen. Dementsprechend kann der Ausblasadapter ein oder zwei Steck- oder Klemmstifte aufweisen mittels welcher der Ausblasadapter an dem Haltedom oder den Haltedomen befestigt werden kann. Alternativ kann der Ausblasadapter mittels einer Schraubverbindung in der Aufnahmebucht gesichert sein.At least one holding dome may be provided in the receiving bay, to which the discharge adapter may be attached. Preferably, two retaining domes are provided within a volume of the receiving bay. Accordingly, the blowout adapter may have one or two male or female pins by means of which the blowout adapter may be attached to the retaining dome or the retaining domes. Alternatively, the blow-out adapter can be secured in the receiving bay by means of a screw connection.
Es hat sich als vorteilhaft herausgestellt, wenn der Luftfiltereinsatz einen Rahmen mit einer Mehrzahl von Filteröffnungen aufweist. Dadurch kann eine Linearisierung der ansonsten turbulent aus der als Diffusor ausgebildeten Aufnahmebucht ausströmenden Luft erreicht werden.It has proven to be advantageous if the air filter insert has a frame with a plurality of filter openings. As a result, it is possible to achieve a linearization of the otherwise turbulent air flowing out of the receiving bay which is designed as a diffuser.
Der Trockensauger weist vorzugsweise ein im Wesentlichen quaderförmiges Gehäuse auf. Es hat sich als vorteilhaft herausgestellt, wenn sich die Aufnahmebucht wenigstens über 25% der Gesamthöhe des Gehäuses erstreckt. Vorzugsweise nimmt die Aufnahmebucht, bezogen an die beiden an der gemeinsamen Ecke anstehenden Oberflächenanteile des Gehäuses, eine etwa gleich große Querschnittsfläche ein. Mit anderen Worten kann die Aufnahmebucht symmetrisch über der Ecke des im Wesentlichen quaderförmig ausgebildeten Gehäuses des Trockensaugers ausgebildet sein.The dry vacuum preferably has a substantially cuboidal housing. It has proven to be advantageous if the receiving bay extends over at least 25% of the total height of the housing. Preferably, the receiving bay, based on the two at the common corner pending surface portions of the housing, an approximately equal cross-sectional area. In other words, the receiving bay can be formed symmetrically over the corner of the substantially parallelepiped-shaped housing of the dry vacuum.
Es hat sich als vorteilhaft herausgestellt, wenn das Einlassfitting des Trockensaugers und die Aufnahmebucht auf einander gegenüberliegenden Seiten des Gehäuses befindlich sind.It has been found to be advantageous if the inlet fitting of the dry vacuum and the receiving bay are located on opposite sides of the housing.
In einer besonders bevorzugten Ausgestaltung ist der Trockensauger akkubetrieben ausgebildet. Besonders bevorzugt ist der Trockensauger ausschließlich akkubetrieben ausgebildet. In einer weiteren bevorzugten Ausgestaltung ist der Trockensauger tragbar mit einem Gewicht von weniger als 10 kg ausgebildet. Dies schließt vorzugsweise das Gewicht eines zum Betrieb des Trockensaugers vorgesehenen Akkumulators (vorzugsweise 22 Volt-Akku) ein.In a particularly preferred embodiment of the dry vacuum cleaner is battery operated. Particularly preferably, the dry vacuum is designed exclusively battery operated.
