Abstract
Description
Die Erfindung betrifft eine im Haushalt oder in Betrieben angewendete Vorrichtung, mit welcher Luft zur Reinigung der Raumluft oder von verschmutzten Oberflächen angesaugt wird, wobei der Schmutz (Staub), auch größere mit der Luft geförderte Teilchen aller Art, Partikel aus verschiedenen Stoffen, sowie Hausmilben, deren Kot, Schadstoffe wie Formaldehyd und sonstige Allergieschadstoffe, von der Luft getrennt und zur Entsorgung zurückgehalten werden.The The invention relates to a household or in enterprises applied Device with which air for cleaning the room air or of dirty surfaces is sucked in, the dirt (dust), even larger with the air promoted Particles of all kinds, particles of different substances, as well as house mites, their feces, pollutants such as formaldehyde and other allergy pollutants, separated from the air and retained for disposal.
Es ist bekannt, dass Luft mittels eines rotierenden Gebläselaufrads durch eine Abscheidevorrichtung gesaugt wird und entweder in den gleichen Raum zurückgeführt, oder in einen anderen Raum, bzw. in die Außenluft. Alternativ wird nach der Abscheidevorrichtung eine Feinabscheidevorrichtung vor oder hinter dem Gebläselaufrad angeordnet.It It is known that air by means of a rotating Gebläselaufrads is sucked through a separator and either in the returned to the same room, or in another room, or in the outside air. Alternatively, after the separation device before or a Feinabscheidevorrichtung before behind the fan impeller arranged.
Beispielsweise ist die Abscheidevorrichtung ein mechanischer Filter, z.B. ein Filterbeutel, ein Wasserbad bzw. Wassernebel oder ein Zyklon.For example If the separator is a mechanical filter, e.g. a filter bag, a water bath or water mist or a cyclone.
Die Feinabscheidevorrichtung ist beispielsweise ein Mikrofilter, wie HEPA-Filter (High-efficiencyparticulate-air-Filter). Dieser hat die Aufgabe möglichst feine Partikel zurückzuhalten, welche die Abscheidevorrichtung durchlaufen haben.The Feinabscheidevorrichtung is for example a microfilter, such as HEPA filter (high-efficiencyparticulate-air filter). This one has the task as possible withhold fine particles, which have passed through the separation device.
Herkömmliche Feinabscheidevorrichtungen sind ökologisch bedenklich, insbesondere wenn die Abluft in den Wohn- oder Arbeitsraum zurückströmt, da in der Feinabscheidevorrichtung, d.h. in den zurückgehaltenen Rückständen Verkeimungen stattfinden und diese Keime und Schimmelpilze mit der Abluft ausgeblasen werden. Wird mit einem Wasserbad als Abscheidevorrichtung gearbeitet ist diese Gefahr besonders groß, da die nicht zu vermeidende Anfeuchtung der Rückstände den Vorgang begünstigt. Durch die nötige möglichst kleine Filterfeinheit der Feinabscheidevorrichtung und der erwähnten Problematik muss diese öfters gewechselt werden, um auch die ohnehin damit verbundenen Druckverluste nicht noch mehr durch die Rückstände zu erhöhen. Dies bedeutet hohe Betriebskosten. Hohe Druckverluste bewirken eine Verminderung der Saugleistung.conventional Fine separation devices are ecological questionable, especially if the exhaust air in the living or working space flows back, there in the fine separation device, i. in the retained residues germs take place and these germs and molds blown out with the exhaust air become. Is worked with a water bath as a separator is this danger especially great since the unavoidable moistening of the residues favors the process. By the necessary preferably small filter fineness of Feinabscheidevorrichtung and the mentioned problem this has to be done more often be changed, not to the already associated pressure losses even more by the residues increase. This means high operating costs. High pressure losses cause a reduction the suction power.
Deshalb sind derzeit einige Systeme, insbesondere die mit Wasserbad, ohne Feinabscheidevorrichtung ausgestattet. Viel kleine lungengängige Partikel werden dann nicht zurückgehalten. Verschmutzung des Gebläselaufrads, eventuell dessen Antriebmotors und der Raumluft sind die Folgen. Dies führt auch zum Systemausfall und erfordert einen wiederkehrenden Service.Therefore are currently some systems, especially those with water bath, without Fine separation device equipped. Many small respirable particles will not be held back then. Contamination of the blower impeller, possibly its drive motor and the room air are the consequences. This also leads system failure and requires a recurring service.
Aufgabe der Erfindung ist es, diese Nachteile zu vermeiden. Es soll besonders für kleine Partikelchen eine Feinabscheidevorrichtung, vorwiegend zwischen Abscheidevorrichtung und Gebläselaufrad, mit verbesserter Filterwirkung geschaffen werden, welche selbstreinigend ist, d.h. nicht gewartet werden muss, eine geringe konstante Druckdifferenz benötigt und in welcher keine Verkeimung stattfinden kann.task The invention is to avoid these disadvantages. It should be special for little ones Particle a Feinabscheidevorrichtung, mainly between Separator and fan impeller, with improved filtering effect to be created, which self-cleaning is, i. does not need to be maintained, a low constant pressure difference needed and in which no germs can take place.
Lösung der Aufgabe: Überwiegend an, vor und weniger nach der Ansaugfläche des Gebläselaufrads wird, als verbesserte Feinabscheidevorrichtung, ein unwuchtfreier rotierender Rotationsfilter mit einer von außen nach innen durchströmten Filterfläche angebracht. Die gefilterte Luft fliest axial in das oder vom Gebläselaufrad.Solution of Task: Predominantly on, before and less after the suction surface of the fan impeller becomes, as an improved Feinabscheidevorrichtung, unbalance rotating rotary filter mounted with a filtered from outside to inside filter surface. The filtered air flows axially into or out of the blower impeller.
Die Filterfläche ist beispielsweise ein beschichtetes Siebgewebe aus Kunststoff, Textil oder Metall mit definierter Maschenweite, oder jegliche Filterart mit einer wirksamen Filterfeinheit. Die Beschichtung ist schmutz- und wasserabweisend, z.B eine Nanobeschichtung oder mit Lotuseffekt. Der Effekt der Selbstreinigung kann auch durch die Oberfläche vom Material der Filterfläche selbst bewirkt werden. Die Filterfeinheit kann gröber sein als entsprechend die gewünschte noch zurückgehaltene kleinste Partikelgröße, da auch entsprechend der Filterfeinheit kleinere Partikel abgeschleudert werden, wenn die Umfangsgeschwindigkeit des Rotationsfilters größer als die Luftgeschwindigkeit durch die Filterfläche ist. Je höher die Umfangsgeschwindigkeit des Rotationsfilters ist, umso gröber kann die Filterfeinheit sein und umso geringer wird die Druckdifferenz an demselben.The filter area is for example a coated screen mesh made of plastic, Textile or metal with defined mesh size, or any type of filter with an effective filter fineness. The coating is dirty and water-repellent, for example a nano-coating or with lotus effect. The effect of self-cleaning can also be due to the surface of the Material of the filter surface itself be effected. The filter fineness can be coarser as appropriate, the desired still withheld smallest particle size, as well spun smaller particles according to the filter fineness when the peripheral speed of the rotary filter is greater than the air velocity through the filter surface is. The higher the Circumferential speed of the rotary filter is, the coarser can the filter fineness and the lower the pressure difference at the same.
Ist die Abscheidevorrichtung vor dem Rotationsfilter ein Wasserbad, werden kaum Wassertröpfchen durch den Rotationsfilter gelangen und der vom Rotationsfilter abgewiesene Schmutz kann nicht verkeimen, da er in das Wasserbad zurückgeführt wird, welches so wieso ständig erneuert wird. Die Filterfläche wird automatisch immer sauber, ohne Verschmutzung und trocken gehalten.is the separating device in front of the rotary filter a water bath, will hardly be water droplets pass through the rotary filter and rejected by the rotary filter Dirt can not germinate because it is returned to the water bath which so why always is renewed. The filter surface Automatically keeps clean, clean and dry.
