Abstract
Description
Die Erfindung betrifft eine Blechgleitsohle für eine Staubsaugerdüse mit einem an ihrer Unterseite eingeformten, in Querrichtung verlaufenden Saugmund, der von einer vorderen und einer hinteren Saugmundwand begrenzt ist, und mit schräg ausgerichteten Aufgleitflächen vor und hinter dem Saugmund, wobei jeweils der Übergangsbereich zwischen einer Saugmundwand und der zugeordneten Aufgleitfläche eine Saugmundkante aufweist. Gegenstand der Erfindung ist des Weiteren ein Verfahren zur Auslegung der durch Blechumformung gefertigten Blechgleitsohle.The invention relates to a sheet metal soleplate for a vacuum cleaner with a molded on its underside, extending in the transverse direction suction mouth, which is bounded by a front and a rear Saugmundwand, and with obliquely oriented sliding surfaces in front of and behind the suction mouth, wherein in each case the transition region between a Saugmundwand and the associated sliding surface has a suction mouth edge. The subject matter of the invention is furthermore a method for the design of the sheet metal sole plate manufactured by sheet metal forming.
Da die Schmutzaufnahme bei einer Staubsaugerdüse, insbesondere bei einer statischen Düse, die keine zusätzlichen angetriebenen Reinigungseinrichtungen aufweist, hauptsächlich an den Saugmundkanten eines Saugmundes erfolgt, ist deren Ausgestaltung maßgeblich bestimmend für die gesamten Saugeigenschaften der Staubsaugerdüse, wobei auch bei der Fertigung eine möglichst genaue Einhaltung der bei der Auslegung einer Gleitsohle ermittelten Werte angestrebt wird. Da bei einer scharfkantigen Ausgestaltung der Saugmundkanten die Gefahr besteht einen zu reinigenden Boden, beispielsweise einen Teppich, zu beschädigen und auch sehr hohe Schiebekräfte auftreten können, werden die Saugmundkanten mit einem Radius versehen. Dieser Radius darf jedoch nicht zu groß gewählt werden, da bei einem zu großen Radius das Schmutzaufnahmevermögen deutlich abfällt. Während bei aus der Praxis bekannten thermoplastisch geformten Kunststoffgleitsohlen eine exakte und weitgehend frei wählbare Ausgestaltung der Saugmundkanten möglich ist, sind die Gestaltungsfreiheit und die Reproduzierbarkeit bei der Herstellung von Blechgleitsohlen durch Tiefziehen aufgrund des Blechumformungsprozesses begrenzt.Since the dirt pickup in a vacuum cleaner nozzle, in particular in a static nozzle, which has no additional driven cleaning devices, mainly at the Saugmundkanten a Saugmundes whose design is critically determinative of the entire suction of the vacuum cleaner nozzle, which also in the production as accurate as possible The aim is to achieve values determined in the design of a soleplate. Since in a sharp-edged design of Saugmundkanten the risk exists a floor to be cleaned, such as a carpet to damage and very high sliding forces can occur, the Saugmundkanten are provided with a radius. However, this radius must not be too large, because if the radius is too large, the dirt-holding capacity drops significantly. While an exact and largely arbitrary design of Saugmundkanten is possible in known from practice thermoplastically shaped Kunststoffgleitsohlen, the design freedom and reproducibility in the production of sheet metal soles are limited by deep drawing due to the sheet metal forming process.
Blechgleitsohlen für Staubsaugerdüsen mit den eingangs beschriebenen Merkmalen sind aus der Praxis bekannt. Die im Wesentlichen vertikal verlaufenden Seitenwände gehen bei den bekannten Ausführungen in einem einzigen Bogen in die zugeordnete Aufgleitfläche über, wobei der Bogen eine Saugmundkante definiert. Der Biegewinkel des Bleches, der dem Außenwinkel zwischen einer Saugmundwand und der zugeordneten Aufgleitfläche entspricht, liegt bei den bekannten Ausführungen zwischen 120° und 150°. Das Höhenniveau der von dem Bogen gebildeten Saugmundkante ist durch den Scheitelpunkt des Bogens bestimmt. Bereits eine geringfügige Abweichung des Biegeradius aufgrund von Fertigungstoleranzen oder aufgrund des Austauschs des Formwerkzeuges führt zu einer Änderung des Höhenniveaus der Saugmundkante und so zu einer Fehlausrichtung der durch die Saugmundkanten aufgespannten Fläche, wodurch die Saugeigenschaften signifikant beeinträchtigt werden können.Sheet metal soles for vacuum cleaner nozzles with the features described above are known in practice. The substantially vertically extending side walls are in the known versions in a single arc in the associated slide surface, wherein the arc defines a Saugmundkante. The bending angle of the sheet, which corresponds to the outer angle between a suction mouth wall and the associated sliding surface, is in the known embodiments between 120 ° and 150 °. The height level of the suction mouth edge formed by the sheet is determined by the vertex of the sheet. Even a slight deviation of the bending radius due to manufacturing tolerances or due to the replacement of the mold leads to a change in the height level of the suction mouth edge and thus to a misalignment of the surface defined by the Saugmundkanten surface, whereby the suction properties can be significantly affected.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Blechsohle mit den eingangs beschriebenen Merkmalen anzugeben, deren Saugmundkanten exakt ausgerichtet sind und die leicht zu fertigen ist.Against this background, the invention has for its object to provide a sheet metal sole with the features described above, the Saugmundkanten are aligned accurately and is easy to manufacture.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Saugmundwände jeweils in einem ersten Bogen, der eine Saugmundkante bildet, in ein horizontales Plateau übergehen und dass an das Plateau ein zweiter Bogen anschließt, der in die zugeordnete schräg verlaufende Aufgleitfläche übergeht. Die Erfindung beruht im Kern auf der Idee, den Übergangsbereich zwischen den Saugmundwänden und den jeweils zugeordneten Aufgleitflächen in Abschnitte aufzuteilen und auf diese Weise den Radius der Saugmundkante geometrisch von dem Verlauf der Aufgleitflächen zu entkoppeln.The object is achieved in that the Saugmundwände in each case in a first arc, which forms a Saugmundkante, merge into a horizontal plateau and that connects to the plateau, a second arc, which merges into the associated oblique sliding surface. The invention is based essentially on the idea of dividing the transition region between the suction mouth walls and the respectively associated sliding surfaces into sections and in this way geometrically decoupling the radius of the suction mouth edge from the course of the sliding surfaces.
Da der Übergangsbereich erfindungsgemäß in zwei Bögen mit einem dazwischen angeordneten horizontalen Plateau aufgeteilt ist, ist die Materialbeanspruchung bei der Formgebung geringer als bei der Fertigung der bekannten Blechsohlen. Insbesondere werden die Gefahr einer Rissbildung und einer unerwünscht starken Materialschwächung in den Biegebereichen reduziert.Since the transition region is divided according to the invention in two sheets with a horizontal plateau arranged therebetween, the material stress in the shaping is less than in the production of the known Sheet metal soles. In particular, the risk of cracking and undesirably high material weakening in the bending areas are reduced.
Das Höhenniveau der beiden Saugmundkanten wird entgegen der aus dem Stand der Technik bekannten Ausführungen nicht durch den Scheitelpunkt eines Bogens, sondern durch die Lage des horizontalen Plateaus bestimmt. Die Ausrichtung der von den Saugmundkanten aufgespannten Fläche an der Unterseite des Saugmundes bleibt daher auch bei einer Radiusänderung des ersten Bogens, beispielsweise aufgrund von Fertigungs- oder Werkzeugtoleranzen, erhalten. Insbesondere kann bei der Auslegung und Fertigung der Blechgleitsohle auch der Radius des ersten Bogens unabhängig von den weiteren geometrischen Vorgabewerten frei variiert werden, solange der erste Bogen noch auf dem ursprünglich vorgesehenen Bereich des Plateaus endet.The height level of the two Saugmundkanten is contrary to the known from the prior art embodiments not determined by the vertex of an arc, but by the position of the horizontal plateau. The orientation of the surface spanned by the suction mouth edges on the underside of the suction mouth therefore remains even with a radius change of the first sheet, for example due to manufacturing or tool tolerances. In particular, in the design and manufacture of the sheet metal soleplate, the radius of the first arc can be freely varied independently of the further geometric default values, as long as the first arc still ends on the originally provided area of the plateau.
Dabei ist zu berücksichtigen, dass zur Erzielung optimaler Saugeigenschaften für die Saugmundkante kleine Radien von beispielsweise 0,5 mm angestrebt werden, die bei einer üblichen Blechdicke zwischen 0,4 mm bis 1,5 mm nicht ohne weiteres erreichbar sind. Zur Ermittlung des optimalen Radius des ersten Bogens sind deshalb typischerweise unter Abwägung von fertigungstechnischen und ökonomischen Gesichtspunkten sowie unter Berücksichtigung der Saugeigenschaften einer mit der Blechgleitsohle ausgerüsteten Staubsaugerdüse orientierende Versuche zur Festlegung des optimalen Radius durchzuführen. Im Rahmen einer solchen Optimierung kann erfindungsgemäß der Radius des ersten Bogens bei gleichzeitiger Verringerung der Breite des Plateaus vergrößert oder bei gleichzeitiger Vergrößerung der Breite des Plateaus verringert werden, wobei die weiteren geometrischen Vorgabewerte unverändert bleiben. Der Radius des ersten Bogens liegt im Rahmen der Erfindung vorzugsweise zwischen 0,3 mm und 2 mm, besonders bevorzugt zwischen 0,5 mm und 1 mm. Das Plateau weist dabei in Längsrichtung vorzugsweise eine Breite zwischen 0,5 mm und 4 mm, besonders bevorzugt zwischen 1 mm und 2 mm auf.It should be noted that in order to achieve optimum suction properties for the suction mouth edge small radii of, for example, 0.5 mm are sought, which are not readily available at a conventional sheet thickness between 0.4 mm to 1.5 mm. To determine the optimum radius of the first sheet are therefore typically carrying out a consideration of manufacturing and economic aspects and taking into account the suction properties of a equipped with the metal soleplate vacuum cleaner nozzle oriented experiments to determine the optimum radius. In the context of such an optimization, according to the invention, the radius of the first arc can be increased while reducing the width of the plateau or can be reduced while increasing the width of the plateau, the further geometric default values remaining unchanged. The radius of the first arc is within the scope of the invention preferably between 0.3 mm and 2 mm, more preferably between 0.5 mm and 1 mm. The plateau preferably has in the longitudinal direction a width between 0.5 mm and 4 mm, more preferably between 1 mm and 2 mm.
Im Rahmen einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die hintere und/oder die vordere Saugmundwand im Wesentlichen senkrecht verläuft. Bei einem Winkel der Aufgleitflächen zwischen 30° und 60° gegenüber der Horizontalen ergibt sich dann ein Außenwinkel zwischen den Saugmundwänden und den jeweils zugeordneten Aufgleitflächen zwischen 120° und 150°, der erfindungsgemäß in den ersten Bogen und den zweiten Bogen aufgeteilt ist.Within the scope of a preferred embodiment of the invention, it is provided that the rear and / or the front suction mouth wall runs essentially vertically. At an angle of the sliding surfaces between 30 ° and 60 ° with respect to the horizontal then there is an external angle between the suction mouth walls and the respectively associated sliding surfaces between 120 ° and 150 °, which is divided according to the invention in the first arc and the second arc.
Die schräg verlaufenden Aufgleitflächen müssen im Rahmen der Erfindung nicht völlig gerade verlaufen, sondern können auch ohne Einschränkung über ihre gesamte Länge oder abschnittsweise von der Unterseite der Blechgleitsohle aus gesehen leicht konvex oder konkav gewölbt sein, wobei zur Bestimmung des Winkels zwischen der Aufgleitfläche und der Horizontalen eine mittlere Steigung der Aufgleitfläche gegenüber der Horizontalen zugrunde zu legen ist.The obliquely extending sliding surfaces need not be completely straight in the context of the invention, but can also be seen without restriction over their entire length or sections seen from the bottom of the sheet metal sole slightly curved convex or concave, wherein for determining the angle between the sliding surface and the horizontal an average slope of the sliding surface relative to the horizontal is to be based.
Gegenstand der Erfindung ist auch ein Verfahren zur Auslegung einer durch Blechumformung gefertigten Blechgleitsohle für eine Staubsaugerdüse mit einem an ihrer Unterseite eingeformten in Querrichtung verlaufenden Saugmund, der von einer vorderen und einer hinteren Saugmundwand begrenzt ist, und mit schräg ausgerichteten Aufgleitflächen vor und hinter dem Saugmund, wobei jeweils der Übergangsbereich zwischen einer Saugmundwand und der zugeordneten Aufgleitfläche eine Saugmundkante aufweist, wobei in dem Übergangsbereich ein erster, eine Saugmundkante bildender Bogen und ein zweiter Bogen, der in die zugeordnete schräg verlaufende Aufgleitfläche übergeht, vorgesehen werden und wobei zwischen dem ersten Bogen und dem zweiten Bogen ein horizontales Plateau mit einer Sollbreite von 0,5 mm bis 4 mm vorgesehen wird. Auch wenn bei der Fertigung der Blechgleitsohle die bei der Auslegung festgelegte Sollbreite aus fertigungstechnischen Gründen nicht erreicht wird, ist dennoch eine exakte Höhenausrichtung der Saugmundkanten gewährleistet, solange das Plateau nicht vollständig verschwindet. Um Fertigungstoleranzen auszugleichen und eine geringfügige Variation des Radius des ersten Bogens zu ermöglichen, wird gemäß einer bevorzugten Ausgestaltung des erfindungsgemäßen Verfahrens zur Auslegung der Blechgleitsohle eine Sollbreite von etwa 1,5 mm gewählt.The invention also provides a method for designing a sheet-metal sole-plate manufactured by sheet metal forming for a vacuum cleaner nozzle with a suction mouth formed on its underside, which is delimited by a front and a rear suction mouth wall, and with obliquely oriented sliding surfaces in front of and behind the suction mouth, wherein in each case the transition region between a suction mouth wall and the associated sliding surface has a suction mouth edge, wherein in the transition region a first, a suction mouth edge forming arc and a second arc, which merges into the associated inclined sliding surface, are provided and wherein between the first arc and the second arc a horizontal plateau with a nominal width of 0.5 mm to 4 mm provided becomes. Even if in production of the sheet metal sole the set in the design target width for manufacturing reasons is not achieved, yet an exact height alignment of Saugmundkanten is guaranteed, as long as the plateau does not disappear completely. To compensate for manufacturing tolerances and to allow a slight variation of the radius of the first sheet, a desired width of about 1.5 mm is selected according to a preferred embodiment of the method according to the invention for the design of the sheet metal sole.
Die Art und Ausgestaltung einer Staubsaugerdüse, die mit der erfindungsgemäßen Blechgleitsohle ausgerüstet ist, ist nicht eingeschränkt. Besonders geeignet ist die erfindungsgemäße Blechgleitsohle jedoch für Staubsaugerdüsen, die keine zusätzlich angetriebenen Reinigungseinrichtungen, wie beispielsweise eine Bürstenwalze, aufweisen. Bei solchen statischen Düsen hängt die Saugleistung größtenteils von dem Saugluftstrom im Bereich des Saugmundes und insbesondere von der Gestaltung und Ausrichtung der Saugmundkanten ab. Besonders wichtig ist eine exakte Ausrichtung der beiden Saugmundkanten, wenn die Düse nicht ausschließlich mit den Saugmundkanten, sondern mit Rollen und/oder mit Gleitflächen auf dem zu reinigenden Boden aufliegt.The type and configuration of a vacuum cleaner nozzle, which is equipped with the sheet-metal sole according to the invention, is not limited. However, the sheet metal sole according to the invention is particularly suitable for vacuum cleaner nozzles, which have no additionally driven cleaning devices, such as a brush roller. In such static nozzles, the suction power depends largely on the suction air flow in the region of the suction mouth and in particular on the design and orientation of Saugmundkanten. Particularly important is an exact alignment of the two Saugmundkanten when the nozzle rests not exclusively with the Saugmundkanten, but with rollers and / or with sliding surfaces on the floor to be cleaned.
