Definitions
- the invention relates to a frame for or with a dust chamber filter for a vacuum cleaner.
- the invention further relates to a vacuum cleaner, in particular a canister vacuum cleaner with such a frame.
- a vacuum cleaner in the sense of the present invention comprises a dust chamber with a suction opening and a suction means space with at least one suction means located therein, for example a blower.
- a partition wall separates the dust space from the suction agent space.
- the partition wall has an inlet opening, via which air drawn in by the at least one suction means passes from the dust space into the suction agent space.
- a partition wall is basically such airtight that air can only pass through the inlet opening from the dust chamber in the Saugffenraum.
- the sucked by the at least one suction air enters from outside via the intake into the dust chamber.
- the dust sucked together with the air is collected in the dust chamber, ie in the dust chamber.
- the Saugschraum has at least one outlet opening, is passed through the air supplied into the Saugffenraum air during operation of the vacuum cleaner out.
- a vacuum cleaner according to the present invention may further comprise an interference protection element, as this example, from the document WO 03/028517 A2 is known.
- an engagement protection element has ribs through which air can pass. The ribs are arranged such that a user can not reach the at least one suction means from the dust space. The engagement protection element thus protects a consumer against injuries by the suction means.
- the engagement protection element is permanently attached, so for example, inextricably connected to the partition to reliably protect at any time in the aforementioned manner.
- the dust chamber is designed for insertion of a dust bag to collect sucked dust in the dust bag.
- a dust bag in the dust chamber which is so connected to the inlet opening that sucked air first passes into the dust bag. Subsequently, air comes out of the dust bag acting as a filter again to flow to the Saugffenraum.
- the dust chamber filter is arranged between the dust chamber and the suction agent space in such a way that dust located in the dust chamber is prevented from entering the absorbent chamber together with air.
- air must pass through the dust chamber filter in order to be able to get from the dust chamber into the suction agent chamber. Although it is intended to collect sucked dust in the dust bag. It can still get dust in the rest of the dust chamber, such as when not properly inserted dust bag.
- the dust chamber filter avoids that such dust in the dust chamber, which is located outside of the dust bag, enters the absorbent chamber. Dust in the suction means compartment could adversely affect the function of a suction means therein.
- a dust chamber filter is held or fixed by a frame.
- the dust chamber filter can be like out of DE 10 2009 002 051 A1 be known firmly connected to the frame or as from the publication DE 43 177 15 C1 be known from a designed as a cassette frame.
- the frame is arranged so movable and / or removable in the vacuum cleaner or designed that an exchange or removal of the dust chamber filter for cleaning is possible.
- a dust bag in such a vacuum cleaner adjoins the dust chamber filter or at least on its frame. If the dust bag fills with dust, the air flow through the dust chamber filter can be adversely affected. The suction power of a vacuum cleaner decreases accordingly.
- a frame comprises the features of claim 1.
- Advantageous embodiments emerge from the subclaims.
- a frame according to claim 1 is provided for a dust chamber filter of a vacuum cleaner with the features mentioned.
- a dust chamber filter is preferably permanently connected to the frame to allow replacement of the filter in a simple and trouble-free manner.
- a dust chamber filter which is present for example in the form of a fleece or fabric with small pores, detachably adjacent to the frame and / or rests against this.
- the frame can be designed as a cassette into which a filter can be inserted in a removable manner.
- the frame is preferably made of plastic and in particular if it is permanently connected to the dust chamber filter.
- the dust chamber filter may be made of paper and / or a cloth.
- the dust chamber filter has pores so that air can pass through the filter.
- the dust chamber filter is also designed to withstand this dust.
- the frame has air ducts for guiding air from the dust chamber of a vacuum cleaner to the dust chamber filter or the dust chamber filter side.
- the dust space filter side is the side of the frame on which the filter is mounted or to which the filter adjoins or abuts during operation of an associated vacuum cleaner.
- the air ducts are open to the side facing away from the dust space filter side and thus faces the dust chamber in a vacuum cleaner. As a result, air can get over a large area from the dust chamber of a vacuum cleaner in the air ducts.
- the air ducts avoid that a dust bag in a dust chamber of a vacuum cleaner can be close to the dust chamber filter.
- the channels thus serve as spacers between dust chamber filter and dust bag.
- a partially dust-filtered dust bag can obstruct the supply of air from the dust chamber to the dust chamber filter.
- An associated vacuum cleaner can therefore maintain its suction even when its dust bag is already partially filled with dust.
- the spacers are formed as flow channels in order to achieve particularly favorable flow conditions, whereby the object of the invention is achieved further improved.
- Dust in the sense of the present invention means those particles which are sucked in by the vacuum cleaner.
- At least one air duct of the frame preferably all air ducts provided with an entrance window.
- An entrance window in the sense of the present invention means an opening provided with an edge on the side opposite to the dust space filter side. By such an edge is avoided that a dust bag can get into the opening area and thus able to reduce the opening area. It is thus ensured a consistently large opening, can pass through the air from the dust chamber in the associated air duct. This further contributes to the fact that the suction power of a vacuum cleaner can be maintained even with partially filled dust bag.
- the entrance window or windows are aligned in such a way that they protrude perpendicularly from the dust space filter side or at least substantially perpendicularly.
- the so-oriented passage area for air through such an opening therethrough so further improved to maintain the suction power of a vacuum cleaner even with partially filled dust bag.
- the inlet window (s) adjoin the dust space filter side in particular laterally. This ensures particularly well that air can get from the dust chamber to the filter.
- a dust chamber preferably has spacers, for example in the form of ribs, which provide a spacing between Side walls of the dust chamber and a dust bag therein can be maintained in such a way that laterally emerging from a dust bag air can flow unhindered to the air ducts or entry windows of air ducts.
- spacers therefore have channel-like structures leading to the entrance windows. This ensures further improved ensures that the suction power of a vacuum cleaner can be maintained even with partially filled dust bag.
- air ducts of the frame are formed by ribs, which preferably protrude perpendicularly or at least substantially perpendicularly from the Staubraumfilterseite.
- Air ducts preferably have a first outer section with a constant cross section and an adjoining section with a tapering cross section.
- An outside section adjoins the edge of the frame.

- the ribs are made permeable to air, in particular by windows in the ribs, and / or have grooves, in particular semicircular grooves, on the side remote from the dust chamber side, ie on the side of the frame opposite the dust chamber side. If an air flow channel of the frame is partially blocked or the associated area section of the filter, air can then pass through at least one corresponding opening and / or through at least one groove into an adjacent channel. It is thus further ensured that the suction power of a vacuum cleaner is not adversely affected by a partially filled dust bag.
- the adjacent to the dust chamber diameter that is, the width of a groove is preferably less than 10 mm, more preferably less than 8 mm, so that a portion of a dust bag can not get into the groove, which would disadvantageously favor a blockage.
- the aforementioned diameter and the depth of the groove are preferably at least 3 mm, more preferably at least 5 mm in order to ensure a sufficiently large air passage.
- the ratio of width to depth of a groove is preferably between 2: 1 to 1: 2, more preferably about 1: 1, to ensure that an adjacent dust bag can not enter a groove such that it becomes clogged.
- each edge of a window should be at least 0.5 mm, preferably at least 1 mm thick or high, viewed from the dust space filter side in the direction of the dust space.
- Ribs of the channels which have a relatively large height, are connected in one embodiment by transverse ribs with a comparatively low height to each other.
- the transverse ribs preferably adjoin the dust space filter side.
- the transverse ribs contribute to mechanical stabilization. Due to their relatively low height, however, they hardly affect the suction power.
- such transverse ribs are arranged in a ring, which contributes particularly well to a mechanical stabilization.
- transverse ribs which are preferably arranged in a middle region in an annular manner, and further transverse ribs which extend in a direction which run parallel or substantially parallel to the narrow sides of the rectangular base surface.
- transverse ribs are also available which contribute to the mechanical stabilization.
- the overall height of the ribs which extends in the direction of the dust chamber seen from the dust chamber filter side, exceeds the overall height of the transverse ribs in one embodiment by more than three times, preferably by more than five times. It has been found that even in the case of plastic material on the one hand sufficient mechanical stability is achieved. On the other hand, the transverse ribs practically do not impede desired air flows. It is further improved the object of the invention achieved.
- the overall height of transverse ribs is for example up to 5 mm, preferably up to 3 mm, particularly preferably up to 2 mm.
- the height of the transverse ribs is preferably at least 0.5 mm, preferably at least 1 mm, in order to ensure the desired mechanical stability even when the frame is made of plastic.
- the overall height of the ribs is preferably at least 10 mm, more preferably at least 12 mm, for example 15 mm and more. By such a height is sufficient Space provided so that air can flow through the air ducts in an appropriate manner, so as to reliably solve the object of the invention can.

- the attachment may be provided by material adhesion, such as by gluing or welding. Alternatively or additionally, one or more positive connections may be present.
- the maximum distance between two ribs is preferably not more than 30 mm, more preferably not more than 25 mm, so as to prevent a dust bag from getting between two ribs and closing the corresponding air duct.
- the minimum distance between two ribs is preferably at least 4 mm, more preferably at least 6 mm in order to provide a width of air ducts which do not unduly hinder desirable airflows.
- the ratio of width of an air duct to the height of an air duct is preferably between 2: 1 to 1: 2, so as to avoid on the one hand that a region of a dust bag can pass between ribs such that the corresponding air duct is closed. On the other hand, such a favorable cross section is provided, which ensures that a desired air flow is not unduly impeded.
- At least one rib or portion of a rib protrudes from other ribs of the air ducts in an embodiment on the side opposite to the dust space filter side. It is achieved so that an adjacent dust bag side is not able to lie flat on the ribs. This helps to keep regular distances between a dust bag and ribs through which air can pass. This further improves that the suction power of a vacuum cleaner can be maintained even with partially filled dust bag.
- the frame is intended for use in a generic vacuum cleaner, so a vacuum cleaner with a dust chamber, an inlet opening into the dust chamber, with a device for attaching a dust bag such that air sucked in via the inlet opening is passed into an attached dust bag, with a Saugffenraum with an outlet opening and at least one suction means therein, in particular an electrically driven suction means for sucking air from the dust chamber.
- the frame is then located between the dust chamber and the Saugffenraum in such a way that air must pass through the dust chamber filter in order to get from the dust chamber into the Saugstoffraum can.
- Such a vacuum cleaner may optionally have one or more of the features mentioned in any combination and in particular additionally an engagement protection element which is firmly connected to the vacuum cleaner. Seen in the direction of flow of the air, the engagement protection element is preferably behind the dust chamber filter.
- FIG. 1 shows a frame 1 with a porous dust chamber filter 2, which is bounded by a peripheral edge 3 and the frame 2 is preferably mounted permanently.
- the edge 3 and attached thereto dust chamber filter 2 form the dust space filter side of the frame 1, which in the case of FIG. 1 is rectangular and represents the base of the frame 1.
- the base is for example 12-18 cm long and 8-12 cm wide.
- the frame 1 has a plurality of air ducts for guiding air from the dust chamber of an associated vacuum cleaner to the dust chamber filter or the dust space filter side 2, 3, which are each bounded on two sides by ribs 4, 4a, 4b, 4c.
- air ducts 4, 4a, 4b, 4c are shown.
- the number of However, air ducts may vary and, for example, in a structure like that in the FIG. 1 it will be expedient to lie between 10 and 20.
- the air ducts formed by the ribs 4, 4a, 4b, 4c are openly accessible to the side facing away from the dust space filter side 2, 3, and thus accessible from the side facing the dust space in a vacuum cleaner.
- a dust bag is adjacent to this open side of the air ducts during operation of an associated vacuum cleaner.
- the ribs 4, 4a, 4b, 4c then serve as spacers between the dust chamber filter 2 and a dust bag, not shown.
- the air ducts which open at the narrow sides of the rectangular base 2, 3, have inlet windows, which are bounded by rib ends 5 and webs 6 and by the adjoining region of the edge 3.
- Each entrance window forms an opening which is provided by a web 6, that is to say with an edge on the side which lies opposite the dust space filter side 2, 3.
- a dust bag resting thereon can get into the provided by such a window opening area.
- FIG. 1 There are four entrance windows on each narrow side. However, the number of entry windows may vary, for example between two and eight. Also, such windows may be provided on the long sides. In one embodiment, it is also possible to arrange webs 6 at other locations along the air ducts in order to avoid that a dust bag between ribs 4, 4a, 4b, 4c can get.

- the ribs 4a, 4b have an inner section 4b bent in such a way that the section 4b towards the center continuously separates the distance to an adjacent rib 4, 4c and as in FIG FIG. 1 shown evenly scaled down.
- Air ducts therefore have a first outer section with a constant cross-section and an adjoining section with a tapering cross-section. More specifically, then reduces the width of each air duct to the middle.
- Each outer portion of a rib 4, 4a, 4b, 4c is adjacent to one end of the edge 3 of the frame 1 and is firmly connected thereto.
- the sections 4a are preferably 1.5 cm long. Air ducts hinder from the edge 3, therefore initially along a distance of 1.5 cm an air flow not due to a decreasing channel width. In this area, air can already pass through the filter 2 into the suction agent space. As a result of the subsequent tapering of each air duct, correspondingly less air passes through.
- the air ducts are as shown at one (in the FIG. 1 Lower) side limited by the dust chamber filter 2 and indeed completely as well as the outer sections of the air ducts, which have a constant cross-section, ie a constant width.
- Ribs 4, 4a, 4b, 4c have on the side facing the dust chamber one or more open to the dust chamber, semi-circular grooves 7, the dust space filter side 2, 3 opposite and preferably at the inner portions 4b of the air ducts, which tapers Have cross sections, as these sections are more likely to be affected than the outer sections, where the cross section and the width does not change.
- the diameter of such a semicircle is preferably between 3 and 10 mm in order to achieve the desired effect on the one hand reliably and on the other hand not mechanically destabilize the frame.
- a rib has one to two semicircular grooves 7. Ribs attached to the narrow sides of the frame are preferably provided with two semicircular grooves 7, since such ribs may be relatively long.
- Ribs which originate from longitudinal sides, that is to say from a side wall 9, preferably have only a semicircular groove 7.
- the outer portions 4a of the ribs 4,4, 4b, 4c are preferably air impermeable and also have no grooves 7 to avoid air turbulence, which could reduce the performance of the vacuum cleaner.
- the frame 1 has transverse ribs 8 with a very low overall height of, for example, only 1 to 2 mm adjacent to the dust chamber filter 2.
- the height of the ribs 4, 4a, 4b, 4c is greater by a multiple than the height of the transverse ribs 8 and seen from the dust space filter side 2.3.
- the height of the ribs 4, 4a, 4b, 4c exceeds at least four times, preferably at least five times, the height of the transverse ribs 8.
- the height of the ribs 4, 4a, 4b, 4c is thus substantially higher than the height of the transverse ribs 8
- Internal transverse ribs 8 are as in FIG FIG. 1 shown arranged in a ring.
- the height of the side walls 9 is less than the height of the adjacent ribs 4c and rib sections 4a. In this way, an entry of air into the corresponding air ducts is made possible even on the long sides, although the vertically projecting from the dust chamber side 2, 3 walls 9 include no entrance window so as to stabilize the frame in the longitudinal direction sufficiently and reliably mechanically.

- Ribs 4, 4a, 4b, 4c terminate at least predominantly in an inner ring 10, which is formed by a wall projecting perpendicularly from the base surface and adjacent to the dust chamber filter. These ends of the ribs 4, 4a, 4b, 4c are integrally connected to the wall 10 and preferably ends evenly distributed around the ring 10 in order to promote favorable flow conditions advantageous. Thus, these too inner ends of the affected ribs held stable.
- the height of the wall 10 is less than the height of the ribs 4, 4a, 4b, 4c. In particular, the height of the wall 10 is less than the height of the walls 9.
- the height of the wall 10 is preferably less than 10 mm and / or more than 5 mm, on the one hand to allow the air in the area inside the Rings 10 even when at the ribs 4, 4a, 4b, 4c adjacent, already partially filled dust bag to arrive and on the other hand to ensure sufficient stability.
- the ring 10 may be provided with a web 11 adjacent to the filter 2 and centered with a knob 12 so as to stabilize the position of the dust chamber filter 2.
- the dust chamber filter 2 is preferably fastened to the button 12, specifically in particular in order to further stabilize the position of the dust chamber filter 2, regardless of the long-term stability of other adhesive or welded connections between the frame 1 and the dust chamber filter 2.
- the frame 1 may also have hooks, for example, four hooks 13, which serve to secure the frame 1 in a vacuum cleaner.
- All webs 6, 8, 11 are at most only a few millimeters high, for example, 0.5 to 4 mm, preferably 1 to 3 mm, such as 2 mm, to provide mechanical stabilization without obstructing air currents to any appreciable extent ,
- the thickness of walls, ribs and webs is 0.5-3 mm, preferably 1-2 mm.
- each rib 4c protrudes from other ribs 4, 4a, 4b of the air ducts on the side opposite to the dust-space filter side 2, 3, such as above all FIG. 3 clarified. It is thus achieved that an adjacent dust bag side is not able to lie flat on the ribs 4, 4a, 4b, 4c.
- FIG. 1 an embodiment is shown in which the adjacent to the respective wall 9 ends of the two ribs 4 c are three to eight mm higher compared to the heights of the adjacent rib portions 4 a.
- the height of the two oppositely disposed ribs 4c advantageously decreases, namely in the case of FIG.
- the heights of all the ribs 4, 4a, 4b, 4c in one embodiment are the same again.
- the height of the ribs 4c in the region of the ring 10 is higher than the height of adjacent ribs.
- an adjacent dust bag is at least at the edge regions by the ribs 4c slightly raised at the walls 9.
- a gap may also remain between the dust bag and the ribs 4c, which can further contribute to maintaining the suction performance of a vacuum cleaner.
- Ribs 4, 4a, 4b, 4c end within the frame, if otherwise a suitable minimum width of air ducts would fall below.
- a minimum width of an air duct is preferably at least 5 mm, more preferably at least 7 mm.
- To pay attention to such a minimum width has proven to be advantageous in order to maintain the performance of a vacuum cleaner reliably even with partially filled dust bag can. For this reason, not all of the ribs 4, 4a, 4b, 4c terminate at the ring 10. Instead, in the case of FIG. 1 four ribs which terminate at the annular web 8.
- a symbol such as an arrow 14 in one or both walls 9, which indicates the extra high end of a rib 4c.
- This protruding end can be particularly easily taken to use, for example, the frame with the attached dust chamber filter or remove it from a vacuum cleaner.
- the arrow 14 facilitates finding such a grip area.
- the arrow can at the same time indicate an appropriate installation direction and / or a gripping of the grip area has the consequence that can only be installed in the correct installation direction.
- the dust chamber filter consists in the FIG. 1 shown frame of a one-piece plastic part.
- the dust chamber filter 2 consists of a fleece, which in the case of FIG. 1 is attached to the underside shown there by gluing or welding and preferably also on the web bottoms, the undersides of the ribs 4, 4a, 4b, 4c and / or the underside of the wall 10, so that the dust chamber filter 2 the loads during operation reliably grown is.
- the FIG. 2 shows a view of the frame FIG. 1 and seen from the dust room.
- the FIG. 3 shows a plan view of a narrow side of the frame with entrance windows.
- an embodiment is shown in which the ribs 4c, although sloping run to the middle, but always higher than adjacent other ribs, including the ring 10, in the FIG. 3 is not visible.

Der Staubraum ist für ein Einsetzen eines Staubbeutels eingerichtet, um angesaugten Staub im Staubbeutel sammeln zu können. Während des Betriebs des Staubsaugers befindet sich daher ein Staubbeutel im Staubraum, der so mit der Eintrittsöffnung verbunden ist, dass angesaugte Luft zunächst in den Staubbeutel gelangt. Im Anschluss daran tritt Luft aus dem als Filter wirkenden Staubbeutel wieder heraus, um zum Saugmittelraum zu strömen.The dust chamber is designed for insertion of a dust bag to collect sucked dust in the dust bag. During operation of the vacuum cleaner is located Therefore, a dust bag in the dust chamber, which is so connected to the inlet opening that sucked air first passes into the dust bag. Subsequently, air comes out of the dust bag acting as a filter again to flow to the Saugmittelraum.
Der Staubraumfilter ist derart zwischen Staubraum und Saugmittelraum angeordnet, dass im Staubraum befindlicher Staub davon abgehalten wird, zusammen mit Luft in den Saugmittelraum zu gelangen. Grundsätzlich muss Luft zwingend den Staubraumfilter passieren, um von dem Staubraum in den Saugmittelraum gelangen zu können. Zwar ist vorgesehen, angesaugten Staub im Staubbeutel zu sammeln. Es kann dennoch Staub in den übrigen Staubraum gelangen, so zum Beispiel bei nicht ordnungsgemäß eingesetztem Staubbeutel. Der Staubraumfilter vermeidet, dass solcher Staub im Staubraum, der sich außerhalb des Staubbeutels befindet, in den Saugmittelraum gelangt. Staub im Saugmittelraum könnte die Funktion eines darin befindlichen Saugmittels nachteilhaft beeinträchtigen.The dust chamber filter is arranged between the dust chamber and the suction agent space in such a way that dust located in the dust chamber is prevented from entering the absorbent chamber together with air. Basically, air must pass through the dust chamber filter in order to be able to get from the dust chamber into the suction agent chamber. Although it is intended to collect sucked dust in the dust bag. It can still get dust in the rest of the dust chamber, such as when not properly inserted dust bag. The dust chamber filter avoids that such dust in the dust chamber, which is located outside of the dust bag, enters the absorbent chamber. Dust in the suction means compartment could adversely affect the function of a suction means therein.
Ein Staubraumfilter wird durch einen Rahmen gehalten oder fixiert. Der Staubraumfilter kann wie aus der
Ein Staubbeutel in einem solchen Staubsauger grenzt an den Staubraumfilter oder zumindest an seinem Rahmen an. Füllt sich der Staubbeutel mit Staub, so kann dadurch die Luftströmung durch den Staubraumfilter hindurch nachteilhaft beeinträchtigt werden. Die Saugleistung eines Staubsaugers vermindert sich entsprechend.A dust bag in such a vacuum cleaner adjoins the dust chamber filter or at least on its frame. If the dust bag fills with dust, the air flow through the dust chamber filter can be adversely affected. The suction power of a vacuum cleaner decreases accordingly.
Es ist Aufgabe der vorliegenden Erfindung, einen Rahmen für einen Staubraumfilter bereitzustellen, der bei einem gattungsgemäßen Staubsauger eine hohe Saugleistung auch bei zumindest teilweise gefülltem Staubbeutel ermöglicht.It is an object of the present invention to provide a frame for a dust chamber filter, which allows for a generic vacuum cleaner high suction even with at least partially filled dust bag.
Zur Lösung der Aufgabe umfasst ein Rahmen die Merkmale des Anspruchs 1. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.To achieve the object, a frame comprises the features of
Ein Rahmen nach Anspruch 1 ist für einen Staubraumfilter eines Staubsaugers mit den eingangs genannten Merkmalen vorgesehen. Ein Staubraumfilter ist vorzugsweise unlösbar mit dem Rahmen verbunden, um einen Austausch des Filters auf einfache und störungssichere Weise zu ermöglichen. Es ist aber auch möglich, dass ein Staubraumfilter, die beispielsweise in Form eines Vlieses oder Gewebes mit kleinen Poren vorliegt, lösbar an den Rahmen angrenzt und/oder an diesem anliegt. Der Rahmen kann als Kassette ausgestaltet sein, in die ein Filter in herausnehmbarer Weise eingelegt sein kann. Der Rahmen besteht bevorzugt aus Kunststoff und zwar insbesondere dann, wenn dieser unlösbar mit dem Staubraumfilter verbunden ist. Der Staubraumfilter kann aus Papier und/oder aus einem Stoff bestehen. Der Staubraumfilter weist Poren auf, so dass Luft durch den Filter hindurchtreten kann. Der Staubraumfilter ist darüber hinaus so beschaffen, dass dieser Staub zurückzuhalten vermag.A frame according to
Der Rahmen weist Luftführungskanäle zur Führung von Luft vom Staubraum eines Staubsaugers zum Staubraumfilter bzw. der Staubraumfilterseite auf. Die Staubraumfilterseite ist die Seite des Rahmens, auf der der Filter angebracht ist oder an die der Filter während des Betriebes eines zugehörigen Staubsaugers angrenzt oder anliegt. Grundsätzlich sind die Luftführungskanäle zu der Seite hin offen, die von der Staubraumfilterseite abgewandt und folglich in einem Staubsauger dem Staubraum zugewandt ist. Hierdurch kann Luft großflächig vom Staubraum eines Staubsaugers aus in die Luftführungskanäle hineingelangen. Durch die Luftführungskanäle wird vermieden, dass ein Staubbeutel in einem Staubraum eines Staubsaugers dicht an dem Staubraumfilter angrenzen kann. Die Kanäle dienen also als Abstandshalter zwischen Staubraumfilter und Staubbeutel. Es wird so vermieden, dass ein teilweise mit Staub gefiltert Staubbeutel die Zufuhr von Luft aus dem Staubraum zum Staubraumfilter behindern kann. Ein zugehöriger Staubsauger vermag seine Saugleistung daher auch dann aufrecht zu erhalten, wenn sein Staubbeutel bereits teilweise mit Staub gefüllt ist. Die Abstandshalter sind als Strömungskanäle ausgeformt, um besonders günstige Strömungsverhältnisse zu erzielen, wodurch die Aufgabe der Erfindung weiter verbessert gelöst wird.The frame has air ducts for guiding air from the dust chamber of a vacuum cleaner to the dust chamber filter or the dust chamber filter side. The dust space filter side is the side of the frame on which the filter is mounted or to which the filter adjoins or abuts during operation of an associated vacuum cleaner. Basically, the air ducts are open to the side facing away from the dust space filter side and thus faces the dust chamber in a vacuum cleaner. As a result, air can get over a large area from the dust chamber of a vacuum cleaner in the air ducts. The air ducts avoid that a dust bag in a dust chamber of a vacuum cleaner can be close to the dust chamber filter. The channels thus serve as spacers between dust chamber filter and dust bag. It is thus avoided that a partially dust-filtered dust bag can obstruct the supply of air from the dust chamber to the dust chamber filter. An associated vacuum cleaner can therefore maintain its suction even when its dust bag is already partially filled with dust. The spacers are formed as flow channels in order to achieve particularly favorable flow conditions, whereby the object of the invention is achieved further improved.
Gelingt es, eine Saugleistung auch bei teilweise gefülltem Staubbeutel besonders gut aufrechtzuerhalten, so gelingt es auch, den Staubbeutel besonders vollständig mit Staub zu beladen.If it is possible to maintain a suction performance particularly well even with a partially filled dust bag, it is also possible to load the dust bag particularly completely with dust.
Staub im Sinne der vorliegenden Erfindung meint solche Partikel, die vom Staubsauger angesaugt werden.Dust in the sense of the present invention means those particles which are sucked in by the vacuum cleaner.
In einer Ausführungsform ist zumindest ein Luftführungskanal des Rahmens, vorzugsweise sämtliche Luftführungskanäle mit einem Eintrittsfenster versehen. Ein Eintrittsfenster im Sinne der vorliegenden Erfindung meint eine Öffnung, die mit einem Rand auf der Seite versehen ist, die der Staubraumfilterseite gegenüber liegt. Durch einen solchen Rand wird vermieden, dass ein Staubbeutel in den Öffnungsbereich hinein gelangen kann und so den Öffnungsbereich zu verkleinern vermag. Es wird so eine gleichbleibend große Öffnung gewährleistet, durch die Luft vom Staubraum in den zugehörigen Luftführungskanal gelangen kann. Dies trägt weiter verbessert dazu bei, dass die Saugleistung eines Staubsaugers auch bei teilweise gefülltem Staubbeutel aufrecht erhalten werden kann.In one embodiment, at least one air duct of the frame, preferably all air ducts provided with an entrance window. An entrance window in the sense of the present invention means an opening provided with an edge on the side opposite to the dust space filter side. By such an edge is avoided that a dust bag can get into the opening area and thus able to reduce the opening area. It is thus ensured a consistently large opening, can pass through the air from the dust chamber in the associated air duct. This further contributes to the fact that the suction power of a vacuum cleaner can be maintained even with partially filled dust bag.
Das oder die Eintrittsfenster sind in einer Ausführungsform so ausgerichtet, dass diese von der Staubraumfilterseite senkrecht oder zumindest im Wesentlichen senkrecht abstehen. Die derart ausgerichtete Durchtrittsfläche für Luft durch eine solche Öffnung hindurch trägt so weiter verbessert zur Aufrechterhaltung der Saugleistung eines Staubsaugers auch bei teilweise gefülltem Staubbeutel bei.In one embodiment, the entrance window or windows are aligned in such a way that they protrude perpendicularly from the dust space filter side or at least substantially perpendicularly. The so-oriented passage area for air through such an opening therethrough so further improved to maintain the suction power of a vacuum cleaner even with partially filled dust bag.
Das oder die Eintrittsfenster grenzen insbesondere seitlich an die Staubraumfilterseite an. Dadurch wird besonders gut sichergestellt, dass Luft aus dem Staubraum zu dem Filter gelangen kann.The inlet window (s) adjoin the dust space filter side in particular laterally. This ensures particularly well that air can get from the dust chamber to the filter.
Um die Saugleistung eines Staubsaugers weiter verbessert aufrechtzuerhalten, sind der oder die Eintrittsfenster angrenzend an den Randbereich der Staubraumfilterseite angeordnet. Ist ein Staubbeutel bereits teilweise gefüllt, so wird so gewährleistet, dass seitlich aus dem Staubbeutel austretende Luft zumindest über diese Eintrittsfenster ungehindert in die zugehörigen Luftführungskanäle gelangen kann. Bevorzugt weist ein Staubraum daher Abstandshalter auf, beispielsweise in Form von Rippen, die einen Abstand zwischen Seitenwänden des Staubraums und einem darin befindlichen Staubbeutel aufrecht erhalten können und zwar derart, dass seitlich aus einem Staubbeutel austretende Luft ungehindert zu den Luftführungskanälen oder Eintrittsfenstern von Luftführungskanälen strömen kann. Insbesondere weisen solche Abstandshalter daher kanalartige Strukturen auf, die zu den Eintrittsfenstern führen. Hierdurch wird weiter verbessert gewährleistet, dass die Saugleistung eines Staubsaugers auch bei teilweise gefülltem Staubbeutel aufrecht erhalten werden kann.In order to further improve the suction performance of a vacuum cleaner, the entrance window or windows are arranged adjacent to the edge area of the dust space filter side. If a dust bag is already partially filled, it is thus ensured that air emerging laterally from the dust bag can pass unhindered into the associated air ducts at least via these inlet windows. Therefore, a dust chamber preferably has spacers, for example in the form of ribs, which provide a spacing between Side walls of the dust chamber and a dust bag therein can be maintained in such a way that laterally emerging from a dust bag air can flow unhindered to the air ducts or entry windows of air ducts. In particular, such spacers therefore have channel-like structures leading to the entrance windows. This ensures further improved ensures that the suction power of a vacuum cleaner can be maintained even with partially filled dust bag.
Um weiter verbessert die Saugleistung eines Staubsaugers auch bei teilweise gefülltem Staubbeutel aufrecht erhalten zu können, sind Luftführungskanäle des Rahmens durch Rippen gebildet, die vorzugsweise senkrecht oder zumindest im Wesentlichen senkrecht von der Staubraumfilterseite abstehen. Mit minimalem Materialaufwand wird so ein gewünschter Abstand zwischen einem Staubbeutel und dem Staubraumfilter während des Betriebes gewährleistet. Der minimale Materialaufwand trägt dazu bei, dass Strömungsverluste minimiert werden, die die Saugleistung eines Staubsaugers nachteilhaft beeinträchtigen könnten.To further improve the suction performance of a vacuum cleaner to be able to maintain even with partially filled dust bag, air ducts of the frame are formed by ribs, which preferably protrude perpendicularly or at least substantially perpendicularly from the Staubraumfilterseite. With a minimum of material, a desired distance between a dust bag and the dust chamber filter during operation is guaranteed. The minimal cost of materials helps minimize flow losses that could adversely affect the suction performance of a vacuum cleaner.
Vorzugsweise weisen Luftführungskanäle einen ersten außen liegenden Abschnitt mit gleichbleibendem Querschnitt und einen sich daran anschließenden Abschnitt mit einem sich verjüngenden Querschnitt auf. Ein außen liegende Abschnitt grenzt an den Rand des Rahmens an. Zwei an einen Kanal angrenzende Rippen, die diesen Kanal also seitlich begrenzen, weisen entlang eines solchen außen liegenden Abschnitts untereinander einen gleich bleibenden Abstand auf. Es wird so erreicht, dass für seitlich eintretende Luft zunächst einmal eine gleichbleibend große Durchtrittsfläche bereitgehalten wird. Erst zur Mitte hin verringert sich der Abstand zwischen den Rippen, so dass sich die Querschnitte der Kanäle dann verjüngen. Es hat sich herausgestellt, dass so die Saugleistung eines Staubsaugers weiter verbessert auch bei teilweise gefülltem Staubbeutel aufrecht erhalten werden kann und zwar insbesondere dann, wenn auch die außen liegenden Abschnitte der Kanäle auf der Staubraumfilterseite zumindest überwiegend durch den Staubraumfilter abgedeckt sind, so dass in diesem Bereich eine großflächige Durchtrittsfläche für Luft zum Saugmittelraum hin bereitsteht.Air ducts preferably have a first outer section with a constant cross section and an adjoining section with a tapering cross section. An outside section adjoins the edge of the frame. Two ribs adjoining a channel, which thus delimit this channel laterally, have a constant distance from one another along such an outer section. It is thus achieved that initially a uniformly large passage area is kept ready for laterally entering air. Only towards the middle of the distance between the ribs decreases, so that the cross sections of the channels then taper. It has been found that so the suction performance of a vacuum cleaner can be maintained even with partially filled dust bag upright and in particular, even if the outer sections of the channels on the dust space filter side are at least predominantly covered by the dust chamber filter, so that in this A large area passage area for air to the Saugmittelraum is ready.
Der erste außen liegende Abschnitt eines solchen Kanals mit gleichbleibendem Querschnitt ist vorzugsweise wenigstens 1 cm lang, besonders bevorzugt wenigstens 1,5 cm lang und / oder nicht länger als 2 cm, vorzugsweise nicht länger als 1,7 cm, um die Saugleistung eines Staubsaugers auch bei teilweise gefülltem Staubbeutel besonders gut aufrecht erhalten zu können. Der Abstand zwischen zwei Rippen verändert sich dann in einem außen liegenden Abschnitt nicht über die vorgenannten Längen. Erst im Anschluss daran verringert sich der Abstand zwischen zwei Rippen und zwar vorzugsweise kontinuierlich zur Mitte hin.The first outboard portion of such a constant section channel is preferably at least 1 cm long, more preferably at least 1.5 cm long and / or not more than 2 cm, preferably not longer than 1.7 cm, about the suction power of a vacuum cleaner as well To be able to maintain particularly good upright with partially filled dust bag. The distance between two ribs then does not change in an outer section over the aforementioned lengths. Only then does the distance between two ribs decrease, preferably continuously towards the center.
Die Rippen sind in einer Ausführungsform insbesondere durch Fenster in den Rippen luftdurchlässig ausgestaltet und / oder weisen Nuten, insbesondere halbkreisförmige Nuten auf der von der Staubraumfilterseite abgewandten Seite auf, also auf der Seite des Rahmens, die der Staubraumfilterseite gegenüber liegt. Ist ein Luftströmungskanal des Rahmens teilweise verstopft oder aber der zugehörige Flächenabschnitt des Filters, so kann dann Luft in der Regel durch zumindest eine entsprechende Öffnung hindurch und/ oder durch zumindest eine Nut hindurch in einen benachbarten Kanal hinein gelangen. Es wird so weiter verbessert sichergestellt, dass die Saugleistung eines Staubsaugers nicht durch einen teilweise gefüllten Staubbeutel nachteilhaft beeinträchtigt wird.In one embodiment, the ribs are made permeable to air, in particular by windows in the ribs, and / or have grooves, in particular semicircular grooves, on the side remote from the dust chamber side, ie on the side of the frame opposite the dust chamber side. If an air flow channel of the frame is partially blocked or the associated area section of the filter, air can then pass through at least one corresponding opening and / or through at least one groove into an adjacent channel. It is thus further ensured that the suction power of a vacuum cleaner is not adversely affected by a partially filled dust bag.
Der an den Staubraum angrenzende Durchmesser, also die Breite einer Nut beträgt bevorzugt weniger als 10 mm, besonders bevorzugt weniger als 8 mm, damit ein Bereich eines Staubbeutel nicht in die Nut gelangen kann, was nachteilhaft eine Verstopfung begünstigen würde. Der vorgenannte Durchmesser sowie die Tiefe der Nut beträgen vorzugsweise wenigstens 3 mm, besonders bevorzugt wenigstens 5 mm, um für einen hinreichend großen Luftdurchlass Sorge zu tragen. Das Verhältnis von Breite zu Tiefe einer Nut liegt vorzugsweise zwischen 2:1 bis 1:2, besonders bevorzugt bei etwa 1:1, um zu gewährleisten, dass ein angrenzender Staubbeutel nicht derart in eine Nut gelangen kann, dass diese verstopft wird.The adjacent to the dust chamber diameter, that is, the width of a groove is preferably less than 10 mm, more preferably less than 8 mm, so that a portion of a dust bag can not get into the groove, which would disadvantageously favor a blockage. The aforementioned diameter and the depth of the groove are preferably at least 3 mm, more preferably at least 5 mm in order to ensure a sufficiently large air passage. The ratio of width to depth of a groove is preferably between 2: 1 to 1: 2, more preferably about 1: 1, to ensure that an adjacent dust bag can not enter a groove such that it becomes clogged.
Sind Rippen mit ein oder mehreren Fenstern versehen, so verhindert der Randbereich des Fensters, der in einem Staubsauger an den Staubbeutel grenzt, dass ein Staubbeutel das Fenster verschließen kann. Daher sind Fenster in Rippen besonders zu bevorzugen. Die Breite und/oder Höhe eines Fensters beträgt vorzugsweise wenigstens 2 mm, besonders bevorzugt wenigstens 4 mm, um hinreichend große Durchtrittsflächen bereitzustellen. Aus Stabilitätsgründen sollte ein jeder Rand eines Fensters wenigstens 0,5 mm, bevorzugt wenigstens 1 mm dick bzw. hoch sein und zwar von der Staubraumfilterseite aus gesehen in Richtung Staubraum.If ribs are provided with one or more windows, the edge area of the window, which adjoins the dust bag in a vacuum cleaner, prevents a dust bag from closing the window. Therefore, windows in ribs are particularly preferable. The width and / or height of a window is preferably at least 2 mm, especially preferably at least 4 mm in order to provide sufficiently large passage areas. For reasons of stability, each edge of a window should be at least 0.5 mm, preferably at least 1 mm thick or high, viewed from the dust space filter side in the direction of the dust space.
Rippen der Kanäle, die eine relativ große Bauhöhe aufweisen, sind in einer Ausführungsform durch Querrippen mit im Vergleich dazu niedriger Bauhöhe miteinander verbunden. Die Querrippen grenzen vorzugsweise an die Staubraumfilterseite an. Die Querrippen tragen zu einer mechanischen Stabilisierung bei. Aufgrund ihrer verhältnismäßig geringen Bauhöhe beeinträchtigen sie allerdings die Saugleistung kaum. Vorzugsweise sind solche Querrippen ringartig angeordnet, was besonders gut zu einer mechanischen Stabilisierung beiträgt.Ribs of the channels, which have a relatively large height, are connected in one embodiment by transverse ribs with a comparatively low height to each other. The transverse ribs preferably adjoin the dust space filter side. The transverse ribs contribute to mechanical stabilization. Due to their relatively low height, however, they hardly affect the suction power. Preferably, such transverse ribs are arranged in a ring, which contributes particularly well to a mechanical stabilization.
Insbesondere bei einer rechteckigen Grundfläche des Rahmens gibt es neben vorzugsweise in einem mittleren Bereich ringartig angeordneten Querrippen weitere Querrippen, die sich in einer Richtung erstrecken, die parallel oder im Wesentlichen parallel zu den schmalen Seiten der rechteckigen Grundfläche verlaufen. Es stehen dann auch in diesem Bereich Querrippen zur Verfügung, die zur mechanischen Stabilisierung beitragen.In particular, in the case of a rectangular base surface of the frame, there are transverse ribs which are preferably arranged in a middle region in an annular manner, and further transverse ribs which extend in a direction which run parallel or substantially parallel to the narrow sides of the rectangular base surface. In this area, transverse ribs are also available which contribute to the mechanical stabilization.
Die Bauhöhe der Rippen, die sich von der Staubraumfilterseite aus gesehen in Richtung Staubraum erstreckt, übersteigt die Bauhöhe der Querrippen in einer Ausführungsform um mehr als das Dreifache, bevorzugt um mehr als das Fünffache. Es hat sich herausgestellt, dass selbst im Fall von Kunststoffmaterial einerseits eine hinreichende mechanische Stabilität erzielt wird. Andererseits behindern die Querrippen gewünschte Luftströmungen praktisch nicht. Es wird so weiter verbessert die Aufgabe der Erfindung gelöst. Die Bauhöhe von Querrippen beträgt beispielsweise bis zu 5 mm, vorzugsweise bis zu 3 mm, besonders bevorzugt bis zu 2 mm. Die Bauhöhe der Querrippen beträgt bevorzugt wenigstens 0,5 mm, bevorzugt wenigstens 1 mm, um die gewünschte mechanische Stabilität auch dann zu gewährleisten, wenn der Rahmen aus Kunststoff besteht.The overall height of the ribs, which extends in the direction of the dust chamber seen from the dust chamber filter side, exceeds the overall height of the transverse ribs in one embodiment by more than three times, preferably by more than five times. It has been found that even in the case of plastic material on the one hand sufficient mechanical stability is achieved. On the other hand, the transverse ribs practically do not impede desired air flows. It is further improved the object of the invention achieved. The overall height of transverse ribs is for example up to 5 mm, preferably up to 3 mm, particularly preferably up to 2 mm. The height of the transverse ribs is preferably at least 0.5 mm, preferably at least 1 mm, in order to ensure the desired mechanical stability even when the frame is made of plastic.
Die Bauhöhe der Rippen beträgt bevorzugt wenigstens 10 mm, besonders bevorzugt wenigstens 12 mm, so zum Beispiel 15 mm und mehr. Durch eine solche Bauhöhe wird genügend Raum bereitgestellt, damit Luft durch die Luftführungskanäle in geeigneter Weise strömen kann, um so zuverlässig die Aufgabe der Erfindung lösen zu können.The overall height of the ribs is preferably at least 10 mm, more preferably at least 12 mm, for example 15 mm and more. By such a height is sufficient Space provided so that air can flow through the air ducts in an appropriate manner, so as to reliably solve the object of the invention can.
Der Filter ist vorzugsweise an den Rippen und / oder an den Querrippen befestigt. Der Filter wird so vor übermäßiger Belastung geschützt. Die Langlebigkeit des Bauteils wird so besonders zuverlässig gewährleistet. Darüber hinaus ist dann der Filter insbesondere auch an einem äußeren umlaufenden Rand des Rahmens befestigt. Die Befestigung kann durch Stoffschluss bereitgestellt sein, so zum Beispiel durch Kleben oder Schweißen. Alternativ oder ergänzend können ein oder mehrere formschlüssige Verbindungen vorhanden sein.The filter is preferably attached to the ribs and / or to the transverse ribs. The filter is thus protected against excessive load. The longevity of the component is guaranteed so particularly reliable. In addition, then the filter is in particular attached to an outer peripheral edge of the frame. The attachment may be provided by material adhesion, such as by gluing or welding. Alternatively or additionally, one or more positive connections may be present.
Der maximale Abstand zwischen zwei Rippen beträgt vorzugsweise nicht mehr als 30 mm, besonders bevorzugt nicht mehr als 25 mm, umso zu verhindern, dass ein Staubbeutel zwischen zwei Rippen gelangen und den entsprechenden Luftführungskanal verschließen kann. Der minimale Abstand zwischen zwei Rippen beträgt bevorzugt wenigstens 4 mm, besonders bevorzugt wenigstens 6 mm, um eine Breite von Luftführungskanälen bereitzustellen, die erwünschte Luftströmungen nicht übermäßig ungünstig behindern.The maximum distance between two ribs is preferably not more than 30 mm, more preferably not more than 25 mm, so as to prevent a dust bag from getting between two ribs and closing the corresponding air duct. The minimum distance between two ribs is preferably at least 4 mm, more preferably at least 6 mm in order to provide a width of air ducts which do not unduly hinder desirable airflows.
Das Verhältnis von Breite eines Luftführungskanals zur Höhe eine Luftführungskanals liegt vorzugsweise zwischen 2:1 bis 1:2, um so einerseits zu vermeiden, dass ein Bereich eines Staubbeutels derart zwischen Rippen gelangen kann, dass der entsprechenden Luftführungskanal verschlossen wird. Andererseits wird so ein günstiger Querschnitt bereitgestellt, durch den sichergestellt wird, dass eine erwünschte Luftströmung nicht übermäßig behindert wird.The ratio of width of an air duct to the height of an air duct is preferably between 2: 1 to 1: 2, so as to avoid on the one hand that a region of a dust bag can pass between ribs such that the corresponding air duct is closed. On the other hand, such a favorable cross section is provided, which ensures that a desired air flow is not unduly impeded.
Zumindest eine Rippe oder ein Abschnitt einer Rippe steht gegenüber anderen Rippen der Luftführungskanäle in einer Ausführungsform auf der Seite hervor, die der Staubraumfilterseite gegenüberliegt. Es wird so erreicht, dass eine angrenzende Staubbeutelseite nicht eben auf den Rippen aufzuliegen vermag. Dies trägt dazu bei, dass regelmäßig Abstände zwischen einem Staubbeutel und Rippen verbleiben, durch die Luft hindurch gelangen kann. Hierdurch wird weiter verbessert erreicht, dass die Saugleistung eines Staubsaugers auch bei teilweise gefülltem Staubbeutel aufrecht erhalten werden kann.At least one rib or portion of a rib protrudes from other ribs of the air ducts in an embodiment on the side opposite to the dust space filter side. It is achieved so that an adjacent dust bag side is not able to lie flat on the ribs. This helps to keep regular distances between a dust bag and ribs through which air can pass. This further improves that the suction power of a vacuum cleaner can be maintained even with partially filled dust bag.
Der Rahmen ist für die Verwendung in einem gattungsgemäßen Staubsauger vorgesehen, also einem Staubsauger mit einem Staubraum, einer Eintrittsöffnung in den Staubraum, mit einer Einrichtung für das Anbringen eines Staubbeutels derart, dass über die Eintrittsöffnung angesaugte Luft in einen angebrachten Staubbeutel geleitet wird, mit einem Saugmittelraum mit einer Austrittsöffnung und zumindest einem darin befindlichen Saugmittel, insbesondere einem elektrisch antreibbaren Saugmittel für ein Ansaugen von Luft aus dem Staubraum. Der Rahmen befindet sich dann zwischen dem Staubraum und dem Saugmittelraum und zwar derart, dass Luft den Staubraumfilter passieren muss, um vom Staubraum in den Saugmittelraum gelangen zu können. Ein solcher Staubsauger kann optional ein oder mehrere der eingangs genannten Merkmale in beliebiger Kombination aufweisen und zwar insbesondere zusätzlich ein Eingriffsschutzelement, welches fest mit dem Staubsauger verbunden ist. In Strömungsrichtung der Luft gesehen befindet sich das Eingriffsschutzelement vorzugsweise hinter dem Staubraumfilter.The frame is intended for use in a generic vacuum cleaner, so a vacuum cleaner with a dust chamber, an inlet opening into the dust chamber, with a device for attaching a dust bag such that air sucked in via the inlet opening is passed into an attached dust bag, with a Saugmittelraum with an outlet opening and at least one suction means therein, in particular an electrically driven suction means for sucking air from the dust chamber. The frame is then located between the dust chamber and the Saugmittelraum in such a way that air must pass through the dust chamber filter in order to get from the dust chamber into the Saugmittelraum can. Such a vacuum cleaner may optionally have one or more of the features mentioned in any combination and in particular additionally an engagement protection element which is firmly connected to the vacuum cleaner. Seen in the direction of flow of the air, the engagement protection element is preferably behind the dust chamber filter.

Die
Der Rahmen 1 weist eine Vielzahl von Luftführungskanälen zur Führung von Luft vom Staubraum eines zugehörigen Staubsaugers zum Staubraumfilter bzw. der Staubraumfilterseite 2, 3 auf, die jeweils an zwei Seiten durch Rippen 4, 4a, 4b, 4c begrenzt sind. Im Fall der
Die durch die Rippen 4, 4a, 4b, 4c gebildeten Luftführungskanäle sind zu der Seite offen zugänglich, die von der Staubraumfilterseite 2, 3 abgewandt ist, und damit von der Seite zugänglich, die dem Staubraum in einem Staubsauger zugewandt ist. An diese offene Seite der Luftführungskanäle grenzt während des Betriebs eines zugehörigen Staubsaugers ein Staubbeutel. Die Rippen 4, 4a, 4b, 4c dienen dann als Abstandshalter zwischen dem Staubraumfilter 2 und einem nicht dargestellten Staubbeutel.The air ducts formed by the
Die Luftführungskanäle, die an den Schmalseiten der rechteckige Grundfläche 2, 3 einmünden, weisen Eintrittsfenster auf, die durch Rippenenden 5 und Stege 6 sowie durch den daran angrenzenden Bereich des Randes 3 begrenzt sind. Ein jedes Eintrittsfenster bildet eine Öffnung, die durch einen Steg 6, also mit einem Rand auf der Seite versehen ist, die der Staubraumfilterseite 2, 3 gegenüberliegt. Durch einen solchen Steg 6 wird vermieden, dass ein darauf aufliegender Staubbeutel in den durch ein solches Fenster bereitgestellten Öffnungsbereich hinein gelangen kann. Im Fall der
Es hat sich als strömungsgünstig herausgestellt, Eintrittsfenster, die an den Eckbereich einer Schmalseite angrenzen, wie in der
Die durch Enden von Rippen gebildeten Fensterbegrenzungen 5 eines jeden Eintrittsfensters stehen von der Staubraumfilterseite 2, 3 senkrecht ab. Dadurch stehen die durch die Eintrittsfenster bereitgestellten Durchtrittsflächen ebenfalls senkrecht von der Staubraumfilterseite 2, 3 ab. Die Eintrittsfenster erstrecken sich wie dargestellt vom Rand 3 aus und zwar angrenzend an den Staubraumfilter 2.The
Die Rippen 4, 4a, 4b, 4c stehen senkrecht von der Staubraumfilterseite 2, 3 ab. Rippen 4a, 4b weisen jeweils einen ersten, außen liegenden Abschnitt 4a auf, der parallel zu benachbarten, geradlinig verlaufenden Rippen 4, 4c verläuft oder aber zu benachbarten Abschnitten 4a und/ oder Bereichen von Seitenwänden 9 des Rahmens. Die Rippen 4a, 4b weisen einen innenliegenden, derart abknickenden Abschnitt 4b auf, dass der Abschnitt 4b zur Mitte hin den Abstand zu einer benachbarten Rippe 4, 4c kontinuierlich und wie in
Rippen 4, 4a, 4b, 4c weisen an der dem Staubraum zugewandten Seite ein oder mehrere zum Staubraum hin offene, halbkreisförmige Nuten 7 auf, die der Staubraumfilterseite 2, 3 gegenüberliegt und zwar vorzugsweise bei den innen liegenden Abschnitten 4b der Luftführungskanäle, die sich verjüngende Querschnitte aufweisen, da diese Abschnitte leichter beeinträchtigt werden als die außen liegenden Abschnitte, bei denen sich der Querschnitt sowie die Breite nicht verändert. Der Durchmesser eines solchen Halbkreises liegt vorzugsweise zwischen 3 und 10 mm, um die angestrebte Wirkung einerseits zuverlässig zu erzielen und andererseits den Rahmen mechanisch nicht zu destabilisieren. Vorzugsweise weist eine Rippe ein bis zwei halbkreisförmige Nuten 7 auf. Rippen, die an den schmalen Seiten des Rahmens enden, sind vorzugsweise mit zwei halbkreisförmigen Nuten 7 versehen, da solche Rippen relativ lang sein können. Rippen, die von Längsseiten ausgehen, also von einer Seitenwand 9, weisen bevorzugt nur eine halbkreisförmige Nut 7 auf. Die außen liegenden Abschnitte 4a der Rippen 4,4, 4b, 4c sind vorzugsweise Luft undurchlässig und weisen auch keine Nuten 7 auf, um Luftverwirbelungen zu vermeiden, die die Leistungsfähigkeit des Staubsaugers vermindern könnten.
Der Rahmen 1 weist Querrippen 8 mit sehr niedriger Bauhöhe von beispielsweise lediglich 1 bis 2 mm angrenzend an den Staubraumfilter 2 auf. Die Höhe der Rippen 4, 4a, 4b, 4c ist um ein Vielfaches größer als die Höhe der Querrippen 8 und zwar von der Staubraumfilterseite 2,3 aus gesehen. Insbesondere übersteigt die Höhe der Rippen 4, 4a, 4b, 4c wenigstens um ein Vierfaches, bevorzugt wenigstens um ein Fünffaches die Höhe der Querrippen 8. Die Höhe der Rippen 4, 4a, 4b, 4c ist also wesentlich höher als die Höhe der Querrippen 8. Innenliegende Querrippen 8 sind wie in der
Rippen 4, 4a, 4b, 4c enden zumindest überwiegend bei einem inneren Ring 10, der durch eine senkrecht von der Grundfläche abstehende Wand gebildet wird und an den Staubraumfilter angrenzt. Diese Enden der Rippen 4, 4a, 4b, 4c sind einteilig mit der Wand 10 verbunden und enden vorzugsweise gleichmäßig verteilt um den Ring 10 herum, um gleichmäßige Strömungsverhältnisse vorteilhaft zu begünstigen. Somit werden auch diese inneren Enden der betroffenen Rippen stabil gehalten. Die Höhe der Wand 10 ist geringer als die Höhe der Rippen 4, 4a, 4b, 4c. Insbesondere ist die Höhe der Wand 10 darüber hinaus geringer als die Höhe der Wände 9. Die Höhe der Wand 10 beträgt vorzugsweise weniger als 10 mm und/oder mehr als 5 mm, um einerseits es der Luft zu ermöglichen, in den Bereich im Inneren des Rings 10 auch bei an den Rippen 4, 4a, 4b, 4c anliegendem, bereits teilweise gefülltem Staubbeutel gelangen zu können und um andererseits für hinreichende Stabilität zu sorgen. Der Ring 10 kann mit einem Steg 11 versehen sein, der an den Filter 2 angrenzt und der mittig einen Knopf 12 umfasst, um so die Lage des Staubraumfilters 2 zu stabilisieren. An dem Knopf 12 ist vorzugsweise der Staubraumfilter 2 befestigt und zwar insbesondere formschlüssig, um die Lage des Staubraumfilters 2 weiter zu stabilisieren und zwar unabhängig von der Langzeitstabilität von sonstigen Kleb - oder Schweißverbindungen zwischen dem Rahmen 1 und dem Staubraumfilter 2.
Der Rahmen 1 kann darüber hinaus noch über Haken, beispielsweise vier Haken 13 verfügen, die der Befestigung des Rahmens 1 in einem Staubsauger dienen.The
Sämtliche Stege 6, 8, 11 sind maximal nur wenige Millimeter hoch, so zum Beispiel 0,5 bis 4 mm, vorzugsweise 1 bis 3 mm wie zum Beispiel 2 mm, um für eine mechanische Stabilisierung zu sorgen, ohne Luftströmungen im nennenswerten Umfang zu behindern. Die Stärke von Wänden, Rippen sowie Stegen beträgt 0,5-3 mm, vorzugsweise 1-2 mm.All
Zumindest ein randseitiger Abschnitt einer jeden Rippe 4c steht gegenüber anderen Rippen 4, 4a, 4b der Luftführungskanäle auf der Seite hervor, die der Staubraumfilterseite 2, 3 gegenüber liegt, wie vor allem die
Rippen 4, 4a, 4b, 4c enden innerhalb des Rahmens dann, wenn andernfalls eine zweckmäßige Mindestbreite von Luftführungskanälen unterschritten würde. Eine solche Mindestbreite eines Luftführungskanals beträgt vorzugsweise wenigstens 5 mm, besonders bevorzugt wenigsten 7 mm. Auf eine solche Mindestbreite zu achten, hat sich als vorteilhaft herausgestellt, umso die Leistungsfähigkeit eines Staubsaugers auch bei teilweise gefüllten Staubbeutel zuverlässig aufrecht erhalten zu können. Aus diesem Grund enden nicht sämtliche Rippen 4, 4a, 4b, 4c am Ring 10. Stattdessen gibt es im Fall der
In einer Ausführungsform gibt es darüber hinaus ein Symbol wie zum Beispiel eine Pfeildarstellung 14 in einer oder beiden Wänden 9, die auf das besonders hohe Ende einer Rippe 4c hinweist. Dieses vorstehende Ende kann besonders leicht ergriffen werden, um beispielsweise den Rahmen mit dem daran befestigten Staubraumfilter einzusetzen oder aus einem Staubsauger herauszunehmen. Der Pfeil 14 erleichtert das Auffinden eines solchen Griffbereichs. Der Pfeil kann zugleich auf eine zutreffende Einbaurichtung hinweisen und/ oder ein Ergreifen des Griffbereichs hat zur Folge, dass nur noch in zutreffender Einbaurichtung eingebaut werden kann.In one embodiment, there is also a symbol, such as an
