Definitions
- the invention relates to a vacuum cleaner with a housing which has a dirt chamber which can be closed by a lid, into which a suction nozzle is immersed and into which a filter bag can be inserted, an inlet opening of the filter bag being connectable to the suction nozzle.
- Vacuum cleaners with a dirt chamber into which a filter bag can be inserted are known, for example, from DE 37 14 780 AI.
- This document discloses a vacuum cleaner with a two-part housing, a housing part defining the dirt chamber being articulated to a further housing part and an intermediate carrier being arranged between the two housing parts, onto which the suction nozzle is molded. If the filter bag is to be removed from the dirt chamber, it is necessary to first pivot the housing part defining the dirt chamber into a release position, and then the intermediate carrier articulated on the housing must also be pivoted so that the suction nozzle clears the inlet opening of the filter bag.
- a vacuum cleaner is known in which the suction nozzle is integrally formed on the housing and the cover comprises a further nozzle and a holding device for the filter bag.
- the filter bag can be attached to the cover in such a way that the inlet opening and the further connection piece are aligned with the suction connection piece by placing the cover on the housing, the suction connection piece being immersed in the additional connection piece and in turn immersed in the inlet opening.
- an embodiment of a vacuum cleaner is known in which the suction nozzle is fixed to the lid, and by closing the lid, the suction nozzle can be transferred into a position immersed in the inlet opening of the filter bag.
- a vacuum cleaner is known from utility model DE 94 19 216 Ul, in which the suction nozzle must be separated from the housing in order to be able to insert the filter bag into the dirt chamber.
- the suction nozzle can then be connected to the housing, immersing it in the inlet opening of the filter bag.
- the filter bag can comprise a closing device, with the aid of which the inlet opening can be closed.
- the filter bag filled with dirt can be closed before removal from the dirt chamber, so that it is ensured that no dirt can escape when it is removed. To do this, however, it is first necessary to remove the suction port from the housing.
- the object of the present invention is to develop a vacuum cleaner of the type mentioned at the outset in such a way that it enables simple and hygienic handling when the filter bag is removed from the dirt chamber.
- a vacuum cleaner of the generic type in that the suction nozzle is held back and forth on the housing between a position which plunges into the inlet opening of the filter bag and a position which opens the inlet opening.
- the configuration according to the invention enables easy handling of the vacuum cleaner when inserting and removing a filter bag.
- To insert a filter bag it is only necessary to move the suction nozzle into its releasing position.
- the filter bag can then be inserted into the dirt chamber.
- the filter bag can have a closing device, wherein the inlet opening can be opened after the filter bag has been inserted into the dirt chamber.
- the suction nozzle can then be moved into its position which plunges into the inlet opening of the filter bag.
- the suction nozzle can be moved again into its releasing position so that the filter bag can then be easily removed from the dirt chamber, a particularly hygienic handling being made possible by the inlet opening of the filter bag before it is removed from the dirt chamber, it is closed by means of the closing device held on the filter bag.
- a particularly simple handling of the vacuum cleaner according to the invention can be achieved in a preferred embodiment in that a connecting piece is held on the housing for connecting a suction hose which is in flow connection with the suction piece via the connecting piece.
- the connecting pieces can be molded onto the housing. Alternatively, it can be provided that the connecting piece can be detachably connected to the housing.
- the connection piece establishes a flow connection between the suction piece and a suction hose of the vacuum cleaner, the suction piece being displaceable on the device between its releasing position and its position immersed in the inlet opening of the filter bag. housing is held, while it is not necessary to replace the filter bag to move the connecting piece and the suction hose held on it relative to the housing.
- the suction nozzle is coupled to a pivot lever via a guide mechanism, the suction nozzle being displaceable back and forth by pivoting the pivot lever.
- the pivot lever can be pivoted back and forth by the user between a first pivot position, which corresponds to the releasing position of the suction nozzle, and a second pivot position, which corresponds to the position of the suction nozzle immersed in the inlet opening, the pivoting movement of the pivot lever in using the guide mechanism a displacement movement of the suction nozzle is transmitted.
- the guide mechanism advantageously forms a link guide.
- the link guide can have a sliding guide in which a guide pin is slidably mounted, whereby by generating a relative movement between the sliding guide and the guide pin, a transfer of the pivoting movement of the pivoting lever into a sliding movement of the suction nozzle can be achieved.
- the link guide has a rotating sleeve coupled to the swivel lever, which surrounds the suction nozzle and which is rotatably held on the housing about its longitudinal axis, the rotating sleeve comprising a sliding guide in which a guide pin arranged on the suction nozzle is held displaceably.
- the rotary sleeve can be rotated about its longitudinal axis, so that there is a relative movement between forms the slide guide and the guide pin, so that the suction nozzle can be moved together with the guide pin arranged on it.
- the pivot lever is preferably molded onto the rotating sleeve. This enables particularly cost-effective production.
- a sealing element is arranged between the rotating sleeve and the suction nozzle, since this allows the inflow of false air into the suction nozzle to be avoided in a structurally simple manner.
- the sealing element is designed as a sealing ring surrounding the suction nozzle in the circumferential direction, preferably as an O-ring.
- a particularly interference-resistant design of the vacuum cleaner can be achieved in that the sealing element is held immovably on the suction nozzle. This has the consequence that the sealing element can be moved back and forth together with the suction nozzle.
- a guide part is arranged on the housing, on which the end region of the suction nozzle facing away from the filter bag is in sliding contact, at least in regions. Tilting of the suction nozzle can be prevented in a structurally simple manner by using the guide part. It is advantageous if the guide part is integrally formed on the housing, since this can simplify the assembly of the vacuum cleaner.
- the guide part comprises a guide sleeve into which the end area of the suction nozzle facing away from the filter bag is immersed. It has been shown that an extremely low susceptibility to failure of the vacuum cleaner according to the invention can be achieved by using the guide sleeve.
- a sealing element is arranged between the guide sleeve and the suction nozzle, which prevents the supply of false air into the suction nozzle.
- the sealing element is designed as a sealing ring that can be rolled off on the outside of the suction nozzle and on the inside of the guide sleeve. Due to the rolling ability of the sealing ring, frictional forces between the suction nozzle and the guide sleeve are significantly reduced, so that the displacement of the suction nozzle can be carried out with very little effort and yet the inflow of false air into the suction nozzle is reliably prevented.
- the guide part comprises a guide socket which plunges into the end of the suction socket facing away from the filter bag.
- the guide nozzle forms part of the flow connection between the suction nozzle and the suction hose which can be connected to the connection nozzle, it being advantageous if the guide nozzle also forms a guide for the suction nozzle, for example it can be provided that the suction nozzle on the outside of the Guide sleeve is sliding.
- the guide socket is preferably connected in one piece to the guide sleeve. It is particularly advantageous here if the guide socket, the guide sleeve and the housing form a one-piece molded plastic part.
- the guide socket and the guide sleeve define an annular space between them into which the end region of the suction socket facing away from the filter bag is immersed.
- the swivel lever is arranged in its swivel position corresponding to the immersed position of the suction nozzle within the dirt chamber and can be covered by the cover.
- the swivel lever is therefore only accessible to a user after the cover has been removed. This enables the vacuum cleaner to be operated in a quasi-intuitive manner, since the user generally removes the cover when a filter bag filled with dirt is to be replaced.
- the pivoting lever which is preferably arranged in the area of the inlet opening of the filter bag, and can easily pivot it such that the suction nozzle assumes its position in which the filter bag is opened, in which the filter bag can be removed from the dirt chamber.
- the pivoting lever blocks the placement of the cover on the dirt chamber in its pivoting position corresponding to the releasing position of the suction nozzle. This reduces the risk that the user will put the lid back on the dirt chamber after removing a filter bag without having to put a new filter bag in to have used the dirt chamber. This reduces the risk of the vacuum cleaner being operated without a filter bag inserted in the dirt chamber.
- the swivel lever can be automatically locked in its swivel position corresponding to the releasing position of the suction nozzle by removing the filter bag from the dirt chamber.
- the swivel lever can consequently not be unintentionally swiveled after removing a filter bag in such a way that the lid can be placed on the dirt chamber, but first it is necessary to unlock the swivel lever.
- the pivot lever can be locked by means of a bolt which is resiliently biased into a locking position, the bolt being inserted into the dirt chamber by inserting a filter bag against the action of an elastic restoring force can be transferred to an unlocking position.
- the elastically preloaded bolt thus ensures in a structurally simple manner that the pivot lever is locked when a filter bag is removed from the dirt chamber, and by inserting a filter bag into the dirt chamber, the locking mechanism is automatically released by the bolt against the effect of its elastic restoring force in a Unlocked position is transferred.
- the bolt is designed as a leaf spring which interacts with a locking element of the pivot lever.
- the latching element can, for example, be designed as a radially outwardly projecting latching projection which is molded onto the pivoting lever or onto the suction nozzle.
- Figure 1 is a schematic representation of a vacuum cleaner according to the invention
- Figure 2 is a diagrammatic, partially cut-away view of an upper end portion of the vacuum cleaner from Figure 1;
- FIG. 3 a perspective view in the direction of arrow A from FIG. 2;
- Figure 4 is a sectional view of the upper end portion of the vacuum cleaner shown in Figure 2;
- Figure 5 is a sectional view taken along line 5-5 in Figure 3 before inserting a filter bag and
- Figure 6 is a sectional view corresponding to Figure 5 after inserting a filter bag.
- the drawing schematically shows a vacuum cleaner, generally designated by the reference number 10, which is designed as a so-called style device and has a two-part housing 12 with an upper housing part 13 and a lower housing part 14.
- a style 16 adjoins the upper housing part 13 and carries a handle 17 at its free end.
- the lower housing part 14 accommodates an electric motor and a suction unit in the usual manner and therefore not shown in the drawing and, in combination with the upper housing part 13, defines a dirt chamber 19 which can be covered by a cover 20.
- a recessed grip 21 is formed in the cover 20, by means of which it is easier for the user to put on and take off the cover 20, and a handle 23 is formed on the upper side of the housing 13.
- the vacuum cleaner 10 comprises for cleaning a floor surface a conventional suction nozzle 25, known per se and therefore only shown schematically in the drawing, to which a suction channel 26 connects in the suction flow direction, which runs inside the housing 12 and which protrudes beyond the housing upper part 13 Suction pipe 28 is connected.
- a suction hose 30 is connected to the free end of the suction pipe 28, the end thereof facing away from the suction pipe 28 having an upper side on the upper housing part 13
- Detachably connected connecting piece 32 is in flow connection. This is particularly clear from Figure 2.
- a guide part 34 is formed on the upper housing part 13, which comprises a guide sleeve 36 and a guide socket 38 arranged coaxially therewith and surrounded by the guide sleeve 36 and having an annular space between them Define 40.
- the guide stub 38 is immersed in a suction stub 42, whose lower end region 43 facing away from the guide stub 38 is immersed in the dirt chamber 19, while its upper end region 44 facing the guide stub 38 is immersed in the annular space 40.
- the upper end region 44 is surrounded by a sealing ring 46, which is arranged between the suction nozzle 42 and the guide sleeve 36, wherein it can roll off both on the outside of the suction nozzle 42 and on the inside of the guide sleeve 36 when the suction nozzle 42, such as described below, is displaced in the direction of the longitudinal axis 60.
- a filter bag 47 which is known per se and is therefore only shown in broken lines in the drawing, can be inserted into the dirt chamber 19 and has a filler opening 49 which is also shown only schematically by means of a known and therefore in the drawing shown closing device 50 can be closed.
- the filter bag 47 carries in the area of the filling opening 49 via a holding flange 52, which is known per se and is therefore not shown in the drawing for a better overview, and for fastening the Filter bag 47 within the dirt chamber 19 has two holding strips 54, 56 which are aligned parallel to one another and which engage under the holding flange 52 of the filter bag 47, so that the filter bag 47 can be fixed within the dirt chamber 19.
- the dirt chamber 19 can be suctioned off in the usual way by means of the suction unit already mentioned above, i. H.
- the suction air flow provided by the suction unit starting from the suction nozzle 25 via the suction channel 26, the suction pipe 28 and the suction hose 30, dirt can be transferred through the suction nozzle 42 into the filter bag 47.
- the suction nozzle 42 is surrounded by a rotating sleeve 58 which is aligned coaxially with the suction nozzle 42 and is rotatably mounted in the upper housing part 13 about the longitudinal axis 60.
- the rotary sleeve 58 carries a radially projecting pivot lever 61, and in its upper end area facing the guide part 34, the rotary sleeve 58 has two diametrically opposed, helical guide grooves 62, 63.
- the guide grooves 62, 63 are each penetrated by a guide pin 64 formed on the suction port 42 and projecting radially outward therefrom, to which in the circumferential direction of the suction port 42 there is a guide tab 66, 67 formed in the axial direction on the guide sleeve 36, which define an axially aligned guide channel 69 between them.
- the guide channel 69 forms an axially aligned guide for the guide pin 64.
- a sealing ring 59 is arranged, which is fixed on the outside on the suction port 42.
- the helical guide groove 62 in combination with the guide pin 64 forms a link guide. If the pivot lever 61 is pivoted, then the rotary sleeve 68 is rotated about the longitudinal axis 60, the guide pin 64 due to the relative movement of the guide groove 62 in the axial direction, i. H. is moved back and forth in the longitudinal direction of the guide channel 69. A pivoting movement of the pivot lever 61 thus results in a displacement movement of the suction nozzle 42 in the direction of the longitudinal axis 60.
- the suction nozzle By pivoting the pivot lever 61, the suction nozzle can be moved back and forth between a front position in which it dips into the fill opening 49 of the filter bag 47 and a rear position in which it opens the fill opening 49.
- a locking projection 71 is integrally formed on the rotating sleeve 58, the pivoting lever 61 substantially diametrically opposite, which, when the pivoting lever 61 is pivoted into the pivoting position corresponding to the releasing position of the suction nozzle 42, is at a stop 73 can be applied, which limits the pivoting movement of the pivoting lever 61.
- a bolt in the form of a leaf spring 75 is arranged within the dirt chamber 19, which is biased in the direction of the lower end region 44 of the suction nozzle 42.
- the leaf spring 75 is aligned obliquely to the latching projection 71, so that it counteracts the pivoting lever 61 from the latching projection 71 their elastic restoring force parallel to the longitudinal axis 60 can be elastically bent back so far that the locking projection 71 can pass the leaf spring 75.
- the locking projection 71 then comes to rest against the stop 73 and releases the leaf spring 75. If no filter bag 47 is inserted into the dirt chamber 19, the leaf spring 75 assumes a locking position in which the latching projection 71 resting against the stop 73 is locked between the stop 73 and the leaf spring 75. This is particularly clear from Figure 3.
- the holding flange 52 releases the leaf spring 75 so that, due to its elastic restoring force, it automatically passes into its locking position in which it locks the locking projection 71 abutting the stop 73 and thus also the pivoting lever 61.
- the pivoted lever 61 protrudes outward beyond the outer circumference of the dirt chamber 19 in its locked pivoted position, which corresponds to the releasing position of the suction nozzle 42.
- the cover 20 cannot be placed on the dirt chamber 19.
- the dirt chamber 19 can only be closed by means of the cover 20 after the pivoting lever 61 has been pivoted back in the counterclockwise direction into the interior of the dirt chamber 19 in relation to FIG.
- it is necessary to release the locking of the locking projection 71 by inserting a new filter bag 71 by moving the leaf spring 75 from the retaining flange 52 of the filter bag 47 into its unlocked position.
- the pivot lever 61 can consequently be pivoted back, and then the cover 20 can be placed on the dirt chamber 19, so that the vacuum cleaner 10 can be put into operation again.
