description

Field of the invention

The present invention relates to a vacuum cleaner with a housing and a removable Staubabscheideeinheit having a lid and a lid lock, and which is arranged in its mounted position on the vacuum cleaner, and the lid lock can be brought into a first and a second position, wherein the lid fixed in the first position of the lid lock on the Staubabscheideeinheit, and in the second position of the lid lock of the Staubabscheideeinheit is detachable, and the vacuum cleaner has a limiting means for fixing the lid lock in the first position. Background of the invention

For example, German Offenlegungsschrift DE 103 50 718 A1 discloses a filter for a vacuum cleaner which is detachably mounted in a dust collecting chamber of a main body of a vacuum cleaner. In the known vacuum cleaner filter, a pair of guide protrusions are formed at least on the lid and / or on the filter body to guide the filter so that it is properly mounted in a dust collecting chamber. A user may mount the filter in the dust collection chamber of the vacuum cleaner using a lid handle. The guide projections of the lid slide down along guide recesses formed on the inner surface of the dust collection chamber, whereby the filter is disposed at a suitable location within the dust collection chamber.

Furthermore, British Patent Application GB 2453995 A discloses a cleaning device in which a filter can be removed via the side of the device. For this purpose, the filter is accessible via a hinged door of the device, which contains a wheel. A side part of the device has a door which is arranged via a hinge on the main part of the device. The door has a wheel as well a fastening device. Next, the known cleaning device on a collecting container. To empty the sump, the user releases a cyclone separator from the main body of the purifier by pressing a release button and removing the cyclone separator. Subsequently, the user presses another release button to release a lock. The collecting container, in which dirt and dust have accumulated, can thus be emptied.

Further, for example, European Patent Publication EP 1938735 A2 is known in which a vacuum cleaner having a dust collecting unit is disclosed. The dust-collecting unit is detachably connected to the vacuum cleaner, and has a closing member fixedly connected on one side to the surface of a lid of the dust-collecting unit and projecting from the lid on the other side and elastically supported. When the dust collecting unit is completely inserted in the corresponding part of the vacuum cleaner, the loose end of the closing part is elastically inserted and blocks the dust collecting unit via a groove on the housing of the vacuum cleaner. To remove the dust collection unit, the user depresses the loose end and pulls out the dust collection unit by its handle.

From the European patent application EP 1728460 A1, for example, a device for fixing and separating a receiving container with a cyclone unit is known. The device has a bow handle, a lock / unlock part and a fixing part. The lock / unlock part fixes and unlocks the handle. In the first position, the connection between the cyclone unit and the dust container is fixed. The handle is blocked in the first position by the blocking and release part. Here, cyclone unit and dust container are firmly connected. If the handle is in a second position, the cyclone unit and dust container can be disconnected. The lock / unlock member has a knob and an elastic member, and is disposed on the handle of the dust collection container. Furthermore, bagless vacuum cleaners are known in which the handle of a dust collecting unit dips into a recess of a housing. There are also known locks for fixing a lid to a Staubabscheideeinheit a vacuum cleaner. Upon actuation of this fixation or an actuating element the lid can be detached from the Staubabscheideeinheit. If the Staubabscheideeinheit arranged on the vacuum cleaner, there is a housing cover over the Staubabscheideeinheit so that it is invisible from the outside.

The problem underlying the invention

The invention has for its object to provide a comparison with the prior art improved vacuum cleaner. In particular, a malfunction of the lid lock a Staubabscheideeinheit the vacuum cleaner should be prevented. Furthermore, a shapely design of Staubabscheideeinheit should be achieved without disturbing protruding parts.

Inventive solution

The reference numbers in all claims have no limiting effect, but are only intended to improve their readability.

The solution of the problem is achieved by a vacuum cleaner with the features of claim 1. Under a vacuum cleaner with electrical energy operated devices for receiving dust to understand, with both mains powered and battery or cordless tools are included. A Staubabscheideeinheit is a device in which the dirt-laden suction air can be cleaned of the dirt. For example, such a Staubabscheideeinheit have a filter bag with or without basket, or a centrifugal separator, and is arranged in the intended operation in its mounted position on the vacuum cleaner. For example, to be able to dispose of the dust and dirt accumulated in it, the Staubabscheideeinheit can be removed from the vacuum cleaner. For emptying, the lid can advantageously be removed from the removed Staubabscheideeinheit.

It is an achievable advantage of the vacuum cleaner according to the invention that the lid lock in the mounted position of the Staubabscheideeinheit is inoperable, - A -

and thereby a release of the lid can be prevented by the Staubabscheideeinheit. This is inventively achievable by the limiting means by which the lid lock can not be brought into the second position and thus can only be in the first position in which it fixes the lid on the Staubabscheideeinheit. By the limiting means is advantageously a restriction of the possible positions of the lid lock in the mounted position of Staubabscheideeinheit reachable to the first position by the limiting means prevents the movement of the lid lock from the first position to the second position. This can be achieved, for example, by the lid lock strikes against the limiting means in a movement from the first position to the second position before reaching the second position.

By means of the invention, an incorrect operation, e.g. the unwanted detachment of the lid from the Staubabscheideeinheit by an operation of the lid lock during the suction process, can be avoided. This is a malfunction of the vacuum cleaner, e.g. a loss of suction through additional unintentional openings, avoidable.

PREFERRED EMBODIMENT OF THE INVENTION Advantageous embodiments and developments, which can be used individually or in combination with one another, are the subject matter of the dependent claims.

In a preferred embodiment of the invention, the lid lock in the installed state of Staubabscheideeinheit is at least partially exposed. In the case of an at least partially open lid lock, at least part of the lid lock can be accessed by the user of the vacuum cleaner during normal operation. Thus, the exposed part of the lid lock can be visible from the outside. As a result, a simple and inexpensive construction of the vacuum cleaner can be achieved.

In a further preferred embodiment, the lid lock on an operating element. Particularly preferably, at least a part of the operating element is exposed in the installed state of the Staubabscheideeinheit. Advantageously, can the lid lock can be actuated by the operating element, for example by the user of the vacuum cleaner can bring the lid lock on the operating element from the first to the second position to lift the lid and can bring from the second to the first position to the lid to fix on the Staubabscheideeinheit. In order to avoid incorrect operation and thus the accidental unlocking of the lid, the control element is advantageously not operable in the mounted position of Staubabscheideeinheit. Particularly preferably, the operating element on a control surface to allow easy operation of the lid lock can. The user can eg press the lid lock by pressing with a finger on the control surface.

The invention further development is preferably provided that the control element in the mounted position of the Staubabscheideeinheit is at least partially flush with a surface of the housing. Particularly preferably, the flush with the surface of the housing part of the control element is exposed. Advantageously, the operating element is housed in the housing so that an actuation and thus an unlocking of the lid can be prevented. This can e.g. be realized by selecting suitable distances from the control element to the housing. By the exposed part of the control element flush with the surface of the housing, and so is with the housing at a level, a shapely design of the vacuum cleaner can be achieved.

In one embodiment of the invention, the limiting means is arranged on the housing. Particularly preferably, the limiting means is a part of the housing. Advantageously, thus, the function of the limiting means can be fulfilled by the housing. As a result, a vacuum cleaner with a reduced number of components can be achieved, which can lead to a lower-cost vacuum cleaner. By means of the limiting means arranged on the housing, a mechanically reliable prevention of the movement of the lid lock from the first to the second position can be achieved in the mounted position of the dust-collecting unit. The realization of the limiting means as part of the housing can advantageously be made possible by means of suitable distances between the housing and the lid lock. According to the invention, it is preferably provided that the Staubabscheideeinheit has a handle. This makes it achievable that the Staubabscheideeinheit when removing it from the vacuum cleaner is easy to handle, for example, to be able to empty the accumulated dirt in the Staubabscheideeinheit easy. In a preferred embodiment of the invention, the housing has a handle recess for receiving the handle in the mounted position of the Staubabscheideeinheit. Advantageously, can be realized in the housing of the vacuum cleaner by the inclusion of the handle in the handle recess a positional fixation of Staubabscheideeinheit. This makes it possible that the Staubabscheideeinheit in the mounted position only in its intended position in which correspond openings in the Staubabscheideeinheit with the corresponding openings of the vacuum cleaner can be arranged on the vacuum cleaner. Next is achievable that by the Aussparrung in the housing easy insertion of Staubabscheideeinheit can be ensured in the housing. In this case, both the visual orientation and the insertion itself can be facilitated by the leadership of the handle in the handle recess. Further, by sinking the handle in the handle recess a shapely formation of the Staubabscheideeinheit can be reached without disturbing protruding parts. Preferably, the limiting means is part of the handle recess.

Particularly preferably, the lid lock on an operating element, which is arranged on the handle. By arranged on the handle lid lock an easily realizable limiting means can be reached, which may be part of the handle recess, for example. Furthermore, it can be achieved that the lid lock arranged on the handle for emptying the dust removal unit can easily be operated by the user. In one embodiment of the invention, the lid lock is movably mounted. Particularly preferably, the lid lock is rotatably mounted. Advantageously, the lid lock has an axis of rotation for this purpose. A movably mounted lid lock can easily be brought into the first or second position, whereby an easy handling is achievable. Furthermore, it can be achieved that a movably mounted lid lock can have a high mechanical reliability.

In one embodiment of the invention, the lid lock on an elastic element. Particularly preferably, the lid lock on a spring.

Advantageously, the lid lock by the elastic element in the first

Position are brought. This can be a particularly easy handling of

Staubabscheideeinheit allow, since the user, for. after emptying the

Staubabscheideeinheit the lid only on the Staubabscheideeinheit must put on, and the lid lock independently from the second position to the first

Position goes, and thus fixed the lid back to the Staubabscheideeinheit.

According to the invention it is preferably provided that the vacuum cleaner has a receiving device, and the Staubabscheideeinheit is arranged in the mounted position in the receiving device. Particularly preferably, the Staubabscheideeinheit is at least partially enclosed in the mounted position of the receiving device. As a result, a high positional stability of the Staubabscheideeinheit in the mounted position can be achieved. Particularly preferably, the lid in the mounted position of the Staubabscheideeinheit flush with the surface of the housing. Advantageously, thereby a shapely design of the vacuum cleaner can be achieved.

The present invention makes it possible with simple structural and cost-effective means to provide a vacuum cleaner with a Staubabscheideeinheit, in which a malfunction of the lid lock, for example, during the suction process can be prevented. In addition, easy operation of the lid lock can be achieved. Next, a shapely design of the vacuum cleaner, eg without protruding parts can be achieved. Brief description of the drawings

Further advantageous embodiments will be described in more detail below with reference to an embodiment shown in the drawings, to which the invention is not limited.

They show schematically:

Fig. 4 shows a vacuum cleaner in a sectional view.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT In the following description of a preferred embodiment of the present invention, like reference characters designate like or similar components.

The embodiment will be explained below with reference to FIGS. 1 to 4. Shown in Fig. 1 is a vacuum cleaner 10 with a housing 1 1, a surface 12 of the

Housing 1 1 and a removable Staubabscheideeinheit 20. In Fig. 2 is the

Vacuum cleaner 10 shown in a perspective sectional view. Fig. 3 shows a detail of the vacuum cleaner 10 according to detail A of Fig. 2. Finally, Fig. 4 shows a

Sectional view of the vacuum cleaner. The Staubabscheideeinheit 20 has a lid 21, a lid lock 23 and a handle 22 and is arranged in its mounted position on the vacuum cleaner 10. In Figs. 1 to 4, the Staubabscheideeinheit 20 is shown in its mounted position. In the assembled position, the Staubabscheideeinheit 20 arranged in a receiving device of the vacuum cleaner 10. This allows a stable position of the Staubabscheideeinheit 20 during operation of the vacuum cleaner 10th

The lid lock 23 can be brought into a first and into a second position, wherein the lid lock 23 is shown for purposes of illustration in the figures only in the first position. In the first position, the lid lock 23 fixes the lid 21 to the dust collecting unit 20. In the second position of the lid lock 23, the lid 21 is detachable from the dust collecting unit 20, e.g. To be able to empty the dirt accumulated in the Staubabscheideeinheit 20. In the installed state of Staubabscheideeinheit 20, ie in the mounted position of Staubabscheideeinheit 20, the lid lock 23 is exposed, and is thus visible. The lid lock 23 has an operating element 24 for operating the lid lock 23. In the mounted position of Staubabscheideeinheit 20, the control element with the surface 12 of the housing 11 is flush. As a result, a particularly attractive design of the vacuum cleaner is achieved. On the operating element 24, a control surface 25 is arranged, via which the user can operate the lid lock 23 particularly easily. For this purpose, the user grasps the handle 22 with his hand and presses with his thumb on the control surface 25. This brings the user the lid lock 23 from the first to the second position, and thus can remove the lid 21 of the Staubabscheideeinheit 20 to the in the Staubabscheideeinheit 20 accumulated dirt to be able to empty.

The vacuum cleaner 10 further comprises a limiting means 14 for fixing the lid lock 23 in the first position. In the mounted position of the Staubabscheideeinheit 20, the possible positions of the lid lock 23 are limited due to the limiting means 14 to the first position. This ensures that the lid 21 of the Staubabscheideeinheit 20 during operation of the vacuum cleaner 10 can not be accidentally solved by operating the lid lock 23 via the control element 24.

The housing 11 of the vacuum cleaner 10 has a handle recess 13 for receiving the handle 22 of the Staubabscheideeinheit 20 in the mounted position of the Staubabscheideeinheit 20. By the handle recess 13 in the housing 11 can easy insertion of Staubabscheideeinheit 20 can be ensured. In this case, both the visual orientation and the insertion itself is facilitated by guiding the handle 22. The limiting means 14 is part of the handle recess 13, and is thus arranged on the housing 11. The limiting means 14 is thus realized via suitable distances between the operating element 24 of the lid lock 23 and the handle recess 13 of the housing 1 1.

The arranged on the handle 22 lid lock 23 is rotatable, so movably mounted, and thus can be easily operated. The lid lock 23 has an illustration, not shown elastic element, which brings the lid lock 23 from the second to the first position.

The present invention makes it possible to provide a vacuum cleaner with a dust collecting unit by simple constructive and inexpensive means, in which misoperation of the lid lock, e.g. can be prevented during the suction process. In addition, easy operation of the lid lock can be achieved. Furthermore, a shapely design of the vacuum cleaner, e.g. can be achieved without protruding parts.

The features disclosed in the foregoing description, the claims and the drawings may be of importance both individually and in any combination for the realization of the invention in its various forms.
