Vacuum cleaner with removable lid

description

Field of the invention

The present invention relates to a vacuum cleaner with a housing and a lid, wherein the lid is connected via a hinge to the housing and adapted for positively covering a chamber in the housing, the joint has a first hinge part and a second hinge part, which via a hinge connection with each other are movably connected, and the first hinge part is fixedly connected to the housing. Furthermore, the present invention relates to a cover for such a vacuum cleaner.

Background of the invention

A first example of a vacuum cleaner with a lid for closing a vacuum cleaner bag chamber is disclosed in U.S. Pat. Patent US 4,554,700 known. The lid is attached via a hinge with a stop directly on the housing. The hinge comprises a slider attached to the lid which runs in a guide provided in a channel in the housing.

Similarly, from U.S. Pat. Patent US 5,233,722 known to connect a lid via a built-in lid hinge with the housing. In this case, the hinge itself is designed to release the connection in case of incorrect operation. For this purpose, a pin of the joint can be levered out of the housing-mounted socket joints.

Furthermore, from the German utility model DE 9100758 U1 a vacuum cleaner with a hinged on a swivel joint on the housing lid is known, in which an integrally formed on the lid hinge arm runs in a guide of the housing. By cooperating with a stop edge on the housing stop lug a release of the cover from the housing at normal force is prevented. At elevated The action of force can release the stop lug from the stop edge by the elasticity inherent in the hinge arm and the guide and release the cover in order to prevent damage.

The problem underlying the invention

The invention has for its object to provide a comparison with the prior art improved vacuum cleaner. For example, the vacuum cleaner should have an improved tolerance against incorrect operation of a lid and can facilitate the replacement of a damaged lid. Furthermore, the invention has for its object to provide a comparison with the prior art improved vacuum cleaner cover.

Solution According to the Invention The reference numbers in all claims have no limiting effect but are merely intended to improve their readability.

The solution of the problem with respect to the vacuum cleaner is achieved by a vacuum cleaner with the features of claim 1. The solution of the object with respect to the vacuum cleaner cover is achieved by a cover with the features of claim 14th

Under a vacuum cleaner in the present case are understood to be powered by electrical energy devices for receiving dust and small parts, with both mains powered and battery or battery powered devices are included. Vacuum cleaners usually have chambers which serve, for example, for storing various nozzle attachments, for receiving a vacuum cleaner bag or a dust filter for filtering the escaping air. Such chambers are usually covered with lids for protection as well as for aesthetic reasons. The chambers may, for example, be formed by the housing or be limited in part by the housing wall and one or more further elements of the vacuum cleaner. Common to such chambers is that they are covered with a lid. In operation, such lids are usually closed, but must be able to access the object located in the chamber, eg to replace a filter, to change a Saugansatzes or to change the vacuum cleaner bag can be opened. With some known lids there is a risk that they will be damaged by improper handling. For example, a lid may be exposed to a defective load when the lid is moved or loaded beyond the intended opening angle. Another example of a defective load may be the action of a force that does not correspond to the direction of joint movement. In addition to the damage of the lid can also be a coupling of the cover to the vacuum cleaner, such as the joint producing joint or a joint fixing component of the vacuum cleaner, be exposed to the risk of damage.

To come before any damage to such a cover or the articulated coupling before or even to the replacement of a damaged

To facilitate covers, the invention is based on the idea to perform the connection between the lid and joint detachable. Under a releasable connection in this case is a compound to understand that can be solved by the action of an external force on the lid. Examples of such a releasable connection include a plug-in connection, a snap-in connection, a clamping connection and a

Magnetic connection.

It is a further achievable advantage of the invention that, in the case of an otherwise damaged lid, by deliberately exerting a force on the lid and thus on the detachable connection, the connection between lid and vacuum cleaner is released and then e.g. the damaged lid can be replaced by another one.

In embodiments of the vacuum cleaner, this has a housing and a lid. In this case, the lid is connected via a hinge to the housing and designed for the positive covering a chamber in the housing. The joint comprises a first joint part and a second joint part. The first joint part and the second joint part are movably connected to each other via a hinge connection. The first - A -

Joint part can be directly or indirectly connected to the housing. The second hinge part is releasably connected to the lid via a detachable connection.

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 advantageous embodiments of the invention, the connection may be designed such that the cover detaches from the second hinge part at a predetermined force approach to the lid. By the particular design of the connection, the force required to release the detachable connection, i. to release the cover from the second hinge part, be predetermined. For example, the second connector can be made of elastically deformable material, which allows the solution of the compound due to its deformation from the predetermined force approach.

The compound can e.g. be designed as a plug-in connection, snap-in connection, clamp connection or magnetic connection. It is also possible for a plurality of connections to be provided, preferably at several points, wherein these connections can be made with the same or with different types of connection. For example, two connectors can be present at a certain distance.

In advantageous embodiments of the invention, the first hinge part may be at least partially formed by the housing. Then, at least a part of the first joint part is formed as a structural unit with a portion of the housing. Alternatively or to a certain extent, a part of the first joint part can be formed by an independent component that is firmly connected to the housing. In some embodiments of the invention, the housing is designed such that it covers the first hinge part at least partially towards the outside. In this case or in other embodiments, the first hinge part can not be arranged accessible from the outside within the housing. This can be a pleasant aesthetic Appearance of the vacuum cleaner can be achieved. Furthermore, in this way, the joint itself can be protected from external influence.

Furthermore, the vacuum cleaner can comprise a component arranged in the interior of the housing and the first joint part can be fixedly connected via the component to the vacuum cleaner, preferably to the housing of the vacuum cleaner. By this embodiment of the invention, the assembly of the vacuum cleaner can be facilitated by making it possible that first the hinge is mounted on the lid and then the hinge with lid on the first hinge part is firmly connected to the vacuum cleaner. In some embodiments of the invention, the second hinge part comprises a hinge axis and the first hinge part is designed to guide the hinge axis. In general, the joint may e.g. be designed as a hinge in which the hinge axis is rotatable about a rotation axis. In some embodiments, the second hinge part has a first tab and the lid has a first mating tab. In this case, the first plug-in lug and the first mating lug can form at least a part of the detachable connection in the assembled state. For this purpose, the plug-in projection and the counter-plug approach, for example, have an interacting combination of a Einrastzahn in one of the lugs and an opening for receiving the Einrastzahns in the associated approaches.

Advantageously, in some embodiments, the second hinge part and the lid in the assembled state of the lid are detachably connected to each other in two places. In this case, the compounds may have different directional characteristics in terms of their solubility at an acting force at the two locations. For example, a further outward position (based on, for example, the attachment of a centrally arranged dust tube) can be formed such that, in the event of a lateral force application and a point located further inward, it will become detached in the event of a force direction in the direction of the opening movement. In another aspect of the invention, covers for vacuum cleaners of the type described above have an attachment for releasable connection to a second hinge part of a cover and housing connecting hinge.

The present invention can provide, by simple, constructive and inexpensive means, the provision of vacuum cleaners which permit easy replacement of a lid to cover a chamber. In particular, such vacuum cleaner can have a reduced susceptibility to damage of lids.

Detailed description with reference to several embodiments In FIGS. 1 to 6, a first embodiment of a vacuum cleaner 10 is shown. Additional examples of detachable connections will be explained with reference to FIGS. 7 to 9.

In Fig. 1, the vacuum cleaner 10 has a housing 12 which essentially determines the outer shape of the vacuum cleaner 10. The vacuum cleaner 10 further comprises a dust separating unit 14 for filtering dust particles and minute particles from the sucked air. The air is sucked in, for example through a suction pipe, which can be attached to a suction pipe 16 approach. The suction force of the vacuum cleaner 10 is determined by a knob 18. The vacuum cleaner 10 is additionally provided two symmetrically formed chambers. In a first chamber covered by a lid 20A, e.g. a fine dust filter for the exiting air of the vacuum cleaner 10. In a second chamber, covered by a cover 2OB, are e.g. different suction approaches for the intake manifold. The covers 2OA and 2OB are releasably secured to the housing via hinges 22A and 22B (the arrows in Fig. 1 indicate the position). The hinges 22A and 22B are covered outwardly by the covers 24A and 24B to provide, e.g. to give the vacuum cleaner a nice shape pattern and / or to prevent damage to the joints 22A and 22B. FIG. 2 shows a section through the vacuum cleaner 10 according to the line II-II in FIG. 1. The cover 20A covers the chamber 24A and is connected to the housing 12 via the joint 22A. The hinge 22A comprises a first hinge part which is formed by the cover 24A on the one hand and by a socket 26A on the other hand. In joint socket 26A a hinge axis 32 of a second joint part 3OA superimposed. The second joint part 3OA is releasably connected to cover 2OA.

Fig. 3 shows cover 2OA and the second hinge part 3OA in the separated state and detached from the vacuum cleaner 10. The second hinge part 3OA is formed as a hollow body and has a hinge axis 32 which connects two male lugs 34 and 36 together. To form a plug connection with the plug projections 34 and 36 are located on the lid 2OA two mating plug 38 and 40, which can form a latching plug connection with the plug projections 34 and 36. For this purpose, the plug-in lugs 34 and 36 in the region of the plug-in engagement teeth 42 and 44. Each associated openings for receiving the latching teeth 42 and 44 are provided in counter-plug approaches 38 and 40.

Fig. 4 shows a section through the cover 2OA and the second hinge part 3OA in the region of the plug projections 34 and 36 and mating projections 38 and 40 as shown in FIG. 3. For plug projection 34 and mating socket 38, the opening 46 and the latching tooth 42 can be seen in section whereas the opening 48 and latching tooth 44 for the combination of the tab 36 and the mating tab 40 are not shown in section as the orientation of the opening 48 and the latching tooth 44 with respect to the alignment of the combination of the male tab 34 and the mating tab 38 by 90 ° is turned.

Fig. 5 and Fig. 6 show the lid 2OA and the second hinge part 3OA in the assembled state in a perspective view and in section through the insertion projections 34 and 36 and the Gegensteckansätze 38 and 40. The mating projections 34 and 36 extend into the mating plug approaches 38 and 40th into, and the latching teeth 42 and 44 are hooked into the openings 46 and 48.

A release of the two parts, ie, a separation, can be done only by moving eintlang the common axis (in Fig. 5 along the Z direction). In this case, however, the detachment of the cover 2OA can be triggered by force in different directions. If, for example, a force acts in the XY plane, plug-in extension 34 can deform with a correspondingly elastic choice of material in such a manner that the engagement of latching tooth 42 is released and the detachment process, ie also the disengagement of latching tooth 40, is triggered. The different arrangement and orientation of the latching teeth 42 and 44 makes it possible to define a directional characteristic for the load capacity of the lid from different directions. Fig. 7 shows a modified embodiment of a snap-in connector between a cover and a second hinge part. An insertion projection 70 of a lid has an annular notch 74. In the connected state, the plug-in lug 70 is releasably connected to a mating projection 72 of the second hinge part. The mating projection 72 in this case has an inwardly directed annular projection 76 of a ring 78, which protrudes in the inserted state into the annular notch 74 and slips out of the notch 74 only after a certain force. The force required for the release process is determined inter alia by the elasticity of the ring 78. Fig. 8 shows a further plug-in connection with a plug neck 80 and formed by a prestressed resilient cuff mating neck 82. The spring force of the cuff on the surface of the plug neck 80 causes dissolving a connected to the mating plug 82 lid only from a certain force dissolves , A directional characteristic of Kraftein rate may result, for example, by an asymmetric spring force of the cuff or a non-rotationally symmetrical design of the cuff. Further, for example, the materials of the male lug 80 and the mating male lug 82 may be selected to determine stiction. Fig. 9 shows a magnetic connector with a plug neck 90 and a mating tab 92, which are each provided with a magnet 94 and 96 respectively. Depending on the magnitude of the present magnetic force, a predetermined force is necessary to release the magnetic connector. An asymmetrically formed rim 98 may further provide an asymmetrical directional characteristic of the force required to disengage the connection.

With the vacuum cleaner according to the invention and the lid according to the invention advantageously damage to the vacuum cleaner can be counteracted by incorrect operation. In addition, the replacement of a damaged lid can facilitate.

The features disclosed in the preceding description, the following claims and the drawings can be used individually or in any combination for the Realization of the invention in its various embodiments of importance.
