Description

The invention relates to a Zyklonabscheidstaubsaugerwelchts which allows a proper Staubsaugebetrieb in a suction position.

Such vacuum cleaners are known from the prior art. These are so-called bagless dust cleaners. Instead of a conventional vacuum cleaner bag, a cyclone separator is used. In this, the air containing the dust to be collected flows into a separation space. The air whirls the dust in the circumferential direction along the inner surface of the substantially conical separation space. The separation chamber tapers in the direction of the air outlet, so that the air flowing through such a separator and in particular the dust particles contained therein are accelerated as a result of the centrifugal force. At the air outlet of such a separator, the dust particles are thrown into a dust collecting space.

The dust collector used in a generic vacuum cleaner can either comprise only the dust collector or a combined unit of a collecting container on the one hand and the separator, in particular cyclone, on the other. In any case, the dust collector must be emptied regularly to dispose of the collected dust particles.

For the purpose of emptying, it is customary to remove the Staubabscheidebehälter from the operating position on the vacuum cleaner body. For the arrangement and removal of the Staubabscheidebehälters various ways are known in the art. According to a first possibility, the dust collecting container is arranged in the interior of the vacuum cleaner body, so that it is not accessible in the suction position, ie when the vacuum cleaner is used as intended during a vacuuming operation. In order to access it, rather, the suction position must be left by turning off the vacuum cleaner fan and unfolding a housing part of the vacuum cleaner body, which locks in the closed state, the Staubabscheidebehälter in the operating position.

According to a second possibility, the dust collecting container is locked in the intended use with the vacuum cleaner body. To be able to separate the dust collector from the vacuum cleaner body, both parts must first be unlocked. For this purpose, it is known, for example, to provide a push button on the vacuum cleaner body or the Staubabscheidebehälter itself, with which a lock releasing mechanism can be operated.

The known possibilities for emptying the Staubabscheidebehälters are not free of disadvantages. First, the handling is relatively complex, since not only the Staubabscheidebehälter itself must be handled, but in addition further handles for opening the vacuum cleaner body, for pressing the push buttons and / or the like are required. On the other hand, many generic vacuum cleaners have the necessity that the vacuum cleaner must first be transferred from a position for the intended use to a position for removing the dust collecting container. The Staubsaugebetrieb must therefore be laboriously interrupted and it is equal to several additional handling steps required.

Based on this prior art, it is the object of the present invention to simplify the handling of a generic vacuum cleaner, in particular with regard to emptying the Staubabscheidebehälters.

To solve the invention proposes in front of a Zyklonabscheidstaubsauger, which allows in a suction position a proper Staubsaugebetrieb with a vacuum cleaner body and a can be arranged in an operating position on the vacuum cleaner body Staubabscheidebehälter which has a container housing and a carrying handle, wherein the Staubabscheidebehälter in the operating position on the vacuum cleaner body in five directions of movement held positively and in a sixth, the removal of the vacuum cleaner body serving direction of movement is held exclusively non-positively, the dust collecting container remains accessible in the suction position from the outside

According to the invention, the carrying handle of the Staubabscheidebehälester located in the operating position remains accessible from the outside during the intended use of the vacuum cleaner, and the Staubabscheidebehälter is alone by Pull on the handle formed from the operating position removable.

The six directions of movement are in each case both directions of the three orthogonal, a Staubabscheidebehälterfestes reference system spanning axes. In five of these directions, the Staubabscheidebehälter is held by positive locking secured to the vacuum cleaner body. In the sixth direction of movement, however, only a frictional connection is provided. This movement direction is the removal direction in which the dust collection container can be arranged on the vacuum cleaner body and removed therefrom. The exclusive provision of a frictional connection causes the dust collecting container can be moved in this direction relative to the vacuum cleaner body without prior separation of a positive connection or the like. All that needs to be overcome is an opposing force resulting from the adhesion. The frictional connection can be generated, for example, by means of two parts of the dust collecting container and the vacuum cleaner body in contact with a defined coefficient of friction.

The invention thus delimits itself with two synergistically co-operating features of the prior art. On the one hand, the invention provides that the handle of the Staubabscheidebehälters always remains accessible from the outside in the suction position. Vacuum position here means a configuration of the vacuum cleaner, in any time by switching on the vacuum cleaner suction would be possible without additional handle would be required to close the vacuum cleaner body or the like. This means inter alia that the carrying handle forms part of the visible or tangible outer surface of the vacuum cleaner itself. In contrast to the possibility known from the prior art to embed the dust collecting container completely inside the vacuum cleaner body, the dust collecting container is not accommodated in the interior of the housing, but rather protrudes at least partially from the vacuum cleaner body.

On the other hand, the invention proposes that the dust collector can be separated waiving controls such as push buttons for actuating a release mechanism. A detachment or removal of the Staubabscheidebehälters from the operating position is carried out exclusively by mere pulling on the handle. The dust collecting container is preferably at least movable in a direction perpendicular to the direction of travel relative to the vacuum cleaner body.

The Staubabscheidebehälter may be performed on the vacuum cleaner body. It may in particular be a linear guide. The vacuum cleaner body preferably has a stop on which the dust collecting container abuts when it is inserted into the vacuum cleaner body upon reaching the operating position.

The concept according to the invention is characterized, among other things, by its particular simplicity. This simplicity makes at the same time the special feature of the invention. Namely, the invention avoids the prejudice prevailing in the prior art that a complex mechanical positive locking of the dust collecting container in the operating position is required, which requires extensive measures such as opening a flap of the vacuum cleaner body or a push-button-operated mechanism for releasing.

The solution according to the invention, in contrast, brings a significantly simplified handling with it. The removal or removal of the Staubabscheidebehälters from the operating position is possible with only a single handle. At the same time it can be provided that the removal or release of the Staubabscheidebehälters takes place in one and the same suction position, which occupies the vacuum cleaner even when used as intended. The vacuum cleaner must therefore not be transferred to another position, for example, set up, turned over and / or the like. The simplicity of handling achieved by the invention is particularly advantageous for emptying the dust collector. A person using the vacuum cleaner according to the invention needs only to turn off the vacuum cleaner, then removes the Staubabscheidebehälter with one hand, empties it and then sets it again (also with just one hand) in the vacuum cleaner body. The entire process can therefore be carried out in principle with one hand. This allows the user, for example, to hold the vacuum cleaner brush in the other hand throughout the process.

According to an advantageous embodiment of the invention, the carrying handle is displaceably guided in the container housing, wherein the carrying handle between an inserted into the container housing and a retracted from the container housing configuration is movable, wherein the Staubabscheidebehälter alone by pulling and then continued pulling movement of the handle from the operating position is designed removable. The carrying handle can be guided linearly in the container housing. The carrying handle may be U-shaped, wherein the two parallel legs of the U are guided in the container housing and the web connecting the two legs forms the actual handle. In this way, a particularly robust embodiment of the carrying handle is achieved, which at the same time has a special aesthetic appearance. In addition, such a carrying handle does not rattle, for example, as in the region of an end face of a Staubabscheidebehälters rotatably mounted by 180 ° handle, which rests only loosely on the end face in a rest position.

According to an advantageous embodiment of the invention, the Staubabscheidebehälter locked in the operating position with the vacuum cleaner body. This locking ensures that the dust collector is held particularly safe in the operating position, that is, for example, not only because of its weight. Locking means in particular a frictional connection. The latching connection is designed to be re-drivable, so that the latching can be achieved solely by pulling on the carrying handle of the dust-collecting container. As a result, the previously described simple handling while achieving increased reliability is achieved overall.

The latching connection can be formed in that the Staubabscheidebehälter a resilient latching tongue and the vacuum cleaner body have a corresponding receptacle for the latching tongue. The kinematic reversal of both parts is possible. In the operating position, the latching tongue is accommodated in the receptacle. This connection between the two parts provides primarily for a frictional connection, which keeps the dust collecting container in the operating position. The receptacle and / or the latching tongue may have an inlet slope, so that both parts slide slightly in the direction of insertion. Preferably, the latching connection is designed drivable by pulling movement on the handle, that the holding force or frictional force to be overcome is less than the weight of the vacuum cleaner. In this way, it is ensured that, for example by jerky pulling on the handle does not lift the vacuum cleaner from the ground, but always takes only a removal of Staubabscheidebehälters.

According to an advantageous embodiment of the invention, the vacuum cleaner body is at least also perpendicular to the direction of travel of the vacuum cleaner extending hook for receiving the Staubabscheidebehälters on. Consequently, the hook is formed such that the dust collecting container can be attached to it and remains in the operating position due to its weight. The hook thus holds the dust collecting container in one to five possible directions of movement, depending on the design of the corresponding counterpart on the dust collecting container. An alternative or additional determination of the Staubabscheidebehälters in the operating position can be achieved by the design of the corresponding receptacle of the vacuum cleaner body. The vacuum cleaner body can give the dust collector, for example, lateral support. It can also be provided that the hook is designed such that the dust collecting container is also held in a carrying position of the vacuum cleaner, in particular hangs on the hook. In the carrying position of the vacuum cleaner is usually held with its longitudinal axis perpendicular to the ground, wherein the longitudinal axis otherwise runs parallel to the ground in the operating position in the direction of travel. It can also be provided a plurality of hooks, for example, two or three. The hook thus serves a particularly secure arrangement of the Staubabscheidebehälters in the operating position.

In addition, it can be provided that the hook or hooks have an insertion bevel at their tip. The tip may be conical or polygonal. It is crucial that the hook tapers in the area of the tip in the direction of the tip. In this way, certain positional tolerances can be compensated when the dust collecting container is inserted and the dust collecting container is guided along the insertion bevel into the intended operating position.

In particular, in combination with the latching connection already described above can be provided that the hook has a receptacle for the latching tongue of Staubabscheidebehälters. The hook can thus fulfill a dual function, that is, on the one hand to ensure the position of the Staubabscheidebehälters position in the operating position and on the other hand provide for the formation of the optionally desired locking connection.

According to an advantageous embodiment of the invention, the carrying handle has at least one leg, with which it is guided in a receptacle in Staubabscheidebehälter, wherein the leg has a thickening at its free end. If several legs are provided, all thighs can be such a thickening at their free Have end, for example, in the previously described U-shape of the handle. The free end of the legs is opposite the handle of the carrying handle. The thickening may be formed such that its cross section is not aligned with the cross section of the receptacle. The thickening of the thighs in other words does not fit through the receptacle. As a result, a mechanical stop is created, which defines a maximum possible excerpt of the carrying handle. At the same time a safe power transmission can be ensured in the handling of Staubabscheidebehälters, so that a user by grasping the carrying handle alone can safely carry the entire weight of the Staubabscheidebehälters with any dust particles contained.

According to an advantageous embodiment of the invention, the thickening is conical, wherein the receptacle in the dust collecting container has a conically tapered stop for the extended from the container housing handle. The thickening on the leg is in particular designed such that the leg tapers from its free end, starting in the direction of the handle. The stop in the receptacle is designed to correspond. He tapers in the extension direction of the handle. If the carrying handle is fully extended, the two conical surfaces come into contact. This will easily jam them together. In this way, a very firm and play-free arrangement of the handle is achieved in the extended position.

The FIG. 1 shows an embodiment of a vacuum cleaner 1 according to the invention in plan view. The vacuum cleaner 1 has a vacuum cleaner body 2, in which a Staubabscheidebehälter 3 is inserted. The Staubabscheidebehälter 3 is present in the suction position. In this, the vacuum cleaner housing 2 is closed and it would be possible at any time by switching on and without further action a suction operation. The Staubabscheidebehälter 3 has a container housing 4 on the one hand and a carrying handle 5 on the other.

The vacuum cleaner 1 further has a connection 17 for a hose, for example for connection to a floor nozzle. In addition, the vacuum cleaner 1 has a front handle 13, with which it can be moved and carried.

FIG. 2 shows a corresponding side view of the vacuum cleaner 1. He is in the suction position for intended use. He stands on a ground 14 and can be moved over this. For this purpose it has unillustrated rollers.

It is noteworthy that the Staubabscheidebehälter 3 is accessible in the suction position from the outside. In particular, the carrying handle 5 is accessible from the outside. The Staubabscheidebehälter 3 is thus not completely housed in the interior of the vacuum cleaner body 2. The dust collecting container 3 is held in the operating position, inter alia due to its weight. In addition, the Staubabscheidebehälter 3 in five directions of movement 15, 16, 18 held positively on the vacuum cleaner body 2. From the into the FIGS. 1 and 2 As shown configuration, the dust collecting container 3 at any time by pulling on the handle 5 in a sixth direction of movement 19 are removed from the operating position, for example, to empty it.

The FIGS. 3 and 4 show a lateral cross-section through the vacuum cleaner 1. Zu see is a section which shows the container housing 4 of the Staubabscheidebehälters 3 substantially. The carrying handle 5 has a leg 10. This extends at right angles to the actual handle. The leg 10 is guided linearly movable in a receptacle of the container housing 4. In this way, the carrying handle 5 can be pulled out of the container housing 4 in the sixth direction of movement 19 and inserted into the direction of movement 18 in this. In the in FIG. 3 shown position, the carrying handle 5 is completely inserted into the container housing 4. Noteworthy among other things, the aesthetic appearance, since the handle 5 merges seamlessly into the remaining surface of the vacuum cleaner 1 substantially.

In the present case, the leg 10 has a thickening 11 at its free end. This is in the present case conical. The receptacle for the leg 10 has a stop 12. This is located at the top of the recording. He is also conical, preferably in accordance with the thickening 11. In the in FIG. 4 shown extended position of the handle 5 beats the thickening 11 on stop 12 at. While the carrying handle 5 outside the contact of the two stops with each other can be moved comparatively easily and almost contactless in the recording, now makes a flat contact. The carrying handle 5, that is, the thickening 11 easily jammed in the receptacle. As a result, the carrying handle 5 is held in this end position particularly safe and free of play.

The Figures 5 and 6 show a detail of the contact between the Staubabscheidebehälter 3 and the vacuum cleaner body 2. On the container housing 4, a latching tongue 6 is arranged. This is resilient in the direction of travel 16. On the vacuum cleaner body 2, in turn, a hook 8 is provided. The Staubabscheidebehälter 3 can be plugged onto the hook 8. To facilitate this, the hook has an insertion bevel 9.

If the dust collecting container 3 is inserted into the operating position, the resilient latching tongue 6 jumps into a receptacle 7 provided on the hook 8. This is a projection which ensures an undercut of the hook 8 through the latching nose 6 in the removal direction of the dust collecting container 3. If the dust collecting container 3 are removed from the operating position, the frictional force or holding force acting through the contact between the latching tongue 6 and the hook 8 must be overcome. This frictional force or Holding force thus ensures a certain securing position of the Staubabscheidebehälters 3 in the operating position. However, the frictional force or holding force is lower, in particular significantly lower than the weight of the vacuum cleaner, so that a pull on the handle 5 can not cause the vacuum cleaner 1 lifts off the ground 14.

The figures can further be seen that the carrying handle 5 in the inserted state is flush with the surface of the Staubabscheidebehälters 3. The carrying handle 5 can be accessible via a molded into the surface recessed grip. In this way, the vacuum cleaner 1 has a uniform design.

The Staubabscheidebehälter 3, in particular the container housing 4 has on the vacuum cleaner body 2 side facing each right and left an opening, for example in the form of a slot. In these openings, the hook 8 dives. The hook 8 may be part of a cover of the vacuum cleaner 1. The hook 8 is designed such that the dust collecting container 3 is secured in both directions of movement 16 along the longitudinal axis of the vacuum cleaner 1 in its position. In addition, the Staubabscheidebehälter depends in the driving position on the hook 8. In the transverse direction of movement 15 of the vacuum cleaner 1 movement of the Staubabscheidebehälters 3 is blocked by a corresponding geometry of the vacuum cleaner body 2. In the carrying position, that is, when the vacuum cleaner 1 is perpendicular with its longitudinal axis on the substrate 14, the Staubabscheidebehälter 3 depends on the hook or 8. It is thus only the sixth direction of movement 19 released at all for movement.

In addition, the hook 8 is geometrically designed so that the dust collecting container 3 can be inserted into the vacuum cleaner body 2 not only directly vertically, but also in a balanced position (which is suspended over the center of gravity). This is achieved inter alia by the previously described chamfers 9.

The receptacles of the container housing 4, in which the legs 10 of the carrying handle 5 are guided, may have spacer ribs. About the design of the spacer ribs, the game of the handle 5 can be defined in the recording. As a result, the behavior of the carrying handle 5 can be adjusted during the pull-out movement be, that is, in the phase in which the carrying handle 5 is not yet posted on the stop 12.

The conical thickening 11 may correspond to approximately one quarter of the entire length of the leg 10. This value has been found in experiments to be particularly advantageous. Due to the above-described embodiment of the carrying handle 5 with the thickening 11, it is necessary that the carrying handle 5 is mounted from below into the container housing 4 or an upper part of the container housing 4.
