Description

Field of the invention

The present invention relates to a vacuum cleaner with a first housing part, a movable second housing part and a filter carrier for receiving a Staubabscheideeinheit, wherein the filter carrier is movably connected via a filter carrier bearing with the first housing part, and the filter carrier can be in a blocking position with removed Staubabscheideeinheit, in which he prevents closing of the second housing part.

Background of the invention

For example, from the German patent application DE 10163525 A1 a filter lock for a vacuum cleaner known. The filter lock has a pivoting lever, and can only be brought into a release the function of the vacuum cleaner stop position when the pivot lever is actuated or pressed by a shoulder of a stiffening plate of a dust bag inserted.

Next is from the German patent application DE 10 2004 040 981 A1 a vacuum cleaner with a housing known. The housing has a dust chamber, in which a dust collecting device is used, which is held by means of a movably mounted between a rest position and an operating position carrier. Next, the vacuum cleaner has a pivotally mounted dust chamber lid. The carrier has a spring element with a free end, which is supported on a wall portion of the housing. By the spring element, a restoring force is exerted on the carrier, which tries to return the carrier to the rest position when no dust collecting device is inserted into the carrier. In order to prevent a closing of the dust chamber cover in the absence of dust collecting device, a shoulder is integrally formed on the carrier, against which a housing edge of the dust chamber cover abutting. The carrier thus forms a barrier for the dust chamber cover, so that the dust chamber cover can not be closed in the absence of dust collection device.

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 vacuum cleaner with a filter support to be provided, in which the filter support can enable a stable filter lock. Next, the filter carrier of the vacuum cleaner should be able to signal a missing Staubabscheideeinheit easily recognizable.

The solution of the problem is achieved by a vacuum cleaner with the features of claim 1.

Vacuum cleaners are electrical energy powered devices for receiving dust, including both mains powered and battery or cordless tools. A vacuum cleaner can z. B. comprise a motor-blower unit for generating a suction air flow. Under a Staubabscheideeinheit is a means for retaining and / or collecting dust z. B. from the suction air flow. The Staubabscheideeinheit can z. B. be designed as a dust bag, filter or cyclone. When closing the second housing part, the second housing part is brought from an open position to a closed position, wherein the second housing part from the open to the closed position passes through a path of movement. When closed, the second housing part closed to a maximum of 50% has traveled a maximum of 50% of the movement path starting from the open position. So z. B. a rotatably mounted second housing part to a maximum of 50% closed when the opening angle of the second housing part in the locked position is at least 50% of the opening angle at maximum opening.

It is an achievable advantage of in the blocking position of the filter support to a maximum of 50% closed second housing part that upon exposure of a force on the second housing part, the filter support bearing can be relieved. Because with a maximum of 50% closed second housing part acting on the filter support bearing force can be minimized due to the law of levers. Advantageously, it is therefore achievable that the effective distance between the force applied to the second housing part and the force acting on the filter support bearing counterforce can be minimized. The effective distance here is perpendicular to the parallel forces directed to each other (force, drag).

It is another achievable advantage of the second housing part, which is closed when the filter support is in the locked position to a maximum of 50%, that an easily recognizable signaling of a missing dust removal unit can be achieved. This can be advantageously avoided that the user takes the vacuum cleaner without Staubabscheideeinheit in operation. Advantageously, it can be achieved that a user only has a second closed to a maximum of 50% Housing part that can not close, immediately noticeable. In this way it can be avoided that the user overlooks that the second housing part can not be closed, and he therefore tries in spite of the filter carrier in the locked position to close the second housing part. Advantageously, such a damage of the filter support and / or the filter support bearing can be avoided.

It is an achievable advantage of the first support point of the filter support, which contacts the first housing part at a first support point in the blocking position, that the filter support bearing can be relieved in a filter support in the blocking position. For in the filter carrier in the blocking position, a force acting on the filter carrier force on the first support point and the first support point are transmitted to the first housing part, whereby advantageously acting on the filter support bearing force can be reduced. In this way, a stable and / or durable filter carrier can be made possible, which can reliably prevent the closing of the second housing part when the dust separation unit is removed in a blocking position. Further, upon exposure to a force on the second housing part, for. B. due to the attempt of a user to bring the second housing part in spite of the filter carrier in the locked position, a reduction of the forces acting on the filter carrier bearing forces are made possible. This can advantageously prevent damage to the filter carrier and / or the filter carrier bearing.
