Definitions
- the present invention relates to vacuum cleaners at least comprising a dust chamber, and connected to the dust chamber through a flow channel fan chamber, wherein the flow channel is at least partially formed as Heilleittrichter, and the Heilleittrichter in the direction of flow from its inlet opening, which is directed towards the dust chamber to to its outlet opening, which is directed towards the fan chamber, tapers in cross-section, and in the flow channel a Eingreifologygitter is arranged.
- Vacuum cleaners are electrical energy powered devices for picking up dust, including both mains powered and battery or rechargeable battery packs.
- the direction of flow is the direction in which the suction air flows during normal operation of the vacuum cleaner.
- the Heilleittrichter is the part of the flow channel, which has a taper and which is bounded by an inlet and an outlet opening.
- an opening is to be understood as meaning the opening, from which the cross-section of the flow channel first tapers in the direction of flow.
- An outlet opening is to be understood as meaning the opening, up to which the cross-section of the flow channel in the direction of flow tapers for the last time.
- the German patent DE 101 48 509 B4 is known in which a vacuum cleaner is disclosed with at least one collecting chamber and a receiving chamber for a suction agent.
- the collecting chamber and the receiving chamber are separated from each other by a partition which has an air guide funnel tapering in the direction of a suction means.
- the Heilleittrichter has in its funnel base a dome-shaped or otherwise shaped Eingreiftikelement which protrudes in the direction of the collection chamber.
- the mesh guard avoids the risk of injury from rotating fan blades.
- a relatively small obstruction of the air flow is achieved by the special funnel shape.
- the document US 3,454,978 is further known, in which an electric vacuum cleaner is disclosed which has a dust chamber within the main part.
- the dust chamber is partitioned from the interior of the main body by a partition having a tubular spout with a dust filter.
- the invention has for its object to provide a comparison with the prior art improved vacuum cleaner.
- a vacuum cleaner is to be provided with an intervention protection, which, taking into account the relevant statutory provisions, can prevent the user from interfering with the blower between the dust chamber and the blower compartment.
- an additional space e.g. Can accommodate filter materials can be provided between the dust chamber and the fan room.
- the vacuum cleaner according to the invention is based on generic vacuum cleaners on the fact that the protective mesh begins in the flow direction at the earliest in the last eighth of the tapered cross section of the Lucasleittrichters.
- the last eighth of the air guide funnel is to be understood as the space bounded by the outlet opening, the interior surfaces of the air guide funnel and a minimum surface, the minimum surface being defined by a surface delimiting line formed by the parting points on which the last legs of in start eight equally long sections divided shortest links.
- Below a minimal area spanned by a surface delineation line the area of all areas with the smallest surface area that contain the area delineation line is to be understood.
- the shortest links are routes, each one represent a shortest connection along the inner surface of the Lucasleittrichters in the flow direction from the inlet opening to the outlet opening, and which are subdivided into eight equal length sections, wherein the last section starts at a partial point and ends at the outlet opening.
- the invention may be suitable for vacuum cleaners where, according to the pertinent legal provisions, an intervention safety grille is necessary to reliably prevent the user's intervention in the fan and thus prevent injuries due to rotating fan blades. In addition, such a touch of electrical connections or live parts of the engine can be avoided. In this case, the design of the grid must pay particular attention to the statutory provision. For the Eingreifschutzgitter invention results from the statutory provisions a minimum height of the Eingreiftikgitters to meet the mechanical and electrical requirements safely.
- this additional space can be provided with a constant length of the vacuum cleaner and constant volume of space of the dust chamber and the fan room.
- the additional space can also be used to reduce the overall length of the vacuum cleaner, e.g. the additional space is used as a dust room.
- At least one additional material is arranged in the air guide funnel.
- a supplementary material is meant an air-permeable material that can absorb particles, eg dust, moisture or odors, and / or can release particles.
- the additional material is a filter material.
- the additional material of the suction air can remove dust, moisture and / or odors.
- a filter medium and / or an odorant is arranged in the air guide funnel.
- the additional material contains odor-neutralizing and / or odor-masking substances, which are particularly preferably dispensed.
- the odor-neutralizing and / or odor-masking substances are delivered to a suction air stream which can be generated by an engine-blower unit arranged in the blower compartment.
- the motor-blower unit may have an electric drive, for example an electric motor and / or fan blades.
- the suction air flows during normal operation of the vacuum cleaner in the flow direction of a dust receiving means, eg from a nozzle through a Saugluft arrangement, the dust chamber, the flow channel and the fan chamber up to a blowout on the vacuum cleaner housing.
- the additional material contains cage compounds, so-called clathrates.
- the active ingredient with ethereal essences in a vegetable-derived gel merged.
- the inclusion compounds and the clathrates are odor-neutralizing substances, since odor particles can be incorporated into the cavities of the inclusion compound and / or the clathrates. In this way it can be achieved that the odor particles are no longer perceptible, although they are still present in the air, enclosed by the inclusion compound and / or the clathrates.
- the additional material is arranged in layers and / or in a cassette in the air guide funnel.
- the fact that the additional material is arranged in different layers different of the stated filter functionalities can be combined.

- the retaining rib can be achieved that the hopper and / or the grid is stabilized.
- the additional material can be fixed in its position in the air-guiding funnel by the retaining rib. Since the retaining rib does not take over intervention protection in the blower and in this sense is not part of the lattice, the legal safety regulations in the design of the retaining rib need not be taken into account.
- the retaining rib is designed as a pin in the middle of the air guide funnel and / or as a thin web on the inner wall of the air guide funnel.
- the retaining rib is thereby particularly suitable for fixing and / or positioning a cassette in which e.g. An additional material can be arranged.
