Definitions
- the invention relates to a hand-held cyclone vacuum cleaner, which is referred to below as a vacuum cleaner for the sake of simplicity.
- the invention relates to a vacuum cleaner which has a separating container for receiving suction material and a drive unit container which has a drive unit which is designed to generate a suction air flow during operation.
- Such a vacuum cleaner is from the WO2017/046 559 A1 known.
- the vacuum cleaner has two filter stages, which are implemented using cyclone technology, so that they are designed as a multi-cyclone.
- the vacuum cleaner also has a third filter stage, which is connected downstream of the multi-cyclone in terms of flow technology and is built around an encapsulated radial fan. An axial outflow from the fan is directed through an exhaust air filter.
- the flow to the various filter stages requires a relatively large installation space.
- the US 2017/290479 A1 and EP 3 563 739 A1 reveal hand-held vacuum cleaners in which the filter elements in the separator can be removed in one direction.
- the WO 2019/231153 A1 , US2019/307304 A9 , US 2019/008340 A1 , WO 2019/231157 A1 , WO 2019/231157 A1 and EP 3 287 059 A1 reveal such vacuum cleaners.
- the invention therefore addresses the problem of providing a hand-held cyclone vacuum cleaner that has several filter stages that are implemented in a compact installation space.
- the filter stages should be accessible to the user.
- the invention provides a vacuum cleaner in a compact design that has several filter stages.
- the implementation of several filter stages enables a particularly effective separation unit with a particularly selective first filter stage.
- all filter stages of the separation unit that require periodic cleaning are arranged so that they are easily accessible for the user.
- the invention relates to a hand-held cyclone vacuum cleaner, comprising a separation unit for collecting suction material, which has a drive unit for generating a suction flow, a first filter stage, a second filter stage and a third filter stage; wherein the drive unit is arranged downstream of the second filter stage and upstream of the third filter stage in a drive unit housing, wherein the drive unit is surrounded by the suction flow generated during operation of the drive unit.
- the drive unit is arranged spatially between the second filter stage and the third filter stage in a drive unit housing.
- the term "hand-held" means that the vacuum cleaner is operated by hand by the user.
- the vacuum cleaner preferably also has a handle.
- the handle is preferably firmly connected to the separation unit or can be connected.
- cyclone vacuum cleaner refers to a vacuum cleaner that is bagless and in which the suction flow in the separation unit forms a vortex flow that functions to separate dust and dirt particles from the suction flow under the influence of gravity.
- the first filter stage of the separation unit of the cyclone vacuum cleaner forms a longitudinal axis, whereby when the drive unit is in operation, the suction flow forms a vortex flow around the longitudinal axis of the first filter stage, whereby the longitudinal axis of the first filter stage is aligned parallel to the longitudinal axis of the suction pipe.
- the parallel alignment of the longitudinal axes of the first filter stage and the suction pipe are crucial for the realization of a vacuum cleaner with a compact design.
- bagless means that the suction material in the vacuum cleaner is collected directly in the separation unit, without a bag or similar replaceable filter medium being arranged in the latter to collect suction material, so that the user does not remove a bag or similar from the separation container to empty the suction material from the separation unit.
- the vacuum cleaner has several filter media that prevent suction material from reaching the drive unit arranged in the drive unit housing.
- the drive unit is arranged such that an inflow direction of the suction flow into the drive unit is opposite to a flow direction of the suction flow from the second filter stage to the third filter stage.
- the generated suction flow therefore also changes its direction by 180° during its path within the vacuum cleaner.
- the drive unit which is preferably designed as a fan, is preferably rotated by 180° with respect to a suction pipe of the vacuum cleaner, into which the suction flow enters the vacuum cleaner before entering the three filter stages. This means that a The flow direction of the suction flow entering the intake manifold is opposite to another flow direction of the suction flow entering the drive unit.
- the first filter stage has a cyclone generated by the drive unit during operation
- the second filter stage has a pre-filter
- the third filter stage has a central filter.
- the central filter has a storage medium designed to store dust. It is preferably designed as a fine filter.
- the pre-filter essentially serves as filter protection for the central filter and is essentially designed to prevent coarse particles from entering a space between the second filter stage and the third filter stage.
- the pre-filter and the central filter are arranged axially along the longitudinal axis of the separation unit.
- the separation unit extends along a longitudinal axis.
- the pre-filter and the central filter each extend parallel to the longitudinal axis.
- the first filter stage, the second filter stage and the third filter stage are arranged one after the other in the specified order in terms of flow. This means that the suction flow generated first passes through the first filter stage, then the second filter stage and finally the third filter stage.
- the first filter stage further comprises an inlet slot which is arranged such that during operation the suction flow from the inlet slot is guided tangentially to an inner wall of the separating vessel, so that a cyclone forms in the first filter stage during operation.
- the cyclone vortex forms in the first filter stage during operation, so that particles are separated with a certain pressure loss and a certain separation grain.

- the pre-filter is arranged between the inner wall and the inner tube.
- the central filter is a cylindrical filter that is sealed to the drive unit and to a separating unit outer housing.
- the central filter preferably has a storage medium that is designed to store dust. It is preferably designed as a fine filter.
- the pre-filter essentially serves as filter protection for the central filter and is essentially designed to prevent coarse particles from entering a space between the second filter stage and the third filter stage.
- the third filter stage is arranged in such a way that the suction flow generated during operation flows axially into the drive unit. This enables a compact design of the vacuum cleaner.
- the second filter stage can be removed from the separation unit in a removal direction that is opposite to another removal direction in which the third filter stage can be removed from the separation unit. Due to the parallel arrangement of the second filter stage and the third filter stage, both can be removed independently of one another.
- the pre-filter is detachably connected to the inner wall of the first filter stage, which is connected to the dip tube, so that the second filter stage can be removed from the separation container by removing the dip tube.
- the vacuum cleaner further comprises a fourth filter stage, which is arranged fluidically behind the third filter stage and which comprises an exhaust air filter element.
- the exhaust air filter element is preferably designed as a filter or a flap in an outer housing of the separation unit.
