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.
  • US 2017/290479 A1 and the EP 2 581 012 A1 disclose a hand-held vacuum cleaner with a third filter stage which is arranged between the separator container and the drive unit container.
  • the WO 2008/070965 A1 and WO 2020/168417 A1 reveal vacuum cleaners with a third filter stage in the drive unit container.
  • WO 2019/164257 A1 discloses a vacuum cleaner with a first and second filter stage in the separator container.
  • 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 to allow cleaning.
  • the advantages that can be achieved with the invention include the realization of several filter stages in a compact installation space and the fact that a separation vessel with high separation efficiency is realized in a compact installation space. In addition, all filter stages that need to be cleaned are easily accessible for the user.
  • the second and third filter stages By structurally separating the second and third filter stages, a higher degree of particle separation is achieved in the filter stages. Overall, an improved separation performance of the second and third filter stages is achieved. This minimizes the effort required to clean the filter stages and at the same time increases the maintenance intervals of the filter stages.
  • the structurally separate arrangement of the second and third filter stages ensures greater stability and tightness between components. This means that the vacuum cleaner is designed as a relatively small and compact device.
  • the first filter stage and the second filter stage can provide the separation container as a finer, sharp separator, since the third filter stage is located outside the separation container.
  • the vacuum cleaner preferably also has a handle.
  • the handle is preferably firmly connected to the drive unit container or can be connected.
  • the fact that the three filter stages are arranged one behind the other in the specified order in terms of flow means that the suction flow generated first passes through the first filter stage, then the second filter stage and finally the third filter stage.
  • cyclone vacuum cleaner refers to a vacuum cleaner that is bagless and in which eddies and possible turbulences are generated in an air stream entering the vacuum cleaner, whereby the suction material, such as dust particles, is pressed in a predetermined direction and separated due to centrifugal force.
  • bagless is to be understood as meaning that the suction material in the vacuum cleaner is collected directly in the separating container without a bag or similar replaceable filter medium being arranged in it to hold suction material, so that the user does not remove a bag or similar from the separating container to empty the suction material from the separating container.
  • the vacuum cleaner has several filter media that prevent suction material from reaching the drive unit arranged in the drive unit container.
  • operation refers to the cleaning operation of the vacuum cleaner.
  • the drive unit of the vacuum cleaner generates a suction current.
  • the drive unit is supplied with electrical energy by the vacuum cleaner's batteries. Using the suction current generated, the vacuum cleaner can absorb, separate and store dust and dirt particles.
  • the phrase "arranged axially to the longitudinal axis of the drive unit container" means that the central filter extends along a portion of the longitudinal axis of the drive unit container and is aligned with respect to the longitudinal axis.
  • the longitudinal axis of the suction pipe forms the center of the suction pipe cross-section and runs along the entire length of the suction pipe.
  • the longitudinal axis of the suction pipe is arranged parallel to the longitudinal axis of the separating container in the vacuum cleaner according to the invention. This parallel arrangement of the longitudinal axes of the suction pipe and separating container is given when the suction pipe and the separating container are arranged on the vacuum cleaner in a configuration ready for cleaning.
  • the vacuum cleaner further comprises an inlet slot which is arranged such that during operation the suction flow from the inlet slot is directed tangentially to an inner wall of the separating container, 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 first filter stage preferably comprises the inlet slot, the inner wall and a dip tube.
  • the dip tube is an integral part of the separating container and extends from one side into the interior of the separating container.
  • the inlet slot preferably has a rectangular cross-section.
  • the vacuum cleaner preferably has a suction pipe from which the suction flow flows into the inlet slot during operation.
  • the suction pipe preferably has a circular cross-section.
  • the suction pipe can preferably be connected to a floor nozzle and/or an extension pipe.
  • the pre-filter is preferably made of a fabric gauze, a plastic sieve, a punched grid or a metal gauze.
  • the second filter stage preferably also has an inner tube which is connected to the pre-filter.
  • the inner tube is preferably arranged behind the pre-filter and before the third filter stage in terms of flow.
  • the pre-filter is preferably 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 an outer housing of the drive unit container.
  • 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 central filter is a hollow cylindrical filter, wherein the central filter forms an outer surface and an inner surface.
  • the central filter has a pleated shape.
  • the drive unit container, the separator container and/or the drive unit are aligned along parallel longitudinal axes.
  • the pre-filter and the central filter are also aligned parallel to the longitudinal axes. All longitudinal axes are therefore aligned in one spatial direction.
  • the vacuum cleaner has a fourth filter stage, which is arranged fluidically after the third filter stage.
  • the fourth filter stage preferably has an exhaust air filter element.
  • the exhaust air filter element is preferably designed as a filter or a flap in a drive unit container outer housing.
  • the drive unit container preferably has a drive unit housing which surrounds the drive unit and is surrounded by a flow cross-section through which the suction flow flows during operation before it reaches the third filter stage.
  • the flow cross-section is preferably circular. This means that the vacuum cleaner remains compact. However, the circular flow cross-section can be partially interrupted by functional geometry(s).
  • the drive unit housing, the flow cross-section and the central filter are preferably designed and arranged such that the suction flow flows circumferentially around the third filter stage during operation.
  • the second filter stage can be removed from the separating tank in a removal direction that is opposite to another removal direction in which the third filter stage can be removed from the drive unit tank. 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 separating tank by removing the dip tube.
  • This removal option also has the advantage that the separating tank and the drive unit tank can be permanently connected to one another. Preferably, they are permanently connected to one another and designed as a separating unit.
  • the suction flow generated during operation flows around the outer surface of the central filter.
  • the flow around the central filter enables good separation performance and a relatively long service life of the central filter.
  • the central filter is designed and arranged in such a way that the suction flow generated during operation flows axially from the inner surface of the central filter into the drive unit. This means that the vacuum cleaner is still provided in a compact manner.
  • a suction pipe diameter of the suction pipe is substantially equal to a cross-sectional area of the inlet slot with a rectangular cross-section.
  • the suction pipe diameter is substantially equal to a filter stage diameter of the inner pipe of the second filter stage and/or equal to a diameter of the pre-filter.
  • An area of the flow cross-section between the drive unit housing and the drive unit container outer housing is preferably approximately equal to the area of the suction pipe diameter.
  • the diameters refer in particular to inner diameters.
  • the diameter of the suction pipe is preferably in the range of 20 to 40 mm, preferably 25 to 35 mm.
  • the first filter stage preferably has the following dimensions: More preferably, the cyclone has a diameter in the range of 90 to 100 mm, a height of the cyclone, which is defined as a dimension between the inlet slot and the inner wall, is preferably in the range of 80 to 140 mm, preferably 110 to 130 mm.
  • a height of the dip tube, which represents a longitudinal extension of the dip tube starting from the inner wall, is preferably in the range of 20 - 60 mm, more preferably 30 to 50 mm, and a diameter of the dip tube is preferably 35 - 60 mm, more preferably 40 to 50 mm.
  • a width of the inlet slot is preferably 14 - 30 mm, preferably 18 to 26, while a height of the inlet slot is preferably 20 - 52 mm, preferably 30 to 40 mm, wherein the height and width of the inlet slot define a cross-section of the inlet slot.
  • the vacuum cleaner is preferably a battery-operated vacuum cleaner. This means that the vacuum cleaner has a battery and is designed to be operated using the battery as a power source.
  • the battery can be connected to the separator container and/or the drive unit container.
  • the drive unit container is connected to the handle.
  • the drive unit container is preferably located at the back or rear end of the vacuum cleaner, which means that it is closer to the user's hand and further away from the surface to be vacuumed than the separation container.

  • the drive unit 5 During operation, the drive unit 5 generates a suction flow, which is partially indicated by the arrows.
  • the suction flow passes through the first filter stage 6, where it impacts on the inner wall 10 and a cyclone is formed.
