  • a cyclonic separator for a vacuum cleaner.
  • the cyclonic separator is for separating dust or dirt from dust-laden air and for use in a vacuum cleaner of the type having a motor mounted downstream of the suction inlet in the vacuum cleaner body.
  • the separator has a first end and a second end and includes an inlet to receive a flow of dirt-laden air and a separation chamber configured to receive dirty air from the inlet.
  • the separation chamber includes an airflow outlet provided in the separation chamber and configured to draw air through the outlet in a direction generally toward the first end of the separation unit, a screen disposed at the airflow outlet having a plurality of openings and configured to prevent large debris from passing through the airflow outlet, and a debris outlet defining an opening in a wall of the separation chamber.
  • the separation device includes a dirt collection chamber in communication with the dirt outlet and adapted to receive dirt separated from the dirty air; and a passage defining an air flow path from the air flow exit to an outlet of the separator in a direction substantially towards the second end of the separator such that in use the outlet of the separator is adapted to communicate with the suction inlet of the vacuum cleaner body to to draw dirty air into the separator.
  • the German release DE 11 2010 001 135 T5 discloses a surface cleaning device that includes a cyclone.
  • the housing wall facing the end of the cyclone is beveled in sections.
  • the US patent application U.S. 2014/0 237 759 A1 relates to a hand-held surface cleaning device, such as a cyclone handheld vacuum cleaner, with a duct communicating with the cyclone air outlet.
  • the conduit extends through the pre-motor filter and communicates with the upstream side of the pre-motor filter.
  • the international patent application WO 2014/ 195 711 A1 relates to a handheld vacuum cleaner.
  • the vacuum cleaner is expected to be particularly suitable for cleaning locations that are difficult to reach with a conventional vacuum cleaner.
  • the vacuum cleaner has a housing with a substantially planar base on which the vacuum cleaner can rest when not in use, the housing having a carrying handle, a motor and an impeller located within the housing, the vacuum cleaner also having a Comprising collection unit and a battery pack, wherein the battery pack makes up at least part of the base.
  • the motor and battery pack are located between the base and the collection unit to lower the center of gravity and make the vacuum cleaner more comfortable to use, especially over long periods of time.
  • the task at hand is achieved by providing a hand-held, battery-operated vacuum cleaner which has a suction opening and a motor/blower unit.
  • the motor-fan unit is designed to generate a suction air flow that extends from the suction opening via a dust separation device to the motor-fan unit.
  • the Dust separating device is designed to rotate air flowing in via an air inlet area about an axis of rotation.
  • the dust separating device is designed as a dust separating device that is closed at the bottom, with at least a part of the bottom surface of the dust separating device being designed as a slanted part of the bottom surface that runs obliquely relative to a transverse plane of the axis of rotation.
  • a first part of the bottom surface of the dust separating device runs in a transverse plane perpendicular to the axis of rotation and a second inclined part of the bottom surface of the dust separating device runs in a plane inclined by a predetermined angle relative to the transverse plane.
  • the second slanted part of the bottom surface runs obliquely outwards towards the front of the vacuum cleaner in the direction of the axis of rotation viewed from the bottom up.
  • a "hand-held vacuum cleaner” is a vacuum cleaner that is designed not only for use with a suction wand or suction hose that connects a suction air inlet of the vacuum cleaner to a floor nozzle for floor cleaning, but also or even designed exclusively for use without such a suction pipe or hose, for example to clean furniture.
  • the group of hand-held vacuum cleaners within the meaning of the present invention also includes vacuum cleaners that, in addition to the aforementioned options, can also be operated with a suction pipe or a suction hose and a floor nozzle that can be connected to the suction pipe or the suction hose for cleaning a floor.
  • the user moves the hand-held vacuum cleaner with the suction tube attached and the floor nozzle attached thereto over the floor area to be cleaned.
  • the motor, fan and dust separation device are in the upper half, particularly preferably in the upper third of the distance from the floor nozzle to a handle of the vacuum cleaner arranged.
  • the hand-held vacuum cleaner because of its compact size and light weight, is adapted to be conveniently held and carried, preferably with only one hand.
  • the weight is particularly preferably less than 2 kg, particularly preferably less than 1.5 kg, in each case without the accumulator. Its preferred length from the handle to the air inlet without a connected suction hose or suction tube is less than 60 cm, more preferably less than 50 cm.
  • Battery operated should be understood to mean that the vacuum cleaner is equipped with an electrical accumulator with which the vacuum cleaner can be operated without an additional power supply. This does not rule out the vacuum cleaner being able to be operated additionally or alternatively via a power supply line, for example when the accumulator is exhausted or while the accumulator is being charged. With the battery operation is advantageously achieved that the freedom of movement of the vacuum cleaner is no longer restricted by a cable for the power supply of the vacuum cleaner.
  • the preferred hand-held cordless vacuum cleaner is a "regular-size cordless vacuum cleaner" according to the February 2017 draft of DIN EN 62885-4.
  • Hand-held battery-operated vacuum cleaners are becoming increasingly popular because they are easy to use and are therefore particularly suitable for vacuuming up small amounts of dirt.
  • hand-held vacuum cleaners have a motor/fan unit for generating the suction air flow, with the suction air being drawn from an intake opening, for example an intake connection, via a dust separator to the motor/fan unit and then, for example, to a blow-out area Outlet openings is performed.
  • the dust separating device is generally designed as a bagless dust separating device in which the incoming air is rotated in order to separate dust and dirt according to the centrifugal separator principle.
  • the dust separator is designed as a bottom-closed dust separator, with the dirt in the bottom area accumulates. At least part of the bottom surface is designed as a part of the bottom surface running obliquely to a transverse plane of the axis of rotation.
  • top, top, bottom, bottom and bottom of the vacuum cleaner are used to describe the hand-held vacuum cleaner.
  • This information relates to a vacuum cleaner placed on a horizontal surface with the base of the vacuum cleaner resting on the surface.
  • the terms “front” and “rear” are defined in relation to the vacuum cleaner such that the suction opening or suction nozzle is located at the front end of the hand-held vacuum cleaner, whereas the suction opening or suction nozzle opposite end of the vacuum cleaner as the rear end or rear area is referred to.
  • a handle for handling the vacuum cleaner can be arranged in the rear area of the vacuum cleaner, for example.
  • the beveled part of the bottom surface is designed to run obliquely with respect to the axis of rotation and with respect to a transverse plane to the axis of rotation.
  • a transverse plane to the axis of rotation is to be understood as meaning a plane perpendicular to the axis of rotation, with a slanted course relative to the transverse plane of the axis of rotation being understood to mean that the bottom surface in the slanted area does not run within the transverse plane to the axis of rotation, but rather runs at an angle to this transverse plane .
  • the formation of at least part of the bottom surface as a sloping bottom surface offers the advantage that the sloping area in the interior of the separating device serves as a run-on surface for the rotating air.
  • the rotating air is slowed down by hitting the slanted surface and the separation of dirt and dust is promoted.
  • the separation takes place in particular at the beginning of the incline, so that a certain accumulation of dust and dirt occurs there. This promotes the clumping of dust and dirt particles and creates fluff and dust bunnies on which further dust and dirt particles can accumulate. These clumps facilitate the separation of further dust and dirt particles.
  • a first part of the bottom surface of the dust separating device runs in one Transverse plane perpendicular to the axis of rotation and a second sloping portion of the bottom surface of the dust separating device runs in a plane inclined at a predetermined angle relative to the transverse plane. Only a partial area of the bottom surface of the dust separating device is formed as a slanted part. The remaining first part of the bottom surface, on the other hand, runs in a plane arranged perpendicular to the axis of rotation.
  • a soft transition or a sharp bend can be provided between the beveled and the non-beveled area of the bottom surface, with dust being able to separate in the interior space precisely at this transition. The separation of dust and dirt is promoted especially in the transition area between the two parts of the floor surface.
  • a further advantage of the at least partially sloping bottom surface is that a wedge-shaped dust collection volume is formed. If coarse dirt, such as larger particles or leaves, is conveyed into this wedge-shaped area by the rotating air, these coarser dirt particles are clamped there and thus removed from the rotating air flow. The wedge shape improves the separation of coarse dirt.
  • a further advantage is that when vacuuming in the working position with the nozzle on the floor, the incline of the floor surface prevents the separated dirt from sliding forward as far as the front wall of the dust separation device. Rather, the separated dirt is held back by the incline and collects at the beginning of the incline. This is advantageous since the dirt thus collects in areas of the dust separating device in which the flow velocities are comparatively low. This means, for example, that less dirt gets into a downstream filter, which reduces maintenance and improves performance. Even when vacuuming overhead, the dirt slips more easily into the area of the dust separation device, in which the flow speed is comparatively low.
  • the slanted part of the floor surface can also be used, for example, as a standing surface or as part of the floor space of the vacuum cleaner, so that the vacuum cleaner, when it is parked on a surface, rests on the slanted part of the floor surface of the dust separating device .
  • the vacuum cleaner housing and the dust separation device arranged in the vacuum cleaner are tilted forward at an angle overall.
  • the tilting of the dust separating device relative to the vertical of the vacuum cleaner leads to a visually smaller appearance of the dust separating device, although the filling volume remains essentially the same despite the bevel.
  • the vacuum cleaner appears smaller and more manageable due to the new design.
  • Another advantage is that the front area of the vacuum cleaner, for example, can be lowered due to the sloping base, while the rear area can be raised.
  • the receptacle for the battery can be arranged, which is raised as a result of the sloping base. This makes access to the battery easier and the battery can be gripped better from the underside.
  • the beveled portion of the bottom surface extends in a plane inclined relative to a transverse plane of the axis of rotation.
  • the beveled portion runs in a plane that is tilted relative to a plane perpendicular to the axis of rotation. Relative to the transverse plane, the sloped part of the floor surface runs at an angle.
  • the beveled part of the bottom surface runs in a plane which is inclined by a predetermined angle relative to a transverse plane of the axis of rotation.
  • the predetermined angle is preferably in the range between 5° and 30°.
  • the predetermined angle is preferably greater than 5°. More preferably, the predetermined angle is above 8°.
  • the predetermined angle is preferably less than 30°.
  • the predetermined angle is preferably less than 20°.
  • the predetermined angle is preferably less than 15°. It is particularly preferred to use a predetermined angle of about 10°.
  • the dust separating device is preferably designed as a centrifugal separator which is designed to separate dust and dirt.
  • the dust separating device is designed in such a way that the inflowing dust-laden air is rotated within the dust separating device. According to the principle of centrifugal force, dust and dirt particles are separated from the rotating air flow and collect at the bottom of the dust separator.
  • the slanted part of the bottom surface forms a standing surface or part of a standing surface of the vacuum cleaner.
  • the vacuum cleaner can stand more stably on a base without the need for further supporting elements or lateral projections.
  • the entire vacuum cleaner when standing on a floor, is tilted forwards at a predetermined angle.
  • the dust separating device which rests with the slanted part of the floor surface on the respective underground when the vacuum cleaner is switched off, is also tilted forward by the predetermined angle, so that the axis of rotation of the dust separating device is also tilted forward.
  • the maximum width of the floor space of the vacuum cleaner essentially corresponds to the outer diameter of the dust separating device. If the slanted part of the bottom surface of the dust collecting device is used as a standing surface or part of the standing surface, the vacuum cleaner can stand stably guaranteed, so that no additional widening of the stand area on the sides is necessary. In this case, the width of the standing area is determined by the outer diameter of the dust separator.
  • the sloped portion of the bottom surface forms the front portion of the bottom surface of the dust separating device.
  • the bottom surface of the dust separating device is designed obliquely in its front area, that is to say in the area directed towards the suction opening or towards the suction nozzle.
  • This arrangement of the beveled part in the front area of the floor surface causes the entire vacuum cleaner housing to tilt forward.
  • the slanted part of the bottom surface runs obliquely outwards towards the front of the vacuum cleaner in the direction of the axis of rotation viewed from the bottom up.
  • the dust separating device has a substantially cylindrical shape, with the axial direction of the cylindrical shape coinciding with the axis of rotation of the rotating air.
  • the inflowing air is coupled with a tangential component into the cylindrical dust separation device and set in rotation about the axial direction of the cylinder, with the air flow being guided through the cylinder jacket.
  • the axis of rotation of the rotating flow corresponds to the axial direction of the cylindrical dust separation device.
  • the dust separating device is designed essentially in the form of a circular cylinder which has a circular base area.
  • the sloping part of the bottom surface preferably serves as a run-on surface for the rotating air. After the air is rotated, the air flow moves in a circular or spiral pattern along the inner wall of the dust collector until it meets the sloping part of the floor surface. The air flow is slowed down and the separation of dust and dirt is promoted. In addition, dust and dirt particles tend to clump together with other dust and dirt particles and form fluff. Such fluff formation, which promotes separation, is promoted by the sloping ramp surface.
  • the front side wall of the dust separating device has a lower height than the rear side wall of the dust separating device because of the inclined part of the bottom surface.
  • the front wall of the dust separating device is shortened by the sloping shape of the bottom surface.
  • an edge is formed in the bottom surface, which runs in the transverse direction of the dust separating device.
  • the vacuum cleaner preferably includes a holder for the dust separating device, with the dust separating device being accommodated in the holder so that it can be removed.
  • the dust separating device can be removed from the vacuum cleaner for emptying the accumulated dust and for cleaning.
  • the dust separating device is preferably arranged in the vacuum cleaner in such a way that the axis of rotation runs inclined at an angle to the vertical of the vacuum cleaner.
  • the vertical of the vacuum cleaner is to be understood in relation to a vacuum cleaner that is parked on a horizontal surface.
  • the axis of rotation of the dust separating device is designed to be inclined relative to the vertical line of the vacuum cleaner defined in this way.
  • the axis of rotation is designed to be inclined forwards in relation to the vertical of the vacuum cleaner in the direction from bottom to top. It is advantageous if the axis of rotation of the dust separating device is arranged inclined at an angle of more than 5° to the vertical of the vacuum cleaner. This inclined arrangement of the dust separating device results in new lines and a slimmer appearance of the dust separating device, although the filling volume remains essentially the same.
  • the oblique inclination of the axis of rotation is preferably predetermined by the incline of the beveled part of the bottom surface. If the beveled part of the bottom surface is designed as a standing surface, for example, then the beveling of the standing surface results in a correspondingly inclined arrangement of the dust separating device and thus also of the axis of rotation.
  • the angle at which the axis of rotation of the dust separating device is inclined relative to the vertical corresponds to the angle at which the sloping part of the bottom surface is sloping. The more the bottom surface is slanted, the further forward the dust separating device is arranged.
  • the dust separating device preferably has an air inlet duct for a dust-laden suction air flow on the intake side.
  • the air inlet duct is preferably arranged in the upper area of the dust separation device. More preferably, the dust separating device has an opening on the upper side, the opening being designed as an air outlet. The cleaned air can flow out of the dust separation device through this opening at the top.
  • the vacuum cleaner preferably includes a rechargeable battery.
  • a rechargeable battery When using a rechargeable battery, the freedom of movement for the user when vacuuming is improved.
  • the rechargeable battery is preferably an exchangeable rechargeable battery, with the vacuum cleaner having a receptacle for the exchangeable rechargeable battery in the rear area.
  • the battery can be used without the use of
  • the previous rechargeable battery is removed, for example, from the receptacle and a new rechargeable battery is inserted into the receptacle.
  • the rechargeable battery can preferably be pushed into the receptacle in a direction that extends obliquely from the rear to the front and below.
  • the previously used battery can be pulled out from the rear side of the device in a direction diagonally backwards and upwards, and the new battery can be inserted in the opposite direction from back to front and downwards.
  • the insertion direction of the receptacle defined in this way makes it easy to remove and insert the accumulator.
  • the receptacle preferably has a guide profile or a guide rail into which or onto which the battery can be slid.
  • the direction in which the rechargeable battery can be pushed into the receptacle preferably encloses an angle in the range of 10° to 30° with a standing plane of the vacuum cleaner.
  • the standing level of the vacuum cleaner is defined by the sloping part of the floor surface designed as a standing surface.
  • the rechargeable battery inserted into the receptacle is preferably arranged at a distance from a standing plane of the vacuum cleaner.
  • An intermediate space is preferably provided between the rechargeable battery inserted into the receptacle and a standing plane of the vacuum cleaner. If the vacuum cleaner is parked on a surface, the battery inserted into the receptacle is therefore arranged at a distance from this surface. For example, the battery can be gripped from its underside and pulled out of the receptacle. The gap between the battery inserted into the receptacle and the ground makes it easier to grip the battery from below.
  • the slanted part of the floor surface preferably forms a standing surface or part of a standing surface for the vacuum cleaner, with a receptacle for a rechargeable battery in the rear area of the vacuum cleaner being raised upwards as a result of the slanted part of the floor surface being designed as a standing surface or part of a standing surface, so that a gap is formed between a battery inserted on or into the receptacle and a standing plane of the vacuum cleaner. If the slanted part of the floor surface is designed as a standing surface or as part of a standing surface for the vacuum cleaner, then the vacuum cleaner rests on this slanted part of the floor surface when it is parked on a subsurface.
  • the entire vacuum cleaner is tilted forward when parked, so that the front section of the vacuum cleaner is lowered and the rear section of the vacuum cleaner is raised. Therefore, the holder for the battery, which is arranged in the rear area of the vacuum cleaner, is also raised due to the sloping standing surface, so that a gap is formed between the battery inserted into the holder and the surface on which the vacuum cleaner is placed .
  • This space makes it easier to grip the accumulator from below.
  • the chamfering of part of the bottom surface therefore raises the position of the battery, making it easier to reach around and replace the battery.
  • the intermediate space is preferably dimensioned in such a way that the rechargeable battery can be gripped and pulled out from its underside.

  • the entire housing of the vacuum cleaner 1 becomes as in figure 3 shown tilted forward.
  • the dust separation device 4 and the axis of rotation 13 are tilted into a forwardly inclined position, so that the axis of rotation 13 is inclined by an angle 33 relative to the vertical 32 .
  • the vertical 32 is fixed in relation to the horizontal base 31 on which the vacuum cleaner 1 rests.
  • the angle 33 between the axis of rotation 13 and the vertical 32 corresponds to the angle 20 by which the beveled part 16 of the bottom surface is inclined relative to the transverse plane 18 .
  • the slanting of the standing surface thus leads to a corresponding forward tilting of the axes of the individual components, so that overall the vacuum cleaner 1 has a new shape.
  • the tilting of the dust separation device 4 makes it appear smaller than it actually is. Due to the slanting of the base, the axis of rotation 34 of the motor/fan unit 5 is also tilted forwards by a certain angle. In relation to the rear area of the vacuum cleaner 1, the sloping base leads to an elevation of the position of the receptacle 10 and the removable battery 9 inserted into the receptacle 10.
  • the removable battery 9 can be removed from the receptacle 10 and into the receptacle without the use of tools 10 are used.
  • the direction in which the battery 9 is inserted into the receptacle 10 is preferably in the range of 10° to 30° relative to the horizontal base 31.
  • the intermediate space 35 located below the battery 9 is enlarged , so that the battery 9 can be gripped and pulled out more easily from its underside. Therefore, by raising the position of the holder 10 upward, the handling of the removable battery 9 is simplified.
