Definitions

  • Embodiments relate to a collecting container for collecting particles for a vortex separator and a lid for closing a discharge opening of a collecting container of a vortex separator. They can be used, for example, in the context of a vacuum cleaner based on the centrifugal principle.
  • a degree of separation of the vortex separator can be increased.
  • One measure for increasing the degree of separation of such a vortex separator is to increase an ejection opening, through which the particles separated by the vortex separator are separated.
  • This can lead to stronger air movements inside its container. This may mean that, for example, long hair but also other dirt particles from the container (collection container, box) pass through the ejection opening in the reverse direction. So for example, particles which have already been separated can again enter the separation space of the vortex separator, in which the vortex is formed.
  • a downstream filter for example a fine dust filter, can be clogged in the case of a corresponding vacuum cleaner.
  • the US 2003/0051452 A1 and the US 2006/0042039 A1 refer to working on the cyclone vacuum cleaner in which in appropriate dust collection containers, ie the collection containers, the necessary for the operation vortex is formed. To slow down the air and to forward the at least pre-cleaned by the centrifugal force air along the center of the vortex formed in the dust container, these have finger-like structures or projecting parts at the bottom of the corresponding dust container, which brake the air flow.
  • the EP 1 547 509 A2 refers to a dirt trap for a cyclone vacuum cleaner, in which a guide rib is attached to an opening which connects the dirt collecting chamber with the Abscheidehunt in which the vortex forms.
  • the DE 20 2011 003 563 U1 describes a vacuum cleaner with cyclone separation of the waste.
  • the vacuum cleaner comprises a waste separation assembly having a first cyclone separation stage with a primary cyclone separation or inertia separator and a second cyclone separation stage with a plurality of cyclone separators.
  • the wastes separated by the two cyclone separation stages are collected in a container having at least a first and at least a second compartment associated with the first and second separation stages, respectively, the lid having anti-accumulation means adjacent the first inlet opening to prevent the rise of waste in the separation chamber of the first separation stage.
  • An embodiment of a collecting container for collecting particles for a vortex separator comprises a housing element which separates a collecting volume of the collecting container from a separating space of the vortex separator. It further comprises an opening in the housing element, which is arranged such that particles can pass through the opening from the separation space into the separation volume of the collection container due to a vortex prevailing in the separation space of the vortex separator.
  • a collecting container comprises a plurality of retaining elements, which extend at least partially into the collecting volume, wherein the retaining elements each have a recess on a side facing away from the opening.
  • a lid for closing an emptying opening of a collecting container of a vortex separator comprises an opening which is formed and arranged such that particles due to a in the Abscheideraum prevailing vortex can pass through the opening of the separation chamber in a collecting volume of the collecting container.
  • a lid further comprises a plurality of retaining elements which are connected to the lid. The retaining elements protrude in the direction of the collecting volume beyond an edge of the opening, wherein the retaining elements each have a recess on a side facing away from the opening.
  • a collecting container according to an embodiment and a lid according to an embodiment in this case is based on the finding that by providing the plurality of retaining elements long hair and other corresponding fibrous particles can be better retained even in the case of a large opening between the collecting container and the separation, without to massively reduce the inflow or entry of particles and longer hairs into the collecting container due to a reduction in the cross section of the opening and / or to make filling of the collecting container with the particles or long hairs very uneven. For example, this can be achieved in a robust manner by comparatively technically simple means with little additional cost.
  • a collecting container or a lid according to an exemplary embodiment thus comprises a plurality of retaining elements, that is to say at least two retaining elements.
  • a receptacle or a lid according to an embodiment may also comprise more than two corresponding retaining elements, for example three or more.
  • a corresponding housing element may, for example, be a removable cover, a ceiling, a side wall or optionally also a bottom surface of the collecting container or its housing.
  • a lid for a collecting container represents a special embodiment of a housing element.
  • the collecting volume in this case represents an interior of the collecting container.
  • the collecting container serves to receive and retain the particles deposited by the vortex separator and conveyed through the opening into the collecting container until it is typically emptied by a user.
  • the housing element or the cover is often designed as a substantially planar component, in which optionally stiffening or improving the mechanical stability stiffening structures, such as stiffening ribs, may be formed.
  • the collecting container and its components that is, for example, the housing element but also the plurality of retaining elements, can be produced from the same material, for example a plastic, in the context of an injection molding process or another corresponding production process.
  • the retaining elements may be connected to the housing element.
  • the retaining elements may thus be integrally connected to the component of the collecting container, which forms the opening for connecting the collecting container and the separating chamber.
  • the retaining elements with the housing element directly, so for example by a direct molding, for example, during a common manufacturing process, connected.
  • the term "connected” is therefore to be understood in the sense of an immediate connection, structures for mechanical stabilization and other production-related structures are not taken into account. This may make it possible, if appropriate, to place the retaining elements better in relation to the undesirable air swirls that may form inside the collecting container, however.
  • the retention effect can be improved.
  • the retaining elements may extend beyond an edge of the opening of the collecting container into the collecting volume. This may make it possible, if necessary, to further improve the retention effect of the retaining elements, since their retention effect tends to increase with retaining elements becoming longer, ie the further they extend beyond the edge of the opening into the collecting volume. In other words, the retaining elements can project beyond a plane in the direction of the interior of the collecting container, the plane being defined by the edge of the opening towards the interior of the collecting container.
  • the opening may in this case, for example, asymmetric, for example laterally offset executed.
  • it may be substantially rectangular or square, but also round. If it has a rectangular or square shape, for example, the corners can be rounded.
  • the opening in the housing element or in the cover can often be increased, as previously explained.
  • the opening may have a size along a direction that corresponds to at least 50%, optionally at least 60%, at least 75%, or possibly even at least 80% of a length of the housing member or lid along the corresponding direction.
  • the opening may comprise an edge portion which surrounds at least 25% of a circumference of the opening, wherein the edge portion projects into the collecting volume and an end of the edge portion facing the collecting volume forms the edge of the opening.
  • the corresponding edge portion may also include, for example, at least 40%, at least 60% or, for example, at least 80%. Of course, the edge portion of the opening completely, ie 100% surrounded.
  • the retaining elements may protrude at least 5 mm, but at most 50 mm in the direction of the collecting volume over the edge of the opening. Basically, it holds that the further the retention elements protrude beyond the edge of the opening, their retention effect improves. If the retention elements protrude, for example, at least 5 mm, optionally at least 10 mm beyond the edge of the opening, the retention effect can be improved in many cases in comparison with smaller retention elements.
  • a distance from the opening to a bottom area (height) at which collect the dust or the particles and the hair is in the range of less than 20 cm, a length the retaining elements beyond the edge of the opening to limit upward to achieve the most uniform possible filling of the collecting container. If the length of the retaining elements is too large, it may happen that the catch containers are too shallow, so that they are no longer filled evenly. This could have the consequence that the collecting container can absorb a significantly smaller amount of particles or dirt than would correspond to its collecting volume.
  • the retaining elements may be advisable to extend the retaining elements also at most to 40 mm, not more than 30 mm or at most 20 mm beyond the edge of the opening.
  • the retaining elements may at least partially extend into a projection of the opening which is substantially perpendicular to the opening.
  • a projection can, for example, take place substantially perpendicular to the opening in a plane in the direction of the collecting volume.
  • the retaining elements may have a surface section which runs obliquely relative to the edge of the opening and / or has a rounded surface section, wherein the surface section projects at least partially into a projection of the opening, which is substantially perpendicular to the opening, and faces the opening ,
  • a resistance to particles entering through the opening can be reduced even in the case of retaining elements projecting into the projection of the opening. These can slide off the surfaces.
  • the corresponding surface sections can thus project, for example, into the cross section of the opening.
  • they may optionally be attached to the top and / or bottom of the retaining elements.
  • the retaining elements, or elements for short, can thus taper in the direction of the dust ejection.
  • the retaining elements may be arranged completely outside a projection of the opening which is substantially perpendicular to the opening. In this way, it may be possible to prevent backflow of particles, for example long hairs and other dirt particles, from the collecting container through the opening into the separating space of the vortex separator by the retaining elements, but without reducing a cross section of the opening. As a result, if appropriate, a degree of separation of the vortex separator can be further increased.
  • the retaining elements may have a web-shaped or rib-shaped section connected to the housing element, wherein the section may be formed in a straight and / or arcuate manner.
  • the sections may in this case have an end face and a side face, wherein the end face is narrower than the side face and wherein the retaining elements are arranged such that the end face of the opening is substantially facing.
  • At least one retaining element of the plurality of retaining elements may have a section connected to the housing element and one with the section at an angle between 20 ° and 70 °, for example below have an angle of substantially 90 ° connected further section.
  • the retaining elements can be arrow-shaped, cross-shaped or also designed as a St. Andrew's cross-shaped, with the further section standing in many embodiments in the projection of the opening or the opening itself.
  • the retention function of the retaining elements can optionally be further increased.
  • the further section may have a previously described surface section, which allows a sliding of incoming particles and hair.
  • the retaining elements may have a section which has a cross-section which partially or completely has the shape of a regular polygon, for example a triangle or a square, and / or an ellipse and / or a circle.
  • the retaining elements can be designed, for example, in a columnar or dome-like manner. These may, for example, be connected to the housing element, that is to say, for example, with a cover of the collecting container, but may, if appropriate, also be arranged at other locations of the collecting container.
  • These retention elements can thus enable rewinding, especially with long-fiber particles, for example hair, which can be advantageous for the retention function. With these retaining elements, it may be advantageous to provide a higher number, for example at least three, four, six, ten or sixteen.
  • the recess may extend partially or completely across a width of the retaining elements substantially perpendicular to an alignment direction of the respective retaining element, the alignment direction extending from a position of the respective retaining element to the opening.
  • an additional recess can be created, on which a particle, for example a hair, can be retained.
  • Corresponding recesses may for example be arranged on a rear side and / or also on an underside of the respective retaining element, to name only two examples.
  • the recesses may further be formed such that they have an undercut, so that forms a barb.
  • the retention effect of the retaining elements can be further improved.
  • the retaining elements may have a transition section which is arranged between an end face and a bottom face of the retaining elements.
  • the transition sections can hereby be rounded and / or obliquely executed. In this way, even with a provision of a corresponding retaining element, an optionally improved entry of particles can be achieved in that they can slide along the transition sections and thus reach the collecting container without being stopped by the retaining elements.
  • the retention members may extend at least along or parallel to a portion of a perimeter of the opening, wherein the portion comprises, for example, at least 25% of the circumference of the opening, or wherein the retention members are entirely along or parallel to the edge of the opening can be arranged.
  • the partial section also runs parallel to the circumference or the edge of the opening. This may make it possible to reduce the number of retaining elements, if necessary, and to arrange them there, and to prevent them immediately in the region of the opening at a return into the separation space of the vortex separator.

  • the retaining elements can be arranged, for example, around the opening, but for example only on one or more sides of the opening. Likewise, they can also be arranged at other locations on the housing element and / or the collecting container.
