Definitions

  • the invention relates to a portable suction device according to the preamble of claim 1.
  • the invention relates to a portable suction device with a suction channel opening into a suction nozzle and with a housing, a suction material container and a suction unit having at least one electric motor, an accumulator and a fan wheel for generating a suction flow, which provides a negative suction pressure applied to the suction nozzle, and with a separating device, which is able to divide the suction flow sucked in via the suction nozzle into an exhaust air flow flowing out of the suction device and into suction material in the form of particles and/or fluid components, the separated particles or Fluid components are collected in the suction material container.
  • these devices also have a pull-off lip for removing liquids, with the pull-off lip being arranged on the suction nozzle.
  • these devices are usually battery operated and are held in a user's hand while the user guides the squeegee along the surface to be vacuumed.
  • Portable devices of this type are among others from the EP 2 845 530 B1 and EP 0 170 720 A2 known.
  • the known suction devices are used to suck up a liquid/air mixture. As in the case of the device mentioned, this can be done for sucking up liquid, for example from a flat surface such as a table top, window panes or tiles.
  • a squeegee lip arranged on the suction nozzle is provided in the devices of the generic type.
  • EP 3 021 723 A1 describes a portable suction device that provides a separate waterproof unit that includes the electric motor, the accumulator and the component electronics.
  • the separate unit is installed in the housing of the suction device.
  • the encapsulation due to the separate unit within the housing of the electric motor, battery and electronics leads to increased heating of the components, in particular the electric motor, but also the temperature-sensitive battery. This results from the multi-layer structure, which accordingly causes undesirable insulation with poor heat dissipation.
  • the service life of the components can be reduced due to the increased heating.
  • the usage time can also be reduced if the device has to be switched off due to overheating.
  • the object of the invention is therefore to provide a portable suction device which allows the electronic components to be sealed against the ingress of suction material while at the same time providing good heat dissipation and cost-effective production.
  • the portable suction device provides that part of the suction container boundary has a receiving area for receiving electronic components of the suction device, the receiving area being formed in the form of at least one cavity that is watertight except for the opening and is designed to be watertightly closable by a separate intermediate element.
  • the electronic components include at least the electric motor and the accumulator, but can also include other electronic components, such as monitoring and/or control elements arranged on a printed circuit board.
  • the cavity can consist of one or more pockets, with the individual electronic components being arranged in the pockets.
  • the electronic components are protected against the ingress of dust and water by the watertight sealed cavity in the suction container. Furthermore, the arrangement does not have any heat-insulating encapsulation of the components, so that the heat loss occurring during operation of the device can be dissipated easily. This can be done directly via the housing to the environment and also in the vacuumed suction.
  • the intermediate element preferably forms a component carrier, by which at least the electric motor and the accumulator are held.
  • the fan wheel is advantageously arranged and rotatably mounted on the side of the intermediate element facing away from the receiving area.
  • the construction according to the invention is advantageous in terms of production and thus in terms of costs, since the intermediate element is used to form a preassembled assembly that can be used as a whole in one assembly step.
  • the intermediate element can preferably be designed geometrically in the form of component receiving elements in such a way that at least the electric motor and/or the accumulator can be received in a defined manner.
  • Individual pockets or receptacles or also ribs can be provided in the intermediate element.
  • the electronic components are inserted and held in these. It is advantageous if, for example, the electric motor and the accumulator as well as any printed circuit board with measuring and control elements are arranged in separate pockets.
  • the walls of the pockets at least partially insulate the electronic components from one another, so that the waste heat from the electric motor does not additionally heat up the accumulator or the circuit board.
  • the pockets are preferably designed in such a way that, on the one hand, good heat dissipation of the components and thermal insulation between the electronic components is achieved. On the other hand, in such a way that the electronic components are held securely in the pockets. This can be realized, for example, by pockets with walls of different heights and/or recesses within the pockets.
  • soft elements can be arranged on the intermediate element and/or in the receiving area, with the electronic components, in particular the electric motor and/or the accumulator, softly mounted, are arranged in the intermediate element. This is advantageous when the intermediate element is constructed with a plurality of pockets in which the individual electronic components are accommodated.
  • the soft elements are arranged and designed in such a way that the electronic components are held by the intermediate element without play.
  • the soft tissue support also acts advantageously as a damper for the electronic components if the device is put down roughly or accidentally falls down.
  • means are provided which are set up to improve the heat dissipation of the electronic components.
  • the means can be formed by heat-conducting areas in the area of the intermediate element and/or in the area of the receiving area.
  • the heat-conducting areas can be structurally formed by ribs or similar designs and/or can be achieved by a heat-conducting material combination.
  • the thermally conductive areas can be formed by overmolded metal.
  • the intermediate element and the component receiving elements of the intermediate element that accommodate the electronic components are preferably made of plastic.
  • thermally conductive particles for example copper particles, can be added to the plastic.
  • the geometry of the suction device is designed in such a way that the heat dissipation in the direction of the suction material container or suction material is higher than in the other directions.

  • the intermediate element advantageously has a circumferential sealing contour as a sealing element.
  • the cavity formed by the suction material container limitation The receiving area can have a one-sided and planar opening.
  • the circumferential sealing contour of the intermediate element can be flat.

  • the seal of the intermediate element can also be injection molded.
  • the fan wheel is arranged on the side of the intermediate element facing away from the receiving area and is driven by the electric motor.
  • the intermediate element has a passage opening for the motor shaft.
  • a motor shaft seal is provided to seal the motor shaft.
