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 for generating a suction flow that provides a suction negative pressure at the suction nozzle, and with a separation device that can 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, wherein the separated particles or fluid components are collected in the suction material container.
  • these devices also have a squeegee lip for removing liquids, wherein the squeegee lip is arranged on the suction nozzle.
  • these devices are usually battery-operated and are held in the hand of a user while the user guides the squeegee lip along the surface to be vacuumed.
  • Portable devices of this type are available from CN 103 445 718 A or the EP 2 845 530 B1 known.
  • the known suction devices are used to suck up a liquid/air mixture. This can be done, as in the case of the device mentioned, to suck up liquid, for example from a flat surface such as a table top, window panes or tiles.
  • the generic devices In order to clean the surfaces without leaving any residue, the generic devices usually have a squeegee lip arranged on the suction nozzle.
  • the suction material is stored in a suction material container and must therefore be separated from the suction flow and the air flow.
  • the known separation devices of portable suction devices use baffle plates and air deflectors to separate the suction material from the suction flow. Due to its inertia, the suction material cannot follow the narrow air deflectors and runs into the area of the Suction material container, where there is usually no air flow.
  • the devices often also have a suction pipe that is fluidically connected to the suction unit and extends from the side of the suction unit into the suction material container. In order to prevent the suction material from escaping from the suction material container via the suction pipe, the devices also have intermediate storage areas that are formed around the suction pipe that extends into the suction material container.
  • the document EN 10 2013 021 277 A1 a portable suction device in which the suction channel and the inlet of the suction material container are connected to each other without detours.
  • a baffle plate is provided against which the suction flow bounces and allows a large part of the suction material to bounce off into the suction material container.
  • the air deflectors mentioned above are used.
  • Vacuum cleaners designed in this way have disadvantages. Sharp air deflections and impact plates cause pressure losses that negatively affect the efficiency of the vacuum cleaner. For the user, this means a shorter device running time for a given usable battery capacity.
  • the separation via a baffle wall promotes the formation of foam in liquids, which can lead to a layer of foam building up in the separation area and preventing the separated liquid or the suction material from draining away. Such a build-up in turn leads to liquid entering the suction pipe and thus being released from the device as splashes and drops from the air outlets.
  • the known devices with suction pipe and intermediate storage areas also require a certain amount of space around the suction pipe. This is to prevent separated water or suction material from entering the suction flow when the suction device is swiveled and thus manifesting itself in the form of splash water from the ventilation outlets of the device. This can be reduced or avoided by making the separation area and/or the intermediate storage areas larger, but this leads to an overall unwantedly larger suction device.
  • the document also describes FR3 019 997 one-piece rotors that have a rotary separator with a wing contour that extends into the suction flow on the suction side. While the air can flow through the separator wings without major impairment, the more sluggish suction material, in particular the more sluggish water droplets, are knocked out of the air flow and separated. However, this has the disadvantage of causing the droplets to atomize, so that a residual amount of the atomized liquid is carried along by the air flow and transported out of the device via the rotor. This then becomes noticeable to the user in an unwanted way as spray mist.
  • the document CN 103 445 718 A describes a generic suction device in which the separation device is designed as a rotary separator.
  • the object of the invention is to provide a portable suction device which, with a compact design and at the same time efficient operation, enables a high separation of the sucked-in suction material.
  • the separation device is designed in at least two stages, comprising a suction material guide element and a rotary separator, wherein the suction material guide element is arranged in the flow direction as a continuation of the suction channel and is set up to partially separate suction material.
  • the rotary separator is arranged in the flow direction behind the suction channel and aligned in the direction of the suction channel and is set up to separate the suction material not separated by the suction material guide element.
  • the suction material guide element forms a first stage of separation and the rotary separator forms a second stage of separation.
  • the solution according to the invention makes it possible to realize a smaller design of the suction device, since in particular the air deflections required in the solutions from the prior art are not required and the necessary safety distances in the area of the separation device can be reduced.
  • the two-stage separation and in particular the omission of impact plates or air deflectors prevent the formation of foam and the associated escape of suction material from the device.
  • the separating device has a cover element with an opening and the rotary separator extends through this opening in the direction of the suction nozzle.
  • the cross-sectional area of the rotary separator can preferably be tapered in the direction of the suction nozzle in a way that is adapted to the flow.
  • the cover element can preferably also be part of the suction unit housing.
  • the cover element preferably has an inlet nozzle around the opening facing the suction nozzle.
  • the nozzle can advantageously be designed in such a way that suction material hitting it is guided away from the opening, which is preferably designed as an exhaust air opening.
  • the inlet nozzle can be shaped so as to taper conically towards the suction nozzle.
  • This design of the cover element is advantageous in terms of flow. It also ensures that the suction material is diverted away from the suction unit and thus away from the air outlet.
  • the rotary separator can preferably be part of the suction unit, wherein the suction unit in particular has a fan wheel and the rotary separator is formed in one piece with the fan wheel.
  • the separating chamber provided in the suction device according to the invention is arranged between the suction channel and the suction material container, with the separating chamber being delimited by the housing of the suction device and the cover element.
  • the separating chamber at least one inlet opening for the suction flow through the suction channel and an exhaust air opening for the exhaust air flow and an outlet opening for the suction material are provided in the part of the suction unit housing.
  • the exhaust air opening is preferably the opening in the cover element through which the rotary separator protrudes.
  • the first stage of separation takes place via the suction material guide element.
  • This is advantageously aligned directly in the direction of the suction material container.
  • the inlet to the suction material container or an upstream suction material guide which in turn leads to the suction material container, is arranged below the suction channel for good suction material separation when used as intended.
  • the inlet to the suction material container or to the upstream suction material guide forms the discharge opening of the separation chamber.
  • the suction material guide element has a ramp-like shape.
  • the suction material guide element is designed in such a way that the suction material is guided in a direction that differs from the suction material flow.
  • the more inert suction material is guided along the suction material guide element by its higher mass inertia and by gravity, whereas the air is sucked out of the suction flow by the suction unit.
  • the adhesion of the liquid suction material to the suction material guide element is also supported by the effective surface forces.
  • the suction material container is connected to the discharge opening of the separation chamber indirectly via a suction material guide or directly via an inlet opening.
  • the cover element with the additional opening seals the inlet opening of the suction material container against the environment.
  • the inlet opening is advantageously formed indirectly via an inlet of a suction material guide.
  • suction material guide element has a hydrophilic material so that liquid suction material in particular adheres better to the suction material guide element and does not detach itself unintentionally and preferably follows a change in direction through the suction material guide element.
  • the suction material guide element can also be designed in such a way that the suction material is guided in a direction that deviates from the suction material flow.
  • the suction material guide element can be designed in such a way that unwanted detachment of the suction material is prevented and/or the drainage of the suction material is improved.
  • the suction material guide element For example, it can have ribs and/or raised and/or recessed surface structures.
  • one or more detachment sections can be provided in the area of the suction channel and/or the suction material guide element, which are designed to detach the suction material from the surface of the suction channel and/or the surface of the suction material guide element in a controlled manner and to guide it away from the suction unit and the rotary separator. This can be done, for example, by means of notches and/or bulges and/or guide vanes or guide ribs.
  • Such flow guide elements can also be designed in such a way that the suction flow is given a swirl by the flow guide elements.
  • the suction material guide element further preferably has an opening in the area of the discharge opening from the separation area or the separation chamber, which opening is designed to prevent suction material from collecting in an area covered by the suction material guide element and/or to prevent the suction material from flowing back from the separation area or the separation chamber via the suction material guide element when pivoting, in particular by 180°.
  • the opening is particularly preferably U-shaped.
  • the suction material guide element can preferably be designed as a separate part.
  • the suction material guide element has a detachable clamping and/or snap connection that interacts with the suction channel.
  • the suction material guide element can also be designed as part of the housing of the suction device.
  • a reach-in guard can be provided in the area of the suction channel.
  • the reach-in guard can preferably also be designed as part of the suction material guide element.
  • a filter element can be provided in the area of the suction channel.
  • the filter element can in particular be detachably connected to the suction channel and/or the suction material guide element and/or be formed by the suction material guide element and/or be designed as a protection against intrusion.
