  • the invention relates to a Saug lenderssvoroplasty with the features of the preamble of claim 1.
  • Vacuum cleaning devices with a suction head which has a suction unit, and a dirt collecting container, which can be acted upon by the suction unit with negative pressure to form a suction flow, suction air sucked together with suction through a suction inlet into the dirt collecting and suction sucked air from the suction unit via one on the suction head
  • Suction outlet can be discharged to the environment, are known for example in the form of so-called industrial vacuum cleaner, which are used in particular for the extraction of dusts on machinery and equipment. They have a dirt collecting container, which can be acted upon by a suction unit with negative pressure.
  • a suction flow can be generated, under the action of which suction material, that is to say, in particular dusts, can be sucked into the dirt collecting container.
  • suction material that is to say, in particular dusts
  • a filter device is usually arranged in the region of the flow connection between the dirt collecting container and the suction unit.
  • the operation of the suction unit is in particular when, with the aid of the suction unit, a suction flow can be achieved with a high volume flow, associated with a not inconsiderable noise.
  • the noise is often amplified by the fact that often forms a pulsating suction flow.
  • a Saugmaniasvortechnisch with the features of the preamble of claim 1 is from the document WO 97/13443 A1 known. It describes a vacuum cleaner whose suction unit in a suction head is arranged and applied to a dirt collector with negative pressure. Suction air can be sucked together with suction material via a suction inlet into the dirt collecting and the sucked suction air can be discharged via a arranged at the suction suction to the environment.
  • a flow channels exhibiting sound insulation material is arranged and an electric motor of the suction unit is surrounded by flow channels having Schalldämmmaterial. The suction air can pass from the suction unit to the suction outlet via the flow channels of the sound insulation materials.
  • Object of the present invention is to develop a Saugquelsvorraum of the type mentioned in such a way that their noise can be kept low and the Saugquelsvortechnik has a compact design and easy installation, maintenance and servicing.
  • the suction unit is covered by a hood having the suction outlet.
  • the suction air sucked in by the suction unit can be released to the environment via the suction outlet.
  • an outlet channel is arranged in the hood, which receives a silencer.
  • the arranged within the hood exhaust passage with the muffler has a considerable noise reduction result.
  • the arrangement of the outlet channel within the hood causes a higher mechanical stability of the entire suction head, since the outlet channel arranged upstream of the suction outlet is protected from mechanical damage by the hood.
  • the suction outlet may be disposed on an upper side of the suction head. This is particularly advantageous when the suction unit has an axial fan, which sucks the suction air in the axial direction, that is parallel to the axis of rotation of the fan of the suction unit and emits the sucked suction air in the axial direction.
  • the axis of rotation of the axial fan can be vertically aligned, so that the suction air from the axial fan can be sucked from below in the vertical direction and then discharged vertically upward through the suction outlet. Between the suction outlet and the axial fan, the outlet channel can be positioned vertically aligned. The number of flow deflections, which experiences the suction air within the suction head, can be kept low. This in turn results in additional noise reduction.
  • Control electronics of the vacuum cleaning device are arranged in a housing formed by the hood of the suction head.
  • This allows a compact design of Saugquelsvortechnische, wherein the hood in addition to its noise-reducing function also has the function to provide a receiving space for the control electronics.
  • the receptacle is designed as a recess formed in the hood, which is covered by a cover.
  • the lid which is detachably connected to the hood, allows easy access to the control electronics. This not only allows easy installation of Saugquelsvorplatz but also facilitates their maintenance and servicing.
  • the recess of the receptacle formed by the hood has side walls which are arranged at a distance from an outer wall of the hood.
  • the outlet channel is integrated in the hood. It can be provided, for example, that the outlet channel in combination with the hood forms a one-piece plastic molded part. As a result, the manufacturing cost can be kept low and the one-piece plastic molded part can have a considerable mechanical stability.
  • the outlet channel comprises a channel wall which is surrounded by an outer wall of the hood.
  • the outer wall of the hood does not form part of the channel wall of the outlet channel, but the channel wall is arranged at a distance from the outer wall. As a result, the noise can be reduced.
  • the silencer arranged in the outlet channel has at least one air-permeable sound-damping element which extends over the entire horizontal cross-section of the outlet channel.
  • the at least one sound-absorbing element forms a positive connection with the outlet channel.
  • the at least one sound-damping element can be inserted into the outlet channel without tools. This facilitates the assembly of the Saugtherapiesvorraum.
  • the at least one sound-absorbing element is made of a foam in an advantageous embodiment of the invention.
  • a foamed plastic material is used as foam.
  • a flame retardant plastic material is advantageous.
  • the at least one sound-damping element preferably has a plurality of through-channels.
  • the individual through channels are arranged at a distance from each other. Preferably, they have a straight course. It can be provided, for example, that the through-channels in each case parallel to Rotary axis of the suction unit are aligned. In particular, a vertical orientation is preferred.
  • a single sound-absorbing element is arranged in the outlet channel. It is more favorable, however, if several sound-absorbing elements are arranged one above the other in the outlet channel. The size of the individual sound insulation elements can be kept low. This facilitates their handling during assembly of the Saugtherapiesvorraum.
  • the individual sound-absorbing elements can each have a plurality of through-channels, with at least some through-channels of noise-damping elements abutting directly against one another only partially overlapping. When using several sound insulation elements, these can be stacked in the outlet channel. If the soundproofing elements each have a plurality of passage channels, then it is favorable if at least some of the throughflow channels of acoustically damping elements which adjoin one another directly only partially overlap. This reinforces the sound insulation producible by means of the sound insulation elements.
  • a plurality of identically designed sound insulation elements are arranged one above the other, each having a plurality of passage channels and are rotated relative to a longitudinal axis of the outlet channel relative to each other.
  • two directly abutting sound insulation elements on a different angular position with respect to the longitudinal axis of the outlet channel This has the consequence that arranged radially offset from the longitudinal axis of the outlet passage passages of the soundproofing elements overlap each other only partially.
  • the soundproofing elements can preferably be inserted into the outlet channel without tools. When inserting then only has to be taken to ensure that the sound-absorbing elements have a different angular position relative to the longitudinal axis of the outlet channel. The installation of the soundproofing is thus very simple and yet can be achieved by means of the outlet channel superimposed soundproofing elements a strong noise reduction.
  • the muffler fills the volume of the outlet channel in an advantageous embodiment of the invention to at least 75%.
  • a filling of the outlet channel to more than 85%, preferably to more than 90% is to achieve a high noise reduction advantage.
  • the suction unit of the vacuum cleaning device has an electric motor, in particular a three-phase motor, which drives a suction fan of the suction unit.
  • an axial fan is preferably used.
  • the electric motor is surrounded by an annular wall to form an annular space.

  • the annular wall in combination with the hood forms a one-piece plastic molded part.
  • the outlet channel is preferably arranged laterally next to the annular wall surrounding the electric motor, wherein a channel wall of the outlet channel is rigidly connected to the annular wall.
  • a rigid connection between the channel wall and the annular wall has been found to increase the mechanical stability of the one-piece plastic molding as favorable.
  • the vacuum cleaning device has control electronics.
  • the control electronics also serves to electrically control a filter cleaning device, with which a filter material arranged in the flow area between the dirt collecting container and the suction unit can be cleaned.
  • a filter cleaning device with which a filter material arranged in the flow area between the dirt collecting container and the suction unit can be cleaned.
  • a suction is arranged, in which opens at least one closable by a closing valve forced air inlet, wherein by opening the closing valve, the clean side of the filter device can be acted upon with external air.
  • At least part of the inflowing external air can flow through the filter device in the counterflow direction, ie counter to the direction of the suction flow which occurs during normal suction operation. This assists in the removal of solids from the side of the filter device facing the dirt collector.
  • the at least one closing valve is in this case only briefly opened, so that the inflowing external air impinges the filter device jerky.
