Definitions

  • the invention relates to a device for cleaning floors, in particular a vacuum cleaner.
  • vacuum cleaners which, in addition to the dust filter bag required to collect the dust, are equipped with a microfilter.
  • the microfilter is used to retain the finest dust particles from the exhaust air stream. It is arranged in the flow path between a first blow-out cross section of a blower housing accommodated in the housing and the inlet cross-section of a microfilter screen provided with blow-out slots.
  • the microfilter screen can be opened to change the microfilter.
  • the inlet cross section of the microfilter screen must be chosen to be relatively small due to the design, which requires a high exhaust air throughput.
  • the microfilter upstream of this inlet cross-section essentially corresponds to the size of the inlet cross-section. Due to the relatively high exhaust air flow rate, the microfilter clogs up quickly and must therefore be changed frequently. If the change takes place not in time, the exhaust air throughput and thus the suction power of the vacuum cleaner decrease.
  • the object of the invention is to provide a device with which the disadvantages of the prior art are avoided.
  • a compact vacuum cleaner is to be provided, the microfilter of which has to be changed less frequently.
  • a device for floor cleaning in particular a vacuum cleaner, is provided with a fan housing accommodated in a housing and having a first blow-out cross section and an exhaust air guide element, the exhaust air guide element having a first intake cross section corresponding to the first blow-out cross section and a second blow-out cross section which is smaller than that first inlet cross section is.
  • the size of the microfilter is no longer determined by the inlet cross-section of a microfilter screen.
  • the microfilter can be as large as the first blow-out cross section of the blower housing. This prevents the filter from clogging quickly and increases its service life.
  • the second discharge cross section is expediently smaller by at least 30% than the first inlet cross section. - This enables particularly compact housing dimensions.
  • the exhaust air guiding element can be pivotally connected to the blower housing and can be locked with it or with the housing, which enables a particularly simple change of the microfilter.
  • the exhaust air guide element has a box with grid-like air guide walls and air guide floors, a transverse wall closing the first inlet cross section in sections being provided on the side of the box having the second outlet cross section.
  • the transverse wall serves to reduce the first inlet cross-section to the second outlet cross-section.
  • the air guide plates are advantageously arranged between the first inlet cross section and the second blow-out cross section.
  • a handle element and an outlet cover which can be locked with the exhaust air guide element can be provided on the exhaust air guide element.
  • the outlet panel expediently has a second inlet cross section corresponding to the second outlet cross section, so that a tight connection can be established between the outlet panel and the exhaust air guiding element.
  • the outlet orifice has a third outlet cross-section, which is preferably formed from a plurality of slots. - The gradual reduction of the blow-out cross-sections from the blower housing to the slots contributes to sound insulation of the device.
  • the outlet panel can have two side walls, each with an opening for engagement in corresponding latching projections provided on the box. This enables a particularly simple assembly of the outlet panel on the exhaust air guiding element.
  • one of the side walls can have an exhaust air bypass opening.
  • a filter preferably a microfilter, is held between the first discharge cross section and the first inlet cross section. It is conceivable to provide a further microfilter between the second and the third blow-out cross section.
  • the exhaust air guiding element is preferably made of a heat-resistant plastic.
  • Fig. 1 shows a side view of a vacuum cleaner with a housing 1, which has a dust chamber cover 2, an outlet cover 3, a connector shaft 4 and a lower housing half-shell 5.
  • Fig. 2 shows a perspective view of an exhaust air guiding element 6 and the outlet panel 3.
  • the exhaust air guiding element 6, which is made of high-temperature-resistant plastic, consists essentially of a box 7 with a circumferential first frame 8 and a transverse wall 9. Inside the box there are air guiding walls 10 and Air guide floors 11.
  • a first inlet cross section E1 facing away from the image plane is delimited by the first frame 8.
  • a second blow-out cross section A2 is reduced by the size of the transverse wall 9 compared to the first inlet cross section E1.
  • the second discharge cross-section A2 is approximately 60% of the first inlet cross-section E1.
  • hinge pin supports 12 with hinge pins 13 and a handle element 14 are injection molded at the upper end.
  • a locking projection 15 on the outside of the frame.
  • the outlet screen 3 consists essentially of a curved outer wall 16, in which a plurality of slots 17 are provided, the total area of which defines a third blow-out cross section A3.
  • a second inlet cross-section E2 (not shown here) essentially corresponds in shape and size to the second blow-out cross-section A2.
  • a first side wall 18a on the outlet panel 3 has a first latching opening 19a which corresponds to the latching projection 15.
  • FIG. 3a to 3c again show the outlet panel 3 in detail.
  • a recess 20 is provided, in which the grip element 14 is received in the locked state.
  • a second side wall 18b has a second latching opening 19b and an exhaust air bypass opening 21. Filtered air can be directed to the electronics for cooling by means of the exhaust air bypass opening 21.
  • FIG. 4 shows a perspective view of a blower housing 22 with an integrally formed plug shaft 4.
  • Receptacles 24 for the hinge pins 13 are provided below the second frame 23.
  • the function of the device is as follows:
  • Exhaust air sucked in by a fan (not shown here) is expelled through the first blow-out cross section A1.
  • the hinge pin 13 is held in the receptacles 24 so that it can pivot Exhaust air guide element 6 on the second frame 23, a microfilter element (not shown here) being clamped between the air guide webs 25 and the air guide walls 10 and the air guide floors 11.
  • the filtered exhaust air is passed through the second outlet cross section A2 with the assistance of the air guide walls 10 and the air guide floors 11 and reaches the outlet orifice 3. A substantial part of the filtered exhaust air is blown out into the environment through the slots 17. A small part of the filtered exhaust air is branched off through the exhaust air bypass opening 21 and serves to cool the device electronics.
  • the exhaust air guiding element 6 which is locked in place on the housing 1 or on the blower housing 22, can be released from its locked position with the aid of the grip element 14 and folded away from the housing 1. In the folded-away state, the microfilter element can be replaced and then the exhaust air guiding element 6 can be returned to the locked position.
  • the technical teaching given here can be used particularly advantageously on devices with a microfilter, but is in principle also suitable for devices without a microfilter, since an essential element of the technical teaching is the reduction in the size of the blow-out opening with sufficient efficiency in relation to the air resistance.
