  • the air outlet openings open in the known versions in areas with a high negative pressure, for example, in a suction connection associated tilting joint or a suction channel within the housing.
  • a corresponding embodiment is also from the JP 9 047 395 known.
  • the suction-effective air volume and the pressure prevailing at the suction mouth vacuum is reduced by the required for cooling secondary air flow, the non-contributing to the suction side air flow is also referred to as incorrect or false air. Due to the required minimum amount of cooling air a good seal in the known versions of a Elektrorosaugkopfes is not possible.
  • the invention has the object, in an electric vacuum head with the features described above to improve the suction and energy efficiency.
  • the absorbent air amount can be maximized.
  • the object is achieved in that the at least one air outlet opening is arranged on the underside of the housing such that the exiting during operation of the electric vacuum head from the air outlet opening cooling air passes through at least one of Saugmundkanten in the suction ,
  • the air inlet openings of the engine compartment when sucking there is usually about the ambient pressure wherein in the region of the underside of the housing in which the air outlet opens, at least a slight negative pressure is created, whereby air is sucked from the environment and directed to the cooling of the engine and after leaving the air outlet openings together with a sucked at the bottom of the housing main air flow enters the suction mouth.
  • the required cooling air is passed over at least one of the suction mouth edges and thus contributes to the total amount of air that is effective for suction.
  • For the partial air flow of the cooling air takes place only in the flow direction before the Saugmundkanten a displacement of the suction.
  • At the at least one air outlet opening at the bottom of the housing prevails in comparison to the known embodiments in which the air outlet opening is connected to a tilting joint, a suction channel or a roll chamber, a comparatively low negative pressure, which is why correspondingly large flow cross sections must be provided.
  • this is readily possible due to the large area available at the bottom of the housing.
  • a plurality of air outlet openings is provided on the underside of the housing in order, on the one hand, to achieve a sufficiently large flow cross section and, on the other hand, to prevent a malfunction in the event of clogging of an air outlet opening.
  • a plurality of substantially identically formed air outlet openings arranged side by side. Basically, depending on the designs of the electric vacuum head and in particular the arrangement of the electric motor and air outlet openings seen in the working direction can be arranged in front of and behind the suction mouth, then passes over both Saugmundkanten each part of the entire cooling air into the suction.
  • the distance of the air outlet opening to the associated suction mouth edge is less than 30 mm, preferably less than 15 mm.
  • the at least one air outlet opening can expediently be arranged between the suction mouth and the sealing lip or the bristle strip.
  • a further pressure drop is also observed at the sealing lip or the bristle strip, so that there is a defined under normal operating conditions negative pressure between the sealing lip or the bristle strip and the associated suction mouth.
  • the channels, spaces and joints along the suction air flow between the suction mouth and the suction connection can be made particularly dense without impairing the cooling in order to minimize the occurrence of false air.
  • Rigid and articulated connections between the parts of the Elektrorosaugkopfes may be provided for example with seals or flexible connecting hoses.
  • the cooling air according to the invention contributes to the effective amount of air, a special high suction efficiency can be achieved even with a large demand for cooling air.
  • the electric motor can easily be designed for a maximum power consumption under load of more than 50 W, preferably more than 100 W, particularly preferably more than 200 W.
  • the at least one air outlet opening is arranged in a recess between preferably approximately perpendicular to the Saugmundkanten ribs.
  • cooling ribs and / or a fan wheel can be arranged on the electric motor to support the cooling.
  • the cross-section of the air inlet opening and / or the air outlet openings is designed to be adjustable, in order to enable an adaptation to a different demand for cooling air.
  • the adjustment of the cross section can be done manually or temperature controlled, wherein at a shutdown of the electric motor, the at least one air outlet opening or the at least one air inlet opening can be closed. It is also possible to variably increase or decrease the flow cross sections as a function of different functional and power settings of the electric motor.
  • an electrically or mechanically driven diaphragm can be provided.
  • an automatic temperature control by means of a temperature sensor or a bimetal-controlled aperture can be done.
  • a bypass is arranged on the engine compartment, which connects the engine compartment with a through-flow of the suction air channel or a through-flow of the suction chamber within the housing.
  • the bypass can expediently be pressure-controlled and closed during normal suction operation. If the suction air stream, for example, on a very langflorigem carpet or a clogged suction mouth decreases sharply, under certain circumstances, a sufficient cooling of the electric motor can no longer be ensured.
  • the negative pressure in the channels and chambers through which the suction air flows increases within the housing so that emergency cooling can be achieved by means of a bypass opening at a predetermined negative pressure.
  • a cleaning roller arranged in a roller space which has spirally arranged lips or brush strips, is preferably provided as the cleaning device.
  • the cleaning roller is usually aligned horizontally with its longitudinal axis perpendicular to the working direction of the Elektrorosaugkopfes.
  • a plurality of vertically or obliquely arranged to the processing direction cleaning rollers or other type of cleaning devices can be provided.
  • Fig. 1 shows an electrosuction head 1 according to the invention in a perspective view.
  • the electric suction head 1 has a housing 2 in which an electric motor 4 for driving a cleaning device 5 designed as a brush roller is arranged in an engine compartment 3.
  • the bristles of the brush roller pass through on the underside of the housing 2 extending over the width of the electrosuction head 1 and of a front Saugmundkante 6a and a rear Saugmundkante 6b limited suction mouth 7.
  • Sealing lips 8a, 8b are each in the direction of movement in front of the front Saugmundkante 6a and behind the rear suction mouth edge 6b arranged.
  • the electric suction head 1 has a suction connection 12 designed as a rotary tilting joint for connection to a suction pipe 13 or a vacuum cleaner housing.
  • the power supply of the Elektrorosaugkopfes 1 can be done without restriction via an integrated into the Elektrorosaugkopf 1 voltage source or via a supply line from the vacuum cleaner.
  • the electric suction head 1 is supported on its rear side by rollers 14.
