Definitions

  • This invention relates to vacuum cleaners and more particularly to new and improved means for the cooling of the motor., The invention is applicable to a vacuum cleaner in which the' uum cleaner in which both air-streams are mixed and lead through one and the same fan.
  • Fig. 1 is a sectional view of a vacuum cleaner according to the invention
  • Air is drawn in through hose '30 sioned with respect to motor I 9 and casing I0 that in operative position it will press a part of the dust separating member 25 against the bottom of casing III.
  • That part of casing IIl which is surrounded by the'lower edge of mem- 40 ber 32 is provided with perforations 33, said part being bent slightly downwards.
  • the part of member 25 surrounded by the lower edge of member 32 has been denoted with reference character 34.
  • the bottom of casing I0 is bent in- 45 wards as at 35 and is provided with a radially extending channel 36, to enable air to enter perforations 33 even if the cleaner rests on the floor ⁇ or the like.
  • a vacuum cleaner comprising a casing, means dividing said casing into a dust separation chamber, a fan chamber and a motor chamber, a fain in said fan chamber, a motor in said motory chamber connected to rotate said fan member, and means providing a direct path from outside said casing for ow of air past said motor to cool the motor, said fan chamber having a single inlet opening on one ,side thereof com-A municating with said dust chamber, and said path of ow being in direct communication with said inlet opening whereby air is drawn through said path of iiow and through said inlet opening into said fan chamber, said inlet opening affording access of air to the entire blade surface of the fan.
  • a pneumatic cleaner comprising, in combination, a hollow casing having stiff walls and a 75 cover, a iilter cell supported within said casing and spaced from the casing walls to dene a litter-chamber, a motor in said cell, a pump spaced from and driven by said motor and having its inlet communicating with the interior of said lter-cell and its outlet through said cover, said motor being located opposite to the inlet of said pump, and a suction-connection carried by said cover communicating with the space inside said casing and outside said filter-cell.
  • a pneumatic cleaner comprising, in combination, a Ahollow casing having stii walls, a pump carried by one wall having an inlet inside said casing and an outlet outside said casing, a motor in said casing spaced from and operatively connected to said pump, said inlet being located be tween said pump and said motor, a lter-'cell inside said casing surrounding said motor and communicating with said inlet, said filter-cell defining a chamber about said motor to which litter has no access, a hose connection communieating with the Vspace between said lter-cell and the casing wall, and a distending frame inside said lter-cell'.
  • a pneumatic cleaner comprising, in combination, an upright dust receptacle having im E periorate walls, a removable cover for said receptacle, means detachably securing said cover to said receptacle, a suction pump carried by said cover and having an inlet and an outlet, an electric motor operatively connected to said pump in l0 spaced relation in front of the inlet opening thereof, a filtering element of pervious material car ried by said receptacle and depending into said receptacle and spaced from the walls thereof, the inner Wall of said ltering element defining a l5 suction chamber and communicating with said inlet, and the exterior thereof defining with said receptacle a litter chamber, and a hose connection carried by said cover and communicating with said litter-chamber.
  • a vacuum cleaner a casing formed with a dust ladened air inlet and a clean air outlet, a dust separating member in said casing having a portion disposed between said inlet and said outlet, a motor, means providing a path of ow 25 of air independently of said dust ladened air inlet from the atmosphere past said motor, another portion of said dust separating member being disposed across said path of flow between the atmosphere and said motor, and means driven 30 by said motor for producing flow of air through said dust ladened air inlet,-said dust separating member and said outlet, and for producing an independent flow of air through said path of flow.
