Definitions

  • This invention relates to a surface cleaning apparatus.
  • a surface cleaning apparatus including:
  • an elongate member having an elongate axis (B), said elongate member connecting the floor head to the housing, said elongate member including a passage for carrying dirt-laden air from the floor head to the dirt collection container,
  • a surface cleaning apparatus including:
  • an elongate member having an elongate axis (B), said elongate member connecting the floor head to the housing, said elongate member including a passage for carrying dirt-laden air from the floor head to the dirt collection container,
  • FIG. 1 is a perspective view of a surface cleaning apparatus
  • FIG. 2 is a front view of the apparatus of FIG. 1 ;
  • FIG. 3 is a side view of the apparatus FIG. 1 ;
  • FIG. 4 is an opposite side view of the apparatus FIG. 1 ;
  • FIG. 5 is a perspective view of a housing of the apparatus of FIG. 1 , which housing is operable as a handheld surface cleaning apparatus;
  • FIG. 6 is a side view of the housing of FIG. 5 ;
  • FIG. 7 is an opposite side view of the housing of FIG. 5 ;
  • FIG. 8 is a cross-sectional view of the housing from the same side as shown in FIG. 6 .
  • the apparatus 10 includes a floor head 12 , a housing 16 and an elongate member 14 , having an elongate axis B, connecting the floor head 12 to the housing 16 .
  • the housing 16 in this example is operable as a handheld surface cleaning apparatus, commonly known as a hand vac, when the elongate member 14 and floor head 12 are not connected thereto.
  • the housing 16 supports a suction source, a dirt container 18 and a cyclonic separator.
  • the suction source is an electric motor driving a rotatable fan, but any appropriate suction source may be used. All that is necessary is for the suction source to be able to draw air through the floor head 12 and elongate member 14 towards the dirt collection container.
  • the housing 16 supports or contains a battery to provide electrical power to the suction motor and other components of the apparatus 10 .
  • the apparatus 10 may be mains powered.
  • the apparatus 10 includes a cyclonic separator to separate dirt from the air flowing through the apparatus 10 , this is not essential. Indeed, embodiments are envisaged where the apparatus 10 includes a filter bag which collects dirt, or any other appropriate device to separate the dirt from the air.
  • the apparatus 10 includes a pivotally moveable door 18 a which enables a user to empty dirt collected within the container 18 .
  • the elongate member 14 includes a passage for carrying dirt-laden air from the floor head 12 to the dirt collection container 18 .
  • the floor head 12 includes a motor for driving a rotatable floor agitating member or brush, so the elongate member 14 includes a further passage through which electrical cables may extend to provide an electric connection between the housing 16 and the motor in the floor head.
  • the floor head 12 is disconnectable from the elongate member 14 , so that, for example, another tool can be connected to the free end of the elongate member 14 .
  • the elongate member 14 is also disconnectable from the housing 16 , by way of a manually operated switch 17 . This enables the housing 16 to be used as handheld surface cleaning apparatus, with the option of being able to connect another tool to the location from where the elongate member 16 is removed.
  • the housing 16 includes a handle for holding the apparatus 10 , said handle including first 20 and second 21 user-graspable portions which are connected to each other substantially at right-angles.
  • a first end of the first user-graspable portion 20 is connected to the housing 16 and extends generally rearwardly away therefrom and from the elongate member 14 .
  • a first end of the second user-graspable portion 21 is connected to the housing 16 and extends generally upwardly therefrom.
  • Respective second ends of the first 20 and second 21 user-graspable portions are connected to each other.
  • the first 20 and second 21 user-graspable portions form a handle which is L-shaped and which provides two locations each of which is sized such that it can be grasped fully by a hand of a user.
  • a device 22 e.g. a switch, for turning the apparatus “on” is positioned at the connection of the second ends of the first 20 and second 21 user-graspable portions to each other.
  • the dirt collection container 18 is generally cylindrical and has an elongate axis A. Within the dirt collection container 18 is positioned a cyclonic separation device which also has an elongate axis coaxial with the axis A, the axis A being that about which dirt-laden air is caused to rotate as it passes through the apparatus 10 .
  • the elongate axis A is substantially horizontal in normal use. Whilst in this embodiment the elongate axes of the dirt collection container 18 and the cyclonic separation device are coaxial or substantially coaxial, they need not be. They could, for example, be parallel and offset from each other or inclined relative to each other.
  • the elongate axis B of the elongate member 14 intersects or substantially intersects the elongate axis A of the dirt collection container 18 , with the two axes intersecting substantially at right angles.
  • the axes A and B are perpendicular or substantially perpendicular to each other.
  • the elongate axis of the cyclonic separator is coaxial with the axis A, in the present embodiment, the elongate axis B of the elongate member 14 also intersects or substantially intersects the elongate axis A of the cyclonic separation device.
  • This aligning of the axes A and B provides for improved handling of the apparatus 10 , especially, although not exclusively, in the configuration where the elongate member 14 is connected to the housing 16 , because of improved weight distribution. Also, the intersecting of the axes A and B in combination with the two part handle arrangement provide for improved weight distribution and handling whether the first 20 or second 21 user-graspable portion is being held. Further, the intersecting and alignment of the axes A and B ensures that air flowing from the elongate member 14 or tool (whichever is connected to the housing 16 ) can travel in an efficient and shorter path to the cyclonic separator device, thus improving separation efficiency and performance.
  • the handle of the device i.e. the first 20 and second 21 user-graspable portion
  • the handle of the device is formed in a plane that lies substantially parallel to axis B, and preferably coincident with axis B.
  • the handle is preferably central relative to the width of the device, and in embodiments the user-graspable portions extend rearwardly and downwardly.
  • the axis A lies perpendicular to the plane of the handle, i.e. it is disposed across the width of the device, rather than lengthwise or vertically. Therefore, in embodiments and as shown, the axis A lies substantially perpendicular to the plane in which the handle and axis B both lie, which—in normal use—is typically substantially horizontal.
