Definitions

  • This invention relates to a vacuum cleaner.
  • Vacuum cleaners commonly have a filter or porous paper filter bags for collecting the dirt and dust picked up by the vacuum cleaner. Hitherto these bags have been made from paper, and when the bag is full it has to be discarded and replaced by a new bag.
  • a disadvantage of one known cyclonic cleaner lies in the fact that, to achieve the level of filtration demanded in modern vacuum cleaners, the cyclonic separator must be supplemented by filters disposed between the cyclone and the motor/fan unit, and between the motor/fan unit and the exhaust outlet of the cleaner. These filters can require frequent renewal, and can be expensive to purchase.
  • GB 1049292 discloses one such vacuum cleaner comprising a reusable and washable dirt receptacle.
  • the receptacle is of multi-layer plastic foam construction and is of cylindrical form with an open end towards the dirty air inlet.
  • the receptacle is formed of flexible material and may be squeezed dry following washing.
  • GB 2265096 discloses another such vacuum cleaner comprising a reusable dirt receptacle, the Hoover receptacle comprising a thin, flexible sintered plastics bag, having a removable lid, and supported within a rigid plastic cage.
  • a vacuum cleaner comprising a rigid one-piece dust receptacle formed of a moulded porous plastics material and removably mounted within a cavity in a body of the cleaner, and an inlet for dust laden air communicating with the interior of said receptacle.
  • the moulded porous plastics material is a sintered material.
  • the moulded porous plastics material is a high density polyethylene material, which is preferably ground and sintered.
  • the dust receptacle is substantially rectangular or square in cross-section.
  • spacers extend between the wall(s) of the dust receptacle and the wall(s) of the cavity in which the dust receptacle is mounted.
  • an air gap can be provided around the external surface of the dust receptacle, which air gap is evacuated by the fan of the vacuum cleaner during use.
  • air drawn through the dust receptacle is not concentrated in one area of its surface to provide a more even distribution of dust on the internal surface of the dust receptacle.
  • the spacers whilst serving to locate the dust receptacle also help to prevent outward deformation of the wall (s) of the dust receptacle due to the pressure drop created across the wall(s) of the receptacle.
  • the spacers are integral formations on the dust receptacle.
  • the dust receptacle is provided with an opening through which the collected dirt and dust can be emptied.
  • porous paper filter bags have been virtually universally used as the dirt receptacles in modern vacuum cleaners, with much attention being paid to means of retaining the dust and dirt within the bag during removal of the bag from the appliance and during its subsequent disposal in the dustbin.
  • a disadvantage of cyclonic vacuum cleaners is that the full dirt receptacle must be carried from the cleaner to the point of disposal in an open state, whereby its contents are not effectively contained and indeed, may be spilled and/or blown into the atmosphere during transport and emptying.
  • Some currently available dual cyclonic cleaners suffer the further disadvantage that dismounting of the dirt receptacle is a complex and dirty operation, since the cyclonic separation components are partly contained within the receptacle.
  • the opening in the dust receptacle of the present invention is preferably provided with a closure which can be removed from the body of the cleaner together with the duet receptacle, in order to contain the dirt and dust whilst the receptacle is taken to be emptied.
  • the body of the cleaner comprises an external housing, a removable portion of the housing forming said closure.
  • a catch is provided for locking the removable portion of the housing to the remainder of the body of the cleaner when the cleaner is in use.
  • a catch is provided for securing the removable portion of the housing across the opening in the receptacle, for at least the period during which the receptacle is being taken to be emptied.
  • a single actuator is provided for operating both catches.
  • the actuator is preferably arranged such that, in a first position, the removable portion of the housing is locked to the remainder of the body of the cleaner and, in a second position, the removable portion of the housing is unlocked from the remainder of the body of the cleaner and secured across the opening in the receptacle.
  • both catches are provided on a latching mechanism mounted to the removable portion of the housing, the mechanism comprising oppositely directed portions arranged to be urged apart when the actuator is moved to said first position, so as to engage the remainder of the body of the cleaner and arranged to be urged towards each other when the actuator is moved to said second position, so as to engage the receptacle.
  • a handle is provided on the removable portion of the housing for carrying the receptacle to the point where it is to be emptied.
  • the actuator forms said handle when in said second position.
  • the actuator is recessed in the removable portion of the housing when in said first position.
  • the outer surface of the receptacle can become contaminated with fine dust during use. Accordingly, the receptacle is preferably provided moulded with at least one handgrip which enables the user to empty the receptacle without actually touching its outer surface.
  • Means are preferably provided within the cavity of the cleaner to obscure the gripping surface of the or each handgrip when the receptacle is fitted within the cavity and/or to wipe the or each handgrip of dust as the receptacle is removed from the cavity for emptying.
  • a vacuum cleaner comprising a dust receptacle removably mounted within a cavity in a body of the cleaner and having an opening through which the dust collected therein can be emptied, an inlet for dust laden air communicating with the interior of the receptacle, and an external housing, a removable portion of the housing forming a closure for the opening when the dust receptacle is removed from the body of the cleaner for emptying.
  • FIG. 1 & 2 of the drawings there is shown the body portion of a so-called canister-type vacuum cleaner.
  • a dirty air inlet aperture 10 is provided in the front of the body portion of the cleaner for connecting to a cleaning tool via an elongate flexible suction hose.
  • the dirty air inlet aperture 10 communicates with a passage 11 leading to an internal cavity 12 within the body of the cleaner, in which a removable dust receptacle 13 is mounted.
  • the vacuum cleaner comprises an external moulded plastics housing 14 having top and bottom walls, and opposite end and side walls. As will be described, a portion of the top wall of the housing is removable (as shown in Figure 2) and forms a closure 15 for the dust receptacle 13.
  • the dust receptacle 13 comprises a one-piece moulding of a porous sintered plastics material, formed by sintering 400 micron ground particles of high density polyethylene.
  • the one-piece moulding comprises a rigid bottom and opposite side and end walls (16-19), and an opening in its top.
  • An externally projecting lip 21 extends around the upper end of the periphery of the receptacle, parallel to the upper edges of the side and end walls (17-19) thereof.
  • An aperture 20 is provided in the front end wall 19 of the receptacle 13 which, in use, sealingly communicates with the dirty air inlet passage 11 by means of a grommet of resilient material fitted to the aperture 20.
  • a pipe (not shown) may be provided within the receptacle to communicate air from the aperture 20 to the upper region of the receptacle 13, thereby preventing accumulated detritus in the base of the receptacle from escaping back through the dirty air inlet passage 11.
  • the receptacle 13 in use, is mounted in the cavity 12 inside the body of the cleaner, where the opening in its top is sealed against the closure 15 by a seal 23.
  • Projections 30 on either side of the receptacle 13 locate within respective channels on either side of the cavity 12 to locate the receptacle 13 therein and to maintain an air gap around the sides of the receptacle.
  • the base of the receptacle 13 is also formed with feet 31 at each of its four corners, which rest upon the floor of the cavity to maintain an air gap below the receptacle.
  • a handle 24 is provided on the upper surface of the closure 15 for operating a lock mechanism 25 which either secures the closure 15 to the rest of the housing 14 or to the dust receptacle 13.
  • the handle 24 is normally disposed in a recess 26 formed in the upper surface of the closure 15, so that the handle blends with the shape of the upper wall of the housing 14.
  • the lock mechanism 25 comprises a pair of oppositely-directed arms 27 slidably mounted to the underside of the closure 15.
  • the inner ends of the arms 27 are connected to a cam 28 mounted on the shaft 29 of the handle 24, such that rotation of the handle through 90° causes the arms 27 to move from an extended position to a retracted position, as will be described in further detail.
  • the handle 24 When the dust receptacle 13 becomes full, it can be removed from the vacuum cleaner for emptying and washing. However, before this is done, the handle 24 must be operated to unlock the closure 15 from the body of the cleaner.
  • the lower end of the shaft 29 of the handle engages the cam 28, such that rotation of the handle through 90°, retracts the arms 27, thereby disengaging them from the body of the cleaner.
  • the outer ends of the arms 27 are cranked downwardly through 90° and are each provided with oppositely-directed projections 32,33 which respectively engage the cleaner body, when the arms 27 are extended, and the lip 21 on the receptacle 13, when the arms 27 are retracted.
  • the handle 24 when the handle 24 is raised and turned, the arms 27 disengage the body of the cleaner and engage the dust receptacle, as shown in Figure 4C. In this position, the handle 24 can be used to lift the closure 15 and receptacle 13 from the body of the cleaner, as shown in Figure D.
  • the assembly can then be carried to a point where the receptacle 13 can be emptied. It will be appreciated that the closure 15 serves to prevent any dust etc. from escaping from the receptacle 13 whilst it is being carried.
  • the handle 24 is turned back through 90° thereby extending the arms and releasing the receptacle 13.
  • the receptacle 13 is provided with integral handgrips 22, as shown in Figure 3, which enable the receptacle 13 to be held and emptied without having to touch the external walls of the receptacle 13, which may be dusty.
  • Means (not shown), such as foam pads, may be mounted within the cavity of the body of the cleaner for obscuring the gripping surfaces of the handgrips 22 when the receptacle 13 is fitted within the cavity 12 and for wiping the handgrips 22 clean as the receptacle 13 is removed from the body of the cleaner.
  • the receptacle of the vacuum cleaner in accordance with this invention is more efficient at filtering dirt and dust than conventional bagless cleaners but yet is inexpensive to operate, since the receptacle can be emptied and re-used almost indefinitely.
  • the receptacle can be washed occasionally. Accordingly, the material of the receptacle is preferably treated with a hydrophilic substance to encourage the absorption of water by the material (sintered plastics materials being inherently hydrophobic).
  • the material of the receptacle may also be treated with an anti-bacterial substance.
