Definitions

  • This invention relates to a cleaning appliance, such as a vacuum cleaner.
  • a typical cylinder vacuum cleaner 1 comprises a main body 2 containing separating apparatus 3, such as a cyclonic separator or a bag for separating dirt and dust from an incoming dirty airflow.
  • the dirty airflow is introduced to the main body 2 via a suction hose 4 and a wand assembly 5, which is connected to the main body 2.
  • a cleaning tool 6 is attached to the remote end of the hose and wand assembly 4,5.
  • the main body 2 of the cleaner 1 is dragged along by the hose 4 as a user moves around a room.
  • a problem that may be encountered with conventional vacuum cleaners is that, in certain circumstances, the main body of the vacuum cleaner may become upset from the normal upright position shown in Figure 1. For example, if the user pulls upwardly on the hose when the cleaner is in use, the main body of the cleaner may tilt backwards, bringing the rear portion of the main body towards a floor surface. If the user continues to drag the cleaner along by the hose in this tipped-back position, damage may occur to the floor surface due to the rear portion bearing against, and being dragged along, the floor. Furthermore, use of the cleaner in the tipped-back position may be detrimental to the performance of the appliance.
  • the invention provides a cleaning appliance comprising a main body having a rear portion and means arranged to allow the main body to travel across a floor surface, the rear portion being spaced from the floor surface in normal use and having a wheel arranged so that, if the main body is tilted so that the rear portion is brought towards the floor surface, the wheel contacts the floor surface.
  • the provision of a wheel on the rear portion permits the cleaner to be pulled across a floor surface when the main body is in the tipped-back position, whilst preventing the rear portion from scraping against the floor. Thus, damage to the floor surface is prevented.
  • the wheel is arranged on the rear portion so that, in the tipped-back position, the centre of gravity of the main body acts to return the main body to its normal upright position. This may be effected by selection of the size, position and projection of the wheel. This feature ensures that the main body does not remain in a position that may cause the performance of the separating apparatus to be adversely affected.
  • wheel is intended to encompass rollers and rolling surfaces in general.
  • the wheel may be incorporated in a housing that is fixed with respect to the main body of the cleaner. Alternatively, the wheel may be permitted to swivel with respect to the main body.
  • cleaning appliance is intended to have a broad meaning, and includes a wide range of machines having a main body and a hose for carrying fluid to or from a floor surface. It includes, inter alia, machines which only apply suction to the surface, such as vacuum cleaners (dry, wet and wet/dry variants), so as to draw material from the surface, as well as machines which apply material to the surface, such as polishing/waxing machines, pressure washing machines and shampooing machines.
  • Figure 1 shows a conventional vacuum cleaner of the cylinder type
  • Figure 2 is a side view of a vacuum cleaner in accordance with an embodiment of the invention, with the hose omitted for clarity;
  • Figure 3 is a rear view of the vacuum cleaner of Figure 2.
  • Figure 4 is a side view of the cleaner of Figures 2 and 3 in a tipped-back position.
  • a cleaning appliance constructed according to the invention is shown in the form of a vacuum cleaner 7.
  • the vacuum cleaner 7 has a main body 8, which supports the main components of the vacuum cleaner.
  • the main body 8 has a chassis 9 which supports separating and collecting apparatus 10 and a motor-driven fan (not shown) for generating suction which draws dirt-laden air into the separating apparatus.
  • the main body 8 also has means for allowing the cleaner 7 to be moved across a floor surface 11.
  • two side wheels 12, one on each side of the chassis 9, are provided.
  • a further wheel in the form of a castor wheel 13 is provided, located beneath the front portion of the chassis 9.
  • the side wheels 12, and castor wheel 13 could be supplemented, or replaced, by other means for allowing the main body 8 to be moved across a surface, such as skids or rollers.
  • the separating apparatus 10 as a whole is removably mounted on the chassis 9 for emptying and for access to other components located beneath the separating apparatus.
  • the form of the separating apparatus 10 is not important to the invention. Whilst it is preferred to use cyclonic separators which spin dirt, dust and debris from the airflow, other forms of separator can be used. Examples of suitable separator technology include an inertial separator, a filter bag, a porous container, an electrostatic separator or a liquid-based separator.
  • a flexible hose (not shown for clarity) is connectable to an inlet port 14 on the main body 8.
  • Ducting forming part of the chassis 9 connects the air inlet port 14 to an inlet of the separating apparatus 10.
  • the inlet to the cyclonic separating apparatus 10 is arranged to guide an incoming airflow through an opening in the wall of the cyclonic separator in a tangential manner.
  • the precise details of the ducting and the cyclonic separator 10 are immaterial to this invention.
  • the other end of the flexible hose is connectable to a wand, such as the wand 5 shown in Figure 1.
  • the distal end of the wand 5 is adapted to adapted to receive a floor tool, such as the floor tool 6 shown in Figure 1, in any known manner.
  • a single continuous hose-receiving channel 15 is provided along the sides and back of the periphery of the chassis 9.
  • the hose-receiving channel 15 defines part of a storage path for the hose and serves to guide and support the hose when it is stored.
  • Channel 15 has a semicircular shape along most of its length and a diameter that is just greater than the hose that it retains.
  • the main body 8 of the cleaner is pulled along the floor surface 11 by the hose as a user moves around a room.
  • the hose has a construction which is robust enough to withstand this pulling action and any normal abrasion, which may be encountered as the hose rubs against obstacles in a room.
  • the air inlet port 14 is centrally mounted on the main body 8 at the forward, lower part of the machine.
  • the air inlet is not centrally positioned, such as the machine shown in Figure 1 where the inlet is near the upper part of the separating apparatus 3, it is preferable to anchor the hose 4 to the machine at a central position (as with anchor point 16 in the machine shown in Figure 1) so that when a user pulls the hose, the main body 2 follows the user.
  • the main body has a rear portion 17, which, in normal usage of the vacuum cleaner, is spaced from the floor surface 11 to be cleaned.
  • the rear portion 17 has a surface 18 that is generally transverse to the plane of the floor surface 11.
  • the rear portion 17 includes part of the hose-receiving channel 15 and a storage area 19 for tools 20, 21, 22, which are connectable to the distal end of the hose or the wand.
  • the vacuum cleaner 7 may become upset from the upright position shown in Figures 2 and 3.
  • the main body 8 may tilt backwards, bringing the rear portion 17 towards the floor surface 11.
  • the user may choose to continue to use the cleaner 7 in this tipped-back position and pull it along the floor.
  • the cleaner 7 travels across the floor by means of the side wheels 12 that remain operable in this tilted position. This may result in damage to the floor surface 11, or parts of the cleaner itself, particularly those carried by the rear portion 17 of the main body.
  • operation of the separating apparatus 10 in this position may be detrimental to its performance.
  • the rear portion 17 of the main body 8 carries a wheel 23.
  • the wheel 23 contacts the floor, as illustrated in Figure 4.
  • This rear wheel 23 permits the user to continue to pull the cleaner 7 along in the tipped-back position without causing damage to the surface 11 of the floor.
  • the cleaner 7 travels across the floor surface 11 by means of the rear wheel 23 and the side wheels 12.
  • the size, position and projection of the wheel 23 are selected so that, in the tipped- back position, the wheel projects beyond any other rearwardly-projecting parts of the main body 8.
  • the hose-receiving channel 15 and tool storage area 19 do not bear against the floor surface 11 when the cleaner is in the tipped-back position.
  • the wheel 23 also provides protection for parts of the cleaner when in storage.
  • the position of the hose when stored on the cleaner is indicated by the broken lines 25.
  • the provision of the wheel 23 on the rear surface 18 ensures that the hose is spaced from a floor surface if the main body 8 is tilted when the cleaner is not being used. This prevents the hose from being damaged by the weight of the cleaner 7 bearing down upon it.
  • the size, position and projection of the wheel 23 are also arranged so that, when the cleaner is tilted backwards, the centre of gravity of the main body 8 does not act outside the base of the main body.
  • the base of the main body 8 is defined by the side wheels 12.
  • the rear wheel 23 has a housing 25 that is fixed with respect to the rear portion 17 so that the rotational axis of the rear wheel is substantially parallel to that of the side wheels 12.
  • Other arrangements may be possible, such as a castor wheel capable of swivelling motion.
  • the rear wheel 23 need not be associated with a housing 24, but could instead be located on an axle that forms an integral part of the surface 18 of the rear portion 19 of the appliance.
  • the rear wheel 23 may be retractable for storage of the cleaner, for example. Naturally, a plurality of wheels or other rolling surfaces may be provided.
  • the invention has been described with reference to a cyclonic cylinder vacuum cleaner, but may be applied to other forms of vacuum cleaner and other cleaning appliances.

Abstract

L'invention concerne un appareil à nettoyer, tel qu'un aspirateur à forme ronde (7), qui comprend un corps principal (8) présentant une partie arrière (17) et des roues latérales (12) arrangées de manière à permettre au corps principal de se déplacer sur une surface de plancher (11). Pendant l'utilisation normale, la partie arrière est décalée de la surface de plancher. La partie arrière comporte une roue (23) disposée de sorte que, lorsque le corps principal est basculé entraînant la partie arrière vers le plancher, la roue vienne au contact de la surface de plancher. Ainsi, l'aspirateur peut être utilisé dans une position inclinée vers l'arrière sans endommager la surface de plancher pendant que l'aspirateur est traîné par l'usager au moyen d'un tuyau souple fixé au corps principal. La taille et la position de la roue sont déterminées de sorte que, lorsque l'aspirateur est incliné vers l'arrière, le centre de gravité du corps principal agit de façon à remettre ce dernier dans sa position normale.
