Description
- This invention relates to suction cleaners (“vacuum cleaners”) of the cylinder type (sometimes also referred to as the canister type since very few modern such cleaners are cylindrical).
- A suction cleaner of the cylinder type comprises a main-unit whose body contains a source of suction, i.e. a motor and an impeller for creating a suction airflow, together with a separator which separates entrained collected dust, dirt and other debris (all herein referred to as dust) from the airflow and retains it for subsequent disposal. The separator may include one more cyclonic separators in which the dust is separated from the airflow by centrifugal force, and/or one or more filters. A flexible hose for the suction airflow is used to connect the main unit to a cleaning head of whatever type is appropriate for the surface which is to be cleaned. A cleaner may be provided with a number of different cleaning heads/tools for different cleaning jobs. A floor cleaning head, e.g. a carpet or a hard floor cleaning head, characteristically is connected to the flexible hose with the intermediary of a rigid tubular wand (which may be telescopically adjustable in respect of its length) which renders it easy for a user who is standing upright to work the cleaning head over a floor or other surface. Other tools for other cleaning purposes may be used with a wand.
- It will be appreciated from the above that a cylinder type suction cleaner comprises several parts most notably the flexible hose, wand and one or more cleaning heads which can be relatively bulky and thus can present a storage problem when the cleaner is not in use. Often the main unit, if it is of a design which is intended to work primarily in a generally horizontal orientation, is able to be stood on one end so as to reduce its footprint, i.e. the area of floor space it occupies, but storage space still has to be found for the hose, wand, and one or more cleaning heads.
- It has been proposed, in EP 0887040 A and U.S. Pat. No. 5,836,047 for example, that a suction cleaner may be usable in both upright and canister modes. A conventional upright cleaner comprises a first body part which is movable over a floor surface and constitutes or is provided with a cleaning head, and a second body part which is connected to the first and usually accommodates the motor and fan unit of the cleaner and the separator/dust collector. Usually the two body parts are pivotably connected together, so that the second body part may extend in a generally upright orientation or at an inclination to the floor surface which is to be cleaned. In the dual mode cleaners disclosed as aforesaid, the main unit of a cylinder cleaner is able to be used in an upright or inclined orientation with the wand fixed to it to form a handle, and the cleaning head separately connected to the main unit to be movable over a floor surface. When used in this mode, however, the footprint of the cleaner is still relatively large and hence the problem of compact storage is not solved.
- Accordingly it is an object of the present invention to provide a suction cleaner of cylinder type wherein the problem of compact storage is addressed.
- According to one aspect of the invention, we provide a suction cleaner of the cylinder type comprising a main unit including a source of suction and a dust separating/collecting means; a flexible hose; a wand, and a cleaning head; wherein the main unit is able to be stood on its end and there is releasable catch means providing for the wand with cleaning head attached to be releasably connected to the main unit.
- Preferably the wand is, when connected to the main unit, usable as a handle for lifting and moving the main unit. To this end, the releasable catch means by which the wand is connectable to the main unit must have sufficient strength to support the main unit from the wand.
- When connected to the main unit as aforesaid, part of the wand may lie within, or partially lie within, a recess provided in the main unit. Such recess may lie in the underside of the main unit, which faces the floor surface on which the main unit stands in normal use (although it is to be appreciated that the main unit may also be usable when stood on its end, for example when cleaning stairs).
- The catch means may comprise first inter-engaging catch formations provided respectively on the main unit of the cleaner and on the cleaning head (or a wand part in the vicinity of the cleaning head), and second catch formations provided respectively on the main unit and on the wand spaced therealong from the cleaning head. A suitable spacing of such first and second catch formations enables the wand to be connected to the main unit sufficiently securely to use it as a handle as aforesaid.
- The second catch formations may be engageable by an upward movement of the wand relative to the main unit (having regard to the orientation of the latter when it is stood on its end). They may comprise a downwardly facing recess or recesses on the main unit of the cleaner and a complementary projection or projections on the wand, engageable in the recess or recesses. The first catch formation on the main unit of the cleaner may comprise a catch member facing upwardly to engage a complementary member or formation on the wand or head, and spring biased to bias the wand upwardly and urge the second catch formations into firm engagement.
- Such engagement of the first and second catch formations may entail placing the respective first catch formations in engagement with one another and then pressing the wand downwardly to displace the catch member on the main body downwardly until the projection(s) constituting the second catch formation(s) on the wand are in a position to enter the recess(es) forming the second catch formation on the main body. The wand is then moved upwardly by the spring biased catch member on the main body. Release of the wand from the main body is, of course, the reverse of this process.
- The second catch formation(s) on the main body of the cleaner may be provided in association with a castor assembly beneath the main unit, the main unit being movable over a floor surface in normal use on such a castor assembly together with wheels provided at or adjacent the end of the main unit on which it is able to be stood.
- These and other features of the invention will now be described by way of example with reference to the accompanying drawings, of which:—
-
FIG. 1 is a diagrammatic perspective view illustrating a wand and cleaning head positioned in relation to a main unit of a cylinder type of suction cleaner, in accordance with the invention; -
FIG. 2 is an enlarged view similar to that ofFIG. 1 , showing the respective catch formations on the wand/cleaning head and the main unit of the cleaner; -
FIGS. 3 a, b and c illustrate the engagement of the catch formations; -
FIG. 4 is a side elevation, showing the main unit of the cleaner with wand and cleaning head connected thereto. - Referring firstly to
FIG. 1 of the drawings, this shows a suction cleaner of the cylinder type which comprises amain unit 10 with abody 11. Thebody 11 accommodates a source of suction, namely an electric motor and an impeller for creating a suction airflow, and a separator arrangement for separating from the suction airflow dust which has been collected and entrained in the airflow, and retaining it for subsequent disposal. The separator may include one or more cyclonic separators in which the dust is separated from the airflow by centrifugal force, and/or one or more filters. Part of a cyclonic separating device is indicated at 12. - The
body 11 is of somewhat elongated form, and is shown in the drawings standing in an upright attitude on its one end. At this end it is provided with a pair ofwheels 13 by which it is able to be moved over a floor or other surface in use, when it is intended to be in a generally horizontal orientation with anunderside 14 of the body facing such surface. Towards the opposite end of the body from that at which thewheels 13 are provided, the underside of the body is provided with a castor assembly indicated generally at 15 to facilitate its movement over the surface. - Also shown in
FIG. 1 is a wand assembly indicated generally at 16 comprising a rigidtubular wand 17 at one end of which ahandle assembly 18 is connected and at the opposite end of which acleaning head 19 is connected. The wand may be telescopically extendible and able to be fixed at a required length to make it easy for a user holding thehandle 18 to work the cleaning head over a floor surface. Thehandle 18 provides a pivotal connection at 19 for a flexible suction hose (not shown) extending to themain unit 10. The suction hose may connect to themain unit 10 at a detachable connection for example at the front end of thebody 11 as indicated at 21, or could be arranged to be deployed as required from, or retracted to, a hose storage reel incorporated in thebody 11. - Referring now to
FIG. 2 of the drawings, this shows in greater detail a lower end part of thewand 17 and thecleaning head 19 fitted thereto. The cleaning head has aconnection part 24 which is fitted to the wand by a plug-in connection, and apart 25 which may incorporate a rotatable brush/beater bar drive driven by an electric motor or by a turbine device powered by the suction airflow through the cleaning head. In the case of an electrically driven brush/beater bar, thehandle 18,wand 17 and connectingpart 24 will be required to provide for transmission of electrical power to the cleaning head. Thepart 25 is connected to thepart 24 for pivotal movement about a transverse axis. More or less beneath the pivotal connection between theparts wheels 26 on which the cleaning head is movable over a surface being cleaned and, rearwardly of thewheels 26, there is atransverse bar 27 for the purpose described hereafter. - The
castor assembly 15 comprises abody 29 carrying a pair ofcastor wheels 30 spaced transversely of one another, thebody 29 being pivotable relative to thebody 11 of the cleaner about an upright axis when the cleaner is in its normal operative orientation supported on a floor or other surface by itswheels wheels 30 thecastor body 29 defines avalley 31 able to accommodate thewand 17, and on either side of thevalley 31 there are catch formations in the form of downwardly-facing (when the castor body is in the illustrated orientation)recesses 32. - Beneath the
castor assembly 15 when thecleaner body 11 is stood on its end as illustrated, there is an upwardly facing somewhat hook-shaped catch member 34. This is spring biased upwardly, being displaceable downwardly in the direction ofarrow 35 against suction spring biasing. - A part-
cylindrical recess 39 is provided in theunderside 14 of thebody 11 of the cleaner main unit, extending from thecatch member 34 to and slightly beyond thecastor assembly 15. When the castor assembly is in the orientation illustrated, therecess 39 aligns with thevalley 31 in thecastor body 29. In the vicinity of thecatch member 34, to opposite sides thereof and slightly therebeneath when thebody 11 of the cleaner is stood on end as illustrated, there arerecesses 36 able to accommodate thewheels 26 of thecleaning head 19. - Spaced upwardly of it from its end connected to the
cleaning head 19, the wand has a member 37 provided with opposed transversely outwardly projecting catch formations in the form of pins, one of which is indicated at 38. Themember 34 andtransverse bar 27 constitute first cooperable catch formations, and therecesses 32 andpins 38 constitute second cooperable catch formations, together providing for the wand, with cleaning head attached, to be connected to the body of the main unit. Such connection is illustrated inFIG. 3 . - The three views,
FIGS. 3 a, 3 b and 3 c, each show the hook-shaped member 34, pivotally mounted and spring biased upwardly by a biasing spring 34 a. They also show thecastor body 31 with itsrecesses 32. On thewand 17 they show the transversely outwardly extendingpins 38, and on thecleaning head 19 thetransverse bar 27. To connect the wand to the main unit, with the latter standing on its end, the cleaning head is presented to the unit such that itstransverse bar 27 engages thecatch member 34. Downward pressure on the wand displaces thecatch member 34 downwardly against the force of its biasing spring until thepins 38 are able to enter and engage therecesses 32 in thecastor body 31. When the downward pressure on the wand ceases, the spring 34 a biases themember 34 upwardly so that thepins 38 fully enter therecesses 32 so as to be held captive therein. The wand is then securely fitted to the main unit of the cleaner, and can be used to lift the latter. -
FIG. 4 of the drawings shows the cleaner with the wand fitted to the main unit as aforesaid. Thewand 17 lies partially in therecess 39, andvalley 31 of the castor assembly. It will be noted that thepart 25 of the cleaninghead 19 lies closely adjacent thebody 11 of the main unit, so that this configuration of the cleaner not only presents the advantage of being easily able to be moved using the wand as a handle, but also has a small footprint for storage purposes. The flexible suction hose which in use of the cleaner connects the wand to the main unit may be disconnected or left connected, as required. When the cleaner is to be used, removal of the wand from the main unit is the reverse of the above-described connection procedure. - In the present specification “comprises” means “includes or consists of” and “comprising” means “including or consisting of”.
- The features disclosed in the foregoing description, or the following claims, or the accompanying drawings, expressed in their specific forms or in terms of a means for performing the disclosed function, or a method or process for attaining the disclosed result, as appropriate, may, separately, or in any combination of such features, be utilised for realising the invention in diverse forms thereof.
