detailed description

Referring first to FIGS. 1-21 , these illustrate a first embodiment of a surface cleaning apparatus 10 embodying many aspects of the present invention. Briefly, device 10 includes a body 12 , a first wheel 14 at a first end of body 12 , and a second wheel 16 at an opposite second end of body 12 . The wheels are rotatable about respective wheel axes. The body 12 is generally cylindrical and has a generally elongated axis A extending along the longitudinal length of the body 12 between the wheels 14 , 16 .

The body 12 is shaped such that its outer surface, which extends circumferentially around the axis A, is generally concave. In more detail, in this particular embodiment, the body 12 has a central region C with respective side portions R, L situated between the central region C and each wheel 14 , 16 . It can be seen from the figures that the radius Y of each part R, L increases as the outer surface of the part extends from the central region C towards each wheel 14, 16, in other words, the parts R, L increase as they move towards the wheels 14, 16. Extend and expand outward.

It will be appreciated that the shape of the body 12 ensures that a generally concave portion is provided on the floor-facing portion of the outer surface of the body 12 when the device is positioned on the floor surface F when the two wheels 14, 16 contact the floor surface F , the generally concave portion provides a space S. Space S provides a space/recess for biasing means 80, which will be discussed in more detail below.

Although in the present example, body 12 is generally symmetrical about a plane extending transversely through central portion C and axis A, it should be understood that other shapes for body 12 may be employed without departing from the scope of the present invention. It need not be the case that the outer surface of the body 12 is generally symmetrical about the axis A. For example, the body 12 may be shaped such that a space S is provided between the body and the floor surface F, without the upwardly facing surface of the body 12 being provided with any concave portions or the like (eg it may be convex). In this particular example, it is advantageous that the radii of the ground engaging surfaces of the first wheel 14 and the second wheel 16, when measured transversely to the axis A, are greater than the maximum width of the body. This ensures that the body does not soil the floor surface F when the device is in use.

The main body 12 houses the suction motor 140, the suction fan 150, the first cyclone separator device 110, the second cyclone separator device 210 and the chamber 100 for receiving and storing dirt. The location and shape of these component parts and their interaction are discussed in more detail below. The main body 12 is made of a plastic material such as acrylonitrile-butadiene-styrene (ABS). The material is opaque, but it could also be made of a translucent or transparent material to allow the user to be given a visual indication of the level of contamination within the chamber 100 . The wheels are made of rubber material.

While in the present embodiment the wheels 14, 16 are rotatable about axes that are coaxial with each other and with the axis A of the body 12, this need not be the case. For example, an embodiment in which the axis of rotation of the wheel is offset from the axis A is conceivable. Embodiments are also conceivable in which the axis of rotation of the first wheel and the axis of rotation of the second wheel are neither coaxial nor parallel to each other. For example, the axes of rotation of the wheels 14, 16 may be inclined relative to the axis A of the body.

Each wheel is provided as an annular member supported for rotation by the generally circular outer surface of the body portion 15,17. In other words, the body portions 15, 17 provide bearing housings that support the annular wheel members 14, 16 and allow it to rotate smoothly about its axis. Alternative configurations of wheels may be utilized without departing from the scope of the present invention. For example, one or both wheels may be mounted for rotation on a common or corresponding axis connected to the body.

It can be seen from the figures that the device 10 includes a handle 18 connected to the body 12 at the end of the support wheels 16 of the body 12 . A user-graspable handle 18 is connected to the main body 12 through an opening provided by the configuration of the annular wheel member 16 . This allows the user to move device 10 to a desired location. For example, the handle 18 allows the user to stand the device 10 upright on the end of the support wheels 14 of the device 10 such that the axis A of the body is substantially vertical. This configuration can also be used, for example, when a user uses the device for cleaning stairs or when storing the device.

As can be seen from the figure, the axis A through the body extends radially across the end of the body 12 , and said handle is smaller than the diameter of the outer surface of the wheel 16 . This ensures that the handle 18 does not soil the floor surface F when the device is moved along it.

While in the present example the handle 18 is fixed and not movable relative to the body 12, other embodiments are contemplated in which the handle is movable between a storage position and an operable position. For example the handle is movable towards and away from the central region C of the body 12 so that it can be moved between storage and operable positions. Additionally, means for retaining the handle in either or both of its stored/operable positions may also be provided. One benefit of such an embodiment would be that the handle, or a substantial portion thereof, is positioned within a recess in the end of the body, which thereby ensures that the device can stand substantially vertically on the end of the body.

As shown in FIGS. 1 and 2 , the apparatus 10 includes a tool 22 for engaging a floor surface and a conduit/hose 20 connecting the floor tool 22 to the body 12 . These components are well known in the art of such cleaners and will therefore not be described in more detail.

The conduit 20 comprises a flexible section connected to the main air inlet 70 of the device. The main inlet 70 is located substantially midway between the first wheel 14 and the second wheel 16 and extends vertically downward through the outer surface of the body and into the interior of the body 12 in normal use.

Referring specifically to Figure 15, the main air inlet is connected by a channel/inlet 72 to the inlet to the first cyclone separator means 110 so as to direct the incoming air (containing dirt particles etc.) in the direction of the arrow 71 until it enters the First cyclone separator unit 110 .

In the current embodiment, the first cyclone device 110 is a "throw-away" separator, the operation of which is well known in the art. The separator device 110 has a tangential inlet 72 into a generally cylindrical chamber 112 having an axis coaxial with the axis A. A dirt outlet 113 is located peripherally at one end of the chamber 112 (the end closest to the wheel 14), and the device 110 also includes an air outlet 114, also generally cylindrical, with a hole 115 through which air passes. 115 is passed in the direction of arrow 116 (coaxial with axis A) to a second cyclone arrangement 210 (discussed in detail below).

A chamber 112 is located within the chamber 100 for receiving dirt, and a dirt outlet 113 is in fluid communication with the chamber 100 such that dirt can pass therethrough and into the chamber 100 .

The dirt outlet 113 is configured to direct dirt into the chamber 100 in a direction 111 generally opposite to the direction of air entering the main air inlet 70 . Specifically, the dirt is directed into the primary air inlet 70 generally anti-parallel to the direction of air flow. By way of illustration, when the apparatus is in operation and the two wheels 14, 16 engage a generally horizontal floor surface F, dirt laden air passes substantially vertically downward through the main air inlet 70 and into the main body 12. . Dirt that has been separated from the air stream by the device 110 passes generally vertically upwards through the dirt outlet 113 and into the chamber 100 where it falls under gravity to the bottom of the chamber 100. lower part.

The configuration/location of the dirt outlet 113 is advantageous because it reduces the risk of the dirt outlet 113 being blocked due to dirt accumulating inside the chamber 100 . The device 10 includes means 80 for limiting the rotational movement of the body 12 about its axis A, as will be described hereinafter. Biasing means 80, although not required, also assists in the positioning of dirt outlet 113 to ensure that it does not rotate too far about axis A to reduce the likelihood of clogging.

As can be seen from the figure, the main body 12 also houses a second cyclone arrangement 210 comprising a plurality of smaller cyclones 211 positioned in an array about the axis A. As shown in FIG. Such devices are well known in the art. Each device 211 has a tangential inlet 212 in fluid communication with the outlet 114 of the first cyclonic separating device 110 , and a dirt outlet 213 . The dirt outlet 213 communicates with a space 214 inside the body, which provides a storage volume for dirt separated from the separator 211 . As can be seen in FIGS. 12 b and 15 , the space 214 communicates with an axially extending channel 215 terminating behind the wheel 14 .

Channel 215 terminates at inlet 216 , which is located adjacent to inlet 101 to chamber 100 . The two inlets 101 , 216 can be closed/opened by movement of the cover 19 . The cover 19 is pivotally connected to the main body 12 by a pivot connection 19a, and is movable between closed and open positions. Lid 19 includes a protruding portion 19b positioned substantially relative to said pivot connection 19a, which engages catch portion 50a to retain lid 19 in its closed position (described in more detail below). In its closed position, the cover blocks the inlets 101 , 216 , but in its open position it allows for emptying of the dirt contained in the chamber 100 and the channel 215 .

Each device 211 has an air outlet 217 communicating with the space supporting the pre-motor filter 90 . The air filter 90 is removable from the body 12 through a hole 91 in the outer surface of the body 12 (see FIG. 6 ). This ensures that the filter 90 can be cleaned and/or replaced when necessary.

Positioned within the main body 12 is a suction motor 140 having a rotor 141 drivably connected to the suction fan 150 . These components are positioned along the axis A of the main body 12 and, when powered, provide a suitable source of suction to draw air through the main air inlet 70, the first cyclone 110, the second cyclone 210 and the filter 90. A post-motor filter 160 is located adjacent to the rear end of the suction motor 140 (near the wheel 16 ), which is covered by a cover member 161 connected to the main body 12 . Air passes through this further filter 160 and holes in the cover part 161 to the atmosphere. Cover 161 is removable so that filter 160 can be cleaned and/or replaced when necessary.

Apparatus 10 also includes cable storage 170 for storing cables 68 for powering suction motor 140 . In the present example, the cable storage device 170 comprises an annular movable part 171 , which is rotatable about the axis A around the housing of the suction motor 140 . In the present example, the cable storage device 170 includes means for biasing the cable 68 to be drawn into the interior of the body 12 such that the cable is coiled around the ring member 171 .

The free end of the cable 68 is connected to a plug 69 which is at least partially received within a recess 67 in the body 12 when the cable 68 is fully stored. The positioning of the cable storage device 170 around the housing of the suction motor 140 ensures a very compact construction.

While in the present example the cable storage device 170 is rotatable about an axis coaxial with the elongate axis A of the body, it need not be. Said axis may be parallel to an axis offset from the axis A of rotation. Furthermore, while the axis of rotation of the cable storage device 170 is coaxial with the axes of rotation of the wheels 14, 16, it may be parallel to these axes or indeed inclined relative to these axes.

In alternative embodiments, the cable storage device need not be positioned around the housing of the motor. For example, it could be positioned between the motor 140 and the filter 160 , between the filter 90 and the suction fan 150 , or indeed anywhere else within the interior of the body 12 .

While the cable storage device 170 is rotatable about an axis generally parallel to the axis A of the body, it is rotatable about an axis extending transverse to the axis A. As shown in FIG. Furthermore, while the cable storage device 170 includes means for biasing the cable 68 to be drawn into the interior of the body 12, it is contemplated that it includes manually operable means for winding the cable 68 into the body 1. Example. For example there may be a handle accessible from the outside of the main body 12 which is moved by the user to rotate the ring member 171 to wind the cable into the interior of the main body 12 .

As mentioned before, the device 10 comprises means 80 for biasing the body into a first position relative to the surface F to be cleaned. In particular, the biasing means 80 is configured to bias the body 12 into a position wherein the primary air inlet 70 is substantially vertically inclined. More specifically, the biasing means 80 includes first and second ground engaging members in the form of a pair of wheels 81 , 82 supported for rotation about respective axes. Each wheel 81 , 82 is connected to the main body by a pair of pivotally movable members 84 , 85 , 87 , 88 . Members or arms 85, 88 include bifurcated end portions that receive wheels 81, 82, and opposite ends of arms 85, 88 are pivotally supported relative to the body. Members or arms 84 , 87 are pivotally connected at one end to wheels 81 , 82 by holes 86 , 89 , while the opposite end of each arm 84 , 87 is pivotally and slidably movable relative to body 12 . The arms 84, 87 are connected to each other by biasing means that bias the wheels 81, 82 towards each other.

The wheels 81 , 82 are thus each positioned on one side of the axis A of the body and are movable laterally in directions M1 , M2 perpendicular to the axis A of the body 12 in this particular example.

In this particular example, the biasing mechanism is a spring (not shown) extending transversely to the axis A of the body 12 between the arms 84 , 87 .

Although in the present example, the biasing device 80 is attached to the central region C of the body 12 , it may be positioned anywhere along the body 12 .

In FIG. 20 , the wheels 81 , 82 are shown in a respective first state, which corresponds to the main air inlet 70 being substantially vertically aligned. Figures 9 and 10 show the movement of the wheels 81, 82 when the body 12 is rotated about its axis A in either direction. FIG. 9 is an end cross-sectional view through the body 12 looking towards the wheel 16 where the body has been rotated about the axis A counterclockwise. It can be seen that the wheel 81 remains in contact with the surface F, but the arms 87, 88 pivot outwardly allowing the wheel 81 to move. It can also be seen that the wheels 82 are no longer engaged with the floor surface F. FIG.

In Fig. 10 the body has been rotated clockwise about axis A which has caused the wheel 82 to remain in contact with the floor surface F with the arms 84, 85 pivoting outwards but the wheel 81 no longer engaging the floor surface F.

The configuration shown in FIGS. 9 and 10 requires the user to apply rotational force to the body by pulling on the hose 20 . This will occur when the user pulls on the hose 20 to move the body 12 along the floor surface F, with the wheels 14, 16 rotating about their respective axes. Once the user reduces or removes the force applied to the body 12, the biasing means 80 is configured to cause the body to rotate about its axis A to a neutral position with the primary air inlet 70 positioned generally vertically. The restriction of the movement of the wheels 81, 82 ensures that the main body 12, and in particular the chamber 112 of the first cyclonic separation device 110, does not rotate too far around the axis A to ensure that the dirt leaves the chamber 112 freely through the outlet 113 and The dirt enters the chamber 100 as it is collected.

It can also be seen from the figure that the concave shape of the floor facing surface of the body provides space for providing a biasing means 80 which provides a compact structure of the device while maintaining sufficient volume in the interior of the body to accommodate the operation of the device 10 components.

Advantageously, the device 10 comprises a plurality of deflector members 41 , 42 , 43 , 44 connected to the main body 12 . The purpose of the deflector members 41 , 42 , 43 , 44 is to provide protection to the main body 12 and further assist the user in manipulating the device while cleaning. The deflector members 41, 42, 43, 44 advantageously assist the user in manipulating the device to move past fixed objects, such as door frames, chairs, tables (see Figure 21).

In this particular example, the device 10 comprises two pairs of deflector members 41 , 42 , 43 , 44 . However, it should be understood that embodiments are contemplated in which one or more deflector members are used.

More specifically, for the sake of clarity, it should be noted that the deflector members 41 , 42 are substantially mirror images of each other with respect to a plane extending perpendicularly through the axis A and the central region C. Furthermore, the deflector members 43 , 44 are mirror images of each other with respect to a plane extending through the axis A and through the main air inlet 70 . Therefore, only the deflector members 41 and 43 will be described in detail.

Said deflection member 41 is positioned between the main air inlet 70 and the wheel 14 and extends in a direction substantially parallel to the axis A therebetween. The deflection member 41 includes a pair of generally parallel upstanding walls 45 , 46 each including a portion extending beyond the upwardly facing outer surface of the wheel 14 . These sections are connected to each other by section 49 .

When viewed from the side (see Fig. 11), each wall 45, 46 comprises an outwardly facing surface or edge that tapers towards the axis A of the body. The edge 47 is located closest to the wheel 14 and tapers towards the axis A as it extends towards the wheel 14 . Connected to portion 47 by a bend is portion 48 which tapers towards axis A as it extends towards main air inlet 70 .

The space between the walls 45, 46 provides a space or recess suitable for positioning the user-operable controls 50, 56 of the device 10 therein. In the present example, a user-operable control 50 positioned within a recess or space of said deflection element 41 is pivotally movable in order to control the opening of the lid 19 . This can be seen in more detail in the cross-sectional view shown in FIG. 15 . The user-operable control 50 has a protruding/catch portion 50a which engages the portion 19b on the cover to hold the cover 19 in its closed position, and the member 50 is biased into this position by a suitable spring or the like. When a user depresses member 50, protrusion 50a pivots out of engagement with portion 19b to allow lid 19 to move to its open configuration (the lid may likewise be biased to its open configuration by a suitable spring or the like).

The space or recess provided within the deflection member 42 also supports a user-operable control 56 which is a power button for providing an electrical connection between the main power source and the suction motor 140 . It should be understood that other user-operable controls may be provided within spaces or recesses in the deflection member. Although no user-operable controls are provided in corresponding spaces in the deflector members 43, 44, they may be provided instead of or in addition to the members 50, 56 if desired.

The deflector member 43 is positioned adjacent the primary air inlet 70 and extends circumferentially around a portion of the main body 12 . Likewise, the deflector member 43 includes a pair of upstanding walls 57 , 58 extending generally parallel to each other and extending outwardly away from the axis A of the body 12 . Each wall includes a portion 60 extending outwardly away from the axis from near the main air inlet 70, wherein the portion has an edge that tapers outwardly away from the axis A as it extends away from the main air inlet 70. . The wall portion 60 is connected to another edge portion 59 extending downward toward the floor surface F by a bent portion. Edge portion 59 tapers toward axis A of the body as it extends downwardly away from edge portion 60 and circumferentially around body 12 . Likewise, spaces are provided between the wall portions in which user-operable controls or the like can be positioned.

Reference is now made to FIG. 21 , which illustrates one advantage of the deflector member according to the current embodiment. When users use the device 10, they typically pull on the hose 20 in order to move the main body along the floor surface F. As shown in FIG. It may often be the case that the user moves from one room to another, for example through a doorway, and can engage the device well with the frame ("object"). In prior art devices, it could also be the case that the body of the device would get stuck behind an object and the user would then have to manually move the device laterally to avoid the object. However, the deflector members, in particular the deflector members 41, 42, ensure that even when the body of the device engages such an object, the force P applied to the hose 20 causes the device 10 to move in the direction Q, since the deflector members provide A sliding surface which slides over the object providing said hindrance.

The positioning of the user-operable controls 50, 56 within the spaces or recesses of the deflector members 41, 42 ensures that they are somewhat protected against any damage due to collisions between the device and the fixed object.

Referring specifically to Figures 22 to 24, these illustrate a second embodiment of an apparatus utilizing aspects of the present invention.
