The The present invention relates to a surface cleaning device, such as. For Floors or Upholstered furniture, with an oblong rotatable brush arrangement and an electric motor for rotating the brush.
A current surface cleaning device generally uses absorbent. One of the disadvantages of such Suction means is that used to generate the suction power Fan are relatively inefficient, i. typically in use 10 to 20 percent are efficient, with the result that the device usually not easy to carry. This is especially the case if the device contains batteries for operating the motor. For this Reason it is not practical, batteries with sufficient power to integrate into a lightweight portable vacuum cleaner for effective cleaning to provide the required level of suction.
It is known, surface cleaning devices e.g. to provide sweeping, where an elongated Brush assembly, sometimes as a brush element is known, rotatable in a housing is stored, which is for driving in at least one forward direction accomplished is. The brush arrangement extends generally across the housing and is to touch the surface trained under her. The brush arrangement is arranged to by friction, which by driving the housing over the Ground is caused to be turned. The housing can with wheels Be provided with the surface touch. One of the disadvantages of such a design is that the friction drive not very effective.
It is also known to provide one or more auxiliary brush assemblies, extending from one or two front corners of the case Outside extend. The additional brush arrangement is intended for rotation about an axis inclined from the vertical and is provided with radial bristles. An additional brush arrangement of this This type is described in GB-A-1 547 286. The additional brush arrangement is freely rotatable and its rotation depends on the touch the floor or a baseboard of a room during the driving of the device over the Ground off. Such a rotating means is unreliable and has the consequence that dust and / or dirt particles on the ground towards the elongated one Rotary brush arrangement for Collecting are thrown through the device. Furthermore leads the Contact of the circular Auxiliary brush arrangement with the floor or a skirting board, that the bristles of the additional brush assembly, extending sideways from the case Outside extend an angle rotation effectively in the reverse direction. That means, that an additional brushing agent, coming from a front right corner of the case from the top and behind the Device seen to the outside extends, would be rotated clockwise and dust and / or dirt behind in the. Direction of the elongated rotary brush assembly would fling around. This is not very satisfactory.
GB-A-1 442 587 describes a surface cleaning device, the one body, an oblong, rotatable brush arrangement with bristles extending through an opening provided in the bottom of the body, and a chamber for receiving by rotation of the brush assembly Contaminated dirt includes.

The in the 1 and 2 Surface cleaning device shown comprises a body 1 which is suitably molded from plastic and effectively has three chambers.
In a back chamber 3 are an electric motor 5 and a rechargeable battery pack 7 accommodated. The battery pack 7 can be connected to a mains power supply (not shown) for recharging the battery pack. The battery pack may be connected to the mains either when the device is not in use or at appropriate times when the battery pack is discharged. A switching means (not shown) is provided to allow a user to turn the motor on and off 5 to permit as desired. As an alternative to egg In a rechargeable battery pack, the device could use disposable batteries or be powered by AC power.
In a front chamber 9 is an elongate rotatable brush assembly 11 accommodated. For convenience, a front wall of the front chamber is curved and extends around the periphery of the brush assembly 11 around. The bottom of the front chamber is on 13 open so that the bristles of the brush assembly can be contacted with a floor, carpet or the like over which the surface cleaning device is to be moved. The back of the front chamber is a backward sloping wall 15 , the dirt, such as dust, rubbish and the like, by the rotation of the brush assembly 11 drive up the wall and over the wall into an intermediate chamber 17 , which will be described in more detail below, lets happen. The wall 15 extends up to about the same height as the top of the brush assembly 11 and is angled at an angle of about 18 degrees to the rear (ie, away from the anterior chamber). The exact angle is not important, but the slope facilitates the passage of the dirt up and over the wall and at the same time facilitates the retention of the dirt in the intermediate chamber 17 , The brush assembly extends substantially over the entire width of the front chamber and is provided with two spirally arranged rows of bristles. The two rows are exactly opposite each other and each row is in the form of a pair of separate spirals which are rotated in opposite directions and meet substantially midway between the ends of the brush assembly.
The intermediate chamber 17 is between the wall 15 and a wall 21 positioned the electrical components 5 . 7 in the back chamber 3 includes, with the wall 21 protects the components in the rear chamber from the ingress of dirt. The intermediate chamber 17 Also has a bottom wall, a top wall and side walls that extend from the outside wall of the body 1 be formed. Dirt accumulates in the intermediate chamber 17 at. The intermediate chamber is provided with a removable closure to facilitate the removal of dirt. For example, one of the walls, such as a side wall, the top wall, or the bottom wall, may be removed to allow debris to be discharged from the intermediate chamber, with the removed wall being replaced when the chamber has been emptied. Ideally, the side wall 23 be removed for emptying purposes. The wall 15 gives the advantage that dirt does not escape easily from the intermediate chamber 17 can escape and that the dirt escapes even from the intermediate chamber when the body is tilted so that the front chamber is below the intermediate chamber.
The brush arrangement 11 is from the engine 5 by means of toothed rollers 25 . 27 , which are attached to the engine or to the brush, and by means of a toothed belt 29 For example, from an elastic polymerization product, which runs around the two rollers rotated. The timing belt 29 is in a tunnel 31 included where he passes through the intermediate chamber 17 passes through to the ingress of dirt into the rear chamber 3 to prevent. The tunnel 31 can at any convenient point through the intermediate chamber 17 be laid. Especially in the case that the side wall 23 For drainage purposes, the tunnel can be removed from the side wall 23 far side of the intermediate chamber 17 be arranged.
On the body 1 is in the area of the rear chamber 3 a grip handle 33 attached, the body with a recess 35 is formed under the handle handle so that the handle handle can be grasped, while a flat design for the surface cleaning device is preserved. The handle 33 can be in two parts with a first part 37 that on the body 1 is attached, and a second part 39 taken from the first part and by a longer stem part 41 can be replaced, as in 3 will be shown. The longer stem part 41 is with a swivel mechanism 43 provided so that the stem part 41 around the axis of it relative to the body 1 can rotate, and with a turning means 45 so that the stem part can rotate about an axis transverse to the axial direction of the stem part so that the surface cleaning device can be steered by the user. As an alternative to replaceable handle stems, the stem part 41 removable with the stem part 33 be engaged. In such a case, the stem part 33 arranged so that the pivoting means 43 only in certain positions of the stem part 33 works so that the movement can be locked when the stem part 33 is used alone.
As in particular 3 As can be seen, extend the bristles of the brush assembly 11 from the opening in the front chamber 9 outward. To remove stubborn dirt and / or to refresh a carpet, the front region of the front chamber is movable (including removable) to expose the bristles in this region more. In this way, the front part of the device can be inclined relative to the surface to be cleaned, thereby increasing the contact between the bristles and a surface to be cleaned, and in some surfaces increasing the penetration and cleaning depth of the bristles on the surface.
Although not shown, an additional rotary brush on the side of the brush assembly 11 into which the role 27 and the belt 29 are incorporated, are provided. Such an auxiliary brush is described, for example, in GB-A-1 547 286. Such an additional brush can dirt in the path of the brush assembly 11 return, otherwise because of the lack of bristles in the region of the role 27 would not be recorded. The auxiliary brush may be driven by any suitable means, such as a gear from the brush assembly 11 or by friction with the surface to be turned off, and is on the body 1 hung up and extends outward beyond him. The auxiliary brush may comprise a cylindrical body that can rotate about an axis that is inclined about 10 degrees to the vertical, so that it extends outward over the body 1 extends beyond. Bristles project radially outwardly from the periphery of the cylindrical body, but need not be perpendicular to the axis of rotation and may preferably be at an angle of about 80 degrees to the axis of rotation to form a cone whose cross-section increases with distance from the body 1 gets bigger.
The front part of the anterior chamber 9 although not shown, can be removed to expose the bristles on the front of the device. This effectively increases the opening in the front chamber, which would severely affect the effectiveness of a vacuum cleaner, but can be effectively used in the present invention to assist in sweeping steps, cleaning upholstery and carpeting in vehicles, and such operations a larger exposed bristle area may be helpful to help. As an alternative to removing the front part of the chamber 9 For example, the front portion may be movable relative to the remainder of the chamber, for example pivotally or slidably, to expose the bristles.
The rear chamber 3 Although not shown, may be provided with wheels that are non-positive to the ground to aid in the mobility of the surface cleaning device. For example, the non-ground wheels may be located outside in the side regions of the rear chamber 3 be formed or they may be provided in recesses, at least partially under the rear chamber 3 are formed.
The Although illustrated embodiments of the present invention are primarily for provided the household use, the surface cleaning device, if desired, but also used outdoors or in workshops. Perhaps but is preferably a more robust construction, specifically for such Use executed is provided.
When using the surface cleaning device according to the invention, as in 1 and 2 As shown, the device is placed on a surface to be swept, such as a carpet, and the switch is actuated to turn on the motor and thus rotate the brush assembly to sweep dirt off the surface and then sweep the dirt against the sloped wall 15 up and over them and into the intermediate chamber 17 to drive where it is temporarily stored. while the surface cleaning device with rotating brush assembly 11 is moved across the surface, any further dirt is swept the same off the surface and on the wall 15 up and over them and into the intermediate chamber 17 driven. The surface cleaning device is extremely portable and can be used wherever it should be needed. For example, it can be used for sweeping stairs without the need for electrical cables or suction hoses. The shape of the device with the rounded shape of the rear chamber, as illustrated, facilitates the movement of the device over stairs, but ground-engaging wheels can be provided to further facilitate such sweeping operations.
If the intermediate chamber 17 is to be emptied, a wall of the chamber is removed as described above and the dirt can be easily ejected. The removable wall is then replaced. Alternatively, the intermediate chamber may be in the form of a shell which can be removed and emptied to eject dirt.
For example, if the surface cleaning device is not in use, it may be stowed in a cabinet or the like or connected to a mains power supply to the battery 7 recharge.
The surface cleaning device of the present invention thus has an electrically powered brush assembly. The brush assembly is not affected by frictional forces between the surface cleaning device and the surface. which it is moved, powered. The efficiency of the device therefore does not depend on the type of frictional contact. Furthermore, the device for drawing the dirt into a storage chamber does not rely on suction. The effectiveness of the device therefore does not depend on the effectiveness of suction means and the considerable energy absorption of the suction means from the rechargeable battery is avoided. Placing the motor at the back of the device eliminates the need for greater height should the engine overshoot to collect dust and the like, and also provides effective full-width cleaning, which would not be possible if the motor were positioned in the dirt collection chamber. In such a position, dirt likes to accumulate around the engine causing blockages. The present invention solves this problem by laying the brush assembly drive means at least partially through the dirt chamber.
The device 102 for cleaning a surface 104 by sweeping, being on the 4 . 5 and 6 Reference is made to a housing 106 suitably molded plastic material and effective with three chambers. In a back chamber 108 are an electric motor 110 and a rechargeable battery pack 112 accommodated. The battery pack 112 can be connected to a mains power supply (not shown) to recharge the battery pack. The battery pack may be connected to the mains either when the device is not in use or at appropriate times when the battery pack is discharged. A switching means 113 is provided to a user to turn on and off the engine 110 to permit as desired. As an alternative to a rechargeable battery pack, the device could use disposable batteries or be mains powered.
In a front chamber 114 is a transversely disposed elongate rotatable brush assembly 116 with bristles 118 accommodated. Such an elongate rotatable brush assembly 116 is sometimes known as brush element. The bottom of the front chamber 114 is on 120 open so the bristles 118 the elongated brush assembly 116 can touch a floor, carpet or the like over which the device is to be driven. The back of the front chamber is a backward sloping wall 122 , the dirt, such as dust, rubbish and the like, by the rotation of the brush assembly 116 drifting up the wall and over the wall into an intermediate chamber 124 lets happen. The front of the front chamber is provided with a cover (not shown) which is movable. Himself in the intermediate chamber 124 accumulating dirt can by opening a cover 126 be removed. The wall 122 extends upwardly to about the same height as the top of the elongated brush assembly 116 and may be angled at an angle, such as an angle of about 18 degrees, to the rear (ie, away from the anterior chamber). The exact angle is not important, but the slope facilitates the passage of dirt on the wall 122 high and above them while facilitating the retention of debris in the intermediate chamber 124 ,
The elongated brush arrangement 116 is from the engine 110 by means of toothed rollers 128 . 130 , which are attached to the motor or on the brush assembly, and by means of a toothed belt 131 For example, from an elastic polymerization product, which runs around the two rollers rotated. The timing belt 131 is where he passes through the intermediate chamber 124 through or along alongside it, in a tunnel 132 trapped to prevent dirt from entering the rear chamber 108 to prevent.
An additional brush agent 134 is provided, that is, from above and behind the device 102 viewed from the housing 106 on the right side of the elongate rotatable brush assembly 116 extends to the outside. The additional brush agent 134 has a substantially circular shape and is about an axis 136 rotatably mounted, which may be inclined vertically or from the vertical, such as at an angle of about 10 degrees to the vertical. The additional brush agent 134 has a body 138 , with radial bristles 140 is provided at an acute angle to the axis of rotation 136 are inclined to effectively form a conical arrangement whose cross-section increases with distance from the body 138 gets bigger.
The additional brush agent 134 is via a gear wheel 142 at the end of the elongated brush assembly 116 that with another gear 144 on the body 138 of the additional brush agent 134 is engaged by the rotating elongate brush assembly 116 driven in rotation. The additional brush agent 134 will turn into a with arrow 146 designated direction in the counterclockwise direction, from above and behind the device 102 considered, driven. During such rotation of the auxiliary brush means 134 A peripheral region thereof rotates from a laterally directed position 148 ( 6 ) outside the case 106 through a forward position 152 to an opposite laterally directed position 150 coming from the case 106 is covered.
The device 102 is with a handle handle 154 provided by means of which they at least in a forward direction 156 can be driven forward. They are wheels 158 and 160 provided to manually drive the device over the surface to be turned off 104 such as a floor, stairs or upholstery, to enable or support. The handle 154 could be longer as needed or have a different shape or shape.
The rotating auxiliary brushing agent 134 is not in contact with the surface for its rotation che 104 dependent and therefore gives a more efficient sweeping of edge regions of the surface 104 regardless of the type of surface 104 , Furthermore, the direction of rotation ensures 146 of the additional brush agent 134 that dirt from the auxiliary brush assembly 134 forcibly into position in front of the rotating elongated rotary brush assembly 116 swept where it is to be picked up by the elongated brush assembly 116 ready.
If desired, the same may be substituted for or in addition to the intended auxiliary brushing agent 134 that extends from the right side of the case 106 extending outwardly, a similar auxiliary brush means (not shown) may be provided extending from the left side of the housing 106 extends outwardly and from the opposite end of the elongated brush assembly 116 is driven. Such additional or alternative auxiliary brush means differs from the auxiliary brush means 134 only by turning it clockwise instead of counterclockwise, from above and behind the device 102 considered.
Instead of that the device 102 with a battery or mains powered electric motor 110 for driving the elongated brush assembly 116 and thus the additional brushing agent 134 can be provided, a known form of friction drive means (not shown), resulting from the driving of the device 102 along the surface 104 results, used to the rotation of the elongated brush assembly 116 and thus the rotation of the auxiliary brush means 134 to effect.
In 7 an alternative embodiment of a device according to the present invention is shown. Such an alternative embodiment comprises an upright vacuum cleaner device 102A with a housing 106A with wheels 158A and 160A , a rotating elongated brush assembly 116A and an auxiliary brushing agent 134A , The device 102A is essentially similar to the device 102 of the 4 . 5 and 6 built with the main exception that instead of the dirt collection chamber 124 from 5 a dirt collector 124A , which can be a bag, among other things, between a handle handle 154A and the housing 106A is provided and about a well-known form of suction assembly (not shown) with the housing 106A connected is.
