Description

Device for cleaning floor
The application is a divisional application with the application date of 2014, 2, 7, the application number of 201480074923.X and the application name of the invention of the device for cleaning the floor.
Technical Field
The present invention relates to a device for cleaning a floor and/or a floor tool for use in the device. In particular, the present invention relates to a device which utilizes a suction source to draw in dirt and/or debris from the floor being cleaned, the dirt and/or debris being stored in a dust chamber or bag which can be emptied by a user. Such devices are commonly referred to as "vacuum cleaners".
More particularly, the present invention relates to an apparatus having an upright member pivotally connected to a base assembly supported on wheels. The user can grasp the handle of the upright member to push and pull the base assembly across the floor to clean the floor as desired. The base assembly includes a passage terminating in an opening to the ground and to which a suction source applies suction to cause air and dirt entrained within the air to move towards the dirt collection chamber. The base assembly includes a cleaning member driven by a motor to assist in cleaning a carpet or underlay. The cleaning member is generally cylindrical and has bristles extending radially outward from its long axis. The cleaning members are supported for rotation about their long axes, and the distal end portions of the bristles extend through the ground-facing opening of the device during use. The motor is drivingly connected to the cleaning member by a belt or the like, causing the cleaning member to rotate.
Background
When the device is used to clean a floor surface covered by a carpet, it is desirable that the cleaning member is positioned close to the carpet so that the bristles are in contact with the carpet. Dirt is loosened by the cleaning member and entrained in the suction airflow. When the device is used to clean a hard floor, such as a composite or tile floor, it is undesirable for the bristles of the cleaning member to contact the floor, as this can result in a reduced finish on the floor. For example, the bristles may scratch or remove any floor coating, such as a polishing layer. To overcome this problem, it is known to provide means for lifting the part of the base assembly supporting the cleaning member from the floor surface, thereby releasing the cleaning member from contact with the floor surface. Dirt on the floor is still entrained in the suction airflow through the opening towards the floor. However, one disadvantage of this arrangement is that the opening to the ground is relatively far from the ground, meaning that the amount of air drawn in close proximity to or on the floor is reduced. Thus, the cleaning process is less effective.

Detailed Description
Referring to the drawings, there is shown one embodiment of an apparatus 10, wherein the apparatus 10 embodies various aspects of the present invention. The device 10 includes an upright member 12, the upright member 12 including a user-graspable handle and base assembly 14. Base assembly 14 includes first base member 16 and second base member 18 connected to one another. The first base member 16 is located behind the second base member 18. First base member 16 is connected to upright member 12. The second base part 18 includes a cleaning member 20. In one aspect of the present invention, apparatus 10 includes a device 22 for moving first base member 16 and second base member relative to one another.
The upright member 12 is pivotally connected to the base assembly 14 away from the front edge of the base assembly 14. The upright member 12 contains the operative components of the device 10, such as a suction source in the form of a suction motor and fan that provides suction to the base assembly 14, and a dirt collection chamber that receives any dirt entrained in the airflow drawn through the base assembly 14. The upright member 12 includes a dirt separator in the form of a cyclonic separator which separates dirt entrained in the suction airstream from the base assembly 14. These components are not shown in the drawings, but are well known in the art and therefore will not be discussed further herein. Although this embodiment includes a cyclonic separator, other embodiments of the invention may not include the separator, but rather use a dust bag to collect dirt from the airflow.
First base member 16 includes a first side 24 and a second side 26, with first side 24 and second side 26 being spaced apart from one another to define a portion of an interior space 28. Within the interior space 28, a lower portion of the upright member 12 is positioned proximate a rear portion of the base assembly 14. The lower portion of upright member 12 is pivotally connected to respective side portions 24, 26. The side portions 24, 26 support respective wheels 30, 32 that allow the base assembly 14 to roll over a ground surface. One of the side portions 24 includes an airflow passage 34, one end of the airflow passage 34 including a connection for the hose 25 and the other end being fluidly connected to the second base member 18 (described in more detail below). Hose 25 is connected at one end to airflow passage 34 and at the other end to a passage in upright member 12 which is in fluid communication with a suction source (not shown). This arrangement allows suction to flow from the first base member 16, through the second base member 18 and to the dust chamber.
The second base part 18 has a generally elongate main portion 36, the main portion 36 extending transversely across the device, with a curved semi-circular (internal cross-sectional) outer surface. The second base part 18 has two portions 38, 40 spaced from each other and extending from the main portion 36 to the first base portion 16. The portions 38, 40 are connected to respective side portions 24, 26 of the first base member 16 (as will be described below).
The second base member 18 includes a first passage 42 having a corresponding inlet 44 and a second passage 46 having a corresponding inlet 48. A portion of the first passage 42 bypasses the outer surface of the main portion 36 and a portion of the second passage 46 is formed by the interior space defined by the main portion 36. Passages 42, 46 extend through one of the side portions 38 and communicate with a valve 49 having a valve member 50. Valve 49 is also in fluid communication with airflow passage 34 of first base member 16. A suction source provides suction to the first and second passages 42, 46, and movement of the valve member 50 controls the flow of suction provided to the passages 42, 46.
Inlet 48 of second passage 46 is located rearward of inlet 44 of first passage 42 and between inlet 44 of first passage 42 and the connection of first base member 16 to upright member 12. The inlets 44, 48 are rectangular in shape and extend longitudinally along the main portion 36 of the second base member 18. The longitudinal direction is defined as the direction perpendicular to the forward or rearward direction in which the user moves the base assembly 14 during cleaning. The width direction is defined as the direction parallel to the forward or rearward direction in which the user moves the base assembly 14 during cleaning. The inlets 44, 48 allow airflow therethrough. The inlet of the first passage 42 is relatively narrow compared to the inlet of the second passage 46. The inlets 44, 48 each include a respective rib that extends widthwise across the inlets 44, 48, thereby dividing the inlets 44, 48 into a plurality of respective apertures. The width of each rib of the inlet 44 is 4mm and the width of each rib of the inlet 48 is 4 mm. In other embodiments, no ribs may be provided, or more or fewer ribs may be provided. The second base member 18 includes a ground engaging portion 52, with the ground engaging portion 52 being located between the inlet 44 of the first passage 42 and the inlet 48 of the second passage 46.
The cleaning member 20 is located in the second channel 46 and its respective inlet 48. The cleaning member 20 is generally cylindrical and has bristles extending radially outward from its long axis. The cleaning members 20 are supported for rotation about their long axes with the distal end portions of the bristles extending through the entrance of the second channel 48. A motor (not shown) for driving the cleaning member 20 is located in the first base member 16 and is drivingly connected to the cleaning member 20 by a belt 54.
The junction between the first and second base members 16, 18 includes an elongated, generally cylindrical bar 56, with the bar 56 extending along the width of the interior space 28. The rods 56 pass through corresponding apertures provided in the end portions of the side portions 24, 26, 38, 40 to pivotally connect the components 16, 18 together. The valve member 50 is connected to the rod 56 such that rotation of the rod 56 causes pivotal movement of the valve member 50.
The apparatus 22 comprises a substantially wedge-shaped cam member 58, which cam member 58 is connected to the rod 56 (which is formed as a single component part), and a cam follower 60, which cam follower 60 is pivotally connected to the first base part 16. The cam members 58 taper towards the respective free ends. A cam member 58 extends radially away from the rod 56. The cam followers 60 are generally rectangular members that extend widthwise across a portion of the interior space 28 and are supported by a pair of corresponding ground engaging wheels 61. The upwardly facing surface of the cam follower 60 cooperates with the cam member 58. Rotation of the lever 56 causes movement of the cam follower 60, which in turn causes relative movement between the first and second base members 16, 18 (described below).
The apparatus includes a user operable member 62, the member 62 being pivotally supported on one side of the base assembly 14 and located on one side of the base assembly 14 for actuating the device 22. The user operable member 62 is disc-shaped and is connected to one end of the lever 56. The pivot axis of the user operable member 62 is coaxial with the pivotal connection of the first and second base parts 16, 18. The pivotal connection of first base member 16 and second base member 18 is parallel to the pivotal connection of first base member 16 and upright member 12. The user rotates the user operable member 62 by his or her hand to operate it.
Although the user connects the device 10 to a power source via a cable (not shown), the device may be battery powered. The user must place the device 10 in a first state more suitable for hard floor cleaning or a second state more suitable for carpet cleaning. As described below, the components of device 10, such as first base member 16, second base member 18, valve 49 and valve member 50, may be movable between first and second states corresponding to first and second states of device 10.
Assuming that the user brings the apparatus 10 into its first state to clean hard floors, the user holds the user-operable member 62 by hand, rotates it in a first forward direction, and actuates the device 22 to cause corresponding rotation of the lever 56. As the cam member 58 rotates, the distal end of the cam member 58 pushes against and slides over the upward facing surface of the cam follower 60. The upward facing surface of the cam follower 60 has a slight slope that makes it easier for the cam member 58 to slide past the cam follower 60 until the cam member 58 eventually reaches a substantially vertical position. In this manner, the connection between the first and second base members 16, 18 moves generally upwardly (i.e., away from the ground) to its respective first condition.
The first and second base members 16, 18 are pivotally connected such that the pivotal connection therebetween causes the second base member 18 to pivot downwardly about the connection under the force of gravity. The second base member 18 also pivots about the ground engaging portion 52, but the ground engaging portion 52 also translates rearward toward the first base member 16. It will be seen that the front edge of second base member 18, distal from its connection with first base member 16, pivots towards the ground while the rear portion of second base member 18, distal from the front edge, pivots away from the ground. When the device 22 causes the second base part 18 to move to its respective first state, the cleaning member 20 is in a raised position in which the cleaning member 20 is out of contact with the floor. When the second base member 18 is in its first condition, the leading edge of the second base member 18 is positioned closer to the ground than when the second base member 18 is in its second condition. It can also be seen that when the second base member 18 is in its first condition, the entrance to the first passage 44 is located closer to the ground than when the second base member 18 is in its second condition.
Since the valve member 50 is connected to the stem 56, rotation of the stem 56 also causes the valve member 50 to move to its first state accordingly. When the valve member 50 is in its first state, the valve member 50 is positioned within the second passage 46 to block the second passage 46 while keeping the first passage 42 open. Thus, the suction source provides suction flow only in the first passage 42 because the position of the valve member 50 blocks suction flow in the second passage 46. The user may then begin cleaning the hard floor.
Assuming the user brings the apparatus into its second state to clean a carpeted floor surface, the user grips the user operable member 62 by hand, rotates it in the second rearward direction, and actuates the device 22 to cause corresponding rotation of the lever 56. As the cam member 58 rotates, the tip of the cam member 58 moves away from and out of contact with the upward facing surface of the cam follower 60. The cam member 58 eventually reaches a substantially horizontal position. In this manner, the connection between the first and second base members 16, 18 moves generally downward (i.e., closer to the ground) to its respective second condition.
The lowering of the pivotal connection causes the second base member 18 to pivot about the ground engaging portion 52 such that a rear portion of the second base member 18, distal from the front edge, pivots toward the ground and the front edge of the second base member 18 pivots away from the ground. When the device 22 causes the second base part 18 to move to its respective second state, the cleaning member 20 is in a lowered position in which the cleaning member 20 is in contact with the floor. It can be seen that when the second base member 18 is in its second condition, the leading edge of the second base member 18 is located further from the ground than when the second base member 18 is in its first condition. When the second base part 18 is in its second state, the cleaning member 20 is positioned closer to the floor than when the second base part 18 is in its first state. Since the cleaning member 20 can agitate the carpet during cleaning, the device is in a mode suitable for carpet cleaning.
Actuation of the device 22 causes the valve member 50 to move to its second state in which the valve member 50 is located in the first passage 42. When the valve member 50 is moved from its first state to its second state, the suction flow is diverted from the first passage 42 to the second passage 46. In other words, as the second base member 18 is moved to its second state by the apparatus 22, the valve 49 reduces the flow of suction in the first passage 42 and increases the flow of suction in the second passage 46. When the valve member 50 is moved to its second state, the suction source will only provide a suction flow in the second passage 46 due to the position of the valve member 50. The user may then begin cleaning the carpet.
The provision of the second base part moving to its first state is advantageous as it means that the first passage associated with hard floor cleaning is closer to the floor surface without the cleaning member being in contact with the floor surface. Thus, even if the portion of the second base part containing the cleaning member is raised, the amount of suction airflow provided through the inlet of the first passage close to or on the floor surface is increased. Thus, the cleaning process of hard floors is more efficient. Likewise, the movement of the second base member to its second condition is advantageous in that it brings the path associated with carpet cleaning closer to the floor to increase the flow of suction therethrough to make carpet cleaning more effective.
It is also advantageous that the valve operation is linked to the movement of the second base part such that the suction flow is diverted to the first or second channel upon a cleaning operation. This is because it means that substantially all of the suction provided by the suction source will be directed to the passage associated with the respective cleaning operation. Thus, the amount of suction airflow is maximized to more effectively pick up dirt/debris.
In this embodiment, the device 22, the user operable member 62 and the valve member 50 are all connected to the stem 56. That is, they are mechanically coupled to or form a part of the connection between the first and second base members 16, 18. Thus, operation of the user operable member 62 causes simultaneous actuation of the device 22 and the valve member 50. However, in other embodiments, one or more of these components may be formed independently of the connection between the base members. In these embodiments, other mechanical devices may be provided to actuate or move the assembly when the user operates the user operable member 62. In other embodiments, one or more of the components may be electronically activated and controlled by user-operable electronic circuitry.
Also in the present embodiment, the suction flows in the first and second passages 42, 46 are simultaneously changed in accordance with the movement of the first and second base members. In other embodiments, the suction flow may be changed, i.e., increased or decreased, before or after the first and second base members 16, 18 are moved to their first or second configurations.
This embodiment uses the valve member 50 to block one of the passages 42, 46 so that there is no or substantially no suction flow in that passage. In other embodiments, other variations in suction may occur. For example, in other embodiments, the suction force is only reduced by the valve member 50, as opposed to blocking substantially all of the suction flow in the channel. For example, in one embodiment, the device is arranged such that when the valve member is in its first state, the suction flow in the first passage is greater than when the valve member is in its second state. In other embodiments, the apparatus is arranged such that when the valve member is in its second condition, the suction flow in the second passage is greater than when the valve member is in its first condition, and/or when the valve member is in its first condition, the suction flow in the first passage is greater than the suction flow in the second passage.
It should be understood that the terms "first state" and "second state" do not necessarily correspond to a hard floor mode of operation or a carpeted floor mode of operation of the apparatus 10. One or more aspects of the present invention may be applied to an apparatus that need not be configured to be capable of switching between a hard floor mode of operation or a carpeted floor mode of operation. The terms "first state" and "second state" are reference points by which the functional operation of the device between intermediate or final operating stages for different components is defined.
In some embodiments, the suction flow may be kept constant in one channel and increased or decreased in the other channel when the first and/or second base part is moved between the first and second conditions. In alternative embodiments, the apparatus may be arranged such that when the suction provided to the first channel increases or decreases, the suction provided to the second channel decreases or increases conversely.
The suction provided to the first channel and/or the second channel may be increased or decreased. In alternative embodiments, the device may not include a valve. For example, the respective suction motor may provide suction to the channel, and the amount of suction provided by the suction motor may increase or decrease as the base member moves between its first and second states.
In the present embodiment, the cleaning member 20 is in the form of a motor-driven agitator. In other embodiments, other types of cleaning members may be used, such as agitators that are not driven by a motor, such as turbine driven agitators, or static brushes.
One aspect of the invention is that the base assembly need not be made of two parts that are connected together, or necessarily include a cleaning member. According to this aspect of the invention, the base assembly includes a base member including a first passage having a respective inlet and a second passage having a respective inlet. The suction provided to the first and second channels varies as the base component is moved between its first and second states by the apparatus. The apparatus is arranged such that movement of the base member causes a change in the suction provided to the first and second channels. In other embodiments, the change in suction force may occur before or after the base member is moved.
The inlet of the first passage is located closer to the ground when the base member is in its first state than when the base member is in its second state. The inlet of the second passage is located closer to the ground when the base part is in its second state than when the base part is in its first state.
In other embodiments, the suction provided to one, but not both, of the channels is varied.
One aspect of the present invention relates to the provision of the respective inlets 44, 48. According to this aspect of the invention, the first inlet 44 and the second inlet 48 lie in respective planes a, B. The planes a, B intersect around or near the ground engaging portion 52 between the respective inlets 44, 48.
Referring to the drawings, and in particular to FIG. 9, it will be seen that the respective planes A of the first passages 44 are inclined at an angle β relative to the respective planes B of the second inlets 48, the first inlets 44 being spaced from the second inlets 48 in a generally perpendicular direction.
Referring to FIG. 10, the second base member 18 is pivotally movable between its first condition (shown in phantom) and its second condition (shown in solid) at an angle θ the device 10 is configured such that the angles β and θ are equal, or substantially equal, in this embodiment 6.
It is noted that the suction/cleaning of the device 10 in the first state is surprisingly improved when the angle of β and/or θ is 6 ° or 7 °, however, an angle of about 4 ° to 8 ° is also advantageous for cleaning.
This arrangement is advantageous because it means that the inlet of the first channel 44 lies in a plane parallel or substantially parallel to the ground when the second base part 18 is in its first state, and the inlet of the second channel 48 lies in a plane parallel or substantially parallel to the ground when the second base part 18 is in its second state. This reduces the loss of suction flow.
It will be seen that the second inlet 48 lies in a plane that is generally inclined relative to the ground when the second base member 18 is in its first condition, and the first inlet 44 lies in a plane that is generally inclined relative to the ground when the second base member 18 is in its second condition.
In other embodiments, the respective planes are spaced apart from each other and/or from each other in a generally vertical direction away from the ground. In the illustrated embodiment, the respective planes intersect around the ground engaging portion 52, but in alternative embodiments, the planes may not intersect around the ground engaging portion 52 of the base assembly 14.
As shown in fig. 11, the first inlet 44 has a length 64 and a width 66, and the second inlet 48 has a length 68 and a width 70. One aspect of the present invention relates to how the dimensions of the first inlet and the second inlet are selected to produce an unexpected improvement in cleaning effectiveness and suction characteristics.
The first inlet 44 has a width of 17mm and a length of 338 mm.
Other advantageous embodiments are also contemplated in which the width 66 of the first inlet 44 is within the following range: 12mm to 22mm, or more preferably 15mm to 19 mm; the length 64 of the first inlet 44 lies in the following range: 280mm to 350mm or, more preferably, 300mm to 340 mm.
The second inlet 48 has a width of 41mm and a length of 320 mm.
Other advantageous embodiments are also contemplated in which the width 70 of the second inlet 48 is within the following range: 30mm to 50mm, more preferably 35mm to 45mm, still more preferably 40mm to 45 mm; the length 68 lies in the following range: 280mm to 350mm, more preferably 290mm to 340mm, more preferably 310mm to 330mm, more preferably 290mm to 300 mm. Other advantageous specific values for length 68 are 293mm and 294 mm.
It will be appreciated that one or more features of the base assembly in one or more of the embodiments described herein with respect to the upright cleaner may be incorporated as part of the floor tool of the cleaner (e.g., a floor tool connected to a bucket or canister cleaner). Fig. 12a and 12b show such a ground tool 101 embodying different aspects of the present invention.

One aspect of the invention relates to a floor tool 101 comprising a base assembly 114, the base assembly 114 comprising a first base part 116 and a second base part 118 located in front of the first base part 116. The base assembly 114 includes a first channel 142 having a first inlet 144 and a second channel 146 having a second inlet 148. The base assembly 114 includes a cleaning member 120 and a device 122 for moving the first and second base members 116, 118 relative to one another. The cleaning members 120 are located in the second channel 146 and their respective inlets 148.
The first base part 116 includes a rearwardly extending connecting member which connects with a suction tube (not shown) of the cleaner to provide fluid communication between a suction source of the cleaner and the first and second channels 142, 146. The first base member 116 includes a turbine 170, the turbine 170 having a rotor drivingly connected to the cleaning member by a belt 154. The turbine 170 is positioned within the suction flow path and rotates during use to correspondingly drive the cleaning member 120 during use in a known manner. A motor may be used instead of the turbine 170 or in addition to the turbine 170.
The general arrangement and operation of the floor tool and its components is similar to that described in the previous embodiments and will not be described in detail here. It will be appreciated that aspects of the invention relating to the apparatus 10 may be applied equally to the floor tool 101.
