Description
A Blower-Vacuum Device
The present invention relates to a blower-vacuum device, in particular of the type which has a blower attachment which enables the device to work in a blowing mode to blow debris into piles and a vacuum attachment which enables the device to work in a vacuum mode to suck up debris. Such devices are commonly used in gardens to blow debris, such as leaves and grass cuttings into piles and to then suck the debris up into a collecting bag for disposal.
Known devices, for example that disclosed in US Patent No.
4,325,163, have a motor which is located in a housing and which drives an impeller located in a volute. The volute has an air inlet located in front of the impeller and an air outlet located radially of the impeller.
When the device is used as a blower, a grill is attached over the air inlet of the volute and a blower duct in the form of a tube is attached over the air outlet. When the motor is switched on the impeller rotates and draws an airstream into the air inlet and expells it radially from the air outlet. The user holds the device with the blower duct pointing predominantly downwards and air exits the bottom of the blower duct to blow debris on the ground into piles.
When the device is used as a vacuum the grill and the blower duct are detached from the volute. A suction duct is placed over the air inlet and a collecting bag is connected over the outlet from the volute. When the motor is switched on the impeller rotates and draws an airstream and entrained debris up the suction duct and axially into the volute and expells air and entrained debris radially out of the volute and into the collecting bag. The user holds the device so that the suction duct points predominantly downwards to suck up debris from the ground.
Alternatively, known devices, such as that disclosed in European
Patent No. 657 587 have a motor which is located in a housing and which drives an impeller located in a volute. The volute has an air inlet located in front of the impeller and an air outlet located radially of the impeller. A blower duct in the form of a tube is extends from the air outlet. When the motor is switched on the impeller rotates and draws an airstream into the air inlet and expells it radially from the air outlet.
When the device is used as a blower the air is exhausted from the end of the blower duct distant from the impeller. The user holds the device with the blower duct pointing predominantly downwards to blow debris on the ground from one place to another.
When the device is used as a vacuum the air expelled from air outlet is directed along the blower duct and into a suction duct. The air expelled into the suction duct generates an entrained airflow in the suction duct which is used to suck debris up the suction duct and carry it to a collection bag.
A problem with known blower-vacuum devices is that their weight is not insignificant, especially in vacuum mode when the collection bag is becoming full. Thus, it can be quite tiring to the user to operate known blower-vacuums over extended periods. This problem is addressed in some known blower-vacuums by providing a shoulder strap with which a user can support the blower-vacuum.
However, the user still has to support the entire weight of the blower-vacuum and collection bag.
Additionally, in some application, such as vacuuming up grass clippings, there is an optimum distance between the end of the suction duct into which debris is sucked and the ground, at which the best vacuuming results can be achieved. It is difficult for a user of known blower-vacuums to maintain the device at this optimum distance.
The present invention intends to overcome the above detailed disadvantages and so provides an improved blower vacuum device.
According to the present invention there is provided a blower vacuum device comprising;
a motor in a housing,
an impeller which is driveable by the motor,
a volute within which the impeller is located having an air inlet and an air outlet,
a blower duct out of which an airstream is expelled when the blower vacuum is used in blower mode, and
a suction duct into one end of which debris is sucked when the blower vacuum is used in vacuum mode, characterised in that the blower vacuum additionally comprises at least one supporting wheel releasably attachable to said one end of the suction duct.
The one or more wheels on the suction duct support at least some of the weight of the product, making operation of the blower vacuum according to the present invention less tiring to a user.
As the blower vacuum is moved over the ground the wheel rotates to guide and support the blower vacuum. Additionally, the size and position of the wheels can be such that the end of the suction duct into which debris is sucked is supported above the ground at an optimum distance to facilitate good vacuuming results.
In some applications of the blower vacuum device the wheels may be a hinderance. Such applications include sucking up piles of leaves where the end of the suction duct is inserted into the middle of the pile. With detachable wheels the operator can adapt the blower vacuum to suit the job for which the blower vacuum is being used.
Preferably, the blower vacuum has one wheel. The or each wheel is preferably mounted to the side of the suction duct which lies closest to the centre of gravity of the blower vacuum when it is in vacuum mode. This provides stable support and guidance to the suction duct of the blower vacuum.
The present invention will now be described in relation to the following figures in which;
Figure 1 shows a cross sectional view of a first design of blower vacuum in vacuum mode incorporating detachable wheels.
Figure 2 shows a cross sectional view of a second design of blower vacuum in vacuum mode incorporating detachable wheels.
Figures 3a and 3b show in greater detail the clip system used to releasably attach the wheels shown in Figures 1 and 2 to the suction duct.
Figures 4a to 4c show a second clip system which can be used to releasably attach wheels to the suction ducts of the blower vacuums such as the types shown in Figures 1 and 2.
The blower vacuum device shown in Figure 1 has a motor (not shown) which is located in a housing 1 and which drives an impeller 4 located in a volute 5. The housing has a foreward handle 9a and a rearward handle 9b. The volute 5 has an air inlet 7 located in front of the impeller 4 and an air outlet 8 located radially of the impeller 4.
When the device is used as a blower, a grill (not shown) is attached over the air inlet 7 of the volute and a blower duct in the form of a tube (not shown) is attached over the air outlet 8 in a known manner. When the motor is switched on by depressing a switch 3 on the rearward handle 9a, the impeller 4 rotates and draws an airstream into the air inlet 7 and expells it radially from the air outlet 8. The user holds the device by the handles 9a and 9b with the blower duct pointing predominantly downwards to blow debris on the floor into piles.
When the device is used as a vacuum the grill and the blower duct are detached from the volute 5. A suction duct 30 is placed over the air inlet 7 and a collecting bag 22 is connected over the outlet 8 from the volute. When the motor is switched on the impeller 4 rotates and draws air and entrained debris up the suction duct and expells it radially out of the volute and into the collecting bag 22.
The user holds the device so that the suction duct 30 points predominantly downwards, as shown in figure 1, to suck up debris from the ground.
The wheel assembly shown generally by 40 is releasably attachable to the end 32 of the suction duct 30 into which the debris is sucked in a manner described in detail below with respect to
Figures 3a and 3b. The wheel assembly supports the blower vacuum above the ground with the end 32 of the suction duct 30 at a predetermined optimum distance from the ground. The support given to the blower vacuum by the wheel assembly 40 means that less support has to be supplied by an operator of the blower vacuum.
This makes the blower vaccum less tiring to operate.
The blower vacuum shown in Figure 2 is of the type disclosed in European Patent No. 657,587. It has a motor 2 which is located in a housing 1 and which drives an impeller 4 located in a volute 5.
The volute has an air inlet 7 located in front of the impeller and an air outlet 8 located radially of the impeller. A blower duct in the form of a tube 20 extends from the air outlet 8. When the motor 2 is switched on the impeller 4 rotates and draws an airstream into the air inlet 7 via air vents 6 and expells it radially from the air outlet 8.
The blower vacuum shown in Figure 2 has a blower duct 20 through which the air from the outlet 8 travels. The blower duct has a flap 18 at its end distant from the impeller 4. The flap 18 is pivotable between two positions. In a first position (shown in solid lines in Figure 2) the air flow down the blower duct is directed from the opening 38 of the blower duct 20 back along a suction duct 30 which runs parallel to the blower duct 20.
In the first position of the flap 18, the blower vacuum is in its vacuum mode. The air exiting the outlet 8 is directed by the blower duct 20 into the suction duct 30 throught the opening 38. An opening 32 at the end of the suction duct 30 distant from the impeller
adjacent to the opening 38 provides an inlet for the debris which is sucked into the suction duct 30 by an air stream created by the air entering the suction duct 30 via the opening 38. The debris is sucked along the suction duct and directed into a collecting bag 22.
A second position of the flap 18 (shown in broken lines in Figure 2) directs the air away from the suction duct 30 and out to atmosphere.
The air is directed downwardly to the front of the bottom end of the blower duct, ie. towards the ground, so that the blower vacuum functions as a blower.
The wheel assembly shown generally by 40 is releasably attachable to the end 32 of the suction duct 30 into which debris is sucked in a manner described in detail below with respect to Figures 3a and 3b. The wheel assembly supports the blower vacuum above the ground with the end 32 of the suction duct 30 at a predetermined optimum distance from the ground. The support given to the blower vacuum by the wheel assembly 40 means that less support has to be supplied by an operator of the blower vacuum. This makes the blower vaccum less tiring to operate.
Refening now to Figures 3a and 3b which show the wheel assembly 40 in more detail. At the end of the suction duct which is distant from the impeller is attached a bridge member 42. The bridge member may be formend integrally with the suction duct 30.
The bridge member is preferably located at the rear of the suction duct 30 as shown in Figures 1 and 2 (ie. at the bottom of the suction duct to the side closest to the centre of gravity of the blower vacuum).
The wheel assembly comprises wheel support arms 44a and 44b and axle 46, wheel 48 and clip attachment 50. The wheel is formed in two closed cylindrical halves 48a and 48b which are attached together, for example, by a sprung clip arrangement or by a screw thread at their interface. When formed the wheel is cylindrical with closed ends. The wheel may be rounded at the closed ends.
The wheel 48 is rotatably mounted on an axle 46. The axle is formed as a pin which is rotatably mounted through the two support arms 44a and 44b of the wheel assembly 40. The axle 46 has a head 52 at one end which fits within a recess formed in the arm 44a and has sprung arms 54 at its other end the ends of which snap fit within a recess in the arm 44b to secure the axle to the arms 44a and 44b.
The arms 44a and 44b extend from the clip attachment 50 by which the wheel assembly 40 is attached in a releasable manner to the bridge member 42 of the suction duct 30.
The clip member 50 comprises a lip 50a located at the end of a resilient portion 50b.
To attach the assembly to the bridge member 42, the clip member 50 is slid under the end 42a bridge member 42. The tapered profile of the lip 50a causes the resilient portion 50b to bend and allow the lip 50a to be slid under the bridge member 42. When the lip 50a emerges from the end 42b of the bridge member the resilient portion
SOb urges the lip 50a outwards so that it engages with the end 42b of the bridge member 42 to secure the wheel assembly to the bridge member 42. A ridge 54 on the clip member helps to hold the wheel assembly 40 in the correct position.
When the wheel assembly is to be detached from the suction duct 30, the lip 50a is depressed so that it can be slid under the bridge member 42.
Referring now to Figures 4a to 4c which show a further design of wheel assembly that can be releasably attached to the end of the suction duct of a blower vacuum.
Figure 4b shows a perspective view of the lower end 32 of a suction duct 30, such as the suction ducts shown of the blower vacuums of
Figures 1 and 2. A raised square area 70 is formed integrally towards the lower end of the suction duct 30. As can also be seen from Figure 4a, the lower side surface 72 of the area 70 is concave and the upper side surface 73 tapers slightly upwards.
Figure 4c shows a rear view of the alternative wheel assembly 40'.
As with the wheel assembly 40, the wheel 48' is rotatably mounted on an axle 46' which is itself rotatably mounted on arms 44' attached to a body portion 64.
The body portion 64 has a square apperture 60 of the same size as the raised square area 70. The lower rim 62 of the apperture 60 is convex as can be seen more clearly from Figure 4a. To attach the wheel assembly 40' to the suction duct 30 the convex lower rim 62 is fitted under the concave lower side surface 72 of the raised area 70.
The wheel assembly 40' is then pivoted about the rim 62 as indicated by the arrow in Figure 4a. The body portion 64 is thus moved towards the side of the suction duct 30 and the apperture 60 in the body portion 64 fits over the raised area 70 of the suction duct 30.
Thus, the convex lower rim 62 of the apperture 60 fits in a hinged manner in the concave lower surface 72 of the raised area 70. The body portion 64 is secured over the raised area 70 by a frictional engagement between the tapered upper surface 73 and the upper rim 63 of the apperture 60.
The body portion 64 is formed with a tapered upper end 65 which enables the user to reach his fingers between the body portion 64 and the suction duct 30 in order to detach the wheel assembly 40' from the suction duct 30.
Further alternative methods of permanently or releasably attaching the wheel assembly to the suction duct will be apparent to the person skilled in the art.
