Abstract
A surface cleaning appliance incorporating a flexible hose. The hose is a stretch hose, which is extendable lengthways from a retracted length to an extended length under a tensile force applied to the hose, the extended length being at least 25% longer than the retracted length. A length of the hose has a hose wall formed at least in part by a layer of fabric which is sealed to form an impermeable barrier for the fluid carried by the hose, and which therefore provides a layer which is both impermeable and has a high resistance to cyclic fatigue.
Description
- This application claims the priority from UK Application No. 0912838.0, filed Jul. 23, 2009, the entire contents of which are incorporated herein by reference.
- The present invention relates generally to surface cleaning appliances having an extendable flexible hose, or so-called “stretch” hose, possibly provided as part of a hose and wand assembly for the appliance.
- Domestic vacuum cleaners, namely those vacuum cleaners which are intended for domestic use, generally fall into two categories: “cylinder” cleaners and “upright” cleaners.
- In a typical cylinder cleaner a, shown in
FIG. 1 , a main body b of the cleaner a is fluidly connected to a floor tool c via a hose and wand assembly. The hose and wand assembly consists of a relatively in-extendable, flexible hose d which is connected at one end to a suction inlet on the main body b, and a rigid, hollow, telescopic wand e which connects the opposite end of the flexible hose d to the floor tool c. During normal operation of the cleaner a, a user grasps the wand e manually to maneuver the floor tool c across the floor, dragging the main body b behind with the in-extendible, flexible hose d. - In a typical upright cleaner f, shown in
FIG. 2 a, a cleaner head g is permanently attached to the main body h of the vacuum cleaner and the user maneuvers the cleaner head g and the main body h together across the floor using a handle i. Historically, only cylinder cleaners were provided with a suction hose: upright cleaners relied solely on the cleaner head permanently attached to the main body of the cleaner. More recently, manufacturers have started to provide upright vacuum cleaners with a hose and wand assembly, in addition to the cleaner head, so that the upright cleaner can optionally be operated in the manner of a cylinder cleaner.FIG. 2 b shows a particularly compact form of hose and wand assembly, used generally on models from the Dyson range of upright vacuum cleaners, in which a telescopic wand j is integrated with the handle i and can be released from the main body h by operating a catch. A so-called “stretch” hose k attaches the wand j to a suction inlet (not shown) on the main body h; the stretch hose k is stored on-board the main body h in a retracted position and can then be manually extended, or “stretched”, as desired following release of the wand j (with the handle i) in order to increase the useful reach of the wand j. A suitable floor tool l can be attached to the suction inlet on the wand j, as desired. - Hoses for early models of cylinder cleaner were often constructed using rubber, an example of which is described in UK Patent No. GB836407. These rubber or rubber-based hoses were, however, superseded relatively quickly by plastic suction hoses, typically comprising a molded thermoplastic hose wall having a series of corrugations to provide the requisite flexibility for the hose, as appropriate. The use of plastic significantly reduces the weight of the hose compared to a corresponding rubber or rubber-based hose, and the molded plastic suction hose has become the well-established industry norm for domestic vacuum cleaners, whether in the form of a relatively in-extendible suction hose on a cylinder cleaner or a stretch hose on modern upright cleaners.
- Molded plastic hoses are also commonly used as a suction or blow pipe in industrial (non-domestic) surface-cleaning appliances, and are used in other fields in which it is likewise desirable to provide a hose which is relatively lightweight and low-cost to produce.
- An object of the present invention is to seek to provide a surface-cleaning appliance incorporating an improved stretch hose, possibly as part of a hose and wand assembly for the appliance, which offers an advantageous alternative to the conventional molded plastic stretch hose commonly used on upright domestic vacuum cleaners.
- According to the present invention there is provided a surface-cleaning appliance, preferably a domestic vacuum cleaning appliance, comprising a flexible hose, a length of the hose being extendable lengthways from a retracted length to an extended length under a tensile force applied to the hose, the extended length being at least 25% longer than the retracted length, wherein said length of the hose has an extendable hose wall formed at least in part by one or more layers of fabric, at least one layer of fabric being sealed to form an impermeable barrier for the fluid carried by the hose.
- The present invention is concerned with stretch hoses, which have an extended length which is significantly longer than their retracted length in the context of the use of the hose. Thus, the extended length will be at least 25% longer than the retracted length (e.g. an extended length of 125 cm versus a retracted length of 100 cm), but may typically be in the range of 2 to 6 times the retracted length of the hose, and possibly up to 20 times the retracted length of the hose.
- The hose may be extendable in response to a manual tensile force, for example a force exerted manually by the user of a vacuum cleaner.
- The use of a fabric stretch hose in particular breaks with the long-established industry norm for domestic vacuum cleaning appliances, which have almost exclusively continued to rely on conventional molded plastic hoses. In such conventional molded plastic stretch hoses, it has been found that the hose wall can suffer from cyclic fatigue caused by repeated extension and retraction of the hose, increasing the risk of the hose splitting. The fatigue life of the hose can be increased by increasing the thickness of the hose-wall, but this often carries with it a weight penalty, and may also critically reduce the flexibility and/or extensibility of the hose in certain applications. The use of a fluid-tight fabric layer in accordance with the present invention is aimed at providing a layer which is both impermeable, highly flexible and has a relatively high tolerance to cyclic fatigue, thus advantageously improving the useful life of the hose as compared to a comparable, conventional plastic hose, without critically affecting the flexibility or weight of the hose.
- The hose wall may be a fabric hose wall i.e. constructed solely from one or more layers of fabric. This sort of fabric construction offers a lightweight, highly flexible alternative to a conventional molded plastic hose offering comparable fatigue life.
- One or more of the layers of fabric may be substantially inelastic, and may incorporate sufficient slack for non-elastic lengthways extension of the hose wall from the retracted length to the extended length. At least some of the slack may conveniently be provided by a series of corrugations or folds in the fabric.
- The fabric hose-wall may comprise woven, braided or knitted plastic or plastic coated filaments.
- The hose wall may incorporate at least one layer of ripstop fabric, being a fabric which is interwoven with a pattern of reinforcing yarns, typically a cross-hatch pattern, and which consequently exhibits high resistance to the formation and spread of tears and runs in the fabric. The ripstop fabric may be ripstop nylon or ripstop polyester, but the invention is not limited to any particular fabric. The reinforcing yarns in the ripstop fabric do not necessarily need to be the same material as the bulk fabric.
- The layer of ripstop fabric provides a tear and puncture resistance layer in the hose-wall. The layer of ripstop fabric itself may be relatively thin, possibly less than 0.1 mm in the case of a hose for a domestic vacuum cleaning appliance, and therefore does not add any significant weight to the hose. The ripstop fabric is also highly flexible.
- The hose-wall may be supported on one or more frame elements, providing increased crush strength and stiffness for the hose. This helps to maintain an open flow passage through the hose.
- The frame elements are arranged for lengthways movement relative to one another to accommodate extension of the fabric wall from the retracted length to the extended length. The frame elements may be resiliently connected to one another for providing a restoring force to return the fabric wall from the extended length to the retracted length.
- One or more of the frame elements may be sandwiched radially in-between either two separate layers of fabric in the hose wall or, alternatively, two plies of fabric (which may be formed by doubling over a single layer of fabric), so that the frame element(s) is (are) not exposed on the outside of the hose wall.
- During use of the hose, frictional wear of the fabric may occur, principally along the contact interface between the frame elements and the fabric, which may eventually lead to breach of the hose wall (and consequent loss of suction in the case of a suction hose for a surface cleaning appliance). The provision of two sandwiching layers or plies of fabric reduces the effect of this frictional wear by increasing the effective thickness of the hose wall. At the same time, providing the inner sandwiching layer (or ply) on the inside of the frame element has the advantage that this inner sandwiching layer is not exposed to the relatively high levels of frictional wear which typically occur around the outside of the frame elements.
- The layers or plies of fabric may be bonded to one another, axially either side of the respective frame element, to encapsulate the frame element between the layers or plies of fabric, thus conveniently retaining the frame elements in their predetermined positions. The fabric making up the hose wall may additionally or alternatively be arranged to form a multi-ply or multi-layer overlap around the outside of one or more of the frame elements, further improving the external wear resistance of the hose.
- It has also been found that coating the frame elements with a relatively compliant or low-friction material (i.e. compliant or low-friction relative to the material making up the frame elements) has a significant effect on the wear resistance of the hose. For example, if the frame elements are steel, the wear resistance of the hose can be improved significantly by coating the frame elements with a plastic e.g. polyurethane (PU), thermoplastic polyurethane (TPU) or polytetrafluoroethylene (PTFE)
- The hose wall may comprise a wound fabric tape. In a particular embodiment, the hose wall comprises a wound fabric tape, and one or more of the frame elements are sandwiched radially in-between two axially-overlapping passes of the wound fabric tape. The respective overlapping passes of the fabric may be bonded to one another, axially either side of the corresponding frame element in order to encapsulate the frame element. Additionally or alternatively, the wound fabric tape may be arranged so that two or more axially overlapping passes if the fabric tape form a respective multi-ply overlap around the outside of one or more of the frame elements. These winding arrangements are considered to be particularly effective for reducing the effects of frictional wear; this is particularly the case during use on a typical domestic vacuum cleaning appliance, where preliminary tests indicate that winding a ripstop fabric tape in the manner described above can dramatically increase the life of the hose compared to a conventional molded plastic hose. The winding arrangements described above also present a relatively smooth internal surface to the hose, tending to limit the thickness of the boundary layer flow through the hose.
- The hose-wall may be bonded to the frame elements, for example using an adhesive. If the frame elements are formed from an electrically conductive material, the adhesive may be cured by resistance-heating the frame elements.
- The frame elements may be coils on a helical supporting member, which may be a helical metal wire. The fabric may conveniently be wrapped around the helical supporting member using any suitable wrapping arrangement.
- Embodiments of the invention will now be described with reference to the accompanying drawings, in which:
-
FIG. 1 is a schematic, perspective view of a conventional cylinder cleaner incorporating a flexible suction hose; -
FIGS. 2 a and 2 b are schematic, side views of a conventional upright cleaner incorporating a flexible suction hose; -
FIG. 3 is a schematic perspective view of a retracted length of flexible, extendable hose in accordance with the present invention; -
FIG. 4 a is a sectional view of the hose shown inFIG. 3 , taken along the line A-A; -
FIG. 4 b is a sectional view corresponding toFIG. 4 a, but showing the hose in an extended configuration; -
FIG. 5 is a sectional view showing an alternative form of hose in accordance with the present invention, in which the hose wall has a multi-layer fabric construction; -
FIG. 6 is a sectional view showing an alternative form of hose, in which the hose wall is constructed from wound fabric tape; -
FIG. 7 is a sectional view through part of the fabric hose wall shown inFIG. 6 ; -
FIG. 8 is a sectional view through a length of hose, illustrating an alternative hose wall configuration utilizing a wound fabric tape; and -
FIG. 9 is a sectional view through a length of hose, illustrating a further alternative hose wall configuration utilizing a wound fabric tape. - Referring first of all to
FIG. 3 , an extendable length of hose 1 comprises a hose-wall 2 which is supported on a helical supportingmember 3. - The helical supporting
member 3 is resiliently extendable lengthways (along the axis x inFIG. 3 ) from a retracted length Lr, shown inFIG. 4 a, to an extended length Le, shown inFIG. 4 b. - The
hose wall 2 consists of a single layer of substantially inelastic fabric, which is sealed to prevent escape of fluid through the hose-wall 2. The hose-wall 2 thus represents an impermeable barrier for containing a fluid under transport, indicated by the flow arrow A through the hose 1 inFIG. 4 b. The fabric may be ripstop fabric, for example ripstop Nylon or polyester. - The fabric hose-
wall 2 is secured to the helical supportingmember 3, but is provided with sufficient axial slack to accommodate substantially non-elastic lengthways extension from the retracted length Lr to the extended length Le. Thus, with the helical supportingmember 3 at its retracted length Lr, the fabric hose-wall forms a series of corrugations in between the successive coils of the helical supportingmember 3, which corrugations are then taken up during lengthways extension of the hose-wall to the extended length Le, as illustrated inFIG. 4 b. The fabric hose-wall 2 may be arranged to fold along pre-determined lines, so that the hose-wall tends to form a series of tighter, predefined folds between successive coils of the helical supportingmember 3 rather than the more ‘loose’ corrugations shown inFIG. 4 a. - The
fabric hose wall 2 may be sealed by impregnating, spray-coating or dip-coating the fabric with a sealant such as polyurethane (PU), a thermoplastic polyurethane (TPU) or polyvinyl chloride (PVC), or in general by using any suitable plastification process. - The fabric may be sheet fabric, produced for example by weaving, braiding or knitting, in which case the sheet fabric may be wrapped around the outside of the helical supporting
member 3 to form the tubular hose-wall 2. The fabric may be wrapped tightly to form a compression-fit on the helical supporting member 3 (but still providing the necessary axial slack for lengthways extension of the hose wall 2). The hose-wall 2 may be securely bonded to the helical supportingmember 3, for example using a heat-curable adhesive such as a suitable solvent-based or epoxy adhesive, which may be applied to one or both of the hose-wall 2 and the helical supportingmember 3, possibly as a pre-coating prior to wrapping of the fabric. If the helical supportingmember 3 is in the form of a coil of metal wire, the adhesive may conveniently be heat-cured by resistance-heating the wire using a suitable electric current. - In an alternative arrangement, the ripstop fabric is produced as a seamless, tubular fabric, produced for example by tubular-weaving, tubular-braiding or tubular-knitting, and the hose-
wall 2 is formed by rolling the fabric tube lengthways onto the helical supportingmember 3. A pre-form fabric tube may also be produced from sheet fabric by initially wrapping the fabric around a cylindrical mandrel and bonding the sheet fabric along a seam to form the tube. Again, the relative diameter of the hose-wall 2 may be controlled to form a slight compression-fit on the helical supportingmember 3 and the hose-wall may be securely bonded to the helical supportingmember 3 using a heat-curable adhesive. - In
FIGS. 4 a and 4 b,successive coils member 3 constitute a continuous set of frame elements for supporting the hose-wall 2.FIG. 5 shows an alternative arrangement, in which a length ofstretch hose 10 has a hose-wall 20 supported on a non-continuous set of frame elements, in the form of individual frame rings 30 which are bonded separately to the inside of the hose-wall 20. - The
stretch hose 10 is shown at an extended length Le inFIG. 5 , with the hose-wall 20 being pulled taut between the frame rings 30, under the tensile force T. The frame rings 30 are separate from one another and do not therefore provide any restoring force for returning the hose to a retracted length. A suitable restoring force may nevertheless be provided, if desired, by using an elastic fabric in thehose wall 2. Upon return of the length ofhose 10 to its retracted length, thehose wall 20 assumes a corrugated profile, similar to the profile of thehose wall 2 shown inFIG. 4 a. - The hose-
wall 20 has a multi-layer fabric wall construction, consisting of an intermediate layer offabric 20 a sandwiched between an inner and outer layer offabric fabric layers layers wall 20. - Each of the layers of
fabric fabric layer 20 a may be formed as a seamless, tubular fabric, and thelayers tubular fabric layer 20 a. The fabric layers 20 a, 20 b, 20 c may be bonded to one another using a heat-curable adhesive, which may be cured by resistance-heating eachframe ring 30 separately, possibly using some sort of switching circuit. Alternatively, where surface-sealing of the layer or layers of fabric, 20 a, 20 b, 20 c is by impregnation, the impregnating sealant may also be used effectively to bond the fabric layers 20 a, 20 b, 20 c. -
FIG. 6 is a sectional view illustrating a multi-layer fabric hose wall formed using two ripstop fabric tapes 200 and 201. - Each of the fabric tapes 200 and 201 is wound around to form a respective fabric layer along the length of the helical supporting
member 3. In the case of the fabric tape 200, this forms arespective fabric layer 210 on the outside of the helical supportingmember 3 consisting of a series of axially-overlapping passes offabric respective fabric layer 211 on the inside of the helical supportingmember 3 consisting of a series of overlapping passes offabric - The
coils member 3 are sandwiched radially in-between the twofabric layers coil 3 a is sandwiched between thepasses coil 3 b is sandwiched between thepasses coils coil 3 a, the overlapping passes 200 b and 200 c form a double-ply overlap on the outside of thecoil 3 b and so on. In the arrangement shown inFIG. 6 , overlapping passes of the fabric tape 201 additionally form corresponding double-ply overlaps on the inside of thecoils member 3 are considered to be particularly advantageous for a suction hose on a domestic cleaning appliance, because they are associated with regions of the hose-wall that are typically subject to relatively high frictional wear. - The fabric tapes 200, 201 may be pre-wound on a mandrel and then fitted onto the helical supporting
member 3 in similar manner to a pre-form fabric tube, possibly following bonding of the overlapping passes of fabric to consolidate the pre-wound configuration of the fabric tape. - The overlapping passes 200 a, 201 a are bonded to one another axially either side of the
coil 3 a, as indicated by the vertical dotted lines inFIG. 7 , in order to encapsulate thecoil 3 a between the fabric tapes 200, 201. In addition, thepasses passes - The fabric tapes 200, 201 are wound around the helical supporting
member 3 with the helical supporting member stretched to its extended length Le, shown inFIG. 6 , under an applied tensile force. Following winding of the fabric tapes 200, 201 the applied tensile force is then removed, and the helical supporting member returns to its retracted length, with the hose wall assuming a generally corrugated profile, similar to the profile of thehose wall 2 inFIG. 4 a. -
FIG. 6 illustrates one possible winding arrangement using fabric tape, but other arrangements are possible. Thus, inFIG. 8 , a singleripstop fabric tape 203 is wound onto the helical supportingmember 3, along the direction x, with a trailing portion of thefabric tape 203 running around the outside of thecoils fabric tape 203 running around the inside of thecoils coils single fabric tape 203, without the need for a second fabric tape. For example, thecoil 3 b is sandwiched between overlapping passes 203 a and 203 b, which may be bonded to one another axially either side of thecoil 3 b in order to encapsulate thecoil 3 b in position. - A single ripstop fabric tape may be wound additionally to form a multi-ply overlap on the outside of a frame element.
FIG. 9 illustrates one such “dual function” winding arrangement; the arrangement shown inFIG. 9 is similar to the arrangement shown inFIG. 8 , but utilizes a relatively wideripstop fabric tape 204 additionally to form a series of double-ply overlaps on the outside of thecoils ripstop fabric tape 204 is arranged such that each of thecoils fabric tape 204, while the second overlapping pass additionally overlaps a third pass of thefabric tape 204 to form a double-ply layer overlap on the outside of the coil. For example, thecoil 3 a is sandwiched between successive overlapping passes 204 a and 204 b, whilepass 204 b additionally forms a double ply overlap with successive overlappingpass 204 c. The overlapping passes 204 a and 204 b may be bonded to one another axially either side of thecoil 3 a to encapsulate the coil in position. In addition, the overlapping passes 204 b and 204 c may be bonded to one another in the region of the respective double-ply overlap. - Although in the embodiments described, the frame elements are located on the inside, or encapsulated within, the hose-wall, the invention is not intended to be limited to such arrangements and the frame elements may alternatively be provided on the outside of the hose wall.
- The invention concerns a surface-cleaning appliance, preferably a domestic vacuum cleaning appliance. The hose may be incorporated as part of a hose and wand assembly for the appliance, and in any event may be fitted to a main body of the appliance using conventional fittings. The main body of the appliance may in particular be a conventional upright body on a domestic upright cleaner, such as the main body h in
FIGS. 2 a and 2 b. - Although in the embodiments described the hose incorporates a fabric hose-wall i.e. a hose wall constructed entirely from one or more layers of fabric, in its broadest sense the invention is not limited to arrangements wherein the stretch hose has a fabric hose-wall. The hose wall may, for example, additionally incorporate an extruded or injection-molded plastic protective sheath or lining. Nevertheless, it is believed that the use of an impermeable fabric layer in the hose-wall will improve the resistance of the hose wall to cyclic fatigue and thus improve the useful life of the hose as compared to a conventional extruded or injection-molded plastic stretch hose.
