Definitions

  • the present invention relates generally to the floor care equipment field and, more particularly, to a floor cleaning apparatus having a nozzle assembly for cleaning a floor, a canister handle assembly with control handle pivotally connected to the nozzle assembly and an electrified stretch hose for powering a separate cleaning attachment.
  • Upright vacuum cleaners of various shapes and designs have long been known in the art.
  • Upright vacuum cleaners generally include a nozzle assembly having an intake opening, a handle assembly connected to the nozzle assembly, a suction generator for generating the negative pressure to draw dirt and debris into the vacuum cleaner and a dirt collection vessel in the form of a bag or cup for collecting dirt for disposal.
  • a nozzle assembly having an intake opening
  • a handle assembly connected to the nozzle assembly
  • a suction generator for generating the negative pressure to draw dirt and debris into the vacuum cleaner
  • a dirt collection vessel in the form of a bag or cup for collecting dirt for disposal.
  • the dimensions of the nozzle assembly and/or the weight and structure of the overall vacuum cleaner prevent its effective use in certain applications.
  • the nozzle assembly may be too wide to fit in a narrow space between a wall and a heavy piece of furniture.
  • the nozzle assembly of the upright vacuum cleaner is not particularly adapted for cleaning the treads of a stairway, the cushions of a couch, along the top of baseboards, windowsills and draperies or for other above floor applications. Accordingly, most upright vacuum cleaners are also equipped with a flexible hose and sometimes a wand as well as one or more cleaning attachments for the hose and/or wand.
  • the present invention relates to an upright vacuum cleaner equipped with an electrified stretch hose capable of powering an electric motor for driving an agitator of a cleaning tool attachment, a light or other electrical feature.
  • the rotary agitator of the cleaning tool is driven by an electric motor rather than the airflow generated by the suction generator, that entire airflow remains available to entrain dirt and debris and draw it toward the dirt collection vessel of the vacuum cleaner. Accordingly, not only is the agitator driven more powerfully and at great speeds so as to better beat dirt and debris from a surface being cleaned, but the full energy of the airstream remains available for drawing that dirt and debris to the dirt collection vessel. As a result the cleaning efficiency of the cleaning tool is greatly enhanced.
  • an upright vacuum cleaner incorporates a nozzle assembly including an intake opening and a handle assembly pivotally connected to the nozzle assembly.
  • the upright vacuum cleaner also includes both a suction generator and a dirt collection vessel. These two structures may be carried on either the nozzle assembly or the handle assembly.
  • the upright vacuum cleaner includes a flexible, electrified stretch hose that may also be carried on either the nozzle assembly or the handle assembly as desired.
  • the invention may also include an electrified cleaning wand.
  • Both the electrified cleaning wand (when provided) and the cooperating, flexible, electrified stretch hose include three insulated electrical conductors.
  • the hose also includes a reinforcing wire for strength and structural integrity and a collapsible wall that allows the hose to be stretched for added length when cleaning.
  • the upright vacuum cleaner further includes a cleaning attachment and a first connector for securing that cleaning attachment to the hose and/or the wand.
  • the cleaning attachment includes an electrical motor that receives electrical power through at least two insulated electrical conductors in the wand and the stretch hose. That electrical motor is connected to a rotary agitator carried in an intake opening in the cleaning attachment in order to drive the rotary agitator to provide more efficient and effective cleaning through the attachment than would otherwise be possible.
  • the cleaning attachment may include a booster fan and the booster fan may be driven by the electrical motor in order to provide increased suction to the cleaning attachment.
  • the cleaning attachment may include a light that receives electrical power through the two insulated electrical conductors in the wand and the stretch hose.
  • a second connector may be provided for securing the wand to the stretch hose.
  • the wand may be removed from the stretch hose and the hose directly connected to an attachment if desired.
  • the wand may include multiple sections. Those sections may be separate or alternatively may be telescoping in design.
  • the upright vacuum cleaner may also include at least one rotary agitator carried on the nozzle assembly in the intake opening.
  • the dirt collection vessel may take the form of a dirt filter bag or a dirt cup.
  • the dirt cup may be substantially cylindrical in shape and include a tangentially directed inlet opening in order to take advantage of the cleaning action produced by cyclonic airflow if desired.
  • a control switch may be provided for selectively activating and deactivating the electrical motor on the cleaning attachment. That control switch may be carried on the wand or the cleaning attachment itself.
  • a method for increasing the cleaning versatility and performance of an upright vacuum cleaner. That method comprises equipping an upright vacuum cleaner with a flexible stretch hose and a powered cleaning attachment tool that may be selectively secured to the hose and used for certain cleaning applications. That method also includes equipping the flexible stretch hose and/or a wand (if present) with electrical conductors for powering the powered cleaning attachment. In addition the method includes equipping the powered cleaning attachment with a rotary agitator and cooperating rotary agitator drive motor. Further, the method includes equipping the powered cleaning attachment with a light source so that the work area may be better illuminated so that the operator can clearly see and thereby direct the cleaning attachment to provide more effective and efficient cleaning.
  • FIG. 1 is a perspective view of an upright vacuum cleaner constructed in accordance with the teachings of the present invention.
  • FIG. 2 is a schematical view providing a further detailed illustration of the structure of the present invention.
  • FIG. 1 illustrating the floor cleaning apparatus 10 of the present invention.
  • the floor cleaning apparatus 10 is an upright vacuum cleaner. It should be appreciated, however, that the present invention could also take the form of an extractor and that the upright vacuum cleaner is merely being described in detail to illustrate the principles of the present invention.
  • the apparatus 10 includes a nozzle assembly 12 that includes an intake opening 14 .
  • the nozzle assembly also houses a rotary agitator 16 in the intake opening 14 .
  • the rotary agitator 16 may include tufts of bristles 18 or other cleaning structures such as wipers, beater bars and brushes for brushing and beating dirt from the nap of the underlying rug or carpet being cleaned.
  • the apparatus 10 further includes a handle assembly, generally designated by reference numeral 20 .
  • the handle assembly 20 is pivotally connected to the nozzle assembly 12 .
  • the handle assembly 20 includes a first housing section 22 , a second, mating housing section 24 and a control handle 25 .
  • a suction generator 26 including a cooperating fan and drive motor, is housed in a compartment within the handle assembly 20 .
  • the handle assembly 20 includes a cavity 28 that receives and holds a dirt collection vessel 30 .
  • the dirt collection vessel 30 illustrated takes the form of a dirt cup.
  • the dirt cup may include a cylindrical internal chamber and a tangentially directed inlet in order to provide cyclonic airflow and take advantage of the cleaning benefits characteristic of such airflow if desired.
  • the open cavity 28 may be replaced with an enclosed compartment that receives a filter bag in a manner known in the art.
  • the tufts of bristles 18 on the rotary agitator 16 beat and lift dirt and debris from the nap of an underlying carpet or rug being cleaned. That dirt and debris is drawn into the intake opening 14 in the nozzle assembly 12 by means of the negative pressure and the resulting airflow produced by the suction generator 26 . Accordingly, air entrained with dirt and debris is drawn through a conduit (not shown) and delivered through the wand 42 and the stretch hose 44 to the inlet (not shown) of the dirt collection vessel 30 . Dirt and debris is trapped in the vessel 30 while substantially clean air is drawn through a filter (not shown) into the compartment housing the suction generator 26 . That relatively clean air passes over the motor of the suction generator 26 to provide cooling and is then discharged through a final filter (not shown) and the exhaust port 38 into the environment.
  • the stretch hose 44 includes a flexible resin body 52 that is molded around a coiled reinforcing wire 54 , a first insulated electrical conductor 56 , a second insulated electrical conductor 58 , and a third insulated electrical conductor 60 .
  • the wall of the resin body 52 is collapsible with resilient memory to assume a retracted or shortened length.
  • the hose 44 may be stretched to a length B where B is greater than A by extending the collapsible wall of the body 58 .
  • the added length provided by the stretch hose 44 is particularly useful when trying to clean with the wand 42 and any associated cleaning attachments. This is because larger areas may be cleaned without having to move the main body of the apparatus 10 . Further, this benefit is achieved without having to store an extra length of hose since the resilient memory of the hose 44 returns the hose to a retracted condition and shorter length A when not in use.
  • the first end of the hose 44 is connected to a hose conduit or fitting 62 carried on the handle assembly 20 of the upright vacuum cleaner.
  • a two section electrical plug or junction box 64 provides the electrical connection between the upright vacuum cleaner 10 and the electrical conductors 56 , 58 , 60 of the hose 44 .
  • a connector 65 at the other end of the stretch hose 44 provides secure threaded or friction fit connection with the end of the wand 42 . Additional details relating to electrified stretch hoses 44 of the type incorporated into the present invention may be gleaned from reviewing various prior art references including, for example, U.S. Pat. No. 5,555,915 to Kanao.
  • the wand 42 includes a first section 66 and a second section 68 .
  • the two sections 62 , 68 are telescoping. More specifically, the wand 42 may be extended or retracted by depressing the actuator 70 . Once the wand 42 is extended or retracted to the desired length the actuator 70 is released to lock the wand in the desired position.
  • the wand 42 may also include a control switch 71 for selectively activating and deactivating the electrical motor 86 of the powered cleaning attachment 50 . Additional details relating to such an electrified wand 42 may be gleaned from reviewing, for example, U.S. Pat. No. 6,148,474 to Ohara et al.
  • the wand 42 like the stretch hose 44 includes a first insulated electrical conductor 72 , a second insulated electrical conductor 74 and a third insulated electrical conductor 76 .
  • a two-section junction box or plug 78 identical to the junction box 64 , bridges the connector 65 and the wand section 66 to provide electrical connection between the first insulated electrical conductors 56 and 72 , the second insulated electrical conductors 58 and 74 , and the third insulated electrical conductors 60 and 76 .
  • the powered cleaning attachment 50 includes a housing 80 .
  • the housing 80 defines an intake opening 82 .
  • a rotary agitator 84 is held in the housing 80 so as to extend across the intake opening 82 .
  • the rotary agitator 84 is rotated relative to the housing 80 by means of a drive motor 86 .
  • the drive motor 86 has a drive shaft connected to a pulley 88 which is connected by means of the drive belt 90 to a second pulley 92 that is connected to the rotary agitator 84 .
  • a gear drive or a combination gear drive and belt drive may be provided in place of the belt and pulley drive that is illustrated in FIG. 2.
  • a junction box or cooperating plugs 94 provide electrical connection between the electrical conductors 72 , 74 , 76 of the wand 42 and the electrical leads (not shown) to the drive motor 86 .
  • the drive motor 86 receives its power from the electrical wall outlet through the electrical power cord and internal wiring and circuitry in the nozzle and handle assemblies 14 , 20 of the upright vacuum cleaner, the junction box 64 , the conductors 54 , 56 , 60 in the stretch hose 44 , the junction box 78 , the conductors 72 , 74 and 76 in the wand 42 , the junction box 94 and the electrical conductors and wire leads leading from the junction box 94 to the electric motor.
  • the powered cleaning attachment 50 may include a light source 96 for illuminating the area which the operator is attempting to clean with the powered cleaning attachment 50 . That light source 96 also receives its power through the wand 42 and stretch hose 44 in the same manner as described above for the agitator drive motor 86 .
  • the drive motor 86 could also drive an auxiliary booster fan in addition to the rotary agitator 84 in order to provide additional suction at the inlet 82 .
  • the drive motor 86 may also simply be used to drive a booster fan instead of a rotary agitator 84 in the event such an arrangement were desired.
  • junction boxes 78 and 94 are identical. Further, the connector 65 will receive and hold the cleaning attachment 50 . Accordingly, the electrical or powered cleaning attachment 50 may be connected directly to the electrified stretch hose 44 if desired. Accordingly, the electrified wand 42 need not be used or even provided.
