Definitions

  • This invention relates to portable vacuum cleaners and, more particularly, to a vacuum cleaner capable of operating both with air and liquid cleaners.
  • Vacuum cleaners are utilized in numerous situations ranging from relatively light duty, such as the removal of crumbs and dust from a flat surface, as well as for relati­vely heavy duty operation as in the withdrawal of foreign matter embedded in carpets and upholstery. It is apparent from the wide range of cleaning tasks that some cleaning is best accomplished by the use of air alone, while other cleaning is best accomplished with the use of water or other cleaning liquid which is to be drawn by suction into the vacuum cleaner.
  • both the liquid cleaning agent and the dirt are drawn through the nozzle, in response to the vacuum, and are then deposited in a storage chamber.
  • Both the chamber and the nozzle are formed in the unitary structure of a canister which is readily secured to and removed from a housing which contains the motor and the fan.
  • the liquid and the dirt can be readily disposed of by detaching the canister from the housing, and then simply pouring out the liquid and the dirt from the canister.
  • the canister is fabricated, preferably, of a hard plastic material which may be washed so that the canister can be reused many times, thereby obviating the need for a cloth or paper bag.
  • a partial vacuum produced by the fan provides a suction passage through the nozzle into the chamber and then into the housing to the fan.
  • a structure for the deflection of the liquid away from an entry port of the housing while permitting the air to pass into the housing At an interface between the canister and the housing, there is provided a structure for the deflection of the liquid away from an entry port of the housing while permitting the air to pass into the housing.
  • the deflection structure comprises a flexible member at a posterior port of the nozzle, the flexible member closing the port except during the presence of suction forces when the member is flexed away from the posterior port so as to admit the fluids into the chamber.
  • a filter is placed at the entrance to the housing to trap particulate matter and a hood covers the top of the filter and extends forward beneath the flexible member to aid in the deflection of the liquid and dirt towards the central portion of the storage chamber, and away from the entry port to the housing.
  • the vacuum cleaner In the event that the vacuum cleaner is oriented in a non-horizontal position, at an angle of inclination suf­ficient to bring a liquid up against the filter, then some liquid is drawn through the filter to the fan.
  • a baffle which protects the motor from the liquid, the housing being provided with vents forward of the baffle through which the air and any liquid contained therein is exhausted to the exterior of the vacuum cleaner. Thereby, the motor is protected from the liquid in the event of an excessive inclination of the vacuum cleaner.
  • the deflection structure is formed by means of a deflector posi­tioned at the posterior port of the nozzle and an enclosed inlet chamber disposed in front of the filter and an air conduit of the fan housing.
  • the inlet chamber has an opening disposed near the top of the storage chamber so as to prevent the flow of liquid into the air conduit.
  • the diverter directs liquid towards the bottom of the storage chamber and away from the opening of the inlet chamber to the conduit so as to inhibit the passage of any liquid with the dirt entrained therein into the blower.
  • the cleaner 20 comprises a central housing 22 having a canister 24 affixed to a front end thereof and a handle 26 extending from the back end thereof.
  • the handle 26 is configured to be held in the hand of a person using the cleaner 20 for the cleaning of upholstery, rugs, as well as in the dusting of flat surfaces such as the top of a table.
  • the housing 22 contains a blower 28 which may also be referred to as a fan or impeller, and an electric motor 30 coupled by a shaft 32 to the blower 28. Rotation of the shaft 32 by the motor 30 imparts rotation to the blower 28 to create a partial vacuum and the accompanying suction which draws air through the canister 24 into the housing 22.
  • the motor 30 is supported within the housing 22 by ribs 34 which are disposed circumferentially around the motor 30 and contact the interior surface of the housing 22.
  • the motor 30 is powered by batteries 36.
  • a switch 38 is positioned on the underside of the handle 26 for convenient engagement by means of the finger of a person utilizing the cleaner 20. Operation of the switch 38 provides for the coupling of electric power from the batteries 36 to the motor 30 for activation of the motor 30.
  • a battery charger 40 may also be positioned within the handle 26 for recharging the bat­teries 36 during a period of nonuse of the cleaner 20, the charger being connected by a suitable electric cord (not shown) to an electrical convenience power outlet in the home or other location wherein the cleaner is to be used.
  • Electric wiring 42 connects the batteries 36 by the switch 38 to the motor 30 and also connects the charger 40 to the batteries 36.
  • the canister 24 incorporates a nozzle 44 and a storage chamber 46 disposed beneath the nozzle 44.
  • the chamber 46 will be used for the collection of any liquid cleaning agents which may be drawn in by suction into the cleaner 20.
  • the canister 24 is removably attached by a spring-clip assembly 48 to the forward end of the housing 22.
  • the canister 24 can be made of a flexible plastic configured to spring-lock the canister into its operative position.
  • a conduit 50 having an entry port 52 conducts air under suction from the canister 24 to the blower 28.
  • the entry port 52 is located at the region of an interface 54 between the housing 22 and the canister 24.
  • An air filter 56 is located at the entry port 52 for the entrapment of particulate matter which may otherwise be drawn into the housing 22 by the passage of air towards the blower 28. Air drawn in by the blower 28 passes through the blower 28 and is then exhausted from the housing 22 via exhaust vents 58 disposed in the circumferential surface of the housing 22 and, more particularly, at the bottom portion of the housing 22 to permit the escape of any liquid which may have been drawn by the air stream through the filter 56 and the blower 28.
  • the cleaner 20 includes a flapper valve 64 and a hood assembly 66, the latter including a hood 68 extending from a partition 70 downwardly over the upper portion of the filter 56.
  • the flapper valve 64 and the hood 68 in cooperation with the positioning of the chamber 46 beneath the posterior port 62 constitute a deflection structure, indicated generally by the numeral 72, for deflecting liquid into the chamber 46 and away from the entry port 52 so as to accomplish a separation of the liquid from the air as both are drawn into the cleaner via the nozzle 44 under the force of the suction developed by the blower 28.
  • air, or both air and liquid may be drawn into the cleaner 20 depending on whether the cleaner 20 is used for dry operation or wet operation. While the cleaner 20 operates well in both situations, the invention is particularly useful in the case of the utilization of liquid cleaning agents, such as water or other solvents, along with the air which carries the liquid and dirt via the nozzle 44 into the chamber 46.
  • the flapper valve 64 and the hood 68 direct liquid falling from the posterior port 62 upon the hood 68 towards the central portion of the chamber 46 and away from the entry port 52 of the conduit 50.
  • the motor 30 is protected from the liquid by a baffle plate 74 in the exhaust vents 58.
  • the baffle plate 74 extends across the housing 22 and engages with the outer surface of the front bearing 76 of the motor 30 for blocking the flow of liquid towards the motor 30 and directing such flow of liquid to the exhaust vents 58 at the bottom of the housing 22. Thereby, any liquid which fails to be caught within the chamber 46 exits the housing 22 via the vents 58.
  • the housing 22 has a generally cylindrical shape and includes ribs 78 for providing increased rigidity to the housing 22.
  • the flapper valve 64 is formed of a flexible member, such as a membrane, which is anchored at its upper edge in a bossed extending inwardly from the wall of the nozzle 44.
  • the hood 68 may be formed of metal or plastic, plastic being preferred for its resistance to corrosion.
  • the hood 68 extends into the chamber 46 from the partition 70 so as to provide a suitable flow path for liquid entrained in the air stream. The force of the vacuum is sufficient to deflect the flexible member of the valve 64 so as to open the posterior port 62 for passage of the fluids.
  • FIGs. 10-29 there is shown an alternative embodiment of the vacuum cleaner, the vacuum cleaner 220 of the alternative embodiment incorporating a further feature of the invention relating to the structure for deflecting the liquid away from the stream of air which passes on into the blower.
  • the description of the cleaner 220 closely parallels that of the cleaner 20, presented above, and, to the extent possible, corresponding structural features are correspondingly numbered with the 200 series identifying the component of the alternative embodiment.
  • the cleaner 220 comprises a central housing 222 having a canister 224 affixed to a front end thereof and a handle 226 extending from the back end thereof.
  • the housing 222 contains a blower 228 which may also be referred to as a fan or impeller and an electric motor 230 coupled by a shaft 232 to the blower 228. Rotation of the shaft 232 by the motor 230 imparts rotation to the blower 228 to create a partial vacuum and accom­ panying suction which draws air through the canister 224 into the housing 222.
  • the motor 230 is supported within the housing 222 by ribs 234-235 which are disposed circumferen­tially around the motor 230 and contact the interior surface of the housing 222.
  • the motor 230 is powered by batteries 236.
  • a switch 238 is positioned on the underside of the handle 226 for convenient engagement by means of the finger of a person utilizing the cleaner 220.
  • Operation of the switch 238 provides for the coupling of electric power from the batteries 236 to the motor 230 for activation of the motor 230.
  • a battery charger 240 may also be positioned within the handle 226 for recharging the batteries 236 during a period of nonuse of the cleaner 220, the charger being connected by a suitable electric cord (not shown) to an electrical convenient power outlet. Electric wiring (not shown) connects the batteries 236 by the switch 238 to the motor 230 and also connects the charger 240 to the batteries 236.
  • the canister 224 incorporates a nozzle 244 and a storage chamber 246 disposed beneath the nozzle 244.
  • the chamber 246 is used for the collection of any liquid cleaning agents which may be drawn in by suction into the cleaner 220.
  • the canister 224 is shown as being removably attached by means of a spring-lock configuration 248 molded into the forward end of the canister 224.
  • a conduit 250 having an entry port 252 inducts air under suction from the canister 224 to the blower 228.
  • the entry port 252 is located at the region of an interface between the housing 222 and the canister 224.
  • An air filter 256 is located at the entry port 252 for entrapment of particulate matter which may otherwise be drawn into the conduit 250 by the passage of air toward the blower 228.
  • Air drawn in by the blower 228 passes through the blower 228 and is then exhausted from the housing 222 via exhaust vent 258 disposed in the circum­ferential surface of the housing 222 and, more particularly, at the bottom portion of the housing 222 to permit the escape of any liquid which may have been drawn by the air stream through the filter 256 and the blower 258.
  • air enters the nozzle 244 via a passage 260 thereof, and thereafter flows through the passage 260 into the chamber 246.
  • the nozzle 244 is provided with a diverter 262 disposed at an exit port 264 at the posterior end of the passage 260.
  • the conduit 250 is provided with an inlet chamber 266 bounded by a front wall which forms an air-entry port 268 having an opening which is offset from the central axis of the housing 222. the opening of the port 268 is located near the top of the storage chamber 246 to prevent the flow of liquid stored in the chamber 246 from flowing into the conduit 250.
  • the diverter 266 diverts incoming liquid down towards the bottom of the chamber 246 and away from the opening of the port 268.
  • the conduit 250 is supported by a partition 270 at the front end thereof, and by a partition 271 at the back end thereof to the housing 222.
  • the air-entry port 268 in cooperation with the deflector 262 constitutes a deflection structure, indicated generally by the numeral 272, to accomplish the foregoing deflection of the liquid into the chamber 246 away from the air conduit 250.
  • the deflection structure 272 separates the liquid from the air, the liquid remaining in the chamber 246 while the air passes under the force of suction into the region of the blower 228.
  • air, or both air and liquid may be drawn into the cleaner 220 depending on whether the cleaner 220 is used for dry operation or wet operation. While the cleaner 220 operates well in both situations, the invention is particularly useful in the case of the utilization of liquid cleaning agents, such as water or other solvents, along with the air which carries the liquid and dirt via the nozzle 244 into the chamber 246.
  • the deflector 262 directs all matter entering the passage 260 downwards towards the bottom of the storage chamber 246. Liquid and any dirt entrained therein remains at the lower portion of the storage container 246 while the air under suction proceeds through a sinuous path back up to the opening of the inlet chamber 266 for further passage into the air conduit 250.
  • any particulate matter which may be carried in by the air stream is caught within the canister 224.
  • Relatively heavy particles which may have been lifted off a surface being cleaned by the air rushing into the nozzle 244 may drop out of the air stream under conditions of turbulence within the chamber 246 and be depo­sited on the bottom of the chamber 246.
  • Lighter particles carried in by the air stream advance through the chamber 246 and the entry port 268 to impinge upon the filter 256. Such particles are entrained within the filter 256 while the air advances to the blower 228 for subsequent exit via the vents 258.
  • the liquid accumulates in the chamber 246 and rises against the lower portion of the front wall of the inlet chamber 266.
  • the chamber 246 should be regarded as suf­ficiently full to require emptying of the liquid before further cleaning is attempted.
  • the canister 224 with the entry port are detached from the housing 222 to permit emptying of the contents thereof.
  • the filter 256 is exposed for removal and cleaning. It is also noted that dirt entrained by the filter 256 may fall to the bottom of the inlet chamber 266 so as to collect therein just as the liquid collects in the bottom of the storage chamber 246. Thereby, the canister 224 has accumulated both the liquid from a wet cleaning operation and dust from a dry cleaning operation.
  • the forward protrusion of the cone shaped portion of the entry port 268 would pre­vent the ingress of liquid into the inlet chamber 266.
  • the motor 230 is protected from the liquid by a baffle 274 formed in the base portion of the front rib 235, the baffle 274 extending rearwardly beneath the motor 230 to uncover vents 258 which would allow the excess liquid to be forced out with the exhaust air from the blower 228.
  • conduit 250 the supporting of the conduit 250 by front partition 270 and rear partition 271 maintains the conduit 250 positioned along the axis of the housing 22.
  • the housing 222 is advantageously strengthened by the use of ribs 278 (Fig. 12).
  • the front end of the nozzle 244 is advantageously provided with serra­tions 280 (Fig. 14) which provide for a scraping or combing function of the nozzle 244 which aids in the cleaning of fabrics.
  • the offset entry port 268 is formed with a snout 282 integrally formed on the upper portion of the front wall 284 of the inlet chamber 266.
  • a bead 286 is disposed along the rim of the chamber 266 to facilitate assembly and disassembly of the canister 224.
  • a vane 288 guides air in laminar flow through the port 268.
  • the conduit 250 (Figs. 19-22) is also provided with a bead 290 along an outer rim of the front partition 270 to aid in assembling and disassembling of the conduit 250 with the housing 222. If desired, a portion of the conic wall of the conduit 250 may be configured with different slopes to aid further in containing the liquid forward of the blower 228.
  • the rear partition 271 is configured with a relatively small central aperture 292 for engagement with the downstream end of the conduit 250.
  • the filter 256 (Figs. 25-26) is provided with a generally flat shape, a uniform thickness, and a generally rounded periphery so as to be readily inserted along the interface 254 between the canister 224 and the housing 222.
  • the blower 228 (Figs. 27-29) comprises a set of spiral vanes 294 mounted on a base plate 296 which provides strength to the blower 228, the overall configuration of the blower 228 having a shape which is readily molded.
