Definitions

  • the following invention relates to vacuum devices, more particularly, the invention relates to a vacuum cleaner that uses blown air in combination with suction to carry and collect dirt and dust.
  • Suction devices commonly work using "vacuum” (low pressure) that generates a one way flow from the cleaner head to a fluid (air is considered a fluid) cleaning system pushed out to the atmosphere. Dirt is lifted and collected due to air flow from the atmosphere to the low pressure area that is created by flow generator. Air viscosity is predominantly responsible for moving the dust and acting as a "carrier” to move the dust. The denser and more viscous the air is, the more effectively it can move the dust. Fast traveling fluid creates drag that by itself creates suction on surrounding surfaces due to the viscosity.
  • the suction effect has a short distance but wide impact on the cleaning area. Blowing fluid is denser and more viscous and not loose speed as much as suction does as the fluid becomes farther from the source of the blowing.
  • blowing air on a cleaning surface can be more effective at moving dust and dirt than suction, it is desirable to take advantage of the blowing effect to move dust/dirt.
  • fluid such as air
  • Coupled means a relationship between or among two or more devices, apparatus, components, systems, subsystems, and/or means, constituting any one or more of (a) a connection, whether direct or through one or more other devices, apparatus, components, systems, subsystems, or means, and/or (b) a functional relationship in which the operation of any one or more devices, apparatus, components, systems, subsystems, or means depends, in whole or in part, on the operation of any one or more others thereof.
  • first and second are used to distinguish one element, set, data, object or thing from another, and are not used to designate relative position or arrangement in time.
  • a suction component is arranged with an inlet and outlet, the inlet receiving air and passing the air across an opening towards an outlet, the passing of the air from inlet side to outlet side across the opening creates a blowing effect which moves dust and carries the dust to the outlet without blowing the dust away.
  • a suction device has a flow generator (2).
  • a suction component (3) is connected to the flow generator (2).
  • An inlet (12) is positioned on the suction component (3) and receives a fluid (14) from the flow generator (2).
  • An outlet (22) is positioned on the suction component (3).
  • An opening (16) in the suction component (3) is positioned between the inlet (12) and the outlet (22).
  • the fluid (14) flows through inlet to the opening (16) where it reacts with the cleaning area positioned at the opening (16), the part of fluid bounces from the cleaning area and travels to the outlet returns (24) to the flow generator through the outlet (22) with a material (18).
  • the fluid cleaning system or separator (11) can be before or after the flow generator.
  • one possible combination of elements that can make up a fluid cleaning system includes a container (10) and filter (8) located before (up stream of) the flow generator (2).
  • the main function of the bouncing of the fluid is to remove stuck and unwanted things like dust, dirt and microorganisms from objects such as a rug using high density, high velocity fluid passing fluid.
  • the fluid takes unwanted materials to the outlet. Because the suction and blowing air volume is the same through the inlet and outlet, there is very little air escaping the semi closed system.
  • Fluid with unwanted material (18) travels through the outlet (22) and through the fluid cleaning system (11) which separates the carried material (18) from the fluid (14).
  • a container (10) is downstream of the outlet (22) and receives the material (18) collected at the opening (16) such that the material (18) is transported from the suction component (3) towards the container (10) via the outlet (22) using suction created by the flow generator (2).
  • Any flow generator could be used in this system.
  • the flow generator (2) could comprises a motor (6) and a fan (4).
  • any fluid cleaning system can be positioned in any place of the device.
  • a filter (8) is located between the outlet (22) and the flow generator to separate the material (18) from the fluid (14) as shown in FIG. 1 .
  • fluid with the unwanted material (18) can be cleaned by any system including the container/filter system cleaning system or separator (11) shown in FIG 1 .
  • Other cleaning systems (11) include centrifugal, bag and filter, water or any other systems that separate the material from the fluid.
  • the material (18) Upon activation of the flow generator (2) the material (18) is moved to fluid cleaning system (11) by a combination of blowing (15) and suction (13), the blowing (15) due to the fluid (14) traveling from said inlet (12) across the opening (16) and suction (13) due to the fluid (14) being transported back towards the flow generator (2) via the outlet (22).
  • the opening (16) defines a first edge (17) and a second edge (19).
  • a separation element (20) is spaced apart from the first (17) and second (19) edges such that the first shortest distance (170) between the separation element (20) and the first edge (17) is shorter than a second shortest distance (190) between the separation element (20) and the second edge (19).
  • the inlet (14) defines a cross-sectional area smaller than that of the outlet (22).
  • the fluid converges as it moves from the inlet (12) towards the opening (16) and diverges as the fluid moves from the opening (16) towards the outlet (22).
  • the inlet and outlet have the same diameters and flow rate at a location between the flow generator (2) and the suction component (3). However this does not limit any combination of different outlet and inlet diameters or different flow rate between the inlet and outlet.
  • an exemplary fluid flow device is configured as a hand held vacuum cleaner.
  • the housing (5) of contains the flow generator (2) and the container (10).
  • the container is removable to allow the dust/dirt that is picked up to be discarded.
  • the flow generator (2) includes a motor (6) and a fan (4) which is rotated (60) by the motor (6). This generates movement of fluid (14) or air as shown.
  • the fluid (14) circulates out of the flow generator and towards inlet (12), past opening (16), outlet (22), into the container (10) and through filter (8) back past the fan (4). Air travels in semi-closed flow system that only effects the object in the opening (16).
  • the flow generator (2) is positioned between two passages that are connected to the inlet (12) and the outlet (22).
  • One side of the flow generator (2) results in low pressure which creates suction to move material from the opening.
  • the other side is used to push fluid (air) through the cleaning system.
  • the air compresses as it reaches the opening and part of the air bounces off the object to be cleaned (external surface, rug or other object). This bouncing agitates or removes dust/dirt etc. (material) from the object to be cleaned and the suction carries the material back to the cleaning system 11.
  • Air traveling from inlet directed in such way that it bounces and travels with its inertia towards the outlet by itself.
  • Suction has wider effect area allowing the suction to suck air around the opening. This combination allows limited or no escape of air in the semi-closed flow system, which enables collection of dust and dirt at the same time.
  • the circulation of the air around the system results in blowing (15) of fluid at material (24') which is located on an external surface, for example a floor or rug.
  • the blowing (15) agitates the material (24') as the suction component (3) is moved along the external surface. This agitation is as effective as rug pollination which creates a concentrated cloud of dust/dirt or material (18) within the suction component (3).
  • the flow generator (2) creates a suction force (13) or low pressure, the flow of the fluid generally moves in a semi closed circle pattern back towards the flow generator.
  • the flow (24) back towards the flow generator (2) includes material (18) lifted from the opening (16) as well as the fluid (14) which circulated past the opening (16).
  • distance (170) from the separation element (20) to the edge (17) is smaller than distance (190) between the separator and edge (19). This causes the fluid flow to converge towards the opening (16) and diverge away from the opening.
  • the cross section or average cross section of the outlet (22) may also be larger than that of the inlet (12).
  • Angle (26) may also be adjusted by changing the positioning of edge (17) and (19) relative to each other. A shallower and sharper angle may result in different agitation forces and bouncing action across the opening.
  • FIG 2B provides a configuration which may be adapted for 2mm velour carpet. Any sharper outlet angle to the opening will increase dust pushed inside a breathable object like a couch.
  • fluid flow attack angle to the surface and its power may be dependent on the composition and permeability of the object being cleaned.
  • the angle may be adjustable to suit the cleaning object, or a kit may include different fluid flow device heads that create different compression of the fluid and different angles to modify the bouncing and agitation effect of the system.
  • FIG. 2A-F shows a detail view of the vacuum head or suction component (3).
  • the Vacuum head may be connected to many different configurations of flow generators to take advantage of the suction and blowing action to agitate and collect dust/dirt.
  • the fluid compresses towards the opening (16) which results in higher viscosity to assist in moving dust/dirt.
  • FIG. 2C shows different paths parts of the fluid may take while travelling between the inlet and outlet. As can be seen, some of the fluid bounces against the cleaning surface and some air moves across the opening without bouncing against the cleaning surface.
  • the blowing via the inlet may be turned off in certain cases.
  • the housing would include an opening to the atmosphere that allows fluid to be expelled once cleaned by the fluid cleaning system or separator (11) and sucked in by the flow generator. Therefore, a cleaning surface can first be used to clean visible or loose dust/dirt and then the blowing action can be turned on to create the semi-closed system described herein which uses the blowing action to agitate the difficult to clean dirt that may be trapped, for example in a rug.
