Definitions
- This invention relates to a tool for cleaning surfaces, and more particularly, to a tool for cleaning flooring surfaces, wall surfaces and upholstery.
- the tools utilize a cleaning fluid but do not include spray nozzles and therefore eliminate the problems associated therewith.
- the invention also relates to a method of delivering cleaning fluid to any one of a number of different tools.
- the cleaning fluid flows to the surface to be cleaned by traveling along the edge of the tool in a thin sheet, maintaining higher temperatures and allowing more complete recovery of the fluid and a reduced drying time.
- a third body of material wherein the cleaning fluid is either attempted to be deflected or otherwise controlled is illustrated hereinbelow.
- U.S. Pat. No. 4,137,600 granted to Albishausen on Feb. 6, 1970, discloses a cleaning apparatus wherein the cleaning fluid is changed into a liquid curtain by a baffle within the cleaning head.
- U.S. Pat. No. 4,649,594 granted to Grave on Mar. 17, 1987, discloses a cleaning head wherein the cleaning solution is sprayed through a narrow passage and some is wicked along the surface of the passage.
- U.S. Pat. No. 5,157,805 granted to Pinter on Oct. 27, 1992, discloses a method and apparatus for cleaning a carpet wherein the cleaning fluid is sprayed by nozzle against the back of a striker plate and then flows downwardly and through the carpet to a pickup vacuum.
- U.S. Pat. No. 5,561,884 granted to Nijland et al on Oct. 8, 1996, discloses a suction attachment spray member wherein the fluid is sprayed against the distributor plate, which creates a planar diverging liquid jet substantially filling the vacuum chamber.
- the present invention in its broadest sense deals with the distribution of fluid to a surface for cleaning purposes.
- the fluid is distributed through a slot in a manifold which is in contact with the surface and the slot is effectively at an angle to the surface to be cleaned.
- the fluid is delivered in a thin film which because of fluidic attraction follows the contour of the edge of the slot, passing through the upper surface of the carpet or fiber being cleaned without having been formed into discrete particles as with spraying, thus maintaining a hotter liquid, and also allowing a more complete pickup and/or recycle of the fluid, since a greater portion moves directly to the vacuum return, reducing the amount of fluid left on the surface because of a lesser penetration, and thus reducing the subsequent drying time.
- the current invention essentially eliminates the problem of overspray when the cleaning head is not immediately adjacent the surface to be cleaned.
- Another object of the present invention is to provide a cleaning bar which is moved over the upper surface of the material to be cleaned, the bar dispenses a cleaning fluid which penetrates the upper portion of the material dissolving the soil, which is then immediately vacuumed away, leaving a clean and substantially dry surface.
- Still another object of the present invention is to provide a distribution manifold for cleaning fluid including a lower distribution surface and a distribution slot at an angle to the surface to be cleaned, allowing the fluid to flow over the edge of the slot and into the upper portion of the surface to be cleaned in a film.
- Still a further object of the present invention is to provide a cleaning method wherein the cleaning fluid is distributed through a tubular member which is moved laterally across the surface to be cleaned, said tubular member having a longitudinal slot at an obtuse angle to the radius, allowing the fluid to be distributed as a film along the surface outside the slot and the surface to be cleaned.
- Yet another object of the present invention is to provide a cleaning system having a cleaning fluid-applying device which substantially reduces the amount of fluid left on the cleaned surface while also substantially eliminating the problem of overspray.
- Still a further object of the present invention is to delivery fluid to an adjacent surface in a thin, continuous film, controlling the amount of fluid and depth of penetration of the fluid.
- FIG. 1 is an environmental view showing a self-contained carpet cleaning apparatus, which is one type that could utilize the present invention.
- FIG. 2 is an isometric view of the cleaning head for the machine shown in FIG. 1 .
- FIG. 3 is a sectional view through the lower portion of a cleaning head showing one version of the present invention.
- FIG. 4 is a vertical section of the lower portion of a cleaning head showing another embodiment of the present invention.
- FIG. 5 is an enlarged cross-section through the fluid-applying element of the present invention as shown in FIG. 4 .
- FIG. 6 is a top plan view of a rotary cleaner which could incorporate the present invention.
- FIG. 7 is a vertical section through one of the cleaning heads in the device of FIG. 6 .
- FIG. 8 is an isometric representation of the cleaning head of FIGS. 6 and 7 further disclosing the present invention in its working environment.
- FIG. 9 is an alternate embodiment wherein the fluid delivery is adjacent the vacuum.
- FIG. 10 is yet another embodiment with the fluid delivery adjacent the vacuum.
- the cleaning system for the present invention includes a main receptacle 2 into which the soiled fluid is returned via vacuum hose 4 interconnected with nozzle 6 .
- a main receptacle 2 into which the soiled fluid is returned via vacuum hose 4 interconnected with nozzle 6 .
- the vacuum motor mounted above the receptacle 2 is the vacuum motor and the supply of a cleaning material supplied via tube 10 . It is to be understood that this cleaning system could be track-mounted.
- the carpet cleaning head 6 includes a rigid vacuum tube 12 and a rectangular, downwardly open truncated pyramidal envelope 14 which would contain the spray which is generally applied in prior known cleaning methods as well as forming the plenum for the vacuum returning the soiled liquid to the source.
- FIGS. 3 , 4 , 9 and 10 which are four separate embodiments, are the improved means for applying the cleaning fluid without the inherent problems of spray escaping.
- the front and back of the cleaning head are depicted as 16 and 18 , which with the end panels (not shown) define a rectangular lip which defines the lower surface contact area of the floor to be cleaned, which is momentarily subjected to the cleaning environment.
- Securely mounted (see FIG. 3 ) to the interior of the cleaning head is a downwardly open fluid supply means having a first wall 20 terminating in a head 22 and a second wall 24 terminating in an inwardly turned foot 26 .
- the cleaning fluid which is supplied in a steady stream downwardly between the walls 20 and 24 flows outwardly in a sheet pass foot 26 and around head 22 to be applied uniformly to the carpet or outer material, and then vacuumed up to the return tank.
- the utilization of a sheet of fluid which flows down the nozzle head eliminates the cooling of the fluid caused by transforming it from a solid into droplets, reduces the amount of fluid being used for a particular job, and further eliminates the problem of overspray should the cleaning head be inadvertently moved from the surface or tilted so one edge is raised.
- FIG. 4 A second embodiment of the present invention is shown in FIG. 4 , wherein walls 16 and 18 can again be seen, terminating adjacent the floor surface to be cleaned. Mounted between the two walls is a horizontal tube 28 having an angled slot 29 supplied by conduit 30 and mounted by means of brackets 32 , 34 within the cleaning head.
- FIG. 5 wherein the tube or manifold 28 is enlarged to show the slit or groove 29 , which is at an acute angle to the supporting floor or at an obtuse angle to the radius taken at the point of intersection with the circular cross-section. It is important to know at this point that the width of the slit 29 and the angle to the floor are critical elements in the proper functioning of the present invention and the appropriate application of the cleaning fluid.
- the present invention could be used in an alternate embodiment such as that taught by Monson in U.S. Pat. No. 4,441,229, wherein cleaning and vacuum heads 40 and 42 are mounted to a plurality of arms which are rotated about a hub 44 .
- FIG. 7 which is a vertical section through the cleaning head 40 , it can be seen that the supply conduit 28 is securely mounted between the walls 16 and 18 by brackets 46 , 48 and in contact with the floor surface or uniplanar with the bottom edges of the walls 16 , 18 .
- FIGS. 6-8 depicts six arms, two of which dispense fluid, it is to be understood that other combinations could easily be used.
- the fluid supply since it is not sprayed, need not be contained in an envelope.
- fluid flows downwardly between wall 50 which terminates in foot 52 and wall 54 which terminates in head 56 , and forms a sheet flowing over head 56 .
- the fluid is returned by vacuum between walls 54 and 58 .
- the head shown in FIG. 10 is of one piece, with the fluid exiting through angular slot 60 , flowing along bottom surface 62 , and being removed through vacuum opening 64 .
- the present invention provides a way to safely and efficiently clean carpeting and the like while reducing the heat loss of cleaning fluid used for a particular job, avoiding the problem of overspray, and, perhaps most importantly, to allow the carpet to be dried more quickly, since there is less penetration and therefore more fluid is extracted. It is further to be noted that the fact that fluid is not sprayed upon the carpet prevents it from driving the soil further into the nap.
