ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to portable surface cleaning devices and more specifically to high pressure water surface cleaning apparatus. The apparatus of the present invention consisting of a vacuum header housing having secured wheels adjacent to the lower surface of the housing. A conduit is secured to the housing and at one end the conduit may be coupled to an external power washer device. At the other end of the conduit contains power spray jets whereby fluids may be ejected to the surface of a printing deck and may be mixed with a cleaning fluid for the purpose of cleaning printers ink from said surface. An operators handle extrudes from the housing and contains a fluid release control valve in which the operator may control the amount of fluids released. A suction port is also contained on the housing. The suction port is coupled to an external wet vac system by means of a vacuum hose. The wet vac draws the discharge fluids up through the housing suction port and storing said fluid in a wet vac holding tank external from the device of the present invention.
2. Description of the Prior Art
There are other portable surface cleaning apparatus designed for cleaning deck surfaces. Typical of these is U.S. Pat. No. 3,940,826 issued to Paul Phillips on Mar. 2, 1976.
Another patent was issued to William Goerss et al. on Jul. 6, 1982 as U.S. Pat. No. 4,337,784. Yet another U.S. Pat. No. 4,606,092 was issued to John J. Henning on Aug. 19, 1986 and still yet another was issued on Sep. 17, 1991 to Robert Gleadall as U.S. Pat. No. 5,048,148.
Another patent was issued to Gary Rostamo on Feb. 27, 1996 as U.S. Pat. No. 5,493,753. Yet another U.S. Pat. No. 5,706,548 was issued to Nolan Schabacker on Jan. 13, 1998. Another was issued to Dale T. Collins on May 19, 1998 as U.S. Pat. No. Des. 5,752,289 and still yet another was issued on Oct. 6, 1998 to John M. Hopkins et al. as U.S. Pat. No. 5,815,869.
Suction is generated by a blower at the rear of the recovery chamber and a shield positioned in front of the blower prevents liquid from being drawn from the recovery chamber into the blower. A pump removes liquid in the recovery chamber through a hose which empties into a remote drain. A parallel pump tubing causes recycle of liquid through the pump whenever liquid in the recovery chamber is depleted to prevent dry running of the pump. A set of spray nozzles located in the apparatus just behind the suction nozzle is connected through a hose to a faucet which acts as a remote source of clean water. The clean water supply tubing connects to the nozzles through a positive flow additive injector. The clean water supply tubing is also directly connected to the recovery tank through a bypass tubing so as to further aid in preventing dry operation of the pump and to cause additive flow even when source water pressure is low. The blower is shrouded so that air is the specification discloses a surface cleaning apparatus having a molded plastic housing and an upwardly and rearwardly projecting casing terminating at a handle, the lower portion of the housing including a forward suction nozzle, opening into a recovery chamber evacuated downwardly from the blower into the surface being cleaned. A conveniently located handle switch is wired such that whenever clean water and additive are being sprayed onto the floor, the pump also operates. A separate switch enables one to run the pump only in the event the recovery tank gets too full.
A high-pressure water cleaning device has an enclosure with an open bottom for movement over a floor surface and floor gratings. The cleaning device may be stationary, with objects to be cleaned moved past the enclosure. A rotating seal includes an upright spindle within said enclosure and secured thereto having an axial bore with a high-pressure water inlet and a series of radial discharge ports. A rotatable tubular body is journalled upon said spindle and has an internal annular high-pressure chamber communicating with the discharge ports and a series of radial outlets communicating with the chamber. Tubular arms mounting nozzles are laterally projected into said outlets for rotation with the body, the nozzles being adjusted for delivering streams of high pressure water within the enclosure at high pressure onto floor surfaces and gratings. The tubular body is power rotated. A high pressure dump valve assembly upon the enclosure receives high pressure water from a high pressure water source and has a normal mode zero pressure outlet orifice communicating with the interior of the spray enclosure and a high pressure active mode outlet which communicates with the spindle inlet for delivering high pressure water thereto. Paint is removed from floor and floor grating surfaces by directing a stream of high pressure water from said nozzles toward said surfaces. Rotation of the tubular body and closure of the dump valve outlet orifice are effected simultaneously by pneumatic activation of the cleaning device.
The disclosed spray-vacuum tool has a partitioned housing with two adjacent open faces, and defines adjacent liquid and vacuum chambers each open to both open housing faces. A pair of squeegees project beyond the open housing faces from opposite housing sides paralleling the partition and each squeegee is angled across a sharp angle corresponding to the corner angle. A pair of end guides also project beyond the open housing faces from the other interconnecting housing sides, and the squeegee ends are butted flush against the end guides. Each end guide has a flat edge to be fitted flush against one of the respective surfaces to be cleaned, and the squeegees then are flexed then against the surfaces to be cleaned. This communicates the chambers together in the region adjacent the surfaces to be cleaned, but isolates this region from the tool exterior. Nozzle means in the liquid chamber spray washing and/or rinsing liquid directly against the surfaces to be cleaned; and a source of vacuum is connected, via a hollow wand swiveled at one end to the housing, to the vacuum chamber operable to draw away the liquid spray and dirt kicked up by the spray. A brush also having the angled corner shape is supported in the liquid chamber immediately adjacent the squeegee.
A carpet cleaning apparatus consisting of a housing having a lower surface and an interior cavity. Wheels are secured adjacent to the lower surface of the housing. A conduit is secured to the housing. The conduit has a first end whereby the conduit may be coupled to a water supply and a second end with spray jets whereby fluids may be injected into a carpet. A discharge tank is secured within the interior cavity of the housing. The discharge tank has two suction ports, and two fluid inlets. Two suction conduits are provided. Each suction conduit has a first end communicating with one of the fluid inlets of the discharge tank and a second end disposed adjacent the lower surface of the housing. Two suction motors are secured in the interior cavity of the housing, each of the suction motors communicating with one of the suction inlets of the discharge tank such that a vacuum is created within the discharge tank and the suction conduits. Discharge fluids are drawn from the surface of a carpet via the suction conduits into the fluid inlets of the discharge tank.
The cleaning system has a head to which water is applied for cleaning carpets, etc. The head has a water nozzle for injecting hot water on the carpet, etc. and a vacuum inlet with vacuum hose coupled to a vacuum container. A lid having an outlet is provided for covering the top of the container. A hose is connected to the lid outlet and to a vacuum blower. A lid conduit forming the lid outlet extends through the lid with inlet openings formed through the lower portion of the outlet conduit. A chamber extends from the lower side of the lid surrounding the lower portion of the lid conduit with a bottom wall located below the lower portion of the lid conduit. A plate is connected to the bottom of the lid c
