Definitions

  • the present invention relates to a self-contained and maneuverable device using a cleaning solution formed into steam to remove residue of chewing gum and the like, or stain residue, from horizontal surfaces, including both hard surfaces such as paving or sidewalks, and soft surfaces such as a carpet.
  • the present invention provides a self contained and easily maneuverable cleaning machine creating a steamed cleaning solution to be applied to the residue or stain to be removed, but does not require external power and is well balanced so as to be easily portable and capable of use by a single person in a variety of locations.
  • Chewing gum traditionally has a base of hydrocarbon polymers mixed with sugar and flavorings, and when such gum is chewed, the inner temperature of the mouth results in softening of the gum while the sugar and flavorings are released.
  • the softened base is often discarded onto the ground where it will adhere tightly afterward, and with time the gum residue will often blacken and become rather unsightly. And, as we know, people will often step on discarded gum and carry the gum waste to adhere in another place.
  • Another device disclosed in United States patent no 7,100,540, describes a portable steam and heat generator using a backpack or truck bed for carrying a solution and fuel to be delivered to an applicator wand heating the solution to develop steam by passing the solution through a coiled pipe to be heated. Though not necessarily a steam cleaning device; this device does demonstrate structures attempting to heat a solution quickly, and near the final application of the heated solution.
  • an object of the present invention to provide a self-contained and easily portable device that can be operated easily by one person to remove chewing gum residue, or other waste product adhered to a surface, or even stains, quickly and effectively.
  • a self-contained steam cleaning device capable of steam cleaning and removal of residue such as chewing gum and the like from surfaces, includes an elongated housing preferably having wheels on a lower end portion and a handle on an upper portion, preferably an ergonomic handle, to enable the housing to be moved relatively easily by a single user.
  • a reservoir for a cleaning solution preferably an environmentally benign sugar solution, or a known cleaning solution such as Gum Remover Solution sold by Merlin Chemicals Ltd. of Liphook, Hants, of the United Kingdom, is provided within a lower portion of the housing.
  • the upper portion of the housing receives a tank for gas, preferably propane, that with the lower reservoir enables the device to be balanced easily upon the wheels when in use.
  • a vaporizing zone including a gas burner is preferably isolated within the reservoir for delivering heat to convert the cleaning solution into a steam.
  • the reservoir serves as a heat exchanger with the vaporizing zone to both preheat the cleaning solution within the reservoir and to dissipate unwanted heat from the vaporizing zone.
  • Conduit structures including a pump are provided for connecting the reservoir to the vaporizing zone to deliver the cleaning solution to the vaporizing zone. Conduit structures are also provided between the gas tank for connecting the gas tank to the gas burner in the vaporizing zone. Lastly, a brush is connected by conduit structure to the vaporizing zone and located externally at the lower end of the housing for receiving the steamed cleaning solution and applying it to the gum residue or the like.
  • the brush can be made of a material such as brass for cleaning harden surfaces such as concrete, or nylon for use indoors on such items as carpeting or flooring.
  • the reservoir includes a silica cloth insulation to aid in serving as a heat exchanger with the vaporizing zone.
  • Air for the combustion is drawn in from a front opening in the housing near the gas burner and escapes from a rearward opening.
  • the pump delivering the cleaning solution to the vaporizing zone be a battery-powered peristaltic pump providing a constant fluid pressure sufficient to drive the steam produced in the vaporizing zone to an escape tube leading to the brush.
  • the cleaning solution delivered to the vaporizing zone be the entire cleaning solution to be used for removing the residue so that no ancillary cleaning solutions need be used.
  • chewing gum residue or similar products adhering to a surface can be cleaned easily by a single person without the need for ancillary power sources.
  • the gas is ignited by a piezo ignition switch after the pump has been switched on to ensure that the cleaning solution is inside the vaporizing coil.
  • the flow is adjusted so that there is steam escaping from the nozzle and a slight hot water drip as well.
  • a 2 liter reservoir can be used that will typically last between 1.5 -2 hours depending on the required flow rate.
  • Batteries are provided for the pump and ignition; and the device may be made in two sections connected by a hinge to enable the device to be folded into a compact condition for storage and transportation.
  • Fig 1 is a prospective view of a self-contained steam cleaning device of the present invention
  • Fig. 2 illustrates the internal components thereof
  • Fig. 3 illustrates the device of Fig. 1 in its hinged condition
  • Fig. 4 illustrates an alternate embodiment of the internal components.
  • the device is shown in Fig. 1, and one person can operate the device by using the ergonomic handle 15 to guide the device so that the brass or nylon brush 7 at the opposite end can be held onto a residue of chewing gum or the like for a couple of seconds, firstly to heat the gum with the steam of a cleaning solution, and then by agitation to remove the gum.
  • a cleaning solution from reservoir 9 shown in the cut-away of Fig. 2 is pumped through conduit 5 to a small metal coil 10 of tubing that is then heated by a burner 6 fed by gas supply pipe 4 from a gas supply 1 of butane or propane to vaporize the cleaning solution.
  • Pump 13 pressurizes the conduits for the cleaning solution so that it is fed as a heated steam through reduced-diameter exit pipe 8 to the brush 7 where, with agitation, the user can soften the chewing gum residue (if it has hardened) and remove it. Or, similarly, remove stains.
  • the cleaning solution preferred is Gum Remover Solution sold by Merlin Chemicals Ltd. of Liphook, Hants, the United Kingdom; or a simple sugar solution has also been found effective.
  • the reservoir 9 for the cleaning solution has a silica cloth insulation, and is in the lower section of the device and is formed in two sections formed around the heating chamber serving as the vaporizing zone of the device.
  • the reservoir 9 holding the cleaning solution acts as a cooling medium to take some of the unwanted heat away from the heating chamber after the coil 10 is heated by the burner 6; and can serve to preheat the cleaning solution in the reservoir 9.
  • the coil 10 can be shaped in a spoon-like manner so the turns of the coil have a reducing diameter as they extend from the flame, and this allows the flame to apply heat to more surface area on the shaped coil.
  • An opening 12 serves as an exit for heat from the combustion area.
  • Fig. 4 illustrates an embodiment for the internal structures wherein the spacing A- A for the two coils 10a and 10b is 100 mm to exemplify the geometry.
  • the pump 13 preferably is a peristaltic pump to ensure a small and consistent flow is carried to the coil 10. If a diaphragm type pump were used, it may cause the cleaning solution to foam and give an inconsistent flow to the coil 10. Air for the combustion is drawn in from a front opening in the housing behind the burner 6 and escapes from a side opening 12. As shown in Fig. 4, a wind baffle 18 may be provided in a lower region of the housing serving as the exhaust to prevent back flow of air that may inadvertently cool the vaporizing zone or possibly extinguish the flame from the gas burner, or direct it away from the coil.
  • the fuel is ignited by a piezo ignition switch after switching on the pump to ensure that the cleaning solution is inside the coil 10.
  • the flow is adjusted so that approximately there is steam escaping from the nozzle and a slight drip as well, and a flow of 16-20 ml/minute has been found to be successful in providing steam and a drip of hot cleaning solution.
  • a 2 liter tank will last between 1.5 -2 hours depending on the required flow rate.
  • Batteries 2 are provided for the pump and ignition; and wheels 3 enable the device of the present invention to be maneuverable.
  • the reservoir for the cleaning solution can be filled through removable cap 11 and a control for the flow of fuel is actuated by knob 16 controlling a needle valve.
  • the device may be made in two sections connected by hinge 14 to enable the device to be folded into a compact condition, as shown in Fig. 3, for storage and transportation.
  • the gas typically propane, is delivered through a micro adjustment inlet to regulate the gas pressure.
  • the vaporizing zone includes the gas burner 6, coils 10 ⁇ and 10b, and exhaust tube 22.
  • the interconnected coils 10a and 10b form a pipe assembly delivering the cleaning solution from reservoir 9 to the gas burner 6.
  • this pipe assembly includes a first coil portion 70a serving as a vaporizing coil having the radius of turns diminishing to form a generally frustroconical configuration.
  • the gas burner 6 is positioned centrally adjacent the portion of the vaporizing coil 70a with the larger radius with the diminishing turns leading away from the gas burner 6. In this way, the flame from the burner can heat a greater surface area of the pipe assembly containing the cleaning solution to be vaporized.
  • the pipe assembly includes a non-linear conduit portion 22 leading to the turns of the vaporizing coil 70a having the smaller radius for delivering the cleaning solution to the vaporizing coil, and a heat-exchanging second coil 10b for delivering the cleaning solution to the conduit portion 22.
  • the heat-exchanging second coil 10b has the radius of turns increasing from the conduit portion to form a generally frustroconical configuration, and receives the cleaning solution through conduits from the reservoir 9.
  • the heat-exchanging second coil 10b is located to receive the exhaust from the gas burner 6 as it enters the exhaust tube 22. In this way, the cleaning solution is preheated within heat-exchanging coil 10b before being delivered to the vaporizing coil 10b. Thus, the cleaning solution is preheated in the reservoir due to the vaporizing zone being located within the reservoir, and the exhaust leading to heat- exchanging coil 10b.
  • the conduit portion 22 also serves as a heat exchanger with the exhaust from the gas burner to preheat the cleaning solution further just before it enters the vaporizing coil 10a.
  • the cleaning solution is preheated to provide a very quick transition to steam in the vaporizing coil.
  • the cleaning solution delivered to the vaporizing zone be the entire cleaning solution to be used for removing the residue so that no ancillary cleaning solutions need be used.
  • the exhaust tube 22 as shown in Fig. 4 has venting holes 24 at its end portion downstream of the burner 6, and the end portion is closed off by a rear wall 23. With baffle 18, these structures for the exhaust tube protect against back drafts when the device is used outdoors in windy conditions. The exhaust from the burner 6 will flow outwards through the holes 24 and out through vents in the walls of the housing.
  • a portion 25 of the conduit delivering the cleaning solution to the vaporizing zone extends along the exhaust tube 22 to further serve as a heat exchanger receiving heat from the exhaust tube to preheat the cleaning solution.
