Definitions

  • This invention relates to cleaning apparatus, such as a multi-function suction cleaners, having a cleaning fluid dispensing system.
  • multi-function suction cleaners having a washing mode of operation
  • the cleaning fluid or shampoo must normally be pre-mixed with water in a reservoir within the cleaner.
  • a disadvantage of this is that the correct quantity of shampoo must be pre-mixed with the water every time the water reservoir is filled.
  • Another disadvantage of known multi-function cleaners is that they do not offer a rinsing mode of operation. It has been proposed to provide a reservoir of cleaning fluid, arranged for cleaning fluid to mix with a stream of clean water being pumped to the washing head from the cleaner: these proposed arrangements have been generally complex with several flow valves through which the cleaning fluid passes; the valves are liable to become blocked when the equipment is not in use and the residual cleaning fluid in the valves dries out.
  • a cleaning apparatus comprising a cleaning fluid dispensing system which comprises a reservoir divided into two compartments by a flexible wall, a first compartment for containing cleaning fluid and having a dispensing outlet, and the second compartment having an inlet for water under pressure.
  • cleaning fluid is dispensed from the reservoir.
  • the water under pressure is branched from a main flow of water passing to the cleaning or washing head of the apparatus, and the dispensed cleaning fluid mixes with this flow downstream of the branching point in a WASH mode of the apparatus.
  • the cleaning fluid reservoir is mounted in a hand-grip, which comprises a tubular portion connectable at a first end to a flexible suction hose extending from a suction cleaner body of the apparatus and at its second end to a wand or directly to the cleaning or washing head of the apparatus (at the user's choice).
  • the hand-grip includes an L-shaped handle joined at its opposite ends to the tubular portion: preferably the second end of the latter is angled to extend generally parallel to the adjacent, first arm of the L-shaped handle. The user grips the hand-grip around the second arm of the L-shaped handle.
  • the dispensing system includes a control valve for controlling the flow of the water under pressure.
  • the water is applied to the dispenser over a branch to dispense cleaning fluid into the main flow.
  • the branch to the dispenser is shut-off and clean water only flows to the cleaning head, for rinsing purposes.
  • the branch to the dispenser is connected to the air suction stream to drain the water compartment of the dispenser and so allow the cleaning fluid compartment to expand for refilling the latter with cleaning fluid.
  • the feed of water to the dispenser and to the cleaning head and the suction to the water compartment of the dispenser are all shut-off, to provide a DRYING mode in which the apparatus applies normal suction only to the cleaning head.
  • the dispensing system is controlled by a single valve permitting one-handed operation, with the cleaning fluid mixing with the water downstream of the valve and therefore without the risk of the valve becoming blocked.
  • control valve is mounted in the hand-grip and is manually operated by an actuator (preferably a slidable trigger) also mounted on the hand-grip.
  • actuator preferably a slidable trigger
  • the actuator detents in its respective positions.
  • the actuator includes indicia or other markings visible, in each of its positions, to indicate the operating mode.
  • the reservoir is tubular in shape and the flexible wall comprises an elastomeric diaphragm sealed across one end of the compartment.
  • the diaphragm is a rolling-wall type of diaphragm, comprising a series of annular sections, one encircling another and joined together to form a convoluted configuration. Under pressure from one side of the diaphragm, the diaphragm expands along the length of the reservoir by means of the annular sections inverting: for example, they may invert one-by-one, starting with the centre section.
  • the dispensing outlet of the reservoir forms a constriction which determines the rate of flow of cleaning fluid, for a constant applied water pressure, so that the water finally passing to the cleaning head will include a constant concentration of the cleaning fluid.
  • the dispensing outlet is provided with a non-return valve.
  • a hand-grip of a suction cleaner in accordance with this invention, the hand-grip comprising an injection moulded plastics body which is formed in two halves, so as to allow components to be mounted inside the hand-grip before its two halves are joined.
  • the hand-grip includes a straight tubular portion 75 formed at one end with the tubular collar 37 which connects to a suction hose 28, and formed at its opposite end with an angled portion which terminates in an end connector 70 to which an extension tube or a cleaning accessory may be connected.
  • the hand-grip further comprises an L-shaped handle, having a first arm joined to the tube 75 adjacent the end connector 70 and a second arm joined to the tube 75 adjacent the end connector 37.
  • the first arm of the L-shaped handle lies parallel to the axis of the end connector 70 and the second arm of the handle lies substantially perpendicular to the axis of the end connector 70.
  • a slidably-mounted suction control knob 57 is mounted on the tube 75 under the L-shaped handle, to control a window allowing air to enter and reduce the suction at the inlet connector 70 if desired.
  • a passage 43 which receives water from the body of the cleaner via the fluid feed tube 50, is connected to a port 100 of a dispenser valve 55 housed within the second arm of the L-shaped handle and shown in detail in Figure 8.
  • the dispenser valve 55 comprises a piston 101 which is slidably mounted in a barrel 102.
  • An actuating rod 73 connects the piston 101 to a trigger 56 on the handle.
  • the valve further comprises a manifold 74 having three ports 103, 104, 105 which extend through the side wall of the barrel 102 and are connected to outlets 80, 81, 82 respectively.
  • O-ring seals e.g. 83 are mounted around the piston 101 at intervals along its length.
  • An annular cut-out 84 is formed in the piston 101 to connect ports 103 and 104 together when the piston is slid fully into the barrel, i.e. when the end of the piston is positioned at A ( Figure 11).
  • An elongate cylindrical shampoo reservoir 66 is disposed within the first arm of the handle of the hand-grip.
  • a removable plug 67 covers an aperture 68 for filling the shampoo reservoir 66, preferably from a sachet of shampoo.
  • a fine gauze filter 69 covers the aperture to prevent any dirt entering the reservoir.
  • a portion of the handle wall overlying the reservoir 66 is formed with a window 65 which enables the user to see how much shampoo is left within the reservoir 66.
  • An elastomeric diaphragm 64 is sealed across an end of the reservoir 66: the diaphragm 64 is a rolling wall type, moulded in a convoluted shape such that it is able to open out when unequal pressures are applied to the compartments 34, 36 on its opposite sides.
  • a pipe 58 is connected to the adjacent end wall of the reservoir 66 from the outlet 81 of the dispenser valve 55.
  • Orifice plate 62 comprises a metal disc having a small hole in its centre, the size of the hole determining the rate of flow of shampoo from the compartment 36 of the reservoir.
  • a non-return valve 63 of the duck-bill type, is mounted over the orifice plate 62.
  • FIG. 1 shows the dispenser valve set in the wash mode, by setting the piston with its end at position D. In this mode both water and shampoo are fed to the shampoo head via an outlet pipe 61. Water under pressure enters the valve barrel and passes out through ports 104 and 105 and along pipes 58 and 59. Pipe 58 is connected to the compartment 34 of the shampoo reservoir 66.
  • the water pressure on the inlet side of the diaphragm 64 is approximately 22 psi, whilst the other side of the diaphragm (in contact with the shampoo) is at atmospheric pressure.
  • FIG. 6 shows the piston 101 fully inserted into the barrel 102 to position A, to provide the drain mode.
  • the annular cut-out 84 formed in the piston 101 now connects the water space behind the diaphragm to the tube 75 of the hand-grip, by way of a pipe 71 connected to the manifold 74.
  • the nozzle of a shampoo sachet is introduced into the filling aperture 68 and squeezed by hand to refill the reservoir: this refilling is assisted in that as the diaphragm 64 collapses, fresh shampoo is drawn into the compartment 36 by suction.
  • the piston 101 is set to position C within its barrel as shown in Figure 4. In this rinse mode, water passes out of the valve 55 only through the fresh water pipe 59. No shampoo is dispensed in this mode because no water pressure is applied to the diaphragm 66 in the shampoo reservoir.
  • the trigger 56 which controls the piston 101 is slidably mounted and projects through the second arm of the L-shaped handle.
  • the piston actuating rod 73 is journalled to the trigger 56 such that sliding the trigger inwardly or outwardly moves the piston 101 into or out of the valve barrel.
  • the user places his or her index finger on the profiled inner end of the trigger 56 to move it outwards and his or her thumb on the outer end of the trigger to move in inwards: the trigger detents in each of its different positions.
  • the angled end connector 70 of the hand-grip comprises an oval-section female socket as shown in Figure 2.
  • An outlet pipe 72 is mounted to project into this socket parallel to its axis, the inner end of the pipe 72 being connected to the pipe 61.
  • the female connector 70 is arranged for receiving the male end of an extension tube or cleaning accessory.
  • two rigid extension tubes are provided with the cleaner, each having a male connector at one end and a female at the other.
  • the extension tubes connect the hand-grip to the tool being used e.g. a shampoo cleaning head.
  • the outlet pipe 72 of the hand-grip connects to a fluid feed tube running along the extension tubes.
