Definitions

  • Vacuum cleaners usually comprise a main vacuum unit incorporating an electric motor to generate the required vacuum, together with an operating handle connected to the vacuum unit by an air-tight flexible hose.
  • the operating handle is usually connected to the actual cleaning head by a rigid pipe, although in some situations and for some uses the cleaning head may be linked directly to the operating handle.
  • the electric operating controls for the vacuum cleaner are mounted upon the main vacuum unit, which of course is separated from the operating handle by the length of the flexible hose.
  • the only control conventionally provided on the operating handle is a vacuum control which enables the degree of suction to be modified by the simple expedient of opening and closing a vent.
  • the vacuum cleaner comprises a main vacuum unit incorporating an electric motor to generate a vacuum, an operating handle remote from the main vacuum unit, an air-tight flexible hose linking the operating handle to the main vacuum unit and incorporating electric wires extending throughout the length of the hose, a source of low-voltage electrical power electrically connected to said wires, an infra-red signal transmitter electrically connected to said wires at the end thereof which is nearer to the main vacuum unit, a receiver for infra-red signals from said transmitter, electrically connected to the motor-operating circuit of the main vacuum unit, and controls at the operating handle to send an electrical signal from said low-voltage power source to said transmitter.
  • signals initiated by operation of controls mounted upon the operating handle may be transmitted fro the hose to the motor-operating circuit without there being any direct electrical connection from the hose to that circuit, and the motor may thereby be safely controlled from the operating handle.
  • the main vacuum unit itself may be any available such unit, for sample of the upright or horizontal type, but the benefits of the invention are particularly achieved when the unit is of the industrial or heavy domestic type.
  • Typical suitable units are those which are housed in an upright cylindrical housing on wheels or castors.
  • the flexible hose linking the vacuum unit to the operating handle and incorporating electric wires may advantageously be of the type sold by the company Plastiflex Ltd., in which type a pair of wires are incorporated in the windings of the hose and extend continuously throughout the length of the hose.
  • a source of low voltage electrical power Associated with the operating handle and the hose and electrically connected to the wires in the latter is a source of low voltage electrical power. While it is possible to connect in the power source at any point along the length of the wires, for example adjacent to the signal transmitter, it is much preferred for the power source to be housed in or adjacent to the operating handle. Very conveniently the power source is in the form of one or more batteries, for example of the dry-cell or rechargeable type. The voltage generated by the power source will be substantially lower than normal mains voltage, for example of the general order of 3 to 12 volts.
  • the signal transmitter is operated by electrical power from the power source, switched by means of controls mounted on the operating handle.
  • the controls may at their simplest comprise only an on/off switch but it is preferred that they be designed to send a continuous electrical signal or a succession of pulses of power to the transmitter, for example in response to pressure applied to one or more push-buttons or similar controls.
  • Such signals may, for example, make it possible for the speed of rotation of the vacuum-producing electric motor to be progressively increased or decreased.
  • an automatic switch-off device is associated with the operating controls so that, even if a push-button for example is held continuously depressed, the signal is transmitted for only a very short time. In this way, the operating life of the low-voltage power source may be prolonged significantly.
  • the signal transmitter is a transmitter of infra-red signals, which enables a signal to be transferred from the hose line to the vacuum unit without any direct electrical contact between the two components.
  • the signal receiver is designed to respond to infra-red signals from the transmitter.
  • the relative positions of transmitter and receiver will preferably be such that the signal can pass unimpeded from the transmitter to the receiver. It is preferred to provide a clear line of sight from the transmitter to the receiver. To this end, these two units are preferably located within a short distance, for example not exceeding 10 cm, of each other.
  • the receiver is preferably located within the housing of the vacuum unit and an aperture or window may then be provided in the housing to permit the signals to pass to the receiver unimpeded by the housing.
  • a signal in the near infra-red range for example having a wavelength in the range from 750 to 2500 nm.
  • the vacuum cleaner according to the present invention may be of the wet-operating or dry-operating type.
  • the invention is of particular value when the cleaner may be used alternatively for either wet or dry operation as desired, since conversion from one form of operation to the other may be carried out without any effect on the operating controls.
  • the illustrated vacuum cleaner comprises a main vacuum unit contained in a housing 3 mounted upon wheels or castors 4.
  • the vacuum unit is linked by a flexible hose 5 to an operating handle 6, which enables manipulation of a cleaning head 7 at the end of a rigid tubular pipe 8.
  • a motor (not shown) within the housing 3 is applied via the cleaning head 7 to the carpet or other upholstery being cleaned.
  • the hose 5 Within the structure of the hose 5 are incorporated two electric wires (not visible in the drawings), which run continuously throughout the length of the hose and are connected at one end to a 9-volt battery (not shown) within the operating handle 6. At the other end, the wires within the hose 5 are connected to a small infra-red transmitter 9, mounted upon the outside of the hosing connector 10. The transmitter 9 is so orientated as to direct an infra-red signal through an aperture 11 in the housing 3, towards a receiver (not shown) within the housing. Typically, the infrared signal may be at a wavelength of the order of 940 nm.
  • the receiver is incorporated in the electric circuit within the housing 3 by moans of which the vacuum motor is controlled.
  • the signal from the transmitter 9 is switched by a control switch 12 mounted upon the operating handle 6.
  • operation of the switch 12 causes an infra-red signal to be despatched by the transmitter 9 and received within the control circuit of the vacuum motor, thereby enabling the motor to be operated from the handle 6.
