Definitions

  • the present invention relates to a control device, particularly but not exclusively useful for appliances used in the field of domestic and/or industrial cleaning.
  • a wide variety of models of cleaning appliance is currently commercially available, ranging from vacuum cleaners to steam cleaners, irons, combined appliances and others used for cleaning in the home and in public places, such as restaurants, industries, shopping centers, et cetera.
  • a first construction type provides for a body of the appliance which accommodates the boiler and is extended, for steam dispensing, by means of a hose which ends, at its free end, with a handle which is adapted to control the movement of the possibly replaceable tool of the steam appliance.
  • switches are accommodated at the handle and, by means of electrical connecting wires arranged inside the hose, are connected to an electric valve which in turn controls the flow of steam or other auxiliary functions.
  • connection between the switches and the electric valve occurs substantially at the mains voltage (220 and 110 V) and therefore with considerable danger for the user.
  • this first construction type besides still not ensuring perfect safety of the controls available to the user, leads to high manufacturing costs.
  • a second construction type meant to obviate the drawbacks noted as regards the first construction type again provides for switches which are accommodated in the handle of the tool, but said switches are connected at low voltage (12-18 V) with an electronic board or simply with a transformer, accommodated inside the body of the appliance.
  • a third recent type accommodates, inside the handle, a wheel which controls a cable which slides within a sheath which is in turn accommodated inside the steam connection hose.
  • the cable reaches inside the body of the appliance, in which it controls the opening or closure of an electric valve.
  • this third construction type obviates the problem of safety due to the circulation of electric current proximate to the handle, it has characteristics of poor reliability under prolonged and intense use; moreover, experience in the field has shown that it is awkward for the user.
  • Another construction type provides for a pneumatic connection between a control located in the handle and a transducer located in the appliance body and preset to control the various functions thereof.
  • Cleaning appliances particularly vacuum cleaners, have been recently devised which use an infrared remote control located in the handle and a receiver located in the appliance body.
  • the aim of the present invention is to provide a control device, particularly for appliances used in the field of cleaning, which solves the above-noted drawbacks of conventional devices, particularly obviating completely the problem of user safety.
  • an object of the present invention is to provide a control device which is constructively simple and adaptable to the various models of appliance currently provided for specific uses.
  • Another object of the present invention is to provide a control device which can be operated easily and ergonomically by the user.
  • Another object of the present invention is to provide a control device which leads to production costs and times which are competitive with respect to conventional devices.
  • Another object of the present invention is to provide a control device which can be manufactured with known technologies.
  • a control device particularly for appliances used in the field of domestic and/or industrial cleaning, characterized in that it comprises at least one radio-wave transmitter which is located on the handle of the tool of the cleaning appliance and a receiver which is located on the appliance body and is connected to means for controlling the various functions of the appliance.
  • the transmitter on the handle can be combined with a receiver and the receiver on the appliance body can be combined with a transmitter.
  • a control device particularly for appliances used in the field of domestic and/or industrial cleaning, according to the invention, is in this case part of an appliance such as a vacuum cleaner, generally designated by the reference numeral 10 and provided with a body 11 which accommodates per se known suction means, not shown for the sake of simplicity, and to which a flexible hose 12 for the passage of the aspirated air is connected, in this case detachably; a handle 13 is fixed, likewise detachably, to the free end of the hose, and working tools, generally designated by the reference numeral 13a, can be connected to the handle.
  • an appliance such as a vacuum cleaner, generally designated by the reference numeral 10 and provided with a body 11 which accommodates per se known suction means, not shown for the sake of simplicity, and to which a flexible hose 12 for the passage of the aspirated air is connected, in this case detachably; a handle 13 is fixed, likewise detachably, to the free end of the hose, and working tools, generally designated by the reference numeral 13a
  • the control device comprises a radio-wave transmitter 15 which is located on the handle 13 and a receiver 16 which is arranged on the appliance body 11 and is connected to the means for controlling the various functions of said appliance, for example control switches 11a, timers, power regulators, et cetera.
  • the transmitter can be associated with various buttons 17, each for a specific function.
  • the transmitter 15 is arranged inside a box-like body 14 and is integrated in a board 19 which comprises a removable power supply battery 18, a microprocessor 20, one or more keys 17 and LEDs 21.
  • the receiver 16 is instead integrated in a board 22 with a microprocessor 23 and a memory 24.
  • the microprocessor 20 runs an algorithm and randomly assigns itself any one of a plurality of preset codes for being recognized by the appliance; this code remains active until the battery 18 is removed or becomes drained.
  • the board 22 installed in the appliance presets itself to recognize any one of the provided radio controls that is activated within a certain time period (for example a few tens of seconds).
  • the transmitter 15 is activated by pressing one of the control buttons 17, and the appliance stores, by means of the memory 24, the identification code sent by the transmitter 15 that has activated and stores it in memory until the tuning operation is performed again (this also occurs if the machine is switched off or disconnected from the power supply).
  • the appliance can be operated prior to sale and therefore that encoding must be performed directly by the user and that nearby users using identical appliances are not mutually affected by the signals.
  • a transceiver is provided both on the handle 13 and on board the appliance.
  • the automatic recognition function remains the same, but every time there is a status variation the appliance transmits to the radio control the new operating mode.
  • the device according to the invention fully solves the problem of user safety while ensuring easy use and structural strength.
  • the transmitter 15 can be inserted in the handle 20 of an iron 21 which can be connected to the appliance.
  • the materials and the dimensions may be any according to requirements.
