Definitions

  • the present invention refers to a clothes drying machine, or a combined clothes washing and drying machine, provided with a conductometric type of control of the residual moisture contents of the clothes being handled.
  • Clothes drying machines with conductometric control are usually of the rotating drum or tumbling type, and comprise a control system that is adapted to measure the residual moisture contents of the clothes via sensor electrodes which the same clothes enter into contact with.
  • the conductance of the clothes is in fact used as a parameter for measuring the degree of dryness reached by the clothes, in such a manner as to be able to control the operation of the machine accordingly.
  • the sensors are arranged to drive a signal processing circuit which is generally mounted in a stationary position in the outer casing of the machine, outside of the rotating drum.
  • the sensors can be made and implemented in any of a number of possible manners.
  • they may comprise electrically conductive plaques arranged inside the drum, in correspondence of the ribs provided there in view of promoting the agitation of the clothes.
  • the sensor electrodes are constituted by respective portions of the drum which are electrically isolated from each other.
  • clothes drying and similar machines shall feature an elevated insulation class between the drum (accessible by the user) and the power supply of the processing circuit, so that the latter must comprise electric switches of an undesirably complex and expensive type.
  • the machine may be a clothes drying machine, or a combined clothes washing and drying machine, comprising an outer casing 1 which houses a rotating drum 2 that includes a plurality of clothes-agitating ribs 3 therewithin.
  • At least one (indicated at 3') of such ribs provided to improve the agitation of the clothes is preferably made as a separate component part extending, in correspondence of the inner surface of the cylindrical side wall of the drum 2, in a direction that is substantially parallel to the axis of rotation of the same drum.
  • the rib 3' may have a tapering structure, with a substantially trapezoidal cross-section and a minor base in correspondence of which there is provided at least a pair of sensor electrodes 4.
  • the electrodes 4 are in contact with the clothes whose residual moisture contents is desirably to be measured by means of a conductometric-type control.
  • the electrodes 4 are adapted to drive the programme sequence control unit 6 of the machine, which is arranged in a stationary position on the outer casing 1, with a signal that is indicative of the residual moisture contents of the clothes.
  • the electrodes 4 are adapted to drive the programme sequence control unit 6 via transceiver means or similar wireless signal transmission means, comprising a transmitter 7 of said signal, which is arranged in correspondence of the rotating drum 2 and is connected electrically to the electrodes 4.
  • Said transceiver means further comprise a receiver 12 of said signal, which is on the contrary arranged in a stationary position, relatively far from the transmitter, and is preferably incorporated in the programme sequence control unit 6 itself.
  • the transmitter 7 is preferably of the type operating on radio-frequency and is connected to an antenna 11 and respective circuitry 8-10.
  • the electrodes 4 drive the transmitter 7 via a control circuit 8 and an amplifier 9.
  • the antenna 11 is furthermore adapted to drive the control circuit 8, via a radio-frequency receiver 17, in the manner that shall be described in greater detail further on.
  • the receiver 12 is preferably of the type operating on radio-frequency and is connected to an antenna 16 so as to drive a control circuit 13 with the above mentioned signal that is indicative of the residual moisture contents of the clothes being dried.
  • the programme sequence control unit 6 is adapted to control the operation of the main operative parts of the machine, in particular in view of determining, in accordance with said signal, the end of the selected drying cycle.
  • control circuit 13 is also adapted to drive the antenna 16, via an amplifier 14 and a radio-frequency transmitter 15, as this shall be described in greater detail further on.
  • control circuits 8 and 13 preferably comprise respective microcontrollers, for instance of the type Microchip PIC12C5XX and Motorola HC05B16, respectively.
  • the circuitry associated to the transmitter 7 obviously includes also power-supply means which, in the simplest and less expensive embodiment, are preferably provided in the form of a battery 10 that is housed in correspondence of the rib 3'.
  • the transceiver 15, 17 is driven by the programme sequence control unit 6, in particular by the control circuit 13, so as to control the transmitter 7 and the related circuitry 8-11 and 17 between a stand-by state and a condition of regular power supply in accordance with the operating conditions of the machine, in a substantially per sè known manner.
  • the control circuit 13 is adapted to send to the circuit 8, via the transmitter 15, the antennas 16 and 11 and the receiver 17, a control signal that causes the entire electronic circuit 7-10 to switch over from the stand-by state to the regular power-supply state.
  • the sensor electrodes 4 detect the residual moisture in the clothes and drive the control circuit 8 accordingly.
  • the latter in turn generates the afore mentioned signal, which is amplified by the amplifier 9 and sent by the transmitter 7 to the receiver 12 via a radio-frequency link (shown schematically at 18 in Figure 1) which in an advantageous manner does not require any galvanic connection between the drum 2 and the programme sequence control unit 6.
  • the transmitter 7 and the related circuitry 8-10 and 17 are isolated in a sealed manner from the remaining part of the machine; for instance, they may be embedded in a mass of insulating resin inside the rib 3'.
  • the rib 3' is preferably made in form of a separate sub-assembly that can advantageously be mounted on the rotating drum 2 upon having been pre-assembled and pre-tested jointly with the electrodes 4, the transmitter 7 and the related circuitry 7-11 and 17.
  • the programme sequence control unit 6, instead of being provided on the outer casing 1 of the machine as described, may be arranged in a different stationary position, for instance in correspondence of a central remote control unit provided separately from the machine itself.
