Definitions

  • the present invention relates to a switching device for an automatic washing machine programmer comprising a block of program cams, comprising at least one insulating support on one face of which are printed a series of concentric circular conductive tracks, and a series of conductive wipers arranged for respectively traversing the printed tracks during the rotation of the cam block, at least some of the printed tracks being arranged in pairs of two tracks electrically joined together.
  • Such a device is described in particular in French patent 77 02340.
  • the insulating support is rotated with the cam block, and the wipers, isolated from each other, are fixed.
  • the wipers receive connectors for connection with the other members of the washing machine.
  • Some of the tracks of this device are arranged in pairs of two tracks joined together materially, and therefore electrically, one of these two tracks being conductive only over certain segments of lengths representative of the different stages of a washing program.
  • the two trotters, associated with the two tracks of a pair of tracks materially joined together are electrically joined, as are the associated connectors, during the time intervals corresponding to the conductive segments. of one of these two tracks.
  • Such a switching device offers the advantage, thanks to the technique of printed circuits, of having a small thickness and of being able to thus reduce the size of the programmers, it nevertheless has the disadvantage of offering a program frozen at the time of the runway depot conductive.
  • the manufacturer must therefore provide, for the various machine manufacturers, as many separate switching devices and therefore deposits as its manufacturing range includes types of programmers.
  • bridges when wiring a programmer comprising such switching devices, bridges, known as wire bridges, must be made between certain outputs. When these outputs are deposited to form a strip of difficult to achieve. connection of printed circuits, this pumping operation is /
  • the present invention therefore aims to overcome these drawbacks.
  • the present invention relates to a switching device for an automatic lifting machine programmer of the type defined above, characterized in that the insulating support is fixed, the wipers are joined together and rotated with the block cams, all tracks are continuous over 360 ° and radially spaced from each other, and there are provided conductive means, connected to respective terminals and intended to be electrically joined in pairs, as well as means for interrupting the electrical connection between these conductive means during the rotation of the cam block.
  • the printing of the circuit of the conductive tracks on the insulating support is universal since all the tracks are continuous over 360 °.
  • the conductive means comprise a network of conductors printed on the other face of the insulating support, all the conductors of the network being electrically connected to all the circular tracks, respectively, preferably by metallized holes made in the holder.
  • this network of conductors can also be universal, all the conductors being for this purpose printed to be originally short-circuited.
  • the personalization of the device of the double-sided printed circuit of the invention is completed using an electrical insulator which is covered, for example by screen printing, determined portions of some of the circular tracks of the circuit for interrupting the electrical connection between the associated conductors of the network printed on the other face, during the rotation of the cam block.
  • the switching device of the invention shown in Figures 1 and 2 of the drawing, firstly comprises a rigid insulating support 11. On one side 11d of this support are printed a series of circular conductive tracks 11e, ten in the 'shown assembly, arranged concentrically around a hole 11a formed in the support 11. These tracks, which have been deposited on the support 11 by known means, are continuous over 360 ° and are radially spaced from each other.
  • each conductor 1-10 successively comprises a first rectilinear segment perpendicular to the edge 11b, starting from one of the ten connection lugs a partially curvilinear segment, and a second rectilinear segment parallel to the edge 11b and extending substantially up to to the median axis of the face 11c.
  • each conductor 1-10 corresponds to another conductor 1-10 symmetrical thereof with respect to to the median axis of the face 11c and separated from the latter by a hole 13.
  • the conductors 1-10 are spaced from each other and arranged so that a series of metallized holes 14a and 14b, formed in the support 11, electrically join the circular tracks 11e and the conductors 1-10, respectively.
  • the insulating support 11 must be considered to be universal and arranged to be able to be adapted to any desired switching cycle. It can therefore be produced in very large series.
  • FIG. 3 represents a programmer for a washing machine, to which the switching device of the invention applies particularly well.
  • This programmer comprises a block of program cams, conventionally divided into different switching modules M 1 , M 2 , M 3 in which are included large blade contacts actuated by cams for high breaking powers, and which do not cannot precisely be replaced by a double-sided printed circuit with wipers, of the type described above.
  • the block of cams, integral in rotation with an axis 17, is driven by a motor 21.
  • the switching device or module of the invention incorporated in the programmer, in addition to the insulating support 11, comprises means 16, integral in rotation with the axis 17 by a groove 16a.
  • This means 16, mounted swiveling in the hole 11a of the insulating support 11, comprises a disc 16b on which are fixed the conductive wipers 15 joined in a comb and intended to travel respectively through the circular tracks 11e printed on the face 11d of the support 11, during the rotation of the cam block.
  • the device shown comprises several insulating supports, of the type described above, two in this case, fixed in the programmer and arranged so that their respective faces 11d, on which the circular tracks are printed, are rotated one towards each other and that all of the wipers fixed on the hub 16 can cooperate with the two series of circular tracks respectively.
  • edges 11d of the two insulating supports of the programmer of FIG. 3 receive, for the connection strips 1'-10 ', connectors 19 making it possible to connect the switching device to the other members of the washing machine.
  • portions of the circular tracks 11e, associated with these six conductors 1,2,4,5,7 and 8 and participant, with the rubbers 15 asso ciés, the electrical meeting of these conductors two by two, are covered with an electrical insulator resistant to friction interrupting the electrical connection between the circular track considered and the associated wiper, and therefore between the associated conductor and another.
  • portions of the circular tracks 11e, associated with the conductors 3, 6, 9 and 10 can also, and this is generally the case, be covered with an insulator to interrupt the electrical union between one of these four drivers and one of the other six.
  • holes 18 advantageously replace bridging which would otherwise have been necessary and which have been illustrated in broken lines in FIG. 1 in a'b 'and c'd'.
  • the invention makes it possible to easily carry out all the possible combinations of bridging between the various connection terminals of the insulating support, before being mounted in its switching module.
