Definitions

  • the present invention relates to programmers, used in particular in washing machines or dishes, in which the program cams, which can be driven automatically in rotation, comprise several programs established successively and a manual control element, actuable by rotation to choose one of these programs.
  • the control element is constituted by an operating button actuable in rotation in a preferential direction, integral with a first cam selection comprising as many peripheral hollows as there are successive programs on the integral assembly of the program cams.
  • the button is actuated in rotation, the first selection cam after a certain angular play, catches up with a second selection cam of identical profile, the hollows of which are then superimposed on those of the first cam.
  • the beak of a lever arranged opposite the superimposed profiles of the cams is free to fall successively into all the recesses provided on the periphery of the selection cams during their rotation controlled manually.
  • the lever controls the closing of an electrical contact triggering by a motor, the accelerated rotation of the program cams; after each fall, the lever is lifted by a relief controlling the opening of the contact and the interruption of the accelerated rotation of the program cams.
  • This programmer has drawbacks because, during the operation of selecting the selected program, the user who turns the operating button, must overcome higher mechanical resistance at the location of each selection position before which the selection cams are trained without stopping; the irregularity of the resistance encountered by the user makes it difficult to precisely position the operating button on the chosen program.
  • the successive drops of the lever in the hollow of the cams cause, in addition to a sensory inconvenience of the user, unnecessary wear of the mechanical and especially electrical elements of the programmer, whose contacts, during the maneuver, are indeed brought to close and open a large number of times causing the brief but untimely start-up of certain parts of the machine.
  • the programmer according to the invention makes it possible to avoid these drawbacks.
  • the selection means which can be actuated manually in rotation are such that the user only has to overcome a low mechanical resistance at the start of the rotation of the operating button, this rotation then being obtained by performing only a weak and constant effort, the contact triggering the accelerated rotation of the program cams being actuated only once.
  • the invention relates to a programmer as defined in the single claim, the preamble of which is based on document DE-A-2,512,900.
  • the device of FIG. 1 makes it possible to carry out the preselection of the program of a washing machine by a display maneuver requiring only a small and constant manual effort. It is in fact, by means of a mechanism simple, manually controlled by the user, to establish the power contact of an electric micromotor which by means of a mechanical reducer will drive the cam block of the programmer in continuous rotation to bring it quickly into the starting position of one of the programs initially chosen by the normal display.
  • the device controls the sudden reversal of the contact in order to restore the normal operating circuit of the programmer in step-by-step rotation by means of a suitable motor mechanism not shown.
  • the lever 3 further comprises a spout 4 having an inclined lateral flank which, by a guide opening formed in the cam 2 cooperates by engagement with a single notch formed on an annular track 10 itself secured to the cam block 9 movable in rapid and continuous rotation thanks to the gear motor 8.
  • the gear motor 8 When the latter is not powered and that consequently the cam block is immobilized in rotation by its gear with the gear motor 8, the manual force of rotation exerted on the axis 1 and the cam 2 being transmitted to the lever 3, will tend to cause the spout 4 to come out of the notch by the reaction due to the relative inclination of the bearing flanks, to bring it to the top of the track 10 by causing so displa axial cementing of the lever 3.
  • the spout 4 in addition to having an inclined flank imposing on it, during the manual display action, an axial reaction of release from the notch (FIG. 4) also has a cross section of shape. particular rounded imposing a slight radial movement of elastic reaction under the effect of the manual rotation imparted to the cam 2 from the display button acting on the axis 1.
  • This radial movement of the spout 4 is allowed thanks to a certain degree of freedom provided in the articulation of the lever 3 on the rim of the cam 2 as well as in the presence of the return spring 11 which tends, by decompression, to bring the lever 3 and its spout 4 back to the initial position.
  • An improvement in the program preselection device as described above makes it possible to manually display a position which does not exactly correspond to the start of the chosen program, but which is located in any intermediate position between two successive programs. To do this, the programmer must automatically position himself at the starting point of the program immediately following the displayed position.
  • This cam 13 has on its periphery projections in number and in angular position corresponding to each starting point of the various programs provided on the cam block 9.
