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 which can be actuated in rotation in a preferential direction, integral with a first selection cam comprising as many peripheral depressions 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 disposed opposite the superimposed profiles of the cams is free to fall successively into all of the recesses provided on the periphery of the selection cams during their manually controlled rotation.
  • the lever controls the closing of an electrical contact triggering by a motor, the accelerated rotation of the 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 chosen program, the user who turns the operating button, must overcome higher mechanical resistance at the location of each selection position in front of which the selection cams are driven 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 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 programmer object of the invention, comprises a rotary selection member secured to an operating axis, the angular positioning of which makes it possible to choose one of the successive programs from all of the program cams, themselves capable of be moved automatically in rapid and continuous rotation; it further comprises, a control member cooperating with said rotary selection member and axially movable relative to said set of program cams, means for causing the axial displacement of said control member in one or the other of the two positions with respect to said set of program cams, a first and a second contact with which said control member cooperates indirectly respectively in a first and a second position and means for allowing the rotary drive of said selection member by said movable control member acting in said first position.
  • the device of FIG. 1 makes it possible to carry out the program preselection of a washing machine by a display maneuver requiring only a small and constant manual effort. It is in fact, by means of a simple mechanism, controlled manually by the user, to establish the power contact of an electric micromotor which by means of a mechanical reduction gear will drive in rotation continues the programmer's cam block to quickly bring it into the starting position 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 supplied 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 thus the axial displacement 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 that 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.
  • Improvement of the preselection system for the program 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.
