Definitions

  • Such a device is used in particular on programmers of washing machines.
  • the displacement of the movable contact in the starting position aims at establishing the supply contact of an electric micromotor which by means of a mechanical reduction gear will drive in continuous rotation the set of cams, or the cam block of the programmer. , to quickly bring it to the starting position of one of the programs initially chosen by the normal display.
  • the device controls sudden reversal of the contact in order to restore the normal operating circuit of the programmer in step-by-step rotation.
  • the axial movement of the control member determined at the end of the take-up course, be carried out clearly and almost instant.
  • the control member is a control lever provided with an end spout which can fall into a notch on a circular track of a cam for starting the cam block. So that the reversal of the contact is rapid, it is planned to give the spout and an associated light on the selector element a particular shape, which prohibits the engagement of the spout in the notch before the angular position of the cam block did not join and therefore exactly coincides with the displayed starting position of the selected program.
  • the spout in addition to having an inclined flank imposing on it, during the manual display action, an axial reaction of release from the notch, also has a cross section of particular rounded shape communicating to it a slight radial elastic reaction movement under the effect of the manual rotation of the selector element.
  • This radial movement is obtained thanks to a certain degree of freedom provided in the articulation of the control lever on the selector element, as well as to the presence of a return spring which tends to bring this lever and its spout back into the initial position.
  • the device of document FR-A-2 561 421 is characterized by a special starting cam, a control member mounted on a spring and a particular machining of the selection cam. This device is therefore expensive and unreliable, due to its complexity.
  • the present invention relates to a device of the type mentioned above, characterized in that the starting means are formed in the internal wall parallel to the operating axis of the cam assembly, and that the member control comprises at least one rigid arm associated with a flexible element which are elastically connected to a hub mounted free in translation on the operating axis and inclined relative to this axis between the selector element and the hub.
  • control member comprises several pairs each consisting of a rigid arm and a flexible arm, extending through openings formed in the selector element, the free ends of the rigid arms are provided with probing ramps arranged to cooperate with starting notches formed in the axial internal wall of the cam assembly, and the rigid and flexible arms are connected in pairs to the hub by a flexible and elastic zone thin.
  • a washing machine programmer is essentially characterized by a program cam block 9, driven step by step, in a known manner by a geared motor unit and a pawl, not shown in the figures. Furthermore, a second motor, the pinion of which meshes, by means of a freewheel type device, with a toothed ring of the cam block is supplied through a double movable contact 7. It is this contact which controls either one or the other of these motors at the time of the manual selection of a program obtained by the rotation of the axis 1, protruding from the front face 10 of the programmer.
  • This axis is integral with the selector element 2 which also serves for centering the cam block 9.
  • the control member 3 is freely centered by its hub 35 on the axis 1.
  • This control member has several pairs of arms (32.31; 33.31; 34.31) in a star shape, for example three, which passing through lights provided in the selector element 2 can be housed in corresponding notches made (91,92) on the internal part in parallel to axis 1, of the cam block 9.
  • the connection of each arm with the hub 35 is ensured by an area 36 of small thickness. This connection allows axial flexibility, or elasticity, of the arms relative to the hub but no radial flexibility.
  • the hub 35 is, by construction, offset outside the plane defined by the ends of the arms in position in the notches of the cam block, and the arms therefore extend between the selector element 2 and the hub 35.
  • the direction of this offset is provided so that when a force is applied to the arms, the hub 35 slides on the axis 1 in the direction of the arrow F1 represented in FIG. 2.
  • Each arm inclined with respect to the axis 1 is constituted by a pair of two elements, a rigid element 34, 33, 32, provided with a feeler ramp 38 and a flexible inversion element, in the form of a radial arm 31.
  • Each ramp 38 of a rigid element cooperates with a starting ramp 91 of the cam block and each flexible element cooperates with a sudden fall reversal notch 92.
  • each of the rigid elements 32, 33, 34 has a different width, associated with a corresponding width of the notches provided in the cam block 9, and the flexible elements 31 of the three pairs of elements are angularly spaced, from their associated rigid elements 32, 33, 34, of different widths, so as to obtain only a possibility of operation over 360 °.
  • This device enables programmers of automatic washing machines having a display with manual preselection for the choice of programs, which is reliable and inexpensive.
