Definitions

  • the aim is to facilitate the task of the housewife who, when she opens the body door, will thus automatically find the drum door in the correct position; thus it will no longer have to turn the drum by hand, this maneuver being sometimes painful when the machine is full of wet linen and presenting the risk of pinching your fingers.
  • the present invention aims to achieve a simple and reliable positioning device.
  • such a washing machine is remarkable in that the drum is held in position by means of a pad brake which, under the action of a radial force, comes to bear on said belt to brake and immobilize the drum by means of the pulley.
  • the device according to the invention is remarkable in that that said radial force is exerted on the pad brake by a braking spring previously bandaged in the armed position and then released by a trigger and a trigger, said trigger being actuated by said detection of the passage of the drum door in the position loading / unloading.
  • the washing machine includes a heat engine to band the said brake spring and, thus, arm the said trigger.
  • said detection is carried out by means, on the one hand, a lug placed on the pulley of the drum, -on the other hand of an electromagnet with plunger core fixed on the trigger, the said electromagnet being activated by the opening of the body door and arranged so that, in this case, its plunger core is driven by the said lug.
  • the detection device is also notably advantageous for the detection device to be dissociated from the braking device because the forces involved have different values.
  • the pulley POU for driving the drum includes an ERG lug suitably positioned with respect to the door of the drum, not shown.
  • the detection element is an ELAM electromagnet, the NOY plunger core of which comes radially in the path of the ERG lug when the electromagnet is activated.
  • the electromagnet is fixed on the trigger DET which is a mechanical part pivotally mounted around the trigger axis ADE; the position of the trigger is determined by an RDE trigger return spring and a stop not shown.
  • a PROD prominence of the trigger is in contact with the trigger GAC which is pivotally mounted around the axis of trigger AGA; the trigger has the function of retaining the EFR brake assembly in the armed position; to do this, the trigger includes a BEC spoiler on which the brake assembly bears under the effect of the brake spring RFR; the brake assembly is movable along the axis AFR which is directed radially towards the center CP of the pulley; on the side of the pulley, the brake assembly is provided with a PAT brake shoe which, under the action of the RFR spring, bears on the drive belt COU.
  • Figure 1 also includes the following: - an IGA trigger switch which cuts the current when the trigger leaves its armed position. - a CE electrical circuit which, when the body door is open, lets current flow to the IGA trigger switch to supply both the ELAM electromagnet and the MOT motor for driving the drum. - an MTH heat engine which, when powered, pushes with its movable finger DG (dashed in Figure 1) the EFR brake assembly by banding the RFR spring until the BEC spoiler of the trigger comes to block the brake assembly; the operation of the MTH motor is for example based on the expansion of a wax when it is heated. Such an engine is manufactured for example by the company ELTEK in Casale (Italy) under the reference 100281.
  • FIG. 2 the operating mode of the positioning device appears by comparison with FIG. 1, the two figures include the same elements with the same references, only the positions are different.
  • the MOT motor When the housewife opens the body door, the MOT motor is powered to rotate at relatively slow speed and in a direction such that the pulley rotates, as shown in the figure, clockwise; simultaneously the ELAM electromagnet is energized and the NOY plunger core is placed in the path of the ERG lug of the pulley.
  • the maintenance of the drum is only mechanical and positive, it is therefore preserved even if the washing machine is not no longer supplied with current.
  • the heat engine can be put into action to reset the system, either when the body door is closed during washing, or at the start of each closed door program; as soon as the heat engine ceases to be supplied with current, it cools down, the movable finger resumes its place, and the system is ready to operate again since the trigger and the trigger have resumed their places in FIG. 1 under the action of return springs.
  • the body door is provided with a safety switch, it is advantageous that this same switch also constitutes the means for detecting the opening of the body door.
  • FIG. 3 shows a variant arrangement of the trigger provided with its electromagnet which allows satisfactory operation for both directions of rotation: the axis of rotation of the trigger ADE is positioned on the same axis as the NOY core, and the trigger has two prominences PRODA and PRODB. So whatever the direction of rotation of the drum 51 or 52, the trigger always drives the trigger GAC in the direction of the arrow F.
