Definitions

  • the present invention relates to a household appliance with a pivoting door, permanently returned to its half-open position.
  • a large number of household appliances such as dishwashers, stoves, electric ovens, are fitted with pivoting doors. These doors open frequently on the front of these devices and can take, independently of any blocking device, three stable positions: a closed position, an open position and a half-open position.
  • the present invention intended to avoid these drawbacks, makes it possible to produce an improved and economical household appliance provided with a pivoting door, permanently returned to its half-open position: which allows this door to be automatically recalled in its opening position after unlocking its closing device.
  • a household appliance in accordance with US-A-3 450 125, comprising a frame and a pivoting door about an axis secured to the frame and permanently returned to its half-open position by a return spring biased in extension, the one of the ends is fixed to this pivoting door and the other to one end of a part articulated around an axis integral with the chassis of the apparatus, is characterized, according to the invention, in that the articulated part is a lever, pivoting in its central zone around the axis and that it includes a stop integral with the chassis, creating with the cooperation of the second free end of this lever a limitation of its rotation and for any position of the door between its closed position and its half-open position, a tension of the spring tending to return this door to this half-open position which is the equilibrium position of the door, the distance between the axis of rotation of the door and the end of the spring attached to the door then being the shortest.
  • fig. 1 shows a schematic view of a household appliance according to the invention, with a pivoting door permanently returned to its half-open position;
  • figs 2 to 4 show schematic partial views of the apparatus of fig. 1 showing the door thereof in the closed, ajar and open position respectively;
  • fig. 5 shows a partial schematic view of the apparatus of FIG. 1 with a closed door and a diagram showing the different degrees of tension of the return spring when this door occupies different positions.
  • the household appliance illustrated in fig. 1 comprises an envelope or chassis 1, a door 2 opening towards the front.
  • the door 2 is provided with arms 10 which allow it to pivot around an axis 15, fixed relative to the frame 1.
  • the device comprises at least one return spring 3, a pivoting lever 6 and a stop 14 which make it possible to permanently return the door 2 to its half-open position.
  • the lever 6 has the shape of an L with unequal branches 7 and 8 and can pivot around an axis 13 fixed relative to the frame 1 and located in the area where its branches 7 and 8 meet.
  • the rotation of the lever 6 in the opposite direction of the arrow 9 is limited by a stop 14 integral with the chassis 1.
  • the stop 14 is constituted by the wall of the chassis 1.
  • the spring 3 is attached on one side at a point 4 of the door 2 and on the other side at one end 5 of the branch 8 of the L-shaped lever 6.
  • the arm 10, by the surface of its end 11 which abuts against a bearing surface 12 limit the degree of opening of door 2 to the horizontal position.
  • the pivoting lever 6 can also have a shape other than that in L, for example a rectilinear, curvilinear, zigzag, in other words angular, shape.
  • the stop 14 can have any other shape and constituted by another part of the device.
  • door 2 When the closing device (not shown) of door 2 is unlocked, manually or automatically, for example under the control of a programmer, door 2 then pivots around the axis 15 to its equilibrium position which corresponds to a length of the spring 3 not tensioned. This equilibrium position is taken as the half-open position of door 2.
  • Fig. 5 shows this equilibrium position of the door at 17.
  • the attachment point 4 of the spring 3 passes from the position 16 or position of the closed door to the equilibrium position 17.
  • This point 4 describes the circle 18 which has for center the pivot axis 15 of the door 2.
  • a circle 19 is drawn which has the pivot axis 13 of the lever 6 as its center and the branch 8 of the lever 6 as its radius and the length of the spring 3 which is not tensioned in position 17 of the door 2.
  • spring 3 has only a minimum length when the axis 15, the end 5 of the lever 6 and the attachment point 4 of the spring are aligned, that is to say when the point 4 is at 17.
  • the lever 6 has not yet pivoted in the direction of the arrow 9, but the end of the branch 7 exerts zero pressure on the stop 14. If the door 2 is moved slightly apart on either side from its equilibrium position 17, the spring 3 lengthens by a length equal to the spacing between the circles 18, 19 and tends to bring the door 2 back into this equilibrium position 17.
  • the lever 6 pivots around the axis 13 and the spring 3 is extended so as to create a moment of return towards the equilibrium position 17.
  • the self-weight of door 2 creates a moment which opposes that of spring 3 and which, from a certain opening angle of door 2, becomes greater than the moment created by the spring 3.
  • the spring 3 always lengthens and creates a moment of return towards the position of equilibrium 17 always larger, which partially compensates for the moment, also increasing , the weight of door 2. This allows progressive opening of door 2.
