Definitions

  • the present invention relates to dishwashers and in particular a stall device for a dish rack mounted in a washing tub of a dishwasher.
  • dishwashers comprise a washing tub having at least one dish rack mounted in translation to guide means. These guide means allow the user to pull the basket to fill or empty for example and then to get inside the tank of the dishwasher.
  • the dish rack can move along the guide means and thus occupy an extracted position and a retracted position.
  • hooking means of the dish rack on its guide means are provided.
  • the user may nevertheless want to separate the dish rack from the guide means that support it to transport it to another place; this is the case for example if he wants to store his clean dishes at the end of the wash cycle.
  • the documents FR 2 958 145 and EP 2 371 260 describe guide rails in translation of at least one dish rack in a washing tub and arranged on both sides of the dish rack.
  • Each of the guide rails may comprise two rods mounted parallel to one below the other; an upper rod slidably mounted on a slide and a lower rod mounted to the dish rack.
  • a hook engaging with each guide rail holds the dish rack integral with the guide rails.
  • the stall of the dish rack rails often requires complicated handling for the user, not allowing a secure and simple separation of the dish rack.
  • the dish rack In the case of using the parallel mounted rods one below the other, the dish rack must be further tilted during the removal operation of the dish rack from the wash tub. The user can not remove the dishware basket filled with dishes to unload elsewhere for example.
  • the present invention aims to solve at least one of the aforementioned drawbacks.
  • the present invention relates to a washing tub of a dishwasher comprising two guide rails parallel to each other of a dish rack, said dish rack being mounted in translation between a retracted position and a position extracted from the wash tub, said dish rack having a first edge adapted to slide on a first of said two guide rails between said retracted position and said extracted position.
  • the first guide rail comprises a stop, said first edge of said dish rack being provided with an unhooking device comprising a holding portion and an unlocking lever.
  • the holding portion is integral with said dish rack and is adapted to abut against the abutment of the first guide rail.
  • the unlocking lever is pivotally mounted on the first edge of the dish rack and is adapted to act on the holding portion to disengage the holding portion from the position abutting against the stop of the first guide rail.
  • the stall device thus developed makes it possible to make the detachable dish rack simple and secure.
  • the unlocking lever allows for simple pivoting on the first edge of the dish rack to disengage the dish rack from the guide rail.
  • the holding portion being in the abutment position against the abutment of the first guide rail, this keeps the dish rack integral with the first guide rail until the user has decided to win.
  • the stall device thus developed is secure since the dish rack can not be unhooked from the guide rail unintentionally.
  • the holding portion comprises a cooperation wing having a protruding portion, the protruding portion being adapted to abut against the abutment of the first guide rail, the unlocking lever being adapted to act on the cooperation wing to disengage the projecting portion from the abutment position against the abutment of the first guide rail.
  • the unlocking lever comprises on either side of a pivot axis a pusher and a lifting head, the lifting head of the unlocking lever being adapted to cooperate with the cooperation wing.
  • the holding portion comprises a flexible portion extending the cooperation wing, the flexible portion being adapted to deform in order to disengage the projecting portion of the cooperation wing from the abutment position against the abutment of the first guide rail.
  • the flexibility of the flexible portion allows elastic deformation under the action of the unlocking lever. This makes it easy to disengage the protruding portion from the position in abutment against the abutment of the first guide rail.
  • the dish rack comprises on the first edge a shoulder, the shoulder being adapted to stop the pivoting of the pusher of the unlocking lever.
  • the shoulder avoids excessive pivoting of the pusher and thus prevent the risk of damage to the stall device. Indeed, this avoids for example the breaking of the unlocking lever following a strong support on the pusher.
  • the holding portion forms a single piece with the dish rack.
  • the dish rack comprises a basket holder and a dish tray, the basket holder being disposed at the periphery of said dish tray, the dish tray being adapted to receive the dishes to be washed.
  • the holding portion and the basket support form a single piece.
  • the single piece is made of plastic, for example molded or injected.
  • the plastic material makes it possible to easily manufacture the single piece and to give it the desired shape.
  • the dish rack comprising a second edge adapted to slide on a second of said two guide rails.
  • the first edge and the second edge of the dish rack are respectively provided with two stall devices.
  • the use of two unlocking devices on both sides of the dish rack makes it possible to remove the dish rack without having to tilt it. Indeed, once the two holding portions disengaged from the abutment position against the stops of the two guide rails by means of the two unlocking levers, the user can remove the dish rack by simple translation along the guide rails. . The dish rack is then kept horizontal during the operation of detaching the guide rails.
  • the user can thus if he wishes, load or unload the dish rack elsewhere before mounting it again in the washing tub. Indeed, since the dish rack is not inclined, the dish rack can be handled while being filled with dishes.
  • the washing tub comprises a front opening and said at least two guide rails respectively comprise a first guide segment having a first proximal end and a second guide segment having a second proximal end, the distance separating the first proximal end of the front opening being smaller than the distance separating the second proximal end of the front opening.
  • the offset between the first proximal end of the first guide segment and the second proximal end of the second guide segment makes it easier to mount the dish rack to the guide rails.
  • this offset facilitates the formation of the stop of the guide rail by allowing the passage of a tool to fold the first guide segment and form the stop.
  • the figure 1 represents a washing tub 1 according to one embodiment.
  • the washing tank 1 comprises a bottom wall 10 and side walls 11 on either side of the bottom wall 10.
  • An arch portion 12 is attached to the bottom wall 10 and the side walls 11 and defines an upper wall of the washing tub 1.
  • the bottom wall 10 and the side walls 11 define a front opening 13 of the washing tub 1.
  • the guide rails 2, 2' are parallel to one another.
  • Each dish basket 3, 4 is mounted in translation inside the washing tub 1.
  • Each dish basket 3, 4 is mounted on a first guide rail 2 and a second guide rail 2 '.

  • the dish baskets 3, 4 are fully inserted inside the washing tub 1.
  • the dish baskets 3, 4 are in the retracted position.
  • the dish baskets 3, 4 are suitable for receiving dishes, for example cutlery, to be washed.
  • dish baskets and guide rails and their arrangements in the washing tub 1 may vary.
  • washing tub 1 is described in a position equivalent to that in which the dishwasher will be used. In other words, it is considered that the washing tub 1 is placed so that the dish baskets 3, 4 extend in horizontal planes.
  • a vertical plane indicates a plane perpendicular to the horizontal planes and parallel to the side walls 11.
  • the figure 2 illustrates the dish baskets 3, 4 in the extracted position.
  • the extracted position corresponds to the position in which the dish rack is entirely outside the wash tub but is still mounted to the guide rails.

  • FIG. figure 3 An enlarged view of the stall device 5 of the first edge 42 of the dish rack 4 is shown in FIG. figure 3 .
  • two holding portions 6 are respectively formed in the first edge 42 and the second edge 43 of the dish rack 4.
  • the holding portions 6 are respectively integral with the first edge 42 and second edge 43 of the dish rack 4.
  • the two holding portions 6 cooperate respectively with two unlocking levers 7.
  • the holding portions 6 are here formed in the basket support 40.
  • the basket support 40 and the two holding portions 6 form a single piece.
  • the single piece can be made of any suitable material, for example molded or injected plastic.
  • a shoulder 45 is formed on each of the first edge 42 and the second edge 43.
  • stall device 5 which is provided with the first edge 42 of the dish rack 4 but remains of course valid for the other stalling devices of the washing tub 1.
  • the figure 4 illustrates an exploded view of the stall device 5 according to the embodiment of the figure 3 .
  • the holding portion 6 comprises a flexible portion 61 extending a cooperation wing 62.
  • the unlocking lever 7 is pivotally mounted on the first edge 42 of the dish rack 4.
  • the unlocking lever 7 comprises a pusher 71 and a lifting head 73.
  • the pusher 71 and the lifting head 73 are arranged on either side of a pivot axis 72.
  • the pivot axis 72 is perpendicular to the direction of the first guide rail 2.
  • the dish rack 4 comprises, on the first edge 42, hooks 44 adapted to receive the pivot axis 72 of the unlocking lever 7.
  • the unlocking lever thus constitutes an insert mounted to the holding portion 6 at the hooks 44.
  • the hooks 44 make it possible to hold in place the pivot axis 72 of the unlocking lever 7.
  • the unlocking lever 7 comprises a cooperating end 732 at the lifting head 73 and an actuating end 711 at the pusher 71.
  • the engagement flange 62 of the holding portion is formed so as to be insertable into the lifting head 73.
  • the lifting head 73 comprises projecting elements 731 adapted to receive the engagement wing 62.
  • the engagement flange 62 of the holding portion comprises a projecting portion of a main portion 621.
  • the main part 621 has a shape complementary to the lifting head 73.
