Definitions

  • the invention relates to a domestic appliance having a body and a hinged door by at least one hinge to the body, and having an opening limiting body, which has at least two sections, of which a first portion is held in an opening-limited position on the body and of the second section is fixed to the door.
  • the household appliance is preferably a refrigerator or freezer.
  • the doors of household appliances generally have only a limited opening angle.
  • a mechanism should be provided which defines an opening-limited position of the door and prevents the door from being opened further.
  • Such devices should also be able to absorb the kinetic energy of the door when it hits.
  • this is not fulfilled by the prior art opening limiting devices.
  • WO 2007/031469 A1 discloses a door for a household appliance with a door leaf and a hinge for hinging the door leaf to a body of the household appliance, wherein the hinge comprises a hinge pin and a hinge sleeve, which rotate into one another and of which one on the door leaf and the other is fixed to a support arm, which is intended to be fixed to the body.
  • the hinge has an opening limiting body, of which a first portion is fixed to the door leaf and from which a second portion abuts against the support arm in an opening-limited position of the door.
  • the opening-limiting body comprises a base plate from which the first and second portions protrude.
  • the opening limiting body of WO 2007/031469 A1 has the disadvantage that it is substantially resistant to bending, so that the door when striking in the opening-limited position hits very hard and can be damaged.
  • WO 2007/031425 A1 discloses a similar door but which has two different hinges.
  • the hinges each counteract pivoting movement of the door leaf beyond a maximum opening angle to counter torque.
  • the first hinge In an angular range immediately before reaching the maximum opening angle, the first hinge is freely rotatable, and the second exerts increasing counter-torque with increasing opening angle.
  • the second hinge has an elastically deformable buffer body with a cantilever arm which extends radially to the pivot axis, and in which a braking portion abuts from the side when the door approaches its maximum opening angle.
  • the construction of the hinge with the buffer body is very expensive.
  • the object of the invention is therefore to provide a household appliance in which the body and door are connected to each other by a hinge which is simple in construction but nevertheless capable of opening.
  • the opening limiting body is designed to convert at least part of the kinetic energy of the door into spring energy of the opening limiting body when the door is hit in the opening-limited position, the opening limiting body visibly deforming elastically.

  • the leg can bend elastically.
  • the opening limiting body has at least two resilient sections, which convert the kinetic energy into spring energy when the door is hit in the opening-limited position.
  • This may be two legs of the opening limiting body, which are bent elastically when striking the door in a similar or different manner.
  • the direction of the bending movement of the resilient portions preferably extends at least partially radially and / or parallel to the pivot axis.
  • the invention differs from conventional opening limiting bodies, in which the bending movement takes place in the circumferential direction, ie in the same direction as the braking force when the door stops.

  • the first portion and the leg may be the same length or different lengths.
  • the relative lengths of the first section and the leg determine the bending moments that act on the leg or on the first section. The longer a section, the greater the distance from the overlay, and the greater the bending moment.
  • the second portion is resilient and serves as a Befest Trentsab- section with which the opening limiting body is fixed to the door.
