  • the one end portion is to be mounted on the body, the second end portion is rolled up at its free end into a sleeve.
  • the invention is therefore based on the object to provide a hinge element and a housing for a household appliance, which is easy to manufacture, in which a cable channel can be integrated into the hinge element, and which allows an even larger opening angle of the door.
  • This object is achieved in that at an above-mentioned hinge element at the free end of the support arm, two projecting in opposite directions bearing journals are arranged.
  • the two journals form a bearing element and replaced the rolled-up sleeve of the hinge element according to the prior art.
  • the two journals are aligned along a common pivot axis of the hinge.

  • the hinge element can be produced inexpensively and yet has a high strength.
  • the support arm has a curvature in a section perpendicular to the pivot axis.
  • a recess is formed, into which a side wall of a receiving space of the door engages when opening the door, whereby a large opening angle is allowed.
  • the curvature of the support arm is preferably designed such that an even larger opening angle is made possible than in WO 2007/031416 A1.
  • the hinge element is preferably adapted as far as possible to the pivoting movement of the side wall of the receiving space of the door.
  • the support arm is angled at an obtuse angle from the mounting portion to - together with the mounting portion - to span a semicircle along which the side wall is pivoted when opening the door.
  • the mounting portion and the adjacent thereto portion of the support arm are adapted as far as possible to a semicircular shape.

  • the support arm In the direction of the pivot axis, the support arm preferably has a lower height at its free end than the mounting portion. As a result, the available space is used optimally and created sufficient space for the protruding in opposite directions bearing pin.
  • the support arm tapers from the mounting portion toward its free end in the direction of the pivot axis at least on one side.
  • the forces are optimally distributed over the hinge element.
  • the support arm tapers from the mounting portion to its free end in the direction of the pivot axis on both sides.

  • the second portion 34 is additionally fastened by a screw 31.
  • a middle leg 33 of the opening limiting device Pers 30 extends along a relative to the pivot axis 3 obliquely aligned bearing surface 36, which is also formed in the bottom 37 of the connecting piece 7.
  • Fig. 9 shows how Fig. 6 is a perspective view of the upper right corner of the refrigerator 1, with hinged door.
  • the lower portion of the bearing bolt 20 is pivotally received in the bearing sleeve 23 of the bearing eye 24.
  • the first section 32 of the opening limiting body 30 engages behind the support arm 12 and is therefore hidden in FIG. 9.
  • the receiving space 8 is covered by a cover strip 43.
  • Fig. 9 shows a cable bundle 45, which is guided through the cable channel 21 in the bearing pin 20 in the cavity of the door 2.
  • FIG. 10 also shows a perspective view of the upper right corner of the refrigerator with hinged door, but without cable bundle 45 and with removed cover strip 43.

  • the opening limiting body 30 can be seen from above, as well as the trough 35, in which the second portion 34 is fixed. As can be seen from FIG. 11, the first section 32 of the opening limiting body 30 engages behind the support arm 12 and abuts there in the opening-limited position of the door in the area between the second section 14 and the end section 15. In this widely opened position, the side wall 28 of the receiving space 8 pivots into the recess of the support arm 12 formed by the curvature.
  • the sections 13, 14 and 15 of the support arm 12 are curved such that the side wall 28 does not abut the support arm 12 when opening the door, although it describes along the dotted line P an arc of up to 135 °.
  • the first portion 32 of the opening limiting body 30 is further arranged in a clearing 52 in the side wall 28, so that it engages behind the support arm 12 even with a large opening angle.
  • the curved portion 14 of the support arm 12 projects into the pocket 39, which is formed in the wall 38 of the connecting piece 7.
  • the pocket 39 it is possible to form the first section 13 particularly long and the curvature of the second section 14 particularly strong, which allows a particularly large opening angle of the door.
