Definitions

  • the invention relates to a household appliance, in particular a refrigerator or freezer, with a housing which is equipped with a hinge element, wherein the hinge element has a mounting portion for mounting on the body of the household appliance, a projecting from the mounting portion support arm and a arranged at the free end of the support arm bearing element having.
  • Simple hinges used for the suspension of a household appliance door generally have a hinge pin which engages from above or below in a bearing sleeve of the door, thus defining a pivot axis of the door, and an arm, via which the hinge pin is firmly connected to the body. This arm is visible from the outside, which is distracting.
  • the WO 2007/031416 A1 discloses a housing for a household appliance with a hinge, which is arranged adjacent to a side surface of the body and body and door connects.
  • the door has a receiving space facing the carcass.
