Definitions

  • refrigerators such as refrigerators or freezers
  • a double-walled door with an outer and inner wall, between which a cavity filled with insulating foam material is formed.
  • the outer wall is often formed by a door panel, which is bent at the sides in the direction of the inner wall.
  • a connector or door closure strip e.g. is designed as a plastic injection molded part.
  • Household appliances are also known in which the outer wall is higher than the inner wall, so that the closing part is at least partially concealed toward the visible side of the door by the outer wall.
  • connection piece is fixed by a positive connection to the outer wall.
  • this positive connection is characterized in that it is not visible from the outside, neither from the visible side of the door, nor from the inside of the door.
  • the positive connection is e.g. formed on a side facing the cavity of the connector.
  • the connecting piece is preferably concealed to a visible side of the door at least partially by the outer wall.
  • the invention is thus used in doors in which the outer wall is slightly longer, in particular higher, than the inner wall.
  • the connector then closes the cavity between the outer and inner walls and is thereby viewed from the visible side behind the outer wall. This leads to a uniform outside of the door.
  • the outer wall is preferably formed by a door panel, which e.g. is made of a metal sheet.
  • the inner wall is preferably made of plastic, as is the connector.
  • the connecting piece is designed as a plastic injection-molded part.
  • the positive connection is preferably a latching connection.
  • one of the connecting piece and outer wall has at least one latching hook, and the other at least one latching surface or latching edge.
  • the latching hook engages behind the latching surface or latching edge and thereby produces a latching connection.
  • the connector also by a positive connection or combinations of a positive and a non-positive, eg frictionally engaged, connection, or be secured by combinations of a form-fitting and a material connection to the outer wall.
  • the latching hook or the latching surface or latching edge are preferably formed integrally with the connecting piece. This eliminates the need for additional parts to secure the connector to the outer wall.
  • the latching hook is preferably arranged elastically resiliently on the connecting piece or on the outer wall.
  • the resilient movement preferably runs at least partially parallel to the latching surface or latching edge on the respective other part, so that the latching hook can slide resiliently behind it when mounting the connecting piece.
  • the latching surface or latching edge is elastically resilient, preferably in turn in one direction at least partially parallel to the latching surface.
  • this allows easy installation of the connector.
  • the outer wall is bent over at least on one side to form an outer wall side portion toward the inner wall, wherein the connecting piece is fastened in a form-fitting manner to the at least one outer wall side portion.
  • the outer wall side portion then preferably at least partially obscures the short sides of the connector.
  • the outer wall is symmetrically bent inwards on both sides, in order to create a symmetrical door, which can be articulated both on the left and on the right of a body of the household appliance.
  • the outer wall is preferably bent with a relatively large radius of curvature towards the inner wall.
  • a latching hook formed on the connecting piece engages behind a latching edge formed on the outer wall side section.
  • This locking edge preferably extends over a substantial part of the length of the outer wall and is preferably formed by a first folded portion, which is bent inwardly from the outer wall side portion.
  • the first fold portion is preferably approximately parallel to the outer wall side portion and approximately transverse to the visible side the door.
  • the latching edge is preferably formed by an edge of the Abkantungsabites, which faces the visible side of the door. The connector is then placed on engagement from the inside of the door and moved in the direction of the outer wall until the latch hooks on the connector behind the edge of the first Abkantungsabitess.
  • the latching hook is arranged on a rib of the connecting piece.
  • the rib is preferably sufficiently thin to ensure an elastically resilient suspension of the latching hook.
  • it is arranged transversely to the latching edge or latching surface on the outer door.
  • the rib of a base plate of the connecting piece from the bottom and approximately parallel to the outer wall side portion, but arranged transversely to the visible side.
  • the rib is preferably fixed only on one side on the connecting piece to be resiliently pivotable.
  • the outer wall is bent on an end side of the door inwardly towards a second folded portion, wherein the second folded portion is received in a groove formed on the connecting piece.
  • a tongue and groove connection is created, which defines the connector in one direction on the outer wall, for example, so that it can not slip up and down.
  • the second bent portion is preferably folded from the upper end side of the outer wall.
  • the groove is located below an upper side of the connecting piece, so that in this way the upper end of the door is formed.
  • the invention is also directed to a household appliance which is equipped with a door according to the invention.
