Description

The present invention relates to a domestic refrigerator appliance and the support structure for a front electronic control panel.

Prior art

Domestic refrigerators are already known with an electronic control panel mounted in combination with a support structure on the sheet frame on the front face of the refrigerator, which extends over the whole width above the refrigerator door. Either of documents EP-A-759530 ( ES-2192211-T ) and DE-A-198040430 discloses a support structure and an electronic panel. These support structures comprise a portion of the front wall in the area of the ceiling of the sheet frame which is adapted to a panel carrying the electronic circuits, a supplementary plastic electronic casing piece provided with a housing for the electric wiring guided to the interior of the ceiling of the refrigerator, and means for connecting the electronic panel to the sheet front wall.
The known control panel supports do not resolve as the invention does it, an integrated combination of the electronic panel with a support structure extending over the whole width of the frame, including the upper and front sheet walls of the ceiling of the refrigerator frame, as well as the two sheet lateral panels.

Disclosure of the invention

The object of the invention is an electronic control panel and a support structure on the frame of the refrigerator for the installation of the electronic panel, which is extended over the whole width of the ceiling and integrates the means for its attachment to the sheet frame of the appliance and for the connection of the control panel to the removable frame.
The advantage offered by the control panel support structure according to the invention, is the integration of the electronic control panel in the sheet frame of the refrigerator appliance, including the door swivelling hinges, being a common support structure of entire pieces over the whole width of the frame of the appliance, and also making a direct-acting connection of the electronic panel, so being it removable from the support structure. This aim is achieved by means of an intermediate moulded plastic adapter plate, which is connected between the front wall and both sheet lateral panels and which is provided with a series of securing noses also acting as an end-stop means against the sheet front wall. In addition, the electronic control panel is connected in a single direct-acting connection operation onto the adapter plate by means of elastic connection lugs.
The support structure of this electronic panel provides a support for the attachment of a door hinge, which is screwed directly onto the support structure, the latter being adapted with support means for two different types of hinge, one front and the other ceiling-mounted on either side of the appliance, for the respective installation of two doors of a different height.
