Description

 Door with a door frame and a handle recess element and household refrigeration appliance with such a door

The invention relates to a door for a household refrigerator, with a door inner plate and a door outer plate, which are arranged on a multi-sided door frame produced.

Such a design of a door is known for example from DE 1 977 437 U. There, the door frame is completely circumferentially closed and the door panels are attached thereto. Doors for household refrigerators are also known in various configurations. Since they have a variety of components due to their design with regard to thermal insulation effect, a high number of variants is available, which must be made with different components. Especially with respect to the arrangement with a handle a variety of ways are given to arrange or form them on such a door. As a result of the construction, it is necessary for many doors to select a position for a handle which does not impair the thermal insulation effect, so that the handle is often placed on the outside. As a result, the structure of the door is increased in the depth direction and thus in thickness.

It is an object of the present invention to provide a door for a household refrigerator and such a household refrigerator, in which a compact construction of the door is achieved and a thermal insulation effect is maintained.

This object is achieved by a door and a household refrigerator according to the independent claims.

A door according to the invention for a household refrigerating appliance comprises a door inner panel and a door outer panel separate therefrom. The door inner panel and the door outer panel are spaced from each other. In addition, the door comprises a door frame which is separate from the door inner panel and the door outer panel. This door frame is generated in particular by bending and is designed multi-sided. This means that it extends to several sides of this quadrangular geometry with regard to the design of a quadrangular door. The door frame thus forms on the narrow side, the plate in the depth direction between the inner and the door outer plate forms, there arranged a component of the door.

An essential idea of the invention is to be seen in that the door frame is designed to be open in the circumferential direction of the frame shape. At a then formed in this direction of rotation open circulation section of the door frame a separate door handle recess element is arranged. By such a configuration, a very compact construction of the door can be achieved in particular in the depth direction. An especially designed specifically as a recessed grip handle is formed in this recessed grip element, in particular integrated. Since this recessed grip element is in turn arranged locally specifically, namely at this narrow side wall of the door and beyond then even locally exactly in this open circulation section, a very compact construction is achieved in the width direction of the door. In addition, at the same time provided by this recessed grip element quasi a lateral end part, which plate complements the door frame with respect to an outwardly covering a gap between the door inside and the door outside.
