6 Claims

1. A door hinge for use in household appliances, wherein the door hinge comprises a latch for mounting a door onto an appliance, a connecting link for connecting a hinge guide with the latch via a pivot point of the connecting link, a damper, a hinge body, a spring fit, a spring, and a pivot point of the latch;

wherein the latch is connected to the hinge body via the pivot point, wherein the damper is installed in the interior of the hinge guide located in the interior of the hinge body and movably connected to the hinge body, and wherein the damper comprises a damper fit surface and a damper head fit surface;

wherein the hinge body is provided with a damper stop for closing and a damper stop for opening, and wherein the hinge guide is provided with a damper stop for opening and a damper stop for closing;

wherein the damper stops are formed in such a way that, when moving the hinge from a closed position to an opened position and vice versa, free movement of the damper stops on the hinge guide past the damper stops on the hinge body is enabled;

characterised in that the hinge guide is dimensioned in such a way that a distance between the damper stop for opening and the damper stop for closing on the hinge guide is smaller than a distance of the maximum extension of the damper between the damper fit surface and the damper head fit surface when no force is acting on the damper, thereby enabling the damper fit surface and the damper head fit surface to always be in contact with two of the corresponding damper stops, namely, in the closed position the damper fit surface is in contact with the damper stop for closing on the hinge guide and the damper head fit surface is in contact with the damper stop for closing on the hinge body, in opened position the damper fit surface is in contact with the damper stop for opening on the hinge body and the damper head fit surface is in contact with the damper stop for opening on the hinge guide, and in a neutral area of functioning of the hinge, the damper fit surface is constantly in contact with the damper stop for closing on the hinge guide and the damper head fit surface is constantly in contact with the damper stop for opening on the hinge guide; and

whereby the damper in the initial position constantly applies force to increase the distance between the damper fit surface and the damper head fit surface, thereby enabling a controlled door closing and opening.
