The present invention relates to a door opening system for a domestic appliance (10) including at least one pivoting door (12). The door opening system comprises at least one door hinge (14) and at least one hook mechanism (16). The hook mechanism (16) includes a hook element (26) engaged or engageable with a recess (28) in a closed state of said door (12), so that the hook element (26) and the recess (28) form a snap-in mechanism. The hook element (26) is disengaged or disengageable from the recess (28) by operating a control element or said hook element (26). The door hinge (14) includes a stationary hinge part (18) and a pivoting hinge part (20). The stationary hinge part (18) is provided for a support structure of the domestic appliance (10), while the pivoting hinge part (20) is provided for the pivoting door (12). The stationary hinge part (18) is arranged or arrangeable horizontally inside or at the support structure of the domestic appliance (10). The stationary hinge part (18) comprises a first spring element (22) and a second spring element (24) provided for generating horizontal forces in the mounted state of the door hinge (14) at the domestic appliance (10). The first spring element (22) is provided for keeping the door (12) balanced within an outer opening angular range of said door (12). The second spring element (24) is provided for generating an opening force for the door (12) within an inner opening angular range, so that the door (12) is pushed into a partially opened state. The inner opening angular range extends between a closed state and the partially opened state of the door (12). The outer opening angular range extends between the partially opened state and a completely opened state of the door (12).
