Multi-functional hinge device having a first connection means assigned to be fixed to a structure or frame of an appliance; and a second connection means, that is rotatable around its own hinge hub means, and assigned to be fixed to a door or hatch of the appliance to allow the opening and closing movements between the extreme closing and opening conditions of said door; in an operative condition, the rotation axis of said hub means is horizontal, and the plane of the door in the closed condition is vertical or nearly vertical; said device comprises at least: - a rocker arm means that is constrained, by means of a first pivot means parallel to the hub means, to the first connection means, so as to freely rotate around the axis of the first pivot means where such rocker arm means bears a second pivot means spaced from the first pivot means and parallel thereto; - a connecting rod means having an end that is linked to the rocker arm means by means of the second pivot means, so as to freely rotate around the axis of such second pivot means, and having the opposite end that is linked to the second connection means by means of a third pivot means, parallel to the hub means, so as to freely rotate around the axis of such third pivot means; - a slider means that is constrained to the first connection means by means of guide means (41, 42) for the sliding of the slider means towards the inside and the outside of the appliance and that bears the hub means at an outer end thereof; such slider means being linked to the rocker arm means whose rotation towards the closing condition causes the translation of the slider means towards the internal condition; - an elastic means having an end that is linked to the first connection means and the other end that is linked to the slider means; Where, in the operative door-balancing conditions of device 1, such elastic means acts on the slider means with an elastic force applied in the same direction as the closing direction; said device being characterized in that one of the ends of the elastic means is connected to the slider means by means of a flexible means engaged with a return pulley; the other end of the elastic means is fixed or hooked to a swinging arm means bearing a fourth pivot means for the rotatable connection with one end of a lever means, and the opposite end of which is rotatably connected with the connection means by means of a fifth pivot means parallel to the hub means. - a rocker arm means that is constrained, by means of a first pivot means parallel to the hub means, to the first connection means, so as to freely rotate around the axis of the first pivot means where such rocker arm means bears a second pivot means spaced from the first pivot means and parallel thereto; - a connecting rod means having an end that is linked to the rocker arm means by means of the second pivot means, so as to freely rotate around the axis of such second pivot means, and having the opposite end that is linked to the second connection means by means of a third pivot means, parallel to the hub means, so as to freely rotate around the axis of such third pivot means; - a slider means that is constrained to the first connection means by means of guide means (41, 42) for the sliding of the slider means towards the inside and the outside of the appliance and that bears the hub means at an outer end thereof; such slider means being linked to the rocker arm means whose rotation towards the closing condition causes the translation of the slider means towards the internal condition; - an elastic means having an end that is linked to the first connection means and the other end that is linked to the slider means;
