A refrigerator comprising a hinge mechanism hingeably supporting and carrying the refrigerator door openable to allow access into the refrigerator, the hinge mechanism having a hinge housing placeable underneath an upper wall of the refrigerator and receiving a hinging means inside the hinge housing in a fixed manner such that the hinging means mechanically communicates with the refrigerator door when effectuating opening and closing of the door, wherein - the hinge housing defines an inner space with a pair of oppositely disposed engagement housings receiving springs, each spring being in connection with a first and second fixation rod (15, 16) linked to each other by means of a rotation portion at two ends of which the first and second fixation rod (15, 16) are attached, the rotation portion being centrally rotatable to displace the first and second fixation rod (15, 16) whereby advancement of the hinging means into the hinge housing in a mounting direction provides movement of the first and second fixation rod (15, 16) in a simultaneous and symmetrical manner together with rotational movement of the rotation portion, the refrigerator being characterised in that - the hinging means comprises a hinging support body in the form of a substantially flat body insertable into the hinge housing underneath the first and second fixation rods (15, 16), - the first and second fixation rods (15, 16) are respectively in connection with a contact portion communicating with the hinging support body of the hinging means in the manner that advancement of the hinging support body in the mounting direction moves the first and second fixation rods (15, 16) further in the engagement housings, - the hinging support body of the hinging means introduced into the hinge housing is removable by rotational movement of the rotation portion simultaneously symmetrically moving the first and second fixation rod (15, 16) - the hinging means is locked inside the hinge housing by the contact portions which are respectively biased by the springs to be moved in a direction perpendicular to the mounting direction of the hinging means. - the hinge housing defines an inner space with a pair of oppositely disposed engagement housings receiving springs, each spring being in connection with a first and second fixation rod (15, 16) linked to each other by means of a rotation portion at two ends of which the first and second fixation rod (15, 16) are attached, the rotation portion being centrally rotatable to displace the first and second fixation rod (15, 16) whereby advancement of the hinging means into the hinge housing in a mounting direction provides movement of the first and second fixation rod (15, 16) in a simultaneous and symmetrical manner together with rotational movement of the rotation portion, the refrigerator being characterised in that - the hinging means comprises a hinging support body in the form of a substantially flat body insertable into the hinge housing underneath the first and second fixation rods (15, 16), - the first and second fixation rods (15, 16) are respectively in connection with a contact portion communicating with the hinging support body of the hinging means in the manner that advancement of the hinging support body in the mounting direction moves the first and second fixation rods (15, 16) further in the engagement housings, - the hinging support body of the hinging means introduced into the hinge housing is removable by rotational movement of the rotation portion simultaneously symmetrically moving the first and second fixation rod (15, 16) - the hinging means is locked inside the hinge housing by the contact portions which are respectively biased by the springs to be moved in a direction perpendicular to the mounting direction of the hinging means.
