an upper cap forming a top face of the door;
a lower cap forming a bottom face of the door;
an inner space defined by the outer panel, the inner panel, the upper cap and the lower cap;
a vacuum insulation assembly disposed in a part of the inner space, the vacuum insulation assembly comprising a vacuum insulation spaced apart from the front face, top face and bottom face of the door, and a first foam insulation provided with a mount portion allowing the vacuum insulation to be mounted thereto; and
a second foam insulation disposed in a remaining part of the inner space,
wherein the first foam insulation is formed by foaming and hardening an undiluted urethane foam solution in a first foam insulation forming mold; and
wherein the second foam insulation is formed by foaming and hardening a urethane foam solution in the remaining part of the inner space.
4. A refrigerator comprising:
a body;
a storage compartment arranged in the body such that a front face thereof is open; and
a door to open and close the front face of the storage compartment,
wherein the door comprises:
an outer panel having a front face;
an inner panel forming a rear face of the door;
an upper cap forming a top face of the door;
a lower cap forming a bottom face of the door;
an inner space defined by the outer panel, the inner panel, the upper cap and the lower cap;
a vacuum insulation assembly disposed in a part of the inner space, the vacuum insulation assembly comprising a vacuum insulation spaced apart from the front face, top face and bottom face of the door, and a first foam insulation provided with a mount portion allowing the vacuum insulation to be mounted thereto; and
a second foam insulation disposed in a remaining part of the inner space, and
wherein the outer panel, the inner panel, the upper cap, the lower cap, the first foam insulation and the vacuum insulation are fixed to each other by adhesiveness of the second foam insulation.
5. A refrigerator comprising:
a body;
a storage compartment arranged in the body such that a front face thereof is open; and
a door to open and close the front face of the storage compartment,
wherein the door comprises:
an outer panel having a front face;
an inner panel forming a rear face of the door;
an upper cap forming a top face of the door;
a lower cap forming a bottom face of the door;
an inner space defined by the outer panel, the inner panel, the upper cap and the lower cap;
a vacuum insulation assembly disposed in a part of the inner space, the vacuum insulation assembly comprising a vacuum insulation spaced apart from the front face, top face and bottom face of the door, and a first foam insulation provided with a mount portion allowing the vacuum insulation to be mounted thereto; and
a second foam insulation disposed in a remaining part of the inner space, and
wherein the first foam insulation is fitted between the upper cap and the lower cap to be temporarily fixed such that the first foam insulation is prevented from being shaken due to foaming pressure generated when the second foam insulation is being disposed in the remaining part of the inner space by foaming.
6. A refrigerator comprising:
a body;
a storage compartment arranged in the body such that a front face thereof is open; and
a door to open and close the front face of the storage compartment,
wherein the door comprises:
an outer panel having a front face;
an inner panel forming a rear face of the door;
an upper cap forming a top face of the door;
a lower cap forming a bottom face of the door;
an inner space defined by the outer panel, the inner panel, the upper cap and the lower cap;
a vacuum insulation assembly disposed in a part of the inner space, the vacuum insulation assembly comprising a vacuum insulation spaced apart from the front face, top face and bottom face of the door, and a first foam insulation provided with a mount portion allowing the vacuum insulation to be mounted thereto; and
a second foam insulation disposed in a remaining part of the inner space, and
wherein the first foam insulation is temporarily fixed to the outer panel by an adhesive member such that the first foam insulation is prevented from being shaken due to foaming pressure generated when the second foam insulation is being disposed in the remaining part of the inner space by foaming.
