Samsung patents refrigerator insulation with interlocking foam pieces
Samsung has filed a patent for a refrigerator design that uses multiple insulating foam pieces along the inner edges of the appliance. These pieces are shaped with specific protrusions and grooves that allow them to interlock, creating a tight seal between the inner storage area and the outer shell.
In the filing’s own words
A refrigerator comprises an inner case in which a storage compartment is inside; an outer case; and an insulating pad, including a plurality of insulating members along an edge of the inner case. At least one of the plurality of insulating members is arranged to contact with at least one other of the plurality of insulating members to form a contact surface. The contact surface comprises: a first contact portion extending from an inner surface of the insulating pad toward an outer surface of the insulating pad; a second contact portion extending from the outer surface of the insulating pad toward the inner surface of the insulating pad; and a third contact portion extending in a direction intersecting the first contact portion and the second contact portion such that the first contact portion and the second contact portion connect to each other.
What exactly they claim (claim 1)
1. A refrigerator comprising: an inner case in which a storage compartment is inside; an outer case on an outside of the inner case; and an insulating pad, between the inner case and the outer case, including a plurality of insulating members arranged along an edge of the inner case, wherein at least one of the plurality of insulating members is arranged to contact with at least one other of the plurality of insulating members so as to form a contact surface, wherein the contact surface comprises: a first contact portion extending from an inner surface of the insulating pad in a first direction toward an outer surface of the insulating pad; a second contact portion extending from the outer surface of the insulating pad in a second direction opposite the first direction and toward the inner surface of the insulating pad; and a third contact portion extending in a third direction intersecting the first contact portion and intersecting the second contact portion such that the first contact portion and the second contact portion connect to each other, wherein the third direction is both perpendicular to the first direction and perpendicular to the second direction.
