Abstract

See full text

A rigid plastic twist lock drain funnel for conveying defrost water from the interior of the refrigerator cabinet, through the insulation space, to the exterior. A top portion of the funnel has a groove seating an O-ring, and a central portion has a pair of radially extending cam-shaped ears. During fabrication, the drain funnel is inserted from inside the refrigerator liner through an aperture having notches for receiving the ears, and then the funnel is twisted approximately 90.degree. to engage the ears as a cam lock. In such arrangement, the funnel is securely attached to the liner and the O-ring provides a seal therebetween so as to prevent subsequently injected foam insulation from leaking to the interior of the cabinet. To allow for misalignment between the linear and the outer case, the opposite end of the drain funnel passes through an oversized hole in the outer case of the refrigerator. A spongy gasket around the lower end of the funnel is compressed between a shoulder of the funnel and the outer case so as to provide a seal therebetween.
