A manifold receives and distributes insulating foam to an interior of a consumer appliance case. The manifold includes an inlet attachable to a source of insulating foam exterior to the consumer appliance case, at least two outlets disposed at different locations within the consumer appliance case, an inlet passageway leading from the inlet further into the consumer appliance case interior, and at least two outlet passageways, each outlet passageway providing communication between the inlet passageway and a respective one of the outlets. Insulating foam received by the inlet is distributed to the interior of the consumer appliance case via the inlet passageway, outlet passageways and outlets. Related foamed-in case designs and methods of foaming-in a case are also disclosed.

1. A consumer appliance comprising: a consumer appliance case including an outer case and an inner liner, an interior of the consumer appliance case defined between the outer case and the inner liner;a rigid tubular manifold body mounted in the interior of the consumer appliance case having an inlet
1. A consumer appliance comprising: a consumer appliance case including an outer case and an inner liner, an interior of the consumer appliance case defined between the outer case and the inner liner;a rigid tubular manifold body mounted in the interior of the consumer appliance case having an inlet attachable to a source of insulating foam exterior to the consumer appliance case, at least two outlets disposed at different locations within the consumer appliance case, an inlet passageway leading from the inlet further into the interior of the consumer appliance case, an inlet passageway leading from the inlet further into the interior of the consumer appliance case, and at least two outlet passageways, each outlet passageway providing communication between the inlet passageway and a respective one of the outlets, whereby insulating foam received by the inlet is distributed to the interior of the consumer appliance case via the inlet passageway, outlet passages and outlets; andinsulating foam disposed within the consumer appliance case between the outer case and the inner liner, the foam surrounding the rigid tubular manifold body within the interior of the consumer appliance case. 2. The consumer appliance of claim 1, wherein the inlet passageway and the outlet passageways are tube shaped. 3. The consumer appliance of claim 1, wherein the rigid tubular manifold body includes at least four outlets and outlet passageways. 4. The consumer appliance of claim 1, wherein at least one distribution tube is attached to at least one of the outlets to distribute foam away from the rigid tubular manifold body. 5. The consumer appliance of claim 1, further comprising flow diverters located on at least one of the outer case or the inner liner of the consumer appliance case. 6. The consumer appliance of claim 1, wherein the rigid tubular manifold body comprises a plastic. 7. The consumer appliance of claim 6, wherein the rigid tubular manifold body comprises polyethylene. 8. A consumer appliance comprising: a case including an outer case and an inner liner;a foam distribution manifold mounted within the case between the outer case and the inner liner, the manifold having a rigid tubular manifold body with an inlet attachable to a source of insulating foam exterior to the case, at least two outlets disposed at different locations within the case, an inlet passageway leading from the inlet further into the case, and at least two outlet passageways, each outlet passageway providing communication between the inlet passageway and a respective one of the outlets; andinsulating foam disposed within the case between the outer case and inner liner, the foam surrounding the rigid tubular manifold body. 9. The consumer appliance of claim 8, wherein the inlet passageway and the outlet passageways are tube shaped. 10. The consumer appliance of claim 8, wherein the rigid tubular manifold body includes at least four outlets and outlet passageways. 11. The consumer appliance of claim 8, wherein at least one distribution tube is attached to at least one of the outlets to distribute foam away from the rigid tubular manifold body. 12. The consumer appliance of claim 8, further comprising flow diverters located on at least one of the outer case or the inner liner of the consumer appliance case. 13. The consumer appliance of claim 8, wherein the rigid tubular manifold body comprises a plastic. 14. The consumer appliance of claim 13, wherein the rigid tubular manifold body comprises polyethylene. 15. A method of forming a consumer appliance case comprising: attaching an outer case to an inner liner so as to leave a space therebetween;attaching a foam distribution manifold to one of the outer case or inner liner within the space, the manifold having a rigid tubular manifold body with an inlet attachable to a source of insulating foam exterior to the case, at least two outlets disposed at different locations within the case, an inlet passageway leading from the inlet further into the case, and at least two outlet passageways, each outlet passageway providing, communication between the inlet passageway and a respective one of the outlets; andproviding insulating foam to the space via the inlet, the inlet passageway, the outlet passageways and the outlets, the foam expanding within the space and at least partially surrounding the rigid tubular manifold body which remains in the space. 16. The method of claim 15, wherein the attaching step further includes attaching distribution tubes to at least one of the outlets to direct foam further from the rigid tubular manifold body. 17. The method of claim 15, wherein the rigid tubular manifold body includes at least four outlets and outlet passageways. 18. The method of claim 15, wherein the rigid tubular manifold body comprises a plastic. 19. The method of claim 15, wherein the rigid tubular manifold body comprises polyethylene.
