Abstract

A clothes dryer with a first bulkhead having an access opening and a first edge defining a front opening confronting the access opening. The clothes dryer has a composite seal located between the first bulkhead and the first edge which has a foam layer comprising memory foam and a low-friction layer having a coefficient of kinetic friction less than 0.3, with the low friction layer confronting the first edge.

First claim

What is claimed is:

1. A clothes dryer comprising:
a cabinet defining an interior and having a first bulkhead at least partially defining an access opening to the interior;
a rotating drum having a first edge defining a first drum opening; and
a composite seal located between the first bulkhead and the first edge, the composite seal receiving the first edge and having a foam layer comprising memory foam and confronting the first bulkhead and a low-friction layer having a coefficient of kinetic friction less than 0.3, with the low-friction layer confronting and receiving the first edge.

2. The clothes dryer of claim 1 wherein the memory foam has a density in a 37-55 kg/m{circumflex over ( )}3 range.

3. The clothes dryer of claim 2 wherein the memory foam has a density of 40 kg/m{circumflex over ( )}3.

4. The clothes dryer of claim 2 wherein the memory foam has a compression resistance in a 1-4 kilopascal (kPa) range.

5. The clothes dryer of claim 4 wherein the memory foam has a compression resistance of 2 kPa.

6. The clothes dryer of claim 1 wherein the foam layer confronts the first bulkhead.

7. The clothes dryer of claim 6 wherein the foam layer is adhered to the first bulkhead.

8. The clothes dryer of claim 7 wherein the memory foam is a closed cell foam.

9. The clothes dryer of claim 4 wherein the foam layer is thicker than the low-friction layer.

10. The clothes dryer of claim 1 wherein the first bulkhead comprises a channel and the composite seal is located within the channel.

11. The clothes dryer of claim 10 wherein the channel circumscribes the access opening.

12. The clothes dryer of claim 11 wherein the first edge comprises a curl which extends into the channel.

13. The clothes dryer of claim 1 wherein the low-friction layer is heat sealed to the foam layer.

14. The clothes dryer of claim 1 wherein the foam layer is temperature resistant up to approximately 90 degrees C.

15. The clothes dryer of claim 1 further comprising a second foam layer having a first side bonded to the memory foam layer and a second side adhered to the first bulkhead.

16. A clothes dryer comprising:
a cabinet defining an interior and having a first bulkhead at least partially defining an access opening to the interior;
a rear bulkhead spaced from the first bulkhead;
an annular channel provided within at least one of the first and rear bulkheads;
a rotating cylindrical wall having at least one edge received within the annular channel; and
a composite seal located within annular channel and comprising a foam layer and a low-friction layer, the foam layer confronting the annular channel and the low-friction layer confronting the edge, wherein the foam layer is a low compression resistance memory foam.

17. The clothes dryer of claim 16 wherein the foam layer is adhered to the first bulkhead.

18. The clothes dryer of claim 17 wherein the memory foam has a density in a 37-55 kg/m{circumflex over ( )}3 range and a compression resistance in a 1-4 kilopascal (kPa) range.

19. The clothes dryer of claim 18 wherein the memory foam is a closed cell foam.

20. The clothes dryer of claim 16 wherein the foam layer is temperature resistant up to approximately 90 degrees C.
