Abstract

An appliance control panel is described. The control panel is a laminate assembly of a front metal panel and a rear polymeric film. The film carries various electronic circuits and other components which are operable from the metal panel.

Claims

1. A control panel assembly comprising:

a generally planar metal panel defining a front face, an oppositely directed rear face, and at least one aperture;

a generally transparent polymeric film layer, defining a frontwardly directed face and a rearwardly directed face, the frontwardly directed face being mated to the rear face of the panel; and

a layer of an adhesive disposed between the rear face of the panel and the frontwardly directed face of the film layer for adhering the frontwardly directed face of the film layer to the rear face of the panel;

wherein the polymeric film layer includes at least one component disposed thereon, the component selected from the group consisting of an actuator, circuit, indicator, light, switch, processor, and combinations thereof;

wherein the aperture defined in the metal panel is aligned with the at least one component;

wherein the polymeric film defines at least one circuit and component disposed on the rearwardly directed face;

wherein the metal panel and the adhesive layer define first and second apertures, respectively, the first and second apertures aligned with one another, and the rearwardly directed face of the polymeric film having a decorative layer disposed thereon and visible from the front face of the metal panel through the first and second apertures.

2. The control panel assembly of claim 1 wherein the metal panel includes indicia on the front face.

3. The control panel assembly of claim 1 wherein the adhesive layer defines at least one aperture that is aligned with the at least one component.

4. The control panel assembly of claim 1 wherein the metal panel has a thickness of from about 0.005 inches to about 0.200 inches.

5. The control panel assembly of claim 1 wherein the metal panel is formed from steel or aluminum.

6. The control panel assembly of claim 1 wherein the polymeric film has a thickness of from about 3 mils to about 40 mils.

7. The control panel assembly of claim 1 wherein the polymeric film is formed from a material selected from the group consisting of polyethylene terephthalate, polycarbonate, blends thereof, and combinations thereof.

8. The control panel assembly of claim 1 wherein the polymeric film includes a hard coat layer.

9. The control panel assembly of claim 1 wherein the film layer includes at least one raised region.

10. The control panel assembly of claim 1 wherein the adhesive layer includes a pressure sensitive adhesive.

11. An appliance including the control panel assembly of claim 1.

12. The control panel assembly of claim 1 wherein the control panel does not include a rear support.

13. A control panel assembly consisting essentially of:

a generally planar metal panel defining a front face and an oppositely directed rear face;

a generally transparent polymeric film layer disposed on the rear face of the panel; and

a layer of an adhesive disposed between the panel and the film layer for adhering the film layer to the rear face of the panel;

wherein the polymeric film layer includes at least one component disposed thereon, the component selected from the group consisting of an actuator, circuit, indicator, light, switch, processor, and combinations thereof;

wherein the polymeric film defines a rearwardly directed face and the at least one component is disposed thereon;

wherein the metal panel and the adhesive layer define first and second apertures, respectively, the first and second apertures aligned with one another, and the rearwardly directed face of the polymeric film having a decorative layer disposed thereon, wherein the at least one component and the decorative layer are visible from the front face of the metal panel through the first and second apertures.
