Abstract

An exterior panel for a kitchen appliance includes a metallic substrate having a predetermined surface pattern on at least one side of the metallic substrate, wherein the metallic substrate is formed to include a predetermined contour. A coating layer is an organic paint coating composition on the at least one side of the metallic substrate, the coating layer including a predetermined color and a fingerprint resistive surface, wherein the coating layer is at least partially translucent such that the predetermined surface pattern is visible with the naked eye through the coating layer, and wherein the predetermined surface pattern is modified by the coating layer to reflect the combination of the predetermined surface pattern and the predetermined color of the coating layer.

First claim

The invention claimed is:

1 . An exterior panel for an appliance, the exterior panel comprising:
a metallic substrate having a surface pattern on at least one side of the metallic substrate, wherein the metallic substrate is formed to include a predetermined contour; and a coating layer being an organic paint coating composition on the at least one side of the metallic substrate, the coating layer including a selected color, wherein the coating layer is at least partially translucent such that the surface pattern is visible with a naked eye through the coating layer, and wherein the surface pattern is modified by the coating layer to reflect a combination of the surface pattern and the selected color of the coating layer.

2 . The exterior panel of claim 1 , wherein the predetermined contour includes a plurality of external sides that are connected at adjoining edges, and wherein the coating layer extends over each of the plurality of external sides and the adjoining edges, and wherein the coating layer is not capable of being physical vapor deposited onto the at least one side of the metallic substrate.

3 . The exterior panel of claim 1 , wherein the coating layer has a thickness of within a range of from approximately 0.2 mils to approximately 0.6 mils.

4 . The exterior panel of claim 1 , wherein the predetermined color of the coating layer is provided by a selected proportion of at least one additive disposed within the coating layer, wherein the selective proportion of the at least one additive is sufficient to allow the coating layer to be at least partially translucent, but not opaque.

5 . The exterior panel of claim 4 , wherein the at least one additive includes at least one of carbon black and tinted resin.

6 . The exterior panel of claim 1 , wherein the coating layer is a thermosetting polyester configured to be applied by a reverse rolling mechanism.

7 . The exterior panel of claim 1 , wherein the metallic substrate is stainless steel.

8 . The exterior panel of claim 1 , wherein the coating layer has a thickness of within a range of from approximately 0.25 mils to approximately 0.5 mils.

9 . The exterior panel of claim 4 , wherein the at least one additive is carbon black and the proportion of carbon black disposed within the coating layer is within a range of from approximately 0.1 percent by weight and approximately 1 percent by weight.

10 . A kitchen appliance comprising:
a metallic shaped outer metal panel including a surface texture defined on at least one side of the metallic shaped outer panel and disposed upon a kitchen appliance, wherein the metallic shaped outer panel is formed into a predetermined shape; and a tinted outer coating being a thermosetting polyester applied to the at least one side of the metallic shaped outer panel, the tinted outer coating having a thickness within a range of from approximately 0.2 mils to approximately 0.6 mils, wherein the tinted outer coating is at least partially translucent, wherein the surface texture is substantially visible through the tinted outer coating such that the surface texture is visible through the tinted outer coating when viewed with a naked eye, wherein the metallic shaped outer panel is configured to be formed into the predetermined shape after the tinted outer coating is applied to the at least one side of the metallic shaped outer panel.

11 . The kitchen appliance of claim 10 , wherein the metallic shaped outer panel is a stainless steel substrate that is one of grade 430 stainless steel and grade 201 stainless steel, and wherein the tinted outer coating is at least partially fingerprint resistant.

12 . The kitchen appliance of claim 10 , wherein the predetermined shape includes a plurality of external sides that are connected at adjoining edges, and wherein the tinted outer coating extends over each of the plurality of external sides and the adjoining edges, and wherein the tinted outer coating is not capable of being physical vapor deposited onto the at least one side of the metallic shaped outer panel.

13 . The kitchen appliance of claim 10 , wherein the tinted outer coating includes a predetermined additive, and wherein the predetermined additive includes at least one of carbon black and tinted resin.

14 . The kitchen appliance of claim 13 , wherein the predetermined additive is carbon black and a proportion of carbon black disposed within the tinted outer coating is within a range of from approximately 0.1 percent by weight and approximately 1 percent by weight.

15 . A tinted outer shell for an appliance comprising:
an appliance having a frame; a stainless steel substrate having a predetermined surface pattern defined within at least one side of the stainless steel substrate, and wherein the stainless steel substrate is one of grade 430 stainless steel and grade 201 stainless steel, wherein the stainless steel substrate is shaped in a predetermined contour and is applied to and supported by the frame of the appliance; and a coating layer, being an organic paint coating composition, disposed on the predetermined surface pattern, the coating layer including a thermosetting polyester and being at least partially transparent, wherein the coating layer includes a predetermined tint that filters a predetermined wavelength of visible light, thereby causing the predetermined surface pattern to visually define a tinted surface pattern having a different color than the predetermined surface pattern.

16 . The tinted outer shell of claim 15 , wherein the coating layer is not capable of being physical vapor deposited onto the at least one side of the stainless steel substrate.

17 . The tinted outer shell of claim 15 , wherein the coating layer has a thickness of within a range of approximately 0.2 mils to approximately 0.6 mils.

18 . The tinted outer shell of claim 15 , wherein the predetermined tint of the coating layer is provided by a predetermined proportion of a predetermined additive disposed within the coating layer, wherein the predetermined proportion of the predetermined additive is sufficient to allow the coating layer to be at least partially translucent, and wherein the predetermined additive includes at least one of carbon black and tinted resin.

19 . The tinted outer shell of claim 18 , wherein the predetermined additive is carbon black and a predetermined proportion of carbon black disposed within the coating layer is within a range of from approximately 0.1 percent by weight and approximately 1 percent by weight.

20 . The tinted outer shell of claim 15 , wherein the coating layer has a thickness of within a range of from approximately 0.25 mils to approximately 0.5 mils, and wherein the coating layer is configured to be applied by a reverse rolling mechanism.
