Abstract
A heated surface and method of making the same is disclosed. The surface has a base. A first ceramic insulating layer is provided above the base. A heating element is provided above the first ceramic insulating layer. A second ceramic insulating layer is provided above the heating element. A protective layer is provided above the second ceramic insulating layer.
Claims20
A method of manufacturing a heated surface, comprising steps of:
- applying a first ceramic thermally insulating layer over a base surface to create a ceramic covered base surface;
- enclosing a heating element in a paper to form a paper-enclosed heating element, wherein the heating element is a flexible heating element;
- enclosing the paper-enclosed heating element in a plastic to create a plastic-enclosed paper-enclosed heating element;
- placing the plastic-enclosed paper-enclosed heating element on the ceramic covered base surface;
- applying a first protective layer over the plastic-enclosed paper-enclosed heating element;
- applying a second ceramic thermally insulating layer over the first protective layer that extends over the plastic-enclosed paper-enclosed heating element, wherein the first ceramic thermally insulating layer is a greater thermal insulator than the second ceramic thermally insulating layer;
- applying a second protective layer over the second ceramic thermally insulating layer which extends over the heating element.

A method of manufacturing a heated surface, comprising steps of:
- applying a first ceramic insulating layer over a base surface to form a ceramic covered base surface, the first ceramic insulating layer is applied as a flowable liquid;
- enclosing a heating element in a paper to form a paper enclosed heating element, wherein the heating element is an elongated flexible heating element;
- laminating the paper enclosed heating element to enclose the paper enclosed heating element in a protective plastic to create a laminated paper-enclosed heating element;
- applying an adhesive to the laminated paper-enclosed heating element or the ceramic covered base surface;
- placing the laminated paper-enclosed heating element on the ceramic covered base surface;
- applying a first protective layer over the laminated paper-enclosed heating element, the protective layer is applied as a flowable liquid and allowed to dry;
- applying a second ceramic insulating layer over at least a portion of the first protective layer which extends over the laminated paper-enclosed heating element, wherein the second ceramic insulating layer is thinner than the first ceramic insulating layer;
- and,
- applying a second protective layer over the second ceramic insulating layer.
