Abstract

An insulating glazed element composed of at least two glass sheets separated from each other by a small space in which a vacuum has been created is provided with a heating element on an internal face of at least one of the glass sheets. Two current supply collecting lines are positioned on at least part of the internal face of the at least one of said glass sheets. The heating element includes at least one conductive layer deposited on at least part of the internal face of the at least one of the glass sheets. The conductive layer extends between the two current supply collecting lines.

Claims

1. An insulating glazed element comprising:

two glass sheets of different sizes and separated from each other by mounts;

an inorganic seal about the periphery of the sheets so as to join the sheets together and to form a vacuum space between internal faces of the two glass sheets;

at least one heating element positioned on at least part of the internal face of at least one of said glass sheets; and

two current supply collecting lines on at least part of the internal face of the larger one of said glass sheets, wherein said collecting lines pass through said seal.

2. The insulating glazed element according to claim 1, wherein said at least one heating element comprises at least one conductive layer deposited on said at least part of the at least one internal face of the at least one of said glass sheets, wherein said at least one conductive layer extends between said two current supply collecting lines.

3. The insulating glazed element according to claim 2, wherein said conductive layer is a low-emissivity conductive layer based on a metal.

4. The insulating glazed element according to claim 2, wherein two internal faces of the said glazed element are coated with at least one conductive layer, and wherein at least some of the mounts are in contact with said layers and are made of electrically conductive materials.

7. The insulating glazed element according to claim 1, further comprising an electrical lead embedded in said seal.

8. The insulating glazed element according to claim 2, wherein said inorganic seal is electrically conductive and provided with two connectors.

9. The insulating glazed element according to claim 1, further comprising a conductive layer deposited around the periphery of at least one internal face of at least one of said glass sheets.

10. The insulating glazed element according to claim 2, wherein said conductive layer is a low-emissivity conductive layer based on a metal.

5. An insulating glazed element comprising:

two glass sheets of different sizes and separated from each other by mounts;

an inorganic seal about the periphery of the sheets so as to join the sheets together and to form a vacuum space between internal faces of the two glass sheets;

at least one beating element positioned on at least part of the internal face of at least one of said glass sheets; and

two current supply collecting lines on at least part of the internal face of the larger one of said glass sheets outside the vacuum space.

6. An insulating glazed element comprising:

two glass sheets of different sizes and separated from each other by mounts;

an inorganic seal about the periphery of the sheets so as to join the sheets together and to form a vacuum space between internal faces of the two glass sheets;

at least one heating element positioned on at least part of the internal face of at least one of said glass sheets;

two current supply collecting lines on at least part of the internal face of the larger one of said glass sheets;

two plugged holes passing through the smaller of said two glass sheets at locations facing the collecting lines, and a conductive material plugging the two plugged holes, said conductive material making electrical connection with the collecting lines.
