Abstract:

Until this time, the problem of ice and snow buildup on windshields has been dealt with using a technology that was developed to remove water from the exterior and condensation from the interior. Ice and frost removal from the outside of a windshield using the defrost system required an extensive warm-up period combined with the manual operation of an ice scraping device. This method is impractical when the vehicle is moving. Attempts to melt ice and snow on the rear window using electric resistance wires embedded in the glass work well, but cannot be used in front facing applications because of interference with vision caused by the wires. The forced hot air approach proposed in this invention allows the glass to remain clear, and aids the windshield wipers in removing the softened and/or melted snow, a job for which the wipers were designed.
