Patent 7731806 was granted and assigned to Illinois Tool Works on June, 2010 by the United States Patent and Trademark Office.
Automatic sealing of a dishwasher door is obtained through an electric actuator that moves the door from a close position adjacent to the opening of the washing chamber to a seal position in which the washing chamber is sealed typically against a gasket or the like. The actuator eliminates the need for the user to provide the force necessary to seal the gasket and/or can be used for improved venting of the washing chamber.
