发明名称 Dust management system in a table saw
摘要 A table saw includes a table top having an opening configured to receive a saw blade, and a motor positioned under the table top and configured to rotate the saw blade about an axis of rotation. The saw blade includes a midline that extends through the saw blade at the axis of rotation and is perpendicular with respect to the table top when the saw blade is perpendicular with respect to the table. A blade case is positioned under the table top that includes a blade chamber defined by a first wall on one side of the blade, a second wall on an opposite side of the blade, and a third wall along an outer perimeter of the blade chamber. At least one dust deflector positioned within the blade chamber between the axis of rotation and the third wall of the blade chamber that extends through the midline.

主权项 1. A table saw comprising: a housing defining an interior space; a table top positioned on the housing over the interior space and including an opening configured to receive a saw blade; a motor positioned under the table top within the interior space defined by the housing and configured to rotate the saw blade about an axis of rotation, wherein a midline that defines a front portion and a rear portion of the saw blade extends through the saw blade at the axis of rotation and is perpendicular with respect to the table top when the saw blade is perpendicular with respect to the table top; a blade case positioned under the table top within the interior space defined by the housing, the blade case including a lower wall, a front wall, a rear wall, a first side wall, and a second side wall that collectively define a blade chamber for surrounding at least a lower portion of the saw blade and having an opening in a lower, rear portion of the blade chamber, the lower wall extending forwardly from the opening below a lower edge portion of the saw blade, the front wall extending upwardly from the lower wall in front of a leading edge portion of the saw blade, the rear wall extending upwardly from the opening behind a trailing edge of the saw blade, the first side wall extending between the front wall, the rear wall and the lower wall on a first side of the saw blade, the second side wall extending between the front wall, the rear wall and the lower wall on a second side of the saw blade; and at least one dust deflector positioned within the blade chamber and extending between the first side wall and the second side wall substantially perpendicularly with respect to the saw blade, the at least one dust deflector including a lower deflector portion located between the axis of rotation and the lower wall of the blade case and an upper deflector portion located between the axis of rotation and the front wall of the blade case, wherein the lower deflector portion and the upper deflector portion are spaced apart from the lower wall and the front wall, respectively, of the blade case to form a dust channel that runs along the front wall and the lower wall to the opening, and wherein the at least one dust deflector defines an air gap through which the leading edge portion and the lower edge portion of the saw blade extend so that the leading edge portion and the lower edge portion of the saw blade are positioned in the dust channel when the saw blade is coupled to the motor.
