Abstract

A drier for commercial printers comprises an air receiving and discharging member having end walls, side walls, and a bottom wall and characterized by air receiving slots formed in the side walls and air discharging slots formed at the intersections between the side walls and the bottom wall. A lamp support frame having an imperforate top wall is positioned within the air receiving and discharging member. A fan support plate positions a fan above the top plate of the lamp frame for directing air onto the top plate thereof then downwardly along the side walls of the air receiving and discharging member and out through the air discharging slots thereof.

Dependent claims

A drier for commercial printers comprising:

an air receiving and directing member comprising opposed side walls interconnected by opposed end walls, the side walls and the end walls having aligned top and bottom edges;
a bottom wall extending inwardly from the bottom edges of the side walls and the end walls and having a rectangular light directing aperture formed therein and a plurality of tabs extending inwardly and upwardly relative to the light directing aperture;
the side walls each comprising a plurality of air discharging slots located at the intersections between the side walls and the bottom wall and having a plurality of air receiving slots formed therein at points located substantially midway between the top and bottom edges of the side walls;
a lamp support frame positioned between the side walls of the air receiving and directing member and in engagement with the bottom wall thereof;
the lamp support frame comprising a substantially imperforate top plate having a reflective surface formed on the underside thereof for reflecting infrared energy through the rectangular aperture of the air receiving and directing member;
a fan support plate mounted on the upper edges of the side walls of the air receiving and directing member and positioned above and in a spaced apart relationship with respect to the top plate of the lamp support frame and having at least one large air directing aperture extending therethrough;
at least one fan mounted on the fan support plate in alignment with the air directing aperture formed therethrough for directing air flow through the large aperture of the fan support plate and onto the upper surface of the top plate of the lamp support frame then outwardly toward the side walls of the air receiving and discharging member for discharge through the air discharge slots formed at the intersection between the side walls and the bottom wall of the air receiving and discharging member;
and
additional air entering the air receiving and discharging member through the slots formed in the side walls thereof for discharge through the air discharging slots together with the air received from the fan.
