Abstract:
1. A liquid dispenser comprising: a liquid supply channel; a liquid return channel; a liquid dispensing channel including a wall, the wall including a surface, a portion of the wall defining an outlet opening, the outlet opening including a length as viewed in a direction of a liquid flow through the liquid dispensing channel, the outlet opening including a width as viewed perpendicular to the direction of the liquid flow through the liquid dispensing channel, the length of the outlet opening being greater than the width of the outlet opening, the outlet opening including a downstream edge relative to the direction of the liquid flow through the liquid dispensing channel, the downstream edge being perpendicular to the surface of the wall of the liquid dispensing channel, the wall of the liquid dispensing channel also partially defining the liquid supply channel and the liquid return channel; a liquid supply that provides liquid that flows from the liquid supply channel through the liquid dispensing channel to the liquid return channel, the liquid flowing in the direction of the liquid flow through the liquid dispensing channel; and a diverter member that selectively diverts a portion of the liquid, flowing in the direction of the liquid flow, through the outlet opening of the liquid dispensing channel, wherein the diverter member is positioned spaced apart from the downstream edge of the outlet opening by a distance that is between a range of greater than or equal to 0.5× of the width of the liquid dispensing channel and less than or equal to 2.5× of the width of the liquid dispensing channel as viewed from a direction perpendicular to the surface of the wall of the liquid dispensing channel.
