<P>PROBLEM TO BE SOLVED: To provide a cleaning device that can remove the dirt adhering to the inside of the nozzle and the dirt adhering to the liquid discharge surface without giving the stress to the liquid discharge surface, a liquid ejecting apparatus, and a method of cleaning an inkjet head. <P>SOLUTION: The laminar flow (16A) of a second liquid (16) that has the flow rate more than the maximum ejection speed of a first liquid (14) that is made to be ejected from the nozzle (12) of the inkjet head (10) is generated. The generated second liquid laminar flow is brought into contact with the first liquid inside the nozzle, and the circulation flow of the first liquid is generated inside the nozzle by the shear stress generated between the laminar flows of the first liquid and the second liquid inside the nozzle. While removing the dirts inside the nozzle, the dirt adhered to the liquid discharge surface is removed by making the generated laminar flow of the second liquid contact to the liquid discharge surface (12A) of the inkjet head. <P>COPYRIGHT: (C)2013,JPO&INPIT |
