An object of the present invention is to reduce the amount of solvent vapor floating around when a print head is cleaned in an inkjet recording device. In addition, an object is to reduce ink stains on a periphery of the print head. An inkjet recording device includes a main body portion and a print head. The main body portion includes an ink container that contains ink, and a solvent container that contains a solvent. The print head includes a nozzle connected to the ink container to discharge the pressurized and supplied ink, a charging electrode that charges ink particles discharged from the nozzle, a deflection electrode that deflects the ink particles charged by the charging electrode, and a gutter that collects the ink. In addition, a head mounting unit for cleaning the print head is provided. The head mounting unit is connected to a solvent vapor suction path for suctioning solvent vapor generated therearound.

Inkjet recording device

The present invention provides an inkjet recording device capable of automatically cleaning the head tip and a cleaning method for inkjet recording apparatus. An inkjet recording apparatus has a printhead that receives a supply of ink and prints, a main unit that supplies said ink to said printhead, and a cleaning unit that has a cleaning tank into which said entire printhead is inserted and injects a cleaning solution from a cleaning nozzle to said printhead for cleaning. The cleaning unit has a cleaning nozzle that sprays cleaning liquid into the cleaning tank and a cleaning base section that has a housing section that accommodates the tip of the printhead and allows said cleaning liquid to flow into the housing section. The cleaning liquid is allowed to flow into the housing section to clean the tip of the printhead.

Inkjet recording apparatus and method for cleaning inkjet recording apparatus

An ink jet recording apparatus includes an ink container in which ink to be used to perform printing on a print target is stored, a nozzle which is connected to the ink container and from which pressurized and supplied ink is jetted, charging electrodes that charge ink particles jetted from the nozzle with electricity, deflecting electrodes that polarize the ink particles charged with electricity by the charging electrodes, a gutter that recovers ink not used for printing, a solvent container in which a solvent is stored, and a liquid nozzle which is connected to the solvent container and from which a pressurized and supplied solvent is jetted. The liquid nozzle includes a liquid flow passage portion that extends from the nozzle in a direction of the gutter, and a liquid jet hole that is formed at an angle allowing the pressurized and supplied solvent to hit the nozzle through the liquid flow passage portion.
