Abstract:
1. An ink jet recording device comprising: a printing head comprising a nozzle that jets ink to form ink particles, an electrification electrode that electrifies ink particles to be used for printing among the ink particles formed by the nozzle, a deflection electrode that deflects a flying direction of the ink particles electrified by the electrification electrode, and a gutter that collects ink particles not used for printing among the ink particles formed by the nozzle; and a main body comprising an ink container which accumulates ink, an ink supply pump which supplies the ink from the ink container through an ink supply path to the nozzle, an ink recovery pump which return the ink collected by the gutter to the ink container through an ink recovery path, and an exhaust circulation path for discharging exhaust solvent vapor including solvent component generated in the ink container to the gutter; wherein the gutter comprises an ink flow path block having an ink inflow port, the ink flow path block through which the ink collected by the ink inflow port flows and an exhaust flow path block connected to the ink flow path block at a side of the ink recovery path from the ink inflow port; and wherein the exhaust circulation path is connected to the exhaust flow path block, the exhaust solvent vapor in the ink container is supplied into an exhaust path in the exhaust flow path block through the exhaust circulation path, the exhaust solvent vapor supplied into the exhaust path is supplied into an ink flow path in the ink flow path block and the exhaust solvent vapor supplied into the ink flow path is suctioned by the ink recovery pump to be supplied into the ink container through the ink recovery path, so that the exhaust solvent vapor generated in the ink container circulates in the gutter and the ink container.
