Electrochemical machine capable of removing electrolytic product

An electrochemical machine comprising:

• a processing tub filled with an electrolyte;
• an object immersed in the electrolyte filled in the processing tub to be processed by the electrochemical machine;
• a storage unit storing the electrolyte;
• an electrolyte supply unit configured to supply the electrolyte stored in the storage unit to the processing tub;
• a manifold comprising an inflow path, to which the electrolyte supplied by the electrolyte supply unit flows, and an outflow path connected to the inflow path for discharging the electrolyte flowing from the inflow path to the object, wherein a discharge hole of the outflow path is immersed in the electrolyte filled in the processing tub;
• an electrode provided to the manifold to be electrically connected to the object, the electrode extending along the outflow path while being accommodated within the outflow path;
• and
• a power unit configured to supply power to the electrode and the object,
• wherein the manifold further comprises:
• a hollow hole extending within the manifold and accommodating the electrode;
• a boss protruding outwardly from the manifold and having a through hole communicating with the hollow hole to accommodate the electrode;
• a first fixing nut configured to be coupled to the boss and having a though hole communicating with the through hole of the boss to accommodate the electrode;
• a first fixing ring interposed between an end of the boss and the first fixing nut and directly facing the electrode, the first fixing ring expanding toward the electrode while being compressed by the first fixing nut and directly contacting the electrode to hold the electrode at a center of the hollow hole;
• a recess formed within the manifold and communicating with the hollow hole to accommodate the electrode;
• a second fixing nut configured to be coupled to the recess while being inserted into the recess and having a through hole communicating with the hollow hole to accommodate the electrode;
• and
• a second fixing ring interposed between the second fixing nut and a base of the recess and directly facing the electrode, the second fixing ring expanding toward the electrode while being compressed by the second fixing nut and directly contacting the electrode to hold the electrode at the center of the hollow hole.
