The invention discloses a paint-immersion process for a motor coil of a washing machine. The paint-immersion process comprises the following steps of S1: preparing materials and tools; S2: preparing an immersion solution; S3: starting the general power supply of an automatic immersion machine, setting the voltage, choosing an automatic working mode, regulating the pitch time, and setting a preheating temperature; S4: starting a heater, an air heater and a circulating fan, enabling the automatic immersion machine to perform preheating and cooling operations, and putting a coil-inserting stator on the station of the automatic immersion machine after the cooling operation is finished; S5: performing operations of paint immersion, paint dripping, curing and workpiece taking-out; S6: removing residual paint by a scraper knife; S7: performing examination; and S8: switching off the power supply after the obtained workpiece is qualified through examination. The paint-immersion process provided by the invention is complete, and simple to operate; the surface of the immersed paint film is uniform without causing phenomena of cracks, wrinkles and exposed wires; and in addition, the paint film is firm and the paint does not fall off easily, so that high safety is achieved.
