The utility model relates to an electromagnetic pneumatic damping open device for a door of a refrigerator. The utility model is composed of an electromagnet (1), an electromagnet reset spring (4), a damping cylinder (23), a bumper pad (2) and a fixed striking pad block (3) on a door body of the refrigerator. After the utility model is switched on, electromagnetic armature iron (7) pushes a piston rod (24) of the damping cylinder (23), a compression reset spring (4) and a piston (22) to forward move under the function of the magnetic field of an electromagnet coil (8). Air is absorbed by a big hole (13) which is arranged on the cylinder body (23), and the air which is compressed in the cylinder body (23) is gradually exhausted by a throttling effect of a throttling small hole (26). The armature iron (7) stably drives the piston rod (24) and the bumper pad (2) which is fixed on piston rod to extend out of an opening hole (27), and then, a door is slowly opened. Simultaneously, the utility model is automatically switched off, and the electromagnetic armature iron (7) automatically resets. When turned on, the open device does not generate impact, and articles in a hand are stable so that the articles can not scatter.
