The invention discloses an electric appliance for cooking. The electric appliance for cooking comprises a cavity, a hot air assembly and a metallic sealed net ring, wherein the cavity comprises a sideplate, and a side play through hole is formed in the side plate; the hot air assembly comprises a motor which is installed on the outer surface of the side plate, and the motor comprises a motor shaft which can penetrate through the side plate through hole and rotate around the axis; the sealed net ring is installed on the inner surface of the side plate, the motor shaft can penetrate through a net ring through hole and rotate around the axis, and the distance between the inner wall of the net ring through hole and the motor shaft is smaller than 1 mm. In the electric appliance for cooking, the sealed net ring fills the gap between the motor shaft and the side plate through hole so that microwaves can be prevented from being leaked outwards from the inside of the cavity, and the safety performance of the product is improved. Besides, the sealed net ring has the function that the heat in the cavity is prevented from being leaked outwards, the heat loss is reduced, the energy consumption is reduced, and the energy-saving and environment-friendly performance of the electric appliance for cooking is improved.
