B. the Electromagnetic Compatibility (EMC) of the equipment or the system in the Electromagnetic environment of the mini Electromagnetic oven cannot meet the requirement and cannot generate intolerable Electromagnetic Disturbance to any equipment in the environment, so that the EMC comprises the requirements of not exceeding a certain limit value for the Electromagnetic Disturbance (Electromagnetic Disturbance) generated by the equipment to the environment in the normal operation process on one hand and having a certain degree of immunity to the Electromagnetic Disturbance (EMS) in the environment on the other hand

C. The power cord of the existing induction cooker is designed to be integrated with the shell and cannot be taken down, and the power cord is inconvenient to store.

D. The heat dissipation port of the existing induction cooker is generally arranged below the bottom shell, which is not beneficial to the heat dissipation of the heating coil panel arranged on the upper shell; and the heat dissipation fan and the heat radiators of the power tubes on the control board are required to be placed in parallel (for example, the heat radiators are placed left and right), the fan sucks air from the lower part and blows the air from the upper part, the air path is vertical from the upper part to the lower part, but objects to be dissipated are deviated on the horizontal plane, and the heat radiators can only dissipate the heat through the wind pressure generated by the fan in the electromagnetic oven, so that the heat dissipation effect is greatly reduced.

E. The heating coil panel of the existing induction cooker is fully built-in and only has the single function of generating a variable magnetic field.

F. The radiator on the control panel of the existing induction cooker is large in thickness and large in occupied space.

The prior art needs to be improved and developed.
