1Object-affected harmful factors
If a blocking structure is provided to block electromagnetic fields and waves, then electromagnetic interference is reduced, but wireless communication performance deteriorates
Solution Approach 1:
The patent positions the wireless communication circuit board in the vertical dimension above the cooking surface, while blocking structures are placed in the horizontal plane below. This spatial separation in different dimensions allows the blocking structures to shield electromagnetic interference without obstructing the vertical path of radio waves for wireless communication.
Solution Approach 2:
The blocking structures are selectively positioned only in specific locations where electromagnetic interference originates (below the cooking surface near heating elements), while leaving other areas open for wireless communication. This localized shielding approach blocks harmful electromagnetic fields while maintaining communication performance in critical zones.
2Device complexity
If the circuit board is positioned close to metal components for compact design, then spatial efficiency is improved, but electromagnetic interference increases
Solution Approach 1:
The circuit board is positioned in the vertical dimension above the cooking surface, separated from metal components in the horizontal plane below. This dimensional separation maintains compact overall design while preventing direct contact and electromagnetic coupling between the circuit board and metal heating components.
Solution Approach 2:
Non-metallic support structures and insulation materials are introduced as intermediary elements between the circuit board and metal components. These intermediaries provide physical support and mounting while electrically isolating the circuit board from electromagnetic fields generated by metal heating elements.
