Problems solved by technology
[0002] The air duct of the existing induction cooker makes the air distribution of the fan too scattered, and the cooling efficiency is not high
In addition, there is a metal partition shielding requirement between the coupling coil of the transmitting end of the wireless high-power transmitter and the circuit board, which will affect the cooling effect of the coil
For the two induction cooker structures proposed by patents CN1920398A and CN201827931U, if the partition plate is not made of metal and is not in the projection area directly below the coil, it cannot meet the electromagnetic shielding requirements between the circuit board and the transmitting coil, and the circuit board and the coil are separated from each other. Not using as much air volume as possible from the fan

The invention discloses a kitchen wireless power transmitter air cooling structure which comprises a base casing, a circuit board, a transmitting coupling coil, an upper panel and a fan and further comprises a shielding aluminum plate. An inner cavity is formed between the upper panel and the base casing, the shielding aluminum plate is located in the middle of the inner cavity and divides the inner cavity into an upper cavity and a lower cavity, the transmitting coupling coil is located in the upper cavity and arranged above the shielding aluminum substrate, and the circuit board is located in the lower cavity. By means of the shielding aluminum plate, an electromagnetic shielding effect is achieved on a machine main board, meanwhile the shielding aluminum plate divides the machine inner space into the upper cavity and the lower cavity, the upper cavity and the lower cavity form two radiating channels which are connected in series, and radiating of the kitchen wireless power transmitter is facilitated during long-time work.
Description
technical field [0001] The invention relates to a kitchen wireless power transmitter, in particular to an air-cooled structure of a kitchen wireless power transmitter. Background technique [0002] The air duct of the existing induction cooker makes the air distribution of the fan too scattered, and the cooling efficiency is not high. In addition, there is a requirement for metal partition shielding between the coupling coil of the transmitting end of the wireless high-power transmitter and the circuit board, which will affect the cooling effect of the coil. For the two induction cooker structures proposed by patents CN1920398A and CN201827931U, if the partition plate is not made of metal and is not in the projection area directly below the coil, it cannot meet the electromagnetic shielding requirements between the circuit board and the transmitting coil, and the circuit board and the coil are separated from each other. Not using as much air flow as possible from the fan. ...
