Title:
WIRELESS POWER SUPPLY SYSTEM FOR COOKING APPLIANCE, AND COOKING APPLIANCE
Document Type and Number:
WIPO Patent Application WO/2019/037334
Kind Code:
A1
Abstract:
Disclosed in the present invention are a wireless power supply system for a cooking appliance, and a cooking appliance. Said system comprises: a receiving device comprising a receiving coil, a voltage processing circuit connected to the receiving coil, a first control chip and a first communication demodulating circuit; and a transmitting device comprising a transmitting coil, a coil driving circuit and a second control chip, the transmitting coil matching the receiving coil. The second control chip controls the coil driving circuit, so as to change the resonant voltage of the transmitting coil, and change the induced voltage signal generated by the receiving coil; and the first communication demodulating circuit demodulates the changed induced voltage signal to output the demodulated data to the first control chip, so as to implement wireless communication between the first control chip and the second control chip. The wireless power supply system can realize wireless communication from a transmitting end to a receiving end of the cooking appliance, such that the receiving end can control the cooking appliance according to the data sent by the transmitting end, improving the intelligence of the cooking appliance.
