A cooking appliance and a wireless control system thereof according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1, the wireless control system of the cooking appliance includes: a radio receiver apparatus 10 and a radio transmitter apparatus 20.
The wireless receiving device 10 is arranged in the cooker cover 1, the wireless receiving device 10 comprises a first coupling circuit 11, a voltage stabilizing circuit 12 and a first control unit 13, wherein the voltage stabilizing circuit 12 is used for outputting a stable power supply to supply power to the first control unit 13 and the pressure regulating valve 3, and the first control unit 13 is connected with the pressure regulating valve 3 to control the pressure regulating valve 3. The wireless transmitting device 20 is arranged in the pot body 2, the wireless transmitting device 20 comprises a second coupling circuit 21 and a second control unit 22, and the second control unit 22 controls the second coupling circuit 21 to enable the second coupling circuit 21 to be coupled with the first coupling circuit 11 through electromagnetic signals so as to supply power to the voltage stabilizing circuit 12 in a wireless mode.
Specifically, in one embodiment of the present invention, the first coupling circuit 11 includes a receiving coil panel, the second coupling circuit 21 includes a transmitting coil panel, and wireless electromagnetic signal transmission is possible between the receiving coil panel and the transmitting coil panel.
In an embodiment of the present invention, as shown in fig. 3, the wireless receiving apparatus 10 may further include a first driving circuit 14, the first driving circuit 14 is respectively connected to the first control unit 13 and the first coupling circuit 11, the first control unit 13 is further configured to obtain a pressure parameter in the cooking appliance, and control the first driving circuit 14 to drive the first coupling circuit 11, so that the first coupling circuit 11 sends the first wireless electromagnetic signal to the second coupling circuit 21.
As shown in fig. 3, the first driving circuit 14 is connected to the regulator circuit 12 to supply power to the first driving circuit 14 through the regulator circuit 12.
It should be noted that the first control unit 13 may include a corresponding modulation module and a demodulation module, where the modulation module is configured to modulate the temperature (which is a digital signal) in the cooking appliance into a temperature signal (which is an analog signal), where the temperature signal is a pressure parameter.
Further, the second coupling circuit 21 is connected to the second control unit 22, and the second control unit 22 receives the first electromagnetic signal through the second coupling circuit 21 to obtain the pressure parameter.
In an embodiment of the present invention, as shown in fig. 3, the wireless transmitting device 20 may further include a second driving circuit 23, the second driving circuit 23 is respectively connected to the second control unit 22 and the second coupling circuit 21, the second control unit 22 is further configured to output a pressure control instruction, and control the second driving circuit 23 to drive the second coupling circuit 21, so that the second coupling circuit 21 transmits a second wireless electromagnetic signal to the first coupling circuit 11.
It should be noted that the second control unit 22 may include a corresponding modulation module and a demodulation module, and after the second control unit 22 obtains the temperature signal (i.e., the pressure parameter), the demodulation module demodulates the pressure in the cooking appliance corresponding to the temperature signal, and further modulates the pressure into the pressure control command through the modulation module.
Further, the first coupling circuit 11 is connected to the first control unit 13, and the first control unit 13 receives the second wireless electromagnetic signal through the first coupling circuit 11 to obtain the pressure control instruction.
Furthermore, after the first control unit 13 obtains the pressure control command, it demodulates the corresponding pressure from the pressure control command through the demodulation module, and controls the pressure regulating valve 3 to operate, so that the pressure regulating valve 3 opens by the corresponding size. The opening size of the pressure regulating valve 3 corresponds to the pressure demodulated from the pressure control command.
It will be appreciated that the wireless receiving device 10 and the wireless transmitting device 20 may each include a corresponding resonant capacitor, and may also each include at least a corresponding capacitor in series with the switch, which may be used to change a resonant state parameter of the resonant circuit, such as resonant voltage amplitude, resonant frequency, etc.
It should be noted that in one embodiment of the present invention, the energy transfer may be performed by using electromagnetic signal coupling between the receiving coil disk and the transmitting coil disk. Specifically, the first high-frequency signal output from the second control unit 22 causes high-frequency resonance between the transmitting coil disk and the corresponding resonance capacitor via the second drive circuit 23, the high-frequency resonance generates electromagnetic field variation to be coupled to the receiving coil disk, high-frequency resonance of the same frequency is also generated between the receiving coil disk and the corresponding resonance capacitor, and the rectified and filtered dc regulated voltage is supplied to the first control unit 13, the pressure regulating valve 3, and the first drive circuit 14 via the voltage regulator circuit 12, thereby realizing wireless power supply.
Furthermore, signals can be transmitted by utilizing electromagnetic signal coupling between the receiving coil panel and the transmitting coil panel, and bidirectional communication is realized. Specifically, when the wireless transmitter 20 transmits the second wireless electromagnetic signal to the wireless receiver 10, the transmitting coil panel determines whether the transmitted data is O or 1 according to whether the second control unit 22 outputs the second high-frequency signal. When the 0 data needs to be transmitted, the second control unit 22 stops outputting the second high-frequency signal for a certain time; when the data 1 needs to be sent, the second control unit 22 continuously outputs the second high-frequency signal for a certain time, so that the first control unit 13 can identify the data sequence O and 1 sent by the sending coil disk through the demodulation module, and obtain the pressure control command according to the data sequence 0 and 1. When the wireless receiving device 10 transmits the first wireless electromagnetic signal to the wireless transmitting device 20, the receiving coil disc outputs a signal to the corresponding modulation module through the first control unit 13. When the data of 0 needs to be transmitted, the first control unit 13 outputs a specific level signal, and the switch is turned on, so that the capacitor is connected in series or in parallel to a resonance circuit formed by the receiving coil disc and the resonance capacitor, so as to change the resonance state parameter (such as the resonance voltage amplitude or the resonance frequency); when 1 data needs to be sent, the first control unit 13 outputs a reverse signal, the switch is turned off, the capacitor is not connected to the resonant circuit, that is, the resonant circuit parameter of the wireless receiving device 10 is not changed, so that the second control unit 22 can identify the O and 1 data sequences sent by the receiving coil disc through the demodulation module and acquire the pressure parameter according to the 0 and 1 data sequences.
It will be understood that a change in the resonance state parameter of the radio receiver apparatus 10 affects the resonance state of the radio transmitter apparatus 20 by coupling, and the second control unit 22 can identify the resonance state parameter (resonance voltage amplitude or resonance frequency) of the transmitting coil disk by the corresponding demodulation module.
The power of the first high-frequency signal may be different from that of the second high-frequency signal, and for example, the power of the first high-frequency signal may be larger than that of the second high-frequency signal, and whether the energy or the signal is transmitted by the electromagnetic signal coupling between the receiving coil disk and the transmitting coil disk may be determined according to the power of the high-frequency signal.
For example, after the pot cover 1 is closed, the voltage stabilizing circuit 12 provides a stable voltage to the first driving circuit 14, the first control unit 13 and the pressure regulating valve 3, a user can input a control command through the function key to heat food materials in the pot body 2, the temperature and the pressure in the pot body 2 start to rise, the first control unit 13 can acquire the temperature in the cooking appliance in real time and modulate the temperature into a corresponding temperature signal (i.e., a pressure parameter) through the modulation module, and then the first control unit 13 controls the first driving circuit 14 to drive the first coupling circuit 11, so that the first coupling circuit 11 sends a first radio magnetic signal corresponding to the temperature signal to the second coupling circuit 21, and the second control unit 22 receives the first radio magnetic signal through the second coupling circuit 21 to acquire the temperature signal; the second control unit 22 can demodulate the pressure in the cooking appliance corresponding to the temperature signal through the demodulation module, and modulate the pressure into a pressure control command through the modulation module, the second control unit 22 drives the second coupling circuit 21 by controlling the second driving circuit 23, so that the second coupling circuit 21 sends a second wireless electromagnetic signal corresponding to the pressure control command to the first coupling circuit 11, the first control unit 13 receives the second wireless electromagnetic signal through the first coupling circuit 11 to obtain the pressure control command, and demodulates the pressure corresponding to the pressure control command through the demodulation module, and further controls the pressure regulating valve 3 to perform corresponding exhaust and pressure relief actions according to the pressure. Therefore, in the cooking process of the cooking appliance, the food materials are turned over by discontinuously exhausting air through the pressure regulating valve 3, and the cooking effect is improved.
It should be noted that the function keys may be disposed on the cooking appliance, such as the lid and the body, or may be disposed on a separate control device, such as other intelligent terminals.
