The wireless receiving and heating device 20 of the present invention utilizes the electromagnetic induction heating principle in the wireless charging and transmitting device 10, and the heating principle is related to the eddy current; the electric energy is changed through the magnetic field and then converted into heat energy in the ferromagnetic metal above the electric energy. Fig. 2 is a perspective view of an implementation device of the wireless charging and transmitting device 10.
In fig. 3 and 4, the first embodiment of the wireless receiving and heating system with communication function of the present invention includes the wireless charging and transmitting device 10 and the wireless receiving and heating device 20, wherein the wireless charging and transmitting device 10 includes a housing 11, a transmitting coil 16 and a transmitting disc 14, and the housing 11 is the housing 11 shown in the appearance of the wireless charging and transmitting device 10 shown in fig. 2. The transmitting end coil 16 is arranged at the top in the shell 11; a transmitting side antipad 14 is disposed within the housing 11 and below the transmitting side coil 16. The wireless receiving and heating device 10 is disposed on the upper surface of the wireless charging and transmitting device 10, that is, on the upper surface of the housing 11 of the wireless charging and transmitting device 10, and includes a receiving portion 21 (as shown in fig. 1), a metal heating plate 22, a receiving-end magnetic separating disc 24, a receiving-end wireless communication device 25, and a receiving-end coil 26.

In one embodiment, the receiving wireless communication device 25 is disposed between the receiving magnetic isolation disc 24 and the receiving coil 26; the receiving-side wireless communication device 25 and the receiving-side coil 26 may be disposed on the same plane, that is, the receiving-side wireless communication device 25 may be disposed on both sides of the receiving-side coil 26. The receiving-end wireless communication device 25 can perform communication between the wireless reception heating device 20 of the present invention and the wireless charging transmission device 10 to transmit temperature data and transmit a signal controlling temperature.
The wireless charging and transmitting device 10 of the present invention transmits energy to the wireless receiving and heating device 20 by near-field induction, i.e. inductive coupling, and enables the contents of the accommodating portion 21 in the wireless receiving and heating device 20 to be heated; and the wireless receiving and heating device 20 can perform the function of informing the wireless charging and transmitting device 10 to increase or decrease the energy transmission in digital communication so as to control the heating temperature adjustment.
The metal heater plate 22 functions primarily as a heating region, and outside the region of the receiving end separated from the disk 24, when the changing magnetic field encounters a conductor such as metal, which is a monolithic piece of metal, an eddy current effect is created. The eddy current generates a large amount of heat, and like an induction cooker, the eddy current effect can be utilized to convert electric energy into heat energy.
The transmitting end magnetic isolation disc 14 and the receiving end magnetic isolation disc 24 have the functions of magnetic conduction and magnetic blocking. The magnetic conduction function is explained by taking the Qi wireless charging standard as an example, and the principle is electromagnetic induction. The transmitting end of the wireless charging generates an interactive magnetic field, and in order to enable the magnetic field energy transmitted by the primary coil to act on the receiving end of the wireless charging as much as possible, the magnetic of the coil 16 of the transmitting end needs to be guided. In addition, after the receiving-end magnetic shielding disc 24 is added to the receiving-end coil 26, the magnetic lines of force will be concentrated, and the magnetic lines of force will be relatively dispersed in the area without the magnetic shielding disc guide. The magnetic shield disk 24 region at the receiving end should not only be able to conduct magnetism effectively, but also play a role in magnetic shield. The purpose of the magnetic shield is to constrain the magnetic field generated by the wireless charging transmitter so that the magnetic field can only act on the receiver coil 26.
The receiving end coil 26 adopts a non-contact close-range coil resonance principle to transmit energy and communication transmission, wherein a coil is arranged at each of the transmitting end and the receiving end, and the transmitting end coil 16 is used for generating electromagnetic signals; the receiving coil 26 is small and generates power by inducing the electromagnetic signal of the transmitting end to provide power for the operation of the wireless receiving heating device 20.
Fig. 5 is a view from V to V of fig. 4, that is, fig. 5 is a schematic view of a bottom implementation of the wireless receiving and heating device of fig. 4, in which the metallic heating plate 22, the receiving-end magnetic separation disc 24 and the receiving-end coil 26 are related, and a temperature sensor 28 and a control unit 27 are included in the wireless receiving and heating device 20; the temperature sensor 28 is disposed below the metal heating plate 22 for detecting the temperature of the metal heating plate 22; the control unit 27 is coupled to the temperature sensor 28, coupled to the receiving coil 26, and disposed under the receiving diaphragm 24. The control unit 27 can transmit the temperature information to the transmitting end coil by a backscatter modulation through the receiving end coil 26, which can be a transmission mode of one-way communication.
The control unit 27 and the temperature sensor 28 in fig. 5 are mainly used for temperature sensing and wireless communication transmission. When the standard wireless charging and transmitting device 10 below performs energy transmission on the wireless receiving and heating device 20, the electromagnetic signal of the transmitting end generates power supply through the action of the receiving end coil 26, and the power supply is provided to the control unit 27, and the control unit 27 starts to detect the temperature through the temperature sensor 28. When the temperature is higher than the set value, the control unit 27 transmits the temperature information to the transmitting terminal coil 16 through the receiving terminal coil 26 by backscattering modulation to inform the transmitting terminal of reducing power transmission; when the temperature is lower than the set value, the control unit 27 transmits the temperature information to the transmitting end coil 16 through the receiving end coil 26 by backscatter modulation to inform the transmitting end of transmitting of increasing power, thereby achieving the effect of stabilizing the temperature.
Fig. 6 mainly illustrates the circuit blocks inside the control unit 27, and the control unit 27 includes a rectifying unit 32, a voltage reducing unit 34, a voltage stabilizing unit 36 and a microcontroller 30. The rectifying unit 32 is coupled to the receiving end coil 26, and is used for rectifying the electrical signal of the receiving end coil 26; the voltage reducing unit 34 is coupled to the rectifying unit 32, and mainly reduces the output voltage of the rectifying unit 32 to reduce the output voltage; the voltage stabilizing unit 36 is coupled to the voltage reducing unit 34, and is used for stabilizing the voltage value output by the voltage reducing unit 34, so as to avoid the unstable voltage; the microcontroller 30 is coupled to the voltage stabilizing unit 36, the temperature sensor 28, and both ends of the receiving end coil 26, as shown in fig. 6, for performing temperature control after temperature sensing and wireless communication transmission.
Furthermore, the present invention transmits energy to the upper wireless receiving and heating device 20 by the transmission of the wireless charging and transmitting device 10, and provides the energy received by the sensing devices such as the control unit 27 and the temperature sensor 28 for its operation, and at the same time, the control unit 27 detects the temperature of the upper ferromagnetic metal converted thermal energy, and transmits the data of energy control to the lower wireless charging and transmitting device 10, and the temperature value can be used as the basis of energy control, thereby achieving the purpose of controlling the magnitude of the transmitted energy of the wireless charging device.
The working mode of the invention on communication is that the upper heating device informs the wireless charging transmitting device to increase or decrease the electric quantity in a digital communication mode so as to achieve the effect of stabilizing the heating temperature. The digital communication mode can be one-way or two-way communication; during two-way communication, the wireless charging and transmitting device 10 transmits the temperature information to the receiving coil 26 in a Frequency Modulation (FM) transmission manner, and then transmits the temperature information back to the transmitting coil 16 of the wireless charging and transmitting device 10 in a backscatter modulation manner to generate a required control signal. Furthermore, unidirectional communication can also be performed using the backscatter modulation alone.
