Furthermore, the wireless power supply health pot heating device of the present invention, as a whole, obtains the transmission energy of the wireless power supply energy transmission device 30 as the energy required for heating of the upper device, and uses the wireless power supply energy transmission device. The principle of electromagnetic induction makes it possible to heat the rear end of the health pot. And perform wireless communication transmission between the two, the communication method is to use radio frequency (RF) communication devices such as 433MHz or 2.4G. First, the wireless power supply energy transmitter 30 transmits a small part of the energy to the wireless power receiving end health pot 10 above. The wireless power receiving end health pot 10 induces energy and uses the received energy for its own operation, and at the same time Detect and communicate with the lower transmitter wireless communication device 36, and after the communication confirms the existence of the wireless power receiving end, the energy control data is transmitted to the lower wireless power energy transmitter 30, and then the temperature value is used as energy control According to this, the relevant control of the transmitting energy of the wireless power supply energy transmitting device 30 is achieved.

Effect. The digital communication method can be one-way or two-way communication. When the wireless power supply energy transmitting device 30 transmits a small part of the energy to the upper wireless power supply receiving end health pot 10, if no response from the receiving end wireless communication device 16 is received, but a metal object is sensed above The lower wireless power supply energy transmitting device 30 is changed to the induction cooker mode, which directly heats the metal cookware above. The wireless power supply health pot heating device of the present invention transmits in the manner of a wireless power supply device, and uses the principle of electromagnetic induction heating to generate electrical energy. Through the change of the magnetic field, the ferromagnetic metal above is converted into heat energy.

The AC power of this specific frequency drives the energy transmitting unit 374 composed of a transmitting coil and a resonant capacitor to generate alternating changes in the upper magnetic field. The phenomenon of energy transmission to the upper energy receiving end, this energy receiving end can be a general ferromagnetic pot, or an inductance coil made of copper wire for receiving energy, such as the wireless power receiving end of the present invention The receiving end coil 18 installed in the health pot 10.

One end of the temperature heating device 171 is coupled to one end of the receiving end coil 18. One end of the AC switch controller 172 is coupled to the other end of the receiving end coil 18, and the other end of the AC switch controller 172 is coupled to the other end of the temperature heating device 171. The two input ends of the voltage control unit 173 are respectively coupled to one end of the receiving end coil 18 and the other end of the receiving end coil 18, as shown in FIG. 6. The microcontroller device 174 is bidirectionally coupled to the receiving wireless communication device 16, and is coupled to the output signal of the voltage control unit 173, and outputs the control signal to the AC switch controller 172. In addition, the input end of the temperature sensor 19 is coupled to the temperature heating device 171, and the output end of the temperature sensor 19 is coupled to the microcontroller device 174 for detecting the temperature value of the health pot 10 at the wireless power supply receiving end.

Furthermore, the microcontroller device 174 and the temperature sensor 19 of the health pot 10 at the wireless power supply receiving end in FIG. 6 are mainly used for temperature sensing and wireless communication transmission. When the lower wireless power supply energy transmitting device 30 transmits energy to the wireless power supply receiving end health pot 10, the electromagnetic signal at the transmitting end generates power to provide the wireless power supply receiving end health pot 10, so that the microcontroller device 174 The temperature sensor 19 will start to detect the temperature. When the temperature is higher than a preset value, the microcontroller device 174 transmits the information to the transmitter coil 38 through the receiver wireless communication device 16, so as to notify the wireless power transmitter 30 below to reduce the power transmission. In addition, when the temperature is lower than the set value, the microcontroller device 174 transmits information to the wireless power transmitting device 30 through the receiving end wireless communication device 16, so as to notify the transmitting end to increase the power transmission, so as to achieve the effect of stabilizing the temperature. .

FIG. 7 is a schematic diagram of the operation sequence of wireless power supply according to an embodiment of the present invention. It includes five operation timings and processes: the driving signal of the energy transmitting terminal, the wireless communication signal of the energy transmitting terminal, the energy transmitting terminal of the energy transmitting terminal, the wireless communication signal of the energy receiving terminal, and the energy receiving terminal receiving energy. The receiving end coil 18 of the wireless power supply receiving end health pot 10 of the present invention uses non-contact close electromagnetic induction and inductance-capacitance resonance principles to transmit energy. Each of the wireless power supply transmitting end and the wireless power supply receiving end has a coil (ie, the transmitting end coil 38 and the receiving end coil 18), and the transmitting end is used to alternately change the magnetic field to transmit energy to the receiving end. In addition, the signals of the actual system operation are operated by the sequence and flow as shown in FIG. 7. Among them, the microcontroller unit 376 at the end of the wireless power supply energy transmitting device 30 will send out a short specific frequency PWM signal at a fixed interval to drive the inverter to operate and transmit energy. This purpose is to detect objects. When any receiving end (ferromagnetic pot and coil inductance) that can be heated is placed, the system power of the wireless power supply energy transmitting device 30 will change when the energy is sent. At time t1 in Figure 7, After placing the heating device on the wireless power transmitting device 30, the wireless power transmitting device 30 will increase the system current due to electromagnetic induction. At this time, it means that there is a heating object above the wireless power transmitting device 30. Place it on it, but we still need to confirm that the object is a general pot, or an energy receiving end with communication control function, such as the wireless power receiving end health pot 10 of the present invention.

Therefore, at the time point of t2, the wireless power supply energy transmitting device 30 starts to send the specific frequency PWM signal to drive the inverter. The purpose of this transmission energy is to identify and detect (the energy transmitting terminal at t2 in Figure 7 transmits The identification and detection of the driving signal of energy), the energy sent by this identification detection will be less than the energy in the energy detection stage, but it is enough for the microcontroller device 174 of the health pot 10 and the receiving side to communicate wirelessly. Device 16 is operating. After the wireless power supply receiving end health pot 10 receives the identification and detection energy, it must use the receiving end wireless communication device 16 of the wireless power supply receiving end health pot 10 to send a signal to the wireless power supply energy transmitting device 30 within the agreed time. End wireless communication device 36. After that, at the time point of t3, the microcontroller unit 376 of the wireless power transmitting device 30 receives the identification signal from the wireless communication device 36 of the transmitting terminal, and the wireless power transmitting device 30 will confirm that it is placed The upper device is the wireless power receiving end health pot 10 of the present invention. After that, it starts to adjust the PWM frequency to drive the inverter to continuously send energy, and the receiving end coil 18 induces the electromagnetic field of the transmitting end coil 38 to generate power. It is converted to heat energy and heating is performed.

FIG. 8 is a schematic diagram of the signal sequence flow diagram of the health pot at the wireless power receiving end during heating according to the embodiment of the present invention. It also includes five operation timings and processes: the driving signal of the energy transmitting end, the wireless communication signal of the energy transmitting end, the energy transmitting end of the energy transmitting end, the wireless communication signal of the energy receiving end, and the energy receiving end of the energy receiving end. Fig. 8 mainly shows that when the wireless power supply receiving end health pot 10 enters the continuous heating process, it must send heating information to the transmitting end wireless communication device 36 through the receiving end wireless communication device 16 according to a fixed time period agreed in advance, as shown in Fig. 8 The heating information disclosed in is sent by the wireless communication signal of the energy receiving end, and the wireless communication signal of the energy transmitting end makes a response information. Then, after the microcontroller unit 376 receives the heating information at the wireless power supply energy transmitting device 30, it controls the PWM frequency of the inverter and controls the duty cycle to achieve the purpose of adjusting the transmitted energy. In this way, the received energy of the health pot 10 at the wireless power supply receiving end can be adjusted toward the set target. Among them, the time sequence of the energy receiving end receiving energy, the energy increases at time ta, which is the state of continuous heating; at time tb, due to the continuous heating, the energy accumulates and increases again, and it is also in the state of continuous heating. After that, at time tc, the energy transmitting end stops sending energy, so that the energy received by the energy receiving end also decreases, that is, it stops heating to maintain a fixed temperature. On the contrary, if the temperature is lower than a set value, the energy transmitting terminal starts to emit energy, so that the energy receiving terminal can receive energy again for heating.

FIG. 9 is a schematic diagram of the operation sequence of the induction cooker mode of the embodiment of the present invention, which illustrates that in another embodiment, when the wireless power supply energy transmitter 30 is transmitting energy detection, the situation shown in FIG. 9 is generated, which is If the receiving end device placed is a pot for general induction cooker, at this time, the energy transmitting end will consume a lot of power due to electromagnetic coupling. If the power consumption is large enough or the resonance frequency of the energy transmitting unit is small enough At this time, it is expected that there is a pot to perform detection and communication confirmation. After t2, the microcontroller unit 376 starts to send identification and detection energy with a smaller power. If after several consecutive times, there is no receiving end wireless communication device 16 When communicating signals, it will switch to the induction cooker mode at time t3. That is, the wireless power supply energy transmitter 30 of the present invention can be used in general cookware, can be used as an induction cooker, and can be used by users through A button or touch screen on a human-machine interface of the wireless power supply energy transmitting device 30 controls the heating strength of the wireless power supply energy transmitting device 30.

In summary, in the present invention, two devices such as the wireless power supply energy transmitter 30 and the upper wireless power supply energy receiving end sample pot 10 are used to transmit energy through inductive coupling, so that no joint connection is required between the two. Effectively improve the lack of conventional technology. Therefore, when the device is actually manufactured, the wireless power supply energy transmitting device 30 and the wireless power supply energy receiving end sample pot 10 and other devices placed on the upper side can both achieve no conductive contacts exposed. Therefore, the cleaning and cleaning of the health pot is safer and more convenient than the existing contact type health pot. At the same time, the lack of contacts also makes the overall appearance more beautiful, and can greatly save the expensive cost of patented joints. In addition, the wireless power transmitting device 30 below can also be used for heating general pots, that is, the device placed above can be a general pot, but the wireless power transmitting device 30 is regarded as a small Induction cooker use. Obviously, the technical content of the present invention has extremely strong patent application requirements.

However, the content described in the description of the present invention is only an example of a preferred embodiment. When it cannot be used to limit the scope of protection of the present invention, any relevant partial changes, minor modifications, amendments, or added technologies, or numerically Or changes in position, etc., still do not depart from the scope of protection of the present invention.
