Although various aspects of the embodiments are illustrated in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The word "exemplary" is used herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.
In addition, numerous specific details are set forth in the following detailed description in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements, and circuits well known to those skilled in the art have not been described in detail in order not to obscure the present disclosure.
Fig. 1 shows a schematic diagram of an electromagnetic heating system according to an embodiment of the present disclosure. As shown in fig. 1, the electromagnetic heating system of the embodiment of the present disclosure may include a heating coil 10, a pan 11, a receiving coil 12, a temperature detection module 13, and a temperature control module 10.
In one possible implementation, the heating coil 10 in the electromagnetic heating system is used to generate a high frequency magnetic field under alternating current. In operation, the alternating current input to the heating coil 10 may be a current converted from commercial power, and the heating coil 10 may be a round, square or any regular or irregular shaped coil wound on a flat surface. During operation of the heating coil 10, an alternating current flows through the coil, creating a high frequency magnetic field that passes through the plane of the coil. The pan body 11 is disposed above the heating coil 10 during operation of the electromagnetic heating system, and is heated by a high-frequency magnetic field. Wherein, magnetic lines of force in the high-frequency magnetic field form a magnetic loop with the bottom of the pot 11 through the coil, and eddy current is formed at the bottom of the pot to heat the pot 11.
Optionally, a receiving coil 12 is further arranged on one side of the pot 11, and is used for generating voltage under the action of the high-frequency magnetic field. The receiving coil 12 is an inductive device capable of inducing the high-frequency magnetic field and converting the high-frequency magnetic field into an electric field. For example, the inductor can be a small-sized winding inductor, and the inductor is low in cost and occupies a small space. Alternatively, the receiving coil 12 may be a transformer, a small-sized coil, a single-turn wire, or the like, which can induce an inductive device that converts a spatial magnetic field into an electric field. In order not to increase the distance between the pan body 11 and the heating coil 10, the receiving coil 12 may be installed below the side of the pan body 11, and this position can be covered by a high-frequency magnetic field. The temperature detection module 13 is connected with the receiving coil 12, and is powered by the voltage generated by the receiving coil 12 and used for detecting the temperature of the pot body 10. The temperature detecting module 13 may be a temperature sensor such as a thermistor or a thermocouple resistor, and may be disposed at a position capable of detecting the temperature of the pot 11, such as at the bottom or side of the pot 11. The voltage generated by the receiving coil 12 can be used as the power supply voltage of the temperature detection module 13, so that no additional power supply is needed. The temperature measuring sensor such as the thermistor, the thermocouple resistor and the like can be arranged close to the pot body, and the resistance value is changed along with the change of the temperature of the pot body, so that the temperature of the pot body is obtained.
Further, a temperature control module 14 is further disposed at one side of the heating coil 10 and can be connected to the heating coil 10 for adjusting the alternating current of the heating coil 10 according to the temperature of the pan detected by the temperature detection module 13. Alternatively, the mapping relationship between the pan temperature and the alternating current may be set in the temperature control module 14, and for different heating modes, different mapping relationships may be set, and further, the alternating current may be adjusted according to the mapping relationship. For example, in the "high fire" heating mode, the temperature of the pan body at the target 10 is 200 degrees, and corresponding to this heating mode, the mapping relationship between the temperature of the pan body and the alternating current may be set, for example, 50 degrees to 100 degrees, corresponding to the alternating current I1, 100 degrees to 200 degrees, and the amplitude of the corresponding alternating current I2, I1 may be greater than I2, so that the temperature of the pan body can be quickly increased when the temperature of the pan body is low. After the temperature control module 14 obtains the temperature of the pan body, the power of the heating coil 10 can be adjusted to the target power by adjusting the alternating current, and finally the pan body 10 is efficiently heated to the target temperature.
In one possible implementation, the electromagnetic heating system of embodiments of the present disclosure is a split electromagnetic heating system comprising a heating appliance and a pan. Wherein, heating coil 10 and temperature control module 14 can set up in the heating utensil, and pot body 11, receiving coil 12 and temperature detection module 13 integrate in the pan.
Fig. 2 shows a schematic diagram of a module for temperature regulation according to an embodiment of the present disclosure. As shown in fig. 2, since the heating device and the cooker in the electromagnetic heating system are separately arranged, a communication module for transmitting the temperature of the cooker body between the heating device and the cooker can be further included in the electromagnetic heating system. I.e. the electromagnetic heating system may further comprise a first communication module connected to the temperature detection module 13 and a second communication module connected to the temperature control module 14. The first communication module is configured to send the pot temperature detected by the temperature detection module 13. The second communication module is configured to receive the pot temperature sent by the first communication module and transmit the pot temperature to the temperature control module 14. The first communication module may be integrated in a cooker as described above and the second communication module may be provided in a heater appliance.
Further, the voltage provided by the direct current supply to the receiving coil 12 can supply power to the first communication module and the temperature detection module 13 at the same time. Since the receiving coil 12 is an unstable voltage generated based on a high-frequency magnetic field, in order to improve the stability of the voltage provided by the receiving coil 12, a filtering voltage stabilizing module may be added in the electromagnetic heating system and connected to the receiving coil 12, so as to filter the voltage generated by the receiving coil 12, and obtain a stable voltage to be provided to the temperature detecting module 13 and the first communication module. Meanwhile, an overvoltage protection module for protecting the circuit in the cooker from being too high in voltage can be further included in the electromagnetic heating system. The overvoltage protection module is connected to the receiving coil, and can cut off the circuit when the voltage is too high, so as to protect the functional modules in the circuits such as the first communication module and/or the temperature detection module 13 which provide the voltage through the receiving coil 12.
In one possible implementation, any functional module that is powered by the receiving coil 12 may also be included in the electromagnetic heating system. For example, a display lamp may be included in the system, and the display lamp is connected to the receiving coil 12 and the temperature detecting module 13 and is powered by voltage, and is used for displaying corresponding colors according to the temperature of the pot detected by the temperature detecting module 13, for example, corresponding relationships between a plurality of temperature ranges and colors are preset, and corresponding colors are displayed according to the temperature range to which the current pot temperature belongs.
Optionally, the electromagnetic heating system may further comprise a sterilization module, which is disposed inside the pot body and connected with the receiving coil 12 and is powered by voltage, for sterilizing the inside of the pot body. The sterilization module can be an ultraviolet sterilization lamp and the like.
Further, the receiving coil 12 in the electromagnetic heating system is detachably connected to the pan body 11, for example, the receiving coil 12 can be connected to any type of pan based on the detachable connection, such as a snap connection or an adhesive connection. Other modules for supplying power to the receiving coil 12 are fixedly connected with the receiving coil 12 and are used for measuring temperature, displaying, communicating and operating the sterilizing lamp on any type of cookware. Meanwhile, because different cookware materials are different, the electromagnetic heating system can also comprise a material detection module which is connected with the receiving coil 12 and is powered by voltage and used for detecting the material of the cooker body 11 so as to adjust the power of the heating coil according to the material of the cooker body.
Based on the technical features, the receiving coil and the temperature detection module can be added in the separated electromagnetic heating system. In the use process of the electromagnetic heating system, the temperature of the pot body is detected in real time by supplying power to the temperature detection module through the receiving coil, and the temperature control module adjusts alternating current according to the temperature of the pot body, so that the temperature of the pot body is controlled in real time and flexibly. The temperature control module and the temperature detection module can conduct information transmission through the first communication module and the second communication module, and communication between the separated cookware and the heating appliance is achieved. Meanwhile, the stability of the output voltage of the receiving coil, the stability and the safety of the whole temperature detection and temperature transmission process are improved by adding the filtering voltage stabilizing module and the overvoltage protection module in the system.
The foregoing description of the embodiments of the present disclosure has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the various embodiments described. The terminology used herein was chosen in order to best explain the principles of the embodiments, the practical application, or the technical improvements in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
