Problems solved by technology
Its weak point is: because electromagnetic cooker 11 is placed on the platen 3, thermistor 5 is installed below the platen 3, the temperature of electromagnetic cooker 11 can only pass to thermistor 5 through platen 3, and existing The material of the platen in the technology is usually crystallized glass or ceramic plate, which has poor thermal conductivity. In addition, there may be poor contact between the platen 3 and the thermistor 5 during the installation process.
Therefore, using this contact temperature detection method, it is difficult to ensure that the temperature of the electromagnetic cooker 11 is accurately and timely transmitted to the thermistor 5, especially at a specific temperature point, the thermistor 5 cannot be accurately and timely. Signal
Therefore, it is difficult for the electromagnetic cooker in the prior art to realize accurate and automatic control of the oven temperature during the cooking process.
In this case, it is very inconvenient to manually change the program for cooking that does not require too much cooking skills and takes a long time.
Thus limiting the development of electromagnetic cooker

Electromagnetic cooker includes shell body, bedplate, heating coil, control board, bracket, heat elimination mechanism, and temperature sensing unit. Temperature sensing unit on middle part under the bedplate adopts magneto-dependent sensor. Beign fixed under the bedplate by bracket, the magneto-dependent sensor is in use for receiving magnetic signal sent from temperature sensing magnet steel of sensing heat conduction of pan bottom at setting temperature point. Thus, based on sensed signal, the magneto-dependent sensor can switch programs controlled by temperature. The electromagnetic cooker can design accurate automatic control program so as to reach effect of automatic electric cooker without need of taking charge for cooking rice. The electromagnetic cooker possesses advantages of accurate and timely detection.
Description
technical field [0001] The invention relates to an electromagnetic cooker, in particular to an electromagnetic cooker capable of automatic temperature control during cooking. Background technique [0002] An induction cooker is a household appliance that uses a magnetic field to directly heat an electromagnetic cooker made of ferromagnetic materials as a load for cooking. The electromagnetic cooker in the prior art uses the temperature conduction of the bottom of the pot to control the temperature: during the cooking process of the electromagnetic cooker, the heat generated by the bottom of the pot placed on the plate of the electromagnetic cooker is directly transferred to the plate, and is installed under the cooker plate. The thermal sensor detects the temperature of the bottom of the pot, and then performs program control or safety protection according to the temperature felt. Such as figure 1 , 2 As shown, when the thermistor 5 of the electromagnetic cooker senses th...
