Example Embodiment

[0047] figure 1 It is a schematic structural diagram of an induction cooker provided by an embodiment of the present invention. figure 2 for figure 1 The circuit diagram of the pot detection circuit in the induction cooker shown Figure one . Such as figure 1 As shown, the induction cooker provided in this embodiment includes a pot detection circuit 1, such as figure 2 As shown, the pot detection circuit 1 includes: a controller 11, an IGBT control circuit 12, and a resonance circuit 13 connected in sequence. The controller 11 controls the resonance circuit 13 through the IGBT control circuit 12 to generate two resonance signals. The device 11 obtains the above two resonance signals and detects whether there are pots on the induction cooker based on the two resonance signals. Further, the pot detection circuit 1 further includes: a current detection circuit 14 located between the controller 11 and the power supply 2 The controller 11 is used to determine whether the cookware o...

Abstract

The invention provides an induction cooker and a pot detection method. The induction cooker comprises a pot detection circuit. The pot detection circuit comprises a controller, an IGBT control circuit and a resonance circuit which are sequentially connected with one another, wherein the controller controls the resonance circuit through the IGBT control circuit so that the resonance circuit generates two paths of resonance signals, and the controller obtains the two paths of resonance signals and detects whether a pot is arranged on the induction cooker according to the two paths of resonance signals. The pot detection circuit further comprises a current detection circuit between the controller and a power supply; and the controller judges whether the pot is qualified according to the working current of the current detection circuit. According to the induction cooker and the pot detection method provided by technical schemes of the invention, the pot is detected through control signals sent by the controller and the current magnitude of the current detection circuit, and therefore, the accuracy of the detection of the pot can be ensured, the service life of the induction cooker can be prolonged, and the induction cooker will not be easily damaged during a subsequent use process.

Description

technical field [0001] The invention relates to the technical field of circuit structures, in particular to a detection method for an electromagnetic cooker and a pan. Background technique [0002] Induction cooker, also known as induction cooker, works on the principle of using high-frequency alternating current to pass through the coil plate to generate a high-frequency alternating magnetic field. When the alternating magnetic force line cuts the pot placed on the panel, an eddy current is generated at the bottom of the pot and quickly Heat, so as to achieve the purpose of heating the food in the pot. In view of the electromagnetic heating characteristics of the induction cooker, the pots suitable for the induction cooker must be made of iron or have a certain iron content, so that the induction cooker can work in a normal and stable state. Therefore, before using the induction cooker, it is necessary to detect whether a suitable pan is placed on the induction cooker. ...
