Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] refer to Figure 1 to Figure 4 , a method for controlling the cooking state of an electromagnetic cooker based on a micro-acceleration sensor. In the electromagnetic cooker body 1, below the contact position of the pot body 4 and the ceramic glass plate 3, the ceramic glass plate is close to the side of the furnace body, and one or equally divided along the circumference Several micro-acceleration sensor chips 2 are positioned to detect the vibration signal transmitted from the pot body 4 to the ceramic glass plate 3 . When using the induction cooker, the pot body filled with food and water is placed on the ceramic glass panel, the power is turned on, and the pot body 4 is heated by the induction coil 6 . During the heating process, the vibration of the ceramic glass plate 3 is monitored in real time through the micro-acceleration sensor chip. The tested vibrat...

Abstract

A micro acceleration transducer-based cooking state control method for an electromagnetic oven boiler is realized as follows: a micro acceleration transducer chip detects a vibration signal transmitted by a boiler body to a ceramic glass plate; during the heating processing, an electromagnetic oven monitors the vibration of the ceramic glass plate through the micro acceleration transducer in real time; in case that the current vibration acceleration exceeds a preset vibration acceleration threshold value, the judgment of boiler body boiling state at present can be made, otherwise, the judgment of boiler body un-boiling state at present can be made; when the judgment of boiler body boiling state at present is made, a first time meter is started to record the heating time; when the heating time reaches a preset heating time value, the main power source is switched off, the electromagnetic oven stops heating temporarily, and a second time meter is started to record the heating suspension time; when the heating suspension time achieves a preset suspension time value, the main power source of the electromagnetic oven is restarted to heat the boiler body; as a result, the control on the cooking states is realized. The method improves the accuracy and eliminates the time lag.

Description

technical field [0001] The invention relates to a method for controlling the cooking state of an electromagnetic cooker. Background technique [0002] With the improvement of living standards, home users gradually accept safe and hygienic cooking utensils, and induction cookers have entered thousands of households. The induction cooker uses the principle of electromagnetic induction to heat food. The furnace surface of the induction cooker is a heat-resistant ceramic plate. The alternating current passes through the coil under the ceramic plate to generate a magnetic field. When the magnetic field lines in the magnetic field pass through the bottom of the iron pot or stainless steel pot, an eddy current is generated, which makes the bottom of the pot heat up rapidly and achieves the purpose of heating food. the goal of. The heat at the bottom of the pot body is conducted to the ceramic glass cooktop. The existing induction cooker basically uses a thermistor installed at th...
