A half-bridge induction cooker pot detection method, device and half-bridge induction cooker

Abstract

The invention discloses a detection method and device of a half-bridge induction cooker pot. The method comprises the steps of gradually increasing the driving power of the induction cooker; obtainingrunning power of the induction cooker; judging whether the running power is larger than the first preset power value or deviation value of enabling the running power to be smaller than the driving power of the induction cooker is smaller than the second preset power value, wherein the first preset power value, the second preset power value and the running power is in positive correlation with thedriving power of the induction cooker; and when the running power is larger than the first preset power value, or the deviation value is smaller than the second preset power value, determining that the pot is placed on the induction cooker. Through gradual increasing of the driving power of the induction cooker and obtaining the running power, the running power is compared with the preset value,when the induction cooker is slowly heated, whether the pot is placed on the induction cooker or not is synchronously judged, the defects of pot hitting noise caused by a dedicated pot detection pulseand normal starting after waiting for a certain time can be overcome, the time when a user waits for induction cooker pot detection is saved, and the experience feeling of the user during use is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a half-bridge induction cooker pan detection method and device, and a half-bridge induction cooker. Background technique [0002] Induction cooker is a kind of high-efficiency and energy-saving kitchen utensils, which allows heat energy to be directly generated at the bottom of the pot without open flame or conduction heating, and the thermal efficiency is greatly improved. Induction cooker is a cooking utensil made using the principle of electromagnetic induction heating. It is composed of high-frequency induction heating coils, high-frequency power conversion devices, controllers, and ferromagnetic material pot bottom cookers. When in use, an alternating current is passed into the heating coil, and an alternating magnetic field is generated around the coil. Most of the magnetic force lines of the alternating magnetic field pass through the metal pot body, and a lar...
