Problems solved by technology

[0002] For household electrical appliances such as induction cookers, but during the process of production debugging and user use, due to factors such as grid instability or loose power cord plugs, the AC power of household appliances will be cut off instantaneously. Therefore, it is necessary to reduce the voltage rapidly in a short period of time, and in order to achieve a rapid reduction in voltage in a short period of time, it is necessary to determine whether a power failure occurs before reducing the voltage

Abstract

The invention provides a detection method, a detection device, household appliance and a computer readable storage medium. The detection method comprises the steps of acquiring an AD value corresponding to an output voltage of a switch power circuit according to a preset acquisition frequency when the household appliance is energized and runs, determining a difference value of the AD value relative to an energization AD threshold; and determining power failure of an AC input when the difference value is detected to be larger or equal to a preset power-failure detection threshold. According tothe detection method provided by the technical scheme of the invention, on one hand, the power-failure detection reliability is high; and on the other hand, damage to the household appliance by powerfailure is prevented, and the household equipment can be further prevented from being burnt due to power failure.

Description

technical field [0001] The present invention relates to the field of household electrical appliances, in particular to an AC input power failure detection method, an AC input power failure detection device, a household electrical appliance, and a computer-readable storage medium. Background technique [0002] For household electrical appliances such as induction cookers, but during the process of production debugging and user use, due to factors such as grid instability or loose power cord plugs, the AC power of household appliances will be cut off instantaneously. Therefore, it is necessary to reduce the voltage quickly in a short time, and in order to realize the rapid voltage reduction in a short time, it is necessary to determine whether a power failure occurs before the voltage reduction. Contents of the invention [0003] In order to solve at least one of the above technical problems, an object of the present invention is to provide a method for detecting AC input po...
