Electric cooker and its anti-overflow control device and anti-overflow control method

Abstract

The invention discloses an electric cooker, an anti-overflow control device and an anti-overflow control method thereof. The anti-overflow control method comprises the following steps: controlling theelectric cooker to perform heating operation with pre-set power-adjusting ratio and detecting steam foams generated by the electric cooker; controlling the electric cooker to stop heating if steam foams are detected and obtaining heating time of the electric cooker in the current power-adjusting period as well as calculating restoration power-adjusting ratio after the electric cooker stops heating according to heating time within the current power-adjusting period and pre-set power-adjusting ratio; and controlling the electric cooker with the restoration power-adjusting ratio to perform heating operation when the electric cooker stops heating for the set time T. Therefore, restoration heating power-adjusting ratio is calculated after the electric cooker stops heating on the basis of heating power-adjusting ratio of the electric cooker. In this way, the electric cooker is effectively prevented from overflowing. Food can be fully boiled during the cooking process of the electric cooker.

Description

technical field [0001] The invention relates to the technical field of cooking appliances, in particular to an anti-overflow control method for an electric cooker, an anti-overflow control device for an electric cooker and an electric cooker. Background technique [0002] Electric cookers in the related art, such as rice cookers, generally adopt two methods for anti-overflow control. One is to use low power to control the heating of the rice cooker, so as to ensure that the rice cooker does not overflow during the boiling stage, but it will cause insufficient boiling and affect the taste of the cooked food. The other is to detect whether the rice cooker overflows during the boiling stage by assembling an overflow detection device, and when it detects that the rice cooker is about to overflow, control the rice cooker to stop heating for a period of time, and then restore the original power for heating, which may cause soup. Risk of overflow due to delayed return of juice. ...
