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

Abstract

The invention discloses an electric cooker and an anti-overflow control device and method thereof. The anti-overflow control method includes the steps that after the electric cooker enters a boiling stage, the electric cooker is controlled to conduct heating at a preset power regulation ratio, and steam foam generated in the cooking process of the electric cooker is detected through a foam detection device; when the detection device detects the steam foam, at least two different power regulation ratios are acquired, and the electric cooker is controlled to conduct alternate heating according to the power regulation ratios to prevent the electric cooker from overflowing and ensure full boiling in the electric cooker. By means of the electric cooker and the anti-overflow control device and method thereof, at least two different power regulation ratios can be adopted for alternately controlling the electric cooker to continue working when the foam detection device detects the steam foam,and therefore the electric cooker can be effectively prevented from overflowing and full boiling in the food cooking process of the electric cooker can also be ensured.

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 electric rice cooker overflows during the boiling stage by assembling an overflow detection device, and when detecting that the electric rice cooker overflows, control the electric rice cooker to stop heating for a period of time, and then restore the original power for heating. If the time is too long, it will also lead to insufficient ...
