Electric cooker and its overflow prevention heating control method and device

Abstract

The invention discloses an electric cooker, an anti-overflow heating control method and device thereof. The anti-overflow heating control method comprises the following steps: through a foam detectiondevice, detecting steam foams generated during the cooking process of the electric cooker after the electric cooker enters a boiling phase; if steam foams are detected, controlling the electric cooker to stop heating, obtaining time spent in continuously detecting foams by the foam detection device and calculating heating-restoration power after the electric cooker stops heating according to thetime spent in continuously detecting foams by the foam detection device; and controlling the electric cooker to perform heating operation at the heating-restoration power when the electric cooker stops heating for the set time T1. Accordingly, food cooked in the electric cooker is fully boiled under the premise that the electric cooker is effectively prevented from overflowing.

Description

technical field [0001] The invention relates to the technical field of cooking appliances, in particular to an electric cooker and its anti-overflow heating control method and device. Background technique [0002] In the related art, when the anti-overflow control of an electric cooker (such as an electric rice cooker), an anti-overflow detection device is installed to detect whether the electric cooker overflows during the boiling stage, and when it is detected that the electric cooker is about to overflow, the electric cooker is controlled to stop heating for a period of time, and then When heating is resumed, the time to stop heating is usually fixed, and the heating power used when resuming heating is also the same as the heating power before stopping heating. [0003] Wherein, when the rice cooker cooks rice, in order to cope with different rice water grades, the above-mentioned stop heating time is generally set longer, which will reduce the continuous boiling time of ...

AI Technical Summary

Problems solved by technology

[0003] Wherein, when the rice cooker is cooking rice, in order to cope with different rice water levels, the above-mentioned stop heating time is generally set longer, which will reduce the continuous boiling time of the cooking food, resulting in insufficient boiling of the cooking food and affecting the taste of the cooking food

And then restore the original power for heating, which may cause the soup to not return in time and cause the risk of overflow
