Electric cooking device and anti-overflow control device and method thereof

Abstract

The invention discloses an electric cooking device and an anti-overflow control device and method thereof. The anti-overflow control method includes the following steps that after the electric cookingdevice enters the boiling stage, the electric cooking device is controlled to carry out heating work at the preset power adjusting ratio, and steam foam generated when the electric cooking device cooks is detected; if the steam foam is detected, heating time of the electric cooking device in a current power adjusting period is obtained, and according to the heating time of the electric cooking device in the current power adjusting period and the preset power adjusting ratio, stopping heating time T after the electric cooking device is overflowed is computed; the electric cooking device is controlled to stop heating, and when the stopping heating time of the electric cooking device reaches the T, the electric cooking device is recovered and controlled to carry out heating work at the poweradjusting ratio, and therefore the stopping heating time when the electric cooking device is about to overflow can be computed based on the heating power adjusting ratio of the electric cooking device; the overflow phenomenon of the electric cooking device can be prevented, and full boiling when the electric cooking device cooks foods can also be guaranteed.

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 is detected that the rice cooker is about to overflow, control the rice cooker to stop heating, and the time for each stop of heating is fixed. It will also cause insufficient boiling and affect the taste of cooked food. [0003] There...
