Problems solved by technology

In the heating stage when the rice cooker cooks rice, the rice water in the pot does not boil and will not overflow. If overflow is detected at this time, the rice cooker will be controlled to stop heating, which will not only greatly affect the cooking effect, but also affect the taste of the cooked rice. Unable to complete the cooking smoothly, affecting the user's use

Abstract

The invention discloses an electric cooker and its anti-overflow fault detection device and anti-overflow fault detection method, wherein the anti-overflow fault detection method includes the following steps: after the electric cooker enters the heating stage, detect the electric cooker in real time. the temperature in the cooker, and detect the steam bubbles generated when the electric cooker is cooking through the bubble detection device; if the steam bubbles are detected, generate a foam detection signal, and obtain the duration of the foam detection signal; when If the duration of the foam detection signal is less than the first preset time and the current temperature in the electric cooker is less than the preset boiling point temperature, it is judged that the electric cooker has a false trigger of the anti-overflow detection, so as to avoid false triggering. The cooking effect of the resulting electric cooker is poor, which fully meets the needs of users.

Description

technical field [0001] The invention relates to the technical field of cooking appliances, in particular to an anti-overflow fault detection method of an electric cooker, an anti-overflow fault detection device for an electric cooker and an electric cooker. Background technique [0002] When an electric cooker in the related art, such as an electric rice cooker, detects overflow, it triggers the electric cooker to stop heating, and the time for each stop of heating is fixed. In the heating stage when the rice cooker cooks rice, the rice water in the pot does not boil and will not overflow. If overflow is detected at this time, the rice cooker will be controlled to stop heating, which will not only greatly affect the cooking effect, but also affect the taste of the cooked rice. The cooking cannot be completed smoothly, which affects the user's use. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned te...
