Abstract

The invention discloses an electric cooker and a power-on anti-overflow detection circuit fault detection method of same; the method comprises the following steps: start timing when the electric cooker is powered; determining whether a trigger signal outputted by the anti-overflow detection circuit is received or not when the time reaches a first preset time; determining the anti-overflow detection circuit has failed if the trigger signal is not received. The novel method can automatically determine whether the anti-overflow detection circuit has failed or not when the electric cooker is powered up, thus ensuring normal cooking of the cooker, and improving user experiences.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a fault detection method for an overflow prevention detection circuit when an electric cooker is powered on and an electric cooker. Background technique [0002] In the related electric cooker with anti-overflow function, when the anti-overflow detection circuit breaks down, the anti-overflow function fails, which may cause serious consequences that the electric cooker cannot work normally. However, the related technology cannot judge whether the anti-overflow detection circuit is faulty, and needs to be improved. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a fault detection method for the anti-overflow detection circuit when the electric cooker is powered on, and the method can automatically detect ...
