Fault detection method and control method of electric cooker and its anti-overflow detection circuit

Abstract

The invention discloses an electric cooling device and a fault detection method and control method of an anti-overflow detection circuit of the electric cooling device. The fault detection method comprises the following steps that the present state of the electric cooling device is determined, and whether the anti-overflow detection circuit outputs a fault signal is detected; if the present state of a standby state and the fault signal output by the anti-overflow detection circuit is received continuously within preset time T1, it is determined that the anti-overflow detection circuit has a fault; and if the present state is a working state and the duration time of the received fault signal output by the anti-overflow detection circuit is greater than preset time T2, it is determined that the anti-overflow detection circuit has a fault, and the preset time T2 is greater than the preset time T1. When the anti-overflow detection circuit has a fault can be detected according to the operation state of the electric cooking device, normal cooking of the electric cooling device is ensured, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a fault detection method for an overflow detection circuit in an electric cooker, a control method for the electric cooker 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 art cannot determine whether the anti-overflow detection circuit is faulty. [0003] In addition, in related technologies, when the anti-overflow detection circuit fails, the electric cooker does not perform corresponding parameter adjustment, and the electric cooker cannot continue to work, thereby seriously affecting the normal cooking effect and subsequent use. [0004] In summary, related technologies need to be improved. Contents of the...
