Abstract

The invention relates to an oven heating tube fault detection circuit and an oven. The number of heating tubes is two or more. The oven heating tube fault detection circuit comprises a current detection assembly and a control chip, wherein the control chip is connected with a control part of a control switch in each heating tube, the current detection assembly is connected with one end of a controlled part of the control switch in each heating tube, an external power supply and the control chip, and the other end of the controlled part of the control switch in each heating tube is connected with a corresponding load; and the current detection assembly detects the current transmitted to each heating tube, the control chip analyzes whether each heating tube has a fault according to the on-off state of the control switch in each heating tube and the current detection signal sent by the current detection assembly, and the fault can be found in time when the heating pipe has the fault, so that the food baking effect is prevented from being affected by faults of the heating tubes, and the use reliability of the oven is improved.

Description

technical field [0001] The present application relates to the technical field of electrical equipment, in particular to an oven heating pipe fault detection circuit and an oven. Background technique [0002] With the development of science and technology and the continuous progress of society, more and more electrical appliances appear in people's daily work and life, and the way of using an oven to bake food is also loved by more people. [0003] In a traditional oven, after the user sets the heating temperature, the controller controls some or all of the heating tubes to work according to the set heating temperature to bake the food placed in the oven. However, if the failure of the heating tube of the oven is not found in time, it will directly affect the baking effect of the food and reduce the reliability of the oven. Contents of the invention [0004] Based on this, it is necessary to provide an oven heating tube failure detection circuit and an oven for the low rel...
