Abstract

The invention discloses an electrical device and a method for detecting that a mechanical timer is stuck, wherein the electrical device includes: a mechanical timer, the mechanical timer includes a plurality of gears; The feedback signal of any gear; the control device is used to judge whether the mechanical timer is stuck according to the feedback signal, and to control the load of the electrical equipment to stop working when the mechanical timer is stuck. The electrical equipment of the present invention can effectively solve the problem that the whole machine catches fire caused by the continuous operation of the mechanical electrical equipment when the timer is stuck, thereby causing the user's personal safety or property loss.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an electrical equipment and a method for detecting that a mechanical timer is stuck. Background technique [0002] A mechanical microwave oven refers to a microwave oven that is purely mechanically controlled without a computer board. In a mechanical microwave oven, the microwave generator works according to the set time and power after the time is selected by the time knob on the timer and the power is selected by the power knob. [0003] The defective rate of timers in mechanical microwave ovens is about 17PPM per year. Although it is not high, it is quite harmful. The failure of the timer is mainly due to the disconnection of the motor winding, the friction between the debris after the cracking of the motor magnet and the motor stator, foreign objects attached to the gear, and the disconnection of the solder joints of the motor winding. If the microwave oven con...
