FOOD PROCESSOR AND COOKING CONTROL METHOD AND APPARATUS THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/024190
Kind Code:
A1
Abstract:
A food processor and a cooking control method and apparatus thereof. The cooking control method comprises the following steps: detecting a zero crossing signal of an alternating current inputted into a motor (50) (S1); obtaining a zero crossing point of the alternating current according to the zero crossing signal, and outputting a start pulse signal to a triac module (10) after a delay of a first preset time T1 from the zero crossing point, and outputting one start pulse signal to the triac module (10) every second preset time T2 (S2); detecting a magnetic field converting signal provided by a magnet ring (302) so as to output an alternating level signal, and obtaining a rotation speed V of the motor (50) by using a periodic speed measurement method according to the alternating level signal (S3); and adjusting the first preset time T1 according to the rotation speed V of the motor (50) so as to control the motor (50) to run in a low and constant speed, thereby driving a stirring component (60) to stir the cooked food in a cooking process of the food processor (S4). The motor (50) can run in a low and constant speed by changing the conducting time of the triac module (10) of the motor (50), so as to stir the food in the cooking process, and prevent the food processor from being burnt in the bottom.
