Abstract

The embodiment of the invention discloses a micro-wave oven control method, micro-wave oven control equipment and a micro-wave oven. The method comprises the following steps: receiving a sampling interruption signal generated by a digital signal of the current food temperature and a digital signal of the current food humidity according to a pre-set period; responding to the sampling interruption signal, calculating the current food temperature , the current food humidity and the received setting temperature to obtain the amount of digital control according to a fuzzy PID (proportion integration differentiation) algorithm, and performing digital to analog conversion and PWM (pulse-width modulation) on the amount of digital control to obtain an analog pulse control signal; utilizing the analog pulse control signal to control the input power of a magnetron; and circulating the process until the current temperature reaches the setting temperature. According to the invention, through the closed-loop control method for continuously acquisition, calculation and output, the precision for temperature control is increased; and meanwhile, a user can obtain a pre-set heating effect without setting the heating time and heating manner of food according to experience, so that the convenience for use is further improved.

Description

technical field [0001] The present invention relates to the technical field of microwave oven control, and more specifically, relates to a microwave oven control method, control equipment and a microwave oven. Background technique [0002] A microwave oven is a modern cooking stove that uses microwaves to heat food. The microwave oven is composed of a power supply, a magnetron, a control circuit, a cooking cavity and a waveguide, etc., and the waveguide transmits the microwave power generated by the magnetron to the cavity in the control circuit to heat food. [0003] The existing microwave oven control method is based on the user entering heating parameters such as cooking time, food type and weight on the operation panel for different foods, and the user continuously explores to achieve a more suitable heating temperature. [0004] Therefore, the existing microwave oven control method has the technical defects of poor heating control precision and inconvenient use. Cont...
