Cooking control method and cooking control device, and cooking equipment

Abstract

The invention provides a cooking control method, which comprises the following steps: detecting whether a first temperature in cooking equipment reaches a first preset temperature or not when the cooking equipment is started up; controlling and dividing a preset heating time into a plurality of heating stages when the first temperature reaches the first preset temperature, and implementing a heating operation on the cooking equipment under control in each heating stage in accordance with preset heating parameters; acquiring a second temperature in the cooking equipment after executing the heating operation on the cooking equipment by the preset heating time; and confirming whether it needs to continue the heating operation on the cooking equipment or not in accordance with a valuing rangeof the second temperature, so that temperature in the cooking equipment is kept at a target temperature. Correspondingly, the invention also provides a cooking control device and the cooking equipment. According to the technical scheme, temperature changes in the cooking equipment can be effectively controlled in a mode of piecewise control of heating; and production equipment of the cooking equipment can be reduced, and service life can be prolonged.

Description

technical field [0001] The present invention relates to the technical field of cooking equipment, in particular, to a cooking control method, a cooking control device and cooking equipment. Background technique [0002] With the continuous improvement of the quality of life, users have more and more stringent requirements for diet. Due to the characteristics of environmental protection and convenient use, the electric oven is accepted by more and more families. The heating principle of the electric oven is to make the resistance wire (rod) energized and heated, so that the electric energy becomes heat energy, so that the temperature in the box increases, and then the food is baked until cooked. The temperature in the box is controlled, and the performance of the temperature control directly affects the quality of the food baked in the oven. [0003] At present, the existing temperature control methods for oven heating mainly include threshold control method and PID control...

AI Technical Summary

Problems solved by technology

[0004] The thermistor is set on the edge of the cavity. During the heating process, due to the hysteresis effect of heat conduction, the temperature of the thermistor is different from the temperature of the center of the box during the heating process, and the relationship between the two is nonlinear. Therefore, using the threshold control method to control the relay for heating may easily lead to excessive overshoot and long oscillation time, which will lead to problems such as poor heating effect; using the PID method to control the relay for heating requires frequent switching of the relay, which will seriously reduce The life of the relay, while using the PID method to control the thyristor for heating, the cost is too high
