Cooking utensil control method and device, and cooking utensil

Abstract

The invention provides a cooking utensil control method and device, and a cooking utensil. The control method comprises steps that after the cooking utensil is electrified to operate, environment parameters of the cooking utensil detected by a sensor are acquired according to preset frequency; values of the acquired environment parameters are acquired, an on-off plan of a relay is determined according to the parameter values to control state change of the relay according to the on-off plan; when the relay starts operation according to the on-off plan, the on-off plan is not updated, timing isfurther carried out, after the operation period is over, the on-off plan is updated according to the parameter values; the on-off plan at least comprises the on-off duty ratio information and the period information of the relay during the subsequent operation period. The control method is advantaged in that locking of a relay control module and fine tuning control on the locking period and a relayon-off ratio in the operation process are realized, precise control in the product operation process is guaranteed, and reduction of service life of products caused by thermal agitation is avoided.

Description

Technical field [0001] The present invention relates to the technical field of intelligent cooking, in particular to a method for controlling a cooking appliance, a control device for a cooking appliance, and a cooking appliance. Background technique [0002] In recent years, people have paid more and more attention to healthy life, and more and more requirements for the functions that can be realized by home appliances. The popularity of ovens and cooking products with steam mixing function has also increased year by year, especially in recent years, such products The sales of the company have been increasing by more than 50% every year. [0003] With the increase in the application coverage of cooking products, cheap smart cooking products that can automatically adjust their cooking parameters according to application requirements have also appeared. Products such as small ovens are also changing from the original mechanical oven to a large area with temperature. The intelligent...

Problems solved by technology

For example, if a program requires an on-off ratio of 10 seconds on and 20 seconds off when the temperature is greater than 160°C, and an on-off ratio of 15 seconds on and 15 seconds off when the temperature is less than 160°C, then when the temperature of the cooking cavity reaches 160°C , especially when the program’s on-off control of the relay is between the 11th second and the 15th second, due to thermal disturbance, the chip will output frequent on-off signals to the relay, making the relay frequently on-off during this time period. Worst case, if this happens during any control cycle, the life of the relay will be exhausted in tens of hours
