Abstract

The invention discloses a control method of a cooking utensil and the cooking utensil. The cooking utensil comprises an air pump used for inflating a cooking space of the cooking utensil. The control method comprises the steps that the temperature T in the cooking space of the cooking utensil is collected, when the temperature T is larger than or equal to the preset temperature value T1, a first PWM signal is sent to a motor of the air pump to start the motor of the air pump, and in the starting stage of the motor, the duty ratio of the first PWM signal is gradually increased. Therefore, the duty ratio of the first PWM signal is gradually increased, the starting of the motor is soft starting, the starting voltage of the motor can be gradually increased from 0, and the service life of the motor is prolonged; the starting of the motor is soft starting, the starting rotating speed of the motor can be gradually increased from 0, and the service life of the motor is prolonged.

Description

technical field [0001] The present invention relates to the field of cooking appliances, in particular to a control method of the cooking appliance and the cooking appliance. Background technique [0002] The current fast cooking appliance uses an air pump to fill the cooking space with cold air to prevent the pot from overflowing, and can heat quickly with high power. The motor of the air pump is electrically connected to the controller, and the controller controls the operation of the motor of the air pump, and then controls the operation of the air pump. And when the motor of the air pump is started, the controller controls the air pump to directly rotate at the optimum operating speed, so that the starting speed of the motor is large and the starting voltage of the motor is high. In this way, the loss of the motor is large, and the service life of the motor is short. [0003] Therefore, the present invention provides a cooking appliance control method and the cooking a...
