Door control method and circuit and kitchen electrical equipment

The invention discloses a door control method and circuit and kitchen electrical equipment. The door control method comprises the steps that when the kitchen electrical equipment is powered on for the first time, the highest running speed of a rotating door is set; the rotating door is controlled to automatically run for the preset number of times at the highest running speed, and the running period time is recorded, wherein automatic running comprises automatic door opening and automatic door closing; according to the highest running speed and the running period time, the door opening stroke and the door closing stroke are calculated; and the door opening stroke and the door closing stroke are compared, and if the door opening stroke and the door closing stroke are consistent, when the rotating door is opened or closed again, the motor speed of a motor used for controlling running of the rotating door is linearly and dynamically adjusted. According to the scheme, the functions of self-adaptive memory of the
