Cooking utensil and control method thereof

The cooking utensil comprises a cavity and a steam generator, a cooking cavity and a steam deceleration cavity are defined in the cavity, the steam deceleration cavity is located above the cooking cavity, the bottom of the steam deceleration cavity is communicated with the cooking cavity, and exhaust holes are formed in the lower ends of at least two side walls of the cooking cavity and/or at least two sides of the bottom wall of the cooking cavity. The steam generator is arranged outside the cavity, and the steam outlet end of the steam generator is communicated with the steam speed reduction cavity. Air in the cooking cavity can be emptied through the exhaust holes, and steam in the cavity is used for steaming food. According to the cooking utensil, the steam speed reduction cavity and the exhaust hole are formed in the upper end and the lower end of the cooking cavity respectively, the air mixing amount in steam can be reduced, and therefore the steaming temperature of food is increased, the steaming time
