Abstract
A steam exhaust system of an electric pressurizing device which can control the pressure in a cooking vessel and simultaneously can prevent the pressure in the cooking vessel from excessively increasing during the cooking operation. In the steam exhaust system, a steam exhaust pipe penetrates a lid of the electric pressurizing device, and has a steam exhaust channel formed therein. A valve assembly is provided which includes a frame and a pressurizing plate. The valve assembly opens and closes the steam exhaust channel of the steam exhaust pipe by the pivoting of the pressurizing plate. A pressure control device actuates the valve assembly by way of a magnetic force to control the blocking pressure in the steam exhaust pipe.
