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.
Claims7
A steam exhaust system of a pressurized cooking device which comprises:
- a steam exhaust pipe extending from the cooking device;
- a valve assembly including a frame member and a pressurizing plate, said frame member being assembled with the steam exhaust pipe, said pressurizing plate having a first end pivotally assembled with an upper end of the frame member and a second end detachably fitted to close on an upper end of the steam exhaust pipe, the valve assembly opening and closing the steam exhaust pipe by a pivoting of the pressurizing plate;
- and
- a pressure control means for actuating the valve assembly utilizing a magnetic force to control the blocking pressure in the steam exhaust pipe.
A steam exhaust system for use in a cooker having a cooking vessel, the system including a steam exhaust channel adapted to exhaust steam from the cooking vessel, and an electromagnet adapted to open and close the steam exhaust channel for adjusting the steam pressure in the cooking vessel, wherein the opening and closing of the steam exhaust channel by the electromagnet is controlled by controlling the current applied to the electromagnet in a continued fashion during a cooking process, so that a steam flow resistance in the steam exhaust channel is controlled.
A steam exhaust system for a pressurized cooking device which comprises:
- a steam exhaust channel extending from the cooking device;
- a valve assembly connected to the cooking device, said valve assembly containing a pressurized plate for opening and closing the steam exhaust pipe in response to the pressure within the cooking device;
- and
- a pressure control system for selectively regulating the pressure within the cooking device, said pressure control system including an electromagnet for generating a magnetic force, said electromagnetic means being operatively associated with the pressurizing plate.
