  • Patent number: 6578469
    Abstract: A digital frying pan provides temperature and/or food doneness information associated with food cooked within the pan. A thermal sensor coupled with the pan senses temperature and generates corresponding signals, and processing electronics coupled with the sensor convert the signals to data for display on a LCD. A warning buzzer or LED warns the user of completed cooking. The frying pan may be programmed to desired food types or personal temperatures or food doneness options. The invention also provides a remote sensing food doneness system for remotely viewing and then determining food temperature and/or food doneness. The remote system uses thermal imaging optics and thermal sensing techniques to remotely sense food temperature. Preferably a second optical element images the food onto a CCD to display an image of the food to a user. The system is mounted by a user who views the CCD to ensure appropriate placement in line of sight from the food.

  • Patent number: 6283015
    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.

  • Patent number: 6274850
    Abstract: The invention is directed to an apparatus for identifying a subject medium from several possible subject media within a cooking device, such as deep fat fryer. The apparatus contains one subject medium within the cooking device and has a controller, which includes a timer, and generates a conductivity signal. The apparatus also includes a conductivity measuring device which receives the conductivity signal and measures a conductivity value device in response to the conductivity signal. The controller determines the subject medium's composition by comparing the measured conductivity value to predetermined conductivity values for the known group of subject media.
