    Abstract: A rice cooker includes an interlock that prevents the user from sliding the cooking pot out of the cooker without first disengaging internal assemblies that would otherwise be damaged. The rice cooker operates in any of three user selectable modes: a fully automatic mode in which the rice cooker measures out a user selected quantity of internally stored raw, unwashed rice, washes the rice, cooks the rice and then keeps the rice warm; a cook and keep-warm in which the cooking pot of the rice cooker is loaded with premeasured and washed rice from an external source and the rice cooker cooks the rice and keeps it rice warm; and a rice warming mode in which the cooking pot is loaded with already cooked rice and maintains it at a serving temperature. A startup routine checks that a pot is installed, that a lid is on the pot, that an upper pot cover assembly is at a required height, that a platform is in its latched position, and that a washer container is in its stowed position.

  • Patent number: 4170932
    Abstract: An electronic control for controlling the degree of toasting of a bread slice in a toaster. The control includes a thermocouple located within the passage of the toaster for the bread slice and responsive to the temperature of the toaster casing, the slice of bread and the air temperature within the passage to produce a voltage proportional to the resultant temperature. This voltage is integrated and actuates an electronic pulse generator with an adjustable pulse width which produces a triggering pulse. This pulse is used to actuate a solenoid which unlatches the support for the bread slice. The operational amplifier has a predetermined output voltage of reference defining the threshold of operation of the pulse generator. The electronic control is very stable and, therefore, produces uniform toasting, since it integrates the time required to obtain the desired degree of toasting as a function of the temperature variation to which the bread slice is subjected.

An indicator having respective weight scales corresponding to different kinds of meat is coupled with a selector and the timing member for setting the latter to correspond to the weight and type of meat to be cooked.

  • Patent number: 3938498
    Abstract: In apparatus for deep fat frying, control circuitry is provided for regulating the temperature of heating elements. During cooking the heating elements are immersed in cooking fluid and are maintained at a selected temperature by an operating thermostat. Two high limit thermostats are provided to turn off the heaters if the temperature exceeds a predetermined safe limit. For cleaning, the heating elements are raised out of the cooking fluid and automatically disconnected from the operating and first high-limit thermostats. The heaters are cyclically actuated and deactuated by a thermal time delay relay, to gradually raising the heater temperature to achieve pyrolytic cleaning of the heating elements. The second high-limit thermostat turns off the heating elements when a predetermined temperature is reached, ending pyrolytic cleaning.
