Abstract
An appliance having an input device, a control, a motor, and an analog display is provided. The input device is employed to input a set point temperature. The control is operably coupled to the input device and receives the set point temperature from the input device. The motor is operably coupled to the control and receives instructions from the control based on the set point temperature. The analog display is operably coupled to the motor. The analog display is driven by the motor to temporarily display the set point temperature and then to display a current temperature as the current temperature increases toward the set point temperature.
Claims10
An appliance comprising:
- an input device for inputting a first set point temperature for a cooking chamber and a second set point temperature for a probe thermometer;
- a thermostatic control operably coupled to the input device, the control receiving the first and second set point temperatures from the input device;
- a stepper motor operably coupled to the control, the stepper motor receiving instructions from the control based on the first and second set point temperatures;
- and
- an analog display operably coupled to the stepper motor, the analog display driven by the stepper motor to temporarily display one of the first and second set point temperatures and to alternatively display a cooking chamber current temperature as the cooking chamber current temperature increases toward the first set point temperature and a probe thermometer current temperature as the probe thermometer current temperature increases toward the second set point temperature.
A method of monitoring cooking temperatures, the method comprising the steps of:
- entering a first set point temperature;
- temporarily displaying the first set point temperature;
- entering a second set point temperature;
- temporarily displaying the second set point temperature;
- and
- alternatively displaying a first current temperature as the first current temperature rises toward the first set point temperature and a second current temperature as the second current temperature rises toward the second set point temperature on a single display configured to display either of the first current temperature or the second current temperature.
