Definitions

  • a "Humidity” control 44 to set a predetermined humidity in the microwave oven heating cavity 30
  • a "Turn Food Over” control 45 to indicate that the food is to be turned over
  • a "Time Out” control 46 to indicate that the door 12 is to be closed after turning food over after a predetermined time has elasped
  • a "Done” control 47 to indicate internal doneness of the food are positioned on the control panel 14.
  • Figure 3 illustrates a side and top perspective view of the microwave oven 10 with a portion of the housing wrap 18 removed and illustrating a cutaway portion of the ventilation hood 42 showing the top side 20 and the right side 22 of the housing wrap 18, the door 12, the control panel 14, the push bar door release handle 16, the upper hinge 26, the exterior side of the exit ventilation port 36 of the microwave heating cavity 30, the humidity sensor 32 and the temperature sensor 34, both shown in imaginary lines, positioned adjacent to and by the exterior side of the plurality of exit ventilation port holes 36 and connected to the programmable controller 40, the magnetron 50, the waveguide 52, and the mode stirrer 54 driven by the mode stirrer motor 56.
  • Figure 6 illustrates a top enlarged and expanded view of the humidity sensor 32 and the temperature sensor 34 as shown in Figure 5 positioned adjacent to and by the plurality of exit port ventilation holes 38 in the top of the microwave heating cavity 30 with the top 20 of the housing wrap 18 and the ventilation hood 42 partially cutaway. All other numerals correspond to those elements previously described.
  • the slope of the third segment 98 of the three segment piecewise linear curve from point 102 to 104 is equilibrium occuring of the surface temperature of the food.
  • the characteristic humidity curve 92 plateaus at point 104 indicating that the surface temperature of the food has reached equilibrium of one hundred degrees centigrade. While the peaked out plateau portion of the curve 92 is represented as a smooth curve, in reality there are "noise-like" perturbations on the curve due to surface boiling of water of the food. Any point on the characteristic humidity curve 92 is indicative of the surface temperature of the food while the integral of the area under the curve 92 at that point is indicative of the "internal doneness" of the food being cooked in the microwave oven heating cavity 30.
  • Each particular type of food has its own individual "characteristic humidity curve” and the food during microwave cooking follows the characteristic humidity curve for that particular food.
  • the programmable controller 40 is also programmed to make electronic decisions as to increasing or decreasing the air exchange rate of the air exchange control circuit 90 which consists of the fan 58; increasing or decreasing the microwave power source duty cycle, in this example, the magnetron control circuit 88, or; increasing or decreasing the incoming air temperature such as controlling preheating of the incoming air temperature with an infrarec lamp or by passing the air over a resistance heater such as a Calrod.
  • the programmable controller 40 can be selected for the type of food being cooked in the microwave oven 10 through the numeric inputs on the numeric keyboard control panel 14.
  • This control panel contains numeric input operator feature: in addition to the standard microwave oven control panels currently on the market such as a "Humidity” control 44, a "Turn Food Over” control 45, a “Time Out” control 46 and a “Done” control 47.
  • the "Humidity” keyboard control 44 permits the input of the humidity cooking parameter for the selected cooking algorithm stored in the programmable controller 40.
  • the programmable controller 40 also indicates to the cook when the optimum time is reached to turn a food over such as meat and activates a "Turn Food Over” control 45 such as illuminating a control light as well as sounding an audible alarm. This point occurs where the characteristic humidity curve 92 of Figure 9 reaches peak absolute humidity h at point 104 as determined by the programmable controller 40. If the cook fails to close the door 12 within a predetermined time as determined by the programmable controller 40 after turning the food over, the "Time Out” control 46 such as an illuminated control light as well as an audible alarm are activated by the programmable controller 40. The programmable controller also indicates to a cook when the food is done by activating the "Done” control 47 such as illuminating a control light as well as sounding an audible alarm.
  • a "Turn Food Over” control 45 such as illuminating a control light as well as sounding an audible alarm.
