Abstract

An oven using radiant heat at infrared wavelengths optimized for producing rapid and uniform cooking of a wide variety of foods. The infrared oven toasts, bakes, broils, and reheats food at a much faster speed while maintaining high quality in taste and appearance of the cooked food. Optimal infrared wavelengths of the radiant heat sources are used for the best balance of cooking performance, while also reducing the time required to cook the food. Typically short to medium wavelength infrared radiant energy will result in good performance for toasting and browning of food. Medium to long wavelength infrared radiant energy is well suited for delivering more deeply penetrating radiant energy into the food. This deep penetration of radiant infrared heat energy results in a more thorough internal cooking of the food than with conventional methods of conduction and convection cooking.

Claims (29)

1. A method for cooking a food with infrared radiant heat, said method comprising the steps of:

cooking a food located in an oven chamber with radiant heat at a first infrared wavelength emitted from at least one first infrared heater located on one side of the food; and

radiant heat at a second infrared wavelength from at least one second infrared heater located on another side of the food; wherein:

at least one of the first infrared heater and the second infrared heater comprises an electrically conductive filament inside of a quartz glass tube; and

the quartz glass tube comprises at least one of:

a quartz glass tube chemically etched so as to pass at least one of the first infrared wavelength and the second infrared wavelength from the electrically conductive filament; and

a quartz glass tube having extruded grooves therein so as to pass at least one of the first infrared wavelength and the second infrared wavelength from the electrically conductive filament.

2. The method of claim 1 , wherein the second infrared wavelength is longer than the first infrared wavelength.

3. The method of claim 2 , wherein the radiant heat at the second infrared wavelength penetrates deeper into the food than the radiant heat at the first infrared wavelength.

4. The method of claim 2 , wherein the radiant heat at the second infrared wavelength evaporates the moisture from the food faster than the radiant heat at the first infrared wavelength.

5. The method of claim 2 , wherein the radiant heat at the second infrared wavelength more deeply cooks the food faster than the radiant heat at the first infrared wavelength.

6. The method of claim 2 , wherein the radiant heat at the first infrared wavelength browns the food surface.

7. The method of claim 1 , further comprising the step of defrosting the food with the radiant heat.

8. The method of claim 1 , further comprising the steps of:

reflecting radiant heat from the at least one first infrared heater onto the food with a first radiant heat reflector; and

reflecting radiant heat from the at least one second infrared heater onto the food with a second radiant heat reflector.

9. The method of claim 8 , wherein the infrared wavelengths of the reflected radiant heat are longer than the infrared wavelengths from the first and second infrared heaters.

10. The method of claim 1 , further comprising the step of reflecting radiant heat from the radiant heat reflectors onto the food at a third and fourth plurality of infrared wavelengths.

11. The method of claim 1 , further comprising the step of emitting radiant heat from the at least one first infrared heater onto the food at a first plurality of infrared wavelengths.

12. The method of claim 1 , further comprising the step of emitting radiant heat from the at least one second infrared heater onto the food at a second plurality of infrared wavelengths.

13. The method of claim 1 , wherein the first infrared wavelength is selected for substantially optimum browning of the food.

14. The method of claim 1 , wherein the second infrared wavelength is selected for substantially optimum internal cooking of the food.

15. The method of claim 1 , wherein the first infrared wavelength is from about 1 to about 3 microns.

16. The method of claim 1 , wherein the first infrared wavelength is from about 1.5 to about 2.5 microns.

17. The method of claim 1 , wherein the first infrared wavelength is about 1.63 microns.

18. The method of claim 1 , wherein the second infrared wavelength is about 2.11 microns.

19. The method of claim 1 , wherein the first infrared wavelength comprises a first plurality of infrared wavelengths.

20. The method of claim 1 , wherein the second infrared wavelength comprises a second plurality of infrared wavelengths.

21. The method of claim 1 , further comprising the step of providing a user interface having cooking routines stored for selection by a user when cooking a respective food.
