Abstract

There is provided an indoor/outdoor tabletop grill appliance which uses quartz halogen tubes as radiant heating elements to provide cooking functionality combined with the aesthetics of the outdoor grilling experience. The invention provides the advantage of various forms of cooking that also speed up the cooking process: direct heat on the food item from the quartz halogen tubes, heat reflected back from the inner surfaces of the grilling chamber and onto the food item, convection heat directed about the food item due to the grilling chamber configuration and directed heat from the slotted platen this in contact with the food item received from the halogen tubes.

First claim

What is claimed is:

1. A tabletop grill for cooking food comprising:
a grilling chamber having a highly reflective and low heat absorption inner surface for reflecting radiant energy to a food item positioned therein, the grilling chamber configured to direct emitted radiant energy in a convection manner about the food item;
at least one radiant energy generating element connected with a power circuit and emitting a substantial portion of energy in the visible light range of the electromagnetic spectrum, the radiant energy element operatively supported and positioned within the grilling chamber to direct radiant energy at the food item, the food item also receiving reflected radiant energy from the inner surface of the grilling chamber and subjected to convection heat from the emitted radiant energy;
a grill member for supporting the food item and disposed within the grilling chamber, the grill member having plural openings for radiant energy to impinge on the food item and formed of heat conducting material that conducts heat energy absorbed from the radiant energy generating element to the food item when in contact with the food item; and
a temperature controller for controlling the temperature within the grilling chamber by varying the power to the radiant energy generating element and thus the radiant energy emitted for cooking the food item while also varying the color of the visible light that is also emitted and visible through the plural openings of the grill member, the color of visible light emitted being correlated by the controller with the radiant energy emitted to provide a visible indication of temperature to a user.

2. The grill according to claim 1 wherein the radiant energy generating element comprises a quartz halogen tube lamp.

3. The grill according to claim 1 wherein a plurality of radiant energy generating elements are provided, wherein each radiant energy generating element comprises a quartz halogen tube with at least two quartz halogen tubes located in a substantial end to end configuration.

4. The grill according to claim 1 wherein the radiant energy generating assembly comprises a quartz body tungsten lamp.

5. The grill according to claim 1 wherein the inner surface of the grilling chamber comprises a low heat and light absorption and highly reflective coating.

6. The grill according to claim 1 wherein the inner surface of the grilling chamber further comprises a highly reflective member located under the radiant energy assembly.

7. The grill according to claim 6 wherein the highly reflective member is configured to capture food particles falling from the grill or slotted platen.

8. The grill according to claim 3 wherein the temperature controller controls the radiant energy assembly for controlling radiant and visible light emitted by a first quartz halogen tube and by a second quartz halogen tube by one or more of the selected operating states: independent, timed operation, temperature and visual intensity.

9. The grill according to claim 1 wherein the grilling chamber is selected from the group consisting of a two-piece mating configuration, a clamshell configuration and an enclosure with a front door configuration.

10. A grill for cooking food comprising:
a grilling chamber having a highly reflective and low heat absorption inner surface for reflecting radiant energy to a food item positioned therein, the grilling chamber configured to direct emitted radiant energy in a convection manner about the food item;
at least one radiant energy generating element connected with a power circuit and emitting a substantial portion of energy in the visible light range of the electromagnetic spectrum comprising at least two quartz halogen tubes mounted in a substantially end to end configuration, the quartz halogen tubes operatively supported and positioned within the grilling chamber to direct radiant energy at the food item, the food item also receiving reflected radiant energy from the inner surface of the grilling chamber and subjected to convection heat from the emitted radiant energy;
a grill member for supporting the food item and disposed within the grilling chamber, the grill member having plural openings for radiant energy to impinge on the food item and formed of heat conducting material that conducts heat energy absorbed from each of the quartz halogen tubes to the food item when in contact with the food item; and
a temperature controller for controlling the temperature within the grilling chamber by varying the power to the radiant energy generating element and thus the radiant energy emitted for cooking the food item while also varying the color of the visible light that is also emitted and visible through the plural openings of the grill member, the color of visible light emitted being correlated by the controller with the radiant energy emitted to provide a visible indication of temperature to a user.

11. The grill according to claim 10 wherein the temperature controller controls each quartz halogen tube so as to provide one or more of the selected operating states: independent, timed operation, temperature and visual intensity.

12. The grill according to claim 11 wherein the inner surface of the grilling chamber comprises a low heat and light absorption and highly reflective coating.

13. The grill according to claim 10 wherein the grilling chamber is selected from the group consisting of a two-piece mating configuration, a clamshell configuration and an enclosure with a front door configuration.

14. A method of cooking a food item using a tabletop grill that comprises
a grilling chamber having a highly reflective and low heat absorption inner surface for reflecting radiant energy to a food item positioned therein, at least one radiant energy generating element connected with a power circuit and emitting a substantial portion of energy in the visible light range of the electromagnetic spectrum, a grill member for supporting the food item and disposed within the grilling chamber, the grill member having plural openings for radiant energy to impinge on the food item and formed of heat conducting material that conducts heat energy absorbed from the radiant energy generating element to the food item when in contact with the food item; and a controller for controlling the temperature within the grilling, the method comprising the steps of:
supporting a food item on the grill member;
setting a power level for a level of radiant energy and a predetermined color of visible light to each be emitted from the at least one radiant energy generating element;
supplying power to the at least one radiant energy generating element with the controller and thereby generating radiant energy and cooking the food item by the radiant energy while at the same time correlating the radiant energy to the predetermined color of visible light and generating the visible light at the predetermined color that is correlated by the controller for thus providing a visual indication of temperature to a user.

15. The method of claim 14 including the step of varying the power to the radiant energy generating element by the controller and thus the radiant energy emitted for cooking the food item while also varying the color of the visible light that is also emitted and visible through the plural openings of the grill member to provide the visible indication of temperature to a user.
