Abstract

A domestic appliance for cooling and heating food items and/or beverage items may include a shell, a door, a cooling compartment defined at least in part by the shell and the door, the compartment being configured store the food items and/or the beverage items in a cooled environment and at least one solid state heating element inside of the cooling compartment, the at least one solid state heating element configured to emit infrared radiation to heat at least one of the food items and/or the beverage items without heating the surroundings or other contents of the cooling compartment.

First claim

The invention claimed is:

1. A domestic appliance for cooling and heating food items and/or beverage items, the domestic appliance comprising:
a shell;
a door;
a cooling compartment defined at least in part by the shell and the door, the cooling compartment being configured to store the food items and/or the beverage items in a cooled environment; and
at least one solid state heating element comprising at least one of a diode or a semiconductor diode configured to apply a digital heat injection (DHI) which comprises a high intensity, narrow band, solid state infrared radiation (IR), the at least one solid state heating element being disposed inside of the cooling compartment and exposed to the cooled environment of the cooling compartment, the at least one solid state heating element configured to emit the solid state infrared radiation such that the DHI applies direct thermal transfer of energy via targeted light transfer for direct penetration into at least one of the food items and/or the beverage items to heat the at least one of the food items and/or the beverage items without heating ambient surroundings within the cooling compartment or other contents of the cooling compartment.

2. The domestic appliance of claim 1 , further comprising a heating compartment defined inside of the cooling compartment for heating at least one of the food items and/or the beverage items,
wherein the at least one solid state heating element is positioned inside of the heating compartment to heat at least one of the food items and/or the beverage items.

3. The domestic appliance of claim 2 , wherein the heating compartment is a drawer.

4. The domestic appliance of claim 2 , wherein at least one interior surface of the heating compartment includes a retroreflective material to reflect the solid state infrared radiation to at least one of the food items and/or the beverage items.

5. The domestic appliance of claim 4 , wherein the retroreflective material comprises cube corner retroreflectors.

6. The domestic appliance of claim 1 , further comprising a shelf inside of the cooling compartment,
wherein the at least one solid state heating element is positioned to emit the solid state infrared radiation to heat at least one of the food items and/or the beverage items located on the shelf.

7. The domestic appliance of claim 6 , wherein a surface of the shelf and/or at least one interior surface of the cooling compartment includes a retroreflective material to reflect the solid state infrared radiation to at least one of the food items and/or the beverage items.

8. The domestic appliance of claim 7 , wherein the retroreflective material comprises cube corner retroreflectors.

9. The domestic appliance of claim 1 , wherein at least one interior surface of the cooling compartment includes a retroreflective material to reflect the solid state infrared radiation to at least one of the food items and/or the beverage items.

10. The domestic appliance of claim 9 , wherein the retroreflective material comprises cube corner retroreflectors.

11. The domestic appliance of claim 1 , further comprising a controller configured to control the cooling compartment and the at least one solid state heating element.

12. The domestic appliance of claim 11 , further comprising an item identification module configured to detect identification information of at least one of the food items and/or the beverage items and the item identification module configured to communicate the identification information to the controller.

13. The domestic appliance of claim 12 , wherein the controller is configured to activate the at least one solid state heating element based on the identification information.

14. The domestic appliance of claim 12 , wherein the item identification module is a universal product code (UPC) scanner and the identification information comprises a UPC label on at least one of the food items and/or the beverage items to identify at least one of the food items and/or the beverage items.

15. The domestic appliance of claim 12 , further comprising a network communication module configured to communicate with an external data storage system via Internet.

16. The domestic appliance of claim 15 , wherein the network communication module is a Wi-Fi module.

17. The domestic appliance of claim 11 , further comprising a user interface configured to exchange information between a user and the controller.

18. The domestic appliance of claim 17 , wherein the user interface comprises a display screen and at least one user input device.

19. The domestic appliance of claim 18 , wherein the at least one user input device comprises at least one of a touch-sensitive input device that is substantially coextensive with the display screen and a microphone.

20. The domestic appliance of claim 11 , wherein the at least one solid state heating element comprises a plurality of solid state heating elements configured to be activated individually by the controller.

21. The domestic appliance of claim 20 , wherein at least two of the plurality of solid state heating elements are configured to emit the solid state infrared radiation at different bandwidths.
