In U.S. 20100012643, Hong Kong Applied Science and Technology Research Institute Co., Ltd. (Shatin, CN) discloses a food warmer that uses a nano thickness heating material as the heating element. The heating element has a fast response and is energy efficient. The temperature of the food warmer can be precisely controlled. The food warmer may be used to heat cold food to a desired temperature, maintain a temperature of already heated food, and/or cook uncooked food say inventors Geng Li, Joey C Y Chow, Chih Lin I and Edward S. Yang.
The nano heating element is energy efficient and quick to heat to the desired temperature. The food warmer uses a temperature control system with rapid and accurate response to maintain the food at a desired temperature and/or heat the food to a desired temperature. The food warmer uses a rechargeable power supply, e.g. a battery to provide power for the heating element. The food warmer may include insulation to retain the heat provided by the heating element. The insulation may be located on the bottom and/or sides. If the food warmer is box shaped, then the insulation may be located on the top as well.
One or more layers of a conformal nano thickness heating material that is coated onto a glass surface as the heating element for the food warmer.
