Abstract: A food baking machine includes a heating device. The heating device includes a lower hot plate on a lower side of the heating device, a rotatable and vertically slidable upper hot plate on an upper side of the heating device, a rotatable connecting member for connecting the lower hot plate and the upper hot plate and a sliding member. The upper hot plate is slidably connected to the connecting member and fixes its position thereunto by the sliding member. The upper hot plate is rotatable connected with the sliding member. The upper hot plate and the lower hot plate are connected to power supply separately. The connecting member includes a first connecting segment, a second connecting segment and an axle. The second connecting segment is rotatable connected to the first connecting segment by the axle.

Abstract: A heating apparatus includes a heating element adapted to be disposed on a substrate. The heating element includes electrodes and a multi-layer conductive coating of nano-thickness disposed between the substrate and electrodes. The multi-layer conductive coating has a structure and composition which stabilize performance of the heating element at high temperatures. The multi-layer conductive coating may be produced by spray pyrolysis.

Abstract: An electrically heated towel rack including two parallel retractable arms (1,1?) and an electric heating board (2) is provided. Each of the retractable arms has a fixed portion (12) and a retractable portion (14). A connecting member (11) is disposed at one end of the fixed portion (12) for connecting the fixed portion (12) and a wall (3). The electric heating board (2) is rotatably disposed between the two retractable arms (1,1?) and supported by two support members (13), the support members (13) being respectively disposed on inner sides of the retractable portions (14) of the two retractable arms (1,1?). The electric heating board (2) can be an electric glass board. The distance between the electric heating board (2) and the wall (3) can be adjusted by pushing or pulling the retractable portions (14). Alternatively, the electric heating board (2) can be rotated to a vertical position.

Abstract: Embodiments involve 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.
