    Abstract: Direct current power gained by photovoltaic cells can be used for heating water in a boiler. Simple installation allows use for domestic or industrial purposes, with a minimal impact to building construction. At the time of lack of sunlight intensity, water heating is provided by gas, or other heating source, or by use of a heating coil supplied by alternating current for that heating. When sunlight intensity is high, the photovoltaic cells of the present invention can be used alone. However, the source of the direct current has to be properly dimensioned in dependence on the volume of the boiler. An output 1 kWh of the source of the direct current gained by photovoltaic cells can be used to heat water of a volume of 100 L.

  • Patent number: 7994455
    Abstract: Traditional temperature-control products have the problem that the temperature of the working surface reaches the setting temperature too slowly when heating up or recovering from a temperature drop. A traditional temperature control circuit and temperature-settings selector components are modified to solve this problem. When heating begins, the modified circuit increases the initial setting temperature to be above the target setting temperature. The modified circuit then adjusts the setting temperature by measuring the heating power consumption. Once the working surface of the temperature control product reaches the initial setting temperature, the heating power consumption drops and the modified circuit reduces the temperature setting to the target setting temperature. The temperature control product can rapidly achieve the target temperature. A positive-temperature-coefficient heating component is used in the temperature control product.

    Abstract: A system and method for providing multiple cooking modes and an ability to automatically heat cooking vessels and other objects using RFID technology, and an ability to read and write heating instructions and to interactively assist in their execution. An induction heating range is provided with two antennas per hob, and includes a user interface display and input mechanism. The vessel includes an RFID tag and a temperature sensor. In a first cooking mode, a recipe is read by the range and the range assists a user in executing the recipe by automatically heating the vessel to specified temperatures and by prompting the user to add ingredients. The recipe is written to the RFID tag so that if the vessel is moved to another hob, into which the recipe has not been read, the new hob can read the recipe from the RFID tag and continue in its execution.
