Abstract
The utility model discloses an induction heating water heater, comprising an AC frequency conversion power supply, an induction heating pipe, a water storage tank, an uptake pipe, and a downtake pipe. The induction heating pipe comprises an induction coil and a water conduit made of non-magnetic material and a heating steel pipe positioned in the water conduit. The induction heating pipe is arranged blow the water storage tank, whose outlets at both ends are respectively communicated with one uptake pipe and the downtake pipe. The water storage tank is also communicated with the uptake pipe and the downtake pipe. When the water storage tank is full of water, the induction heating pipe emits heat under the AC frequency conversion power supply. As there is density difference in water temperature between uptake and downtake pipes in the water storage tank, hot water runs from one end of the induction heating pipe, through the uptake pipe and into the water storage tank. Meanwhile, cooling water in the water storage tank runs from the other end of the downtake pipe and into the induction heating pipe. With natural circulation of water, cooling water in the water storage tank is heated up.
