Abstract
The invention publishes an induction heating type electric boiler, which includes the exchange frequency conversion power source, the induction heating pipe, the water can, the ascending pipe, the down pipe. The induction heating pipe includes: the induction coil, the water pipeline which is made of non-magnetism material as well as the heat steel pipe which installs in the side of the water pipeline. The induction heating pipe places under the watering can, the water gaps in the two end of the induction heating pipe separately connect an ascending pipe and a down pipe. The watering can also connects with the ascending pipe and the down pipe. After the watering can water-filled, the induction heating pipe heat under the frequency conversion power source function. Because there is a water temperature density contrast between the ascending pipe and the down pipe in the watering can, the hot water flow out into the watering can from the one end of the induction heating pipe after the ascending pipe. At the same time, the cold water in watering can flow into the induction heating pipe after the down pipeline from another end. Under the water natural circulation, the cold water watering can heat up.

Description of drawings
Fig. 1 is the main pseudosection of inductive heating type electric water heater embodiment of the present invention;
Among the figure: 1, shell body 2, heat-insulation layer 3, safety valve 4, check-valves 5, blowoff valve 6, AC power 7, panel type electric controller 8, induction heating pipe 9, tedge 10, down-comer 11, water tank 12, cold water inlet 13, hot water fairlead 14, hot water outlet 15, temperature sensor 16, stube cable
The specific embodiment
Below in conjunction with drawings and embodiments the present invention is described in further detail.
Shown in Figure 1 is inductive heating type electric water heater.Described induction heating pipe 8 comprises: in the inside of induction coil, there are two ends of making to have the ventilating water pipe of flange with fiberglass, the inside at described ventilating water pipe, heating pipe that useful permeability magnetic material is made or heating round steel, the gap of circulation water is arranged between the external diameter of the internal diameter of described ventilating water pipe and described heating pipe or heating round steel, be bolted with the reducing concentric reducer at the two ends of described ventilating water pipe.Described induction heating pipe 8 levels be installed in water tank 11 below.Weld or be screwed onto with tedge 9 at one end outlet pass place of induction heating pipe 8, and weld or is screwed onto with down-comer 10 at the other end outlet pass place of induction heating pipe 8.Tedge 9 penetrates into the inside of water tank from the bottom of water tank 11, and in its interface seal welding.Tedge 9 is in the vertical height of the water tank 11 inside inside clear height less than water tank 11, and tedge 9 should satisfy the needs of the flow of hot water output in the tedge 9 in the difference of the height of water tank 11 inside and water tank 11 internal height.Down-comer 10 seal weldings are in water tank 11 bottoms, and down-comer 10 is communicated with the water route of water tank 11.Hot water fairlead 13 can be with reference to the height of tedge 9 at the height of water tank 11 inside.Cold water inlet 12 places are bolted with safety valve 3 and can be communicated with outside tap water pipe line.Hot water outlet 14 can be communicated with outside heat supply water lines.Heat-insulation layer 2 reaches exposed tedge 9 outside with water tank 11, down-comer 10 and seals insulation.Check-valves 4 is to make water tank 11 maintain water state.Blowoff valve 5 can be removed the dirt in water tank 11 and the pipeline.Panel type electric controller 7 is installed on the outer surface of shell body 1.Temperature sensor 15 is placed in the outer surface of water tank 11.Stube cable 16 is electrically connected described induction coil in the induction heating pipe 8 and AC power 6.AC power 6 is variable-frequency power sources, and it is transformed into intermediate frequency or superaudio power supply with power frequency supply.
The course of work of inductive heating type electric water heater of the present invention is: after water tank 11 was full of water, panel type electric controller 7 imposed on the voltage of AC power 6 on the described induction coil in the induction heating pipe 8.At this moment, described heating pipe in the induction heating pipe 8 or heating round steel begin heating.Owing in water receiver 11, between tedge 9 and the down-comer 10 a water temperature density contrast is arranged, makes ventilating water pipe one end of hot water from induction heating pipe 8 flow out to water tank 11 the insides through tedge 9.Simultaneously, the cold water of 11 li of water tanks flow into the described ventilating water pipe from the other end of induction heating pipe 8 through down-comer 10 and goes.Under the Natural Circulation of water, the cold water of water tank 11 is heated.
