Abstract
The utility model provides a double-tube two-gear instant heating type electric water heater, which comprises a water inlet pipe 1, a water outlet pipe 5, and two water tanks 2 and 4. The two water tanks 2 and 4 are connected by a water connecting pipe 3 to be in a U shape. All the pipes of the electric water heater are temperature-resistant and insulated PPR pipes and the sizes of the PPR pipes are 15-60 cm. Electric heaters 18 and 17, free of any insulating layer, are arranged in the two water tanks 2 and 4. The live wire terminals 15 and 12 of the electric heaters 18 and 17 are arranged along the water inlet direction. Under the control of branch power switches 9 and 8, an indicating lamp 10 is respectively connected in parallel with the electric heaters 18 and 17, wherein the electric heaters 18 and 17 are respectively controlled by temperature controllers 14 and 11. According to the technical scheme of the utility model, the double-tube two-gear instant heating type electric water heater has the advantages of low cost and convenient installation. The electric heaters 18 and 17 do work in the water at a low temperature, thus being hard to burn out. The current values at the water inlet and the water outlet of the electric water heater are smaller than 0.3 mA, so that the electric water heater is very safe to use. Meanwhile, since the electric heaters 18 and 17 directly do work on the water, the electric heating conversion rate of the electric water heater is maximum. Moreover, based on the combined application of the indicating lamp 10 and the temperature controllers 14 and 11, the electric heaters 18 and 17 are ensured to do work at a low temperature. The double-tube two-gear instant heating type electric water heater is resistant to over-temperature, over-voltage and dry burning, and the service life of the electric water heater is therefore prolonged.
