The utility model is an energy-saving multi-mode variable-frequency water storage electric water heater. Due to the adoption of such a structure, when the water in the lower inner tank is heated to 75oC by the preheating heating tube, the preheating heating tube stops working. At this time, the upper inner tank The high-temperature water enters the thermostatic valve and mixes with 2-5 times the amount of cold water to form 30-35oC warm water, then re-enters the instant heating inner tank, and is reheated by the instant heating tube to reach a bathing temperature of 38-45oC. The real-time heating power of the instant heating tube is controlled by the combination of the thyristor and the temperature sensor, so that the outlet water temperature is always constant at the set temperature value, achieving a constant temperature effect.

With such a structural design, the high-temperature hot water is mixed with several times the amount of cold water through the thermostatic valve, and input into the instant hot inner tank with a volume of less than 1 liter, and heated to the bathing temperature again through the instant heating tube to improve the heating efficiency. In exchange for the heating time, the doubled amount of hot water is obtained, that is, the continuous bathing time of ordinary water heaters is more than doubled.
