There are electric water heaters on the market at present, most of which are box-type electric water heaters. It will produce scale, corrode the tank liner and electric heating tube, and affect the life of the water heater. Therefore, many water heaters are equipped with magnesium rods to prevent scale, which also increases the cost of the water heater; there is also the current box-type electric water heater. Due to the structure, only 70-85% of the heated hot water can flow out for its use, and the rest can only be stored in the water tank. It is unhygienic to reheat once

Abstract
The invention discloses a double heading safety electric water heater. The double heading safety electric water heater comprises a preheating heater body, an instant heating device, a high-power safe power source and a connecting electric wire. The preheating heater body comprises a water inlet, a cold water inlet pipe, a pressure release valve, a water inlet control valve, a water outlet, a warm water outlet pipe, a warm water switching valve, a water passing hole, a water insulation switching valve and a temperature displayer, and further comprises a warm water temperature limited switch and a cold and hot water partitioning and adjusting device which is composed of a rotary shaft, an adjusting nut, a fastening nut, a waterproof rubber gasket, a fixed water partition plate, a movable wiper plate, a spring piston, an adjusting shaft and an adjusting flower basket. The high-power safe power source is used for supplying power and is isolated from a 220V power source, so that electric shock accidents are eradicated. Meanwhile, the cold and hot water partitioning and adjusting device is arranged in the preheating heater body, 95% of heated warm water flows into the instant heating device for heating, water scale is avoided, a liner and a magnesium rod are not need, and the double heading safety electric water heater has the advantages of being capable of saving energy, safe, low in cost, large in hot water outlet amount, high in hot water outlet efficiency, facilitating part convenient and the like.
Description
technical field [0001] The invention relates to an electric water heater, in particular to a secondary heating safety electric water heater. Background technique [0002] At present, the electric water heaters on the market all use 220V grid power supply, and there are potential safety hazards, such as electric heating pipes being corroded and perforated, resulting in electric leakage accidents, and some installers have misconnected the power lines, resulting in electric water heater electric shock accidents, or improper use by users. Electric shock accidents occur, especially in the case of non-standard and unqualified household power supply lines. When using electric water heaters, once electric leakage and electric shock accidents occur, it is a shocking major accident. According to relevant information reports. In my country's electric water heater market, 54% of households have no grounding wire or unreliable grounding, or the environment is harsh (poor grounding). Th...
