When cold water is injected into the first water tank and the second water tank through the communicated No. 4 and No. 5 water inlet valves, the No. 14 and No. 15 electric heating rods are started to heat and boil the cold water, then the No. 6 water replenishing valve is firstly communicated, and all boiled water in the first water tank is injected into the No. three warm water tank. After the boiled water is filled, the No. 4 water inlet valve is switched on, cold water is filled into a water tank, and the water tank is not heated at first. At this time, the approximate states of the three water tanks of the electric water heater are as follows: the first water tank is full of cold water, the second water tank is half of boiled water, and the third water tank is more than half of warm boiled water which is continuously cooled. When the liquid level in the second water tank drops below the intermediate liquid level L5 (the first water tank is started to heat the liquid level), the 14 electric heating rod is started to heat the first water tank to boil. When the boiled water in the second water tank is drunk, the No. 5 water inlet valve is switched on, and the cold water is not heated after being filled, and similarly, when the liquid level in the first water tank drops below the middle liquid level L2 (the heating liquid level of the second water tank is started), the No. 15 electric heating rod is started to heat and boil. The circulation is repeated, and the cold water and the hot water in the first water tank and the second water tank are alternated. No raw water is injected into the cold water in the two water tanks from boiling to drinking, and the cold water is boiled once. The working principle of the third warm water tank is simple, the third warm water tank is kept when warm water exists, boiled water in the second warm water tank is led into the third warm water tank when no warm water exists, the No. 16 electric heating rod is started to heat and preserve heat when the temperature of water in the third warm water tank is lower than 50 ℃, and the heat preservation is stopped when the temperature of water in the third warm water tank is higher than 60 ℃.
