Because the structure of double inner containers is adopted, the double-inner-container water tank is ensured to have good heat storage and heat preservation performance. When hot water is needed, the hot water in the inner liner flows out through the water outlet valve for people to use. Because the double-liner pressure-bearing structure is adopted, hot water between the outer liner and the inner liner has a pressure-bearing effect, the double-liner pressure-bearing structure greatly increases the water yield, and ensures the water outlet stability. With the continuous use of hot water, the hot water between the outer liner and the inner liner can continuously heat new cold water entering the inner liner, and the continuity of the hot water is ensured. The water inlet valve and the water outlet valve are both threaded interface water valves, so that the quick connection can be realized, the good sealing performance is ensured, the water seepage is avoided, and the working stability of the water heater is ensured. The arrangement of the circular reinforcing ribs greatly reduces the stress at the welding positions of the water inlet valve, the water outlet valve and the outer liner end cover, and avoids the fracture of the welding positions of the water inlet valve, the water outlet valve and the outer liner end cover, so that the sealing performance of the outer liner is ensured, the number of the linear reinforcing ribs on the outer liner end cover is four, the uniform arrangement of the linear reinforcing ribs is favorable for outward dispersion of the stress, and the service life of the outer liner is greatly prolonged. The utility model discloses not only the heat-retaining ability is good, and hot water homogeneity is good, and the water yield is big moreover.
