The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art in a specific case.
As shown in fig. 1, one embodiment of the present utility model discloses a hot water tank structure comprising: a first water tank 1 for storing hot water and a second water tank 2 which is located below the first water tank 1 and communicates with each other for replenishing the first water tank 1 with hot water. For example, the first tank 1 and the second tank 2 are stainless steel tanks or the like, and are not limited thereto.
The second water tank 2 is provided with a water outlet 21 and a water return port 22 for heating water through heat exchange circulation, and the water return port 22 is positioned above the water outlet 21. The second water tank 2 is also provided with a cold water inlet 23 for supplementing cold water, and the first water tank 1 is provided with a hot water outlet 11.
The hot water tank structure of this embodiment has realized hot water cold water separation, and the first water tank 1 of top is the hot water that has already been burnt, and when the people bathed out hot water, because the pressure effect, the second water tank 2 of below can be fast with the hot water that burns for first water tank 1, and first water tank 1 can export stable hot water source.
Specifically, the capacity of the first water tank 1 is larger than that of the second water tank 2, the upper first water tank 1 can provide a large amount of hot water, the lower second water tank 2 can quickly prepare hot water and continuously supply the hot water to the first water tank 1 due to small size, for example, the capacity of the first water tank 1 is 100 liters, the capacity of the second water tank 2 is 85 liters, and a small water tank of 85 liters can reach the hot water supply capacity equivalent to a large heat storage water tank of 400 liters.
