[0015] The following further describes the detailed embodiments of the present utility model with reference to the drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] As Figure 1 shown, it is a water circuit structure with dual-pump water output, including:

[0017] A cold water tank 3, a make-up water solenoid valve 4 and a hot water tank 5; one water inlet and two water outlets are provided on the cold water tank 3, two water inlets and one water outlet are provided on the hot water tank 5, one water inlet of the cold water tank 3 is communicated with an external water source, and one water outlet of the cold water tank 3 is communicated with one water inlet of the hot water tank 5 through the make-up water solenoid valve 4;

[0018] The first reversing valve 8, the second reversing valve 13 and the water outlet end 14; the first reversing valve 8 has two inlets and one outlet. One inlet of the first reversing valve 8 is communicated with the other water outlet of the cold water tank 3, and the other inlet of the first reversing valve 8 is communicated with the water outlet of the hot water tank 5. The second reversing valve 13 has one inlet and two outlets. One outlet of the second reversing valve 13 is communicated with the other water inlet of the hot water tank 5, and the other water outlet of the second reversing valve 13 is communicated with the water outlet end 14;

[0019] The heating element 11, the first water pump 9 and the second water pump 10; the water inlet of the first water pump 9 is communicated with the water outlet of the first reversing valve 8, the water inlet of the second water pump 10 is communicated with the water outlet of the hot water tank 5, the water inlets of the heating element 11 are respectively communicated with the water outlets of the first water pump 9 and the second water pump 10, and the water outlet of the heating element 11 is communicated with the inlet of the second reversing valve 13; and

[0021] When in use, in the standby state, first, the second reversing valve 13 is used to switch to supplement hot water to the hot water tank 5. When 45-degree and 60-degree water is needed, for 45-degree and 60-degree water outlet, the first water pump 9 is used to draw cold water from the cold water tank 3, and the second water pump 10 is used to draw hot water from the hot water tank 5.
