After the hot water is used, the water mixing valve is closed, the heat exchanger 1 continues to work at the moment, heat generated by the heat exchanger 1 is absorbed by water in the water tank 1, so that the temperature of the water in the water tank 1 is raised, when the temperature sensor monitors that the water temperature in the water tank 1 reaches the set temperature, the heat exchanger 1 is controlled to stop working, and at the moment, the water in the water tank 2 plays a role in heat accumulation.
3. The cold water in the second heat exchange tube 4 is heated by the water heat of the water tank 2, so that the second heat exchange effect in the bathing process is achieved, and longer bathing time is ensured.
4. When the water in the water tank 1 for heat storage is insufficient, an appropriate amount of water can be added to the water tank 2 through the water replenishment pipe 10.
The foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited to the above-mentioned embodiment, but is not limited to the above-mentioned embodiment, and any simple modification, equivalent change and modification made by the technical matter of the present utility model can be further combined or replaced by equivalent embodiments within the scope of the technical proposal of the present utility model without departing from the scope of the technical proposal of the present utility model.
