In summary, the embodiment of the invention provides a multipurpose water heating device, a multifunctional bathroom system and a control method for heating water, wherein a domestic hot water waterway is formed by a first pipeline 1, a second pipeline 2, a first heat exchanger 17 and a third pipeline 3, when a water consumption point communicated with a first water outlet 31 is opened, water flowing in from a first water inlet 30 flows through the first pipeline 1 and the second pipeline 2, so that a first flow sensor 21 detects that the second pipeline 2 has a water flow signal, a first burner 34 starts to work, water flowing through the first heat exchanger 17 is heated, and the heated water flows into the water consumption point after flowing through the third pipeline 3, so that the domestic hot water function is realized; the water outlet instant heating circulation waterway is formed by the first pipeline 1, the fourth pipeline 4, the first pipeline 5 of the second heat exchanger 18, when the first flow sensor 21 detects that the second pipeline 2 has no water flow signal, and when the water temperature of the pipeline connected between the first water outlet 31 and the water consumption point is lower than the preset temperature, the first electromagnetic valve 20 is started, the circulation pump 19 is started and the second burner 35 works, so that the water of the pipeline connected between the first water outlet 31 and the water consumption point flows into the second heat exchanger 18 through the first water inlet 30 for circulation heating, thereby ensuring that the hot water can flow out immediately when the water consumption point is opened, and further realizing the water outlet instant heating function; the first pipeline 1, the second pipeline 2, the first heat exchanger 17, the third pipeline 3 and the sixth pipeline 6 form a hot water injection waterway of the bath container 25, when the hot water injection function of the bath container 25 is started, the second electromagnetic valve 24 is started, the first burner 34 starts to work, water flowing in from the first water inlet 30 flows through the first pipeline 1 and the second pipeline 2 in sequence, then enters the first heat exchanger 17 to be heated, and the water heated by the first heat exchanger 17 flows to the bath container 25 communicated with the circulating water inlet 32 through the circulating water inlet 32 after flowing through the third pipeline 3 and the sixth pipeline 6, so that the hot water injection function of the bath container 25 is realized; the seventh pipeline 7, the second pipeline of the second heat exchanger 18 and the eighth pipeline 8 form a circulating heat-preserving waterway of the bath container 25, when the heat-preserving function of the bath container 25 is started, the water suction pump 27 is started, so that water in the bath container 25 can flow through the seventh pipeline 7 through the circulating water inlet 32 and then flow into the second pipeline of the second heat exchanger 18 for heating, and the heated water in the second pipeline of the second heat exchanger 18 flows through the eighth pipeline 8 and then flows into the bath container 25 again through the circulating water outlet 33, thereby realizing the heat-preserving function of the bath container 25.

In addition, as the existing water heater utilizes the original domestic hot water heating system to realize the water outlet instant heating function, the design of the water outlet instant heating function is limited by the structure of the domestic hot water heating system, so that the performance optimization and upgrading of the water outlet instant heating function are greatly limited, the domestic water in the first heat exchanger 17 is heated by the first burner 34 to realize the domestic hot water function, and the second heat exchanger 18 is heated by the second burner 35 to realize the circulating heating of the water in the water pipe, so that the water outlet instant heating function is realized, the constraint of the structure of the original domestic hot water heating system on the water outlet instant heating function is avoided, and meanwhile, the influence of the water outlet instant heating function on the original domestic hot water heating system is reduced.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
