The second water inlet pipeline 6 is connected to the inlet end of the domestic water pipeline 49. The domestic hot water pipeline 7 is connected to the outlet end of the domestic water pipeline 49. The water in the second water inlet pipeline 6 is the normal temperature domestic water that has not been heated by the heat exchanger 4. The water in the domestic hot water pipeline 7 is the domestic hot water heated by the heat exchanger 4.

[0032] Furthermore, the heat exchanger 4 includes a housing. An accommodation cavity 41 is provided inside the housing. The housing is provided with a first water inlet 42, a second water inlet 43, a first water outlet 44, a second water outlet 45, a first gas inlet 46, and a first exhaust port 47 for exhausting gas. The drinking water pipeline 48 and the domestic water pipeline 49 are arranged inside the accommodation cavity 41. The two ends of the drinking water pipeline 48 are respectively connected to the first water inlet 42 and the first water outlet 44. The two ends of the domestic water pipeline 49 are respectively connected to the second water inlet 43 and the second water outlet 45. The other end of the pure water pipeline 3 is communicated with the first water inlet 42. The hot drinking water pipeline 10 is communicated with the first water outlet 44.

[0033] Specifically, the integrated heating water purifier further includes an exhaust gas pipeline 56, and the exhaust gas pipeline 56 is communicated with the first exhaust port 47.

[0034] Specifically, the drinking water pipeline 48 and the domestic water pipeline 49 are two completely independent pipelines. The two ends of the drinking water pipeline 48 are respectively and hermetically connected to the first water inlet 42 and the first water outlet 44, and the two ends of the domestic water pipeline 49 are respectively and hermetically connected to the second water inlet 43 and the second water outlet 45.

[0035] Further, the gas transmission pipeline 5 includes a burner 51, a gas inlet pipeline, a gas outlet pipeline 52 and an air inlet pipeline. The gas inlet pipeline and the air inlet pipeline are both communicated with the intake end of the burner 51. One end of the gas outlet pipeline 52 is connected to the outlet end of the burner 51, and the other end is connected to the first air inlet 46. The gas inlet pipeline supplies gas to the burner 51, and the air inlet pipeline supplies oxygen to the burner 51. The gas and oxygen are mixed and burned in the burner 51 to form high-temperature flue gas, and then the high-temperature flue gas is transported to the accommodating cavity 41 of the heat exchanger 4 through the gas outlet pipeline 52 for heat transfer with the drinking water in the drinking water pipeline 48 and / or the domestic water in the domestic water pipeline 49 to achieve the heating effect. It should be noted that this heating process is indirect heat transfer, and the drinking water and domestic water do not directly contact the high-temperature flue gas.

[0036] Further, the gas inlet pipeline includes a gas inlet pipeline 53, a gas valve 54 and a regulating valve 55. The gas inlet pipeline 53 is connected to the intake end of the burner 51, and both the gas valve 54 and the regulating valve 55 are arranged on the gas inlet pipeline 53. The gas valve 54 is used to conduct or close the gas inlet pipeline 53. When the water purifier needs to heat water, the gas valve 54 is opened, and the gas inlet pipeline 53 supplies gas to the burner 51 to provide high-temperature flue gas for the heat exchanger 4. The high-temperature flue gas conducts heat transfer with the water in the drinking water pipeline 48 and the domestic water pipeline 49 to heat the drinking water and domestic water. When the water purifier does not need to heat water, the gas valve 54 is closed to close the gas inlet pipeline 53. By adjusting the opening degree of the regulating valve 55, the gas flow can be adjusted, thereby realizing the adjustment of the heating power of the burner 51.

[0037] Further, the air inlet pipeline includes an air inlet pipeline 57 and a blower 58. A second branch port 59 is provided on the gas inlet pipeline 53. The air inlet pipeline 57 is connected to the second branch port 59, and the blower 58 is arranged on the air inlet pipeline 57. The air inlet pipeline 57 is used to supply oxygen to the burner 51, and the blower 58 is used to assist the air inlet pipeline 57 to supply oxygen to the burner 51 so that the gas in the burner 51 can burn and heat.

[0038] Further, a first NTC temperature sensor is provided on the first pipeline 31, and a second NTC temperature sensor is provided on the drinking hot water pipeline 10, which can monitor the drinking water before and after heating, facilitating the adjustment of the heating power of the heat exchanger 4 and the control of the outlet water temperature of the water purifier.

[0039] Further, the first water inlet pipeline 1 includes a first water inlet pipe 11, a booster pump 12, and a second solenoid valve 13. The second solenoid valve 13 and the booster pump 12 are sequentially arranged on the first water inlet pipe 11, and the first water inlet pipe 11 is connected to the raw water inlet 21.

[0040] Further, the second water inlet pipeline 6 includes a second water inlet pipe and a water-gas linkage valve. The water-gas linkage valve is arranged on the second water inlet pipe, and the second water inlet pipe is connected to the second water inlet 43. The function of the water-gas linkage device is to ensure that the gas valve 54 can be opened only when the water pressure is sufficient and the water flows into the heat exchanger 4; when the water flow stops or the pressure is insufficient, the gas inlet pipeline 53 is automatically cut off to prevent the equipment from being burned out due to water shortage.

[0041] Further, the regulating pipeline includes a first pipeline 31 and a first reversing valve 33. The first reversing valve 33 is arranged on the first pipeline 31. The first reversing valve 33 has two water outlet ports, one of which is communicated with the normal temperature water pipeline 9, and the other water outlet port is communicated with the hot drinking water pipeline.

The normal temperature water pipeline 9 is communicated with the water outlet end of the first solenoid valve 92. The hot drinking water pipeline is communicated with the water outlet end of the water pump 36. When the water pump 36 starts to generate zero pressure, the zero-pressure valve 35 closes, and the water pressure behind the zero-pressure valve 35 is zero. When the negative pressure generated after the water pump 36 starts, the zero-pressure valve 35 is opened, and the pressurized water in the first pipeline 31 flows out in a non-pressurized state. The water outlet flow rate of the water pump 36 is not affected by the change of the water pressure in the first pipeline 31, and the water outlet flow rate can be accurately controlled.

[0046] Furthermore, the integrated heating water purifier further includes a return pipeline 103. A second reversing valve 102 is provided on the hot drinking water pipeline.

The second reversing valve 102 is a three-way reversing valve with one inlet and two outlets. The two outlets are respectively connected to the main pipeline of the drinking hot water pipeline 101 and the return pipeline 103.

[0048] When the water temperature in the drinking hot water pipeline 10 is not enough, the low-temperature hot water in the drinking hot water pipeline 10 is led back to the front of the water pump 36 through the return pipeline 103, and then reheated through the heat exchanger 4 to reach the required water temperature.

[0049] Example 4:
