The first water passing path 25 is in parallel with the first heating structure, and the first valve body 26 is connected with the first water passing path 25, the first heating water path 2 upstream of the first heating structure, and the water inlet 21. The second water passing path 43 is in parallel with the second heating structure, and the second valve body 44 is connected with the second water passing path 43, the first heating water path 2 downstream of the first heating structure, and the second heating water path 4 upstream of the second heating structure.

[0033] In the structure provided in the specific embodiment, by utilizing the parallel connection of the first water passing path 25 and the first heating structure, and the parallel connection of the second water passing path 43 and the second heating structure, four kinds of water bodies flowing through the first heating structure without flowing through the second heating structure, not flowing through the first heating structure and the second heating structure, flowing through the second heating structure without flowing through the first heating structure, and flowing through the first heating structure and the second heating structure can be obtained by controlling the first valve body 26 and the second valve body 44. The four kinds of water bodies have different temperatures respectively, which can further meet more diversified water demand, thereby greatly improving the usability of the water supply system 1.

[0034] In a specific embodiment of the present application, referring to Figure 2 , the water supply system 1 further comprises a heat storage structure 3. One of the first heating structure and the second heating structure is a heat exchange member 23, the heat exchange member 23 is provided with a water body heat exchange channel 231 and a heat conduction structure. The water body heat exchange channel 231 is connected to the first heating water path 2, and the heat conduction structure is in heat conduction connection with the heat storage structure 3 and the water body heat exchange channel 231.

[0035] Due to the relative independent relationship of the first heating structure and the second heating structure, the setting of two heating components generally has a high cost. In the structure provided in the embodiment, the heat storage structure 3 is used to cooperate with the heat exchange component 23 as one of the first heating structure and the second heating structure, the heat storage structure 3 can use the heat stored in the heat storage structure 3 to heat the water flowing through the water body heat exchange channel 231, the heat storage structure 3 stores heat or recovers heat in a low water demand period, and releases the stored heat in a water body heat exchange channel 231 peak period, which can reduce the energy consumption of direct heating, store heat in a low valley electricity price period, release heat in a peak period, reduce operation cost, and improve energy saving effect. The heat storage structure 3 can provide a stable heat source for the heat exchange component 23, and can also avoid the water temperature fluctuation caused by insufficient instantaneous heating power of the common heating component, can support the heating demand of large flow water body, and effectively improves the reliability of the water supply system 1.

[0037] In the structure provided in the embodiment, on the basis of the first heating structure being the heat exchange component 23, the second heating structure is set as the heater 42, the water flowing through the first heating structure is preheated by the heat exchange component 23 to form warm water, and then heated by the second heating structure to obtain hot water with a higher temperature. Through the preheating effect of the heat exchange component 23, the demand for power and heating time of the heater 42 for outputting hot water can be reduced, the comprehensive energy consumption is greatly reduced, and it is beneficial to realize instant output of large flow hot water, and the availability of the water supply system 1 is effectively improved.

[0038] Further, the waterway system can further include a heat conduction channel, the heat conduction channel is thermally connected with the second heating structure and the heat storage structure 3, and when the second heating structure is heating, the heat storage structure 3 can store heat through the heat conduction channel, further improving the energy utilization rate of the water supply system 1.

[0039] In an embodiment of the present application, referring to Figure 1 , the water supply system 1 can further include a first temperature sensor 24 and a controller, the first temperature sensor 24 is arranged in the first heating waterway 2 downstream of the first heating structure and upstream of the second valve body 44, and the controller is signal connected with the first temperature sensor 24, the second valve body 44, and the heater 42.

[0040] In the structure provided in the specific embodiment, by arranging the first temperature sensor 24 downstream of the first heating structure and upstream of the second valve body 44, the first temperature sensor 24 can be used to monitor the temperature of the water body output from the first heating structure, so that the controller can determine whether the water output from the first heating structure needs to be heated again according to the water temperature obtained by the first temperature sensor 24. When the determination result is that the water needs to be heated again, the controller can control the second valve body 44 to open the second heating water path 4, so that the heater 42 can be used to heat the water again to meet the temperature requirement of the water.

[0041] Further, if it is determined that the water needs to be heated, the controller can also determine the parameters of the heater 42 for heating the water, such as heating power, heating time, etc., according to the water temperature obtained by the first temperature sensor 24, so that the unnecessary energy consumption of the heater 42 can be reduced, the energy waste can be reduced, and the energy utilization rate of the water supply system 1 can be improved while meeting the temperature requirement of the water.

[0042] In a specific embodiment of the present application, the water body is heated by participating in Figure 2 、 Figure 3 the heat storage structure 3 can include a heat storage water tank 31, a heat exchange inlet water path 32, and a heat exchange outlet water path 33, and the heat conduction structure includes a heat exchange medium passage 232 which is in heat conduction connection with the water body heat exchange passage 231. The heat storage water tank 31 has a medium outlet 312 and a medium inlet 311, the heat exchange inlet water path 32 is connected with the medium outlet 312 and the heat exchange medium passage 232, and the heat exchange outlet water path 33 is connected with the medium inlet 311 and the heat exchange medium passage 232.

[0043] In the structure provided in the specific embodiment, specifically, the heat storage structure 3 uses a flowable heat exchange medium to realize heat storage and heat exchange, which can improve the heat transfer efficiency while keeping the water temperature of the water body heat exchange passage 231 stable, and the heat exchange medium is isolated from the water body for heat exchange, which can ensure long-term and stable operation of the first heat exchange structure and solve the problems of large heat loss and slow response of the traditional heat storage system.

[0044] Optionally, a circulating pump 37 can also be arranged in the heat exchange inlet water path 32 and / or the heat exchange outlet water path 33. The high-temperature heat exchange medium can flow from the heat storage water tank 31 into the heat exchange inlet water path 32 under the pumping of the circulating pump 37, and then flow into the heat exchange medium passage 232 for heat exchange. The low-temperature heat exchange medium can also flow from the heat exchange medium passage 232 into the heat exchange outlet water path 33 under the pumping of the circulating pump 37, and then flow back into the heat storage structure 3 through the medium inlet 311 for heat storage.

[0045] In a specific embodiment of the present application, the water body is heated by participating in Figure 1The water supply system 1 further comprises a second temperature sensor 34 connected to the heat exchange water inlet channel 32 and / or the heat exchange water outlet channel 33 and a controller connected to the second temperature sensor 34, the first valve 26 and the second valve 44.

[0046] In the structure provided in the specific embodiment, the second temperature sensor 34 is used to detect the temperature of the heat exchange medium flowing into the heat exchange medium channel 232 and / or flowing out of the heat exchange channel, the controller can obtain the heat exchange condition of the heat exchange medium through the second temperature sensor 34, and further predict whether the water body heat exchange in the heat exchange element 23 is sufficient according to the temperature of the heat exchange medium obtained by the second temperature sensor 34, so that the second valve 44 can be adjusted in time when it is predicted that the water body heat exchange is insufficient, so as to use the heater 42 to heat the water body again, thereby meeting the temperature requirement of the outlet water.

[0047] In the specific embodiment of the present application, referring to Figure 1 The water supply system 1 further comprises a water supplement channel 35, a pressure relief channel 36, a one-way pressure relief valve 361 and a water supplement valve 351, one end of the water supplement channel 35 is connected to a water source and the other end is connected to the heat storage water tank 31, one end of the pressure relief channel 36 is connected to the top of the heat storage water tank 31 and the other end is connected to a waste outlet, the one-way pressure relief valve 361 is connected to the pressure relief channel 36, and the water supplement valve 351 is connected to the water supplement channel 35.

[0048] When the temperature of the heat exchange medium in the heat storage water tank 31 is too high, the heat exchange medium may change phase, resulting in high-temperature steam in the heat storage water tank 31, which may cause the heat storage water tank 31 to be subjected to excessive pressure, and the material of the heat storage water tank 31 may be damaged under the action of the pressure, which may cause a series of safety problems such as explosion, water leakage and short circuit, and the overheating of the heat storage water tank 31 may also affect the structural strength and service life of the material of the heat storage water tank 31, which is not conducive to the stable operation of the water supply system 1.

[0049] In the structure provided in the specific embodiment, the pressure relief channel 36 and the one-way pressure relief valve 361 can be used to discharge the high-temperature heat exchange medium or high-temperature steam in the heat storage water tank 31 when the temperature of the heat storage water tank 31 is too high and the pressure is too large, thereby achieving the effect of pressure relief. The water supplement channel 35 and the water supplement valve 351 can be used to supplement the heat exchange medium in the heat storage water tank 31 from the water source, and after the high-temperature heat exchange medium or steam in the heat storage water tank 31 is discharged, the heat exchange medium with a lower temperature is supplemented, which can replace the discharged high-temperature heat exchange medium to be heated again, thereby maintaining the total amount of the heat exchange medium contained in the heat storage water tank 31 while maintaining the safety and stability of the water supply system 1 by using the pressure relief method, thereby reducing the negative impact of pressure relief on the heat storage performance of the heat storage water tank 31.

[0050] In the detailed description of the present application, refer to Figure 1 The water supply system 1 can further include a third temperature sensor 51 and a pre-water path 5, one end of the pre-water path 5 being connected to the water source and the other end being connected to the water inlet 21, and the third temperature sensor 51 being connected to the pre-water path 5.

[0051] In the structure provided in the present embodiment, by arranging the third temperature sensor 51 in the pre-water path 5, the temperature of the water about to be input into the first heating water path 2 can be monitored, and the water flow can be selected based on the water inlet temperature in combination with the water temperature demand, for example, when the water inlet temperature is relatively high, the second heating structure can directly heat the water to the required temperature without preheating through the first heating structure, at this time, the first valve body 26 can be controlled to make the water not flow through the first heating structure, thereby saving the energy stored in the first heating structure, and the temperature of the water outlet of the water supply system 1 can meet the water demand. For another example, when the water inlet temperature is relatively low, even if the water demand temperature is not high, the first valve body 26 and the second valve body 44 can be controlled to make the water be heated twice by the first heating structure and the second heating structure, thereby making the water outlet temperature meet the water demand, effectively improving the flexibility of the water supply system 1.

[0052] As shown in Figure 1 The pre-water path 5 can specifically be connected with a water inlet pump 52, a water quality detection member 53, a pre-filter element 54, a reverse osmosis filter element 55, a post-filter element 56, and a water inlet valve 57. The pre-filter element 54, the water inlet valve 57, the water inlet pump 52, the reverse osmosis filter element 55, and the post-filter element 56 are sequentially connected, and the pre-filter element 54 can preliminarily filter out larger impurities in the water, thereby reducing the risk of clogging or damage of the water inlet valve 57, the water inlet pump 52, and other subsequent water path elements.

[0053] Refer to Figure 1 and Figure 3 The water supply system 1 can further include a backflow water path 58, a waste water path 7, a backflow valve 581 connected in the backflow water path 58, and a waste water valve 71 connected in the waste water path 7. The water quality detection member 53 is arranged downstream of the pre-filter element 54, the reverse osmosis filter element 55, and the post-filter element 56, the backflow water path 58 connects the pre-water path 5 downstream of the water quality detection member 53 and the pre-water path 5 upstream of the pre-filter element 54, and the waste water path 7 is connected to a waste water outlet of the reverse osmosis filter element 55, and the waste water path 7 can be used to discharge waste water in the reverse osmosis filter element 55.

[0054] Continue to refer to Figure 1The water inlet pump 52 is used to pump the water into the water inlet 21, so that the water can be output after flowing through the first heating water path 2, the second heating water path 4, the first water passing path 25, the second water passing path 43 and the like. The water quality of the water inlet 21 can be detected, and when the water quality is unqualified, the water can be returned to the front filter element 54 through the closing of the first valve body 26 and the opening of the return valve 581, so that the water can pass through the front filter element 54, the reverse osmosis filter element 55 and the rear filter element 56 again, thereby ensuring the water quality of the water supply system 1.
