[0030] With the improvement of income level, people have higher requirements for the quality of life, and drinking water machine is welcomed by the majority of users because it can output drinking water with temperature meeting the needs of users immediately. In order to improve energy utilization, a heat exchange water tank for storing hot water normally is provided in part of the drinking water machines. While the high-temperature water in the heat exchange water tank flows out, low-temperature water will also be supplemented into the heat exchange water tank. However, due to the pressure of water circulation, the low-temperature water supplemented into the heat exchange water tank will impact the remaining high-temperature water in the heat exchange water tank, resulting in the overall cooling of the water body in the heat exchange water tank, and the heat exchange water tank can no longer output high-temperature water meeting the needs of users, which greatly affects the usability of the drinking water machine.

[0031] To improve or solve the above technical problems, the inventors of the present application have conducted long-term research and propose at least the following embodiments.

Figure 1 In the figure, curve A is the temperature of the heat exchange medium entering the first circulating water path from the heating cavity 31. Curve B is the temperature of the water body after flowing through the second heat exchange water path 22. Curve C is the temperature of the heat exchange medium entering the heating cavity 31 from the first circulating water path. Curve D is the temperature of the water body before entering the second heat exchange water path 22. It is not difficult to see that the temperature of the heat exchange medium and the water body in the second heat exchange water path 22 will change very obviously after the heat exchange process. There is a large temperature difference between the low-temperature heat exchange medium and the high-temperature heat exchange medium. When the two are directly mixed, the temperature of the mixed heat exchange medium cannot meet the demand of heating the water body in the second heat exchange water path 22.

[0033] To solve the above technical problems, the specific embodiment of the present application provides a technical scheme, referring to Figures 2-7 , Figure 3 is a schematic diagram of an assembly structure of an embodiment of the water supply system of the present application. Figure 4 is Figure 3 is a schematic diagram of a sectional assembly structure of an embodiment of the section A-A shown in the figure. Figure 5 is a schematic diagram of a water baffle structure of the first embodiment of the water supply system of the present application.

Figure 7 is a schematic diagram of a sectional structure of the section C-C shown in the figure. Figure 3Another embodiment of the cross-sectional view of the cross-sectional assembly structure shown in A-A. The technical solution is specifically to provide a water supply system 1, which comprises a heat exchange device 2, a heat exchange water tank 3, a water baffle 4 and a heating element. The heat exchange device 2 is provided with a first heat exchange water path 21 and a second heat exchange water path 22, and the first heat exchange water path 21 is isolated from the second heat exchange water path 22 and is in thermal connection. The heat exchange water tank 3 is provided with a heating cavity 31, a water inlet 32 and a water outlet 33, the water inlet 32 is arranged at or near one end of the heat exchange water tank 3, and the water inlet 32 is connected with one end of the first heat exchange water path 21 and the heating cavity 31. The water outlet 33 is arranged at or near the other end of the heat exchange water tank 3, and the water outlet 33 is connected with the other end of the first heat exchange water path 21 and the heating cavity 31. The water baffle 4 is arranged in the heat exchange water tank 3, and the water baffle 4 is located between the water inlet 32 and the water outlet 33, and the water baffle 4 is provided with a water passing channel 41 between the water baffle 4 and the inner wall of the heat exchange water tank 3 and / or the water baffle 4, and the water passing channel 41 can communicate the water inlet 32 and the water outlet 33. The heating element is used for heating the heat exchange medium in the heating cavity 31.

[0034] In the structure provided in the specific embodiment, by arranging the water baffle 4 in the heat exchange water tank 3, the lower temperature heat exchange medium input from the water inlet 32 can only flow to the water outlet 33 through the water passing channel 41, and the water baffle 4 forms a certain block to the lower temperature heat exchange medium entering the heating cavity 31 from the water inlet 32, reduces the impact of the lower temperature heat exchange medium on the higher temperature heat exchange medium about to enter the first heat exchange water path 21 through the water outlet 33, and gradually warms up the lower temperature heat exchange medium in the process of flowing to the water outlet 33 through the water passing channel 41, thereby forming a stable temperature transition between the water inlet 32 and the water outlet 33 of the heat exchange water tank 3, reducing the probability that the output heat exchange medium temperature of the heating cavity 31 is too low to meet the heat exchange demand, providing guarantee for the heating effect of the flowing water in the second heat exchange water path 22, and improving the availability and stability of the water supply system 1.

[0035] In a specific embodiment of the present application, referring to Figure 4 、 Figure 7 , the water baffle 4 is arranged in the heat exchange water tank 3 and close to one end of the water inlet 32, and the water passing channel 41 is arranged in a staggered manner with the water inlet 32. In the vertical direction, the water outlet 33 is higher than the water inlet 32.

[0036] In the structure provided in the specific embodiment, the water passing channel 41 is arranged in a staggered manner with the water inlet 32, which can avoid the low-temperature heat exchange medium input from the water inlet 32 to a certain extent, so that the low-temperature heat exchange medium input from the water inlet 32 is temporarily blocked by the water baffle 4, and gradually warms up in the process of moving to the water passing channel 41 and then passing through the water passing channel 41 to the water outlet 33, so that the temperature of the heat exchange medium at each position in the heating cavity 31 is naturally transitioned, the impact of the low-temperature heat exchange medium on the temperature of the heat exchange medium output from the water outlet 33 is reduced, the temperature of the heat exchange medium input into the first heat exchange waterway 21 is relatively stable, and the stability of the water supply system 1 can be improved.

[0037] In the specific embodiment of the present application, referring to Figures 4-7 , the water passing channel 41 can include at least one through hole, and the through hole is arranged on the water baffle 4.

[0038] In the structure provided in the specific embodiment, the water passing channel 41 is arranged on the water baffle 4 in the form of a through hole, and the low-temperature heat exchange medium input from the water inlet 32 can flow to the water outlet 33 through the water passing channel 41 when flowing through the water baffle 4. The through hole has the effect of controlling the flow rate, and at the same time, the flow direction of the heat exchange medium is restricted, so that the temperature of the heat exchange medium in the heating cavity 31 presents a smooth transition from the water inlet 32 to the water outlet 33, and the stability of the water supply system 1 can be improved.

[0039] In the specific embodiment of the present application, referring to Figures 4-7 , the through hole can specifically include an arc-shaped hole 411, and the centers of the plurality of arc-shaped holes 411 coincide with the axis of the heating cavity 31.

[0040] In the structure provided in the specific embodiment, the through hole is specifically a plurality of arc-shaped holes 411 which are symmetrically arranged with respect to the center of the axis of the heating cavity 31, so that the heat exchange medium flows from the water inlet 32 to the water outlet 33 through the arc-shaped holes 411, the temperature of the heat exchange medium in the heating cavity 31 presents a smooth transition from the water inlet 32 to the water outlet 33, and the stability of the water supply system 1 can be improved.

[0041] Further, the plurality of arc-shaped holes 411 on the same circumference can be symmetrically arranged with respect to the center of the axis on the water baffle 4. The heat exchange medium in the heating cavity 31 can flow uniformly along the axial direction of the heating cavity 31, the temperature of the heat exchange medium on the same plane perpendicular to the axial direction tends to be consistent, the temperature transition of the heat exchange medium in the heating cavity 31 is more uniform, and the stability of the water supply system 1 can be improved.

[0042] Specifically, the plurality of arc-shaped holes 411 can have different radii, such as Figure 4 , Figure 5As shown, the plurality of arc-shaped holes 411 in the embodiment have two different radii respectively, the arc-shaped holes 411 with different radii are located on two circumferences with the axis of the heating cavity 31 as the center, and present an outward diffusion structure, which can further improve the uniformity of the heat exchange medium flowing from the water inlet 32 to the water outlet 33 through the arc-shaped holes 411, reduce the probability of unstable local heat exchange medium flow property, maintain the smooth transition of the heat exchange medium temperature in the heating cavity 31 gradually increasing from the water inlet 32 to the water outlet 33, and improve the stability of the water supply system 1.

[0043] In an embodiment of the present application, as shown in Figures 4-6 , the heat exchange water tank 3 comprises a limiting pin 34 arranged in the axial direction X of the parallel heating cavities 31, the limiting pin 34 is provided with a limiting hole 341, the water baffle 4 is provided with a through hole 42 parallel to the limiting pin 34, and the water baffle 4 is further provided with an abutting portion 43, the through hole 42 is used for penetrating the limiting pin 34, the limiting hole 341 is used for accommodating the abutting portion 43, and the limiting pin 34, the limiting hole 341, the through hole 42 and the abutting portion 43 are symmetrically arranged relative to the axial direction X of the heating cavity 31.

[0044] In the structure provided in the embodiment, the through hole 42 can cooperate with the limiting pin 34, can guide the assembly of the water baffle 4 and the heat exchange water tank 3 during installation, when the water baffle 4 and the heat exchange water tank 3 are assembled in place, the abutting portion 43 is aligned with the limiting hole 341, at this time the water baffle 4 can rotate in the axial direction X of the heating cavity 31, so that the abutting portion 43 is accommodated in the limiting hole 341, the water baffle 4 is limited along the axial direction X of the heating cavity 31, the effect of fixing the distance between the water baffle 4, the water inlet 32 and the water outlet 33 is achieved, the probability of displacement of the water baffle 4 under the impact of the heat exchange medium is reduced, and the stability of the water supply system 1 is improved.

[0045] In an embodiment of the present application, referring to Figure 4 , the number of limiting holes 341 can be multiple, and the multiple limiting holes 341 are arranged at the limiting pin 34 in the axial direction X of the heating cavity 31.

[0046] In the structure provided in the embodiment, due to the existence of the multiple limiting holes 341 in the axial direction X of the heating cavity 31, the water baffle 4 can be limited at different positions of the limiting pin 34 according to actual use requirements, thereby adjusting the distance between the water baffle 4, the water inlet 32 and the water outlet 33, and improving the flexibility of the water baffle 4. In addition, multiple water baffles 4 can also be arranged at different positions of the limiting hole 341, and the multiple water baffles 4 cooperate with each other, which can further help to maintain the smooth transition of the heat exchange medium temperature in the heating cavity 31 gradually increasing from the water inlet 32 to the water outlet 33, thereby improving the stability of the water supply system 1.

[0047] In an embodiment of the present application, referring to Figure 4、 Figure 7 The plurality of water baffles 4 are arranged in sequence between the water inlet 32 and the water outlet 33 along the axial direction X of the heating cavity 31. In the structure provided in the embodiment, the plurality of water baffles 4 cooperate to guide the flow direction of the heat exchange medium at different positions in the heating cavity 31, thereby further facilitating the heat exchange medium in the heating cavity 31 to present a smooth transition of gradually increasing temperature from the water inlet 32 to the water outlet 33, thereby improving the stability of the water supply system 1.

[0048] In an embodiment of the present application, as shown in Figure 7 , the plurality of water baffles 4 are arranged at intervals and fixedly connected to each other. In the structure provided in the embodiment, the plurality of water baffles 4 are arranged at intervals and fixedly connected to each other, that is, even if the water baffles 4 are not fixed to the heat exchange tank, due to the connection relationship between the water baffles 4, the distance between the plurality of water baffles 4 can be kept fixed, thereby avoiding the plurality of water baffles 4 from being stacked near the water outlet 33 under the impact of the heat exchange medium, achieving the effect of stabilizing the distance between the water baffles 4 and the water inlet 32 and the water outlet 33, reducing the probability of displacement of the water baffles 4 under the impact of the heat exchange medium, and facilitating the heat exchange medium in the heating cavity 31 to present a smooth transition of gradually increasing temperature from the water inlet 32 to the water outlet 33, thereby improving the stability of the water supply system 1.

[0049] In an embodiment of the present application, referring to Figure 4 、 Figure 7 The heat exchange water tank 3 further comprises a water taking pipe 35 arranged at the top of the heat exchange water tank 3, one end of the water taking pipe 35 extends into the heating cavity 31 in parallel with the axial direction X of the heating cavity 31, and the other end is provided with the water outlet 33. The top of the heat exchange water tank 3 is further provided with an exhaust hole 36. The one end of the water taking pipe 35 extending into the heating cavity 31 is located on the side of the water baffles 4 away from the water inlet 32.

[0050] Since the bubbles have a small density, they generally rise to the top of the heating cavity 31. In the structure provided in the embodiment, the water taking pipe 35 extending into the heating cavity 31 can be used to obtain high-temperature heat exchange medium from the heating cavity 31 into the first heat exchange water passage 21, which can reduce the probability of bubbles in the heating cavity 31 entering the first heat exchange water passage 21, thereby reducing the adverse effects of bubbles on the heat exchange efficiency of the heat exchange device 2. In addition, the heat exchange water tank 3 is further provided with the exhaust hole 36, and the bubbles in the heating cavity 31 can be discharged through the exhaust hole 36. The exhaust hole 36 and the water taking pipe 35 cooperate to effectively maintain the heat exchange efficiency of the water supply system 1, thereby improving the stability and usability of the water supply system 1.

[0051] To solve the above technical problems, the specific embodiment of the present application further provides a drinking water machine, comprising a water outlet component and the water supply system 1 as described in any one of the above specific embodiments. The water outlet component can comprise a heater 52 and a water outlet waterway 51, the heater 52 being connected to the water outlet waterway 51, and the water outlet waterway 51 being connected to the second heat exchange waterway 22 of the water supply system 1.

[0052] In the structure provided in the specific embodiment, by arranging the water baffle 4 in the heat exchange water tank 3, the lower-temperature heat exchange medium input from the water inlet 32 can only flow to the water outlet 33 through the water passing channel 41, the lower-temperature heat exchange medium entering the heating cavity 31 from the water inlet 32 is blocked to some extent, the impact of the lower-temperature heat exchange medium on the higher-temperature heat exchange medium about to enter the first heat exchange waterway 21 through the water outlet 33 is reduced, the lower-temperature heat exchange medium is gradually heated in the process of flowing to the water outlet 33 through the water passing channel 41, thereby forming a stable temperature transition between the water inlet 32 and the water outlet 33 of the heat exchange water tank 3, the probability that the heating cavity 31 outputs heat exchange medium with a temperature that is too low to meet the heat exchange requirement is reduced, the heating effect of the water flowing in the second heat exchange waterway 22 is guaranteed, and the usability and stability of the drinking water machine are greatly improved.

[0053] After the water supply system 1 completes the heat exchange process, the water body entering the water outlet waterway 51 from the second heat exchange waterway 22 can be further heated by the heater 52. And because the water body has been preheated once in the second heat exchange waterway 22, the heat required to further increase the temperature of the water body to the water temperature required by the user is reduced, so that even if the power of the heater 52 is limited, the water outlet of the drinking water machine can still quickly reach the water temperature required by the user with the help of the water supply system 1.
