It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0030] As income levels rise, people have higher demands for quality of life. Instantaneous hot water dispensers are popular because they can instantly provide users with drinking water at the desired temperature. However, due to inherent power limitations, instantaneous hot water dispensers have limited heating efficiency. When users need a large amount of hot water, the heating speed cannot keep up with the output speed, requiring users to wait for a certain amount of time to obtain sufficient drinking water. This results in the inability to meet users' water needs promptly, contradicting the convenient nature of instantaneous hot water dispensers and significantly impacting their usability.
[0031] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.
[0032] To address the aforementioned technical problems, this application provides a specific implementation method, see reference. Figures 1-7 , Figure 1 This is a schematic diagram of the assembly structure of a specific embodiment of the water supply system provided in this application. Figure 2 This is a schematic diagram of the assembly structure of another specific embodiment of the water supply system provided in this application. Figure 3 This is a schematic diagram of the assembly structure of a specific embodiment of the water supply system provided in this application from another angle. Figure 4 yes Figure 3 A schematic diagram of the cross-sectional structure shown in section AA. Figure 5 yes Figure 2 A schematic diagram of the cross-sectional structure shown in section BB. Figure 6 yes Figure 3 A schematic diagram of the cross-sectional structure shown in section CC. Figure 7 This is a schematic block diagram of the water circuit structure of a specific embodiment of the water supply system provided in this application. This specific embodiment provides a water supply system 1, which includes a heating element 2, a heat exchange device 3, and a second hot water exchange path 4. The heat exchange device 3 includes a heat exchange chamber 31 and a first hot water exchange path 32. The first hot water exchange path 32 has a first inlet 321 and a first outlet 322. The heat exchange chamber 31 has a second inlet 311 and a second outlet 312. The first inlet 321 is connected to the second outlet 312, and the first outlet 322 is connected to the second inlet 311. The heating element 2 can be used to heat the heat exchange medium in the heat exchange chamber 31. The second hot water exchange path 4 is isolated from the first hot water exchange path 32, and the second hot water exchange path 4 is thermally connected to the first hot water exchange path 32.
[0033] In the structure provided in this specific embodiment, by setting up a heat exchange device 3, energy is stored in the form of a heat exchange medium in the heat exchange cavity 31. The heat exchange medium circulates through the heat exchange cavity 31 and the first heat exchange water path 32, and the first heat exchange water path 32 is thermally connected to the second heat exchange water path 4. The high-temperature heat exchange medium in the first heat exchange water path 32 can exchange heat with the water flowing in the second heat exchange water path 4 in a heat exchange manner, thereby rapidly heating the water flowing in the second heat exchange water path 4, alleviating the limitation of the heating power of the water supply system 1 on the amount of hot water used and the efficiency of hot water use, and has extremely high practicality.
[0034] Optionally, the heating element 2 may be housed within the heat exchange chamber 31. Further, the heating element 2 may be located between the second inlet 311 and the second outlet 312.
[0035] In a specific embodiment of this application, see [reference]. Figures 1-6 The water supply system 1 also includes a first water pipe 33, a second water pipe 41, and a pump body 6. The second water pipe 41 has a third inlet 411 and a third outlet 412. The first water pipe 33 and the second water pipe 41 are thermally connected. A first heat exchange passage 32 is formed in the pipe of the first water pipe 33. A first inlet 321 and a first outlet 322 are located at both ends of the first water pipe 33. A second heat exchange passage 4 is formed in the pipe of the second water pipe 41. The pump body 6 is connected to the heat exchange device 3 and can be used to drive the heat exchange medium to flow in the first heat exchange passage 32 and the heat exchange chamber 31.
[0036] The direction along the second hot water exchange path 4 from the third inlet 411 to the third inlet 411 is defined as the first direction, and the pump body 6 is used to pump the heat exchange medium in the first hot water exchange path 32 in the opposite direction to the first direction.
[0037] In the structure provided in this specific embodiment, the first water pipe 33 and the second water pipe 41 are thermally connected. The first hot water exchange path 32 is formed inside the first water pipe 33. The heat exchange medium heated to a higher temperature by the heating element 2 in the heat exchange chamber 31 can enter the first water pipe 33 from the first inlet 321 under the action of the pump body 6, thereby exchanging heat with the water in the second water pipe 41 to heat the water. After exchanging heat with the water, the temperature of the heat exchange medium in the first water pipe 33 will drop. Under the action of the pump body 6, the cooled heat exchange medium can return from the first outlet 322 to the heat exchange chamber 31 to be reheated by the heating element 2 for heat storage, thereby realizing a temperature cycle of heat storage, heat exchange, and re-storage. Furthermore, the continuous flow of the heat exchange medium in the first hot water exchange path 32 can be ensured by the action of the pump body 6, and the heat exchange efficiency between the first hot water exchange path 32 and the second hot water exchange path 41 can increase the efficiency of heating the water flowing through the second hot water exchange path 41.
[0038] Optionally, see Figures 1-3 Specifically, the first water pipe 33 and the second water pipe 41 can be coiled together. Due to their coiled arrangement, the surface area of the heat-conducting connection between the first water pipe 33 and the second water pipe 41 is greatly increased, thereby increasing the contact area where heat exchange can occur between the first hot water exchange circuit 32 and the second hot water exchange circuit 4. This improves the heat exchange efficiency between the first hot water exchange circuit 32 and the second hot water exchange circuit 4, further increasing the efficiency of heating the water flowing through the second hot water exchange circuit 4, and greatly enhancing the availability of the water supply system 1.
[0039] Optionally, the heat exchange medium in the first heat exchange circuit 32 and the water in the second heat exchange circuit 4 can flow in opposite directions, so that the temperature change trends in the first heat exchange circuit 32 and the second heat exchange circuit 4 are opposite. The high-temperature heat exchange medium that has just flowed into the first heat exchange circuit 32 can form a temperature difference with the high-temperature water that is about to be output from the second heat exchange circuit 4 for heat exchange, and the low-temperature heat exchange medium that is about to flow out of the first heat exchange circuit 32 can also form a temperature difference with the low-temperature water that has just entered the second heat exchange circuit 4 for heat exchange. This can ensure the efficiency of the entire heat exchange process and greatly improve the availability of the water supply system 1.
[0040] For example, the heat exchange effect can be obtained by using the water supply system 1 structure provided in this application. When the heat exchange medium in the heat exchange chamber 31 is maintained at 90~95°C, the water in the second heat exchange channel 4 can be heated from about 25°C to about 75°C when it flows through the heat exchange, while the heat exchange medium in the first heat exchange channel 32 will drop from about 90°C to about 35°C.
[0041] In a specific embodiment of this application, see [reference]. Figure 4 , Figure 5 The heat exchange chamber 31 is located inside the hot water tank 5. The second inlet 311 and the second outlet 312 are located in the hot water tank 5. The first water pipe 33 and the second water pipe 41 are coiled on the surface of the hot water tank 5 away from the heat exchange chamber 31. The hot water tank 5 is thermally connected to the first water pipe 33.
[0042] In the structure provided in this specific embodiment, the first water pipe 33 and the second water pipe 41 are coiled around the outer peripheral surface of the hot water exchange tank 5. The first water pipe 33, which is thermally connected to the hot water exchange tank 5, allows the heat exchange medium in the first hot water exchange path 32 to absorb the heat lost from the heat exchange cavity 31. It can also conduct this heat to the water in the second hot water exchange path 4 through the second water pipe 41, which is thermally connected to the first water pipe 33. Furthermore, the temperature of the first water pipe 33 and the second water pipe 41 coiled around the outside is usually higher than the ambient temperature. The first water pipe 33 and the second water pipe 41 can also keep the heat exchange cavity 31 warm, slow down the rate at which the heat stored in the heat exchange cavity 31 is lost to the outside, and can reuse some of the heat flowing out of the heat exchange cavity 31, which can effectively improve the energy utilization rate of the water supply system 1.
[0043] In a specific embodiment of this application, see [reference]. Figure 4 , Figure 5 The second outlet 312 and the second inlet 311 can be respectively set at both ends of the hot water exchange tank 5. The first water pipe 33 and the second water pipe 41 are coiled around the end of the hot water exchange tank 5 where the second outlet 312 is located.
[0044] In the structure provided in this specific embodiment, the second inlet 311 for inputting the low-temperature heat exchange medium and the second outlet 312 for outputting the high-temperature heat exchange medium are located at both ends of the hot water tank 5. Due to the temperature transition between the second outlet 312 and the second inlet 311, the two ends of the hot water tank 5 exhibit different temperatures. The first water pipe 33 and the second water pipe 41 are coiled around the end of the hot water tank 5 with the second outlet 312 and the higher temperature end can effectively absorb the heat lost from the heat exchange cavity 31 and provide insulation for the high-temperature part of the heat exchange cavity 31. At the same time, the lower temperature end of the heat exchange cavity 31 will not have an adverse effect on the high-temperature heat exchange medium in the first water pipe 33 or the high-temperature water in the second water pipe 41, which greatly improves the stability of the water supply system 1.
[0045] Optionally, in the vertical direction, the second outlet 312 can be higher than the second inlet 311. As the temperature rises, the movement of matter tends to be more intense. The density of hot water is slightly less than that of cold water. Therefore, within the heat exchange chamber 31, the heat exchange medium with a higher temperature will naturally move to the upper part of the heat exchange chamber 31, while the heat exchange medium with a lower temperature will naturally sink to the bottom of the heat exchange chamber 31. Setting the second outlet 312 higher than the second inlet 311 conforms to the natural temperature transition trend within the heat exchange chamber 31, which can prevent the input of the low-temperature heat exchange medium from causing excessive impact on the high-temperature heat exchange medium, maintain the stable temperature of the heat exchange medium input to the first hot water exchange path 32, and improve the availability of the water supply system 1.
[0046] In one specific embodiment of this application, the hot water exchange tank 5 includes a first tank 51 and a second tank 52, which are horizontally connected. A second inlet 311 is located at the end of the first tank 51 away from the second tank 52, and a second outlet 312 is located at the end of the second tank 52 away from the first tank 51. The heating element 2 is connected to the first tank 51, and the first hot water exchange path 32 and the second circulating water path are coiled around the second tank 52.
[0047] In the structure provided in this specific embodiment, the first housing 51 and the second housing 52 form a horizontal temperature transition between the second inlet 311 and the second outlet 312, which further maintains the temperature difference between different positions of the heat exchange chamber 31, keeps the temperature of the heat exchange medium input into the first heat exchange circuit 32 stable, and improves the stability of the water supply system 1.
[0048] In a specific embodiment of this application, see [reference]. Figures 4-6 The first water pipe 33 can be sleeved on the outer periphery of the second water pipe 41. The inner surface of the first water pipe 33 and the outer surface of the second water pipe 41 form the first hot water exchange circuit 32. The pipe of the second water pipe 41 is the second hot water exchange circuit 4.
[0049] The second water pipe 41 can also be sleeved around the outer periphery of the first water pipe 33. The inner surface of the first water pipe 33 and the outer surface of the second water pipe 41 form a second hot water exchange circuit 4. The pipe of the first water pipe 33 is the first hot water exchange circuit 32.
[0050] In the structure provided by this specific embodiment, the first water pipe 33 and the second water pipe 41 are connected to each other. One of the first water pipe 33 and the second water pipe 41 is installed inside the other pipe. The outer surface of the one installed inside the pipe can directly contact the water or heat exchange medium in the other to exchange heat, which significantly increases the thermally conductive connection area between the first heat exchange water circuit 32 and the second heat exchange water circuit 4, thereby improving the heat exchange efficiency of the first heat exchange water circuit 32 and the second heat exchange water circuit 4.
[0051] See Figure 5 Taking the first water pipe 33 being sleeved around the second water pipe 41 as an example, while the heat exchange medium in the first water pipe 33 heats the water in the second water pipe 41 through heat exchange, the water in the second water pipe 41 that needs to be heated will be surrounded by the heat exchange medium in the first water pipe 33 in terms of spatial distribution. The heat is not easily lost, which has the effect of heat preservation on the water in the second water pipe 41, reducing the heat overflowing from the second water pipe 41 and improving the energy utilization rate of the water supply system 1.
[0052] Similarly, when the second water pipe 41 is installed around the first water pipe 33, the water in the second water pipe 41 can also spatially surround the heat exchange medium in the first water pipe 33, thereby reducing the heat lost from the first water pipe 33 to the outside, and playing a heat preservation effect on the heat exchange medium in the first water pipe 33, reducing the heat overflow from the first water pipe 33, and improving the energy utilization rate of the water supply system 1.
[0053] It is understandable that the first hot water exchange circuit is the gap formed between the inner surface of the first water pipe 33 and the outer surface of the second water pipe 41. If heat is transferred from the gap to the cavity of the second water pipe 41 (the inner layer pipe), the range of water that needs to be transferred gradually decreases. However, if heat is transferred from the cavity of the second water pipe 41 to the gap, the range of water that needs to be transferred gradually increases. Comparing the two, it is understandable that the former heat transfer method makes it easier for heat to accumulate, which helps to achieve high-efficiency heat exchange.
[0054] Furthermore, such as Figure 5 , 6 As shown, a stepped structure can be formed between the first box 51 and the second box 52. The bottom of the second box 52 is higher than the first box 51, that is, the heat exchange chamber 31 is a stepped chamber. The stepped structure is used to prevent the low-temperature heat exchange medium that has just entered the bottom of the first box 51 from entering the second box 52.
[0055] In one specific embodiment of this application, such as Figure 5 As shown, the heat exchange tank 5 may also include a guide pipe 53. One end of the guide pipe 53 is connected to the first outlet 322, and the other end is provided with a second inlet 311. The guide pipe 53 extends at least partially into the heat exchange chamber 31 and is located near the heating element 2. The end of the guide pipe 53 with the second inlet 311 is away from the second outlet 312.
[0056] In the structure provided in this specific embodiment, the guide pipe 53 can guide the low-temperature heat exchange medium returning to the heat exchange chamber 31 to a position away from the second outlet 312 and closer to the heating element 2, reducing the probability that this part of the low-temperature heat exchange medium will directly contact the high-temperature heat exchange medium in the heat exchange chamber 31, causing a significant drop in the temperature of the high-temperature heat exchange medium in the heat exchange chamber 31, thereby adversely affecting the heating effect of the water in the second hot water circuit 4. At the same time, the guide pipe 53 is immersed in the heat exchange medium in the heat exchange chamber 31, and the low-temperature heat exchange medium in the guide pipe 53 can also gradually heat up as it flows along the guide pipe 53 towards the second inlet 311, mitigating the impact on the temperature of the heat exchange medium in the heat exchange chamber 31 caused by the direct entry of the low-temperature heat exchange medium into the heat exchange chamber 31, and improving the stability of the water supply system 1.
[0057] In one specific embodiment of this application, the first hot water exchange path 32 is connected to the heat exchange chamber 31 and is thermally connected to the heat exchange chamber 31.
[0058] In the structure provided in this specific embodiment, the first hot water exchange path 32 is connected to the heat exchange chamber 31 and is thermally connected to the heat exchange chamber 31. The heat of the heat exchange medium in the heat exchange chamber 31 can be transferred to the heat exchange medium in the first hot water exchange path 32 through thermal conduction, which has a heat preservation effect on the heat exchange medium in the first hot water exchange path 32, slows down the cooling rate of the heat exchange medium in the first hot water exchange path 32 due to the heat exchange process, increases the temperature difference between the heat exchange medium and the flowing water in the second hot water exchange path 4, and can further increase the efficiency of heating the flowing water in the second hot water exchange path 4, greatly improving the availability of the water supply system 1.
[0059] In one specific embodiment of this application, such as Figure 4 As shown, the water supply system 1 may also include a baffle plate 7, which is vertically arranged in the heat exchange chamber 31. The second inlet 311 and the second outlet 312 are located on both sides of the baffle plate 7, and the baffle plate 7 and the inner wall of the heat exchange chamber 31 and / or the baffle plate 7 are provided with a water passage 71 that connects the second inlet 311 and the second outlet 312.
[0060] In the structure provided in this specific embodiment, the baffle plate 7 can isolate the low-temperature heat exchange medium input into the second inlet 311 from the high-temperature heat exchange medium near the second outlet 312 to a certain extent, avoiding rapid temperature cross-contamination between the two sides. The low-temperature heat exchange medium can gradually heat up as it flows through the water passage 71 to the second outlet 312, keeping the temperature of the heat exchange medium input into the first hot water exchange circuit 32 stable and improving the stability of the water supply system 1.
[0061] Optionally, the water supply system 1 may further include a water supply pipe 54 and a drain pipe 55. One end of the water supply pipe 54 is connected to the heat exchange chamber 31 for supplying heat exchange medium into the heat exchange chamber 31. The water supply pipe 54 may be located near the heating element 2, or in the middle and / or bottom of the heat exchange chamber 31, so that the low-temperature heat exchange medium supplied into the heat exchange chamber 31 can be heated by the heating element 2 without affecting the temperature of the heat exchange medium output from the second outlet 312 to the first hot water exchange circuit 32.
[0062] One end of the drain pipe 55 is connected to the heat exchange chamber 31 to drain the heat exchange medium and / or air bubbles inside the heat exchange chamber 31. The drain pipe 55 can be located at the top or upper part of the heat exchange chamber 31 to facilitate the drainage of air bubbles. When the temperature of the heat exchange medium inside the heat exchange chamber 31 is too high, the drain pipe 55 can drain the high-temperature heat exchange medium, reducing the probability of equipment overheating and improving stability.
[0063] To address the aforementioned technical problems, this application also provides a drinking water dispenser, including a water outlet component and a water supply system 1 as described in any of the above embodiments. The water outlet component may include a heater and a water outlet path, with the heater connected to the water outlet path and the water outlet path connected to a second hot water exchange path 4 of the water supply system 1.
[0064] By setting up a heat exchange device 3 and using the heat exchange chamber 31 to store energy in the form of hot water, and by using the first hot water exchange path 32 and the second hot water exchange path 4 for thermal connection, a large amount of water flowing through the second hot water exchange path 4 can be rapidly heated by heat exchange, which alleviates the limitation of the heating power of the water supply system 1 on the amount and efficiency of hot water consumption. Since the first hot water exchange path 32 and the heat exchange chamber 31 are also thermally connected, a large amount of hot water in the heat exchange chamber 31 can have a heat preservation effect on the heat exchange medium in the first hot water exchange path 32, slowing down the rate at which the heat exchange medium in the first hot water exchange path 32 cools down during the heat exchange process, increasing the temperature difference between the heat exchange medium and the water flowing through the second hot water exchange path 4, and further increasing the efficiency of heating the water flowing through the second hot water exchange path 4, which greatly improves the usability of the drinking water machine.
[0065] After the heat exchange process is completed in the water supply system 1, the water entering the outlet water circuit from the second heat exchange water circuit 4 can be further heated by the heater. Since the water has already been preheated once in the second heat exchange water circuit 4, the amount of heat required to further raise the water temperature to the user's required temperature is reduced. Even if the heater power is limited, the water dispenser can still quickly reach the user's required water temperature with the help of the water supply system 1.
