[0002] Refrigerated water equipment can prepare water bodies with temperatures lower than normal temperature, which can meet the user's demand for low-temperature water bodies. Therefore, refrigerated water equipment is becoming more and more common in both commercial and household scenarios.

[0003] In refrigerated water equipment, while the refrigerating component cools the water body, it also generates heat.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0025] Refrigerated water equipment can prepare water bodies with temperatures lower than normal temperature, which can meet the user's demand for low-temperature water bodies. Therefore, refrigerated water equipment is becoming more and more common in both commercial and household scenarios.

[0026] In refrigerated water equipment, while the refrigerating element cools the water body, it also generates heat, and the heat generation phenomenon of the refrigerating element will affect its refrigeration efficiency. In order to ensure the efficiency of refrigerated water, a heat dissipation structure is usually provided for the heat-generating part of the refrigerating element, and the heat dissipation structure is used to dissipate heat from the refrigerating element to improve the working efficiency of the refrigerating element, ensuring that the refrigerated water equipment can effectively provide cold water to users. However, this part of the heat taken away by the heat dissipation structure usually cannot be effectively utilized, but is directly dissipated or discharged, greatly reducing the energy utilization rate of the refrigerated water equipment.

[0027] In order to improve or solve the above technical problems, the inventors of the present application have conducted long-term research and proposed at least the following embodiments.

[0028] Refer to Figure 1 , Figure 1It is a schematic diagram of the water circuit structure of the first embodiment of the chilled water equipment provided by this application. The specific implementation of this application can provide a chilled water equipment 1, which can be used to prepare water with a temperature lower than normal temperature.

[0029] The chilled water equipment 1 can include a water inlet pipeline 2, a filter element 3, a refrigerating element 4, a refrigerating water circuit 5, and a heat exchange water circuit 6. The filter element 3 is provided with a water inlet end 31 and a water outlet end 32. The refrigerating element 4 is provided with a refrigerating part 41 and a heating part 42. The refrigerating water circuit 5 is at least connected to the water outlet end 32, and the refrigerating water circuit 5 is thermally connected to the refrigerating part 41. The heat exchange water circuit 6 is connected to the water inlet pipeline 2 or the heat exchange water circuit 6 is connected to the water outlet end 32 and the water inlet pipeline 2. The heat exchange water circuit 6 can include a circulating water circuit 61 and / or a heat exchange water cavity 62, and at least one of the circulating water circuit 61 and the heat exchange water cavity 62 is thermally connected to the heating part 42. The water inlet pipeline 2 passes through the heating part 42 and is connected to the water inlet end 31. A first return water circuit 91 is connected between the water outlet end 32 and the water inlet pipeline 2 for allowing the water flowing out from the water outlet end 32 to flow through the heating part 42.

[0030] In the structure provided by this specific implementation, by setting the water inlet pipeline 2 and the first return water circuit 91, the heat exchange water flowing through the heating part 42 can be input into the water inlet end 31 of the filter element 3 through the water inlet pipeline 2, and the water output from the water outlet end 32 after being filtered by the filter element 3 can flow through the heating part 42 by using the first return water circuit 91. Moreover, the refrigerating element 4 can also utilize the water body output from the water outlet end 32 of the filter element 3. After the water body exchanges heat by flowing through the heat exchange water circuit 6 and / or the water inlet pipeline 2 and flowing through the heating part 42, it can be used to prepare cold water or be used again for heat exchange with the heating part 42. The heat exchange water generated during the heat exchange process can be effectively recycled, which can reduce the waste of heat exchange water while maintaining the refrigerating efficiency of the refrigerating element 4 through heat exchange, and improve the material utilization rate of the chilled water equipment 1.

[0031] Furthermore, the temperature of the heat exchange water rises after flowing through the heating part 42. When the relatively high-temperature heat exchange water is filtered by the filter element 3, it can conduct heat to the filter element 3, achieving the effect of cooling the heat exchange water and heating the filter element 3. Compared with the heat exchange water that has been circulating in the heat exchange water circuit 6 for heat exchange, the cooled heat exchange water output from the water outlet end 32 can be used again for heat exchange, which can effectively improve the cooling efficiency of the heating part 42. And the viscosity of the water body decreases with the increase of temperature, the molecular movement is more intense, and the speed of passing through the structure of the filter element 3 will also be faster. Therefore, for some types of filter elements 3, appropriately raising the temperature can increase the filtering speed of the filter element 3 for the water body. The heat taken away by the heat exchange water from the heating part 42 can be used to increase the filtering speed of the filter element 3, thereby improving the energy utilization rate of the chilled water equipment 1.

[0032] Specifically, the filter element 3 may include a reverse osmosis filter element, an ultrafiltration filter element, and an ion exchange resin filter element. As the temperature rises, the viscosity of water decreases, molecular diffusion accelerates, the water permeability of the reverse osmosis membrane in the reverse osmosis filter element increases, and the speed at which water passes through the ultrafiltration membrane of the ultrafiltration filter element increases, enabling the reverse osmosis filter element and the ultrafiltration filter element to increase the speed of outputting the filtered water. For the ion exchange resin filter element, the increase in temperature enhances the thermal motion of molecules, which can promote the ion exchange process of the ion exchange resin, thereby improving the filtration speed of the ion exchange resin filter element.

[0033] Refer to Figure 1 , a water inlet pump 22, a water inlet valve 21, and a filtered water inlet valve 23 may be connected in the water inlet pipeline 2. The water inlet valve 21 of the water inlet pump 22 is used to pump the water in the water inlet pipeline 2 to flow through the heating part 42 towards the water inlet end 31 of the filter element 3, and the filtered water inlet valve 23 is used to control whether the water inlet pipeline 2 is communicated with the water inlet end 31 of the filter element 3. When the filtered water inlet valve 23 is disconnected, the water in the water inlet pipeline 2 cannot be input into the filter element 3 through the water inlet end 31.

[0034] When the type of the filter element 3 is a reverse osmosis filter element, the filter element 3 may also have a waste water end 33 for outputting the concentrated water generated by filtration. The waste water end 33 of the filter element 3 may be connected with a filtered waste water pipeline 331. Comparing the water flowing through the water inlet end 31, the water outlet end 32, and the waste water end 33 of the reverse osmosis filter element, the impurity content of the water flowing through the water outlet end 32 is the lowest, followed by the water flowing through the water inlet end 31, and the concentrated water flowing through the waste water end 33 into the filtered waste water pipeline 331 has the highest impurity content. The filtered waste water pipeline 331 may be used to discharge the concentrated water from the chilled water device 1 to prevent the concentrated water from staying in the filter element 3 and affecting the hygiene of the filter element 3.

[0035] Such as Figure 1 shown, a circulation pump 613 and a circulation valve 614 may be connected in the circulation water pipeline 61. The circulation pump 613 is used to promote the circulation of water between the circulation water pipeline 61 and the heat exchange water cavity 62, and the circulation valve 614 is used to control the on-off of the circulation water pipeline 61. When the circulation valve 614 is disconnected, the water in the circulation water pipeline 61 and the heat exchange water cavity 62 cannot continue to circulate, and the water in the water inlet pipeline 2 cannot enter the heat exchange water pipeline 6 either. However, the water in the water inlet pipeline 2 can still flow towards the water inlet end 31 through the heating part 42 without being affected, realizing heat exchange with the heating part 42.

[0036] Optionally, a first return water valve 911 may be connected in the first return water pipeline 91. The first return water valve 911 is used to control the on-off of the first return water pipeline 91. When the first return water valve 911 is disconnected, the water output from the water outlet end 32 cannot flow through the first return water pipeline 91 and pass through the heating part 42 again.

[0037] In a specific embodiment of the present application, refer to Figure 7 ,Figure 7 It is a schematic diagram of the water circuit structure of the fourth embodiment of the refrigerated water equipment provided by this application. The water inlet pipeline 2 may specifically include a bactericidal water inlet path 24 and a bactericidal water outlet path 25. The first end of the bactericidal water inlet path 24 communicates with the heat exchange water path 6, and the second end of the bactericidal water inlet path 24 communicates with the refrigeration water path 5. One end of the bactericidal water outlet path 25 communicates with the refrigeration water path 5, and the other end of the bactericidal water outlet path 25 communicates with the water inlet end 31 and / or the heat exchange water path 6.

[0038] Among them, the heat exchange water path 6 may communicate with the water outlet end 32, so that the water input into the heat exchange water path 6 for use as heat exchange water is all water filtered by the filter element 3, thus having better water quality.

[0039] Optionally, the water inlet pipeline 2 may include a purified water inlet path 26. One end of the purified water inlet path 26 communicates with the heat exchange water path 6, and the other end of the purified water inlet path 26 is used to connect to the water outlet end 32 and / or an external purified water source. Similarly, the water filtered by the filter element 3 or the purified water prepared externally can be used as heat exchange water.

[0040] In the structure provided by this specific embodiment, the heat exchange water with better water quality is input into the refrigeration water path 5 through the bactericidal water inlet path 24, and then the refrigeration water path 5 can be flushed. When the heat exchange water has a relatively high temperature, high-temperature sterilization can also be carried out during flushing, which can effectively clean the refrigeration water path 5, remove the microorganisms and accumulated impurities generated during the use of the refrigeration water path 5, can effectively reuse the heat exchange water, and improve the water quality of the cold water prepared by the refrigeration water path 5.

[0041] The water body for flushing the refrigeration water path 5 can be input into the water inlet end 31 through the bactericidal water outlet path 25 to be filtered by the filter element 3, so that the heat exchange water can be recycled after filtration, and the residual temperature of the heat exchange water can also be used to heat the filter element 3, which can improve the energy utilization rate and material utilization rate of the refrigerated water equipment 1.

[0042] As Figure 1 shown, in a specific embodiment of this application, the refrigeration water path 5 may include a cold water cavity 51, a refrigeration water inlet path 52, and a refrigeration water outlet path 53. The refrigeration water inlet path 52 communicates with the water outlet end 32 and the cold water cavity 51, and the refrigeration water outlet path 53 is used to communicate the cold water cavity 51 and the cold water outlet channel 101. The cold water cavity 51 is thermally connected to the refrigeration unit 41.

[0043] In the structure provided by this specific embodiment, the water outlet end 32 of the filter element 3 is connected to the cold water cavity 51 through the refrigeration water inlet path 52, and the water filtered by the filter element 3 can be input into the cold water cavity 51 for preparing cold water. The water in the cold water cavity 51 can be cooled under the action of the refrigeration unit 41, so that cold water can be prepared and stored in the cold water cavity 51. The cold water in the cold water cavity 51 can enter the cold water outlet channel 101 through the refrigeration water outlet path 53, and then the cold water prepared by the refrigeration water path 5 can be output to the outside for the user to use.

[0044] Optionally, referring to Figure 1 , a refrigeration water inlet valve 521 can be connected in the refrigeration water inlet path 52. The refrigeration water inlet valve 521 can control the on-off of the refrigeration water inlet path 52. When the refrigeration water inlet valve 521 is disconnected, the water output from the water outlet end 32 cannot enter the cold water cavity 51. A cold water pump 531 and a cold water valve 532 can be connected in the refrigeration water outlet path 53. The cold water pump 531 is used to pump the water in the refrigeration water outlet path 53 from the cold water cavity 51 to the cold water outlet channel 101, and the cold water valve 532 is used to control the on-off of the refrigeration water outlet path 53. When the cold water valve 532 is closed, the water in the cold water cavity 51 cannot leave the cold water cavity 51 through the refrigeration water outlet path 53.

[0045] As Figure 1 shown, a cold water outlet valve 101a can also be connected to the cold water outlet channel 101. The cold water outlet valve 101a is used to control the on-off of the cold water outlet channel 101. When the cold water outlet valve 101a is connected, the cold water outlet channel 101 can output the water in the refrigeration water outlet path 53 to provide it to the user. The cold water cavity 51 can be connected with an exhaust path 54. The exhaust path 54 communicates with the top of the cold water cavity 51 and can be used to discharge the bubbles in the cold water cavity 51.

[0046] Furthermore, the refrigeration water outlet path 53 can also be connected to a filtered wastewater path 331. When the cold water outlet valve 101a is closed, the refrigeration water outlet path 53 can input the water in the cold water cavity 51 into the filtered wastewater path 331. When the water in the cold water cavity 51 is stored for too long, microorganisms may breed in it and it is no longer suitable for the user to take. Therefore, this part of the water can be input into the filtered wastewater path 331 and discharged to avoid polluting the cold water outlet channel 101.

[0047] Specifically, in Figure 7In the illustrated embodiment, the sterilization water inlet passage 24 can specifically communicate with the refrigeration water inlet passage 52 of the refrigeration water passage 5, and the sterilization water outlet passage 25 can specifically communicate with the refrigeration water outlet passage 53 of the refrigeration water passage 5. After the heat exchange water enters the refrigeration water inlet passage 52, it flows through the cold water cavity 51 and then enters the sterilization water outlet passage 25 through the refrigeration water outlet passage 53. The water in the sterilization water outlet passage 25 can enter the water inlet end 31 again to be filtered by the filter element 3, which can fully flush and sterilize the cold water cavity 51 for preparing cold water, and the heat exchange water used for sterilization can be filtered and then put to other uses.

[0048] In a specific embodiment of the present application, the cold water cavity 51 can include a refrigeration cavity 511 and a cold storage cavity 512. Refer to Figure 2 , Figure 3 , Figure 2 which is a schematic diagram of the water passage structure of the second embodiment of the refrigeration water equipment provided by the present application. Figure 3 which is a schematic diagram of the water passage structure of the third embodiment of the refrigeration water equipment provided by the present application. Figure 2 shows a possible structure of the refrigeration cavity 511 and the cold storage cavity 512, Figure 3 shows another possible structure of the refrigeration cavity 511 and the cold storage cavity 512. In Figure 2 the refrigeration cavity 511 and the cold storage cavity 512 are arranged vertically, and in Figure 3 the refrigeration cavity 511 and the cold storage cavity 512 are arranged horizontally.

[0049] The refrigeration cavity 511 is used to directly conduct heat connection with the refrigeration part 41 to prepare cold water, and the cold storage cavity 512 is used to store cold water. The refrigeration cavity 511 can be selectively communicated with the cold storage cavity 512. The refrigeration cavity 511 is thermally connected to the refrigeration part 41. The refrigeration water inlet passage 52 communicates with the refrigeration cavity 511, and the refrigeration water outlet passage 53 communicates with the cold storage cavity 512.

[0050] In the structure provided by this specific embodiment, the filtered water output from the water outlet end 32 can be input into the refrigeration cavity 511 for cooling, and by using the selective communication relationship between the refrigeration cavity 511 and the cold storage cavity 512, the water in the cold storage cavity 512 is not directly in contact with the relatively high-temperature water input by the refrigeration water inlet passage 52. After the water in the refrigeration cavity 511 is cooled to the appropriate temperature, the refrigeration cavity 511 and the cold storage cavity 512 are communicated to supplement this part of the water into the cold storage cavity 512, which can keep the water in the cold storage cavity 512 at a relatively low temperature all the time, so that the temperature of the water output from the cold storage cavity 512 through the refrigeration water outlet passage 53 is relatively stable and will not be too high to meet the user's usage requirements.

[0051] Especially for the case where the water output from the water outlet 32 has been used for heat exchange, even if the temperature of the water after heat exchange with the heating part 42 is slightly reduced after being filtered by the filter element 3, it is still higher than the cold water in the cold storage chamber 512. Such water directly contacts with cold water, which will cause a significant change in the temperature of the cold water. If the refrigeration chamber 511 is not used to achieve the transition between it and the cold storage chamber 512, the temperature of the cold water in the cold water outlet channel 101 input by the refrigeration water circuit 5 will increase sharply, seriously affecting the availability of the refrigeration water equipment 1.

[0052] At the same time, after separating the refrigeration chamber 511 and the cold storage chamber 512 into two areas, only the water in the refrigeration chamber 511 directly exchanges heat with the refrigeration unit 41, and the total volume of the water directly exchanging heat is reduced, so the cooling speed of the water also becomes faster. While the cold water in the cold storage chamber 512 is output to the cold water outlet channel 101, the refrigeration chamber 511 can quickly prepare and replenish cold water into the cold storage chamber 512, and the preparation and use of cold water do not interfere with each other.

[0053] Specifically, see Figure 2 , Figure 3 The refrigeration chamber 511 and the cold storage chamber 512 can be connected through a connecting water channel 55, and a connecting pump 551 is connected to the connecting water channel 55. When the connecting pump 551 is turned off, the connecting water channel 55 is disconnected, and the water in the refrigeration chamber 511 that has not yet cooled down cannot enter the cold storage chamber 512. When the connecting pump 551 is started, the connecting water channel 55 is connected, and the water in the refrigeration chamber 511 that has cooled down can enter the cold storage chamber 512 for storage under the pumping of the connecting pump 551.

[0054] See also Figure 2 In a specific embodiment of the present application, a cooling water circuit 7 may be further provided in the cooling water device 1, and the cooling water device 1 further includes a cooling valve 71, and the cooling valve 71 is connected to the cooling water circuit 7. One end of the cooling water circuit 7 is connected to the cold storage cavity 512, and the other end of the cooling water circuit 7 is connected to the first return water circuit 91.

[0055] In the structure provided in this specific embodiment, when the cold conduction valve 71 is connected, the cold conduction water circuit 7 can be used to conduct the cold water in the cold storage chamber 512 into the first return water circuit 91, and then the low-temperature cold water can be used to exchange heat and cool the heating part 42, thereby improving the heat dissipation effect of the heat exchange water circuit 6 on the heating part 42, and can further ensure the refrigeration efficiency of the refrigeration component 4.

[0056] When the cold water in the cold storage cavity 512 is stored for too long, a large number of microorganisms may breed in the cold water, resulting in the degradation of the water quality of this part of the water body, making it no longer suitable for users to take. Therefore, inputting this part of the water body into the first return water channel 91 through the cold water guiding channel 7 can not only improve the cooling effect on the heating part 42, but also use the high temperature of the heating part 42 to sterilize this part of the water body, and use the filter element 3 to filter this part of the water body again, so that the microorganisms in it can be killed by heating, and the filtered water body can be reused to prepare cold water, thus greatly improving the energy utilization rate and material utilization rate of the cold water making device 1.

[0057] For the situation where the water temperature in the heat exchange water channel 6 is too high, at this time, the heating part 42 cannot be effectively cooled, which will cause the temperature of the heating part 42 to be too high, resulting in a decrease in the refrigeration efficiency of the refrigeration component 4 and making it difficult to prepare cold water normally. At this time, inputting the water with a lower temperature in the cold storage cavity 512 into the first return water channel 91 can effectively cool the heating part 42, quickly solve the problems of overheating of the heating part 42 and low refrigeration efficiency of the refrigeration component 4, and effectively ensure the stability of the cold water making water channel.

[0058] As Figure 2 shown, in a specific embodiment of the present application, the cold water making device 1 may further include a first temperature detection component 95 and a controller 97. The first temperature detection component 95 is arranged in at least one of the heating part 42, the circulating water channel 61, and the heat exchange water cavity 62. The controller 97 is connected to the first temperature detection component 95 and the cold water guiding valve 71. Refer to Figure 2 , the first temperature detection component 95 may be specifically arranged at the bottom of the heat exchange water cavity 62. Because the density of the water body decreases as the temperature rises, the water body at the bottom of the heat exchange water cavity 62 usually has a lower temperature than the water body at the top of the heat exchange water cavity 62. When the first temperature detection component 95 is arranged at the bottom of the heat exchange water cavity 62, it can be used to detect the temperature of a part of the water body with a lower temperature in the heat exchange water cavity 62. When the temperature of this part of the water body is also too high, it means that there is no longer a suitable water body in the heat exchange water cavity 62 for heat exchange with the heating part 42.

[0059] In the structure provided in this specific embodiment, by providing a first temperature detector 95 in at least one of the heating part 42, the circulating water path 61, and the water heat exchange cavity 62, the temperature of the heating part 42 or the water body in the heat exchange water path 6 can be monitored by the first temperature detector 95. The temperature change monitored by the first temperature detector 95 can be fed back to the controller 97, enabling the controller 97 to control the opening and closing of the heat conduction valve 71 according to the measured temperature change of the first temperature detector 95. Thus, when the temperature of the heating part 42 or the water body in the heat exchange water path 6 is too high, the heat conduction valve 71 can be controlled to connect and input cold water into the first return water path 91, and the cold water is used to quickly cool down the heating part 42, quickly solving the problems of overheating of the heating part 42 and reduced refrigeration efficiency of the refrigeration part 4, and effectively ensuring the stability of the refrigeration water path.

[0060] Referring to Figures 1 - 3 , in a specific embodiment of the present application, the refrigeration water device 1 may further be provided with a first water outlet path 93. One end of the first water outlet path 93 is connected to the water outlet end 32 of the filter element 3, and the other end of the first water outlet path 93 is used to connect to the purified water outlet channel 102. In the structure provided in this specific embodiment, a first water outlet path 93 connecting the water outlet end 32 and the purified water outlet channel 102 is also provided. In addition to the input refrigeration water path 5 and the first return water path 91, the water body filtered by the filter element 3 can also be input into the purified water outlet channel 102 through the first water outlet path 93, so as to be supplied for users to use.

[0061] Optionally, as Figure 1 shown, a filtered water outlet valve 931 may be connected in the first water outlet path 93. The filtered water outlet valve 931 is used to control the opening and closing of the first water outlet path 93. When the filtered water outlet valve 931 is disconnected, the first water outlet path 93 is disconnected, and the water body output from the water outlet end 32 of the filter element 3 cannot enter the purified water outlet channel 102 through the first water outlet path 93.

[0062] Referring to Figure 1 , Figure 2 , Figure 3 , in a specific embodiment of the present application, the circulating water path 61 is thermally connected to the heating part 42. The circulating water path 61 includes a high-temperature end 612 and a low-temperature end 611, and the water body in the circulating water path 61 flows from the low-temperature end 611 to the high-temperature end 612. The high-temperature end 612 is connected to the top of the water heat exchange cavity 62, and the low-temperature end 611 is connected to the bottom of the water heat exchange cavity 62. The first return water path 91 is connected to the low-temperature end 611.

[0063] In the structure provided by this specific embodiment, the first return water channel 91 can be used to convey the water filtered by the filter element 3 to the low-temperature end 611 of the circulation channel 61, so that this part of the relatively low-temperature water can flow through the heating part 42 along the circulation channel 61, and after cooling the heating part 42, it flows into the heat exchange water cavity 62 through the high-temperature end 612 to await the next entry into the low-temperature end 611 of the circulation channel 61.

[0064] Optionally, the refrigerated water device 1 can also be provided with a second return water channel 92. One end of the second return water channel 92 is communicated with the water outlet end 32, and the other end of the second return water channel 92 is arranged at the bottom of the heat exchange water cavity 62 and is communicated with the heat exchange water cavity 62. The second return water channel 92 can be used to directly input the filtered water to the bottom of the heat exchange water cavity 62, so that it can enter the low-temperature end 611 communicating with the bottom of the heat exchange water cavity 62 for dissipating heat from the heating part 42. Through the cooperation of the first return water channel 91 and the second return water channel 92, the filtered water can be returned to the heat exchange water, and the relatively low-temperature returned water can be used for heat exchange with the heating part 42 as soon as possible before being heated by other relatively high-temperature water in the heat exchange water channel 6, thereby improving the heat dissipation efficiency of the refrigerated water device 1.

[0065] Optionally, referring to Figure 1 , a second return water valve 921 can be connected in the second return water channel 92. The second return water valve 921 is used to control the on-off of the second return water channel 92. When the second return water valve 921 is disconnected, the water at the water outlet end 32 cannot directly enter the bottom of the heat exchange water cavity 62 through the second return water channel 92.

[0066] Referring to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 , Figure 4 is a schematic assembly structure diagram of the cold water tank, heat exchanger, and heat exchange water tank provided by this application. Figure 5 is Figure 4 the sectional structure schematic diagram of the section shown by A-A in Figure 6 is Figure 4Schematic cross-sectional structure view of the cross-section shown as B-B. Specifically, the cold water cavity 51 can be formed within the cold water tank 51a, the water path for heat exchange with the heating part 42 can be arranged within the heat exchanger 104, and the heat exchange water cavity 62 can be formed within the heat exchange water tank 62a. The refrigerating member 4 is connected to the cold water tank 51a and the heat exchanger 104, such that the refrigerating part 41 is arranged facing the inside of the cold water cavity 51, and the heating part 42 is thermally connected to the heat exchanger 104. A part of the circulating water path 61 is arranged within the heat exchanger 104 to be thermally connected to the heating part 42, and the remaining part of the circulating water path 61 is formed within the pipeline, and one end of the pipeline is connected to the heat exchanger 104, and the other end of the pipeline is connected to the heat exchange water tank 62a, such that the circulating water path 61 within the pipeline can communicate with the heat exchange water cavity 62 within the heat exchange water tank 62a.

[0067] Since the water body with a higher temperature has a smaller density, the water body within the heat exchange water cavity 62 shows a distribution trend where the temperature gradually increases from bottom to top. As Figure 6 shown, in the vertical direction, the pipeline provided with the high-temperature end 612 is connected to the upper end of the heat exchange water tank 62a, such that the high-temperature heat exchange water output from the high-temperature end 612 can enter the upper layer of the heat exchange water cavity 62, and the pipeline provided with the low-temperature end 611 is connected to the lower end of the heat exchange water tank 62a, such that the circulating water path 61 can obtain low-temperature heat exchange water from the lower layer of the heat exchange water cavity 62 through the low-temperature end 611, which conforms to the temperature distribution of the water body within the heat exchange water cavity 62.

[0068] As Figures 1 - 3 shown, the water inlet pipeline 2 can be divided into two parts. The first part of the water inlet pipeline 2 is used to connect the water source and the circulating water path 61 adjacent to the low-temperature end 611, and the second part of the water inlet pipeline 2 connects the water inlet end 31 and the water outlet of the heat exchanger 104. The circulation valve 614 is connected between the circulating water path 61 and the heat exchange water cavity 62. At this time, even if the circulation valve 614 is disconnected, the water body in the water inlet pipeline 2 input from the water source can borrow a part of the circulating water path 61 to flow through the heating part 42, and then enter the filter element 3 from the water inlet end 31 after heat exchange with the heating part 42.

[0069] As Figures 1 - 3 shown, in a specific embodiment of the present application, the refrigerated water device 1 can further be provided with a waste water discharge path 8, and the refrigerated water device 1 can further include a waste water valve 81. The waste water valve 81 is connected within the waste water discharge path 8, and one end of the waste water discharge path 8 communicates with the circulating water path 61 and / or the heat exchange water cavity 62.

[0070] In the structure provided in this specific embodiment, when the wastewater valve 81 is opened, the water in the heat exchange water path 6 can be discharged through the wastewater discharge path 8. Furthermore, when the temperature of the heat exchange water is too high and the cooling efficiency of the heating part 42 decreases, the high-temperature heat exchange water in the heat exchange water path 6 can be discharged through the wastewater discharge path 8, and then low-temperature water is replenished into the heat exchange water path 6 through the water inlet passage or the first return water path 91, so as to reduce the temperature of the water in the heat exchange water path 6 and achieve the purpose of improving the cooling effect of the heating part 42.

[0071] Refer to Figure 3 , in a specific embodiment of the present application, the refrigerated water device 1 may further include a water inlet valve 21, a second temperature detection member 96 and a controller 97. The water inlet valve 21 is connected to the water inlet pipe 2, and the second temperature detection member 96 is disposed in at least one of the heating part 42, the circulating water path 61, and the heat exchange water cavity 62. The controller 97 is connected to the second temperature detection member 96, the water inlet valve 21, and the wastewater valve 81. As Figure 3 shown, the second temperature detection member 96 may be disposed at the bottom of the heat exchange water cavity 62.

[0072] In the structure provided in this specific embodiment, by disposing the second temperature detection member 96 in at least one of the heating part 42, the circulating water path 61, and the heat exchange water cavity 62, the temperature of the heating part 42 or the water in the heat exchange water path 6 can be monitored by the second temperature detection member 96. The temperature change monitored by the second temperature detection member 96 can be fed back to the controller 97, so that the controller 97 can control the on-off of the water inlet valve 21 and the wastewater valve 81 according to the temperature change measured by the second temperature detection member 96. Thus, when the temperature of the heating part 42 or the water in the heat exchange water path 6 is too high, the water inlet valve 21 can be controlled to communicate to input water with a lower temperature into the heat exchange water path 6, and the wastewater valve 81 can be controlled to communicate to discharge the water with a higher temperature in the heat exchange water path 6, and cold water is used to quickly cool the heating part 42, and the temperature of the water in the heat exchange water path 6 can be quickly reduced, so as to solve the problems of overheating of the heating part 42 and reduced refrigeration efficiency of the refrigeration member 4, and effectively ensure the stability of the refrigerated water water path.

[0073] Refer to Figure 3 , in a specific embodiment of the present application, the refrigerated water device 1 may further be provided with a second water outlet path 94. One end of the second water outlet path 94 communicates with the circulating water path 61 and / or the heat exchange water cavity 62, and the other end is used to communicate with the hot water outlet channel 103.

[0074] In the structure provided in this specific embodiment, the heat exchange water path 6 and the hot water outlet channel 103 can be communicated by using the second water outlet path 94, so that the water with a higher temperature that has exchanged heat with the heating part 42 in the heat exchange water path 6 can be output through the hot water outlet channel 103, so as to provide water with a higher temperature to the user.

[0075] Optionally, as Figure 3 shown, a hot water outlet valve 941 may be connected to the second water outlet passage 94. The hot water outlet valve 941 is used to control the on / off of the second water outlet passage 94. When the hot water outlet valve 941 is turned off, the water in the circulating water passage 61 or the hot water replacement cavity 62 cannot enter the hot water outlet passage 103 through the second water outlet passage 94.
