[0002] The refrigeration water equipment can prepare water bodies with a temperature lower than normal temperature, and can meet the use demand of users for low-temperature water bodies.

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

[0032] The refrigerated water device can prepare a water body with a temperature lower than normal temperature, which can meet the user's use demand for low-temperature water body, so the refrigerated water device is more and more common in both commercial and household scenarios.

[0033] In the refrigerated water device, the refrigeration part will also have a heating phenomenon while refrigerating the water body, which will affect the refrigeration efficiency of the refrigeration part. In order to ensure the efficiency of the refrigerated water, the heat dissipation structure is usually set for the heating part of the refrigeration part, and the heat dissipation structure is used to dissipate heat from the refrigeration part to improve the working efficiency of the refrigeration part and ensure that the refrigerated water device can effectively provide cold water to the user. However, the heat taken away by the heat dissipation structure cannot be effectively utilized, but is directly dissipated or discharged, greatly reducing the energy utilization rate of the refrigerated water device.

[0034] In order 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.

[0035] Reference Figure 1 , Figure 1Fig. 1 is a schematic diagram of a water path structure of a first embodiment of the refrigerated water device provided in the present application. The specific embodiments of the present application can provide a refrigerated water device 1 that can be used to prepare water bodies with a temperature lower than room temperature.

[0036] The refrigerated water device 1 can include a water inlet pipe 2, a filter element 3, a refrigeration component 4, a refrigerated water path 5, and a heat exchange water path 6. The filter element 3 can be provided with a water inlet end 31 and a water outlet end 32. The refrigeration component 4 is provided with a refrigeration part 41 and a heat generation part 42. The refrigerated water path 5 is at least connected to the water outlet end 32, and the refrigerated water path 5 is in thermal contact with the refrigeration part 41. The heat exchange water path 6 is connected to the water inlet pipe 2 or the heat exchange water path 6 is connected to the water outlet end 32 and the water inlet pipe 2. The heat exchange water path 6 can include a circulating water path 61 and / or a heat exchange water cavity 62, and at least one of the circulating water path 61 and the heat exchange water cavity 62 is in thermal contact with the heat generation part 42. The water inlet pipe 2 passes through the heat generation part 42 and is connected to the water inlet end 31. The water outlet end 32 and the water inlet pipe 2 are connected by a first return water path 91 for allowing the water outlet from the water outlet end 32 to flow through the heat generation part 42.

[0037] In the structure provided in the specific embodiments, by providing the water inlet pipe 2 and the first return water path 91, the heat exchange water flowing through the heat generation part 42 can be input into the water inlet end 31 of the filter element 3 through the water inlet pipe 2, and the water filtered by the filter element 3 and output from the water outlet end 32 can flow through the heat generation part 42 by the first return water path 91. In addition, the refrigeration component 4 can also use the water output from the water outlet end 32 of the filter element 3 to make the water body after the heat exchange process through the heat exchange water path 6 and / or the water inlet pipe 2 flow through the heat generation part 42 for heat exchange, so that the water body can be used to prepare cold water or be used again for heat exchange of the heat generation part 42. The heat exchange water produced in the heat exchange process can be effectively recycled, which can reduce the waste of heat exchange water while maintaining the refrigeration efficiency of the refrigeration component 4, and improve the material utilization rate of the refrigerated water device 1.

[0038] In addition, the temperature of the heat exchange water increases after flowing through the heat generation part 42. When the heat exchange water with a higher temperature is filtered by the filter element 3, the heat can be conducted 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 is always circulated in the heat exchange water path 6 for heat exchange, the heat exchange water output from the water outlet end 32 after cooling can be used again for heat exchange, which can effectively improve the cooling efficiency of the heat generation part 42. In addition, the viscosity of the water body decreases with the increase of temperature, and the molecular motion is more intense. Therefore, for some types of filter elements 3, appropriately increasing the temperature can increase the filtering speed of the filter element 3. The heat taken away from the heat generation part 42 by the heat exchange water can be used to increase the filtering speed of the filter element 3, thereby improving the energy utilization rate of the refrigerated water device 1.

[0039] Specifically, the filter element 3 can include a reverse osmosis filter element, an ultrafiltration filter element, and an ion exchange resin filter element. As the temperature increases, the viscosity of water decreases, the molecular diffusion accelerates, the water permeability of the reverse osmosis membrane in the reverse osmosis filter element increases, and the speed of water passing through the ultrafiltration membrane of the ultrafiltration filter element increases, which can increase the output speed of the filtered water from the reverse osmosis filter element and the ultrafiltration filter element. 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.

[0040] Referring to Figure 1 , the water inlet pipeline 2 can be connected with a water inlet pump 22, a water inlet valve 21, and a filtered water inlet valve 23. The water inlet pump 22 and the water inlet valve 21 are used to pump the water in the water inlet pipeline 2 to flow to the water inlet end 31 of the filter element 3 through the heating portion 42. The filtered water inlet valve 23 is used to control whether the water inlet pipeline 2 is in communication 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.

[0041] When the type of the filter element 3 is a reverse osmosis filter element, the filter element 3 can 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 can 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 water flowing through the water outlet end 32 has the lowest impurity content, the water flowing through the water inlet end 31 has the second lowest impurity content, 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 can be used to discharge the concentrated water from the refrigerated water device 1, so as to avoid the concentrated water remaining in the filter element 3 and affecting the hygiene of the filter element 3.

[0042] As shown in Figure 1 , the circulating water pipeline 61 can be connected with a circulating pump 613 and a circulating valve 614. The circulating pump 613 is used to promote the circulation of the water between the circulating water pipeline 61 and the heat exchange water cavity 62. The circulating valve 614 is used to control the opening and closing of the circulating water pipeline 61. When the circulating valve 614 is disconnected, the water in the circulating water pipeline 61 and the heat exchange water cavity 62 cannot continue to circulate, and the water in the water inlet pipeline 2 cannot re-enter the heat exchange water pipeline 6. However, the water in the water inlet pipeline 2 can still flow to the water inlet end 31 through the heating portion 42, so as to realize heat exchange with the heating portion 42.

[0043] Optionally, the first backwater pipeline 91 can be connected with a first backwater valve 911. The first backwater valve 911 is used to control the opening and closing of the first backwater pipeline 91. When the first backwater valve 911 is disconnected, the water output from the water outlet end 32 cannot flow through the heating portion 42 again through the first backwater pipeline 91.

[0044] In a specific embodiment of the present application, referring to Figure 7 ,Figure 7 This is a schematic diagram of the water circuit structure of the fourth embodiment of the chilled water equipment provided in this application. The inlet pipe 2 may specifically include a sterilization inlet pipe 24 and a sterilization outlet pipe 25. The first end of the sterilization inlet pipe 24 is connected to the hot water exchange pipe 6, and the second end of the sterilization inlet pipe 24 is connected to the chilled water pipe 5. One end of the sterilization outlet pipe 25 is connected to the chilled water pipe 5, and the other end of the sterilization outlet pipe 25 is connected to the inlet end 31 and / or the hot water exchange pipe 6.

[0045] Among them, the hot water exchange circuit 6 can be connected to the water outlet 32, so that the water used for hot water exchange in the hot water exchange circuit 6 is filtered by the filter element 3, thus having better water quality.

[0046] Optionally, the water inlet pipe 2 may include a purified water inlet pipe 26, one end of which is connected to the hot water exchange pipe 6, and the other end of which is used to connect to the water outlet 32 ​​and / or an external purified water source, so that water filtered by the filter element 3 or externally prepared purified water can also be used as hot water for hot water exchange.

[0047] In the structure provided in this specific embodiment, the hot water with good water quality is introduced into the cooling water circuit 5 through the sterilization inlet water circuit 24, which can flush the cooling water circuit 5. When the hot water has a high temperature, high-temperature sterilization can also be carried out at the same time as flushing, which can effectively clean the cooling water circuit 5, remove microorganisms and accumulated impurities that grow in the cooling water circuit 5 during use, effectively reuse the hot water, and improve the water quality of the cold water produced by the cooling water circuit 5.

[0048] The water used to rinse the cooling water circuit 5 can be input into the inlet 31 through the sterilization outlet 25 and filtered by the filter element 3, so that the hot water can be recycled after filtration, and the residual heat of the hot water can also be used to heat the filter element 3, which can improve the energy utilization rate and material utilization rate of the cooling water equipment 1.

[0049] like Figure 1 As shown in a specific embodiment of this application, the cooling water circuit 5 may include a cold water cavity 51, a cooling water inlet circuit 52, and a cooling water outlet circuit 53. The cooling water inlet circuit 52 connects the water outlet 32 ​​and the cold water cavity 51, and the cooling water outlet circuit 53 connects the cold water cavity 51 and the cold water outlet channel 101. The cold water cavity 51 is thermally connected to the cooling unit 41.

[0050] In the structure provided in the 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, so that 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 part 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.

[0051] Optionally, referring to Figure 1 , the refrigeration water inlet path 52 can be connected with a refrigeration water inlet valve 521, which can control the opening and closing of the refrigeration water inlet path 52. When the refrigeration water inlet valve 521 is closed, the water output from the water outlet end 32 cannot enter the cold water cavity 51. The refrigeration water outlet path 53 can be connected with a cold water pump 531 and a cold water valve 532. 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. The cold water valve 532 is used to control the opening and closing 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.

[0052] As Figure 1 shown, the cold water outlet channel 101 can also be connected with a cold water outlet valve 101a, which is used to control the opening and closing 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 for the user. The cold water cavity 51 can be connected with an exhaust path 54, which is connected to the top of the cold water cavity 51 and can be used to exhaust the bubbles in the cold water cavity 51.

[0053] Further, the refrigeration water outlet path 53 can also be connected with a filter waste water 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 filter waste water path 331. When the water in the cold water cavity 51 is stored for too long, microorganisms may be bred therein, which is no longer suitable for being taken by the user. Therefore, this part can be input into the filter waste water path 331 to be discharged, so as to avoid polluting the cold water outlet channel 101.

[0054] Specifically, in Figure 7In the shown embodiment, the sterilization water inlet channel 24 can be connected to the refrigeration water inlet channel 52 of the refrigeration water channel 5, and the sterilization water outlet channel 25 can be connected to the refrigeration water outlet channel 53 of the refrigeration water channel 5. The heat exchange water flows through the cold water cavity 51 after entering the refrigeration water inlet channel 52, and then enters the sterilization water outlet channel 25 through the refrigeration water outlet channel 53. The water in the sterilization water outlet channel 25 can enter the water inlet end 31 and be filtered by the filter element 3 again. The cold water cavity 51 for preparing cold water can be fully washed and sterilized, and the heat exchange water used for sterilization can be filtered and then used for other purposes.

[0055] 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. Referring to Figure 2 、 Figure 3 , Figure 2 is a water channel structure schematic diagram of a second embodiment of the refrigeration water equipment provided by the present application. Figure 3 is a water channel structure schematic diagram of a 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 in an up-down manner, and in Figure 3 , the refrigeration cavity 511 and the cold storage cavity 512 are arranged in a left-right manner.

[0056] The refrigeration cavity 511 is used for directly heat-conducting connection with the refrigeration part 41 to prepare cold water, and the cold storage cavity 512 is used for storing cold water. The refrigeration cavity 511 can be selectively connected to the cold storage cavity 512. The refrigeration cavity 511 is heat-conducting connected to the refrigeration part 41, the refrigeration water inlet channel 52 is connected to the refrigeration cavity 511, and the refrigeration water outlet channel 53 is connected to the cold storage cavity 512.

[0057] In the structure provided in the specific embodiment, the filtered water output from the water outlet end 32 can be input into the refrigeration cavity 511 for cooling. The selective connection relationship between the refrigeration cavity 511 and the cold storage cavity 512 is used to make the water in the cold storage cavity 512 not directly contact with the higher temperature water input from the refrigeration water inlet channel 52. After the water in the refrigeration cavity 511 is cooled to the right temperature, the refrigeration cavity 511 and the cold storage cavity 512 are connected to supplement the water in the cold storage cavity 512. The water in the cold storage cavity 512 can always be kept at a lower temperature, so that the temperature of the water output from the cold storage cavity 512 through the refrigeration water outlet channel 53 is relatively stable and does not exceed the user's demand.

[0058] Especially for the water output by the water outlet 32 is used for heat exchange, even if the water after heat exchange with the heating part 42 is filtered by the filter element 3, the temperature is slightly reduced, but compared with the cold water in the cold storage cavity 512, the temperature is still higher. Direct contact of such water with cold water will cause the temperature of the cold water to change significantly. If the transition between the refrigeration cavity 511 and the cold storage cavity 512 is not realized by the refrigeration cavity 511, the temperature of the cold water in the cold water outlet channel 101 will increase suddenly, which will seriously affect the usability of the refrigeration water equipment 1.

[0059] At the same time, after the refrigeration cavity 511 and the cold storage cavity 512 are separated, only the water in the refrigeration cavity 511 is directly heat-exchanged with the refrigeration part 41, and the total volume of the directly heat-exchanged water is reduced, so the cooling speed of the water is also faster. While the cold water in the cold storage cavity 512 is output to the cold water outlet channel 101, the refrigeration cavity 511 can quickly prepare and supplement the cold water into the cold storage cavity 512, and the preparation and use of the cold water do not interfere with each other.

[0060] Specifically, referring to Figure 2 、 Figure 3 , the refrigeration cavity 511 and the cold storage cavity 512 can be communicated through the communication water channel 55, and the communication pump 551 is connected in the communication water channel 55. When the communication pump 551 is closed, the communication water channel 55 is disconnected, and the water in the refrigeration cavity 511 that has not been cooled to the right position cannot enter the cold storage cavity 512. When the communication pump 551 is started, the communication water channel 55 is communicated, and the water in the refrigeration cavity 511 that has been cooled to the right position can enter the cold storage cavity 512 for storage under the pumping of the communication pump 551.

[0061] Referring to Figure 2 , in a specific embodiment of the present application, the refrigeration water equipment 1 can also be provided with a cold water guide channel 7, and the refrigeration water equipment 1 further comprises a cold water guide valve 71 connected in the cold water guide channel 7. One end of the cold water guide channel 7 communicates with the cold storage cavity 512, and the other end of the cold water guide channel 7 communicates with the first return water channel 91.

[0062] In the structure provided in the specific embodiment, when the cold water guide valve 71 is communicated, the cold water guide channel 7 can be used to guide the cold water in the cold storage cavity 512 into the first return water channel 91, and then the low-temperature cold water can be used to heat-exchange and cool the heating part 42, thereby improving the heat dissipation effect of the heat-exchange water channel 6 on the heating part 42, and further ensuring the refrigeration efficiency of the refrigeration part 4.

[0063] 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, causing the water quality of this part of water to decrease and no longer suitable for being taken by the user. Therefore, inputting this part of water into the first return water path 91 through the cold water guide path 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 water, and use the filter element 3 to filter this part of water again, so that the microorganisms in it can be killed by rising temperature, and the filtered water can be used to prepare cold water again, thereby greatly improving the energy utilization rate and material utilization rate of the cold water preparation equipment 1.

[0064] For the case that the temperature of the water in the heat exchange water path 6 is too high, the heating part 42 cannot be effectively cooled at this time, which will cause the temperature of the heating part 42 to be too high, and the refrigeration efficiency of the refrigeration part 4 to decrease and be difficult to normally prepare cold water. At this time, inputting the water with lower temperature in the cold storage cavity 512 into the first return water path 91 can effectively cool the heating part 42, quickly solve the problem of overheating of the heating part 42 and low refrigeration efficiency of the refrigeration part 4, and effectively guarantee the stability of the cold water path.

[0065] As shown in the specific embodiment of the present application, Figure 2 The cold water preparation equipment 1 can further include a first temperature detection part 95 and a controller 97, the first temperature detection part 95 is arranged in at least one of the heating part 42, the circulating water path 61 and the heat exchange water cavity 62, and the controller 97 is connected with the first temperature detection part 95 and the cold water guide valve 71. Referring to Figure 2 , the first temperature detection part 95 can be arranged at the bottom of the heat exchange water cavity 62. Because the density of water decreases with the increase of temperature, the water at the bottom of the heat exchange water cavity 62 is usually lower in temperature than the water at the top of the heat exchange water cavity 62. When the first temperature detection part 95 is arranged at the bottom of the heat exchange water cavity 62, it can be used to detect the temperature of the part of water with lower temperature in the heat exchange water cavity 62. When the temperature of this part of water is also too high, it indicates that there is no longer water suitable for heat exchange with the heating part 42 in the heat exchange water cavity 62.

[0066] In the structure provided in the specific embodiment, by arranging the first temperature detecting member 95 in at least one of the heating portion 42, the circulating water path 61 and the heat exchange water cavity 62, the temperature of the heating portion 42 or the water in the heat exchange water path 6 can be monitored by the first temperature detecting member 95, and the temperature change monitored by the first temperature detecting member 95 can be fed back to the controller 97, so that the controller 97 can control the on-off of the cooling valve 71 according to the temperature change measured by the first temperature detecting member 95. Thus, when the temperature of the heating portion 42 or the water in the heat exchange water path 6 is too high, the cooling valve 71 is controlled to connect to the first return water path 91 to input cold water, and the heating portion 42 is rapidly cooled by the cold water, so that the problem of overheating of the heating portion 42 and the reduced refrigeration efficiency of the refrigeration member 4 can be quickly solved, and the stability of the refrigeration water path can be effectively ensured.

[0067] Referring to Figures 1-3 In the specific embodiment, the refrigeration water device 1 can further be provided with a first water outlet path 93, one end of the first water outlet path 93 being connected to the water outlet end 32 of the filter element 3, and the other end of the first water outlet path 93 being used to connect to the clean water outlet channel 102. In the structure provided in the specific embodiment, the first water outlet path 93 connecting the water outlet end 32 and the clean water outlet channel 102 is further arranged, and in addition to the input refrigeration water path 5 and the first return water path 91, the first water outlet path 93 can be used to input the water filtered by the filter element 3 into the clean water outlet channel 102, so as to supply the user.

[0068] Optionally, as Figure 1 shown, the first water outlet path 93 can be connected with a filtered water outlet valve 931, and the filtered water outlet valve 931 is used to control the on-off 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 output from the water outlet end 32 of the filter element 3 cannot enter the clean water outlet channel 102 through the first water outlet path 93.

[0069] Referring to Figure 1 , Figure 2 , Figure 3 In the specific embodiment, the circulating water path 61 is thermally connected to the heating portion 42, the circulating water path 61 includes a high-temperature end 612 and a low-temperature end 611, and the water 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 heat exchange water cavity 62, and the low-temperature end 611 is connected to the bottom of the heat exchange water cavity 62. The first return water path 91 is connected to the low-temperature end 611.

[0070] In the structure provided in the specific embodiment, the water filtered by the filter element 3 can be delivered to the low-temperature end 611 of the circulating water path 61 by the first water return path 91, so that the water with lower temperature can flow through the heat generating part 42 along the circulating water path 61 and then flow into the heat exchange water cavity 62 through the high-temperature end 612 after cooling the heat generating part 42 for the next time into the low-temperature end 611 of the circulating water path 61.

[0071] Optionally, the refrigerated water equipment 1 can also be provided with a second water return path 92, one end of the second water return path 92 being communicated with the water outlet end 32, and the other end of the second water return path 92 being arranged at the bottom of the heat exchange water cavity 62 and being communicated with the heat exchange water cavity 62. The filtered water can be directly input into the bottom of the heat exchange water cavity 62 by the second water return path 92, so as to enter the low-temperature end 611 communicated with the bottom of the heat exchange water cavity 62 for cooling the heat generating part 42. By cooperation of the first water return path 91 and the second water return path 92, the filtered water can be returned to the heat exchange water, and the water with lower temperature returned can be heated by other water with higher temperature in the heat exchange water path 6 as soon as possible for heat exchange with the heat generating part 42, so as to improve the heat dissipation efficiency of the refrigerated water equipment 1.

[0072] Optionally, referring to Figure 1 , the second water return path 92 can be connected with a second water return valve 921, and the second water return valve 921 is used for controlling the opening and closing of the second water return path 92. When the second water return valve 921 is disconnected, the water of the water outlet end 32 cannot directly enter the bottom of the heat exchange water cavity 62 through the second water return path 92.

[0073] Referring to Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 , Figure 4 is an assembly structure schematic view of the cold water tank, the heat exchanger and the heat exchange water tank provided in the application. Figure 5 is Figure 4 is a sectional structure schematic view of the section A-A shown in Figure 6 is Figure 4The diagram shows a cross-sectional view of section BB. Specifically, the cold water cavity 51 can be formed inside the cold water tank 51a, the water passage for heat exchange with the heating element 42 can be located inside the heat exchanger 104, and the hot water cavity 62 can be formed inside the hot water tank 62a. The refrigeration component 4 is connected to the cold water tank 51a and the heat exchanger 104, with the refrigeration element 41 facing into the cold water cavity 51, and the heating element 42 thermally connected to the heat exchanger 104. Part of the circulating water passage 61 is located inside the heat exchanger 104 for thermal connection with the heating element 42, and the remaining circulating water passage 61 is formed in a pipeline, with one end of the pipeline connected to the heat exchanger 104 and the other end connected to the hot water tank 62a, so that the circulating water passage 61 in the pipeline can connect to the hot water cavity 62 inside the hot water tank 62a.

[0074] Because water with higher temperatures has lower density, the water in the hot water exchange chamber 62 exhibits a temperature distribution trend of gradually increasing from bottom to top. For example... Figure 6 As shown, in the vertical direction, a pipe with a high-temperature end 612 is connected to the upper end of the hot water exchange tank 62a, so that the high-temperature hot water output from the high-temperature end 612 can enter the upper layer of the hot water exchange cavity 62. A pipe with a low-temperature end 611 is connected to the lower end of the hot water exchange tank 62a, so that the circulating water circuit 61 can obtain low-temperature hot water from the lower layer of the hot water exchange cavity 62 through the low-temperature end 611, which is in line with the temperature distribution of the water in the hot water exchange cavity 62.

[0075] like Figures 1-3 As shown, the water inlet pipe 2 can be divided into two parts. The first part of the water inlet pipe 2 is used to connect the water source and the circulating water circuit 61 adjacent to the low temperature end 611. The second part of the water inlet pipe 2 connects the water inlet end 31 and the outlet of the heat exchanger 104. The circulation valve 614 is connected between the circulating water circuit 61 and the heat exchange chamber 62. At this time, even if the circulation valve 614 is disconnected, the water input from the water source into the water inlet pipe 2 can use part of the circulating water circuit 61 to flow through the heating element 42, and then exchange heat with the heating element 42 before entering the filter element 3 from the water inlet end 31.

[0076] like Figures 1-3 As shown in a specific embodiment of this application, the chilled water equipment 1 may also be provided with a wastewater discharge path 8, and the chilled water equipment 1 may also include a wastewater valve 81. The wastewater valve 81 is connected to the wastewater discharge path 8, and one end of the wastewater discharge path 8 is connected to the circulating water path 61 and / or the hot water exchange chamber 62.

[0077] In the structure provided in the specific embodiment, when the waste water valve 81 is opened, the water in the heat exchange water path 6 can be discharged through the waste water path 8, and when the temperature of the heat exchange water is too high and the cooling efficiency of the heating part 42 is reduced, the high-temperature heat exchange water in the heat exchange water path 6 can be discharged through the waste water path 8, and low-temperature water can be supplemented 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.

[0078] Referring to Figure 3 In a specific embodiment of the present application, the refrigerated water device 1 can further include a water inlet valve 21 connected to the water inlet passage 2, a second temperature detection member 96 arranged in at least one of the heating part 42, the circulating water path 61, and the heat exchange water cavity 62, and a controller 97 connected to the second temperature detection member 96, the water inlet valve 21, and the waste water valve 81. As shown in Figure 3 The second temperature detection member 96 can be arranged at the bottom of the heat exchange water cavity 62.

[0079] In the structure provided in the specific embodiment, by arranging 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 opening and closing of the water inlet valve 21 and the waste water valve 81 according to the temperature change detected by the second temperature detection member 96. Therefore, 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 connect to input low-temperature water into the heat exchange water path 6, and the waste water valve 81 can be controlled to connect to discharge high-temperature water in the heat exchange water path 6, so as to quickly cool the heating part 42 by using cold water, quickly reduce the temperature of the water in the heat exchange water path 6, and solve the problem of overheating of the heating part 42 and the reduced refrigeration efficiency of the refrigeration member 4, thereby effectively ensuring the stability of the refrigerated water path.

[0080] Referring to Figure 3 In a specific embodiment of the present application, the refrigerated water device 1 can further include a second water outlet path 94, one end of the second water outlet path 94 being connected to the circulating water path 61 and / or the heat exchange water cavity 62, and the other end being used to connect to a hot water outlet passage 103.

[0081] In the structure provided in the specific embodiment, the second water outlet path 94 can be used to connect the heat exchange water path 6 and the hot water outlet passage 103, so that the water in the heat exchange water path 6 which has exchanged heat with the heating part 42 and has a high temperature can be output through the hot water outlet passage 103, thereby providing high-temperature water to the user.

[0082] Optionally, as shown in Figure 3 Figure 3 The hot water outlet valve 941 can be connected to the second water outlet path 94, and is used to control the opening and closing of the second water outlet path 94. When the hot water outlet valve 941 is closed, the water in the circulating water path 61 or the heat exchange water cavity 62 cannot enter the hot water outlet path 103 through the second water outlet path 94.
