[0044] like Figure 1 As shown in the figure, a refrigerated direct drinking water machine provided in this application embodiment includes a filter module 10, a hot water module 20, a refrigeration module 40, a wastewater module 50, and a refrigeration system 60.

[0045] The inlet of the hot water module 20 is connected to the outlet of the filter module 10. The inlet of the cooling module 40 is connected to the outlet of the hot water module 20. The wastewater module 50 includes a wastewater tank 51, the inlet of which is connected to the filter module 10 to collect wastewater generated during the filtration process. The cooling system 60 includes a compressor 61, a heat dissipation pipe 62, a condenser 63, and an evaporator. The compressor 61, heat dissipation pipe 62, condenser 63, and evaporator are sequentially connected in a circulating pipeline. The cooling system 60 contains refrigerant. The evaporator is located within the cooling module 40, and the heat dissipation pipe 62 is located within the wastewater tank 51.

[0046] In this application, the outlet of the filter module 10 and the inlet of the hot water module 20 can be directly connected, or indirectly connected through pipes or other intermediate structures, so that the water filtered by the filter module 10 can flow to the hot water module 20. Similarly, the inlet of the filter module 10 and the wastewater tank 51 can be directly connected, or indirectly connected through pipes or other intermediate structures, so that the wastewater from the filtration process of the filter module 10 can flow to the wastewater tank 51. Similarly, the outlet of the hot water module 20 and the inlet of the cooling module 40 can be directly connected, or indirectly connected through pipes or other intermediate structures, so that the water heated by the hot water module 20 can flow to the cooling module 40 for cooling, so that cold water, ice cubes, etc., are made from boiled water at high temperatures, which conforms to people's drinking habits and improves the user's drinking experience. Furthermore, to ensure the flow of water, the direction of water flow can be controlled by water valves and water pumps.

[0047] When the refrigeration system 60 cools the water in the refrigeration module 40, the compressor 61 compresses the refrigerant in the piping of the refrigeration system 60 into a high-temperature, high-pressure refrigerant, which is then discharged from the exhaust pipe of the compressor 61. The high-temperature, high-pressure refrigerant is then transported to the condenser 63 through the heat dissipation pipe 62, where it is cooled and condensed into a high-pressure liquid refrigerant. The high-pressure liquid refrigerant is then transported to the evaporator, where it absorbs heat and vaporizes, absorbing heat from the water in the refrigeration module 40, thus lowering the water temperature and achieving refrigeration. The gaseous refrigerant flowing out of the evaporator then flows back to the compressor 61, forming a refrigeration flow loop.

[0048] In the process of using the refrigeration direct drinking machine, the filter module 10 can filter the water, the filtered water flows to the hot water module 20 for heating, the hot water flows to the refrigeration module 40 for refrigeration, and the waste water in the filtering process flows to the waste water tank 51. In the process of refrigeration system 60 refrigerating the water in the refrigeration module 40, the high-temperature and high-pressure refrigerant flowing out of the compressor 61 will first enter the heat dissipation pipe 62 and exchange heat with the waste water in the waste water tank 51, so as to greatly reduce the temperature of the refrigerant entering the condenser 63, so that the condensing pressure of the condenser 63 is reduced, and the temperature of the refrigerant at the outlet of the condenser 63 is also reduced, the refrigeration capacity of the refrigerant entering the evaporator is improved, and the refrigeration power of the refrigeration system 60 is reduced, so that the energy consumption in the refrigeration process is reduced, and the purpose of saving energy is achieved.

[0049] As shown in Figure 2 In some embodiments, the water inlet of the filter module 10 is connected to the tap water inlet, so that when the water enters the refrigeration direct drinking machine, it can first enter the filter module 10 and be filtered for drinking. In this embodiment, the filter module 10 includes one or more of PP cotton, pre-activated carbon 12, RO membrane 15 and post-activated carbon 17, wherein the PP cotton can remove large particles in the water, the pre-activated carbon 12 can adsorb residual chlorine and odor in the water, the RO membrane 15 can perform deep filtration to remove small impurities in the water, and the post-activated carbon 17 can further adsorb odor in the water to improve the taste of the water. In this embodiment, the filter module 10 further includes a pressure pump 14 for driving the water flow. In this embodiment, the filter module 10 further includes a pressure barrel 16 connected to the RO membrane 15 for storing pure water filtered by the RO membrane 15 and providing stable water flow when needed. In this application, the water inlet of the waste water tank 51 is connected to the waste water outlet of the RO membrane 15, and after the water is deeply filtered by the RO membrane 15, the waste water in the filtering process can flow to the waste water tank 51 through the waste water outlet.

[0050] For example, the filter module 10 includes first PP cotton 11, pre-activated carbon 12, second PP cotton 13, pressure pump 14, RO membrane 15, pressure barrel 16 and post-activated carbon 17 connected in sequence from the water inlet to the water outlet. The RO membrane 15 is connected to the water inlet of the waste water tank 51, and after the water flows to the RO membrane 15 and is filtered by the RO membrane 15, the filtered water is pure water, enters the pressure barrel 16, and as the amount of pure water increases, the pressure in the pressure barrel 16 increases, and after the pure water is discharged, it is filtered again by the post-activated carbon 17 for drinking. The waste water in the filtering process flows to the waste water tank 51, for example, the water that fails to pass through the RO membrane 15 becomes waste water and is discharged to the waste water tank 51.

[0051] As shown in Figure 1 andFigure 3 As shown, in some embodiments, the wastewater module 50 further includes a wastewater inlet pipe 52, one end of which is connected to the top of the wastewater tank 51, and the other end is connected to the filter module 10. In this embodiment, the inlet of the wastewater tank 51 is located at the top of the wastewater tank 51, and the wastewater during the filtration process of the filter module 10 can flow from the top of the wastewater tank 51 into the wastewater tank 51 through the wastewater inlet pipe 52. Because the wastewater in the wastewater tank 51 has the characteristic of temperature stratification, after heat exchange with the wastewater through the heat dissipation pipe 62, the water temperature in the upper layer of the wastewater tank 51 is higher, and the water temperature in the lower layer is lower. In this embodiment, the wastewater enters directly from the top of the wastewater tank 51, which allows the lower-temperature wastewater to contact the upper layer of wastewater in the wastewater tank 51 first, thus achieving a uniform overall temperature of the wastewater and improving the heat exchange efficiency between the heat dissipation pipe 62 and the wastewater in the wastewater tank 51.

[0052] For example, the wastewater inlet pipe 52 is equipped with a wastewater inlet valve 521, which is used to control the flow rate of wastewater discharged during the filtration process of the filter module 10.

[0053] like Figure 3 As shown, in some embodiments, the wastewater module 50 further includes a wastewater outlet pipe 53, which is connected to the bottom of the wastewater tank 51. In this embodiment, the outlet of the wastewater tank 51 is located at the bottom of the wastewater tank 51, and the wastewater in the wastewater tank 51 can be discharged from the bottom through the wastewater outlet pipe 53, so that all the wastewater can be discharged, and the wastewater can be replaced at any time, thereby improving the heat exchange efficiency of the heat dissipation pipe 62. Alternatively, the wastewater can be used for other purposes, such as as non-potable water for domestic use.

[0054] For example, the wastewater outlet pipe 53 is equipped with a wastewater outlet valve 531 for opening and closing the wastewater outlet pipe 53 so that wastewater can be discharged at any time as needed.

[0055] like Figure 3 As shown, in some embodiments, the wastewater module 50 further includes a wastewater overflow pipe 54, which is connected to the wastewater tank 51. The wastewater overflow pipe 54 is connected to the overflow port of the wastewater tank 51. When the wastewater level in the wastewater tank 51 is high, excess wastewater can be discharged in time through the wastewater overflow pipe 54 to prevent the wastewater tank 51 from overflowing.

[0056] For example, the wastewater overflow pipe 54 is connected to the upper part of the wastewater tank 51 near the top so that excess wastewater can be discharged through the wastewater overflow pipe 54 before the wastewater tank 51 overflows.

[0057] like Figure 1As shown, in some embodiments, the inlet of the hot water module 20 and the outlet of the filter module 10 are connected by a pipe, and the pipe between the two is equipped with a hot water inlet valve 18 to control the flow rate of the water entering the hot water module 20.

[0058] like Figure 4 As shown, in some embodiments, the hot water module 20 includes a hot water tank 21 and a heater 22. The heater 22 is disposed inside the hot water tank 21. The hot water tank 21 has an inlet and an outlet for water to enter and exit. After water enters the hot water tank 21 from the inlet of the hot water module 20, the heater 22 can heat the water in the hot water tank 21, for example, it can heat it to 100°C to produce boiling water to meet drinking needs.

[0059] For example, heater 22 includes electric heating tube heater, quartz tube heater, ceramic heater, etc. This application is not limited, and any heater 22 that can heat water can be used in this application.

[0060] For example, the hot water module 20 also includes a hot water outlet pipe and a hot water outlet valve. The hot water outlet pipe is connected to the bottom of the hot water tank 21, and the hot water outlet valve is located on the hot water outlet pipe. The opening of the hot water outlet pipe can be adjusted by the hot water outlet valve, and the hot water outlet pipe can discharge boiling water for users to drink, thereby improving the user experience.

[0061] like Figure 4As shown, in some embodiments, the cooling direct drinking water machine further includes a warm water module 30. The warm water module 30 includes a heat exchange inner tube 32 and a heat exchange outer tube 31. One end of the heat exchange inner tube 32 is connected to the outlet of the hot water module 20, and the other end is connected to the inlet of the cooling module 40. One end of the heat exchange outer tube 31 is connected to the outlet of the filter module 10, and the other end is connected to the inlet of the hot water module 20. The heat exchange inner tube 32 is at least partially nested within the heat exchange outer tube 31. The heat exchange outer tube 31 is provided between the outlet of the filter module 10 and the inlet of the hot water module 20. The water filtered from the filter module 10 first passes through the heat exchange outer tube 31 before entering the hot water module 20. Therefore, the water temperature in the heat exchange outer tube 31 is relatively low. After the hot water module 20 heats the water, the resulting boiling water flows out from the outlet of the hot water module 20 and enters the heat exchange inner tube 32, where the water temperature is relatively high. In this embodiment, since the inner heat exchange pipe 32 is at least partially nested within the outer heat exchange pipe 31, it can exchange heat with the cooler water in the outer heat exchange pipe 31 when the water flows through it. This lowers the water temperature in the inner heat exchange pipe 32, resulting in warm water flowing out. In this embodiment, directly lowering the outlet water temperature of the hot water module 20 through the outer heat exchange pipe 31 increases the inlet water temperature, reducing energy consumption and improving heating efficiency. It also lowers the water temperature flowing into the cooling module 40, reducing energy consumption and improving cooling efficiency. Furthermore, lowering the outlet water temperature of the hot water module 20 eliminates the need for other cooling modules, significantly reducing costs. Of course, in other embodiments, the warm water module 30 can also be connected to a cooling module to actively cool boiling water.

[0062] For example, the warm water module 30 also includes a warm water outlet pipe and a warm water outlet valve. The warm water outlet pipe is connected to the tail end of the inner heat exchange pipe 32 after heat exchange with the outer heat exchange pipe 31. The warm water outlet valve is located on the warm water outlet pipe. The opening of the warm water outlet pipe can be adjusted by the warm water outlet valve, and the warm water outlet pipe can discharge warm water to provide users with warm water that has been cooled down from boiling water, thus improving the user experience.

[0063] like Figure 1As shown, in some embodiments, the refrigeration module 40 includes a cold water module 41 and an ice-making module 42. The evaporator includes a cold water evaporator 641 and an ice-making evaporator 642. The cold water evaporator 641 is disposed within the cold water module 41, and the ice-making evaporator 642 is disposed within the ice-making evaporator 642. The cold water evaporator 641 can cool the water flowing to the cold water module 41 to produce cold water, and the ice-making evaporator 642 can cool and condense the water flowing to the ice-making module 42 to produce ice. Thus, the refrigeration module 40 of this application can produce both cold water and ice, greatly improving the user's experience. Furthermore, the water in both the cold water module 41 and the ice-making module 42 is boiled water that has been heated. Therefore, both the cold water and the ice are made from boiled water, which better suits people's drinking habits and improves the user's drinking experience.

[0064] In other embodiments, the refrigeration module 40 may also include only one of the cold water module 41 and the ice-making module 42, without limitation.

[0065] like Figure 5 As shown, in some embodiments, the cold water module 41 includes a cold water tank 411 and a cold water temperature sensor 412. Both the chilled water evaporator 641 and the cold water temperature sensor 412 are located inside the cold water tank 411. After water enters the cold water tank 411 through the inlet, the refrigerant in the chilled water evaporator 641 can exchange heat with the water to absorb heat from the water, thereby cooling the water and achieving chilled water. The cold water temperature sensor 412 can detect the temperature inside the cold water tank 411, and the temperature feedback from the cold water tank 411 can be used to control the refrigeration system 60 to ensure that the water in the refrigeration tank meets the user's cold drinking water needs.

[0066] For example, the cold water module 41 also includes a cold water outlet pipe 413 and a cold water outlet valve 414. The cold water outlet pipe 413 is connected to the bottom of the cold water tank 411, and the cold water outlet valve 414 is located on the cold water outlet pipe 413. The opening of the cold water outlet pipe 413 can be adjusted by the cold water outlet valve 414, and cold water can be discharged from the cold water outlet pipe 413 for users to drink, thereby improving the user experience.

[0067] like Figure 6As shown, in some embodiments, the ice-making module 42 includes an ice-making chamber 421, an ice-making water tray 422, and an ice-making mold. The ice-making mold is disposed on an ice-making evaporator 642. Both the ice-making mold and the ice-making water tray 422 are disposed within the ice-making chamber 421, and the ice-making mold is at least partially placed in the water tank of the ice-making water tray 422. During the ice-making process, water can flow into the water tank of the ice-making water tray 422 and come into contact with the ice-making mold on the ice-making evaporator 642. The ice-making evaporator 642 absorbs heat from the water, thereby condensing the water onto the ice-making mold to produce ice blocks. The produced ice blocks then fall into the water tank of the ice-making water tray 422. Exemplarily, the ice-making mold has multiple cylindrical protrusions placed in the water tank of the ice-making water tray 422. After the water condenses on the cylindrical protrusions, bullet ice can be formed.

[0068] like Figure 6 As shown, in some embodiments, the ice-making module 42 further includes a flip motor 423, which is located in the ice-making chamber 421 and connected to the ice-making water tray 422. The flip motor 423 is used to drive the ice-making water tray 422 to flip. After the water in the ice-making water tray 422 is made into ice blocks, the flip motor 423 can drive the ice-making water tray 422 to flip, so that the ice blocks in the ice-making water tray 422 can be poured into the ice block storage chamber in the ice-making chamber 421 to store the ice blocks for convenient use by the user at any time.

[0069] For example, the upper compartment of the ice maker 421 can be opened to expose the ice storage compartment for easy access to ice. Alternatively, the ice storage compartment can be pulled out from the ice maker 421 for easy access to ice.

[0070] like Figure 6 As shown, in some embodiments, the ice-making module 42 further includes an empty ice detection probe 424 and a full ice detection probe 425, which are located inside the ice-making chamber 421. The empty ice detection probe 424 is located at the bottom of the ice storage chamber, and the full ice detection probe 425 is located at the top of the ice storage chamber. This allows the system to determine whether there is ice in the storage chamber or whether it is full, enabling control over whether to continue making ice based on feedback information. For example, the system can control whether the refrigeration system 60 cools through the ice-making evaporator 642, and whether the ice-making water tray 422 is filled with water, etc.

[0071] like Figure 6As shown, in some embodiments, the ice-making module 42 further includes a water storage tank 426, which is located at the bottom of the ice-making chamber 421 and below the ice storage chamber. The water storage tank 426 is used to store water for making ice. The inlet of the water storage tank 426 is used to receive water, and the outlet of the water storage tank 426 is connected to the ice-making water tray 422 via a pipe. An ice-making water pump 427 is installed on the pipe to pump the water in the water storage tank 426 into the water tank of the ice-making water tray 422 according to the control, thereby producing ice.

[0072] like Figure 1 As shown, in some embodiments, the outlet of the cold water module 41 is connected to the inlet of the ice-making module 42. In this way, the cold water module 41 can first cool the water to initially lower its temperature, and then supply the cold water to the ice-making module 42 for ice making. Thus, the ice-making evaporator 642 can quickly produce ice, thereby improving ice-making efficiency and reducing the energy consumption of the refrigeration system 60 during the ice-making process, further achieving energy conservation.

[0073] For example, the inlet of the cold water module 41 is connected to the warm water module 30 so that the water cooled by the warm water module 30 can flow to the cold water module 41 to achieve rapid cooling.

[0074] For example, the cold water outlet pipe 413 and the water storage tank 426 are connected by a pipe, and a water storage tank pump 43 is provided on the pipe. In this way, the water storage tank pump 43 can control the delivery of cold water in the cold water tank 411 to the water storage tank 426 for the ice making module 42 to make ice.

[0075] In some other embodiments, the cold water module 41 and the ice-making module 42 are supplied with water independently and do not interfere with each other. For example, the inlet of the cold water module 41 and the inlet of the ice-making module 42 are both connected to the warm water module 30. The cold water module 41 receives warm water from the warm water module 30 to make cold water, and the ice-making module 42 receives warm water from the warm water module 30 to make ice cubes.

[0076] like Figure 7 As shown, in some embodiments, the heat dissipation pipe 62 includes a heat dissipation coil, which is arranged by bending and coiling. When the heat dissipation pipe 62 is placed in the wastewater tank 51, it can fully contact the wastewater in the wastewater tank 51, so that the refrigerant in the heat dissipation pipe 62 can have sufficient heat exchange through the wastewater, thereby greatly reducing the condensing pressure of the condenser 63 and greatly reducing the temperature of the refrigerant at the outlet of the condenser 63. Therefore, the cooling capacity is improved and the cooling power is reduced, thus achieving the purpose of saving energy.

[0077] like Figure 7As shown, in some embodiments, the refrigeration system 60 further includes a defrost pipe 69, one end of which is connected to the ice-making evaporator 642, and the other end is connected between the outlet of the compressor 61 and the inlet of the condenser 63. When frost or ice forms on the ice-making evaporator 642, it affects the ice-making efficiency of the ice-making module 42 and increases ice-making energy consumption. In this embodiment, the defrost pipe 69 allows the higher-temperature refrigerant discharged from the compressor 61 to be delivered to the ice-making evaporator 642. Thus, the higher-temperature refrigerant melts the frost or ice on the ice-making evaporator 642, ensuring the ice-making efficiency of the ice-making module 42.

[0078] For example, one end of the defrost pipe 69 is connected between the heat dissipation pipe 62 and the condenser 63 via a T-connector, and the defrost pipe 69 is equipped with a defrost valve 691. When defrosting is required, the defrost valve 691 can be opened so that the refrigerant that has undergone preliminary heat dissipation through the heat dissipation pipe 62 can flow to the ice-making evaporator 642 to achieve the defrosting effect.

[0079] like Figure 7 As shown, in some embodiments, the refrigeration system 60 further includes a dryer filter 65, which is disposed between the outlet of the condenser 63 and the inlet of the evaporator. The dryer filter 65 can dry and filter out moisture and impurities in the refrigerant, thereby increasing the cooling capacity of the refrigerant entering the evaporator, thus reducing the refrigeration power and saving energy.

[0080] like Figure 7 As shown, in some embodiments, the refrigeration system 60 further includes a capillary tube disposed between the outlet of the condenser 63 and the inlet of the evaporator. The capillary tube is a throttling device that can throttle the refrigerant, reduce the refrigerant pressure, and make the refrigerant mainly liquid at the end of the capillary tube, thereby improving the operating efficiency of the evaporator.

[0081] For example, the capillary includes a chilled water capillary 661 and an ice-making capillary 662. The end of the chilled water capillary 661 is connected to a chilled water evaporator 641 to throttle and reduce the pressure of the refrigerant entering the chilled water evaporator 641. The end of the ice-making capillary 662 is connected to an ice-making evaporator 642 to throttle and reduce the pressure of the refrigerant entering the ice-making evaporator 642.

[0082] like Figure 7 As shown, in some embodiments, the end of the dryer filter 65 is connected to an electric valve 67. The electric valve 67 is connected to an ice-making evaporator 642 and a refrigerant water evaporator 641 via two pipes, one of which is equipped with an ice-making capillary tube 662, and the other with a refrigerant water capillary tube 661. The amount of refrigerant entering the refrigerant water evaporator 641 and the ice-making evaporator 642 can be controlled by the electric valve 67 to meet the corresponding refrigeration and ice-making requirements.

[0083] like Figure 7 As shown, in some embodiments, the refrigeration system 60 further includes a return pipe 68, through which the evaporator is connected to the compressor 61, so that the refrigerant flowing out of the evaporator can flow back to the compressor 61 through the return pipe 68, forming a refrigeration flow path circulation.

[0084] For example, the return pipe 68 is connected to the refrigerant evaporator 641 and the ice evaporator 642 respectively via a three-way pipe, so that the refrigerant in the refrigerant evaporator 641 and the refrigerant in the ice evaporator 642 can both flow back to the compressor 61 through the return pipe.

[0085] In this embodiment, when cooling water and making ice through the refrigeration system 60, the compressor 61 starts, and the refrigerant is compressed in the cylinder of the compressor 61, becoming a high-temperature, high-pressure refrigerant, which is then discharged from the exhaust pipe of the compressor 61. After passing through the heat dissipation pipe 62, the high-temperature, high-pressure refrigerant exchanges heat with the wastewater in the wastewater tank 51, and the temperature of the refrigerant is initially reduced, and then it is sent to the condenser 63. The refrigerant is cooled and condensed into a high-pressure liquid by the condenser 63, then passes through the dryer filter 65, and then flows to the electric valve 67. According to the needs of ice making and cooling water, the refrigerant can flow to the ice-making capillary tube 662 and then be sent to the ice-making evaporator 642 to make ice cubes, and / or, the refrigerant can flow to the cooling water capillary tube 661 and then be sent to the cooling water evaporator 641 to make cold water. After absorbing heat and vaporizing in the ice-making evaporator 642 and / or the chilled water evaporator 641, the refrigerant flows out of the ice-making evaporator 642 and / or the chilled water evaporator 641, and is drawn back to the compressor 61 through the return pipe 68, forming a refrigeration flow loop. When the water temperature in the chilled water module 41 reaches the shutdown setpoint, the compressor 61 stops, or the electric valve 67 switches its path to stop supplying refrigerant to the chilled water evaporator 641. When the user connects to chilled water, the warm water module 30 can replenish water to the chilled water module 41, raising the temperature inside the chilled water module 41, and the refrigeration system 60 restarts to refrigerate the chilled water module 41. When the ice-making module 42 is full of ice, the compressor 61 stops, or the electric valve 67 switches its path to stop supplying refrigerant to the ice-making evaporator 642. When the user removes the ice, the amount of ice in the ice-making module 42 decreases, and the refrigeration system 60 restarts to make ice in the ice-making module 42.

[0086] In this application, the chilled water dispenser can automatically control the flow of water and the operation of various modules and the refrigeration system 60 through its internal electrical system, so as to realize automated ice making, chilled water making, warm water making, and hot water making, thereby meeting the user's needs.
