[0002] Currently, water dispensers with refrigeration functions are generally equipped with a cold water refrigeration system and a refrigerator refrigeration system, which are arranged in series. During use, if the temperature detection mechanism detects that the cold water temperature has not reached the target temperature, the cooling fan, compressor, and other refrigeration components need to be turned on in sequence, so that the refrigerant passes through the condenser, dryer filter, throttling device, cold water tank evaporator, refrigerator evaporator, and circulates back to the compressor. Conversely, if the temperature detection mechanism detects that the cold water temperature has reached the target temperature, the compressor, cooling fan, and other refrigeration components need to be turned off in sequence, so that the refrigeration system stops working. As a result, the temperature of the cold water and the refrigerator compartment is very similar, which is difficult to meet the needs of different operating conditions.

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] The core of this application is to provide a hot and cold water dispenser system with a refrigeration function, capable of independently adjusting the cold water temperature and the refrigeration compartment temperature to meet the needs of different operating conditions. Another core aspect of this application is to provide a hot and cold water dispenser that includes the aforementioned hot and cold water dispenser system with a refrigeration function.

[0046] This application provides a hot and cold water dispenser system with refrigeration function, including a refrigerator compartment refrigeration component 1, a cold tank refrigeration component 2, a refrigerant power component 3, and a reversing valve assembly 4; wherein, the refrigerator compartment refrigeration component 1 is used to refrigerate the refrigerator compartment; the cold tank refrigeration component 2 is used to refrigerate the cold tank; the refrigerant power component 3 is used to provide refrigerant to the refrigerator compartment refrigeration component 1 and the cold tank refrigeration component 2; the reversing valve assembly 4 is located at the inlet end of the refrigerator compartment refrigeration component 1 and the cold tank refrigeration component 2, and is used to control the refrigerator compartment refrigeration component 1 and the cold tank refrigeration component 2 to be simultaneously or individually connected to the refrigerant power component 3.

[0047] refer to Figure 1 As explained, the hot and cold water dispenser system is equipped with a refrigerator compartment refrigeration component 1 and a cold tank refrigeration component 2, which can refrigerate the refrigerator compartment and the cold tank respectively. To ensure that the refrigerator compartment refrigeration component 1 and the cold tank refrigeration component 2 can work normally, the hot and cold water dispenser system is equipped with a refrigerant power component 3. The outlet of the refrigerant power component 3 is connected to the inlet of the refrigerator compartment refrigeration component 1 and the cold tank refrigeration component 2, and the inlet of the refrigerant power component 3 is connected to the outlet of the refrigerator compartment refrigeration component 1 and the cold tank refrigeration component 2. The refrigerant power component 3 can serve as the starting point and ending point of the system circulation. After pushing the refrigerant out, it can flow through the refrigerator compartment refrigeration component 1 and the cold tank refrigeration component 2 and then return to it, realizing cyclical refrigeration.

[0048] The beneficial effects are that, in order to facilitate the selection of the refrigeration component 1 of the refrigerator compartment and / or the refrigeration component 2 of the cold tank for refrigeration, the hot and cold water dispenser system is also equipped with a reversing valve assembly 4. The reversing valve assembly 4 can be used to connect the inlet of the refrigeration component 1 of the refrigerator compartment and / or the inlet of the refrigeration component 2 of the cold tank to the refrigerant power assembly 3. Conversely, the reversing valve assembly 4 can be used to close the inlet of the refrigeration component 1 of the refrigerator compartment and / or the inlet of the refrigeration component 2 of the cold tank to the refrigerant power assembly 3 to meet different operating conditions. Compared with related technologies, the hot and cold water dispenser system has better energy-saving performance and lower failure rate and material cost.

[0049] Based on the above embodiments, the reversing valve assembly 4 includes a first reversing valve 41 and a second reversing valve 42. Both the first reversing valve 41 and the second reversing valve 42 have an inlet A, an outlet B, and an outlet C. The inlet A of the first reversing valve 41 can be selectively connected to either outlet B or outlet C, and the inlet A of the second reversing valve 42 can be selectively connected to either outlet B or outlet C. The inlet A of the first reversing valve 41 is connected to the outlet end of the refrigerant power assembly 3, the outlet C of the first reversing valve 41 is connected to the inlet end of the refrigerator compartment refrigeration assembly 1, and the outlet B of the first reversing valve 41 is connected to the inlet end of the cold tank refrigeration assembly 2. The inlet A of the second reversing valve 42 is connected to the outlet end of the refrigerator compartment refrigeration assembly 1, the outlet B of the second reversing valve 42 is connected to the inlet end of the cold tank refrigeration assembly 2, and the outlet C of the second reversing valve 42 is connected to the inlet end of the refrigerant power assembly 3. The outlet end of the cold tank refrigeration assembly 2 is connected to the inlet end of the refrigerant power assembly 3.

[0050] Both the first directional valve 41 and the second directional valve 42 include an inlet A, an outlet B, and an outlet C. The first directional valve 41 and the second directional valve 42 can be three-position four-way valves of the neutral O type or... Figure 2 The two-position three-way valve shown is an example.

[0051] The outlet of the refrigeration unit 1 in the refrigerator compartment and the outlet of the refrigeration unit 2 in the cold tank are respectively connected to the first medium return pipeline and the second medium return pipeline, so that the refrigerant can circulate back to the refrigerant power unit 3 when the refrigeration unit 1 in the refrigerator compartment and / or the refrigeration unit 2 in the cold tank are refrigerating.

[0052] The outlet of the refrigerant power assembly 3 is connected to an independent first branch pipe and a second branch pipe through outlet A and outlet B of the first reversing valve 41. The first branch pipe is connected to the refrigerator compartment refrigeration assembly 1, and the second branch pipe is connected to the cold tank refrigeration assembly 2. By adjusting the working position of the first reversing valve 41, either the refrigerator compartment refrigeration assembly 1 or the cold tank refrigeration assembly 2 can be selected for refrigeration.

[0053] In addition to the second branch pipe connected to the cold tank refrigeration component 2, a third branch pipe is added to the inlet of the cold tank refrigeration component 2. Correspondingly, a second reversing valve 42 is installed at the outlet end of the cold storage compartment refrigeration component 1. The outlet of the cold storage compartment refrigeration component 1 is connected to the independent first medium return pipe and the third branch pipe through the outlet A and outlet B of the second reversing valve 42. By adjusting the working position of the second reversing valve 42, the circulation requirements of the cold storage compartment refrigeration component 1 for individual refrigeration can be met, as well as the requirement of connecting the cold storage compartment refrigeration component 1 and the cold tank refrigeration component 2 in series for simultaneous refrigeration.

[0054] When both the refrigerator compartment refrigeration unit 1 and the cold storage tank refrigeration unit 2 need to cool simultaneously, please refer to... Figure 3By controlling the inlet A and outlet C of the first reversing valve 41 to be open, and controlling the inlet A and outlet B of the second reversing valve 42 to be open, the refrigerant passes through the refrigerant power assembly 3, the first reversing valve 41, the refrigerator compartment refrigeration assembly 1, the second reversing valve 42, the cold tank refrigeration assembly 2, and the refrigerant power assembly 3 in sequence to achieve a refrigeration cycle.

[0055] If you require separate cooling from refrigerator compartment refrigeration unit 1, please refer to [the relevant documentation]. Figure 4 By controlling the inlet A and outlet C of the first reversing valve 41 to be open, and controlling the inlet A and outlet C of the second reversing valve 42 to be open, the refrigerant passes through the refrigerant power assembly 3, the first reversing valve 41, the refrigerator compartment refrigeration assembly 1, the second reversing valve 42, and the refrigerant power assembly 3 in sequence to achieve a refrigeration cycle.

[0056] If the cold tank refrigeration unit 2 requires independent refrigeration, please refer to [the relevant documentation]. Figure 5 When the inlet A and outlet B of the first reversing valve 41 are opened, the refrigerant passes through the refrigerant power assembly 3, the first reversing valve 41, the cold tank refrigeration assembly 2, and the refrigerant power assembly 3 in sequence to achieve a refrigeration cycle.

[0057] Of course, in some embodiments, the positions of the refrigerator compartment refrigeration component 1 and the cold tank refrigeration component 2 can be interchanged, and it is still possible to select the refrigerator compartment refrigeration component 1 and / or the cold tank refrigeration component 2 for refrigeration.

[0058] Based on the above embodiments, the refrigerator compartment refrigeration assembly 1 includes a refrigerator compartment evaporator 11 and a first throttle valve 12. The outlet C of the first reversing valve 41 is connected to the inlet of the first throttle valve 12, and the outlet of the first throttle valve 12 is connected to the inlet of the refrigerator compartment evaporator 11. The cold tank refrigeration assembly 2 includes a cold tank evaporator 21 and a second throttle valve 22. The outlet B of the second reversing valve 42 is connected to the inlet of the second throttle valve 22, and the outlet of the second throttle valve 22 is connected to the inlet of the cold tank evaporator 21.

[0059] refer to Figure 1 As explained, the cold tank and the cold storage compartment are equipped with separate expansion valves and evaporators. Specifically, in the cold storage compartment refrigeration assembly 1, the first expansion valve 12 is located at the inlet end of the cold storage compartment evaporator 11, that is, it is set in the first branch pipe, and the outlet of the cold storage compartment evaporator 11 is connected to the inlet A of the second reversing valve 42; similarly, in the cold tank refrigeration assembly 2, the second expansion valve 22 is located at the inlet end of the cold tank evaporator 21, that is, it is set in the second branch pipe.

[0060] When using the refrigerator compartment refrigeration unit 1 for independent cooling, please refer to... Figure 4 After the refrigerant flows out of the refrigerant power assembly 3, it will first flow through the first throttle valve 12, then through the evaporator 11 of the refrigerator compartment, and then circulate back into the refrigerant power assembly 3.

[0061] When using the cold tank refrigeration unit 2 for refrigeration alone, please refer to... Figure 5 After the refrigerant flows out of the refrigerant power assembly 3, it will first flow through the second throttle 22, then through the cold tank evaporator 21, and then circulate back into the refrigerant power assembly 3.

[0062] When using both the refrigerator compartment refrigeration unit 1 and the cold tank refrigeration unit 2 for simultaneous refrigeration, please refer to... Figure 3 After the refrigerant flows out of the refrigerant power assembly 3, it will flow sequentially through the first throttle valve 12, the refrigerator compartment evaporator 11, the second reversing valve 42, and the cold tank evaporator 21, and then flow back into the refrigerant power assembly 3 after passing through the refrigerator compartment evaporator 11.

[0063] The throttling device can control the refrigerant flow, pressure, and temperature, creating a low-temperature and low-pressure environment for the evaporator to achieve effective refrigeration. Since the cold tank and the cold storage compartment are equipped with separate throttling devices and evaporators, the refrigerant flow in the cold tank and the cold storage compartment can be intelligently adjusted according to the working mode to achieve a reasonable working temperature, further improving the energy efficiency ratio of the refrigeration system and achieving further energy saving.

[0064] In some possible embodiments, the refrigerator compartment refrigeration assembly 1 includes only the refrigerator compartment evaporator 11, and the cold tank refrigeration assembly 2 includes only the cold tank evaporator 21.

[0065] Based on the above embodiment, the outlet C of the second reversing valve 42 is connected to the first end of the first medium return pipeline, the outlet of the cold tank evaporator 21 is connected to the first end of the second medium return pipeline, the second end of the first medium return pipeline and the second end of the second medium return pipeline are both connected to the medium return main pipeline, and the medium return main pipeline is connected to the inlet of the refrigerant power assembly 3; it also includes a first check valve 5 and a second check valve 6, the first check valve 5 is provided in the first medium return pipeline, and the second check valve 6 is provided in the second medium return pipeline.

[0066] refer to Figure 1 As explained, in order to meet the refrigerant reflux and achieve circulation, the hot and cold water dispenser system is equipped with a first refrigerant reflux pipeline, a second refrigerant reflux pipeline, and a main refrigerant reflux pipeline. One end of the first refrigerant reflux pipeline is connected to the outlet C of the second one-way valve 6, and the other end is connected to the main refrigerant reflux pipeline. One end of the second refrigerant reflux pipeline is connected to the outlet of the cold tank evaporator 21, and the other end is connected to the main refrigerant reflux pipeline. The main refrigerant reflux pipeline also has one end connected to the inlet of the refrigerant power assembly 3.

[0067] When using the refrigerator compartment refrigeration unit 1 for independent cooling, please refer to... Figure 4 After the refrigerant flows out of the evaporator 11 in the refrigerator compartment, it will first flow through the first medium return pipeline, then through the medium return main pipeline, and finally circulate back into the refrigerant power assembly 3.

[0068] When using the cold tank refrigeration unit 2 for refrigeration alone, or when using the refrigerator compartment refrigeration unit 1 and the cold tank refrigeration unit 2 for refrigeration simultaneously, please refer to... Figure 5 and Figure 3 After the refrigerant flows out of the evaporator 21 of the cold tank, it will first flow through the second medium return pipeline, then through the medium return main pipeline, and finally circulate back into the refrigerant power assembly 3.

[0069] Each of the cold tank and the cold compartment is equipped with a separate one-way valve. Specifically, the first one-way valve 5 is installed in the first medium return pipeline. When the cold tank refrigeration component 2 is in the independent refrigeration mode or when the cold tank refrigeration component 2 and the cold compartment refrigeration component 1 are in the simultaneous refrigeration mode, or when the refrigerant is transferred using the second medium return pipeline, the refrigerant will not flow back to the second one-way valve 6. The second one-way valve 6 is installed in the second medium return pipeline. When the cold compartment refrigeration component 1 is in the independent refrigeration mode or when the refrigerant is transferred using the first medium return pipeline, the refrigerant will not flow back to the cold tank evaporator 21.

[0070] In short, the hot and cold water dispenser system in this embodiment is equipped with two one-way valves to control the one-way flow of refrigerant and to easily control the direction of refrigerant circulation, so as to meet the needs of simultaneous cooling mode of the refrigerator compartment and the cold tank, cooling mode of the refrigerator compartment alone, and cooling mode of the cold tank alone. In conjunction with the first reversing valve 41 and the second reversing valve 42, it can also meet the need to shut off the cooling, and can further achieve the purpose of energy saving and precise temperature control.

[0071] Based on the above embodiments, the refrigerator compartment refrigeration component 1 includes a refrigerator compartment temperature acquisition device 13 for acquiring the temperature of the refrigerator compartment, and the cold tank refrigeration component 2 includes a cold tank temperature acquisition device 23 for acquiring the temperature of the liquid in the cold tank; it also includes a controller, which is signal-connected to the refrigerator compartment temperature acquisition device 13, the cold tank temperature acquisition device 23 and the refrigerant power component 3, for receiving the detection results of the refrigerator compartment temperature acquisition device 13 and the cold tank temperature acquisition device 23, and controlling the start and stop of the refrigerator compartment evaporator 11, the cold tank evaporator 21 and the refrigerant power component 3.

[0072] When the refrigerator compartment refrigeration unit 1 is used for independent refrigeration, after receiving the temperature data from the refrigerator compartment temperature acquisition unit 13 and the cold tank temperature acquisition unit 23, the controller compares the temperature data of the refrigerator compartment temperature acquisition unit 13 with the target temperature of the refrigerator compartment, and compares the temperature data of the cold tank temperature acquisition unit 23 with the target temperature of the cold tank. If the temperature data of the refrigerator compartment temperature acquisition unit 13 is equal to the target temperature of the refrigerator compartment, a command is sent to the refrigerator compartment evaporator 11 to control the refrigerator compartment evaporator 11 to stop working, that is, to stop the refrigeration work of the refrigerator compartment. If the temperature data of the cold tank temperature acquisition unit 23 is equal to the target temperature of the cold tank, a command is sent to the cold tank evaporator 21 to control the cold tank evaporator 21 to stop working, that is, to stop the refrigeration work of the cold tank. If the temperature data of the cold tank temperature acquisition unit 23 is equal to the target temperature of the cold tank, and at the same time, the temperature data of the refrigerator compartment temperature acquisition unit 13 is equal to the target temperature of the refrigerator compartment, a command is sent to the refrigerant power unit 3 to control the refrigerant power unit 3 to stop working, thereby stopping the refrigeration work of the entire system.

[0073] When the cold tank refrigeration component 2 is used for refrigeration alone, after the controller receives the temperature data from the cold tank temperature acquisition device 23, it will compare the temperature data of the cold tank temperature acquisition device 23 with the target temperature of the cold tank. If the temperature data of the cold tank temperature acquisition device 23 is equal to the target temperature of the cold tank, it will send a command to the cold tank evaporator 21 to control the cold tank evaporator 21 and the refrigerant power component 3 to stop working, stop the refrigeration work of the cold tank, that is, stop the refrigeration work of the entire system.

[0074] When the refrigerator compartment refrigeration unit 1 and the refrigerator compartment refrigeration unit 1 are used for refrigeration at the same time, after the controller receives the temperature data from the refrigerator compartment temperature acquisition unit 13, it will compare the temperature data from the refrigerator compartment temperature acquisition unit 13 with the target temperature of the refrigerator compartment. If the temperature data from the refrigerator compartment temperature acquisition unit 13 is equal to the target temperature of the refrigerator compartment, it will send a command to the refrigerator compartment evaporator 11 to control the refrigerator compartment evaporator 11 and the refrigerant power unit 3 to stop working, stop the refrigeration work of the refrigerator compartment, that is, stop the refrigeration work of the entire system.

[0075] It should be noted that there are no restrictions on the type of the refrigerator compartment temperature acquisition device 13 and the cold tank temperature acquisition device 23, as long as they can meet the temperature acquisition requirements.

[0076] Optionally, the refrigerator compartment temperature acquisition device 13 and the cold tank temperature acquisition device 23 can be temperature detectors such as temperature sensors or temperature probes to acquire temperature data through direct detection. When using temperature detectors, they can be installed inside the corresponding refrigerator compartment or cold tank, or in the refrigerator compartment evaporator 11 or the cold tank evaporator 21, etc.

[0077] Optionally, the refrigerator compartment temperature acquisition device 13 and the cold tank temperature acquisition device 23 can be sub-controllers, which can receive the temperature parameters of the refrigerator compartment and the cold tank, and can transmit the temperature data to the controller.

[0078] Based on the above embodiments, the refrigerant power assembly 3 includes a compressor 31, a radiator 32, and a dryer filter 33; the outlet of the compressor 31 is connected to the inlet of the radiator 32, and the outlet of the radiator 32 is connected to the inlet of the dryer filter 33; the outlet of the dryer filter 33 is connected to the inlet A of the first reversing valve 41.

[0079] refer to Figure 1 As explained, the compressor 31, radiator 32, and dryer filter 33 are connected in series, and the outlet of the dryer filter 33 is connected to the inlet A of the first reversing valve 41. The inlet of the compressor 31 is connected to the medium return main pipeline. When using the refrigerant power assembly 3 for refrigeration, the refrigerant will pass through the compressor 31, radiator 32, and dryer filter 33 in sequence, and then flow into the refrigerator compartment refrigeration assembly 1 and / or the cold tank refrigeration assembly 2, and finally circulate back to the compressor 31 through the medium return main pipeline. Correspondingly, the above-mentioned control of the refrigerant power assembly 3 to stop working refers to control the compressor 31 to stop working.

[0080] In this embodiment, the compressor 31 compresses and delivers the gaseous refrigerant to achieve pressure boosting, heat transfer, and fluid drive in the refrigeration cycle; the dryer filter 33 can absorb moisture and filter impurities in the hot and cold water dispenser system to prevent ice blockage and dirt blockage; and the radiator 32 can remove heat from the hot and cold water dispenser system, which helps to ensure the normal operation of the hot and cold water dispenser system.

[0081] refer to Figure 1 As can be seen, based on the above embodiments, the refrigerant power assembly 3 also includes a cooling fan 34, which faces the radiator 32. The strong airflow generated by the operation of the cooling fan 34 accelerates the dissipation of heat from the surface of the radiator 32, thereby maintaining the normal operating temperature of the refrigerant.

[0082] Based on the above embodiments, the controller includes a delay module. The delay module is signal-connected to the cooling fan 34 and the compressor 31. It is used to receive the signal that the compressor 31 stops working and control the cooling fan 34 to stop working after a delay of a target time. This allows the controller to control the cooling fan 34 to stop after the entire hot and cold water dispenser system stops cooling, thereby ensuring the cooling effect of the radiator 32.

[0083] In some possible embodiments, the delay module employs a delay chip equipped with a delay program, and the delay chip's program is run during controller operation to achieve the delay.

[0084] In some possible embodiments, the delay module uses a timer. The timer signal is connected to the main program of the controller. After the timer finishes counting, it sends an interrupt signal to the main program. The main program executes the interrupt service routine to control the cooling fan 34 to stop working.

[0085] Of course, the delay module is not limited to the types of examples mentioned above; it can be used as long as it can meet the delay requirements.

[0086] It should be noted that the reversing valve assembly 4 is not limited to the example type in the above embodiments. As long as it can meet its functional requirements, it is acceptable. For example, the reversing valve assembly 4 includes a three-position four-way reversing valve. The middle position of the three-position four-way reversing valve is P-type, that is, the inlet of the three-position four-way reversing valve is connected to both the first outlet and the second outlet in the middle position. The left position is connected to the inlet and the first outlet, and the right position is connected to the inlet and the second outlet. The inlet of the refrigerator compartment refrigeration component 1 is connected to the first outlet of the three-position four-way reversing valve, and the inlet of the cold tank refrigeration component 2 is connected to the second outlet of the three-position four-way reversing valve. When the three-position four-way reversing valve is in the middle position, both the refrigerator compartment refrigeration component 1 and the cold tank refrigeration component 2 are connected to the refrigerant power component 3. When the three-position four-way reversing valve is in the left position, the refrigerator compartment refrigeration component 1 is connected to the refrigerant power component 3. When the three-position four-way reversing valve is in the right position, the cold tank refrigeration component 2 is connected to the refrigerant power component 3.

[0087] In addition to the above-mentioned hot and cold water dispenser system with refrigeration function, this application also provides a hot and cold water dispenser that includes the hot and cold water dispenser system with refrigeration function disclosed in the above embodiments. For the structure of other parts of the hot and cold water dispenser with refrigeration function, please refer to the prior art, and it will not be described in detail here.
