Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, and in particular to a refrigeration system and a water dispenser. Background Technology

[0002] Water dispensers or direct drinking water machines are common drinking water equipment in daily life, offering various supply modes including room temperature water, chilled water, and ice making. With changing lifestyles, the demand for ice and iced water is increasing.

[0003] In related technologies, water dispensers simultaneously produce boiling water, warm water, cold water, and ice, with all water and ice derived from boiled water. However, because the refrigeration and ice-making modules of the water dispenser are connected in series, and the compressor's operation is controlled by a thermometer in the refrigeration module, there are technical problems such as fluctuations in the cold water tank temperature affecting ice-making quality, lack of independent control for the ice-making function leading to unstable operation, and a decline in cold water quality during the de-icing process.

The third port of the first tee pipe is connected to the main cooling medium pipe.

[0011] In the refrigeration system of this application, a water supply pipe is connected between the cold water tank and the refrigerator, and a water pump is provided on the water supply pipe. The water pump is used to drive the cold water in the cold water tank into the refrigerator through the water supply pipe.

[0013] The inlet pipe is equipped with an inlet valve, and / or the outlet pipe is equipped with an outlet valve.

[0014] In the refrigeration system of this application, the ice-making module includes a support plate for carrying cold water and a drive motor. The support plate is located below the ice-making evaporator and is rotatably disposed in the ice-making refrigerator in a horizontal direction.

[0015] In the refrigeration system of this application, the ice-making module includes a water-drawing pipe and a water-drawing pump.

[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0028] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other.

[0029] like Figure 1As shown, this utility model embodiment provides a refrigeration system for a water dispenser, including a refrigeration module, an ice-making module, and a cooling module. The refrigeration module includes a cold water tank 11 and a refrigeration evaporator 12, with the refrigeration evaporator 12 disposed inside the cold water tank 11. The ice-making module includes a refrigerator 21 and an ice-making evaporator 22, with the ice-making evaporator 22 disposed inside the refrigerator 21. The cooling module includes a cooling component 31, a cooling medium main pipe 32, and a switching valve 33. The cooling component 31 and the switching valve 33 are disposed on the cooling medium main pipe 32. The cooling component 31 is used to drive the cooling medium to flow through the cooling medium main pipe 32 to the switching valve 33. The switching valve 33 is connected to the inlet of the refrigeration evaporator 12 through a first capillary tube 41 and is also connected to the inlet of the ice-making evaporator 22 through a second capillary tube 42. The outlet of the refrigeration evaporator 12 and the outlet of the ice-making evaporator 22 are connected to the cooling component 31 through the cooling medium main pipe 32.

[0030] In this embodiment, the cooling medium is specifically a cooling medium such as Freon or ammonia.

[0031] The refrigeration module includes a cold water tank 11 and a refrigeration evaporator 12 disposed within the cold water tank 11. The working principle of the refrigeration evaporator 12 is as follows: When the liquid cooling medium flows through the evaporator, due to the pressure reduction, the liquid cooling medium evaporates into a gaseous cooling medium. During the evaporation process, the cooling medium absorbs heat from the water in the cold water tank 11, thereby lowering the water temperature. Subsequently, the gaseous cooling medium is recompressed into a liquid state, thus completing the refrigeration cycle.

[0032] The ice-making module includes a refrigerator 21 and an ice-making evaporator 22 located within the refrigerator 21. The working principle of the ice-making evaporator 22 is similar to that of the refrigeration evaporator 12, both based on the principle of evaporative refrigeration. The difference is that when the liquid cooling medium flows through the ice-making evaporator 22, it will rapidly evaporate and absorb the heat of the water in the refrigerator 21, thereby gradually cooling the water and solidifying it into ice.

[0033] The cooling module includes a cooling component 31, a cooling medium main pipe 32, and a switching valve 33. The cooling component 31 and the switching valve 33 are located on the cooling medium main pipe 32. The cooling component 31 is used to drive the cooling medium to circulate within the cooling medium main pipe 32.

[0034] In some embodiments, the cooling assembly 31 includes a compressor 311, a condenser 312, and a dryer filter 313; the first end of the compressor 311 is connected to the third port of the first tee pipe 14, the second end of the compressor 311 is connected to the first end of the condenser 312, the second end of the condenser 312 is connected to the first end of the dryer filter 313, and the second end of the dryer filter 313 is connected to the switching valve 33.

[0035] The compressor 311 is used to compress the low-temperature, low-pressure cooling medium gas into a high-temperature, high-pressure gas. The first end (i.e., the suction port) of the compressor 311 is connected to the third port of the first three-way pipe 14 through the cooling medium main pipe 32 to receive the cooling medium gas from the refrigeration evaporator 12 or the ice-making evaporator 22; the second end (i.e., the discharge port) of the compressor 311 is connected to the first end of the condenser 312 through the cooling medium main pipe 32 to send the compressed cooling medium gas into the condenser 312 for condensation.

[0036] The condenser 312 is used to cool and liquefy the high-temperature and high-pressure cooling medium gas discharged from the compressor 311 and release heat to the external environment. The second end of the condenser 312 is connected to the first end (i.e., the inlet) of the dryer filter 313 through the cooling medium main pipe 32, so that the liquefied cooling medium is sent into the dryer filter 313 for purification.

[0037] The dryer filter 313 is used to remove moisture and impurities from the cooling medium, preventing them from corroding and clogging the system. The second end (i.e., the outlet) of the dryer filter 313 is connected to the switching valve 33 through the cooling medium main pipe 32, through which the liquefied cooling medium is sent to the refrigeration module or the ice-making module.

[0038] The refrigeration unit operates as follows: The compressor 311 is started, compressing the low-temperature, low-pressure gaseous cooling medium in the cooling medium main pipe 32 into a high-temperature, high-pressure gaseous cooling medium. Then, the high-temperature, high-pressure gaseous cooling medium enters the condenser 312 for condensation and heat release, becoming a high-temperature, high-pressure liquid cooling medium. Next, the liquid cooling medium passes through the dryer filter 313 for drying and filtration to remove moisture and other substances.

[0039] Furthermore, the switching valve 33 has two outlet pipes. The first outlet pipe is connected to the inlet of the refrigeration evaporator 12 via the first capillary tube 41, and the second outlet pipe is connected to the inlet of the ice-making evaporator 22 via the second capillary tube 42. The outlets of both the refrigeration evaporator 12 and the ice-making evaporator 22 are connected to the cooling assembly 31 via the cooling medium main pipe 32, forming a closed-loop circulation circuit for the cooling medium. Both the first capillary tube 41 and the second capillary tube 42 are throttling structures used to reduce the pressure of the high-temperature, high-pressure liquid cooling medium into a low-temperature, low-pressure liquid cooling medium.

[0040] Based on the above technical solution, when cooling is required, the cooling assembly 31 is activated, driving the cooling medium to flow within the cooling medium main pipe 32. Through the switching action of the switching valve 33, the cooling medium can enter either the refrigeration evaporator 12 or the ice-making evaporator 22. If the refrigeration system is in cooling mode, the switching valve 33 is switched to the first capillary tube 41, allowing the cooling medium to enter the refrigeration evaporator 12. Within the refrigeration evaporator 12, the cooling medium absorbs heat from the cold water tank 11, lowering the water temperature and forming cold water. Afterward, the cooling medium flows out from the outlet of the refrigeration evaporator 12 and returns to the cooling assembly 31 via the cooling medium main pipe 32 for further cooling. If the refrigeration system is in ice-making mode, the switching valve 33 is switched to the second capillary tube 42, allowing the cooling medium to enter the ice-making evaporator 22. Within the ice-making evaporator 22, the cooling medium absorbs heat from the ice-making refrigerator 21, causing the water to gradually freeze. Once the ice cubes reach a predetermined size, they are removed from the ice-making refrigerator 21. After de-icing, the cooling medium flows out from the outlet of the ice-making evaporator 22 and returns to the cooling assembly 31 through the cooling medium main pipe 32 for circulation.

[0041] In this embodiment, the switching valve 33 can be a three-way electric valve or a three-way solenoid valve. The switching valve 33 can be switched to the first capillary tube 41 or the second capillary tube 42 respectively, so that the ice-making process and the cooling water process are independent of each other and do not interfere with each other, thereby effectively improving the ice-making quality and the quality of the cooling water.

[0042] In some embodiments, the refrigeration module includes a first return pipe 13 and a first tee pipe 14. One end of the first return pipe 13 is connected to the outlet of the refrigeration evaporator 12, and the other end of the first return pipe 13 is connected to the first port of the first tee pipe 14. The ice-making module includes a second return pipe 23. One end of the second return pipe 23 is connected to the outlet of the ice-making evaporator 22, and the other end of the second return pipe 23 is connected to the second port of the first tee pipe 14. The third port of the first tee pipe 14 is connected to the cooling medium main pipe 32.

[0043] Specifically, the first three-way pipe 14 is a three-way pipe structure with three interfaces: a first interface, a second interface, and a third interface, allowing the three pipes to be connected at the three interfaces respectively. In this embodiment, one end of the first return gas pipe 13 is connected to the outlet of the refrigeration evaporator 12 to receive the cooling medium evaporated in the refrigeration evaporator 12, and the other end of the first return gas pipe 13 is connected to the first interface of the first three-way pipe 14 to realize the connection between the return gas of the refrigeration module and the cooling module. Similarly, one end of the second return gas pipe 23 is connected to the outlet of the ice-making evaporator 22 to receive the cooling medium evaporated in the ice-making evaporator 22, and the other end of the second return gas pipe 23 is connected to the second interface of the first three-way pipe 14 to realize the connection between the return gas of the ice-making module and the cooling module. Further, the third interface of the first three-way pipe 14 is connected to the cooling medium main pipe 32 to transport the evaporated cooling medium to the cooling assembly 31 for circulation.

[0044] When the refrigeration system starts, the cooling assembly 31 begins to work, driving the cooling medium to circulate within the cooling medium main pipe 32. The refrigeration evaporator 12 or ice-making evaporator 22 is activated to absorb heat from the cold water tank 11 or refrigerator 21, causing the cooling medium to evaporate and form a low-temperature gas. The cooling medium evaporated in the refrigeration evaporator 12 enters the first port of the first three-way pipe 14 through the first return pipe 13. The cooling medium evaporated in the ice-making evaporator 22 enters the second port of the first three-way pipe 14 through the second return pipe 23. The evaporated cooling medium then enters the cooling medium main pipe 32 through the third port of the first three-way pipe 14, returning to the cooling assembly 31 for compression, condensation, and recirculation.

[0045] In some embodiments, a water supply pipe 15 is connected between the cold water tank 11 and the refrigerator 21, and a water pump 16 is provided on the water supply pipe 15. The water pump 16 is used to drive the cold water in the cold water tank 11 into the refrigerator 21 through the water supply pipe 15.

[0046] Specifically, the cold water tank 11 is used to store cooled cold water, and the refrigerator 21 uses the cold water in the cold water tank 11 as a water source for ice making. When ice making is required, the water pump 16 is started to transport the cold water in the cold water tank 11 to the refrigerator 21 through the water pipe 15.

[0047] It should be understood that the water dispenser also includes a control system (not shown), which is electrically connected to the refrigeration system. When the refrigeration system is started, the control system detects the status of the cold water tank 11 and the refrigerator 21, as well as parameters such as the initial flow rate and pressure in the water supply pipe 15. Then, the control system sends a command to the water pump 16, driving the water pump 16 to run and transport the cold water in the cold water tank 11 to the refrigerator 21 through the water supply pipe 15.

[0048] In some embodiments, the control system can monitor parameters such as flow rate and pressure in the water supply pipe 15 in real time through flow sensors and pressure sensors. When the cold water flow rate is lower or higher than a preset threshold, the control system adjusts the speed or power of the water pump 16 accordingly to achieve precise flow rate control and avoid excessive or insufficient cold water flow rate.

[0049] In some embodiments, the refrigeration module includes an inlet pipe 17 and an outlet pipe 18, with the inlet pipe 17 connected to the top of the cold water tank 11 and the outlet pipe 18 connected to the bottom of the cold water tank 11.

[0050] Specifically, the inlet pipe 17 is connected to the top of the cold water tank 11 to introduce external water into the cold water tank 11. The outlet pipe 18 is connected to the bottom of the cold water tank 11 to deliver the cold water cooled by the evaporator 12 in the cold water tank 11 for user use.

[0051] In some embodiments, an inlet valve is provided on the inlet pipe 17, which is used to regulate the inlet water flow rate into the cold water tank 11. The inlet valve can be a manual valve, an electric valve, or a solenoid valve.

[0052] In some embodiments, the water outlet pipe 18 is provided with a water outlet valve, which is used to regulate the water flow rate out of the cold water tank 11. The water outlet valve can be a manual valve, an electric valve, or a solenoid valve.

[0053] In some embodiments, the refrigeration module includes a first temperature monitoring device 19 for monitoring the temperature of the cold water in the cold water tank 11. Specifically, the first temperature monitoring device 19 may be a temperature sensor.

[0054] In some embodiments, the ice-making module includes a support plate 24 for carrying cold water and a drive motor 25. The support plate 24 is located below the ice-making evaporator 22 and is rotatably disposed in the refrigerator 21 in a horizontal direction. The drive motor 25 is used to drive the support plate 24 to flip inside the refrigerator 21.

[0055] Specifically, the support tray 24, also called the ice-making water tray, can be circular, square, or other shapes. The drive motor 25 is connected to the support tray 24 through a transmission device (such as gears, chains, or belts) to drive the support tray 24 to rotate vertically.

[0056] In use, the support plate 24 holds a certain amount of cold water below the ice-making evaporator 22. When the cooling medium is introduced into the ice-making evaporator 22, the ice-making evaporator 22 uses the cold water in the support plate 24 to make ice. After ice making for a period of time, the ice-making evaporator 22 produces ice of a certain thickness. The drive motor 25 is then started to flip the support plate 24 to pour out the cold water and stop ice making.

[0057] In some embodiments, the ice-making module includes a water-drawing pipe 26 and a water-drawing pump 27. One end of the water-drawing pipe 26 is connected to the bottom of the refrigerator 21, and the other end of the water-drawing pipe 26 is connected to the support plate 24. The water-drawing pump 27 is disposed on the water-drawing pipe 26.

[0058] Specifically, one end of the water suction pipe 26 is connected to the bottom of the refrigerator 21 to extract cold water from the bottom of the refrigerator 21, and the other end of the water suction pipe 26 is connected to the support plate 24 so that the extracted cold water can be reinjected into the support plate 24. The water pump 27 is installed on the water suction pipe 26 to provide the power required for water pumping. After starting the drive motor 25 to flip the support plate 24 to pour out the cold water and stop ice making, if it is necessary to continue ice making, start the drive motor 25 to flip the support plate 24 back to the starting position, start the water pump 27 to pump the water from the bottom of the refrigerator 21 onto the support plate 24, and make ice through the ice evaporator 22.

[0059] The water pump 27 can be installed in the middle of the water pump pipe 26 or near one end of the refrigerator 21 to provide better pumping power. During the ice-making process, as the cold water on the support tray 24 gradually freezes into ice in the ice evaporator 22, a certain amount of unfrozen cold water or a mixture of melted ice and water will accumulate at the bottom of the refrigerator 21. At this time, the water pump 27 can be activated to extract the accumulated cold water through the water pump pipe 26 and re-inject it into the support tray 24 for ice making again.

[0060] In some embodiments, the pumping process can be automated through a control system or operated manually as needed. After pumping is completed, the pump 27 can automatically shut down or remain in standby mode, awaiting the next pumping demand.

[0061] In some embodiments, the ice-making module includes a first detection probe 28 and a second detection probe 29. The first detection probe 28 is located at the lower part of the ice-making refrigerator 21, and the second detection probe 29 is located at the upper part of the ice-making refrigerator 21.

[0062] Specifically, the first detection probe 28 is located in the lower part of the refrigerator 21 and is used to detect whether there is ice at the bottom or lower part of the refrigerator 21. The working principle of the first detection probe 28 can be achieved by infrared, ultrasonic, capacitive sensing or mechanical contact, etc.

[0063] The second detection probe 29 is located at the upper part of the refrigerator 21 and is used to detect whether there is ice on the top or upper part of the refrigerator 21. Its working principle is similar to that of the first detection probe 28, but the installation position and function are different. The second detection probe 29 is used to detect whether the refrigerator 21 is full of ice, while the first detection probe 28 detects whether the refrigerator 21 is empty of ice.

[0064] In practical applications, the detection signals from the first detection probe 28 and the second detection probe 29 can be transmitted to the control system via a signal transmission line or wireless communication. Based on the received detection signals, the control system determines whether the ice maker 21 is empty or full, and accordingly controls the subsequent operations of the ice-making module, such as continuing ice making, stopping ice making, or starting the defrosting program. When the ice maker 21 is determined to be full, the control system can output a control signal to stop ice making; when the ice maker 21 is determined to be empty, the control system outputs a control signal to continue ice making to replenish the ice. In some embodiments, an alarm or notification function can also be set to promptly notify the operator in case of abnormalities.

[0065] In some embodiments, the refrigeration system includes a defrosting module, which includes a second three-way pipe 51, a defrosting valve 52, and a defrosting pipe 53. The first interface of the second three-way pipe 51 is connected to the second end of the compressor 311, the second interface of the second three-way pipe 51 is connected to the first end of the condenser 312, the third interface of the second three-way pipe 51 is connected to the first end of the defrosting pipe 53, the second end of the defrosting pipe 53 is connected to the inlet of the ice evaporator 22, and the defrosting valve 52 is disposed on the defrosting pipe 53.

[0066] Specifically, the second tee pipe 51 is similar to the first tee pipe 14, and has three interfaces, which will not be described in detail here.

[0067] When the refrigeration system does not require ice making, the defrost valve 52 is opened. The high-temperature, high-pressure gas generated by the compressor 311 is not cooled by the condenser 312, but instead enters the ice-making evaporator 22 through the defrost inlet pipe 53 of the second three-way pipe 51. This causes the ice attached to the ice-making evaporator 22 to fall to the bottom of the refrigerator 21, thus achieving the defrosting function. When the refrigeration system needs to make ice or cool water, the defrost valve 52 is closed, and the high-temperature, high-pressure gas generated by the compressor 311 is introduced into the condenser 312 for cooling.

[0068] Secondly, this utility model embodiment also provides a water dispenser, including a refrigeration system.

[0069] Specifically, in addition to the refrigeration system, the water dispenser in this embodiment also includes a heating system, a filtration system, and a control system. The heating system includes heating elements (a hot water tank and a heater, etc.). When the user needs hot water, the heater is activated to heat the water in the tank to a preset temperature, providing warm drinking water. The filtration system includes multi-stage filtration devices, such as activated carbon filters, ultrafiltration membranes, or reverse osmosis membranes. These filtration devices remove impurities, odors, residual chlorine, and harmful substances such as heavy metals from the water, providing safe drinking water. The control system typically includes a microprocessor, sensors, a display screen, and buttons. The user can select the desired drinking water temperature via buttons or a touchscreen. The control system activates the corresponding refrigeration or heating system based on the user's selection and monitors water temperature changes through sensors to ensure the water temperature remains stable within the preset range. Of course, in addition to the systems mentioned above, the water dispenser in this embodiment can also be equipped with other systems to meet the user's actual needs.

[0070] When the water dispenser is first turned on, the filtration system starts working. Filtered purified water enters the hot water tank and is heated to boiling by the heater to produce boiling water. Then, the boiling water in the hot water tank flows into the inner tube of the heat exchange pipe, while simultaneously, purified water flows from the outer tube of the heat exchange pipe to replenish the hot water flowing out of the hot water tank. During this process, hot and cold water exchange heat, lowering the boiling water temperature to the required warm water. Then, the warm water enters the cold water tank, the compressor starts, and the subsequent cooling or ice-making operation begins.
