Description

Technical Field

[0001] The utility model relates to the technical field of automatic beverage machines, in particular to an ice-making device with heat dissipation and heat insulation. Background Art

[0002] In an automatic beverage machine, in order to quickly provide users with cold drinks at a lower temperature, ice cubes need to be added to the produced drinks to achieve rapid cooling. In existing ice-making machines, refrigeration and ice cubes are often completed by refrigerants. During the refrigeration process, the low-temperature and low-pressure gaseous refrigerant is compressed by the compressor and converted into a high-temperature and high-pressure gaseous refrigerant; then the high-temperature and high-pressure gaseous refrigerant enters the condenser for condensation and becomes a high-pressure liquid refrigerant; the liquid refrigerant is converted into a low-pressure liquid refrigerant through the throttling effect of the expansion valve, and then flows into the evaporator; the low-pressure liquid refrigerant undergoes a heat exchange with the drinking water in the evaporator without direct contact, and the low-pressure liquid refrigerant evaporates into a low-temperature and low-pressure gaseous refrigerant, while absorbing environmental heat, causing the temperature of the drinking water to drop and turn into ice cubes, and then the ice cubes enter the storage structure with the water flow, while the low-temperature and low-pressure gaseous refrigerant returns to the compressor to complete the refrigeration cycle. Although the existing ice-making mechanism can effectively produce ice cubes, the internal structure of the automatic beverage machine is relatively compact. During the refrigeration process, the two main devices, the condenser and the compressor, will continuously generate heat during the refrigeration process, which will have an adverse effect on the ice generation process in the evaporator and easily cause the ice cubes to melt. In addition, in the closed internal environment of the automatic beverage machine, if the heat generated by the condenser and the compressor cannot be discharged in time, the overall operating efficiency of the automatic beverage machine will be reduced, and it is easy to trigger the overheat protection and shut down, which will easily cause a decrease in ice making efficiency and poor ice storage effect.

[0028] In this embodiment, the heat-dissipating and heat-insulating ice-making device 10 is arranged inside the automatic beverage machine, and the automatic beverage machine is a fully enclosed structure, and the side wall of the heat-dissipating and heat-insulating ice-making device 10 is attached to the inner side wall of the automatic beverage machine, and the heat-dissipating fan 800 arranged on the heat-dissipating cavity 600 is also connected to the outside of the automatic beverage machine to discharge the hot air in the heat-dissipating cavity 600 in time. The heat-dissipating cavity 600 is actually a space surrounded by multiple rigid plate structures, and the compressor 100 and the condenser 200 are both arranged in the heat-dissipating cavity 600, and the compressor 100 and the condenser 200 are fixedly connected to the inner wall of the heat-dissipating cavity 600, and can be connected to one of the inner walls of the heat-dissipating cavity 600 close to the outside of the automatic beverage machine, so as to achieve a good heat dissipation effect. The heat insulation board 700 is a plate-shaped structure that can achieve a heat insulation function. The heat insulation board 700 is vertically arranged in the heat dissipation and heat insulation ice-making device 10, and one end surface thereof is attached to one side of the heat dissipation cavity 600, and the other end surface faces the screw evaporator 400, the ice storage cylinder 500 and the expansion valve 300 located outside the heat dissipation cavity 600. The heat insulation board 700 can also directly serve as one of the side walls of the heat dissipation cavity 600.

[0029] The evaporation channel 410 in the screw evaporator 400, the compressor 100, the condenser 200 and the expansion valve 300 are connected by pipelines, and the evaporation channel 410, the compressor 100, the condenser 200 and the expansion valve 300 are used to transmit gaseous or liquid refrigerants through pipelines. In a complete refrigeration process, the low-temperature and low-pressure gaseous refrigerant enters the compressor 100 through the air inlet end of the compressor 100, is compressed by the compressor 100, and is converted into a high-temperature and high-pressure gaseous refrigerant, while releasing heat; then the high-temperature and high-pressure gaseous refrigerant is discharged from the compressor 100 through the air outlet end of the compressor 100, enters the condenser 200 through the air inlet end of the condenser 200 to be condensed, and becomes a high-pressure liquid refrigerant, while releasing heat; then the high-pressure liquid refrigerant is discharged from the condenser 200 through the liquid outlet end of the condenser 200, flows into the liquid inlet end of the expansion valve 300, and becomes a high-pressure liquid refrigerant through the throttling effect of the expansion valve 300. It is a low-pressure liquid refrigerant, and absorbs heat at the same time, then flows out of the expansion valve 300 through the liquid outlet of the expansion valve 300, and flows into the liquid inlet of the evaporation channel 410 in the screw evaporator 400; the low-pressure liquid refrigerant exchanges heat without direct contact with the drinking water inside the ice-making channel 420 in the evaporation channel 410, and the low-pressure liquid refrigerant evaporates into a low-temperature and low-pressure gaseous refrigerant, and absorbs environmental heat at the same time, so that the temperature of the drinking water drops and gradually turns into ice cubes, and then the ice cubes enter the ice storage cylinder 500 along with the water flow of the ice-making channel 420, and the low-temperature and low-pressure gaseous refrigerant returns to the compressor 100 to complete the refrigeration cycle. The ice-making channel 420 and the evaporation channel 410 are both spiral structures, and the outer walls of the ice-making channel 420 and the evaporation channel 410 fit each other. The water inlet of the ice making channel 420 is located below the ice outlet. The water inlet can absorb water and transfer it upward through the spiral structure. During the transfer process, the drinking water is gradually cooled by the refrigerant in the evaporation channel 410 and becomes ice cubes. Subsequently, the water flow continuously flowing into the ice making channel 420 from the lower water inlet pushes the ice cubes out of the ice outlet and falls into the ice storage cylinder 500. The ice storage cylinder 500 is provided with an ice cube outlet for the ice cubes to fall from the ice storage cylinder 500 into the beverage. In this process, the compressor 100 and the condenser 200 generate a lot of heat, causing the surrounding environment temperature to rise. Since the compressor 100 and the condenser 200 are both located in the heat dissipation cavity 600, the heat dissipation fan 800 can effectively discharge heat to ensure the normal operation of the compressor 100 and the condenser 200; at the same time, the heat insulation plate 700 can prevent heat from being transmitted toward the screw evaporator 400, the expansion valve 300 and the ice storage barrel 500. Therefore, the ambient temperature of the screw evaporator 400, the expansion valve 300 and the ice storage barrel 500 can always be maintained at a low level, and then, the screw evaporator 400 can perform refrigeration normally, and the throttling effect of the expansion valve 300 can also be stably exerted, and the ice cubes inside the ice storage barrel 500 are not easy to melt, and the overall ice-making efficiency is improved.

[0030] Optional, such as Figure 1 As shown, the condenser 200 is arranged above the compressor 100, and the condenser 200 is fixedly connected to the inner side wall of the heat dissipation cavity 600 opposite to the heat insulation board 700. The condenser 200 and the compressor 100 are connected through a pipeline. Since the condenser 200 is located above the compressor 100, the high-temperature and high-pressure gaseous refrigerant can freely rise along the pipeline and enter the condenser 200 after gushing out of the compressor 100, thereby ensuring the flow efficiency of the refrigerant and avoiding the setting of unnecessary air guide equipment. At the same time, since the condenser 200 fits the inner side wall of the heat dissipation cavity 600, the heat of the condenser 200 can also be discharged faster through the inner side wall of the heat dissipation cavity 600. Among them, the inner side wall is the inner side wall opposite to the heat insulation board 700.

[0031] In one embodiment, if Figure 2 As shown, the heat insulation board 700 includes a heat insulation board 700 body and heat insulation cotton 720; the heat insulation cotton 720 is fixedly connected to the heat insulation board 700 body, and the heat insulation cotton 720 covers both sides of the heat insulation board 700 body.

[0032] In this embodiment, the main body of the heat insulation board 700 is a plate-shaped structure made of metal material, and both side end surfaces of the main body of the heat insulation board 700 are wrapped with heat insulation cotton 720, and the heat insulation cotton 720 can be made of materials with heat insulation function such as foam cotton. Furthermore, the heat in the heat dissipation cavity 600 can be effectively blocked by the heat insulation cotton 720 to prevent it from continuing to conduct toward the side of the heat insulation board 700 toward the screw evaporator 400. Among them, the heat insulation board 700 is one of the end surfaces enclosed to form the heat dissipation cavity 600, and the heat in the heat dissipation cavity 600 can be directly blocked by the heat insulation board 700.

[0033] In one embodiment, if Figure 1 As shown, the heat dissipating and insulating ice-making device 10 also includes a filter cover tube 900; the filter cover tube 900 is fixedly connected to the side of the insulation board 700 facing the compressor 100; the air outlet end of the evaporation channel 410 is connected to the air inlet end of the compressor 100 through the filter cover tube 900; the filter cover tube 900 is used to filter impurities in the refrigerant.

[0034] In this embodiment, the filter cover tube 900 includes an outer cover tube and a filter element. The filter element is wrapped in the outer cover tube, and the two ends of the outer cover tube are respectively connected to the outlet end of the evaporation channel 410 and the inlet end of the compressor 100. Then, when the gaseous refrigerant flows back from the evaporation channel 410 to the compressor 100, the refrigerant will pass through the filter element in the filter cover tube 900, so that the impurities are absorbed by the filter element, thereby ensuring the purity and refrigeration effect of the refrigerant. The filter cover tube 900 can be set as a tubular structure with a larger inner diameter, and its inner diameter is larger than the pipeline connecting the screw evaporator 400 and the compressor 100. Then, the refrigerant can be fully filtered and purified in the filter cover tube 900 with a larger inner diameter. At the same time, the filter cover tube 900 is also arranged inside the heat dissipation cavity 600 to prevent the refrigerant gradually heating up in the reflux from interfering with the normal operation of the screw evaporator 400.

[0036] In this embodiment, the filter cover tube 900 is fixedly connected to the heat insulation board 700 in the vertical direction, and the first end of the filter cover tube 900 is located below the second end. Then, after the gaseous refrigerant flows out from the gas outlet end of the evaporation channel 410, it reaches the first end of the filter cover tube 900 through the first gas pipe 910, and then the gaseous refrigerant passes through the filter element inside the filter cover tube 900 from bottom to top, eliminating the pressurization structure, so that the gaseous refrigerant flows and filters naturally, and finally flows back to the compressor 100 through the second gas pipe 920 to be re-pressurized.

[0037] In one embodiment, if Figure 1 As shown, the heat-dissipating and heat-insulating ice-making device 10 also includes a solenoid valve 1000; the solenoid valve 1000 is fixedly connected to the side of the insulation board 700 facing the compressor 100; the liquid outlet end of the condenser 200 is connected to the liquid inlet end of the expansion valve 300 through the solenoid valve 1000; the liquid outlet end of the expansion valve 300 is connected to the liquid inlet end of the evaporation channel 410; the solenoid valve 1000 is used to control the on-off of the flow path of the refrigerant.

[0038] In this embodiment, the solenoid valve 1000 can be a one-way solenoid valve 1000. When the solenoid valve 1000 is turned on, the liquid refrigerant can pass through the solenoid valve 1000 in a single direction, from the condenser 200 to the expansion valve 300 and be reduced in pressure by the expansion valve 300 to a low-pressure liquid refrigerant, and then enter the evaporation channel 410 for refrigeration. During operation, the opening and closing of the refrigerant flow path can be realized by controlling the opening and closing of the solenoid valve 1000.

[0039] In one embodiment, if Figure 1 As shown, the heat-dissipating and heat-insulating ice-making device 10 also includes a first infusion tube 1010 and a second infusion tube 1020; the two ends of the first infusion tube 1010 are respectively connected to the liquid outlet end of the condenser 200 and the first end of the solenoid valve 1000; the second end of the solenoid valve 1000 is connected to the liquid inlet end of the expansion valve 300 through the second infusion tube 1020; the second end of the solenoid valve 1000 is located below the first end.

[0040] In this embodiment, the second end of the solenoid valve 1000 is located below the first end, and the liquid refrigerant enters the first end of the solenoid valve 1000 through the first liquid infusion pipe 1010, and then reaches the second end of the solenoid valve 1000 along the gravity direction, and reaches the expansion valve 300 through the second liquid infusion pipe 1020. Through this arrangement, the one-way transmission of the liquid refrigerant can be effectively achieved to prevent the backflow of the refrigerant.

[0042] In this embodiment, the liquid delivery pipeline 1100 is the pipeline through which the liquid refrigerant flows from the condenser 200 to the expansion valve 300, and the gas delivery pipeline 1200 is the pipeline through which the gaseous refrigerant flows from the screw evaporator 400 to the compressor 100. Two through holes are provided on the heat insulation board 700, and the first and second wire sheaths 730 and 740 are respectively installed in the two through holes. The first and second wire sheaths 730 and 740 are both made of heat insulating materials such as silica gel, and through holes are provided on the first and second wire sheaths 730 and 740. The liquid infusion pipeline 1100 passes through the through hole opened on the first wire sheath 730, and the two ends of the liquid infusion pipeline 1100 are respectively located on both sides of the insulation board 700 and are respectively connected to the condenser 200 and the expansion valve 300; the gas delivery pipeline 1200 passes through the through hole opened on the second wire sheath 740, and the two ends of the gas delivery pipeline 1200 are respectively located on both sides of the insulation board 700 and are respectively connected to the evaporation channel 410 and the compressor 100.

[0043] In one embodiment, if Figure 4 As shown, the condenser 200 includes a plurality of condensing tubes 210 arranged in a horizontal direction; the cooling fan 800 includes a first fan 810 and a second fan 820 arranged in parallel; the rotation axis of the first fan 810 and the rotation axis of the second fan 820 are perpendicular to the extension axis of each of the condensing tubes 210, and the first fan 810 and the second fan 820 are directly opposite to each of the condensing tubes 210.

[0044] In this embodiment, a plurality of condensing tubes 210 are arranged in parallel, and each condensing tube 210 is arranged in the horizontal direction. The condensing tubes 210 are connected by bending tubes with a bending angle of 180 degrees to form a plurality of S-shaped swirling condensation structures. The gaseous refrigerant enters the condenser 200 from one end of one of the condensing tubes 210 located at the top, and then the liquid refrigerant flows out of the condenser 200 from one end of the condensing tube 210 located at the bottom. In this process, the gaseous refrigerant liquefies and releases a large amount of heat, and the first fan 810 and the second fan 820 are facing each condensing tube 210 for air cooling and heat dissipation, so as to efficiently discharge the heat generated by each condensing tube 210 out of the heat dissipation cavity 600 in time, and ensure the normal operation of the condenser 200.

[0046] In this embodiment, the secondary water tank 1300 is used to transfer drinking water and to supply water to the water inlet of the ice-making channel 420 as a water source. The secondary water tank 1300 includes a water inlet and a water outlet, and the water inlet is connected to the water inlet pump 1400. The water inlet pump 1400 can actively pump drinking water into the secondary water tank 1300 and store it. Subsequently, the ice-making channel 420 can autonomously pump drinking water from the secondary water tank 1300, thereby improving the supply efficiency of drinking water to the ice-making channel 420. The secondary water tank 1300 is also arranged on the side of the insulation board 700 facing the screw evaporator 400 to ensure a lower temperature of the drinking water and improve the ice-making efficiency.

[0047] In one embodiment, if Figure 5 As shown, the side wall of the ice storage barrel 500 is provided with an openable and closable ice cube outlet 510; the side wall of the ice storage barrel 500 is detachably connected with an ice cube flow channel 520; one end of the ice cube flow channel 520 is directly opposite to the ice cube outlet 510; the ice cube flow channel 520 is used to guide the ice cubes in the ice storage barrel 500 to fall.

[0048] In this embodiment, the ice cube outlet 510 can be set to an openable structure, and the openable structure can be opened or closed under the control of an additionally connected control unit. When the ice cube outlet 510 is controlled to be opened, the ice cubes stored in the ice storage barrel 500 fall out of the ice storage barrel 500 through the ice cube outlet 510. When the number of ice cubes falling reaches the requirement, the control unit controls the ice cube outlet 510 to be closed to stop the ice cubes from falling. The ice cube flow channel 520 is a hollow pipe structure, which is made of food-grade materials, and the ice cube flow channel 520 can be arranged in a vertical direction, with its top facing the ice cube outlet 510 and its bottom facing the bottom of the ice storage barrel 500. After the ice cubes fall into the ice cube flow channel 520, the ice cube flow channel 520 can guide the ice cubes to fall into the container placed in advance under the ice storage barrel 500, ensuring safety and hygiene while ensuring that the ice cubes fall accurately.

[0049] It can be seen that based on the above structure and its connection method, the heat-dissipating and heat-insulating ice-making device provided by the embodiment of the utility model can achieve rapid heat dissipation of the heat generated by the condenser and the compressor during the ice-making process by arranging the condenser and the compressor in the heat-dissipating cavity, using a heat-dissipating fan to air-cool the condenser that generates more heat, and separating the inside and outside of the heat-dissipating cavity by a heat-insulating plate, and arranging the screw evaporator and the ice storage cylinder on the other side of the heat-insulating plate, thereby ensuring the working efficiency of the condenser and the compressor. At the same time, the heat-insulating plate effectively prevents excessive heat from being transferred to the screw evaporator, ensuring that the evaporator operates in a low-temperature environment formed by itself, ensuring that the refrigerant in the evaporation channel inside the screw evaporator efficiently cools the water source in the ice-making channel, thereby efficiently producing ice cubes and reducing the melting rate of ice cubes in the ice storage cylinder.

[0050] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
