Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] Combination Figures 1 to 6 According to an embodiment of the present invention, a refrigeration device 100 includes a housing 10 and a refrigeration unit. The housing 10 contains a first hopper 11 and a second hopper 12. The refrigeration unit includes a condenser 23, a first evaporator 21, and a second evaporator 22. The condenser 23 is connected to the first evaporator 21 and the second evaporator 22. The first evaporator 21 is configured to refrigerate the first hopper 11 using a refrigerant phase change, and the second evaporator 22 is configured to refrigerate the second hopper 12 using a refrigerant phase change. Specifically, the first hopper 11 and the second hopper 12 can be used to make different beverages, such as beverages of the same type but different flavors. By integrating two hoppers into the refrigeration device 100, the functionality and practicality of the refrigeration device can be improved.

[0020] Furthermore, the first evaporator 21 and the second evaporator 22 can respectively cool the first silo 11 and the second silo 12, thereby improving the cooling effect of the first silo 11 and the second silo 12 and improving the quality of the processed materials. For example, the first evaporator 21 can be located inside the first silo 11, allowing the material in the first silo 11 to directly contact the first evaporator 21, and the second evaporator 22 can be located inside the second silo 12, allowing the material in the second silo 12 to directly contact the second evaporator 22, thus improving the cooling effect.

[0021] Furthermore, the refrigeration equipment 100 also includes a control mechanism configured to control the flow of refrigerant through the first evaporator 21 and / or the second evaporator 22. Thus, by providing the control mechanism, the first evaporator 21 and the second evaporator 22 can be controlled separately, thereby enabling separate control of material production in the first hopper 11 and the second hopper 12. For example, one of the first hopper 11 or the second hopper 12 can be controlled to operate while the other remains inactive.

[0022] According to the refrigeration equipment 100 of this utility model embodiment, by setting a control mechanism, the refrigeration of the first silo 11 and the second silo 12 can be controlled separately, which helps to improve the flexibility and functionality of the refrigeration equipment 100 during use and brings convenience to users.

[0023] Combination Figure 2In some embodiments of this utility model, the refrigeration device includes a compressor 24, the output end of the compressor 24 is connected to the input end of the condenser 23, the first evaporator 21 is connected between the output end of the condenser 23 and the input end of the compressor 24, and the second evaporator 22 is connected between the output end of the condenser 23 and the input end of the compressor 24. Thus, a control mechanism is provided between the condenser 23 and the first evaporator 21 and the second evaporator 22. The control mechanism can be openably and closeably connected to the output end of the condenser 23 and the input ends of the first evaporator 21 and / or the second evaporator 22. Specifically, when the control mechanism connects the condenser 23 and the first evaporator 21, the refrigerant can flow from the condenser 23 to the first evaporator 21, so that the first evaporator 21 can cool the first silo 11; when the control mechanism connects the condenser 23 and the second evaporator 22, the refrigerant can flow from the condenser 23 to the second evaporator 22, so that the second evaporator 22 can cool the second silo 12; when the control mechanism simultaneously connects the condenser 23 to the first evaporator 21 and the second evaporator 22, the refrigerant can flow from the condenser 23 to the first evaporator 21, and the refrigerant can also flow from the condenser 23 to the second evaporator 22, so that the first evaporator 21 can cool the first silo 11, and the second evaporator 22 can cool the second silo 12.

[0024] Combination Figure 2 In some embodiments of this utility model, the first evaporator 21 and the second evaporator 22 are connected in parallel to the condenser 23. The control mechanism is configured to control the flow rate between the condenser 23 and the first evaporator 21, as well as between the condenser 23 and the second evaporator 22. This allows for independent operation and control of the first evaporator 21 and the second evaporator 22, thereby improving the functionality of the refrigeration equipment 100. Specifically, the outlet of the condenser 23 can be connected to the inlet of the first evaporator 21 and the inlet of the second evaporator 22, respectively, so that the refrigerant flowing out of the condenser 23 can selectively flow into the first evaporator 21 or the second evaporator 22, or simultaneously into both, under the control of the control mechanism. Furthermore, the control mechanism can also control the flow rate of refrigerant from the condenser 23 into the first evaporator 21 and the second evaporator 22, thereby controlling the cooling effect of the first evaporator 21 and the second evaporator 22.

[0025] Specifically, the control mechanism controls whether the refrigerant flows through the first evaporator 21 and the second evaporator 22, and also controls the flow rate of the refrigerant through the first evaporator 21 and the second evaporator 22. When the flow rates of the refrigerant through the first evaporator 21 and the second evaporator 22 are different, the cooling effects of the first evaporator 21 and the second evaporator 22 are different. This allows the first evaporator 11 and the second evaporator 12 to be used to make beverages at different temperatures, thereby further improving the functionality and practicality of the refrigeration equipment 100. For example, the first evaporator 11 can be used to make smoothies or ice cream, while the second evaporator 12 can be used to make cold drinks.

[0026] For example, the control mechanism can control the flow rate of refrigerant through the first evaporator 21 and the second evaporator 22. For instance, when the refrigerant flow rate through the first evaporator 21 is greater than the refrigerant flow rate through the second evaporator 22, the cooling temperature of the first hopper 11 can be lower than the cooling temperature of the second hopper 12. The first hopper 11 can be used to make smoothies or ice cream at a lower temperature, and the second hopper 12 can be used to make cold drinks.

[0027] Combination Figure 2 In some embodiments of this utility model, the control mechanism includes a first solenoid valve 31 and a second solenoid valve 32. The first solenoid valve 31 is connected between the condenser 23 and the first evaporator 21 and can be used to connect or disconnect the condenser 23 and the first evaporator 21 to control whether the refrigerant flows into the first evaporator 21 or to control the flow rate of the refrigerant into the first evaporator 21. The second solenoid valve 32 is connected between the condenser 23 and the second evaporator 22 and can be used to connect or disconnect the condenser 23 and the second evaporator 22 to control whether the refrigerant flows into the second evaporator 22 or to control the flow rate of the refrigerant into the first evaporator 21.

[0028] Optionally, the first solenoid valve 31 and the second solenoid valve 32 can be solenoid valves for on / off control. When the cooling temperatures of the first evaporator 21 and the second evaporator 22 are different, the flow rate of refrigerant into the first evaporator 21 and the second evaporator 22 can be controlled by controlling the on-time of the first solenoid valve 31 and the second solenoid valve 32. For example, when the cooling temperature of the first evaporator 21 is lower than that of the second evaporator 22, the first solenoid valve 31 and the second solenoid valve 32 can be opened simultaneously, allowing the refrigerant to flow into the first evaporator 21 and the second evaporator 22 respectively. The second hopper 12 reaches the predetermined cooling temperature first, the second solenoid valve 32 disconnects the condenser 23 from the second evaporator 22, and the first solenoid valve 31 continues to maintain the flow of refrigerant between the condenser 23 and the first evaporator 21 until the first hopper 11 reaches the predetermined cooling temperature, at which point the first solenoid valve 31 disconnects the condenser 23 from the first evaporator 21. Once one of the first hopper 11 and the second hopper 12 reaches the predetermined cooling temperature, an evaporator can operate at a lower power or stop operating, thereby reducing the workload of the compressor and improving energy efficiency.

[0029] Optionally, the first solenoid valve 31 and the second solenoid valve 32 can be proportional regulating solenoid valves capable of adjusting flow rates, so that the first solenoid valve 31 and the second solenoid valve 32 can adjust the refrigerant flow rate according to different refrigeration temperatures. For example, when the refrigeration temperature of the first hopper 11 is lower than that of the second hopper 12, both the first solenoid valve 31 and the second solenoid valve 32 need to be opened, and the refrigerant flow rate through the first solenoid valve 31 can be greater than the refrigerant flow rate through the second solenoid valve 32. For instance, the first solenoid valve 31 and the second solenoid valve 32 can be adjusted to a predetermined state according to a preset temperature, so that a predetermined flow rate of refrigerant flows into the evaporator.

[0030] Optionally, the first hopper 11 and the second hopper 12 can be equipped with temperature sensors for detecting the temperature inside the hoppers. The refrigeration equipment 100 can be equipped with a controller 90. The temperature sensors can transmit signals with the control mechanism through the controller 90 to achieve temperature control inside the hoppers. Specifically, the user can set the temperature of the first hopper 11 and the second hopper 12 through the controller 90, for example, setting the temperature of the first hopper 11 and the second hopper 12 to the same or different temperatures according to actual usage needs. The control mechanism can transmit signals with the controller 90 and control the operation of the first solenoid valve 31 and the second solenoid valve 32 according to the signals from the controller 90 to cool the first hopper 11 and the second hopper 12. The temperature sensors can feed back the temperature of the first hopper 11 and the second hopper 12 to the control mechanism. For example, based on the temperature information from the temperature sensors, the control mechanism can continue to open the first solenoid valve 31 and the second solenoid valve 32 or selectively close the first solenoid valve 31 and the second solenoid valve 32 to achieve the operation of the control mechanism.

[0031] Combination Figure 2, Figure 5 and Figure 6 In some embodiments of this utility model, the control mechanism includes a first support member 41 and a second support member 42. The first support member 41 is connected to the housing 10, and the first solenoid valve 31 is disposed on the first support member 41. The second support member 42 is connected to the housing 10, and the second solenoid valve 32 is disposed on the second support member 42. That is, the first solenoid valve 31 can be fixed inside the housing 10 by the first support member 41, and the second solenoid valve 32 can be fixed inside the housing 10 by the second support member 42, which can improve the stability of the first solenoid valve 31 and the second solenoid valve 32 after assembly.

[0032] Combination Figure 5 Specifically, in some embodiments of this utility model, the first support member 41 includes a first plate portion 411, a second plate portion 412, a third plate portion 413, and a fourth plate portion 414. The first plate portion 411 is connected to the housing 10. One side of the second plate portion 412 is connected to the first plate portion 411, and the other side is connected to the third plate portion 413. The third plate portion 413 is connected to the fourth plate portion 414, forming an accommodating space. The first solenoid valve 31 is supported on the fourth plate portion 414. The first plate portion 411, the second plate portion 412, the third plate portion 413, and the fourth plate portion 414 are provided with included angles between each pair, so that the direction of the end of the first support member 41 connected to the housing 10 and the direction of the position where the first support member 41 supports the first solenoid valve 31 can be different, realizing the direction conversion. This allows the first support member 41 to connect to the housing 10 and the first solenoid valve 31 respectively, and the position of the first solenoid valve 31 can be flexibly arranged, which is beneficial for spatial arrangement.

[0033] Combination Figure 6 The second support member 42 includes a fifth plate portion 425, a sixth plate portion 426, and a seventh plate portion 427. The fifth plate portion 425 is connected to the housing 10. One end of the sixth plate portion 426 is connected to the fifth plate portion 425, and the other end is connected to the seventh plate portion 427, forming an accommodating space. The second solenoid valve 32 is supported on the seventh plate portion 427. The fifth plate portion 425, the sixth plate portion 426, and the seventh plate portion 427 are provided with included angles between each pair, so that the direction of the end of the second support member 42 connected to the housing 10 and the direction of the second solenoid valve 32 supported by the second support member 42 can be different, realizing the conversion of direction. This allows the second support member 42 to be connected to the housing 10 and the second solenoid valve 32 respectively, and the position of the second solenoid valve 32 can be flexibly arranged, which is beneficial for space arrangement.

[0034] The included angle between the two plates can be ninety degrees, a right angle, or the two plates can be perpendicular to each other, depending on the structure inside the housing 10 and the first support member 41 and the second support member 42 according to some embodiments of the present invention.

[0035] Furthermore, combined Figure 2The housing 10 contains a support 40. The first hopper 11 and the second hopper 12 are arranged side-by-side on the support 40. The support 40 creates a accommodating space within the housing 10, where the compressor 24 is housed. Specifically, the support 40 provides support within the housing 10. The upper end of the support 40 supports the first hopper 11 and the second hopper 12, while the lower end connects to the bottom of the housing 10. A accommodating space is created between the bottom of the housing 10 and the upper end of the support 40 to house the compressor 24 via piping, facilitating spatial arrangement and improving the structural stability of the refrigeration equipment 100 after assembly. The control mechanism can be arranged within this accommodating space, allowing it to be positioned between the condenser 23 at the bottom of the refrigeration unit and the first evaporator 21 and the second evaporator 22 at the top.

[0036] Specifically, a bracket may be provided at the upper end of the support 40, and the first hopper 11 and the first evaporator 21 for cooling the first hopper 11 may be provided on the bracket, as may the second hopper 12 and the second evaporator 22 for cooling the second hopper 12.

[0037] Furthermore, one end of the first support member 41 or the first plate portion 411 is connected to the bracket 40, and the other end supports the first solenoid valve 31; one end of the second support member 42 or the fourth plate portion 414 is connected to the bracket 40, and the other end supports the second solenoid valve 32, thereby connecting the first solenoid valve 31 and the second solenoid valve 32 to the bracket 40.

[0038] Combination Figure 2 In some embodiments of this utility model, the control mechanism includes a main channel 330, a first branch 310 and a second branch 320. The inlet of the main channel 330 is connected to the condenser 23, and the outlet of the main channel 330 is connected to the inlet of the first branch 310 and the second branch 320. The outlet of the first branch 310 is connected to the first evaporator 21, and the outlet of the second branch 320 is connected to the second evaporator 22. A first solenoid valve 31 is located in the first branch 310, and a second solenoid valve 32 is located in the second branch 320.

[0039] Specifically, the first solenoid valve 31 can be located near the inlet of the first branch 310, in the middle of the first branch 310, or near the outlet of the first branch 310. The second solenoid valve 32 can be located near the inlet of the second branch 320, in the middle of the second branch 320, or near the outlet of the second branch 320.

[0040] For example, when the first solenoid valve 31 and the second solenoid valve 32 are located near the inlet end of the first branch 310 and the second branch 320, one end of the first solenoid valve 31 can be connected to the main channel 330 and the other end can be connected to the inlet of the first branch 310, and one end of the second solenoid valve 32 can be connected to the main channel 330 and the other end can be connected to the inlet of the second branch 320.

[0041] When the first solenoid valve 31 and the second solenoid valve 32 are located in the middle position between the first branch 310 and the second branch 320, the refrigerant flowing into the first branch 310 needs to pass through the first solenoid valve 31 before flowing out of the outlet of the first branch 310. This allows the first solenoid valve 31 to control the on / off state and flow rate of the refrigerant entering the first branch 310. Similarly, the refrigerant flowing into the second branch 320 needs to pass through the second solenoid valve 32 before flowing out of the outlet of the second branch 320. This allows the second solenoid valve 32 to control the on / off state and flow rate of the refrigerant entering the second branch 320. Therefore, the condenser 23 can be connected to the main flow channel 330, through which the refrigerant is transferred to the first branch 310 and the second branch 320. The refrigerant is supplied to the first evaporator 21 from the first branch 310 and to the second evaporator 22 from the second branch 320. This allows for a parallel connection between the condenser 23, the first evaporator 21, and the second evaporator 22, and the structure is simple and easy to construct.

[0042] In some embodiments of this invention, the refrigeration device includes a first throttling element 51. The inlet of the first throttling element 51 is connected to the outlet of the condenser 23, and the outlet of the first throttling element 51 is connected to the inlet of the first branch 310 and the inlet of the second branch 320, respectively. Specifically, the high-pressure refrigerant flowing out of the condenser 23 experiences a sudden pressure drop after passing through the first throttling element 51, becoming a low-temperature, low-pressure state. This low-temperature, low-pressure refrigerant then flows into the evaporator under the control of a solenoid valve. In the evaporator, the liquid refrigerant evaporates and absorbs a large amount of heat, thereby lowering the temperature of the liquid in the feed hopper, which is in close contact with the evaporator, thus completing the production of cold drinks, smoothies, or ice cream. In other words, the throttling element can be located between the condenser 23 and the control mechanism.

[0043] Combination Figure 2In some other embodiments of this utility model, the throttling element can also be located between the control mechanism and the first evaporator 21 and the second evaporator 22. Specifically, the refrigeration device includes a first throttling element 51 and a second throttling element 52. One end of the first throttling element 51 is connected to the outlet of the first branch 310, and the other end is connected to the first evaporator 21; one end of the second throttling element 52 is connected to the outlet of the second branch 320, and the other end is connected to the second evaporator 22. In this way, the control mechanism can be located between the throttling element and the condenser 23 to control whether the refrigerant flows into the throttling element. After the refrigerant enters the throttling element, it undergoes a phase change and then enters the evaporator, which helps to improve the stability of the refrigeration device and improve the refrigeration effect.

[0044] Alternatively, the throttling element can be a capillary tube or an expansion valve.

[0045] Combination Figure 5 In some embodiments of this utility model, the first branch 310 includes a first pipe section 311 and a second pipe section 312. The inlet of the first pipe section 311 is connected to the main channel 330, and the outlet of the first pipe section 311 is connected to the first solenoid valve 31. The inlet of the second pipe section 312 is connected to the first solenoid valve 31, and the outlet of the second pipe section 312 is connected to the first throttling element 51. In this way, the first solenoid valve 31 can be installed on the first branch 310.

[0046] Combination Figure 6 The second branch 320 includes a third pipe section 323 and a fourth pipe section 324. The inlet of the third pipe section 323 is connected to the main channel 330, and the outlet of the third pipe section 323 is connected to the second solenoid valve 32. The inlet of the fourth pipe section 324 is connected to the second solenoid valve 32, and the outlet of the fourth pipe section 324 is connected to the second evaporator 22. The second solenoid valve 32 can be installed on the second branch 320. Specifically, both the first branch 310 and the second branch 320 are composed of two separate pipe sections. During assembly, the solenoid valve can be connected to each of the two pipe sections respectively, which facilitates assembly and maintenance, such as facilitating the replacement of the solenoid valve or the pipe section. The refrigerant in the main flow channel 330 first flows into the preceding or upstream pipe section (i.e., the first pipe section 311 or the third pipe section 323). When the solenoid valve is closed, the refrigerant cannot flow into the following or downstream pipe section (i.e., the second pipe section 312 or the fourth pipe section 324). When the solenoid valve is open, the refrigerant in the preceding or upstream pipe section can flow into the following or downstream pipe section through the solenoid valve, and then enter the throttling element and evaporator.

[0047] Furthermore, setting the first branch 310 and the second branch 320 as two pipe sections can also facilitate spatial arrangement. For example, the shape of the upstream and downstream pipe sections can be set according to the actual assembly space, reducing pipe bends and improving the structure.

[0048] The first pipe segment 311 of the first branch 310 and the third pipe segment 323 of the second branch 320 can achieve the effect of connecting the main channel 330 in parallel with the first solenoid valve 31 and the second solenoid valve 32.

[0049] In some embodiments of this utility model, the control mechanism includes a diverter 35, which has a first interface, a second interface, and a third interface. The first interface is connected to the outlet of the main channel 330, the second interface is connected to the inlet of the first branch 310, and the third interface is connected to the inlet of the second branch 320. The diverter 35 can connect the main channel 330 with the first branch 310 and the second branch 320, and its structure is simple and easy to maintain.

[0050] Optionally, the solenoid valve used to control the on / off state or flow rate of the main channel 330 and the branch can be directly connected to the diversion component 35, that is, the solenoid valve can be connected between the diversion component 35 and the branch. In conjunction with the foregoing, when the first solenoid valve 31 and the second solenoid valve 32 are located near the inlet end of the first branch 310 and the second branch 320, one end of the first solenoid valve 31 can be connected to the second interface of the diversion component 35 and the other end can be connected to the inlet of the first branch 310, and one end of the second solenoid valve 32 can be connected to the third interface of the diversion component 35 and the other end can be connected to the inlet of the second branch 320.

[0051] Combination Figure 1 and Figure 3 In some embodiments of this utility model, the refrigeration device 100 further includes a first switch 61 and a first piston valve 63. The first hopper 11 is provided with a first discharge port 601, and the first piston valve 63 is disposed within the first switch 61. The first switch 61 controls the first piston valve 63 to open or close the first discharge port 601. After being refrigerated, the liquid in the first hopper 11 can be discharged from the first discharge port 601. Specifically, the user can open and close the first discharge port 601 by controlling the first switch 61. The first piston valve 63 has a closed state and an open state. The first piston valve 63 is normally in the closed state to prevent material from flowing out of the first discharge port 601. When the user drives the first switch 61, the first piston valve 63, which is connected to the first switch 61, switches from the closed state to the open state, allowing material to flow out or be discharged from the first discharge port 601. The first switch 61 is also provided with a transmission component 64 and a reset component 65. The transmission component 64 abuts against the first piston valve 63 and can convert the user's action of rotating the first switch 61 into the movement of the first piston valve 63 in the up and down direction, thereby opening and closing the first discharge port 601. The reset component 65 has the force to drive the first piston valve 63 to remain in the closed state. When the force applied by the user to the first switch 61 disappears, the reset component 65 can drive the first piston valve 63 to automatically reset, that is, return from the open state to the closed state.

[0052] Similarly, the refrigeration equipment 100 includes a second switching element 62 and a second piston valve. The second hopper 12 has a second discharge port. The second piston valve is located inside the second switching element 62. The second switching element 62 controls the second piston valve to open or close the second discharge port, so that the material in the second hopper 12 can be discharged by controlling the second switching element 62. The second switching element 62 also has a reset element 65 for driving the second piston valve to remain in the closed state and a transmission element 64 that is pulsatorically connected to the second piston valve, so as to improve the stability of the material in the second hopper 12 and isolate the material in the hopper from the outside world.

[0053] Furthermore, combined Figure 1 The refrigeration equipment 100 also includes two drip trays 66 arranged side by side. These two drip trays 66 are vertically opposite the first switch 61 and the second switch 62, respectively. The drip trays 66 can be used to hold beverage containers when dispensing beverages, facilitating operation; for example, when dispensing a large quantity of beverages, the user does not need to hold the container by hand. The drip trays 66 can also be used to collect spilled beverages, making cleaning easier.

[0054] Furthermore, the first hopper 11 has a first feed inlet, and the housing 10 is provided with a first cover 71 for sealing the first feed inlet. The user can add material to the first hopper 11 by opening the first cover 71. The first cover 71 and the first hopper 11 can be sealed together, which facilitates the setting of a sealing ring around the periphery of the first feed inlet. Similarly, the second hopper 12 has a second feed inlet and a second cover 72 for sealing the second feed inlet.

[0055] The feeding and discharging structures of the first hopper 11 and the second hopper 12 can be the same, and will not be described in detail here.

[0056] Furthermore, the refrigeration equipment 100 also includes a stirring assembly 80 and a drive assembly. The stirring assembly 80 includes a stirring shaft and stirring blades. The stirring blades are connected to the stirring shaft and extend spirally. The stirring shaft is connected to the drive assembly so that the drive assembly can drive the stirring shaft to rotate, thereby driving the stirring blades to rotate. The stirring blades surround the outer periphery of the evaporator, which can improve the stirring effect and improve the uniformity of cooling of the material in the silo. When the cooling temperature is low, when a frost layer can form on the outer periphery of the evaporator, the stirring blades can scrape off the frost layer to form ice slush.

[0057] Alternatively, the drive unit can be an electric motor.
