Description

Technical Field

[0001] This application relates to the field of cold drink machine technology, specifically to a dispensing mechanism and a vertical cold drink machine. Background Technology

[0002] A beverage cooler is a device that can cool beverages to prepare cold drinks. Most existing beverage coolers include a storage tank and a refrigeration mechanism. The storage tank is used to hold room temperature beverages, and the refrigeration mechanism is used to cool the beverages in the storage tank.

[0003] A typical beverage storage container includes an inlet and an outlet. In vertical beverage dispensers, the bottom of the container usually has an outlet with a support for dispensing beverages. This support works in conjunction with the dispensing switch to easily collect the beverages from the container. However, most dispensing supports are made of plastic. As the beverages flow out through the support, heat exchange occurs between the beverage and the support. After cooling, the support then exchanges heat with the outside air. Since the outside air temperature is generally higher than the support, condensation forms on the support, affecting the appearance and hygiene of the beverages when dispensed.

[0004] Therefore, the dispensing support of the existing cold drink machine has room for further improvement. Utility Model Content

[0005] In view of this, and in response to the technical problem that condensation easily forms at the dispensing end of the existing vertical beverage dispenser, this application provides a dispensing mechanism and a vertical beverage dispenser. The dispensing mechanism is equipped with a heat preservation structure that can hold heat preservation material, thereby achieving heat preservation at the dispensing end of the beverage dispenser and reducing the formation of condensation at the dispensing end.

[0006] In a first aspect, this application provides a dispensing mechanism for use in a slush machine or a beverage cooler, comprising:

[0007] The discharge support is located at the discharge end of the storage tank and is equipped with a heat preservation cavity;

[0008] The discharge switch, located at the discharge end of the discharge support, is used to control the liquid discharge rate from the storage tank.

[0009] A heat insulation component, located inside the heat insulation cavity, is used to insulate the discharge support.

[0010] Compared with the prior art, the discharge mechanism provided in this application includes a discharge support, a discharge switch, and a heat insulation component. The discharge support is connected to the discharge end of the storage tank and has a heat insulation cavity for installing the heat insulation component. This allows the discharge support to be kept warm through the heat insulation component. Even if the discharge support comes into contact with the liquid in the storage tank and cools down, the heat transfer between the inner and outer layers of the discharge support can be reduced under the action of the heat insulation component. This results in a smaller temperature difference between the outer surface of the discharge support and the outside air, reducing the probability of condensation on the discharge support and thus improving aesthetics and hygiene.

[0019] In this embodiment, the first insulation cavity is arranged around the central axis, and the discharge channel is located on the first insulation cavity. When the first insulation component is installed in the first insulation cavity, it can simultaneously insulate the bottom of the storage tank and the discharge channel. The second insulation cavity is located outside the discharge channel, which can compensate for the thinness of the corresponding first insulation component caused by the structure of the discharge channel, thereby ensuring that the outside of the discharge channel has sufficient insulation and reducing the formation of condensate on the outside of the discharge channel.

[0020] Preferably, the insulation part includes:

[0021] The inner shell has a smaller inner diameter than the storage tank's inner diameter.

[0025] Preferably, the insulation part further includes a limiting post located between the inner shell and the outer shell, with its top connected to the limiting plate and its bottom having a limiting opening;

[0026] The first insulation component is provided with an installation port, which is coaxially arranged with the limiting port for inserting the same connector.

[0027] In this embodiment, the cooperation between the limiting post and the mounting port enables the first insulation component to be stably installed in the first insulation cavity.

[0028] Preferably, the insulation part further includes:

[0029] The mounting side plate is located on the outer side of the outer casing corresponding to the discharge channel and protrudes outward in a radial direction;

[0030] The mounting baffle is located on the side of the mounting side plate away from the outer shell, and together with the mounting side plate and the outer shell, it forms the second insulation cavity.

[0031] In this embodiment, by setting the mounting side plate to protrude radially, it can form a second heat insulation cavity together with the mounting baffle and the outer shell, thereby reducing the amount of materials needed and saving costs.

[0032] Preferably, the insulation part further includes:

[0033] The mounting ring is located inside the second insulation cavity and protrudes outward in a radial direction;

[0034] The mounting protrusion is located on the side of the mounting baffle facing the outer casing and is used to insert into the mounting ring post.

[0035] In this embodiment, the mounting ring column and the mounting protrusion cooperate to achieve the connection between the mounting baffle and the mounting side plate without the need for additional connecting parts, resulting in a simple structure.

[0036] Preferably, it also includes a sealing base plate, which is disposed at the bottom of the discharge support;

[0038] In this embodiment, the discharge support and the sealing base plate are separate structures, which reduces the manufacturing difficulty of the discharge mechanism; the insulation component is made of at least one of foamed polypropylene, polyurethane, and polyethylene, which has low cost and good insulation effect.

[0041] A refrigeration device for cooling the liquid in a storage tank, including an evaporator;

[0042] Mounting bracket for mounting the refrigeration device;

[0043] A heat exchange cylinder, coaxially mounted inside a storage tank, is used to install the evaporation tube.

[0044] Compared with the prior art, the vertical cold drink machine of this application is equipped with a refrigeration device that can cool down the liquid in the storage tank to form a cold drink; the heat exchange cylinder can be equipped with an evaporation tube, so that the evaporation tube can be located in the storage tank to quickly cool down the liquid.

[0045] Preferred options also include:

[0047] The driving mechanism includes a rotating shaft and a driving motor for driving the stirring mechanism to rotate; wherein, one end of the rotating shaft is connected to the driving motor, and the other end passes through the heat exchange cylinder axially and is connected to the stirring mechanism;

[0048] The third insulation component, a ring structure, is sleeved outside the rotating shaft; the evaporation tube is spirally wound around the outside of the third insulation component.

[0049] A limiting sleeve is fitted over the third insulation component to limit the displacement of the evaporator tube toward the central axis.

[0050] In this embodiment, the driving mechanism can drive the stirring mechanism to rotate inside the storage tank, so that the liquid cools down evenly. A third heat insulation component is set between the evaporation tube and the rotating shaft, which can isolate the evaporation tube from contact with the rotating shaft while ensuring that the low temperature of the evaporation tube is supplied to the liquid in the storage tank, thus ensuring the cooling effect. The limiting sleeve acts outside the third heat insulation component, which can axially limit the evaporation tube, so that the evaporation tube is tightly attached to the inner wall of the heat exchange cylinder, while also preventing debris from the third heat insulation component from entering the gaps of the evaporation tube, thus ensuring the working efficiency of the evaporation tube.

Therefore, the above terms should not be construed as limitations on this application.

[0067] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 8 illustrate.

[0068] First aspect

[0069] This application provides a discharging mechanism for use in a cold drink machine or slush machine. It is installed at the discharging end of the storage tank 2 and is used to install the storage tank 2 and control the discharging of the storage tank 2.

[0070] Specifically, such as Figures 1 to 8As shown, the discharge mechanism includes a discharge support 1, a discharge switch 3, and a heat insulation component. The discharge support 1 has an inlet end and a discharge end. The inlet end of the discharge support 1 is connected to the discharge end of the storage tank 2, that is, the discharge support 1 is connected to the storage tank 2. The discharge switch 3 is located at the discharge end of the discharge support 1. By controlling the liquid discharge rate at the discharge end of the discharge support 1, the liquid discharge rate of the storage tank 2 can be controlled. The discharge support 1 is provided with a heat insulation cavity, and the heat insulation component is located in the heat insulation cavity. The heat insulation component insulates the discharge support 1. Even if the discharge support 1 comes into contact with the liquid in the storage tank and cools down, the heat transfer between the inner and outer layers of the discharge support 1 can be reduced under the action of the heat insulation component. This results in a smaller temperature difference between the outer surface of the discharge support 1 and the outside air, reducing the probability of condensation on the discharge support 1, thereby improving aesthetics and hygiene.

[0071] In this application, the insulation component is made of insulation material, which is made of at least one of foamed polypropylene, polyurethane, and polyethylene; of course, other insulation materials with high safety and suitable for the food industry can also be used.

[0072] Furthermore, the discharge support 1 is described in more detail; such as Figures 3 to 6 As shown, the discharge support 1 includes an installation part 101 and an insulation part 102. The installation part 101 is located on the upper end of the insulation part 102. The installation part 101 is basically a cylindrical structure. The inner wall of the installation part 101 is provided with threads, and the outer wall of the discharge end of the storage tank 2 is provided with threads so that the storage tank 2 and the installation part 101 are connected by threads.

[0073] The insulation section 102 is located at the bottom of the mounting section 101 and at the bottom of the storage tank 2. An insulation cavity is disposed on the insulation section 102, meaning the insulation components are mainly installed on the insulation section 102 to effectively insulate the bottom of the storage tank 2 and the discharge end of the discharge support 1. The insulation section 102 has a discharge channel 103, which is parallel to the axial direction and connected to the mounting section 101 at its upper end. The lower end of the discharge channel 103 is opened and closed via a discharge switch 3, which is installed at the discharge end of the discharge channel 103. In this embodiment, the discharge channel 103 is disposed on the insulation section 102, and the insulation components installed on the insulation section 102 can insulate the discharge channel 103, thereby ensuring insulation at the discharge channel 103 and further reducing the formation of condensate on the outside of the discharge support 1.

[0074] Among them, such as Figure 2 , Figures 7 to 8 As shown, the insulation cavity is divided into a first insulation cavity 104 and a second insulation cavity 105, and the insulation assembly includes a first insulation component 4 and a second insulation component 5; as Figures 2 to 8As shown, the insulation section 102 has a double-layer structure, including an inner shell 1021 and an outer shell 1022. Both the inner shell 1021 and the outer shell 1022 are cylindrical structures. The inner shell 1021 and the outer shell 1022 are coaxially arranged, and the outer shell 1022 is fitted over the inner shell 1021. The inner diameter of the inner shell 1021 is smaller than the inner diameter of the storage tank 2, and the inner diameter of the outer shell 1022 is larger than the inner diameter of the storage tank 2. There is a radial gap between the inner shell 1021 and the outer shell 1022, thereby forming the first insulation cavity 104. Figure 5 As shown, the first insulation cavity 104 is roughly an annular structure. The first insulation cavity 104 is arranged around the central axis of the storage tank 2. The inner diameter of the first insulation cavity 104 is smaller than the inner diameter of the storage tank 2, and the outer diameter of the first insulation cavity 104 is larger than the inner diameter of the storage tank 2. When the first insulation component 4 is installed in the first insulation cavity 104, the effective area of ​​the first insulation component 4 is large, which can provide more comprehensive insulation for the bottom of the storage tank 2 and the bottom of the discharge support 1, further reducing the probability of condensation forming on the outer surface of the discharge support 1.

[0075] In this embodiment, the structure of the first insulation component 4 corresponds to and is adapted to the structure of the first insulation cavity 104. For example... Figure 5 As shown, the insulation part 102 also includes a limiting post 1025, which is disposed between the inner shell 1021 and the outer shell 1022. The limiting post 1025 is an annular columnar structure and extends parallel to the central axis. The top of the limiting post 1025 is connected to the insulation part 102, and the bottom is provided with a limiting opening. The first insulation member 4 is provided with an installation port, which penetrates the first insulation member 4 parallel to the axial direction. The installation port and the limiting port are coaxially arranged to allow the insertion of screws or other connecting parts, thereby fixing the first insulation member 4 to the limiting post 1025 so that the first insulation member 4 can be stably installed in the first insulation cavity 104. In this embodiment, multiple limiting posts 1025 are provided, and the multiple limiting posts 1025 are arranged at intervals along the circumference of the first insulation cavity 104. The position and number of the installation ports correspond to the mounting annular posts 1028.

[0076] Furthermore, such as Figure 5 As shown, the outer side wall of the inner shell 1021 is provided with a plurality of reinforcing ribs. The reinforcing ribs extend axially and protrude radially toward the outer shell 1022 to increase the friction between the first insulation member 4 and the inner shell 1021, thereby ensuring the stable installation of the first insulation member 4 in the first insulation cavity 104.

[0077] like Figure 4 , Figure 8As shown, the insulation section 102 also includes a mounting side plate 1026 and a mounting baffle 1027. The mounting side plate 1026 has a rectangular n-shaped structure or an orifice-shaped structure. The mounting side plate 1026 is located on the outside of the outer shell 1022 corresponding to the discharge channel 103, and it protrudes radially outward. The mounting baffle 1027 is connected to the side of the mounting side plate 1026 away from the outer shell 1022, thereby forming a second insulation cavity 105 together with the mounting baffle 1027, the mounting side plate 1026, and the outer shell 1022. The second insulation cavity 105 is located on the outside of the discharge channel 103, and the circumferential length of the second insulation cavity 105 is... The second insulation component 5 is larger than the circumferential length of the discharge channel 103, thus fully covering the outer side of the discharge channel 103. When the second insulation component 5 is installed in the second insulation cavity 105, the second insulation component 5 can fully cover the outer side of the discharge channel 103 to ensure the insulation effect on the outer side of the discharge channel 103. In this embodiment, due to the setting of the discharge channel 103, the first insulation cavity 104 corresponding to the discharge channel 103 is relatively thin. Therefore, the setting of the second insulation cavity 105 can supplement it, thereby ensuring that the outer side of the discharge channel 103 has sufficient insulation and reducing the formation of condensate on the outer side of the discharge channel 103.

[0078] Among them, such as Figure 3 As shown, the insulation part 102 is also provided with a mounting ring post 1028 and a mounting protrusion. The mounting ring post 1028 is a ring structure and is disposed in the second insulation cavity 105. The mounting ring post 1028 is connected to the outer wall of the outer shell 1022 and protrudes radially outward. The mounting protrusion is disposed on the mounting baffle 1027 and is located on the side of the mounting baffle 1027 facing the outer shell 1022. The mounting protrusion is a columnar structure and its outer diameter is slightly larger than the hole diameter of the mounting ring post 1028. The mounting protrusion is coaxially disposed with the mounting ring post 1028 and is used to insert into the hole of the mounting ring post 1028 to achieve the connection and fixation between the mounting baffle 1027 and the outer shell 1022. There is at least one mounting ring post 1028, and the position and number of the mounting protrusions correspond to the mounting ring post 1028.

[0079] In this embodiment, the mounting baffle 1027 can block the opening end of the mounting side plate 1026, thereby limiting the second insulation component 5 within the second insulation cavity 105 and ensuring the stable installation of the second insulation component 5 on the discharge support 1.

[0080] Furthermore, the discharge support 1 is described in more detail; such as Figures 3 to 7As shown, the discharge support 1 also includes a limiting top plate 1023 and a limiting bottom plate 1024. Both the limiting top plate 1023 and the limiting bottom plate 1024 are flat ring structures. The limiting top plate 1023 is connected to the outer side of the top of the inner shell 1021. The outer side of the limiting top plate 1023 is connected to the mounting part 101 to support the bottom of the storage tank 2 and limit the axial movement of the storage tank 2, so as to ensure the connection stability between the storage tank 2 and the discharge support 1.

[0081] The limiting base plate 1024 is connected to the inner side of the bottom of the inner shell 1021. The inner diameter of the limiting base plate 1024 is smaller than that of the inner shell 1021. The setting of the limiting base plate 1024 can increase the connection area between the first heat preservation component 4 and the discharge support 1 in the axial direction, and at the same time increase the heat preservation area of ​​the bottom of the storage tank 2 and the bottom of the discharge support 1, thereby further increasing the heat preservation effect and reducing the probability of condensation formation.

[0082] Furthermore, such as Figure 2 As shown, the discharge mechanism also includes a sealing base plate, which is located at the bottom of the discharge support 1 and can seal the bottom of the discharge support 1. At the same time, the discharge support 1 and the sealing base plate are separate structures, which reduces the manufacturing difficulty of the discharge mechanism and facilitates the installation of the discharge mechanism.

[0083] Second aspect

[0084] This application provides a vertical beverage cooler, which includes the dispensing mechanism in any embodiment provided in the first aspect; it also includes at least one storage tank 2, a refrigeration device 7, a mounting base 12, a stirring mechanism 9, a driving mechanism 10, and a heat exchange cylinder 8; as shown Figure 1 , Figure 2 As shown, the mounting base 12 is a shell structure used to install the refrigeration device 7; the refrigeration device 7 can cool and refrigerate the liquid, and includes an evaporator tube 701; the stirring mechanism 9 is sleeved outside the heat exchange cylinder 8, and the stirring mechanism 9 can stir the liquid, which on the one hand makes the heat exchange of the liquid in the storage tank 2 uniform, and on the other hand can cut the ice in the storage tank 2 to prevent the liquid from forming large ice clumps, thereby stably forming slushy or non-slushy cold drinks with different freezing degrees to meet the user's needs; the driving mechanism 10 is connected to the stirring mechanism 9 and is used to drive the stirring mechanism 9 to rotate in the storage tank 2; the heat exchange cylinder 8 is set in the storage tank 2 and is used to install the driving mechanism 10 and the evaporator tube 701.

[0085] Specifically, such as Figures 1 to 2As shown, the refrigeration device 7 includes a condenser 702, a compressor 703, and an evaporator. The compressor 703, condenser 702, and evaporator together form a refrigeration cycle system for cooling the liquid in the storage tank 2. The evaporator includes an evaporation tube 701, which is spirally wound inside the heat exchange cylinder 8 to exchange heat and cool the liquid in the storage tank 2. The storage tank 2 is connected to the mounting base 12 via a discharge support 1, wherein one side of the discharge support 1 is connected to the mounting base 12, and the other side is the handle of the discharge switch 3. The discharge support 1 is connected to the middle of the mounting base 12. The storage tank 2 is arranged vertically, and both ends of the storage tank 2 are provided with threaded portions. The bottom of the storage tank 2 is threadedly connected to the discharge support 1, and the storage tank 2 is threadedly connected to the tank cover.

[0086] The heat exchange cylinder 8 has a cylindrical structure and is coaxially arranged with the storage tank 2. The outer diameter of the heat exchange cylinder 8 is smaller than the inner diameter of the storage tank 2 to reserve space for liquid. The drive mechanism 10 includes a drive motor 1002 and a rotating shaft 1001. The bottom of the rotating shaft 1001 is connected to the drive motor 1002, and the top passes through the heat exchange cylinder 8 and is connected to the stirring mechanism 9. The drive motor 1002 drives the rotating shaft 1001 to rotate, and the rotating shaft 1001 then drives the stirring mechanism 9 to rotate. The rotating shaft 1001 is located inside the heat exchange cylinder 8, and the drive motor 1002 is located at the bottom of the heat exchange cylinder 8. The heat exchange cylinder 8 can protect the rotating shaft 1001 and the drive motor 1002, prevent the liquid from contacting the drive motor 1002 and the rotating shaft 1001, and prevent contamination of the liquid. The rotating shaft 1001 is rotatably connected to the top of the heat exchange cylinder 8. The stirring mechanism 9 is sleeved on the outside of the heat exchange cylinder 8, and both the stirring mechanism 9 and the rotating shaft 1001 can rotate relative to the heat exchange cylinder 8. The heat exchange cylinder 8 and the drive motor 1002 are fixed relative to the storage tank 2.

[0087] The evaporator tube 701 is spirally wound around the rotating shaft 1001, and a safety sleeve is provided outside the rotating shaft 1001 to prevent the evaporator from directly contacting the rotating shaft 1001.

[0088] Based on any of the above embodiments, the vertical beverage cooler can be further extended; such as... Figure 2 , Figure 7 , Figure 8 As shown, the vertical beverage cooler also includes a third insulation component 6, which is made of insulation material and is configured as a ring structure. The third insulation component 6 is sleeved on the outside of the rotating shaft 1001, and the evaporation tube 701 is wrapped around the outside of the third insulation component 6. That is, the third insulation component 6 acts between the evaporation tube 701 and the rotating shaft 1001. The third insulation component 6 can isolate the evaporation tube 701 from contact with the rotating shaft 1001, while ensuring that the low temperature of the evaporation tube 701 basically supplies the liquid in the storage tank 2, thus ensuring the cooling effect.

[0089] Furthermore, such as Figure 7 , Figure 8 As shown, the vertical beverage cooler also includes a limiting sleeve 11. The limiting sleeve 11 is a cylindrical structure made of metal. The limiting sleeve 11 is sleeved on the outside of the third insulation component 6. The limiting sleeve 11 can axially limit the evaporation tube 701, restricting the displacement of the evaporation tube 701 towards the central axis, so that the evaporation tube 701 is tightly attached to the inner wall of the heat exchange cylinder 8, so as to ensure the cooling effect of the evaporation tube 701 on the liquid in the storage tank 2. It can also prevent the debris of the third insulation component 6 from entering the gap of the evaporation tube 701, thus ensuring the working efficiency of the evaporation tube 701.
