Description

Technical Field

[0001] This utility model relates to the field of beverage making equipment technology, and in particular to a discharging component and a beverage machine. Background Technology

[0002] In recent years, a large number of new-style tea drinks have emerged. Their ingredients are basically a mixture of jam, fructose, fruit juice, milk, and tea base. The various ingredients are stored in different containers and are output to the tea drink machine's dispensing end through different dispensing pipes for blending, thus creating tea drinks with corresponding flavors.

[0003] In existing technology, tea beverage machines are equipped with a refrigeration chamber and a storage chamber. The refrigeration chamber is equipped with a cooling system for cooling. Raw materials such as jam, juice, and tea base are stored in the raw material box in the refrigeration chamber. In order to facilitate uniform dispensing, a dispensing base is usually set on the refrigeration chamber so that the dispensing pipe connected to the raw material box can be driven by the pump to convey the raw materials to the dispensing port of the dispensing base, so that the raw materials can be dispensed into the teacup below the dispensing base in a uniform position. Since fructose is prone to solidification in a low-temperature environment, a sugar storage tank containing fructose is set in the storage chamber and then connected to the dispensing port of the dispensing base through a guide pipe. The existing technology has the following defects: the discharge base is in contact with the external environment of the machine body, so the temperature of the discharge base may be higher than that of other parts of the cooling chamber due to the influence of heat exchange with the external environment. This results in the discharge temperature of the discharge base not meeting the requirements for low-temperature storage and transportation of raw materials, and may even cause the raw materials at the discharge port of the discharge base to deteriorate due to temperature. In addition, the uneven heating and stress changes of the discharge base can easily cause it to crack, affecting the safety and service life of the beverage machine. Utility Model Content

[0004] The purpose of this utility model is to provide a dispensing component and a beverage machine, which has a simple structure, and the cold air generated by its refrigeration unit is first connected to the dispensing base through the air guide pipe for cooling, so as to ensure that the temperature of the dispensing base can be uniformly maintained at a low temperature.

[0013] As a preferred embodiment of the discharge assembly, the first side has a wall protruding along the outer edge of the discharge base, and the wall encloses a receiving groove, with the first air guide groove communicating with the receiving groove.

[0014] Secondly, a beverage machine is provided, including a chassis, a feeding component, a sugar feeding component, and a dispensing component as described above.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] like Figures 1 to 5 As shown, the discharge assembly of this utility model embodiment includes a discharge base 1, a vent pipe 2, and a refrigerator 3. The discharge base 1 has a first side 11 arranged along a first direction (the first direction is the opposite of Z in the figure, i.e., the vertical direction). A plug-in post 12 is protruding from the center of the first side 11. The refrigerator 3 is used to generate cold air. The vent pipe 2 has a first end 21 and a second end 22 arranged opposite to each other along its own length direction. The first end 21 is connected to the cold air outlet of the refrigerator 3. The second end 22 is sleeved on the plug-in post 12, and the second end 22 is spaced apart from the first side 11. A plurality of first vent grooves 121 are evenly distributed around the outer peripheral wall of the plug-in post 12 around its own central axis. The length of the first vent grooves 121 extends along the first direction. The first vent grooves 121 are used to discharge the cold air in the vent pipe 2 to the outside of the plug-in post 12. A plurality of discharge ports 13 for discharging material are also provided through the first side 11.

[0031] Understandably, the air guide pipe 2 allows the cold air generated by the refrigeration unit 3 to be connected to the discharge base 1 through the air guide pipe 2, continuously cooling the discharge base 1. This reduces the impact of heat exchange between the discharge base 1 and the external environment, ensuring that the discharge base 1 is always kept at a uniform low temperature. This ensures that the temperature of the discharge base 1 is always kept in a suitable low-temperature environment, reducing the possibility of raw material deterioration due to temperature rise, guaranteeing the quality of raw material discharge and conveying, and reducing the impact of temperature changes on the structural stress of the discharge base 1, thus ensuring the service life of the discharge base 1. The insertion post 12 allows the air guide pipe 2 to connect to the discharge base 1. The air pipe 2 can be directly connected to the plug post 12, improving the connection convenience between the air pipe 2 and the discharge base 1. By uniformly distributing multiple first air guide grooves 121 around the outer periphery of the plug post 12, the cold air output from the air pipe 2 can be evenly diffused to the surrounding area along the center of the discharge base 1. The plug post 12 is located at the center of the first side 11. The cold air in the air pipe 2 is cooled by contact with the plug post 12 and the transfer of the cooled air also spreads from the center of the discharge base 1 to the surrounding area, improving the cooling uniformity of the discharge base 1 and making the temperature change of the entire discharge base 1 area more consistent.

[0032] It should be noted that in this embodiment, one end of the length of the first air guide groove 121 extends to the first side surface 11, and the other end of the length of the first air guide groove 121 passes through the side of the insertion post 12 away from the discharge base 1. That is, when the air guide pipe 2 is sleeved outside the insertion post 12, since the second end 22 of the air guide pipe 2 is spaced from the first side surface 11, a portion of the first air guide groove 121 is located outside the air guide pipe 2. The cold air in the air guide pipe 2 can then be discharged from the first air guide groove 121 to the discharge base to cool the discharge base first. In addition, the refrigeration machine 3 usually adopts a structure with a compressor, condenser, evaporator and fan. After the cold air is generated, it can be driven by the fan to conduct the cold air into the air guide pipe 2. The refrigeration machine 3 is an existing molding equipment and will not be described in detail here.

[0033] Furthermore, such as Figure 2 and Figure 3 As shown, a stepped portion 14 is annularly arranged on the outer peripheral wall of the insertion post 12 around its central axis, and the stepped portion 14 is located adjacent to the first side surface 11. The second end 22 can abut against the stepped portion 14. A second air guide groove 141 is provided on the outer peripheral wall of the stepped portion 14 corresponding to the position of the first air guide groove 121, and the second air guide groove 141 communicates with the first air guide groove 121. By blocking the second end 22 with the stepped portion 14, the installation position of the second end 22 on the insertion post 12 is limited, ensuring that the second end 22 is spaced from the first side surface 11, and that cold air can be discharged from the first air guide groove 121. At the same time, it prevents the air guide tube 2 from being unstable and easily falling off the insertion post 12, thus ensuring the installation stability of the air guide tube 2 and the insertion post 12.

[0034] Preferably, along the first direction, the height of the step portion 14 should be less than or equal to 1 / 3 of the height of the insertion post 12 to ensure the height of the second air guide groove 141. This facilitates the smooth discharge of cold air from the first air guide groove 121 through the second air guide groove 141 and ensures the contact surface between the air guide pipe 2 and the insertion post 12, thereby guaranteeing the connection strength between the air guide pipe 2 and the insertion post 12. Of course, the outer edge of the end of the insertion post 12 furthest from the discharge base 1 can be chamfered. The chamfered inclined surface guides the connection of the second end 22, thereby improving the ease of connection between the second end 22 and the insertion post 12.

[0035] Furthermore, such as Figure 2 and Figure 3As shown, a connecting groove 122 is provided on the side of the insertion post 12 away from the discharge base 1. The first air guide groove 121 communicates with the connecting groove 122. The groove wall of the connecting groove 122 is at least partially inclined, and the inclined groove wall of the connecting groove 122 is inclined from the groove opening towards the groove bottom and close to the central axis of the insertion post 12. By setting the connecting groove 122, the cold air in the air guide pipe 2 can be better connected to the first air guide groove 121 through the connecting groove 122, reducing the obstruction of the cold air on the side of the insertion post 12 away from the discharge base 1. Moreover, by setting the inclined groove wall, the cold air can be effectively guided, reducing the obstruction of the cold air by the groove bottom of the connecting channel, allowing the cold air to flow along the inclined groove wall into the first air guide groove 121, improving the smoothness of the cold air flow.

[0036] In some embodiments, such as Figure 2 and Figure 3 As shown, a connector 15 is annularly protruding along the outer edge of each outlet 13 on the first side 11. The connector 15 is used to connect to the first connecting pipe 52 of the beverage machine. The connector 15 facilitates the assembly and disassembly of the first connecting pipe 52, improving maintenance and cleaning convenience. Furthermore, the annularly protruding connector 15 ensures a tight connection between the first connecting pipe 52 and the connector 15, reducing leakage at the connection point and improving the overall sealing and service life of the piping system. Similarly, the connector 15 can also be used to connect to the second connecting pipe 62 of the beverage machine for syrup dispensing.

[0037] Furthermore, multiple sets of connector groups are provided on the first side 11. Connectors 15 within each connector group are evenly distributed around the insertion post 12. Within the connector group adjacent to the insertion post 12, flow channels 16 are formed at intervals between adjacent connectors 15, and these flow channels 16 correspond one-to-one with the first air guide grooves 121. The one-to-one correspondence between the flow channels 16 formed between the connectors 15 and the first air guide grooves 121 ensures that cold air can be evenly and effectively distributed to the entire discharge base 1 area through the flow channels 16, improving airflow transmission efficiency and preventing cold air from accumulating locally or flowing unevenly, thereby enhancing the overall cooling effect of the discharge base 1.

[0038] Optionally, the inner edge of the end of the connector 15 furthest from the discharge base 1 is chamfered. This chamfer reduces the area of ​​the side of the connector 15 furthest from the discharge base 1, thus reducing the area obstructing the raw material when the connector 15 is inserted into the first connecting pipe 52. Furthermore, the chamfer guides the raw material at the junction of the connector 15 and the first connecting pipe 52, improving the smoothness of material transport and reducing the possibility of material accumulation at the end of the connector 15 furthest from the discharge base 1, which could lead to spoilage and improve food safety.

[0039] Preferably, such as Figure 4 As shown, the discharge base 1 has a second side 17 disposed opposite to the first side 11 along a first direction. The discharge port 13 passes through the first side 11 and the second side 17. A guide portion 18 is provided annularly along the outer edge of each discharge port 13 on the second side 17. By providing the guide portion 18, the material discharged from the discharge port 13 can be effectively guided, reducing the possibility of material flowing along the discharge port 13 to the second side 17 and contaminating the second side 17, thereby improving the safety of the discharge base 1 in use.

[0040] Furthermore, such as Figure 2 As shown, a surrounding wall 19 protrudes from the outer edge of the discharge base 1 on the first side 11, forming a receiving groove 20. The first air guide groove 121 communicates with the receiving groove 20. The receiving groove 20 is formed by the surrounding wall 19, so that cold air can flow into the receiving groove 20 through the first air guide groove 121, thereby increasing the residence time of the cold air in the receiving groove 20 and thus increasing the possibility of heat exchange between the cold air and the discharge base 1.

[0041] like Figures 1 to 5 As shown, an embodiment of this utility model also provides a beverage machine, including a housing 4, a feeding component 5, a sugar feeding component 6, and a discharging component as described in any of the above embodiments. The housing 4 is provided with a first placement area 41, a second placement area 42, and a discharging area 43 spaced apart. The first placement area 41 and the discharging area 43 are cooling areas. In this embodiment, the first placement area 41 and the discharging area 43 are connected. The housing 4 is provided with an installation port that communicates with the discharging area 43. The discharging base 1 of the discharging component is provided at the installation port. The feeding component 5 includes a first connecting pipe 52 and a raw material box 51 disposed in the first placement area 41. The raw material box 51 is connected to a discharging port 13 of the discharging base 1 through the first connecting pipe 52. The sugar feeding component 6 includes a second connecting pipe 62 and a syrup box 61 disposed in the second placement area 42. One end of the second connecting pipe 62 is connected to the syrup box 61, and the end of the second connecting pipe 62 away from the syrup box 61 extends into the discharging area 43 and is connected to another discharging port 13 of the discharging base 1.

[0042] It is understandable that the fructose in the syrup box 61 and the second connecting pipe 62 of the beverage machine should be kept above 25°C, that is, at least at room temperature, to ensure the safety of fructose storage while maintaining its fluidity. Meanwhile, the raw materials such as jam, juice, milk, and tea base should be kept below 5°C in the raw material box 51 and the first connecting pipe 52 to ensure their safety during storage. Therefore, the air guide pipe 2 allows the cold air generated by the refrigeration unit 3 to be connected to the dispensing base 1 through the air guide pipe 2 to continuously cool the dispensing base 1 before transferring the cold air to the placement chamber. This reduces the impact of heat exchange between the dispensing base 1 and the external environment, ensuring that the dispensing base 1 is always kept at a uniformly low temperature. This ensures that the temperature of the dispensing base 1 is always maintained at a suitable low temperature of 5°C, reducing the possibility of raw material deterioration due to temperature increases, ensuring the quality of raw materials stored in the placement chamber and during dispensing, and reducing the impact of temperature changes on the structural stress of the dispensing base 1, thus ensuring the service life of the dispensing base 1. By placing the syrup box 61 and the second connecting pipe 62 in the second placement area 42, which is spaced apart from the placement cavity, the temperature of the fructose in the syrup box 61 and the second connecting pipe 62 is maintained, thereby ensuring the smooth transport of fructose.

[0043] In addition, heat insulation pads can be installed on the inner and outer walls of the partition plate 44 between the dispensing area 43 and the second placement area 42 of the beverage machine to reduce heat loss in the placement cavity, so that the cold air in the placement cavity can be better retained and energy consumption can be reduced.

[0044] Furthermore, the beverage machine also includes a rinsing assembly 7, which includes a water tank 71, a first water outlet pipe 72, a first three-way valve 73, and a first pump body. The water tank 71 is disposed in the placement cavity. One end of the first water outlet pipe 72 is connected to the water tank 71, and the other end of the first water outlet pipe 72 is connected to the second connecting pipe 62 through the first three-way valve 73. The first three-way valve 73 is disposed in the second placement area 42 and adjacent to the placement cavity. The first pump body is disposed on the first water outlet pipe 72. By setting up the flushing component 7, after the fructose is conveyed by the second pump body through the second connecting pipe 62, the sugar supply component 6 can be driven by the first pump body to flush the fructose between the outlet 13 and the first three-way valve 73 of the second connecting pipe 62 with purified water from the water tank 71 through the first water outlet pipe 72. This prevents the fructose in the second connecting pipe 62 from being refrigerated and crystallizing and clogging the placement chamber, thus improving the unobstructed flow of the second connecting pipe 62. It also ensures the hygiene and safety of the outlet 13 and the end of the second connecting pipe 62 adjacent to the outlet 13, preventing the growth of bacteria from residual fructose, ensuring the normal use of the beverage machine and the food safety of the tea.

[0045] In addition, the flushing assembly 7 may also include a second water outlet pipe 74, a second three-way valve 75, and a second pump body. The water tank 71 is disposed in the placement cavity. One end of the second water outlet pipe 74 is connected to the water tank 71, and the other end of the second water outlet pipe 74 is connected to the first connecting pipe 52 through the second three-way valve 75. The second three-way valve 75 is disposed adjacent to the discharge base 1, and the first pump body is disposed on the second water outlet pipe 74. After the first pump body drives the first connecting pipe 52 to deliver the raw materials, the valve connecting the first pump body and the second three-way valve 75 to the raw material box 51 is closed. The second pump body drives the second water outlet pipe 74 to flush the portion of the first connecting pipe 52 located between the discharge port 13 and the second three-way valve 75 with purified water from the water tank 71. This reduces the amount of raw materials left at the discharge port 13 and the end of the first connecting pipe 52 near the bottom of the liquid outlet, preventing bacterial growth and improving the safety of the beverage machine.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
