Description

Technical Field

[0001] This invention relates to the field of beverage making equipment technology, specifically to a beverage making system and beverage making equipment. Background Technology

[0002] With the advancement of technology, people's demands for quality of life are gradually increasing. This is reflected in all aspects, such as the growing demand for a wider variety of beverages. Existing beverage-making equipment, such as coffee machines, generally uses high-temperature extraction to produce coffee from coffee powder. The resulting coffee is usually quite hot. When users want to enjoy cold coffee, they typically add ice cubes manually to the hot coffee outside the machine. However, this method easily dilutes the coffee with ice, reducing its drinking quality. Summary of the Invention

[0014] The second valve body can control the on / off connection between the third pipeline and the second input pipeline segment.

[0015] Optionally, the beverage preparation system further includes a waste discharge pipeline, one end of which is connected to another valve port of the second valve body, and the other end of which is used to connect to an external slag collection structure.

[0016] The second valve body can control the opening and closing of the third pipeline and the waste discharge pipeline.

[0017] Optionally, the beverage preparation system further includes a gas-expelling component;

[0018] The air-driving component is disposed in the hot beverage flow path from the outlet end of the beverage preparation tank to the beverage outlet, so as to blow the hot beverage remaining in the hot beverage flow path into the beverage preparation tank, or blow it outward through the beverage outlet; and / or,

[0019] The air-driving component is disposed on the cold beverage flow path from the outlet end of the receiving channel to the beverage outlet, so as to blow the cold beverage remaining in the cold beverage flow path into the receiving channel or blow it out through the beverage outlet.

[0020] Optionally, the air-driving assembly includes an air volume regulator and an air pump, wherein the air pump operates according to a preset air pressure value set by the air volume regulator.

[0021] Optionally, the cooling structure is disposed within the receiving channel; and / or,

[0022] The refrigeration structure is located outside the receiving channel.

[0023] Optionally, the refrigeration body is further provided with a refrigeration channel, and the refrigeration channel and the receiving channel are connected for heat exchange.

[0024] The drinking system also includes a cold water assembly, which includes an inlet pipe and a pump body. One end of the inlet pipe is connected to an external cold water source, and the other end of the inlet pipe is connected to the inlet of the refrigeration channel.

[0025] The refrigeration channel and the cold water connected to it together constitute the refrigeration structure.

[0026] Optionally, the refrigeration aisle is arranged around the entire periphery of the receiving aisle.

[0027] Optionally, the refrigeration body includes an inner tube and an outer tube that are connected together. The inner tube defines the receiving channel inside, and the inner wall of the outer tube and the outer wall of the inner tube are spaced apart to define the refrigeration channel at the space.

[0035] Optionally, the pump body is located at the fifth pipeline.

[0036] In addition, to achieve the above objectives, the present invention also proposes a beverage making device, including a housing and a beverage making system disposed in the housing, wherein the beverage making system is the beverage making system described above.

[0037] In the technical solution provided by this invention, after the beverage-making component prepares a hot beverage, it can be directly output through the beverage-making tank and the output pipeline to finally obtain a hot beverage product.

[0038] Alternatively, after the beverage-making unit prepares a hot beverage, it can be fed into the receiving channel through the beverage-making tank. During this process, the nearby refrigeration structure cools the hot beverage. Once the hot beverage is cooled into a cold beverage, it is directly output through the receiving channel and the output pipe, ultimately yielding a cold beverage product.

[0039] This application, through a relatively simple structural design, allows for switching between hot and cold beverage output. Furthermore, it utilizes a refrigeration structure to cool the hot beverage flowing within the receiving channel. While cooling, the independent flow of hot beverages is maintained, meaning no other liquid needs to be added to the hot beverage, thus preventing a decrease in the quality of the resulting cold beverage.

[0052] Please see Figures 1 to 5 The present invention provides a beverage preparation system and an applicable device for making beverages.

[0053] The beverage making system includes a beverage making component 100, a refrigeration component 200, and an output pipeline 300.

[0054] The beverage preparation unit 100 is used to receive powdered materials and, after being connected to high-temperature hot water, to extract the powdered materials for beverage preparation, ultimately obtaining a hot beverage. Specifically, the beverage preparation unit 100 includes a beverage preparation tank 110. The internal space of the beverage preparation tank 110 can be used to achieve the aforementioned purposes of receiving powdered materials and extracting beverages. Therefore, the hot beverage obtained is temporarily stored in the beverage preparation tank 110.

[0055] Of course, depending on actual needs, the beverage preparation component 100 may also include, for example, a piston assembly for pressing powder to obtain powder cake, a power component for driving the beverage preparation cylinder 110 to switch between the powder receiving position and the beverage preparation position, etc., which will not be described in detail.

[0056] Next, in order to provide powder to the beverage making component 100, the beverage making system may also include a powder supply component.

[0057] The powder supply assembly can be directly configured to include a powder storage bin. In this case, the powder storage bin is directly used to store the already ground powder. When needed, simply connect the flow path between the powder storage bin and the beverage preparation tank 110.

[0058] Alternatively, the powder supply assembly can be configured as a bean storage bin and a grinding assembly. In this case, the bean storage bin is used to store the beans. Once the flow path between the bean storage bin and the grinding assembly is open, the beans in the bean storage bin can enter the grinding assembly. The grinding assembly grinds the beans to obtain powder. Then, once the flow path between the grinding assembly and the beverage preparation tank 110 is open, the powder is transferred into the beverage preparation tank 110.

[0059] Similarly, in order to provide high-temperature hot water to the drinking water unit 100, the drinking water system may also include a cold water unit 700 and a boiler unit 800. The cold water unit 700 includes an inlet pipe 710 and a pump body 720. The boiler unit 800 includes a boiler body 810. One end of the inlet pipe 710 is connected to an external water source, and the other end of the inlet pipe 710 is connected to the boiler body 810.

[0060] When the water inlet pipe 710 and the boiler body 810 are connected, the water inlet pipe 710 can introduce external cold water into the boiler body 810. Then, the cold water in the boiler body 810 is heated by the heating element fixed within the boiler assembly 800 to obtain high-temperature hot water. Next, when the flow path between the boiler body 810 and the beverage preparation tank 110 is connected, the high-temperature hot water can be introduced into the beverage preparation tank 110 to extract and process the powder within the beverage preparation tank 110.

[0061] The refrigeration assembly 200 includes a refrigeration body 210 for cooling hot beverages to obtain cold beverages. It is understood that the refrigeration body 210 is provided with at least a receiving channel 211a. The inlet end of the receiving channel 211a is connected to the outlet end of the beverage preparation tank 110 so as to be able to receive hot beverages stored in the beverage preparation tank 110.

[0062] The refrigeration unit 210 is further provided with a refrigeration structure on the adjacent side of the receiving channel 211a. When hot beverages flow in the receiving channel 211a, the refrigeration structure can exchange heat with the hot beverages in the receiving channel 211a. Through heat exchange, the temperature of the hot beverages can be effectively reduced, thereby obtaining cold beverages.

[0063] The specific structural form of the refrigeration structure is not limited. The refrigeration structure can be built into the receiving channel 211a. However, it should be noted that when the refrigeration structure in this embodiment is built into the receiving channel 211a, it will not introduce liquid or other substances into the hot beverage flowing in the receiving channel 211a, that is, it ensures that it will not interfere with the quality of the cold beverage obtained after cooling.

[0064] The cooling structure at this time can be, but is not limited to, various cooling devices, such as semiconductor coolers. In practical applications, the entire cooling body 210 can be directly made of semiconductor materials. In this way, the receiving channel 211a can be directly defined by the semiconductor cooling material. Consequently, the semiconductor cooling material can directly act on the hot beverage flowing within the receiving channel 211a.

[0065] Of course, the refrigeration structure can also be located outside the receiving channel 211a. For example, the refrigeration body 210 also has a refrigeration channel 212a extending through it on the adjacent side of the receiving channel 211a. The refrigeration channel 212a can be used to circulate refrigeration gas, chilled water, or is filled with phase change material.

[0066] The cooling aisle 212a may be located on one side or at least both sides of the receiving aisle 211a. Alternatively, the cooling aisle 212a may be arranged around the entire periphery of the receiving aisle 211a.

[0067] When cold water flows through the refrigeration channel 212a, the beverage making system further includes a cold water assembly 700. The cold water assembly 700 includes an inlet pipe 710 and a pump body 720. One end of the inlet pipe 710 is connected to an external cold water source. The other end of the inlet pipe 710 can be connected to the inlet of the refrigeration channel 212a. Driven by the pump body 720, external cold water can enter the refrigeration channel 212a through the inlet pipe 710. During this process, the cold water in the refrigeration channel 212a exchanges heat with the hot beverage in the receiving channel 211a, achieving the purpose of cooling the hot beverage.

[0068] The chilled water component 700 mentioned above may be specifically designed for the refrigeration component 200. That is, the chilled water component 700 associated with the refrigeration component 200 and the chilled water component 700 associated with the boiler component 800 mentioned above are not the same component; they are independent of each other and distinct from one another.

[0069] For example, the chilled water unit 700, which is dedicated to the refrigeration unit 200, can be connected to chilled water at a relatively lower temperature. Meanwhile, the chilled water unit 700, which is dedicated to the boiler unit 800, can be connected to chilled water at a relatively higher temperature.

[0070] Of course, the refrigeration unit 200 and the boiler unit 800 can also share the same chilled water unit 700. In this case, the inlet water pipe 710 can be connected to the refrigeration channel 212a and the boiler body 810 respectively. Or as... Figure 1 , Figures 4 to 5 As shown, the water inlet pipe 710 is connected to the inlet end of the refrigeration channel 212a. Then, the outlet end of the refrigeration channel 212a is connected to the boiler body 810 via the fifth pipe 550. In this way, cold water exchanges heat with hot beverages within the refrigeration channel 212a to form warm water before entering the boiler body 810. This results in a relatively small temperature difference between the water added to the boiler body 810 and the target hot water, further contributing to energy conservation and consumption reduction in the boiler body 810.

[0071] The connection position of the fifth pipe 550 at the refrigeration aisle 212a is not restricted:

[0072] In one specific embodiment, the fifth pipe 550 can be directly connected to the outlet end of the refrigeration channel 212a. In this case, all the water flowing in the refrigeration channel 212a will be connected to the fifth pipe 550 and the boiler body 810.

[0073] It is understandable that when the flow rate of warm water circulating in the cooling channel 212a is just enough to meet or less than the water replenishment requirements of the boiler body 810, the warm water in the cooling channel 212a can be completely connected to the boiler body 810 as described above. This ensures that a sufficient amount of warm water is provided to the boiler body 810, ensuring that the water replenishment of the boiler body 810 is more timely and sufficient.

[0074] Alternatively, in another specific embodiment, the fifth pipe 550 can be connected to the middle section of the refrigeration channel 212a (meaning any section between the inlet and outlet, not limited to the midpoint of the refrigeration channel 212a). However, it is preferable to position the connection between the fifth pipe 550 and the refrigeration channel 212a closer to the outlet of the refrigeration channel 212a. This allows some of the water in the refrigeration channel 212a to be connected to the fifth pipe 550 and the boiler body 810.

[0075] It is understandable that when the flow rate of warm water in the cooling channel 212a exceeds the water replenishment requirement of the boiler body 810, the warm water in the cooling channel 212a can be partially diverted into the boiler body 810. The remaining warm water in the cooling channel 212a can be treated in the following way:

[0076] For example, the remaining warm water can be returned to the inlet or upstream section of the refrigeration channel 212a via an additional bypass pipe, continuing to participate in the next refrigeration cycle for hot drinks together with the newly added cold water. Since the volume of the remaining warm water is relatively small compared to the volume of water supplied to the boiler body 810 or the volume of cold water added to the refrigeration channel 212a, the mixing of this remaining warm water with the newly added cold water will not cause an excessive increase in overall water temperature, thus sufficiently meeting the refrigeration needs for the next hot drink cycle.

[0077] Alternatively, the refrigeration assembly 200 may also include a waste discharge body. The waste discharge body, for example, forms a waste discharge chamber. The waste discharge chamber is connected to the downstream end of the refrigeration channel 212a via a sixth conduit (not shown in the attached diagram). This allows the remaining warm water flowing within the refrigeration channel 212a to directly enter the waste discharge chamber of the waste discharge body via the sixth conduit and be ultimately discharged as waste liquid.

[0078] Of course, when the beverage preparation equipment is pre-installed with, for example, a tray (not shown in the attached diagram), and the tray contains a water collection tank, the tray can directly constitute the aforementioned waste discharge body. The water collection tank then constitutes the waste discharge chamber.

[0079] Based on one or more of the above embodiments, it can be understood that the fifth pipe 550 is designed to be on and off. This allows the fifth pipe 550 to intermittently replenish water to the boiler body 810 according to actual needs. That is, when the boiler body 810 needs water replenishment, the fifth pipe 550 can be controlled to connect the boiler body 810 and the water inlet pipe 710. Conversely, when the boiler body 810 does not need water replenishment, the fifth pipe 550 can be controlled to disconnect the boiler body 810 and the water inlet pipe 710.

[0080] Depending on actual needs, the refrigeration channel 212a and the water inlet pipe 710 can also be made connectable and disconnectable via structures such as valve bodies. Similarly, this allows for intermittent water replenishment to the refrigeration channel 212a as needed. That is, when the refrigeration channel 212a requires water replenishment, the connection between the refrigeration channel 212a and the water inlet pipe 710 can be controlled. Conversely, when the refrigeration channel 212a does not require water replenishment, the connection between the refrigeration channel 212a and the water inlet pipe 710 can be controlled to disconnect.

[0081] Alternatively, depending on actual needs, the cooling channel 212a and the water inlet pipe 710 can remain connected. In this case, the water inlet pipe 710 continuously supplies external cold water to the cooling channel 212a. This ensures that the cold water in the cooling channel 212a remains flowing, guaranteeing that the heat exchange with the hot beverage is always with cooler hot water, rather than lukewarm water that has undergone at least one heat exchange.

[0082] Of course, based on this embodiment, the inlet pipe 710 can be further configured to be directly connected to an external cold water source (e.g., connected to an external faucet). Alternatively, the inlet pipe 710 can be configured to be connected to an inlet chamber (not shown in the attached diagram). This inlet chamber is connected to the external cold water source in a way that allows for switching on and off. The inlet chamber can also be connected to, for example, the outlet end or downstream section of the refrigeration channel 212a. This allows the water (especially the remaining water not connected to the boiler body 810) to circulate between the inlet chamber, the inlet pipe 710, and the refrigeration channel 212a. Because the inlet chamber forms sufficient water storage space, the warm water flowing into the inlet chamber via the refrigeration channel 212a can be sufficiently cooled and turned back into cold water before entering the refrigeration channel 212a again.

[0083] In addition, the beverage preparation system may also include a liquid storage body (not shown in the attached diagram). The liquid storage body forms a liquid storage chamber. The liquid storage chamber is connected to the refrigeration channel 212a and is located upstream of the boiler body 810.

[0084] The liquid storage body can be specifically located at the fifth pipe 550. Of course, the liquid storage body can be connected to the fifth pipe 550 in a way that allows it to be switched on and off. And for ease of understanding, the fifth pipe 550 is divided into an upstream section near the refrigeration body 210 and a downstream section near the boiler body 810.

[0085] When it is necessary to temporarily store the water entering the boiler body 810 via the refrigeration channel 212a, the fifth pipe 550 is connected to the upstream pipe section, while the fifth pipe 550 is disconnected from the downstream pipe section. At this time, the water discharged from the lower outlet end of the refrigeration channel 212a can be connected to the liquid storage chamber.

[0086] When it is necessary to directly utilize the water that enters the boiler body 810 via the refrigeration channel 212a, the fifth pipe 550 can be operated to isolate the upstream pipe section and the downstream pipe section. At this time, the water discharged from the downstream end of the refrigeration channel 212a can flow directly into the boiler body 810 via the fifth pipe 550.

[0087] When it is necessary to utilize the water stored in the storage chamber, the fifth pipe 550 can be operated to disconnect it from the upstream pipe section, while the fifth pipe 550 and the downstream pipe section can be connected. At this time, the water stored in the storage chamber can be connected to the boiler body 810.

[0088] In this scheme, the pump body 720 can be directly installed in the downstream section of the fifth pipeline 550, making it easier to switch between the above-mentioned multiple flow paths with a single pump body 720.

[0089] Next, the outlet end of the boiler body 810 can be connected to the inlet end of the beverage tank 110 through the fourth pipe 540, thereby realizing the purpose of introducing the heated hot water into the beverage tank 110 through the fourth pipe 540.

[0090] As described above, the pump body 720 can be directly installed at the fifth pipe 550. In this way, the same pump body 720 can serve two purposes: driving external cold water into the refrigeration channel 212a and driving warm water in the refrigeration channel 212a into the boiler body 810 via the fifth pipe 550.

[0091] Furthermore, there are various designs for the refrigeration unit 210 that achieve the aforementioned objectives. For example... Figure 5 As shown, in one specific embodiment, the refrigeration body 210 includes an inner tube 211 and an outer tube 212 that are connected internally and externally. The inner tube 211 defines a receiving channel 211a. The outer wall of the inner tube 211 and the inner wall of the outer tube 212 are spaced apart to define a refrigeration channel 212a at the gap.

[0092] In order to enable the cold water in the cooling channel 212a to exchange heat with the hot beverage in the receiving channel 211a, in specific applications, at least the inner tube 211 is made of a thermally conductive material. Furthermore, the thermal conductivity of the inner tube 211 can be set to be relatively high, facilitating more efficient heat transfer from the hot beverage to the cold water.

[0093] It should be noted that the radial cross-sectional shape of the inner tube 211 and / or the outer tube 212 is not limited in this application. For example, its outer contour shape can be, but is not limited to, a perfect circle, an ellipse, other circles, or polygons.

[0094] Therefore, when the inner tube 211 is inserted into the outer tube 212, it can specifically be that the inner tube 211 abuts against the inner wall of one side of the outer tube 212. At this time, the refrigeration channel 212a defined by the outer wall of the inner tube 211 and the inner wall of the outer tube 212 is roughly crescent-shaped.

[0095] Alternatively, the inner tube 211 can be separated between the outer tubes 212, that is, the inner tubes 211 abut against the radial side walls of the outer tubes 212 respectively. In this case, the refrigeration channel 212a defined by the outer wall of the inner tube 211 and the inner wall of the outer tube 212 is roughly two crescent-shaped sections separated circumferentially.

[0096] Alternatively, the inner tube 211 can be suspended within the hollow structure of the outer tube 212, meaning that the outer wall of the inner tube 211 and the inner wall of the outer tube 212 do not contact each other. In this case, the refrigeration channel 212a defined by the outer wall of the inner tube 211 and the inner wall of the outer tube 212 is approximately annular.

[0097] It is understandable that the shape of the cooling channel 212a can significantly affect the specific heat exchange points and efficiency of the cold water on the hot beverage. For example, when the cooling channel 212a is located at a localized position on the circumference of the receiving channel 211a, the hot beverage at that location will primarily undergo relatively direct heat exchange. The remaining hot beverages in the receiving channel 211a, where no cooling channel 212a is located, need to be combined with the cooled hot beverage to achieve cooling.

[0098] Therefore, as Figure 5 As shown, preferably, the inner tube 211 is suspended inside the outer tube 212, and the two together enclose and define a ring-shaped cooling channel 212a, so as to cover the entire circumference of the receiving channel 211a and realize all-round cooling and temperature reduction of hot drinks in the receiving channel 211a.

[0099] The cooling unit 210 is mainly formed by the inner tube 211 and the outer tube 212 connected together. The overall shape of the cooling unit 210 is not limited; it can be, but is not limited to, an elongated shape extending in a certain direction, a labyrinthine shape, etc. Specifically, as shown... Figure 5 In the structure shown, the refrigeration unit 210 is arranged in a spiral shape. This helps to extend the path length of the receiving channel 211a and the refrigeration channel 212a respectively, and also minimizes the space occupied by the refrigeration unit 210 in the horizontal, vertical and longitudinal directions, making the refrigeration unit 210 more compact and facilitating its installation in beverage making machines.

[0100] In a further embodiment, in order to optimize the cooling effect of the cooling unit 210, the wall thickness of the inner tube 211 can be set to be less than the wall thickness of the outer tube 212.

[0101] The wall thickness of the inner tube 211 should be set as small as possible. This can effectively shorten the heat exchange distance between the hot beverage in the receiving channel 211a and the cold water in the cooling channel 212a. This also means that the heat emitted by the hot beverage in the receiving channel 211a can be more easily absorbed by the cold water in the cooling channel 212a.

[0102] Correspondingly, the wall thickness of the outer tube 212 needs to be set to be relatively large. Similarly, by appropriately increasing the wall thickness of the outer tube 212, the heat exchange distance between the cold water in the refrigeration channel 212a and the air in the external environment can be effectively extended. This ensures that the cold water in the refrigeration channel 212a is not significantly affected by the external environment and will not heat up, thus helping to ensure more efficient cooling of the hot drinks in the receiving channel 211a.

[0103] Furthermore, the radial cross-sectional area of ​​the receiving channel 211a is smaller than that of the cooling channel 212a. The radial cross-sectional area of ​​the receiving channel 211a can be reduced by appropriately decreasing the inner diameter of the inner tube 211. This can slow down the flow rate of hot beverages in the receiving channel 211a to some extent, and also increase the total heat exchange area of ​​the same cup of hot beverage in the receiving channel 211a to some extent.

[0104] Correspondingly, the radial cross-sectional area of ​​the refrigeration channel 212a can be increased by appropriately enlarging the inner diameter of the outer tube 212, thereby increasing the difference between the outer diameter of the inner tube 211 and the inner diameter of the outer tube 212. When the radial cross-sectional area of ​​the refrigeration channel 212a is appropriately increased, more cold water can flow through the same radial cross-sectional area. That is, more cold water can be used to exchange heat with hot drinks at the same radial cross-section.

[0105] Furthermore, the thermal conductivity of the material used to make the outer tube 212 is lower than that of the material used to make the inner tube 211. It can be understood that when the thermal conductivity of the material used to make the outer tube 212 is lower, its thermal conductivity decreases, and its insulation performance improves, which helps to prevent excessive heat exchange between the cold water in the refrigeration channel 212a and the air in the external environment. Further, the thermal conductivity of the material used to make the outer tube 212 is no greater than that of air. This effectively isolates the heat exchange between the external air and the cold water in the refrigeration channel 212a.

[0106] Similarly, when the thermal conductivity of the material used to make the inner tube 211 is high, its thermal conductivity is significantly improved, which helps to accelerate the heat exchange between the hot beverage in the receiving channel 211a and the cold water in the cooling channel 212a, so that the hot beverage can be cooled down more quickly.

[0107] In practical applications, the length of the outer tube 212 is not less than the length of the inner tube 211, so that the refrigeration channel 212a completely covers the receiving channel 211a. In this way, the cold water flowing in the refrigeration channel 212a can completely cover the flow path of the hot beverage flowing in the receiving channel 211a, thereby ensuring that the hot beverage in each channel section of the receiving channel 211a has sufficient cold water for effective cooling.

[0108] When the cooling unit 210 performs as follows Figure 5 As the spiral extends, multiple spiral segments are formed, along with bends connecting each pair of adjacent spiral segments. At this point, the bends in the refrigeration unit 210, i.e., the bends connecting the segments, are connected by an arc transition, forming a bend. Compared to setting the bends at right angles or T-angles, bends facilitate smoother flow of hot beverages in the receiving channel 211a and cold water in the refrigeration channel 212a. This prevents excessive collisions between hot beverages or cold water and the pipe walls during flow, which could affect the quality of the final chilled beverage. Furthermore, it avoids excessive residue of hot beverages, especially hot beverages, in the receiving channel 211a, contributing to improved overall chilled beverage preparation quality.

[0109] Similarly, when the refrigeration unit 210 extends spirally as described above, it forms multiple spiral segments and bent connecting segments between each pair of adjacent spiral segments. To prevent loosening between the spiral segments, which could lead to structural instability of the refrigeration unit 210, a further embodiment includes a clamping member in the refrigeration assembly 200. The clamping member connects and fixes the multiple spiral segments of the refrigeration unit 210 arranged sequentially along its axial direction. The clamping member can extend radially along the refrigeration unit 210 to span all spiral segments at the same location. This facilitates a tight connection of the spiral segments using the same clamping member. When the structure of the refrigeration unit 210 remains stable, it helps maintain the smooth flow of hot drinks and cold water within it, thereby improving the stability and reliability of the cooling effect of cold water on hot drinks.

[0110] Based on one or more of the above embodiments, the outlet end of the output pipe 300 further constitutes a beverage outlet 331. The inlet end of the output pipe 300 is connected to the outlet end of the beverage preparation tank 110 and the outlet end of the receiving channel 211a, respectively.

[0111] For ease of understanding, in the following embodiments, the beverage output module is defined as forming a hot beverage flow path from the outlet end of the self-made beverage container 110 to the output pipe 300, and a cold beverage flow path from the outlet end of the self-made beverage container 110 through the cooling body 210 to the output pipe 300.

[0112] Once the hot beverage flow path is opened, the hot beverage prepared in the beverage preparation tank 110 will be directly guided by the output pipe 300 to be discharged out through the beverage outlet 331, forming a hot beverage product.

[0113] Once the cold beverage flow path is opened, the hot beverage in the beverage container 110 enters the receiving channel 211a of the refrigeration unit 210 and is cooled by the refrigeration structure to obtain a cold beverage. The cold beverage is directly guided by the output pipe 300 to be discharged outward through the beverage outlet 331, thus obtaining a cold beverage product.

[0114] When the hot beverage flow path and the cold beverage flow path are simultaneously or sequentially connected, the hot beverage portion prepared in the beverage preparation tank 110 flows through the cold beverage flow path: that is, the hot beverage enters the receiving channel 211a of the refrigeration unit 210, and is refrigerated by the refrigeration structure to become a cold beverage before entering the output pipe 300. The other portion of the hot beverage flows through the hot beverage flow path: that is, the hot beverage directly enters the output pipe 300. In this way, a temperature-controlled beverage product obtained by mixing a portion of hot beverage and a portion of cold beverage can be obtained.

[0115] To further enhance controllability of the hot and cold beverage flow paths, a modified version of the beverage-making system includes an adjustment mechanism. This mechanism, located between the beverage-making component 100, the refrigeration component 200, and the output pipe 300, switches between the hot and cold beverage flow paths, thereby producing hot, cold, and temperature-controlled beverages. This enriches the system's functionality and ensures that cold beverages or temperature-controlled beverages containing cold beverages are not diluted by ice, maintaining a relatively high drinking quality and ultimately enhancing the system's reliability.

[0116] Given the above, the hot beverage flow path and the cold beverage flow path can be completely independent without any intersection, which makes the output of cold and hot beverages basically unaffected by each other. As for the output of temperature-controlled beverages, the mixing operation can be performed outside the whole machine after the hot and cold beverages are output through the beverage outlet 331, outside the output pipeline 300.

[0117] At this time, the beverage dispensing cylinder 110 can have two outlets. The output pipe 300 can also have two outlets. One outlet of the beverage dispensing cylinder 110 and the output pipe 300 are located on the hot beverage flow path. The other outlet of the beverage dispensing cylinder 110 and the output pipe 300 are located on the cold beverage flow path.

[0118] Next, the regulating mechanism may include an opening / closing element. The opening / closing element can control the opening or blocking of the hot beverage flow path. And / or, the opening / closing element can control the opening or blocking of the cold beverage flow path.

[0119] The specific structure of the opening and closing component can vary, and it can be, but is not limited to, various forms of on / off valves, movable covers, or movable plungers. The opening and closing component can independently control the on / off state of any flow path.

[0120] Alternatively, the hot beverage flow path and the cold beverage flow path can partially intersect, meaning that a portion of the flow path is shared, forming a shared flow path segment. The flow path segment of the hot beverage flow path, excluding the shared flow path segment, is the first non-shared flow path segment. The flow path segment of the cold beverage flow path, excluding the shared flow path segment, is the second non-shared flow path segment. The first non-shared flow path segment, the second non-shared flow path segment, and the shared flow path segment are connected.

[0121] It should be noted that, in feasible embodiments, when the hot beverage flow path as a whole constitutes a shared flow path segment, that is, there is no first non-shared flow path segment.

[0122] The regulating mechanism includes a regulating element. The regulating element connects the first non-shared flow path section, the second non-shared flow path section, and the shared flow path section. When the switching valve activates the first non-shared flow path section and the shared flow path section, it is equivalent to activating the hot beverage flow path. When the switching valve activates the second non-shared flow path section and the shared flow path section, it is equivalent to activating the cold beverage flow path.

[0123] The shared flow path segment mentioned above can be formed at any flow path segment of the hot beverage flow path and / or cold beverage flow path.

[0124] In one specific embodiment, at least a portion of the output conduit 300 constitutes the aforementioned common flow path. Specifically, the output conduit 300 includes an output conduit 330 and a first input conduit 310 and a second input conduit 320 connected thereto. The other end of the output conduit 330 defines a beverage outlet 331. The other end of the first input conduit 310 is connected to the outlet end of the beverage dispensing container 110. The other end of the second input conduit 320 is connected to the outlet end of the receiving channel 211a.

[0125] At this point, the output pipe section 330 also constitutes the aforementioned common flow path section. The outlet end of the beverage container 110 and the first input pipe section 310 together constitute the first non-common flow path section. The outlet end of the beverage container 110, the receiving channel 211a, and the second input pipe section 320 together constitute the second non-common flow path section.

[0126] The first input pipe section 310 and / or the second input pipe section 320 are adjustable for on / off switching. Specifically, the aforementioned adjusting element can be provided in the first input pipe section 310 and / or the second input pipe section 320 to achieve adjustable on / off switching of the first input pipe section 310 and / or the second input pipe section 320.

[0127] In the above embodiment, the beverage-making cylinder 110 can have two outlets, so that the hot beverage flow path and the cold beverage flow path are shared only at the output pipe section 330. Alternatively, in a further embodiment, the regulating component includes a first valve body 410. The beverage-making system also includes a first pipe 510 and a second pipe 520, with one end of the first pipe 510, the second pipe 520, and the first input pipe section 310 respectively connected to different valve ports of the first valve body 410. The other end of the first pipe 510 is connected to the outlet of the beverage-making cylinder 110. The other end of the second pipe 520 is connected to the inlet of the receiving channel 211a.

[0128] The first valve body 410 can selectively control the on / off connection between the first pipeline 510 and the second pipeline 520, or between the first pipeline 510 and the first input pipeline 310.

[0129] At this point, not only does the output pipe section 330 constitute the aforementioned common flow path, but the outlet end of the beverage container 110, the first pipe 510, and the first valve body 410 also constitute the aforementioned common flow path.

[0130] Thus, when the first valve body 410 switches, and the first pipe 510 and the first input pipe section 310 are connected, it is equivalent to opening the hot beverage flow path, allowing hot beverages to be output via this path. When the first pipe 510 and the second pipe 520 are connected, it is equivalent to opening the flow path between the outlet end of the beverage-making cylinder 110 and the inlet end of the receiving channel 211a. The hot beverage produced by the beverage-making cylinder 110 can be fed into the receiving channel 211a for cooling by the refrigeration structure.

[0131] Then, the regulating component may further include a second valve body 420. The beverage making system also includes a third conduit 530. One end of the third conduit 530 and the second input conduit 320 are respectively connected to different valve ports of the second valve body 420. The other end of the third conduit 530 is connected to the outlet end of the receiving channel 211a. The second valve body 420 can control the on / off state between the third conduit 530 and the second input conduit 320.

[0132] Thus, with the joint switching of the first valve body 410 and the second valve body 420, when the first pipe 510 and the second pipe 520 are connected, and the third pipe 530 and the second input pipe section 320 are connected, it is equivalent to the cold drink flow path being connected, and cold drinks can be output through the third pipe 530 and the second input pipe section 320.

[0133] After the second valve body 420 is provided as described above, the beverage preparation system further includes a waste discharge pipe 560. One end of the waste discharge pipe 560 is connected to another valve port of the second valve body 420. The other end of the waste discharge pipe 560 is used to connect to an external slag collection structure. The second valve body 420 can control the on / off connection between the third pipe 530 and the waste discharge pipe 560.

[0134] It should be noted that the waste discharge pipe 560 and the slag collection structure can together constitute the aforementioned waste discharge main body. Alternatively, the waste discharge pipe 560 and the slag collection structure can be an additional waste discharge design, distinct from the aforementioned waste discharge main body.

[0135] With the waste discharge pipe 560 and slag collection structure installed, the beverage preparation tank 110 and / or the refrigeration unit 210 can be cleaned as needed.

[0136] In one specific scheme, the fourth pipe 540 between the boiler body 810 and the beverage-making tank 110 can be connected first to introduce hot water from the boiler body 810 into the beverage-making tank 110. At this point, the hot water does not serve a brewing or extraction purpose, but rather cleans the interior of the beverage-making tank 110, removing any residue. Next, the hot water in the beverage-making tank 110 (which can be residual hot water after cleaning the tank, or clean hot water from the boiler body 810) can be connected to the receiving channel 211a through the first pipe 510 and the second pipe 520 (controlled by the first valve 410) to clean the receiving channel 211a. Finally, through the third pipe 530 and the waste discharge pipe 560 (controlled by the second valve 420), the water in the receiving channel 211a is discharged to the slag collection structure via the waste discharge pipe 560.

[0137] Alternatively, in another specific embodiment, a seventh pipeline (not shown in the attached diagram) can be directly established between the boiler body 810 and the receiving channel 211a. This seventh pipeline can be connected to the receiving channel 211a via the first valve body 410 or an additionally provided third valve body (not shown in the attached diagram). In this way, hot water from the boiler body 810 can be directly introduced into the receiving channel 211a for cleaning without passing through the drinking water tank 110. Finally, the hot water is discharged to the slag collection structure via the waste discharge pipeline 560.

[0138] Based on one or more of the above embodiments, further, please refer to... Figure 2 The beverage preparation system also includes an aeration assembly. The aeration assembly is disposed in the hot beverage flow path between the outlet end of the self-made beverage container 110 and the beverage outlet 331, to blow any remaining hot beverage in the hot beverage flow path into the beverage container 110 or outwards via the beverage outlet 331. And / or, the aeration assembly is disposed in the cold beverage flow path between the outlet end of the receiving channel 211a and the beverage outlet 331, to blow any remaining cold beverage in the cold beverage flow path into the receiving channel 211a or outwards via the beverage outlet 331.

[0139] That is, the aeration assembly can be selectively installed in the hot beverage flow path and / or the cold beverage flow path. However, for ease of understanding, the following description will use the aeration assembly installed in the hot beverage flow path as an example. In the embodiments described below, the output pipe 300 of the aeration assembly mainly refers to the first input pipe section 310 and the output pipe section 330. It can be understood that if the aeration assembly is installed in the cold beverage flow path, the following adjustments can be made accordingly.

[0140] The aeration assembly includes an air pump 620 and an air volume regulator 610. The aeration assembly is located in the middle of the output pipe 300 to divide the output pipe 300 into a first section connecting to the beverage dispensing tank 110 and a second section defining the beverage outlet 331. In practical applications, the second section may include portions of the first input section 310 and the output section 330.

[0141] The aeration component typically starts operating after the machine has completed one or more beverage preparation and output operations. At this time, the air pump 620 starts operating according to the air volume value preset by the air volume regulator 610 to discharge the residual liquid in the second pipe section (for ease of understanding, this process is defined as the liquid drainage operation below).

[0142] In other words, the air pump 620 starts operating under the control of the air volume regulator 610, driving external gas into the output pipe 300 and flowing at least along the second pipe section. During the flow of the external gas in the second pipe section, it can blow out any liquid remaining in the second pipe section. Furthermore, during this drainage operation, the external gas can also dry and ventilate the output pipe 300 to remove odors, ensuring a drier and cleaner internal environment, which helps improve the quality of subsequent beverages.

[0143] First, it should be noted that, through structural design, the air pump 620 described above can drive gas only into the second pipe section, thereby pushing the residual liquid in the second pipe section outward. At this point, before the air pump 620 starts operating, for example, by disconnecting the connection between the inlet end of the output pipe 300 and the outlet end of the beverage container 110, the gas can essentially not flow through the first pipe section and can only enter the second pipe section.

[0144] Alternatively, the air pump 620 described above can drive gas into the first pipe section and the second pipe section respectively, thereby pushing the residual liquid in the first pipe section and the second pipe section outward. Specifically, when the inlet end of the output pipe 300 and the outlet end of the beverage container 110 are kept connected, the residual liquid in the first pipe section will be pushed back into the beverage container 110.

[0145] Therefore, based on the above, it is important to emphasize that the aforementioned drainage operation does not constitute a specific limitation on its application. That is, the purpose of the air pump 620 driving gas to discharge the residual liquid in the output pipeline 300 (the first and / or second pipeline section) can be waste disposal. In this case, the residual liquid constitutes waste liquid and is essentially discarded.

[0146] In a specific application, the beverage outlet 331 can be kept open after the beverage preparation and output operation is completed. In this way, at least the liquid remaining in the second pipe section will be directly discharged outward through the beverage outlet 331 under the push of the gas driven by the air pump 620, thus completing the waste discharge.

[0147] In another specific application, the beverage preparation system also includes a waste discharge branch. One end of the waste discharge branch is detachably connected to the middle section of the second pipe segment. The other end of the waste discharge branch forms a waste discharge port. The waste discharge port can be left open, or it can be connected to an external source, such as a water collection tank, to collect waste liquid. After the beverage preparation and output operation is completed, the waste discharge branch and the second pipe segment are connected. In this way, at least the liquid remaining in the second pipe segment will be propelled by the gas driven by the air pump 620 into the waste discharge branch and finally discharged through the waste discharge port, completing the waste discharge process.

[0148] It should be noted that the above-mentioned waste discharge branch can be the waste discharge pipe 560 as described above, or it can be another waste discharge structure design that is different from the waste discharge pipe 560.

[0149] Alternatively, the purpose of the air pump 620 driving gas to discharge the residual liquid in the output pipe 300 can also be recycling. In this case, the residual liquid is, for example, pushed back into the return beverage tank 110. The liquid returned to the beverage tank 110 can be used in the next beverage production and output operation. However, generally, the liquid returned to the beverage tank 110 is also cleaned up during the sludge removal and cleaning operations of the beverage tank 110.

[0150] Alternatively, the purpose of the air pump 620 driving gas to expel residual liquid from the output pipe 300 can also be for beverage dispensing. In this case, this drainage operation generally follows the beverage preparation and dispensing operation. The residual liquid is pushed to the beverage outlet 331 and ultimately into the external container that receives the beverage. In this way, the amount of beverage residue in the output pipe 300 is effectively reduced after each beverage preparation and dispensing operation, ensuring that the amount of beverage liquid in each external container is more in line with the target amount, thus achieving more precise beverage preparation.

[0151] In a specific application, it can also be set so that the beverage outlet 331 remains open after the beverage preparation and output operation is completed. In this way, at least the liquid remaining in the second pipe section will be directly discharged outward through the beverage outlet 331 and into the external container under the push of the gas driven by the air pump 620.

[0152] Furthermore, the air volume can be appropriately set using the air volume regulator 610. At this air volume, the air pump 620 drives sufficient gas to completely push out the residual liquid in the second pipe section. This eliminates the residual liquid in the second pipe section while preventing excessive gas discharge, thus avoiding splashing, foaming, or other contamination caused by the residual liquid.

[0153] To achieve the above objectives, the gas volume regulator 610 can be specifically embodied as a flow regulating valve, a pressure regulating valve, etc. Once the preset gas volume value is determined, the air pump 620 will operate according to the preset gas volume value, thereby inputting the preset gas volume value into the output pipeline 300, so that the gas remaining in the second pipeline section can be pushed out as precisely as possible.

[0154] Of course, the aforementioned air volume regulator 610 may also specifically include a regulator body and an operating part exposed outside the casing of the whole machine. The operating part can be manually operated by the user, thereby defining different air volume values ​​during operation, so that the air volume value of the gas driven into the second pipe section by the air pump 620 can be flexibly adjusted, thereby making the air drive component adaptable to more application scenarios.

[0155] Please also see Figure 2 To minimize the amount of liquid remaining in the output pipe 300 and expel it, the aeration assembly can be positioned as close as possible to the outlet end of the beverage container 110 in practical applications. This means the length of the first pipe section is significantly shorter than the length of the second pipe section. Consequently, the second pipe section constitutes a larger proportion of the total length of the output pipe 300, and the liquid mainly remains in the second pipe section. When the air pump 620 drives gas into the second pipe section, it pushes the remaining liquid outwards, thus significantly reducing the amount of liquid remaining in the entire output pipe 300.

[0156] The aforementioned air-driving component can be directly installed at the output pipe 300. Alternatively, in a specific embodiment, the air-driving component may also include an air-driving branch. One end of the air-driving branch is connected to the middle section of the output pipe 300. The other end of the air-driving branch is used for installing the air pump 620 and the air volume regulator 610. The air-driving branch can be installed at any location on the output pipe 300 as needed. Furthermore, the size, shape, and material of the air-driving branch itself can be specifically configured according to actual requirements.

[0157] The air drive branch can place the air pump 620 and the air volume regulator 610 in a suitable location and separate them from the output pipeline 300, so that the routing of the output pipeline 300 and the layout of the air pump 620 and the air volume regulator 610 are basically independent of each other.

[0158] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
