Abstract
Description
Technical Field
[0001] This invention belongs to the field of coffee machine technology, specifically relating to a multi-position extraction coffee machine and its control method. Background Technology
[0002] Currently, coffee machines and water dispensers are mostly sold as independent devices, developing their technologies based on their respective functions. Coffee machines typically contain an independent water tank, heating system, brewing mechanism, and other structures or devices. Their workflow generally involves filling the water tank with clean water, heating it to a suitable temperature using a heating element, and then allowing it to flow through coffee grounds via pump pressure or gravity for extraction, ultimately yielding coffee liquid. On the other hand, water dispensers are mainly divided into bottled water dispensers and piped (direct drinking) dispensers. Both types of water dispensers are equipped with a water tap or switch and a drip tray.
[0003] However, this separation of coffee machines and water dispensers has increasingly revealed a series of technical defects and user pain points in practical applications, mainly in the following aspects: 1. Large space occupation and poor layout flexibility. Two separate devices require corresponding countertop or floor space. In the limited living space of a family kitchen, apartment countertop, or in a space-constrained office workstation or reception area, placing two devices side by side often looks cramped, affecting the overall space utilization efficiency and aesthetics. Users often need to accommodate coffee machines and their accessories (coffee beans, capsules, cups), water dispensers and their water buckets or water purification components in a limited area, resulting in a cluttered operating area and limiting the planning of other functional spaces.
[0004] 2. High Purchase and Maintenance Costs. Users need to purchase two separate, independently functioning devices, resulting in a significantly higher overall purchase cost compared to a single device. Maintenance costs also increase accordingly. For example, regular cleaning and descaling of the water tanks and pipes of both the coffee machine and water dispenser are required, along with cleaning, maintenance, and repair of the heating and cooling systems. Furthermore, the electricity supply is also split, increasing energy consumption over time.
[0005] 3. Cumbersome operation and fragmented user experience. Users need to manage the water supply for two devices separately. For example, changing the water tank or adding drinking water to the water tank of the coffee machine and water dispenser are done separately, and the water supply or coffee making is done at different locations, resulting in a disjointed operation process.
[0006] Therefore, there is an urgent need to develop an all-in-one machine that integrates the functions of a water dispenser and a coffee machine to meet market demand. Summary of the Invention
[0007] One of the objectives of this invention is to disclose a multi-position coffee extraction machine that integrates water dispensing and coffee extraction functions into one machine.

[0049] In one embodiment, the second extraction component 16 is used to deliver extraction solvent to coffee raw materials, and the second extraction component 16 is connected to the outlet of the second heating component 23, which is used to heat the extraction solvent. The extraction solvent heated by the second heating component 23 is delivered to the second extraction component 16.
[0050] In one embodiment, the second extraction component 16 is used to deliver extraction solvent to the coffee raw material, and the second extraction component 16 is connected to the outlet of the first heating component 5, which heats the extraction solvent. The heated extraction solvent is then delivered to the second extraction component 16. In this embodiment, when the first and second extraction components perform hot extraction, the heated extraction solvent is provided by the first heating component, enabling the first and second extraction components to perform hot extraction or cold extraction simultaneously.
[0051] In one embodiment, the second extraction component 16 is used to deliver extraction solvent to coffee raw materials, and the second extraction component 16 is connected to the outlets of the second heating component 23 and the first heating component 5. The second heating component 23 and the first heating component 5 are used to heat the extraction solvent, and the extraction solvent heated by the second heating component 23 and the first heating component 5 is delivered to the second extraction component 16.
[0052] In this embodiment of the multi-position extraction coffee machine, the first heating component 5 is combined with the first extraction component 1. The first heating component 5 independently provides heated extraction solvent to the first extraction component 1, enabling precise temperature control of the extraction solvent. In use, the independent first heating component 5 can provide precise and rapid heating and constant temperature control specifically for coffee extraction by the first extraction component 1, ensuring that the extraction solvent penetrates the coffee powder at the optimal temperature, thereby extracting coffee with a rich aroma and balanced taste.
[0053] In this embodiment of the multi-position extraction coffee machine, the second heating component 23 is combined with the second extraction component 16.

This not only solves the problems of large footprint, high purchase and maintenance costs, and cumbersome operation and management of traditional independent coffee machines and water dispensers, but also enables simultaneous dispensing of hot water and coffee making.

In one embodiment, the second heating component 23 and the first heating component 5 provide heated extraction solvent to the second extraction component 16 and the first extraction component 1, respectively, so that the first extraction component 1 and the second extraction component 16 can simultaneously perform hot coffee extraction operations. That is, the operator can make two cups of hot coffee drinks at the same time, which effectively improves coffee making efficiency and increases the number of cups of coffee made per unit time. This makes this multi-position extraction coffee machine suitable for some scenarios with high coffee demand, such as offices, convenience stores, etc. Of course, it can also be used at home.
[0057] In this embodiment, the multi-position extraction coffee machine includes a first extraction component 1, a second extraction component 16, a first heating component 5, a water dispensing component 24, and a second heating component 23. The second heating component 23 is independently configured from the first heating component 5, and the independent configuration of the second heating component 23 and the first heating component 5 provides heated hot water or extraction solvent to the water dispensing component 24 and the first extraction component 1, respectively. The second heating component 23 is also connected to the second extraction component 16, realizing the integration of coffee machine functions and water dispenser functions into one device, directly solving the problems mentioned in the background art such as large footprint, high purchase and maintenance costs, and cumbersome operation and management of traditional independent coffee machines and water dispensers.
[0058] This multi-station coffee maker integrates coffee and water dispenser functions, allowing for simultaneous coffee and water dispensing, or the preparation of two beverages at the same time. This makes it particularly suitable for compact offices, small home kitchens, or hotel rooms. Users only need to purchase and install it once, and maintenance is limited to cleaning and water supply to a single unit, reducing long-term complexity and total cost of ownership. Users can easily switch between coffee and water dispensing from a single workstation, with a seamless workflow that greatly enhances convenience and user experience.
[0059] In this embodiment of the multi-position coffee extraction machine, the coffee making and water dispensing functions are independently modularized, with each module having its own independent heating component. These two independent modules are highly integrated within the machine's body. This not only effectively solves the space, cost, and operational pain points caused by separating the coffee machine and water dispenser, but also, through the independent design of the first heating component 5 and the second heating component 23, professionally balances and improves the hygiene, efficiency, and experience of coffee extraction quality and water supply, achieving an integrated innovation effect of "1+1>2". In this embodiment of the multi-position coffee extraction machine, the first extraction component 1 and the second extraction component 16 are also connected to the first heating component 5 and the second heating component 23 respectively, resulting in two independent coffee extraction modules. This ensures that each coffee extraction module can work independently and efficiently, while effectively solving the space, cost, and operational pain points caused by separating multiple coffee machines.
[0060] In this embodiment, the extraction solvent is used to extract concentrated coffee from coffee raw materials. The extraction solvent is generally purified water, mineral water, or other water-based solutions, such as aqueous solutions containing ethanol, milk, or fruit juice.
[0061] In one embodiment, the extraction solvent is drinking water, which includes, but is not limited to, purified water or mineral water.
[0062] In one embodiment, the first heating component 5 includes a first heater.
[0063] In one embodiment, the first heater is a storage heater, such as a boiler heater. Storage heaters have a large water storage capacity, storing and maintaining the heated water in the heater for later use. Storage heaters have low material and operating costs, low maintenance costs, and can provide a large water flow when drawing water, making them suitable for locations with a high demand for hot water in a short period.
[0064] In one embodiment, the first heater is a cast aluminum electric heater, which has the advantages of long life, good heat preservation performance, strong mechanical properties, corrosion resistance, and magnetic field resistance.
[0065] In one embodiment, the first heater is a thick-film heater. Thick-film heaters are a common and technologically mature type of heater in the prior art. They typically form a resistance heating circuit by printing and sintering a thick film (metal paste) onto the surface of an insulating substrate (such as stainless steel or ceramic tube), thereby achieving efficient conversion of electrical and thermal energy. Thick-film heaters have a very compact structure, usually appearing as a slender metal tube, a coil, or a flat substrate. During heating, the water to be heated is directly heated as it flows through the channel with the thick-film resistor, requiring no water storage or preheating, achieving "heating live water instantly." Thick-film heaters also have precise temperature control capabilities. Combined with a highly sensitive temperature sensor and microprocessor, the heating power of the thick-film heater can be modulated at the millisecond level, achieving temperature control of ±1℃ or even more precise. In this embodiment, the first heating component 5 uses a thick-film heater, enabling rapid heating and precise temperature control of the water used for coffee extraction.
[0066] The first heater uses a thick-film heater, which minimizes its impact on the temperature field inside the multi-position extraction coffee machine. The thick-film heater's "low thermal inertia" and "high transient response" characteristics ensure no heat diffusion to the surrounding environment after installation, creating a safety barrier for surrounding precision structural components and allowing for flexible placement of components within the surrounding environment. In this multi-position extraction coffee machine, the use of a thick-film heater for the first heater prevents heat diffusion and heat pollution to the refrigeration components, allowing the ice produced in the ice-making component 40 to be stored for a longer period, avoiding rapid melting. This also ensures that the low-temperature cold water stored in the cold water tank 30 remains at a low temperature for a longer period, preventing rapid heating of the cold water within the tank.
[0067] In one embodiment, the second heating component 23 includes a second heater.
[0068] In some embodiments, the second heater is a water storage heater, such as a boiler heater. The use of a water storage heater as the second heater is suitable for locations where a large flow of warm drinking water is required in a short period of time, such as conference rooms or event venues.
[0069] In one embodiment, the second heater is a cast aluminum electric heater, which has the advantages of long life, good heat preservation performance, strong mechanical properties, corrosion resistance, and magnetic field resistance.
[0070] In one embodiment, the second heater is a thick-film heater. The use of a thick-film heater allows users to obtain a better taste when using drinking water to brew tea, such as at 85°C for brewing tea, or at 95°C for extracting coffee, by instantly obtaining hot water at the required temperature with a faster response.
[0071] Furthermore, the use of a thick-film heater for the second heater minimizes its impact on the temperature field within the multi-position extraction coffee machine. The thick-film heater's low thermal inertia and high transient response characteristics ensure no heat diffusion to the surrounding environment after installation, creating a safety barrier for surrounding precision structural components and allowing for flexible placement of components within the surrounding environment. In this multi-position extraction coffee machine, the use of a thick-film heater for the second heater prevents heat diffusion and heat pollution to the refrigeration components. This allows the ice produced in the ice-making component 40 to be stored for a longer period, avoiding rapid melting, and ensures that the low-temperature water stored in the cold water tank 30 remains at a low temperature for an extended period, preventing rapid heating of the cold water within the tank.
[0072] In one embodiment, both the first heater and the second heater are thick-film heaters. No insulation layer is required outside the thick-film heater. The thick-film heater causes no heat pollution or heat radiation to the surrounding environment and has little impact on the refrigeration components in the multi-position extraction coffee machine, thus avoiding rapid heating of ice and low-temperature cold water stored in the multi-position extraction coffee machine.
[0073] In one embodiment, please refer to Figure 1 In a multi-position coffee maker, the water source component 20 includes a water tank configured to store purified water that is safe to drink directly. The purified water includes, but is not limited to, purified water or mineral water.
[0074] In one embodiment, the water tank is connected to the second heating component 23 and is configured to provide drinking water to the second heating component 23. The water tank is also connected to a drinking water component 24 and is configured to provide drinking water to the drinking water component 24. The water tank contains purified water that is safe to drink directly. When connecting to drinking water, if the purified water in the water tank enters the second heating component 23, the purified water is heated by the second heating component 23 to obtain hot water, which is then discharged from the drinking water component 24. This enables the multi-position extraction coffee machine to provide hot water for drinking, achieving a direct drinking hot water mode. Alternatively, if the purified water in the water tank is discharged directly from the drinking water component 24 without passing through the second heating component 23, the multi-position extraction coffee machine can provide room temperature water, achieving a direct drinking room temperature water mode.
[0075] In one embodiment, please refer to Figure 1 The water tank is connected to the first heating element 5 and is configured to provide water flow to the first heating element 5. The water tank is also connected to the first extraction element 1 and is configured to provide extraction water flow to the first extraction element 1. Furthermore, the water tank is connected to the second heating element 23 and is configured to provide extraction water flow to the second heating element 23. Finally, the water tank is connected to the second extraction element 16 and is configured to provide extraction water flow to the second extraction element 16.
[0076] The water tank is filled with potable purified water. The water tank is configured to provide extraction water to the first extraction assembly 1. During coffee making, the purified water from the tank enters the first heating assembly 5, where it is heated to obtain hot water suitable for coffee extraction. This hot water is then output through the first extraction assembly 1 to the portafilter basket in the portafilter, extracting the coffee grounds and achieving the hot extraction function of this multi-position extraction coffee machine. Alternatively, if the purified water from the tank bypasses the first heating assembly 5 and enters the first extraction assembly 1 directly, the first extraction assembly 1 outputs room-temperature purified water from the tank. This room-temperature water is then output through the first extraction assembly 1 to the portafilter basket in the portafilter, extracting the coffee grounds and achieving the room-temperature extraction function of this multi-position extraction coffee machine. Room-temperature extraction is a special case of low-temperature or cold extraction.
[0077] The water tank is filled with potable water. The water tank is configured to supply extraction water to the second extraction assembly 16. During coffee making, the water in the tank enters the second heating assembly 23, where it is heated to obtain hot water suitable for coffee extraction. This hot water is then output through the first extraction assembly 1 to the portafilter basket in the extraction port, thus extracting the coffee grounds and realizing the hot extraction function of this multi-position espresso machine.
[0078] In the aforementioned embodiments, by adding a water tank to the multi-position coffee maker, which supplies water to the second heating element 23 and the first heating element 5, as well as to the first extraction element 1 and the second extraction element 16, and to the drinking water element 24, the adaptability of the multi-position coffee maker is improved. This allows the multi-position coffee maker to be installed in any location without needing to use tap water or bottled water, reducing the need for piping connections to external water sources and avoiding dependence on external water sources, thus increasing the range of applications for the multi-position coffee maker. Furthermore, adding a water tank filled with and storing directly drinkable purified water provides sufficient water pressure and a large water flow for coffee making or drinking water, ensuring stable water pressure and adjustable water flow.
[0079] In one embodiment, the water tank is located at the rear of the multi-position extraction coffee machine, and the volume of the water tank is maximized to allow for more purified water storage, provided that the space inside the multi-position extraction coffee machine permits.
[0080] In one embodiment, the water tank is detachably connected to the body of the multi-position coffee extraction machine. When adding water to the water tank, the water tank can be removed and moved to the water filling position to collect water, making it highly versatile.
[0081] In one embodiment, the water tank is equipped with a water inlet, to which a water inlet pipe is connected. The other end of the water inlet pipe is connected to the purified water outlet of a filter connected to the tap water pipe. Water is replenished to the water tank through the tap water pipe. This replenishment method eliminates the need for frequent manual refilling by the user, resulting in a better user experience. The purified water obtained after filtration must meet the standards for direct drinking water. Of course, in some embodiments, the other end of the water inlet pipe connected to the water tank can also be directly connected to a bottled drinking water dispenser.
[0082] In one embodiment, a water level sensor is installed on the water tank to detect the water level in the tank. The water temperature sensor is electrically connected to the controller 50 in the multi-position extraction coffee machine, which can realize water level alarm to remind the user to add water or automatically add water through the tap water source to ensure timely water replenishment.
[0083] In one embodiment, the water tank is also provided with a water level connector and a water level switch 27. The water level switch 27 has a high water level switch 27 and a low water level switch 27. The water level connector triggers the high water level switch 27 or the low water level switch 27 to start, thereby turning off the automatic water replenishment operation to the water tank or starting the automatic water replenishment operation to the water tank, thus realizing the automatic water replenishment operation.
[0084] In one embodiment, the water source component 20 can be a structure that combines a municipal tap water pipe with a direct drinking filter. It supplies water through the municipal tap water and filters it through the direct drinking filter to obtain the required purified water, which directly supplies water to the drinking water component 24, the first extraction component 1, the second extraction component 16, the first heating component 5 and the second heating component 23, thus avoiding the need for water replenishment.
[0085] In one embodiment, a first pipe 11 is connected to the outlet of the water tank, and a first pump body 3 is installed on the first pipe 11. The first pump body 3 is configured to supply extraction water to the first extraction assembly 1. A first three-way control valve 4 is connected to the end of the first pipe 11, and one outlet of the first three-way control valve 4 is connected to the first heating assembly 5. A second pipe 12 is connected to the other outlet of the first three-way control valve 4, and the other end of the second pipe 12 is connected to the inlet of the first extraction assembly 1. The second pipe 12 is arranged in parallel with the first heating assembly 5.
[0086] In this embodiment, a first pump body 3 is provided on the first pipeline 11, and the end of the first pipeline 11 is connected to a first three-way control valve 4. One outlet of the first three-way control valve 4 is connected to the inlet of the first heating component 5. The first pipeline 11 supplies water to the first heating component 5. The hot water obtained after being heated by the first heating component 5 enters the first extraction component 1 to realize the hot extraction function of this multi-position extraction coffee machine.
[0087] During the hot extraction process, water flows through the first heating element 5, which rapidly heats the water to 95°C. The water then passes through the first extraction element 1 and is output to the extraction portafilter, thus achieving hot coffee extraction. The first heating element 5 heats the water to 95°C for hot coffee extraction, resulting in excellent extraction quality. The coffee made from the extracted concentrate has a superior taste and is free of bitterness.
[0088] In this embodiment, a first pump body 3 is installed on the first pipeline 11, and a first three-way control valve 4 is installed on the first pipeline 11. The first three-way control valve 4 is connected to the outlet of the first pump body 3, and a second pipeline 12 is connected to the other outlet of the first three-way control valve 4. The other end of the second pipeline 12 is connected to the inlet of the first extraction component 1. The second pipeline 12 is arranged in parallel with the first heating component 5. The water flow transported by the first pipeline 11 is directly delivered to the position of the first extraction component 1 through the first pump body 3 and the first three-way control valve 4, and discharged from the first extraction component 1 into the extraction handle to achieve room temperature coffee extraction.
[0089] In this embodiment, room-temperature drinking water from the water tank is directly supplied to the first extraction component 1 to achieve room-temperature extraction, or cold extraction, of the coffee raw material at the first extraction component 1. Room-temperature water extraction is one of the standard methods for making cold brew coffee. This low-temperature extraction method can effectively avoid the bitterness and acidity caused by high temperatures, thereby extracting a coffee liquid with a milder flavor, more prominent sweetness, and lower acidity.
[0090] In some embodiments, to accelerate the efficiency of room temperature water extraction, a booster valve or back pressure valve is installed on the second pipeline 12. The booster valve or back pressure valve increases the water pressure of the room temperature water flowing through the second pipeline 12, thereby accelerating the extraction efficiency and shortening the extraction time.
[0091] In one embodiment, the first pump body 3 is an electromagnetic pump. Electromagnetic pumps are small in size and offer high control precision. They directly drive fluid through electromagnetic force, eliminating mechanical moving parts and overcoming many limitations of traditional mechanical pumps. This fundamentally eliminates mechanical wear, enabling maintenance-free or low-maintenance operation and significantly improving the reliability and lifespan of the equipment. The electromagnetic pump has a high output pressure, allowing the water flow from the first pump body 3 to smoothly pass through the first heating element 5 and enter the first extraction element 1, or directly enter the first extraction element 1 without passing through the first heating element 5, thus improving extraction efficiency. In other embodiments, the first pump body 3 may also be an impeller pump, a plunger pump, or a peristaltic pump.
[0092] In one embodiment, the first three-way control valve 4 is a three-position three-way solenoid valve. The first three-way solenoid valve is electrically connected to the controller 50 of the multi-position extraction coffee machine to realize the automatic control of the first three-way solenoid valve. It automatically opens the inlet and one of the outlet passages of the first three-way solenoid valve as needed, or closes the first three-way control valve 4 itself, realizing the automatic switching between hot extraction mode and low temperature cold extraction mode.
[0093] In one embodiment, a seventh pipe 13 is connected to the outlet of the first heating component 5. A third three-way control valve 6 is installed on the seventh pipe 13. The inlet of the third three-way control valve 6 is connected to the seventh pipe 13, and one outlet of the third three-way control valve 6 is connected to the first extraction component 1. The other outlet of the third three-way control valve 6 is open to the atmosphere.
[0094] In one embodiment, the third three-way control valve 6 is a three-position three-way solenoid valve.
[0095] In this embodiment, the hot water obtained by heating the first heating component 5 passes through the third three-way control valve 6 and finally enters the first extraction component 1 to achieve coffee extraction. If the first extraction component 1 experiences blockage or other problems that prevent the water flow from being discharged smoothly, the inlet to the outlet connected to the atmosphere of the third three-way control valve 6 is immediately opened, allowing the water output from the first heating component 5 to be discharged through the third three-way control valve 6, thus achieving pressure relief.
[0096] In one embodiment, the first extraction component 1 includes a first brewing head. The second extraction component includes a second brewing head.
[0097] In one embodiment, the outlet of the third three-way control valve 6, which is connected to the atmosphere, is generally connected to the wastewater box 7, which is also connected to the atmosphere.
[0098] In one embodiment, a pressure relief valve 15 is also connected to the outlet of the first pump body 3, and the outlet of the pressure relief valve 15 is connected to the wastewater box 7.
[0099] In one embodiment, an eighth pipe 14 is connected to the outlet of the first heating component 5. A first two-way control valve 8 is installed on the eighth pipe 14. The inlet of the first two-way control valve 8 is connected to the eighth pipe 14, and the outlet of the first two-way control valve 8 is connected to a steam nozzle 2, which is used to output steam. The water flow delivered by the first pump body 3 enters the first heating component 5, which heats the water flow to a steam state. Then, the water flow is delivered to the steam nozzle 2 through the eighth pipe 14 and the first two-way control valve 8, and the steam nozzle 2 outputs steam. The high-temperature steam obtained by the first heating component 5 is discharged through the steam nozzle 2 to brew milk or prepare milk foam, enabling this multi-position extraction coffee machine to prepare coffee with a wider variety of flavors.
[0100] In one embodiment, the first two-way control valve 8 is a two-position two-way control valve. The first two-way control valve 8 is electrically connected to the controller 50 of the multi-position extraction coffee machine to realize the automatic control of the first two-way control valve 8 and realize the automatic switching control of the on and off of the first two-way control valve 8.
[0101] In one embodiment, a third pipe 21 is connected to the outlet of the water tank. A second pump body 25 is installed on the third pipe 21, and the second pump body 25 is configured to supply drinking water to the drinking water assembly 24. A second three-way control valve 22 is installed on the third pipe 21, and one outlet of the second three-way control valve 22 is connected to the second heating assembly 23. A fourth pipe 26 is connected to the other outlet of the second three-way control valve 22, and the other end of the fourth pipe 26 is connected to the drinking water assembly 24. The fourth pipe 26 is arranged in parallel with the second heating assembly 23.
[0102] In this embodiment, a second pump body 25 is provided on the third pipeline 21, and a second three-way control valve 22 is provided on the third pipeline 21. The second three-way control valve 22 is connected to the outlet of the second pump body 25, and one outlet of the second three-way control valve 22 is connected to the inlet of the second heating component 23. The third pipeline 21 supplies water to the second heating component 23, and the hot water obtained after being heated by the second heating component 23 enters the drinking water component 24, thereby realizing the direct drinking hot water function of this multi-position extraction coffee machine.
[0103] In this embodiment, a second pump body 25 is installed on the third pipeline 21. The end of the third pipeline 21 is connected to a second three-way control valve 22. A fourth pipeline 26 is connected to the other outlet of the second three-way control valve 22. The other end of the fourth pipeline 26 is connected to the inlet of the drinking water assembly 24. The fourth pipeline 26 is arranged in parallel with the second heating assembly 23. The water flowed by the third pipeline 21 is directly delivered to the drinking water assembly 24 through the second pump body 25, the second three-way control valve 22, and the fourth pipeline 26, without passing through the second heating assembly 23, thus realizing the function of direct drinking room temperature water.
[0104] In other embodiments, the second pump body 25 may be an impeller pump or a plunger pump, which delivers a large water flow.
[0105] In one embodiment, the second three-way control valve 22 is a three-position three-way solenoid valve. The second three-way solenoid valve is electrically connected to the controller 50 of the multi-position extraction coffee machine to realize the automatic control of the second three-way solenoid valve, automatically opening the inlet and one of the outlet passages of the second three-way solenoid valve as needed, realizing the automatic switching between direct drinking hot water mode and direct drinking room temperature water mode.
[0106] In one embodiment, the drinking water assembly 24 includes a first water outlet 241 and a second water outlet 242. The first water outlet 241 is connected to the second heating assembly 23. The first water outlet 241 is configured to output heated drinking water, and the second water outlet 242 is configured to output unheated drinking water.
[0107] In one embodiment, the end of the fourth pipe 26 furthest from the second three-way control valve 22 is connected to the second outlet 242. The water flow obtained after being heated by the second heating component 23 is output from the first outlet 241. To facilitate the control of the first outlet 241 and the second outlet 242, or due to the need for pipe connection, control valves, such as two-position two-way solenoid valves, can be installed as needed to control the water output of the first outlet 241 and the second outlet 242.
[0108] One end of the fourth pipe 26 is connected to the second three-way control valve 22, and the other end is connected to the second water outlet 242, so that this multi-position extraction coffee machine can simultaneously accept room temperature drinking water and hot brew coffee, or simultaneously accept room temperature drinking water and cold brew coffee, or simultaneously accept room temperature drinking water and brew milk, etc., that is, the coffee mode and water mode of this multi-position extraction coffee machine can be started and worked at the same time.
[0109] The first water outlet 241 is connected to the second heating component 23, so that this multi-position extraction coffee machine can simultaneously draw hot water and brew hot or cold coffee or make milk with the first extraction component 1. That is, the coffee mode and water mode of this multi-position extraction coffee machine can be started and work at the same time.
[0110] In one embodiment, a ninth pipe 18 is also connected to the outlet of the second heating component 23. A second two-way control valve 17 is provided on the ninth pipe 18. The outlet of the second two-way control valve 17 is connected to the second extraction component 16 to supply extraction water to the second extraction component 16.
[0111] In this embodiment, the water flow through the second pump body 25 passes sequentially through the second three-way control valve 22 and the second heating component 23, i.e., the third pipeline 21 supplies water to the second heating component 23. The hot water obtained after being heated by the second heating component 23 enters the second extraction component 16 through the second two-way control valve 17, and is used by the second extraction component 16 to perform hot extraction of coffee, thereby realizing the hot extraction coffee mode of the second extraction component 16 of this multi-position extraction coffee machine.
[0112] It is worth noting that a control valve, such as a two-way solenoid valve, can be installed on the pipeline connected to the first water outlet 241 as needed. This valve can be used to control the first water outlet 241 to close or open when the second extraction component 16 is performing hot coffee extraction. When the first water outlet 241 is open, hot water is supplied and the second extraction component 16 operates simultaneously, thus simultaneously realizing the direct drinking hot water mode of the water dispensing component 24 and the hot coffee extraction mode of the second extraction component 16.
[0113] When the second heating element 23 is working, the water dispensing element 24 can simultaneously receive hot water, and the second extraction element 16 can simultaneously perform hot coffee extraction. At the same time, the first heating element 5 can also be activated, allowing the first extraction element 1 to extract coffee hot or the steam nozzle 2 to dispense steam for milk. Alternatively, if the first heating element 5 is not working, the first extraction element 1 can perform cold coffee extraction. In other words, in this multi-position coffee maker, the first extraction element 1, the second extraction element 16, and the water dispensing element 24 can all work simultaneously, allowing for the extraction of two cups of coffee and the dispensing of drinking water at the same time.
[0114] In one embodiment, a flow meter 9 is installed on the first pipeline to obtain the flow rate of water entering the first body.
[0115] In one embodiment, a multi-position coffee extraction machine includes a refrigeration component, which includes an ice-making component 40. The ice-making component 40 includes an ice-making mechanism and an ice storage box 41, and an ice dispensing component is connected to the ice storage box 41.
[0116] By adding an ice-making component 40 to the multi-position coffee maker, ice cubes are prepared, giving the multi-position coffee maker the function of an ice maker. The prepared ice cubes can be used to prepare beverages of various temperatures or textures. Ice cubes can be added to various desired beverages to obtain a variety of iced drinks, such as iced coffee, iced juice, iced water, etc. This makes the multi-position coffee maker more versatile, suitable for home or office settings, and meets the diverse and multifunctional requirements of users.
[0117] In one embodiment, the ice-making mechanism includes a semiconductor thermoelectric cooler, which has advantages such as small size, low noise, and no vibration. During ice making, one side (cold end) of the thermoelectric module of the semiconductor thermoelectric cooler is tightly attached to the bottom of the water storage container or ice cube mold. Then, when energized, the cold end begins to continuously absorb heat, "transferring" the heat of the water in the water storage container or ice cube mold to the hot end. The hot end continuously dissipates heat through a heat dissipation structure such as a cooling fan. In this way, the water temperature in the water storage container or ice cube mold attached to the cold end gradually drops below the freezing point and begins to freeze, thus obtaining ice cubes. Finally, the ice cubes in the water storage container or ice cube mold are transported to the ice cube storage box 41 by a certain means, such as moving the water storage container or ice cube mold above the ice cube storage box 41 and applying pressure to the back of the water storage container or ice cube mold to push the ice cubes out of the water storage container or ice cube mold and fall into the ice cube storage box 41.
[0118] In one embodiment, the ice-making mechanism includes an ice-making box 44, a compressor 45, a condenser 47, a capillary tube 48, and an evaporator 49, which are connected sequentially. The refrigerant, driven by the compressor 45, circulates between the condenser 47, the capillary tube 48, and the evaporator 49. The heat exchange tubes on the evaporator 49 are bent to form an evaporation head. This evaporation head is inserted into the ice-making box 44, which stores water for ice making. The water in the ice-making box 44 comes into contact with the evaporation head, forming ice. The ice then detaches from the evaporation head and is stored in an ice storage box 41. In this embodiment, the ice-making system using the compressor 45 is fast, produces a large quantity of ice, has high efficiency, and consumes little energy.
[0119] In one embodiment, a defrosting valve 46 is connected to the refrigerant outlet of the compressor 45. The outlet of the defrosting valve 46 is directly connected to the inlet of the evaporator 49, forming a refrigerant passage for defrosting the evaporator head. When ice needs to be removed from the evaporator head, the refrigerant in the compressor 45 enters the evaporator 49 directly through the defrosting valve 46, causing the evaporator head to heat up rapidly. At this time, the ice surface in contact with the evaporator head senses this temperature increase the fastest, causing the ice on the evaporator head to detach. The ice detached from the evaporator head first enters the ice-making box 44, where it forms an ice-water mixture with the cold water inside. Then, the ice is separated from the ice-making box 44 and stored in the ice storage box 41.
[0120] In one embodiment, the ice dispensing assembly includes an ice outlet 43 and a spiral shaft 42 for conveying ice blocks. The spiral shaft 42 is inclined, and the ice outlet 43 is connected to the high end of the spiral shaft 42. The bottom end of the spiral shaft 42 is connected to the ice block storage box 41. The spiral shaft 42 transports the ice blocks from the bottom end to the high end and discharges them through the ice outlet 43, thereby achieving automatic ice dispensing.
[0121] In one embodiment, the spiral shaft 42 is disposed inside the ice storage box 41, and the ice storage box 41 can be adapted to the tilted state of the spiral shaft 42.
[0122] In one embodiment, on the body of the multi-position coffee extractor, the ice outlet 43 is arranged side-by-side with the outlets of the first extraction component 1 and the second extraction component 16, or in a front-to-back or close-to-back position, for ease of use and in accordance with ergonomics. In another embodiment, a certain distance needs to be provided between the ice outlet 43 and the outlets of the first extraction component 1 and the second extraction component 16 to allow for simultaneous coffee extraction and ice dispensing.
[0123] In one embodiment, the ice dispensing component includes an ice dispensing port, which is located on the body of the multi-position coffee extractor and faces the ice storage box 41. This allows the user to manually remove ice from the ice storage box 41 through the ice dispensing port. This method avoids the use of a spiral shaft 42, simplifies the structure, and reduces costs.
[0124] In one embodiment, the ice dispensing port is located on the ice storage box 41, which is detachably connected to the body of the multi-position coffee maker. To dispense ice, the ice storage box 41 is removed from the machine body, and ice is dispensed directly from within the box, or the ice can be poured out. In another embodiment, the refrigeration assembly further includes a cold water assembly, which includes a cold water tank 30 for storing low-temperature cold water.
[0125] The cold water tank 30 is connected to the first extraction component 1 and is configured to provide low-temperature cold water to the first extraction component 1. The cold water tank 30 is also connected to the drinking water component 24 and is configured to provide low-temperature cold water to the drinking water component 24. The cold water tank 30 is also connected to the second extraction component 16 and is configured to provide low-temperature cold water to the second extraction component 16.
[0126] A third pump body 31 is connected to the cold water tank 30. A fourth three-way control valve 19 is connected to the outlet of the third pump body 31. One outlet of the fourth three-way control valve 19 is connected to the drinking water assembly 24, and the other outlet of the fourth three-way control valve 19 is connected to the second extraction assembly 16.
[0127] In this embodiment, the cold water tank 30 provides low-temperature cold water to the first extraction component 1, and the low-temperature cold water is discharged from the first extraction component 1, thereby realizing low-temperature extraction of coffee raw materials to obtain low-temperature coffee extract. As previously described, cold extraction is performed using room temperature water; here, low-temperature cold water is used for even lower-temperature cold extraction, which can yield coffee liquid with a more complex flavor profile.
[0128] In other embodiments, the cold water tank 30 is connected to the water dispensing assembly 24, and the cold water tank 30 is configured to provide low-temperature cold water to the water dispensing assembly 24. The cold water tank 30 provides low-temperature cold water to the water dispensing assembly 24 through the third pump body 31, enabling the multi-position coffee maker to receive low-temperature cold water. This allows the multi-position coffee maker to not only function as a water dispenser, but also to obtain hot water, room temperature water, and low-temperature cold water, improving its adaptability, increasing its functionality, and facilitating its widespread adoption.
[0129] In other embodiments, a cold water tank 30 is connected to a second extraction assembly 16, and the cold water tank 30 is configured to supply low-temperature cold water to the second extraction assembly 16. The cold water tank 30 supplies low-temperature cold water to the second extraction assembly 16 through a third pump body 31 and a fourth three-way control valve 19, enabling the second extraction assembly 16 to achieve a low-temperature cold extraction mode.
[0130] In the above embodiment, the cold water tank 30 is connected to the first extraction component 1, the second extraction component 16, and the water dispensing component 24, enabling the multi-position coffee maker to receive low-temperature cold water and simultaneously perform cold extraction of coffee at two positions. This makes the multi-position coffee maker not only a water dispenser but also capable of providing hot water, room temperature water, and low-temperature cold water, thus improving its adaptability, increasing its functionality, and facilitating its promotion.
[0131] In one embodiment, the outlet of the third pump body 31 connected to the drinking water assembly 24 is connected to the second water outlet 242.
[0132] In this embodiment, low-temperature cold water is prepared by the cold water component, allowing users to obtain low-temperature cold water directly at the water drinking component 24 without having to add ice cubes to room temperature water. This reduces the use of ice cubes, thereby reducing the amount of ice cubes prepared, which can reduce the volume of the ice cube storage box 41, shrink the size of the multi-position extraction coffee machine, and also reduce the ice production capacity of the ice making component 40, thus reducing energy consumption.
[0133] In this embodiment, cold water is prepared using a cold water assembly and stored in a cold water tank 30, allowing for temperature control of the cold water, such as obtaining cold water at 3-5°C. In contrast, adding ice to room temperature water to obtain cold water does not allow for temperature control.
[0134] In one embodiment, the cold water assembly, used for preparing low-temperature cold water, includes a cold water tank 30 and a cold water preparation device. In one embodiment, the cold water preparation device can be a semiconductor thermoelectric cooler. One side (cold end) of the thermoelectric module of the conductor thermoelectric cooler is tightly attached to the bottom or side of the cold water tank 30. The cold end cools the water flow inside the cold water tank 30 to obtain low-temperature cold water. The method of obtaining low-temperature cold water by cooling the water flow inside the cold water tank 30 using a semiconductor thermoelectric cooler has a simple structure.
[0135] In one embodiment, the cold water preparation device can be a compressor refrigeration system. The compressor refrigeration system includes an ice maker, a compressor, a condenser, a capillary tube, and an evaporator, which are connected sequentially. The refrigerant, driven by the compressor, circulates between the condenser, capillary tube, and evaporator. The heat exchange tubes on the evaporator are bent to form an evaporation head, which is inserted into the cold water tank 30 to cool the water flow within, thus obtaining low-temperature cold water. This compressor refrigeration system provides high efficiency and rapid cold water preparation.
[0136] In one embodiment, the cold water assembly is combined with the aforementioned ice-making assembly 40, specifically, the cold water tank 30 is combined with the aforementioned ice-making assembly 40, and more specifically, the cold water tank 30 is combined with the aforementioned compressor ice-making structure. During the ice-making process, the cold water in the ice-making container 44 is transported to the cold water tank 30 for storage, or low-temperature cold water. This method reduces the use of a separate refrigeration structure or system, simplifies the internal structure of the multi-position extraction coffee machine, and reduces purchase, usage, and maintenance costs.
[0137] In one embodiment, a separation box is installed at the bottom of the ice-making box 44. When the ice cubes on the evaporator head detach from the evaporator head and fall into the ice-making box 44, the ice-making box 44 is flipped so that the ice-water mixture in the ice-making box 44 enters the separation box. The bottom of the separation box is provided with a separation hole. Low-temperature cold water is discharged through the separation hole and introduced into the cold water tank 30 through a pipe. The ice cubes temporarily left in the separation box are sent into the ice cube storage box 41.
[0138] Specifically, a scraper is installed on the rotating shaft that drives the ice-making box 44 to rotate, and the scraper is located above or diagonally above the ice-making box 44. After the ice-making box 44 flips over, the ice-water mixture enters the separation box. As the ice-making box 44 flips back to its original position, the scraper scrapes the ice cubes in the separation box into the ice cube storage box 41.
[0139] In one embodiment, if ice making is not required and only low-temperature cold water needs to be prepared, the evaporator head on the evaporator 49 only cools the water flow in the preparation box, and it is not necessary to cool it to below zero degrees Celsius. A large amount of low-temperature cold water is quickly obtained, and then the low-temperature cold water is transported and stored in the cold water tank 30 by flipping the preparation box.
[0140] In one embodiment, the cold water tank 30 is an insulated tank, which has the function of keeping the low-temperature cold water in the cold water tank 30 at a low temperature for a relatively long period of time.
[0141] In one embodiment, the inlet of the cold water tank 30 is connected to the ice-making assembly 40. That is, the low-temperature cold water obtained during ice making is delivered to the cold water tank 30. As mentioned earlier, a separation box is installed at the bottom of the ice-making box 44. When ice blocks detach from the evaporator head and fall into the ice-making box 44, the ice-water mixture inside the ice-making box 44 is flipped, causing it to enter the separation box. The bottom of the separation box has a separation hole through which the low-temperature cold water is discharged and introduced into the cold water tank 30 through a pipe. In this embodiment, low-temperature cold water is obtained during the ice-making process, improving refrigeration efficiency and resulting in a large volume of low-temperature cold water.
[0142] In one embodiment, the outlet of the cold water tank 30 is connected to the ice-making assembly 40. In some locations, such as when the ambient temperature is high or ice-making has not been carried out for a long time and no low-temperature cold water is replenished to the cold water tank 30, the temperature of the low-temperature cold water originally stored in the cold water tank 30 will rise. At this time, by connecting the outlet of the cold water tank 30 to the ice-making assembly 40, the cold water in the cold water tank 30 that has been heated or is about to be heated is transported to the ice-making assembly 40, whereby the ice-making assembly 40 obtains low-temperature cold water again, and then the low-temperature cold water is stored back in the cold water tank 30. In this embodiment, the heated cold water in the cold water tank 30 enters the ice-making component 40. If it is not necessary to make new ice cubes at this time, the ice-making component 40 only cools the water flow in the ice-making box 44 to the required temperature, such as 0-5°C. At this time, it is not necessary to cool the water flow in the ice-making box 44 to below zero degrees, that is, it is not necessary to make ice cubes. This avoids the problem of too many ice cubes not being able to be contained in the ice cube storage box 41, and also avoids the waste of refrigeration energy.
[0143] In one embodiment, the cold water tank 30 is connected to the water source component 20 and is also connected to the ice-making component 40. The cold water tank 30 is used to receive the low-temperature cold water obtained by the ice-making component 40 and to supply ice-making water to the ice-making component 40.
[0144] In this embodiment, the cold water tank 30 is used to receive the low-temperature cold water obtained by the ice-making component 40. That is, the water inlet of the cold water tank 30 is connected to the ice-making component 40. Specifically, the water inlet of the cold water tank 30 is connected to the ice storage box 41. The ice stored in the ice storage box 41 will melt as the temperature rises or the storage time is too long. At this time, the water can be transported to the cold water tank 30 for use.
[0145] In this embodiment, the cold water tank 30 is connected to the water source component 20, that is, the outlet of the water tank is connected to the inlet of the cold water tank 30, and the room temperature water in the water tank enters the cold water tank 30.
[0146] In this embodiment, the cold water tank 30 supplies ice-making water to the ice-making assembly 40. The room temperature water in the water tank enters the cold water tank 30, or the original low temperature cold water in the cold water tank 30 is transported to the ice-making assembly 40 through the outlet of the cold water tank 30 to prepare ice blocks and / or prepare low temperature cold water.
[0147] In one embodiment, the outlet of the water tank is connected to the inlet of the cold water tank 30, enabling the transfer of room temperature water from the water tank to the cold water tank 30. The room temperature water then flows through the outlet of the cold water tank 30 to the refrigeration unit for cooling, producing low-temperature cold water. This low-temperature cold water then re-enters the cold water tank 30. When a large amount of room temperature water is added to the cold water tank 30 at once, the water needs to be transferred multiple times through a water pipe to the refrigeration unit for multiple cooling cycles until the desired temperature of the cold water is obtained.
[0148] In one embodiment, a fifth pipe 32 is connected to the cold water tank 30, and a first two-inlet-one-outlet control valve is connected to the end of the fifth pipe 32. The fifth pipe 32 is connected to one inlet of the first two-inlet-one-outlet control valve, and the other inlet of the first two-inlet-one-outlet control valve is connected to the water source component 20. The outlet of the first two-inlet-one-outlet control valve supplies low-temperature cold water to the first extraction component 1.
[0149] In this embodiment, the fifth pipeline 32 forms a low-temperature cold water passage from the cold water tank 30 to the first extraction component 1, enabling the low-temperature cold water in the cold water tank 30 to be delivered to the extraction outlet, thereby achieving low-temperature extraction of the coffee raw materials and obtaining low-temperature coffee extract. Specifically, the low-temperature cold water in the cold water tank 30 passes through the first two-inlet-one-outlet control valve, the first pump body 3, and the first three-way control valve 4, directly entering the first extraction component 1 to extract the coffee raw materials in the extraction handle connected to the first extraction component 1.
[0150] In this embodiment, the water tank and the cold water tank 30 are connected in parallel to the first pump body 3 through the first two-inlet-one-outlet control valve, so that the first pump body 3 can supply low-temperature cold water or room temperature water to the first extraction component 1 or room temperature water to the first heating component 5 as needed, thereby reducing the use of the pump body, reducing manufacturing costs, and reducing the size of the equipment.
[0151] In one embodiment, the drinking water assembly 24 includes a first outlet 241 and a second outlet 242. The first outlet 241 is connected to the second heating assembly 23 and is configured to output heated drinking water, while the second outlet 242 is configured to output unheated drinking water. The first outlet 241 is the hot water outlet, and the second outlet 242 is the cold water outlet. The second outlet 242 is also connected to a fourth pipe 26, allowing it to output room temperature water as well. The first outlet 241 and the second outlet 242 are independently configured, enabling simultaneous access to both hot and cold water.
[0152] In one embodiment, the hot water outlet and the cold water outlet are arranged side by side, and there is a sufficient distance between the hot water outlet and the cold water outlet to facilitate the simultaneous connection of hot water and cold water.
[0153] In one embodiment, the first extraction component 1 includes a first brewing head, which includes a first extraction outlet. The drinking water outlet and the second extraction outlet are arranged side by side, improving the user experience and conforming to ergonomics.
[0154] In one embodiment, the second extraction component includes a second brewing head, which in turn includes a second extraction outlet. The drinking water outlet and the second extraction outlet are arranged side-by-side, improving the user experience and conforming to ergonomics.
[0155] In one embodiment, a sixth pipe 10 is connected to the second heating component 23, and the sixth pipe 10 is configured to provide hot water to the cooling component. The hot water prepared by the second heating component 23 is transported to the cooling component through the sixth pipe 10, so as to achieve regular high-temperature cleaning and sterilization of the cooling component and ensure the cleanliness of the cooling component.
[0156] In one embodiment, the multi-position coffee maker further includes a grinding assembly 60. The grinding assembly 60 includes a bean hopper 61, a grinding component, and a dispensing component. The dispensing component includes a dispensing port 64, which is connected to the grinding component. The grinding component is connected to the bean hopper 61. The grinding component includes a fixed blade 65 and a movable blade 651, and the gap 66 between the fixed blade 65 and the movable blade 651 is adjustable.
[0157] In this embodiment, the grinding component 60 in the multi-position coffee maker grinds coffee beans into coffee powder. The freshly ground coffee powder is then placed in the extraction container, such as the extraction portafilter, and the portafilter is placed at the first extraction component 1 and / or the second extraction component 16 for extraction to obtain concentrated coffee. In this embodiment, the grinding component 60 in the multi-position coffee maker enables the machine to not only extract coffee but also grind coffee powder, obtaining freshly ground coffee powder for immediate extraction. This shortens the storage time after grinding, improves the taste of the brewed coffee, and meets people's growing appreciation and demands for coffee.
[0158] In this embodiment, the gap 66 between the fixed cutter head 65 and the moving cutter head 651 is adjustable, which means that the fineness of the coffee powder obtained by grinding can be adjusted to adapt to different coffee powder grinding requirements and different users' requirements for coffee taste, thus having good adaptability.
[0159] In one embodiment, the grinding assembly includes a fixed blade head 65 and a movable blade head 651, as well as a fixed blade holder 67 and a movable blade holder. The fixed blade head 65 is fixedly installed on the fixed blade holder 67, and the movable blade head 651 is rotatably installed on the movable blade holder. After installation, the fixed blade head 65 is sleeved outside the movable blade head 651. The gap 66 between the fixed blade head 65 and the movable blade head 651 is the grinding area. Coffee enters the grinding area, and the movable blade head 651 rotates relative to the fixed blade head 65 to grind the coffee in the grinding area. The obtained coffee powder is discharged by the powder dispensing assembly.
[0160] In one embodiment, the fixed cutter head 65 and the movable cutter head 651 are coaxially arranged. A drive assembly 62 is connected to the movable cutter head 651. The drive assembly 62, such as a drive motor, is used to drive the movable cutter head 651 to rotate around its own axis, so as to achieve relative rotation with the fixed cutter head 65 and to grind the coffee beans located in the gap 66 between the fixed cutter head 65 and the movable cutter head 651.
[0161] In one embodiment, the drive assembly 62 is fixedly installed with the moving blade holder, and the moving blade holder is fixedly installed with the coffee machine body.
[0162] In one embodiment, a gap 66 adjustment device is connected to the fixed blade holder 67 to adjust the size of the gap 66 between the fixed blade head 65 and the moving blade head 651. Generally, the position of the fixed blade head 65 is adjusted along the axial direction of the moving blade head 651. The fixed blade holder 67 and the fixed blade head 65 are moved by the gap 66 adjustment device, so that the fixed blade head 65 is away from the moving blade head 651. This increases the gap 66 between the fixed blade head 65 and the moving blade head 651, allowing for coarser coffee powder to be ground. Conversely, if the fixed blade head 65 is moved closer to the moving blade head 651, the gap 66 between the fixed blade head 65 and the moving blade head 651 is decreased, allowing for finer coffee powder to be ground.
[0163] In one embodiment, as shown in the figure, a transmission threaded sleeve 69 is connected to a fixed tool holder 67. The inner wall of the transmission threaded sleeve 69 is fixedly connected to the fixed tool holder 67. A transmission driven gear is provided on the outer wall of the transmission threaded sleeve 69. The axial direction of the transmission driven gear coincides with the axial direction of the fixed tool head 65. An adjusting ring 68 is meshed with the transmission driven gear. By rotating the adjusting ring 68, the transmission threaded sleeve 69 can be driven to move axially, that is, the fixed tool head 65 can be driven to move along its own axial direction.
[0164] In one embodiment, the coffee dispensing assembly includes a powder guiding channel 63 and a powder dispensing port 64. One end of the powder guiding channel 63 is connected to the grinding area, and the other end is connected to the powder dispensing port 64. During coffee bean grinding, an extraction portafilter is installed at the powder dispensing port 64. The coffee powder obtained after grinding by the grinding assembly enters the portafilter bowl on the extraction portafilter through the powder guiding channel 63 and the powder dispensing port 64. After grinding is completed, the extraction portafilter containing the coffee powder is installed on the first extraction assembly 1 or the second extraction assembly 16 to perform coffee extraction.
[0165] In one embodiment, the powder outlet 64 is located on one side of the first or second brewing head for easy powder collection. Of course, depending on layout requirements, the powder outlet 64 can also be located in other positions, such as... Figure 2 As shown, the powder outlet 64 is located behind the first brewing head, which helps to reduce the size of this multi-position extraction coffee machine in the left-right width direction, thus achieving miniaturization of the multi-position extraction coffee machine.
