Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, and in particular to a fully automatic coffee machine. Background Art

[0002] The word "coffee" comes from Arabic It means "plant beverage". People all over the world love to drink coffee more and more. The "coffee culture" that follows fills every moment of life. Whether at home, in the office, or in various social occasions, people are tasting coffee. It is gradually associated with fashion, modern life, work and leisure and entertainment. The Chinese people's habit of drinking coffee began after the 1990s. Now many urban people have become dependent on coffee. Although the annual consumption of coffee in my country is only 200,000 tons, the per capita consumption is increasing at a rate of 30%, and it is expected to become the world's most potential coffee consumption country.

[0003] In order to cater to the tastes of consumers, many types of coffee drinks have appeared on the market, such as instant coffee that can be brewed directly, freshly ground coffee with better taste, and espresso with strong taste. Among them, espresso is extracted by using hot water at about 92°C and high pressure (9 bar) to rush through finely ground coffee powder. Compared with instant coffee and freshly ground coffee, its aroma is richer and stronger, and is more popular with consumers. Its production requires grinding and powdering coffee beans, spreading and compacting the coffee powder, and assembling it on a semi-automatic coffee machine for coffee extraction.

[0004] At present, there are coffee machines on the market that can fully automatically extract coffee. They are small in size and can only grind coffee powder of a single particle size. In addition, the device used to boil water is only an instant heating device. During the process of extracting coffee, the temperature cannot be accurately controlled, and the pressure is low and unstable. The water temperature and pressure for extraction are the main factors affecting the taste of coffee. Therefore, the coffee made by the current fully automatic coffee machines is relatively simple and has a poor taste.

[0005] In order to pursue the taste of coffee, some mid- to high-end coffee shops on the market currently use semi-automatic coffee machines for coffee extraction. That is, the water in the electric boiler is heated to generate high pressure to extract coffee powder, thereby making espresso. However, the grinding, spreading, and pressing of coffee powder require manual operation, and require too much reliance on the personal experience of the barista, which makes the process of making espresso take a long time.

[0006] The entire process is relatively complicated and requires manual operation by a barista, which also requires a high level of experience. However, as the pace of life and work becomes faster and faster, the self-service business model is increasingly accepted by the market and the public. Existing coffee machines are not suitable for the self-service business model. Therefore, there is an urgent need for a device that can automatically make espresso. Summary of the invention

[0007] The purpose of the present invention is to provide a fully automatic coffee machine that can automatically grind coffee powder and automatically extract espresso, which can reduce the barista's operation in the entire coffee grinding and extraction process and complete it completely automatically.

[0052] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0053] It should be noted that in the embodiments of the present invention, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0054] In addition, the descriptions of “first”, “second”, etc. in the embodiments of the present invention are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.

[0055] The embodiment of the present invention provides a fully automatic coffee machine, such as Figure 1-9As shown, a coffee bean grinder 100 for grinding coffee beans and a semi-automatic coffee machine 200 for brewing and extracting coffee powder are arranged side by side on the table top of the machine 01. At the same time, a powder distribution and pressing device 400 for distributing and pressing the coffee powder, and a conveying device 500 for clamping the powder cup 300 and then transferring it among the coffee bean grinder 100, the powder distribution and pressing device 400 and the semi-automatic coffee machine 200 are also arranged. During the process of coffee extraction, the conveying device 500 clamps the powder cup 300 and conveys it to the corresponding position of the coffee bean grinder 100 to hold the coffee powder ground by the coffee bean grinder 100; then, the powder cup 300 containing the coffee powder is conveyed to the corresponding position of the powder distributing and pressing device 400, wherein the powder distributing component 410 of the powder distributing and pressing device 400 performs powder distributing processing on the coffee powder contained in the powder cup 300, so that the coffee powder is evenly distributed in the powder cup 300, and the pressing component 420 of the powder distributing and pressing device 400 evenly distributes the coffee powder in the powder cup 300. 00 is compacted; the conveying device 500 transfers the powder cup 300 toward the semi-automatic coffee machine 200, so that the powder cup 300 and the semi-automatic coffee machine 200 are connected with each other, and the semi-automatic coffee machine 200 allows high-temperature and high-pressure water to flow through the powder cup 300, thereby extracting and making coffee; after the coffee extraction is completed, the conveying device transports the powder cup containing the coffee powder residue back to the coffee bean grinder, and removes the coffee powder residue in the powder cup through the residue removal device and cleans the powder cup, so as to prepare for the next time of filling coffee powder.

[0056] During the process of coffee extraction, one only needs to wait at the semi-automatic coffee machine 200 with a cup to receive the extracted coffee. The whole process does not rely on manual operation of the barista, and can automatically complete the grinding, distribution, pressing and extraction of coffee powder, thereby greatly improving the efficiency of coffee making. By automatically making coffee, it can adapt to the current self-service business model and conform to the fast-paced life and work style.

[0057] In this embodiment, the powder cup 300 has a body 301. Figure 4 As shown, the upper side is a large-sized injection port for receiving coffee powder ground by the coffee bean grinder 100, and the outflow port is located at the lower side of the main body 301, so that water can flow out of the outflow port during the coffee extraction process. At the same time, in order to more conveniently place the powder cup 300, a positioning portion 302 is formed on the lower side of the main body. In this embodiment, the positioning portion 302 is a multi-faceted block welded to the lower side of the main body. In other embodiments, the positioning portion 302 can also be a plurality of block structures with a fool-proof design.

[0058] In the process of filling the coffee powder ground by the coffee bean grinder 100, the conveying device 500 conveys the coffee powder to the discharge port 101 of the coffee bean grinder 100 through the powder cup 300, so that the coffee powder is filled in the powder cup 300 when it flows out through the discharge port 101. At this time, in order to more conveniently receive the coffee powder, a vibrating powder receiving table 110 is further configured on the coffee bean grinder 100. Figure 5 As shown, the vibrating powder receiving table 110 includes a lifting cylinder 111, a mounting plate 112 and a vibrator 114, wherein the lifting cylinder 111 is fixedly mounted on the table of the machine table 01, and its piston rod extending in the vertical direction is fixedly connected to one end of the mounting plate 112, so that the mounting plate 112 is suspended below the discharge port 101 of the coffee bean grinder 100, and reciprocates in the up and down directions under the drive of the lifting cylinder 111. At the same time, the mounting plate 112 supports and is also provided with a placement position 113 for placing the powder cup 300. In this embodiment, the placement position 113 is configured as a groove structure that is compatible with the positioning portion 302 of the powder cup 300, so that the powder cup 300 can be stably placed on the mounting plate 112. The vibrator 114 is fixedly mounted on the lower surface of the mounting plate 112, thereby driving the mounting plate 112 to vibrate and drive the powder cup 300 to vibrate. In this embodiment, the vibrator 114 is a pneumatic vibrator 114. The high-pressure gas discharged by the external air compressor causes the vibrator 114 to generate a vibration force, thereby driving the mounting plate 112 and the powder cup 300 located thereon to vibrate.

[0059] In the present invention, the vibrating powder receiving table is also equipped with a weighing device, such as Figure 5 As shown, the weighing device is fixedly installed on the mounting plate, and at the same time, a placement plate is fixedly connected to the top thereof, and the placement position is opened on the top surface of the placement plate. When the powder cup is installed on the placement position and in the process of receiving coffee powder, the weighing device measures its weight, thereby strictly controlling the weight of the coffee powder. Since the weight of coffee powder required for extracting coffee is different for different types of coffee beans, the weighing device can accurately detect and control it, thereby ensuring that the required weight of coffee powder is within a predetermined range, thereby ensuring the quality of the extracted coffee. In this embodiment, the weighing device takes an electronic scale as an example.

[0060] During the process of installing the coffee powder in the powder cup 300, the moving device transports the powder cup 300 to the corresponding position of the mounting plate 112. The mounting plate 112 is raised under the drive of the lifting cylinder 111, so that the powder cup 300 is received on the placement position 113. Then, the lifting cylinder 111 moves the powder cup 300 to the position corresponding to the discharge port 101 of the coffee bean grinder 100 to receive the coffee powder ground by the coffee bean grinder 100. During the process of the coffee powder flowing into the powder cup 300, the vibrator 114 drives the mounting plate 112 and the powder cup 300 thereon to vibrate, so that after the coffee powder flows into the powder cup 300, under the vibration of the powder cup 300, the coffee powder is more evenly distributed in the powder cup 300 to avoid piling. It can be imagined that the particles of coffee powder are small and have certain oily substances. In the process of coffee powder piling up, the friction between the particles is large and it is easy to accumulate into a pile. Therefore, in the process of coffee powder flowing into the powder cup 300, the coffee powder flows out along the discharge port 101 of the coffee bean grinder 100, and gradually accumulates in the powder cup 300, below the discharge port 101. As the time of coffee powder flowing out increases, the height and volume of the accumulated coffee powder gradually increase. At this time, the transportation and subsequent operation of the powder cup 300 containing coffee powder are greatly affected. For example, during the transportation of the powder cup 300, due to vibration or operation during the transfer process, the accumulated coffee powder pile collapses, causing the coffee powder to fall out of the powder cup 300, reducing the quality of the coffee powder, thereby affecting the quality of the extracted coffee and seriously affecting the taste of the espresso; for another example, during the distribution of coffee powder, due to the large and high volume of the accumulated coffee powder pile, during the distribution process, under the operation of the powder distribution component 410, the coffee powder falls out of the powder cup 300, thereby reducing the treatment of the coffee powder and affecting the taste of the extracted espresso. The vibrator 114 drives the mounting plate 112 and the powder cup 300 located thereon to vibrate, so that after the coffee powder flows into the powder cup 300, the coffee powder piled up can be flattened by the vibration force, so that it is evenly distributed in the powder cup 300 without being gathered in piles. At the same time, one end of the mounting plate 112 is fixedly connected to the piston rod of the lifting cylinder 111, so that it is suspended in a cantilever structure below the discharge port 101 of the grinder, so that the mounting plate 112 can respond more quickly under the drive of the vibrator 114, and can quickly follow the vibrator 114 to vibrate, and the vibration amplitude is large, thereby being able to provide a greater vibration force to the powder cup 300 located thereon, so that the coffee powder contained in the powder cup 300 can be more evenly distributed in the powder cup.

[0061] like Figure 6As shown, the powder distribution and pressing device 400 includes a first linear module 401 arranged vertically, and a mounting seat 402 is connected thereto by driving, and a powder distribution component 410 and a pressing component 420 are installed on the mounting seat 402. Under the drive of the first linear module 401, the mounting seat 402 and the powder distribution component 410 and the pressing component 420 located thereon can be driven to reciprocate in the vertical direction. The powder distribution component 410 includes a powder distribution driving device 411 fixedly mounted on the mounting seat 402 and a powder distributor 412 connected thereto by transmission. In this embodiment, the powder distribution driving device 411 is a motor, and the powder distributor 412 is connected to the transmission shaft of the motor by transmission, so as to drive the powder distributor 412 to rotate along its axis, wherein the other end of the powder distributor 412 extends downward, thereby forming a powder distribution head 413 adapted to the injection port of the powder cup 300.

[0062] During the powder distribution process, the conveying device 500 conveys the powder cup 300 containing only coffee powder to the lower side of the powder distribution component 410. At this time, the mounting seat 402 is driven downward by the first linear module 401, and the powder distribution head 413 of the powder distributor 412 is connected to the powder cup 300, that is, the powder distribution head 413 is placed in the powder cup 300, and the powder distributor 412 is driven to rotate by the powder distribution driving device 411, so that the coffee powder is stirred and distributed in the powder cup 300, so that the coffee powder is distributed more evenly in the powder cup 300, that is, the upper surface of the coffee powder is a flat plane, so as to avoid uneven distribution of coffee powder, thereby affecting the extraction quality of coffee.

[0063] The pressing assembly 420 in the powder distribution and pressing device 400 is used to compact the coffee powder that has been distributed in the powder cup 300, thereby reducing the gaps between the coffee powder particles. The coffee powder has enough pressure to resist the water flow, so that the water flow can prevent the loose coffee powder from being directly dispersed by the water flow during the coffee extraction process, resulting in a channel effect and uneven coffee extraction. Figure 6 As shown, the compacting assembly 420 includes a powder pressing hammer 421 fixedly mounted on the mounting seat 402. In this embodiment, the upper end of the powder pressing hammer 421 is fixedly mounted on the lower surface of the mounting seat 402, and the lower end thereof extends downward. In the process of compacting the coffee powder, the conveying device 500 moves the powder cup 300, which has been distributed with powder, toward the compacting assembly 420, and places the powder cup 300 directly below the powder pressing hammer 421. Under the drive of the first linear module 401, the powder pressing hammer 421 moves downward and is placed inside the powder cup 300, compacting and compacting the coffee powder evenly distributed inside the powder cup 300.

[0064] It is conceivable that during the process of filling, spreading and compacting coffee powder, a small amount of coffee powder will be brought out and fall on the upper edge of the powder cup 300. Due to the existence of coffee powder, when the powder cup 300 is installed on the semi-automatic coffee machine 200, there will be a certain gap at the connection between the powder cup 300 and the semi-automatic coffee machine 200, resulting in a poor seal. During the process of extracting coffee, pressure leakage will occur. Figure 6 As shown, the powder distribution and pressing device 400 is further provided with a powder scraping assembly 430, which is used to remove the coffee powder on the upper edge of the powder cup 300, so as to ensure that after the powder cup 300 is installed on the semi-automatic coffee machine 200, its connection can be tightly sealed. The powder scraping assembly 430 includes a mounting member 431 in a cantilever structure and a powder scraping member 432 installed on the mounting frame and facing the downward direction. During design and installation, the lower surface of the powder scraping member 432 and the upper edge surface of the powder cup 300 are located on the same plane; in the process of the powder cup 300 being transported toward the semi-automatic coffee machine 200 through the conveying device 500, the upper edge surface of the powder cup 300 and the lower edge surface of the powder scraping member 432 contact each other and move relative to each other, so that the coffee powder on the upper edge of the powder cup 300 is scraped off.

[0065] In this embodiment, the mounting member 431 is a box-shaped structure, a sponge is installed inside, and the powder scraping member 432 is made of sponge. In other embodiments, the mounting member 431 is a plate-shaped or block-shaped structure, and the powder scraping member 432 is made of cloth or leather wrapped on the mounting member 431.

[0066] In this embodiment, if Figure 7-8As shown, the conveying device 500 is used to clamp the powder cup 300 and reciprocate between the coffee bean grinder 100, the powder distribution and pressing device 400 and the semi-automatic coffee machine 200, wherein the conveying device 500 includes a first conveying component 510 corresponding to the coffee bean grinder 100 and a second powder distribution component 410 corresponding to the powder distribution and pressing device 400 and the semi-automatic coffee machine 200, wherein the first conveying component 510 includes a second linear module 511 arranged along a first predetermined direction and located beside the coffee bean grinder 100, wherein the first predetermined direction is the first direction of the second linear module 511, and the second linear module 511 is arranged along a first predetermined direction and located beside the coffee bean grinder 100. The fixed direction is the Y-axis direction with the coffee bean grinder 100 and the semi-automatic coffee machine 200 being arranged side by side as the X-axis. One end of the mounting arm 512 is transmission-connected to the second linear module 511 and reciprocates along the Y-axis direction under the drive. The other end thereof extends outward. The clamping claw 513 is fixedly mounted on the end of the mounting arm 512 extending outward to clamp the powder cup 300. When the first conveying assembly 510 conveys the powder cup 300, the powder cup 300 is clamped by the clamping claw 513 and is moved on the second linear module 511. The second conveying assembly 520 includes a third linear module 521 drawn along a second predetermined direction and a fourth linear module 522 connected thereto and arranged in a vertical direction. The fourth linear module 522 reciprocates along the second predetermined direction under the drive of the third linear module 521, wherein the second predetermined direction is the parallel direction of the coffee bean grinder 100 and the semi-automatic coffee machine 200. Direction, that is, the X-axis direction, one end of the bottom plate 523 is installed on the fourth linear module 522, and is driven by the fourth linear module 522 to reciprocate in the vertical direction. At the same time, the other end of the bottom plate 523 extends toward the parallel direction of the coffee bean grinder 100 and the semi-automatic coffee machine 200, and is provided with a positioning groove 524 for accommodating the powder cup 300 and matching with the positioning portion 302. In this embodiment, the positioning groove 524 is also a slot with a multi-faceted structure, so that the positioning portion 302 can be positioned to prevent the powder cup 300 from moving on the bottom plate 523.

[0067] During the conveying process of the powder cup 300, the clamping claw 513 of the first conveying component 510 clamps the powder cup 300 and, under the drive of the second linear module 511, conveys it to the mounting plate 112 located below the discharge port 101 of the coffee bean grinder 100, so as to install coffee powder on the powder cup 300. After the installation is completed, the powder cup 300 containing coffee powder is removed from the mounting plate 112 and transferred to the bottom plate 523 of the second conveying component 520. Specifically, the powder cup 300 containing coffee powder is placed in the positioning groove 524 of the bottom plate 523, and driven by the third linear module 521 and the fourth linear module 522, the powder cup 300 containing coffee powder is conveyed to the relative positions of the powder distributing and pressing device 400 and the semi-automatic coffee machine 200 for powder distributing, compacting and extraction processing.

[0068] In this embodiment, the powder cup 300 is connected to the semi-automatic coffee machine 200 by snapping. Specifically, two clamping blocks are provided on the body 301 of the powder cup 300, and a corresponding clamping slot is provided on the semi-automatic coffee machine 200. After the clamping blocks are placed in the clamping slots, the powder cup 300 is rotated to clamp it on the semi-automatic coffee machine 200 to extract coffee. A structure for driving the powder cup 300 to rotate is also provided on the second conveying assembly 520, such as Figure 8 The rotating block 525 is rotatably connected to the bottom plate 523. At the same time, the positioning groove 524 is provided on the top of the rotating block 525. The rotating drive device 526 is fixedly installed on the bottom plate 523 and is transmission-connected to the rotating block 525, thereby driving the rotating block 525 to rotate along its axis. In this embodiment, the rotating drive device 526 is a motor, and the motor is connected to the lower end of the rotating block 525 through a transmission belt, thereby driving the rotating block 525 to rotate. At this time, the positioning groove 524 is provided on the top surface of the rotating block 525. Therefore, after the powder cup 300 is installed in the positioning groove 524, the rotating block 525 can drive the powder cup 300 to rotate, thereby facilitating its installation on the semi-automatic coffee machine 200.

[0069] In the present embodiment, the residue removal device 600 is installed directly below the corresponding clamping jaw 513, and includes a residue removal component 610 and a cleaning component 620 arranged along a first predetermined direction, wherein the residue removal component 610 is used to remove the coffee residues in the powder cup 300. In the present embodiment, the residue removal component 610 is a water spray pipe interconnected with an external high-pressure water source, and the coffee powder in the powder cup is flushed by high-pressure and high-speed water flow, thereby flushing it quickly; the cleaning component 620 is used to remove the residual moisture in the powder cup 300, so that the coffee powder can be better contained, and the coffee powder will not be contaminated by external moisture and reduce the taste of the coffee. In the present embodiment, the cleaning component 620 is a blow pipe interconnected with a hot air source, and high-temperature hot air is blown to the flushed powder cup to dry the moisture on the powder cup. In this embodiment, in order to facilitate the cleaning of the powder cup 300, a rotating cylinder 514 is further installed on the mounting arm 512, and the clamping jaw 513 is installed on the rotating cylinder 514 and flipped under the drive thereof. After the clamping jaw 513 holding the powder cup 300 is flipped, the injection port of the powder cup 300 faces downward, thereby facilitating the residue removal device 600 located directly below the clamping jaw 513 to remove the coffee residue in the powder cup 300.

[0070] During the process of cleaning the coffee powder residue on the powder cup, the rotating cylinder drives the powder cup to rotate and flip it so that the opening of the powder cup faces directly downward, and moves along the first predetermined direction on the driving straight line of the second module, that is, the powder cup is moved to directly above the residue removal component and the cleaning component in sequence, so that the coffee powder residue in the powder cup is flushed by high-pressure water flow, and then the cleaned powder cup is dried by high-temperature air flow, thereby completing the cleaning of the powder cup.

[0071] The working process of a fully automatic coffee machine provided by an embodiment of the present invention is as follows:

[0072] The first conveying assembly 510 clamps the powder cup 300, and moves the powder cup 300 to the top of the mounting plate 112 under the drive of the second linear module 511. The mounting plate 112 receives the powder cup 300 under the drive of the lifting cylinder 111, and places it on the placement position 113 to facilitate the installation of coffee powder. The coffee bean grinder 100 grinds the coffee beans and discharges the coffee powder at the discharge port 101, so that it is installed in the powder cup 300. At the same time, the vibrator 114 drives the mounting plate 112 and the powder cup 300 thereon to vibrate, so that the installation The coffee powder therein is flattened by vibration to eliminate the accumulated powder pile; at the same time, due to the different types of coffee used in preparing coffee, the weight of the required coffee powder is different. In the process of the powder cup receiving the coffee powder, the weighing device detects the weight of the powder cup and the coffee powder therein, so that the weight of the coffee powder in the powder cup is within a predetermined range, thereby ensuring the taste of the extracted coffee; then, the second linear module 511 drives the clamping claw 513 to move toward the coffee bean grinder 100 again, so as to grab the powder cup 300 containing the coffee powder and transport it to the second transport unit. The powder cup 300 is mounted on the bottom plate 523 of the powder delivery assembly 520. Specifically, the second linear module 511 drives the clamping claw 513 and the powder cup 300 to move to the top of the positioning groove 524 of the bottom plate 523. The bottom plate 523 rises under the drive of the fourth linear module 522, so that the positioning portion 302 of the powder cup 300 is accommodated in the positioning groove 524, so that the powder cup 300 can be stably installed on the bottom plate 523. The bottom plate 523 and the powder cup 300 are driven by the third linear module 521 and the fourth linear module 522 to pass through the powder distribution assembly 410, The pressing assembly 420 and the powder scraping assembly 430 respectively spread and press the coffee powder in the powder cup 300 and clean the powder cup 300 to prepare for coffee extraction; the third linear module 521 and the fourth linear module 522 drive the bottom plate 523 and the powder cup 300 thereon to move toward the semi-automatic coffee machine 200, and dock the powder cup 300 with the semi-automatic coffee machine 200, and the rotary drive device 526 drives the rotating block 525 to rotate, so that the powder cup 300 is installed on the semi-automatic coffee machine 200 to extract coffee. In the whole process, the participation of the barista is not required, which greatly reduces the workload of the barista. At the same time, the extraction of coffee is faster, and the consumer only needs to receive the extracted coffee at the semi-automatic coffee machine 200.After the coffee extraction is completed, the powder cup 300 is transferred to the clamping claw 513 of the first conveying assembly 510, and the powder cup 300 that has been extracted is turned over by the driving of the rotating cylinder 514, so that the injection port of the powder cup 300 faces downward. At this time, the residue removal assembly 610 and the cleaning assembly 620 of the residue removal device 600 operate the powder cup 300 in turn to remove the coffee residue in the powder cup 300 and clean the powder cup 300. The cleaned powder cup 300 repeats the above actions again under the driving of the conveying device 500, so as to extract coffee again. At the same time, a shell 02 is provided on the machine platform 01 for covering and protecting the coffee bean grinder 100, the powder distribution and pressing device 400, the conveying device 500 and the semi-automatic coffee machine 200, so as to provide protection during the coffee extraction process to avoid accidental contact with the working mechanism and cause safety hazards. It can be imagined that a window is provided at the semi-automatic coffee machine to facilitate the collection of coffee.

[0073] It is understandable that the fully automatic coffee machine provided by the present invention also has a control system for controlling the coffee machine according to a predetermined production process so that it can automatically prepare coffee, and can extract coffee using different temperatures, pressures and water volumes according to different coffee recipes, thereby achieving a stable coffee taste and being able to replicate the coffee made by top baristas to the greatest extent possible, wherein the above-mentioned coffee recipe refers to the different weights of coffee powder used when extracting coffee due to different types of coffee beans; at the same time, the control system has a storage module for storing various parameters required for making different coffees, such as coffee bean types, coffee powder weight, extraction temperature, pressure and water volume, thereby ensuring a uniform standard for the taste of the coffee.

[0074] The embodiment of the present invention provides a fully automatic coffee machine, which can automatically complete the processes of grinding, distributing, compacting, extracting and removing grounds of coffee powder, without relying on a barista to operate the entire process, thereby improving the self-service and automatic performance of the coffee machine, and can make espresso more conveniently and quickly.
