Description

Technical Field

[0001] This disclosure relates to the field of coffee machine technology, and in particular to a fully automatic coffee machine. Background Technology

[0002] Most coffee machines on the market consist of separate coffee bean grinders and coffee brewers, meaning they operate independently. Users need to prepare both to enjoy freshly ground coffee. To achieve full automation, some coffee machines are integrated, combining multiple coffee-making modules, including grinding, tamping, and extraction. These modules are then electrically controlled, turning on or off sequentially according to the coffee-making process.

[0003] However, traditional coffee machines are limited by the shape of their different modules, leading to assembly interference. This necessitates increasing the overall size of the machine, preventing miniaturization. Furthermore, cleaning coffee grounds after extraction is difficult in traditional machines. They must be manually removed or rinsed internally. During internal rinsing, the concave structure of the portafilter bowl causes coffee grounds to easily splatter, contaminating the machine's interior. Without proper maintenance, this leads to bacterial growth inside the machine, directly reducing the safety of the brewed coffee. Utility Model Content

At each station, the components work in sequence with the coffee bowl to grind, tamp, extract, and remove coffee grounds. Integrating all components onto a station indexing plate effectively prevents interference and reduces overall size. Furthermore, when rotating to the grounds removal station, the tilting mechanism flips the coffee bowl so that its rim faces downwards, facilitating the removal of coffee grounds and preventing splattering during cleaning, thus significantly improving coffee safety.

[0024] Please see Figure 1 This is a schematic diagram of the structure of a fully automatic coffee machine according to an embodiment of the present disclosure.

[0025] Please refer to the following: Figure 2An embodiment of a fully automatic coffee machine 10 includes a housing 100, a dividing assembly 200, a portafilter assembly 300, a grinding assembly 400, a tamping assembly 500, an extraction assembly 600, and a waste disposal assembly 700. The dividing assembly 200 is disposed within the housing 100 and includes a workstation dividing plate 210 and dividing support columns 220. The dividing support columns 220 are connected to the bottom of the housing 100 and the workstation dividing plate 210, respectively, forming a portafilter transfer channel between the bottom of the housing 100 and the workstation dividing plate 210. The portafilter assembly 300 is located within the portafilter transfer channel. (Please refer to the attached document for further details.) Figure 3 The coffee bowl assembly 300 includes a coffee bowl 310, a rotating bowl 320, and a tilting bowl 330. The coffee bowl 310 is connected to the tilting end of the tilting bowl 330, and the rotating end of the rotating bowl 320 is connected to the tilting bowl 330. The rotating bowl 320 is connected to the indexing support column 220 to allow the coffee bowl 310 to move between the various stations of the workstation indexing plate 210. The coffee grinding assembly 400 is connected to the workstation indexing plate 210 and corresponds to a specific grinding station on the workstation indexing plate 210. The coffee grinding assembly 400 is used to grind coffee beans into powder. The tamping assembly 500 is connected to the workstation indexing plate 210 and corresponds to a specific tamping station on the workstation indexing plate 210. The tamping assembly 500 is used to tamp the coffee powder inside the coffee bowl 310. The extraction component 600 is connected to the workstation indexing plate 210, and the extraction component 600 corresponds to the extraction station of the workstation indexing plate 210. The extraction component 600 is used to extract coffee grounds in the coffee bowl 310. The waste removal component 700 is connected to the workstation indexing plate 210, and the waste removal component 700 corresponds to the waste removal station of the workstation indexing plate 210. The waste removal component 700 is used by the flipper 330 to flip the coffee bowl 310 and remove coffee grounds.

[0026] In this embodiment, the coffee bowl 310, driven by the rotating bowl component 320, sequentially passes through the grinding station, tamping station, extraction station, and grounds removal station. At each station, each component cooperates with the coffee bowl 310 to grind, tamp, extract, and remove coffee grounds. Integrating all working components onto the station indexing plate 210 effectively avoids mutual interference and reduces the overall size. Furthermore, when rotating to the grounds removal station, the tilting bowl component 330 flips the coffee bowl 310 so that its rim faces downwards, facilitating the removal of coffee grounds and preventing coffee grounds from splashing during cleaning, thus effectively improving the safety of coffee consumption.

[0027] In one embodiment, please refer to the following: Figure 2 and Figure 4The coffee grinding assembly 400 includes a coffee hopper 410 and a grinder 420. The coffee hopper 410 stores coffee beans, and the grinder 420 is connected to the workstation indexing plate 210. The grinder 420 is located at the grinding station of the workstation indexing plate 210, and its inlet is connected to the coffee hopper 410. In this embodiment, the coffee hopper 410 stores coffee beans, and the interior of the grinder 420 is connected to the coffee hopper 410. The grinder 420 grinds the coffee beans in the coffee hopper 410. Specifically, coffee beans are poured into the coffee hopper 410, which serves as a temporary storage container for the coffee beans. When coffee powder needs to be produced, the grinder 420 is activated to grind the coffee beans. The outlet of the grinder 420 faces the bottom of the housing 100. Before the grinder 420 is started, the rotating bowl 320 transfers the powder bowl 310 to the outlet of the grinder 420, so that the opening of the powder bowl 310 faces the outlet of the grinder 420, making it easier to load the coffee powder ground by the grinder 420 into the powder bowl 310.

[0028] In one embodiment, please refer to the following: Figure 2 and Figure 4 The tamping assembly 500 includes a tamping plate 510 and a tamping motor 520. The tamping motor 520 is connected to the workstation indexing plate 210 and is located at the tamping station of the workstation indexing plate 210. The telescopic end of the tamping motor 520 is connected to the tamping plate 510, which is used to tamp the coffee powder in the coffee bowl 310. In this embodiment, the tamping plate 510 serves as a component for compacting the coffee powder, and the tamping motor 520 provides power to the tamping plate 510. After the coffee bowl 310 moves from the grinding station to the tamping station, the coffee bowl 310 contains loose coffee powder. The tamping motor 520 drives the tamping plate 510 toward the opening of the coffee bowl 310, so that the tamping plate 510 can press the coffee powder in the coffee bowl 310, so that the coffee powder is compacted to form a coffee puck and prevent the coffee powder in the coffee bowl 310 from overflowing.

[0029] In another embodiment, the grinder 420 and the tamping motor 520 are combined into one, that is, the grinder 420 and the tamping motor 520 are combined to form a coffee grinder, which has both grinding and tamping functions. Specifically, after grinding is completed, the coffee powder is sent to the coffee bowl through the discharge channel, and then the tamping motor is turned on to drive the tamping plate to tamp the coffee powder in the coffee bowl.

[0030] In one embodiment, please refer to Figure 2The extraction assembly 600 includes an extractor 610 and a water pump 620. The extractor 610 is connected to the workstation indexing plate 210 and is located at the extraction station of the workstation indexing plate 210. The water pump 620 is connected to the extraction channel of the extractor 610 to inject extraction water into the powder bowl 310. In this embodiment, the outlet of the extractor 610 faces the opening of the powder bowl 310, and the inlet of the extractor 610 is connected to the water pump 620. The water pump 620 provides the water source required for the extraction operation of the extractor 610. The two ends of the extraction channel are the inlet and outlet of the extractor 610, respectively. The extractor 610 begins operation when the coffee bowl 310 moves to the extraction station. The extractor 610 injects water into the coffee bowl 310 to extract the coffee powder within, obtaining the desired coffee liquid. The coffee bowl 310 has a mesh structure with multiple small pores at its bottom; for example, the diameter of the mesh pores at the bottom of the coffee bowl 310 is smaller than the particle size of the coffee powder.

[0031] Further, please refer to Figure 5The extractor 610 includes an extraction gearbox 612, an extraction rotary motor 614, an extraction threaded wheel 616, a first spiral rod 618, and a second spiral rod 611. The extraction gearbox 612 is connected to the workstation indexing plate 210. The extraction threaded wheel 616, the first spiral rod 618, and the second spiral rod 611 are all disposed within the extraction gearbox 612. The extraction rotary motor 614 is connected to the extraction gearbox 612, and the shaft of the extraction rotary motor 614 is connected to the first spiral rod 618. The external thread of the first spiral rod 618 meshes with the external gear of the extraction threaded wheel 616 to rotate the extraction threaded wheel 616. The second spiral rod 611 has an extraction channel 602. The extraction gearbox 612 has an extraction rotating hole. The extraction threaded wheel 616 is sleeved on the second spiral rod 611, and the internal thread of the extraction threaded wheel 616 is screwed into the external thread of the second spiral rod 611 so that the second spiral rod 611 passes through the extraction rotating hole. In this embodiment, the extraction gearbox 612 serves as a fixed mounting body, and houses the extraction threaded wheel 616, the first helical rod 618, and the second helical rod 611. The extraction rotation motor 614 is fixed to the extraction gearbox 612, and provides rotational power to the first helical rod 618, causing the first helical rod 618 to drive the extraction threaded wheel 616 to rotate, thereby realizing the power transmission to the extraction threaded wheel 616. The extraction threaded wheel 616 is sleeved with the second screw rod 611, and the internal thread of the extraction threaded wheel 616 is screwed with the external thread of the second screw rod 611. When the extraction threaded wheel 616 rotates, it drives the second screw rod 611, causing the second screw rod 611 to rotate and rise along a plane perpendicular to the rotation of the extraction threaded wheel 616. This allows the second screw rod 611 to move away from or closer to the portafilter 310 through the extraction hole, adjusting the distance between it and the portafilter 310 to facilitate adjusting the water pouring height during extraction. Furthermore, the second screw rod 611 has the extraction channel 602 inside. The second screw rod 611 rotates simultaneously during its rising and falling, facilitating the even injection of water into all positions within the portafilter 310 during extraction, ensuring that the coffee grounds fully contact the water and improving the fineness of the extracted coffee.

[0032] Furthermore, please refer to Figure 5The extractor 610 further includes an extraction proportional gear 613, an extraction swing disk 615, and a first fixing rod 617 disposed within the extraction gearbox 612. The first fixing rod 617 is fixedly connected to the extraction gearbox 612, and the extraction proportional gear 613 is fixedly connected to the extraction swing disk 615. Both the extraction proportional gear 613 and the extraction swing disk 615 are sleeved on the first fixing rod 617. The extraction proportional gear 613 meshes with the external gear of the extraction threaded wheel 616. The extraction swing disk 615 has a first swing notch 604, which is used to mesh with the external thread of the first spiral rod 618. The diameter of the extraction swing disk 615 is larger than the diameter of the extraction proportional gear 613, and the diameter of the extraction swing disk 615 is smaller than the diameter of the extraction threaded wheel 616. The number of teeth of the extraction proportional gear 613 is smaller than the number of teeth of the extraction threaded wheel 616. In this embodiment, the extraction proportional gear 613 is located inside the extraction gearbox 612. The extraction proportional gear 613 is located between the extraction threaded wheel 616 and the first screw rod 618. The extraction proportional gear 613 and the extraction threaded wheel 616 form a combined gear. That is, the rotational speed of the extraction threaded wheel 616 is adjusted by the gear ratio of the extraction proportional gear 613 to the extraction threaded wheel 616. The extraction oscillating disk 615 is coaxially connected to the extraction proportional gear 613. The extraction oscillating disk 615 serves as a secondary speed adjustment component for the extraction threaded wheel 616. The first oscillation notch 604 is located at the edge of the extraction oscillating disk 615 and serves as an embedded groove for the external thread of the first spiral rod 618. When the first spiral rod 618 rotates, the extraction oscillating disk 615 drives the extraction proportional gear 613 to rotate at a certain angle. Specifically, by controlling the number of forward and reverse rotations of the extraction rotation motor 614, the number of forward and reverse rotations of the first spiral rod 618 is controlled. After reaching the specified number of forward or reverse rotations, rotation in the other direction can be performed, so that the first spiral rod 618 remains in contact with the extraction oscillating disk 615. That is, there is always a portion of the external thread of the first spiral rod 618 inside the first oscillation notch 604, which facilitates small-angle oscillation water spraying during the extraction process and avoids water splashing during extraction.

[0033] In another embodiment, the first helical rod 618 and the second helical rod 611 are perpendicular to each other.

[0034] In another embodiment, the extraction proportioning gear 613 is integrally formed with the extraction oscillating disk 615.

[0035] In another embodiment, the extractor and the tamping assembly are located at the same station to achieve coffee extraction and tamping in one step.

[0036] In another embodiment, please refer to Figure 2 The indexing assembly 200 further includes a water tank 230 and a flow meter 240. Both the water tank 230 and the flow meter 240 are mounted on the workstation indexing plate 210. The water tank 230 is connected to the water pump 620, and the flow meter 240 is used to detect the outflow rate of the water tank 230. In this embodiment, the water tank 230 serves as a water storage device, providing sufficient water for the extractor 610 to perform extraction. The flow meter 240 serves as a measuring device for the outflow rate of the water tank 230, facilitating real-time measurement of the outflow rate and thus enabling calculation of the remaining water level in the water tank 230.

[0037] In another embodiment, please refer to Figure 2 The indexing component 200 also includes a heating pot 250, which is connected to both the water tank 230 and the water pump 620. The heating pot 250 is used to heat the water flowing into the extraction channel 602. In this embodiment, the heating pot 250 serves as a heating source for the water output from the water tank 230. The heating pot 250 heats the water output from the water tank 230, and the switching on and off of the heating pot 250 facilitates the switching of hot extraction for coffee.

[0038] In one embodiment, please refer to Figure 6The slag discharge assembly 700 includes a slag discharge gearbox 710, a slag discharge rotating motor 720, a slag discharge threaded wheel 730, a third helical rod 740, and a fourth helical rod 750. The slag discharge gearbox 710 is connected to the workstation indexing plate 210, and the slag discharge gearbox 710 corresponds to the slag discharge workstation of the workstation indexing plate 210. The slag discharge threaded wheel 730, the third helical rod 740, and the fourth helical rod 750 are all disposed within the slag discharge gearbox 710. The slag discharge rotating motor 720 is connected to the slag discharge gearbox 710. The rotating shaft of the rotating motor 720 is connected to the third helical rod 740. The external thread of the third helical rod 740 meshes with the external gear of the slag discharge threaded wheel 730 to rotate the slag discharge threaded wheel 730. The slag discharge gearbox 710 has a slag discharge rotating hole. The slag discharge threaded wheel 730 is sleeved on the fourth helical rod 750. The internal thread of the slag discharge threaded wheel 730 is screwed to the external thread of the fourth helical rod 750 so that the fourth helical rod 750 passes through the slag discharge rotating hole. The fourth helical rod 750 is used to press down the rotating cup 320. In this embodiment, the slag discharge gearbox 710 serves as a fixed installation body. The slag discharge gearbox 710 houses the slag discharge threaded wheel 730, the third helical rod 740, and the fourth helical rod 750. The slag discharge rotating motor 720 is fixed on the slag discharge gearbox 710. The slag discharge rotating motor 720 provides rotational power to the third helical rod 740, so that the third helical rod 740 drives the slag discharge threaded wheel 730 to rotate, thereby realizing the power transmission to the slag discharge threaded wheel 730. The slag discharge threaded wheel 730 is sleeved with the fourth spiral rod 750. The internal thread of the slag discharge threaded wheel 730 is screwed into the external thread of the fourth spiral rod 750, so that when the slag discharge threaded wheel 730 rotates, it drives the fourth spiral rod 750, thereby causing the fourth spiral rod 750 to rotate and rise along a plane perpendicular to the rotation plane of the slag discharge threaded wheel 730. This allows the fourth spiral rod 750 to move away from or towards the rotating bowl 320 through the slag discharge hole, adjusting the distance between the rotating bowl 320 and the workstation indexing plate 210. This facilitates pressing down and moving the coffee bowl 310 away from the workstation indexing plate 210 before slag discharge, providing sufficient space for the flipping bowl 330 to flip the coffee bowl 310 so that the rim of the coffee bowl 310 can be flipped downwards, making it easier to pour out the coffee grounds inside the coffee bowl 310.

[0039] Further, please refer to Figure 6The slag discharge assembly 700 further includes a slag discharge proportional gear 760, a slag discharge swing disk 770, and a second fixed rod 780 disposed within the slag discharge gearbox 710. The second fixed rod 780 is fixedly connected to the slag discharge gearbox 710, and the slag discharge proportional gear 760 is fixedly connected to the slag discharge swing disk 770. Both the slag discharge proportional gear 760 and the slag discharge swing disk 770 are sleeved on the second fixed rod 780. The slag discharge proportional gear 760 meshes with the external gear of the slag discharge threaded wheel 730. The slag discharge swing disk 770 has a second swing notch 702, which is used to mesh with the external thread of the third spiral rod 740. The diameter of the slag discharge swing disk 770 is larger than the diameter of the slag discharge proportional gear 760, and the diameter of the slag discharge swing disk 770 is smaller than the diameter of the slag discharge threaded wheel 730. The number of teeth of the slag discharge proportional gear 760 is smaller than the number of teeth of the slag discharge threaded wheel 730. In this embodiment, the slag discharge proportional gear 760 is located inside the slag discharge gearbox 710. The slag discharge proportional gear 760 is located between the slag discharge threaded wheel 730 and the third helical rod 740. The slag discharge proportional gear 760 and the slag discharge threaded wheel 730 form a combined gear. That is, the rotational speed of the slag discharge threaded wheel 730 is adjusted by the gear ratio between the slag discharge proportional gear 760 and the slag discharge threaded wheel 730. The slag discharge swing disk 770 is coaxially connected to the slag discharge proportional gear 760. The slag discharge swing disk 770 serves as a secondary speed adjustment component for the slag discharge threaded wheel 730. The second swing notch 702 is located at the edge of the slag discharge swing disk 770 and serves as an embedded groove for the external thread of the third spiral rod 740. When the third spiral rod 740 rotates, the slag discharge swing disk 770 drives the slag discharge proportional gear 760 to rotate at a certain angle. Specifically, by controlling the number of forward and reverse rotations of the slag discharge rotation motor 720, the number of forward and reverse rotations of the third spiral rod 740 is controlled. After reaching the specified number of forward or reverse rotations, rotation in the other direction can be performed, so that the third spiral rod 740 and the slag discharge swing disk 770 remain in contact. That is, there is always a portion of the external thread of the third spiral rod 740 in the second swing notch 702, which facilitates the small downward pressure of the fourth spiral rod 750 during the slag discharge process and avoids damage to the rotating bowl 320.

[0040] In another embodiment, the third helical rod 740 is perpendicular to the fourth helical rod 750.

[0041] In another embodiment, please refer to Figure 6The slag discharge assembly 700 further includes a pressure relief push rod 792, which is detachably connected to the fourth spiral rod 750. The pressure relief push rod 792 is used to abut against the flipping bowl component 330. In this embodiment, the pressure relief push rod 792 serves as an extension of the fourth spiral rod 750 to increase the downward pressure distance of the fourth spiral rod 750, thereby adapting to the flipping of different sized powder bowls 310.

[0042] In another embodiment, please refer to Figure 2 The coffee grounds discharge assembly 700 further includes a coffee grounds collection box 794, which corresponds to the coffee grounds discharge station and is used to collect coffee grounds. In this embodiment, the coffee bowl 310 is oriented downwards during coffee grounds discharge, and the coffee grounds collection box 794 collects the poured-out coffee grounds, preventing them from contaminating other components.

[0043] In another embodiment, the workstation indexing plate is also provided with a slag discharge and cleaning channel, which is connected to the water pump and is located at the slag discharge workstation to inject water into the bottom of the overturned powder bowl, so as to facilitate cleaning the powder bowl.

[0044] In another embodiment, the water output by the water pump can be hot water heated by the heating pot 250. Before the coffee bowl is turned over, the water pump injects hot water into the mouth of the coffee bowl through the sludge removal channel to clean the coffee grounds and oils inside the coffee bowl.

[0045] In another embodiment, please refer to Figure 7 The slag discharge assembly 700 further includes a slag discharge return spring 796, which is sleeved on the indexing support column 220. One end of the slag discharge return spring 796 is connected to the indexing support column 220, and the other end of the slag discharge return spring 796 abuts against the side of the rotary cup 320 facing away from the workstation indexing plate 210. In this embodiment, the slag discharge return spring 796 is located on the indexing support column 220, between the bottom of the housing 100 and the rotary cup 320. After the rotary cup 320 is pressed down, the slag discharge return spring 796 is compressed. After slag discharge is completed, the downward pressure on the rotary cup 320 disappears, and the slag discharge return spring 796 releases its compression force, causing the rotary cup 320 to move upward to return to its original position, facilitating the next coffee brewing.

[0046] In another embodiment, please refer to Figure 2The coffee grounds discharge assembly 700 further includes a coffee grounds discharge air pump 798, which is located at the coffee grounds discharge station of the workstation indexing plate 210. The coffee grounds discharge air pump 798 is used to output high-pressure gas to the coffee bowl to blow the coffee grounds in the coffee bowl to the coffee grounds collection box 794. Before the coffee bowl is output with high-pressure gas by the coffee grounds discharge air pump 798, the coffee bowl tilting component 330 has already tilted the coffee bowl. That is, after the coffee bowl is tilted, the coffee grounds discharge air pump 798 begins to spray high-pressure gas into the coffee bowl.

[0047] In another embodiment, please refer to Figure 1 The housing 100 is provided with an operation panel 110, which is used to display the working status of the fully automatic coffee machine and is also used for touch control of the working mode of the fully automatic coffee machine.

[0048] In one embodiment, please refer to Figure 3The rotating bowl component 320 includes a rotating bowl box 322, a first rotating bowl gear 324, a second rotating bowl gear 326, a rotating bowl motor 328, a rotating bowl convex ring 321, and a rotating bowl rod 323. The rotating bowl box 322 is sleeved on the indexing support column 220. The first rotating bowl gear 324 and the second rotating bowl gear 326 are both disposed within the rotating bowl box 322. The first rotating bowl gear 324 and the second rotating bowl gear 326 mesh with each other. The second rotating bowl gear 326 is rotatably sleeved on the indexing support column 220. The rotating bowl motor 328 is connected to the rotating bowl box 322, and the rotating shaft of the rotating bowl motor 328 is connected to the first rotating bowl box 322. The rotating bowl gear 324 is connected; the rotating bowl convex ring 321 is connected to the second rotating bowl gear 326, the rotating bowl convex ring 321 is rotatably sleeved on the indexing support column 220, and the rotating bowl convex ring 321 is connected to the rotating bowl rod 323; the flipping bowl component 330 includes a flipping bowl motor 332 and a flipping bowl hoop 334, the flipping bowl motor 332 is connected to the end of the rotating bowl rod 323 away from the rotating bowl convex ring 321, the rotating shaft of the flipping bowl motor 332 is connected to the flipping bowl hoop 334, the flipping bowl hoop 334 is used to fix the powder bowl 310, and the rotating shaft of the flipping bowl motor 332 is perpendicular to the rotating shaft of the rotating bowl motor 328. In this embodiment, the rotating bowl box 322 serves as a fixed mounting box, meaning it is fixed to the indexing support column 220. The first rotating bowl gear 324, the second rotating bowl gear 326, and the rotating bowl motor 328 are all mounted on the rotating bowl box 322. The first rotating bowl gear 324 and the second rotating bowl gear 326 form a combined gear; specifically, the diameter of the first rotating bowl gear 324 is smaller than the diameter of the second rotating bowl gear 326. The rotating bowl motor 328 drives the second rotating bowl gear 326 to rotate via the first rotating bowl gear 324. The second rotating bowl gear 326 then drives the rotating bowl rod 323 to rotate via the rotating bowl convex ring 321, achieving a 360-degree full-angle rotation of the powder bowl 310, facilitating the movement of the powder bowl 310 to various workstations.

[0049] The flipping motor 332 serves as the power source for flipping the coffee bowl 310. The flipping ring 334 fixes the coffee bowl 310 in place. When the rotating rod 323 rotates the coffee bowl 310 to the coffee grounds discharge position, the flipping motor 332 rotates the flipping ring 334, causing the coffee bowl 310 on the flipping ring 334 to flip over, so that the mouth of the coffee bowl 310 faces downwards, making it easier to remove the coffee grounds inside the coffee bowl 310 in a timely manner.

[0050] In another embodiment, the transmission between the first rotary cup gear 324 and the second rotary cup gear 326 can also be achieved by a transmission chain.

[0051] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
