Description

Technical Field

[0001] The present invention relates to the technical field of coffee machines, and particularly to an intelligent hand-brewing coffee machine control system and a coffee machine. Background Art

[0002] In many cafes on the street, the drip-brewed coffee is made by using filters made of heat-resistant plastics, ceramics, metals, etc. The filter is placed on a cup or a collector, and a filter paper is put inside the filter. Then, the ground coffee bean powder is poured in, and a brewing pot filled with hot water is held by hand. The hot water in the brewing pot is poured along the center point of the coffee bean powder in the filter paper in a spiral motion from the outside to the inside to brew the coffee powder. However, the brewing method of drip-brewed coffee mainly uses manual operation of holding a brewing pot filled with hot water by hand. Therefore, the person brewing coffee must have rich experience and be proficient in the operation process to determine the taste and flavor of the drip-brewed coffee. If the person brewing coffee has insufficient experience and has poor control of the water flow rate and stability of the brewing pot filled with hot water, it will be determined that the coffee bean powder fails to achieve perfection after the stopped breathing process when brewed with hot water, so it is difficult to brew the coffee evenly, which affects the taste and aroma of the coffee. It is more difficult to control the quality of each cup of drip-brewed coffee. Even when there are many customers in the cafe, the staff will be under the pressure of having to quickly brew multiple cups of coffee. Often, in the rush, the brewing process of the drip-brewed coffee is shortened, or the water flow rate and stability of the brewing pot held by hand by the staff are poor, resulting in even more unstable quality of the brewed coffee, lower efficiency, and poor repeatability.

[0003] In the prior art, there are also coffee machines that simulate hand brewing. For example, a Chinese patent application with the publication number CN207384116U discloses a simulation hand-brewing device and a coffee machine thereof. The simulation hand-brewing device includes a main body, a spraying component, a water tank, and an orbital disk. A power source and a turntable driven by the power source are provided in the main body. The spraying component is slidably connected to the turntable and moves along the spiral orbit of the orbital disk under the drive of the turntable to simulate the hand-brewing process. Its structure is complex, and the spraying component needs to move along the spiral orbit, which is prone to jamming, resulting in uneven brewing. Moreover, its degree of intelligence is low, it cannot accurately restore the hand-brewing technique with high-precision trajectory, cannot accurately control the water temperature, and cannot perform ultrasonic oscillation on the brewed coffee to achieve different taste adjustments. Therefore, it needs to be improved. Summary of the Invention

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment 1: A control system for an intelligent hand-brewing coffee machine.

[0038] Refer to Figures 1 to 14As shown, an intelligent hand - drip coffee machine control system includes:

[0039] I. Cloud - based device management platform

[0040] The cloud - based device management platform is used to collect the working history of store devices and the idle status of devices for scheduling, realizing the whole process of automatically allocating orders to target hand - drip coffee machines after users place orders. The cloud - based device management platform is responsible for technique management, task assignment, data statistics, intelligent recommendation, etc. And it can connect the offline store docking system and the mobile application system.

[0041] The cloud - based device management platform also includes AI technique management, which supports users to input different hand - drip coffee techniques. According to the historical order - making suggestions of each technique, it understands and evaluates the techniques based on the AI large - model, and provides optimization suggestions. The cloud - based device management platform will also regularly provide maintenance suggestions based on the historical order - making records of the devices, provide device order - making statistical data, material preparation suggestions and other information to the store so that the store can manage the preparation materials in a timely manner.

[0042] By introducing an AI evaluation system, the cloud - based device management platform submits data to the server according to the historical brewing situation. After the AI model of the server evaluates the data, it sends instructions back to the water art control, enabling quick response during multiple uses. And it can obtain various latest techniques on the platform in real - time and enjoy various hand - drip flavors. The cloud - based device management platform can also deeply integrate with store data management, recommend suggestions, and regularly maintain the devices to keep them in the best state. Through the cloud - based device management platform, automatic order assignment can also be realized, reducing store management and improving order - making efficiency.

[0043] II. Intelligent control center

[0044] The intelligent control center is used to receive the unified scheduling of the cloud - based device management platform and can also be controlled through the function knobs on the device. After receiving the control instruction, the intelligent control center parses the corresponding brewing technique GCode code. The GCode code includes: water temperature, water flow rate, total outflow volume, waiting duration, movement trajectory, ultrasonic working power, and atmosphere light rendering data at specific times, synchronizes the signals between various components to make them work better in combination, and realizes the restoration of the whole process of hand - drip coffee.

[0045] The intelligent control center also includes a data acquisition and digitization module for the hand-brewing coffee process, which is used to deeply learn the techniques of hand-brewing coffee and provide a basis for the anthropomorphic brewing execution control module to follow in subsequent control. The working process of the data acquisition and digitization module for the hand-brewing coffee process is as follows: Use a 3D depth camera to collect data. First, perform image preprocessing to remove noise interference in the image. Identify the outline of the hand-pouring kettle through an edge detection algorithm, and then use a stereo matching algorithm to match the feature points in the left and right views to obtain the accurate three-dimensional coordinates of the hand-pouring kettle. Next, adopt a trajectory fitting algorithm. According to the three-dimensional coordinates of the hand-pouring kettle at different time points, fit a smooth moving trajectory curve. For example, a polynomial fitting algorithm can be used. By adjusting the order of the polynomial, the fitting curve can reflect the actual movement trajectory of the hand-pouring kettle as accurately as possible. During the fitting process, a filtering algorithm can also be combined to smooth the coordinate data and further improve the accuracy of the trajectory.

[0046] The data acquisition and digitization module for the hand-brewing coffee process can also simulate and measure the water output and water flow rate at each stage of hand-brewing coffee, providing a basis for the control of subsequent water processes for anthropomorphic brewing. The specific process is as follows: First, for the weight data collected by the electronic scale, arrange the data in chronological order according to the time stamp. Then, use the formula to calculate the water output, that is, the water output in a certain time period is equal to the weight measured by the electronic scale at the end of the time period minus the weight at the beginning. To calculate the water flow rate, according to the difference in water output between adjacent time points and the time interval, calculate the average water flow rate in different time periods through the formula "water flow rate = difference in water output / time interval". For the calculation of the instantaneous water flow rate, the differential idea can be adopted, and the average water flow rate in an extremely short time interval is approximately used as the instantaneous water flow rate at that moment.

[0047] The intelligent control center provides accurate data support for the hand-brewing equipment to restore the hand-brewing process through accurate recording and quantitative analysis of the hand-brewing coffee process. Transform the hand-brewing skills from traditional empirical descriptions into specific digital parameters, such as the movement trajectory of the hand-pouring kettle, water flow rate, water output at each stage, etc., so that the hand-brewing coffee process can be accurately replicated and inherited, solving the problem in the prior art that the hand-brewing coffee process cannot be scientifically and accurately recorded and restored, and meeting the needs of the coffee industry for the accurate inheritance of hand-brewing skills and the intelligent development of hand-brewing equipment.

[0048] III. Water Process Control Module

[0049] The water process control module is used to receive parameter instructions from the intelligent control center. By controlling the conduction state switching of the three-way solenoid valve and using the circulating water pump, combined with monitoring the states of the high and low water level float switches in the insulation water tank, as well as the data of the temperature sensor in the water tank and the inlet and outlet temperature sensors of the heating module, it adopts the PID control method for the heating module to realize the water circulation in the insulation water tank, ensure the uniform temperature of the liquid in the tank and reach the target set value, and at the same time ensure the constant temperature during single water outlet.

[0050] Referring to Figure 10 and Figure 11 As shown, the water process control module includes a water process control mechanism 7. The water process control mechanism 7 includes a water outlet pump 72, a heating module 75, a circulating water pump 77, a three-way solenoid valve 714 and an insulation water tank 717. Among them, the water outlet interface 71 of the water outlet pump 72 is connected to the water injection pipe 821 in the brewing actuator 8 through a silica gel hose 814. The water outlet of the circulating water pump 77 is connected to the water inlet of the heating module 75 through a pipeline. The water outlet of the heating module 75 is connected to the hot water interface 73 of the insulation water tank 717. The water outlet of the insulation water tank 717 is connected to the water inlet of the water outlet pump 72 through a pipeline. The first interface 712 of the three-way solenoid valve is connected to the external water inlet interface 710. The second interface 713 of the three-way solenoid valve is connected to the bottom water outlet interface 715 of the insulation water tank. The third interface 724 of the three-way solenoid valve is connected to the water inlet of the circulating water pump 77. During actual operation, the circulating water pump 77 is used to circulate and heat the water in the insulation water tank 717. The three-way solenoid valve 714 can input the water from the external water inlet interface 710 or the water in the insulation water tank 717 into the circulating water pump 77, and then be transported to the heating module 75 through the circulating water pump 77 for precise heating. The water in the insulation water tank 717 can be transported to the water injection pipe 821 in the brewing actuator 8 through the water outlet pump 72 for external water injection.

[0051] A high water level float switch 720 and a low water level float switch 721 of the heat preservation water tank are arranged in the heat preservation water tank 717. A steam outlet 718 of the heat preservation water tank is arranged at the top of the heat preservation water tank 717. The steam outlet 718 of the heat preservation water tank is connected to a steam outlet 79 installed at the bottom of the rack 1 through a pipeline. A drain interface 78 is arranged at the bottom of the heat preservation water tank 717. Among them, the high water level float switch 720 and the low water level float switch 721 of the heat preservation water tank are respectively used to keep the water level in the heat preservation water tank 717 stable. When the water level in the heat preservation water tank 717 is higher than the set water level, the high water level float switch 720 of the heat preservation water tank acts to cut off the water path to prevent the water level in the heat preservation water tank 717 from being too high. When the water level in the heat preservation water tank 717 is lower than the set water level, the low water level float switch 721 of the heat preservation water tank acts to cut off the water path to prevent the water level in the heat preservation water tank 717 from being too low. The steam outlet 718 of the heat preservation water tank is used to discharge the accumulated steam in the heat preservation water tank 717, and the drain interface 78 is used to empty the heat preservation water tank 717 when cleaning the heat preservation water tank 717.

[0052] A water outlet flowmeter 722 is installed on the pipeline connecting the water outlet 719 of the heat preservation water tank and the water inlet of the water outlet water pump 72. An inlet flowmeter 711 is installed on the pipeline connecting the first interface 712 of the three-way solenoid valve and the external water inlet interface 710. During actual operation, the set water outlet flowmeter 722 and the inlet flowmeter 711 can accurately measure the water outlet and inlet water volumes.

[0053] A heating module outlet water temperature sensor 74 is installed at the water outlet of the heating module 75, and a heating module inlet water temperature sensor 76 is installed at the water inlet of the heating module 75 to better control the heating temperature of the heating module 75. The control circuit 723 is installed on the rack 1 and is electrically connected to the water outlet water pump 72, the heating module 75, the circulation water pump 77, the three-way solenoid valve 714, and the heat preservation water tank 717 respectively. During actual operation, the water flow circulation in the heat preservation water tank 717 can be realized through the control circuit 723 to ensure that the liquid temperature in the tank is uniform and reaches the target set value.

[0054] The working principle of the water process control module is as follows:

[0055] 1) The three-way solenoid valve 714 is turned on, so that the first interface 712 of the three-way solenoid valve is directly connected to the third interface 724 of the three-way solenoid valve. At this time, the second interface 713 of the three-way solenoid valve and the solenoid valve water outlet end are in a cut-off state. The circulation water pump 77 starts to work, pumping the external water source from the external water inlet interface 710 and preheating it through the heating module 75.

[0056] 2) The control circuit 723 monitors the status of the high water level float switch 720 of the insulated water tank. When the switch is turned on, that is, the water level reaches the high water level line, the three-way solenoid valve 714 is turned off, so that the second interface 713 of the three-way solenoid valve is connected to the water outlet end of the solenoid valve, and the first interface 712 of the three-way solenoid valve is cut off from the third interface 724 of the three-way solenoid valve.

[0057] 3) At this time, the circulating water pump 77 is still in operation. Since the water outlet of the heating module 75 is connected to the hot water tank interface 73 at the upper left corner of the insulated water tank 717, and the bottom water outlet of the insulated water tank 717 is located at the lower right corner, a circulating water flow is formed in the insulated water tank 717. The temperature in the insulated water tank 717 is constantly circulating, and the temperature of the liquid in the insulated water tank 717 is uniform at all locations, which can be accurately detected by the internal temperature sensor 716 of the insulated water tank.

[0058] 4) When the insulated water tank 717 is in the water circulation state, the PID control of the heating module 75 is used to make the temperature in the insulated water tank 717 reach the target set value. The heating module inlet water temperature sensor 76 and the heating module outlet water temperature sensor 74 are combined as reference compensation (the ambient temperature may cause the pipeline circulation process to cool down).

[0059] 5) When the insulated water tank 717 is in a low water level state, the control circuit 723 controls the water outlet pump 72 to be in a stopped state, and a cycle of steps 1 to 4 is performed at this time to ensure the water level and temperature of the insulated water tank 717.

[0060] 6) When the target temperature is lower than the actual temperature of the insulated water tank 717, water is injected to mix with the hot water in the insulated water tank 717 to lower its temperature. (The water tank is designed with a large margin so that the mixing of hot and cold water will not overflow the tank). After mixing, the water circuit is still circulated to make the water temperature in the insulated water tank 717 uniform, and then heated to the target temperature.

[0061] This water process control module, by providing a circulating water pump 77, allows the water in the insulated water tank 717 to flow rapidly, ensuring uniform water temperature throughout the insulated water tank 717 and more accurate temperature measurement. Furthermore, the heating module 75 is provided with inlet and outlet water temperature sensors. When the heating module 75 is not operating (not in the heating state), the inlet and outlet water temperature sensors, combined with the internal temperature sensor 716 of the insulated water tank, can detect how much the temperature in the insulated water tank 717 may drop after passing through the pipe (generally 0.1 to 1°C, affected by the external ambient temperature), and compensate for the temperature of the insulated water tank 717, thereby facilitating precise control of the output water temperature. This water process control module also ensures a uniform and constant water temperature within the insulated water tank 717, achieving greater accuracy than traditional hand-pour coffee equipment and hand-pour coffee pots used by professionals. It also effectively compensates for the effects of ambient temperature, ensuring a more accurate temperature when the outlet water contacts the coffee grounds, thereby improving the hand-pour extraction rate.

[0062] 4. Humanized Brewing Execution Control Module

[0063] The human-like brewing execution control module receives parameter commands from the intelligent control center and uses an industrial-grade CoreXY stroke structure for trajectory control, accurately replicating the human-like brewing technique. The intelligent control center also analyzes and imitates similar techniques of various masters, generating deviation trajectories and allowing users to select flavors.

[0064] Reference Figure 13 and Figure 14 As shown, the anthropomorphic brewing execution control module includes a brewing actuator 8, which comprises a mounting frame mounted on the frame 1. Two X-direction linear guide rails 84 are mounted on the mounting frame, spaced apart and parallel to each other along the Y-direction. A Y-direction linear guide rail 819 is mounted between the two X-direction linear guide rails 84 via a slider. A motion module 815 is mounted on the Y-direction linear guide rails 819.

[0066] Referring to Figure 13 and Figure 14 As shown, the Y-direction driving device includes a first synchronous pulley 89, a second synchronous pulley 820, and a Y-direction driving motor. The first synchronous pulley 89 and the second synchronous pulley 820 are respectively installed at the front and rear ends of the Y-direction linear guide 819.

[0067] Referring to Figure 13 and Figure 14As shown in the figure, a first infrared limiter 810 is installed on the closed-loop stepper motor 81. A first reflection baffle 811 is installed on the back of the motion module 815. A second reflection baffle 816 is installed on the back of the Y-axis linear guide 819.

A full-color ambient light 813 is also installed at the bottom of the motion module 815 to enhance the atmosphere during the manual coffee brewing process of the device.

[0068] The working principle of this anthropomorphic brewing execution control module is as follows:

[0069] (1) The intelligent control center obtains the GCode motion trajectory from the cloud.

[0070] (2) According to the Gcode data, information such as temperature and water flow rate is synchronized to the water process control module, which controls the water flow, water volume, and water temperature.

[0071] (3) After the water process control module reaches the target temperature, it will send a synchronization signal. At this time, this anthropomorphic brewing execution control module performs a trajectory synchronization movement to complete the water injection trajectory process for the coffee powder.

[0072] The Gcode data includes: how many segments of water injection are required, and data such as the temperature, interval, flow rate, and water injection volume for each segment, fully replicating the master's manual brewing process. At the same time, the Gcode data includes the control of the ambient light, making the manual brewing process not monotonous and enhancing the atmosphere during the manual coffee brewing process of the device.

[0073] The structure of this anthropomorphic brewing execution control module is simple and reasonably designed, which can achieve precise positioning of the motion module 815 and the water injection pipe 821 in the X and Y directions, and realize the anthropomorphic trajectory movement process during hand-brewing coffee. During actual operation, the closed-loop stepper motor 81 in the X-direction driving device can drive the first synchronous belt 86 between the first driving idler pulley group 82 and the third driving idler pulley 87 to rotate forward or backward, and then drive the Y-direction linear guide rail 819 to move back and forth along the X-direction linear guide rail 84 through the second driving idler pulley 85, achieving precise movement of the Y-direction linear guide rail 819 in the X direction. The Y-direction driving servo motor in the Y-direction driving device can drive the first synchronous pulley 89 to rotate forward or backward, and then drive the motion module 815 installed on the transmission belt to move back and forth on the Y-direction linear guide rail 819 through the transmission belt, achieving precise movement of the motion module 815 in the Y direction. Through the cooperation between the X-direction driving device and the Y-direction driving device, the water injection pipe 821 installed on the motion module 815 can achieve precise positioning in the X and Y directions, realizing the anthropomorphic trajectory movement process during hand-brewing coffee.

[0074] V. Ultrasonic Generation Control Module

[0075] The ultrasonic generation control module is used to receive parameter instructions from the intelligent control center, drive the ultrasonic vibrator at the bottom of the container, and the high-frequency vibration energy generated by the vibrator is transmitted to the coffee liquid through the liquid medium, triggering the cavitation effect. By adjusting the intensity of the cavitation effect, the decomposition of bitter substances in the coffee liquid is realized, and at the same time, the release of flavor substances such as sourness is promoted, ultimately making the flavor of the coffee liquid meet the user's expectations.

[0076] Referring to Figure 6 and Figure 7 As shown, the ultrasonic generation control module includes an ultrasonic generation mechanism 3. The ultrasonic generation mechanism 3 includes a bottom plate 31. A limit groove 32 for placing the coffee pot 6 is arranged directly below the positioning through hole 22 provided on the filter cup placement support plate 2 on the bottom plate 31. An ultrasonic generator 34 is installed at the bottom of the limit groove 32, and a through hole 33 is arranged above the ultrasonic generator 34. During actual operation, the ultrasonic generator 34 can provide oscillations in different intensities and durations (millions of times per second) according to the situation of the brewed coffee liquid, causing the macromolecular structure in the coffee liquid to break and recombine, making the taste smoother.

[0077] The ultrasonic generator 34 in this ultrasonic generation mechanism 3 contains a 2.4 MHz high-frequency ultrasonic vibrator. When the coffee pot 6 is filled with coffee liquid, the vibrator transfers the potential energy to the coffee liquid through high-frequency oscillation. The coffee liquid generates a cavitation effect under the action of high-frequency ultrasonic vibration. This process promotes the decomposition of bitter substances such as chlorogenic acid in the coffee liquid, and at the same time accelerates the release of acidic components such as citric acid and malic acid, thereby enhancing the perception of sweetness and fruity aroma of the beverage.

[0078] In addition, before the ultrasonic generation control module works, various types of information about the coffee liquid in the target container (obtained through the interaction interface or communication method) can be collected first, such as coffee bean variety, origin, roasting degree, extraction method, and the user's taste preferences, etc. These information will be synchronously transmitted to the intelligent control center. The intelligent control center calculates the appropriate ultrasonic treatment parameters according to the preset professional parameter model of coffee and combines the coffee bean component decomposition data, including the driving power, working duration, and interval frequency of the ultrasonic oscillator. Then, the ultrasonic generation control module drives the ultrasonic generator 34 at the bottom of the coffee pot 6 to work according to the parameter instructions transmitted from the intelligent control center. The high-frequency vibration energy generated by the ultrasonic generator 34 is transmitted to the coffee liquid through the liquid medium, triggering the cavitation effect. By adjusting the intensity of the cavitation effect, the decomposition of bitter substances in the coffee liquid is achieved, and at the same time, the release of flavor substances such as sourness is promoted, ultimately making the flavor of the coffee liquid meet the user's expectations.

[0079] The control system of this intelligent hand-brewed coffee machine has the following remarkable advantages:

[0080] (1) The control system of this intelligent hand-brewed coffee machine can not only accurately simulate the manual brewing of coffee, but also achieve precise control of the water temperature for brewing coffee, improve the brewing quality, and increase the ultrasonic oscillation function, enabling the adjustment of different flavors.

[0081] (2) The control system of this intelligent hand-brewed coffee machine introduces an AI evaluation system in the cloud device management platform. According to the historical brewing situation, the data is submitted to the server, and the AI model of the server evaluates the data and then sends the instructions back to the water process control module. This enables quick response during multiple uses, and it can also obtain various latest techniques on the platform in real time, enjoy various hand-brewed flavors, and can deeply combine with the store data management, recommend suggestions, and perform regular maintenance on the equipment to keep the equipment in the best state.

[0082] (3) Through the innovative design of the water process control module, the control system of this intelligent hand-brewed coffee machine can achieve precise control of the water temperature for brewing coffee, improve the heating efficiency of the brewing water, ensure a constant temperature during single water output, and is more accurate than traditional hand-brewed coffee equipment and the hand-brewed coffee pots used by professionals. At the same time, it effectively compensates for the impact of the ambient temperature, making the temperature more accurate when the water contacts the coffee powder layer and improving the hand-brewed extraction rate.

[0083] (4) Through the innovative design of the anthropomorphic brewing execution control module, the intelligent hand-brew coffee machine control system can achieve the precise positioning of the water injection pipe installed on the motion module in the X and Y directions, realize the anthropomorphic trajectory movement process during hand-brewing coffee, and adopt an industrial-grade CoreXY stroke structure for trajectory control to accurately reproduce the master's hand-brewing technique. At the same time, the cloud device management platform can also analyze and imitate various masters' similar techniques, generate deviation trajectories, and allow users to select flavors.

[0084] (5) The intelligent hand-brew coffee machine control system can activate the ultrasonic generation control module according to its own taste. The ultrasonic generation mechanism can provide oscillations in different intensities and durations per second millions of times according to the situation of the brewed coffee liquid, causing the macromolecular structure in the coffee liquid to break and recombine, making the taste smoother.
