Description

Technical Field

[0001] This invention relates to the field of coffee machine technology, and in particular to a controllable rotary flavor blending brewing structure, and also discloses a control method for the controllable rotary flavor blending brewing structure. Background Technology

[0002] A coffee machine mainly consists of a spray nozzle, a filter cup, and a coffee pot, arranged sequentially from top to bottom. The filter cup holds coffee grounds / pucks, and the spray nozzle pours hot water into it, wetting and extracting the coffee grounds. The coffee drips from the filter cup's spout into the coffee pot on the base. As is well known, coffee machines have an extraction cycle, which is the time it takes for hot water to spray into the filter cup and extract the coffee grounds until the coffee has completely dripped into the coffee pot. This extraction cycle typically takes several minutes.

[0003] Chinese patent CN105147113A discloses a rotating shower head and a coffee machine, including a connecting base and a shower head installed on the connecting base. The connecting base is provided with a water inlet pipe and an impeller is provided inside the connecting base. The shower head is fixedly connected to the impeller. The water flow from the water inlet pipe can drive the impeller and the shower head to rotate relative to the connecting base. The water inlet pipe is connected to the water path of the shower head. By rotating the shower head, hot water is sprayed evenly to avoid local extraction and uneven extraction.

[0004] The problem with existing technology is that the concentration and flavor of the coffee liquid obtained at each stage of coffee powder extraction are inconsistent. The coffee liquid drips from the filter cup into the static coffee pot, and the landing point is concentrated in a fixed area, resulting in obvious layering and local differences in the coffee liquid in the pot. It is also necessary to manually stir, shake and mix the coffee liquid, which results in inconsistent coffee flavor and poor user experience.

[0005] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a controllable rotary flavor blending brewing structure that has a reasonable structure and solves the problem of inconsistent coffee flavors from the receiving end.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] The present invention discloses a controllable rotary flavor blending brewing structure, comprising a main body, wherein from top to bottom, a water outlet, an extraction component, and a base are arranged; the base is provided with a tray and a motor, the tray being rotatably positioned below the extraction component; the motor being drivenly connected to the tray; and a control module and a sensing component. The control module is connected to the sensing component and the motor via wiring. The sensing component is used to collect status information of the motor, tray, and water outlet and feed it back to the control module. The control module integrates an MCU processor, which is programmed with the SCFA algorithm. Based on the aforementioned status information, the MCU processor adjusts the motor's operating status in real time through the control module.

[0009] It is understood that the main body is the core or component of the coffee machine, used to arrange the water outlet, extraction assembly, and base from top to bottom. The water outlet is connected to the water supply module, allowing hot water to be sprayed onto the extraction assembly. The extraction assembly includes an extraction funnel and a support. The support is fixedly connected to the main body, and the extraction funnel is used to hold coffee powder or other beverage ingredients. The extraction funnel is detachably mounted on the support and positioned between the water outlet and the tray, on which a coffee pot is placed. The water outlet continuously sprays hot water into the extraction funnel, extracting the coffee to obtain concentrated coffee liquid, which drips from the outlet at the bottom of the funnel into the coffee pot on the tray.

[0010] Preferably, in this invention, the tray is rotatably mounted on the base, and the control module can control the motor to drive the tray to rotate according to a set speed. When coffee liquid drips from the extraction component into the coffee pot, the tray drives the coffee pot to rotate synchronously, preventing the coffee liquid from dripping into a specific area inside the pot, thus avoiding uneven concentration and flavor stratification.

[0011] Furthermore, the MCU processor is set as firmware on the control module. The SCFA algorithm is burned into the MCU processor. The sensing component can collect the status information of the motor, tray and water outlet. After the data is fed back to the MCU processor, the MCU processor can adjust the working parameters of the motor in real time based on the SCFA algorithm, so that the tray can perform actions including stopping, accelerating, decelerating, rotating forward, rotating backward and reversing and swinging back and forth, thereby avoiding the coffee liquid from dripping into a specific area.

[0012] Compared with existing technologies, this invention controls the coffee pot dynamically at the receiving end of the coffee liquid, avoiding uneven concentration. It can shake the coffee liquid in the coffee pot to disperse it evenly, improve the flavor integration, and effectively solve the problem of uneven flavor caused by the fixed drip filter of traditional coffee machines.

[0013] The MCU processor of this invention is based on the SCFA algorithm. According to the action data fed back by the sensing components, it automatically corrects the working parameters of the motor during the coffee brewing process by combining PID control, learns and simulates the flavor control style of hand-drip coffee, making the coffee machine more intelligent and automated, and improving the user experience.

[0014] According to the above scheme, the base is equipped with a cover plate, and the motor is located below the cover plate and fixedly connected to it. The output shaft of the motor is connected to the tray, thereby allowing the tray to be rotatably mounted on the cover plate. The base is designed to provide installation space for the motor and other components. The cover plate serves as a reference platform at the upper end of the base, and the tray is rotatably mounted on the cover plate. The motor can be directly connected to the tray via its output shaft to drive the tray to rotate on the cover plate. It is understood that the motor is a servo motor, with its output shaft directly connected to the tray, resulting in a relatively simple and compact structure. The control module connects to the motor's power supply circuit, and the MCU processor issues drive signals based on the SCFA algorithm. The control module adjusts the motor's input current, thereby regulating the tray's speed, rotation direction, and acceleration in real time.

[0015] According to the above scheme, the cover plate is equipped with a rotatable drive shaft, the upper end of which is connected to the tray, and the lower end of which is equipped with a driven gear. The motor is fixedly mounted inside the base, and the output shaft of the motor is equipped with a driving gear, which meshes with the driven gear. The meshing connection between the driving and driven gears establishes a transmission connection between the motor and the tray. This meshing connection can amplify and reduce the speed ratio, transmitting the motor's speed to the tray. It can be understood that the tray rotates at a low speed on the cover plate, and based on the transmission connection between the driving and driven gears, the tray's speed range can be controlled between 3-10 rpm.

[0016] According to the above scheme, the cover plate is equipped with a rotatable drive shaft, the upper end of which is connected to the tray, and the lower end of which is equipped with a driven pulley. The motor is fixedly mounted inside the base, and the output shaft of the motor is equipped with a driving pulley, which is connected to the driven pulley via a drive belt. It can be understood that the drive belt is a flexible drive belt, and the drive pulley and the driven pulley are connected by the drive belt, allowing the motor to drive the tray to rotate on the cover plate. Similarly, the speed ratio between the drive pulley and the driven pulley can be adjusted, allowing the motor to drive the tray to rotate at a low speed on the cover plate.

[0017] Furthermore, the active pulley and the passive pulley are connected by a flexible transmission belt. When the motor performs acceleration, stopping, and reversing actions, the transmission belt can provide cushioning to prevent the motor and the tray from being impacted, and in particular, to prevent the coffee pot on the tray from shaking severely.

[0018] According to the above solution, the tray is equipped with an anti-slip pad layer. This anti-slip pad layer increases the friction between the coffee pot and the tray, allowing the tray to rotate the coffee pot. The anti-slip pad layer is a conventional technology and will not be described in detail here. The advantage of the anti-slip pad layer is that the tray rotates the coffee pot at a low speed, eliminating the need for other clamping structures to secure the coffee pot. This simplifies the structure, makes it more convenient for users to pick up and put down the coffee pot, and improves the user experience.

[0019] According to the above scheme, the sensing component includes a first sensing layer and a second sensing layer. The first sensing layer is connected to the power supply circuit of the motor and the control module, and is used to collect real-time current / voltage data of the motor. The second sensing layer is installed on the motor and is connected to the control module through a line. The second sensing layer is used to collect the angular velocity of the motor output shaft. The first sensing layer is typically a sensing circuit integrated on the control module's circuit board, while the second sensing layer mainly consists of position sensors, which can use Hall effect sensors, encoders, etc.

[0020] According to the above scheme, the sensing component also includes a third sensing layer, which is disposed on the tray and connected to the control module via wiring. The third sensing layer is used to collect weight data on the tray. The third sensing layer is a piezoelectric sensor, disposed between the cover and the tray, or between the tray and the drive shaft, and is used to weigh the coffee liquid in the coffee pot on the tray and the amount of change thereof.

[0021] According to the above scheme, the sensing component further includes a fourth sensing layer, which is located at the water outlet. The fourth sensing layer is connected to the control module via a circuit and is used to collect the temperature T and flow rate F at the water outlet. The fourth sensing layer is a temperature sensor and a flow sensor.

[0022] A method for controlling a controllable rotary flavor-blending brewing structure, comprising the following steps:

[0023] Step 1: Start coffee preparation. The user selects a flavor strategy through the control module. The flavor strategy includes recipe parameters and speed constraints.

[0024] Step 2: MCU processor initialization. The fourth sensing layer collects the temperature T and flow rate F at the water outlet and feeds them back to the MCU processor. The MCU processor sets the initial speed of the motor / tray through the control module.

[0025] Step 3: The first sensing layer collects real-time current / voltage data of the motor, and the second sensing layer collects the angular velocity of the motor output shaft. The inertial / load feedback L is fed back to the MCU processor, and the third sensing layer collects the weight data on the tray and feeds it back to the MCU processor to calculate the liquid level H in the coffee pot.

[0026] Step 4: The MCU processor calculates the flow rate F, temperature T, liquid level H, and angular velocity. Inertial / load feedback L, based on the SCFA algorithm to calculate the target angular velocity ω t ;

[0027]

[0028] Where F is the real-time flow feedback value, F0 is the initial flow value, ΔT is the temperature change, ΔH is the real-time liquid level feedback value, H0 is the initial liquid level value, and K (k1, k2, k3) are weighting coefficients.

[0029] Step 5: The MCU processor collects the angular velocity in real time from the second sensing layer. PID control is executed, and the angular velocity variable Δω is calculated based on the SCFA algorithm;

[0030]

[0031] Where, ω t This is the real-time angular velocity feedback value, where ω is the initial angular velocity, and K (k p k i k d ) represents the weighting coefficient;

[0032] Step 6: The MCU processor calculates the drive current variable I′ based on the angular velocity variable using the SCFA algorithm;

[0033]

[0034] Step 7: The control module sends a drive signal based on the current variable I′ to adjust the motor's operating status in real time.

[0035] The working principle of this invention is as follows: At the start of coffee preparation, the user sets a flavor strategy according to their preferences. This flavor strategy forms the basic database of the control module, generated through experimental data collection, and can provide various coffee-making modes. The parameters corresponding to the flavor strategy include the outlet temperature, flow rate, time, and motor speed. The motor initially drives the tray to rotate at a fixed speed ratio, and hot water is input into the extraction component through the outlet. The sensing component collects flow rate F, temperature T, liquid level H, and angular velocity. The system collects data such as inertial / load feedback L and feeds it back to the MCU processor in real time. This data is dynamically changing. The MCU processor calculates the target angular velocity of the tray based on the SCFA algorithm and sends a drive signal to change the input current of the motor, thereby changing the tray's rotational speed. The SCFA algorithm does not simply rely on program settings; it calculates and updates the operating mode by sensing the dynamic data of the tray and water outlet in real time. This creates a two-way dependency between physics and algorithm, ensuring uniform and dynamic blending of the coffee liquid in the coffee pot. This high level of intelligence effectively enhances the user experience.

[0036] According to the above scheme, the drive signals include stop, acceleration, deceleration, forward rotation, reverse rotation, and reciprocating oscillation.

[0037] Understandably, during the coffee extraction process, the concentration and flavor of the coffee liquid obtained in the initial, middle, and final stages are inconsistent. The coffee pot, as the receiving end, is rotated at different speeds by the tray, which performs actions such as acceleration, deceleration, forward rotation, reverse rotation, and reciprocating swaying. This causes the coffee liquid inside the pot to form natural fluctuations. The fluctuations on the surface of the liquid are coupled with the rotation speed of the coffee pot, allowing the coffee liquid in the initial, middle, and final stages to be dynamically blended, thereby improving the flavor integration of the coffee liquid.

[0038] The present invention discloses a controllable rotary flavor blending brewing structure. The sensing component can collect the status information of the motor, tray and water outlet and feed it back to the control module in real time. The MCU processor, based on the SCFA algorithm, controls the working state of the motor. During the coffee brewing process, the coffee pot on the tray can rotate to avoid concentrated dripping of coffee liquid and improve the uniformity and flavor blending of the coffee liquid in the pot.

[0049] The technical solution of the present invention will be described below with reference to the accompanying drawings and embodiments.

[0050] Example 1

[0051] like Figure 1-2 As shown, the controllable rotary flavor blending brewing structure of the present invention includes a main body 1, which is provided from top to bottom with a water outlet 11, an extraction component (not shown in the figure), and a base 2. The base 2 is provided with a tray 21 and a motor 22. The tray 21 is rotatably disposed below the extraction component. The motor 22 is connected to the tray 21 for transmission. The structure also includes a control module 3 and a sensing component. The control module 3 is connected to the sensing component and the motor 22 through a circuit. The sensing component is used to collect the status information of the motor 22, the tray 21, and the water outlet 11 and feed it back to the control module 3. The control module 3 integrates an MCU processor 31, which is programmed with the SCFA algorithm. The MCU processor 31 adjusts the working state of the motor 22 in real time through the control module 3 according to the above status information.

[0052] It is understood that the main body 1 is the main body or component of the coffee machine, used to arrange the water outlet 11, extraction assembly, and base 2 from top to bottom. The water outlet 11 is connected to the water supply module and can output hot water to spray onto the extraction assembly. The extraction assembly includes an extraction funnel and a support. The support is fixedly connected to the main body 1, and the extraction funnel is used to hold coffee powder or other beverage ingredients. The extraction funnel is detachably mounted on the support and is located between the water outlet 11 and the tray 21, on which a coffee pot is placed. The water outlet 11 continuously sprays hot water into the extraction funnel, and the hot water extracts coffee to obtain concentrated coffee liquid, which drips from the outlet at the lower end of the funnel into the coffee pot on the tray 21.

[0053] Preferably, in this invention, the tray 21 is rotatably mounted on the base 2, and the control module 3 can control the motor 22 to drive the tray 21 to rotate according to a set speed. When coffee liquid drips from the extraction component into the coffee pot, the tray 21 drives the coffee pot to rotate synchronously, preventing the coffee liquid from dripping into a specific area inside the pot, thus avoiding uneven concentration and flavor stratification.

[0054] Furthermore, the MCU processor 31 is set as firmware on the control module 3. The SCFA algorithm is burned into the MCU processor. The sensing component can collect the status information of the motor 22, tray 21 and water outlet 11. After the data is fed back to the MCU processor 31, the MCU processor 31 can adjust the working parameters of the motor 22 in real time based on the SCFA algorithm, so that the tray 21 can perform actions including stopping, accelerating, decelerating, rotating forward, rotating backward and reciprocating swinging, thereby avoiding coffee liquid from dripping into a specific area.

[0055] Compared with existing technologies, this invention controls the coffee pot dynamically at the receiving end of the coffee liquid, avoiding uneven concentration. It can shake the coffee liquid in the coffee pot to disperse it evenly, improve the flavor integration, and effectively solve the problem of uneven flavor caused by the fixed drip filter of traditional coffee machines.

[0056] The MCU processor 31 of this invention is based on the SCFA algorithm. According to the action data fed back by the sensing components, it automatically corrects the working parameters of the motor 22 during the coffee brewing process by combining PID control, learns and simulates the hand-drip flavor control style, making the coffee machine more intelligent and automated, and improving the user experience.

[0057] The base 2 is provided with a cover plate 23. The motor 22 is located below the cover plate 23 and fixedly connected to it. The output shaft of the motor 22 is connected to the tray 21, so that the tray 21 is rotatably mounted on the cover plate 23. The base 2 is configured to provide installation space for the motor 22 and other components. The cover plate 23 serves as a reference platform at the upper end of the base 2. The tray 21 is rotatably mounted on the cover plate 23. The motor 22 can be directly connected to the tray 21 with its output shaft to drive the tray 21 to rotate on the cover plate 23. It is understood that the motor 22 is a servo motor 22. The output shaft of the motor 22 is directly connected to the tray 21, resulting in a relatively simple and compact structure. The control module 3 is connected to the power supply circuit of the motor 22. The MCU processor 31 issues drive signals based on the SCFA algorithm. The control module 3 adjusts the input current of the motor 22 to adjust the speed, rotation direction, and acceleration of the tray 21 in real time.

[0058] Furthermore, the active pulley 28 and the passive pulley 27 are connected by a flexible transmission belt 29. When the motor 22 performs acceleration, stopping, and reversing actions, the transmission belt 29 can provide cushioning to prevent the motor 22 and the tray 21 from being impacted, and in particular, to prevent the coffee pot on the tray 21 from shaking severely.

[0059] The tray 21 is equipped with an anti-slip pad layer, which increases the friction between the coffee pot and the tray 21, allowing the tray 21 to rotate the coffee pot. The anti-slip pad layer is a conventional technology and will not be described in detail here. The advantage of the anti-slip pad layer is that the tray 21 rotates the coffee pot at a low speed without the need for other clamping structures to hold it in place, resulting in a simpler structure and making it more convenient for users to pick up and put down the coffee pot, thus improving the user experience.

[0060] like Figure 7 As shown, the sensing component includes a first sensing layer 32 and a second sensing layer 33. The first sensing layer 32 is connected to the power supply circuit of the motor 22 and the control module 3, and is used to collect real-time current / voltage data of the motor 22. The second sensing layer 33 is disposed on the motor 22 and is connected to the control module 3 through a line. The second sensing layer 33 is used to collect the angular velocity of the output shaft of the motor 22. The first sensing layer 32 is typically a sensing circuit integrated on the circuit board of the control module 3, while the second sensing layer 33 is mainly a position sensor, which can use Hall elements, encoders, etc.

[0061] The sensing component also includes a third sensing layer 34, which is disposed on the tray 21. The third sensing layer 34 is connected to the control module 3 via wiring and is used to collect weight data on the tray 21. The third sensing layer 34 is a piezoelectric sensor, disposed between the cover plate 23 and the tray 21, or between the tray 21 and the drive shaft 24, and is used to weigh the coffee liquid in the coffee pot on the tray 21 and the change in weight.

[0062] The sensing component also includes a fourth sensing layer 35, which is located at the outlet 11. The fourth sensing layer 35 is connected to the control module 3 via a circuit and is used to collect the temperature T and flow rate F at the outlet 11. The fourth sensing layer 35 is a temperature sensor and a flow rate sensor.

[0063] A method for controlling a controllable rotary flavor-blending brewing structure, comprising the following steps:

[0064] Step 1: Start coffee preparation. The user selects a flavor strategy through control module 3. The flavor strategy includes recipe parameters and speed constraints.

[0065] Step 2: Initialize the MCU processor 31. The fourth sensing layer 35 collects the temperature T and flow rate F at the water outlet 11 and feeds them back to the MCU processor 31. The MCU processor 31 sets the initial speed of the motor 22 / tray 21 through the control module 3.

[0066] Step 3: The first sensing layer 32 collects real-time current / voltage data of motor 22, and the second sensing layer 33 collects the angular velocity of the output shaft of motor 22. The inertial / load feedback L is calculated and fed back to the MCU processor 31. The third sensing layer 34 collects the weight data on the tray 21 and feeds it back to the MCU processor 31 to calculate the liquid level H in the coffee pot.

[0067] Step 4: The MCU processor 31 calculates the flow rate F, temperature T, liquid level H, and angular velocity. Inertial / load feedback L, based on the SCFA algorithm to calculate the target angular velocity ω t ;

[0068]

[0069] ω t The expression for the function f(F,H,T) is derived, where F is the real-time flow feedback value, F0 is the initial flow value, ΔT is the temperature change, ΔH is the real-time liquid level feedback value, and H0 is the initial liquid level value;

[0070] K (k1, k2, k3) are weighting coefficients, which can be customized in the flavor strategy in step one to adjust the SCFA algorithm to achieve different flavor strategies.

[0071] Step 5: The MCU processor 31 collects the angular velocity in real time from the second sensing layer 33. PID control is executed, and the angular velocity variable Δω is calculated based on the SCFA algorithm;

[0072]

[0073] △ω is derived from the expression, where ω t This is the real-time angular velocity feedback value, where ω is the initial angular velocity;

[0074] K(k) p k i k d ) is the weighting coefficient, which can be customized in the flavor strategy in step one to adjust the SCFA algorithm to achieve different flavor strategies.

[0075] Step 6: The MCU processor 31 calculates the drive current variable I′ based on the angular velocity variable and the SCFA algorithm.

[0076]

[0077] Step 7: Control module 3 sends a drive signal based on the current variable I′ to adjust the working state of motor 22 in real time.

[0078] Specifically, the drive signals include stop, acceleration, deceleration, forward rotation, reverse rotation, and reciprocating oscillation.

[0079] like Figure 8 As shown, the working principle of this invention is as follows: When coffee preparation begins, the user sets a flavor strategy according to their preferences. This flavor strategy is based on the database of the control module 3, formed through experimental data collection, and can provide multiple coffee-making modes. The parameters corresponding to the flavor strategy include the temperature, flow rate, and time of the water outlet 11, as well as the rotational speed of the motor 22. The motor 22 initially drives the tray 21 to rotate at a fixed speed ratio, and hot water is input into the extraction component through the water outlet 11. The sensing component collects the flow rate F, temperature T, liquid level H, and angular velocity. The system collects data such as inertial / load feedback L and feeds it back to the MCU processor 31 in real time. This data is subject to dynamic changes. The MCU processor 31 calculates the target angular velocity of the tray 21 based on the SCFA algorithm and sends a drive signal to change the input current of the motor 22 to alter the rotational speed of the tray 21. The SCFA algorithm does not rely solely on program settings; it calculates and updates the operating mode based on the dynamic data of the tray 21 and the water outlet 11 fed back in real time by the sensing components. This creates a two-way dependency between physics and algorithms, ensuring uniform and dynamic blending of the coffee liquid in the coffee pot. This high level of intelligence effectively enhances the user experience.

[0080] Understandably, during the coffee extraction process, the concentration and flavor of the coffee liquid obtained in the initial, middle, and final stages are inconsistent. As the receiving end, the coffee pot is rotated at different speeds by the tray 21, which performs actions such as acceleration, deceleration, forward rotation, reverse rotation, and reciprocating swaying. This causes the coffee liquid in the coffee pot to form natural fluctuations, and the fluctuations on the surface of the liquid are coupled with the rotation speed of the coffee pot, so that the coffee liquid in the initial, middle, and final stages is dynamically blended, thereby improving the flavor integration of the coffee liquid.

[0081] Example 2

[0082] like Figure 3-4As shown, the difference between this embodiment and Embodiment 1 lies only in that the cover plate 23 is provided with a rotatable drive shaft 24, the upper end of which is connected to the tray 21, and the lower end of which is provided with a driven gear 25. The motor 22 is fixedly installed inside the base 2, and the output shaft of the motor 22 is provided with a driving gear 26, which meshes with the driven gear 25. The driving gear 26 and the driven gear 25 establish a transmission connection between the motor 22 and the tray 21 through their meshing connection. The meshing connection between the driving gear 26 and the driven gear 25 can amplify and reduce the speed ratio, transmitting the speed of the motor 22 to the tray 21. It can be understood that the tray 21 rotates at a low speed on the cover plate 23, and based on the transmission connection between the driving gear 26 and the driven gear 25, the speed range of the tray 21 can be controlled between 1-30 rpm.

[0083] Example 3

[0084] like Figure 5-6 As shown, the difference between this embodiment and Embodiment 2 is only that the cover plate 23 is provided with a rotatable drive shaft 24, the upper end of the drive shaft 24 is connected to the tray 21, and the lower end of the drive shaft 24 is provided with a driven pulley 27; the motor 22 is fixedly installed in the base 2, and the output shaft of the motor 22 is provided with a drive pulley 28, which is connected to the driven pulley 27 through a drive belt 29. It can be understood that the drive belt 29 is a flexible drive belt 29, and the drive pulley 28 and the driven pulley 27 are connected by the drive belt 29, so that the motor 22 can drive the tray 21 to rotate on the cover plate 23. As mentioned above, the drive pulley 28 and the driven pulley 27 can also adjust their speed ratio, so that the motor 22 can drive the tray 21 to rotate at a low speed on the cover plate 23.
