Description

Technical Field

[0001] The present invention relates to the technical field of beverage preparation equipment, and in particular to beverage preparation equipment and a debugging method thereof. Background Art

[0002] Existing beverage preparation equipment, especially fully automatic coffee machines, are generally preset with a grinding module, which grinds granular materials such as coffee beans through two blades to obtain powders such as coffee powder. The operating parameters of the grinding module, such as the gap between the blades and long-term grinding wear, affect the size of the powder particles obtained by grinding. After the powder is pressed with a preset pressure in the brewing component, a powder cake of a certain thickness will be obtained. Within a certain grinding time, due to the change in the particle size of the powder, the thickness of the pressed powder cake is different, resulting in changes in the channel density in the powder cake, thereby causing the liquid flow rate and extraction time through the powder cake to change, ultimately affecting the preparation efficiency and quality of the beverage. In daily use, beverage preparation equipment needs to periodically debug parameters such as the grinding module. Therefore, whether the grinding module parameter debugging process is simple and reliable affects the overall reliability of the beverage preparation equipment and also affects the user experience. Summary of the invention

[0003] The main purpose of the present invention is to provide a beverage preparation device and a debugging method thereof, aiming to provide a simple and reliable debugging method for a grinding module in the beverage preparation device.

[0004] To achieve the above object, the present invention provides a debugging method for a beverage preparation device, wherein the beverage preparation device comprises:

[0005] A grinding module, including a knife disc with adjustable grinding gap and a powder weight module;

[0006] The brewing module includes a water pipeline, a brewing cylinder arranged on the water pipeline, a water pump, a solenoid valve and at least one sensor. The debugging method of the beverage preparation equipment includes: presetting the powder weight, presetting the extraction time and presetting the total water intake.

[0007] The actual extraction time is obtained by the start-stop interval of the water pump or the solenoid valve under the total water inflow detected by the sensor;

[0008] By executing an extraction procedure, the actual extraction time and the preset extraction time are compared and processed, and when the actual extraction time is outside the deviation range of the preset extraction time, an instruction is given to adjust the blade grinding gap.

[0009] Optionally, the sensor is a flow sensor, and the preset total water intake volume is the total water volume required to perform one extraction procedure.

[0010] Optionally, the extraction program may be selectively provided with a pre-soaking program, wherein the total water intake may or may not include the running water volume of the pre-soaking program.

[0011] Optionally, a water cut-off time can be selectively set after the pre-soaking procedure; the preset and actual extraction times must be consistent and include or exclude the running time of the pre-soaking procedure and the water cut-off time after the pre-soaking, and the water cut-off time can be zero.

[0012] Optionally, the step of instructing the blade disc to adjust the grinding gap includes: when the actual extraction time is greater than the preset extraction time, increasing the grinding gap; or, when the actual extraction time is less than the preset extraction time, decreasing the grinding gap.

[0013] Optionally, the step of instructing to adjust the blade grinding gap includes: calculating the difference between the actual extraction time and the preset extraction time;

[0014] The invention relates to mapping association data of the adjustment amount of the difference, and obtains the target adjustment amount of the grinding gap according to the mapping association data; and adjusts the grinding gap according to the target adjustment amount.

[0015] Optionally, the beverage preparation equipment includes a control device electrically connected to the grinding module, the brewing module and the powder weight module, the control device includes a memory, a processor and a debugging program of the beverage preparation equipment stored in the memory and runnable on the processor, the preset powder weight, preset extraction time and preset total water intake are stored in the memory, and the processor performs comparison and instructions to execute blade grinding gap adjustment.

[0016] Optionally, the sensor includes a flow meter, which is arranged downstream of the brewing cylinder, wherein the flow meter can record the fluid flow rate of the water pipeline during extraction, wherein the change of the fluid flow rate curve during multiple repeated extraction processes prompts or executes the adjustment of the blade grinding gap.

[0017] A beverage preparation device comprises a brewing module, a water pipeline and a flow limiting hole arranged in the water pipeline. The beverage preparation device executes the debugging method of the beverage preparation device, and preferentially detects whether the flow rate of the flow limiting hole is within a normal value range.

[0018] Optionally, the beverage preparation device includes a grinding module and a brewing module, and the debugging method of the beverage preparation device includes:

[0019] Obtain the preset powder parameters, preset total water intake and blade grinding gap corresponding to beverage preparation;

[0020] Input a preset extraction time required for the beverage, start beverage preparation and obtain an extraction time that meets preset parameter conditions as a first extraction time, compare the first extraction time with the preset extraction time, and instruct to adjust the blade grinding gap according to the difference between the first extraction time and the preset extraction time;

[0021] Wherein, the powder parameters include preset powder weight and / or powder thickness.

[0022] Optionally, the step of instructing the blade disc to adjust the grinding gap includes: when the first extraction time is greater than the preset extraction time, increasing the grinding gap; or, when the first extraction time is less than the preset extraction time, decreasing the grinding gap.

[0023] Optionally, after the instruction adjusts the blade grinding gap, the beverage is prepared and the first extraction time is updated and compared with the preset extraction time. The instruction adjusts the blade grinding gap until the first extraction time is within the range of the preset extraction time.

[0024] Optionally, after the instruction adjusts the blade grinding gap, the grinding module executes a grinding program for a period of time to empty the residual powder in the grinding module, wherein the grinding program can be performed while the blade grinding gap is adjusted or after the blade grinding gap adjustment is completed.

[0025] Optionally, the preset extraction time and the blade grinding gap corresponding to the preset extraction time are stored in the beverage preparation device as reference parameters and are called during the operation of the beverage preparation device.

[0026] In the technical solution provided by the present invention, while ensuring that the actual powder weight in the beverage preparation process is equivalent to the preset powder weight and the total water intake is consistent, the correlation between the grinding gap and the extraction time is relatively high. Therefore, by comparing the actual extraction time with the preset extraction time, it is possible to directly determine whether the grinding gap needs to be adjusted and how to adjust it based on the comparison result, and the debugging process is relatively simpler and more reliable.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications 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).

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0044] See also Figures 1 to 10 The present invention provides a beverage preparation device. The beverage preparation device includes a body and a control device 100. The present design does not limit the specific type of the beverage preparation device, which can be any device or any product that can extract and brew materials to finally obtain beverages. Specifically, the beverage preparation device can be but is not limited to a coffee machine, a soymilk machine, a food processor, etc. Correspondingly, the materials involved in the present invention can be bean materials such as coffee beans and soybeans. However, for ease of understanding, the following embodiments are all described by taking the beverage preparation device as a fully automatic coffee machine as an example.

[0045] The machine body at least includes a housing with an inner cavity and a grinding module arranged in the inner cavity.

[0046] The grinding module may be, but is not limited to, a grinding cylinder and a grinding mechanism. A grinding chamber is formed inside the grinding cylinder; the grinding mechanism, for example, includes two relatively movable cutter discs and a first drive assembly that drives at least one cutter disc to move. A grinding space is formed between the two cutter discs for performing grinding and crushing operations such as piercing, grinding, and stirring of granular materials such as coffee beans. The grinding gap in the following embodiments refers to the width of the grinding space, that is, the distance between the two cutter discs. Among them, the inlet end of the grinding module, that is, the inlet end of the grinding cylinder, can be used to connect coffee beans to the above-mentioned grinding space; the outlet end of the grinding module, that is, the outlet end of the grinding cylinder, can discharge the ground coffee powder to the outside.

[0047] The grinding module can directly access the coffee beans from the outside of the housing. Or in one application, the machine body further includes a bean bin disposed in the housing. The bean bin is a container component that can provide a certain space to accommodate coffee beans. In actual application, the bean bin can be set to one or more according to actual needs. When there are more than one bean bin, each bean bin can be used to store the same coffee beans, or to store different types of coffee beans.

[0048] It should be noted that when there are multiple bean silos and different coffee beans are stored in each silo:

[0049] like Figure 4 As shown, in one embodiment, the number of grinding modules can be set to correspond to the bean bins one by one. It can be understood that the coffee beans stored in each bean bin can be used to prepare different types of beverages according to actual needs. At this time, different types of coffee beans and / or different types of beverages can be set to correspond to different grinding modules one by one, so that the blade parameters of the grinding module, such as the blade grinding gap, the blade grinding time, etc., correspond to the type of coffee beans and / or beverages and are well adapted to prepare better quality beverages. And when the blade parameters of each grinding module are adjusted in place, they can be directly called and used normally for preparing beverages after being stored, without the need to repeatedly adjust the blade parameters. In this way, it helps to simplify the adjustment procedure of the blade parameters, and makes the grinding accuracy of the grinding module relatively higher and the service life relatively longer.

[0050] Or in another embodiment, the same grinding module is compatible with at least two bean silos. Similarly to the above, the coffee beans stored in each bean silo can be used to prepare different types of beverages according to actual needs. At this time, different types of coffee beans and / or different types of beverages can correspond to different blade parameters of the same grinding module, such as blade grinding gap, blade grinding time, etc., so as to prepare better quality beverages. When it is determined that a beverage needs to be prepared, it is necessary to first adjust the blade parameters of the grinding module corresponding to the beverage; when it is determined that another beverage needs to be prepared, it is necessary to first adjust the blade parameters of the same grinding module again. In this way, it helps to simplify the number of grinding modules and simplify the structure of the whole machine.

[0051] The beverage preparation device may further include a brewing module arranged in the housing.

[0052] The brewing module may include, but is not limited to, a brewing cylinder and a brewing mechanism. The brewing cylinder may receive a required amount of coffee powder discharged from the outlet end of the grinding module, and then the coffee powder is extracted and brewed by the brewing mechanism to obtain a coffee drink. The brewing cylinder may be, for example, a powder bowl for receiving the powder discharged from the outlet end of the grinding module. The inlet end of the brewing module is also the inlet end of the brewing cylinder.

[0053] The brewing mechanism is mainly configured as a powder pressing module, a water supply component, etc. according to different brewing requirements. The brewing cylinder is provided with a brewing space for accommodating coffee powder. The powder pressing module includes two pistons arranged in the brewing cylinder and movable relative to each other along the inner wall of the brewing cylinder. The two pistons can move relatively close to each other or relatively far away from each other. A specific implementation includes: a lower piston that can move up and down is arranged in the brewing cylinder, and an upper piston that can move up and down is arranged outside the brewing cylinder. The powder pressing module drives the upper piston to move up and down, wherein the upper piston and / or the lower piston can be arranged at one end of the brewing cylinder to move relative to the brewing cylinder into the brewing cylinder or move out of the brewing cylinder to open the brewing cylinder, and the coffee powder enters the brewing cylinder through the open end or is discharged from the brewing cylinder.

[0054] In actual application, the brewing cylinder is movable to have a brewing position and a powder receiving position. The powder receiving position is the position when the brewing activity is located below the outlet end of the grinding module. When in the powder receiving position, the upper piston is separated from the brewing cylinder upward, so that the powder discharged from the outlet end of the grinding module directly or indirectly enters the brewing cylinder and is received by the lower piston. The brewing position is the position where the brewing cylinder mainly performs brewing and extraction operations. When in the brewing position, the upper piston can move into the brewing cylinder and move closer to or away from the lower piston, and then the powder received by the lower piston at the powder receiving position can be pressed to obtain a powder cake.

[0055] The water supply component can connect external water to the brewing cylinder, and under the combined action of heating and pressurization, the powder cake is brewed and extracted, and finally a beverage such as coffee liquid is obtained. The upper piston and / or the lower piston are separated from the brewing cylinder to discharge the extracted coffee powder cake. Among them, the brewing module is connected to the beverage outlet of the whole machine through, for example, a pipeline structure, and the prepared coffee beverage can be discharged to the outside.

[0056] In view of the above, the weight of the coffee powder discharged from the outlet of the grinding module is also the powder weight; the weight of the coffee liquid (extracted beverage) discharged from the outlet of the brewing module through the beverage outlet is also the liquid weight. There is no limitation on the measurement method of the powder weight and the liquid weight, which can be obtained by an external, universal weight sensor. Alternatively, it can be obtained by a pre-installed, dedicated weight sensor in the machine body.

[0057] Take the weight sensor as a preset and dedicated example for explanation:

[0058] The machine body may further include a powder weight module.

[0059] In one embodiment, the powder weight module is arranged between the outlet end of the grinding module and the inlet end of the brewing module. The inlet end of the powder weight module can be connected to the outlet end of the grinding module in an on-off manner, and the outlet end of the powder weight module can be connected to the inlet end of the brewing module in an on-off manner. The powder weight module can be fixedly installed in the housing, or it can be detachably installed in the housing. The powder weight module, the grinding module and the brewing module can be relatively fixed or relatively movable. When the powder weight module is moved close to the grinding module manually by the user or automatically driven by a preset power module:

[0060] If the inlet end of the powder weight module is connected to the outlet end of the grinding module, and the outlet end of the powder weight module is closed or disconnected from the inlet end of the brewing module, the powder weight module can receive and accommodate the coffee powder discharged from the outlet end of the grinding module, and perform the weighing function in real time or after the preset grinding time ends. At this time, the powder weight module is in the weighing mode. Of course, the powder weight module can also receive and accommodate the coffee powder discharged from the outlet end of the grinding module, but does not perform the weighing function. At this time, the powder weight module is in the non-weighing pre-receiving mode.

[0061] If the inlet end of the powder weight module is connected to the outlet end of the grinding module, and the outlet end of the powder weight module is connected to the inlet end of the brewing module, the powder weight module is set to a normally open state, so that when the powder is transported from the grinding module to the brewing module, the powder can pass through the powder weight module freely and unimpeded. The powder weight module mainly plays the function of transitioning powder and does not perform the weighing function. At this time, the powder weight module is in a non-weighing transition mode.

[0062] It should be noted that when the powder weight module is applied to the beverage preparation equipment, the powder weight module is placed in the casing as a modular component, and the powder weight module and the casing are quickly disassembled and assembled. An installation area is formed between the grinding module and the brewing module. When the powder weight module is installed in the casing, that is, it is installed in the installation space, and the installation space is filled. However, when the powder weight module is removed from the inside of the casing to the outside, the installation space is vacant: at this time, optionally, in one embodiment, the same detachable connection structure can be correspondingly provided at the powder weight module, the grinding module and the brewing module, and based on the detachable connection structure, the brewing module and the grinding module can be detachably connected to the casing respectively. In particular, when the powder weight module is removed from the outside of the casing to the outside, the position of the original powder weight module in the casing can be supplemented and replaced by moving the brewing module and / or the grinding module to avoid the above-mentioned installation space being vacant, so that the brewing module and the grinding module are as close as possible to avoid the powder material from scattering during the transfer process. Alternatively, in another embodiment, a detachable or integrated but deformable connecting structure may be provided between the grinding module and / or the brewing module. When the powder weight module is installed in the housing, the connecting structure is compressed and deformed to avoid forming the above-mentioned installation space; conversely, when the powder weight module is removed from the housing, the connecting structure is extended and deformed to connect the grinding module and the brewing module to avoid the above-mentioned installation space being vacant. The connecting structure may be a soft rubber channel, etc., and the specific form is not limited.

[0063] In view of the above, the beverage preparation device further includes an idling device 100. The control device 100 may be built into the housing or may be external to the housing. The control device 100 may be combined with a preset in-situ sensor to intelligently identify whether the powder reweight module is installed in the housing and whether it is installed in place in the housing, so that whether the powder reweight module is installed or not and whether it is installed in place or not can be flexibly selected, so that the beverage preparation device can be applied to different usage scenarios and realize different usage functions.

[0064] Of course, in one embodiment, the beverage preparation device can manually adjust whether the beverage preparation device is currently in the above-mentioned weighing mode or in the above-mentioned non-weighing mode. Among them, when the powder weight module is in the weighing mode, the powder weight module is generally installed in the casing, and is installed in place in the casing, and the weighing function is enabled. When the powder weight mode is in the non-weighing mode, it can be specifically but not limited to: the powder weight module is not installed in the casing; the powder weight module is installed in the casing but not installed in place; the powder weight module is installed in the casing and installed in place, but the weighing function is not activated, and it may currently be in the above-mentioned non-weighing pre-acceptance mode, or non-weighing transition mode, etc.

[0065] It should be noted that when the powder weight module is in a weighing state, the control device 100 first resets the weighing value of the powder weight module to zero before performing each powder weighing to minimize the impact of powder weight deviation caused by the powder weight module itself.

[0066] The body may also include a liquid weight module.

[0067] In one embodiment, the housing is generally provided with a beverage outlet at its front panel, and a receiving platform is provided below the beverage outlet. The beverage outlet can be connected to the outlet end of the brewing module. The receiving platform is provided with a water receiving trough for receiving the liquid discharged outward. The receiving platform can also be provided with a grille at the notch of the water receiving trough, and the grille can be used to support at least a container such as a cup, bottle, bowl, can, etc. without hindering the water receiving function of the water receiving trough. The container is used to hold the beverage discharged outward from the beverage outlet.

[0068] The liquid weight module generally includes a tray with an integrated weighing device, which can be placed on the receiving table, and when receiving the coffee liquid discharged from the beverage outlet, the weighing device measures the weight of the received coffee liquid in real time. The liquid weight module can be fixedly installed on the machine body or detachably installed on the machine body.

[0069] In one embodiment, the tray is flippably arranged relative to the front panel, so as to have an activated state when the tray is placed on the receiving table, and an inactivated state when the tray is close to and folded and stored at the front panel. The activated state and the inactivated state can be automatically identified by, for example, the control device 100 and a preset sensor in the beverage preparation device.

[0070] In addition, in one embodiment, the liquid weight module further includes a display component, which is electrically connected to the weighing device to display the measurement results of the weighing device. The display component can display any appropriate information according to actual needs, such as directly displaying the actual measurement data of the weighing device in real time, displaying the associated data obtained by converting the actual measurement data, and displaying the status information of the weighing function of the weighing device. The display component can be set on the tray, or the display component can be set separately from the tray, such as being placed externally on the housing.

[0071] Among them, when the liquid weight module itself forms a container for receiving liquid, if the current liquid weight module is in an enabled state, then each time before performing liquid weight measurement, the control device 100 first resets the weighing value of the liquid weight module to zero, so as to minimize the impact of powder weight deviation caused by factors of the liquid weight module itself.

[0072] When the liquid weight module itself is not equipped with a container for holding liquid, but instead holds liquid through an external container, if the current liquid weight module is in an enabled state, each time before performing liquid weight measurement, it first identifies whether there is a container placed on the tray of the liquid weight module. After detecting the weight of the container, the system will reset the weighing value of the liquid weight module to zero.

[0073] It can be understood that the above-mentioned operation of resetting the weighing value of the liquid weight module to zero can be performed before the system runs the beverage preparation mode, for example, before the brewing module starts the extraction operation, and the brewing module is controlled to start the extraction operation only after the weighing value is reset to zero.

[0074] In one embodiment, according to actual needs, the liquid weight module may further include a timer, which may be directly electrically connected to the weighing device, or indirectly associated with the weighing state of the weighing device by, for example, being electrically connected to the control device 100. The timer is configured to have a timing mode and a non-timing mode. When in the timing mode, the timer may record any desired time point and duration during the weighing process of the weighing device.

[0075] In particular, after the weighing value of the liquid weight module is reset to zero, the liquid weight module starts timing when it senses the weight of the extracted beverage. Usually, the liquid beverage extracted by the brewing module changes linearly when it falls into the liquid weight module. When the liquid weight module detects that the liquid weight in the container reaches a preset value, the liquid outlet pipeline is instantly cut off at the same time. Alternatively, the brewing module can be controlled to stop extraction (i.e., stop supplying water to the brewing cylinder), or the liquid outlet flow of the extracted beverage can be cut off or the water flow of the extracted beverage can be bypassed and discharged to achieve the purpose of stopping the liquid outlet.

[0076] It should be noted that, according to actual needs, the machine body may also include other devices, for example, when it is necessary to connect water to the brewing cylinder through a water supply component, the water supply component may include a water supply pipeline and a pump body, and the required valve body structure (such as a solenoid valve) may be provided at the interface of the water supply pipeline, and a pressure sensor for detecting water pressure, a flow sensor for detecting water flow, etc. may be provided at the required section of the water supply pipeline, without limitation.

[0077] Generally, there are many factors involved in the process of extracting a cup of high-quality coffee with beverage preparation equipment. Among them, the conventional parameters include the ratio between the weight of coffee powder and the weight of the extracted coffee liquid, which usually needs to be controlled within the range of about 1:2 (a certain range of weight deviation is allowed in actual conditions). Of course, the specific weight ratio of powder to liquid can be adjusted accordingly according to different coffee bean varieties, the taste of the beverage to be extracted, and other various factors.

[0078] According to different system configuration requirements and in order to realize the functions of various functional modules, the parameter values ​​involved in device detection include but are not limited to the following:

[0079] Table 1 Parameter information of grinding module

[0080] Knife head grinding clearance K The grinding time of the blade start-up is T1 Cutter grinding speed V Parameter Unit mm(mm) S (seconds) r / min (revolutions per minute) Parameter value range 0.01~20mm 0～15 600～2000

[0081] Among them, the parameter value of the blade grinding gap directly determines the particle size of the ground coffee powder, which causes the extraction time to change due to the particle size of the coffee powder when the coffee powder is extracted in the brewing module under the same extraction environment and conditions. In principle, the larger the grinding gap, the larger the particle size of the ground powder, the larger the gap between the particles under the same force in the brewing module, and the faster the water flow during extraction; the opposite is true.

[0082] Specifically in practical applications, preferably, the entire adjustment amount of the cutter disc grinding gap can be divided into multiple gear levels, for example, from -50 to 50, a total of 100 levels, each with a difference value of 0.01mm (the specific number of gear levels can be set by choice, and it is not necessary to set a constant gear), or it can be set to display the actual gap value in real time for adjustment.

[0083] The parameter information of the powder weight module includes: the preset powder weight after grinding by the grinding module can be set, that is, the weight of the powder that can be transferred to the brewing module for extraction. Among them, the parameter range of the preset powder weight setting can vary from 8g to 36g according to the needs of different beverages. After the powder weight module is set in the beverage preparation equipment and the powder weight module is enabled, there is no need to measure the weight of the ground powder by the grinding time of the blade disc. Therefore, after the powder weight module is set to enable the beverage preparation equipment, there is no need to detect and obtain the value of the grinding time of the blade disc. However, under certain functional requirements, the powder weight module can be enabled and the blade disc grinding time can be detected and obtained at the same time to achieve other additional functions. Please refer to the description of other paragraphs of the specification of the present invention for further information.

[0084] Table 2 Parameter information table of brewing module

[0085] information Parameter value range Parameter Unit Total water intake L 10～750 ml (milliliter) or tick Pressed powder thickness M 15～40 mm(mm) Pre-soaking time T1 0～10 s(seconds) Water stop time after pre-soaking Tm 0～10 s(seconds) Pressing pressure 15～70 kg

[0087] Parameter information Parameter value range Parameter Unit Preset extraction time T2 15～40 S (seconds) Preset Liquid Weight G2 16～60 g(gram)

[0088] When setting the blade parameters of the grinding module, you first need to adjust the value of the blade grinding gap. The value of the blade grinding gap determines the particle size of the coffee powder after being ground by the grinding module. Too large a particle size will cause the powder cake to be squeezed loosely and the extraction flow rate to be too fast, resulting in insufficient extraction. Too small a particle size will cause the powder cake to be over-squeezed and the extraction water flow to be too slow, resulting in excessive extraction. To obtain a suitable range of particle sizes, you need to adjust the value of the blade grinding gap to a reasonable range. However, with long-term high-speed grinding, the blade will gradually wear, causing the value of the grinding gap between the blades to change. At this time, the beverage preparation equipment needs to have the ability to identify the grinding gap, and be able to adjust the value of the blade grinding gap according to the obtained relevant parameter values ​​to maintain the stable quality of the produced beverages.

[0089] In order to stabilize the quality of coffee extraction and according to the golden cup principle of coffee extraction, to obtain a cup of coffee drink with perfect flavor, there are relevant weight values ​​and proportion requirements for the powder weight of the ground powder and the liquid weight of the extracted coffee liquid. Due to the setting of the powder weight module, the powder weight can be pre-set to allow the beverage preparation equipment to have more precise control over the powder weight during the operation of the equipment. In other implementations, the grinding time of the grinding module at each start and stop is measured to obtain information on the amount / weight of the ground powder.

[0090] Making espresso requires three stages: pre-soaking, flavor extraction, and end-of-extraction. The pre-soaking process is mainly used to remove carbon dioxide and improve extraction efficiency. Before extracting the coffee powder, pre-soaking the extruded powder cake with a certain pressure can effectively improve the flavor of the extracted coffee beverage. The pressure during pre-soaking is defined as the pre-soaking pressure. Before extraction, an appropriate amount of hot water is injected into the coffee powder cake with a certain pressure, so that the powder cake absorbs water in an appropriate amount to release more aroma and flavor. Furthermore, pre-soaking can make the powder cake fully moist, and the water flow during extraction can be better distributed. Of course, the pre-soaking pressure and pre-soaking time can be determined according to a variety of variables such as different coffee bean varieties or powder amounts or powder cake thickness, so the pre-soaking pressure can also be set to 0, that is, pre-soaking is performed using pressure-free water injection, and the pre-soaking time can also be set to 0, that is, the pre-soaking process is not performed.

[0091] Usually, the pre-soaking pressure is set not to be greater than the extraction pressure. The purpose of pre-soaking is to wet the powder cake, and it is not desired that the pre-soaking water flow out of the powder.

[0092] For example, when a powder weight module is pre-set in the beverage preparation device as described above, the powder cake parameter can be expressed by the powder weight obtained by the powder weight module or by the thickness of the powder cake. The powder cake refers to a block structure formed by the powder pressing module (for example, the upper piston and the lower piston are squeezed against each other) in the brewing cylinder after the ground powder is transferred to the brewing cylinder of the brewing module. The thickness of the powder cake can be detected by the movement stroke or distance of the upper piston and / or the lower piston, the sensing of a pre-set position sensor, etc.

[0093] In the beverage preparation device provided by the present invention, after the coffee powder is transferred to the brewing module, the upper piston and the lower piston can be used to extrude the powder with a preset pressure to form a powder cake of a certain thickness, and an extraction process is performed. The extraction process includes a pre-soaking program and an extraction program through a system preset or selectable program setting. An interval of time can be optionally set between the two time periods of running the pre-soaking program and the extraction program to give the pre-soaking program a certain immersion time. Among them, the amount of water used in the pre-soaking program and the extraction program is the total water intake L set in the system. Even if the pre-soaking function is turned off, the total water intake of the extraction is still L. It can be understood that the total water absorption of the coffee powder cake after being extruded and formed will not change much. Regardless of whether it has been pre-soaked, when the beverage preparation device needs to obtain a fixed weight of extraction liquid, the required total water intake L is within a fixed value range. Among them, the value of the total water intake L of the extraction process can be accurately measured by a flow meter, a flow valve, a timer, etc. Furthermore, in addition to configuring the pre-soaking program and the extraction program in the extraction process, other programs may be added, which are not limited here, but the total water intake L of the extraction process is a fixed set value.

[0094] In view of the above, the liquid weight module is in an enabled state, and when the liquid weight module measures that there is a container placed on the tray, the liquid weight module first performs an operation of returning the weighing value to zero. In a specific application of the beverage preparation device provided by the present invention, after a beverage is selected, it can be arranged that after the liquid weight module measures that there is a container placed in place and returns the weighing value to zero, the grinding module is started to grind the coffee beans; or the grinding module is first started to grind the coffee beans, and then the brewing module is started to perform the brewing procedure after confirming that the liquid weight module measures that the container is placed in place and returns the weighing value to zero. It is understandable that when the liquid weight module does not detect that there is a container (there is a change in weighing weight) placed on the tray, the grinding module and / or the brewing module will not be started. Of course, the above-mentioned weighing-related programs for the liquid weight module can also be selected to be turned off in the program settings of the beverage preparation device.

[0095] Among them, the total water intake L during the extraction process is to ensure the stability of the liquid output of the beverage after extraction, and can match other parameters to realize the detection and other functions of the beverage preparation equipment. It will be further explained in the embodiment of the present invention that until the extraction program is completed, the liquid weight detected by the liquid weight module no longer increases. At this time, the liquid weight module can accurately detect the exact liquid weight of the beverage extracted this time.

[0096] Furthermore, the liquid weight module can be used to measure the total water intake L under a fixed condition. At the moment of stopping the liquid discharge, the liquid weight module confirms the end of liquid discharge and obtains the total water intake L' consumed when the liquid weight is obtained when no continuous increase in liquid weight is detected, so as to perform data conversion and comparison with the preset total water intake L to determine whether the weight of the powder cake meets the requirements. If the actual water intake L' is greater than the preset total water intake L, it will warn that the amount of powder used for extraction is too large. If the actual water intake L' is less than the preset total water intake L, it will warn that the amount of powder used for extraction is too small.

[0097] The parameter values ​​obtained by the above-mentioned grinding module, powder weight module, and liquid weight module are all allowed to have a certain deviation range. When the values ​​fall within the deviation range, they are also identified as being in a normal working state. The relevant parameter values ​​involved in the present invention are defaulted to include their reasonable deviation range and the reasonable deviation of the system setting. The specific reasonable deviation range is not limited in the present invention and can be adjusted and set by itself according to different needs or completed in the beverage preparation equipment. The specific values ​​of the parameter values ​​and their deviation ranges involved in the present invention are schematic values ​​and are not used as a limitation on the values. Adjustment of the schematic values ​​is easy for researchers and developers in this field to think of, and cannot be used as a point to circumvent the present invention.

[0098] The beverage preparation device also includes an input module. The parameters that need to be input in advance can use the touch-controlled LCD display screen of the beverage preparation device of the present invention as an input module for preset parameters. In addition, they can also be input by a connected external device, such as a mobile phone, tablet computer, notebook, PDA and other mobile devices to form an input module. In a preferred embodiment, the beverage preparation device is provided with a touch-controlled LCD display screen, and the above parameters can be selectively presented on the display screen, and the parameter input can be realized by touch.

[0099] The beverage preparation device also includes a display control module. At least the display control panel of the display control module is exposed outside the housing so that the user can manually operate it. Among them, the control button part of the display control module constitutes the above-mentioned input module; the display part of the display control module can display preset numbers, texts, patterns, etc., to assist the user in understanding the status of the current parameter calibration, parameter debugging, normal use, etc. of the beverage preparation device. The control interface of the display control module will be specifically described below in conjunction with specific drawings.

[0100] In addition, based on any of the above embodiments, the beverage preparation device may be built-in or externally connected with a control device 100. The control device 100 is electrically connected to the grinding module, the powder weight module, the brewing module, the liquid weight module, and the like.

[0101] The control device 100 includes a memory 150 , a processor 110 , and a debugging program of the beverage preparation device stored in the memory 150 and executable on the processor 110 .

[0102] Reference Figure 2 , Figure 2 It is a structural diagram of a control device 100 of a hardware operating environment involved in an embodiment of the present invention.

[0103] like Figure 2 As shown, the control device 100 may include: a processor 110, such as a central processing unit 110 (CPU), a communication bus 120, a user interface 130, a network interface 140, and a memory 150. Among them, the communication bus 120 is used to realize the connection and communication between these components. The user interface 130 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface 130 may also include a standard wired interface and a wireless interface. The network interface 140 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (WIreless-FIdelity, WI-FI) interface). The memory 150 may be a high-speed random access memory 150 (Random Access Memory, RAM) memory 150, or a stable non-volatile memory 150 (Non-Volatile Memory, NVM), such as a disk storage device. The memory 150 may also be a storage device independent of the aforementioned processor 110.

[0104] Based on the different functional configurations of the beverage preparation equipment, corresponding sensors and functional modules can be set to measure or monitor the above parameter values, which can be transmitted to the processor 110 in real time or in preset settings to realize various functional combinations between different parameter modules.

[0105] Those skilled in the art will understand that Figure 2 The structure shown in the figure does not constitute a limitation on the control device 100, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0106] like Figure 2 As shown, the memory 150 as a storage medium may include an operating system, a network communication module, a user interface 130 module, and a debugging program for the beverage preparation device.

[0107] exist Figure 2 In the control device 100 shown, the network interface 140 is mainly used for data communication with the network server; the user interface 130 is mainly used for data interaction with the user; the processor 110 and the memory 150 in the control device 100 of the present invention can be set in the beverage preparation equipment, and the control device 100 calls the debugging program of the beverage preparation equipment stored in the memory 150 through the processor 110, and executes the debugging method of the beverage preparation equipment provided in the embodiment of the present invention.

[0108] It should be noted that the above structural composition does not constitute a limitation on the specific form of the beverage preparation device. In actual application, the beverage preparation device can be an automated beverage preparation device including the above modules, such as a coffee machine, a soybean milk machine, etc., with grinding function, brewing function and weighing function.

[0109] Take a beverage preparation device including a grinding module and a brewing module as an example: in one application, the grinding module and the brewing module can be assembled in the same housing, that is, integrated into a whole product, such as a fully automatic coffee machine.

[0110] Or in one application, the grinding module and the brewing module can be respectively assembled in two independent and different housings to constitute two independent products. For example, the beverage preparation equipment may include a bean grinder 200 and a brewer 300 (specifically, for example, a semi-automatic coffee machine) that are independently arranged and used in conjunction with each other. Among them, the bean grinder 200 mainly performs the grinding function and the powder weighing function, and the brewer mainly performs the brewing function, the liquid weight weighing function and the extraction time calculation function. At this time, when the above-mentioned powder weight module and liquid weight module are provided, the two can be selectively provided in the bean grinder 200, in the brewer 300, or independently provided compared to the bean grinder and the brewer according to actual needs.

[0111] See also Figures 9 and 10 A preferred embodiment of the present invention is to specifically express the beverage preparation equipment in the form of a grinder 200 and a brewer 300 being separately and independently arranged.

[0112] In this embodiment, the coffee bean grinder 200 and the coffee brewer 300 can be connected to each other by wire or wireless communication. The control device 100 can be selectively arranged in the coffee bean grinder 200, in the coffee brewer 300, or independently arranged compared to the coffee bean grinder and the coffee brewer according to actual needs.

[0113] Furthermore, the beverage preparation device can use a third-party external mobile device. The mobile device can be, but is not limited to, a mobile phone M1, a laptop computer M2, a tablet M3, a PDA, etc. The mobile device can be connected to the control device 100 by wire or wirelessly, which is equivalent to a wired or wireless communication connection with the grinder 200 and the brewer 300.

[0114] The mobile device may constitute the input module in the above or the following embodiments. At this time, the values ​​of all preset parameters of the grinder 200 and the brewer 300 are input by the mobile device and transmitted to the control device 100 for storage, call, and execution; or, an input module for inputting preset parameters may be provided in at least one of the grinder 200 and the brewer 300. The input module is different from the above mobile device. Two input modules may be provided, and they are respectively provided in the grinder 200 and the brewer 300, so as to input and manage the parameters of the grinder 200 and the brewer 300 respectively, and the values ​​of all preset parameters of the grinder 200 and the brewer 300 are input by the input module to the control device 100 for storage, call, and execution. Similarly to the above, the input module may be composed of a key module, a touch display module, a plug-in chip module, etc.

[0115] In view of the above, the bean grinder 200 and the brewer 300 can be independently arranged or installed in the same housing. Usually, a powder bowl is arranged between the bean grinder 200 and the brewer 300, and the powder bowl is used to hold the powder obtained by the grinding module and to provide space for brewing and extraction operations (equivalent to the above-mentioned brewing cylinder). The powder bowl can be reciprocated between the bean grinder 200 and the brewer 300, and the driving force during its movement can come from the user's manual control, or from the preset electric control power module. The powder ground by the bean grinder 200 is transferred to the powder bowl after the powder weight component is weighed, and the powder bowl is transferred to the brewer 300 for extraction. However, before the powder bowl receives the powder and transfers it to the brewer 300 for extraction, the powder in the powder bowl needs to be pressed. At this time, the above-mentioned powder pressing module needs to be set. In the embodiment of the present invention, the setting method of the powder pressing module is not limited, and manual pressing can be used, or a third-party powder pressing mechanism can be used. Preferably, a powder pressing module is provided in the grinder 200 or the brewer 300. After the powder weight component of the grinder 200 transfers the powder to the powder bowl, the powder pressing module is used to press the powder in the powder bowl and then transferred to the brewer 300 for extraction. Alternatively, the powder pressing module can be provided on the brewer 300, and the powder bowl that has received the powder is transferred to the brewer 300, and the powder is pressed first and then the brewing and extraction process is performed. The pressure of the powder pressing module on the powder bowl can be adjusted as a preset parameter.

[0116] Combined with the above description of the bean silo, it can be understood that one or more bean silos can be provided in the grinder 200. When there are several bean silos, each bean silo can store the same or at least partially different coffee beans. Each bean silo can be bound to a variety of different types of beverages, that is, the beverages of the various categories are all made from the beans in one bean silo. In addition, the bean silos can be respectively configured to correspond to the grinding module and / or the brewing module; or at least two bean silos can share one grinding module and / or brewing module.

[0117] Based on any of the above embodiments, one brewing machine 300 can be used with multiple bean grinders 200. Alternatively, one brewing machine 300 can be used with multiple bean bins in one bean grinder 200.

[0118] See also Figure 1 The present invention also provides a method for debugging a beverage preparation device. The beverage preparation device may be the beverage preparation device described in any of the above embodiments; or may be other beverage preparation devices.

[0119] The parameter values ​​obtained by the grinding module, powder weight module, and liquid weight module can be stored in association in the memory 150 of the control device 100, or can be stored separately and independently in the memory 150 of the control device 100. Of course, these values ​​can also be obtained by the user by inputting them on-site or in advance based on the above-mentioned method.

[0120] The above parameters can be based on the preset adjustment of the beverage preparation equipment before use, or can be real-time adjustment during the use of the beverage preparation equipment. Once the preset parameter values ​​are determined and multiple parameter values ​​are closed-loop, any change or modification of any parameter will break the closed loop formed by multiple parameter values ​​and require re-setting and adjustment.

[0121] In this design, a first implementation of the debugging method of the beverage preparation device includes:

[0122] Step S100: obtaining a preset powder weight, a preset liquid weight and a preset extraction time;

[0123] In this embodiment, there is no limitation on the method for obtaining the preset powder weight, the preset liquid weight and the preset extraction time. The three can be stored in association in the memory 150 of the control device 100, or can be stored separately and independently in the memory 150 of the control device 100. When needed, the processor 110 can directly call out the corresponding data from the memory 150.

[0124] Alternatively, the preset powder weight, preset liquid weight and preset extraction time can also be inputted by the user on site or inputted in advance. In this case, the user can be actively reminded to input the corresponding data based on the input module before or during the current debugging operation, or the user can actively input the corresponding data based on the input module. There are many ways to remind the user, which can be but not limited to a light signal emitted by a warning light, a prompt sound emitted by a buzzer, a message push received by a mobile device connected to the control device 100, etc.

[0125] Among them, the preset powder weight, preset liquid weight and preset extraction time are generally mapped one by one according to the needs of the user. For example, the three can be associated by coffee beans of the same weight. The preset powder weight and the actual powder weight and other weight values ​​described below can all be determined by the weight of the powder received by the powder weight module, or by the weight of the coffee powder discharged from the outlet of the grinding module after the preset weight of coffee beans is ground by the grinding module. The preset liquid weight and the actual liquid weight and other weight values ​​described below can all be determined by the weight of the liquid output received by the liquid weight module, or by the weight of the coffee liquid discharged from the beverage outlet after the preset weight of coffee beans is ground and extracted with a preset total water intake L. The preset extraction time and the actual extraction time described below generally refer to the time consumed by the extraction process, which is roughly the time consumed by the entire process of the coffee liquid being discharged from the beverage outlet.

[0126] In this embodiment, the preset powder weight, preset liquid weight, preset liquid discharge time and other adjustable parameters are all preset values; all parameter values ​​are within the preset value and its acceptable deviation range. At this time, the change in the value of the preset extraction time is a key parameter that determines the quality of beverage extraction.

[0127] It should be noted that there is no restriction on the timing of obtaining the preset powder weight, preset liquid weight and preset extraction time. They may be obtained simultaneously before executing the following step S200 or other operations, or may be obtained separately before executing the corresponding steps.

[0128] In addition to the method of directly inputting a specific value by the user, in one embodiment, at any time before starting the debugging program of the beverage preparation device, the preset extraction time can also be obtained by the following method:

[0129] In one application, the following steps may be performed:

[0130] Step S111: obtaining a preset powder weight and a preset liquid weight;

[0131] Step S121: running the beverage preparation mode, when the actual powder weight reaches the preset powder weight and the actual liquid weight reaches the preset liquid weight, obtaining the current extraction time;

[0132] Step S131: When the quality state of the prepared beverage does not meet the quality requirements, adjust the current corresponding extraction time, and repeatedly run the beverage preparation mode until the quality state meets the quality requirements, and use the current corresponding extraction time as the preset extraction time.

[0133] In this embodiment, both the preset powder weight and the preset liquid weight can be obtained by the user based on the input of the above-mentioned input module. Then, the beverage preparation device will be operated according to the data, and the beverage will be prepared. For the preparation of the beverage, the taste, quality and other quality status of the beverage can be confirmed by the user tasting or related sensor measurement, flavor data matching and other methods. When the quality status meets the preset quality requirements, it indicates that the current beverage preparation quality meets the quality requirements, and the extraction time corresponding to the current beverage can be used as the preset extraction time. However, when the quality status of the beverage cannot meet the preset quality requirements, it indicates that the current beverage preparation is not good, and the current corresponding extraction time can be adjusted directly or indirectly, and the beverage preparation mode can be re-run based on the same preset powder weight and preset liquid weight... Repeat the operation of the beverage preparation mode for multiple times until the quality status of the beverage obtained after a certain operation of the beverage preparation mode meets the quality requirements, and the corresponding extraction time can be determined as the preset extraction time and stored. At this time, the preset extraction time is also the extraction time obtained in the above-mentioned step S100 of the present invention.

[0134] It should be noted that when the quality of the beverage prepared each time does not meet the preset quality requirements, one of the ways to adjust the extraction time directly or indirectly is, for example, to increase or decrease the extraction time based on user experience or randomly. The second way is, for example, to obtain the extraction time difference between two adjacent extraction times, and adjust the blade grinding gap according to the extraction time difference. The specific method of adjusting the blade grinding gap according to the extraction time difference will be mentioned below and will not be repeated here.

[0135] Or in another application, the following steps may be performed:

[0136] Step S112: obtaining a preset powder weight, a preset liquid weight and a preset grinding gap of a cutter disc input by a user based on an input module;

[0137] Step S122: running the beverage preparation mode, stopping the liquid discharge when the actual powder weight reaches the preset powder weight and the actual liquid weight reaches the preset liquid weight, and obtaining the current extraction time;

[0138] Step S132: When the quality state of the prepared beverage does not meet the quality requirements, the blade grinding gap is adjusted according to the preset grinding gap, and the beverage preparation is repeated until the quality state meets the quality requirements, the currently corresponding grinding gap is used as the benchmark grinding gap, and the currently corresponding extraction time is used as the preset extraction time.

[0139] In this embodiment, the preset powder weight, preset liquid weight and preset grinding gap of the blade disc can all be obtained by the user based on the input of the above-mentioned input module. Then the beverage preparation equipment will be operated according to the data, and the beverage will be prepared. For the preparation of the beverage, the taste, quality and other quality status of the beverage can be confirmed by user tasting or related sensor measurement, flavor data matching and other methods. When the quality status meets the preset quality requirements, it means that the preset grinding gap of the current blade disc meets the requirements and can be used as a benchmark for the grinding gap in the subsequent debugging program. And the extraction time corresponding to the current beverage can be used as the preset extraction time. However, when the quality status of the beverage cannot meet the preset quality requirements, the current blade disc grinding gap needs to be adjusted, and after each adjustment of the blade disc grinding gap, the beverage preparation mode is repeatedly run to prepare a new beverage, and the quality status of the beverage is repeatedly confirmed until the quality status of the beverage meets the preset quality requirements.

[0140] It can be understood that when the preset extraction time that meets the quality requirements is obtained as described above, there is no restriction on the processing method of the extraction time. For example, it can be stored after confirmation by the user, or stored after manual input by the user, or the control device 100 automatically updates the data as a new benchmark value to replace the original benchmark value and then stores it.

[0141] Step S200: running the beverage preparation mode, stopping the liquid discharge when the actual powder weight reaches the preset powder weight and the actual liquid weight reaches the preset liquid weight, and obtaining the required actual extraction time;

[0142] In this embodiment, when the debugging instruction of the beverage preparation device is triggered, it can be associated with the beverage preparation mode. Among them, the triggering method of the debugging instruction is not limited. For example, it can be triggered by the user based on a preset button on the display and control module external to the housing, based on a preset program on a mobile terminal connected to the control device 100, by issuing a preset voice or performing a preset action, etc. According to actual needs, the debugging instruction can be subdivided into different debugging instructions corresponding to different debugging objects. In this embodiment, the debugging instruction is mainly used to debug the grinding gap between the two blades in the grinding module, and then achieve the purpose of adjusting the coarseness of the coffee powder obtained by grinding the grinding module, so as to ensure the quality of each cup of beverage produced.

[0143] The beverage preparation mode means that the whole machine executes the complete routine process of beverage preparation, including grinding, powder extraction, powder pressing, extraction and other operations, so that the final debugging result can be directly saved and adapted for the conventional beverage preparation mode.

[0144] It can be understood that the actual powder weight in step S200 can be measured by the powder weight module mentioned above, and the powder weight module can be detachably installed between the outlet end of the grinding module and the inlet end of the brewing module. Based on this, after running the beverage preparation mode and before executing the step of "stopping the liquid discharge when the actual powder weight reaches the preset powder weight and the actual liquid weight reaches the preset liquid weight, and obtaining the required actual extraction time", it also includes:

[0145] Step S230: Control the grinding module to start grinding and transfer powder to the powder weight module. When the weight of the powder received by the powder weight module reaches the preset powder weight, control the grinding module to stop working.

[0146] In this embodiment, the control device 100 first controls the grinding module to start running, and starts the powder weight module in weighing mode at the same time as the grinding module starts running, in advance or after a certain period of delay. In this way, when the grinding module grinds the coffee beans into powder and discharges it outward through its outlet, the powder weight module can simultaneously receive and measure the weight of the received powder, so that when the weight of the powder received by the powder weight module reaches the preset powder weight, the connection between the grinding module and the powder weight module is immediately cut off, and / or the grinding module is immediately controlled to stop working, so as to prevent the powder weight module from continuously receiving materials, resulting in overweight coffee powder.

[0147] Specifically, before executing the step of "controlling the grinding module to start grinding and transfer the powder to the powder weighing module" in step S230, the following steps may also be included:

[0148] Step S231: Detect whether the powder weight module is currently installed between the outlet end of the grinding module and the inlet end of the brewing module;

[0149] Step S232: when the powder weighing module is currently installed between the outlet end of the grinding module and the inlet end of the brewing module, detecting whether the powder weighing module is in a weighing mode; and,

[0150] Step S233: When it is confirmed that the powder weighing module has activated the weighing mode, the step of “controlling the grinding module to start grinding and transferring powder to the powder weighing module” is executed.

[0151] In this embodiment, steps S231 to S233 need to be completed before the outlet end of the grinding module starts to discharge the powder outward, that is, the grinding module conveys the ground coffee powder to the powder weighing module.

[0152] Since the powder weight module is detachably arranged, it has an installed state installed between the outlet end of the grinding module and the inlet end of the brewing module, and an uninstalled state moved out from between the outlet end of the grinding module and the inlet end of the brewing module. In step S231, firstly, based on a preset sensor device, it is possible to automatically detect and confirm whether the powder weight module is installed in the casing and whether it is installed in place in the casing. Among them, if the powder weight module has been installed in the casing, but is not installed in the designated installation area, or there is an abnormality in the installation direction, it means that it is not installed in place in the casing. The sensor device can be a force sensor, a photoelectric sensor, an image recognition sensor, etc. arranged at the powder weight module.

[0153] When it is confirmed that the powder weight module has been installed in the housing and is installed in place in the housing, it is necessary to confirm whether the powder weight module is in weighing mode. In view of the above, it can be seen that the powder weight module can optionally be provided with a weighing mode and a non-weighing mode, wherein when in the weighing mode, the powder weight module can measure the weight of the powder material received in transit; when in the non-weighing mode, the powder weight module can receive the powder material, or simply serve as a connecting pipeline for the powder material to flow from the outlet end of the grinding module to the inlet end of the brewing module.

[0154] When it is confirmed that the powder weight module has enabled the weighing mode, further, the weighing value of the powder weight module can be reset to zero first as described above. Then, in the process of the grinding module continuously discharging powder to the powder weight module, the weight of the powder material received by the powder weight module can be measured in real time to constitute the actual powder weight. When the actual powder weight of the powder material received by the powder weight module gradually increases to reach the preset powder weight value, the powder material of the preset powder weight is locked by controlling the grinding module to stop grinding and discharging powder, and / or by controlling the powder weight module to stop receiving powder, and the powder material is transferred to the brewing module for the brewing module to perform brewing and extraction operations on the powder material of the preset powder weight.

[0155] During the brewing and extraction process of the brewing module, the coffee liquid is discharged outward through the beverage outlet and the liquid is continuously discharged. At this time, the actual liquid weight is measured by a liquid weight module externally disposed at the beverage outlet of the beverage preparation device; the liquid weight module has an enabled state in which it moves to the bottom of the beverage outlet, and a storage state in which it moves out from the bottom of the beverage outlet, and the liquid weight module has preset timing mode and non-timing mode. Based on this, after running the beverage preparation mode, and before executing the step of "stopping the liquid discharge when the actual powder weight reaches the preset powder weight and the actual liquid weight reaches the preset liquid weight, and obtaining the required actual extraction time", it also includes:

[0156] Step S240: Control the brewing module to start working and discharge the extracted beverage to the liquid weight module, and when the liquid weight of the beverage received by the liquid weight module reaches the preset liquid weight, control the brewing module to stop working.

[0157] In this embodiment, for example, when the powder weight module has received the powder material that meets the preset powder weight, the brewing module is controlled to start running at the same time, before, or after a certain delay when the powder material is transferred to the brewing module by the powder weight module. After the above-mentioned extraction operations such as pressing into cakes and soaking, the beverage prepared by the brewing module is discharged outwardly through the beverage outlet, and is received by the liquid weight module and its weight is weighed.

[0158] Before the step of discharging the beverage outwardly through the beverage outlet, the step further includes:

[0159] Step S241: Detect whether the liquid weight module is currently in an enabled state;

[0160] Step S242: when the liquid weight module is in the enabled state, determining whether the timing mode is enabled; and,

[0161] Step S243: When the timing mode is enabled for the liquid weight module, the actual extraction time required from when the liquid weight module detects the presence of liquid weight until the actual liquid weight reaches the preset liquid weight is obtained.

[0162] In this embodiment, since the liquid weight module has an enabled state and a disabled state. When the liquid weight module is not needed, the liquid weight module is in a disabled state, for example, it is flipped from one side of the receiving platform to the front panel close to the casing, which does not hinder the normal liquid discharge of the beverage outlet and helps to simplify the space occupied by the receiving platform. In step S241, it is first necessary to confirm whether the liquid weight module is in an enabled state. Similarly, the confirmation process can be implemented based on a preset sensor device. The sensor device can be a force sensor, a photoelectric sensor, an image recognition sensor, etc. arranged at the powder weight module.

[0163] The actual extraction time can be obtained based on the detection of an external timer. However, in order to make the detection result of the actual extraction time more accurate, in this embodiment, a timer can be integrated in the liquid weight module, and the timer is associated with the state of the weighing device in the liquid weight module. In this way, in step S242, it is first necessary to confirm whether the timing mode of the liquid weight module is enabled.

[0164] Then, when the liquid weight module is in the enabled state and the timing mode is enabled, the liquid weight module starts to weigh and time the coffee liquid in real time until the actual liquid weight of the coffee liquid reaches the preset liquid weight, and then the timing ends.

[0165] Specifically, any of the above steps for obtaining the extraction time, such as the step for obtaining the preset extraction time in step S100 and / or the step for obtaining the actual extraction time in step S200, can be performed in various ways:

[0166] For example, one of the methods may specifically include:

[0167] Step S251: recording a first time point when the liquid weight module receives a first drop of beverage discharged outwardly through the beverage outlet;

[0168] Step S252: When the weight of the beverage received by the liquid weight module reaches a preset liquid weight, the liquid discharge is stopped and a second time point is recorded;

[0169] Step S253: Calculate the time interval between the first time point and the second time point as the extraction time.

[0170] In this embodiment, when the first drop of coffee liquid is discharged from the beverage outlet and received by the liquid weight module, the weighing device in the liquid weight module starts to record the actual liquid weight of the coffee liquid, and the timer in the liquid weight module starts to record the first time point. Then, when the coffee liquid continues to be discharged from the beverage outlet and received by the liquid weight module, the actual liquid weight recorded by the weighing device in the liquid weight module continues to change until the actual liquid weight reaches the preset liquid weight, that is, when the last drop of coffee liquid is discharged from the beverage outlet and received by the liquid weight module, the weighing device in the liquid weight module stops measuring, and the timer records the second time point. The duration between the first time point and the second time point is also the extraction duration (specifically, it can be the actual extraction duration).

[0171] It should be noted that the actual extraction time obtained by the above method does not include the pre-immersion time and the water-stop time after pre-immersion, because the liquid weight module cannot measure the parameters of the pre-immersion time and the water-stop time after pre-immersion.

[0172] Of course, there can be a second way: in order to achieve the same effect, other timing devices or flow meter devices are used to add the pre-soaking time and the water stop time after pre-soaking into the actual extraction time to control the time required for the overall brewing. This can also be used as another implementation method of the present invention for measuring the extraction time. The brewing module includes a water pipeline and a water pump arranged on the water pipeline as described above. The start time of the water pump and / or the start and stop time of the solenoid valve in the brewing water pipeline between the water pump and the brewing cylinder are used to calculate the extraction time (specifically, it can be the actual extraction time).

[0173] Specifically, it is described above that the water pump can choose to run the pre-soaking program and the extraction program, wherein a water outage time after pre-soaking can be optionally set between running the pre-soaking program and the extraction program. At this time, when the actual extraction time is calculated by the start and stop time of the water pump, the actual extraction time may include or exclude the running time of the pre-soaking program and the water outage time after pre-soaking. Then the preset extraction time corresponding to the actual extraction time needs to consistently include or exclude the running time of the pre-soaking program and the water outage time after pre-soaking to ensure accurate debugging operations. At this time, the water outage time can be any suitable natural number, including the value zero.

[0174] Step S300: Compare the actual extraction time with the preset extraction time, and when the extraction time difference between the actual extraction time and the preset extraction time exceeds a time difference threshold, instruct to adjust the blade grinding gap.

[0175] It can be understood that when the actual extraction time and the preset extraction time are both known, the relationship between the two may be as follows:

[0176] The time difference between the actual extraction time and the preset extraction time is within the time difference threshold. This includes the case where the actual extraction time is exactly the same as the preset extraction time, and also includes the case where the actual extraction time is not much different from the preset extraction time. This means that the current operation of the grinding module basically meets the preset, and the grinding gap remains within an appropriate range. The status quo can be maintained without adjusting the grinding gap.

[0177] The time difference between the actual extraction time and the preset extraction time exceeds the time difference threshold, and the actual extraction time is longer than the preset extraction time. The time difference between the actual extraction time and the preset extraction time exceeds the time difference threshold, which means that the current operation of the grinding module is abnormal. Without adding other abnormal parameter values, the finer the ground coffee powder particles, the less likely it is to form gaps for water to flow through after the coffee powder is pressed into a powder cake, resulting in a slower extraction speed and longer extraction time. Therefore, when the actual extraction time is longer than the preset extraction time, it indicates that the coffee powder currently ground by the grinding module is too fine, and the grinding gap needs to be appropriately increased.

[0178] The time difference between the actual extraction time and the preset extraction time exceeds the time difference threshold, and the actual extraction time is less than the preset extraction time. Similarly to the above, the time difference between the actual extraction time and the preset extraction time exceeds the time difference threshold, which means that the current operation of the grinding module is abnormal. Without adding other abnormal parameter values, the coarser the ground particles of the coffee powder, the easier it is for the coffee powder to be pressed into a powder cake to form gaps for water to flow through, resulting in faster extraction speed and shorter extraction time. Therefore, when the actual extraction time is less than the preset extraction time, it indicates that the coffee powder currently ground by the grinding module is too coarse, and the grinding gap needs to be appropriately reduced.

[0179] In view of the above, when the grinding gap is abnormally too large or too small, in order to better adjust the grinding gap, step S300 specifically further includes:

[0180] Step S310: when the extraction time difference between the actual extraction time and the preset extraction time exceeds the time difference threshold, obtaining mapping association data of the preset extraction time difference and the adjustment amount of the grinding gap;

[0181] Step S320: obtaining a target adjustment amount of a grinding gap according to the mapping association data and the current extraction time difference; and

[0182] Step S330: adjusting the grinding gap according to the target adjustment amount.

[0183] In this embodiment, the whole machine will store mapping association data of the extraction time difference and the adjustment amount of the grinding gap in advance. When either the extraction time difference or the adjustment amount of the grinding gap is known, the other can be accurately and uniquely queried through the mapping association data. The specific form of the mapping association data is not limited. According to actual needs, it can be a functional relationship, a dot graph or a line graph, or a table integrating a large amount of required data, so that the steps of repeatedly adjusting the grinding gap can be reduced as much as possible according to the mapping association data.

[0184] Preferably, after the beverage preparation equipment has completed the grinding gap adjustment, the actual extraction time has reached the preset extraction time range, and the grinding gap needs to be coarsened by 5 levels again, and then adjusted to 5 levels of fineness. During the adjustment of the grinding gap, the grinding module continues to work, and the residual powder in the grinding module and the powder ground by the coarsening of 5 levels are discharged from the grinding module, and the beverage is extracted again to further determine whether the extraction time is still within the preset extraction time range. If it is within the range, the calibration is completed. If the extraction time is not within the preset extraction time range, continue the above process to recalibrate. Among them, the gear or grinding gap after the coarsening can be set with a different value according to needs, which will not be repeated here.

[0185] Preferably, during the test and adjustment process, as long as the coarse and fine adjustment is performed, that is, the grinding gap is adjusted, if the powder particle size is adjusted coarsely, that is, the grinding gap adjustment is increased, the grinding gap adjustment motor works, and the grinding module does not need to work, that is, the powder is not ground; or the powder can continue to be ground. On the contrary, if the separation particle size is adjusted finely, that is, the grinding gap adjustment is reduced, the grinding gap adjustment motor and the grinding module need to be started at the same time, and the grinding module is in a continuous operation state. And as long as the grinding gap of the grinding module is adjusted, the residual powder in the corresponding grinding module needs to be drained first. When the grinding module continues to run until the preset operating conditions are met, it can generally be considered that the residual powder in the grinding module has been discharged. Among them, the implementation method of the present invention is that meeting the preset operating conditions includes reaching a preset operating time or obtaining a preset weighing powder weight value. For example, the grinding module can be started continuously for 8 seconds or the powder weight obtained by weighing the powder weight module reaches 15g, and then the powder in the powder weight module is emptied, and then the next cup of test or.

[0186] The mapping association data is obtained in any manner, and may be directly obtained by recording user experience, or may be experimental data obtained by a large number of experiments conducted in advance, or may be fitting data obtained by simulation, etc. The mapping association data is stored in the memory 150 of the control device 100, and may be retrieved and queried and compared when necessary.

[0187] Based on this, firstly, the step of calculating the current extraction time difference between the actual extraction time and the preset extraction time in step S310 is executed. When the current extraction time difference is determined, the target adjustment amount of the grinding gap associated with the current extraction time difference mapping can be obtained by querying and comparing the above mapping association data. Finally, the current gap value of the cutter disc is obtained, and the gap is adjusted according to the target adjustment amount based on the current gap value, so that the grinding gap can be adjusted to the desired position.

[0188] In the above, the instruction to adjust the cutter disc grinding gap includes manual input by the user, automatic updating and replacement of the cutter disc grinding gap parameters by the control device, etc.

[0189] In the technical solution provided by the present invention, during the beverage preparation process, while ensuring that the actual powder weight is equivalent to the preset powder weight, and the actual liquid weight is equivalent to the preset liquid weight, the correlation between the grinding gap and the extraction time is relatively high. Therefore, by comparing the actual extraction time with the preset extraction time, it is possible to directly determine whether the grinding gap needs to be adjusted and how to adjust it based on the comparison result, and the debugging process is relatively simpler and more reliable.

[0190] In addition, it should be noted that when the conclusion that "the extraction time difference between the actual extraction time and the preset extraction time does not exceed the time difference threshold" appears, the conclusion may be directly determined after executing step S200, that is, there is no abnormality in the blade disc grinding gap; the conclusion may also be determined when the blade disc grinding gap is initially abnormal during the execution of step S300, but after at least one adjustment of the grinding gap, the grinding gap is adjusted to the correct position. After the above conclusion that "the extraction time difference between the actual extraction time and the preset extraction time does not exceed the time difference threshold" appears, the following operations may also be performed:

[0191] Step S410: when the time difference between the actual extraction time and the preset extraction time does not exceed the time difference threshold, the grinding time required to reach the preset powder weight is obtained or converted into a grinding efficiency value, and recorded in real time;

[0192] Step S420: When the grinding time is higher than a preset time threshold or the grinding efficiency value is lower than a preset efficiency threshold, a prompt message for replacing the cutter disc is issued.

[0193] In this embodiment, when the extraction time difference between the actual extraction time and the preset extraction time does not exceed the time difference threshold, the beverage preparation mode is re-run, and in the process of grinding coffee beans by the grinding module, the actual grinding time required to obtain the preset powder weight is recorded. Then the theoretical grinding time associated with the preset powder weight is queried. According to the grinding time and the ground powder weight, the grinding efficiency can be calculated. When the grinding time or efficiency change triggers the preset threshold, that is, when the grinding time is higher than the time threshold or the grinding efficiency value is lower than the efficiency threshold, it indicates that the grinding module is abnormal and cannot meet the requirements. The possible reason is that the blade disc is excessively worn and is not suitable for continued use, and the blade disc needs to be replaced. At this time, the control device 100 will issue a prompt message for replacing the blade disc, wherein the grinding parameters for prompting the blade disc replacement include the grinding time or the grinding efficiency. Among them, the threshold range of the warning blade disc life is that the grinding time is higher than 50% of the preset time threshold or the grinding efficiency is lower than 50% of the preset efficiency threshold. The prompt message can be presented in any suitable way. For example, when a display control module is installed outside the casing, the prompt information can be displayed on the display screen in the form of characters, patterns, color blocks, etc. The prompt information can also be a light signal emitted by a warning light, a prompt sound emitted by a buzzer, a message push received by a mobile terminal connected to the control device 100, etc. The control device can be remotely monitored and the operating status of the powder weight module and the liquid weight module can be obtained, and the cause of the fault can be obtained when the powder weight module and the liquid weight module fail.

[0194] Based on the above embodiments, it can be understood that in the entire process of the beverage preparation mode, the beverage preparation device not only involves the blade, powder weight module, liquid weight module and other mechanisms, but also involves, for example, a water supply component, a powder pressing mechanism and the like. Therefore, in order to make the measurement results of steps S100 to S300 provided in this embodiment more accurate, in the process of running the beverage preparation mode, the following is also included:

[0195] Step A100: obtaining preset values ​​of operating parameters of the operating modules, wherein the operating modules include a grinding module, a brewing module, a powder weight module and / or a liquid weight module, and the operating parameters include the blade start grinding time and / or the total water intake L and / or the powder cake thickness; and,

[0196] Step A200: in the process of running the beverage preparation mode, obtaining the actual value of the operation parameter, and when the deviation between the actual value and the preset value exceeds the deviation threshold, stopping the operation and issuing a fault warning to the operation module associated with the operation parameter;

[0197] Step A300: During the operation of the beverage preparation mode, the actual value of the operation parameter is obtained, and when the deviation between the actual value and the preset value does not exceed the deviation threshold, the subsequent operation is continued.

[0198] In this embodiment, the operating parameters mainly refer to other parameter values ​​that may affect the correlation between the extraction time and the grinding gap in addition to the powder weight and liquid weight, and can be specifically set according to the actual preparation process, actual application scenario, actual preparation requirements, etc. In theory, during the entire process of executing the beverage preparation mode from the start of the grinding module to the discharge of the last drop of coffee liquid from the beverage outlet, abnormal operating parameters of all participating operating modules will directly or indirectly affect the correlation between the extraction time and the grinding gap to a certain extent, and reduce the accuracy of the grinding gap adjustment scheme determined by the extraction time. Therefore, the preset parameters can be, but are not limited to, the start-up grinding time of the blade, the total water intake L, the powder cake thickness M, etc.

[0199] By monitoring and obtaining the actual value of one or more operating parameters, the actual value is compared with the pre-stored preset value. When the actual value meets the corresponding preset value, that is, the operating parameter corresponding to the actual value is within the normal range, the remaining steps of step S200 and the subsequent step S300 can be continued; on the contrary, when the actual value does not meet the corresponding preset value, that is, the operating parameter corresponding to the actual value is abnormal, then it is necessary to first check the abnormality to ensure that the actual values ​​of the operating parameters meet the corresponding preset values, and then execute the remaining steps of step S200 and the subsequent step S300.

[0200] Specifically, the beverage preparation equipment of the present invention is provided with a powder weight module and a liquid weight module and their matching extraction time measurement, which can realize the grinding gap adjustment of the grinding module to affect the coarseness of the powder after grinding. After determining the powder weight, liquid weight and extraction time, the beverage preparation equipment can preset or set sensors, timers, flow meters and other equipment of each module connected to the processor 110 signal. Some of them can refer to the parameter types and value ranges of the above-mentioned modules.

[0201] Preferably, it includes calculating the start-up grinding time of a single grinding module based on the weight of powder detected by the powder weight module, and storing it as a preset value in the control device of the beverage preparation equipment. When the weighing data of the powder weight module and the preset data are within a controllable deviation range, but the actual start-up grinding time of the grinding module differs from the preset start-up grinding time outside the deviation range, it is inferred that the powder weight module is faulty, and an early warning prompt is given.

[0202] Preferably, it includes obtaining the total water intake L required for a single extraction based on the fixed powder weight, liquid weight and fixed extraction time, and storing it as a preset value in the beverage preparation equipment. When the weighing data of the liquid weight module and the preset data are within a controllable deviation range, but the actual total water intake deviates significantly from the preset total water intake L, it is inferred that the powder weight module has a fault, and an early warning is given. Furthermore, the powder cake thickness detection is added. If the powder cake thickness deviates, it is inferred that the powder weight module has a fault, and an early warning is given. If the powder cake thickness does not deviate, the total water intake deviates, and it is inferred that the liquid weight module has a fault, and an early warning is given. Before the fault detection prompts of the above-mentioned powder weight module and liquid weight module, it is necessary to detect that the grinding gap of the grinding module has not changed.

[0203] Preferably, the brewing cylinder of the brewing module can measure the thickness of the powder cake compressed in the brewing cylinder after completing the preset parameters of powder weight, liquid weight and fixed extraction time, and form a preset powder cake thickness as a preset value stored in the beverage preparation equipment. When the actual measured powder cake thickness is greater than the preset powder cake thickness, it is inferred that the powder weight module has a fault and an early warning prompt is given.

[0204] Furthermore, if the grinding gap of the grinding module is not adjusted, and the powder cake thickness and the powder weight values ​​detected by the powder weight module are abnormal, and the actual extraction time or extraction flow rate or extraction pressure data are abnormal, the system will push an abnormal reminder of the beans in the bean bin to prompt the operating user whether to replace or add new beans, and further prompt whether to re-calibrate the grinding gap to ensure that the actual extraction time or extraction flow rate or extraction pressure data are consistent with the preset values.

[0205] The above prompt information can be presented in any suitable manner. For example, when a display control module is installed outside the housing, the prompt information can be presented in the form of characters, patterns, color blocks, etc. on the display screen. The prompt information can also be a light signal emitted by a warning light, a prompt sound emitted by a buzzer, a message push received by a mobile terminal connected to the control device 100, etc.

[0206] It should be noted that the above-mentioned debugging method for the beverage preparation device can be performed synchronously when the beverage preparation device runs a preset working mode, and / or when the debugging program is called, and / or automatically after the beverage preparation device is restarted, without limitation.

[0207] In the beverage preparation equipment of the present invention, a liquid weight module is provided to accurately match the weight of the milk beverage to be mixed, so as to realize beverages mixed with coffee and milk, such as latte and cappuccino. For some beverages, the coffee liquid is extracted first and then the milk product is prepared, or the milk product is prepared first and then the coffee is extracted. It can be understood that no matter which one is prepared first, the preparation can use the superimposed measurement of the liquid weight module to achieve the precise ratio of the beverage, and the amount of milk used can also be accurately controlled to avoid waste and the phenomenon of unbalanced ratio in the produced beverage.

[0208] In view of the above, when the beverage preparation equipment includes multiple bean silos, and different bean silos are used to store different varieties of coffee beans. When the coffee beans in each bean silo are used as raw materials to run the beverage preparation mode, different beverages can be obtained one by one. It can be understood that the preparation process of each different beverage can be configured with the debugging program of the above beverage preparation equipment according to actual needs. When the coffee beans in different bean silos need to be replaced for extraction when running the beverage preparation mode, it is necessary to call different parameter settings for grinding, extraction and other processes, so that the preparation process of different coffee beans automatically matches the most suitable extraction parameters and processes. And when the debugging program corresponding to different coffee beans in different bean silos is completed, the above parameters corresponding to the debugging program can be stored in the memory 150, and no manual modification is required. When the beverage preparation mode is subsequently run in correspondence with different bean silos, the most suitable extraction parameters and processes after debugging can be automatically called.

[0209] The debugging method of the beverage preparation equipment provided by the present invention is used in a fully automatic coffee machine, or the debugging method of the beverage preparation equipment in which the grinder 200 and the brewing machine 300 are combined and linked is named CLS (Closed-Loop System) closed-loop control system technology, which is used for testing and adjusting beverage preparation equipment, and real-time automatic adjustment. One-click calibration can be achieved to meet the quality control of the equipment for each cup of beverage produced under long-term and high-frequency use.

[0210] The beverage preparation equipment of the present invention can be matched with multiple grinding modules. The CLS closed-loop system is associated with each bean bin or grinding module, and is associated with at least one of the multiple beverages set corresponding to the bean bin or grinding module. For example, after the extraction schemes associated with different types of beverages corresponding to the grinding module are automatically debugged, other types of beverages corresponding to the grinding module need to be readjusted.

[0211] After the CLS closed-loop control system function is integrated into the beverage preparation equipment in a programmatic manner, it can be turned on or off during the actual blade commissioning operation.

[0212] Furthermore, in traditional beverage preparation equipment, there is no matching relationship between the various modules of the equipment. The abnormality of a parameter may be caused by one of multiple components, but it is often impossible to quickly confirm which component caused the abnormality. This results in a waste of time in equipment maintenance, and the loss caused by the increase in idle time during equipment maintenance also increases accordingly.

[0213] After the beverage preparation equipment of the present invention is equipped with a powder weight module and / or a liquid weight module, and then matched with other internal parameter detections, it can achieve an intelligent leap in the beverage preparation equipment, and can perform intelligent monitoring on each module of the beverage preparation equipment. When an abnormality occurs in the corresponding parameter, the abnormal module can be quickly judged to achieve rapid and accurate identification.

[0214] The device debugging method of the present invention can be applied to the following scenarios:

[0215] 1. Active adjustment, mainly used for debugging, testing, factory parameter adjustment by R&D personnel, and preset parameter setting adjustment before use;

[0216] 2. When used for commercial purposes, such as self-checking before daily business operation or on-site maintenance and debugging by operation and maintenance personnel, the program can be set to execute the debugging method of the present invention at least once each time the machine is restarted;

[0217] 3. During daily use, due to the addition or replacement of new batches of coffee beans or different varieties of coffee beans, the particle size of the grinding module may be different and needs to be recalibrated.

[0218] 4. When used for commercial purposes, real-time monitoring and adjustment are required to ensure product stability.

[0219] See also Figure 3 As shown, at least part of the above parameter values ​​are adjustable parameters on the CLS control panel of the fully automatic coffee machine of the present invention. Specifically in one embodiment, the CLS control interface is divided into a plurality of areas Q:

[0220] The Q1 area is the bean bin prompt area. Different color blocks corresponding to different bean bins are displayed in this area. When one of the color blocks is lit up or the color or status changes significantly, it indicates that the currently adjusted CLS is bound to the bean bin.

[0221] The Q2 area is the CLS input (target value, i.e. the preset value mentioned above) area. In this area, the CLS input preset value can be, but is not limited to, the coffee liquid weight (i.e. the preset liquid weight), coffee powder weight (i.e. the preset powder weight), liquid discharge time (i.e. the preset extraction time), blade disc scale, etc. After the coffee liquid weight (i.e. the preset liquid weight), coffee powder weight (i.e. the preset powder weight), and liquid discharge time (i.e. the preset extraction time) are input, the above debugging program is started. Generally, the blade disc scale cannot be input, and the scale is 0 when CLS is started, which serves as the reference.

[0222] The Q3 area is the CLS test (actual value) area. In this area, the actual value of CLS input debugging can be but not limited to the coffee liquid weight (also known as the actual liquid weight), coffee powder weight (also known as the actual powder weight), liquid discharge time (also known as the actual extraction time), blade scale, etc., which are all actual data measured during each debugging. When the actual value is consistent with the above preset value (or within the preset tolerance range), the debugging operation stops.

[0223] The Q4 area is the debugging input key area, and the debugging times will be displayed above it.

[0224] The Q5 area is the beverage data area. In this area, the beverage data may be, but is not limited to, water volume, coffee powder volume, pre-infusion time, back pressure distance, bypass water volume, etc., which are associated with the beverage preparation mode. After the data in the above CLS test area is confirmed, it is automatically entered, updated or replaced.

[0225] The Q6 area is a display area for various beverage interfaces. When a difference occurs in this area, the debugging program will be automatically started, or a pop-up window prompt will appear for the user to press input to start the debugging program.

[0226] Q7 area is the CLS icon display area. When the CLS icon is displayed in this area, it means that the whole machine is currently in the CLS automatic debugging program.

[0227] Preferably, if the CLS program needs to be activated, it is necessary to ensure that the beans in the corresponding bean silo reach a certain quantity value to meet the amount required for the CLS program to complete a complete adjustment. Preferably, before starting the CLS program, the system prompts the operator to visually estimate the amount of beans based on a reference object, or to set a position sensor, weight sensor, etc. in the bean silo as a detection method.

[0228] In a preferred embodiment, the debugging method of the beverage preparation device may further perform the following steps:

[0229] Step S900: completing the setting input of the above-mentioned pre-parameters;

[0230] Step S901: Select the beverage to be tested, make N cups continuously, take the preset extraction time as the extraction average value, and the system identifies the numerical range of the standard deviation between the actual extraction time of the N cups and the preset extraction time;

[0231] Step S902: When the value of the standard deviation fluctuates too much, a confirmation message is pushed, and the operator is required to confirm whether it is abnormal.

[0232] In the debugging method program of the present invention, it can be set that after the extraction time difference between the actual extraction time and the preset extraction time is within the time difference threshold, a cup of beverage can be made to confirm that the extraction time difference between the actual extraction time and the preset extraction time is within the time difference threshold, so as to ensure the accuracy of the debugging result.

[0233] Furthermore, the beverage preparation device of the present invention is provided with a plurality of bean bins and a grinding module corresponding to each bean bin, wherein each bean bin can be bound to a plurality of different types of beverages, see the attached Figure 4 As shown, the beverage preparation device includes a touch-sensitive display operation interface (ie, the following control interface). The control interface can select a page for entering the beverage preparation device debugging. Figure 4 As shown, the D1 area in the control interface displays the various bean bins preset for the current beverage preparation device (for example, the left bean bin and the right bean bin); the D2 area displays the blade adjustment trigger buttons of each grinding module corresponding to each bean bin (for example, the left blade adjustment and the right blade adjustment), which can realize the manual adjustment of the blade parameters; the D3 area displays the CLS start and close trigger buttons of each bean bin; the D4 area displays the CLS calibration trigger buttons of each bean bin, which can be used to enter the CLS debugging interface. The selectable system settings can be, for example, Figure 5 As shown: When the debugging method of the corresponding bean silo or grinding module is enabled, it is not allowed to enter the program of manually adjusting the blade grinding gap, and a page prompt pops up, providing the option to confirm the exit of manual adjustment or to close the CLS debugging program.

[0234] You can select the bean bin or the beverage under the bean bin to enter the parameter debugging interface. You can select the corresponding bean bin or the grinding module that only corresponds to the bean bin to enter the debugging interface. Figure 8As shown, in the debugging page, the Y area displays a variety of drinks; the Y0 area displays the currently selected target drink; and the Z area is the various drink parameters corresponding to the currently selected target drink. Specifically, a variety of drinks corresponding to the bean silo are displayed on the page, and you can select drinks according to the bean silo, or match the bean silo according to the selected drink to trigger the corresponding debugging program. After the debugging is completed, all drinks under the bean silo or grinding module are locked, and the various different categories of drinks bound to each of the bean silos are compared with the selected debugged drink based on preset parameters, such as powder parameters and extraction parameters, to obtain the preset extraction time of the selected drink, so as to match the debugging method and directly reuse it for other types of drinks. Among them, any parameter adjustment will cause the online debugging program to fail,

[0235] Please refer to the attached Figure 6 As shown, after entering the beverage making interface, the Y area in the making interface displays the type of beverage; the F area displays the corresponding bean bin; and the Q area displays the corresponding CLS debugging. Among them, the Y, F and Q areas are associated and set as a block, and multiple blocks can be set at intervals in the debugging interface, and multiple blocks can be arranged linearly or in an array.

[0236] Specifically, a program-adjusted beverage or a beverage reused by a debugging method forms a badge Q around the icon Y of the beverage to indicate that the beverage has been debugged and can be used as a calibration of the blade grinding gap, wherein the badge can be at least one or a combination of graphics, colors, or dynamics. After selecting a beverage with a badge for extraction, the actual extraction time of the beverage with the badge is monitored during production, such as Figure 7 As shown, when the extraction time difference between the actual extraction time and the preset extraction time exceeds the time difference threshold, the page displays a prompt message.

[0237] The beverage cooking device of the present invention may also be equipped with a code scanning device.
