[0010] The present application relates to the technical field of beverage preparation apparatuses, and specifically relates to a beverage preparation apparatus and a control method, control device and storage medium thereof. BACKGROUND

[0011] The existing beverage preparation equipment, especially the full-automatic coffee machine, generally has a preset grinding module. The grinding module grinds the granular material such as coffee beans by two knife plates to obtain powder material such as coffee powder. The running parameters of the grinding module, such as the gap of the knife plates and the long-time grinding wear, affect the particle size of the powder material obtained by grinding. After the powder material is compressed in the brewing assembly by using the preset pressure, a powder cake with a certain thickness is obtained. In a certain grinding time, the particle size of the powder material changes, resulting in different thicknesses of the powder cake, which changes the channel density in the powder cake, thereby changing the liquid flow rate and extraction time through the powder cake, and finally affecting the preparation efficiency and quality of the beverage. During the daily use of the beverage preparation equipment, the parameters of the grinding module need to be adjusted periodically. Therefore, whether the grinding module parameter adjustment process is simple and reliable affects the overall reliability of the beverage preparation equipment and also affects the user experience. TECHNICAL PROBLEM

[0012] The main purpose of the present application is to provide a beverage preparation equipment and a control method, a control device and a storage medium thereof, aiming to provide a simple and reliable adjustment method of the grinding module in the beverage preparation equipment. TECHNICAL SOLUTION

[0013] To achieve the above-mentioned purpose, the present application provides an adjustment method of a beverage preparation equipment, the beverage preparation equipment comprising a grinding module and a brewing module, the grinding module comprising a knife plate with adjustable grinding gap; the adjustment method of the beverage preparation equipment comprising:

[0014] acquiring a preset powder weight, a preset liquid weight and a preset extraction time;

[0015] running a beverage preparation mode, stopping liquid output when the actual powder weight reaches the preset powder weight and the actual liquid weight reaches the preset liquid weight, and acquiring the actual extraction time required;

[0016] comparing the actual extraction time with the preset extraction time, and adjusting the grinding gap of the knife plate when the extraction time difference between the actual extraction time and the preset extraction time exceeds a time difference threshold. ADVANTAGEOUS EFFECTS

[0017] In the technical solution provided by the present application, the correlation between the grinding gap and the extraction time is high when the actual powder weight and the actual liquid weight in the beverage preparation process are equivalent to the preset powder weight and the preset liquid weight. Therefore, by comparing the actual extraction time with the preset extraction time, the adjustment of the grinding gap can be directly determined according to the comparison result, the adjustment process is relatively simpler, and the adjustment process is more reliable.

[0049] Please refer to FIGS. 1-26, the present application provides a kind of beverage cooking equipment. Beverage cooking equipment includes machine body and control device 100. The specific type of the design of beverage cooking equipment is not limited to any device or any product that can extract and brew material to finally obtain beverage. Specifically, the beverage cooking equipment can be but not limited to coffee machine, soybean milk machine, cooking machine etc., correspondingly, the material involved in the present application can be coffee beans, beans such as soybean material. For ease of understanding, the beverage cooking equipment in the following embodiments is taken as a full-automatic coffee machine as an example for description.

[0050] Wherein, machine body can include the shell formed with inner cavity and the powder supply module arranged in the inner cavity.

[0051] The powder supply module can include a powder storage module configured to store and discharge the powder. It can be understood that the powder storage module is a structure directly configured to store the powder. For example, the powder storage module can be formed with a powder storage cavity. The powder can be stored in the powder storage cavity in a loose manner, or in a capsule, a bag, or the like. When needed, the powder storage module directly discharges the powder.

[0052] The powder supply module can include a grinding module configured to grind the external beans into powder and discharge the powder. The grinding module can include, but is not limited to, a grinding cylinder and a grinding mechanism. The grinding cylinder is formed with a grinding cavity inside. The grinding mechanism includes, for example, two relatively movable cutting discs and a first driving assembly configured to drive at least one of the cutting discs. The grinding space between the two cutting discs is configured to perform grinding and crushing operations such as piercing, grinding, and stirring on the granular material such as coffee beans. The grinding gap in the following embodiments refers to the width of the grinding space, i.e., the distance between the two cutting discs. The inlet end of the grinding module, i.e., the inlet end of the grinding cylinder, can access the grinding space to input coffee beans. The outlet end of the grinding module, i.e., the outlet end of the grinding cylinder, can discharge the ground coffee powder.

[0053] The grinding module can directly access coffee beans from the outside of the machine shell. Alternatively, in an application, the machine body further includes a bean bin arranged in the machine shell. The bean bin refers to a container assembly configured to provide a space to store coffee beans. In actual applications, the bean bin can be arranged as one or several according to actual needs. When the bean bin is arranged as several, each bean bin can be used to store the same coffee beans, or to store different types of coffee beans.

[0054] It should be noted that when the bean bin is arranged as several and stores different coffee beans respectively:

[0055] As shown in FIG. 16, in an embodiment, the grinding module can be arranged as several corresponding to the bean bins. 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 arranged corresponding to different grinding modules, so that the parameters of the cutting discs of the grinding module, such as the grinding gap of the cutting discs, the grinding time of the cutting discs, etc., are well adapted to the type of coffee beans and / or beverages, so as to correspondingly prepare beverages with better quality. When the parameters of the cutting discs of each grinding module are calibrated, they can be directly called and normally used to prepare beverages after storage, without the need to repeatedly calibrate the parameters of the cutting discs. In this way, it helps to simplify the calibration procedure of the parameters of the cutting discs, and makes the grinding accuracy of the grinding module relatively higher and the service life relatively longer.

[0056] Or in another embodiment, the same grinding module is adapted with at least two hoppers. As described above, each hopper stores coffee beans of different types, and different types of coffee beans and / or different types of beverages can be corresponded to different parameters of the same grinding module, such as the grinding gap of the blade, the grinding time of the blade, etc., so as to correspondingly prepare beverages of better quality. When it is determined to prepare a beverage, the parameters of the blade of the grinding module corresponding to the beverage need to be adjusted first; when it is determined to prepare another beverage, the parameters of the blade of the same grinding module need to be adjusted again. In this way, the number of grinding modules can be simplified, and the structure of the whole machine can be simplified.

[0057] And / or, the beverage preparation device can comprise a brewing module arranged in the machine housing.

[0058] The brewing module can be, but is not limited to, comprising a brewing cylinder and a brewing mechanism. The brewing cylinder can receive the coffee powder of the required amount of powder discharged outwardly from the outlet end of the grinding module, and then the coffee powder is extracted and brewed by the brewing mechanism to obtain the coffee beverage. The brewing cylinder can be, for example, a powder bowl for receiving the powder discharged outwardly from the outlet end of the grinding module. The inlet end of the brewing module is also the inlet end of the brewing cylinder.

[0059] The brewing mechanism is mainly set as a powder pressing module, a water supply assembly, etc. according to different brewing requirements. The brewing cylinder is provided with a brewing space capable of accommodating coffee powder, and the powder pressing module comprises two piston members capable of moving relatively along the inner wall of the brewing cylinder. The two piston members can move relatively close to each other or relatively far away from each other. In a specific embodiment, a lower piston member capable of moving up and down is arranged in the brewing cylinder, and an upper piston member capable of moving up and down is arranged outside the brewing cylinder. The powder pressing module drives the upper piston member to move up and down, wherein the upper piston and / or the lower piston can be arranged to move into the brewing cylinder or move out of the brewing cylinder to open one end of the brewing cylinder relatively to the brewing cylinder. The coffee powder enters the brewing cylinder through the open end or is discharged from the brewing cylinder.

[0060] In actual application, the brewing cylinder is movable to have a powder receiving position and a brewing position. The powder receiving position is a position when the brewing cylinder is moved to be located below the outlet end of the grinding module. When the brewing cylinder is in the powder receiving position, the upper piston is moved away from the brewing cylinder upwardly, so that the powder discharged outwardly from the outlet end of the grinding module directly or indirectly enters the brewing cylinder and is received by the lower piston member. The brewing position is a position where the brewing cylinder mainly performs brewing and extraction operation. When the brewing cylinder is in the brewing position, the upper piston can move into the brewing cylinder and move close to or away from the lower piston member, so as to press the powder received by the lower piston member at the powder receiving position and obtain a powder cake.

[0061] The water supply assembly can introduce external water into the brewing cylinder to wet the powder and / or cake in the brewing cylinder. When water needs to be introduced into the brewing cylinder by the water supply assembly, the water supply assembly can include a water supply pipeline and a pump body, a required valve structure (such as an electromagnetic valve) can be arranged at the interface of the water supply pipeline, and a pressure sensor for detecting water pressure, a flow sensor for detecting water flow, etc. can be arranged at a required pipe section of the water supply pipeline, without limitation.

[0062] When a conventional brewing and extraction process is performed, the water supply assembly can directly introduce high-temperature hot water or obtain high-temperature hot water under the action of the heating module to achieve brewing and extraction of the cake, and finally obtain a beverage such as coffee liquid. The upper piston and / or the lower piston is separated from the brewing cylinder to discharge the extracted coffee cake. The brewing module is connected in communication with the beverage outlet of the whole machine through a pipeline structure, and the prepared coffee beverage can be discharged outward.

[0063] In view of the above, the weight of the coffee powder discharged outward from the outlet end of the grinding module is the powder weight; and the weight of the coffee liquid (extracted beverage) discharged outward from the outlet end of the brewing module through the beverage outlet is the liquid weight. The powder weight and the liquid weight can be measured by an external general-purpose weight sensor or a pre-installed dedicated weight sensor.

[0064] Taking the pre-installed dedicated weight sensor as an example, the powder weight and the liquid weight can be measured by the weight sensor.

[0065] The machine body can further include a powder weight module.

[0066] In an 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 is connected in communication with the outlet end of the grinding module, and the outlet end of the powder weight module is connected in communication with the inlet end of the brewing module. The powder weight module can be fixedly installed in the machine housing or detachably installed in the machine 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 driven to move close to the grinding module by a user manually or by a pre-installed power module automatically:

[0067] When the inlet end of the powder weight module is connected in communication with 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 outward from the outlet end of the grinding module, and perform a weighing function in real time or after a preset grinding time, in which case the powder weight module is in a weighing mode. Of course, the powder weight module can also receive and accommodate the coffee powder discharged outward from the outlet end of the grinding module, but does not perform a weighing function, in which case the powder weight module is in a pre-receiving mode without weighing.

[0068] When the inlet end of the powder weight module is connected in communication with the outlet end of the grinding module, and the outlet end of the powder weight module is connected in communication with the inlet end of the brewing module, the powder weight module is set in an always-open form, so that the powder is free and unobstructed through the powder weight module when the powder is transported from the grinding module to the brewing module. The powder weight module mainly functions as a transition of the powder, and does not perform the function of weighing. At this time, the powder weight module is in a non-weighing transition mode.

[0069] It should be noted that when the powder weight module is applied in the beverage cooking device, the powder weight module is placed as a modular component in the machine shell, and the powder weight module and the machine shell are quickly disassembled. An installation area is formed between the grinding module and the brewing module. When the powder weight module is installed in the machine shell, that is, installed in the installation space, the installation space is filled. But when the powder weight module is disassembled from the machine shell, the installation space is empty: At this time, in an 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 machine shell. Especially when the powder weight module is removed from the machine shell, the position of the original powder weight module in the machine shell can be replaced by moving the brewing module and / or the grinding module, so as to avoid the above-mentioned installation space being empty, so that the brewing module and the grinding module are as close as possible to avoid the powder scattering in the transfer process. Alternatively, in another embodiment, a detachable or integral but deformable communication structure can be provided between the grinding module and / or the brewing module. When the powder weight module is installed in the machine shell, the communication structure is compressed and deformed to avoid forming the above-mentioned installation space; on the contrary, when the powder weight module is disassembled from the machine shell, the communication structure is elongated and deformed to communicate the grinding module and the brewing module, so as to avoid the above-mentioned installation space being empty. The communication structure can be a soft rubber channel, and the specific form is not limited.

[0070] In view of the above, the beverage cooking device further comprises a control device 100. The control device 100 can be built-in in the machine shell, or can be external to the machine shell. The control device 100 can combine the preset in-situ sensor to intelligently identify whether the powder weight module is installed in the machine shell and whether it is installed in place in the machine shell, so that whether the powder weight module is installed and whether it is installed in place can be flexibly selected, so that the beverage cooking device can be applied to different use scenarios and realize different use functions.

[0071] Of course, in an embodiment, the beverage processing device can be adjusted by manual setting whether the beverage processing device is currently in the above-mentioned weighing mode or in the above-mentioned non-weighing mode. When the powder weight module is in the weighing mode, the powder weight module is generally already installed in the machine housing and is installed in place in the machine housing, and the weighing function is enabled. When the powder weight module is in the non-weighing mode, it can be, but is not limited to, that the powder weight module is not installed in the machine housing; the powder weight module has been installed in the machine housing but is not installed in place; the powder weight module has been installed in the machine housing and is installed in place, but the weighing function is not started, and it can currently be in the above-mentioned non-weighing pre-accepting mode, or the non-weighing transition mode, etc.

[0072] It should be noted that when the powder weight module is in the weighing state, the control device 100 first resets the weighing value of the powder weight module before each execution of the powder falling and weighing, so as to reduce the influence of the powder weight deviation caused by the factors of the powder weight module itself as much as possible.

[0073] Specifically, the powder weight module can include a connected receiving container 410 and a weighing device 420, the receiving container 410 includes a container body 411 formed with a receiving channel, and an opening and closing member 412 movably arranged in the receiving channel, the opening and closing member 412 has an open position for opening the receiving channel and a closed position for blocking the receiving channel. The container body 411 is generally cylindrical, the receiving channel formed therein is long and extends along the up-down direction. At this time, the upper end of the receiving channel constitutes its inlet end, which can be connected with the outlet end of the grinding cylinder in the grinding module; the lower end of the receiving channel constitutes its outlet end. The opening and closing member 412 can be movably arranged at the outlet end of the receiving channel to open and close the outlet end of the receiving channel.

[0074] The machine body can further include a liquid weight module.

[0075] In an embodiment, the machine housing generally has a beverage outlet at its front panel, and a receiving table is arranged below the beverage outlet. The beverage outlet can be connected with the outlet end of the brewing module. The receiving table is provided with a water receiving groove for receiving the liquid discharged outward. The receiving table can further have a grid member arranged at the groove opening of the water receiving groove, which can at least be used to support containers such as cups, bottles, bowls, and cans, while not hindering the water receiving function of the water receiving groove. The containers are used to hold the beverages discharged outward by the beverage outlet.

[0076] The liquid weight module generally includes a tray integrated with a weighing device, the tray can be placed on the receiving table, and when the coffee liquid discharged outward by the beverage outlet is received, the weighing device can measure the weight of the received coffee liquid in real time. The liquid weight module can be fixedly installed on the machine body, or can be detachably installed on the machine body.

[0077] In an embodiment, the tray is reversibly movable relative to the front panel between an active state in which the tray is disposed on the receiving platform and an inactive state in which the tray is disposed proximate to and folded against the front panel. In this regard, both the active state and the inactive state can be automatically recognized by the control device 100 and the preset sensor means in the beverage preparation apparatus.

[0078] To implement the weighing function of the liquid, the liquid weighing module has at least a weighing mode and a non-weighing mode. In the active state, the liquid weighing module can selectively enable the weighing mode or the non-weighing mode.

[0079] In addition, in an embodiment, the liquid weighing module further comprises a display assembly electrically connected to the weighing device to display the measurement results of the weighing device. The display assembly can display any suitable information according to actual needs, such as directly and in real time displaying the actual measurement data of the weighing device, displaying associated data obtained by converting the actual measurement data, displaying state information of the weighing function of the weighing device, etc. The display assembly can be disposed on the tray, or the display assembly can be disposed separately from the tray, such as externally on the housing.

[0080] When the liquid weighing module itself forms a container for receiving liquid, if the current liquid weighing module is in the active state, before each liquid weighing measurement is performed, the control device 100 first resets the weighing value of the liquid weighing module to minimize the influence of the liquid weighing module itself on the powder weighing deviation.

[0081] When the liquid weighing module itself does not have a container for receiving liquid, but receives liquid through an externally provided container, if the current liquid weighing module is in the active state, before each liquid weighing measurement is performed, it is first detected whether there is a container placed on the tray of the liquid weighing module, and after the weight of the container is detected, the system resets the weighing value of the liquid weighing module.

[0082] It can be understood that the above-mentioned operation of resetting the weighing value of the liquid weighing module can be performed before the system runs the beverage preparation mode, specifically, for example, before the brewing module starts the extraction operation, and after the weighing value is reset, the brewing module is controlled to start the extraction operation.

[0083] In an embodiment, according to actual needs, the liquid weighing module can further comprise a timer which can be directly electrically connected to the weighing device or indirectly associated with the weighing state of the weighing device, for example, by being electrically connected to the control device 100. The timer is provided with a timing mode and a non-timing mode. When in the timing mode, the timer can record any required time point and duration during the weighing process of the weighing device.

[0084] 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. Generally, 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 weight of the beverage in the container reaches a preset value, it simultaneously cuts off the liquid outlet pipeline, or controls the brewing module to stop extraction (i.e., stops supplying water to the brewing cylinder), or adopts the form of cutting off the liquid flow of the extracted beverage or bypassing the liquid flow of the extracted beverage to achieve the purpose of stopping liquid output.

[0085] As can be seen from the above, the functional mode of the liquid weight module at least includes a weighing mode or a non-weighing mode that can be selectively enabled in the enabled state; and according to actual needs, it can also include a timing mode and a non-timing mode that can be selectively enabled in the enabled state.

[0086] It should be noted that according to actual needs, the machine body can also include other devices. For example, when the beverage preparation device can be used to prepare a flavored beverage, the beverage preparation device can also include a material supply module. The machine shell is provided with a material output pipeline, and the material output pipeline is in communication connection with the material supply module to selectively output the material to be blended. Among them, the flavored beverage is obtained by blending at least two materials to be blended. Among them, the material to be blended can include a beverage (such as coffee liquid) extracted by the brewing module, and can also include a material provided by the material supply module and the material output pipeline.

[0087] Specifically, in an embodiment, the material supply module includes a milk supply module, the material output pipeline corresponds to a milk output pipeline, and the material to be blended corresponds to milk.

[0088] In actual application, the beverage outlet and the material output pipeline are arranged at intervals. At this time, in order to enable the liquid weight module to measure the weight of the beverage (such as coffee liquid) discharged outward by the beverage outlet and the weight of the material (such as milk) discharged outward by the material output pipeline:

[0089] In an embodiment, the material output pipe can be arranged to be movably adjustable in a direction close to and away from the beverage outlet, so that in an enabled state, the material output pipe can be moved above the liquid weight module to discharge material to the liquid weight module. The movement of the material output pipe can be achieved by at least partial deformation of the structure of the material output pipe itself, for example, at least part of the pipe section of the material output pipe is composed of a telescopic deformable pipe body, so that by adjusting the elongation deformation of the material output pipe, the distance between the material output pipe and the liquid weight module can be shortened; on the contrary, by adjusting the shortening deformation of the material output pipe, the distance between the material output pipe and the liquid weight module can be lengthened. Further, when the liquid weight module is arranged directly below the beverage outlet and is staggered with the material output pipe in the transverse direction, at least part of the pipe section of the material output pipe is composed of a laterally bendable pipe body, so as to be able to bend towards the liquid weight module and bend away from the liquid weight module.

[0090] Alternatively, in an embodiment, the liquid weight module can be arranged to be movably adjustable between the beverage outlet and the material output pipe, so that in an enabled state, the liquid weight module can be moved to be respectively below the beverage outlet and below the material output pipe. At this time, the positions of the beverage outlet and the material output pipe relative to the housing are fixed. When the weight of the coffee liquid discharged outwardly by the beverage outlet needs to be measured, the liquid weight module can be adjusted to be directly below the beverage outlet; on the contrary, when the weight of the milk liquid discharged outwardly by the material output pipe needs to be measured, the liquid weight module can be adjusted to be directly below the material output pipe.

[0091] After the beverage preparation device runs in the beverage preparation mode and obtains the beverage, the weight of the beverage can be measured by the liquid weight module. The running of the beverage preparation mode is started in response to a preset instruction. The preset instruction is not limited, and can be, but is not limited to, a debugging instruction when debugging and calibrating parameters, or a working instruction when a user normally uses the device, etc.

[0092] The following will be specifically described by taking the debugging instruction as an example:

[0093] Generally, for the process of extracting a cup of high-quality coffee by the beverage preparation device, there are many factors involved. Among them, the conventional parameters include the proportion between the weight of coffee powder and the weight of extracted coffee liquid, which usually needs to be controlled within a range of about 1:2 (actual situation allows a certain range of weight deviation). Of course, the specific powder-liquid ratio can be adjusted according to different coffee bean varieties, the taste of the beverage to be extracted, and other various factors.

[0094] According to different system configuration requirements and in order to realize the functions of various functional modules, the parameters involved in the device detection include but are not limited to the following:

[0095] Table 1 Parameter information table of grinding module

[0096]

[0097] The parameter value of the cutter disc grinding gap directly determines the particle size of the ground coffee powder, thereby causing the extraction time of the coffee powder in the brewing module to change due to the particle size of the coffee powder in the same extraction environment and conditions. In principle, the larger the grinding gap, the larger the particle size of the ground powder, and the gap between the particles under the same pressure in the brewing module is relatively large, and the water flow during extraction passes quickly; otherwise, the opposite is true.

[0098] In actual application, preferably, the entire adjustment amount of the cutter disc grinding gap can be divided into multiple gear levels, for example, from -50 to 50 gears, a total of 100 gears, each gear with a difference value of 0.01 mm (the number of gear levels can be selected and set, and does not necessarily have to be a constant gear level), or can be set to display the actual gap value in real time.

[0099] The parameter information of the powder weight module includes: the preset powder weight after grinding through the grinding module can be set and obtained, that is, the powder weight used for extraction in the brewing module. The parameter range of the preset powder weight setting can be different from 8g to 36g according to the needs of different beverages. After the powder weight module is set and enabled in the beverage cooking equipment, the powder weight of the ground powder does not need to be measured by the grinding time of the cutter disc, so after the powder weight module is set and enabled in the beverage cooking equipment, the value of the grinding time of the cutter disc does not need to be detected and obtained, but under certain functional requirements, the powder weight module can be set and enabled and the grinding time of the cutter disc can be detected and obtained at the same time to achieve other additional functions. Please refer to the description in other paragraphs of the present application.

[0100] Table 2 Parameter information table of brewing module

[0101]

[0102] Table 3 Parameter information table of liquid weight module

[0103]

[0104] When setting the parameters of the knife disc of the grinding module, the value of the knife disc grinding gap needs to be adjusted first. The value of the knife disc grinding gap determines the particle size of the coffee powder after grinding by the grinding module. An excessively large particle size will cause the powder cake to be insufficiently extruded, the extraction flow rate to be excessively fast, and thus insufficient extraction. An excessively small particle size will cause the powder cake to be excessively extruded, the extraction flow to be excessively slow, and thus excessive extraction. To obtain a suitable range of particle sizes, the value of the knife disc grinding gap needs to be adjusted to a reasonable range. However, with long-time high-speed grinding, the knife disc will gradually wear out, so that the value of the grinding gap between the knife discs changes. 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 knife disc grinding gap according to the obtained relevant parameter value, so as to keep the quality of the prepared beverage stable.

[0105] In order to stabilize the quality of coffee extraction, according to the gold cup principle of coffee extraction, a perfect-flavor coffee beverage needs to have 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 enable the beverage preparation equipment to have more accurate control over the powder weight during equipment operation. In other embodiments, the grinding time of the grinding module at each start and stop is measured to obtain the information of the amount / weight of the ground powder.

[0106] Making espresso coffee needs to go through three stages of pre-soaking program, flavor substance extraction, and end of extraction. The pre-soaking program is mainly used to remove carbon dioxide and improve extraction efficiency. Before extracting the coffee powder, pre-soaking the extruded powder cake under 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, a certain amount of hot water is injected into the coffee powder cake under a certain pressure, so that the powder cake absorbs water and releases more aroma and flavor. Further, pre-soaking can make the powder cake fully wet, and the water flow during extraction is better distributed. Of course, the pre-soaking pressure and the pre-soaking time can be determined according to different coffee bean varieties or powder amounts or powder cake thicknesses, etc. Therefore, the pre-soaking pressure can also be set to 0, i.e. pre-soaking with no pressure injection. The pre-soaking time can also be set to 0, i.e. no pre-soaking program is performed.

[0107] Generally, the pre-soaking pressure is not set to be greater than the extraction pressure. Pre-soaking aims to wet the powder cake, and it is not desirable for the water flow during pre-soaking to flow out of the powder.

[0108] For example, when the powder weight module is pre-set in the beverage preparation device as described above, the powder cake parameter can be represented by the powder weight measured by the powder weight module or by the powder cake thickness. The powder cake refers to the block structure formed by the ground powder transferred into the brewing cylinder of the brewing module after the pressure module (e.g., the upper piston and the lower piston are pressed against each other) in the brewing cylinder. The powder cake thickness can be detected by the movement stroke or distance of the upper piston and / or the lower piston, pre-set position sensor sensing, etc.

[0109] In the beverage preparation device provided in the present application, the upper piston and the lower piston can be used to press the powder at a preset pressure to form a powder cake of a certain thickness after the coffee powder is transferred to the brewing module, and an extraction process is performed. The extraction process includes a pre-soaking program and an extraction program set by the system or selected by the user. A time interval can be selected between the pre-soaking program and the extraction program to give the pre-soaking program a certain soaking time. The total water amount used by the pre-soaking program and the extraction program together is the total water amount L set in the system. Even if the user turns off the pre-soaking function, the total water amount for extraction is still L. It can be understood that the total water absorption of the coffee powder cake after being pressed into shape will not change much, whether it is pre-soaked or not. When the beverage preparation device needs to obtain a fixed amount of extraction liquid, the total water amount L needed is a fixed value range, and the value of the total water amount L for the extraction process can be accurately measured by a flow meter, a flow valve, a timer, etc. Further, in addition to the pre-soaking program and the extraction program, other programs can also be configured in the extraction process, which are not limited herein, but the total water amount L for the extraction process is a fixed set value.

[0110] In view of the above, when the liquid weight module is in an enabled state, the liquid weight module first performs the zeroing operation of the weighing value when it measures that the container is placed on the tray. In a specific application of the beverage preparation device provided in the present application, after the selected beverage is set, the grinding module can be started to grind the coffee beans after the liquid weight module measures that the container is placed in position and the weighing value is zeroed. Alternatively, the brewing module can be started to perform the brewing program after the liquid weight module measures that the container is placed in position and the weighing value is zeroed after the grinding module is first started to grind the coffee beans. It can be understood that when the liquid weight module does not detect that the container (with a change in the weighing weight) is placed on the tray, the grinding module and / or the brewing module will not be started. Of course, the above-mentioned program related to the weighing of the liquid weight module can also be selected to be turned off in the program setting of the beverage preparation device.

[0111] The total water amount L in the extraction process is to ensure the stable liquid amount of the beverage after extraction, and can match other parameters to realize the detection and other functions of the beverage cooking device. In the embodiments of the present application, the liquid weight module can accurately detect the accurate liquid weight of the beverage in this extraction until the liquid weight detected by the liquid weight module no longer increases after the extraction process is completed.

[0112] Further, the liquid weight module can be used to measure the total water amount L consumed when the liquid weight module detects no continuous increase in liquid weight at the moment when the liquid outflow stops under the condition of a fixed total water amount L, to obtain the total liquid weight, and to compare the data with the preset total water amount L to determine whether the weight of the powder cake meets the requirements. If the actual water amount L' is greater than the preset total water amount L, it is a warning that the powder amount for extraction is too large. If the actual water amount L' is less than the preset total water amount L, it is a warning that the powder amount for extraction is too small.

[0113] The parameter values obtained by the above grinding module, powder weight module and liquid weight module can have a certain deviation range. When the values fall within the deviation range, it is also recognized as being in a normal working state. The related parameter values in the present application are by default to include a reasonable deviation range and a reasonable deviation set by the system. The specific deviation range is not limited in the present application and can be adjusted or set in the beverage cooking device according to different needs. The specific values of the parameter values and the deviation range involved in the present application are illustrative values and are not limited as values. The adjustment of the illustrative values is easy to be thought by the researchers in the field and cannot be used as the key points to avoid the present application.

[0114] In view of the above, when running in a normal state, for example, in response to a working instruction, the powder weight module is generally used in cooperation with the powder supply module. For example, the container body 411 in the container 410 receives the powder prepared by the grinding module, and the weighing device 420 weighs the powder to obtain the corresponding powder weight value.

[0115] However, when the use meets certain conditions, for example, the working time, the working frequency, the total weight, etc. reach a certain threshold; or for example, when the installation environment, the built-in mechanical structure or the control program of the powder weight module is changed, it may be necessary to calibrate the weighing value of the powder weight module.

[0116] To this end, the beverage processing apparatus provided in the present application further comprises a counterweight part 500. The counterweight part 500 is movably arranged relative to the receiving container 410 to have a weighing position connected with the receiving container 410 and a separation position disconnected from the receiving container 410. Wherein, the counterweight part 500 is a structure with a fixed weight, for example, a metal block such as a weight.

[0117] The counterweight part 500 is movable relative to the receiving container 410, and the movement mode of the counterweight part 500 is not limited in the present embodiment. The movement mode includes a movement form, for example, the counterweight part 500 can be movably switched between the weighing position and the separation position in a translational, rotational or other movement form. The movement mode also includes a movement trajectory, for example, the counterweight part 500 can be movably switched between the weighing position and the separation position in a linear movement or an arc movement. The movement mode also includes a driving mode, for example, the counterweight part 500 can be movably switched between the weighing position and the separation position by manual operation of a user or by driving of a driving mechanism. The driving mechanism can be in any suitable form, for example, including a motor, a linear cylinder, etc. driving device, and can also include a transmission assembly such as a gear set, a gear and rack mechanism, a screw nut mechanism, a rocker mechanism, etc. The driving mechanism can be separately provided for driving the counterweight part 500 to move, or can be borrowed from other mechanisms fixed in the beverage processing apparatus.

[0118] It should be noted that the movement mode of the counterweight part 500 can be fixed, that is, after assembly, the counterweight part 500 is driven by a basically fixed driving mode, along a basically fixed movement trajectory, and performs a basically fixed movement. At this time, the counterweight part 500 is more suitable for being driven by the driving mechanism.

[0119] Of course, the movement mode of the counterweight part 500 can also be arbitrarily variable, that is, after assembly, the counterweight part 500 is driven by an arbitrarily variable driving mode, along an arbitrarily variable movement trajectory, and performs an arbitrarily variable movement. At this time, the counterweight part 500 is more suitable for being driven by manual operation of the user.

[0120] In addition, in an embodiment, the beverage processing device further comprises a housing, the powder weight module is accommodated in the housing, and the counterweight 500 is selectively installed in or outside the housing. The housing is openable. Specifically, for example, the housing is provided with an openable cover or door, and the inner cavity of the housing is exposed at least for the area where the powder weight module and the counterweight 500 are located. The preset driving mechanism or the driving external force manually applied by the user is connected with the counterweight 500 through the opening of the housing, and then drives the counterweight 500 to switch between the weighing position and the separation position.

[0121] Alternatively, in an embodiment, the beverage processing device further comprises a housing and a driving mechanism, the counterweight 500 and the powder weight module are both accommodated in the housing, and the driving mechanism drives the counterweight 500 to switch between the weighing position and the separation position. Moreover, the powder weight module and the driving mechanism are both electrically connected with the control device 100, so that the start and stop of the driving mechanism, the start, weighing and stop of the powder weight module, etc. are all automatically controlled and realized by the driving device. The driving device can also automatically receive the weighing data of the powder weight module.

[0122] Wherein, no matter whether it is installed outside or inside the housing, the connection mode of the counterweight 500 and the structure to be assembled to which the counterweight 500 is assembled is not limited. The structure to be assembled can be defined by any component in the beverage processing device, such as the housing, the grinding module, the brewing module, etc. That is, when in the separation position, the counterweight 500 is in a non-working state. Taking the housing as an example, a placement platform can be protruded or a receiving groove can be recessed on any outer wall of the housing for placing the counterweight 500. Alternatively, at least one of the outer wall of the housing and the counterweight 500 is provided with a magnetic attraction structure, and the other is provided with a magnetic cooperation structure, so that the housing and the counterweight 500 can be magnetically fixed through the magnetic attraction structure and the magnetic cooperation structure.

[0123] Specifically, when the working instruction is triggered, the outlet end of the powder supply module is connected in communication with the receiving container 410 to access the powder into the receiving container 410. The counterweight 500 is in the separation position, and the counterweight 500 is arranged away from the powder flow path between the powder supply module and the receiving container 410. That is, the counterweight 500 does not block the position between the outlet end of the powder supply module and the inlet end of the receiving container 410, so as to avoid the counterweight 500 interfering with the process of the powder supply module transferring the powder to the receiving container 410.

[0124] When moved to the weighing position, the connection mode of the counterweight 500 and the receiving container 410 in the powder weight module is also not limited, so that only the counterweight 500 or the counterweight 500 and the receiving container 410 can apply force to the weighing device 420.

[0125] In an embodiment, the receiving container 410 is formed with a receiving cavity; and the counterweight 500 is received in the receiving cavity when in the weighing position. That is, when the outer diameter of the counterweight 500 is smaller than the inner diameter of the receiving cavity, the counterweight 500 can be directly put into the receiving cavity, like receiving powder, for the weighing device 420 to weigh the whole of the receiving container 410 and the counterweight 500, and obtain the weighing value of the counterweight 500.

[0126] Or in an embodiment, the counterweight 500 is placed on the upper end of the receiving container 410 when in the weighing position. That is, if the counterweight 500 is closer to the upper end of the receiving container 410, and the upper end of the receiving container 410 leaves enough space for the counterweight 500 to be stably placed, the counterweight 500 can be optionally directly placed on the upper end of the receiving container 410.

[0127] Or in an embodiment, the receiving container 410 is suspended on one side of the weighing device 420; and the counterweight 500 is hung on the lower end of the receiving container 410 when in the weighing position. That is, if the counterweight 500 is closer to the lower end of the receiving container 410, and the lower end of the receiving container 410 leaves enough space for the counterweight 500 to be stably connected, the counterweight 500 can be optionally directly hung on the lower end of the receiving container 410.

[0128] When in the weighing position, the connection between the counterweight 500 and the receiving container 410 can be a contact type or a non-contact type. And the connection between the counterweight 500 and the receiving container 410 can be, but is not limited to, magnetic connection, insertion connection, adhesive connection, etc.

[0129] In view of the above, when the measurement instruction is triggered, the counterweight is moved to the weighing position, and the weighing value is obtained by the weighing device 420, so that the control device 100 controls the calibration of the powder weight module according to the weighing value and the calibration value of the counterweight 500.

[0130] In the technical scheme provided in the application, when the working instruction is triggered, the powder weight module is normally used, the receiving container 410 can receive the powder, the weighing device 420 weighs the receiving container 410 and the powder received thereby as a whole to obtain the weight value of the powder, and high-quality drinks can be prepared; when the measurement instruction is triggered, the counterweight part 500 is moved to the weighing position, the receiving container 410 does not receive other materials, and the weighing device 420 only weighs the weight of the counterweight part 500 to obtain the weighing value of the weight. Since the counterweight part 500 has a relatively accurate and known weight calibration value, when the deviation between the weighing value and the calibration value does not exceed the deviation threshold value, it is basically determined that the current weighing accuracy of the powder weight module is normal, and calibration is not required. Conversely, when the deviation between the weighing value and the calibration value exceeds the deviation threshold value, it is basically determined that the current weighing accuracy of the powder weight module is abnormal, and calibration is required. The application can more intuitively know whether the weighing accuracy of the powder weight module is abnormal, and can calibrate the powder weight module in time when an abnormality is found, and has the characteristics of simple structure and efficient operation.

[0131] It can be understood that when the beverage preparation device is provided with the control device 100 as described above, the control device 100 can receive and analyze the above-mentioned data and correspondingly issue a control instruction. In other embodiments, when the beverage preparation device does not have a special control device 100, the above-mentioned functions can be realized by an external control device 100.

[0132] Since the calibration value is known and fixed, when the powder weight module weighs the counterweight part 500 and obtains the weighing value, the control device 100 can compare the calibration value and the weighing value to obtain the deviation therebetween.

[0133] If the counterweight part 500 is provided with one or more counterweight parts, but the calibration values of the counterweight parts 500 are the same, the counterweight part 500 can be weighed multiple times, and finally multiple weighing values corresponding to the same calibration value can be obtained, multiple deviations can be correspondingly obtained, and after the deviations are averaged or screened, the required deviation can be compared and analyzed with the preset deviation threshold value.

[0134] If the counterweight part 500 is provided with several counterweight parts, and the calibration values of the counterweight parts 500 are different, the counterweight part 500 can also be weighed multiple times, and finally multiple weighing values corresponding to different calibration values can be obtained, multiple deviations can be correspondingly obtained, and after the deviations are averaged or screened, the required deviation can be compared and analyzed with the preset deviation threshold value.

[0135] The beverage preparation device further comprises an input module. The input module can be used only for inputting parameters or triggering instructions and does not have a display function. Alternatively, the input module can have both triggering and display functions, for example, forming a display and control module.

[0136] Specifically, the input module is taken as an example of the display and control module, and the display and control module is electrically connected with the control device 100. At least the display screen of the display and control module is exposed outside the shell to be manually operated by the user. The control button part of the display and control module can realize the input function as described above. The display part of the display and control module can display preset numbers, characters, patterns, etc. to assist the user to understand the state of the parameter calibration, parameter debugging, normal use, etc. of the current beverage preparation equipment.

[0137] The display and control module can use the touch liquid crystal display screen of the beverage preparation equipment of the present application as the input module of the preset parameters, and in addition, can be input by the connected external devices, such as mobile devices, such as mobile phones, tablet computers, notebook computers, PDAs, etc. to constitute the input module. In the preferred embodiment, the beverage preparation equipment is provided with a touchable liquid crystal display screen, and the above-mentioned parameters can be selectively presented on the display screen, and the parameter input can be realized by touch.

[0138] Specifically, please refer to FIGS. 23 to 25:

[0139] In an embodiment, the input module includes a first trigger part electrically connected with the control device 100, which forms a measurement instruction when triggered and sends it to the control device 100. The first trigger part, such as P1 area in FIG. 25, can be realized by a button. When the first trigger part is triggered by the user, the input module sends a measurement start instruction to the control device 100, which controls the driving mechanism to drive the counterweight part 500 to move to the weighing position, and controls the weighing device 420 in the powder weight module to start the weighing mode.

[0140] Wherein, when the first trigger part is triggered to form a measurement instruction, the counterweight part 500 is repeatedly switched between the weighing position and the separation position for a preset number N to obtain N weighing values by the weighing device 420. That is, if the same or multiple counterweight parts 500 need to be measured repeatedly, the driving mechanism needs to be controlled by the control device 100, or the counterweight part 500 needs to be manually operated by the user to move between the weighing position and the separation position, and the weighing values obtained by the measurement are recorded respectively.

[0141] Then, in an embodiment, the input module includes an input unit electrically connected to the control device 100; when the powder weight module weighs the counterweight unit 500, the input unit is used by the user to input the measured value and / or the calibration value, and sends to the control device 100. As shown in FIG. 25, the input module is pre-provided with a P4 area for the user to manually input the calibration value of the same counterweight unit 500 or different counterweight units 500 at each measurement; a P5 area for the user to manually input the measured value obtained at each measurement. Optionally, a P6 area can also be provided at the corresponding position of each measurement to display the state of each measurement process, which can be, for example, measurement completed, measurement in progress, no measurement; calibration completed, calibration in progress, or no calibration, etc., for the user to intuitively view.

[0142] In addition, in an embodiment, the input module includes a second trigger unit electrically connected to the control device 100; when triggered, the second trigger unit forms a calibration instruction and sends to the control device 100. As shown in FIG. 25, the input module is pre-provided with a P3 area for the user to manually trigger the calibration instruction. However, it can be understood that this does not constitute a limitation on the form of triggering the calibration instruction, and optionally, when it is determined that the deviation of the measured value and the calibration value exceeds the deviation threshold, the control device 100 can directly trigger the calibration instruction automatically.

[0143] Of course, in an embodiment, the input module includes a third trigger unit electrically connected to the control device 100; when triggered, the third trigger unit forms a measurement cancellation instruction and sends to the control device 100. As shown in FIG. 25, the input module is pre-provided with a P2 area for the user to manually trigger the measurement cancellation instruction. When the third trigger unit is triggered by the user, the input module sends the measurement cancellation instruction to the control device 100, which controls, for example, the driving mechanism described above to drive the counterweight unit 500 to the separation position, and controls the opening and closing member 412 in the powder weight module to open the container body 411, so that the powder received in the container body 411 is emptied.

[0144] In addition, based on any of the above embodiments, the beverage preparation apparatus can be built-in or externally connected with the 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, etc.

[0145] The control device 100 includes a memory 150, a processor 110, and a control program of the beverage preparation apparatus stored on the memory 150 and executable on the processor 110.

[0146] Referring to FIGS. 10-14, FIGS. 10-14 are structural schematic diagrams of the control device 100 of the hardware running environment involved in the embodiment scheme of the present application.

[0147] As shown in FIGS. 10-14, the control device 100 can include a processor 110, such as a central processing unit (CPU) 110, a communication bus 120, a user interface 130, a network interface 140, and a memory 150. The communication bus 120 is configured to enable communication between the components. The user interface 130 can include a display, a keyboard, and optionally a standard wired interface, a wireless interface. The network interface 140 can optionally include a standard wired interface, a wireless interface (e.g., a WIreless-FIdelity (WI-FI) interface). The memory 150 can be a high-speed random access memory (RAM) 150 or a stable non-volatile memory 150 (NVM), such as a disk storage device. The memory 150 can optionally be a storage device independent of the processor 110.

[0148] Based on different functional configurations of the beverage cooking apparatus, corresponding sensors and functional modules can be provided to measure or monitor the above-mentioned parameter values, and transmit the parameter values to the processor 110 in real time or according to a predetermined setting, so as to realize various functional combinations between different parameter modules.

[0149] Those skilled in the art can understand that the structure shown in FIGS. 10-14 does not constitute a limitation on the control device 100, and can include more or fewer components than those shown, or combine certain components, or different component arrangements.

[0150] As shown in FIGS. 10-14, the memory 150 as a storage medium can include an operating system, a network communication module, a user interface 130 module, and a control program of the beverage cooking apparatus.

[0151] In the control device 100 shown in FIGS. 10-14, the network interface 140 is mainly used for data communication with a network server; the user interface 130 is mainly used for data interaction with a user; the processor 110 and the memory 150 in the control device 100 can be arranged in the beverage cooking apparatus, and the control device 100 calls the control program of the beverage cooking apparatus stored in the memory 150 by the processor 110, and executes the control method of the beverage cooking apparatus provided in the embodiments.

[0152] It should be noted that the control program and method of the beverage preparation device can be embodied as the debugging program and method of the beverage preparation device in the first and second application examples as shown in FIG. 10, the calibration program and method of the beverage preparation device in the third application example as shown in FIG. 11, the liquid weight measurement program and method of the beverage preparation device in the fourth application example as shown in FIG. 12, the grinding gap adjustment program and method of the beverage preparation device in the fifth application example as shown in FIG. 13, the powder weight calibration program and method of the beverage preparation device in the sixth application example as shown in FIG. 14, and the beverage preparation parameter adjustment program and method in the seventh application example.

[0153] It should be noted that the above structure does not constitute a limitation on the specific form of the beverage preparation device. In actual applications, the beverage preparation device can be an automatic beverage preparation device comprising the above-mentioned modules, such as a coffee machine, a soy milk machine, etc., which has grinding, brewing, and weighing functions, etc.

[0154] For example, the beverage preparation device comprises a grinding module and a brewing module. In one application, the grinding module and the brewing module can be assembled in the same housing, i.e., integrated into one product, such as a fully automatic coffee machine.

[0155] Alternatively, in one application, the grinding module and the brewing module can be assembled in two independent and different housings, constituting two independent products. For example, the beverage preparation device can comprise a bean grinder 200 and a brewing machine 300 (which can be embodied as a semi-automatic coffee machine) that are independently arranged and used in combination. The bean grinder 200 mainly operates the grinding function and the powder weighing function, and the brewing machine mainly operates the brewing function, the liquid weight measurement function, and the extraction time calculation function. At this time, when the powder weight module and the liquid weight module are provided, they can be selectively arranged in the bean grinder 200, arranged in the brewing machine 300, or arranged independently of the bean grinder and the brewing machine according to actual needs.

[0156] Please refer to FIGS. 21 and 22. A preferred embodiment of the present application is to arrange the beverage preparation device in the form of a bean grinder 200 and a brewing machine 300 arranged independently.

[0157] In this embodiment, the bean grinder 200 and the brewing machine 300 can be communicatively connected in a wired or wireless manner. The control device 100 can be selectively arranged in the bean grinder 200, arranged in the brewing machine 300, or arranged independently of the bean grinder and the brewing machine according to actual needs.

[0158] Further, the beverage preparation device can employ a third-party external mobile device. The mobile device can be, but is not limited to, a mobile phone M1, a notebook computer M2, a tablet computer M3, a PDA, etc. The mobile device can be connected to the control device 100 in a wired or wireless manner, which is equivalent to being connected to the coffee grinder 200 and the coffee maker 300 in a wired or wireless manner.

[0159] The mobile device can constitute the input module or the display and control module in the above or the following embodiments. At this time, the values of all preset parameters of the coffee grinder 200 and the coffee maker 300 are input by the mobile device and transmitted to the control device 100 for storage, calling, and execution. Alternatively, an input module for inputting preset parameters can be provided in at least one of the coffee grinder 200 and the coffee maker 300. The input module is different from the mobile device described above. The input module can be provided in two, and is provided in the coffee grinder 200 and the coffee maker 300, respectively, to input and manage the parameters of the coffee grinder 200 and the coffee maker 300, respectively. The values of all preset parameters of the coffee grinder 200 and the coffee maker 300 are input by the input module to the control device 100 for storage, calling, and execution. As described above, the input module can be a key module, a display and control module, a plug-in chip module, etc.

[0160] In view of the above, the coffee grinder 200 and the coffee maker 300 can be independently provided or installed in the same housing. Generally, a powder bowl is provided between the coffee grinder 200 and the coffee maker 300, which is used to hold the powder obtained by the grinding module and to provide space for the brewing and extraction operation (equivalent to the brewing cylinder described above). The powder bowl can be reciprocally movable between the coffee grinder 200 and the coffee maker 300, and the driving force during the movement can be manually controlled by the user or automatically controlled by a preset electric control power module. After the powder weighed by the powder weighing assembly in the coffee grinder 200 is transferred to the powder bowl, the powder bowl is transferred to the coffee maker 300 for extraction. However, the powder in the powder bowl needs to be compressed before the powder bowl is transferred to the coffee maker 300 for extraction. At this time, the powder compression module described above needs to be provided. In the embodiments of the present application, the powder compression module can be manually compressed or a third-party powder compression mechanism can be used. Preferably, the powder compression module is provided in the coffee grinder 200 or the coffee maker 300. After the powder weighed by the powder weighing assembly in the coffee grinder 200 is transferred to the powder bowl, the powder compression module is used to compress the powder in the powder bowl before the powder is transferred to the coffee maker 300 for extraction. Alternatively, the powder compression module can be provided on the coffee maker 300. After the powder bowl holding the powder is transferred to the coffee maker 300, the powder is compressed before the brewing and extraction program is executed. The pressure of the powder compression module for compressing the powder in the powder bowl can be adjusted as a preset parameter.

[0161] In combination with the above description of the bean bin, it can be understood that one or several bean bins can be provided in the coffee grinder 200. When several bean bins are provided, the bean bins can store the same or at least partially different coffee beans for the user. Each bean bin can be bound to multiple different types of beverages, i.e., the multiple types of beverages are all made of the beans in one bean bin. Moreover, the bean bin can be one-to-one correspondingly adapted to be provided with the grinding module and / or the brewing module; or at least two bean bins share one grinding module and / or one brewing module.

[0162] Based on any of the above embodiments, one brewing machine 300 can be matched for use with multiple coffee grinders 200. Alternatively, one brewing machine 300 can be matched for use with multiple bean bins in one coffee grinder 200.

[0163] The present application provides a control method of a beverage cooking apparatus. The beverage cooking apparatus can be any of the beverage cooking apparatuses described above; or can be other beverage cooking apparatuses.

[0164] The parameter values obtained by the grinding module, the powder weight module, and the liquid weight module can be stored in the memory 150 of the control device 100 in association, or can be independently stored in the memory 150 of the control device 100. Of course, the values can also be entered by the user on site or pre-entered based on the above-mentioned method.

[0165] The above-mentioned parameters can be preset based on the calibration of the beverage cooking apparatus before use, or can be real-time calibrated during use of the beverage cooking apparatus. Once the preset parameter values are determined and the closed loop of the multiple parameter values is achieved, any change or modification of any parameter will break the closed loop formed by the multiple parameter values, and the calibration needs to be reset.

[0166] Based on one or several of the above embodiments of the beverage cooking apparatus, the present application further provides the following multiple application examples of the control method of the beverage cooking apparatus.

[0167] First application example:

[0168] Referring to FIG. 1, in the present design, the control method of the beverage cooking apparatus specifically represents a debugging method of the beverage cooking apparatus, and the debugging method of the beverage cooking apparatus comprises:

[0169] Step S100: obtaining a preset powder weight, a preset liquid weight, and a preset extraction time;

[0170] In the embodiment, the obtaining manner of the preset powder weight, the preset liquid weight, and the preset extraction duration is not limited. The three can be stored in the memory 150 of the control device 100 in association, or can be independently stored in the memory 150 of the control device 100. When needed, the corresponding data can be directly called from the memory 150 by the processor 110.

[0171] Alternatively, the preset powder weight, the preset liquid weight, and the preset extraction duration can also be obtained by the user to input on site or in advance. At this time, the user can 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. The ways to remind the user are various, which can be but are not limited to the light signal of the warning light, the prompt sound of the buzzer, the message push received by the mobile device in communication connection with the control device 100, etc.

[0172] The preset powder weight, the preset liquid weight, and the preset extraction duration are generally associated one by one according to the user's needs. For example, the three can be associated by the same weight of coffee beans. The preset powder weight and the actual powder weight described below can be determined by the weight of the powder weight received by the powder weight module, or the weight of the coffee powder discharged from the outlet end of the grinding module after the coffee beans of the preset weight are ground by the grinding module. The preset liquid weight and the actual liquid weight described below can be determined by the weight of the liquid received by the liquid weight module, or the weight of the coffee liquid finally discharged from the beverage outlet after the coffee beans of the preset weight are ground and the extraction operation of the preset total water amount L. The preset extraction duration and the actual extraction duration described below generally refer to the duration consumed in the extraction process, that is, the duration consumed in the entire process of discharging the coffee liquid from the beverage outlet.

[0173] In the embodiment, the preset powder weight, the preset liquid weight, the preset liquid discharge duration, and other adjustable parameters are all preset values; all parameter values thereof are within the preset values and the acceptable deviation range, and at this time, the value change of the preset extraction duration is the key parameter for determining the quality of the beverage extraction.

[0174] It should be noted that the acquisition time of the preset powder weight, the preset liquid weight, and the preset extraction duration is not limited, which can be obtained simultaneously before the execution of the following step S200 and the like, or can be obtained respectively before the execution of the corresponding steps.

[0175] In addition to the way of directly inputting specific values by the user, in an embodiment, the preset extraction duration can also be obtained by the following way at any time before starting the control program of the beverage cooking device.

[0176] In an application, the following steps can be performed:

[0177] Step S111: Obtain the preset powder weight and the preset liquid weight;

[0178] Step S121: Run the beverage preparation mode, and obtain the current extraction duration when the actual powder weight reaches the preset powder weight and the actual liquid weight reaches the preset liquid weight;

[0179] Step S131: When the quality state of the prepared beverage does not meet the quality requirement, adjust the current corresponding extraction duration, and repeatedly run the beverage preparation mode until the quality state meets the quality requirement, and the current corresponding extraction duration is taken as the preset extraction duration.

[0180] In the embodiment, the preset powder weight and the preset liquid weight can be obtained by the user based on the input module. Then the beverage preparation device is run based on the data, and the beverage is prepared. For the prepared beverage, the taste, quality and other quality states of the beverage can be confirmed by the user tasting or related sensor measurement, flavor data matching and the like. When the quality state meets the preset quality requirement, it indicates that the current beverage preparation quality meets the quality requirement, and the extraction duration corresponding to the current beverage can be taken as the preset extraction duration. However, when the quality state of the beverage cannot meet the preset quality requirement, it indicates that the current beverage preparation is poor, and the extraction duration can be directly or indirectly adjusted, and the beverage preparation mode is run again based on the same preset powder weight and preset liquid weight. The beverage preparation mode is repeatedly run for several times until the quality state of the beverage obtained after running the beverage preparation mode meets the quality requirement, and the extraction duration corresponding to this time is determined as the preset extraction duration and is stored. At this time, the preset extraction duration is the extraction duration obtained in step S100 of the embodiment.

[0181] It should be noted that, when the quality state of the beverage obtained each time does not meet the preset quality requirement, and the extraction duration needs to be directly or indirectly adjusted, one of the adjustment methods is, for example, increasing or decreasing the extraction duration according to the experience of the user or randomly. Another adjustment method is, for example, obtaining the extraction time difference of the extraction duration of the adjacent two times, and adjusting the blade grinding gap according to the extraction time difference. The specific adjustment method of the blade grinding gap according to the extraction time difference will be mentioned below, and will not be repeated here.

[0182] Or in another application, the following steps can be performed:

[0183] Step S112: Obtain the preset powder weight, the preset liquid weight and the preset grinding gap of the blade obtained by the user based on the input module;

[0184] Step S122: running the beverage preparation mode, stopping liquid output 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;

[0185] Step S132: when the quality state of the prepared beverage does not meet the quality requirement, adjusting the blade disc grinding gap according to the preset grinding gap, and repeatedly running the beverage preparation until the quality state meets the quality requirement, taking the current corresponding grinding gap as the reference grinding gap, and taking the current corresponding extraction time as the preset extraction time.

[0186] In the embodiment, the preset powder weight, the preset liquid weight, and the preset grinding gap of the blade disc can be obtained by the user based on the input module described above. Then the beverage preparation device is run and a beverage is prepared. For the prepared beverage, the taste, quality, and other quality states of the beverage can be confirmed by the user tasting or related sensor measurement, flavor data matching, etc. When the quality state meets the preset quality requirement, it indicates that the current preset grinding gap of the blade disc meets the requirement and can be used as the reference grinding gap in the subsequent debugging process. The extraction time corresponding to the current beverage can be used as the preset extraction time. However, when the quality state of the beverage does not meet the preset quality requirement, the current blade disc grinding gap needs to be adjusted, and after adjusting the blade disc grinding gap each time, the beverage preparation mode is repeatedly run once to prepare a new beverage, and the quality state of the beverage is repeatedly confirmed until the quality state of the beverage meets the preset quality requirement.

[0187] It can be understood that when the preset extraction time that meets the quality requirement is obtained as described above, the processing mode of the extraction time is not limited, for example, it can be stored after being confirmed by the user, or it can be stored after being manually input by the user, or the control device 100 automatically updates and replaces the original reference value with the data as a new reference value after storage.

[0188] Step S200: running the beverage preparation mode, stopping liquid output 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;

[0189] In the embodiment, the beverage preparation mode is associated with the triggering of the debugging instruction of the beverage preparation device. The triggering manner of the debugging instruction is not limited, for example, the triggering can be based on a preset button on the control module, a preset program on a mobile terminal in communication connection with the control device 100, a preset voice or a preset action. According to actual needs, the debugging instruction can be subdivided into different debugging instructions corresponding to different debugging objects. In the embodiment, the debugging instruction is mainly used to debug the grinding gap between the two knife plates in the grinding module, so as to adjust the fineness of the coffee powder ground by the grinding module, and ensure the quality of each cup of beverage.

[0190] The beverage preparation mode is a complete and regular process of the beverage preparation device, including grinding, powder taking, powder pressing, and extraction, so that the final debugging result can be directly saved and adapted to the regular beverage preparation mode.

[0191] It can be understood that the actual powder weight in step S200 can be measured by the powder weight module described above, which is 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 liquid output 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", the following steps are further included:

[0192] Step S230: control the grinding module to start grinding and transfer the powder to the powder weight module, and control the grinding module to stop working when the weight of the powder received by the powder weight module reaches the preset powder weight.

[0193] In the embodiment, the control device 100 first controls the grinding module to start running, and starts the powder weight module in the weighing mode at the same time, in advance or after a certain time delay. In this way, when the grinding module grinds the coffee beans into powder and discharges them through the outlet end, the powder weight module can simultaneously receive and weigh the received powder, so that when the weight of the powder received by the powder weight module reaches the preset powder weight, the communication between the grinding module and the powder weight module is immediately cut off, and / or the grinding module is immediately controlled to stop working, avoiding the powder weight module continuously receiving materials, resulting in overloading of the coffee powder.

[0194] Specifically, before executing the step of "controlling the grinding module to start grinding and transferring the powder to the powder weight module" in step S230, the following steps can be further included:

[0195] Step S231: detecting whether the powder weight module is currently installed between the outlet end of the grinding module and the inlet end of the brewing module;

[0196] Step S232: detecting whether the powder weight module is enabled with the weighing mode, when the powder weight module is currently installed between the outlet end of the grinding module and the inlet end of the brewing module; and

[0197] Step S233: when it is confirmed that the powder weight module is enabled with the weighing mode, re-executing the step of "controlling the grinding module to start grinding and to transfer the ground coffee powder to the powder weight module".

[0198] In the present embodiment, the steps S231 to S233 need to be executed and completed before the powder starts to be discharged out of the outlet end of the grinding module, i.e. the grinding module has delivered the ground coffee powder to the powder weight module.

[0199] Since the powder weight module is detachably installed, 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 removed from between the outlet end of the grinding module and the inlet end of the brewing module. In step S231, first of all, it can be automatically detected and confirmed whether the powder weight module is installed in the machine housing and installed in place in the machine housing based on a preset sensor. If the powder weight module has been installed in the machine housing but not installed in place in the machine housing, i.e. the installation direction or the like of the powder weight module is abnormal, it means that the powder weight module is not installed in place in the machine housing. The sensor can be a force sensor, a photoelectric sensor, an image recognition sensor or the like arranged at the powder weight module.

[0200] When it is confirmed that the powder weight module has been installed in the machine housing and installed in place in the machine housing, it is necessary to confirm whether the powder weight module is enabled with the weighing mode. As known from the above, the powder weight module is optionally provided with a weighing mode and a non-weighing mode. When in the weighing mode, the powder weight module can measure the weight of the powder received and transferred; when in the non-weighing mode, the powder weight module can receive the powder or only serve as a communication pipeline for the powder to flow from the outlet end of the grinding module to the inlet end of the brewing module.

[0201] When it is confirmed that the powder weight module has been enabled with the weighing mode, further, the weighing value of the powder weight module can be first zeroed as described above. Then, the weight of the powder received by the powder weight module can be measured in real time during the process that the grinding module continuously discharges the powder to the powder weight module, to form the actual powder weight. When the actual powder weight of the powder received by the powder weight module gradually increases to reach a preset powder weight value, the preset powder weight of the powder is locked by controlling the grinding module to stop grinding and discharging the powder, and / or by controlling the powder weight module to stop receiving the powder, and the preset powder weight of the powder is transferred to the brewing module for the brewing module to perform the brewing and extraction operation on the preset powder weight of the powder.

[0202] In the brewing and extracting process of the brewing module, the coffee liquid is discharged outwards through the beverage outlet, and the liquid continues to be discharged. At this time, the actual liquid weight is measured by the liquid weight module which is externally arranged at the beverage outlet of the beverage cooking equipment. The liquid weight module has an enabled state of moving to the lower side of the beverage outlet and a storage state of moving away from the lower side of the beverage outlet, and the liquid weight module is designed to have a time mode and a non-time mode. Based on this, after the beverage preparation mode is run, and before 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 actual extraction time required" is performed, it further includes:

[0203] Step S240: control the brewing module to start working and discharge the extracted beverage to the liquid weight module, and control the brewing module to stop working when the liquid weight of the beverage received by the liquid weight module reaches the preset liquid weight.

[0204] In this embodiment, for example, when the powder weight module has already received the powder material meeting the preset powder weight, the brewing module is controlled to start running at the same time, before or after a certain time delay after the powder material is transferred from the powder weight module to the brewing module. After the above-mentioned pressing into a cake, wetting and other extraction operations, the beverage prepared by the brewing module is discharged outwards through the beverage outlet, received by the liquid weight module and weighed.

[0205] Before the step of discharging the beverage outwards through the beverage outlet, it further includes:

[0206] Step S241: detecting whether the liquid weight module is currently in the enabled state;

[0207] Step S242: determining whether to enable the timing mode when the liquid weight module is in the enabled state; and,

[0208] Step S243: when the liquid weight module enables the timing mode, obtaining the actual extraction time required from when the liquid weight module detects the liquid weight to when the actual liquid weight reaches the preset liquid weight.

[0209] In this embodiment, 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 the disabled state, for example, it is flipped from one side of the receiving table to close to the front panel of the machine shell, which does not hinder the normal discharge of the beverage outlet, and helps to simplify the space occupation of the receiving table. In step S241, it is first necessary to confirm whether the liquid weight module is in the enabled state. Similarly, the confirmation process can be realized based on a preset sensor. The sensor can be a force sensor, a photoelectric sensor, an image recognition sensor, etc. arranged at the powder weight module.

[0210] For the actual extraction duration, the detection can be based on the timer of the peripheral device. In order to make the detection result of the actual extraction duration more accurate, in the 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. Thus, in step S242, it is first determined whether the liquid weight module is enabled to use the timing mode.

[0211] When the liquid weight module is in the enabled state and the timing mode is enabled, the liquid weight module starts to weigh the coffee liquid in real time and count the time until the actual liquid weight of the coffee liquid reaches the preset liquid weight, and the timing is stopped.

[0212] Specifically, the above-mentioned any extraction duration obtaining step, for example, the preset extraction duration obtaining step performed in step S100, and / or the actual extraction duration obtaining step in step S200, can be obtained in various ways:

[0213] For example, one of the ways can specifically include:

[0214] Step S251: recording a first time point when the liquid weight module receives the first drop of beverage discharged outward through the beverage outlet;

[0215] Step S252: stopping the liquid discharge and recording a second time point when the weight of the beverage received by the liquid weight module reaches the preset liquid weight;

[0216] Step S253: calculating the duration between the first time point and the second time point as the extraction duration.

[0217] In the embodiment, when the first drop of coffee liquid is discharged outward 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 outward 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, i.e. when the last drop of coffee liquid is discharged outward 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 the extraction duration (which can be the actual extraction duration).

[0218] It should be noted that the actual extraction duration obtained by the above-mentioned method does not include the pre-soaking time and the water stop time after pre-soaking, because the liquid weight module cannot measure the parameters of the pre-soaking time and the water stop time after pre-soaking.

[0219] Of course, there is also a second way: in order to achieve the same effect, the pre-soaking time and the water-off time after pre-soaking are also added to the actual extraction time by using other timing devices or flow meter devices to control the overall brewing time, which can also be another embodiment of the present application for measuring the extraction time. In the brewing module, as described above, the water pump is provided in the water circuit, and the start time of the water pump and / or the start-stop time of the electromagnetic valve provided in the brewing water circuit between the water pump and the brewing cylinder are used to calculate the extraction time (which can be the actual extraction time).

[0220] As described above, the water pump can be selectively operated in the pre-soaking program and the extraction program, and the water-off time after pre-soaking is selectively provided between the pre-soaking program and the extraction program. At this time, when the actual extraction time is determined by the start-stop time of the water pump, the actual extraction time can or can not include the running time of the pre-soaking program and the water-off time after pre-soaking. Therefore, the preset extraction time corresponding to the actual extraction time needs to consistently include or not include the running time of the pre-soaking program and the water-off time after pre-soaking to ensure the accuracy of the debugging operation. At this time, the water-off time can be any suitable natural number, including the value zero.

[0221] Step S300: comparing the actual extraction time and the preset extraction time, and instructing to adjust the grinding gap of the cutter head when the extraction time difference between the actual extraction time and the preset extraction time exceeds the time difference threshold.

[0222] It can be understood that when the actual extraction time and the preset extraction time are both known, the size relationship between the two may appear the following cases:

[0223] The extraction time difference between the actual extraction time and the preset extraction time is within the time difference threshold. At this time, it includes the case that the actual extraction time and the preset extraction time are exactly the same, and also includes the case that the actual extraction time and the preset extraction time are similar. That is, the current running condition of the grinding module basically meets the preset, the grinding gap is kept within the appropriate range, and the present situation can be maintained without further adjusting the grinding gap.

[0224] The extraction time difference between the actual extraction time and the preset extraction time exceeds the time difference threshold, and the actual extraction time is greater than the preset extraction time. The extraction time difference between the actual extraction time and the preset extraction time exceeding the time difference threshold indicates that the current running condition of the grinding module is abnormal. Since there is no other condition abnormal parameter value, the finer the ground coffee powder, the more difficult it is for the coffee powder to form a gap for water to flow through after being pressed into a cake, resulting in a slower extraction speed and an extended extraction time. Therefore, when the actual extraction time is greater 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.

[0225] The extraction 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. As described above, the extraction time difference between the actual extraction time and the preset extraction time exceeding the time difference threshold indicates that the current operation of the grinding module is abnormal. Without adding other condition abnormal parameter values, the coarser the ground coffee powder, the easier it is to form gaps for water to flow through after the coffee powder is pressed into a cake, 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 adjusted smaller.

[0226] In view of the above, when the grinding gap is abnormally large or small, in order to better achieve the adjustment of the grinding gap, step S300 further comprises:

[0227] Step S310: When the extraction time difference between the actual extraction time and the preset extraction time exceeds the time difference threshold, obtaining preset mapping correlation data of the extraction time difference and the adjustment amount of the grinding gap;

[0228] Step S320: According to the mapping correlation data and the current extraction time difference, obtaining a target adjustment amount of the grinding gap; and,

[0229] Step S330: Adjusting the grinding gap according to the target adjustment amount.

[0230] In this embodiment, the machine will have preset mapping correlation data of the extraction time difference and the adjustment amount of the grinding gap. When either the extraction time difference or the adjustment amount of the grinding gap is known, the other can be accurately and uniquely obtained through the mapping correlation data. The specific form of the mapping correlation data is not limited, and can be a function relationship, a point graph or a line graph, or a table integrated with a large amount of required data, so that the step of repeatedly adjusting the grinding gap can be reduced as much as possible according to the mapping correlation data.

[0231] Preferably, after the beverage preparation device is adjusted by the grinding gap, and the actual extraction time reaches the preset extraction time range, the grinding gap needs to be adjusted coarser by 5 steps, and then finer by 5 steps. During the adjustment of the grinding gap, the grinding module continues to work, and the residual powder in the grinding module and the powder discharged from the grinding module after the adjustment of 5 steps are discharged from the grinding module, and the beverage extraction is performed again to further determine whether the extraction time is within the preset extraction time range. If it is within the range, it indicates that the calibration is complete, and if the extraction time is not within the preset extraction time range, the above process is continued to recalibrate, wherein the adjustment of the coarser and finer steps or the grinding gap can be set to another value according to the needs, which is not described here.

[0232] Preferably, in the test and adjustment process, as long as the coarse and fine adjustment is carried out, that is, the grinding gap is adjusted, if the particle size of the powder is coarsely adjusted, that is, the grinding gap adjustment is increased, the grinding gap adjustment motor works, and the grinding module can not need to work, that is, the powder is not ground; or the powder can continue to be ground. Conversely, if the separation particle size is finely adjusted, that is, the grinding gap adjustment is reduced, the grinding gap adjustment motor and the grinding module need to work at the same time, and the grinding module is in a continuous running 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 discharged first. When the grinding module continuously runs to meet the preset running condition, it is generally considered that the residual powder in the grinding module has been discharged. In the embodiments of the present application, the preset running condition includes reaching a preset running time or obtaining a powder weight value of a preset weight. Specifically, for example, the grinding module can be continuously started for 8 seconds or the powder weight obtained by the powder weight module reaches 15g, then the powder in the powder weight module is discharged, and the next test or is carried out.

[0233] The mapping correlation data can be obtained directly by recording experience data obtained from user experience, or by a large number of experiments, or by simulation fitting data, etc. The mapping correlation data is stored in the memory 150 of the control device 100, and can be retrieved and compared when needed.

[0234] Based on this, first, the step of calculating the current extraction time difference between the actual extraction time and the preset extraction time in step S310 is performed. When the current extraction time difference is determined, the target adjustment amount of the grinding gap corresponding to the current extraction time difference can be obtained by querying and comparing the above mapping correlation data. Finally, the current gap value of the cutter head 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 right position.

[0235] In the above, the way of adjusting the cutter head grinding gap includes user manual input, control device automatic updating and replacing the cutter head grinding gap parameters, etc.

[0236] In the technical scheme provided in the present application, in the process of preparing the beverage, the correlation between the grinding gap and the extraction time is high when the actual powder weight is equivalent to the preset powder weight and the actual liquid weight is equivalent to the preset liquid weight. Therefore, by comparing the actual extraction time with the preset extraction time, the grinding gap can be directly determined whether it needs to be adjusted and how to adjust it, and the debugging process is relatively simpler and more reliable.

[0237] In addition, it is to 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 value is reached, the conclusion can be determined directly after step S200 is performed, i.e., the cutter disc grinding gap is not abnormal; or the conclusion can be determined when the cutter disc grinding gap is initially abnormal during the execution of step S300, but the grinding gap is adjusted to be in place after at least one adjustment of the grinding gap. After the conclusion that the extraction time difference between the actual extraction time and the preset extraction time does not exceed the time difference threshold value is reached, the following operations can be performed:

[0238] Step S410: When the extraction time difference between the actual extraction time and the preset extraction time does not exceed the time difference threshold value, the grinding time required to reach the preset powder weight or the grinding efficiency value converted therefrom is obtained and recorded in real time.

[0239] Step S420: When the grinding time is higher than the time preset threshold value or the grinding efficiency value is lower than the efficiency preset threshold value, a prompt information for replacing the cutter disc is issued.

[0240] In the embodiment, when the extraction time difference between the actual extraction time and the preset extraction time does not exceed the time difference threshold value, the beverage preparation mode is re-run, and the actual grinding time required to obtain the preset powder weight is recorded during the grinding of the coffee beans by the grinding module. 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 the efficiency changes trigger the preset threshold value, i.e., when the grinding time is higher than the time threshold value or the grinding efficiency value is lower than the efficiency threshold value, it indicates that the grinding module is abnormal and cannot meet the required, and the possible reason is that the cutter disc is excessively worn and is not suitable for continued use, and the cutter disc needs to be replaced. At this time, the control device 100 issues a prompt information for replacing the cutter disc, wherein the grinding parameters for prompting the replacement of the cutter disc include the grinding time or the grinding efficiency. The threshold value for warning the life of the cutter disc is 50% higher than the preset time threshold value or 50% lower than the preset efficiency threshold value. The prompt information can be presented in any suitable manner. For example, when the shell is externally provided with a display and control module, 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 in communication connection with the control device 100, etc. The control device can be remotely monitored and the running state of the powder weight module and the liquid weight module can be obtained, and the fault reason can be obtained when the powder weight module and the liquid weight module fail.

[0241] Based on the above embodiments, it can be understood that during the entire process of running the beverage preparation mode, not only the knife disc, powder weight module, liquid weight module and other mechanisms are involved, but also components such as water supply assembly, powder pressing mechanism are involved. Therefore, in order to make the measurement results of steps S100 to S300 provided in the embodiment more accurate, during the process of running the beverage preparation mode, the following steps are further included:

[0242] Step V100: obtaining a preset value of a running parameter of a running module, the running module including a grinding module, a brewing module, a powder weight module and / or a liquid weight module, the running parameter including a knife disc grinding start time and / or a total water inlet amount L and / or a powder cake thickness; and,

[0243] Step V200: during the process of running the beverage preparation mode, obtaining an actual value of the running parameter, and when the deviation of the actual value from the preset value exceeds a deviation threshold, stopping running and performing fault warning on the running module associated with the running parameter;

[0244] Step V300: during the process of running the beverage preparation mode, obtaining an actual value of the running parameter, and when the deviation of the actual value from the preset value does not exceed the deviation threshold, continuing to run the subsequent operation.

[0245] In the embodiment, the running parameter mainly refers to other parameter values that may affect the correlation between the extraction time and the grinding gap in addition to the powder weight and the liquid weight, which can be set according to the actual preparation process, the actual application scenario, the actual preparation demand, etc. In theory, during the entire process from the start of the grinding module to the last drop of coffee liquid being discharged out of the beverage outlet during the execution of the beverage preparation mode, the abnormality of the running parameter of all the running modules participating in the running 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 parameter can include but is not limited to the knife disc grinding start time, the total water inlet amount L, the powder cake thickness M, etc.

[0246] By monitoring and obtaining the actual value of one or more running parameters, the actual value is compared with the pre-stored preset value. When the actual value meets the corresponding preset value, that is, the running parameter corresponding to the actual value is within the normal range, the remaining steps of step S200 and subsequent step S300 can be continued to be executed; otherwise, when the actual value does not meet the corresponding preset value, that is, the running parameter corresponding to the actual value is abnormal, the abnormality needs to be investigated first, and then the remaining steps of step S200 and subsequent step S300 are executed after ensuring that the actual value of the running parameter meets the corresponding preset value.

[0247] Specifically, the beverage processing device of the present application is provided with a powder weight module and a liquid weight module and a measurement of the matching extraction time, which can realize the adjustment of the grinding gap of the grinding module to affect the fineness of the ground powder. After the determination of the powder weight, liquid weight and extraction time, the beverage processing device can preset or set the sensors, timers, flow meters and other devices of each module connected with the processor 110, part of which can refer to the parameter types and numerical ranges of the above modules.

[0248] Preferably, the powder weight detected by the powder weight module is used to calculate the starting grinding time of the single grinding module, and the starting grinding time is stored as a preset value in the control device of the beverage processing device. When the weighing data of the powder weight module is within the controllable deviation range of the preset data, but the actual starting grinding time of the grinding module deviates from the preset starting grinding time, it is inferred that the powder weight module is faulty, and a warning prompt is given.

[0249] Preferably, the total water inflow L required for single extraction is obtained according to the fixed powder weight, liquid weight and fixed extraction time, and stored as a preset value in the beverage processing device. When the weighing data of the liquid weight module is within the controllable deviation range of the preset data, but the actual total water inflow deviates significantly from the preset total water inflow L, it is inferred that the powder weight module is faulty, and a warning prompt is given. Further, the powder cake thickness is detected, if the powder cake thickness deviates, it is inferred that the powder weight module is faulty, and a warning prompt is given. If the powder cake thickness does not deviate, but the total water inflow deviates, it is inferred that the liquid weight module is faulty, and a warning prompt is given. The above fault detection and prompt of the powder weight module and the liquid weight module require that the grinding gap of the grinding module has not changed.

[0250] Preferably, the brewing cylinder of the brewing module can measure the powder cake thickness after the powder weight, liquid weight and fixed extraction time parameters are preset, and form a preset powder cake thickness as a preset value stored in the beverage processing device. When the actual measured powder cake thickness is greater than the preset powder cake thickness, it is inferred that the powder weight module is faulty, and a warning prompt is given.

[0251] Further, if the grinding gap of the grinding module is not adjusted, and both the powder cake thickness and the powder weight value detected by the powder weight module are abnormal, and the actual extraction time or extraction flow rate or extraction pressure data is abnormal, the system will push a bean product abnormal prompt in the bean bin to prompt the user whether to replace or add new bean product, and further prompt whether to perform a grinding gap calibration again to ensure that the actual extraction time or extraction flow rate or extraction pressure data is consistent with the preset value.

[0252] The above prompt information can be presented in any suitable manner. For example, when the shell is externally provided with a display module, 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 in communication connection with the control device 100, etc.

[0253] It should be noted that the above beverage preparation device debugging method can be performed simultaneously when the beverage preparation device is running in a preset working mode, and / or when a debugging program is called, and / or automatically after the beverage preparation device is restarted, without limitation.

[0254] In the beverage preparation device of the present application, the liquid weight module is provided to accurately match the weight of the milk beverage to be mixed, so as to realize beverages such as latte and cappuccino, in which coffee is mixed with milk. Some beverages are prepared by first extracting coffee liquid and then preparing milk, or by first preparing milk and then extracting coffee. It can be understood that, regardless of which one is prepared first, the preparation can be performed using the superimposed measurement of the liquid weight module to accurately match the beverage, and the amount of milk can be accurately controlled to avoid waste and uneven matching of the prepared beverage.

[0255] In view of the above, when the beverage preparation device includes a plurality of bean hoppers, and different bean hoppers are used to store different types of coffee beans, different beverages can be obtained one by one when the coffee beans in each bean hopper are used as raw materials to run the beverage preparation mode. It can be understood that the preparation process of each different beverage can be respectively configured with the control program of the above beverage preparation device according to actual needs. When the coffee beans in different bean hoppers need to be replaced to run the beverage preparation mode, different parameter settings need to be called to perform grinding, extraction, etc. so that the preparation process of different coffee beans automatically matches the most suitable extraction parameters and processes. When the debugging program corresponding to the different coffee beans in different bean hoppers is completed, the above parameters corresponding to the debugging program can be stored in the memory 150 without manual modification. When the beverage preparation mode is subsequently run corresponding to different bean hoppers, the most suitable extraction parameters and processes after debugging can be automatically called.

[0256] The above beverage preparation device debugging method provided by the present application is used in a fully automatic coffee machine, or the beverage preparation device combining the bean grinder 200 and the brewing machine 300 is named as CLS (Closed-Loop System) closed-loop control system technology, which is used for beverage preparation device testing and real-time automatic adjustment, and can realize one-key calibration to meet the quality control of each cup of beverage in long-term and high-frequency use.

[0257] The beverage preparation device of the present application 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 beverage in multiple beverages corresponding to the bean bin or grinding module set, for example, after the extraction scheme associated with different types of beverages corresponding to the grinding module is automatically adjusted, other types of beverages corresponding to the grinding module need to be adjusted again.

[0258] The CLS closed loop control system function is integrated in the beverage preparation device in a programmatic manner, and can be opened or closed during actual operation of the blade adjustment operation.

[0259] Further, in the conventional beverage preparation device, there is no matching relationship between the modules of the device, and for an abnormal parameter, it is possible that one of the multiple components causes it, but it is often difficult to quickly determine which component causes it, which causes waste of time during maintenance of the device, and the loss caused by the idle time of the device during maintenance also increases.

[0260] The beverage preparation device of the present application can realize intelligent upgrading of the beverage preparation device after matching the internal other part parameter detection of the powder weight module and / or the liquid weight module, can intelligently monitor each module of the beverage preparation device, and can quickly determine the abnormal module when the corresponding parameter is abnormal, to realize fast and accurate identification.

[0261] The device adjustment method of the present application can be applied to the following scenarios:

[0262] 1. Active calibration, mainly used for R&D personnel debugging, testing, factory parameter calibration, pre-set parameter setting calibration before use, etc.

[0263] 2. For commercial use, daily pre-opening self-check or on-site maintenance and adjustment by maintenance personnel, etc., wherein the program can be selected to be executed at least once before the machine is restarted each time.

[0264] 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 after grinding by the grinding module is different, and needs to be recalibrated.

[0265] 4. For commercial use, real-time monitoring and calibration to ensure the stability of the product.

[0266] Referring to FIG. 15, at least part of the parameter values are adjustable parameters on the CLS control panel of the full-automatic coffee machine of the present application. Specifically, in an embodiment, the CLS control interface is divided into multiple regions Q:

[0267] Q1 region is a bean bin prompt region. Different color blocks corresponding to different bean bins are displayed in this region. When one color block is lit or its color or state changes obviously, it indicates that the current calibrated CLS is bound to the bean bin.

[0268] Q2 region is a CLS input (target value, i.e., the preset value described above) region. In this region, the CLS input preset value can be, but is not limited to, coffee liquid weight (i.e., preset liquid weight), coffee powder weight (i.e., preset powder weight), liquid output time (i.e., preset extraction time), and blade scale. When the coffee liquid weight (i.e., preset liquid weight), coffee powder weight (i.e., preset powder weight), and liquid output time (i.e., preset extraction time) are input, the above debugging program is started. Generally, the blade scale cannot be input, and the CLS scale is 0 when the CLS is started, serving as a reference.

[0269] Q3 region is a CLS test (actual value) region. In this region, the CLS input debugging actual value can be, but is not limited to, coffee liquid weight (i.e., actual liquid weight), coffee powder weight (i.e., actual powder weight), liquid output time (i.e., actual extraction time), and blade scale, which are all actual data measured each time the debugging is performed. When the actual value is consistent with the preset value (or within the preset tolerance range), the debugging operation stops.

[0270] Q4 region is a debugging input button region, above which the number of debugging times is displayed.

[0271] Q5 region is a beverage data region. In this region, the beverage data can be, but is not limited to, water quantity, coffee powder quantity, pre-soaking time, post-pressing distance, bypass water quantity, and other data, which are associated with the beverage preparation mode. The data in the above CLS test region are automatically recorded, updated, or replaced.

[0272] Q6 region is a display region of multiple different beverage interfaces. When the region differs, the debugging program is automatically started, or a pop-up prompt appears, prompting the user to press the input to start the debugging program.

[0273] Q7 region is a CLS icon display region. When the CLS icon is displayed in this region, it indicates that the entire machine is currently in the CLS automatic debugging program.

[0274] Preferably, to enable the CLS program, the quantity of beans in the corresponding bean bin needs to reach a certain value to meet the quantity required for the CLS program to complete a complete calibration. Preferably, before starting the CLS program, the system prompts the operator to visually estimate the quantity of beans according to a reference, or a position sensor, a weight sensor, or the like is arranged in the bean bin as a detection method.

[0275] In a preferred embodiment, the debugging method of the beverage preparation device can further perform the following steps:

[0276] Step S900: complete the setting input of the above-mentioned pre-parameters;

[0277] Step S901: select the beverage to be tested, continuously make N cups, take the average of the preset extraction time, 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;

[0278] Step S902: when the numerical fluctuation of the standard deviation is too large, push the confirmation information, and the operator needs to confirm whether it is abnormal.

[0279] In the debugging method program of the present application, 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 is 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.

[0280] Further, the beverage preparation device of the present application is provided with a plurality of bean hoppers and a grinding module corresponding to each bean hopper, wherein each bean hopper can be bound to a plurality of different types of beverages. Referring to FIG. 16, the beverage preparation device includes a touchable display operation interface (i.e., the following control interface). The control interface can select to enter the page of the beverage preparation device debugging. As shown in FIG. 16, the D1 area in the control interface displays the preset each bean hopper (for example, left bean hopper and right bean hopper) of the current beverage preparation device; the D2 area displays the blade disc adjustment trigger button (for example, left blade disc adjustment and right blade disc adjustment) of each grinding module corresponding to each bean hopper, which can realize manual adjustment of the blade disc parameter; the D3 area displays the CLS start and close trigger button of each bean hopper; the D4 area displays the CLS calibration trigger button of each bean hopper, which can enter the CLS debugging interface. The system settings can be selected, for example, as shown in FIG. 17: when the debugging method corresponding to the bean hopper or the grinding module is enabled, the manual adjustment of the blade disc grinding gap is not allowed, and a page prompt is popped up, which can provide the selection of confirming to exit the manual adjustment or selecting to close the CLS debugging program.

[0281] The corresponding beverage entering parameter debugging interface of the bean bin or the bean bin below can be selected. Among them, the corresponding bean bin or the grinding module unique to the bean bin can be selected to enter the debugging interface. As shown in FIG. 18, in the debugging page, Y area displays a plurality of beverages; Y0 area displays the currently selected target beverage; and Z area is each beverage parameter corresponding to the currently selected target beverage. Specifically, a plurality of beverages corresponding to the bean bin are displayed on the page, and the beverage can be selected according to the bean bin, or the bean bin can be matched according to the selected beverage to trigger the corresponding debugging program. After the debugging is completed, all beverages under the bean bin or the grinding module are locked, and a plurality of different types of beverages bound by each of the bean bins are compared with the selected debugging beverage in terms of preset parameters such as cake parameters and extraction parameters to obtain the preset extraction time of the selected beverage to match the debugging method directly reused for other types of beverages. Among them, any parameter adjustment will cause the online debugging program to be invalid.

[0282] Please refer to FIG. 18, 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 associatedly arranged as a block, a plurality of blocks can be arranged in the debugging interface, and the plurality of blocks can be arranged linearly or in an array.

[0283] Specifically, the beverage after the program adjustment or the beverage after the debugging method reuse forms a corner mark Q around the icon Y of the beverage to prompt that the beverage is debugged and can be used as the calibration of the grinding gap of the cutter disc. The corner mark can be at least one or a combination of graphics, colors or dynamics. After the beverage with the corner mark is selected for extraction, the actual extraction time is monitored during the making of the beverage with the corner mark, as shown in FIG. 19. 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 information.

[0284] In the beverage cooking equipment of the present application, a code scanning device can also be provided. When the bean bin is replenished or the raw material is replaced, the new bean product can be scanned and identified to quickly adjust the grinding gap of the cutter disc and match the corresponding raw material.

[0285] In the preferred embodiment, the debugging method of the beverage cooking equipment described in the present application needs to be entered by the administrator to execute debugging, calibration and the like. During the daily operation and maintenance, the page prompts or warns in time, and the beverage cooking equipment cannot be directly entered into the system for debugging.

[0286] In the embodiment of the present application, a flow limiting hole is arranged in the waterway pipeline of the brewing module. During the parameter calibration and detection in the above-mentioned extraction program, the flow rate of the flow limiting hole is preferentially detected whether it is within the normal value range.

[0287] Before starting the commissioning method of the beverage preparation apparatus in the present application, it must be confirmed that the module capable of detecting the powder cake parameters has been installed and activated, i.e. the powder weight module and / or the powder cake thickness detection is activated, and before using the commissioning method involving the liquid weight parameters, it must be confirmed that the liquid weight module for weighing the liquid weight is activated.

[0288] The extraction parameters can include the liquid weight parameters obtained by the liquid weight module or the liquid volume for extraction detected by the set total water volume.

[0289] In view of the above, the extraction duration can be detected by setting or activating the liquid weight module, or the water pump or electromagnetic valve start-stop time of the brewing module is used to confirm the extraction duration.

[0290] In addition, it needs to be pointed out that the various parameters mentioned above, such as powder weight, liquid weight, extraction duration, etc., can refer to relatively fixed point values, or data ranges composed of part of fixed point values, without limitation.

[0291] Second application example:

[0292] Please refer to FIGS. 2-4, in the present design, the control method of the beverage preparation apparatus is specifically a commissioning method of the beverage preparation apparatus.

[0293] Please refer to FIG. 2, the commissioning method of the beverage preparation apparatus includes:

[0294] Step K100: running the beverage preparation mode, first performing a blade grinding duration adjustment step for adjusting the blade grinding duration;

[0295] Step K200: after confirming that the blade grinding duration does not need to be adjusted or the blade grinding duration adjustment is in place, performing a blade grinding gap adjustment step for adjusting the blade grinding gap.

[0296] In the present embodiment, when the commissioning instruction of the beverage preparation apparatus is triggered, the beverage preparation mode can be associated with the running. The triggering mode of the commissioning instruction is not limited, for example, it can be triggered by the user based on the preset key on the control module externally mounted on the shell, triggered based on the preset program on the mobile terminal in communication connection with the control device 100, triggered by issuing a preset voice or making a preset action, etc. According to actual needs, the commissioning instruction can be subdivided into different commissioning instructions corresponding to different commissioning objects. In the present embodiment, the commissioning instruction is mainly used to commission the two blade grinding durations in the grinding module and the blade grinding gap between the two blades.

[0297] The beverage preparation mode is a complete routine process of the whole machine for beverage preparation, including grinding, powder taking, powder pressing, extraction and other operations, so that the final debugging result can be directly saved and adapted for the routine beverage preparation mode.

[0298] When the debugging instruction is triggered, the control device 100 first controls the execution of the blade grinding time length adjustment step, and then executes the blade grinding gap adjustment step after the blade grinding time length is preliminarily adjusted in place.

[0299] Specifically, please refer to FIG. 3, in the design, the blade grinding time length adjustment step includes:

[0300] Step A100: obtaining a preset cake thickness and an actual cake thickness;

[0301] Step A200: when the thickness difference between the actual cake thickness and the preset cake thickness exceeds a thickness difference threshold, adjusting the blade grinding time length, until the thickness difference does not exceed the thickness difference threshold, determining that the blade grinding time length adjustment is in place.

[0302] It can be understood that the obtaining method of the preset cake thickness is not limited: it can be stored in the memory 150 of the control device 100, and when needed, the corresponding data can be called out from the memory 150 by the processor 110. Or it can also be obtained by the user by entering on site or pre-entering based on the above method. At this time, the user can enter the corresponding data through active reminding of the user based on the input module before or during the current debugging operation, or the user actively enters the corresponding data based on the input module. Among them, there are many ways to remind the user, which can be but not limited to the light signal of the warning light, the prompt sound of the buzzer, the message push received by the mobile terminal in communication connection with the control device 100, etc.

[0303] Specifically, the step of adjusting the blade grinding time length in A200 includes:

[0304] Step A210: when the thickness difference between the actual cake thickness and the preset cake thickness exceeds the thickness difference threshold, and the actual cake thickness is greater than the preset cake thickness, reducing the blade grinding time length; or,

[0305] Step A220: when the thickness difference between the actual cake thickness and the preset cake thickness exceeds the thickness difference threshold, and the actual cake thickness is less than the preset cake thickness, increasing the blade grinding time length.

[0306] In this embodiment, when the actual cake thickness and the preset cake thickness are both known, the size relationship between them may appear the following cases:

[0307] The thickness difference between the actual cake thickness and the preset cake thickness is not beyond the thickness difference threshold value, which can be completely the same or have some difference. At this time, it means that the current running condition of the grinding module basically meets the preset, the cutter disc grinding time is kept within the appropriate range, and the status quo can be maintained without adjusting the cutter disc grinding time.

[0308] The thickness difference between the actual cake thickness and the preset cake thickness is beyond the thickness difference threshold value, and the actual cake thickness is greater than the preset cake thickness. The difference between the actual cake thickness and the preset cake thickness means that the current running condition of the grinding module is abnormal. Since the longer the cutter disc grinding time is, the more coffee powder is obtained under the same other conditions, the cake thickness is thicker after the coffee powder is pressed into a cake. Therefore, when the actual cake thickness is greater than the preset cake thickness, it means that the amount of coffee powder currently ground by the grinding module is too much, and the cutter disc grinding time needs to be appropriately shortened.

[0309] The thickness difference between the actual cake thickness and the preset cake thickness is beyond the thickness difference threshold value, and the actual cake thickness is less than the preset cake thickness. As described above, the difference between the actual cake thickness and the preset cake thickness means that the current running condition of the grinding module is abnormal. Since the shorter the cutter disc grinding time is, the less coffee powder is obtained under the same other conditions, the cake thickness is thinner after the coffee powder is pressed into a cake. Therefore, when the actual cake thickness is less than the preset cake thickness, it means that the amount of coffee powder currently ground by the grinding module is too small, and the cutter disc grinding time needs to be appropriately extended.

[0310] In view of the above, please refer to FIG. 4 for details. The cutter disc grinding gap adjustment step includes:

[0311] Step B100: Obtain a preset extraction time and an actual extraction time.

[0312] Step B200: When the extraction time difference between the actual extraction time and the preset extraction time is beyond the time difference threshold value, adjust the cutter disc grinding gap until the extraction time difference is not beyond the time difference threshold value, and determine that the cutter disc grinding gap adjustment is in place.

[0313] In this embodiment, the preset extraction time can be determined before or at the same time as step B100 is performed, and the actual extraction time can be determined during each operation of the beverage preparation mode. In order to improve the measurement accuracy of the actual extraction time, in actual application, in addition to the preset extraction time, the weight value of the powder discharged outward by the grinding module and the weight value of the beverage discharged outward by the brewing module can be further measured to comprehensively limit the measurement of the actual extraction time.

[0314] At this time, the above steps about B100 can also be specific embodiments of the "debugging method of the beverage processing device" in the first application instance. That is, the above steps S and steps V are each embodiment.

[0315] In addition, it needs to be pointed out that in the process of performing the adjustment step of the cutter disc grinding gap, the following steps are also included:

[0316] When the actual powder weight reaches the preset powder weight, and the thickness difference between the actual powder cake thickness and the preset powder cake thickness exceeds the thickness difference threshold, an abnormal prompt of the powder weight module is issued.

[0317] In this embodiment, when the powder material received by the powder weight module is determined to reach the preset powder weight, the powder material is transferred to the brewing cylinder, and the powder material is pressed to form a powder cake by the powder pressing module. In this process, no other mechanism is involved in operation. At this time, if the powder cake thickness is abnormal, that is, the thickness difference between the actual powder cake thickness and the preset powder cake thickness exceeds the thickness difference threshold, it can be basically determined that the weighing of the powder weight module is abnormal, and a related warning can be issued to prompt the user to perform corresponding calibration processing.

[0318] It can be understood that in the above adjustment step of the cutter disc grinding time, the adjustment of the cutter disc grinding time can be completed at one time, that is, after performing the steps of A100 to A200 once, the beverage preparation mode is re-run, and it is confirmed that the actual powder cake thickness of this time is the same as the preset powder cake thickness, that is, the cutter disc grinding time is adjusted to the right, and the adjustment step of the cutter disc grinding time is ended.

[0319] However, generally, in the above adjustment step of the cutter disc grinding time, the adjustment of the cutter disc grinding time cannot be completed at one time and needs to be repeated in several times, that is, the steps of A100 to A200 are repeatedly executed. It can be understood that after one flow of A100 to A200 is completed and the cutter disc grinding time is adjusted once, the beverage preparation mode needs to be re-run and enter the next flow of A100 to A200 to adjust the cutter disc grinding time twice... Such circulation is repeated until it is confirmed that the actual powder cake thickness of the last time is the same as the preset powder cake thickness, that is, the cutter disc grinding time is adjusted to the right, and the adjustment step of the cutter disc grinding time is ended.

[0320] Similarly, in the above adjustment step of the cutter disc grinding gap, the adjustment of the cutter disc grinding gap can be completed at one time, that is, after performing the steps of B100 to B200 once, the beverage preparation mode is re-run, and it is confirmed that the actual extraction time of this time is the same as the preset extraction time, that is, the cutter disc grinding gap is adjusted to the right, and the adjustment step of the cutter disc grinding gap is ended.

[0321] But generally, in the above adjustment steps of the blade disc grinding gap, the adjustment of the blade disc grinding gap is difficult to be completed at one time and needs to be repeatedly executed in several times, that is, the steps of B100 to B200 are repeatedly executed. It can be understood that when one process of B100 to B200 is completed, the blade disc grinding gap is adjusted once, and the beverage preparation mode needs to be re-run and enter the next process of B100 to B200 to adjust the blade disc grinding gap twice. … Such as in turn, until the actual extraction time of the last time is confirmed to be the same as the preset extraction time, that is, the blade disc grinding gap is adjusted to the right, and the adjustment steps of the blade disc grinding gap are ended.

[0322] In view of the above, in the whole process of repeatedly executing the adjustment of the blade disc grinding gap in several times, one or several adjustment steps of the blade disc grinding time can be interspersed according to actual needs, that is, whether the actual cake thickness is still the same as the preset cake thickness and whether the blade disc grinding time is still accurate and meets the needs before adjusting the blade disc grinding gap.

[0323] The frequency of the above interspersed execution is not limited, and one adjustment step of the blade disc grinding time can be performed after repeatedly executing the adjustment step of the blade disc grinding gap several times.

[0324] But preferably, in an embodiment, at least one adjustment step of the blade disc grinding time needs to be executed before repeatedly executing one adjustment step of the blade disc grinding gap each time. Specifically, when the steps of A100 to A200 are executed to ensure that the blade disc grinding time is adjusted to the right for the first time, the first process steps of B100 to B200 are executed, and the blade disc grinding gap is adjusted for the first time. After re-running the beverage preparation mode, the steps of A100 to A200 are executed again to ensure that the blade disc grinding time is adjusted to the right for the second time, and the second process steps of B100 to B200 are executed to adjust the blade disc grinding gap for the second time. … In this way, it can be ensured that the blade disc grinding time is accurate and reliable before adjusting the blade disc grinding gap each time.

[0325] In view of the above embodiment, before each step of re-running the beverage preparation mode, it further includes:

[0326] The grinding module is controlled to continue to run until it stops running when the preset running condition is met to empty the current residual powder of the grinding module; wherein the preset running condition includes that the grinding module reaches a preset running time or the grinding module obtains a preset weighed powder weight of powder.

[0327] In the embodiment, the residual powder in the corresponding grinding module needs to be discharged clean before the adjustment of the grinding gap of the cutter head of the grinding module is performed at least each time. When the grinding module continues to run to meet the preset running condition, it can be generally considered that the residual powder in the grinding module has been discharged clean. In the embodiment, the preset running condition includes reaching the preset running time or obtaining the powder weight of the preset weighing powder. Specifically, for example, the grinding module can be started for 8 seconds or the powder weight obtained by the weighing module reaches 15 g, then the powder in the weighing module is discharged, and the next cup test is performed.

[0328] Third application example:

[0329] In the design, the control method of the beverage preparation device specifically represents a calibration method of the beverage preparation device.

[0330] Referring to FIG. 5, the calibration method of the beverage preparation device includes:

[0331] Step J100: obtaining a self-selected value of the to-be-calibrated parameter input by the user through the input device, and running the beverage preparation mode according to the self-selected value;

[0332] In the embodiment, the input device can be, for example, the display and control panel described above, which is arranged on the shell of the beverage preparation device and is electrically connected with the control device 100, or a terminal device independent of the beverage preparation device and in wired or wireless communication connection with the control device 100. The terminal device can be fixed or mobile.

[0333] The calibration method of the beverage preparation device can be generally executed at any time after the whole machine is shipped; can also be executed at any time after the whole machine is reset each time; can also be executed when the whole machine is restarted after the interval exceeds the set time, etc. It can be understood that the calibration method of the beverage preparation device is generally executed before the whole machine is formally put into use, to calibrate the running parameters during the formal use of the whole machine and obtain the reference base value of each running parameter.

[0334] In the conventional running state of the beverage preparation device, for example, in the state of running the beverage preparation mode, the base value of multiple running parameters generally needs to be mobilized, so that the beverage prepared each time by running the beverage preparation mode is of the same quality. The running parameters can be, but are not limited to, the powder weight of coffee powder, the liquid weight of coffee liquid, the start grinding time of the cutter head, the grinding gap of the cutter head, the total water amount, the cake thickness, the extraction time, etc.

[0335] But it can be understood that the operation parameters required to be input by the user through the input device in the above step J100 can all be the to-be-calibrated parameters, that is, all are operation parameters that need to be calibrated to obtain the reference value. At this time, the to-be-calibrated parameters can be one or several of the above operation parameters, depending on the different needs of different specifications of beverage cooking equipment.

[0336] For example, when there is only one to-be-calibrated parameter required to be input by the user through the input device, preferably, the to-be-calibrated parameter can be the extraction time. The extraction time is the time required to extract a beverage.

[0337] For example, when there are at least two to-be-calibrated parameters required to be input by the user through the input device, the two to-be-calibrated parameters can be calibrated simultaneously. Or the two to-be-calibrated parameters can be calibrated in sequence or alternately. But preferably, when one of the at least two to-be-calibrated parameters is the extraction time, the calibration priority of the extraction time is higher than that of the other to-be-calibrated parameters, that is, the extraction time is calibrated first.

[0338] At this time, the self-selected value of the to-be-calibrated parameter, for example, the self-selected value of the extraction time, can be directly obtained by the user based on the input device input. The value can be input by the user according to his own experience, obtained by querying other tools, or randomly input, etc.

[0339] In addition, the operation parameters required to be input by the user through the input device in the above step J100 can also be at least one reference parameter and at least one to-be-calibrated parameter. The reference parameter and / or the to-be-calibrated parameter are one of the above operation parameters, depending on the different needs of different specifications of beverage cooking equipment. Among them, the reference parameter is an operation parameter whose value is basically already defaulted to be accurate, or is pre-calibrated to be a reference value. For the convenience of understanding, the input value of the reference parameter is directly defined as the reference value of the reference parameter in the following embodiments. For example, when the reference parameter is the weight of the powder, the input value is the powder weight reference value; when the reference parameter is the weight of the beverage, the input value is the liquid weight reference value.

[0340] Based on this, the above step J100 can specifically include:

[0341] Step J110: Obtain the reference value of at least one reference parameter and a self-selected value of the to-be-calibrated parameter input by the user through the input device, and run the beverage preparation mode according to the reference value and the self-selected value.

[0342] In the embodiment, according to the indication of the operation interface of the beverage preparation device, the user can input the reference value of the reference parameter and the self-selected value of the parameter to be calibrated through the input device. The reference value of the reference parameter can be obtained by default, by user query and input, by system call of stored data, etc. The self-selected value of the parameter to be calibrated is also self-defined and input by the user.

[0343] In actual application, the reference value of the reference parameter input by the user through the input device in step J110 can be two, i.e., the powder weight reference value and the liquid weight reference value. The ratio of the powder weight reference value to the liquid weight reference value can be approximately 1:2. The self-selected value of the parameter to be calibrated can be one, i.e., the extraction time self-selected value.

[0344] Therefore, for obtaining the powder weight reference value, the step of running the beverage preparation mode in step J110 includes:

[0345] Step J111: sequentially control the grinding module and the brewing module to start running, and stop liquid output when the weight of the powder reaches the powder weight reference value, the weight of the beverage reaches the liquid weight reference value, and the actual extraction time reaches the extraction time self-selected value, to obtain the beverage.

[0346] Specifically, when the beverage preparation device is provided with a powder weight module, the powder weight module is arranged at least at the outlet end of the grinding module and can receive the powder discharged outward from the grinding module. At this time, step J111 can be specifically:

[0347] Step J1111: control the grinding module to start grinding and transfer the powder to the powder weight module, and control the grinding module to stop working when the weight of the powder received by the powder weight module reaches the powder weight reference value.

[0348] In the embodiment, the control device controls the grinding module to start running in advance, and before or at the same time, the hopper inputs coffee beans of the required variety and weight to the inlet end of the grinding module. The two knife plates of the grinding module generate relative motion to grind the coffee beans into coffee powder and transfer the coffee powder to the powder weight module. The weighing function of the powder weight module can be started in advance before receiving the powder, at the same time of receiving the powder, or delayed after receiving the powder for a certain time. When the weight value of the received powder reaches the powder weight reference value input by the user through the input device, the control device controls the grinding module to stop working and no longer transfer the coffee powder to the powder weight module.

[0349] Of course, before the step of controlling the grinding module to start grinding and transfer the powder to the powder weight module in step J1111, it also includes:

[0350] Zero the weighing value of the powder weight module.

[0351] In the present embodiment, since the powder weight module is detachably arranged, it has a mounted state arranged between the outlet end of the grinding module and the inlet end of the brewing module, and an unmounted state removed from between the outlet end of the grinding module and the inlet end of the brewing module. In step J1111, first, it can be automatically detected and confirmed whether the powder weight module is in the mounted state 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.

[0352] When it is confirmed that the powder weight module has been in the mounted state, it can be basically confirmed that the powder weight module has been mounted in place. Then it is needed to confirm whether the powder weight module has enabled the weighing mode. As known from the above, the powder weight module is optionally arranged with the weighing mode and the non-weighing mode, wherein when in the weighing mode, the powder weight module can measure the weight of the powder received by the transfer; when in the non-weighing mode, the powder weight module can receive the powder, or only as a communication pipeline for the powder to flow from the outlet end of the grinding module to the inlet end of the brewing module.

[0353] When it is confirmed that the powder weight module has enabled the weighing mode, further, the weighing value of the powder weight module can also be zeroed as described above. Then the weight of the powder received by the powder weight module can be measured in real time during the process that the grinding module continuously discharges the powder to the powder weight module. When the weight of the powder received by the powder weight module gradually increases to reach the powder weight reference value, the powder of the powder weight reference value is locked by controlling the grinding module to stop grinding and discharging the powder, and / or by controlling the powder weight module to stop receiving the powder, and the powder of the powder weight reference value is transferred to the brewing module for the brewing module to perform the brewing and extraction operation on the powder of the powder weight reference value.

[0354] Specifically, when the beverage preparation device is arranged with the liquid weight module, the liquid weight module is arranged at least at the outlet end of the brewing module, and can receive the beverage discharged outwardly via the brewing module. Specifically, the liquid weight module can be arranged externally on the outer wall of the housing, and correspondingly arranged at the beverage outlet. At this time, the above step J111 can be specifically:

[0355] Step J112: controlling the brewing module to start working and discharge the extracted beverage to the liquid weight module, and controlling the brewing module to stop working when the weight of the beverage received by the liquid weight module reaches the liquid weight reference value.

[0356] In the present embodiment, after the control device transfers the coffee powder reaching the powder weight reference value to the brewing module through the powder weight module, for example, the brewing module runs a conventional brewing process to prepare the coffee liquid and discharge the coffee liquid out through the beverage outlet. The control device controls the liquid weight module to start the weighing state in advance, timely receives the weight of the coffee liquid discharged out through the beverage outlet, and controls the brewing module to stop working when the weight of the coffee liquid reaches the liquid weight reference value, so that the coffee liquid is no longer discharged out through the beverage outlet.

[0357] Of course, before the control device controls the brewing module to start working and discharge the extracted beverage to the liquid weight module in step J112, the following steps are further included:

[0358] Step J1121: detecting whether the receiving container of the liquid weight module is installed in place, and zeroing the weighing value of the liquid weight module when installed in place.

[0359] In the present embodiment, the liquid weight module has an enabled state of moving to the lower side of the beverage outlet and a storage state of moving out of the lower side of the beverage outlet, and the liquid weight module is pre-designed to have a timing mode and a non-timing mode. When actually performing step J1121, it can be first detected whether the liquid weight module is currently in the enabled state; when the liquid weight module is in the enabled state, it is determined whether the liquid weight module is currently enabled in the timing mode; when the liquid weight module is enabled in the timing mode, the extraction time required from the time when the liquid weight module detects the liquid to the time when the weight of the beverage reaches the liquid weight reference value is obtained. The above confirmation process can be realized based on a pre-set sensor. The sensor can be a force sensor, a photoelectric sensor, an image recognition sensor, etc. arranged at the powder weight module.

[0360] When it is confirmed that the liquid weight module has been installed in place, further, the weighing value of the liquid weight module can be zeroed as described above. Then, during the process of continuously discharging the beverage to the liquid weight module at the beverage outlet, the weight of the beverage received by the liquid weight module can be measured in real time. When the weight of the beverage received by the liquid weight module gradually increases to reach the liquid weight reference value, the extraction time corresponding to the beverage of the liquid weight reference value is locked by controlling the brewing module to stop grinding the powder and / or by controlling the liquid weight module to stop receiving the beverage, etc.

[0361] Specifically, the above step of obtaining the actual extraction time specifically includes:

[0362] Step D100: recording a first time point when the liquid weight module receives the first drop of beverage discharged out through the beverage outlet;

[0363] Step D200: stopping the discharging when the weight of the beverage received by the liquid weight module reaches the liquid weight reference value, and recording a second time point;

[0364] Step D300: calculate the duration between the first time point and the second time point as the actual extraction duration.

[0365] In the present embodiment, when the first drop of coffee liquid is discharged outwards from the beverage outlet and accepted 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 outwards from the beverage outlet and accepted 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 liquid weight reference value, i.e., substantially when the last drop of coffee liquid is discharged outwards from the beverage outlet and accepted 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 the actual extraction duration.

[0366] It should be noted that the actual extraction duration obtained by the above-mentioned method does not include the pre-soaking time and the water stop time after pre-soaking, because the liquid weight module cannot measure the parameters of the pre-soaking time and the water stop time after pre-soaking. Of course, in order to achieve the same effect, the pre-soaking time and the water stop time after pre-soaking are also included in the actual extraction duration by using other timing devices or flow meter devices, so as to control the overall brewing time. This can also be another embodiment of the present application for measuring the extraction duration. When the brewing module includes a water pump as described above, the start time of the water pump is used to calculate the actual extraction duration.

[0367] As described above in detail, the water pump can selectively run the pre-soaking program and the extraction program, and the water stop time after pre-soaking is selectively arranged between the pre-soaking program and the extraction program. At this time, when the actual extraction duration is calculated by determining the start and stop time of the water pump, the actual extraction duration can include or not include the running time of the pre-soaking program and the water stop time after pre-soaking. Therefore, when the self-selected value of the same to-be-calibrated parameter is calibrated in each operation of the beverage preparation mode, the running time of the pre-soaking program and the water stop time after pre-soaking need to be consistently included or not included, so as to ensure the accuracy of the debugging operation.

[0368] Based on one or more embodiments of the above-mentioned step J100, step J200 is then executed: when the obtained quality state of the beverage does not meet the preset quality requirement, the next self-selected value of the to-be-calibrated parameter input by the user through the input device is re-acquired, and the beverage preparation mode is re-run according to the re-acquired self-selected value, until the re-obtained quality state of the beverage meets the preset quality requirement, and the current corresponding self-selected value is stored as the reference value of the to-be-calibrated parameter.

[0369] In the embodiment, when the system runs the beverage preparation mode according to the first self-selected value of the to-be-calibrated parameter input for the first time, and a beverage is prepared, the quality state of the beverage is obtained, and the quality state is compared with the preset quality requirement.

[0370] The specific definition of the quality state of the beverage is not limited, and can be defined as, for example, taste, flavor, color, concentration, quality, etc. of the beverage according to actual needs. The measurement method of the quality state is not limited, and can be determined by, but not limited to, user tasting or related sensor measurement, etc.

[0371] The preset quality requirement can be input in advance through the input device, or can be determined by the system calling the pre-stored data. The preset quality requirement can be related to the type of coffee beverage, etc.

[0372] When the quality state of the beverage meets the preset quality requirement, it means that all the operating parameters in the beverage preparation mode of the current run are appropriate, and the self-selected value of the to-be-calibrated parameter according to which the beverage preparation mode of the current run is run is also appropriate, which can be stored as the reference value of the to-be-calibrated parameter.

[0373] When the quality state of the beverage does not meet the preset quality requirement, it means that there is an error in the operating parameters in the beverage preparation mode of the current run. Since the reference value of the reference parameter is basically appropriate by default, it is inferred that the self-selected value of the to-be-calibrated parameter according to which the beverage preparation mode of the current run is run has an error. At this time, the user needs to be prompted to input another self-selected value of the same to-be-calibrated parameter through the input device, and the beverage preparation mode is run again according to the re-input self-selected value to obtain a new beverage, and the quality state of the beverage is detected and compared again……Such repeated operations are repeated until the quality state of the re-obtained beverage meets the preset quality requirement, and the self-selected value of the corresponding to-be-calibrated parameter is determined as the reference value as described above.

[0374] The reference value of the to-be-calibrated parameter can be selectively stored in the beverage cooking device, the control device of the beverage cooking device, and / or a mobile terminal in communication connection with the control device according to actual needs.

[0375] In addition, based on any of the above embodiments, in a further scheme, when the grinding module includes a cutter disc with adjustable grinding gap, the above beverage preparation mode of one-time or repeated run further includes:

[0376] Step C100: When the weight of the powder reaches the powder weight reference value, the weight of the beverage reaches the liquid weight reference value, and the actual extraction time is different from the extraction time self-selected value, the cutter disc grinding gap is adjusted, and the beverage preparation mode is re-run until the actual extraction time is the same as the extraction time self-selected value.

[0377] In the present embodiment, the weight value of the powder reaches the powder weight reference value, and the weight of the beverage reaches the liquid weight reference value, but the actual extraction duration is different from the input extraction duration self-selected value, which indicates that the abnormality of the grinder disc grinding gap may occur. At this time, the grinder disc grinding gap needs to be adjusted first. When the grinder disc grinding gap is adjusted to the right position, the weight value of the powder reaches the powder weight reference value, the weight of the beverage reaches the liquid weight reference value, and the actual extraction duration reaches the input extraction duration self-selected value, the subsequent operation of step J200 is continued.

[0378] It can be understood that when the actual extraction duration and the extraction duration self-selected value are known, the size relationship between the two may be as follows:

[0379] The actual extraction duration is approximately the same as the extraction duration self-selected value (within the deviation range of the extraction duration self-selected value). That is, the current running condition of the grinding module basically meets the preset, the grinder disc gap is kept in the appropriate range, and the present situation can be maintained without adjusting the grinder disc gap.

[0380] The actual extraction duration is different from the extraction duration self-selected value, and the actual extraction duration is greater than the extraction duration self-selected value. The actual extraction duration is different from the extraction duration self-selected value, which indicates that the current running condition of the grinding module is abnormal. Since no other condition abnormal parameter value is added, the finer the ground particles of the coffee powder, the more difficult it is to form a gap for water to flow through after the coffee powder is pressed into a powder cake, resulting in a slower extraction speed and an extended extraction duration. Therefore, when the actual extraction duration is greater than the extraction duration self-selected value, it indicates that the coffee powder currently ground by the grinding module is too fine, and the grinder disc gap needs to be appropriately increased.

[0381] The actual extraction duration is different from the extraction duration self-selected value, and the actual extraction duration is less than the extraction duration self-selected value. As described above, the actual extraction duration is different from the extraction duration self-selected value, which indicates that the current running condition of the grinding module is abnormal. Since no other condition abnormal parameter value is added, the coarser the ground particles of the coffee powder, the easier it is to form a gap for water to flow through after the coffee powder is pressed into a powder cake, resulting in a faster extraction speed and a shortened extraction duration. Therefore, when the actual extraction duration is less than the extraction duration self-selected value, it indicates that the coffee powder currently ground by the grinding module is too coarse, and the grinder disc gap needs to be appropriately reduced.

[0382] In view of the above, when the tool disc gap is abnormally large or small, in order to better adjust the tool disc gap to the right position, the specific adjustment method can include: when the actual extraction time length and the extraction time length self-selected value are different, calculating the current extraction time difference between the actual extraction time length and the extraction time length self-selected value; obtaining preset mapping associated data of the extraction time difference and the adjustment amount of the tool disc gap, and obtaining the target adjustment amount of the tool disc gap according to the mapping associated data and the current extraction time difference; and adjusting the tool disc gap according to the target adjustment amount.

[0383] In the embodiment, the whole machine is pre-stored with mapping associated data of the extraction time difference and the adjustment amount of the tool disc gap. When any one of the extraction time difference and the adjustment amount of the tool disc gap is known, the other one can be accurately and uniquely obtained through the mapping associated data. The specific form of the mapping associated data is not limited, which can be a function relationship, a point graph or a line graph, or a table integrated with a large amount of required data, so that the steps of repeatedly adjusting the tool disc gap can be reduced as much as possible according to the mapping associated data.

[0384] The obtaining method of the mapping associated data is not limited, which can be experience data obtained by recording user experience, experimental data obtained by a large number of experiments in advance, or fitting data obtained by simulation, etc. The mapping associated data is stored in the memory 150 of the control device 100, and can be called out and compared when needed.

[0385] Therefore, first, the step of calculating the current extraction time difference between the actual extraction time length and the extraction time length self-selected value in step J310 is performed. When the current extraction time difference is determined, the target adjustment amount of the tool disc gap associated with the current extraction time difference can be obtained by comparing the mapping associated data. Finally, the current gap value of the tool disc is obtained, and the gap is adjusted according to the target adjustment amount based on the current gap value, so that the tool disc gap can be adjusted to the right position.

[0386] In the technical scheme provided in the present application, during the preparation of the beverage, the correlation between the tool disc gap and the extraction time length is high when the actual powder weight is equivalent to the powder weight reference value and the actual liquid weight is equivalent to the liquid weight reference value, so by comparing the actual extraction time length with the extraction time length self-selected value, the adjustment of the tool disc gap can be directly determined according to the comparison result, the adjustment process is relatively simpler, and the reliability is higher.

[0387] Further, after the step C100 of determining that the actual extraction time length is approximately equal to the extraction time length self-selected value, it is indicated that the current burr gap meets the requirements. Further, in an embodiment, the following operations can be further performed: when the actual extraction time length and the extraction time length self-selected value are equal, the theoretical grinding time length and the actual grinding time length required to reach the powder weight reference value are obtained; the grinding efficiency is calculated according to the theoretical grinding time length and the actual grinding time length; and when the grinding efficiency is lower than a preset efficiency threshold, a prompt information of replacing the burr is sent.

[0388] In the embodiment, when the actual extraction time length and the extraction time length self-selected value are equal, the beverage preparation mode is re-run, and the actual grinding time length required to reach the powder weight reference value is recorded during the grinding of the coffee beans by the grinding module. Then, the theoretical grinding time length associated with the powder weight reference value is queried. According to the actual grinding time length and the theoretical grinding time length, the grinding efficiency is calculated. When the grinding efficiency is lower than a preset efficiency threshold, that is, the grinding efficiency is abnormal and cannot meet the requirements, the burr may be excessively worn and cannot be used continuously, and the burr needs to be replaced. At this time, the control device 100 sends a prompt information of replacing the burr. The prompt information can be displayed in any suitable manner. For example, when the shell is externally provided with a display and control module, 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 sent by a warning light, a prompt sound sent by a buzzer, a message push received by a mobile terminal in communication connection with the control device 100, etc.

[0389] Further, after the step of determining that the actual extraction time length is approximately equal to the extraction time length self-selected value, the following operations can be further performed:

[0390] The position information and / or the grinding gap of the current burr are obtained and stored as the reference value of the burr.

[0391] In the embodiment, as known from the above, it is determined that the actual extraction time length is approximately equal to the extraction time length self-selected value, which indicates that the current burr gap meets the requirements. At this time, the current burr parameters can be stored as the reference value of the burr. The burr parameters can be, but are not limited to, the position information of the burr, the grinding gap, etc. So that the reference value of the burr parameters can be directly called next time, and it is ensured that the above-mentioned various operating parameters meet the requirements.

[0392] Similarly, the reference value of the burr can be selectively stored in the beverage preparation device, the control device of the beverage preparation device, and / or a mobile terminal in communication connection with the control device.

[0393] In addition, in view of the above, before the step of instructing adjustment of the cutter head grinding gap, further comprising:

[0394] The adjustment range of the cutter head grinding gap is divided into multiple adjustment levels, and the unit adjustment amount of each adjustment level is not greater than 0.01 mm.

[0395] Specifically, the adjustment levels can be from -50 to 50, a total of 100, each with a difference of 0.01 mm (the number of levels can be set by selection, and does not necessarily have to be constant), or can be set to display the actual gap value in real time.

[0396] And after the step of instructing adjustment of the cutter head grinding gap, further comprising:

[0397] When the actual adjustment amount of the cutter head grinding gap exceeds 20 adjustment levels, a cutter head replacement prompt is issued.

[0398] In this embodiment, if the single or cumulative adjustment amount of the cutter head grinding gap reaches or exceeds 20 adjustment levels, i.e., 20 levels, it indicates that the cutter head is abnormal and needs to be replaced, prompting the user.

[0399] It should be noted that the calibration method of the beverage preparation device described above is used in a fully automatic coffee machine, or the debugging method of the beverage preparation device combined with the bean grinder 200 and the brewing machine 300 is named as CLS (Closed-Loop System) closed-loop control system technology, which is used for testing and adjusting the beverage preparation device in real time and automatically, and can realize one-key calibration to meet the quality control of the device for each cup of beverage in long-term and high-frequency use.

[0400] The CLS related scheme can be specifically referred to the first application example, and will not be described in detail here.

[0401] Fourth application example:

[0402] In this design, the control method of the beverage preparation device is specifically a liquid weight measurement method of the beverage preparation device. Please refer to FIG. 6, the liquid weight measurement method of the beverage preparation device includes:

[0403] Step E100: When receiving a preset instruction, running a beverage preparation mode according to the preset instruction;

[0404] In the embodiment, the preset instruction can be triggered by the user based on the input module, for example, as described above. At this time, the input module can be manually input by the user through, for example, a keyboard, a button, voice recognition, motion recognition, etc. Of course, the preset instruction can also be triggered automatically by the control device. At this time, the control device can be precompiled according to actual needs, and then triggered individually according to time, or linked with other working modes of the beverage preparation equipment for linkage triggering, etc. Specifically, it can be, but the beverage preparation equipment is triggered when it is started, and is automatically triggered after the beverage preparation equipment runs for a period of time or at a certain frequency, etc.

[0405] The type of preset instruction can be various, and the beverage preparation mode needs to be linked to run. Among them, the beverage preparation mode is the process of obtaining powder material to extract a cup of beverage, for example, it can be the process of directly obtaining coffee powder and transferring it to the brewing module for brewing and extraction; it can also be the process of directly obtaining coffee beans, grinding the coffee powder through the grinding module, and then transferring the coffee powder to the brewing module for brewing and extraction. Therefore, in actual application, the preset instruction can be, but is not limited to, various parameter debugging instructions or calibration instructions, working instructions for preparing a single beverage, seasoning instructions for preparing blended beverages, etc.

[0406] Step E200: control the liquid weight module to enable the function mode associated with the preset instruction;

[0407] In the embodiment, it should be noted that the order of steps E200 and E100 is not limited. According to actual needs, the beverage preparation mode can be run and step E200 can be executed after receiving the preset instruction in step E100. Among them, taking the beverage preparation equipment which further includes a grinding module and a powder weight module as an example, the process of running the beverage preparation mode can include the following steps respectively:

[0408] Step E110: control the grinding module to start grinding and transfer the powder to the powder weight module, and control the grinding module to stop working when the weight of the powder received by the powder weight module reaches the preset powder weight.

[0409] The control device 100 first controls the grinding module to start running, and starts the powder weight module in the weighing mode at the same time, in advance or after a certain time delay when the grinding module starts running. In this way, when the coffee beans are ground into powder by the grinding module and discharged outward through the outlet end, 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 communication between the grinding module and the powder weight module is immediately cut off, and / or the grinding module is immediately controlled to stop working, to avoid the powder weight module continuously receiving materials, resulting in overloading of the coffee powder.

[0410] Before the step of "controlling the grinding module to start grinding and to transfer the ground coffee powder to the powder weight module" in step E110, the following steps can also be included:

[0411] Step E111: detecting whether the powder weight module is currently installed between the outlet end of the grinding module and the inlet end of the brewing module;

[0412] Step E112: detecting whether the powder weight module is enabled in the weighing mode, when the powder weight module is currently installed between the outlet end of the grinding module and the inlet end of the brewing module; and,

[0413] Step E113: re-executing the step of "controlling the grinding module to start grinding and to transfer the ground coffee powder to the powder weight module", when it is confirmed that the powder weight module is enabled in the weighing mode.

[0414] In the present embodiment, the steps E111 to E112 need to be executed and completed before the outlet end of the grinding module starts to discharge the ground coffee powder, i.e. the grinding module starts to transfer the ground coffee powder to the powder weight module.

[0415] Since the powder weight module is detachably installed, it has an installed state of being installed between the outlet end of the grinding module and the inlet end of the brewing module, and an uninstalled state of being removed from between the outlet end of the grinding module and the inlet end of the brewing module. In step E111, first, it can be automatically detected and confirmed whether the powder weight module is installed in the machine housing and installed in place in the machine housing based on a preset sensor. If the powder weight module has been installed in the machine housing, but is not installed in place in the machine housing, or there is an abnormality in the installation direction, etc., it means that it is not installed in place in the machine housing. The sensor can be a force sensor, a photoelectric sensor, an image recognition sensor, etc. arranged at the powder weight module.

[0416] When it is confirmed that the powder weight module has been installed in the machine housing and installed in place in the machine housing, it is necessary to confirm whether the powder weight module is enabled in the weighing mode. As known from the above, the powder weight module can be optionally provided with a weighing mode and a non-weighing mode. When in the weighing mode, the powder weight module can measure the weight of the transferred powder; when in the non-weighing mode, the powder weight module can receive the powder, or only serve as a communication pipeline for the powder to flow from the outlet end of the grinding module to the inlet end of the brewing module.

[0417] 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 first zeroed as described above. Then, the weight of the powder received by the powder weight module can be measured in real time during the process that the grinding module continuously discharges powder to the powder weight module, forming the actual powder weight. When the actual powder weight of the powder received by the powder weight module gradually increases to reach the preset powder weight value, the preset powder weight of the powder 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 preset powder weight of the powder is transferred to the brewing module for the brewing module to perform the brewing and extraction operation on the preset powder weight of the powder.

[0418] Step E120: control the brewing module to start working and discharge the extracted beverage to the liquid weight module, and control the brewing module to stop working when the liquid weight of the beverage received by the liquid weight module reaches the preset liquid weight.

[0419] In this embodiment, for example, when the powder weight module has already received the powder of the preset powder weight in place, the brewing module is controlled to start running at the same time, before or after a certain time delay after the powder is transferred from the powder weight module to the brewing module. After the above-mentioned pressing into a cake, wetting and other extraction operations, the beverage prepared by the brewing module is discharged outwardly through the beverage outlet, received by the liquid weight module and weighed.

[0420] Before the step of discharging the beverage outwardly through the beverage outlet, it further includes:

[0421] Step E121: detecting whether the liquid weight module is currently in an enabled state;

[0422] Step E122: determining whether to enable the weighing mode and the timing mode when the liquid weight module is in the enabled state; and,

[0423] Step E123: when the liquid weight module enables the weighing mode and the timing mode, obtaining the actual extraction time required from when the liquid weight module detects the presence of liquid weight to when the actual liquid weight reaches the preset liquid weight.

[0424] In this embodiment, 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 the disabled state, for example, the receiving table is flipped from one side to close to the front panel of the machine shell, which does not hinder the normal liquid discharge of the beverage outlet, and helps to simplify the space occupation of the receiving table. In step E121, it is first necessary to confirm whether the liquid weight module is in the enabled state. Similarly, the confirmation process can be realized based on a preset sensor. The sensor can be a force sensor, a photoelectric sensor, an image recognition sensor, etc. arranged at the powder weight module.

[0425] For the actual extraction duration, the detection can be based on the timer of the peripheral device. In order to make the detection result of the actual extraction duration more accurate, in the 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. Thus, in step E122, it is first determined whether the weighing mode and the timing mode of the liquid weight module are enabled. The weighing mode of the liquid weight module is basically required to be started, but the timing mode can be selectively enabled.

[0426] When the liquid weight module is in the enabled state and the timing mode is enabled, the liquid weight module starts to weigh the coffee liquid in real time and count the time until the actual liquid weight of the coffee liquid reaches the preset liquid weight, and the counting is stopped.

[0427] For example, in a specific application, if the following steps are performed, the weighing mode and the timing mode of the liquid weight module need to be enabled:

[0428] Step E131: When the liquid weight module receives the first drop of beverage discharged outward through the beverage outlet, a first time point is recorded;

[0429] Step E132: When the weight of the beverage received by the liquid weight module reaches the preset liquid weight, the liquid discharge is stopped and a second time point is recorded;

[0430] Step E133: The duration between the first time point and the second time point is calculated as the extraction duration.

[0431] In the embodiment, when the first drop of coffee liquid is discharged outward 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. When the coffee liquid continues to be discharged outward 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, i.e. when the last drop of coffee liquid is discharged outward 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 the extraction duration (which can be the actual extraction duration).

[0432] More specifically, the weighing mode can also be divided into single weighing mode and multiple continuous weighing mode.

[0433] The single weighing mode means that only a single weighing is automatically performed when it is enabled. When the single weighing operation is completed, the weighing value of the liquid weight module can be directly reset to zero, or the weighing value is not immediately reset to zero, but subsequent changes in the weighing value are not recorded or stored as valid weighing values. It is suitable for responding to, for example, a single beverage work instruction.

[0434] The multiple consecutive weighing mode, when enabled, can automatically perform consecutive weighing for a preset number of times. The individual weighing value of each weighing and the cumulative weighing value can be recorded or stored. The multiple consecutive weighing mode is suitable for responding to, for example, a flavoring instruction of a blended beverage.

[0435] In addition, it needs to be explained that the above-mentioned liquid weight module can be specifically arranged to reciprocally move between the beverage outlet and the material output pipeline. Based on this, in the above-mentioned step E121, it can further specifically include:

[0436] Detecting whether the current position of the liquid weight module is accurate and in an enabled state;

[0437] The control device 100 can previously position the preset position below the beverage outlet and the preset position below the material output pipeline, for example, give specific coordinate values in a preset coordinate system. Then when the liquid weight module needs to be moved, the liquid weight module is moved to the corresponding coordinate value, and after confirming the accurate position, it is further confirmed whether the liquid weight module is currently in an enabled state.

[0438] Then, step E300: before receiving the beverage prepared by the beverage preparation mode, control the weighing value of the liquid weight module to zero.

[0439] In the embodiment, after the liquid weight module is in an enabled state and at least the weighing mode is enabled, the weighing value of the liquid weight module needs to be zeroed as described above. The operation of zeroing the weighing value needs to be performed before the brewing module prepares the beverage and discharges it outward through the beverage outlet. Specifically, it can be performed before, during, or after the beverage preparation mode is run, and the beverage outlet is closed by the valve structure. After the weighing value of the liquid weight module is zeroed, it indicates that the preparation for receiving and measuring the weight of the next beverage is completed, so that the subsequent gradual change of the weighing value of the liquid weight module is basically caused by the beverage received, which helps to improve the accuracy of the measurement value.

[0440] Specifically, step E300 can include:

[0441] Step E310: before receiving the beverage prepared by the beverage preparation mode, judging whether the liquid weight module is installed in place;

[0442] Step E320: if yes, control the weighing value of the liquid weight module to zero.

[0443] In view of the above, the step of confirming whether the liquid weight module is installed in place can be performed in the first confirmation in step E200, and / or can also be performed in the first confirmation or re-confirmation in step E310, to exclude the case that the measured weight value of the liquid weight module is abnormal due to improper installation of the liquid weight module.

[0444] The liquid weight module installed in place includes that the liquid weight module is installed to the correct position, such as installed to the beverage outlet or the material output pipeline; also includes that the liquid weight module is in an enabled state, such as the container of the liquid weight module has been stably placed directly below the beverage outlet or the material output pipeline; also includes that the liquid weight module enables the corresponding function mode, such as the weighing mode and the timing mode have been enabled.

[0445] When it is confirmed that the liquid weight module has been installed in place as described above, the next step of "controlling the weighing value of the liquid weight module to be zero" can be performed. At this time, the operation of "controlling the weighing value of the liquid weight module to be zero" can specifically include:

[0446] Step E321: judging whether the weighing value of the liquid weight module changes;

[0447] Step E322: if yes, controlling the weighing value of the liquid weight module to be zero.

[0448] In the embodiment, when the liquid weight module is in an enabled state, and the weighing mode and the timing mode are enabled, if the weighing value changes before the beverage is received, the weighing value change can be invalid, and the weighing value can be directly zeroed.

[0449] However, specifically, step E322 can be subdivided into:

[0450] Step E3221: if yes, and the weighing value of the liquid weight module increases, controlling the weighing value of the liquid weight module to be zero.

[0451] If the weighing value of the liquid weight module increases, that is, some objects are received on the weighing device of the liquid weight module, the weighing value of the liquid weight module can be directly zeroed.

[0452] Or the increment of the weighing value can be further subdivided:

[0453] If the increment of the weighing value of the liquid weight module does not exceed the preset increment threshold, it indicates that it is within the normal range, and the weighing value of the liquid weight module can be controlled to be zero. At this time, the increment of the weighing value of the liquid weight module can be due to the placement of the container on the liquid weight module, or can be due to other reasons, as long as it does not exceed the range of the liquid weight module, that is, it does not affect the receiving and weighing of the beverage, and can be directly zeroed.

[0454] But if the increase of the weighing value of the liquid weight module exceeds the preset increase threshold, it indicates that an abnormality occurs, for example, the range of the liquid weight module is exceeded, which will cause the liquid weight module to be unable to accurately measure the weight of the beverage. At this time, a prompt of the weighing abnormality of the liquid weight module can be issued to prompt the user to handle the abnormality immediately.

[0455] Of course, if the weighing value of the liquid weight module decreases, regardless of the amount of decrease in the weighing value, it can be determined that an abnormality occurs in the weighing value of the liquid weight module, and a prompt of the weighing abnormality of the liquid weight module can be directly issued.

[0456] It should be noted that the form of the prompt issued by the control device can be specifically set according to actual needs. The prompts issued due to various abnormalities can be the same or can be set to be different one by one corresponding to various abnormal conditions, so that the user can directly know the specific abnormal condition according to the prompt form.

[0457] In addition, as can be seen from the above, it can be necessary to repeatedly run the beverage preparation mode to separately measure the weights of the beverages obtained by multiple preparations in response to a certain preset instruction.

[0458] Based on this, in an embodiment, the liquid weight measurement method of the beverage cooking device further includes:

[0459] Step X100: When the received preset instruction is a beverage blending instruction and the beverage preparation mode is run according to the beverage blending instruction, obtaining preset blending information of the to-be-blended materials;

[0460] Step X200: Controlling the liquid weight module to enable a function mode associated with the beverage blending instruction;

[0461] Step X300: Before receiving the first to-be-blended material, controlling the weighing value of the liquid weight module to be zero, and controlling the liquid weight module to enable the continuous weighing mode according to the preset blending information.

[0462] In this embodiment, when the preset instruction is a beverage blending instruction, it indicates that the final beverage is composed of at least two to-be-blended materials, and one of the to-be-blended materials is a beverage (for example, coffee liquid) prepared by running the beverage preparation mode. Therefore, first, the preset blending information of the to-be-blended materials is obtained while, before, or after a certain time period after running the beverage preparation mode. The preset blending information can include, but is not limited to, the number of the to-be-blended materials, the output order of the to-be-blended materials, and a preset weight value of each to-be-blended material.

[0463] According to actual needs, after confirming that the liquid weight module is installed in place, in an enabled state, and the related functions such as the continuous weighing mode and the timing mode are enabled, the various materials to be blended can be sequentially received according to the output order of the materials to be blended, and the weights of the various materials to be blended are measured, so that the weights of the various materials to be blended in the final blended beverage meet the requirements.

[0464] Of course, in another embodiment, the liquid weight measurement method of the beverage preparation device further comprises:

[0465] When the beverage preparation mode is repeatedly run at least twice according to the same preset instruction, the liquid weight module is controlled to maintain the same function mode, and the weighing value of the liquid weight module is controlled to be zeroed before each time the prepared beverage is received again.

[0466] In this embodiment, when responding to, for example, a debugging instruction or a calibration instruction, or continuously responding to a single beverage operation instruction multiple times, the beverage preparation mode also needs to be repeatedly run, and the state of the liquid weight module needs to be maintained to be basically fixed and unchanged to avoid deviations in the measurement data due to repeated movement and repeated calibration of the liquid weight module. In order to make the measurement value of each prepared beverage meet the requirements, the weighing value of the liquid weight module is zeroed after the weight measurement operation of the previous beverage ends and before the weight measurement operation of the next beverage starts.

[0467] In addition, the liquid weight measurement method of the beverage preparation device described above can be applied to any scene, for example, applied to the debugging method of the beverage preparation device described in the first application example. For details, please refer to the first application example section, which will not be described here.

[0468] Fifth application example:

[0469] In this design, the control method of the beverage preparation device is specifically a grinding gap adjustment method of the beverage preparation device. It should be noted that the beverage preparation device in this design can be the beverage preparation device described above, and further:

[0470] In order to be able to transfer the powder prepared by the grinding module to, for example, the brewing cylinder of the brewing module:

[0471] In one application, the beverage preparation device is configured to directly transfer the powder between the grinding module and the brewing module.

[0472] At this time, in an embodiment, the brewing cylinder is fixed relative to the grinding module, and the inlet end of the brewing cylinder and the outlet end of the grinding module are connected and disconnected. The connection and disconnection of the inlet end of the brewing cylinder and the outlet end of the grinding module can be, but is not limited to, achieved by, for example, a controllable valve structure, a controllable opening and closing structure, etc. The brewing cylinder and the grinding cylinder are kept connected to form a powder flow path from the grinding cylinder to the brewing cylinder. The above-mentioned valve structure, opening and closing structure, etc. are used to control the conduction and isolation of the powder flow path.

[0473] Alternatively, in another embodiment, at least one of the brewing cylinder and the grinding module is movably arranged relative to the other to have a powder receiving position where the inlet end of the brewing cylinder and the outlet end of the grinding module are in communication. Specifically, the grinding cylinder can be fixed relative to the machine housing, but the brewing cylinder can be movable relative to the machine housing and can be moved close to the grinding cylinder to the powder receiving position and moved away from the grinding cylinder to the brewing position. Alternatively, the brewing cylinder can be fixed relative to the machine housing, but the grinding cylinder can be movable relative to the machine housing and can be moved close to the brewing cylinder to the powder receiving position and moved away from the brewing cylinder to the grinding position. Of course, the grinding cylinder and the brewing cylinder can also move close to each other and move away from each other. It can be understood that when the grinding cylinder and the brewing cylinder move close to each other to the powder receiving position, a conduction powder flow path from the grinding cylinder to the brewing cylinder can be formed to allow powder transfer; when the grinding cylinder and the brewing cylinder move away from each other to the brewing position or the grinding position, the powder flow path cannot be formed and powder transfer cannot be achieved.

[0474] In an application, the beverage preparation device is configured to transfer the powder after the powder is directly transferred between the grinding module and the brewing module. Based on this, the beverage preparation device further comprises a transfer container, which forms an accommodation cavity, and the accommodation cavity is connected and disconnected to the outlet end of the grinding module and the inlet end of the brewing cylinder, respectively. As described above, the connection and disconnection can be achieved by, for example, a valve structure, an opening and closing structure, etc.

[0475] Specifically, in an embodiment, at least the outlet section of the grinding cylinder can constitute the transfer container. At this time, the grinding mechanism, for example, the cutter head, is mainly arranged at the inlet section of the grinding cylinder, and the powder is ground at the inlet section of the grinding cylinder. The powder can flow to the outlet section of the grinding cylinder, i.e. the transfer container, to achieve the transfer and pre-acceptance of the powder in the transfer container. When the powder in the grinding cylinder needs to be transferred to the brewing cylinder, the rear section of the grinding cylinder can be connected to the inlet end of the brewing cylinder.

[0476] And / or specifically in an embodiment, at least the inlet section of the brewing cylinder can be configured as the transfer container. At this time, the normal operation of the grinding cylinder grinds the bean material into powder material, and the powder material can be transferred to the inlet section of the brewing cylinder, i.e., the transfer container, in real time or as needed, to achieve the pre-acceptance of the powder material in the transfer container. The brewing mechanism is mainly arranged at the outlet section of the brewing cylinder, so when the brewing mechanism needs to be operated, the powder material at the inlet section of the brewing cylinder, i.e., the transfer container, can be transferred to the outlet section of the brewing cylinder.

[0477] And / or specifically in an embodiment, the transfer container is a structure separately arranged independently of the grinding module and the brewing module. At this time, the transfer container can be connected to the grinding cylinder and the brewing cylinder as needed to achieve the pre-acceptance of the powder material in the transfer container and to achieve the purpose of transferring the powder material to the brewing cylinder through the transfer container. Based on this, further, the transfer container can be arranged to be fixed in position relative to the grinding module and the brewing cylinder; the receiving cavity is connected to the outlet end of the grinding module and the inlet end of the brewing cylinder through the opening and closing member to be connected and disconnected. That is, the transfer container remains connected between the grinding cylinder and the brewing cylinder to form a powder material flow path, but the conduction or isolation of the powder material flow path can be controlled and achieved through valve body structures, opening and closing structures, etc. Or further, the transfer container can be arranged to be reciprocally arranged between the grinding module and the brewing cylinder, and when the transfer container is arranged close to the grinding module, the receiving cavity is connected to the outlet end of the grinding module; and when the transfer container is arranged close to the brewing cylinder, the receiving cavity is connected to the inlet end of the brewing cylinder. That is, when the transfer container is arranged close to the grinding cylinder, the powder material formed by the grinding cylinder can be pre-accepted; when the transfer container is arranged close to the brewing cylinder, the powder material pre-accepted by the transfer container can be transferred to the brewing cylinder.

[0478] There are various schemes for the transfer container, but in a specific application, the beverage preparation device further includes a powder weight module for measuring the weight of the powder material; the powder weight module is provided with a transfer container for receiving the powder material. The powder weight module is generally arranged at the outlet end of the grinding module and the inlet end of the brewing cylinder, and after weighing or weighing the powder material discharged outwardly by the grinding module, the powder material is transferred to the brewing cylinder as needed.

[0479] In view of the above, referring to FIG. 7, the grinding gap adjustment method of the beverage preparation device includes:

[0480] Step U100: control the grinding module to start running;

[0481] In this embodiment, the grinding module can be started to run under the triggering of a related instruction. For example, a debugging instruction for debugging any disc parameter of the grinding module, a debugging instruction for debugging the parameters of other modules of the beverage preparation device, a working instruction in normal work, etc. When the instruction is triggered, the control device 100 controls the grinding module to start running to grind the bean material into powder material.

[0482] In the process of starting the operation of the grinding module, the adjustment operation of the grinding gap of the cutter head can be performed directly in response to the initial instruction (for example, the initial instruction is the adjustment instruction) or in response to the adjustment instruction triggered by the user additionally. The adjustment operation of the grinding gap can be one-time adjustment to the position or repeated adjustment to the position.

[0483] Step U200: In response to the adjustment of the grinding gap of the cutter head, the grinding module is controlled to continue to operate until the residual powder is exhausted.

[0484] In the embodiment, when the grinding gap changes, the powder formed by grinding before the adjustment of the grinding gap is the original particle size powder; and the powder formed by grinding after the adjustment of the grinding gap is the new particle size powder. The particle sizes of the original particle size powder and the new particle size powder are necessarily different, and if mixed, it is easy to adversely affect the quality of the beverage obtained by subsequent brewing and extraction based on the powder. Therefore, in the design, after confirming that the cutter head adjusts the grinding gap in response to the adjustment instruction, the grinding module is controlled to continue to operate, that is, the cutter head is controlled to continue to grind, so that the original particle size powder remaining between the two cutter heads is automatically exhausted by the grinding movement, and it is ensured that the original particle size powder remaining in the two cutter heads is exhausted. In this way, it is ensured that the grinding gap is adjusted, and the grinding module is started to operate again at the same time or after the adjustment, and the powder obtained by grinding between the two cutter heads is basically the new particle size powder.

[0485] As known from the above, when the grinding gap is adjusted in response to the adjustment instruction, it can be adjusted to the position by one-time adjustment; but more often, it needs to be adjusted to the position by multiple adjustments. At this time, the above step U200 specifically includes:

[0486] Step U210: Adjusting the grinding gap of the cutter head multiple times in response to the adjustment instruction.

[0487] Step U220: When the adjustment of the grinding gap meets the preset exhaust condition, the grinding module is controlled to continue to operate until the residual powder is exhausted.

[0488] In the embodiment, the grinding gap of the cutter head is continuously adjusted multiple times, and each adjustment of the grinding gap can be adjusted to be larger or smaller. At this time, the preset exhaust condition can be further input manually by the user based on the input module or preset by the precompiled program, so that after each adjustment of the grinding gap, the preset exhaust condition is compared and judged, so that when the preset exhaust condition is met, the grinding module is controlled to continue to operate until the residual powder is exhausted. In this way, the exhaust operation in the adjustment process of the grinding gap can be more flexible and adapted to specific application scenarios.

[0489] The setting scheme of the preset exhaust condition is not limited:

[0490] In an embodiment, the preset emptying condition is met when the number of times of adjustment of the grinding gap reaches a first number threshold. The first number threshold includes one or at least two. That is, the emptying operation can be performed once after each adjustment of the grinding gap, or the emptying operation can be performed once after every first number threshold of adjustments, so as to adjust the frequency of the emptying operation.

[0491] In an embodiment, the preset emptying condition is met when the adjustment quality of the grinding gap reaches a quality requirement. It can be understood that after the adjustment of the grinding gap, it is necessary to determine whether the current grinding gap is adjusted in place by manual measurement or by related modules. The reference scheme for whether the grinding gap is adjusted in place can be determined by visually observing the quality of the new particle size powder, or by extracting a cup of beverage to sense the quality of the beverage. If the adjustment quality corresponding to the adjustment in place of the grinding gap is the target adjustment quality. The quality requirement set for the preset emptying condition can be directly determined as the target adjustment quality, that is, when the grinding gap is completely adjusted in place, a unified emptying operation is performed. Or the quality requirement set for the preset emptying condition can be set as any degree of adjustment quality before the target adjustment quality is reached, for example, reaching 20% of the target adjustment quality, reaching 50% of the target adjustment quality, and the like.

[0492] In an embodiment, the preset emptying condition is met when the adjustment variable of the grinding gap reaches a variable threshold. It can be understood that when the adjustment variable of the grinding gap is relatively small, although there is still a difference between the new particle size powder and the original particle size powder, the difference between the two is relatively small, and the impact on the quality of the subsequent beverage is small, at this time, an emptying operation is not required. Conversely, when the adjustment variable of the grinding gap is relatively large, the difference between the new particle size powder and the original particle size powder is relatively large, and an emptying operation needs to be performed.

[0493] Step U300: transferring the emptied powder to the brewing cylinder, and controlling the brewing mechanism to extract the powder;

[0494] In the embodiment, when the grinding module continuously operates to empty the original particle size powder, in order to better achieve the processing of the emptied powder, the emptied powder can be transferred to the brewing cylinder for centralized processing.

[0495] There are various schemes for transferring the emptied powder to the brewing cylinder:

[0496] In view of the above, when the position of the brewing cylinder relative to the grinding module is fixed, and the inlet end of the brewing cylinder and the outlet end of the grinding module are connected in an on-off manner, step U300 includes:

[0497] Step U311: control the inlet end of the brewing cylinder and the outlet end of the grinding module to be in communication, so that the powder enters the brewing cylinder through the grinding module.

[0498] In this embodiment, the brewing cylinder and the grinding cylinder cannot be relatively moved, and the two maintain a connection relationship, and the powder flow path from the grinding cylinder to the brewing cylinder always exists. At this time, by controlling the valve structure, opening and closing structure, etc., the powder flow path is communicated, so that the purpose of transferring the empty powder to the brewing cylinder can be achieved; when the powder flow path is blocked, the empty powder cannot be transferred to the brewing cylinder.

[0499] Alternatively, when at least one of the brewing cylinder and the grinding module is movably arranged relative to the other to have a powder receiving position in which the inlet end of the brewing cylinder and the outlet end of the grinding module are in communication, step U300 comprises:

[0500] Step U312: control the brewing cylinder and the grinding module to move close to the powder receiving position, so that the powder enters the brewing cylinder through the grinding module.

[0501] In this embodiment, by controlling the grinding cylinder and the brewing cylinder to move close to the powder receiving position, a communicated powder flow path between the grinding cylinder and the brewing cylinder is formed, and the purpose of transferring the empty powder to the brewing cylinder is achieved; on the contrary, when the grinding cylinder and the brewing cylinder are controlled to move away from each other to the brewing position or the grinding position, the communicated powder flow path cannot be formed, and the empty powder cannot be transferred to the brewing cylinder.

[0502] Alternatively, when the beverage preparation device further comprises a transfer container, the transfer container is formed with a receiving cavity, and the receiving cavity is in communication with the outlet end of the grinding module and the inlet end of the brewing cylinder, step U300 comprises:

[0503] Step U313: control the receiving cavity and the outlet end of the grinding cavity to be in communication, and control the receiving cavity and the inlet end of the brewing cylinder to be in communication, so that the powder enters the brewing cylinder through the grinding module.

[0504] In this embodiment, whether the transfer container is fixed relative to the grinding cylinder and the brewing cylinder, so that the powder flow path from the grinding cylinder to the brewing cylinder through the transfer container always exists, or the transfer container is movable relative to the grinding cylinder and the brewing cylinder, and the powder flow path is formed during movement, the following can be achieved: by controlling the valve structure, opening and closing structure, etc. to communicate the flow path between the grinding cylinder and the transfer container, the purpose of transferring the empty powder to the transfer container and achieving the transfer and pre-receiving of the powder can be achieved; by controlling the valve structure, opening and closing structure, etc. to communicate the transfer container and the brewing cylinder, the purpose of transferring the pre-received powder to the brewing cylinder can be achieved.

[0505] Of course, the transfer container can also not be enabled with the transfer pre-accept function. As described above, when the complete communication between the grinding cylinder, the transfer container and the brewing cylinder is maintained, the transfer container is equivalent to a connecting pipeline that directly and real-timely transfers the emptied powder to the brewing cylinder.

[0506] Based on the above, it should be noted that when the transfer container is provided as described above and the transfer pre-accept function is enabled, the step U300 can further include:

[0507] Step U314: Control the communication between the outlet end of the grinding cavity and the receiving cavity, and control the isolation between the inlet end of the receiving cavity and the brewing cylinder.

[0508] Step U315: When the preset transfer condition is met, control the communication between the inlet end of the receiving cavity and the brewing cylinder, so that the powder enters the brewing cylinder through the grinding module.

[0509] In this embodiment, the transfer container can transfer a certain amount of powder discharged after one or more emptying operations. At this time, in order to avoid too much and too concentrated powder entering the brewing cylinder, the process of transferring the powder from the transfer container to the brewing cylinder can be preset with a transfer condition. As described above, the preset transfer condition can be manually input by the user based on the input module, or formed by a pre-compiled program.

[0510] There are many schemes for the preset transfer condition:

[0511] In an embodiment, the preset transfer condition is met when the emptying number of the grinding module reaches a second number threshold. The second number threshold includes one or at least two. That is, according to actual needs, after each emptying operation of the grinding module, a transfer operation can be directly performed once; or a transfer operation can be performed every second number threshold, so as to adjust the execution frequency of the powder transfer operation.

[0512] In an embodiment, the preset transfer condition is met when the emptying powder amount of the grinding module reaches a first powder amount threshold. It can be understood that since the powder amount of the powder pre-accepted by the transfer container is limited, and the powder amount of the powder accepted by the brewing cylinder is also limited. In addition, the extraction treatment of the powder by the brewing mechanism is also related to the powder amount of the powder in the brewing cylinder to a certain extent. Therefore, by limiting the emptying powder amount of the grinding module, the effect of the transfer and extraction treatment of the powder can be optimized to a certain extent.

[0513] In addition, there are many schemes for the extraction treatment of the powder by the brewing mechanism:

[0514] In an embodiment, when the brewing mechanism comprises the powder pressing module as described above, the powder pressing module comprises two piston members arranged in the brewing cylinder, at least one of the two piston members is movably arranged relative to the other one to have a powder pressing stroke in which the two piston members are close to each other and a releasing stroke in which the two piston members are away from each other, the step U300 comprises:

[0515] Step U321: controlling the two piston members to perform the powder pressing stroke to press the powder between the two piston members into a powder cake.

[0516] In the embodiment, by controlling the two piston members to perform the powder pressing stroke, the powder emptied and transferred into the brewing cylinder can be pressed into a powder cake, so that the powder in a loose state is prevented from flying everywhere, polluting or clogging the surrounding module.

[0517] At this time, further, if the powder pressing module has a first powder pressing stroke amount in response to the beverage preparation instruction and a second powder pressing stroke amount in the extraction process, the second powder pressing stroke amount is not greater than the first powder pressing stroke amount. That is, the powder pressing pressure of the two piston members on the powder during the extraction process can be appropriately reduced, and the extraction process has no specific requirements for the thickness of the powder cake pressed, etc., and only needs to ensure that the powder does not fly.

[0518] And / or in an embodiment, when the brewing mechanism comprises the water supply assembly as described above, the water supply assembly is used to access liquid into the brewing cylinder, the step U300 comprises:

[0519] Step U322: controlling the water supply assembly to access liquid into the brewing cylinder to wet the powder in the brewing cylinder.

[0520] In the embodiment, by controlling the water supply assembly to access liquid into the brewing cylinder, the powder in the brewing cylinder can be wetted, which also helps to prevent the powder in a loose state from flying everywhere, polluting or clogging the surrounding module.

[0521] At this time, further, if the water supply assembly has a first water supply amount in response to the beverage preparation instruction and a second water supply amount in the extraction process, the second water supply amount is not greater than the first water supply amount. That is, the amount of water accessed by the water supply assembly to the powder during the extraction process can be appropriately reduced, and the extraction process has no specific requirements for the wetting degree of the powder, etc., and only needs to ensure that the powder does not fly.

[0522] When the brewing mechanism simultaneously comprises the powder pressing module and the water supply assembly as described above, a wetted powder cake can be obtained after the extraction process, which helps to further enhance the concentration treatment effect on the powder and facilitates subsequent concentrated removal of the powder.

[0523] In addition, based on any of the above embodiments, the above step U30 can specifically comprise:

[0524] Step U310: transfer the emptied powder into the brewing cylinder, and when the preset processing condition is met, control the brewing mechanism to perform extraction processing on the powder.

[0525] It can be understood that, in order to avoid too frequent extraction processing on the powder, resulting in energy waste, the process of the brewing mechanism performing extraction processing on the powder can be preset with a processing condition. As described above, the preset processing condition can be manually input by the user based on the input module, or formed by a pre-compiled program, etc.

[0526] There are many schemes for the preset processing condition:

[0527] In an embodiment, the preset processing condition is met when the number of emptying operations of the grinding module reaches a third number threshold. The third number threshold includes one or at least two. That is, according to actual needs, after each emptying operation of the grinding module, a transfer operation and an extraction processing operation can be directly performed once; or after every third number threshold, a transfer operation and an extraction processing operation can be performed once or several times, to adjust the execution frequency of the powder extraction processing operation.

[0528] In an embodiment, the preset transfer condition is met when the emptying powder amount of the grinding module reaches a second powder amount threshold. It can be understood that, since the brewing mechanism needs to consume more power to perform extraction processing when the powder amount of the powder accumulated in the brewing cylinder is large, by limiting the emptying powder amount of the grinding module, the effect of extraction processing can be optimized to a certain extent.

[0529] Step U400: remove the powder residue formed after extraction processing from the brewing cylinder.

[0530] In this embodiment, there are many ways to remove the powder residue formed after extraction processing, for example, the brewing cylinder can be separately tilted, the powder residue in the brewing cylinder can be grabbed and dropped, etc. Alternatively, the removal of the powder residue can be combined with the cleaning process described below.

[0531] Step U500: clean the brewing cylinder.

[0532] In this embodiment, since the powder residue formed after extraction processing is removed from the brewing cylinder, the brewing cylinder will continue to be used for conventional beverage preparation, so the brewing cylinder needs to be cleaned in time.

[0533] Specifically, in an embodiment, when the brewing module includes a press-powder module as described above, at least one piston member can be controlled to move relative to the brewing cylinder to scrape the residual powder residue in the brewing cylinder out of the brewing cylinder, and in the process of the movement of the piston member, the outer peripheral side wall of the piston member slides against the inner cylinder wall of the brewing cylinder, which is sufficient to scrape the residual powder residue on the inner cylinder wall of the brewing cylinder out of the inlet end of the brewing cylinder. Then, the surface of the movable piston member is cleaned. Specifically, a residue scraping plate can be provided at the corresponding position of the brewing module, and the residue scraping plate is located at the inlet end of the brewing cylinder and has a transverse relative displacement with the movable piston member, and in the process of the relative displacement, the residual powder residue on the surface of the movable piston member is scraped out. Alternatively, the powder residue in the brewing cylinder and / or at the piston member can be cleaned by, for example, discharging liquid, high-temperature steam, etc.

[0534] Based on any of the above embodiments, it can be understood that the adjustment process of the cutter head grinding gap can be applied in any suitable scenario, for example, in the commissioning method of the beverage preparation device described in the first application example. For details, please refer to the first application example part, which will not be described here in detail.

[0535] Sixth application example:

[0536] In the design, the control method of the beverage preparation device is specifically a powder weighing calibration method of the beverage preparation device. According to the specific embodiments of the beverage preparation device described above, the beverage preparation device further includes an input module. At this time, according to actual needs, the input module can be used by the user to input a target powder weight value, each first weighing powder weight value, and / or each second weighing powder weight value (for details, please refer to the following text). The display and control module can display the target powder weight value, each first weighing powder weight value, and / or each second weighing powder weight value input by the user (for details, please refer to the following text). According to actual needs, the state of each bean bin, the state of the grinding module, the state of the powder weighing module, etc. can also be displayed.

[0537] In view of this, please refer to FIG. 8, the powder weighing calibration method of the beverage preparation device includes:

[0538] Step P100: Obtain a preset number of target powder weight values input by the user through the input module, and control the powder supply module to discharge in sequence according to each target powder weight value;

[0539] In this embodiment, when it is determined that the powder weighing module needs to be calibrated, the user can actively input a preset number of target powder weight values through the input module.

[0540] Among them, the preset number can be determined by the user actively inputting, that is, the number is confirmed by the user independently. Of course, the preset number can also be the default of the control device 100.

[0541] The preset number value also determines how many times the bean bin and grinding module need to discharge, how many first powder weight values the powder weight module needs to measure, and how many second powder weight values the external weighing device needs to measure, etc. To some extent, the more the preset number, the more the measurement data, and the more accurate the final calculation result. Therefore, in this embodiment, the preset number is set to no less than three. However, if the preset number is too large, it will increase the discharge burden of the bean bin and grinding module, the measurement burden of the powder weight module, the operation complexity of the entire calibration process, and the degree of consumption of the powder. Therefore, the preset number should not be set too large. For example, the control device 100 determines the preset number to be three according to the program in advance, and the preset number is basically unchangeable.

[0542] The target powder weight value is generally set within a reasonable range, for example, between 8g and 30g, and can be selected as 18g or 20g, etc.

[0543] Based on this, in an embodiment, the powder weighing calibration method of the beverage preparation device further comprises:

[0544] Step G600: When it is confirmed that the target powder weight value input by the user through the input module exceeds the preset powder weight threshold, it is determined that the input of the target powder weight value is invalid.

[0545] It can be understood that the control device 100 presets a powder weight threshold for the target powder weight value, which can be a numerical range with a powder weight minimum threshold and a powder weight maximum threshold. When the target powder weight value input by the user through the input module is less than the powder weight minimum threshold or greater than the powder weight maximum threshold, it is considered invalid. At this time, the target powder weight value input by the user that exceeds the powder weight threshold can be optionally not displayed.

[0546] When the preset number is multiple, according to actual needs, each target powder weight value can be set to be the same, that is, it can be input once, and the multiple preset areas all use the value input this time. For example, as shown in P1 area in FIG. 13, only one input box of the target powder weight value is provided, and the target powder weight values of the preset number are all the same by default. In this way, it is helpful to simplify the calibration process of the powder weight module and improve the calibration efficiency.

[0547] Of course, according to actual needs, the target powder weight values can also be set to be at least partially different. At this time, the input module can preset multiple input boxes for the target powder weight values for the user to input each target powder weight value one by one. Since the target powder weight values are different, the input order of each target powder weight value is also confirmed and recorded, and then the hopper and the grinding module are controlled to discharge the powder in sequence according to the target powder weight values, the powder weight module is controlled to measure in sequence according to the target powder weight values, and the external weighing device is controlled to measure in sequence according to the target powder weight values. And finally, according to actual needs, the first measured powder weight value and the second measured powder weight value are calculated in sequence. When at least part of the target powder weight values are different, the measurement ranges of the powder weight module can be calibrated purposefully, which helps to improve the calibration accuracy and comprehensiveness.

[0548] When the powder supply module is set to be multiple, for example, as shown in the P2 area of FIG. 13, the hopper and the grinding module are set to be multiple one by one, the step P100 can specifically include:

[0549] Step P110: selecting at least one powder supply module from the powder supply modules as a target powder supply module;

[0550] Step P120: controlling the target powder supply module to discharge in sequence according to the target powder weight values.

[0551] In this embodiment, as shown in the P2 area of FIG. 13, the beverage preparation device is preset with, for example, three sets of hopper and grinding module, and three buttons are reserved for the user to press and confirm. The three hoppers can store the same or different bean materials. According to actual needs, the user can select a powder supply module (for example, a target hopper) from each powder supply module (for example, a hopper) based on, for example, the variety of the bean material, the current storage amount of the bean material, the storage time of the bean material, the orientation of the hopper, etc. Subsequently, the powder weight module and the like can be discharged in sequence through the target powder supply module.

[0552] Of course, the target powder supply module can also be the system default, for example, in the pre-compiled program, the same powder supply module is fixedly selected as the target powder supply module.

[0553] Step P200: controlling the powder weight module to receive and weigh the powder to obtain a first measured powder weight value, and then transferring the powder to an external weighing device to obtain a second measured powder weight value when the powder supply module discharges each time;

[0554] In the present embodiment, since the powder supply module is to discharge powder in sequence, in order to make the first weighed powder weight value and the second weighed powder weight value of each group correspond to each other, when the powder supply module discharges powder, the powder is first received by the receiving container in the powder weight module, and then weighed by the weighing device to obtain and record the first weighed powder weight value. Then, the powder is transferred to the external weighing device for weighing to obtain and record the second weighed powder weight value.

[0555] The external weighing device can be any suitable weighing device that is different from the powder weight module. Generally, the external weighing device is independent of the beverage preparation device and is not integrated into the machine housing by the beverage preparation device. When needed, the external weighing device can be manually or automatically moved into the machine housing and to a position suitable for receiving the powder transferred from the powder weight module, such as below the receiving channel, to ensure that the powder is not lost during the transfer process.

[0556] Specifically, when the beverage preparation device includes a residue collection box as described above, the external weighing device can be moved to the powder falling area of the residue collection box to help accurately receive the powder transferred from the powder weight module.

[0557] At this time, step P200 can specifically include:

[0558] Step P210: when the powder supply module discharges powder, the opening and closing member is controlled to move to the closed position to receive the powder discharged outwardly by the powder supply module;

[0559] Step P220: the weighing device is controlled to start and weigh the received powder to obtain the first weighed powder weight value;

[0560] Step P230: the opening and closing member is controlled to move to the open position to transfer the powder in the receiving container to the external weighing device for weighing to obtain the second weighed powder weight value.

[0561] In the present embodiment, before the powder supply module discharges powder, specifically, for example, before the grinding module discharges powder, the powder weight module is controlled to be installed in place at the outlet end of the grinding module. The opening and closing member in the powder weight module is controlled to be in the closed position, the receiving channel is blocked, and a cavity for smoothly receiving powder is formed; the weighing device is enabled to start the weighing mode.

[0562] When the powder supply module completes the present discharge, the weighing device can measure the weight of the receiving container and the powder received therein as a whole to obtain the first weighed powder weight value.

[0563] Then, the opening and closing member is controlled to move to the open position, and the powder received in the receiving channel can be completely transferred to the external weighing device, for example, located at the powder falling area, under the action of gravity, and weighed by the external weighing device to obtain the second weighed powder weight value.

[0564] Of course, the external weighing device can also be directly arranged outside the machine shell, and then the powder in the powder weighing module is transferred outwards through a structure such as a pipeline, so as to facilitate the user to intuitively obtain the measurement value of the external weighing device.

[0565] It should be noted that during each discharge of the powder supply module, the powder discharged each time is weighed by the same external weighing device, and the external weighing device is not moved or pressed by external force during the weighing.

[0566] After the first and / or second powder weight values are obtained, they can be automatically transmitted to the control device 100 through wired or wireless transmission and displayed on the display and control module, such as the P3 and P4 areas shown in FIG. 13. Alternatively, when the first and / or second powder weight values are obtained, the user can record and input the data in the P3 and P4 areas shown in FIG. 13.

[0567] In addition, the powder weighing calibration method of the beverage preparation device further comprises:

[0568] Step G100: When the cancel instruction is received, the current state of the powder weighing module is obtained.

[0569] Step G200: When it is confirmed that the receiving container currently receives the powder, the opening and closing member is controlled to move to the open position to empty the powder in the receiving container, and it is determined that the current first weighing powder weight value is invalid.

[0570] It can be understood that the input module can be pre-provided with an area where the cancel instruction can be entered in the form of a button. When the cancel instruction is triggered, the control device 100 first obtains the current state of the powder weighing module. The current state of the powder weighing module can include that the first weighing operation has not started, between two adjacent weighing operations, in the process of any weighing operation, and all weighing operations have been completed.

[0571] When it is confirmed that the current state of the powder weighing module is, for example, in the process of any weighing operation, that is, the current opening and closing member is in the closed position and is still receiving or has completed the reception of the powder. Since the cancel instruction is triggered, the current weighing operation is interrupted, and the opening and closing member needs to be controlled to move to the open position to completely empty the powder received in the receiving channel, so as to avoid interference with the next weighing operation. Moreover, the control device 100 determines that the first weighing powder weight value obtained by the current weighing is invalid.

[0572] Of course, correspondingly, if the powder supply module has not completed the current discharge, the powder supply module also needs to be controlled to continue discharging until the powder is emptied, and then stopped running. If the powder supply module has completed the current discharge, the powder supply module is directly controlled to stop running.

[0573] When it is confirmed that the current state of the powder weighing module is, for example, that the first weighing operation has not yet started, between two adjacent weighing operations, all weighing operations have been completed, etc., that is, there is substantially no residual powder in the receiving channel, and it does not substantially affect any one weighing operation, the powder weighing module can be directly controlled to pause. Correspondingly, the powder supply module can also be controlled to stop running.

[0574] In addition, the powder weighing calibration method of the beverage preparation device further comprises:

[0575] Step G300: Before the powder weighing module completes the weighing operation on the powder, the input function of the input module related to the first measured powder weight value is disabled.

[0576] It can be understood that before the powder weighing module completes a single weighing operation, the input module cannot input the first measured powder weight value of this time. Or before the powder weighing module completes all weighing operations, the input module cannot input any first measured powder weight value. Avoiding user misoperation affecting the formation of subsequent conclusions.

[0577] Similarly, the powder weighing calibration method of the beverage preparation device further comprises:

[0578] Step G400: Before the external weighing device completes the weighing operation on the powder, the input function of the input module related to the second measured powder weight value is disabled.

[0579] It can be understood that before the external weighing device completes a single weighing operation, the input module cannot input the second measured powder weight value of this time. Or before the external weighing device completes all weighing operations, the input module cannot input any second measured powder weight value. Avoiding user misoperation affecting the formation of subsequent conclusions.

[0580] Step P300: According to each first measured powder weight value and each second measured powder weight value, the weighing deviation data is calculated and obtained, and when the weighing deviation data exceeds the preset deviation threshold, the powder weighing module is calibrated.

[0581] In this embodiment, when all first measured powder weight values and all second measured powder weight values are measured, all first measured powder weight values and all second measured powder weight values can be calculated to obtain the deviation data.

[0582] The specific calculation method is not limited: it can be but is not limited to obtaining the difference between the one-to-one corresponding first measured powder weight value and the second measured powder weight value, and then summing or averaging all the differences to obtain the weighing deviation data. Or it can be that the average of the sum of all first measured powder weight values and the average of the sum of all second measured powder weight values, the difference between the two averages as the weighing deviation data, etc. Of course, the preset deviation threshold and the weighing deviation data need to be consistent.

[0583] When the weighing deviation data is determined to exceed the preset deviation threshold, the control device 100 can automatically control the powder weight module to directly perform calibration. Alternatively, the control device 100 can prompt the user, and the user can trigger a calibration instruction based on a preset button on the input module to instruct the powder weight module to perform calibration.

[0584] In view of this, in an embodiment, after step P300, the method further comprises:

[0585] Step P400: After completing the calibration operation on the powder weight module, a calibration completion prompt is issued.

[0586] It can be understood that the user is timely prompted by issuing a prompt, so that the user can be timely informed that the calibration operation has been completed, thereby providing the user with the mode required for subsequent operation of the beverage preparation device. The calibration completion prompt can be displayed in, for example, the P5 area in FIG. 13.

[0587] Alternatively, in an embodiment, after step P300, the method further comprises:

[0588] Step P410: After completing the calibration operation on the powder weight module, the powder supply module is controlled to repeatedly discharge in sequence according to the target powder weight values;

[0589] Step P420: When the powder supply module discharges each time, the powder weight module is controlled to receive and weigh the powder to obtain a third weighing powder weight value;

[0590] Step P430: The calibration difference values corresponding one-to-one between the third weighing powder weight values and the first weighing powder weight values are calculated, and when at least one calibration difference value exceeds a preset calibration threshold, the calibration operation on the powder weight module is repeated until all the recalculated calibration difference values do not exceed the calibration threshold, and a calibration completion prompt is issued.

[0591] In the present embodiment, after determining that the calibration operation on the powder weight module is completed, the control device 100 can control the powder supply module to discharge in sequence according to the originally input target powder weight values or according to the newly input target powder weight values. At this time, the number of target powder weight values can remain consistent with before or can be newly input.

[0592] During each discharge of the powder supply module, the above-mentioned weighing operation is repeatedly performed to obtain the third weighing powder weight value of the calibrated powder weight module, and the third weighing powder weight value is compared one-to-one with the previous first weighing powder weight value. If the calibration difference values of both do not exceed the calibration threshold, it is determined that the calibration is effective, and all calibration operations can be completely ended. Conversely, if the calibration difference values of both exceed the calibration threshold, it is determined that the calibration is not in place, and the calibration operation needs to be performed again until all the calibration difference values do not exceed the calibration threshold. The calibration completion prompt can be displayed in, for example, the P5 area in FIG. 13.

[0593] In addition, in an embodiment, after the step of calibrating the powder weight module, the method further comprises:

[0594] Step G500: disabling the input function of the input module before the calibration operation of the powder weight module is completed.

[0595] It can be understood that when the calibration operation of the powder weight module is not completed, by disabling the input function of the input module, the user can be prevented from inputting data that interferes with the current calibration operation based on the input module, resulting in calibration failure.

[0596] After the calibration operation of the powder weight module is completed, the beverage preparation device can execute corresponding modes in response to different instructions.

[0597] Based on any of the above embodiments, it can be understood that the powder weight calibration process can be applied in any suitable scenario, for example, applied in the debugging method of the beverage preparation device described in the first application example. For details, please refer to the first application example section, which will not be described here.

[0598] Seventh application example:

[0599] In the design, the control method of the beverage preparation device is specifically a beverage preparation parameter deployment method, which is applied to a beverage preparation system.

[0600] As shown in FIG. 26, the beverage preparation system includes a central server and a plurality of client devices. The client device includes a second communication connection module, a second information receiving module, and an upgrade module. The second communication connection module is used to establish communication with the central server. The second information receiving module is used to receive the beverage calibration database sent by the central server. The upgrade module is used to update the parameters according to the beverage calibration database.

[0601] Each client device includes a client to be calibrated. The client to be calibrated includes a third communication connection module, a calibration module, and a third information sending module. The third communication connection module is used to establish communication with the central server. The calibration module is used to calibrate the preparation parameters to be calibrated. The third information sending module is used to send the beverage calibration database to the central server.

[0602] Among them, the client device can specifically be the beverage preparation device as described above.

[0603] It can be understood that the client device can generally be provided with multiple, and can be distributed at different spatial areas, for example, when the client device is a coffee machine as described above, it can be a commercial coffee machine applied in each sales store, or it can be a household coffee machine applied in each family. If simply relying on the user to calibrate the preparation parameters of the client device, on the one hand, due to the large number of client devices, the calibration burden is easily increased; on the other hand, due to the unevenness of the user's calibration ability, the calibration effect is easily poor. Overall, it is easy to reduce the user's experience. And the present application sets up a beverage preparation system to create a communication network between the central server and each client device. The central server is generally provided with one, and is located at a relatively fixed position. Based on the communication network, the central server can at least send the calibration data (i.e. the beverage calibration database described below) to each client device, so that the client device automatically completes the calibration with high quality at the same time or almost at the same time. The specific form of the central server is not limited, which can be but is not limited to, for example, a computer, a tablet computer, a mobile phone and the like, or a program software applied in the above-mentioned devices.

[0604] In view of the above, referring to FIG. 9, the beverage preparation parameter deployment method includes:

[0605] Step W100: creating a beverage calibration database and storing the beverage calibration database to the central server;

[0606] In this embodiment, before performing the beverage preparation parameter deployment operation described below, the beverage calibration database is created in advance. It can be understood that the beverage calibration database in this embodiment can generally include at least one type of beverage to be updated and its one-to-one mapping associated preparation parameter to be updated. The type of beverage to be updated is, for example, but not limited to, American coffee, Italian coffee, latte, cappuccino and the like. Since the client device can enable different types and quantities of mechanisms such as bean bin, grinding module, brewing module, milk supply module when preparing different types of beverages, the preparation parameters required by the client device as a whole when preparing different types of beverages, such as the above-mentioned knife disc grinding gap, knife disc starting time, powder weight value, powder thickness, water supply amount, liquid weight, etc. They can be different. By associating the type of beverage with the preparation parameter one by one, when it is determined that the client device can prepare the type of beverage, the complete set of preparation parameters associated with the beverage can be directly updated on the body itself, which has the characteristics of simple operation and excellent effect.

[0607] In actual application, one beverage preparation parameter deployment operation can involve one or several types of beverages, and in order to facilitate distinction, the beverage in the beverage calibration database is named as the beverage to be updated, and the corresponding preparation parameter is named as the preparation data to be updated.

[0608] In particular, the data collected in the beverage tuning database can be empirical data obtained based on empirical knowledge, or theoretical data obtained based on theoretical knowledge, or measured data obtained through a rigorous tuning process in at least one client device.

[0609] When the data collected in the beverage tuning database is measured data, in an embodiment, the step of "creating the beverage tuning database" in step W100 can specifically include:

[0610] Step W110: selecting at least one beverage to be updated, and obtaining the type of the beverage to be updated and the preparation parameter to be tuned;

[0611] Step W120: selecting one of the client devices as a client device to be tuned according to the type of the beverage to be updated and the preparation parameter to be tuned, and establishing communication between the central server and the client device to be tuned;

[0612] Step W130: controlling the client device to be tuned to tune the preparation parameter to be tuned, and obtaining the updated preparation parameter;

[0613] Step W140: establishing a one-to-one mapping relationship between the type of the beverage to be updated and the updated preparation parameter, and forming the beverage tuning database, and sending the beverage tuning database to the central server.

[0614] In this embodiment, at least one beverage to be updated is first selected, and then its type and the associated preparation parameter to be tuned are determined. For example, the type of the beverage to be updated is American coffee, and the associated preparation parameter to be tuned includes at least the burr grinder gap. It should be noted that steps W110 to W140 mainly describe the process of obtaining the updated preparation parameter of one beverage to be updated. When multiple beverages to be updated are involved in the dispensing operation under the same beverage preparation parameter, steps W110 to W140 can be executed repeatedly according to the number of beverages to be updated.

[0615] In step W120, since the types of drinks that can be prepared by the plurality of client devices that establish a communication network with the same central server, the device configurations, etc. are not all consistent among the plurality of client devices, for example, some client devices are fully automatic coffee machines, some client devices are semi-automatic coffee machines, some client devices are a combination of the above-mentioned bean grinder 200 and the brewing machine 300, etc. Therefore, when the type of the drink to be updated and the preparation parameter to be calibrated are determined, a device information suitable for the client device to be calibrated can be selected from the plurality of client devices according to the information. The device information can be, but is not limited to, for example, the above-mentioned mechanism type of the client device, the type of the drink that can be prepared on the client device, the running efficiency of the client device, the running quality of the client device, etc., so as to improve the accuracy of the calibration process and improve the calibration quality as much as possible.

[0616] When the client device to be calibrated is selected, a communication is established with the central server (the specific manner can be referred to step W200 described below). The central server can send the reference parameter related to the calibration process (for example, the preset powder weight, the preset liquid weight and the preset extraction time described below) to the client device to be calibrated. When the reference parameter related to the calibration process does not need to be issued by the central server, but only needs to be manually input by the user based on the input module of the client device to be calibrated, the central server can send an instruction to start the calibration to the client device to be calibrated. When the instruction to start the calibration is received, the client device to be calibrated performs the calibration operation on the preparation parameter of the drink to be updated, and finally obtains the relatively accurate preparation parameter to be updated (the value of a single parameter or the set of values of a plurality of different parameters). The type of the drink to be updated and the preparation parameter to be updated are one-to-one mapping associated.

[0617] Optionally, when there are at least two drinks to be updated, optionally, after each drink to be updated is mapped and associated with the preparation parameter to be updated, it is sent to the central server. After all the drinks to be updated and the preparation parameters to be updated are sent to the central server, they are stored by the central server in a centralized manner, and a drink calibration database is created. Alternatively, after all the drinks to be updated and the preparation parameters to be updated are pre-stored in the client device to be calibrated and form a drink calibration database, the drink calibration database is sent to the central server for storage as a whole.

[0618] The specific scheme for controlling the client device to be calibrated to perform the calibration operation can be referred to the enumeration described below.

[0619] Step W200: Establish a communication between the central server and the client device, and send the drink calibration database to the client device;

[0620] In the embodiment, first, the communication between the central server and the client device needs to be established. There are various solutions, for example, first, the data transmission protocol of the central server and the client device is determined, the communication interface of the central server and the client device is determined, etc.

[0621] Optionally, the identity of the client device can also be identified by the central server. For example, when the central server sends the information of requesting communication to a client device, the client device returns the device information to the central server after receiving the information of requesting communication. The device information can include the type of the organization as described above, and can also include, for example, the product serial number, etc., for the central server to confirm and verify. When the central server confirms and verifies that it is passed, the communication between the two is established, and the data is transmitted.

[0622] Specifically, in an embodiment, the step of "establishing the communication between the central server and the client device" in step W200 can include:

[0623] Step W210: Establish the communication between the central server and all client devices.

[0624] In the embodiment, the communication between the central server and the client device can be established without screening. That is, the central server can directly distribute the beverage adjustment database to all client devices. After receiving the beverage adjustment database, the client device can confirm whether it needs to be adjusted by itself. Or after receiving the beverage adjustment database, the client device can directly trigger the adjustment mode uniformly.

[0625] Or in an embodiment, the step of "establishing the communication between the central server and the client device" in step W200 can include:

[0626] Step W220: Select at least one target client device from each client device, and establish the communication between the central server and the target client device.

[0627] In the embodiment, after the beverage adjustment database is created and stored in the central server, the central server needs to first query and screen all client devices, select the client devices with higher relevance and higher necessity for adjustment according to the beverage adjustment database as target client devices, and establish the communication of the at least one target client device, so as to avoid that the client devices with low relevance or low necessity are forced to establish communication and forced to update parameters.

[0628] Of course, the specific operation of "selecting at least one target client device from each client device" can be:

[0629] Step W221: Obtain the device information of each client device in sequence;

[0630] Step W222: When the device information meets the preset update condition, determining that the client device corresponding to the device information is the target client device.

[0631] In this embodiment, by querying the device information of each client device and performing device information verification, the target client device can be screened out in a shorter time and with higher accuracy. The device information and the preset update condition are correspondingly set, and can be but are not limited to the following:

[0632] In an embodiment, when the beverage calibration database includes at least one type of beverage to be updated as described above, the device information includes the type of beverage that can be prepared, and the preset update condition is met when it is determined that the type of at least one beverage that can be prepared is the same as the type of beverage to be updated. That is, if the type of beverage to be updated in the beverage calibration database is, for example, two types of latte coffee and cappuccino coffee, if a client device can only prepare American coffee and espresso coffee, the client device is not selected as the target client device; if another client device can only prepare latte coffee and American coffee, the client device can be selected as the target client device.

[0633] And / or in an embodiment, the device information includes the type of mechanism, and if the preparation parameter to be updated associated with the beverage to be updated in the beverage calibration database is mainly aimed at the blade parameters of the grinding module, for example, the blade grinding gap, if a client device is only a brewing machine, the client device is not selected as the target client device; if another client device is a fully automatic coffee machine, the client device can be selected as the target client device.

[0634] And / or in an embodiment, the device information includes the running state, and the preset update condition is met when it is determined that the running state is normal. The running state can include but is not limited to the running time, the maintenance state, etc. For example, if the running state of a client device is long-time non-operation, the last maintenance result is unqualified, etc., the client device is not selected as the target client device; if the running state of another client device is appropriate running frequency, the maintenance result is qualified, etc., the client device can be selected as the target client device.

[0635] Of course, it needs to be explained that, for example, the client device is not operated for a long time, the purpose of not updating the client device at present is that the client device may be an alternative client device that is not in use or is basically not in use, or the client device is a device with low use frequency, reducing repeated adjustment of the client device is relatively more conducive to the quality maintenance of the client device. Then, the client device can feed back to the central server, or the central server actively monitors the state of the client device, and when it is determined that the running state of the client device returns to normal, the central server can send the current latest version of the beverage adjustment database to the client device, and confirm that the parameter update of the client device is completed before normal use.

[0636] Step W300: Control the client device to update the parameters according to the beverage adjustment database.

[0637] In this embodiment, when it is determined that the client device that establishes communication with the central server, that is, the target client device receives the beverage adjustment database, the client device can be automatically controlled by the central server to update the parameters according to the beverage adjustment database at the same time or after a certain time based on the central server.

[0638] Or the parameter update prompt can be sent when it is confirmed that the client device receives the beverage adjustment database, prompting the user that there is a new version of the beverage adjustment database, and the user actively confirms whether to update. If the user actively triggers the confirmation update instruction in time, for example, within a set time, the client device is controlled to update the parameters according to the beverage adjustment database based on the central server or based on the target client device itself when the user triggers the confirmation update instruction. Of course, if the user is not timely, for example, still does not actively trigger the confirmation update instruction after exceeding the set time, the central server can directly control the client device to update the parameters according to the beverage adjustment database to ensure the high-quality operation of the target client device.

[0639] In the technical scheme provided in the present application, an information network of a central server and a plurality of client devices is established; when the central server obtains the beverage adjustment database, the central server can establish communication with at least one client device and send the beverage adjustment database to the client device based on the communication, so that the client device updates the parameters according to the beverage adjustment database; especially when the number of client devices that establish communication is large, the one-to-one adjustment of each client device can be simplified, which helps to reduce the overall adjustment workload and improve the overall adjustment efficiency on the one hand, and helps to improve the overall adjustment accuracy on the other hand.

[0640] It can be understood that the central server and the client device capable of achieving the above purposes need to integrate corresponding functional modules.
