[0002] In order to prepare a cup of high-quality beverage, existing beverage preparation equipment generally has a preset powder weight module for weighing the weight of the powder. After the powder weight module weighs the powder to obtain a weight that meets the preset weight, the powder is transferred to the brewing module for brewing and extraction. Therefore, whether the powder weight module measures the weight of the powder accurately affects the quality of the final prepared beverage to a certain extent. During the use of the powder weight module, it is inevitable that measurement deviations will occur. The existing technology cannot simply and efficiently determine whether the powder weight module has measurement deviations, which makes it impossible to calibrate the powder weight module in a timely manner.

[0043] See also Figures 1 to 5 The utility model provides a beverage preparation device. The beverage preparation device includes a body and a control device 100. The present design does not limit the specific type of the beverage preparation device, which can be any device or any product that can extract and brew materials to finally obtain beverages. Specifically, the beverage preparation device can be but is not limited to a coffee machine, a soymilk machine, a food processor, etc. Correspondingly, the materials involved in the utility model can be coffee beans, soybeans and other bean materials. However, for ease of understanding, the beverage preparation device is described as a coffee machine in the following embodiments.

[0044] The machine body at least includes a casing with an inner cavity and a powder supply module arranged in the inner cavity.

[0045] The powder supply module may include a powder storage module, which is used to store and discharge powder. It can be understood that the powder storage module is a structure that directly stores powder. For example, the powder storage module is formed with a powder storage cavity. The powder can be loosely accumulated in the powder storage cavity, or can be stored in the powder storage cavity in the form of capsules, bags, etc. When necessary, the powder storage module directly outputs the powder.

[0046] The powder supply module may include a grinding module, which is used to grind external beans into powder and then discharge it outward. The grinding module may be, but is not limited to, a grinding cylinder and a grinding mechanism. A grinding chamber is formed inside the grinding cylinder; the grinding mechanism, for example, includes two cutter discs that can be relatively movably arranged and a first drive component that drives at least one cutter disc to move. A grinding space is formed between the two cutter discs for performing grinding and crushing operations such as piercing, grinding, and stirring on granular materials such as coffee beans. The grinding gap in the following embodiments refers to the width of the grinding space, that is, the distance between the two cutter discs. Among them, the inlet end of the grinding module is also the inlet end of the grinding cylinder, and coffee beans can be connected to the above-mentioned grinding space; the outlet end of the grinding module is also the outlet end of the grinding cylinder, which can discharge the ground coffee powder outward.

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

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

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

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

[0051] In order to prepare the beverage, the beverage preparation device may further include a brewing module arranged in the housing.

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

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

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

[0055] The water supply component can connect external water to the brewing cylinder to achieve brewing and extraction of the powder cake, and finally obtain beverages such as coffee liquid. When it is necessary to connect water to the brewing cylinder through the water supply component, the water supply component may include a water supply pipeline and a pump body. The required valve body structure (such as a solenoid valve) can be provided at the interface of the water supply pipeline. For example, a pressure sensor for detecting water pressure, a flow sensor for detecting water flow, etc. can be provided at the required pipe section of the water supply pipeline, without limitation.

[0056] When the extraction is completed, the upper piston and / or the lower piston are separated from the brewing cylinder to discharge the extracted coffee powder. The brewing module is connected to the beverage outlet of the whole machine through, for example, a pipeline structure, so that the prepared coffee beverage can be discharged outward.

[0057] In view of the above, the weight of the coffee powder discharged from the outlet of the grinding module is also the powder weight; the weight of the coffee liquid (extracted beverage) discharged from the outlet of the brewing module through the beverage outlet is also the liquid weight. There is no limitation on the measurement method of the powder weight and the liquid weight, which can be obtained by an external, universal weight sensor. Alternatively, it can be obtained by a pre-installed, dedicated weight sensor in the machine body.

[0058] Take the weight sensor as a preset and dedicated example for explanation:

[0059] The machine body may further include a powder weight module.

[0060] In one embodiment, the powder weight module is arranged between the outlet end of the grinding module and the inlet end of the brewing module. The inlet end of the powder weight module can be connected to the outlet end of the grinding module in an on-off manner, and the outlet end of the powder weight module can be connected to the inlet end of the brewing module in an on-off manner. The powder weight module can be fixedly installed in the housing, or it can be detachably installed in the housing. The powder weight module, the grinding module and the brewing module can be relatively fixed or relatively movable. When the powder weight module is moved close to the grinding module manually by the user or automatically driven by a preset power module:

[0061] If the inlet end of the powder weight module is connected to the outlet end of the grinding module, and the outlet end of the powder weight module is closed or disconnected from the inlet end of the brewing module, the powder weight module can receive and accommodate the coffee powder discharged from the outlet end of the grinding module, and perform the weighing function in real time or after the preset grinding time ends. At this time, the powder weight module is in the weighing mode. Of course, the powder weight module can also receive and accommodate the coffee powder discharged from the outlet end of the grinding module, but does not perform the weighing function. At this time, the powder weight module is in the non-weighing pre-receiving mode.

[0062] If the inlet end of the powder weight module is connected to the outlet end of the grinding module, and the outlet end of the powder weight module is connected to the inlet end of the brewing module, the powder weight module is set to a normally open state, so that when the powder is transported from the grinding module to the brewing module, the powder can pass through the powder weight module freely and unimpeded. The powder weight module mainly plays the function of transitioning powder and does not perform the weighing function. At this time, the powder weight module is in a non-weighing transition mode.

[0063] It should be noted that when the powder weight module is applied to the beverage preparation equipment, the powder weight module is placed in the casing as a modular component, and the powder weight module and the casing are quickly disassembled and assembled. An installation area is formed between the grinding module and the brewing module. When the powder weight module is installed in the casing, that is, it is installed in the installation space, and the installation space is filled. However, when the powder weight module is removed from the inside of the casing to the outside, the installation space is vacant: at this time, optionally, in one embodiment, the same detachable connection structure can be correspondingly provided at the powder weight module, the grinding module and the brewing module, and based on the detachable connection structure, the brewing module and the grinding module can be detachably connected to the casing respectively. In particular, when the powder weight module is removed from the outside of the casing to the outside, the position of the original powder weight module in the casing can be supplemented and replaced by moving the brewing module and / or the grinding module to avoid the above-mentioned installation space being vacant, so that the brewing module and the grinding module are as close as possible to avoid the powder material from scattering during the transfer process. Alternatively, in another embodiment, a detachable or integrated but deformable connecting structure may be provided between the grinding module and / or the brewing module. When the powder weight module is installed in the housing, the connecting structure is compressed and deformed to avoid forming the above-mentioned installation space; conversely, when the powder weight module is removed from the housing, the connecting structure is extended and deformed to connect the grinding module and the brewing module to avoid the above-mentioned installation space being vacant. The connecting structure may be a soft rubber channel, etc., and the specific form is not limited.

[0064] In view of the above, the beverage preparation device further includes a control device 100. The control device 100 may be built into the housing or may be external to the housing. The control device 100 may be combined with a preset in-situ sensor to intelligently identify whether the powder reweight module is installed in the housing and whether it is installed in place in the housing, so that whether the powder reweight module is installed or not and whether it is installed in place or not can be flexibly selected, so that the beverage preparation device can be applied to different usage scenarios and realize different usage functions.

[0065] Of course, in one embodiment, the beverage preparation device can manually adjust whether the beverage preparation device is currently in the above-mentioned weighing mode or in the above-mentioned non-weighing mode. Among them, when the powder weight module is in the weighing mode, the powder weight module is generally installed in the casing, and is installed in place in the casing, and the weighing function is enabled. When the powder weight mode is in the non-weighing mode, it can be specifically but not limited to: the powder weight module is not installed in the casing; the powder weight module is installed in the casing but not installed in place; the powder weight module is installed in the casing and installed in place, but the weighing function is not activated, and it may currently be in the above-mentioned non-weighing pre-acceptance mode, or non-weighing transition mode, etc.

[0066] It should be noted that when the powder weight module is in a weighing state, the control device 100 first resets the weighing value of the powder weight module to zero before performing each powder weighing to minimize the impact of powder weight deviation caused by the powder weight module itself.

[0067] Specifically, the powder weight module may include a receiving container 410 and a weighing device 420 connected to each other, wherein 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, wherein the opening and closing member 412 has an open position for conducting the receiving channel, and a closed position for blocking the receiving channel. The container body 411 is roughly cylindrical, and the receiving channel formed therein is elongated and can specifically extend in the up and down directions. At this time, the upper end of the receiving channel constitutes its inlet end, which can be connected to 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 so as to be able to open and cover the outlet end of the receiving channel.

[0068] Of course, corresponding to the brewing module, the machine body may also selectively include a liquid weight module.

[0069] In one embodiment, the housing is generally provided with a beverage outlet at its front panel, and a receiving platform is provided below the beverage outlet. The beverage outlet can be connected to the outlet end of the brewing module. The receiving platform is provided with a water receiving trough for receiving the liquid discharged outward. The receiving platform can also be provided with a grille at the notch of the water receiving trough, and the grille can be used to support at least a container such as a cup, bottle, bowl, can, etc. without hindering the water receiving function of the water receiving trough. The container is used to hold the beverage discharged outward from the beverage outlet.

[0070] The liquid weight module generally includes a tray integrated with a weighing device 420, which can be placed on a receiving platform, and when receiving the coffee liquid discharged from the beverage outlet, the weighing device 420 measures 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.

[0071] In one embodiment, the tray is flippably arranged relative to the front panel, so as to have an activated state when the tray is placed on the receiving table, and an inactivated state when the tray is close to and folded and stored at the front panel. The activated state and the inactivated state can be automatically identified by, for example, the control device 100 and a preset sensor in the beverage preparation device.

[0072] In addition, in one embodiment, the liquid weight module further includes a display component, which is electrically connected to the weighing device 420 to display the measurement results of the weighing device 420. The display component can display any appropriate information according to actual needs, such as directly displaying the actual measurement data of the weighing device 420 in real time, displaying the associated data obtained by converting the actual measurement data, and displaying the status information of the weighing function of the weighing device 420. The display component can be set on the tray, or the display component can be set separately from the tray, such as being placed on the housing.

[0073] Among them, when the liquid weight module itself forms a container for receiving liquid, if the current liquid weight module is in an enabled state, then each time before performing liquid weight measurement, the control device 100 first resets the weighing value of the liquid weight module to zero, so as to minimize the impact of powder weight deviation caused by factors of the liquid weight module itself.

[0074] When the liquid weight module itself is not equipped with a container for holding liquid, but instead holds liquid through an external container, if the current liquid weight module is in an enabled state, each time before performing liquid weight measurement, it first identifies whether there is a container placed on the tray of the liquid weight module. After detecting the weight of the container, the system will reset the weighing value of the liquid weight module to zero.

[0075] It can be understood that the above-mentioned operation of resetting the weighing value of the liquid weight module to zero can be performed before the system runs the beverage preparation mode, for example, before the brewing module starts the extraction operation, and the brewing module is controlled to start the extraction operation only after the weighing value is reset to zero.

[0076] In one embodiment, according to actual needs, the liquid weight module may further include a timer, which may be directly electrically connected to the weighing device 420, or indirectly, for example, by being electrically connected to the control device 100, so as to be associated with the weighing state of the weighing device 420. The timer is configured to have a timing mode and a non-timing mode. When in the timing mode, the timer may record any desired time point and duration during the weighing process of the weighing device 420.

[0077] In particular, after the weighing value of the liquid weight module is reset to zero, the liquid weight module starts timing when it senses the weight of the extracted beverage. Usually, the liquid beverage extracted by the brewing module changes linearly when it falls into the liquid weight module. When the liquid weight module detects that the liquid weight in the container reaches a preset value, the liquid outlet pipeline is instantly cut off at the same time. Alternatively, the brewing module can be controlled to stop extraction (i.e., stop supplying water to the brewing cylinder), or the liquid outlet flow of the extracted beverage can be cut off or the water flow of the extracted beverage can be bypassed and discharged to achieve the purpose of stopping the liquid outlet.

[0078] The powder weight module and / or liquid weight module are used in many beverage preparation equipment. Generally, there are many factors involved in the process of extracting a cup of high-quality coffee with beverage preparation equipment. Among them, the conventional parameters include the ratio between the weight of coffee powder and the weight of the extracted coffee liquid, which usually needs to be controlled within the range of about 1:2 (a certain range of weight deviation is allowed in actual conditions). Of course, the specific powder-liquid weight ratio can be adjusted accordingly according to different coffee bean varieties, the taste of the beverage to be extracted, and various other factors.

[0079] According to different system configuration requirements and in order to realize the functions of various functional modules, the parameter values ​​involved in device detection include but are not limited to the following:

[0080] Table 1 Parameter information of grinding module

[0081] Knife head grinding clearance K The grinding time of the blade start-up is T1 Cutter grinding speed V Parameter Unit mm(mm) S (seconds) r / min (revolutions per minute) Parameter value range 0.01~20mm 0～15 600～2000

[0082] Among them, the parameter value of the blade grinding gap directly determines the particle size of the ground coffee powder, which causes the extraction time to change due to the particle size of the coffee powder when the coffee powder is extracted in the brewing module under the same extraction environment and conditions. In principle, the larger the grinding gap, the larger the particle size of the ground powder, the larger the gap between the particles under the same force in the brewing module, and the faster the water flow during extraction; the opposite is true.

[0083] Specifically in practical applications, preferably, the entire adjustment amount of the cutter disc grinding gap can be divided into multiple gear levels, for example, from -50 to 50, a total of 100 levels, each with a difference value of 0.01mm (the specific number of gear levels can be set by choice, and it is not necessary to set a constant gear), or it can be set to display the actual gap value in real time for adjustment.

[0084] The parameter information of the powder weight module includes: the preset powder weight after grinding by the grinding module can be set, that is, the weight of the powder that can be transferred to the brewing module for extraction. Among them, the parameter range of the preset powder weight setting can vary from 8g to 36g according to the needs of different beverages. After the powder weight module is set in the beverage equipment and the powder weight module is enabled, there is no need to measure the weight of the ground powder by the grinding time of the blade disc. Therefore, after the beverage equipment is set to enable the powder weight module, there is no need to detect and obtain the value of the blade disc grinding time. However, under certain functional requirements, the powder weight module can be enabled and the blade disc grinding time can be detected and obtained at the same time to achieve other additional functions. Please refer to the description of other paragraphs of the utility model specification for further information.

[0085] Table 2 Parameter information table of brewing module

[0086]

[0087] Table 3 Parameter information of liquid weight module

[0088] Parameter information Parameter value range Parameter Unit Preset extraction time T2 15～40 S (seconds) Preset Liquid Weight G2 16～60 g(gram)

[0089] When setting the blade parameters of the grinding module, you first need to adjust the value of the blade grinding gap. The value of the blade grinding gap determines the particle size of the coffee powder after being ground by the grinding module. Too large a particle size will cause the powder cake to be squeezed loosely and the extraction flow rate to be too fast, resulting in insufficient extraction. Too small a particle size will cause the powder cake to be over-squeezed and the extraction water flow to be too slow, resulting in excessive extraction. To obtain a suitable range of particle sizes, you need to adjust the value of the blade grinding gap to a reasonable range. However, with long-term high-speed grinding, the blade will gradually wear, causing the value of the grinding gap between the blades to change. At this time, the beverage preparation equipment needs to have the ability to identify the grinding gap, and be able to adjust the value of the blade grinding gap according to the obtained relevant parameter values ​​to maintain the stable quality of the produced beverages.

[0090] In order to stabilize the quality of coffee extraction and according to the golden cup principle of coffee extraction, to obtain a cup of coffee drink with perfect flavor, there are relevant weight values ​​and proportion requirements for the powder weight of the ground powder and the liquid weight of the extracted coffee liquid. Due to the setting of the powder weight module, the powder weight can be pre-set to allow the beverage preparation equipment to have more precise control over the powder weight during the operation of the equipment. In other implementations, the grinding time of the grinding module at each start and stop is measured to obtain information on the amount / weight of the ground powder.

[0091] Making espresso requires three stages: pre-soaking, flavor extraction, and end-of-extraction. The pre-soaking process is mainly used to remove carbon dioxide and improve extraction efficiency. Before extracting the coffee powder, pre-soaking the extruded powder cake with a certain pressure can effectively improve the flavor of the extracted coffee beverage. The pressure during pre-soaking is defined as the pre-soaking pressure. Before extraction, an appropriate amount of hot water is injected into the coffee powder cake with a certain pressure, so that the powder cake absorbs water in an appropriate amount to release more aroma and flavor. Furthermore, pre-soaking can make the powder cake fully moist, and the water flow during extraction can be better distributed. Of course, the pre-soaking pressure and pre-soaking time can be determined according to a variety of variables such as different coffee bean varieties or powder amounts or powder cake thickness, so the pre-soaking pressure can also be set to 0, that is, pre-soaking is performed using pressure-free water injection, and the pre-soaking time can also be set to 0, that is, the pre-soaking process is not performed.

[0092] Usually, the pre-soaking pressure is set not to be greater than the extraction pressure. The purpose of pre-soaking is to wet the powder cake, and it is not desired that the pre-soaking water flow out of the powder.

[0093] For example, when a powder weight module is pre-set in the beverage preparation device as described above, the powder cake parameter can be expressed by the powder weight obtained by the powder weight module or by the thickness of the powder cake. The powder cake refers to a block structure formed by the powder pressing module (for example, the upper piston and the lower piston are squeezed against each other) in the brewing cylinder after the ground powder is transferred to the brewing cylinder of the brewing module. The thickness of the powder cake can be detected by the movement stroke or distance of the upper piston and / or the lower piston, the sensing of a pre-set position sensor, etc.

[0094] In the beverage preparation device provided by the utility model, after the coffee powder is transferred to the brewing module, the upper piston and the lower piston can be used to extrude the powder with a preset pressure to form a powder cake of a certain thickness, and an extraction process is performed. The extraction process includes a pre-soaking program and an extraction program through a system preset or selectable program setting. An interval can be optionally set between the two time periods of the pre-soaking program and the extraction program to give the pre-soaking program a certain immersion time. Among them, the amount of water used in the pre-soaking program and the extraction program is the total water intake L set in the system. Even if the pre-soaking function is turned off, the total water intake of the extraction is still L. It can be understood that the total water absorption of the coffee powder cake after being extruded and formed will not change much. Regardless of whether it is pre-soaked, when the beverage preparation device needs to obtain a fixed weight of extraction liquid, the required total water intake L is within a fixed value range. Among them, the value of the total water intake L of the extraction process can be accurately measured by a flow meter, a flow valve, a timer, etc. Furthermore, in addition to configuring the pre-soaking program and the extraction program in the extraction process, other programs may be added, which are not limited here, but the total water intake L of the extraction process is a fixed set value.

[0095] In view of the above, the liquid weight module is in an enabled state, and when the liquid weight module measures that there is a container placed on the tray, the liquid weight module first performs an operation of returning the weighing value to zero. In a specific application of the beverage preparation device provided by the present utility model, after a beverage is selected, it can be set that after the liquid weight module measures that the container is in place and returns the weighing value to zero, the grinding module is started to grind the coffee beans; or the grinding module is first started to grind the coffee beans, and then the brewing module is started to perform the brewing procedure after confirming that the liquid weight module measures that the container is in place and returns the weighing value to zero. It can be understood that when the liquid weight module does not detect that there is a container (there is a change in weighing weight) placed on the tray, the grinding module and / or the brewing module will not be started. Of course, the above-mentioned weighing-related programs for the liquid weight module can also be selected to be turned off in the program settings of the beverage preparation device.

[0096] Among them, the total water intake L during the extraction process is to ensure the stability of the liquid output of the beverage after extraction, and can match other parameters to realize the detection and other functions of the beverage preparation equipment. It will be further explained in the implementation mode of the present utility model that until the extraction program is completed, the liquid weight detected by the liquid weight module no longer increases. At this time, the liquid weight module can accurately detect the exact liquid weight of the beverage extracted this time.

[0097] Furthermore, the liquid weight module can be used to measure the total water intake L under a fixed condition. At the moment of stopping the liquid discharge, the liquid weight module confirms the end of liquid discharge and obtains the total water intake L' consumed when the liquid weight is obtained when no continuous increase in liquid weight is detected, so as to perform data conversion and comparison with the preset total water intake L to determine whether the weight of the powder cake meets the requirements. If the actual water intake L' is greater than the preset total water intake L, it will warn that the amount of powder used for extraction is too large. If the actual water intake L' is less than the preset total water intake L, it will warn that the amount of powder used for extraction is too small.

[0098] The parameter values ​​obtained by the above-mentioned grinding module, powder weight module, and liquid weight module are allowed to have a certain deviation range. When the values ​​fall within the deviation range, they are also identified as being in normal working state. The relevant parameter values ​​involved in the utility model are defaulted to include their reasonable deviation range and the reasonable deviation of the system setting. The specific reasonable deviation range is not limited in the utility model, and can be adjusted and set by oneself according to different needs or completed in the beverage preparation equipment. The specific values ​​of the parameter values ​​and their deviation ranges involved in the utility model are schematic values ​​and are not used as a limitation of the values. The adjustment of the schematic values ​​is easy for researchers and developers in this field to think of, and cannot be used as a point to circumvent the present utility model.

[0099] In view of the above, when operating under normal conditions, such as when operating in response to a work instruction, the powder weight module is generally used in conjunction with the powder supply module. For example, the container body 411 in the receiving container 410 receives the powder obtained by grinding the grinding module, and the weighing device 420 weighs the powder to obtain the corresponding powder weight value.

[0100] However, when certain conditions are met, such as when the working time, working frequency, total weighing amount, etc. reach a certain threshold; or when there are changes in the installation environment, built-in mechanical structure, or control program of the powder weighing module, the weighing value of the powder weighing module may need to be calibrated.

[0101] To this end, the beverage preparation device provided by the present invention further includes a weighting part 500. The weighting part 500 is movably arranged relative to the receiving container 410, so as to have a weighing position connected to the receiving container 410, and a separation position disconnected from the receiving container 410. The weighting part 500 is a structure having a fixed weight, such as a metal block such as a weight. For ease of understanding, the fixed weight of the weighting part 500 is uniformly named as a calibration value in the following embodiments, that is, a fixed and known weight value obtained through strict calibration.

[0102] The counterweight part 500 is movable relative to the receiving container 410, so the activity mode of the counterweight part 500 is not limited in this embodiment. The activity mode includes the form of movement, for example, the counterweight part 500 can be switched between the weighing position and the separation position by translation, rotation or other forms of movement. The activity mode also includes the motion trajectory, for example, the counterweight part 500 can be switched between the weighing position and the separation position by moving along a straight line or moving along an arc. The activity mode also includes the driving mode, for example, the counterweight part 500 can be switched between the weighing position and the separation position by manual operation of the user, and can also be driven by a driving mechanism to switch between the weighing position and the separation position. The driving mechanism can be in any suitable form, for example, including a driver such as a motor and a linear cylinder, and can also be composed of transmission components such as a gear set, a gear rack mechanism, a screw nut mechanism, and a rocker mechanism. The driving mechanism can be a separate setting dedicated to driving the counterweight part 500 to move, or it can be a mechanism that is fixed in the beverage preparation equipment.

[0103] It should be noted that the movement mode of the counterweight 500 can be fixed, that is, after assembly, the counterweight 500 is driven by a basically fixed driving mode and along a basically fixed motion trajectory to perform a basically fixed movement. In this case, the counterweight 500 is more suitable for being driven by a driving mechanism.

[0104] Of course, the activity mode of the counterweight 500 can also be arbitrarily variable, that is, after assembly, the counterweight 500 is driven by any variable driving mode and along any variable motion trajectory to perform any variable motion. In this case, the counterweight 500 is more suitable for manual operation by the user.

[0105] In addition, in one embodiment, the beverage preparation device further includes a casing, the powder weight module is accommodated in the casing, and the counterweight part 500 is optionally installed in the casing or outside the casing. The casing can be opened. For example, the casing is provided with an openable cover or door, which can be opened to reveal the inner cavity of the casing, at least the area where the powder weight module and the counterweight part 500 are located is exposed. The driving external force applied by a preset driving mechanism or manually by the user is connected to the counterweight part 500 through the opening of the casing, and then the counterweight part 500 is driven to switch between the weighing position and the separation position.

[0106] Or in one embodiment, the beverage preparation device further includes a housing and a driving mechanism, the counterweight part 500 and the powder weight module are both contained in the housing, and the driving mechanism drives the counterweight part 500 to switch between the weighing position and the separation position. In addition, the powder weight module and the driving mechanism are both electrically connected to the control device 100, so that the start or stop of the driving mechanism, the start, weighing and stop of the powder weight module, etc. are all automatically controlled by the driving device. The driving device can also automatically receive the weighing data of the powder weight module.

[0107] Among them, no matter whether it is installed outside or inside the casing, there is no restriction on the connection method between the counterweight part 500 and the structure to be assembled with it. The structure to be assembled can be defined by any component in the beverage preparation equipment, such as a casing, a grinding module, a brewing module, etc. That is, when in the separated position, the counterweight part 500 is also in a non-working state. Taking the structure to be assembled as a casing as an example, a placement platform can be convexly provided at any outer wall of the casing, and a receiving groove can be concavely provided. Structures such as for placement of the counterweight part 500. Or at least a partial outer wall of the casing and one of the counterweight part 500 are provided with a magnetic attraction structure, and the other is provided with a magnetic matching structure, so that the casing and the counterweight part 500 can be magnetically fixed by the magnetic attraction structure and the magnetic matching structure.

[0108] Specifically, when the work instruction is triggered, the outlet end of the powder supply module is connected to the receiving container 410 to feed powder into the receiving container 410. The counterweight 500 is in a separated position, and the counterweight 500 is set away from the powder flow path between the powder supply module and the receiving container 410. That is, the counterweight 500 will 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.

[0109] When moving to the weighing position, the connection method between the counterweight part 500 and the receiving container 410 in the powder weight module is also not restricted, so that only the counterweight part 500 or the counterweight part 500 receiving container 410 can apply force to the weighing device 420.

[0110] In one embodiment, the receiving container 410 is formed with a receiving cavity; when in the weighing position, the counterweight part 500 is received in the receiving cavity. That is, when the outer diameter of the counterweight part 500 is smaller than the inner diameter of the receiving cavity, the counterweight part 500 can be directly put into the receiving cavity, such as receiving powder, so that the weighing device 420 can weigh the receiving container 410 and the counterweight part 500 as a whole to obtain the weighing value of the counterweight part 500.

[0111] Alternatively, in one embodiment, when in the weighing position, the counterweight 500 is placed on the upper end of the receiving container 410. That is, if the counterweight 500 is closer to the upper end of the receiving container 410 and there is enough space reserved at the upper end of the receiving container 410 for the counterweight 500 to be stably placed, the counterweight 500 can be directly placed on the upper end of the receiving container 410.

[0112] Alternatively, in one embodiment, the receiving container 410 is suspended on one side of the weighing device 420; when in the weighing position, the counterweight 500 is suspended at the lower end of the receiving container 410. That is, if the counterweight 500 is closer to the lower end of the receiving container 410 and there is enough space reserved below the receiving container 410 for the counterweight 500 to be firmly connected, the counterweight 500 can be directly suspended at the lower end of the receiving container 410.

[0113] When in the weighing position, the counterweight 500 and the receiving container 410 may be connected in a contacting manner or in a non-contacting manner, and the connection between the counterweight 500 and the receiving container 410 may be, but is not limited to, magnetic connection, insertion connection, adhesive connection, etc.

[0114] In view of the above, when the measurement instruction is triggered, the weighing part moves to the weighing position, and the weighing device 420 weighs to obtain the weighing value, so that the control device 100 can control the calibration of the powder weight module according to the weighing value and the calibration value of the counterweight part 500.

[0115] In the technical solution provided by the present invention, when the working instruction is triggered, the powder weight module is used normally, the receiving container 410 can receive the powder, and the weighing device 420 weighs the receiving container 410 and the powder received therein as a whole to obtain the weight value of the powder, so as to prepare high-quality beverages; and when the measurement instruction is triggered, the counterweight part 500 moves 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 weighed value of the weight; since the counterweight part 500 has a relatively accurate and knowable weight calibration value, when the deviation between the weighing value and the calibration value does not exceed the deviation threshold, it is basically determined that the current weighing accuracy of the powder weight module is normal and no calibration is required; conversely, when the deviation between the weighing value and the calibration value exceeds the deviation threshold, it is basically determined that the current weighing accuracy of the powder weight module is abnormal and calibration is required. The present application can more intuitively know whether the weighing accuracy of the powder weighing module is abnormal, and can timely calibrate the powder weighing module when an abnormality is found. It has the characteristics of simple structure and efficient operation.

[0116] It can be understood that when the beverage preparation device is equipped with a control device 100 as described above, the control device 100 can receive and analyze the above data, and issue control instructions accordingly. In other embodiments, when the beverage preparation device does not have a dedicated control device 100, an external control device 100 can be selected to implement the above functions.

[0117] 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 obtain the deviation between the calibration value and the weighing value by comparing the two.

[0118] If there is one or more counterweight parts 500, 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, and correspondingly multiple deviations can be obtained. After averaging or screening the deviations, the required deviation can be determined and compared with the preset deviation threshold for analysis.

[0119] If there are several counterweight parts 500 and the calibration values ​​of each counterweight part 500 are different, the counterweight part 500 can also be weighed multiple times. Finally, multiple weighing values ​​corresponding to different calibration values ​​can be obtained, and multiple deviations can be obtained one by one. After averaging or screening the deviations, the required deviation can be determined and compared with the preset deviation threshold for analysis.

[0120] The beverage preparation device also includes an input module. The input module can pre-input parameters as needed, and can also trigger relevant instructions by the user based on a preset trigger module such as a button. Specifically, for example Figure 5As shown, the touch-controlled LCD screen of the beverage preparation device of the present invention can be used as an input module for preset parameters. In addition, the input can also be input from a connected external device, such as a mobile phone, tablet computer, notebook, PDA and other mobile devices to form an input module. In a preferred embodiment, the beverage preparation device is provided with a touch-controlled LCD screen, and the above parameters can be selectively presented on the screen, and the parameter input can be realized by touch.

[0121] When the input module is only used to input parameters or trigger instructions and does not have a display function, the beverage preparation equipment also includes a display module, and the display module is electrically connected to the control device 100. At least the display screen of the display module is exposed outside the casing so that it can be manually operated by the user. Among them, the control button part of the display module constitutes the above-mentioned input module; the display part of the display module can display preset numbers, text, patterns, etc., to assist the user in understanding the status of the current parameter calibration, parameter debugging, normal use and other processes of the beverage preparation equipment. The control interface of the display module will be specifically described below in conjunction with specific drawings. Specifically, in the utility model, the input module and the display module can be simultaneously constituted by a touch-screen LCD screen.

[0122] Specifically, please combine Figure 5 , taking the input module and the display module both represented by a touch LCD display as an example:

[0123] In one embodiment, the input module includes a first triggering unit electrically connected to the control device 100. When triggered, the first triggering unit generates a measurement instruction and sends it to the control device 100. The first triggering unit is, for example, Figure 5 The P1 area in the figure can be expressed in the form of a button. When the first triggering part is triggered by the user, the input module sends a measurement start instruction to the control device 100, and the control device 100 controls, for example, the above-mentioned 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 enable the weighing mode.

[0124] When the first trigger unit triggers the measurement instruction, the counterweight unit 500 repeatedly switches between the weighing position and the separation position for a preset number of times N, so that the weighing device 420 can weigh and obtain N weighing values. That is, if it is necessary to repeatedly measure the same or multiple counterweight units 500, it is necessary to control the driving mechanism with the help of the control device 100, or the user manually operates the counterweight unit 500 to switch between the weighing position and the separation position, and record the weighing values ​​obtained by the measurement.

[0125] Next, in one embodiment, the input module includes an input part electrically connected to the control device 100; when the powder weight module weighs the counterweight part 500, the input part allows the user to input the weighing value and / or calibration value, and sends it to the control device 100. Figure 5 As shown, the input module is preset with a P4 area for the user to manually input the calibration value of the same counterweight part 500 or different counterweight parts 500 at each measurement; and a P5 area for the user to manually input the weighing value obtained at each measurement. Optionally, a P6 area can also be set at the corresponding position of each measurement to display the status of each measurement process, which can be, for example, measurement completed, measuring, not measured; calibration completed, calibrating, or not calibrated, etc., for the user to view intuitively.

[0126] In addition, in one embodiment, the input module includes a second triggering unit electrically connected to the control device 100; when triggered, the second triggering unit generates a calibration instruction and sends it to the control device 100. Figure 5 As shown, the input module is preset 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 triggering form of the calibration instruction. Optionally, when it is determined that the deviation between the weighing value and the calibration value exceeds the deviation threshold, the calibration instruction can be directly triggered automatically by the control device 100.

[0127] Of course, in one embodiment, the input module includes a third trigger unit electrically connected to the control device 100; when triggered, the third trigger unit generates a measurement cancellation instruction and sends it to the control device 100. Figure 5 As shown, the input module is preset with a P2 area for the user to manually trigger the measurement cancellation instruction. When the third trigger part is triggered by the user, the input module sends a measurement cancellation instruction to the control device 100, and the control device 100 controls, for example, the above-mentioned driving mechanism to drive the counterweight part 500 to move 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 material received in the container body 411 is emptied.

[0128] It should be noted that the above structural composition does not constitute a limitation on the specific form of the beverage preparation device. In actual application, the beverage preparation device can be an automated beverage preparation device including the above modules, such as a coffee machine, a soybean milk machine, etc., with grinding function, brewing function and weighing function.

[0129] Take a beverage preparation device including a grinding module and a brewing module as an example: in one application, the grinding module and the brewing module can be assembled in the same housing, that is, integrated into a whole product, such as a fully automatic coffee machine.

[0130] Or in one application, the grinding module and the brewing module can be respectively assembled in two independent and different housings to constitute two independent products. For example, the beverage preparation equipment may include a bean grinder 200 and a brewer 300 (specifically, for example, a semi-automatic coffee machine) that are independently arranged and used in conjunction with each other. Among them, the bean grinder 200 mainly performs the grinding function and the powder weighing function, and the brewer mainly performs the brewing function, the liquid weight weighing function and the extraction time calculation function. At this time, when the above-mentioned powder weight module and liquid weight module are provided, the two can be selectively provided in the bean grinder 200, in the brewer 300, or independently provided compared to the bean grinder and the brewer according to actual needs.

[0131] See also Figure 1 to Figure 2 A preferred embodiment of the present invention is to specifically express the beverage preparation device in the form of a bean grinder 200 and a brewer 300 being separately and independently arranged.

[0132] In this embodiment, the coffee bean grinder 200 and the coffee brewer 300 can be connected to each other by wire or wireless communication. The control device 100 can be selectively arranged in the coffee bean grinder 200, in the coffee brewer 300, or independently arranged compared to the coffee bean grinder and the coffee brewer according to actual needs.

[0133] Furthermore, the beverage preparation device can use a third-party external mobile device. The mobile device can be, but is not limited to, a mobile phone M1, a laptop computer M2, a tablet M3, a PDA, etc. The mobile device can be connected to the control device 100 by wire or wirelessly, which is equivalent to a wired or wireless communication connection with the grinder 200 and the brewer 300.

[0134] The mobile device may constitute the input module in the above or following embodiments. At this time, the values ​​of all preset parameters of the grinder 200 and the brewer 300 are input by the mobile device and transmitted to the control device 100 for storage, call, and execution; or, an input module for inputting preset parameters may be provided in at least one of the grinder 200 and the brewer 300. The input module is different from the above mobile device. Two input modules may be provided, and they are respectively provided in the grinder 200 and the brewer 300, so as to input and manage the parameters of the grinder 200 and the brewer 300 respectively, and the values ​​of all preset parameters of the grinder 200 and the brewer 300 are input by the input module to the control device 100 for storage, call, and execution. Similarly to the above, the input module may be composed of a key module, a touch display module, a plug-in chip module, etc.

[0135] In view of the above, the bean grinder 200 and the brewer 300 can be independently arranged or installed in the same housing. Usually, a powder bowl is arranged between the bean grinder 200 and the brewer 300, and the powder bowl is used to hold the powder obtained by the grinding module and to provide space for brewing and extraction operations (equivalent to the above-mentioned brewing cylinder). The powder bowl can be reciprocated between the bean grinder 200 and the brewer 300, and the driving force during its movement can come from the user's manual control, or from the preset electric control power module. Among them, the powder ground by the bean grinder 200 is weighed by the powder weight component, and then transferred to the powder bowl, and the powder bowl is transferred to the brewer 300 for extraction. However, before the powder bowl receives the powder and transfers it to the brewer 300 for extraction, the powder in the powder bowl needs to be pressed. At this time, the above-mentioned powder pressing module needs to be set. In the embodiment of the utility model, the setting method of the powder pressing module is not limited, and manual pressing can be adopted, or a third-party powder pressing mechanism can be adopted. Preferably, a powder pressing module is provided in the grinder 200 or the brewer 300. After the powder weight component of the grinder 200 transfers the powder to the powder bowl, the powder pressing module is used to press the powder in the powder bowl and then transferred to the brewer 300 for extraction. Alternatively, the powder pressing module can be provided on the brewer 300, and the powder bowl that has received the powder is transferred to the brewer 300, and the powder is pressed first and then the brewing and extraction process is performed. The pressure of the powder pressing module on the powder bowl can be adjusted as a preset parameter.

[0136] Combined with the above description of the bean silo, it can be understood that one or more bean silos can be provided in the grinder 200. When there are several bean silos, each bean silo can store the same or at least partially different coffee beans. Each bean silo can be bound to a variety of different types of beverages, that is, the beverages of the various categories are all made from the beans in one bean silo. In addition, the bean silos can be respectively configured to correspond to the grinding module and / or the brewing module; or at least two bean silos can share one grinding module and / or brewing module.

[0137] Based on any of the above embodiments, one brewing machine 300 can be used with multiple bean grinders 200. Alternatively, one brewing machine 300 can be used with multiple bean bins in one bean grinder 200.

[0138] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
