[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 20, 2023, with application number 202311764980.8 and invention name “A liquid output control method and beverage making equipment”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of automatic control technology, and in particular to a liquid output control method and beverage making equipment. Background Art

[0003] In the tea and coffee beverage industries, to reduce labor costs and improve beverage production efficiency, the use of intelligent liquid dispensing equipment, also known as beverage production equipment, is increasing. These devices can automatically dispense various liquids such as tea, coffee, and sugar according to recipes. Liquid pumps are the primary power mechanism for dispensing liquids in these beverage production devices.

[0004] Typically, a variety of liquid materials need to be added to make a drink, and currently, liquid pumps corresponding to the multiple liquid materials are generally operated simultaneously.

[0005] However, with long-term use, errors will occur in the liquid discharge accuracy of the liquid pump. If multiple liquid pumps work at the same time, the total weight of the drink will not match the expected weight, affecting the user experience. Summary of the Invention

[0020] In a possible implementation, calibrating the liquid pump to be calibrated based on the first weight, the second weight, and a rotation amount of the liquid pump to be calibrated when performing a liquid discharge operation includes:

[0022] Based on the first weight, the second weight, the first number of rotations, and the second number of rotations, the uniform liquid output of the liquid pump to be calibrated is obtained, where the uniform liquid output is the liquid output per unit number of rotations of the liquid pump to be calibrated in a uniform rotation state.

[0023] In one possible implementation, calibrating the liquid pump to be calibrated based on the first weight, the second weight, and a rotation amount of the liquid pump to be calibrated when performing a liquid discharge operation further includes:

[0024] Determining the rotation amount of the liquid pump to be calibrated during the acceleration / deceleration phase according to the acceleration / deceleration phase time of the liquid pump to be calibrated; and

[0026] A beverage making device, comprising:

[0027] An input unit, configured to receive a material formula input by a user, wherein the material formula includes a plurality of target materials required for the current beverage to be prepared and the required weight of each target material;

[0028] Multiple liquid storage tanks, each used to hold different materials;

[0029] a liquid outlet, wherein the plurality of liquid storage tanks are respectively connected to the liquid outlet;

[0030] a plurality of liquid pumps corresponding one to one with the plurality of liquid storage tanks;

[0031] The processor is used to determine the maximum weight target material among the multiple target materials according to the material formula, and the maximum medium weight target material is the target material with the largest required weight; it is also used to control the liquid pumps corresponding to other target materials except the maximum weight target material to perform liquid discharge operations according to the material formula; and after the liquid discharge operations of the other target materials are completed, determine the actual liquid discharge volume of the maximum weight target material according to the current total liquid discharge volume and the total amount of beverages to be produced at present, and control the liquid pump corresponding to the maximum weight target material to perform liquid discharge operations according to the actual liquid discharge volume.

[0032] In a possible implementation, the processor is further configured to, before controlling the liquid pump corresponding to the target material to perform a liquid discharge operation, determine whether the liquid pump corresponding to the target material is a liquid pump to be calibrated;

[0035] The processor controls the liquid pump to be calibrated to perform a first liquid discharge operation to output a first weight of liquid material; controls the liquid pump to be calibrated to perform a second liquid discharge operation to output a second weight of liquid material; and calibrates the liquid pump to be calibrated based on the first weight, the second weight, and the rotation amount of the liquid pump to be calibrated during the liquid discharge operation;

[0036] The sum of the first weight and the second weight is less than the total liquid output of the liquid pump to be calibrated required by the material formula.

[0037] In one possible implementation, when calibrating the liquid pump to be calibrated based on the first weight, the second weight, and the rotation amount of the liquid pump to be calibrated when performing the liquid discharge operation, the processor obtains a first number of rotations and a second number of rotations, the first number of rotations being the rotation amount of the liquid pump to be calibrated when performing the first liquid discharge operation, and the second number of rotations being the rotation amount of the liquid pump to be calibrated when performing the second liquid discharge operation; based on the first weight, the second weight, the first number of rotations, and the second number of rotations, the processor determines the uniform liquid discharge amount of the liquid pump to be calibrated, and the uniform liquid discharge amount is the liquid discharge amount per unit number of rotations of the liquid pump to be calibrated in a uniform rotation state.

Since the maximum weight target material has a relatively small impact on the taste of the beverage and the maximum weight target material is not added preferentially, its actual liquid discharge amount is obtained based on the current total liquid discharge amount and the total liquid discharge amount of the liquid pumps corresponding to the other target materials. Therefore, even if the liquid pump corresponding to the maximum weight target material and / or the liquid pumps corresponding to the other target materials have a problem of inaccurate liquid discharge, the weight of the beverage produced can be guaranteed to be the same as the set weight. Therefore, the control method can suppress the problem of beverage weight deviation even if the liquid pump has a problem of inaccurate liquid discharge, ensure the consistency of beverage weight, and help improve the user experience.

[0044] FIG2 is a flow chart of a liquid output control method provided in this application. DETAILED DESCRIPTION

[0045] The following will be combined with the accompanying drawings to clearly and completely describe the embodiments of this application. Obviously, the described embodiments are only embodiments of one area of ​​this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0046] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0047] As described in the background technology section, when beverage making equipment is used for a long time, its liquid discharge accuracy will deteriorate, resulting in a large deviation in the weight of the beverage, affecting the user experience.

[0048] In addition, if the liquid discharge accuracy of the beverage making equipment deteriorates, the ratio of the various materials in the beverage may not strictly comply with the beverage formula, affecting the taste of the beverage.

[0049] To address these issues, liquid pumps typically require calibration to ensure accurate liquid delivery. Existing calibration methods involve running the pump for a fixed number of revolutions / time, causing liquid to fall into a cup, weighing the volume, and calculating the amount of liquid delivered per unit time / number of revolutions to calibrate the pump. However, the material delivered during this calibration process cannot be accurately mixed with other ingredients to create a finished product recipe, making it unusable for beverage preparation and resulting in material waste.

[0050] Based on the above, the present application provides a liquid output control method, which is applied to a beverage production device. As shown in Figure 1, the beverage production device includes: an input unit 100, multiple liquid storage tanks 200, a liquid outlet 300, multiple liquid pumps 400, and a processor 500. The multiple liquid storage tanks 200 are respectively connected to the liquid outlet 300, and the multiple liquid pumps 400 correspond one-to-one to the multiple liquid storage tanks 200. Each liquid pump 400 is used to output the liquid material in the corresponding liquid storage tank 200 through the liquid outlet 300 in the processor of the processor 500. Based on this, as shown in Figure 2, Figure 2 is a flow chart of a liquid output control method provided by the present application, and the control method includes:

[0051] S1: The input unit 100 receives a material formula input by a user, where the material formula includes a plurality of target materials required for currently making a beverage and a required weight of each target material.

[0052] S2: The processor determines a target material with the largest weight among the multiple target materials according to the material formula, where the target material with the largest weight is the target material with the largest required weight among the multiple target materials.

[0053] S3: After determining the maximum weight target material, the processor 500 controls the liquid pumps corresponding to other target materials except the maximum weight target material to perform liquid discharge operations, that is, controls the liquid pumps corresponding to other target materials except the maximum weight target material to work, and controls the liquid pump corresponding to the maximum weight target material not to work.

[0054] S4: After the liquid pumps corresponding to the other target materials complete the liquid discharge operation, the processor determines the actual liquid discharge volume of the maximum weight target material based on the current total liquid discharge volume and the total amount of the beverage currently to be produced. That is, the actual liquid discharge volume of the maximum weight target material is determined based on the total liquid discharge volume of the liquid pumps corresponding to the other target materials and the total amount of the beverage currently to be produced. After determining the actual liquid discharge volume of the maximum weight target material, the liquid pump corresponding to the maximum weight target material is controlled to perform the liquid discharge operation based on the actual liquid discharge volume.

[0055] Specifically, if the multiple target materials include a first material, a second material, and a third material, and the corresponding required weights are 200g, 100g, and 50g, respectively, and the first material is the target material with the largest weight, then the processor 500 first controls the liquid pumps corresponding to the second and third materials to perform a liquid discharge operation. Then, based on the difference between the total liquid discharge of the liquid pumps corresponding to the second and third materials and the total amount of the beverage to be produced, the actual liquid discharge of the first material is determined. The processor 500 controls the liquid pump corresponding to the first material to output the above-mentioned actual liquid discharge. For example, if the total liquid discharge of the liquid pumps corresponding to the second and third materials is 145g, the actual liquid discharge of the first material is 205g. This allows the first material to be discharged while compensating for the deviation in the liquid discharge of the second and third materials, so that the total amount of the beverage remains unchanged and is the same as the standard weight.

[0056] From the above, it can be seen that this control method can ensure that the weight of the beverage is the same as the standard weight even if the liquid pump has an inaccurate liquid discharge problem, suppress the problem of beverage weight deviation, ensure the consistency of beverage weight, and help improve the user experience.

[0057] Moreover, the target material for liquid output compensation is the material with the largest required weight, which has the least impact on the taste of the beverage. Therefore, this control method can also ensure the consistency of the beverage weight while not affecting the taste of the beverage as much as possible, thereby ensuring the user experience.

[0058] As is known from the foregoing, in order to suppress the problem of inaccurate liquid discharge from the liquid pump, the liquid pump needs to be calibrated. Therefore, in one embodiment of the present application, before the processor controls the liquid pump corresponding to the target material to perform the liquid discharge operation, the control method further includes:

[0059] The processor 500 determines whether the liquid pump 400 corresponding to the target material is a liquid pump to be calibrated;

[0060] If so, the processor 500 calibrates the liquid pump 400 while controlling the liquid pump 400 to discharge liquid according to the material formula. The processor may determine whether the liquid pump 400 is a liquid pump to be calibrated based on the last calibration date of the liquid pump 400.

[0061] Based on the above embodiment, in one embodiment of the present application, during the process in which the processor controls the liquid pump to perform a liquid discharge operation according to the material formula, calibrating the liquid pump includes:

[0062] The processor 500 controls the liquid pump to be calibrated to perform a first liquid discharge operation to output a first weight of material.

[0063] The processor controls the liquid pump to be calibrated to perform a second liquid discharge operation to output a second weight of material.

[0064] The sum of the first weight and the second weight is less than the total liquid output of the liquid pump to be calibrated. The total liquid output of the liquid pump to be calibrated is the required liquid output of the liquid pump to be calibrated, that is, the required weight of the corresponding target material. Therefore, the sum of the first weight and the second weight is less than the required weight of the target material corresponding to the liquid pump to be calibrated.

[0065] If multiple target materials correspond to a liquid pump that is to be calibrated, it means that the liquid pump may have an inaccurate liquid discharge problem. At this time, directly controlling the liquid pump to output the required weight of material at one time is likely to cause the liquid discharge weight to not meet the requirements, affecting the taste of the beverage. For example, if too much liquid is discharged, it is possible that the beverage production cannot continue and the material is wasted. With the control method provided by this patent, if the liquid pump to be calibrated is determined, the liquid pump to be calibrated is controlled to discharge liquid in sections, which helps to more accurately control the liquid discharge volume of the liquid pump to be calibrated, and thus helps to make the liquid discharge volume of the liquid pump to be calibrated closer to the required liquid discharge volume, effectively suppressing the problem of inaccurate liquid discharge due to the liquid pump, and thus helps to ensure the taste of the beverage.

[0066] Moreover, it can be seen from the above that the sum of the liquid output of the liquid pump to be calibrated in sections is less than the required liquid output of the liquid pump to be calibrated. Therefore, the calibration process can be completed during the beverage making process, and no material will be wasted due to calibration.

[0067] Based on the above embodiment, in one embodiment of the present application, calibrating the liquid pump to be calibrated based on the first weight, the second weight, and the rotation amount of the liquid pump to be calibrated when performing the liquid discharge operation includes:

[0068] A first rotation number and a second rotation number are obtained, where the first rotation number is the rotation amount of the liquid pump to be calibrated when performing a first liquid discharge operation, and the second rotation number is the rotation amount of the liquid pump to be calibrated when performing a second liquid discharge operation.

[0069] Based on the first weight, the second weight, the first number of rotations, and the second number of rotations, the uniform liquid output of the liquid pump to be calibrated is obtained. The uniform liquid output is the liquid output per unit number of rotations of the liquid pump to be calibrated when the liquid pump to be calibrated is in a uniform speed state. Specifically, it can be the liquid output per rotation of the liquid pump to be calibrated when the liquid pump to be calibrated is in a uniform speed state. Wherein, the first weight is recorded as W1, the second weight is recorded as W2, the first number of rotations is recorded as C1, the second number of rotations is recorded as C2, and the uniform liquid output of the liquid pump to be calibrated is recorded as Cs, Cs = (W2-W1) / (C2-C1).

[0070] Based on the above embodiment, in one embodiment of the present application, calibrating the liquid pump to be calibrated based on the first weight, the second weight, and the rotation amount of the liquid pump to be calibrated when performing a liquid discharge operation further includes:

[0071] Determining the rotation amount of the liquid pump to be calibrated during the acceleration / deceleration phase according to the acceleration / deceleration phase time of the liquid pump to be calibrated, that is, determining the number of rotations of the liquid pump to be calibrated during the acceleration / deceleration phase; and

[0072] The liquid output of the liquid pump to be calibrated during the acceleration / deceleration phase is determined based on the uniform liquid output of the liquid pump to be calibrated and the rotation amount of the liquid pump to be calibrated during the acceleration / deceleration phase. The liquid output of the liquid pump to be calibrated during the acceleration / deceleration phase is recorded as W3, and the rotation amount of the liquid pump to be calibrated during the acceleration / deceleration phase is recorded as C3. W3 = W1 - (C1 - C3) * Cs.

[0073] It should be noted that after receiving the operation instruction, the liquid pump first accelerates, accelerates to its set speed, and then starts to run at a constant speed, and maintains the constant speed until receiving the stop instruction, and starts to decelerate until it stops rotating. In other words, each working cycle of the liquid pump includes three processes: acceleration stage, constant speed stage and deceleration stage. In addition, for the liquid pump, its speed during constant speed operation is set according to its own performance. Under ideal circumstances, the constant speed liquid output should be constant. However, due to long-term use, the liquid pump's function degrades, and its constant speed liquid output will also undergo degenerative changes. Therefore, it needs to be calibrated at intervals to obtain its current constant speed liquid output. Then, according to the current constant speed liquid output, the operation of the liquid pump is controlled to ensure the liquid output accuracy, thereby suppressing the problem of inaccurate liquid output. In addition, since the liquid pump's uniform liquid output should be constant, and the liquid pump's acceleration phase is from stopping to accelerating to a uniform liquid output, and the deceleration phase is from decelerating to stopping, the number of rotations in the acceleration phase and the number of rotations in the deceleration phase should also be constant. However, due to the functional degradation of the liquid pump, degenerative changes may occur, requiring regular calibration to obtain the current number of rotations in the acceleration and deceleration phases. At the same time, since the number of rotations in the acceleration and deceleration phases is fixed, the corresponding liquid output in the acceleration and deceleration phases should also be fixed. Similarly, degenerative changes may occur as the liquid pump's function degrades.

[0074] Based on the above, in order to ensure the liquid discharge accuracy of the liquid pump and suppress inaccurate liquid discharge, it is necessary to regularly calibrate the uniform liquid discharge volume, the rotation amount in the acceleration / deceleration stage, and the liquid discharge volume in the acceleration / deceleration stage of the liquid pump, and obtain the current uniform liquid discharge volume, the rotation amount in the acceleration / deceleration stage, and the liquid discharge volume in the acceleration / deceleration stage of the liquid pump, that is, obtain the current working parameters of the liquid pump, so as to control the liquid discharge operation of the liquid pump according to the current working parameters of the liquid pump, ensure the liquid discharge accuracy of the liquid pump, and effectively suppress the problem of inaccurate liquid discharge.

[0075] It should be noted that in this embodiment, the rotation amount during the acceleration / deceleration phase includes both the number of acceleration and deceleration cycles, and accordingly, the liquid discharge during the acceleration / deceleration phase includes both the liquid discharge during the acceleration phase and the liquid discharge during the deceleration phase. It should also be noted that even when the liquid pump is operating at a constant speed, its rotational speed is not completely fixed, but rather stabilizes within a certain range. Therefore, the constant liquid discharge is not stable, but rather remains within a stable range. Therefore, this constant liquid discharge must be calculated and cannot be obtained through measurement.

[0076] On the basis of the above embodiment, in one embodiment of the present application, after the liquid pump to be calibrated is calibrated, the control method further includes:

[0077] The processor 500 controls the liquid pump to be calibrated to perform a third liquid discharge operation to output a third weight of material.

[0078] The sum of the first weight, the second weight, and the third weight is equal to the total liquid discharge of the liquid pump to be calibrated. That is, the third liquid discharge operation is a compensation liquid discharge operation, and the third weight is a compensation weight. The purpose is to make the actual liquid discharge of the liquid pump to be calibrated more in line with the required weight of the corresponding target material.

[0079] The processor 402 controls the liquid pump to be calibrated to perform a third liquid discharge operation, and outputting a third weight of material includes:

[0080] A difference is obtained, where the difference is the difference between the third weight and the liquid discharge volume in the acceleration / deceleration stage, so that the third difference is the liquid discharge volume in the uniform speed stage of the third liquid discharge operation.

[0081] The number of uniform-speed revolutions of the liquid pump to be calibrated performing the third liquid discharge operation is obtained based on the ratio of the difference to the uniform-speed liquid discharge amount.

[0082] Based on the number of uniform speed revolutions and the amount of rotation in the acceleration / deceleration stage, the processor controls the liquid pump to be calibrated to perform a third liquid discharge operation to output the third weight of material.

[0083] From the above, it can be seen that after calibrating the liquid pump to be calibrated and obtaining the current working parameters of the liquid pump to be calibrated, the control method obtains the number of uniform speed circles and the number of variable speed circles when performing the third liquid discharge operation based on the current working parameters of the liquid pump to be calibrated, and controls the third liquid discharge operation based on the obtained number of uniform speed circles and the number of variable speed circles when performing the third liquid discharge operation, so that the weight output by the third liquid discharge operation is closer to the third weight, and then the actual liquid discharge volume of the liquid pump to be calibrated is more in line with its required liquid discharge volume, effectively suppressing the problem of inaccurate liquid discharge.

[0084] In one embodiment of the present application, obtaining the number of speed changes of the liquid pump to be calibrated during the first liquid discharge operation includes:

[0085] The acceleration time and deceleration time of the liquid pump to be calibrated during the first liquid discharge operation are obtained.

[0086] The number of acceleration cycles is obtained based on the acceleration time and the acceleration of the liquid pump to be calibrated, and the number of deceleration cycles is obtained based on the deceleration time and the acceleration of the liquid pump to be calibrated. It should be noted that for a liquid pump, its acceleration is related to its own performance and is a default value. Subsequently, the acceleration in the acceleration phase and the deceleration phase is the same and is both based on the default value.

[0087] The sum of the acceleration number and the deceleration number is equal to the speed change number.

[0088] Specifically, the acceleration of the liquid pump to be calibrated is recorded as a, the acceleration time is recorded as T1, and the deceleration time is recorded as T2, then the number of speed change circles C3 = 1 / 2aT1 2 +1 / 2aT2 2 , to obtain the speed change number of the liquid pump to be calibrated, which includes both the acceleration number and the deceleration number.

[0089] Similarly, obtaining the number of speed changes of the liquid pump to be calibrated during the second liquid discharge operation is the same as the above process and will not be repeated here.

[0090] The calibration process of the liquid pump is described in detail below through a specific embodiment.

[0091] For example, if the required liquid output of the liquid pump to be calibrated is 200g, the processor 500 is first used to control the liquid pump to be calibrated to perform a first liquid output operation, with the liquid output being 30%, 200g*0.3=60g. Specifically, the process includes setting the number of rotations for the first liquid output operation, which is slightly greater than the theoretical number of rotations required to output 60g of material, for example, 60g / 5+5=10 rotations, performing real-time weighing via the placement tray 500, and sending a stop command to the liquid pump to be calibrated via the processor 500 when the liquid output is about to reach 60g (for example, when the liquid output reaches 50g). After the liquid pump to be calibrated stops, parameters of the first liquid output operation are obtained and recorded, including the first weight output by the first liquid output operation, the first number of rotations, and the speed change time.

[0092] Then, the processor 500 is used to perform a second liquid discharge operation, with a liquid discharge volume of 70%, 200g*0.7=140g. Specifically, it includes: setting the number of rotations of the second liquid discharge operation, which is slightly larger than the theoretical number of rotations required to output 140g of material, for example, the number of rotations is 140g / 5+5=33 turns, and real-time weighing is performed through the placement plate 500. When the liquid discharge volume is about to reach 140g (for example, when the liquid discharge volume reaches 130g), a stop instruction is sent to the liquid pump to be calibrated through the processor 500. After the calibrated liquid pump stops, the parameters of the second liquid discharge operation are obtained and recorded, including the second weight output by the second liquid discharge operation, the second number of rotations, and the speed change time. It should be noted that the speed change time of the first liquid discharge operation and the second liquid discharge operation are the same, and the preset speeds of the first liquid discharge operation and the second liquid discharge operation are the same.

[0093] The calibration parameters of the liquid pump to be calibrated are obtained by the first weight W1, the first number of rotations C1, the second weight W2, the second number of rotations C2, the acceleration a, the acceleration time T1 and the deceleration time T2: Speed ​​change number C3 = 1 / 2aT1 2 +1 / 2aT2 2; Uniform liquid discharge volume Cs = (W2-W1) / (C2-C1); Variable speed liquid discharge volume W3 = W1-(C1-C3)*Cs.

[0094] It should be noted that the above-mentioned speed-changing liquid output W3 is obtained based on the first weight W1, the first number of rotations C1, the speed-changing number of rotations C3 and the uniform liquid output Cs, but it should be understood that the above-mentioned speed-changing liquid output W3 can also be obtained based on the first weight W2, the first number of rotations C2, the speed-changing number of rotations C3 and the uniform liquid output Cs, in which case the speed-changing liquid output W3 = W2-(C2-C3)*Cs.

[0095] The above embodiment describes the calibration process when the liquid pump to be calibrated is a liquid pump to be calibrated. Similarly, when other liquid pumps are liquid pumps to be calibrated, the calibration process is the same as the calibration process of the liquid pump to be calibrated, and this application will not elaborate on this one by one.

[0096] It should be noted that if there is a liquid pump to be calibrated among the liquid pumps corresponding to multiple target materials, the liquid discharge operation of the liquid pump to be calibrated will be performed first, and calibration will be performed during the liquid discharge operation. After that, the liquid discharge operation of the liquid pumps corresponding to other target materials will be performed. For example, if the required liquid discharge of the liquid pump to be calibrated is 200g, the uniform speed revolution number of the liquid pump to be calibrated is obtained as (200g-W3) / Cs. The variable speed revolution number has been obtained during the calibration process. Based on the uniform speed revolution number and the variable speed revolution number, the liquid discharge operation of the liquid pump to be calibrated can be controlled.

[0097] If there are calibrated liquid pumps corresponding to multiple target materials, the number of uniform speed revolutions and variable speed revolutions for this liquid discharge operation is obtained based on the current operating parameters of the liquid pump recorded after calibration, and the liquid discharge operation of the uncalibrated liquid pump is controlled based on the uniform speed revolutions and variable speed revolutions of this liquid discharge operation. Similarly, if other liquid pumps are calibrated liquid pumps, the number of uniform speed revolutions and variable speed revolutions are also obtained based on the recorded current operating parameters, and the liquid discharge operation of the liquid pump is controlled based on the obtained uniform speed revolutions and variable speed revolutions.

[0098] It should also be noted that the liquid discharge order of the liquid pumps corresponding to target materials other than the target material with the largest weight can be sorted according to the liquid discharge time, for example, in descending order of liquid discharge time. However, this application does not limit this, and the sorting can be based on other conditions, depending on the specific situation.

[0099] Accordingly, the present application also provides a beverage making device, as shown in FIG1 , which includes:

[0100] The input unit 100 is used to receive a material formula input by a user, where the material formula includes a plurality of target materials required for currently making a beverage and a required weight of each target material.

[0101] The plurality of liquid storage tanks 200 are used to store different materials respectively.

[0102] The liquid outlet 300 is connected to the plurality of liquid storage tanks 200 .

[0103] Multiple liquid pumps 400, corresponding one to one with the multiple liquid storage tanks 200

[0104] The processor 500 is used to determine the maximum weight target material among the multiple target materials according to the material formula, and the maximum medium weight target material is the target material with the largest required weight; it is also used to control the liquid pump 400 corresponding to other target materials except the maximum weight target material to perform liquid discharge operation according to the material formula; and after the liquid discharge operation of the other target materials is completed, the actual liquid discharge volume of the maximum weight target material is determined according to the current total liquid discharge volume and the total amount of beverages to be produced at present, and the liquid pump 400 corresponding to the maximum weight target material is controlled to perform liquid discharge operation according to the actual liquid discharge volume.

[0105] As can be seen from the above, the beverage making device first uses a processor to control the liquid pumps corresponding to the target materials other than the target material with the largest weight to discharge liquid. The processor then controls the liquid pump corresponding to the target material with the largest weight to discharge liquid. The liquid discharge volume of the target material with the largest weight is equal to the difference between the total amount of the beverage to be produced and the total liquid discharge volume of the liquid pumps corresponding to the other target materials. Therefore, even if the liquid pump has problems with liquid discharge inaccuracy, the beverage making device can ensure that the weight of the beverage is consistent with the standard weight, thereby suppressing the problem of beverage weight deviation, ensuring consistency of beverage weight, and helping to improve the user experience.

[0106] Moreover, the target material for liquid output compensation is the material with the largest required weight, which has the least impact on the taste of the beverage. Therefore, this control method can also ensure the consistency of the beverage weight while not affecting the taste of the beverage as much as possible, thereby ensuring the user experience.

[0107] Based on the above embodiment, in one embodiment of the present application, the processor 500 is further configured to, before controlling the liquid pump corresponding to the target material to perform a liquid discharge operation, determine whether the liquid pump corresponding to the target material is a liquid pump to be calibrated;

[0108] If so, the processor 500 calibrates the liquid pump 400 during the process of controlling the liquid pump 400 to perform the liquid discharge operation according to the material formula to prevent the problem of inaccurate liquid discharge from the liquid pump.

[0109] Based on the above embodiment, in one embodiment of the present application, the processor 500 is configured to calibrate the liquid pump through the following operations:

[0110] The processor 500 controls the liquid pump to be calibrated to perform a first liquid discharge operation to output a first weight of liquid material; controls the liquid pump to be calibrated to perform a second liquid discharge operation to output a second weight of liquid material; and calibrates the liquid pump to be calibrated based on the first weight, the second weight, and the rotation amount of the liquid pump to be calibrated when performing the liquid discharge operation.

[0111] The sum of the first weight and the second weight is less than the total liquid output of the liquid pump to be calibrated required by the material formula.

[0112] In this embodiment, after determining the liquid pump to be calibrated, the liquid pump to be calibrated is controlled to discharge liquid in sections, and the sum of the discharge volumes is less than the required discharge volume. This helps to more accurately control the discharge volume of the liquid pump to be calibrated, thereby helping to make the discharge volume of the liquid pump to be calibrated closer to the required discharge volume, effectively preventing problems caused by inaccurate liquid pump discharge, and thus helping to ensure the taste of the beverage. At the same time, it prevents the actual discharge volume of the liquid pump to be calibrated from exceeding the required discharge volume. Therefore, even if the material output by the liquid pump to be calibrated is a material that has a significant impact on taste and has high material weight requirements, remedial measures such as more precise discharge operations can be taken in the subsequent process to ensure that the material weight meets the requirements and the taste of the beverage is guaranteed.

[0113] On the basis of the above embodiments, in one embodiment of the present application, when calibrating the liquid pump to be calibrated based on the first weight, the second weight, and the rotation amount of the liquid pump to be calibrated when performing the liquid discharge operation, the processor obtains the first number of rotations and the second number of rotations, the first number of rotations being the rotation amount of the liquid pump to be calibrated when performing the first liquid discharge operation, and the second number of rotations being the rotation amount of the liquid pump to be calibrated when performing the second liquid discharge operation; based on the first weight, the second weight, the first number of rotations, and the second number of rotations, the processor determines the uniform liquid discharge amount of the liquid pump to be calibrated, and the uniform liquid discharge amount is the liquid discharge amount per unit number of rotations of the liquid pump to be calibrated in a uniform rotation state.

[0114] Based on the above embodiments, in one embodiment of the present application, the processor is further used to determine the rotation amount of the liquid pump to be calibrated during the acceleration / deceleration stage based on the acceleration / deceleration stage time of the liquid pump to be calibrated; and to determine the liquid output of the liquid pump to be calibrated during the acceleration / deceleration stage based on the uniform liquid output of the liquid pump to be calibrated and the rotation amount of the liquid pump to be calibrated during the acceleration / deceleration stage.

[0115] It should be noted that the above-mentioned uniform liquid discharge volume, the rotation amount in the acceleration / deceleration stage, and the liquid discharge volume in the acceleration / deceleration stage have been described in detail in the embodiment of the above-mentioned control method and will not be repeated here.

[0116] In summary, the present application provides a liquid output control method and a beverage making device, the control method comprising: an input unit receiving a material formula, the material formula comprising a plurality of target materials required for making a beverage, and the required weight of each target material; a processor determining a maximum weight target material according to the material formula, and controlling the liquid pumps corresponding to the other target materials except the maximum weight target material to perform a liquid discharge operation; then, determining the actual liquid discharge volume of the maximum weight target material according to the current total liquid discharge volume and the current total liquid discharge volume of the beverage to be made, and controlling the liquid pump corresponding to the maximum weight target material to perform a liquid discharge operation according to the actual liquid discharge volume. Since the maximum weight target material has a relatively small effect on the taste of the beverage, and the maximum weight target material is not added preferentially, its actual liquid discharge volume is obtained based on the current total liquid discharge volume and the total liquid discharge volume of the liquid pumps corresponding to the other target materials, so that even if the liquid pump corresponding to the maximum weight target material and / or the liquid pumps corresponding to the other materials have an inaccurate liquid discharge problem, it is possible to ensure that the weight of the beverage produced is the same as the set weight, thereby suppressing the deviation of the beverage weight, ensuring the consistency of the beverage weight, and helping to improve the user experience.
