Technical Field

[0001] This application relates to the field of automatic control technology, and particularly to a liquid output control method and a beverage making device. Background Art

[0002] In industries such as tea beverages and coffee beverages, in order to reduce labor costs and improve the efficiency of beverage production, more and more intelligent liquid output devices, also known as beverage making devices, are adopted, which can automatically output various liquids such as tea soup, coffee, and sugar according to formulas. Among the beverage making devices on the market, liquid pumps are mainly used as the main power mechanism for outputting liquids.

[0003] Generally, making a cup of beverage requires adding multiple liquid materials. Currently, it is generally to make the liquid pumps corresponding to multiple liquid materials work simultaneously.

[0004] However, with long-term use, the liquid output accuracy of the liquid pump will have errors. If multiple liquid pumps work simultaneously, it will cause the total weight of the beverage to not match the expected weight, affecting the user experience. Summary of the Invention

[0005] In view of this, this application provides a beverage making device, and the solution is as follows:

[0006] A liquid output control method is applied to a beverage making device, which includes: an input unit, multiple liquid storage tanks, a liquid outlet, multiple liquid pumps, and a processor.

[0035] Wherein, the sum of the first weight and the second weight is less than the total liquid output required by the material recipe for the liquid pump to be calibrated.

[0036] Optionally, 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 during the liquid discharging operation, the processor obtains a first rotation number of turns and a second rotation number of turns.

[0038] Compared with the prior art, the beneficial effects of the technical solution provided by the present application are as follows:

[0039] The control method provided by the present application includes: an input unit that receives a material formula, and the material formula includes a variety of target materials required for making a beverage and the required weights of each target material. The processor determines the target material with the maximum weight according to the material formula, and controls the liquid pumps corresponding to the other target materials except the target material with the maximum weight to perform liquid discharging operations. Then, according to the current total liquid discharging amount and the total amount of the beverage to be made currently, the actual liquid discharging amount of the target material with the maximum weight is determined, and the liquid pump corresponding to the target material with the maximum weight is controlled to perform a liquid discharging operation according to the actual liquid discharging amount. Since the target material with the maximum weight has a relatively small impact on the taste of the beverage and the target material with the maximum weight is not preferentially added, and its actual liquid discharging amount is obtained according to the total amount of the beverage to be made currently and the total liquid discharging amount of the liquid pumps corresponding to the other target materials, it is ensured that even if there are problems with the liquid discharging accuracy of the liquid pump corresponding to the target material with the maximum weight and / or the liquid pumps corresponding to the other target materials, the weight of the made beverage can be the same as the set weight. Therefore, this control method can suppress the problem of beverage weight deviation and ensure the consistency of the beverage weight even when there are problems with the liquid discharging accuracy of the liquid pump, which helps to improve the user experience. Description of the Drawings

[0040] To more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings described below are only the embodiments of the present application. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on the provided drawings.

[0041] The structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions under which the present application can be implemented. Therefore, they do not have technical essential significance. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present application can produce and the purposes that can be achieved, should still fall within the scope that can be covered by the technical content disclosed in the present application.

[0042] Figure 1 It is a schematic structural diagram of a beverage making device provided by the present application;

[0043] Figure 2 It is a flowchart of a liquid output control method provided by the present application. Detailed implementation manners

[0044] The following will clearly and completely describe the embodiments in the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present application.

[0045] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the drawings and specific implementation manners.

[0046] As described in the background art section, with the long-term use of the beverage making device, its liquid output accuracy will deteriorate, resulting in a large weight deviation of the beverage and affecting the user experience.

[0047] In addition, if the liquid output accuracy of the beverage making device deteriorates, it will also cause the ratio of each material in the beverage not to strictly conform to the beverage formula, affecting the taste of the beverage.

[0048] To solve the above problems, it is usually necessary to calibrate the liquid pump to ensure the liquid output accuracy of the liquid pump. The existing calibration method is to make the liquid fall into the cup by running the liquid pump for a fixed number of revolutions / time, weigh it, and calculate the liquid output per unit time / revolution to calibrate the liquid pump. However, the materials output during the calibration process by the above calibration method cannot be accurately proportioned with other materials into the finished product formula and cannot be used for beverage preparation, resulting in waste of materials.

[0049] Based on the above, the present application provides a liquid output control method, which is applied to a beverage making device, such as Figure 1 shown. The beverage making device includes: an input unit 100, a plurality of liquid storage tanks 200, a liquid outlet 300, a plurality of liquid pumps 400, and a processor 500. The plurality of liquid storage tanks 200 are respectively communicated with the liquid outlet 300. The plurality of liquid pumps 400 correspond to the plurality of liquid storage tanks 200 one by one, and each liquid pump 400 is used to output the liquid material in the corresponding liquid storage tank 200 through the liquid outlet 300 under the control of the processor of the processor 500. Based on this, as Figure 2 shown, Figure 2 is a flowchart of a liquid output control method provided by the present application. The control method includes:

[0050] S1: The input unit 100 receives the material formula input by the user. The material formula includes a variety of target materials required for the currently to-be-made beverage and the required weights of each target material.

[0051] S2: The processor determines the maximum-weight target material among the variety of target materials according to the material formula. The maximum-weight target material is the target material with the largest required weight among the variety of target materials.

[0052] S3: After determining the maximum-weight target material, the processor 500 controls the liquid pumps corresponding to the other target materials except the maximum-weight target material to perform liquid output operations, that is, controls the liquid pumps corresponding to the 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.

[0053] S4: After the liquid output operations of the liquid pumps corresponding to the other target materials are completed, the processor determines the actual liquid output of the maximum-weight target material according to the current total liquid output and the total amount of the currently to-be-made beverage, that is, determines the actual liquid output of the maximum-weight target material according to the total liquid output of the liquid pumps corresponding to the other target materials and the total amount of the currently to-be-made beverage. After determining the actual liquid output of the maximum-weight target material, control the liquid pump corresponding to the maximum-weight target material to perform a liquid output operation according to the actual liquid output.

[0054] Specifically, if 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, then the first material is the target material with the largest weight. First, the processor 500 controls the liquid pumps corresponding to the second material and the third material to perform liquid discharging operations. Then, according to the difference between the total liquid discharge amount of the liquid pumps corresponding to the second material and the third material and the total amount of the beverage to be produced, the actual liquid discharge amount of the first material is determined, and the processor 500 controls the liquid pump corresponding to the first material to output the above actual liquid discharge amount. For example, if the total liquid discharge amount of the liquid pumps corresponding to the second material and the third material is 145g, then the actual liquid discharge amount of the first material is 205g, so that while discharging the first material, the deviation of the liquid discharge amounts of the second material and the third material is compensated, so that the total amount of the beverage remains unchanged and is the same as the standard weight.

[0055] As can be seen from the above, this control method can ensure that the weight of the beverage is the same as the standard weight even when there is a problem with inaccurate liquid discharge of the liquid pump, suppress the problem of beverage weight deviation, ensure the consistency of the beverage weight, and help improve the user experience.

[0056] Moreover, the target material for liquid discharge 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 minimizing the impact on the taste of the beverage and ensuring the user experience.

[0057] As known from the foregoing, in order to suppress the problem of inaccurate liquid discharge of the liquid pump, it is necessary to calibrate the liquid pump. Therefore, in an embodiment of the present application, before the processor controls the liquid pump corresponding to the target material to perform a liquid discharge operation, the control method further includes:

[0058] The processor 500 determines whether the liquid pump 400 corresponding to the target material is a liquid pump to be calibrated;

[0059] If so, during the process of the processor 500 controlling the liquid pump 400 to perform a liquid discharge operation according to the material formula, the liquid pump is calibrated. Among them, the processor can determine whether the liquid pump 400 is a liquid pump to be calibrated according to the last calibration date of the liquid pump 400.

[0060] Based on the above embodiment, in an embodiment of the present application, during the process of the processor controlling the liquid pump to perform a liquid discharge operation according to the material formula, calibrating the liquid pump includes:

[0061] The processor 500 controls the liquid pump to be calibrated to perform a first liquid discharge operation and output a material with a first weight.

[0062] The processor controls the liquid pump to be calibrated to perform a second liquid discharging operation, and outputs materials with a second weight.

[0063] Wherein, the sum of the first weight and the second weight is less than the total liquid discharging amount of the liquid pump to be calibrated. The total liquid discharging amount of the liquid pump to be calibrated is the required liquid discharging amount 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.

[0064] If multiple target materials correspond to a certain liquid pump as the liquid pump to be calibrated, it means that there may be a problem with inaccurate liquid discharging of the liquid pump. At this time, directly controlling the liquid pump to output materials with the required weight at one time is very likely to cause the problem that the liquid discharging weight does not meet the requirements, affecting the taste of the beverage. For example, if the liquid discharging is too much, it may cause the production of this beverage to be unable to continue and the materials to be wasted. By means of the control method provided in this patent, if the liquid pump to be calibrated is determined, the liquid pump to be calibrated is controlled to discharge liquid in segments, which helps to more accurately control the liquid discharging amount of the liquid pump to be calibrated, and further helps to make the liquid discharging amount of the liquid pump to be calibrated closer to the required liquid discharging amount, effectively suppressing the problem of inaccurate liquid discharging of the liquid pump, and further helping to ensure the taste of the beverage.

[0065] Moreover, as can be seen from the above, the sum of the liquid discharging amounts of the liquid pump to be calibrated when discharging liquid in segments is less than the required liquid discharging amount of the liquid pump to be calibrated. Therefore, the calibration process can be completed during the production of the beverage, and the materials will not be wasted due to calibration.

[0066] On the basis of the above embodiments, in an 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 discharging operation includes:

[0067] Obtain a first number of rotation circles and a second number of rotation circles. The first number of rotation circles is the rotation amount when the liquid pump to be calibrated performs the first liquid discharging operation, and the second number of rotation circles is the rotation amount when the liquid pump to be calibrated performs the second liquid discharging operation.

[0068] Based on the first weight, the second weight, the first number of rotation circles, and the second number of rotation circles, obtain the uniform liquid discharging amount of the liquid pump to be calibrated. The uniform liquid discharging amount is the liquid discharging amount per unit rotation circle when the liquid pump to be calibrated is in a uniform state, specifically, it can be the liquid discharging amount per 1 rotation when the liquid pump to be calibrated is in a uniform state. Wherein, the first weight is denoted as W1, the second weight is denoted as W2, the first number of rotation circles is denoted as C1, the second number of rotation circles is denoted as C2, and the uniform liquid discharging amount of the liquid pump to be calibrated is denoted as Cs, and Cs = (W2 - W1) / (C2 - C1).

[0069] Based on the above embodiments, in an 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 during the liquid discharging operation further includes:

[0070] Determine the rotation amount of the liquid pump to be calibrated during the acceleration / deceleration stage according to the acceleration / deceleration stage time of the liquid pump to be calibrated, that is, determine the number of rotation circles of the liquid pump to be calibrated during the acceleration / deceleration stage; and

[0071] Determine the liquid discharge amount of the liquid pump to be calibrated during the acceleration / deceleration stage according to the uniform liquid discharge amount of the liquid pump to be calibrated and the rotation amount of the liquid pump to be calibrated during the acceleration / deceleration stage. Denote the liquid discharge amount of the liquid pump to be calibrated during the acceleration / deceleration stage as W3, and the rotation amount of the liquid pump to be calibrated during the acceleration / deceleration stage as C3, then W3 = W1 - (C1 - C3) * Cs.

[0072] It should be noted that after the liquid pump receives the operation instruction, it first accelerates to run, and after accelerating to its set rotation speed, it starts to run at a uniform speed and maintains the state of uniform running until it receives the stop instruction, and then starts to decelerate until it stops rotating. That is to say, each working cycle of the liquid pump includes three processes: an acceleration stage, a uniform speed stage, and a deceleration stage. And for the liquid pump, its rotation speed during uniform running is set according to its own performance. In an ideal situation, the uniform liquid discharge amount should be constant. However, due to the long-term use of the liquid pump resulting in functional degradation, its uniform liquid discharge amount will also change degeneratively. Therefore, it needs to be calibrated at regular intervals to obtain its current uniform liquid discharge amount, and then control the operation of the liquid pump according to the current uniform liquid discharge amount to ensure the liquid discharge accuracy and thus suppress the problem of inaccurate liquid discharge. In addition, since the uniform liquid discharge amount of the liquid pump should be constant, and the acceleration stage of the liquid pump is from stopping acceleration to the uniform liquid discharge amount, and the deceleration stage is from the uniform liquid discharge amount to decelerating to stop, the number of rotation circles during the acceleration stage and the deceleration stage should also be constant. However, due to the functional degradation of the liquid pump, it will also change degeneratively and needs to be calibrated regularly to obtain the current number of circles during the acceleration / deceleration stage. At the same time, since the number of rotation circles during the acceleration stage and the deceleration stage is fixed, the corresponding liquid discharge amounts during the acceleration stage and the deceleration stage should also be fixed. Similarly, due to the functional degradation of the liquid pump, they will also change degeneratively.

[0073] Based on the above, to ensure the liquid output accuracy of the liquid pump and suppress inaccurate liquid output, it is necessary to regularly calibrate the uniform liquid output volume of the liquid pump, the rotation volume during the acceleration / deceleration stage, and the liquid output volume during the acceleration / deceleration stage, so as to obtain the current uniform liquid output volume of the liquid pump, the rotation volume during the acceleration / deceleration stage, and the liquid output volume during the acceleration / deceleration stage, that is, to obtain the current working parameters of the liquid pump, and to control the liquid output operation of the liquid pump according to the current working parameters of the liquid pump, ensure the liquid output accuracy of the liquid pump, and effectively suppress the problem of inaccurate liquid output.

[0074] It should be noted that in this embodiment, the rotation volume during the above acceleration / deceleration stage includes both the acceleration revolution number and the deceleration revolution number, and correspondingly, the liquid output volume during the above acceleration / deceleration stage includes both the liquid output volume during the acceleration stage and the liquid output volume during the deceleration stage. It should also be noted that even when the liquid pump is in a uniform operation state, its rotation speed is not completely fixed, but is stable within a certain range. Therefore, the uniform liquid output volume is not stable and unchanged either, but is maintained within a stable range. Therefore, it is necessary to calculate the uniform liquid output volume instead of obtaining it through measurement.

[0075] Based on the above embodiment, in an embodiment of the present application, after calibrating the liquid pump to be calibrated, the control method further includes:

[0076] The processor 500 controls the liquid pump to be calibrated to perform a third liquid output operation and output a material with a third weight.

[0077] The sum of the first weight, the second weight, and the third weight is equal to the total liquid output volume of the liquid pump to be calibrated. That is to say, the third liquid output operation is a compensation liquid output operation, and the third weight is a compensation weight, aiming to make the actual liquid output volume of the liquid pump to be calibrated more in line with the required weight of the corresponding target material.

[0078] Wherein, the processor 402 controls the liquid pump to be calibrated to perform a third liquid output operation and output a material with a third weight, including:

[0079] Obtain a difference, where the difference is the difference between the third weight and the liquid output volume during the acceleration / deceleration stage, so that the third difference is the liquid output volume during the uniform stage of the third liquid output operation.

[0080] Based on the ratio of the difference to the uniform liquid output volume, obtain the uniform revolution number of the liquid pump to be calibrated for the third liquid output operation.

[0081] Based on the uniform revolution number and the rotation volume during the acceleration / deceleration stage, the processor controls the liquid pump to be calibrated to perform a third liquid output operation and output the material with the third weight.

[0082] As can be seen from the above, 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 constant-speed revolution number and variable-speed revolution number during the third liquid discharging operation based on the current working parameters of the liquid pump to be calibrated, and controls the third liquid discharging operation based on the obtained constant-speed revolution number and variable-speed revolution number during the third liquid discharging operation, so that the weight output by the third liquid discharging operation is closer to the third weight, and further makes the actual liquid discharge volume of the liquid pump to be calibrated more in line with its required liquid discharge volume, effectively suppressing the problem of inaccurate liquid discharge.

[0083] In an embodiment of the present application, obtaining the variable-speed revolution number of the liquid pump to be calibrated during the first liquid discharging operation includes:

[0084] Obtaining the acceleration time and deceleration time of the liquid pump to be calibrated during the first liquid discharging operation.

[0085] Based on the acceleration time and the acceleration of the liquid pump to be calibrated, the acceleration revolution number is obtained, and based on the deceleration time and the acceleration of the liquid pump to be calibrated, the deceleration revolution number is obtained. It should be noted that for a liquid pump, its acceleration is related to its own performance and is a default value. Subsequently, the accelerations in the acceleration stage and the deceleration stage are the same, both being this default value.

[0086] The sum of the acceleration revolution number and the deceleration revolution number is equal to the variable-speed revolution number.

[0087] Specifically, denoting the acceleration of the liquid pump to be calibrated as a, the acceleration time as T1, and the deceleration time as T2, then the variable-speed revolution number C3 = 1 / 2aT1 2 + 1 / 2aT2 2 , to obtain the variable-speed revolution number of the liquid pump to be calibrated, which includes both the acceleration revolution number and the deceleration revolution number.

[0088] Similarly, the process of obtaining the variable-speed revolution number of the liquid pump to be calibrated during the second liquid discharging operation is the same as the above process and will not be elaborated here.

[0089] The calibration process of the liquid pump will be described in detail below through a specific embodiment.

[0090] For example, if the required liquid output of the liquid pump to be calibrated is 200 g, first, the processor 500 is used to control the liquid pump to be calibrated to perform the first liquid output operation, and the liquid output is 30%, 200 g * 0.3 = 60 g. Specifically, it includes: setting the number of rotation cycles of the first liquid output operation, which is slightly greater than the theoretical number of cycles required to output 60 g of material. For example, the number of rotation cycles is 60 g / 5 + 5 = 10 cycles. Through the placement tray 500, real-time weighing is carried out. When the liquid output is about to reach 60 g (for example, when the liquid output reaches 50 g), a stop instruction is sent to the liquid pump to be calibrated through the processor 500. After the liquid pump to be calibrated stops, the 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 rotation cycles, and the variable speed time.

[0091] Then, the processor 500 is used to perform the second liquid output operation, and the liquid output is 70%, 200 g * 0.7 = 140 g. Specifically, it includes: setting the number of rotation cycles of the second liquid output operation, which is slightly greater than the theoretical number of cycles required to output 140 g of material. For example, the number of rotation cycles is 140 g / 5 + 5 = 33 cycles. Through the placement tray 500, real-time weighing is carried out. When the liquid output is about to reach 140 g (for example, when the liquid output reaches 130 g), a stop instruction is sent to the liquid pump to be calibrated through the processor 500. After the liquid pump to be calibrated stops, the parameters of the second liquid output operation are obtained and recorded, including the second weight output by the second liquid output operation, the second number of rotation cycles, and the variable speed time. It should be noted that the variable speed times of the first liquid output operation and the second liquid output operation are the same, and the preset rotation speeds of the first liquid output operation and the second liquid output operation are the same.

[0092] The calibration parameters of the liquid pump to be calibrated are obtained through the first weight W1, the first number of rotation cycles C1, the second weight W2, the second number of rotation cycles C2, the acceleration a, and the acceleration time T1 and deceleration time T2:

[0093] Variable speed number of cycles C3 = i / 2aT1 2 + 1 / 2aT2 2 ;

[0094] Constant speed liquid output Cs = (W2 - W1) / (C2 - C1);

[0095] Variable speed liquid output W3 = W1 - (C1 - C3) * Cs.

[0096] It should be noted that the above variable speed liquid output W3 is obtained based on the first weight W1, the first number of rotation cycles C1, the variable speed number of cycles C3, and the constant speed liquid output Cs. However, it should be understood that the above variable speed liquid output W3 can also be obtained based on the first weight W2, the first number of rotation cycles C2, the variable speed number of cycles C3, and the constant speed liquid output Cs. In this case, the variable speed liquid output W3 = W2 - (C2 - C3) * Cs.

[0097] The above embodiments describe the calibration process when the liquid pump to be calibrated is the liquid pump to be calibrated. Similarly, when other liquid pumps are the liquid pumps to be calibrated, the calibration process is the same as that of the liquid pump to be calibrated, and the present application will not elaborate on this one by one.

[0098] It should be noted that if there is a liquid pump to be calibrated among the liquid pumps corresponding to multiple target materials, then the liquid discharge operation of the liquid pump to be calibrated is preferentially performed, and calibration is carried out during the liquid discharge operation. After that, the liquid discharge operation of the liquid pumps corresponding to other target materials is carried out. For example, if the required liquid discharge volume of the liquid pump to be calibrated is 200 g, the uniform rotation speed number of turns of the liquid pump to be calibrated = (200 g - W3) / Cs, and the variable speed number of turns has been obtained during the calibration process. Based on the uniform rotation speed number of turns and the variable speed number of turns, controlling the liquid pump to be calibrated to perform the liquid discharge operation is sufficient.

[0099] And if there is a calibrated liquid pump among the liquid pumps corresponding to multiple target materials, then according to the current working parameters of the liquid pump recorded after calibration, the uniform rotation speed number of turns and the variable speed number of turns of this liquid discharge operation are obtained, and then the liquid pump to be calibrated is controlled to perform the liquid discharge operation according to the uniform rotation speed number of turns and the variable speed number of turns of this liquid discharge operation. Similarly, when other liquid pumps are calibrated liquid pumps, the uniform rotation speed number of turns and the variable speed number of turns are also obtained based on the recorded current working parameters, and then the liquid discharge operation of the liquid pump is controlled according to the obtained uniform rotation speed number of turns and variable speed number of turns.

[0100] It should also be noted that the liquid discharge order of the liquid pumps corresponding to other target materials except the target material with the maximum weight can be sorted according to the liquid discharge duration. For example, the liquid discharge is carried out in the order from the longest to the shortest liquid discharge duration. However, the present application does not make any limitations on this, and it can be sorted according to other conditions, depending on the specific situation.

[0101] Correspondingly, the present application also provides a beverage making device, as Figure 1 shown, the beverage making device includes:

[0102] An input unit 100, configured to receive a material recipe input by a user, where the material recipe includes a variety of target materials required for the currently to-be-made beverage, and the required weights of each target material.

[0103] A plurality of liquid storage tanks 200, respectively used for storing different materials.

[0104] A liquid discharge port 300, and the plurality of liquid storage tanks 200 are respectively communicated with the liquid discharge port 300.

[0105] A plurality of liquid pumps 400, in one-to-one correspondence with the plurality of liquid storage tanks 200

[0106] A processor 500 is configured to determine the target material with the maximum weight among the multiple target materials according to the material formula, where the target material with the maximum weight is the target material with the largest required weight; it is also configured to control the liquid pumps 400 corresponding to the other target materials except the target material with the maximum weight to perform liquid discharging operations according to the material formula; and after the liquid discharging operations of the other target materials are completed, determine the actual liquid discharging amount of the target material with the maximum weight according to the current total liquid discharging amount and the total amount of the beverage to be produced, and control the liquid pump 400 corresponding to the target material with the maximum weight to perform a liquid discharging operation according to the actual liquid discharging amount.

[0107] As can be seen from the above, the beverage production device first controls the liquid pumps corresponding to the other target materials except the target material with the maximum weight among the multiple target materials to perform liquid discharging operations through the processor, and then controls the liquid pump corresponding to the target material with the maximum weight to perform a liquid discharging operation through the processor. And the liquid discharging amount of the target material with the maximum weight is equal to the difference between the total amount of the beverage to be produced and the total liquid discharging amount of the liquid pumps corresponding to the other target materials. Therefore, even if there is a problem with inaccurate liquid discharging of the liquid pump, the beverage production device can ensure that the weight of the beverage is the same as the standard weight, suppress the problem of beverage weight deviation, ensure the consistency of the beverage weight, and help improve the user experience.

[0108] Moreover, the target material for which liquid discharging amount compensation is performed is the material with the largest required weight, which has the least impact on the taste of the beverage. Thus, this control method can also ensure the consistency of the beverage weight while minimizing the impact on the taste of the beverage as much as possible, guaranteeing the user experience.

[0109] Based on the above embodiments, in an 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 discharging operation, determine whether the liquid pump corresponding to the target material is a liquid pump to be calibrated;

[0110] If so, the processor 500 calibrates the liquid pump 400 during the process of controlling the liquid pump 400 to perform a liquid discharging operation according to the material formula to suppress the problem of inaccurate liquid discharging of the liquid pump.

[0111] Based on the above embodiments, in an embodiment of the present application, the processor 500 is configured to calibrate the liquid pump through the following operations:

[0112] The processor 500 controls the liquid pump to be calibrated to perform a first liquid discharging operation to output a liquid material with a first weight; controls the liquid pump to be calibrated to perform a second liquid discharging operation to output a liquid material with a second weight; 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 discharging operation.

[0113] Wherein, the sum of the first weight and the second weight is less than the total liquid output required by the material formula for the liquid pump to be calibrated.

[0114] In this embodiment, after determining the liquid pump to be calibrated, the liquid pump to be calibrated is controlled to discharge liquid in segments, and the sum of the liquid discharge amounts is less than the required liquid discharge amount, which helps to more accurately control the liquid discharge amount of the liquid pump to be calibrated, and further helps to make the liquid discharge amount of the liquid pump to be calibrated closer to the required liquid discharge amount, effectively suppressing the problem of inaccurate liquid discharge of the liquid pump, and further helping to ensure the taste of the beverage. At the same time, it is avoided that the actual liquid discharge amount of the liquid pump to be calibrated is greater than its required liquid discharge amount. Thus, even if the material output by the liquid pump to be calibrated is a material that has a greater impact on the taste and has higher requirements for the material weight, in the subsequent process, through some remedial measures, such as more accurate liquid discharge operations, etc., the weight of the material can meet the requirements and the taste of the beverage can be ensured.

[0115] Based on the above embodiments, in an 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 during the liquid discharge operation, the processor obtains a first rotation number of turns and a second rotation number of turns. The first rotation number of turns is the rotation amount when the liquid pump to be calibrated performs the first liquid discharge operation, and the second rotation number of turns is the rotation amount when the liquid pump to be calibrated performs the second liquid discharge operation; based on the first weight, the second weight, the first rotation number of turns, and the second rotation number of turns, 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 turn of the liquid pump to be calibrated in a uniformly rotating state.

[0116] Based on the above embodiments, in an embodiment of the present application, the processor is further configured to determine the rotation amount of the liquid pump to be calibrated during the acceleration / deceleration stage according to the acceleration / deceleration stage time of the liquid pump to be calibrated; and determine the liquid discharge amount of the liquid pump to be calibrated during the acceleration / deceleration stage according to the uniform liquid discharge amount of the liquid pump to be calibrated and the rotation amount of the liquid pump to be calibrated during the acceleration / deceleration stage.

[0117] It should be noted that the above uniform liquid discharge amount, the rotation amount during the acceleration / deceleration stage, and the liquid discharge amount during the acceleration / deceleration stage have been described in detail in the embodiments of the above control method, and will not be elaborated here.

[0118] In summary, the present application provides a liquid output control method and a beverage making device. The control method includes: an input unit receives a material recipe, which includes a variety of target materials required for the beverage to be made and the required weights of each target material; a processor determines the target material with the maximum weight according to the material recipe, and controls the liquid pumps corresponding to the other target materials except the target material with the maximum weight to perform a liquid output operation. Then, according to the current total liquid output and the total amount of the beverage to be made currently, the actual liquid output of the target material with the maximum weight is determined, and the liquid pump corresponding to the target material with the maximum weight is controlled to perform a liquid output operation according to the actual liquid output. Since the target material with the maximum weight has a relatively small impact on the taste of the beverage and is not preferentially added, its actual liquid output is obtained according to the total amount of the beverage to be made currently and the total liquid output of the liquid pumps corresponding to the other target materials, so that even if there are problems with inaccurate liquid output of the liquid pump corresponding to the target material with the maximum weight and / or the liquid pumps corresponding to other materials, it can ensure that the weight of the made beverage is the same as the set weight, suppress the weight deviation of the beverage, ensure the consistency of the beverage weight, and help improve the user experience.
