Description

Technical Field

[0001] The present invention relates to the field of self-service coffee brewing, and in particular to a machine for automatically brewing beverages. Background Art

[0002] With the development of science and technology, many commodities have been sold by themselves. Since it is self-service, sales staff is no longer needed, which significantly reduces labor costs for merchants. For pre-packaged products, self-service sales are relatively simple, as long as the goods are shipped. However, for hot and cold drinks such as coffee and tea that are not suitable for pre-packaging and need to be brewed on site, self-service sales technology has not been particularly successful. The main reason is how to ensure the freshness of raw materials, reduce material loss, determine the state of ingredients, accurately put in the set amount, and avoid the waste of raw materials as much as possible. It is difficult to achieve a satisfactory level. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a machine for automatically brewing beverages.

[0004] The specific technical solution of the present invention to solve the above technical problems is:

[0005] A machine for automatically brewing beverages, comprising a main control system, a steam water heater, an ice maker, an ice storage bin, a refrigerator, a liquid auxiliary material bin, and a cup bin, wherein the main control system pre-stores brewing programs for several types of beverages, wherein the brewing programs include the names and quantities of the required materials, the order of adding each material, and the required pre-operations, wherein the pre-operations include frothing processing; the steam water heater is used to provide hot water and steam at a temperature not lower than 95° C. at any time; the ice bin is used to store granular ice cubes; the ice maker is used to make granular ice cubes; the refrigerator is used to store several liquid auxiliary materials; the cup bin is used to store hand-brewed cup materials; according to external selection instructions, the preset beverage brewing program in the main control system is called to brew the corresponding beverage; a connecting pipe is provided between the hot water outlet and the steam outlet of the steam water heater, and a solenoid valve is provided on the connecting pipe, and the main control system controls the steam to heat the outlet water as needed, and the hot water outlet is made of a poor thermal conductor to ensure that the outlet water temperature is not lower than 95° C.

[0006] Preferably, the ice maker also has the function of dispensing ice water.

[0007] Preferably, an ice quantity detector, an ice outlet bin door and an ice discharging weighing scale are provided inside the ice maker, and the opening degree of the ice outlet bin door is adjustable; when the ice quantity detector detects that the ice quantity in the ice bin is insufficient, the main control system controls that the single-system cannot dispense cold drinks; at the initial stage of ice discharging, the ice outlet bin door is fully opened, and the ice maker starts to discharge ice. When the ice discharging weighing scale detects that the discharged ice quantity reaches the first threshold value of the required ice quantity, the main control system controls the ice outlet bin door to be adjusted to the second opening degree, and only one ice granule is allowed to pass through the second opening degree each time; when the ice discharging weighing scale detects that the discharged ice quantity reaches the required ice quantity, the main control system controls the ice outlet bin door to close, and the ice discharging ends.

[0008] Thus, the ice discharging quantity is accurately controlled, and the error can be controlled within the weight range of one ice granule.

[0009] Preferably, a sleeve is further provided on the outer periphery of the discharging pipe of the liquid auxiliary material. An auxiliary material electric control valve is provided on the part of the discharging pipe located inside the refrigerating box. A cleaning water pipe is communicated between the auxiliary material electric control valve and the discharging port, and a cleaning water valve is provided on the cleaning water pipe; after each cup is brewed, the main control system controls the auxiliary material electric control valve to close and the cleaning water valve to open, and the pipeline after the auxiliary material electric control valve of the discharging pipe is cleaned to prevent the auxiliary materials not stored in the refrigerated environment in this section of the pipeline from deteriorating and affecting the product quality.

[0010] Preferably, a plurality of liquid auxiliary material bins are provided inside the refrigerating box. Each liquid auxiliary material bin is used for placing different categories of liquid auxiliary materials. A large barrel of auxiliary material or a small barrel of auxiliary material is placed in each liquid auxiliary material bin. Different auxiliary materials can be placed in each bin, or the same auxiliary materials can be placed in several bins. The main control system regularly counts the usage amount of each liquid auxiliary material within a certain period, and continuously iteratively updates the demand prediction model of a certain liquid auxiliary material for the next day to prompt the staff to prepare the corresponding amount of liquid auxiliary materials.

[0011] By continuously iteratively updating the prediction model, the consumables required for the next day can be accurately predicted, and waste can be avoided.

[0012] Preferably, the main control system also uses holidays and the next day's weather forecast as parameters of the prediction model, that is, a set of prediction parameters for weekdays and another set of prediction parameters for non-working days;

[0013] If the predicted maximum temperature exceeds 40°C, the predicted demand for the auxiliary materials for cold drinks is multiplied by a coefficient a on the daily predicted value, where the coefficient a = 6;

[0014] If the predicted maximum temperature is between 30°C and 39°C, the coefficient a satisfies: 1.0 < a ≤ 6.0, and for each 1°C increase, the coefficient a increases by 0.5;

[0015] If the predicted temperature is 30°C or below, the coefficient a = 1.

[0016] Further factors considered in the prediction are added to improve the prediction accuracy.

[0017] Preferably, if it is detected that an opened liquid auxiliary material has been exhausted, the predicted demand for the liquid auxiliary material for the day is updated based on the predicted demand for the liquid auxiliary material for the day and the ratio of the amount already consumed on the day, and the ratio of the business hours already opened on the day to the total business hours, and the estimated consumption and the estimated remaining amount by closing time when a new liquid auxiliary material is opened are further calculated. If the expected profit brought by the estimated consumption is greater than the purchase value of the estimated remaining amount, the corresponding product is displayed as available for ordering, otherwise the system displays "Sold out".

[0018] Therefore, when the store is close to closing, it is not appropriate to open new materials to avoid waste caused by excessive remaining consumables opened that day.

[0019] Preferably, the cup bin contains multiple cup tubes for placing different hand-brewed cup products. Each cup tube is provided with a cup quantity counter and a cup drop controller. The main control system controls the corresponding cup drop controller to release the hand-brewed cup material according to the user's selection. The cup quantity warning value can be set. When the cup quantity counter detects that the hand-brewed cup is lower than the warning value, the staff is prompted to replenish it in time. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0025] A machine for automatically brewing beverages, including a main control system, a steam water heater 1, an ice storage bin, an ice maker 2, a refrigerator 3, a liquid auxiliary material bin, and a cup bin. The main control system is preset with brewing programs for several types of beverages, and the brewing program includes the name and quantity of the required materials, the order of adding each material, and the required pre-operation, and the pre-operation includes frothing. The steam water heater 1 is used to provide hot water and steam at a temperature not lower than 95°C at any time. The ice storage bin is used to store ice cubes. The ice maker 2 is used to make ice cubes. The refrigerator 3 is provided with a liquid auxiliary material bin for storing different liquid auxiliary materials that need to be refrigerated. The cup bin is used to store several hand-brewed cup materials. According to the external selection instruction, the preset beverage brewing program in the main control system is called to brew the corresponding beverage.

[0026] In this embodiment, specifically, the ice maker 2 also has the function of dispensing ice water.

[0027] The ice maker 2 is provided with an ice quantity detector, an ice discharging bin door and an ice discharging metering scale, and the opening degree of the ice discharging bin door is adjustable; when the ice quantity detector detects that the amount of ice in the ice bin is insufficient, the main control system controls the ordering process so that cold drinks cannot be ordered; at the initial stage of ice discharging, the ice discharging bin door is fully opened, and the ice maker 2 starts to discharge ice. When the ice discharging metering scale detects that the amount of ice discharging reaches 80% of the required amount of ice, the main control system controls the ice discharging bin door to be adjusted to a second opening degree, and the second opening degree only allows one ice particle to pass through at a time; when the ice discharging metering scale detects that the amount of ice discharging reaches the required amount of ice, the main control system controls the ice discharging bin door to be closed, and ice discharging ends.

[0028] In the present embodiment, specifically, the discharge pipe of the liquid auxiliary material bin is located in the cold storage box 3 and an auxiliary material electric-controlled valve is provided near the outlet end, a cleaning water pipe is connected between the auxiliary material electric-controlled valve and the discharge port, and a cleaning water valve is provided on the cleaning water pipe; after each cup of brewing, the main control system controls the auxiliary material electric-controlled valve to close and the cleaning water valve to open, and clean the pipeline after the auxiliary material electric-controlled valve of the discharge pipe, so as to avoid the auxiliary materials remaining in the auxiliary material pipelines outside the cold storage box 3 from deteriorating because they are not in a refrigerated environment, thereby ensuring the quality of each cup of product.

[0029] In this embodiment, specifically, the refrigerator 3 is provided with several liquid auxiliary material bins, which can be used to store different types of liquid auxiliary materials. Each bin can store a large barrel of auxiliary materials or a small barrel of auxiliary materials. Different auxiliary materials can be placed in each bin, or the same auxiliary materials can be placed in several bins. The main control system regularly counts the amount of each liquid auxiliary material used in a certain period of time, and continuously iterates and updates the demand prediction model for a certain liquid auxiliary material the next day, so as to prompt the staff to prepare the corresponding amount of liquid auxiliary materials.

[0030] In this embodiment, specifically, holidays and the weather forecast for the next day are also used as parameters of the prediction model, that is, working days are one set of prediction parameters, and non-working days are another set of prediction parameters;

[0031] If the predicted temperature exceeds 40°C, the demand for the auxiliary materials required for cold drinks is multiplied by the coefficient a on the daily predicted value, where the coefficient a = 6;

[0032] If the predicted temperature is between 30°C and 39°C, the coefficient a satisfies: 1.0 < a ≤ 6.0. For every 1°C increase, the coefficient a increases by 0.5. That is, when the predicted maximum temperature is 30°C, a = 1.5; when it is 31°C, a = 2.0, and so on;

[0033] If the predicted temperature is 29°C or below, the coefficient a = 1.

[0034] In this embodiment, specifically, when it is detected that a certain liquid auxiliary material that has been opened has been exhausted, based on the ratio of the predicted daily demand for the liquid auxiliary material and the amount that has been consumed on the same day, as well as the ratio of the business hours that have passed on the same day to the expected business hours. For example, if it is predicted that 100L will be consumed on the same day, the expected business hours are 14 hours, and 100L of the prepared materials are consumed within 13 hours of actual business hours, then if it is predicted that the supply is unrestricted on the same day, the actual consumption will be 100÷(13÷14) = 107L. Update the predicted daily demand for the liquid auxiliary material to 107L, and further predict the consumption and remaining amount of a newly opened liquid auxiliary material until the store closes. If the expected revenue brought by the predicted consumption is greater than the procurement value of the remaining amount, it is displayed that it can be ordered; otherwise, the system displays "sold out". That is, for example, there is 1 hour of remaining business hours, and a new barrel of materials is at least 50L. If a new barrel is opened, then by the time the store closes, 7L will be consumed and 43L will remain. The value created by the consumed 7L is not enough to offset the procurement value of the remaining 43L. Therefore, although there is still 1 hour until the store closes, the system will display that the products that require such materials are sold out and no more orders will be accepted. Example:

[0035] An automatic brewing coffee machine is used to realize the self-service vending and production functions of hand-poured coffee. Customers place orders by selecting the coffee origin, flavor category, cold or hot on the screen and scanning the code for payment. After successful payment, the coffee machine controls the cup to drop and enters the production process according to the selected category, guiding the user to complete the coffee production step by step. The coffee machine provides hand-poured cup products from a total of [number of origins] origins. Each product can make [number of flavors] flavors of coffee, including Italian, American, latte, rice milk latte, coconut milk latte, as well as cold and hot drinks. To achieve the above functions, the device is designed with the following structures and functional modules:

[0036] Computer main control system;

[0037] Cup dropping device: The hand-poured cup coffee from six origins sold by the coffee machine corresponds to six different coffee cups. Each coffee cup is installed on a cup dropping device. When the corresponding sales category is generated on the computer side, it controls the cup dropping device to act and release a coffee cup onto the tabletop;

[0038] Steam water heater 1: The system includes a steam water heater that can produce 100-degree hot water at any time. When the customer presses the brewing and hot water button, the computer controls the hot water pump and the corresponding solenoid valve to produce a fixed amount of hot water through the hot water outlet to complete brewing and other productions that require hot water. The system continuously detects the hot water temperature in the water heater. If the temperature is not high enough, the order cannot be placed.

[0039] The steam water heater 1 can supply steam externally. When milk, rice milk or coconut milk needs to be frothed or heated, the computer controls the corresponding electromagnetic valve to output a certain amount of steam to complete the relevant actions.

[0040] Ice maker 2: The system includes an ice maker. When the customer orders iced coffee, the computer will control the ice maker 2 to produce a certain amount of ice to complete the production of iced coffee. The ice maker 2 is equipped with a remaining ice detection function to determine the amount of ice when ordering. If the amount of ice is insufficient, iced coffee cannot be ordered. At the same time, the ice maker 2 also has the function of dispensing cold water. When making iced American coffee, it will dispense a certain amount of cold water as required. The ice output of the ice maker 2 is controlled by the weighing method of the ice metering scale. The ice output control of the traditional ice maker is controlled by timing, but in actual use, the data error is very large, exceeding 50±%. To solve this problem, a weighing scale is added to weigh in real time when the ice is output. At the same time, the opening and closing degree of the ice output bin door is adjustable. When the ice output starts, the ice output bin door is fully opened. When the weighing scale detects that the weight loss of the ice maker 2 reaches 50% of the required amount, an instruction is issued to control the ice maker bin door to close 50%, and the ice output speed is slowed down. When the weighing scale detects that the ice output reaches 85% of the required amount, the bin door is controlled to close by 50%, and the ice output speed is slowed down again. Of course, it is necessary to ensure that the minimum opening of the ice output bin door can allow one ice particle to pass through. Continue to detect that the ice output reaches the requirement and close the bin door. This method can control the error within ±5% of the required ice output to meet the use needs.

[0041] Refrigerator 3: There are three auxiliary material bins in the refrigerator 3, namely coconut milk auxiliary material bin 4, rice milk auxiliary material bin 5, and fresh milk auxiliary material bin 6. A multi-bin mode is designed for these three materials. Three bottles of each material can be placed, and each bottle has a residual detection. Taking coconut milk as an example, the system is provided with a first two-way solenoid valve 8 and a second two-way solenoid valve 9 before the coconut milk auxiliary material pump 7. The output channel of the first two-way solenoid valve 8 is connected to the auxiliary material pump 7, one input channel is connected to one of the bottles of coconut milk, and the other input channel is connected to the outlet of the second two-way solenoid valve 9, and the second two-way solenoid valve 9 is connected to the auxiliary material pump 7. The two input ports of the solenoid valve 9 are connected to the other two coconut milk bottles respectively. The system controls which bottle to take the material from according to the remaining amount and shelf life of each bottle. This design is based on two considerations: one is that the mainstream packaging specifications on the current market are not large. Putting only one bottle will result in the need for frequent replenishment of materials. This multi-bin design can hold multiple bottles of the same material, which can effectively reduce the frequency of material replenishment; the second is that many materials need to be used as soon as possible after opening. If large-package products are customized, they will not be used up and will lead to great waste. Using small-package multiple bottles can better avoid this problem. Each time the material is replenished, the system records the replenishment time of each silo. When discharging, it is first-in-first-out according to the replenishment time. After detecting that the current silo is empty, the next silo material is automatically extracted; if it is determined that a silo material has expired, this silo is automatically skipped and the next silo material is extracted. In addition, materials can be easily adjusted for different equipment. For equipment with high output, more silos can be added and large barrels of auxiliary materials can be used. For equipment with low output, fewer silos can be used and small barrels of auxiliary materials can be used. Materials can also be easily adjusted for the same equipment in different time periods. During time periods with high demand, large barrels of auxiliary materials can be used and multiple silos can be used simultaneously. During time periods with low demand, small barrels of auxiliary materials can be used and some silos can be disabled.

[0042] There are many mature technologies for specific methods of detecting the remaining amount of various auxiliary materials, which will not be elaborated here.

[0043] The steam water heater 1 can output steam and hot water. After the hot water passes through the hot water pump, multiple outlets can be set. Figure 1 As shown in , in this example, a large hot water outlet, a small hot water outlet and a standby hot water outlet are provided, wherein the small hot water outlet is controlled by the second single-way solenoid valve 13, the standby hot water outlet is controlled by the first single-way solenoid valve 12, and the hot water is also connected to each milk foam nozzle through the control of the solenoid valve, such as being connected to the coconut milk foam nozzle 18 through the control of the fourth single-way solenoid valve 15. Taking the coconut milk channel as an example, the hot water pipeline between the coconut milk foam nozzle 18 and the fourth single-way solenoid valve 15 is also connected to an air channel through the fifth single-way solenoid valve 16, so as to introduce air into the milk foam nozzle.

[0044] At the same time, the hot water pipeline also leads to the part of each auxiliary material output pipe outside the refrigerator 3 through the two-way solenoid valve to flush it. Figure 1As shown, taking the coconut milk channel as an example, the output port of the coconut milk auxiliary material pump 7 is connected to an input port of the third two-way solenoid valve 10 through a one-way valve, and the other input port of the third two-way solenoid valve 10 is connected to the hot water pipeline. The output port of the third two-way solenoid valve 10 is connected to the coconut milk foam nozzle 18 through a pipeline, that is, the third two-way solenoid valve 10 can control whether the output port is connected to the first input port or the second input port, or is completely closed and not connected to any input port. When it is switched to be connected to the first input port, coconut milk is normally provided to the outside, and when it is connected to the second input port, it is connected to the hot water pipeline to achieve flushing of the external pipeline of the refrigerator 3. Further, a fourth two-way solenoid valve 11 is also provided on the pipeline between the third two-way solenoid valve 10 and the coconut milk foam nozzle 18. The solenoid valve 11 is preferably arranged as close to the coconut milk foam nozzle 18 as possible, the input end of the fourth two-way solenoid valve 11 is fixedly connected to the output port of the third two-way solenoid valve 10, the first output end of the fourth two-way solenoid valve 11 is connected to the coconut milk foam nozzle 18, and the second output end is connected to the sewage bucket. Therefore, when flushing the pipeline, the input end of the fourth two-way solenoid valve 11 is connected to its second output end, and the flushing waste water is discharged to the sewage bucket instead of being discharged through the coconut milk foam nozzle 18, which can improve the sensory quality of the product. Of course, the input end of the fourth two-way solenoid valve 11 is still connected to its first output end in the end, so as to flush the channel in the coconut milk foam nozzle 18, but the flushing water at this point is very little, so that a lot of cleaning water will not be discharged from the coconut milk foam nozzle 18.

[0045] The steam outlets of the steam water heater 1 are also respectively led to the milk foam nozzles through the control of the solenoid valves to meet the operation required for foaming. For example, taking the coconut milk channel as an example, the steam channel is led to the coconut milk foam nozzle 18 through the sixth single-way solenoid valve 17. At the same time, the steam channel is also connected to the small hot water outlet through the third single-way solenoid valve 14 to reheat the hot water and ensure that the hot water temperature at the small hot water outlet meets the requirements.

[0046] The working principles of other auxiliary material channels are the same and will not be described in detail.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
