[0013] An embodiment of a coffee brewing device 1 according to the present invention will be described with reference to the accompanying drawings. In the drawings, components with the same reference numerals have the same or similar configurations. Furthermore, the present invention is not limited to the embodiment.

[0014] FIG. 1 is a diagram showing an example of the appearance of a coffee brewing apparatus 1 according to this embodiment. FIG. 2 is a diagram showing an example of the configuration of the coffee brewing apparatus 1 according to this embodiment. The coffee brewing apparatus 1 is installed in, for example, a convenience store, and provides regular coffee or decaffeinated coffee in response to instructions from a user. Hereinafter, when there is no particular distinction between regular coffee and decaffeinated coffee, they will also be referred to as "coffee." The coffee brewing apparatus 1 may be operated by a purchaser or an employee. Hereinafter, when there is no particular distinction between a purchaser and an employee, they will also be referred to as "user."

[0015] The coffee maker 1 is a device that makes coffee from coffee beans and a liquid such as hot water (hereinafter also referred to as hot water), and is capable of making one cup of coffee per brewing operation. A stage for placing a cup 100 on is provided at the bottom of the coffee maker 1, and the coffee made by the coffee maker 1 is poured into the cup 100.

[0016] The coffee maker 1 has a door 23 that opens and closes the outlet for the cup 100. This door 23 makes it possible to open and close the outlet on the front of the coffee maker 1, allowing the user to take out the coffee poured into the cup 100.

[0017] An operation unit 15 is provided above the door 23 of the coffee brewing machine 1. The operation unit 15 is configured with, for example, a touch panel, operation buttons, etc., and can display various information. The user operates the operation unit 15, such as the touch panel or operation buttons, to specify the type of coffee, such as regular coffee or failless coffee, and the coffee brewing machine 1 brews coffee according to the instruction. Details of the operation unit 15 will be described later.

[0018] As shown in Figure 2, the coffee making device 1 includes a plurality of canisters 2 for storing coffee beans, which are coffee ingredients, and a plurality of feeders 3 corresponding to the plurality of canisters 2. The plurality of canisters 2 are arranged side by side on the left and right.

[0019] The first canister 2A stores coffee beans for making regular coffee, and the second canister 2B stores coffee beans for making decaffeinated coffee. By rotating the feeder 3 corresponding to the canister 2, the coffee beans stored in the canister 2 are supplied to the mill 4. For example, by rotating the first feeder 3A, the coffee beans stored in the first canister 2A can be supplied to the mill 4.

[0020] Mill 4 is located below canister 2 and grinds the coffee beans supplied from canister 2 to a predetermined particle size by rotating feeder 3. Then, coffee brewing apparatus 1 sends the coffee bean powder (hereinafter also referred to as ground beans) ground by mill 4 to brewer unit 5, and generates a mixed liquid by adding hot water supplied from water supply tank 6.

[0021] In the brewer unit 5, the produced mixture is filtered through a paper filter to extract coffee. The coffee making apparatus 1 is provided with a grounds container 7 for disposing of the extracted decaffeinated coffee, coffee grounds after extraction, paper filters, etc. in a preliminary process 50 described below.

[0022] 2, coffee making apparatus 1 includes a controller 10 that controls the operation of coffee making apparatus 1. Controller 10 includes a control unit 11, a process management unit 12, a reception unit 13, a memory unit 14, etc. Reception unit 13 receives information from an operation unit 15 and a sensor 16.

[0023] The control unit 11 includes a processor such as a CPU, and controls the operation of the motors of the feeders 3, the motor of the mill 4, the paper filters and valves of the brewer unit 5, the pump of the water tank 6, etc. The control unit 11 may be realized, for example, by having a processor such as a CPU execute a program, that is, by software, or by hardware such as an IC, or by a combination of software and hardware.

[0024] The control unit 11 is electrically connected to the canister 2, the process control unit 12, etc., and controls the process control unit 12, which manages the process of making the type of coffee specified by the user. The control unit 11 also controls the overall operation of these units in accordance with programs and data stored in the memory unit 14, which is also electrically connected.

[0025] When the reception unit 13 receives an instruction to make, for example, regular coffee as the first type of coffee, the control unit 11 controls the process management unit 12 to perform main process 60. When the reception unit 13 receives an instruction to make, for example, decaffeinated coffee as the second type of coffee, the control unit 11 controls the process management unit 12 to perform preliminary process 50 followed by main process 60.

[0026] The process management unit 12 manages the manufacturing process of the type of coffee specified by the user via the reception unit 13, in accordance with the programs and data for managing the processes stored in the memory unit 14. The processes managed by the process management unit 12 include a main process 60 and a preliminary process 50.

[0027] Reception unit 13 receives information from operation unit 15 and sensor 16. For example, operation unit 15 is an interface or the like configured with a touch panel, operation buttons, etc., and reception unit 13 receives the type of coffee specified by the user via operation unit 15. The user may be a purchaser or an employee. Note that the type of coffee may be specified by placing cup 100 on a stage and having sensor 16 read the color or pattern printed on cup 100.

[0028] The sensor 16 can detect whether the cup 100 is placed correctly. For example, if the cup 100 is not placed within a normal range, if the cup 100 is deformed, or if the cup 100 has a lid and coffee cannot be poured into the cup 100, the sensor 16 can detect the abnormality and output an alert.

[0029] Storage unit 14 includes memories such as ROM and RAM, and stores programs for operating coffee brewing device 1. Storage unit 14 also stores recipe data for coffee that can be supplied, and programs and data for managing processes. Note that the stored programs, recipe data, etc. may be updatable via a communication medium or storage medium.

[0030] Fig. 3 is a diagram showing an example of the flow of the manufacturing process according to this embodiment, and Fig. 4 is a diagram showing another example of the flow of the manufacturing process according to this embodiment. As shown in Figs. 3 and 4, the process management unit 12 included in the coffee manufacturing apparatus 1 manages the manufacturing process including the main process 60 and the preliminary process 50.

[0031] The main process 60 is a process for producing the type of coffee specified by the user. The preliminary process 50 is a process for removing caffeine by cleaning the mill 4 and the brewer unit 5 before producing the type of coffee specified by the user to be provided to the user, for example, a process for preliminarily producing the coffee to be produced in the main process 60.

[0032] When the type of coffee instructed by the user is a first type of coffee, for example, regular coffee, the control unit 11 controls the process management unit 12 to perform only main process 60. On the other hand, when the type of coffee instructed by the user is a second type of coffee, for example, decaffeinated coffee, the control unit 11 controls the process management unit 12 to first perform preliminary process 50 and then perform main process 60. As a result, when producing decaffeinated coffee, the mill 4 and brewer unit 5 are cleaned in preliminary process 50, thereby removing a certain amount of caffeine that has adhered to them.

[0033] First, details of main process 60, which is a manufacturing process managed by the process management unit 12, will be described. Fig. 5 is a flowchart showing an example of main process 60. As shown in the figure, main process 60 includes a bean discharge process S11, a grinding process S12, a water extraction process S13, a steaming process S14, a stirring process S15, an extraction process S16, and an extraction process S17. In main process 60, the type of coffee specified by the user is produced and served to the user.

[0034] First, in the bean discharge step S11, the feeder 3 discharges the coffee beans stored in the canister 2. Here, the first feeder 3A discharges the coffee beans for making regular coffee stored in the first canister 2A.

[0035] Next, in the grinding step S12, the mill 4 grinds the coffee beans for producing regular coffee supplied from the first canister 2A.

[0036] Next, in the hot water extraction step S13, the brewer unit 5 produces a mixture from the ground coffee beans for making regular coffee supplied from the mill 4 and hot water supplied from the water supply tank 6.

[0037] Next, in the steaming step S14, the mixture is steamed for a predetermined time. During this time, the components contained in the coffee beans gradually dissolve in the hot water, producing the aroma and flavor of coffee.

[0038] Next, in the stirring step S15, the steamed mixture is stirred by a predetermined method. By stirring, the time required for extraction in the subsequent extraction step can be shortened.

[0039] Next, in the extraction step S16, the resulting mixture is filtered using a paper filter to extract regular coffee from the mixture.

[0040] Next, in a serving step S17, the extracted regular coffee is poured through a nozzle 8 into a cup 100 placed on a stage.

[0041] 6 is a diagram showing an example of the flow of liquid in this step 60. In flow F11, water is supplied from a water supply or the like to the water supply tank 6, and the water is stored in the water supply tank 6.

[0042] In flow F12, water stored in the water supply tank 6 is heated to generate hot water, which is then supplied to the brewer unit 5 for use in the hot water extraction process.

[0043] In flow F13, coffee beans ground in mill 4 and hot water supplied from water supply tank 6 are added to brewer unit 5 to produce a mixture. The mixture is filtered through a paper filter, extracted as coffee, and supplied to cup 100 through nozzle 8.

[0044] Next, details of the preliminary process 50, which is a manufacturing process managed by the process management unit 12, will be described. FIG. 7 is a flowchart showing an example of the preliminary process 50. In this embodiment, the preliminary process 50 preliminarily produces the type of coffee specified by the user to be produced in the main process 60. When the control unit 11 receives an instruction to produce decaffeinated coffee, it controls the preliminary process 50 to be performed before the main process 60. Therefore, the type of coffee specified by the user to be produced in the preliminary process 50 is decaffeinated coffee. The preliminary process 50 includes a bean discharge process S21, a grinding process S22, a hot water pouring process S23, a paper feeding process S24, and a disposal process S25.

[0045] First, the bean discharging step S21 is a step in which the coffee beans for producing decaffeinated coffee stored in the second canister 2B are discharged by the second feeder 3B. The coffee beans in the bean discharging step S21 are discharged from the same second canister 2B as the coffee beans in the bean discharging step S11 of the main step 60, which is performed after the preliminary step 50. The amount of beans used in the preliminary step 50 may be the same as the amount of beans used in the main step 60. This allows at least a portion of the programs and data for managing the steps stored in the memory unit 14 to be common between the main step 60 and the preliminary step 50, simplifying maintenance.

[0046] Next, the grinding step S22 is a step for grinding the coffee beans. The coffee beans supplied from the second canister 2B are ground in the mill 4. In the grinding step S22, the coffee powder that had been adhering to the mill 4 before the preliminary step 50 was performed is scraped out of the mill 4 by the ground coffee beans and falls into the brewer unit 5 together with the ground coffee beans.

[0047] Next, the hot water pouring step S23 is a step for extracting coffee. In the brewer unit 5, hot water supplied from the water supply tank 6 is poured onto the ground coffee beans supplied from the mill 4 to produce a mixture, from which coffee is extracted. Unlike the main step 60, the preliminary step 50 does not require steaming or stirring after pouring the hot water. The amount of hot water supplied in the preliminary step 50 may be the same as the amount of hot water supplied in the main step 60. This allows at least a portion of the programs and data for managing the steps stored in the memory unit 14 to be shared between the main step 60 and the preliminary step 50, simplifying maintenance. Furthermore, this allows for more effective cleaning of the mill 4 and the brewer unit 5, thereby removing caffeine and other contaminants.

[0048] Next, in the paper filter feeding step S24, the paper filter is fed by the paper filter feeding device and the extraction grounds on the paper filter are disposed of in the grounds container 7. In order to discard the powder and dirt remaining on the paper filter and send out a new paper filter, the paper filter with the remaining powder and dirt is sent to the side opposite the coffee serving side, and the coffee making device 1 cuts off the paper filter at predetermined intervals, and the paper filter with the remaining powder and dirt is disposed of in the grounds container 7.

[0049] Next, in a disposal step S25, the decaffeinated coffee extracted in the preliminary step 50 is disposed of in the dregs container 7. When the decaffeinated coffee is disposed of in the dregs container 7, any caffeine and other substances remaining in the mill 4 and brewer unit 5 before the preliminary step 50 is performed are also disposed of in the dregs container 7 together with the decaffeinated coffee. This completes the preliminary step 50, and the control unit 11 controls the next step, the main step 60, to be performed.

[0050] 8 is a diagram showing an example of the flow of liquid in the preliminary process 50. In a flow F21, water is supplied from a tap to the water supply tank 6, and the water is stored in the water supply tank 6.

[0051] In flow F22, hot water is generated by heating water stored in water supply tank 6, and a predetermined amount of hot water is supplied to brewer unit 5.

[0052] In flow F23, the decaffeinated coffee produced in the preliminary process 50 is discarded from the brewer unit 5 into the dregs container 7.

[0053] As described above, in the preliminary process 50, decaffeinated coffee is produced, which is to be produced in the main process 60 immediately after the preliminary process 50. Therefore, the caffeine and other substances remaining in the parts due to the previous production of regular coffee in the main process 60 can be disposed of in the grounds container 7 together with the decaffeinated coffee extracted in the preliminary process 50.

[0054] As a result, residual caffeine and other substances remaining on the parts can be disposed of in the dregs container 7 more effectively than when washing with hot water or the like, and the decaffeinated coffee produced by the main process 60 immediately after the preliminary process 50 is less likely to contain residual caffeine and other substances remaining on the parts than before the preliminary process 50 was carried out.

[0055] In addition, since the decaffeinated coffee to be served in this step 60 is less likely to be mixed with, for example, regular coffee, the decaffeinated coffee to be served in this step 60 will have a higher purity, improving the quality of the decaffeinated coffee.

[0056] 9 is a diagram showing an example of process control of the present invention. The operation of the coffee making device 1 will be described while explaining the process control processing.

[0057] First, in step S31, the user operates the operation unit 15 of the operation panel of the coffee making device 1 to specify the type of coffee, such as regular coffee or decaffeinated coffee, and the reception unit 13 receives the type of coffee specified by the user.

[0058] In step S32, the control unit 11 determines whether the type of coffee received is regular coffee or decaffeinated coffee.

[0059] When the instructed type of coffee is regular coffee (step S32: No), the control unit 11 controls the process management unit 12 to skip the preliminary process 50 and perform the main process 60.

[0060] If the specified type of coffee is decaffeinated coffee (step S32: Yes), the control unit 11 controls the process management unit 12 to perform the preliminary process 50 before the main process 60.

[0061] In step S33, the control unit 11 controls the process management unit 12 to perform the preliminary process 50. The liquid decaffeinated coffee produced in the preliminary process 50 is discarded into the grounds container 7. This allows the caffeine and other substances remaining in the mill 4 to be discarded together with the decaffeinated coffee.

[0062] In step S34, the control unit 11 performs this step 60 by controlling the process management unit 12 to perform this step 60. The liquid produced in this step 60 is poured through the nozzle 8 into a cup 100 placed on a stage.

[0063] According to the coffee making apparatus 1, coffee making method, and program of the present invention configured as described above, even when a single coffee making apparatus 1 is used to make both regular coffee containing caffeine and decaffeinated coffee, it is possible to provide various types of coffee while preventing unintended contamination with caffeine.

[0064] The program according to the present invention can be installed or downloaded into an information processing device through various recording media such as optical disks such as CD-ROMs, magnetic disks, and semiconductor memories, or by downloading via a communication network or the like.

[0065] In this specification, the term "unit" does not simply mean a physical component, but also includes cases where the functions of that component are realized by software. Also, the functions of one component may be realized by two or more physical components, or the functions of two or more components may be realized by one physical component.

[0066] The above-described embodiments are intended to facilitate understanding of the present invention and are not intended to limit the present invention. The elements of the embodiments, as well as their arrangement, materials, conditions, shapes, sizes, etc., are not limited to those illustrated and can be modified as appropriate. Furthermore, configurations shown in different embodiments can be partially substituted or combined with each other.

[0067] For example, in the above-described embodiment, coffee beans have been described as an example of a bean-shaped raw material, but the bean-shaped raw material of the present invention may be beans other than coffee beans. Furthermore, the first coffee material may be coffee beans obtained by roasting green beans, or may be coffee powder obtained by pre-grinding roasted coffee beans. The second coffee material may be decaffeinated coffee beans obtained by roasting green beans, or may be decaffeinated coffee powder obtained by pre-grinding roasted decaffeinated coffee beans.

[0068] Furthermore, in the above-described embodiment, coffee brewing apparatus 1 has canister 2A that stores coffee beans for making regular coffee and corresponding feeder 3A, and canister 2B that stores coffee beans for making decaffeinated coffee and corresponding feeder 3B, but the configuration and number of canisters 2 and feeders 3 are not limited to the example shown in the figures, and for example, there may be two or more canisters 2 and feeders 3. Furthermore, water supply tank 6 can produce hot water by heating water, and although the following description will be given using hot water as the liquid supplied from water supply tank 6, the liquid supplied is not limited to hot water and may be water.

[0069] In addition, the preliminary process 50 may be configured to perform each of the processes included in the preliminary process 50 using the materials used in the main process 60. For example, the beans used in the preliminary process 50 are beans stored in the same canister 2 as those used in the main process 60.

[0070] As a result, it is not necessary to prepare ingredients that are only required in the preliminary process 50, which reduces the effort required for maintenance such as replenishing ingredients. In addition, the internal space of the coffee making device 1 can be used more effectively.

[0071] The type of coffee brewed by the coffee brewing apparatus 1 and specified by the user is poured into the cup 100 through the nozzle 8. The nozzle 8 ejects the type of coffee brewed and specified by the user downward. The coffee brewing apparatus 1 may be equipped with a plurality of nozzles 8, and valves that manage the plurality of nozzles 8 may be controlled by the control unit 11.

[0072] For example, when the coffee maker 1 makes regular coffee, the coffee is poured into the cup 100 through the first nozzle 8A. When the coffee maker 1 makes decaffeinated coffee, the coffee may be poured into the cup 100 through the second nozzle 8B.

[0073] By using the multiple nozzles 8 as described above, various types of coffee can be provided while preventing residual caffeine in the nozzles 8 from being mixed in, even when the coffee making device 1 is used to make both regular coffee containing caffeine and decaffeinated coffee without caffeine.

[0074] Furthermore, the amount of beans discharged in the bean discharge step S21 may be less than the amount of beans used in the main step 60. This allows for saving beans. For example, a predetermined amount of beans less than the amount of beans used in the main step 60 may be used in the preliminary step 50. Similarly, the amount of hot water supplied in the hot water pouring step S23 may be less than the amount of hot water used in the main step 60. This allows for saving hot water. For example, a predetermined amount of hot water less than the amount of hot water used in the preliminary step 50 may be used. As a result, the amount of decaffeinated coffee, etc. discarded in the dregs container 7 can be reduced, and the time required for the entire preliminary step can be shortened. Note that the predetermined amount of beans and the predetermined amount of hot water used in the preliminary step 50 may be constant, regardless of the amount of beans and the amount of hot water used in the main step 60.

[0075] As a result, the amount of liquid produced in the preliminary process 50 that flows into the dregs container 7 is reduced, reducing the maintenance effort required for the dregs container 7. The amount of beans used in the preliminary process 50 can be adjusted by changing the program and data that manage the process stored in the memory unit 14.

[0076] As a method for controlling the process change, it is preferable that the process be changed automatically by the control unit 11, but various other methods can also be adopted, such as manually changing the process.

[0077] If the coffee ingredients stored in the multiple canisters 2 are coffee powder or instant coffee, the mill 4 may be omitted. [Explanation of symbols]
