As shown in Figure 13, the touch screen 71 displays some brewing paths for the user to choose. Each pattern button represents a brewing path. The user can click the pattern button of the brewing path that he wants to select. Proceed with brewing. The brewing path displayed on the touch screen 71 may be a preset brewing path provided by the data unit 60 or a customized brewing path. The method of generating the brewing path is not limited at all. Users can use the default brewing path, click the customized pattern button to draw and set the brewing path, or directly draw the brewing path for brewing during use. Moreover, if the user wants to draw a new brewing path, the user is not limited to drawing on the touch screen 71 or hand-drawing pad 72 of the brewing machine, but can also draw it through a mobile device (such as a mobile phone, tablet computer, notebook computer or desktop computer). computer) for path drawing.

In one embodiment, the liquid can enter a heater (not shown) outside the brewing machine 10A for preheating, so the heating devices 12a and 12b can heat the liquid to a set temperature faster. In one embodiment, the liquid supply unit 11 can be a liquid storage tank in the brewing machine 10A, and the liquid storage tank can be taken out of the brewing machine 10A. In one embodiment, the brewing machine 10A can be used with a liquid purification device or a liquid sterilization device, and can remove minerals or other Additives are added to liquids to create different liquid flavors. Furthermore, each brewing component 101, 102 only needs to be able to achieve the purpose of independent liquid discharge, and its structure is not limited. In another embodiment, for example, the pumps 13a and 13b can be disposed between the liquid supply unit 11 and the heating devices 12a and 12b. Alternatively, as shown in Figure 15, the two brewing assemblies 101, 102 can share the same heating device 12 to reduce the number of components and reduce manufacturing costs.

FIG. 16A is a schematic diagram illustrating the design of a return flow path according to an embodiment of the present invention. As shown in Figure 16A, the pump 13 is arranged between the heating device 12 and the liquid outlet 14, and the flow path from the heating device 12 to the liquid outlet 14 is provided with two solenoid valves 15a, 15b to form a flow path to the liquid outlet. The liquid 14 flows back to the return path of the heating device 12 . Specifically, when the brewing machine receives a brewing instruction, it can close the solenoid valve 15a and open the solenoid valve 15b, allowing the liquid to flow back to the heating device 12 along the pump 13 and the solenoid valve 15b to heat the pipeline and the inside of the pipeline.

In one embodiment, the liquid reflux action can continue to be stopped until the pipeline and the heating device reach the set temperature in unison, but this is not limited. After the liquid reflux action is completed, the solenoid valve 15a can be opened and the solenoid valve 15b can be closed, allowing the liquid to be released from the liquid outlet 14 to the container for brewing action. Through the design of the return path, it can be ensured that the temperature of the liquid first flowing out from the liquid outlet 14 at the beginning of each brewing is consistent with the set temperature, so as to obtain more precise liquid temperature control. The design of the return path is not limited at all. For example, as shown in Figure 16B, in another embodiment, the solenoid valve 15b can be disposed closer to the liquid outlet 14 on the flow path, so that from the pump 13 to the solenoid valve 15b, the liquid outlet More pipes on the flow path 14 are preheated, making it easier for the temperature of the liquid initially flowing out of the liquid outlet 14 to be consistent with the set temperature. Furthermore, in one embodiment, when the liquid injected into the container reaches a predetermined amount and the brewing action is completed, the pump 13 can be quickly activated to discharge the residual liquid in the pipeline to prevent the cooled residual liquid from being used next time. It enters the container during brewing, and can prevent residual liquid from dripping from the liquid outlet 14 when brewing is not carried out. It should be noted here that the solenoid valve 15 used in each of the above embodiments is only an example, and other valve bodies with the same function can also be used without limitation.

Brewing parameters include, for example, brewing path, liquid temperature, brewing liquid volume, liquid outlet flow rate, etc. For example, in brewing sequence programming A, the brewing time of the first stage is 15 seconds and the liquid flow rate is 2cc/second, and then the brewing time of the second stage is 20 seconds (as shown in Figure 18 to the third stage). Ends at 35 seconds), and the liquid outlet flow rate changes to 0cc/second (that is, the second stage is the conventional steaming (blooming) stage), the third stage ends at the 70th second time point and the water injection flow rate is 2.57cc/s, and the fourth stage ends at the 95th second time point and the water injection flow rate is 5.8cc/s. The flavor/mouthfeel of brewed drinks can be more precisely controlled through brewing sequence programming. Furthermore, multiple brewing machines (as shown in Figure 17) can use different brewing sequence programs to perform brewing actions. For example, at the same time, brewing machines 10B and 10C can use brewing sequence program A to brew black coffee. coffee, and the brewing machines 10D and 10E can use brewing sequence program B to brew latte coffee. Furthermore, multiple brewing stations composed of multiple brewing components of the same brewing machine can execute different brewing sequence programming at the same time. For example, the brewing component 101 of the brewing machine 10A can execute brewing sequence programming A and the brewing component 102 can perform brewing sequence programming B. The number and content of brewing sequence programming are not limited at all. Brewing sequence programming can be automatically recommended by the brewing machine, or the user can modify or define it through the operating interface of the brewing machine itself or the application of the mobile device. Furthermore, the brewing machines of various embodiments of the present invention can use brewing sequence programming to perform brewing.

19A and 19B are schematic diagrams illustrating a brewing machine according to another embodiment of the present invention. Please refer to Figure 19A and Figure 19B. The brewing machine 10F includes a brewing component 101 and a grinding device 120. The brewing component 101 is used to provide fluid with a set temperature and flow rate to a container 130 for brewing action. It can The architecture of each of the foregoing embodiments is adopted, so no details will be described here. The grinding device 120 is disposed above the brewing assembly 101. The grinding device 120 can grind a raw material (such as coffee beans), and the ground material (such as coffee powder) is released along a path through the outlet 122 along the grinding device 120. Debris. In this embodiment, a transmission component 140 can be used to change the distance between the outlet 122 of the grinding device and the bottom end 112 of the brewing component 101. As shown in Figure 19A, for example, when the grinding device 120 will release the ground material, the path device 20 of the brewing assembly 101 can move the liquid outlet 14 outside the release path of the ground material, and the transmission member 140 can move the entire The brewing assembly 101 moves upward so that the grinding device outlet 122 is close to the container 130 to prevent the ground material from scattering. As shown in Figure 19B, after the ground material is released into the container 130, the transmission member 140 can move the entire brewing assembly 101 downwards back to the original position. At this time, the path device 20 of the brewing assembly 101 can exit the liquid. 14 moves to the release path of the ground material (that is, directly above the container 130), and the liquid outlet 14 releases the liquid for subsequent brewing action. because Therefore, in this embodiment, when the grinding device 130 releases the ground material (FIG. 19A), the grinding device outlet 122 and the bottom end 112 of the brewing component have a first distance D1, and when the liquid outlet 14 releases liquid (FIG. 19B), the grinding device outlet 122 and the bottom end 112 of the brewing assembly have a second distance D2, and the first distance D1 is smaller than the second distance D2. In one embodiment, a scale 114 can be provided at the bottom 112 of the brewing component.

The distance between ends 112. The scale 114 can be used to accurately measure the weight of beans added by the user, and then the amount of brewing water can be automatically adjusted according to the set ratio. Alternatively, the scale 114 can also be used to accurately set the bean weight and brewing water volume simultaneously. Furthermore, as shown in FIG. 19B , in one embodiment, the brewing machine can be provided with an alignment device 150 to allow the user to easily align the center of the container 130 with the position of the liquid outlet 14 when the liquid is discharged. For example, a magnet 152 can be disposed in the scale 114 at the bottom 112 of the brewing assembly just below the position corresponding to the liquid outlet 14 when the liquid is discharged, and another magnet 154 can be disposed in the center of the bottom of the container 130.

For example, a protrusion may be provided on the scale 114 (or the bearing platform) directly below the liquid outlet 14 , and a corresponding notch may be provided in the center of the bottom of the container 130 to engage the protrusion. .

The structure of the transmission member 140 is not limited, as long as it can change the distance between the grinding device outlet 122 and the bottom end 112 of the brewing assembly (or the distance between the grinding device outlet 122 and the top of the container 130). For example, as shown in FIG. 20 , the transmission member can be a telescopic hollow pipe 142 that extends and retracts automatically or manually, and can also change the distance between the grinding device outlet 122 and the brewing assembly 101 . Furthermore, in one embodiment, the grinding device 120 can also be controlled by the user through, for example, an application on a mobile device. Furthermore, the grinding device can have the function of automatically adjusting the grinding thickness.

Through the design of each of the above embodiments, since the liquid outlet 14 is disposed on the path device 20, and the path device 20 moves the liquid outlet 14 according to at least one brewing path, the water flow pattern and path of manual coffee brewing can be simulated. Furthermore, by providing various brewing parameters through the data unit 60, the user can transparently Any brewing parameter is selected or set through the operating unit 70, and the control unit 80 can control the heating device 12 to adjust the heated water temperature, control the liquid outlet 14 to adjust the amount of water flowing out, and control the path according to the selected or set brewing parameter. The device 20 moves the path of the liquid outlet 14 so that various brewing parameters can be accurately controlled to eliminate errors and instability of manual coffee brewing. In addition, because users can brew by customizing the brewing path and brewing sequence programming, the brewed drinks can be unique. Furthermore, the brewing machine can integrate grinding devices and transmission mechanisms in various dimensions, making it more convenient for users to use.
