However, in addition to the above-mentioned hand-brewing action of imitating hand-brewing coffee, the best effect of imitating hand-brewing coffee should be achieved by matching with different brewing processes and different brewing parameters according to the flavor of coffee that the user wants to drink, and the relevant details will be described again below.

The first control module 50 is designed and programmed to control the simulated hand coffee machine structure 100, and the first control module 50 may be a programmable controller, such as a Micro Controller Unit (MCU). In the simulated hand coffee maker configuration 100, the first control module 50 is communicatively coupled to the human interface module 20, the brewing module 30, and the brewing module 40.

After the hmi module 20 is operated by a user, a brewing instruction input by the user at the hmi module 20 generates a control signal to the first control module 50 by the hmi module 20, and then the first control module 50 controls each module or element of the simulated hand coffee machine structure 100 according to an internal preset program code to complete the brewing of coffee required by the user.

To illustrate the operation mode of the human-machine interface module 20 and how to achieve the effect of imitating hand-brewing coffee, the design of the human-machine interface module 20 and the first control module 50 is illustrated as follows:

first, the human-machine interface module 20 can take the user's desired flavor, such as American coffee, latte, and espresso as options of the human-machine interface module 20. The built-in program simulates the general process of brewing coffee by hands, such as cup warming, bean waking, primary brewing, secondary brewing, tertiary brewing …, and the like, and completes the brewing operation of brewing coffee by hands in sequence by matching with various parameters of water, such as time, temperature … and the like.

The cup warmer is an operation of warming up the coffee filter paper not filled with the coffee powder with hot water. In addition to warming, the taste of the filter paper can thereby be washed away. At this time, the first control module 50 controls the amount and time of the hot water to be discharged, and controls the hot water pouring area by the first driving module 310, the second driving module 320, the third driving module 420 …, etc.

The bean-waking means that after the coffee powder 63 is filled in the coffee filter paper, the coffee powder 63 is soaked in hot water, so that each coffee powder 63 can absorb water and be preheated, at this time, the first control module 50 also controls the amount and the water outlet time of the hot water, and the first driving module 310, the second driving module 320, the third driving module 420 … and the like are used for making the hot water fully flush all the coffee powder 63 without dripping the hot water.

As shown in fig. 4 and 6A, the water temperature, the water amount, the first brewing, the second brewing, or the third brewing are programmed in advance according to the attribute of each coffee flavor, and the first control module 50 and the second control module 60 control the corresponding elements to operate. All of the above parameters are only examples, and any parameter can be hierarchically programmed on the human-machine interface module 20 by the user. In the embodiment, the coffee filter paper container 71 is used for containing the coffee powder 73, and the first driving module 310, the second driving module 320, the third driving module 420 …, and the like are used for controlling the water outlet head 330 to move in the first direction 710 and the second direction 720, for example, and interact with the rotation direction 730 of the coffee cup 70, so that the water outlet head 330 generates the hand-simulated brewing motion 72 of rotating and lifting up and down, and the hand-simulated coffee brewing machine structure 100 can brew the hand-simulated coffee with the same effect or flavor as that of manually brewing coffee.

As shown in fig. 6A, in addition, another part of the commands inputted by the user in the hmi module 20 is generated by the hmi module 20 and provided to the second control module 60, and the second control module 60 reads the signals generated by the hmi module 20, which can execute the following steps:

reads the brewing instruction D1 of the human-machine interface module 20, and drives the second water pump 172 to supply the brewing hot water.

As shown in fig. 6B, the first temperature signal T1 of the first temperature sensor S1 is read to control the heating operation of the instant heater 180; the instant heater 180 is mainly used to rapidly provide the first stage of hot brewing water, and in general, the preset outlet water temperature Tq of the instant heater 180 is controlled, so that the heating action of the instant heater 180 can be controlled by the second control module 60 to make the outlet water temperature be 80-90 ℃.

As shown in fig. 6C, the temperature setting T0 of the human-machine interface module 20 and the second temperature signal T2 of the second temperature sensor S2 are read to control the heating operation of the brewing heater 133; the brewing heater 133 is typically a powerful heater, and the brewing heater 133 primarily heats the brewing water tank 131 to produce the water temperature most suitable for brewing.

The most suitable water temperature for brewing can be determined according to the temperature setting T0 selected by the hmi module 20, when the hmi module 20 selects a certain coffee or brewing mode, the corresponding temperature setting T0 is transmitted to the second control module 60, and the second control module 60 can set the temperature setting T0 as the optimal brewing temperature and control the brewing heater 133 to heat to the optimal brewing temperature.

As shown in FIG. 6D, the temperature setting T of the human-machine interface module 20 is read₀And a third temperature sensor S₃Third temperature signal T₃To control the third solenoid valve 163 to perform the brewing and opening action SW₁Or backwater opening action SW from backwater to the brewing water tank 131₂. Since the pipeline path between the brewing water tank 131 and the water outlet head 330 at the beginning of brewing causes a certain section of water to be discharged at the beginning, the water temperature is seriously lower, and the brewing quality is affected.

In order to ensure the temperature of the brewing water in the water outlet 330, the third temperature sensor S is used₃The temperature of the water inlet of the water outlet head 330 is detected, i.e. the third temperature signal T₃Out of the set temperature T₀When the optimal brewing temperature is reached, the third solenoid valve 163 is backwashed to open the SW₂At the moment, the water flow flows back to the brewing water tank to be heated again, and the water outlet head cannot carry out brewing operation.

And to makeThe water return is smoother, a third water pump 173 is further disposed between the third solenoid valve 163 and the brewing water tank 131, and the third water pump 173 and the third solenoid valve 163 perform the synchronous operation of water return opening. When the third temperature sensor S₃The temperature of the water inlet of the water outlet head 330 is detected, i.e. the third temperature signal T₃Has reached a set temperature T₀At the optimal brewing temperature, the third solenoid valve 163 is made to perform brewing opening SW₁At this time, the water outlet 330 can perform brewing operation.

As shown in FIG. 6E, since the amount of water brewed in each coffee is different, a flow meter 190 may be further disposed between the brewing water tank 131 and the water storage tank 121, and the second control module 60 reads the water amount setting W of the human-computer interface module 20₀The actual flow rate W of the flow meter 190 is read again as a preset value₁Comparing the actual flow W₁Water volume setting W₀At this time, the driving of the second water pump 172 is stopped to control the amount of brewing water.

Since the brewing tank 131 is used for a period of time, which often requires cleaning, the brewing tank 131 may further be provided with a drain valve 164, and when the user selects the cleaning button of the human-machine interface module 20, the second control module 60 controls the drain valve 163 to be opened, so as to perform the waste water removal operation during cleaning.
