Subsequently, the user evaluation step (S130) in which the user evaluates the taste of the extracted drip coffee is performed. In the user evaluation stage, the user evaluates the taste of drip coffee such as sweet, bitter, sour taste, soft aroma, aroma such as miscellaneous taste, dark taste, concentration such as light taste, and color such as light brown and dark brown. Will do.

If the user's evaluation is not good (No) in the user evaluation step (S130), it returns to the drip recipe setting step (S110). When returning to the drip recipe setting step (S110), the drip coffee extraction test step (S120) is again performed by modifying the extraction parameters.

If the user's evaluation is good (Yes) in the user evaluation step (S130), the user-optimized drip recipe storage step (S140) of storing the drip recipe as a user-optimized recipe suitable for the user's preference proceeds.

In the storing of the user-optimized drip recipe (S140), a recipe optimized for the user may be stored according to the taste evaluation of the user. Accordingly, the automatic drip coffee machine can always consistently implement a taste customized to the user's preference. Since the automatic drip coffee machine can store various recipes, it is possible to apply an appropriate drip recipe according to various beans, and several people can make drip coffee with their own drip recipe.

After the user-optimized drip recipe storage step (S140), the drip recipe sharing and development step (S150) may be performed. The drip recipe sharing and development step S150 may be a step of developing a user-optimized drip recipe by sharing a drip recipe of another user and/or a drip recipe of another automatic drip coffee machine.

The database (DB) accumulation and software (SW) upgrade step (S160) may be a step of accumulating a drip recipe obtained through recipe sharing between machines and users in a database and upgrading the drip recipe. Subsequently, a drip recipe setting step (S110), a drip coffee extraction test step (S120), a user evaluation step (S130), and a user optimized recipe storage step (S140) may be repeated using the upgraded user-optimized drip recipe.

A step (S170) of selecting any one selected from among a plurality of previously stored user-optimized recipes as a basic drip recipe is performed. In other words, the basic drip recipe selection step S170 may be a step of inputting any one selected from the stored user-optimized recipes as the basic drip recipe of the automatic drip coffee machine. Subsequently, a drip coffee extraction step (S180) of extracting drip coffee using a basic drip recipe is performed. Drip coffee is extracted through the drip coffee extraction step (S180).

The user-optimized drip recipe upgraded in the database accumulation and software upgrade steps can be reflected in the user drip recipe by feeding back to the user terminal. As described above, the user terminal may be connected to the system user terminal through a system communication network to receive feedback of order information input to another automatic drip coffee machine.

After the user terminal order information input step (S162), a user drip recipe distribution step (S164) of distributing the user drip recipes for each automatic drip coffee machine is performed. In the case of a plurality of user drip recipes, each user drip recipe is distributed and delivered to each automatic drip coffee machine.

After the user drip recipe distribution step (S164), a basic drip recipe selection step (S170) of selecting any one selected among the user drip recipes as a basic drip recipe is performed. After the drip coffee extraction step (S180), the drip extraction database accumulation step (S190) of accumulating drip extraction data in the database is performed, and the drip extraction data is fed back to the user terminal. The drip extraction data may include the amount of beans used, customer preference, coffee bean condition, and machine condition.

In the automatic drip coffee manufacturing method as described above, the drip recipe, the user optimized drip recipe, the user drip recipe, and the basic drip recipe may be controlled by a user terminal or a system user terminal connected to the automatic drip coffee machine through a communication network or a system communication network.
