[0001] PORTABLE APPARATUS FOR EXTRACTION FOR DUTCH COFFEE [0002]

[0001] The present invention relates to a portable still coffee extracting apparatus, and more particularly, to a portable still coffee extracting apparatus capable of extracting DUTCH COFFEE at a faster time as water supplied directly to a water storage device, The present invention relates to a Dutch coffee extracting apparatus.

In recent years, DUTCH COFFEE, a water drip type coffee which uses cold water to extract and drink coffee liquid from coffee powder for a long time has been widely used among coffee lovers.

Typical coffee is drip coffee or espresso coffee, which is a method of putting coffee powder into a lower filter and pouring hot water. However, it is characterized by the fact that coffee is extracted for a long time by dropping cold water or cold water at room temperature.

In this way, since cold water or cold water is used, the coffee aroma and flavor that can be blown away when hot water is used is extracted as it is. In other words, you can feel the subtle taste that you can not feel in hot coffee such as deep taste of coffee, rich aroma and bitter, sour, sweet.

In addition, Dutch coffee is less caffeine and can be stored for long periods. In other words, coffee caffeine occurs when it is mixed with water above 80 ℃, and because it uses cold water or cold water at room temperature, caffeine is less than coffee extracted with warm water.

However, in the conventional technique (for example, patent application No. 10-2011-0024498 "Dutch appliance and Dutch coffee making method using the same"), in the process of dropping water in the coffee powder, As the water was concentrated, the water was not easily absorbed into the whole of the coffee powder.

In addition, when water is supplied to coffee, water is supplied at room temperature. Since the temperature of room temperature may be changed according to the season or indoor heating / cooling temperature, water of constant temperature is not always supplied. There was a difficulty in doing.

In addition, since the conventional technology drips the coffee bean for a very long time, it can not be sampled at the same time as dripping, which is inconvenient because it can be added with sugar or the like depending on water or other eating habits.

Therefore, conventionally, a portable Dutch coffee extracting mechanism such as the registered patent publication No. 10-1437136 (registered on Apr. 31, 2014) has been proposed. However, it has been focused on proposing a configuration for simplifying the portable body by making the volume lighter, The problem of long manufacturing time can not be solved.

In addition, since the conventional portable Dutch coffee extracting apparatus can not be connected to a general water supply device like a water purifier, the user has to fill the cup with water and charge the coffee extracting apparatus.
