Description

  The present invention relates to a structure of a coffee maker that automatically extracts, and in particular, a coffee maker that is equipped with a rocking device and can achieve an effect as if it is being extracted by a human hand. In particular, the present invention relates to a coffee maker that can be extracted in hot water and completely extract the rich and sweet flavor of coffee powder.

  Generally, coffee extraction methods include siphon type, high pressure extraction type (Espresso), and drip type. The so-called siphon type is also called a vacuum filtration method, and basically consists of two glass balloons. One is placed over the other and is separated by a filter with a cloth filter. First, hot water is put into a lower glass balloon (flask), and then an upper glass balloon (funnel) covered with a filter is fixed and ground coffee powder is put. The hot water in the flask is heated by an alcohol lamp or other heat source, and when the hot water boils, the water rises through the tube by vapor pressure. At this time, the coffee powder and hot water in the funnel come into contact with each other and a stirring operation occurs, and both are mixed and become mud, and the taste and aroma of the coffee are eluted. Put out the fire when the coffee is sufficiently immersed in the water. Then, the air in the lower flask is cooled to form a vacuum state. Thereby, the coffee liquid passes through the filter and is sucked into the flask. After this, pour the coffee into a preheated cup and enjoy its unique flavor and taste.

In the so-called high pressure extraction type, first, coffee beans are ground into a fine powder having a constant grain size. This is compressed by tampering. In order to counter the pressure of hot water during extraction, the coffee powder in the filter must be packed tightly and form a blocky coffee block.
When hot water is under great pressure, it penetrates the coffee block in search of the way. If the pressure and tightness of the coffee block are consistent, all of the coffee grounds are averagely extracted into hot water and completely poured into the cup. In this way, rich Italian-style concentrated coffee is poured into a small cup. Whether or not a balanced symmetry between pressure and resistance is achieved is an indispensable element for making a rich and delicious espresso. The high pressure extraction system allows coffee powder to pass quickly through hot water at an appropriate pressure, so that the time for extracting a cup of coffee is only 25-30 seconds, saving time and cost.

  Furthermore, the drip type is, as the name suggests, a funnel placed over the container and drip. Put the filter paper into the funnel, put the ground coffee powder, and finally pour hot water into the funnel, the hot water slowly filtered and dripped into the container through the through hole at the bottom of the funnel, thus making the coffee delicious Can drown. In the filter paper drip method, coffee powder and hot water are sufficiently mixed, and then the flavor in the coffee is eluted and drip through the filter paper. This method can filter fat, protein, and poor impurities contained in the coffee, so that a refreshing coffee can be obtained.

  The most important skill of drip coffee extraction is the control of water flow size and stability. A moderate and stable water stream spirals outward from the center point of the funnel, then returns to the inside and goes back and forth. As a result, the coffee powder is uniformly extracted, and all of the rich and sweet flavor is removed. However, in the general drip-type process of extracting hot water, the operation depends on the hand of the person, and thus the experience of the person who can make coffee greatly affects the flavor of the coffee. Those who are not experienced cannot draw a circle repeatedly uniformly during extraction, so the quality of the drip coffee becomes uneven and affects the overall flavor of the coffee. The present invention provides a drip coffee maker that can be automatically mass-produced, which solves the drawback of the conventional manual coffee extraction method that a great deal of experience is an absolute factor that determines the flavor of coffee. .

The first problem to be solved by the present invention is to install a rocking device in the coffee maker, and the water in the coffee maker draws a circle by reciprocating in and out spirally from the center of the filter. By controlling the size, stability, rocking speed, and extraction temperature of the sprayed water, it is possible to achieve a dripping effect that makes a master brew, thus extracting the coffee powder quickly and uniformly, It is to provide an automatic drip extraction coffee maker that can give off a sweet and savory flavor.
The second problem to be solved by the present invention is to improve the conventional coffee extraction method, which has had a direct influence on the flavor of coffee, because the extensive experience of coffee extraction has been improved, the extracted coffee is rich and sweet It is to provide an automatic drip coffee maker that can be quickly mass-produced while retaining the flavor.
