Description

드립커피머신{automatic drip coffee machine}Automatic drip coffee machine

본 발명은 원두커피가 가지고 있는 고유의 맛을 추출하기 위한 것으로, 본래 핸드드립(hand-drip) 커피의 전형적인 추출방식이 가지고 있는 단점인 맛의 편차를 없애고 추출자의 숙련도와 관계없이 정밀하게 커피를 추출할 수 있는 획기적인 방법이다.The present invention is to extract the intrinsic taste of the coffee beans, eliminating the variation in taste, which is a disadvantage of the typical extraction method of the original hand-drip coffee and precisely regardless of the skill of the extractor It is a breakthrough way to extract.

원두커피 고유의 풍부한 커피 맛을 즐기려면 핸드드립이라는 방법으로 커피를 추출하게 된다. 이 방법은 도 1에서와 같이 분쇄된 커피를 담는 호퍼(4)와 호퍼에 여과지(3)를 넣고 그곳에 담긴 분쇄커피에 물을 부어서 통과한 추출물을 담는 용기인 서버(5)로 구성된다. 위와 같은 구성으로 추출할 때, 원하는 용량의 분쇄된 커피를 여과지를 포함한 호퍼에 담고 커피 뜸들이기(불림)와 1차 추출, 2차 추출 등으로 필요량을 추출하게 된다. 이 과정에서 추출자는 주전자를 이용하게 되는데, 주전자의 꼭지(6)가 제품마다 제각기 다르고 분쇄커피에 물을 붓는 과정에서도 일정한 물줄기의 굵기로 붓는 것은 숙련자라 하여도 쉽지 않은 과정이다. 추출자의 숙련도와 감각에 따라서 여과지에 담긴 커피가 많은 부분(1)과 적은 부분(2)에 물을 부어 뜸들이는 시간, 물줄기의 굵기와 낙차의 강도, 물의 온도와 물의 양에 따 라 커피 맛에 변화가 생기며 우량품종의 커피콩이라 할지라도 여러 과정에서 약간의 조절에 실패하면 그 고유의 풍미가 떨어지는 문제점이 발생하게 된다.If you want to enjoy the rich coffee flavor of coffee beans, you can brew coffee by hand drip. This method consists of a hopper (4) containing crushed coffee and a server (5) which puts the filter paper (3) in the hopper and a container containing the extract passed by pouring water into the ground coffee contained therein. When extracted in the above configuration, the crushed coffee of the desired capacity is placed in the hopper containing the filter paper, and the required amount is extracted by steaming (called) coffee, primary extraction, secondary extraction and the like. In this process, the extractor uses a kettle, and the taps (6) of the kettle are different for each product, and even pouring water into the crushed coffee is not easy even for the skilled person. Depending on the skill and sensation of the extractor, the coffee flavor in the filter paper depends on the amount of time it takes to pour water into the large (1) and the small (2) portions of the filter paper, the thickness of the stream and the strength of the drop, the temperature of the water and the amount of water. Even if the coffee beans of the high quality varieties fail to adjust slightly in various processes, the problem of inherent flavor falls.

또 기계적으로 일정한 굵기의 물줄기로 추출한다 하더라도, 분쇄커피가 담긴 호퍼의 모양은 깔때기 모양이어서 테두리에 가까운 부분은 커피가 적게 쌓이고 가운데 부분의 깊은 곳은 커피가 많이 담기게 되는데, 이를 고려하지 않고 일정한 굵기의 물을 부어 추출하면 호퍼에 담긴 커피가루가 얇은 부분은 과다 추출되고 커피가 많은 부분은 적절하게 추출되지 않는 문제점이 있다.In addition, even if mechanically extracted with a constant thickness of water, the shape of the hopper containing the crushed coffee is a funnel shape so that the area near the rim has less coffee and the deep part of the center contains a lot of coffee. If you pour the thickness of the water is extracted when the thin portion of the coffee powder in the hopper is overextracted, there is a problem that a lot of coffee is not properly extracted.

핸드드립 추출방식은 숙련자라 하더라도 순간적인 실수로 인해 커피 맛이 제대로 추출되지 않는 일이 발생하며, 추출자가 직접 손으로 물을 따르는 과정에서 커피가루의 많고 적음에 따른 물의 양 조절 또는 물줄기의 굵기, 물의 낙차, 온도 등 여러 요소를 추출자의 감각에 의존하기 때문에 커피가 가지고 있는 풍미와 본질적인 맛을 제대로 살리지 못하는 문제점이 있다.Even if you are an experienced hand drip extraction method, coffee taste is not extracted properly due to instant mistakes.In the process of extracting water by hand, the amount of water or the thickness of the water, Because of the factors such as drop of water, temperature, etc. depending on the extractor's sense, there is a problem that the flavor and intrinsic taste of the coffee is not properly utilized.

본 발명은 원두커피 추출에 있어서, 본체 내부에 장착된 물탱크에서 배출되는 적정온수가 타원형을 가진 최종 분사장치의 미세한 구멍을 통해 커피가 담긴 호퍼에 분사하는 장치. 이 과정에서 커피량이 적은 호퍼 테두리 바깥부분은 미세하게 공작된 구멍을 통해 물을 분사하고, 커피량이 많은 가운데 부분은 테두리 부분보다 더 확장된 구멍을 통해 물을 분사하는 드리퍼 장치. 이 타원형 드리퍼의 미세한 분 사장치가 자리하는 바깥 테두리 부분에 물을 공급하는 급수관과 이보다 확장된 분사장치가 자리하는 중심부에 물을 공급하는 급수관이 각각 조직된 구동수단과 분사장치. 상기 드리퍼가 기계 본체 내부에 있다가 추출자의 작동시에 전면으로 돌출하여 물 분사 후 본래의 위치로 후퇴하는 구동수단의 특성을 가진 드립커피제조기.The present invention is a device for injecting coffee in the hopper containing coffee through the fine hole of the final injector having an elliptical in the coffee beans extraction, the water discharged from the water tank mounted inside the main body. In this process, the outer part of the hopper edge where the amount of coffee is small is sprayed through the finely machined hole, and the middle part where the amount of coffee is sprayed through the hole which is extended more than the edge part. A drive means and an injector, each of which comprises a water supply pipe for supplying water to the outer rim of the elliptical dripper, and a water supply pipe for supplying water to the center of the expanded injector. A drip coffee maker having a characteristic of a drive means in which the dripper is inside the machine body and protrudes to the front during the operation of the extractor and retracts to its original position after water injection.

커피고유의 완벽한 맛을 즐기고 싶지만 많은 시간을 들여 섬세하게 숙련되지 않으면 양질의 커피를 즐길 수 없었다. 하지만 핸드드립 방식의 전통적인 방법을 유지하면서도 더욱 섬세한 물의 분사로 숙련자 이상의 커피를 추출할 수 있게 되고, 핸드드립의 장점인 커피를 추출하면서 즐기는 후각(향)과 시각적인(커피의 부풀기와 거품) 효과도 그대로 즐길 수 있어서 누구나 양질의 커피를 즐길 수 있다.I wanted to enjoy the perfect flavor of the coffee, but I couldn't enjoy good quality coffee without spending a lot of time and skill. However, while maintaining the traditional method of the hand drip method, it is possible to extract coffee more than the expert by using more delicate water spray, and the smell and visual (coffee swelling and foaming) effect enjoyed while extracting the coffee which is the advantage of the hand drip. Everyone can enjoy high quality coffee.

본 발명의 내용을 첨부한 도면을 이용하여 상세히 설명하면 다음과 같다.The details of the present invention will be described below with reference to the accompanying drawings.

First, put the coffee powder in the hopper to match the desired amount of coffee extraction and steaming so that the coffee powder can be extracted well, pour enough water so that the water does not fall into the outlet under the hopper to steam the appropriate time. The next step is to brew a hot water kettle and pour water spirally from the center of the coffee powder. When the water reaches the top of the hopper, stop pouring and repeat pouring again. This process leads to the first extraction and the second extraction. The characteristics of the hopper (4) in this device is a funnel shape so that the coffee powder contained in the hopper has a thin thickness of the coffee powder at the edge (2), and the coffee powder at the center (1) is thickly stacked. In this state, the hand drip is prepared with hot water at an appropriate temperature to brew a coffee rich in flavor, pour enough water in the center part, and pour less water in the rim part so that the amount of coffee is appropriate for the ratio of water. Can be. In full-scale extraction, the thickness of the water stream must be constant so that the whole coffee can be extracted evenly. If it is not constant, the coffee in the place where the coarse and large amount of water is poured melts up to the taste of the coffee ingredients at once. Phenomenon not extracted However, in this process, there is a change in the steaming time, the amount and temperature of the water, the thickness of the water poured in the kettle according to the skill of the extractor, even if the coffee of the same product causes the flavor of the coffee to change depending on the extractor.
