Description

커피머신{coffee machine}Coffee machine

본 발명은 시럽 등의 액상첨가물을 자동으로 공급하는 기능을 갖는 커피머신에 관한 것이다.The present invention relates to a coffee machine having a function of automatically supplying liquid additives such as syrup.

일반적으로, 자동판매기를 통해 판매되는 즉석음용 커피는 냉동건조된 커피분말을 주원료로 하고, 이에 프림, 설탕 등을 선택적으로 혼합하여 만들게 된다.In general, instant drink coffee sold through the vending machine is made of a freeze-dried coffee powder as the main raw material, and selectively mixed with prim, sugar and the like.

이러한, 냉동건조 커피분말을 이용하여 만들어진 커피는 맛과 향이 커피원두를 갈아서 우려내는 이른바 원두커피에 비해 크게 떨어진다는 단점이 있었다.Such, coffee made using a freeze-dried coffee powder had a disadvantage that the taste and aroma fall significantly compared to the so-called coffee beans brewed by grinding coffee beans.

따라서, 맛과 향이 살아있는 원두커피를 즐기기 위해서는 가정에서 직접 커피메이커를 이용하여 커피를 만들어 마시거나 원두커피 전문점 등을 이용하였는 바, 가정에서 주로 사용하는 사이펀드롭식 커피메이커를 이용하여서는 커피향이 농축된 에스프레소와 같은 진한커피를 만들 수 없기 때문에 다양한 형태의 원두커피를 즐길 수 없으며, 커피전문점에서는 가격이 비싸기 때문에 부담없이 커피를 즐기기에는 무리가 있다는 문제점이 있었다. Therefore, in order to enjoy coffee beans with a rich taste and aroma, coffee makers made coffee using home-made coffee makers or used coffee bean specialty stores, and coffee flavors were concentrated using siphondrop-type coffee makers used at home. There is a problem that you can not enjoy a variety of types of coffee beans because you can not make a dark coffee, such as espresso, coffee shops because the price is expensive.

그러나, 최근에는 커피원두를 압착하여 커피원액을 추출하는 압착식 원액추출기를 내장하여 편리하게 원두커피를 음용할 수 있도록 하는 커피머신이 안출되어 공급됨으로써 보다 쉽게 다양한 형태의 고급 커피를 즐길 수 있게 되었다.However, in recent years, a coffee machine for squeezing the coffee beans and extracting the coffee solution is provided, allowing the user to conveniently drink coffee beans. .

이와 같은 커피머신은 원액추출기에서 추출되는 고농도의 커피원액에 온수를 혼합하여 음용에 적합한 정도로 희석된 커피를 공급하게 되는데, 커피를 즐기는 기호가 사람마다 다른 만큼, 커피원액과 혼합되는 온수의 약을 조절하여 취향에 맞는 농도의 커피를 즐길 수 있게 된다.The coffee machine mixes hot water with a high concentration of the coffee extract extracted from the stock extractor and supplies coffee diluted to a suitable level for drinking. The amount of hot coffee mixed with the coffee solution is different depending on the preference for coffee. By adjusting, you can enjoy coffee of the concentration that suits your taste.

한편, 커피머신의 종류에 따라서는 커피원액에 설탕이나 분말프림 등의 첨가물이 선택적으로 첨가되도록 하여 다양한 종류의 커피가 제공되도록 함으로써 그 편의성을 높인 것들도 있다.On the other hand, depending on the type of coffee machine is added to the additives such as sugar or powder prim in the coffee solution is optionally so that various kinds of coffee is provided to increase the convenience.

그런데, 이러한 종래기술에 있어서, 커피원액에 첨가물을 첨가하는 장치는 분말커피를 사용하는 커피자동판매기의 구성으로서 이미 일반화된 것인데, 첨가물 공급장치는 분말형태의 첨가물을 저장하는 용기와, 용기의 토출구를 선택적으로 개폐하는 개폐장치를 포함하여 이루어져 있다.By the way, in this prior art, the apparatus for adding an additive to the coffee stock solution has already been generalized as a constitution of a coffee vending machine using powder coffee, and the additive supply apparatus includes a container for storing an additive in powder form, and a discharge port of the container. It consists of a switchgear for selectively opening and closing the.

따라서, 종래의 첨가물 공급장치에 의하면 개폐장치가 선택적으로 정해진 시간만큼 개방되고 용기에 저장된 분말형태의 첨가물이 일정량만큼 아래로 흘러내려 커피원액에 투여됨으로써 다양한 종류의 커피가 만들어지게 되는 것이다.Therefore, according to the conventional additive supplying device, the opening and closing device is selectively opened for a predetermined time, and the additives in the form of powder stored in the container are flowed down by a certain amount to be administered to the coffee stock solution to make various kinds of coffee.

그러나, 이러한 종래기술에 의하면 분말형태의 첨가물을 사용하는 특성상 커피에 투여된 첨가물이 제대로 용해되지 않아서 커피의 맛과 향이 저하되는 결과를 초래하는 경우가 빈번하다는 문제점이 있다.However, according to the prior art, the additives administered to the coffee do not dissolve properly due to the characteristics of using the additive in the form of powder, which often results in a decrease in the taste and aroma of the coffee.

또한, 분말형태의 첨가물을 효과적으로 투여하기 위하여서는 투입구가 아래로 향하는 이른바 도립(倒立)방식의 저장용기가 사용되어야 하고, 투입구를 개폐하기 위한 정밀한 개폐장치 역시 갖추어져야 하기 때문에 커피머신 전체의 구성이 복잡해짐으로써 유지관리상의 번거로움이 커지고, 제품의 가격 또한 비싸진다는 문제점이 있다. In addition, in order to effectively administer the additive in the form of powder, a so-called inverted storage container with an inlet facing downward should be used, and a precise opening and closing device for opening and closing the inlet should also be provided, so that the whole coffee machine has a structure. There is a problem that the complexity is complicated to maintain, the price of the product is also expensive.
