Definitions
- the present invention relates to a beverage extraction device for luxury products such as coffee.
- a drip coffee extractor is known as a beverage extraction device that extracts hot coffee by dropping it into powdered coffee. If this apparatus is used, coffee can be poured out by putting an appropriate amount of coffee powder in filter paper and pouring hot water from above.
- This coffee extractor includes a container having a spout and a steam port, a dropping unit for dropping coffee into the container, and a steam supply mechanism.
- the water vapor supply mechanism supplies water vapor to the inside of the container through the water vapor port of the container, and further flows into the coffee powder in the dropping unit through the spout. Thereby, the temperature at the time of steaming coffee powder is kept high.
- This invention is made
- the subject is supplying the hot water and the supply of water vapor
- a beverage extraction apparatus is as follows.
- a water storage section for storing water;
- a heating means for heating the water in the water container;
- a hot water guiding path for heating the water in the water containing part to a first temperature and leading the hot water to a favorite product;

Since the inlet of the hot water guiding path is lower than a predetermined level, hot water can be always supplied toward the nozzle. Further, since the steam guide path is higher than a predetermined level, it is possible to prevent liquid water from entering the steam guide path. Only the vapor evaporated from the liquid surface can enter through the inlet of the steam guide path.
- the hot water guiding path and the steam guiding path are preferably arranged concentrically. By arranging them concentrically, a limited space can be used effectively.
