Description

DUTCH COFFEE MAKER}

The present invention relates to a Dutch coffee extracting apparatus, and more particularly, to a sanitary Dutch coffee extracting apparatus capable of finely adjusting the amount of water dripping.

In general, Dutch coffee is not a method of pouring hot water, but rather a drop of water or room temperature water, which is slowly extracted for a long time. Generally, Dutch coffee extracts coffee over a long period of time (about 3 to 12 hours) and adjusts the taste and aroma of the coffee by changing the amount of water drip per hour (drip speed). In general, coffee extracted over a long period of time at a constant drip rate is rated as good quality coffee.

1 is an exemplary view showing an example of a conventional Dutch coffee extracting apparatus.

1, the Dutch coffee extracting apparatus 10 includes a water tank 11, a coffee storage tank 12, a coffee extract collection tank 13, and a cradle 14. As shown in FIG. Here, the water tank 11 is located at the uppermost part of the cradle 14, and the water inlet 16 is formed at the upper part. A drip amount regulating valve 15 is provided below the water tank 11. The drip amount regulating valve 15 regulates the amount of water drip by changing the cross-sectional area of the flow path under the water tank 11.

The coffee storage tank 12 is located in the lower part of the water tank 11 as a space where coffee powder is stored. Water falling through the drip amount regulating valve 15 flows into the coffee storage tank 12 and a coffee extract can be made. A lower portion of the coffee storage tank 12 may have an outlet 17 through which the coffee extract may flow. A filter 18 may be provided on the bottom of the coffee storage tank 12 to filter the coffee extract.

The coffee extract collection tank 13 is located under the coffee storage tank 12 as a container for collecting coffee extract. The holder 14 can support the water tank 11, the coffee storage tank 12 and the coffee extract collection tank 13.

However, in such a Dutch coffee extracting apparatus 10, even if the drip amount regulating valve 15 is slightly opened, water may fall down in a water stream. Further, as the amount of water in the water tank 11 is reduced, the water pressure is lowered and the dripping rate of the water is gradually reduced, so that it is difficult to maintain a constant dripping rate. In the case of opening the channel too small for extraction for a long time, Lt; / RTI > Due to such a problem, it is difficult to control the fine drip amount of water in the conventional coffee extracting apparatus 10 of the prior art.

Further, since the drip amount control valve 15 of the conventional Dutch coffee extracting apparatus 10 is not easy to separate and clean even if a foreign object is caught, it may cause hygienic problems such as contamination by foreign substances.

On the other hand, Japanese Patent Laid-Open Publication No. 10-1485771 (published on Jan. 26, 2015) discloses a Dutch coffee extractor provided with a flow controller so that the amount of drip can be finely adjusted. However, in the Dutch coffee extractor disclosed in the above document, the user adjusts the amount of water drip to adjust the amount of drip of the desired amount of water, and then places the water supply container on the liquid storage container. That is, when the flow regulator is fixed to the water supply container, the amount of water drip can not be controlled.

In addition, the flow regulator is a structure that must be manually held and adjusted by the user. Therefore, the flow regulator may be dirty or contaminated with foreign substances and harmful bacteria due to the user's surroundings, etc., and hygienic problems may occur in the coffee extract which is extracted into the water flowing through the soiled or contaminated flow regulator.
