Description

DUTCH COFFEE MAKER}

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

Dutch coffee is not a method of pouring hot water, but a coffee made by slowly dropping cold water or room temperature water dropwise for a long time.

A conventional Dutch coffee extracting apparatus 10 is shown in FIG. 1 attached hereto. The coffee extracting apparatus 10 comprises a water tank 11, a coffee storage tank 12, a coffee extract collection tank 13, a cradle 14 and a drip amount regulating valve 15. The water tank 11 is located at the top of the cradle 14 and has a water inlet 16 at the top and a flow path and a drip amount control valve 15 at the bottom. The drip amount control valve (15) adjusts the water drip amount by changing the flow path area under the water tank (11). The coffee storage tank 12 is a space in which the coffee powder is stored and is located in the lower part of the water tank 11. A filter 17 for filtering the peach extract is formed on the bottom surface. The coffee extract collection tank 13 is located under the coffee storage tank 12 as a container for collecting the extracted coffee. The water tank 11, the coffee storage tank 12 and the coffee extract collection tank 13 are supported by a holder 14.

In the conventional Dutch coffee extracting apparatus 10, coffee is extracted while the water slightly falling from the water tank 11 passes through the coffee powder stored in the coffee storage tank 12, and the extracted coffee is supplied to the coffee extract collection tank 13 Gathered.

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). Generally, coffee extracted over a long period of time at a constant drip rate is rated as good quality coffee.

The conventional Dutch coffee extracting apparatus 10 adjusts the amount of dripping water through the drip amount adjusting valve 15, which is a limitation point that it is possible to adjust the drip amount to some extent but it is difficult to finely control the amount. Generally, even if the valve 15 is slightly opened, the water drops down as a water stream, and the user gradually adjusts the amount of drip by locking the valve. In this case, there is a problem that a certain amount of water is flowed for the first time. In addition, when the amount of water in the water tank 11 is decreased, the water pressure is lowered so that the water dropping rate is gradually reduced, so that it is difficult to maintain a constant dripping rate. In the case of opening the water flow path too small for long time extraction, There is a problem in that it is stopped by a floating body or the like. Further, although the drip amount control valve 15 has a structure in which the foreign matter can be easily gripped, it is difficult to separate and clean the drip amount control valve 15, and when it is used continuously, hygienic problems such as contamination due to foreign matter may occur.
