2. Description of the Related Art As a conventional water purifier, there is known a water purifier having a structure attached to a water tap as shown in FIG. 5 in order to remove residual chlorine and organic substances contained in tap water. This water purifier is provided with a flow path 2 through which tap water flows in the water purifier main body 1 and is equipped with activated carbon 3 in the middle of the flow path 2, and residual chlorine and organic substances contained in the tap water due to physical adsorption of the activated carbon 3. Etc. were to be removed.

On the other hand, in the cold coffee extractor shown in FIG.
Water is stored in the water container 4, and the regulating valve 5 is adjusted to drop the water little by little onto the coffee powder 7 in the filtration chamber 6. Then, while passing between the coffee powders 7, the coffee component is extracted and dropped into the glass container 8 as a coffee liquid. In this method, the coffee liquid to be extracted uses water purified by the water purifier or the like, since the taste may be deteriorated due to residual chlorine and organic substances contained in the water contained in the water charged into the water container 4. Was.

PROBLEM TO BE SOLVED BY THE INVENTION In the above-mentioned watered coffee extractor, the taste of the resulting coffee was improved or worsened by residual chlorine and organic substances contained in the water to be charged. For this reason, water was passed through a water purifier to remove residual chlorine and organic substances in the water, so that water with a good taste was obtained.

In the water purifier used above, the physical adsorption of the activated carbon 3 is used. Since the physical adsorption amount of the activated carbon 3 is proportional to the flow rate and the amount of the activated carbon 3, in order to obtain sufficient water purification, There was a problem that a large amount of activated carbon 3 was required and the cost increased.

The present invention is intended to solve such a problem, and it is an object of the present invention to provide a dashi coffee extractor capable of removing residual chlorine and organic substances contained in tap water and the like with a relatively small amount of activated carbon to obtain a delicious dashi coffee. Things.

Means for Solving the Problems To achieve the above object, the water brew coffee extractor of the present invention comprises a water container for storing water, a flow control device provided near an outlet of the water container, and the flow control device. A filtration chamber in which water adjusted to a small amount is dropped and coffee is extracted, and a container containing activated carbon provided with a heating device is provided between the flow control device and the filtration chamber.

According to the above-described configuration, the water sent into the filtration chamber where coffee is extracted is removed, and the residual chlorine and organic substances in the water are removed by activated carbon. A delicious coffee liquid can be obtained because chemical change of unnecessary components can be reduced.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a sectional view of a brewed coffee extractor showing an embodiment of the present invention. In the figure, reference numeral 9 denotes a water container for storing water, and a flow controller is provided at an outlet at a lower portion of the water container 9.
Equipped with 10. 11 is a water purification container, which contains 12 activated carbons. At the bottom of the water purification container 11, a mesh net 13 having a mesh size smaller than that of the activated carbon 12 is used. The water purification container 11 is detachable, and a filtration chamber 14 for charging and extracting coffee 15 is provided below the water purification container. Reference numeral 16 denotes a coffee container for retaining the coffee liquid extracted in the filtration chamber 14.

Next, the operation of the above configuration will be described. Water container 9
The water in the water container 9 is passed by a small amount little by little by the flow rate regulator 10. All the water that is squeezed to a very small amount by the flow rate regulator 10 and temporarily passes through the activated carbon 12 in the water purification container 11. The water that has accumulated in the water purification container 11 passes through the activated carbon 12 because the bottom of the water purification container 11 is a mesh net 13 and drops onto the coffee 15 in the filtration chamber 14, and the extracted coffee is extracted because the coffee is extracted. The liquid accumulates in the coffee container 16. What should be noted here is the speed of water passing through the water purification container 11. Since the speed of the water passing through the water purification container 11 is reduced to a very small amount by the flow rate regulator 10 and becomes very slow, even if the amount of the activated carbon 12 in the water purification container 11 is small, the water purification action is sufficiently performed.
Therefore, coffee can be extracted with water from which residual chlorine and organic substances have been removed.

FIG. 2 is a brewing coffee extractor capable of heating dripping water according to another embodiment of the present invention. In the figure, reference numeral 17 denotes a water container for storing water, and an outlet at a lower portion of the water container 17 is provided with a flow controller 20. Reference numeral 19 denotes an underwater heater, which is turned on and off by a temperature controller 18 which can keep the temperature of the heated water in the flow controller 20 constant. 21 is a water purification container, which contains 22 activated carbons. At the bottom of the water purification container 21, a mesh net 23 having a mesh size smaller than the particle size of the activated carbon 22 is used. Under the above-mentioned water purification container 21, coffee 25
Is equipped with a filtration chamber 24 for extracting water. 26 is a coffee container for storing the coffee liquid extracted in the filtration chamber 24.

Next, the operation of the above configuration will be described. Water container 17
And the water in the water container 17 is passed by a small amount by the flow controller 20. At this time, when the underwater heater 19 is energized at the same time, the water that is squeezed to a very small amount by the flow rate regulator 20 and passes through the water maintained at a constant temperature by the temperature regulator 18 passes. All the passing water temporarily accumulates in the activated carbon 22 in the water purification container 21. The water accumulated in the water purification container 21 is dropped on the coffee 25 in the filtration chamber 24 through the activated carbon 22 because the bottom of the water purification container 21 is the mesh net 23, and is extracted because the coffee is extracted. The coffee liquid accumulates in the coffee container 26. What should be noted here is the temperature of the water passing through the water purification container 21. When high-temperature water passes through the activated carbon 22, in addition to physical adsorption, it enhances the water purification effect of the activated carbon 12 by decomposing free chlorine that causes the unpleasant odor and off-flavor, in addition to physical adsorption. Since there is no activated carbon, the life of activated carbon can be increased.

FIG. 3 and FIG. 4 show a brewing coffee extractor showing still another embodiment. Reference numeral 27 denotes a water container for storing water, and a flow controller 30 is provided at an outlet at a lower portion of the water container 27. Reference numeral 31 denotes a hot plate. Activated carbon 32 is charged into the hot plate 31, and a net 33 having a fine mesh is used at the outlet. A heater 28 heats the hot plate 31, and the power is turned on and off by a temperature controller 29 which can keep the heated hot plate 31 at a constant temperature. Below the hot plate 31, there is a coffee container for storing the coffee liquid extracted in the filtration chamber 34 for extracting the coffee 35.

Next, the operation of the above configuration will be described. Water container 27
And the water in the water container 27 is passed by a small amount by the flow rate regulator 30. At the same time, the power of the heater 28 is turned on to heat the hot plate 31 to keep it at a constant temperature. The flow regulator
All the water that is squeezed to a small amount at 30 and passes through is temporarily retained in the activated carbon 12 in the hot plate 31. Water accumulated in the hot plate 31 passes through the activated carbon 32 because the bottom of the hot plate 31 is a mesh net 33, and is filtered.
Since the coffee is extracted by dropping it on the coffee 35 in 34, the extracted coffee liquid accumulates in the coffee container 36.
What should be noted here is the hot plate 31 containing the activated carbon 32
Is purified while heating the water passing through the flow control device 30 which is squeezed to a very small amount.
Only the heated water is heated. After the passing water is completed, the activated carbon 32 is dried and the activated carbon 32 is further heated.

Because it is always dry at the start of use of activated carbon 32,
By heating the activated carbon 32 in a sanitary manner, a reactivating effect can be obtained, and the activated carbon can be used semipermanently.

In addition, in Examples 2 and 3, the effect is continued with a small amount of activated carbon and there is no need to replace it semipermanently.

EFFECT OF THE INVENTION As is clear from the description of the above-mentioned embodiment, the brewed coffee extractor of the present invention can obtain more delicious brewed coffee by purifying water using adsorption of activated carbon.

In addition, water is purified using activated carbon adsorption and catalytic reaction, and after passing the water, the wet activated carbon is dried and heated by a heating device. By continuing the effect, a delicious coffee can be obtained semipermanently. That you can do it.
