Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a coffee extracting machine with an attachable water suppling block,

TECHNICAL FIELD [0002] The art disclosed herein relates to a coffee extracting apparatus, and more particularly to a coffee extracting apparatus having a detachable block-shaped water supply unit.

Coffee is a beverage that harvests the fruit of a coffee tree, roasts it through the processing process, and then mixes the obtained coffee bean with water, or extracts the liquid coffee with water and drinks it.

As a method of extracting liquid coffee using water, there is a method of extracting liquid coffee by extracting liquid coffee by pouring water at room temperature into a filter paper containing coffee, filling the pot with coffee, passing hot water at high pressure, Extraction of espresso coffee, and the like.

Caffeine content, coffee taste, and coffee aroma vary depending on the extraction method of liquid coffee. It has been reported that the higher the water temperature used in the extraction process, the higher the caffeine content of the extracted liquid coffee. Since the liquid coffee extracted through the espresso coffee extraction method is extracted through the high temperature water at high pressure, the caffeine content is higher than that of the liquid coffee extracted by the drip coffee extraction method using the water at room temperature.

Recently, as the demand of consumers for quality fine coffee and the trend of drinking coffee by using a direct coffee machine at home have been increasing, the market for drip coffee having low caffeine content and deep and soft taste is increasing.

Drip coffee is also known as Dutch coffee, and has the advantage of dropping water into the solid coffee contained in the coffee tank and extracting the liquid coffee from the solid coffee, so that the caffeine content is small and can be stored for a long time. However, since drip coffee extracts liquid coffee with water at room temperature, the extraction time is long. In addition, the drip coffee drops a drop of water to extract the liquid coffee, so that the liquid coffee is excessively extracted in the solid coffee in which the water falls only in a part of the solid coffee and the water is in contact with the solid coffee. There is a problem that the liquid coffee is not extracted. In addition, when the amount of water contained in the water tank is reduced in the extraction process, the drip coffee has a problem in that the water pressure is reduced and the amount of water dropped decreases, so that it is difficult to accurately control the amount of water supplied to the coffee tank.

As another example, as shown in the figure, a projection 134-3d may be formed at a portion where the one end of the plurality of channels 134-3c is connected to the second inlet 134-3a, . The protrusion 134-3d may have a conical shape or a polygonal conical shape so that water flowing into the second inlet 134-3a may be distributed to the plurality of channels 134-3c uniformly.

In other words, the modified water distribution portion 134 shown as an example in FIG. 5 distributes the water introduced into the water distribution portion 134 to the through holes 134-3b through the plurality of channels 134-3c, The water can be effectively and efficiently distributed to the coffee extracting unit 140 irrespective of the amount of water flowing into the water distribution unit 134.

As described above, the coffee extracting apparatus 100 disclosed in this specification can uniformly extract coffee by spreading water through the water distributing unit 134 and supplying the water to the coffee extracting unit 140. In other words, in the conventional drip type coffee extracting apparatus, in the solid coffee 20 in which water comes into contact with only a part of the solid coffee 20 contained in the coffee extracting unit 140, the liquid coffee 30 is excessively There is a problem that the liquid coffee 30 is not extracted in the solid coffee 20 which is extracted and not in contact with water. In addition, when the liquid coffee 30 is extracted through the conventional drip extraction apparatus, the liquid coffee 30 is extracted only by the part of the solid coffee 20 in which the water falls, The content is increased and the coffee aroma is reduced. Alternatively, the coffee extracting apparatus 100 disclosed herein may uniformly dispense water from the solid coffee 20 by providing water dispensed through the water distributor 134 to the solid coffee 20 contained in the coffee extractor 140 Coffee can be extracted. Thus, the time for extracting the liquid coffee 30 from the solid coffee 20 can be shortened, and the taste and flavor of the liquid coffee 30 to be extracted can be stably controlled.

The coffee extracting unit 140 is supported by a cradle 110 and receives the solid coffee 20 therein and extracts the liquid coffee 30 by using the water dispersed and distributed by the water supply unit 130 .

The coffee receiving portion 150 receives the liquid coffee 30 extracted by the coffee extracting portion 140.

The controller 160 may control the operation of the first flow rate controller 136 and the second flow rate controller 138.

For example, the extraction time for extracting the liquid coffee 30 can be created and stored based on the amount of water used for extraction and the water supply speed. The extraction time for extracting the liquid coffee 30 may be prepared and stored according to the type, the type, and the like of the solid coffee 20. In this case, the recipe may be subdivided and stored in the database based on at least one of a type of solid coffee 20 accommodated in the coffee extracting unit 140, a processing state, and a combination thereof.

The control unit 160 may control the operation of the first flow rate controller 136 and the second flow rate controller 138 to extract the liquid coffee 30 according to a user's input command or a preprogrammed system. For example, the user can select a desired recipe through the input unit, and the controller 160 controls the first flow rate controller 136 and the second flow rate controller 138 according to a recipe selected by the user through the input unit, The liquid coffee 30 can be extracted by repeatedly or repeatedly controlling the operation of the liquid coffee 30 in sequence.

As another example, the user can input the amount of the liquid coffee 30 and the extraction time of the liquid coffee 30 extracted from the desired solid coffee 20 through the input unit. In this case, the control unit 160 controls the first flow rate regulator 136 and the second flow rate regulator 138, which sequentially proceed from the first reference level and the second reference level of the preset water storage unit 132, The amount of water to be supplied to the coffee extracting unit 140 from the spinning operation (hereinafter referred to as the amount of water injected once) can be calculated. The user can determine the number of operations of the first flow rate controller 136 and the second flow rate controller 138 for extracting the amount of the liquid coffee 30 desired by the user.

Accordingly, the coffee extracting apparatus 100 disclosed in this specification can provide the user with a desired amount of the liquid coffee 30 at the extraction time inputted by the user through the input unit.

The water level sensor 170 is disposed in the water storage part 132 and can sense the water level of the water storage part 132. As the level sensor 170, an optical sensor, a floating sensor, or the like may be used. In the figure, an optical sensor attached to the outer wall of the water storage part 132 as the water level sensor 170 is shown as an example. In this case, the water storage part 132 may be made of a light-transmitting material. The light sensor may include a light emitting unit (not shown) and a light receiving unit (not shown). The light emitting unit 132 emits light, and the reflected light is measured through the light receiving unit, ) Can be detected.

The water level of the water storage part 132 sensed by the water level sensor 170 may be provided to the controller 160. [

As another example, a floating sensor (not shown) may be used as the level sensor 170, unlike the one shown in the drawings. The floating sensor is disposed inside the water storage part 132 and can operate on the same principle as a normal floating gate. The floating sensor rises as the water level of the water storage part 132 rises and falls as the water level rises. Accordingly, the floating sensor can sense the water level of the water storage part 132. The water level of the water storage part 132 sensed by the water level sensor 170 may be provided to the controller 160. [

The control unit 160 may control the water level of the water storage unit 132 based on the water level information of the water storage unit 132 received from the water level sensor 170. More specifically, the control unit 160 may open the first flow rate control unit 136 to supply the water contained in the water tank 120 to the water storage unit 132. When the water level of the water storage part 132 detected by the water level sensor 170 reaches the first reference level, the first flow rate regulator 136 is closed and the second flow rate regulator 138 is opened, The water contained in the water distribution portion 132 can be supplied to the water distribution portion 134. When the water level of the water storage part 132 detected by the water level sensor 170 reaches the second reference level, the second flow rate regulator 138 is closed and the first flow rate regulator 136 is opened, 120 may be supplied to the water reservoir 132 so that the amount of water supplied through the first outlet 132a can be adjusted. This process can be repeated for a period of time to extract a desired amount of the liquid coffee 30 through the coffee extracting unit 140. The controller 160 can control the amount of water supplied to the water distributor 134 intermittently or periodically. The first reference water level may be determined in consideration of the water level at which the water stored in the water storage part 132 comes into contact with the upper part of the water storage part 132 considering the shape of the upper part of the water storage part 132 . The second reference water level may be determined on the basis of the water level at which the water contained in the water storage part 132 is not discharged through the first outlet 132a but stays therein.

For this purpose, a water level indicator indicating the water level may be disposed on the inner surface or the outer surface of the water storage part 132. In this case, the user can open the first flow rate regulator 136 while the second flow rate regulator 138 is closed to fill the water reservoir 132 with the desired water level. The first flow rate regulator 136 is closed and the second flow rate regulator 138 is opened to allow the water contained in the water reservoir 132 to be supplied downward through the first outlet 132a. Accordingly, the coffee extracting apparatus 100 disclosed in this specification can control the amount of water supplied to the coffee extracting unit 140 by manual operation.
