Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drip coffee extractor equipped with a water tank.

[0002]

2. Description of the Related Art It has been generally known that in the extraction of coffee, it is generally preferred that a person naturally pour hot water into an extractor in which coffee powder is set as a method for extracting delicious coffee. Therefore, even with this type of electric coffee brewing apparatus, in order to approach coffee brewing by naturally pouring hot water with human hands, it has been conventionally known, for example, in Japanese Patent Laid-Open No. 1-1782.
A structure as shown in Japanese Patent No. 11 has been proposed. This will be described with reference to FIG.

FIG. 23 shows a conventional coffee brewing apparatus of this type. Water in a water tank 1 is sent to a heater 4 of a main body 3 via a check valve 2 to be heated and boosted to flow in a hot water supply passage 5. It is going to rise.

Reference numeral 6 designates a substantially disc-shaped rotary plate. The rotary plate 6 has eight curved blades 7a and 7b radially erected at a position point-symmetrical with respect to the center thereof, and the whole circumference thereof. A wall 8 which is 1 to 2 mm higher than the height of the blade 7 is provided, and a through hole 10 in which a step portion 9 having a partially reduced diameter is formed is provided in the central portion, and the central portion and the blade 7 are provided.
A pouring port 11 is provided at a substantially middle position. Reference numeral 12 is a shaft rod in which an engaging portion 13 is formed by enlarging the diameter of the lower end, and the shaft rod 12 holds the step portion 9 of the through hole 10 of the rotating plate 6 rotatably by the engaging portion 13. There is.

Reference numeral 14 is a bearing hole provided in the main body 3. The bearing hole 14 is penetrated by the upper portion of the shaft rod 12, and the shaft rod 12 is an E-shaped ring 15 which serves as the bearing hole 1.
4 is rotatably held.

Therefore, the hot water that has risen in the hot water supply passage 5 is discharged from the discharge port 1.
It is discharged from the blade 6 and hits the blade 7a of the rotary plate 6 at a right angle and pushes it. Further, due to this rotation, a new blade 7b is positioned in front of the discharge port 16. The blade 7b is further pushed by the hot water discharged from the discharge port 16. On the other hand, the hot water discharged from the discharge port 16 stays on the rotating plate 6 after being pressed by the blade 7b on the rotating plate 6 because it is surrounded by the wall 8 provided on the entire circumference. Since the rotary plate 6 is eccentrically provided with one pouring port 11, the hot water on the rotary plate 6 falls into the extractor 17 along with the rotation of the pouring port 11 as the rotary plate 6 rotates. Also,
Since the flow of hot water is continuous, the hot water falling from the pouring port 11 drops into the extractor 17 while rotating, and coffee is continuously extracted.

Further, as a so-called coffee machine with a mill, there is, for example, a structure shown in FIG.
As shown in FIG. 24, a crushing chamber 18 for crushing coffee beans is provided in the main body, and a cutter 20 connected to a motor 19 is provided.
The coffee beans are crushed by constantly rotating at a constant speed and dropped into the extractor 17 through the holes of the mesh filter 21. Therefore, the coffee beans are ground uniformly, and there is no astringency, and as a result, it contributes to the extraction of delicious coffee.

[0008]

By the way, the characteristic of the above-mentioned method of extracting coffee by hand is that the hot water is continuously and uniformly poured over the coffee powder. This makes it possible to extract delicious coffee.

However, in the above-mentioned conventional structure, even if the coffee powder can be continuously poured from the pouring port 11 into the coffee powder, the rotation of the rotary plate 6 provided above the pouring device 17 causes the momentum of the hot water to be discharged. Determined by Therefore, the hot water dropped from the pouring port 11 is also determined by this, and the trajectory of pouring the coffee powder is limited depending on the momentum of the hot water. Then, it was not always possible to pour the coffee powder on the whole evenly, and as a result of pouring with a bias, the coffee concentration was not constant and delicious coffee could never be extracted. .

In a coffee extractor equipped with a mill, it is important to grind coffee beans uniformly in order to extract delicious coffee. In this regard, conventionally, this has been achieved by rotating the cutter 20 for crushing coffee beans at a constant speed. But,
This is suitable when one coffee grain does not move with respect to the rotation of the cutter 20, but in reality, every one rotation of the cutter 20 causes one coffee bean to move. As the position changes, the amount of change (movement) is irregular. Therefore, for this, the cutter 20
If the rotation of the coffee beans was kept constant, it could not be said that coffee beans were crushed evenly, and it took time to crush them evenly.

Further, after the coffee beans are ground, the grinding chamber 1
Since the oil content of the coffee beans clings to the inside of item 8, it was difficult to care for after use, and the life of the device itself was shortened depending on the condition of care.

The present invention solves the above-mentioned conventional problems, and a first object thereof is to extract hot water from hot water to coffee powder continuously and uniformly. An object of the present invention is to provide a coffee extraction device that can always extract delicious coffee of constant quality by pouring hot water.

The extraction process period for extracting coffee is detected, and hot water is uniformly poured during this extraction process.
The second purpose is to ensure that the molten metal can be poured evenly.

A third object of the present invention is to provide a coffee brewing device which can be poured evenly by controlling the heating output and which can be easily realized.

A fourth object of the present invention is to provide a coffee extractor capable of pouring water uniformly by controlling the heating output so that the structure is simple, the assemblability is good, and the number of failures is small.

A fifth object of the present invention is to provide a coffee extractor capable of uniformly grinding coffee beans in a short time.

A sixth object of the present invention is to provide a coffee extracting device which can grind coffee beans without waste.

Further, a seventh object of the present invention is to provide a coffee brewing device with a long-life mill which can efficiently clean the crushing chamber after use.

[0019]

A hot water outlet that is guided from the hot water outlet to the hot water outlet, an extractor having a filter that receives hot water from the hot water outlet, a container that receives the coffee liquid extracted by the hot water outlet, and hot water from the hot water outlet. And a heating output control means for controlling the heating output of the heating means based on a pouring part having a diffusing member for diffusing the hot water on the extractor and a chaos signal generating means for generating a chaos signal. It has a configuration with.

A fifth problem solving means of the present invention which achieves the above fifth object is a water storage tank, a heating device for heating water supplied from the water storage tank and sending it to a hot water supply passage, An outlet having a hot water discharged from the hot water outlet to the hot water outlet, an extractor having a filter for receiving hot water from the hot water outlet, a container for receiving the coffee liquid extracted by the hot water outlet, and feeding coffee beans to the extractor. Along with this, a crushing chamber provided with a cutter for crushing the coffee beans, a driving means for rotating the cutter, a chaos signal generating means for generating a chaos signal, and a rotation of the driving means based on the chaos signal generating means. And a rotation control means for controlling.

A sixth problem solving means of the present invention for achieving the sixth object is a mill step detecting means for detecting the start and end of crushing of coffee beans in the configuration shown in the fifth problem solving means.

When the extraction step is detected by the extraction step detection means, the rotation of the cutter is controlled based on the chaos signal generation means.

[0026]

With the first means for solving the problem, the hot water supplied from the hot water outlet is poured from the hot water outlet into the pouring portion. The rotation of the pouring section is chaotically changed by the chaos signal generating means, so that the centrifugal force of the pouring section changes. Then,
Along with this, the pouring of the hot water also changes chaotically, and without drawing a constant pouring trajectory, as a result, the hot water can be poured evenly throughout the extractor set with the coffee powder.

When the extraction step detecting means detects the extraction step by the second problem solving means, the rotation of the pouring portion is changed by the chaos signal. Therefore, the pouring part can be reliably operated during the extraction process period in which the pouring part needs to be changed chaotically.

In the first problem solving means, the pouring portion is forcibly rotated by the driving means, but in the third problem solving means, the pouring portion is rotatably arranged and the pouring port Since it rotates by receiving the force of the discharged hot water, the amount of hot water discharged from the hot water outlet is changed chaotically, and the rotation of the pouring part is changed chaotically. That is, since the amount of hot water to be discharged can be changed by controlling the heating output of the heating means, the heating output of the heating means is chaotically changed.

Further, in the fourth means for solving the problems, since the hot water from the hot water outlet is changed and a diffusing member for diffusing the hot water is provided on the extractor, the amount of hot water discharged from the hot water outlet is chaotically changed. Then, the direction of scattering when hitting the diffusing member is changed chaotically. That is, since the amount of hot water to be discharged can be changed by controlling the heating output of the heating means, the heating output of the heating means is chaotically changed.

Further, in the fifth means for solving the problems, when the cutter for crushing the coffee beans in the milling process starts to rotate, one grain of coffee beans moves irregularly with each revolution, but Since the rotation changes chaotically by the chaotic signal generating means, the rotation of the cutter never takes the same number of rotations. Therefore, the cutter and the coffee beans do not hit each other again, and as a result, the coffee beans can be ground uniformly as a whole.

According to the sixth problem solving means, when the milling process detecting means detects the milling process, the rotation of the cutter is changed by the chaos signal. Therefore, the cutter can be reliably operated during the milling process in which the cutter needs to be chaotically changed.

In the seventh means for solving the problem, when the coffee is extracted, the cutter is rotated again to pour hot water into the coffee bean inlet to wash the powder remaining in the crushing chamber. Since the rotation of the machine is chaotically changed by the chaotic signal generating means, the cutter and the hot water do not hit the same way again like the above, and as a result, the hot water is evenly distributed in the grinding chamber as a whole, and It can be washed efficiently in time.

[0033]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

(First Embodiment) The first embodiment of the present invention will be described below.

In FIG. 1, the water in the water storage tank 30 made of transparent heat-resistant synthetic resin is passed through the check valve 31 to the main body 3
It flows into the second heating pipe 33 and is heated by the heater 34 which is a heating device. When the water is heated and expanded, the check valve 31 is closed by pressure and is pushed up to the cock packing 36 which is the switching means through the hot water supply passage 35. At this time, the cock packing 36 is in the position shown in B of FIG. 1, and the hot water returns to the water tank 30. Then, when the hot water in the heating pipe 33 is exhausted, the pressure decreases, the check valve 31 opens, and water flows in. By repeating the above operation, the water tank 30
The water inside circulates and the water temperature rises (circulation process). And
When the water temperature rises to about 70 ° C., the position of the cock packing 36 moves to the position shown in A of FIG.

A pouring portion 39 is rotatably provided at the tip of the tap opening 38 of the tap passage 37. The pouring part 39 is shown in FIG.
Shown in. In addition, it is almost the same as the conventional configuration in FIG.
The same components are given the same numbers and their explanations are omitted. In FIG. 2, a chaotic signal generating means 40, a rotation control means 41, and a motor 42 as a driving means are provided to rotate the pouring part 39. The pouring unit 39 is rotatable by a rotation control unit 41 based on a chaos signal generating unit 40 that generates a chaos signal. Further, when the hot water temperature is 70 ° C. or higher, the flow path is changed to the hot water discharge path 37 by the cock packing 36, but the extraction process detecting means 43 shown in FIG. 7 starts the extraction process when the flow path is switched to the hot water flow path 37. Is output. And the chaos signal generating means 40
Outputs a chaos signal to the rotation control means 41 and causes the motor 42, which is a driving means, to rotate the pouring portion 39.

Here, an example of the chaos signal generating means 40 will be described. The following function is an example of a function that creates a chaos signal.

F (X) = 2 × X (0 ≦ X <0.5) F (X) = 2 × (1-X) (0.5 ≦ X ≦ 1) The graph of FIG. Becomes A method of generating a chaotic signal will be described with reference to the graph of FIG. That is, when the initial value A is calculated as the X value of F (X),
F (X) = X1. This X1 is calculated again as the X value of F (X), and the result of F (X) = X3 is obtained. Repeating the above calculation N times, X1, X2, X3, ... X
(N) can be obtained. That is, it is known that X (n) obtained by repeating the above calculation changes chaotically, and the data X (n) can be used as a chaotic signal.

A specific structure will be described with reference to FIG. Figure 4
In 101, an initial value input means 101 outputs the initial value A as an X value to the function operation means 102. Function calculation means 1
03 is X = A, the calculation result of the function calculation means 103 is stored in the storage means 104, and the stored value is input again as the X value of the function calculation means 103. Reference numeral 105 denotes an occurrence count comparison means, which is a function calculation means 103.
When the number of times of calculation in step reaches a predetermined value, the function calculating means 103
It stops the operation of.

The operation of the chaotic signal generating means 40 is shown in FIG.
Will be described. First, n = 0, the initial value X0 of the function F (X) is A, and the initial value of the number of times N is B (steps 1 to 1).
3). Next, F (X) is calculated, and the calculation result is stored as the X value of the next F (X), that is, Xn + 1 (step 4). Next, the value of n is incremented by 1 (step 5), and it is determined whether this n value has reached the initially set number N (step 6). If not reached, steps 4 to 6 are repeated, and if reached, the program ends.

The chaos signal of the chaos signal generating means 40 changes as shown in FIG. 6, and the pouring section 39 is rotated by using this chaos signal. Therefore, the hot water supplied to the pouring unit 39 is poured onto the coffee based on the chaotic centrifugal force of the pouring unit 39, and the extracted coffee passes through the extractor 45 in which the filter 44 is set and the container 46. It is extracted inside (extraction step).

The operation in this series of steps is shown in FIG.
Is shown in. In FIG. 8, a chaotic signal is generated and output by the start of the extraction process, and the pouring unit 39 is generated based on this.
Rotate to perform extraction and confirm that the extraction process continues. Then, when the extraction process is finished and the output of the chaos signal is finished at the same time, the rotation of the pouring unit 39 is finished and the extraction is completed.

Therefore, in the present embodiment, the hot water outlet 37
The hot water supplied from the pouring machine is poured into the pouring section 39 through the tap hole 38. The pouring unit 39 chaotically changes its rotation by the chaos signal generating means 40, so that the pouring unit 39
The centrifugal force of changes. Then, along with this, the pouring also changes chaotically and a constant pouring trajectory is not drawn, and as a result, the coffee powder can be poured evenly on the extractor 45 as a whole.

When the extraction process detecting means 43 detects the extraction process, the rotation of the pouring unit 39 is changed by the chaos signal. Therefore, the pouring unit 39 can be reliably operated during the extraction process period in which the pouring unit 39 needs to be changed chaotically.

In the present embodiment, the extraction process detecting means is provided, but the present invention is not limited to this, and the pouring part is automatically opened when the power is input without providing the extraction process detecting means. Even if it rotates based on the chaos signal generating means, the same effect can be obtained.

(Second Embodiment) A second embodiment of the present invention will be described below with reference to FIGS. 9 and 10. The same parts as those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the second embodiment of the present invention, instead of the pouring part in the first embodiment, a discharge passage for branching the tapping water is provided at the tip of the tapping port, which is shown in FIG.

In FIG. 9, reference numeral 47 denotes a discharge path (pouring section) that branches the hot water at the tip of the hot water outlet 48, whereby the hot water from the hot water outlet 48 is branched and poured.
Further, the discharge passage 47 is rotatable by the rotation control means 41 based on the chaos signal generating means 40 for generating a chaos signal.

Therefore, when the extraction process is started, the extraction process detection means 43 outputs the start of the extraction process. And
A chaos signal is sent to the rotation control means 41 by the chaos signal generating means 40, and the discharge passage 47 is rotated by the motor 42 which is a driving means. The chaotic signal generating means 40 is the same as that shown in the first embodiment.

Therefore, also in this embodiment, the same effect as that of the first embodiment is obtained, and the hot water discharged from the discharge passage 47 chaotically changes the rotation of the discharge passage 47 by the chaos signal generating means 40, so that the discharge is performed. The centrifugal force in path 47 changes. Then,
Along with this, the pouring also changes chaotically and does not draw a constant pouring locus, so that the coffee powder can be poured evenly on the extractor 45 as a whole.

When the extraction process detecting means 43 detects the extraction process, the rotation of the discharge passage 47 is changed by the chaos signal. Therefore, the discharge passage 47 can be reliably operated during the extraction process period in which the discharge passage 47 needs to be changed chaotically.

In the present embodiment, the discharge passage 47 is provided at the center of the extractor 45 and the left and right flow passages have the same length, but the present invention is not limited to this and, for example, the drawing 10
Even if the center of the discharge passage 47 is displaced from the center of the extractor and the lengths of the left and right flow passages are changed correspondingly, the same effect can be obtained.

In this embodiment, the extraction process detecting means is provided. However, the present invention is not limited to this, and the discharging path is automatically chaotic when the power is input without providing the extraction process detecting means. Even if it rotates based on the signal generating means, the same effect can be obtained.

(Embodiment 3) A third embodiment of the present invention will be described below with reference to FIGS. The same parts as those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In the third embodiment of the present invention, the difference from the conventional configuration in FIG. 23 is that the heating output of the heater 19 as a heating device is changed by a chaos signal. The pouring unit 39 has the same structure as the conventional one as shown in FIG.

As shown in FIG. 11, a heating output control means 40a for controlling the heating output of the heater 34 and a chaos signal generating means 40 for supplying a chaos signal to the heating output control means 40a are provided.

In FIG. 13, a heater 34 as a heating device is connected to an AC power source 49 via a switching element 53. Reference numeral 50 is a zero voltage detecting means, which generates a signal synchronized with the zero voltage of the AC power supply. The heating output determination means 51 determines the heating output based on the outputs of the chaotic signal generation means 40 and the zero voltage detection means 50, and controls the switching element 53 of the heater 49 via the phase control means 52. The zero voltage detecting means 50 and the heating output determining means 5
1, the phase control means 52, and the switching element 53 constitute the heating output control means 40a.

FIG. 14 shows the output state of the heater 49, in which the heating output is chaotically turned on and off by the output from the chaos signal generating means 40.
That is, the heating output determination means 51 determines the delay time from the zero voltage time of the AC power supply to the turning on of the switching element, that is, the OFF time of the heating output based on the chaotic signal, whereby the heater 34 changes chaotically. It will be heated.

Therefore, conventionally, the amount of hot water discharged to the hot water outlet 37 after reaching a constant temperature is constant, but by changing the heating state of the heater 34 chaotically,
The amount of hot water that is heated and discharged also changes based on this. And since the pouring part 39 rotates by receiving the force of the amount of hot water discharged from the tap 38, the pouring part 39 also rotates chaotically, and as a result, the coffee powder is set without drawing a constant pouring locus. It is possible to uniformly pour the extractor 45 described above.

(Embodiment 4) A fourth embodiment of the present invention is shown in FIG.
5 will be described. The present embodiment has almost the same structure as the third embodiment, except for the structure of the pouring part. The structure of the pouring section will be mainly described below. In FIG. 15, the pouring part 39
Has a dome-shaped diffusing member 60, and the diffusing member 60
The discharge port 16 is disposed below the center of the dome and in the center of the dome. Therefore, the hot water discharged from the discharge port 16 hits the vicinity of the center of the inner surface of the dome-shaped diffusion member 60, changes its direction in all directions, and falls into the extractor 44 that receives the hot water from the diffusion member 60. According to this configuration, the discharge port 16
By changing the amount of hot water from the chaotically, the diffusion member 6
The amount of hot water corresponding to 0 changes, and the diffusing member 60 can change the direction and amount of splashing in all directions. Therefore, it is possible to uniformly pour the coffee beans into the extractor 45. Further, as shown in FIG. 16, a dome-shaped diffusing member 61 is provided below the discharge port 16 to diffuse hot water dropped from the discharge port 16 in all directions as shown by arrows in the figure. Can be obtained. In short, the diffusing member may have any shape as long as it diffuses the hot water from the discharge port in all directions.

(Fifth Embodiment) A fifth embodiment of the present invention will be described below with reference to FIG. The same parts as those in the above-described embodiments are designated by the same reference numerals and the description thereof will be omitted.

FIG. 17 shows a coffee extractor equipped with a mill. 54 is a crushing chamber for crushing coffee beans, in which a cutter 55 is rotatably disposed, and the cutter 55 is rotated to crush the coffee. The coffee beans in the chamber 54 are ground. Further, the cutter 55 is a motor 42 which is a driving means.
The motor 58 is driven and controlled by the cutter rotation control means 56 that changes the rotation speed based on the chaos signal generation means 40 that generates a chaos signal.

Therefore, as shown in FIG. 18, when the coffee beans are set in the crushing chamber 54 and the power is input, the mill process detecting means 57 outputs the start of the mill process. Then, the chaos signal generation means 40 sends a chaos signal to the cutter rotation control means 56, the motor 58 rotates the cutter 55 to crush the coffee beans, and the coffee beans are sent to the extractor 45 in which the filter 44 is set.

Further, as shown in FIG. 19, when the milling process is completed, heating is performed by the heater 34, and the process goes to a circulating process in which the heated water is returned to the water storage tank 30 again.
In the circulation process, when the temperature of the circulating water exceeds 70 ° C, the process moves to the extraction process. That is, the extraction process detection means 43 detects that the temperature has reached 70 ° C., outputs a start signal for the extraction process, and sends a chaos signal to the cutter rotation control means 56 by the chaos signal generation means 40 to cause the motor 42. Thus, the cutter 55 is rotated again for cleaning. The chaotic signal generating means 40 is the same as that shown in the first embodiment.

The operation of this series of steps is shown in FIG. In FIG. 19, a chaos signal is generated and output by the start of the milling process, and based on this, the cutter 55 is rotated by the motor 42 to grind the coffee beans and it is confirmed that the milling process is continued. Then, at the same time as the milling process is finished, the output of the chaos signal is also finished,
The rotation of the cutter 55 is completed, and the circulation process is started.

When the extraction step is performed through the circulation step, a chaos signal is generated and output by the start of the extraction step. Based on this, the pouring section 39 is rotated to perform extraction, and this hot water is used. Similarly, the inside of the crushing chamber 54 is cleaned by rotating the cutter 55 with the motor 42 based on the chaos signal. Then, by ending the output of the chaotic signal at the same time as the end of the extraction process,
The rotation of the pouring unit 39 and the cutter 55 is completed, and the extraction is completed.

Further, the basic characteristic of the chaotic signal has a mapping such as the Paocone transformation, and has the trajectory instability that it does not pass through the same state twice. "Paikone" is a process in which the dough is thinly stretched, folded in half and stretched again. Moreover, the movement amounts are not symmetrical with each other, and the movement amounts are not regular. And
As a result, the atoms of each other may be located at the ends of the pie.
However, when you look at the pie as a whole, this kind of situation occurs here and there, and as a whole, the state is that the state is well kneaded = well kneaded = delicious.

The present invention incorporates the basic characteristic of the chaotic signal in the grinding of coffee beans, so that each one rotation of the cutter 55 causes each coffee bean to move irregularly. Since the rotation of the cutter 55 is chaotically rotated, the movement of the coffee beans can be the same as the movement of the above-mentioned "Pai-Kone". That is, since the rotation of the cutter 55 is chaotically changed by the chaos signal generating means 40, the rotation of the cutter 55 is not the same as the number of rotations twice. Therefore, the cutter 55
The rotation and the contact with the coffee beans are never the same again, and as a result, the coffee beans can be ground as a whole as a whole.

Also, in the extraction step, the cutter 55 is rotated chaotically based on the chaotic signal, so that the cutter 55 and the hot water do not hit each other again. As a result, the hot water at the time of extraction is used. And then the crushing room 47
The inside can be uniformly cleaned in a short time.

In addition to the structure of the above embodiment, an extraction process detecting means 43 for detecting the extraction process shown in FIG. 21 is provided, and a rotation control means 41 for controlling the rotation of the pouring part 39 shown in FIG. 20 is provided. . According to the above-described configuration, as shown in FIG. 22, when the extraction step detecting means 43 detects the extraction step, the rotation of the pouring section 39 is changed by the chaotic signal, so that the pouring section 39 needs to be changed chaotically. The pouring unit 39 can be reliably operated during a certain extraction process period. Further, when the mill process detecting means 57 detects the mill process, the rotation of the cutter 55 is changed by the chaos signal, so that the cutter 55 can be reliably operated during the process period in which the cutter 55 needs to be changed chaotically.

In this embodiment, the milling process detecting means and the extracting process detecting means are provided, but the present invention is not limited to this, and either one or both of the milling process detecting means and the extracting process detecting means is provided. For example, even if the cutter is rotated at the same time when the power is input, the same effect can be obtained.

In each of the above-mentioned embodiments, a circulation heating type having a circulation process by the switching means is used, but coffee of a system in which hot water is poured into the extractor immediately after heating the heater without providing the circulation process. It can also be applied to extractors.

[0073]

As is apparent from the above, according to the present invention, a pouring unit capable of rotating corresponding to an extractor for extracting coffee is provided at a tap, and a chaos signal generating unit for generating a chaos signal is generated. By providing means, rotation control means for controlling the rotation of the pouring part while rotating the pouring part based on the chaos signal generating means, and drive means for rotationally driving the pouring part, The pouring water supplied to the pouring part changes chaotically due to the change in centrifugal force due to the chaotic rotation of the pouring part, and the pouring trajectory does not draw a constant pouring path. As a result, it is possible to pour the coffee powder into the pouring machine as a whole, and it is possible to always extract delicious coffee of a constant quality and a constant quality.

Further, since the extraction process detection means detects the coffee extraction process and the rotation control means rotates the pouring part, the pouring part can be reliably rotated without waste,
You can always pour the metal in a stable and even manner. Moreover,
Since the rotation of the pouring part is stopped after the extraction step, it is possible to prevent the pouring part and the like from being damaged by touching the rotating pouring part when the extractor is taken out after the extraction step.

Further, the heating output of the heating means is controlled based on a pouring portion which is rotatably arranged at the outlet and obtains a rotational force by the hot water from the outlet and a chaos signal generating means for generating a chaos signal. By providing the heating output control means for controlling, the amount of hot water discharged from the hot water outlet can be changed by controlling the heating output of the heating means. As described above, it is possible to constantly extract delicious coffee of a constant quality and a constant quality without providing a driving means in the pouring section. Moreover, it is not necessary to provide a drive unit such as a motor for rotating the pouring unit, and the assembly can be more easily performed, and the productivity can be improved.

Furthermore, instead of rotating the pouring part,
By simply providing the diffusion member for diffusing the hot water from the discharge port, the structure can be simplified and the productivity can be dramatically improved. Further, since no rotating structure is required, there are few failures, and it is possible to pour the molten metal evenly over a long period of time.

Further, in the coffee extracting device with a mill, a crushing chamber provided with a cutter for crushing coffee beans corresponding to the extractor is provided, and a chaos signal generating means for generating a chaos signal and the chaos signal generating means. By providing the rotation control means for controlling the rotation of the cutter based on the signal generating means and the drive means for rotationally driving the cutter, when the cutter for crushing the coffee beans starts to rotate in the milling process, one rotation is performed. Each one of the coffee beans moves irregularly every time, but the rotation of the cutter changes chaotically by the chaos signal generating means, and the rotation of the cutter does not reach the same number of rotations twice, so the cutter and coffee beans are As a result, the coffee beans will never be the same again, and as a result, the coffee beans can be crushed as a whole, making for delicious coffee extraction. It is those that can be Azukasuru.

Further, when the extraction process is detected by the extraction process detecting means, the rotation of the pouring part is changed by the chaotic signal, so that the pouring part can be reliably operated during the extraction process during which the pouring part needs to be changed chaotically. It can be operated.

Furthermore, when the mill process is detected by the mill process detecting means, the rotation of the cutter is changed by the chaos signal, so that the cutter can be reliably operated during the mill process period in which the cutter needs to be changed chaotically. In addition, it is possible to provide a coffee extraction device that is efficient in electricity bills, such as being able to surely extract delicious coffee, and to save electricity bills associated with it without rotating it for an unnecessary period. is there.

In the extraction step, the cutter is rotated again to pour hot water into the coffee bean inlet to wash the powder remaining in the crushing chamber. Since it changes chaotically by the means, the cutter and the hot water do not hit the same way again like the above, and as a result, the hot water is evenly distributed in the crushing chamber as a whole and can be efficiently washed in a short time. It is possible to provide a coffee brewing device having a long life.
