Description

Distributor-having automatic coffee maker with distributor

The present invention relates to a fully automatic coffee maker for selectively extracting coffee by using roasted coffee beans and green beans. More specifically, the structure of the distribution unit is improved to increase the distribution efficiency and do not use a separate cooling device. The present invention relates to a fully automatic coffee maker having a distributor which improves the cooling efficiency by the natural cooling method and distributes the cooled coffee beans to the pulverization unit without a separate conveying unit, and then pulverizes them by vertical screws. .

Conventional automatic coffee makers use roasted coffee beans to grind to extract the coffee liquid, so it is necessary to purchase roasted coffee beans in advance. Therefore, in order to solve this problem, coffee makers have been developed and used to heat and distribute green coffee beans by heating means to automatically grind and extract them. However, the structure of the roasting process is complicated and the structure is also complicated, especially the already roasted coffee beans there was a discontinuity can not be used at the same time. In some cases, it is possible to put some roasted beans, but this is accompanied by inconvenience of using the roasted beans because the inlets of the green beans and the roasted beans are separated.

In addition, coffee makers using green beans have agitation blades vertically rotated inside the distribution kiln, in which the distribution unit is horizontal, in addition to the aforementioned problems, so that the green beans are roasted by stirring with agitating blades, so the green beans are not fully stirred. The green beans at the bottom have a problem of not being distributed evenly and burned or pressed.The coffee beans are placed between the discharge shutters because the horizontal open shutter is installed to transfer the roasted coffee beans to the grinder. There is a problem that the grinder is not operated well due to the problem that the heat distribution is lost due to the pinching problem and the green beans that are not roasted immediately fall or are transferred to the grinder.

And since the shell of the green beans peeled during the roasting operation is separated through the slots installed on the inner wall of the roasting kiln horizontally installed, the shell is not efficiently separated and there is a closed end where the shell is mixed in the coffee that is crushed and extracted. Conventional power distribution unit is equipped with a separate cooling fan for cooling after power distribution, so excessive noise is generated and the inside of the machine becomes dirty due to the scattering of the bean shell by the rotation of the cooling fan and flows into the coffee powder. There was a problem of deteriorating the taste.

In addition, in the crushing unit, a grinder using a pulverization cutter, which is generally called a mill, or pulverization is performed using the same principle as millstone, so the pulverization speed is slow and coffee beans are caught in the cutter, thereby preventing smooth pulverization. The grinding efficiency was low and the cleaning was not easy.

An object of the present invention is to solve many problems of the prior art, by rotating the stirrer itself without installing a separate stirring blade inside the distributor to ensure that the stirring of the coffee beans as a whole as well as the shell generated during the stirring This centrifugal force is to smoothly discharge through the hole drilled in the outer wall of the stirrer to increase the power distribution efficiency.

Another object of the present invention by eliminating the installation of a separate cooling blower for cooling the roasted coffee beans by applying a natural cooling method that is cooled by idling the distributor after the distribution is finished by eliminating noise and vibration and cooling time It is to reduce the cooling and increase the cooling efficiency.

Yet another object of the present invention is to drop the coffee beans that have been completely roasted by a natural dropping method without dropping them into a separate transport device, thereby simplifying the structure and miniaturizing and reducing the weight of the synthetic resin screw vertically. It is to provide a fully automatic coffee maker by rotating to increase the grinding efficiency.

In order to achieve the above object, the present invention provides a drip-type maker, which has one side open and a distributor having a shell discharge hole formed on the outside thereof so as to rotate itself by a motor, and an opening / closing door is opened on one side of the opening in communication with the green bean inlet. A distribution unit which opens and closes; A cylinder having coffee beans that are roasted and dropped below the opening and closing door of the distributor, a screw having a conical lower portion vertically installed and rotated therein, and detachably attached to the lower portion of the cylinder to correspond to the conical lower portion of the screw. It is characterized by consisting of a crushing portion having an inclined surface and a grinding blade piece having an extraction hole formed in the center thereof.

On the other side of which the one side is opened inside the outer cylinder 17, the distributor 13 which is connected to the rotary shaft 18 of the motor M and rotates in the correct position is provided. The electric distributor 13 is provided with a heating means such as a heater 15 therein, and a plurality of stirring blades 19 are protruded on the inner surface, and a shell discharge hole 20 through which the shell is discharged is penetrated on the outer surface. And one side of the opening part is connected to the green bean inlet 12 and the other part is the solenoid 21, the opening and closing door 23 to be opened and closed around the upper hinge 22 is installed and the outer cylinder surrounding the distributor 13 ( At the bottom of 17), a guide duct 24 connected to the shell recovery opening 9 of the outer case 1 is provided.

The lower part of the power distribution unit 100 is provided with a crushing unit 200 for pulverizing coffee beans falling after the power distribution is completed. The crushing unit 200 is a cylindrical body 25 for receiving coffee beans that are roasted and dropped below the opening and closing door 23 of the power distribution unit 13, as shown in the enlarged view of FIG. An inclined surface 26 and a grinding blade piece 27 which are attached to the lower portion of the electric cylinder 25 to be detachably attached and corresponding to the conical lower portion of the screw 14. ), And an extractor 29 having a central discharge hole 28.

In addition, the lower part of the crushing unit 200 has dripters 2 for drip mixing and mixing coffee powder and hot water that are crushed and dropped from the discharge hole 28 in the center, and are placed on the support jaw 5. A filter 30 is set on an inner surface of the rotor 2, and a port 3 receiving coffee liquid drips into the drip hole 31 of the dripter 2 is attached to the upper part of the mounting table 6 at the lower part thereof. It is.

In the present invention, the green beans are introduced through the green bean inlet 12 and roasted as the heating of the heater 15 in the distribution unit 100, and the roasted coffee beans are pulverized in the pulverization unit 200 as fine powder and have a dripter 2. At the same time dropping to the same time while supplying and mixing hot water to filter the residue as a filter (30) and then drip only the pure coffee liquid to the pot (3) heated as a heater 15 to obtain a coffee liquid of the present invention Since the distributor 13 has the rotary shaft 18 of the motor M installed on the other side of which one side is opened, the distributor 13 rotates itself by the rotation thereof, and the opening and closing door 23 is opened and closed as the solenoid 21. When green beans are introduced into the distributor 13 through the inlet to rotate the rotating shaft 18, the green beans are roasted by the heater 15 which is heated while being effectively stirred by the rotation of the distributor 13 itself. Being my Stirring is made more smoothly by agitating blades 19 protruding at regular intervals on the surface and the entire stirring is performed without stagnant green beans. The rotation of the distributor 13 is made to rotate for a predetermined time by a timer. In this process, when the operation of the heater 15 is stopped based on the time when the distribution is completed, the distributor 13 is the heater 15. Because the rotation of the operation is stopped for a set time in the stopped state of the natural cooling is made without the use of a blower can be effectively cooled in a fast time without the noise and vibration caused by the installation of the blower as in the prior art. Subsequently, when the timer reaches the set time, the distribution of the distributor 13 is automatically stopped and at the same time the solenoid 21 is operated to open and close the door 23 around the upper hinge 22. The beans flow down due to the inclination of the distributor 13 and naturally fall into a grinder installed directly below it.

And the soybean shell generated in the roasting process is separated into the inner wall surface by the centrifugal force due to the rotation of the distributor 13 is discharged to the shell discharge hole (20) drilled through it to the shell recovery port (9) through the guide duct (24) Unlike the conventional separation method, the shell is separated from the lighter shell than the bean by using centrifugal force, so the separation is ensured. In particular, the bean or the shell is smoothly discharged to the bottom without being caught in the opening / closing door 23. Naturally falling into the crushing unit 200 of the process, the exhaust gas generated during the roasting process is in communication with the power distribution unit 100 is automatically exhausted to the exhaust port 11 exposed to the upper surface of the outer case (1).

On the other hand, the roasted coffee beans fall to the pulverization unit 200 of the pulverization unit 200 to be crushed by falling to the pulverization unit 200 installed directly below it, without a separate transfer device. The screw 14, which is vertically installed and rotated when fed, transfers the coffee beans to the bottom, and the coffee beans transferred to the bottom are inclined surfaces of the extractors 29 installed to be in contact with the cylinder 25 in the lower portion of the conical screw 14. The grinding | pulverization is made between the grinding blade pieces 27 attached to (26), and it is discharged | emitted to the central discharge hole 28.

Thus, the roasted coffee beans fall down by the synthetic resin screw 14 which is dropped immediately without passing through the conveying apparatus and is vertically rotated, thereby making grinding and miniaturization and lightening of the coffee maker by omitting the conveying apparatus. Not only does the grinding efficiency increase, but the screw 14 is formed of a synthetic resin, which is harmless to the human body. In particular, since the extractor 29 is detachably installed, the extractor 29 is separated and, if necessary, the screw 14 is removed. And the inside of the cylinder 25 can be easily cleaned as a whole crushing unit 200.

The coffee powder pulverized by the crushing unit 200 and dropped through the central discharge hole 28 is introduced into the dripter 2 installed below the crushing unit 200, and at the same time, the pot 3 in the water tank 10 Hot water is supplied to the water supply hole 32 of the extractor 29 through the hot water supply pipe 16 contacted with the heater 15 installed at the lower part of the trough, and the coffee liquid drips and filters. Pure coffee liquor filtered by the residue 30 is stored in the lower port 3 through the drip hole 31 and heated by the heater 15.

The above described the process of roasting and crushing the green beans and extracting the coffee liquid, but the present invention uses the roaster 13 of the green beans distribution unit 100 without using a separate distribution unit 100 inlet as the roasted coffee beans. The coffee can be extracted by grinding and pouring in the same process as described above, and the coffee can be extracted. The present invention provides a timer and a reservation function to automatically extract coffee at a specified time.

As described above, the present invention rotates the power distribution unit 13 of the power distribution unit 100 by itself, so that the distribution efficiency is very high and the cooling efficiency is improved by the natural cooling method that does not use a separate cooling device. By falling down naturally into the grinding part 200 without grinding, it is pulverized by the vertical screw 14, which not only has high grinding efficiency but also has a simple structure and can be miniaturized and lightened, and can be used not only with green beans but also with roasted coffee beans. The effect is very excellent invention.
