Description

Fully automatic coffee extractor {Automatic coffee drip pot}

The present invention relates to a fully automatic coffee extracting apparatus which electrically and mechanically performs a whole process of extracting coffee by supplying hot water after heating-grinding or grinding roasted coffee beans or raw roasted coffee beans.

Conventional automatic coffee extraction device is to crush the roasted coffee beans to extract the coffee liquid, so that the roasted coffee beans (hereinafter, simply referred to as "distributed coffee beans") are purchased in advance. In this case, there is a problem in that the taste and aroma of the coffee falls if you do not use the roasted beans previously purchased for a long time. Therefore, in order to solve this problem, a coffee extractor which automatically roasts coffee beans by heating means, roasts them, pulverizes the roasted coffee beans, and pours hot water to extract coffee in one apparatus. Known as 11520. In the conventional coffee extractor, the stirring blade inside the roasting kiln is rotated in a horizontal direction about a vertical axis and roasted while stirring green beans. Therefore, the green beans were not uniformly stirred, so there was a problem that the green beans near the bottom were burned or pressed to the bottom.

In addition, the conventional coffee extractor is provided with an opening and closing shutter for opening and closing the discharge port in the horizontal direction by the solenoid in the discharge port discharged from the roasting kiln to the grinding unit. However, due to this structure, there is a problem that the switchboard is sandwiched between the opening and closing shutter and the outlet, and thus, the outlet is not completely sealed. As a result, the heat distribution is lost through the open outlet, and the green beans are not discharged or dropped into the grinder without being discharged. There was a problem that the grinding does not occur smoothly in the grinder.

And since the power distribution unit of the conventional coffee extractor is installed a separate cooling fan for cooling after distribution, the noise caused by the rotation of the cooling fan is severe and the bean shell is scattered, the inside of the machine becomes dirty, the coffee powder is introduced into the coffee powder There was a problem of deteriorating the taste.

In particular, the grinding part of the conventional coffee extractor is a pair of plate-type grinding cutters facing each other to crush the switchboards disposed therebetween, so the grinding speed is slow and the switchboard is pinched between the cutters. Therefore, grinding efficiency is low and cleaning is not easy. In addition, since the distribution head is dropped and stored in the temporary storage tank, it is transferred to the grinder by a horizontal transfer screw disposed across the temporary storage tank, which has a disadvantage in that the structure is complicated and the entire volume of the apparatus is increased.

The present invention has an object to provide a fully automatic coffee extraction device that solves the various problems of the conventional coffee extractor. In order to achieve the above object, the present invention arranges a distribution tube horizontally, and rotates the distribution tube itself about a horizontal axis so that the stirring of green beans is made smoothly as a whole. It is to increase the distribution efficiency by allowing the discharged through the hole drilled in the outer wall of the.

Another object of the present invention is to eliminate the noise and vibration by applying a natural cooling method that is cooled by idling the distribution box after the distribution is completed without installing a separate cooling blower for cooling the roasted coffee beans It is to increase the cooling efficiency while reducing the cost.

Another object of the present invention is to drop the finished coffee beans to the grinder by natural dropping method without using a separate transfer 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 extraction device by rotating to increase the grinding efficiency.

Since the raw material is put into the inside of the distribution tube 13 through the inlet to rotate the rotating shaft 18, the green beans inside the heater 15 is heated while stirring effectively by the rotation of the distribution tube 13 itself. Power distribution is achieved by Made more smoothly is stirred by a stirring blade 19 provided to protrude at a predetermined interval on the inner surface is composed of the power distribution and the overall stirred without stagnant green beans. Such rotation of the distribution tube 13 is made to rotate for a predetermined time by a timer. In this process, when the operation of the heater 15 is stopped from the time when the distribution is completed, the distribution tube 13 is a heater ( Since the operation of 15) rotates for a set time in the stopped state, natural cooling is performed without using a blower, and thus, it is possible to cool effectively in a short time without generating noise and vibration due to the installation of the blower as in the prior art. Subsequently, when the timer reaches the set time, rotation of the distribution box 13 is automatically stopped and at the same time, the solenoid 21 is operated to open and close the opening and closing door 23 about the upper hinge 22, and the power distribution and cooling are performed at the same time. The coffee beans flow down due to the inclination of the distribution box 13 and naturally fall into a grinder installed directly below it.
