Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a coffee extractor for automatically extracting coffee liquid after grinding coffee beans.

BACKGROUND OF THE INVENTION In recent years, coffee extractors that extract coffee liquid after grinding coffee beans have been required to reduce noise when grinding coffee beans.

Conventionally, this type of coffee brewer generally had a configuration as shown in FIG. The configuration will be explained below.

As shown in the figure, a grinding chamber 15 is used to put coffee beans and grind them. When the power is turned on, a cutter 17 is rotated by a motor 16, and the coffee beans are sequentially ground into coffee powder. On the other hand, the ground coffee powder passes through a filter 18 provided in the grinding chamber 16 and is accumulated in a filtration chamber 19. When the grinding of the coffee beans in the grinding chamber 15 is completed, electricity is started to be applied to the heating element 2o by a timer or the like, and the water in the water container (not shown) turns into boiling water and flows into the upper part of the filtration chamber 19. It is poured into the coffee powder through the outlet 21, extracts the coffee components, becomes a coffee liquid, and is poured into the glass container 2.
Drip into 2.

Problems to be Solved by the Invention In such a conventional coffee extractor, when grinding coffee beans, the cutter 17 is rotated after all the coffee beans are stored in the grinding chamber 15, so the coffee beans that come into contact with the cutter 17 are However, other coffee beans are not ground but are stirred and moved within the grinding chamber 15. Therefore, the sound before stirring the coffee beans was louder than the sound of grinding the coffee beans by the cutter 17, and it was very noisy.

The present invention solves the above-mentioned problems, and aims to eliminate the need for stirring coffee beans and to efficiently grind the coffee beans.

Means for Solving the Problems In order to achieve the above object, the present invention includes a water container, a heating element for heating the water in the water container, and a crushing chamber incorporating a cutter driven by a motor. A means for solving the problem is to provide a bean storage chamber which is connected to the grinding chamber and has an opening in a portion facing the cutting blade of the cutter.

Effect of the Invention The present invention uses the above-mentioned problem-solving means to continuously supply coffee beans little by little to the cutting blade of the cutter through the opening provided in the part of the bean storage chamber facing the cutting blade of the cutter. The coffee beans in the bean storage room are hardly agitated, and almost no sound is generated. However, since the supplied coffee beans contact only the cutting edge at the tip of the cutter, the variation in particle size of the ground coffee powder is extremely small.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2.

As shown in the figure, the crushing chamber 1 houses a cutter 3 that is rotationally driven by a motor 2, and the tip of the cutter 3 is bent upward to form a cutting blade 4. A bean storage chamber 5 with an inclined bottom for storing coffee beans is connected to the grinding chamber 1, and a bean storage chamber 5 is provided below the bean storage chamber 5 at a portion facing the cutting blade 4 of the cutter 3. is provided with an opening 6 through which the coffee beans pass, through which the coffee beans in the bean storage chamber 5 are guided into the grinding chamber 1.

On the other hand, a filter 7 is provided on the opposite side of the bean storage chamber 5 of the grinding chamber 1.
It is equipped with a filtration chamber 8.

The lid 9 is the crushing chamber 1. The upper openings of the bean storage chamber 6 and the filtration chamber 8 are closed. The heating element 1Q heats the water in the water container 11, and the hot water heated by the heating element 10 is dripped into the filtration chamber 8 from the discharge port 12.

To explain the operation in the above configuration, when coffee beans are stored in the bean storage chamber 5, the coffee beans are pushed downward along the inclined bottom, and a small amount of coffee beans spills out into the grinding chamber 1 through the opening 6. However, most of it accumulates in the bean storage chamber 5. After that, when the lid 9 is closed and the power is turned on, the motor 2 and cutter 3 will rotate at high speed. At this time, the rotational vibrations of the motor 2 and cutter 3 are also transmitted to the coffee beans in the bean storage chamber 5, and the coffee beans spill out into the grinding chamber 1 from the opening 6 little by little due to the minute vibrations. On the other hand, since the cutting blade 4 of the cutter 3 is disposed close to the opening 6 and the cutter 3 is rotating at high speed 7, the coffee beans spilling out from the opening 6 are removed from the cutter 3.
It comes into contact with the cutting blade part 4 of the coffee table, and is crushed into coffee powder.

The coffee powder pulverized by the cutting edge 4 of the cutter 3 is sent to the filter 7 by the rotational force of the cutter 3, and is stored in the filtration chamber 8.

When the grinding of coffee beans is finished, electricity is started to be applied to the heating element 10 by a timer or the like, and the water in the water container 11 is heated in the heating pipe 13. As the internal pressure within the heating pipe 13 increases, the hot water within the heating pipe 13 is forced upward and drips into the filtration chamber 8 from the discharge port 12. The hot water dripped into the filtration chamber 8 extracts coffee components while passing through the coffee powder, and is stored in the glass container 14 as coffee liquid.

Effects of the Invention As is clear from the above embodiments, according to the present invention, a bean storage chamber is provided that is connected to the grinding chamber and has an opening in the portion facing the cutting edge of the cutter. The entire coffee bean is not stirred, allowing extremely quiet grinding of coffee beans.

Further, since most of the coffee beans coming out of the opening are crushed by the cutting blade of the cutter, coffee powder with a uniform particle size distribution can be obtained, and delicious coffee can be extracted.
