In general, coffee drinks made using coffee beans are classified into instant coffee and coffee beans, and coffee beans are divided into drip and espresso according to the extraction method from coffee beans. Espresso is a high-pressure hot water supply. As a way of extracting the coffee juice in a short time, it can be easily extracted through the espresso coffee extraction device.
That is, among the various types of coffee sold in the coffee shop, the main raw material is espresso, and the apparatus for extracting espresso coffee includes a filter unit for accommodating crushed coffee beans and extracting coffee (Porta filter: Porta). Filter), a boiler for supplying hot water, and a pump for supplying the hot water to coffee beans.
In addition, there are kinds of coffee beans, roasted coffee beans, grain size, etc., which determine the flavor and taste of espresso when extracting the espresso, and in particular, the hot water when extracting the espresso coffee from the coffee extracting device. Temperature and pressure also have a big impact.
A well known example of a beverage maker suitable for making a beverage based on the interaction between the beverage extract and the extraction fluid is an espresso apparatus (coffee extractor), which conventionally has forced the hot water to flow through a certain amount of ground coffee. The espresso apparatus has an extraction chamber (basket) containing a so-called porter filter in which the actual espresso manufacturing process occurs during the operation of the instrument.
Conventional coffee extractors use a single basket (extracting chamber including a port filter) to compress coffee powder when it is introduced, extracting the coffee solution, and then discharging coffee grounds in one basket. The drawback was that the progress of the extraction was very slow.
In other words, registration No. 20-0225910 (Full Automatic Coffee Extraction Device), filed on December 23, 2000 and registered on March 21, 2001, supplies hot water after heating-grinding or grinding roasted coffee beans or raw roasted coffee beans. Fully automatic coffee extracting apparatus that performs the entire process of extracting coffee by one machine electrically and mechanically, as shown in Figure 1, the outer case 41 is one side is separated, the drip 42 and the port ( A space portion 44 is formed to accommodate 43 therein, and a pair of support jaws 45 are formed on the ceiling of the space portion 44 to hold the upper end of the drip 42 in a port. A support 46 supporting the 43 is provided, and the exterior case 41 is provided with a switch 47, a water inlet 48, a shell recovery port 49, and a water tank 50, and an exhaust port on the upper surface thereof. 51 and the green bean inlet 52 are provided.
Therefore, in the conventional coffee extractor, the coffee powder is extracted by extracting the coffee powder by using one basket, and the coffee grounds are discharged.

The present invention is to solve such a conventional drawback, the object of the present invention is to configure the coffee compression and basket rotation operation by using a single motor, coffee powder compression and coffee juice extraction and waste discharge This is to provide a coffee extractor to be done at the same time.

According to the present invention, when three powders are included in a cylinder and coffee powder is introduced into one basket, the basket is rotated while the piston is moved upward, and the piston is lowered again to compress and extract coffee from the two baskets and discharge the grounds. This is to provide a coffee extractor to be done at the same time.

That is, to provide a coffee extractor composed of one motor, a piston, a cylinder, and an upper key lock lock to simultaneously perform coffee inflow, coffee compression (stock extraction), and waste discharge through three baskets rotated by 120 degrees. .

The present invention for achieving the above object is characterized in that it is configured so that the rotating motion of the rotating cylinder and the rotating cylinder of the piston is selectively made by a single motor.

The present invention is characterized in that the compression of the coffee, extraction of the coffee liquor, and the discharge of the ground are simultaneously performed by rotating the three baskets and the shanghai-dong of the gear and the piston by one motor drive.

According to the present invention, when the upper key lock lock is coupled to the piston and the piston is moved upward, the piston gear does not rotate, and when the piston gear moves downward, the upper key module is lowered by the pusher while the end of the upper key lock locks down. Characterized in that the main gear and the piston gear is connected to rotate.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

According to the present invention, one motor (M) is provided, and the gear (2) rotated in engagement with the drive gear (1) of the motor (M) and the gear (3) in engagement with the cylinder (4) rotate on one shaft ( 30 is installed at the upper end of the shaft 30, and the piston gear 5 rotates in engagement with the piston gear 6 of the piston 7 so that the inserting portions 7a and 7b of the piston 7 are moved into the cylinder ( It is configured to be inserted into or removed from the basket of 4), the lower portion of the slide module 10, the nozzle (9) moving by the nozzle linker 8 is configured to be detachable to the lower cap 21, the slide module The upper catching portion 22 and the lower catching portion 23 are fixed to the upper and lower ends of the 10 so as to move the nozzle linker 8 up and down, and the push rod 11 is fixed to the slide module 10 and slides. When the module 10 rises, the upper key lock lock 12 pushes up the upper key module 13 to release the driving force of the upper key module 13 and at the same time the lower key module 18 Raising the lower side when the reverse check key 19 is configured to transmit the driving force to the cylinder (4)

The operation of the present invention configured as described above will be described.

In the present invention, the ground coffee powder is first introduced into one of the three baskets of the cylinder (4).

Here, the cylinder (4) includes three baskets, and the three baskets are rotated by 120 degrees, the coffee injection, coffee compression, coffee discharge is made at the same time.

That is, when power is applied and the motor M is driven, the shaft 30 rotates by the rotation of the gear 2 engaged with the drive gear 1, and the gear 3 rotates to rotate the cylinder 4 by 120 degrees. Let's do it.

At this time, the piston (7) is raised and positioned at the highest point, the slide module (10) rises with the piston (7) and releases the lock by hitting the upper key lock lock (12) of the upper key module (13) Since the module 13 is raised to block the driving force to the piston gear 5, the piston drive gear 5 does not rotate even when the shaft 30 rotates.

Further, when the upper key striker 17 rotates against the first upper key lock 15 while the upper key striker 17 rotates with the upper key by the reverse rotation of the motor M drive gear 1, the second upper key lock 16 is rotated. As the lock is released, the upper key module 13 supported by the slide block 14 falls down.

Therefore, the driving force is transmitted to the piston gear 5, and when the upper key module 13 is lowered and the driving force is transmitted, the upper key striker 17 is located on the upper side while being pressed against the piston gear 5. Since the upper key lock 15 is not hit, there is no collision, thereby preventing shock force transmission and noise.

In addition, when the gear 2 is rotated by the reverse rotation of the motor M drive gear 1, the shaft 30 rotates in reverse and the piston gear 6 rotates so that the piston 7 descends and the coffee is compressed.

At this time, the slide module 10 is also lowered together, and the slide module 10 {the piston 7 and the slide module 10 are integrally fastened together and raised or lowered together} so that the nozzle linker 8 strikes down. The nozzle 9 is inserted into the lower cap 21.

In addition, when the lower key module 18 reversely rotates the motor M drive gear 1, the lower check key 19 moves toward the lower check key fixing spring 20 to block transmission of power to the gear 3. As a result, the cylinder 4 does not rotate.

Therefore, hot water flows into the nozzle 9 and passes through the compressed coffee, and the coffee extracted to the upper portion of the piston compression rod is discharged to the outside.

On the other hand, the shaft 30 is rotated by the rotation of the gear 2 by the forward rotation of the motor drive gear 1, the piston gear 6 is rotated to raise the piston (7).

At this time, the lower check key 19 is separated from the gear 3 does not transmit the driving force, the cylinder 4 does not rotate until the piston 7 is raised to the highest point.

In addition, the slide module 10 is raised by the rise of the piston 7 and the lower locking portion 23 hits the nozzle linker 8 upward, so that the nozzle 9 is separated from the lower cap 21.
When the piston 7 is at the highest point while the slide module 10 is raised with the piston 7, the upper key module 13 is released by hitting the upper key lock lock 12 of the upper key module 13 to release the lock. ) To block the driving force to the piston gear (5), and when the piston (7) is located at the highest point, the lower check key (19) engages with the gear (3) and starts the reverse rotation, the power is transmitted to the cylinder ( Rotate 4) 120 degrees so that the extracted coffee grounds are in the outlet position.

When the upper key striker 17 rotates by hitting the first upper key lock 15 while the upper key striker 17 rotates in reverse with the upper key by the reverse rotation of the motor drive gear 1, the locking of the second upper key lock 16 is released. When the upper key module 13 supported by the block 14 falls down and the driving force is transmitted to the piston gear 5, the upper key module 13 is lowered and the upper key striker when the driving force is transmitted. Since the 17 is pressed against the piston gear 5 and positioned upward, the 17 does not hit the first upper key lock 15 so that there is no collision, thereby preventing transmission of impact force and suppressing noise.

In addition, when the gear 2 rotates due to the reverse rotation of the motor drive gear 1, the shaft 30 rotates in reverse, the piston gear 6 rotates and the piston 7 descends, and the piston 7 descends. Press the basket guide pin 26 by the lower cap 21 is lowered while the coffee grounds are separated from the basket.

When the shaft 30 is rotated by the rotation of the gear 2 by the forward rotation of the motor drive gear 1, the piston gear 6 rotates to raise the piston 7, and the cap guide pin lock 25 is the basket guide pin. Hook (26) and pull the lower cap 21 up.

When the lower cap 21 is raised to the designated position, the hook is released and the piston 7 is raised while meeting the cap guide pin lock 25 termination section T of the piston lock guide 24.

As the above operation is repeatedly performed, coffee extraction is performed quickly.
