Description

Coffee machine equipped with electronic recording means for coffee beans {COFFEE MACHINE HAVING ELECTRONIC RECORD MEANS FOR BEANS}

The present invention relates to a coffee machine having electronic recording means associated with coffee beans.

Recently, as interest and demand for coffee has increased, the demand for coffee machines is also increasing. There are two types of coffee machines: capsule-type coffee machines and ground coffee-type coffee machines. The capsule-type coffee machine is a device that grinds coffee beans and makes them into capsules, and then extracts coffee using them. However, the capsule type has a disadvantage that taste and freshness are deteriorated because it is extracted into coffee only after a considerable time has passed after the coffee is ground. On the other hand, since the coffee bean type coffee machine directly grinds roasted beans and extracts coffee directly, it has excellent taste and freshness.

The coffee bean type coffee machine is provided with a bean container for storing coffee beans. In general, the bean container is inserted in the upper part of the coffee machine, and when all the beans put inside are consumed, the beans are reinserted and used. The conventional bean container is formed of a plastic material having a certain rigidity. Therefore, if all the beans are consumed, the bean container is used as it is without replacing it. On the other hand, the input coffee beans are separately packaged and distributed and sold. Therefore, in order to add coffee beans, the coffee beans must be added to the bean container after removing the packaging material of the coffee beans.

The conventional coffee bean type coffee machine does not have a function of grasping the amount of coffee beans put into the coffee bean container and the amount of beans used. For this reason, information on how many additional cups can be extracted after a new coffee bean is added cannot be provided to the user, causing inconvenience in use.

1 is a diagram illustrating a coffee machine 200 to which a bean container 100 is combined according to an embodiment of the present invention.

Two bean containers 100 are coupled to the top of the coffee machine 200. Roasted beans (not shown) are stored in the bean container 100. The coffee machine 200 grinds the beans stored in the bean container 100 to form a powder, and extracts the coffee liquid by using high temperature and high pressure water from the powder brewer (not shown). do. The extracted coffee liquid is supplied through a nozzle 220 disposed in front of the coffee machine 200.

The coffee machine 200 may adjust the amount of coffee beans stored in the bean container 100 according to the type of coffee beverage to be produced. For example, when the user selects 1 cup of Americano or 1 cup of espresso, the weight of the beans to be used may be determined differently. In addition, the coffee machine 200 may vary the amount of extraction even in the case of the same coffee beverage. For example, even in the case of the same Americano, the amount of extraction can be divided into large, medium, and small according to the user's selection.

A plurality of buttons 222 may be provided on the front of the coffee machine 200. The user can select the type and amount of the beverage by using the button 222. In addition, a display 210 may be provided on the front of the coffee machine 200. The display 210 may display information about the type, remaining amount, and beverage processing process of the selected coffee beverage.

The coffee machine 200 illustrated in FIG. 1 is illustrated as a combination of two bean containers 100 having the same shape and size, but the coffee machine 200 may be provided with one or three or more bean containers 100. Of course you can.

2 is a diagram illustrating a bean container 100 according to an embodiment of the present invention.

Referring to FIG. 2, the bean container 100 according to the present embodiment is integrally manufactured by blow molding using a plastic material. Blow molding is a plastic manufacturing method in which a melted mass of thermoplastic resin is injected with air and expanded into a mold shape to form an outer body. Blow molding is mainly used to make hollow shapes with thin walls like plastic bottles. Blow molding includes extrusion blow molding, injection blow molding, or injection stretch blow molding, and the bean container 100 according to the present embodiment may be manufactured by one of the above three methods.

As the material of the bean container 100, at least one of polyethylene terephthalate (PET), polyacrylonitrile (PAN), polyvinyl chloride (PVC), polypropylene (PP), and paper may be used. Among them, PET has an advantage in that the amorphous polymer has a wide range of thermoplastic properties, so that it is easier to mold than the partially crystalline PP. In addition, the bean container 100 may be made of a transparent material, whereby the amount of beans remaining inside can be easily determined.

The bean container 100 has a thickness of about 0.1 to 0.9mm. Therefore, when a certain or more external force is applied, the shape of the bean container 100 may be deformed.

The bean container 100 has a hollow cylindrical shape having a container inlet 102, and includes an upper surface 108, a side surface 110, an inclined surface 106, and a container inlet 102. The top surface 108, the side surface 110, the inclined surface 106, and the container inlet 102 forming the bean container 100 are integrally formed by blow injection.

The top surface 108 of the bean container 100 may be formed flat. Therefore, when transporting the bean container 100, the upper surface 108 can be placed on the floor. An air vent hole 116 corresponding to a through hole may be formed in the upper surface 108.

The side surface 110 is a surface formed by vertically descending from the edge of the upper surface 108 and may be generally formed in a circular shape. Air vent holes 116 corresponding to through holes may also be formed on the side surface 110.

The inclined surface 106 corresponds to a surface formed to be partially inclined at the lower end of the side surface 110. By the inclined surface 106, the bean container 100 has a shape in which the diameter decreases toward the container inlet 102. Therefore, all the beans put into the bean container 100 by the inclined surface 106 can be concentrated in the direction of the container inlet 102. Air vent holes 116 corresponding to through holes may be formed on the inclined surface 106 as well.

The container inlet 102 is formed at the lower end of the bean container 100 and has a hollow cylindrical shape. And both the upper and lower ends of the container inlet 102 has an open structure. The container inlet 102 corresponds to a portion that is coupled to the coffee machine 200. And all the beans put into the container inlet 102 are discharged to the coffee machine 200 through the container inlet 102. An air vent hole 116 corresponding to a through hole may be formed in the container inlet 102 as well.

The upper end of the container inlet 102 may be closed by the protective film 118. The protective film 118 may be formed of a material (for example, an aluminum thin film) that can be relatively easily crushed by an external force as a thin film type film. When the container inlet 102 is inserted into the coffee machine 200, the protective film 118 may be torn by the insertion member 230 provided inside the coffee machine 200, whereby the coffee beans It may be discharged to the coffee machine 200 through the inlet 102.

The air vent hole 116 corresponds to a through hole that can be formed at any place of the container inlet 102. That is, the air vent hole 116 may be formed through any one of the top surface 108, the side surface 110, the inclined surface 106, and the container inlet 102 of the bean container 100. The diameter of the air vent hole 116 may be formed as small as about 1 mm. The air vent hole 116 corresponds to a passage that communicates the inside and the outside of the sealed bean container 100. Therefore, before the protective film 118 is removed, the air vent hole 116 becomes the only passage in communication with the outside. Air inside the bean container 100 may be discharged to the outside through the air vent hole 116, and air from the outside may be introduced into the inside. For this reason, it is possible to maintain the taste and aroma of coffee beans roasted in the bean container 100 for a long time.

A check valve 130 may be coupled to the air vent hole 116. The check valve 130 allows the fluid to flow in only one direction. Therefore, in this embodiment, while the check valve 130 allows air inside the bean container 100 to be discharged to the outside, it is possible to block the air from outside the bean container 100 from flowing into the inside. By blocking the inflow of outside air by such a check valve 130, the roasted coffee beans can be stored for a long time, and gas generated from the roasted coffee beans can be discharged to the outside of the bean container 100. .

The check valve 130 may be made of rubber or silicone, and is not limited by its shape and structure.

Two or more air vent holes 116 may be formed in the bean container 100. That is, when the volume of the bean container 100 is large and the amount of coffee beans inserted therein is large, two or more air vent holes 116 may be formed.

The bean container 100 according to the present embodiment has been illustrated to have a cylindrical shape and a truncated cone shape, but the present invention is not limited by the shape of the bean container. Therefore, it goes without saying that the bean container 100 according to another embodiment of the present invention may have various shapes such as a square pillar and an oval-shaped pillar.

3 and 4 are a front view and a plan view illustrating the insertion member 230 into which the bean container is inserted.

3 and 4, the insertion member 230 is disposed to protrude upward in the interior of the accommodation space into which the coffee bean container 100 is inserted in the coffee machine 200. And the upper end of the insertion member 230 is formed to be pointed. Therefore, the protective film 118 attached to the container inlet 102 is torn by the pointed end of the insertion member 230 in the process of inserting the bean container 100 into the coffee machine 200. The protective film 118 is torn so that the coffee beans in the bean container 100 may be discharged into the coffee machine 200.

The insertion member 230 has four blades 234. The four blades 234 are disposed at 90 degrees apart from each other. An empty space 232 is formed between the blade 234 and the blade 234, and the beans discharged from the bean container 100 may flow into the inside of the coffee machine 200 through the empty space 232. .

The diameter of the insertion member 230 may be formed somewhat smaller than the inner diameter of the container inlet 102. For this reason, excessive force may not be required in the process of inserting the insertion member 230 into the container inlet 102. Of course, when the diameter of the insertion member 230 is much smaller than the inner diameter of the container inlet 102, it may affect the discharge of coffee beans. Therefore, the diameter of the insertion member 230 may be formed to about 70 to 95% of the inner diameter of the container inlet 102.

The bean container 100 according to the present embodiment can be removed from the coffee machine 200 without reuse after all the beans input therein are used. And the new bean container 100 can be re-coupled to the coffee machine 200 and used. As described above, the bean container 100 according to the present embodiment has an advantage of being convenient to use because it is not only circulated by itself without a separate packaging material, but also can be directly coupled to the coffee machine 200 and used.

5 is a block diagram illustrating a configuration of a coffee machine 200 that processes information received from the bean container 100.

Referring to FIG. 5, an electronic recording means 120 may be attached to the outer surface of the bean container 100. The electronic recording means may correspond to an electronic tag (RFID), a USB memory, a magnetic card, or an integrated circuit (IC) card. The electronic recording means 120 stores information on the origin, product name, roasting date, manufacturing date, shipping date, storage period, weight, and the number of remaining available for sale, that is, information on the coffee beans stored in the bean container 100. Can include. In addition, the coffee machine 2000 may store information in the electronic recording means 120.

The coffee machine 200 may include an information transmission/reception unit 212 capable of reading information stored in the electronic recording means 120 and storing the information in the electronic recording means 120. The information on the bean container 100 read by the information transmitting and receiving unit 212 is transmitted to the processing unit 214. In addition, the result processed by the processing unit 214 may be stored in the electronic recording means 120 through the information transmission/reception unit 212.

The processing unit 214 may display information received from the information transmission/reception unit 212 through the display 210. For example, the processing unit 214 may display information on the origin of the coffee beans stored in the bean container 100, the product name, the roasting date, the storage period, the number of remaining available for sale, and the product identification number through the display 210. have. In addition, the processing unit 214 determines that a new bean container 100 is installed in the coffee machine 200 or that the existing bean container 100 has been removed, using the information received from the information transmission and reception unit 212, and displays it ( 210) can be displayed.

The processing unit 214 may reflect the result processed by the coffee machine 200 from the information received from the information transmission/reception unit 212 and then display the result through the display 210. For example, the processing unit 214 uses information on the weight of coffee received from the information transmission and reception unit 212 and information on the amount of extraction received from the extraction unit (not shown) of the coffee machine 200, and can be extracted in the future. The number of times, that is, the remaining available for sale may be displayed through the display 210. In addition, the processing unit 214 may control the extraction of the coffee liquid through the extraction unit to not proceed when the accumulated sales volume for the coffee bean container 100 reaches a certain number of times and display it through the display 210.

The processing unit 214 may recognize when a new bean container 100 is mounted using the information stored in the electronic recording means 120, identify the remaining available for sale, and display it through the display 210.

Information corresponding to the result processed by the processing unit 214 may be stored in the electronic recording means 120 through the information transmission/reception unit 212. For example, the processing unit 214 may store the remaining amount obtained by subtracting the extraction amount processed so far in the electronic recording means 120, and in particular, the remaining amount reflecting the extraction amount each time the extraction amount occurs in the electronic recording means 120. have. In addition, the information transmission/reception unit 212 may read the remaining amount stored in the electronic recording means 120 and transmit it to the processing unit 214, and the processing unit 214 may display information on the remaining amount through the display 210. For this reason, even when the electronic recording means 120 and the coffee bean container 100 are mounted on different coffee machines 200, it is possible to accurately calculate the remaining available sales.

The coffee machine 200 according to the present embodiment is illustrated as having an electronic recording means 120 capable of transmitting and receiving data to and from the coffee machine 200 in one or both directions. However, the present invention may include a sensing means that stores information on the coffee bean container 100 but does not receive information from the coffee machine 200. For example, the bean container according to another embodiment of the present invention uses any one of a bar code, a magnet tape, or a QR code as a sensing means instead of the electronic recording means 120. And, the coffee machine may be provided with a reader (not shown). Barcode, magnetic tape, or QR code stores information on the bean container, such as product number (product production number, etc.), weight, type, roasting date, number of available sales, storage period, country of origin, etc. Can be. The reader can read information stored in barcodes, magnetic tapes, or QR codes and display them through the display.

The coffee machine can recognize that a new coffee bean container has been inserted by means of detection means such as barcodes, magnetic tapes or QR codes. In addition, the coffee machine can read and utilize information of the bean container stored in a sensing means such as a barcode, a magnetic tape or a QR code (for example, the weight of the bean, the type, the storage period of the roasting date, the place of origin, etc.). When the sensing means is a barcode, a magnetic tape or a QR code, the coffee machine may be provided with a reader capable of reading them.

Another type of sensing means capable of detecting that a coffee bean container has been inserted may have various shapes and configurations. For example, a magnetic method, a switch method, an infrared sensor method, or the like can be used as the sensing means.

The magnet method may adopt a configuration in which a permanent magnet is attached to a bean container and a reed switch is attached to a coffee machine, for example. When a bean container with a permanent magnet is inserted into the coffee machine, the reed switch can recognize it.

The micro switch method (or limit switch method) is a structure in which a protrusion provided in a bean container or a bean container presses the micro switch. The coffee machine can recognize that the coffee bean container is inserted when the micro switch is pressed.

In the infrared sensor method, a shape that responds to a specific signal from an infrared sensor is processed into a bean container and then a different wavelength of the infrared sensor is used to detect that the bean container is inserted.

As such, it can be seen that the coffee machine according to the present exemplary embodiment can use various types and configurations in addition to the above-mentioned configuration as a sensing means capable of detecting that a bean container is inserted.
