Figure 1 shows the overall shape of a portable coffee machine according to an embodiment of the present invention, Figure 2 shows an exploded view of a portable coffee machine according to an embodiment of the present invention, Figure 3 is an embodiment of the present invention It is an enlarged view of an extraction part of a portable coffee machine according to an example.

1 to 3, the portable coffee machine 100 according to an embodiment of the present invention includes a body portion 110, an extraction portion 120 and / or a power supply unit 130.

Inside the main body 110, an accommodation space and an extraction unit 120 in which water can be accommodated are installed, and a power supply unit 130 is installed outside.

More specifically, the main body 110 includes an input unit 111 that controls the operation of the extraction unit 120 and a cover unit 112 that seals the main body 110.

Meanwhile, a boiler that heats water may be installed in the accommodation space. The boiler is supplied with power by the power supply unit 130 in a heating method using an electric heater, and is controlled by the input unit 111.

The input unit 111 is installed on the outer surface of the body unit 110 and receives electric energy from the power supply unit 130. More specifically, the input unit 111 is formed of a plurality of buttons for transmitting a control command to the extraction unit 120, the plurality of buttons is an espresso button (ESPRESSO BUTTON), a tea espresso button (TEA PRESSO BUTTON) and / or It is a hot water button (HOT WATER BUTTON).

For example, when the user presses the espresso button, a command to extract the coffee stock solution from the coffee material within 30 seconds may be transmitted to the extraction unit 120, and when the tea press button is pressed, the coffee stock solution is extracted from the coffee material within 25 seconds. A command can be transmitted, and when a hot water button is pressed, a command for extracting hot water by heating water can be transmitted.

Here, the button may be a pressurized button or an electrostatic button.

Here, the coffee material is not limited to coffee beans, and herbal tea, green tea, and black tea may be used.

Meanwhile, the input unit 111 may include a safety button that immediately stops the operation of the extraction unit 120.

The safety button may immediately stop the operation of the extraction unit 120 when an error occurs in the extraction unit 120 to prevent damage or damage to the device.

The cover portion 112 is installed on the top of the body portion 110 to seal the body portion 110 so that water contained in the accommodation space or coffee material stored in the coffee storage portion 121 does not flow out.

On the other hand, a detection sensor may be installed on the cover portion 112, and the detection sensor may detect that a gap or a space between the cover portion 112 and the body portion 110 is generated and generate a limit command. . In addition, the detection sensor transmits a limit command to the input unit 111, and the input unit 111 may have an input function limited according to the limit command.

That is, the detection sensor prevents the extraction unit 120 from being operated through the input of the input unit 111 in a state where the body unit 110 is not completely sealed, so that a gap between the body unit 110 and the cover unit 112 is prevented. Alternatively, water spaced in the accommodation space or coffee material accommodated in the extraction unit 120 may be prevented from being ejected to the outside.

The extraction unit 120 is formed with an internal space in which coffee material can be accommodated. In addition, the extraction unit 120 is installed in communication with the main body 110 and extracts the coffee stock solution using the vapor pressure of water regardless of the type of coffee material.

More specifically, the extraction unit 120 includes a coffee storage unit 121, a cover unit 122, and a brewer 123.

The above-described extraction unit 120 is electrically connected to the input unit 111 to receive a control command from the input unit 111 and receives power from the power unit 130.

The coffee storage unit 121 is formed with an interior space in which coffee materials can be accommodated. The coffee storage unit 121 may be provided in the form of a capsule and is installed on the top of the body unit 110 to be detachable from the body unit 110.

In addition, a discharge port 121a may be formed at the bottom of the coffee storage unit 121, and the discharge port 121a is formed of a mesh filter, so that the extracted coffee stock solution is discharged and remains in the coffee storage unit 121. The coffee ingredients to be filtered can be filtered out.

The above-described coffee storage unit 121 has an advantage in that it is detachable and convenient to maintain. In addition, the coffee storage unit 121 may be mounted on a commercially available capsule coffee in a detached position.

Meanwhile, the coffee storage portion 121 may be bisected in the vertical direction and may be combined in the vertical direction.

For example, when the coffee storage unit 121 is washed after the coffee extraction is completed, the coffee residue remaining in the coffee storage unit 121 can be more easily removed by detaching the coffee storage unit 121 and separating it in the vertical direction. There are advantages.

On the other hand, the coffee storage portion 121 may be formed with a groove having a diameter of 38mm and / or 44mm, which is the same size as a dedicated standard for pod coffee and / or hard pod (ESE POP).

When the pod coffee is accommodated in the coffee storage unit, the pod coffee is fixed to the groove without being separated, so that the coffee stock solution can be extracted evenly from the front surface of the pod coffee during extraction.

The coffee storage unit 121 receives heated water from the accommodation space. More specifically, when the water accommodated in the accommodation space is heated, steam is generated to generate pressure in the accommodation space, and the water heated by the pressure rises to the coffee storage unit 121. Thereafter, when heated water seeps into the coffee material particles and the soluble component dissolves, the dissolved component is eluted out of the coffee material particles, and a coffee stock solution is produced.

The cover part 122 is detachably coupled to the top of the coffee storage part 121 to prevent the coffee material contained in the coffee storage part 121 from flowing out. The cover part 122 may be provided with a mesh filter, and the mesh filter may be made of stainless steel and the mesh spacing may be formed smaller than particles of ground coffee beans.

According to such a mesh filter, coffee material or coffee grounds which are not extracted or extracted and remaining coffee material are prevented from flowing out, and the extracted coffee stock may be transferred to the brewer 123 through the mesh filter.

On the other hand, the center of the mesh filter of the cover portion 122 may be formed with a narrow gap, and may have a wider gap toward the edge.

For example, steam and heated water rising from the accommodation space due to pressure are transmitted around the center of the mesh filter. In this case, when the pressure applied to the center increases, the coffee material may be ejected through the center when the interval between the centers is wide.

Therefore, it is possible to prevent the coffee material from being ejected by reducing the pressure applied to the center by narrowing the gap between the centers of the mesh filter and widening the edges.

On the other hand, the lower end of the cover portion 122 may be formed with a sharp protrusion at the end. When the cover portion 122 is combined with the capsule coffee, the protrusion portion of the cover portion 122 pierces the upper end of the enclosed capsule coffee to form a capsule coffee. A hole is formed at the top and water heated into the capsule coffee is introduced into the hole, so that the coffee stock solution can be extracted and the extracted coffee stock solution can be moved.

The brewer 123 communicates with the coffee storage portion 121 and the cover portion 122 to form a passage through which the coffee stock solution extracted from the coffee storage portion 121 moves and is detachably coupled from the cover portion 122. In addition, a pillar portion 123a is formed at the center of the brewer 123, and the ends of the pillar portions 123a are finished with a stainless steel mesh filter, but mesh than the mesh filter provided in the coffee storage portion 121 and the cover portion 122 It may be provided with a mesh filter having a narrow gap.

On the other hand, the brewer 123 may be formed with a groove similar to the diameter of the cover portion 122 at the bottom so that the cover portion 122 can be coupled, and a rubber packing may be installed between the cover portion 122 and the groove. have.

The above-described rubber packing may be prevented from leaking coffee material, coffee stock, and / or steam contained in the body portion 110 and / or the coffee storage portion 121 between the brewer 123 and the cover portion 122.

The mesh filter that ends the pillar portion 123a is formed such that the mesh spacing is smaller than the particle size of the water, or is formed to a size such that the liquid cannot escape the filter due to the surface tension of the liquid, and the water accommodated in the receiving space is heated. The generated steam is permeated, but the inside of the coffee material and the coffee stock solution is prevented from being ejected.

On the other hand, when the steam generated in the receiving space is discharged to the pillar portion 123a formed in the center of the brewer 123, the passage from the brewer 123 to the pillar portion 123a is gradually narrowed, so that the discharge rate of steam is increased. As the speed increases rapidly and the speed increases, the pressure inside the receiving space decreases.

This principle is Bernoulli's principle that the velocity decreases when the fluid pressure is high and the velocity increases when the fluid pressure is low.

When the pressure in the interior space is reduced through the above-described process, the coffee stock solution, which was raised by the pressure, stops rising and goes back to the receiving space.

On the other hand, a plurality of protrusions may be formed in the interior of the pillar portion 123a, and these protrusions may be installed to be spaced apart from each other in a direction looking at the bottom end of the pillar portion 123a.

When the coffee stock solution is raised or lowered to the above-mentioned pillar part 123a, it collides with the protrusion and mixes. Through this process, the difference in the concentration of the coffee stock solution caused by the difference in extraction time can be reduced.

In more detail, when extracting the coffee stock solution, the concentration of the coffee stock extract from the coffee material is high at the beginning of the extraction time, but at the end of the extraction time, only the remaining coffee grounds remain and the concentration of the coffee stock extract is lowered. The difference between the concentration of the coffee stock solution caused by the difference in extraction time can be reduced because the coffee stock solution and the rising coffee stock solution collide with the protrusions.

On the other hand, at the bottom of the brewer 123, a radial partition wall from the center may be formed at regular intervals, and the coffee stock that has been raised to the brewer 123 collides with the radial partition wall and mixes, thereby forming a protrusion formed in the above-described pillar portion 123a As described above, it is possible to reduce the difference in concentration of the coffee stock solution caused by the difference in extraction time.

For example, the radial partition wall may be provided in a form in which the end is bent. When the end is provided in a bent form, the collision area colliding with the coffee stock solution is widened, and the coffee stock solution may be more evenly mixed.

On the other hand, when the extraction unit 120 is detached, only the hot water button is operated in the input unit 111 to be used for heating and heating only water.

The power supply unit 130 supplies power to each configuration so that the installed boiler and the input unit 111 of the body unit 110 are operated and is installed at the bottom of the body unit 110.

The power supply unit 130 may be connected to the power supply through a cable line so that electric energy can be supplied from the outside.

For example, a household socket 131 and a vehicle socket 132 are installed in the power supply unit 130, and electric energy can be supplied from the outside through the household socket 131 or a vehicle socket.

The above-described home socket 131 is an AC 220V adapter, and the vehicle socket is a DC 12V adapter.

Meanwhile, the power supply unit 130 may be provided to be self-charging, for example, a solar panel may be provided to charge the power using sunlight, and may be installed on the side of the body unit 110.

The power supply unit 130 is not necessarily limited to a solar panel, but may be provided as an energy harvesting module capable of absorbing electromagnetic waves and collecting and generating energy.

According to the above-described portable coffee machine including the main body 110, the extraction unit 120, and the power supply unit 130, the coffee stock solution can be extracted using the vapor pressure of water regardless of the type of coffee material.
