Description

Portable drip coffee maker {POTABLE DRIP COFFEE MAKER}

The present invention relates to a portable drip coffee maker.

As is well known, Drip is a method of boiling coffee, pouring boiling water into coffee ground beans, and Drip Coffee is a coffee made from a Dripolator (TM) .

Such drip coffee is a coffee that is roasted and puts coffee beans in a manure apparatus and pours water thereon, and a drip brew refers to a method of making coffee in this way. Since the filter is also called a filter, drip coffee is called filter coffee in other words.

The coffee maker allows water to escape through the coffee, using only gravity. Water absorbs the oil and essence of coffee as it passes through the coffee layer. Then the water passes through the bottom of the filter, but the coffee powder does not pass through the filter, and only the liquid component that has passed through the filter falls into the container of the carafe, coffee pot, etc., and is trapped inside.

One of the advantages of a paper filter is that it has paper filters, metal filters, etc., and paper filters are widely used all over the world and can extract the coffee after it has been extracted with coffee powder. It is not necessary to clean. In addition, drip coffee made with paper filters is generally relatively clean, light, and low in sediment, but since the oil and essence of the coffee may remain in the paper filter, It may be lacking.

Metal filters are also widely used, especially in India. The metal filter is made of a thin sheet of metal with holes, allowing the coffee to pass while preventing the passing of the coffee powder. It is very useful in that you do not need to purchase a filter separately.

In addition, there are permanent plastic filters used in many coffee machines. This filter is a plastic filter in the form of a fine body, which is troublesome to manage, but it is economical and also has an advantage of being environmentally friendly.

As described above, the manufacturing method of drip coffee is the most common coffee making method which can be easily made by using a coffee maker. In addition to an automatic coffee maker, a manual drip-brewing machine is sold in the market. Manual devices are preferred because they can adjust the parameters to suit their preferences.

In addition, Drippie makers that make only one cup of small portable are also available. When a pedestal that supports the filter is placed on the cup and hot water is poured on it, the hot water immediately drips into the cup. This type of drip coffee is called hand drip or hand drip coffee, which is made by pouring hot water directly by hand. Dripper is called a dripper, and a kettle that holds downed coffee is called a server.

Other types of drip coffee using coffee pots such as other nitin flip coffee pots.

As a prior art document as a background of the invention relating to drip coffee, Korean Patent No. 10-0897948 (published on May 18, 2009) discloses an automatic drip coffee and tea making machine in which a driving means is provided for feeding a droplet nozzle horizontally A first conveying shaft, a first driving motor of the first conveying shaft, a second conveying shaft disposed perpendicularly to the first conveying shaft, a second driving motor of the second conveying shaft, a rotary motion of the first and second driving motors, A cylindrical cam which is formed on the driving shaft of the motor and which is formed with a sloped groove, and a cam shaft which protrudes from the feeding shaft and moves along the groove, And the pinion, the droplet head is moved circularly or spirally from the top of the hopper.

However, the conventional drip coffee maker as described above is burdensome to carry, and is expensive due to the use of a motor. In addition, there is a problem that drip coffee can not be used immediately without preparing a separate cup.

The tumbler 10 is generally cylindrical, such as an elongated cup, which can be drunk with extracted coffee, a screw groove 12 can be formed in the upper inner surface to be screwed with the grinder 60, A latching jaw 14 can be formed to prevent insertion of the dripper 30 inserted under the screw groove 12 into the screw groove 12.

As an embodiment of the present invention, as a recognition display for recognizing how much hot water should be poured, a separate recognition mark is displayed on a portion of the tumbler 10 having a predetermined height, or a trademark or logo of the drip coffee mug of the present invention The recognition mark 16 of the display unit 16 may be formed. It will be appreciated that if the dripped coffee is filled up to the top of the logo 16, the hot water no longer needs to be poured.

2 to 4, the dripper 30 includes a filter insertion portion 32 into which the coffee filter 20 is inserted and a flange portion 34 protruding in the middle of the filter insertion portion 32 And when the dripper 30 is inserted into the upper inner surface of the tumbler 10, the flange portion 34 is seated on the stopping jaw 14.

A ring groove 36 into which the rubber packing 2 is inserted is formed in the flange portion 34 to be seated on the engagement protuberance 14 of the tumbler 10 when inserted into the tumbler 10 to seal the inner wall of the tumbler 10 And a plurality of ventilation holes 38 are formed at predetermined intervals in the circumferential direction so that steam and heat are supplied to the ventilation holes 38 when hot water is poured to extract the coffee contained in the coffee filter 20, So that the taste of coffee can be softened.

The filter insertion portion 32 has a diameter smaller than the diameter of the tumbler 10 so as to be inserted into the tumbler 10 and can receive the coffee filter 20 to be inserted, And a plurality of support projections 31 are formed at a predetermined interval on the bottom surface of the funnel so that the dripper 30 can be raised.

Referring to Figs. 2, 3, 5 and 6, the grinder 60 includes a rotating wave part 40 rotatably and axially coupled to grind the coffee beans therein, And a main body portion 50 which is screwed to the upper surface of the tumbler 10 so that the coffee beans are collected in the dripper 30. The rotating wave portion 40 is snapped on the main body portion 50 Can be combined and separated into a losing structure.

To this end, guide grooves 41 and guide protrusions 51 are formed on the snap-fit portions of the rotary hook 40 and the main body 50, respectively. Management can be performed. In order to perform the coupling and separation, a combination display portion 48 or 58 of a water-droplet pattern may be displayed on each of the rotating wave portion 40 and the main body portion 50. When the combination display portions 48 and 58 are matched with each other Lt; / RTI >

The rotation wave part 40 may include a grinder shaft 42 and a rib 44 for supporting the grinder shaft 42. A spring 46 is inserted into the outer surface of the grinder shaft 42. [

Also, although not specifically shown, a scale may be displayed on the rotating wave 40 to indicate the amount of coffee bean to be ground.

A grinding rotary blade 54 composed of ceramics fixed to a coupling member 52 engaged with the grinder shaft 42 and a grinding wheel 54 composed of ceramics located inside the rotary blade 54, The fixed blade 56 is fixed and a screw groove 62 corresponding to the screw groove 12 of the tumbler 10 can be formed in the lower portion.

A screw member 49 is screwed to the lower end of the grinder shaft 42 to prevent the rotating wave member 40 from being separated.

The grinder 60 does not have a separate handle, grasps the main body 50 with one hand, rotates the rotating wave 40 with the other hand, and grinds the coffee beans stored therein . The principle of grinding the coffee bean is that the grinding rotary blade 54 coupled to the grinder shaft 42 rotates as the rotary finger 40 rotates in the same manner as the conventional ceramic grinder, ) And the grinding rotary blade 54 are grinded and shredded, and this is the same as general grinding, and thus a detailed description thereof will be omitted.

In the embodiment of the present invention, as shown in Fig. 9, the grinding rotary blade 54 and the fixed blade 56 are formed into conical and cylindrical shapes, respectively, The slopes of the threads formed on the outer surface and the inner surface are simply inclined. In contrast, the slopes of the inclined surfaces are bent at a predetermined height from the upper portion to the lower portion to form two inclined portions, Directional inclination, or vice versa. Accordingly, it is suitable for grasping the coffee bean by grabbing the main body part 50 with one hand and by grabbing the rotating wave part 40 with the other hand and by shifting them in the clockwise / counterclockwise direction, A relatively coarse coffee bean is crushed and a relatively thin coffee bean can be crushed by counterclockwise inclination of the bottom.

3 and 7, a lid 70 having a rubber packing 4 interposed thereon is coupled to the upper part of the grinder 60, more precisely to the upper part of the rotating wave part 40, The upper part can be opened and closed. At this time, a gripping groove 64 may be provided on the upper portion of the rotating wave 40 so that the lid 70 can be easily opened. The holding groove 64 preferably has a shape that can be opened by lightly pushing the lid 70 with a thumb.

The lid 70 is formed with a storage space 72 for accommodating a plurality of coffee filters 20 and is provided around the lower portion of the storage space 72 to prevent the coffee filter 20 from being taken out. The inlet can be formed smaller than the width of the accommodating space 72 by forming the protruding portion 74 projecting toward the inside.

The coffee filter 20 shown in Fig. 7 is for a 2-4 person, preferably a filter made of paper, and has a fan shape in which one sheet is overlapped at one side and the lower surface to form a slightly thick joint 22, A plurality of coffee filters 20 can be accommodated in the storage space 72 in the present embodiment.

When the coffee filter 20 of this paper type is used to extract coffee, the lid 70 is opened and the coffee filter 20 accommodated in the receiving space 72 is taken out. Then, When the lower joint 22 and the lower joint 22 are folded alternately and then horizontally folded halfway and then the middle is opened, as the depth is deep and the width is narrowed, , And the coffee filter 20 thus folded is inserted into the filter insertion portion 32 of the dripper 30.

In this state, a configuration in which the grinder 60, the dripper 30, and the tumbler 10 are combined and separated will be described as follows.

When the grinder 60 and the tumbler 10 are coupled to each other, the coffee filter 20 is inserted into the filter insertion portion 32 of the dripper 30 and put in the grinder 60, The gap between the main body portion 50 of the coffee maker 60 is very narrow and the coffee filter 20 is tightly fitted therebetween.

In this state, when the grinder 60 is screwed to the tumbler 10, the flange portion 34 of the dripper 30 is engaged with the engaging jaw 14 of the tumbler 10, So that the inner wall of the tumbler 10 is sealed.

The rubber packing 2 inserted in the ring groove 36 in the circumferential direction seals the inner wall of the tumbler 10 in the flange portion 34 of the dripper 30 so that the coffee filter 20 Since the sealing force of the rubber packing 2 sealing the inner wall of the tumbler 10 is stronger than the bonding force between the dripper 30 and the grinder 60 interposed between the coffee filter 20 and the grinder 60, The dripper 30 can remain engaged with the tumbler 10 even if the threaded connection between the grinder 60 and the tumbler 10 is separated. Thus, coffee is dripped into the tumbler 10 by pouring hot water into the coffee filter 20.

The operation of the portable drip coffee maker according to one embodiment of the present invention will now be described.

First, the lid 70 is opened and one coffee filter 20 folded in the storage space 72 is taken out. Then, the joint part 22 of the bottom part and the side part are staggered, and then folded into a funnel shape, ).

Next, after the main body 50 of the grinder 60 is screwed to the tumbler 10, the rotating beeper 40 and the main body 50 are rotated to grind the coffee beans stored therein. In this case, since the scale (not shown) formed on the rotary hook 40 indicates the amount to be worn for one time, the amount of the wax to be worn is changed, and then the screw connection between the main body 50 and the tumbler 10 The dripper 30 and the tumbler 10 are tightly coupled to each other so that only the main body 50 of the grinder 60 is separated and ready to be dewatered, that is, ready for dripping.

Then, drip coffee is extracted into the tumbler 10 as hot water is poured into the coffee powder contained in the coffee filter 20. At this time, as the steam and heat escape through the plurality of ventilation holes (38) formed in the flange portion (34) of the dripper (30), the taste and aroma of the coffee are softened. The hot water is poured until the extracted coffee is filled in the recognition mark 16 of the tumbler 10.

Finally, after removing the dripper 30 from the tumbler 10, the extracted coffee can be drunk in the tumbler 10.

As described above, the portable drip coffee maker according to the embodiment of the present invention can easily carry the coffee drip coffee maker with a small volume and carry it, hold the predetermined coffee bean without any additional handle, grab the body, You can drink it.

The above description is only one preferred embodiment of the portable drip coffee maker according to the present invention. The present invention is not limited to the above-mentioned embodiment, and therefore, It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
