1 and 3, the drier housing 300 is detachably coupled to a lower portion of the water supply unit 100. [

An opening is formed in the upper part of the drier housing 300 and an engaging groove 310 is formed in the lower part to support the drier 320 so that the drier 320 can be detachably mounted.

As shown in FIG. 3, in the temporal example of the present invention, a plurality of insertion grooves are formed on the inner circumferential surface of the lower end of the water supply part 100, and a plurality of coupling protrusions The shape of the insertion groove of the water supply part 110 and the shape of the coupling protrusion provided on the drier housing 300 may be different from each other. And the coupling between the water supply unit 100 and the driper housing 300 may be modified into various forms such as a screw coupling type.

2A, the drier 320 is fixed to the drier housing 300 by being detachably inserted into the coupling groove 310 formed at the lower portion of the drier housing 300. As shown in FIG.

The droplet 320 serves to receive the coffee bean powder. The droplet 320 has a cylindrical shape with an open upper part, and has a smaller diameter toward the lower part. The lower part of the droplet 320 has an extraction port 321 for discharging the extracted coffee, .

Although three extraction ports 321 are formed in FIG. 2A, the number of the extraction ports 321 is not limited to three, but may be two or four or more depending on the capacity of the drier 320.

As shown in FIG. 2A, a filter 330 is detachably coupled to a lower inner surface of the droplet 320.

The filter 330 is a mesh structure for filtering the coffee powder and extracting the coffee bean liquid from the coffee bean powder. The filter 330 has a size corresponding to the lower surface of the drier 320.

When the water in the water supply unit 100 is supplied to the drier 320 in the drier housing 300 when the discharge port 110 of the water supply unit 100 is opened, And then discharged to the coffee storage unit 400 through the extraction groove 321.

The filter 330 may have a mounting groove 331 for fixing the screw 340 to be described later.

The screw 340 is vertically coupled to the mounting groove 331 of the filter 330 to be detachable.

It is preferable that the mounting groove 331 of the filter 330 is formed at a position corresponding to the extraction groove 321 formed in the drier 320.

The screw 340 is fixed to the drier 220 by being fitted into the mounting groove 331 formed in the filter 330.

Since the screw 340 is formed in a radial shape, an effect that the varista can hold the kettle and circulate the droplet and uniformly supply the water can be obtained.

Since the screw 340 extends in a spiral form extending in the radial direction and extends downward in the form of a spiral from the outer diameter side of the droplet 320 toward the center portion, the water supplied from the water storage portion 100 flows into the droplet 320, And moves along the trajectory of the spiral shape.

When the water in the water supply unit 100 is supplied to the drier 320, a portion of the coffee ground liquid is spirally rotated through the screw 340 while passing through the filter 330, And then discharged to the coffee storage unit 400.

As shown in FIG. 3, a coffee storage unit 400 having an opening at an upper portion thereof is detachably coupled to a lower portion of the drifter housing 300.

The coffee storage part 400 serves to receive the coffee extracted from the extraction port 321 of the drier 320 and serves as a cup for drinking coffee.

The coffee storage part 400 may be formed of a stainless steel material to prevent discoloration due to coffee and facilitate washing.

3, a plurality of insertion grooves are formed in the inner circumferential surface of the lower end portion of the droplet housing 300 in the temporary example of the present invention. On the outer circumferential surface of the upper end portion of the coffee storage portion 400, The shape of the insertion groove of the drier housing 300 and the shape of the insertion hole of the coffee storage part 400 may be different from each other. The shape of the coupling protrusion may be modified in various forms, and the combination of the driper housing 300 and the coffee storage part 400 may be modified into various shapes such as a screw coupling type.

As shown in FIG. 3, a coffee storage compartment 500 having an opening at its upper portion is detachably coupled to a lower portion of the coffee storage 400.

The barriers 510 may be formed integrally with the bean storage 500 so as to define a space from the opened top to the bottom. The barriers of the bean storage 500 may store various types of coffee for storage.

As shown in FIG. 3, in the instant embodiment of the present invention, a plurality of insert-coupling grooves are formed on the inner circumferential surface of the lower end of the coffee storage part 400, and a plurality of The engaging protrusions are formed to engage the engaging protrusions of the bean storage 500 with the engaging recesses of the coffee storage 400. However, the shape of the inserting recess of the coffee storage 400 and the shape of the bean storage 500 may be modified in various forms, and the combination of the coffee storage part 400 and the bean storage part 500 may be modified into various forms such as a screw coupling type.

The portable coffee maker having the water supply unit 100, the drier housing 300, the coffee storage unit 400, and the bean storage 500 may be formed in a cylindrical shape, but the present invention is not limited thereto.

The process for producing coffee beans in the portable coffee machine according to the above-described construction is as follows.

The combined water supply unit 100, the driper housing 300 equipped with the drier 320, and the bean storage 500 are separated and opened.

After the filter 330 is inserted into the drier 320 and the screw 340 is mounted on the mounting groove 331 of the filter 330, an appropriate amount of the ground coffee powder accommodated in the bean storage 500 is introduced into the drier housing The upper portion of the droplet housing 300 is engaged with the lower side of the water supply unit 100. The upper portion of the droplet housing 300 is coupled with the lower portion of the water supply unit 100,

Then, the water supply unit 100 is filled with an appropriate amount of hot water. The user presses the button 210 to open and close the discharge port 100 to supply water to the drier 320. That is, when the button 210 is pressed, the opening / closing plate 120 is drawn in, and the discharge port 110 of the water supply unit 100 is opened because the discharge port 110 and the opening and closing unit 121 are aligned The water in the water supply unit 110 is supplied to the drier 320 in the drier housing 300 through the discharge port 110.

When the water is supplied into the drier 320, the coffee raw solution is discharged through the filter 330 to the coffee storage part 400 through the droplet extracting groove 321 for a predetermined time, And is extracted through the extraction groove 321. [0064]

If an appropriate amount of coffee is contained in the coffee storage part 400, the button 210 is pressed again to close the discharge port 110 to stop the water supply through the water supply part 100. That is, when the button 210 is pressed again, the opening / closing plate 120 is drawn out and the discharge port 110 and the opening / closing plate 121 are displaced, so that the discharge port 110 of the water supply unit 100 is closed, 320).

After opening the coffee storage unit 400 coupled with the drifter housing 300, coffee can be drunk using the coffee storage unit 400.

As described above, the present invention can be easily carried by miniaturizing the volume, so that the coffee bean can be easily manufactured and consumed at any place.

The embodiments and drawings of the present invention should not be construed as limiting the scope of the present invention, but can be modified and embodied in various embodiments.
