Hereinafter, the operation and effect of the apparatus having the coffee extracting function of the present invention will be described.

First, the present invention can uniformly squeeze coffee particles with a strong pressure, collect powdered coffee particles with ease and collect them, and keep the temperature of the coffee beans hot so that the coffee does not cool.

For this purpose, FIG. 1, applied to the present invention, shows an overall configuration of an improved device for extracting coffee, wherein the coffee of the coffee feeder 110 is crushed in the coffee crusher 120 and then passed through the crushed coffee inlet 130 to the cylinder 150 And that it has been introduced.

The coffee introduced into the cylinder 150 extracts the espresso coffee having the perfect taste by the coffee pressure extracting means.

2 is a block diagram of a relative part of the coffee pressure extracting means 200 according to the present invention that is lowered through the upper and lower feed screw 140. FIG. FIG. 4 is a cross-sectional view of a coupled state of the coffee pressure extracting means 200 applied to the present invention. When coffee powder is introduced into the cylinder 1150, the coffee pressure extracting means 200 descends as shown in FIG. .

More specifically, when water flows through the water supply valve 260, the water flows through the water supply tube 211 to the water injection device 230 through the body of the extraction piston 210. The water introduced into the water injector 230 descends through the hole 231, is dispersed in the space 235 in four directions, and is discharged through the extraction piston filter 240.

The space portion 235 is formed by a plurality of protrusions 232 protruding from the lower end of the water injection device 230 to form a space between the water injection device 230 and the extraction piston filter 240, So that a strong water stream is prevented by the extraction piston filter 240 and spreads to the side so as to be dispersed over a wide area so that the pressure of water can be uniformly applied to the entire inner circumference of the cylinder 150 .

When the pressure spring 250 generates a pressure of 9 to 15 atmospheres in the cylinder 150, the coffee pressure extracting means 200 applies a pressure spring 250 for protecting the machine when the espresso coffee is squeezed with a strong force The extraction piston 210 is lifted up by the interval and when the strong pressure is received, the extraction piston 210 is lowered by the elastic force of the pressure spring 250 to squeeze the remaining water in the coffee particles.

FIG. 5 is an exploded perspective view of the coffee beverage collecting means 300 applied to the present invention, and FIG. 6 is a sectional view of the coffee bean spout collecting means 300 applied to the present invention in an engaged state. ) To take out the coffee juice squeezed at a pressure of 9 to 15 atmospheres and send it out through the coffee discharge valve 340 and the transfer tube 350 again.

That is, according to the present invention, the coffee filter 33 prevents the particles of the ground coffee from entering and allows only the groundwater to flow into the space 311 inside the coffee collection and transportation unit 310. The filter housing 320 functions as a support for holding the coffee filter 330 in a non-pushed state and maintaining a predetermined space, and serves to send the extracted liquid to the space 311 through the hole 321. The coffee that has flowed into the space portion 311 is discharged through the coffee extracting port 312 and flows into the coffee temperature maintaining and discharging means 400 through the coffee discharge valve 340 and the transfer tube 350.

The coffee having passed through the coffee ground liquid collecting means 300 flows into the coffee temperature maintaining and discharging means 400 as described above.

7 is an exploded perspective view of the coffee temperature holding and discharging means 400 applied to the present invention, and Fig. 8 is a sectional view of the coupled state of the coffee temperature holding and discharging means 400 applied to the present invention. It is discharged into the coffee cup while being kept warm.

More specifically, the coffee liquid flowing into the extraction port body 410 through the transfer tube inlet 412 is maintained at a temperature of about 70 to 80 degrees Celsius by the heater 420.

Since the heater 420 can be opened when the temperature of the extraction port body 410 is not hot during the flow of the coffee bean liquid, the temperature of the extraction port body 410 is kept hot to maintain the coffee not to cool And also serves to keep the extraction port 440 hot through heat conduction.

The coffee that has been heated in the extraction port body 410 is discharged to the extraction port 440 through the discharge port 414 and the coffee is discharged to the both coffee ports through the extraction port 440.

The present invention also keeps the extraction port 440 hot by heat conduction so that it does not cool until the final coffee is drained.

The cover 430 applied to the present invention prevents foreign matter from entering into the extraction port body 410 and prevents the coffee from flowing into the heater.

The technical idea of the apparatus improved in the coffee extracting function of the present invention is that the same result can be repeatedly practically practiced. Especially, by implementing the present invention as described above, it is possible to contribute to industrial development by promoting technological development.
