Next, the effect will be explained.

First, the hopper lid 18 is opened and a desired amount of coffee beans is put into the hopper 5. Then, some of the coffee beans enter the grinding chamber 16 through the bean inlet 13. Next, basket 2
1, the filter 23 is set on the basket M241 equipped with the basket packing 26, and when the basket M241 is inserted under the eaves part 4 of the main body 1, the basket packing 26
The semicircular portion 26a is the arcuate recess 11 at the lower end of the guide tube 11.
a VC sliding engagement is performed and n-μ is performed. At this time, since the semicircular part 26a of the basket packing 26 contacts the four arcuate parts 11a from the outside and the basket packing 26 is configured in a semicircular shape, even if the positions of the basket packing 26 are slightly deviated from each other, the sea/V will be carried out reliably. Next, the hopper lid 18 is closed, locked with the lock knob 20, and water is poured into the water tank. Next, by operating a timer (not shown) and applying 11!1 power to the motor 6, the grinding body 8 rotates and the coffee beans in the grinding chamber 16 are ground. The crushed coffee powder is passed through the outlet 9 and the guide tube 11.
The liquid passes through the filter 21 and falls onto the filter 23 of the filter 21. At this time, the lower end of the cover body 12 is locked around the air outlet 9, and the upper end is connected to the stopper 14 in the locking part 14.
5, so it will not come off due to the impact during crushing.

Further, since the guide tube 11 and the basket lid 24 are sealed by the basket gasket 26, coffee powder does not blow out to the outside. When the coffee beans inside the hopper 5 run out, the timer stops the siphon motor 6, and the hot water Yt28 and hot water nozzle 1v1 of the hot water supply device 27
Hot water is discharged upward from 7. In addition, since the tip outlet of the hot water supply nozzle 1v17 is opened at a position that is flatter than the bean inlet 13 of the cover body 12, the coffee powder that flies during grinding does not enter the inside of the hot water supply nozzle 17, and no clogging occurs. . The hot water discharged from the hot water supply nozzle 17 washes away the coffee powder adhering to the inner surface of the hopper lid 186') and the inner surface of the hopper 5, and then enters the inside of the grinding chamber 16, where it also cuts into the inside of the grinding chamber 16. 21) Pour out the ground coffee along with it, and pass it through the guide cylinder 11.
The internal VC drips. At this time, the inside of the crushing chamber 16 is cleaned by driving the motor 6 again to rotate the crushing body 8. Motor 6 for a few seconds
When the re-driving is finished, all the coffee powder is removed from Basquera)2
1, and when hot water is further supplied, it passes through the guide tube 11 to the cylindrical portion 26b of the basket gasket 26, and this cylindrical portion 26b protrudes toward the basket gasket 21. Therefore, the predetermined optimal extraction position V
C Hot water is dripped to efficiently extract delicious coffee liquid, which is stored in a heat-resistant container 31. In addition, for cleaning, the hopper 5, the cover body 12, the crushing body 8, the air outlet 9, and the guide tube 1 are used.
1 has been mostly washed, and only the basket 21, basket lid 24, and heat-resistant container 31 need to be washed, which saves time and effort.

Effects of the Invention As is clear from the description of the embodiments above, according to the VC present invention, the hot water supply nozzle is provided facing upward, and its tip outlet is located above the bean inlet of the cover body of the crushing body. Therefore, even if VC coffee powder is scattered during grinding, it does not enter the tip outlet of the hot water supply nozzle.As a result, the structure and structure are simplified and do not require an intrusion prevention device such as a diffuser as in the past. In addition, there is no need to worry about damage to the diffuser.
