In order to
The lever 32 is at pressure 1. It rotates upward against the spring force of the m coil spring 34 to open the liquid passage hole 23. After performing the above operations, when the motor 11 is energized, the cutter 16 rotates and grinds the coffee beans in the case 14 into coffee powder. Then, when the sheathed heater 5 is energized, hot water is supplied from the hot water supply pipe 8 to the lifted ore scatterer 58, and further this hot water drips into the case 14 from the pouring hole 69 of the lifted ore scatterer 38. The dropped hot water penetrates into the coffee powder and extracts the coffee extract to become coffee liquid, and then passes through the filter 15.
It is filtered and dripped into the receiver 19, and after passing through the auxiliary filter 37, it flows out from the liquid passage hole 23 and becomes photo lv9.
stored within. When extracting this coffee liquid, filter 1
If the water level in the case 14 rises abnormally due to someone looking at the person 5, the hot water in the case 14 overflows into the passage 14a and flows from the passage 14 into the outlet 22, causing the field to become cold. There is no chance of spilling onto the table where Body 1 is placed.

After extracting the coffee liquid in this way, when the bottle 9 is removed from the handle 8 part 3, the lever 52 of the valve 31 is rotated downward by the spring force of the compression coil spring 54, allowing the liquid to pass through. Hole 23 is closed. For this reason, the coffee liquid remaining in the receiver 19 after removing the photo/L/9 is removed from the liquid passage hole 23.
There will be no inconvenience such as dripping from the bottle and staining the bottle and the cap 1 part 5.

Now, after extracting the coffee liquid, the case 14 and the receiver 19
When cleaning the inside, open the lid 40 and open the hot water pipe 8.
Turn and remove from the top of the case 14. After that, the upper end of the case 14 is individually rotated counterclockwise in multiple directions. At this time, since the receiver 19 is prevented from rotating with respect to the case 14 by the locking member 23 as described above, the receiver 19 rotates in the counterclockwise nine directions integrally with the case 14. Then, when the case 14 is rotated by a predetermined angle and the convex portion 26 of the receiver 19 comes into contact with the guide groove 13a, the case 14 is lifted upward, and the receiver 19 is moved together with the case 14 to the case attachment part of the container body 1. Out of 11. After removing the case 14 and the receiver 19 from the container body 1 in this way, when the operating portion 30 of the locking member 28 is pressed as shown in FIG.
The case 14 is rotated downward against the spring force 4 to release the engagement between the engagement protrusion 29 and the engagement recess 27, and in this state, the case 14 is rotated counterclockwise with respect to the receiver 19. Move the protrusion 21
The case 14 is disengaged from the bayonet engagement groove 18, and the case 14 is removed from the receiver 19. After this, the case 14 and the receiver 19 are washed separately.
