It is set as a.

The body 5 located below the hot water supply hole 39 of the water spray container 36 has an inlet 2 of the diffusion gutter 23.
4 is formed, and a recess B for storing hot water is formed in this step A so as to face the hot water supply hole 39.

To explain the operation with such a configuration, upper case 8
The process is started by storing the desired coffee beans in the container b and the desired water in the water tank 2, and then rotating the knob 12a of the timer motor 12 and pressing the power switch 25. First, the drive motor 6 is driven to rotate the cutter 19 to crush the coffee beans and collect them as coffee powder in the filter 17 through the through holes 14a of the sieve plate 14. During the rotation of the cutter 19, the outflow hole 46 of the rotor 45 is transferred to the first partition 37 by the transmission from the rotating belt 28 to the horizontal rotating rod 31 to the rotor shaft 33 to the rotor 45.
It is rotating in the direction of the arrow so that it is located at point a. Then, after a predetermined period of time has elapsed, the drive motor 6 stops rotating, and then the heater 9 is switched and energized to heat the water in the hot water supply pipe 11 in a drip method.
At this time, the water remaining in the hot water supply pipe 11 with a small inner diameter from the heater 9 to the rotor 45 becomes lukewarm water and is supplied to the rotor 45, and the outflow hole 46→first partition 37a→return hole 37→ It is returned via a route to water tank 2. Subsequently, after a predetermined period of time has elapsed, the rotor 45 is further rotated in the direction of the arrow by the hot water pipe 11, and the outflow hole 46 is moved to the third section 39a.
Directly facing the rotor 45 → outflow hole 4
6 → Third compartment 39a → Hot water supply hole 39 → Diffusion gutter 23
The hot water is supplied to the coffee powder in the filter 17 below the diffusion gutter 23 to promote swelling. When hot water suitable for swelling is supplied to the coffee powder, the rotor 45 is further rotated to make the outflow hole 46 face the second partition 38a, and during swelling, the hot water is returned to the water tank 2 side. When the time for the end of the swelling has further elapsed, the outflow hole 46 of the rotor 45 stops at the third partition 39a and operates to continuously supply hot water to the diffusion gutter 23 side.
When hot water is supplied to the swollen coffee powder, a coffee liquid with good flavor is obtained.

In addition, since the display body 47 fixed to the rotor 45 is also rotating during hot water supply, the user can confirm through the transparent cover that hot water is being supplied. Since it is small, the supply speed of hot water is faster.

Even if the mill case 8 is removed as shown in FIG. 8 after extracting the coffee liquid, the residual hot water flowing down from the hot water pipe 11 through the hot water hole 39 will not flow into the recess B.
It is possible to prevent the water from being accumulated in the air, flowing down onto the surface of the machine body 5 and staining it, or from getting the drive motor 6 wet through the insertion portion of the transmission shaft 21 and causing rust.

In the embodiment of the present invention, the hot water supply hole 39 is located in the recess B.
Although it is formed so as to face the hot water supply pipe 1
1 may be extended, and the tip opening of the hot water supply pipe 11 itself may be configured to face the recess B.

(f) Effects of the invention Since the invention is constructed as described above,
When the mill case is removed from the main unit after brewing coffee, the residual hot water that drips from the hot water pipe through the hot water supply hole can be collected in the recess, eliminating the problem of staining the main unit or getting the drive motor wet, unlike conventional methods. It can be resolved.
