Reference numeral 7 denotes a mill portion having a substantially cylindrical shape. The mill portion 7 puts coffee beans therein and makes it into coffee powder by a cutter driven by a motor. Reference numeral 8 denotes a basket which is provided alongside the mill unit 7 and communicates with the mill unit 7 through a metal filter having a large number of holes each having a diameter of about 2 mm. When the coffee beans ground in the mill section 7 are crushed by the cutter and become smaller than the diameter of the hole of the filter, the coffee beans are ejected from the hole of the filter into the basket 8 by the centrifugal force of the cutter. Reference numeral 9 denotes a basket lid which is placed so as to cover the mill portion 7 and the basket 8. A cylindrical rib 10 is provided on the basket 8 side of the basket lid body 9 and a part thereof serves as a notch portion 11. ing. The cylindrical rib 10 has seven drip holes 12 along its inner wall. A discharge port 13 is rotatably provided on the upper portion of the main body 1. When the discharge port 13 is turned counterclockwise when viewed from above,
As shown by the broken line in FIG. 2, it abuts against the protective rib 14 provided on the upper portion of the main body 1. On the contrary, when it is turned clockwise, it comes into contact with the notch 11 of the cylindrical rib 10 of the basket lid 9.
Reference numeral 15 is a contact rib provided on the discharge port 13. 16 is provided on the main body lid 2 and has a large rounded portion 1 on one side.

When the main body cover 2 is closed by rotating the discharge port 13 to the position shown by the solid line in FIG. 2, the discharge port 13 is closed as shown in FIG.
The rounded portion 17 comes into contact with the contact rib 15 of FIG.

Reference numeral 18 is a tank for storing water, and 19 is a glass container for storing the extracted coffee liquid. Reference numeral 20 is a handle of the glass container 19. Reference numeral 21 is a timer switch, which controls the time of the cutter driving motor of the mill unit 7. 22
Is a start button. Reference numeral 23 is a water rising pipe that communicates with the discharge port 13 and through which hot water passes, and 24 is the discharge port 1
3 is a communication bushing that allows it to rotate and maintains water tightness with the water rising pipe 23, and is made of silicon rubber or the like.

Although not shown in the drawing, in FIG. 1, a heater whose temperature is controlled by a thermostat or the like is built in the main body 1 located below the glass container 19 to heat water into hot water.

In the electric coffee brewer configured as described above,
Next, the operation will be described. First, water is put in the tank 18, coffee beans are put in the mill part 7, and a paper filter is set in the basket 8. Then, the basket lid 9 is placed on the basket 8. At this time, the discharge port 13 is in contact with the protection rib 14.

Next, the discharge port 13 is manually rotated to the cutout portion 11 of the cylindrical rib 10. Then, the main body lid 2 is closed, and the claw 5 of the lock knob 4 is engaged with the locking portion 6 and locked. At this time, the discharge port 13 is sandwiched between the cutout portion 11 and the rounded portion 17 of the positioning rib 16 and faces a certain direction. The direction in which the discharge port 13 faces is the tangential direction of the inner wall of the cylindrical rib 10, as shown in FIG.

In such a state, when the timer switch 21 is set to a predetermined position and the start button 22 is pressed, the coffee beans stored in the mill unit 7 are crushed by a cutter driven by a motor, and further centrifugal force is generated by the rotation of the cutter. It jumps out from the hole of the filter and is stored in the paper filter set in the basket 8. Eventually, when the timer stops the motor and the heater is energized, the water in the tank 18 is heated, and the water vapor pressure spurts out from the discharge port 13 vigorously. At this time, the discharge port 1
Since 3 is oriented in the tangential direction of the inner wall of the cylindrical rib 10 as described above, the hot water jetted vigorously is
While falling in a circular motion along the inner wall of No. 0, it falls into the basket 8 through the plurality of drip holes 12. in this case,
The hot water jetted out vigorously due to the water vapor pressure, so that it makes almost one turn when making a circular motion along the inner wall of the cylindrical rib 10, so the amount of hot water dropped into the basket 8 from each drip hole 12 becomes uniform. Will be done.

In this way, the hot water is evenly dropped into the basket 8 so that the coffee can be extracted efficiently, and since a large amount of hot water does not pass through a portion of the coffee in a concentrated manner, no excess components are extracted and a delicious coffee is produced in a glass. It will be dropped and stored in the container 19.

Since the heater is temperature controlled, when the drip is completed, the glass container 19 is heated from the bottom to keep the coffee warm.

Further, in the initial preparation stage, even if the operator forgets to manually rotate the discharge port 13 to the cutout portion 11, by closing the main body lid 2, the rounded portion 17 of the positioning rib 16 causes the contact rib 15 of the discharge port 13 to come into contact. Since pressing is rotated to a predetermined position, coffee extraction can be performed without failure.
