In the electric coffee brewer configured as described above,
Next, the operation will be described. First, the lock button 19
Remove and open the main unit lid 17. Then, the discharge port 9 is rotated to the angle of the broken line in FIG. Then, the basket lid 6 is removed and the coffee beans are put in the mill section 3. Drip section 4
Set a paper filter to. Then, the basket lid 6 is placed on the basket 5. Then, the discharge port 9 is manually rotated to the position shown by the solid line in FIG. Next, by pulling the upper part of the water tank 2 to the left of the main body 1, the upper end surface 14 of the water tank 2 is released from the contact with the pressing claw 13, and the water tank 2 can be pulled out obliquely upward to the left.
At this time, the outflow port 26 is pulled out obliquely upward to the left from the receiving port 32 to release the watertightness of the O-ring 31. Then, when a predetermined amount of water is put into the water tank 2, the valve 28 is hydraulically operated and its slope portion
The water is not leaked even when the water tank 2 is carried, because 29 is pressed against the brim portion 27 and becomes watertight. The water tank 2 is set in the main body 1 from the left side of the main body 1. First, with the water tank 2 slightly tilted to the left, the outflow port 26 is guided and inserted into the receiving port 32, and then the recess 23 at the upper part of the water tank 2 is inserted.
The contact end surfaces 24a and 24b of the water tank 2 are guided to contact the outer walls 25a and 25b of the circulation port 12, and at the same time, the upper end surface 14 is contacted and slid on the lower surface of the pressing claw 13 to push the water tank 2 from the left side to the vertical direction. ,
When the outer surface of the water tank 2 contacts the outer surface of the main body 1, the water tank 2
Is complete. At this time, the O-ring 31 provided at the outflow port 26 maintains the watertightness with the receiving port 32, and at the same time, the elastic force of the rubber material thereof causes a force to push the entire water tank 2 upward. . Then, the water tank 2 is pressed against the pressing claw 13 by the upward force of the O-ring 31, and further abuts the outer walls 25a, 25b of the circulation port 12 and the abutting end faces 24a, 24b to the rear side of the main body 1. It will be set in the main body 1 without falling down or to the left. Now that the preparation for coffee extraction is complete, the main body lid 17 is closed and the lock button 19 is set. At this time, the fall prevention rib 21 integrally extended below the main body lid 17 enters the inside of the water tank 2 and makes one end face abut against the inner surface 22 thereof. As a result, even if the water tank 2 tries to fall to the left side, it does not fall because the inner surface 22 is pressed by the fall prevention rib 21. Therefore, by closing the main body lid 17, the water tank 2 does not fall off the main body 1 and fall down.

Next, when a predetermined time is set by the knob 35 of the timer and the start button 36 is pressed, the cutter in the mill unit 3 is rotationally driven by the motor to crush the coffee beans and at the same time a centrifugal force is generated by the rotational force of the cutter. Then, the ground coffee particles pass through the holes of the filter and are stored in the paper filter of the drip section 4. Then, when the driving of the motor is stopped by the timer, the water in the water tank 2 is heated by the heating body (not shown) this time and jetted from the discharge port 9. Then, this hot water is jetted out to the inside of the cylindrical rib 8 of the basket lid 6 to be drip portion 4 through the drip hole 7.
Extract the coffee by dripping on the paper filter stored in. The extracted coffee is dropped and stored in the glass container 34.

When the main body lid 17 is opened to discard the coffee grounds in the drip portion 4 or to wash it with water after the extraction is completed, at the same time, the fall prevention ribs 21 formed integrally with the main body lid 17 are also attached to the inner surface 22 of the water tank 2. Since it is separated from the water tank 2, the water tank 2 can be removed.

As described above, in one embodiment of the present invention, the function of the fall prevention rib 21 for preventing the fall of the water tank 2 can be released at the same time by one operation such as opening the main body lid 17, and the water tank 2 can be immediately removed. it can. On the other hand, in one operation such as closing the main body lid 17, at the same time, the function of the overturning prevention rib 21 for preventing the overturning of the water tank 2 can be activated to prevent the water tank 2 from falling over.

Further, the water tank 2 is temporarily fixed by pressing it against the pressing claw 13 using the elastic force of the O-ring 31, and then the main body lid 17 is closed to prevent the water tank 2 from tipping over. The operation of hooking at the time of setting is also unnecessary, and as a result, the water tank 2 can be attached and detached by a simple operation.

Further, the force pushing the water tank 2 from the bottom is the elastic force of the O-ring 31 originally generated to obtain watertightness, and the fall of the water tank 2 is extended from the main body 1 and the main body lid 17. Since the pressing claws 13 and the fall prevention ribs 21 are used, no special parts for fixing the water tank 2 are required.

Effects of the Invention According to the present invention, as is clear from the description of the above embodiments,
