Next, the operation of this embodiment having the above configuration will be explained.

First, a case will be described in which a coffee liquid of a normal concentration is obtained using a fixed amount (e.g., 8 cups). Fill the water storage tank 8 with water for 8 children (for 8 people), store the corresponding amount of coffee beans in the case 14, and press the standard push button 40.
When the standard setting signal S40 is generated by suppressing the standard setting signal S40, the mill time counter 51 to which this standard setting signal S4 is given will set the memory time (for example, 13 seconds).
click (operation command signal 551 is activated at the same time as operation is started)
a is generated and applied to the motor relay drive circuit 56, and the motor relay drive circuit 53 becomes energized to the excitation coil l'V47eL of the motor relay 47, so that the motor relay 47 is normally The open contact 47'b is turned on to energize the motor 19 of the mill mechanism 2, so that the motor 19 rotates the ivy 17 to crush (mitv) the coffee beans in the case 14. is started.

The drip pattern storage circuit 54 to which the standard setting signal 840 is applied selects the regular drip pattern shown in FIG. 5
6 is configured to energize the excitation coil/I/49a of the capacity switching relay 49 to turn on its normally open contact 49b,
Therefore, the diode 50 connected in series with the sheathed heater 10 is short-circuited by the normally open contact 49b. Thereafter, when the mill time counter 51 finishes counting the memory time (for example, 13 seconds), the mill time counter 51 generates a stop command signal 5s1b and sends it to the motor relay drive circuit 53. Therefore, the motor relay drive circuit 5
3 turns off the excitation coil (l/471) and returns the motor relay 47, thus completing the milling process. Further, the stop command signal 5 of the mill time counter 51
Since the signal s1b is given to the drip pattern storage circuit 54, the drip pattern storage circuit 54 starts the hot water supply (drip) process based on the regular drip pattern shown in FIG. 5(a) selected as described above. That is, in the drip process according to this regular drip pattern, the ON command signal 5s4a is continuously generated and applied to the heater relay drive circuit 55, and the heater relay m drive circuit 55 is continuously generated by the excitation coil/ energize l/48a to activate the heater relay 48 and close its normally open contact 4.
Turn on B'b continuously. As a result, the sheathed heater 1o is energized and generates heat with a large capacity of 800 watts.

Then, when the sheathed heater 10 generates heat, the heating plate 9 is heated, thereby preheating the photo/I/4 placed on the bottle placement section 6 and simultaneously supplying water from the water storage tank 8 through the water supply pipe 12. The water in the heating pipe 11 is heated to generate hot water. The hot water generated as described above rises in the hot water supply pipe 13 due to its boiling pressure, is supplied from the hot water supply port 13a to the inside of the wall 25a of the lid 25, and is supplied to the case 14 from the hot water pouring hole 25b. Supplied drip-wise inside. Furthermore, the hot water supplied into the case 14 passes through the coffee powder and the filter 21 and is extracted as coffee liquid, and this extracted coffee liquid flows out from the extraction port 24 of the case 14 and flows into the bottle/L/4. It falls and is stored. In this way, when the sheathed heater 10 is continuously energized based on the regular drip pattern and the coffee liquid is extracted by continuously supplying hot water into the case 14, the coffee liquid is With a higher concentration, so-called Reguffe coffee can be obtained. Thereafter, when all the water in the water storage tank 8 is consumed, the drip process ends. That is, when the standard push button 40, which is a predetermined operation button, is operated, the mill time by the MI/I/mechanism 2 is a predetermined time of 15 seconds.

On the other hand, a case will be described in which the mill time, drip pattern, and amount of coffee liquid are selected as desired. First, a desired cup of water is poured into the water storage tank 8, a corresponding amount of coffee beans is stored in the case 14, and the amount of coffee beans corresponding to the amount of water is poured into the water storage tank 8. In the case of ~4 presses, the small capacity push button 37 is suppressed, and in the case of 5 to 8 presses, the large capacity push button 3B is suppressed. Here, by pressing the small capacity push button 37, the small capacity setting signal Ssy is applied to the capacity switching relay drive circuit 56, and the excitation coil 49a of the capacity switching relay 49 is de-energized and its normally open state is applied. It is assumed that the contact 49b is turned off. Furthermore, the regular push button 65 or the strong push button 66 is pressed depending on the desired strength of the coffee liquid. Here, it is assumed that the strong drip pattern shown in FIG. 5(1) is selected by suppressing the strong push button 56 and applying the strong setting signal S36 to the drip pattern storage circuit 54. And mill time counter 5
1, by suppressing the mill time push button 61 to give the mill time setting signal Ss<, and then suppressing the minute push button 54 to give the minute setting signal Ss4, the mill is set for the desired number of seconds. When the time is set and then the start push button 59 is pressed to give the start signal Sip, the mill time counter 51 starts counting the set time and generates the operation command signal 5s1a. Then, a milling process similar to that described above is started. Thereafter, when the mill time counter 51 finishes counting the set time and generates a stop command signal 5511), the mill process ends and this stop command signal 851'b is given to the drip pattern storage circuit 54. A drip process is started. That is, in this drip process, as shown in Fig. 5 (
Controlled based on the strong drip pattern shown in b), the drip pattern storage circuit 54 first generates an ON command signal 5saa to energize the excitation coil 48a of the heater relay 48 via the heater relay drive circuit 55. Turn on the normally open contact 481) to turn on the sheathed heater 1.
0 is energized. In this case, since the sheathed heater 10 is energized through the diode 50 in series, it generates heat with a capacity of 400 feet.

Therefore, hot water is supplied to the case 14 in the same manner as described above. Thereafter, when a certain period of time ta (for example, 1 minute) has elapsed, the drip pattern storage circuit 54 outputs an off command signal 554.
b is generated and the excitation coil lv48a of the heater relay 48 is cut off via the heater relay drive circuit 55 to turn off the normally open contact 48D9, so the sheathed heater 10 is cut off and the case is Stop supplying hot water to the interior of 14. As a result, the hot water supplied into the case 14 by energizing the sheathed heater 10 for a certain period of time permeates the entire area of the coffee powder in the case 14 and moistens the coffee powder food.
Extraction of the coffee extract contained in the coffee liquid is promoted. Thereafter, when a certain period of time tb (for example, 1 minute) has elapsed, the drip pattern storage circuit 54 generates the ON command signal 5s4at- again to turn on the normally open contact 48b of the heater relay 48), and the sheathed heater 10 turns on. Electricity is applied and hot water supply into the case 14 is restarted. After that,
The drip pattern memory circuit 54 continuously generates the ON command signal 5s4a to close the normally open contact 48 of the heater relay 48.
b is turned on, hot water is continuously supplied into the case 14, and coffee liquid is extracted. In this way, if the coffee powder food is once moistened based on the strong drip pattern to promote the extraction of the coffee extract, and then the coffee liquid is extracted by continuously supplying hot water, the coffee liquid will become the same as the above-mentioned regular coffee. You can also get a so-called strong coffee with a high concentration. Thereafter, when all the water in the water storage tank 8 is consumed, the drip process ends. That is, when the start push button 69, which is a predetermined operation button, is operated as described above, the milling time by the milling mechanism 2 becomes the predetermined time selected and set.

Now, a case will be described in which the timer counter 52 is used to start coffee production after a desired time.

In the same manner as described above, set the desired mill time in the mill time counter 51, select the desired drip pattern in the drip pattern storage circuit 54, and select the capacity of the sheathed heater 10 in the capacity switching relay drive circuit 56. do. After that, the timer push button 30 is placed on the timer counter 52.
Set the desired time in minutes by suppressing the hour push button 35, and set the desired time in hours by suppressing the hour push button 35 and supplying the hour setting signal Sss. 62 to give a timer set signal S52. For this purpose, timer counter 5
2 starts the timing operation of the set time, and then when the timing operation of the set time is finished, a start signal S52 is generated and given to the mill time counter 51. Therefore, the milling time counter 51 starts counting the set milling time and generates the operation command signal 5s1a, thereby starting the milling process. after that,
When the mill time counter 51 finishes counting the set mill time, it generates a stop command signal 5s1b, and the mill process ends. Also, since this stop command signal 5s1b is given to the drip pattern storage circuit 54, the drip process is started, and the drip pattern storage circuit 54 controls the flow of the sheathed heater 10 based on the selected regular drip pattern or strong drip pattern. While controlling the power outage, the sheathed heater 10 generates heat at the selected capacity of 800 watts or 400 watts. In this way, the milling process and the dripping process are performed after a desired amount of time has elapsed, and a desired amount of Reguff coffee or strong coffee can be obtained.

Note that when the clock push button 29 is depressed, a clock counter (not shown) is set and the clock is displayed on the display 28. In this case, the minutes and hours cannot be corrected. This is done by pressing the minute push button 34 and the hour push button 53, respectively.

In this way, according to this embodiment, the standard push button 40
When the suppression operation is performed, the sitribing process is performed according to the preset regular drip pattern, and the preset large capacity, for example, 8-pot regular coffee is automatically obtained. Therefore, if you want to get a large amount of regular coffee over your family structure, you can do it with a so-called one-touch operation by simply pressing the standard push button 40. Even when obtaining a large volume of coffee liquid such as 1 minute, the sheathed heater 10 can be used for 1 to 4 times for small volumes.
Since the 00 Watt Yo Shi also generates heat using 800 watts, the drip process does not take a long time.

Further, according to this embodiment, by setting the mill time to a desired value in the mill time counter 51, the grinding particle size of the coffee beans can be selected as desired, and the drip pattern storage circuit 54 allows the drip pattern or In addition to being able to select a strong drip pattern as desired, the desired heat generation capacity of the sheathed heater 10 of 800 watts or 400 watts can be selected using the capacity switching relay drive circuit 56, so that coffee liquid with the desired flavor and strength can be obtained. You can get just the desired amount.

Moreover, according to this embodiment, by setting a desired time on the timer counter 52, coffee production consisting of a milling process and a drip process can be started after the set time has elapsed. By setting the counter 52, it is extremely convenient to obtain the desired taste, desired strength, and desired amount of coffee liquid the next morning.Even in this case, the coffee beans are ground in a drip process. Since the process is carried out just before the process, there is no chance of the coffee powder being left in the air for a long time.
Therefore, there is no problem such as coffee powder containing moisture and deteriorating flavor.

Incidentally, in the above embodiment, the drip pattern and the heat generating capacity can be selected as desired, but this may be done as necessary.

In addition, the present invention is not limited only to the embodiments described above and shown in the drawings, and it goes without saying that the present invention can be implemented with appropriate modifications within the scope of the invention.

As described above, the present invention allows the crushing mechanism to be automatically operated for a preset time by operating the operation switch, resulting in excellent operability.
