FIG. 5 shows a control circuit. In the microcomputer 101, as shown in the drawing, the electric and electronic parts related to the various inputs and outputs are A / D converters 301 and 302, a switch circuit 303, a drive circuit 304, a display circuit. It is properly connected via 305.

A specific example of the operation control will be described below.
FIG. 6 is a flow chart of the main routine showing the main operation control. After the power is turned on, the initial setting of step # 1 is first performed, and then the processing according to various inputs and outputs is performed (step # 2). Next, when the boiling process (step # 3) is called and the content liquid is lower than the heat retention temperature, that is, when the temperature is low due to the initial water supply or the addition of the content liquid,
When reboiling is set by the reboiling / descaling key 104, the content liquid is controlled to be heated to boiling.

Subsequently, the heat retention process (step # 4) is called to control the content liquid to be kept at a predetermined temperature after initial boiling or reboiling.

Subsequently, timer processing (step # 5)
Is called and the timer is set by the timer setting key 105, delay control is performed so that the boiling operation start time is delayed to the time required to boil the content liquid at the timer setting time and then the boiling operation is started. To do.

Next, when the descaling process (step # 6) is called and the re-boiling / descaling key 104 is operated in the descaling mode, control is performed so that the boiling operation in step # 3 is continued for a predetermined time. However, the removal of scaly should be promoted by the amount of continuous boiling. However, the boiling operation may be repeated intermittently to remove the descaling.

Next, the pump processing subroutine (step #
7) is called, the pouring flow rate is set according to the pressing force of the pressure sensor 103 by the pouring operation unit 102, and the motor 14 of the pouring pump 13 is driven so as to obtain this set pouring flow rate. However, the drive is blocked while the temperature information from the temperature sensor 33 is in the boiling state, before or after the boiling state, or when the liquid level of the content liquid is below the pouring lower limit.
In addition to the prevention of the drive, the pouring standby display 106 is activated.

Finally, after the other processing (step # 8) is completed, the process returns to step # 2, and the above control is repeated thereafter.

FIG. 7 shows a pump operation treatment subroutine. In the dispensing mode in which the dispensing operation key 102 is operated and the pressure sensor 103 is turned on (step # 6).
1), data of the content liquid temperature from the temperature sensor 33 is fetched (# 61a), and as a result, it is determined whether or not the state is boiling or before and after the boiling (# 61b). If it is not in such a state, the content liquid temperature is in a range where there is no danger in pouring, so the process proceeds to the next step, and the liquid amount data from the liquid amount detecting unit 21 is fetched (# 61c). It is determined whether or not (# 61d). If it is not lower than the lower limit water level for pouring, safe pouring is possible, and therefore, the pouring operation starts from step # 65.

If the water is in boiling state or before or after it in step # 61b, or if it is lower than the lower limit water level in step # 61d, it is easy to cause a dangerous pouring state in the splash state. Step # 6 while turning on the pouring standby display 106 until such a state is released
Repeat steps 1a to # 61e.

In the pouring operation after step # 65, the output data associated with the pouring operation pressure from the pressure sensor 103 is first fetched (step # 65).

Next, it is determined whether the sensor output is in the pressurized state or the depressurized state (step # 66). If the sensor output is in the pressurized state, the sensor output is treated as the pressurized data, and the corresponding pressure is applied. Set pressure rank (steps # 67, 6)
8). If the pressure is reduced, the sensor output is treated as the pressure reduction data, and the pressure reduction rank corresponding to the sensor output is set (steps # 69, # 70).

Subsequently, the motor 14 is driven by the rank after the above-mentioned increase / decrease rank is increased / decreased from the current drive rank so that the content liquid is discharged at a flow rate according to the degree of pressing of the discharging operation. (Step # 71).

Such a pouring operation is repeated until the pressure sensor 103 is released from the pouring operation and the pressure sensor 103 is turned off (step # 72).
