In addition, the setting panel 4 is provided in the control unit 10.
2, a setting switch 39 composed of a plurality of DIP switches is connected, and variables for storing other setting values set by the setting switch 39 are prepared. Further, among these variables and flags, those relating to cold water are prepared regardless of whether or not the cold water supply unit is connected, and the setting switch 39 is used to set that the cold water supply unit is not connected. If left, the CPU ignores the processing related to cold water.

Next, the operation of this embodiment having the above structure will be described. This tea supply machine 100 has a timer 52 of 24 hours system.
The timer 52 turns the power on and off at regular intervals. When the timer 52 turns on the power source, a commercial AC power source is connected to the power source unit 51, and the power source unit 51 supplies a DC current to the control unit 10.

When power is supplied to the microcomputer of the control unit 10, the microcomputer starts executing the program of the main routine shown in FIG. 9, and the CPU initializes the variable area and the flag area in the RAM in step 1010 and sets the setting switch. Each setting is made based on the setting status of each DIP switch in 39.

Here, as the manner of tea supply in the tea supply machine 100, continuous pouring in which tea is dispensed only while the tea button 41a1 is pressed, and a preset quantity of tea when the tea button 41a1 is pressed once are set. There is a fixed amount tea supply that supplies tea, and for the specified amount tea supply, there is a fixed amount of tea 1 that pours out only one cup of tea and a fixed amount of tea that pours out tea in a relatively large container such as a pot. Is prepared. In this embodiment, the tea amount 2 is referred to as pot tea supply and the tea amount 1 is referred to as first tea supply. It is assumed that the setting switch 39 is set in advance to perform pot tea supply and first fixed amount tea supply.

After the initial setting, the CPU determines in step 1020 whether a predetermined switch of the setting panel 42 has been operated within 2 seconds after the power is turned on. During normal use, the timer 52 turns on the power, so the setting panel 42
Is not operated, the CPU judges that it is a normal start-up and performs basic control such as hot water temperature control in steps 1100 to 1
Repeat at 600. The CPU executes the main routine program and executes front panel processing and the like by interrupt processing every 10 milliseconds.

Since the tea supply machine 100 uses the hot water stored in the hot water storage tank 101 for pouring tea, the hot water storage tank 101 needs to store hot water of a predetermined temperature in a required amount. is there. Therefore, the CPU proceeds to step 1100.
The hot water temperature is controlled by controlling the power supply to the heater 21 provided in the hot water storage tank 101 to keep the hot water temperature within a predetermined range.

A flag FS in the hot water temperature control shown in FIG.
Reference numeral 8 indicates whether or not the heater 21 is energized. If the flag FS8 is set to "0", the CPU determines that the heater 21 is not energized and stores hot water in step 1104. It is determined whether the hot water temperature in the tank 101 is below the lower limit of the set range.

The hot water temperature in the hot water storage tank 101 is the hot water temperature sensor 3
1 is detected, and the CPU inputs the detection signals output from the sensors 31 to 38 in the sensor reading process shown in FIG. 30 which is executed in the interrupt process, and substitutes the detection value represented by the detection signal into a variable. There is. Specifically, if the tea discharge tank 140 is full, the variable DL is set to "1", and if not, it is set to "0".
When there are no tea leaves in the tea leaf receiver 161, “1” is assigned to the variable LF, when there are tea leaves, “0” is assigned to the variable LF, and the hot water level is assigned to the variable HL. If it is full, the variable DW is set to "1", and if it is not full, it is set to "0"
And the hot water temperature is assigned to the variable TH1. Although the cold water supply unit is not connected in this embodiment, when the same cold water supply unit is connected, the cold water level is set to the variable CL.
And the water temperature is substituted into the variable TH2.

Immediately after the power is turned on, the hot water in the hot water storage tank 101 is cooled, so the CPU determines in step 1104 that the value of the variable TH1 is smaller than the variable FT12 representing the lower limit of the setting range. , Step 110
At step 6, the energization of the heater 21 is started, and at step 1108, the flag FS8 is set to "1" and the hot water temperature control is ended. Next, when the hot water temperature control is executed, "1" is set in the flag FS8, so the CPU determines in step 1110 whether the value of the variable TH1 exceeds the variable FT11 representing the upper limit of the set range. At this time,
If the hot water temperature does not exceed the upper limit of the set range, the hot water temperature process is ended without doing anything. If the hot water temperature exceeds the upper limit, energization of the heater 21 is stopped in step 1112 and the flag FS8 is set in step 1114. Is set to "0" and the hot water temperature control is ended. As a result, the hot water temperature in the hot water storage tank 101 is maintained between the lower limit heater energization start temperature FT11 and the upper limit heater energization end temperature FT12.

Further, the CPU controls the hot water level in step 1200 in the same manner as the hot water temperature control described above, and controls the energization of the hot water supply valve 22 provided in the hot water supply passage for the hot water storage tank 101 to set the predetermined water level. Keep it within the range of. That is, the CPU executes step 1 of the hot water level control shown in FIG.
If it is determined in 202 that the water supply to the hot water storage tank 101 is set to automatic water supply, the flag F is determined in step 1204.
Based on the set value in S7, it is determined whether or not water is being supplied. Initially, the flag FS7 is set to "0",
The CPU determines in step 1206 whether or not the water level of the hot water storage tank 101 assigned to the variable HL is smaller than the variable FHL2 preset as the water level requiring water supply. If water supply is not required, the hot water level control is ended without doing anything, but if water supply is required, the CPU proceeds to step 120.
At 8 while energizing the hot water supply valve 22 to open the valve,
In step 1210, the flag FS7 is set to "1". When the hot water supply valve 22 is energized in this way, the pumping pump 203 in the water supply unit 200 is also energized via the magnet connector 23, so the pumping pump 203 pumps up the water in the water receiving portion 202, and Water is supplied into the hot water storage tank 101 via the water supply valve 22.

When the set value of the flag FS7 is changed, the CPU executes step 120 when the hot water level control is executed next time.
It is determined in 4 that the water is being supplied, and in step 1212 it is determined whether or not the water level of the hot water storage tank 101 substituted for the variable HL is larger than the variable FHL1 preset as the water level of full water. If it is not full, the process ends without doing anything, but if it is full, the CPU stops energizing the hot water supply valve 22 in step 1214 to close the valve, and proceeds to step 1216. Flag FS7
Is set to "0".

The hot water storage tank 101 is controlled by such hot water level control.
The water level of is maintained within a predetermined range. For the automatic water supply setting, the hot water automatic water supply button 4 on the setting panel 42
2a8 is operated to select ON or OFF.

Now, it is assumed that hot water of a predetermined temperature is stored in the hot water storage tank 101 in a full state by the above-mentioned hot water temperature control and hot water level control, and in this state, the user of the front panel 41 in order to put tea in the pot. It is assumed that the pot tea supply button 41a5 is pressed and then the tea button 41a1 is pressed. In addition,
Tea is the front door 11 from the pouring hole 111a of the pouring liquid receiving tray 111.
Since it is dripped into the recess 112 of 0,
A pipe line is connected from 1a to the pot.

The CPU executes the front panel processing shown in FIG. 25 every 10 milliseconds, and when the user presses the pot tea feeding button 41a5, the CPU performs the pot tea feeding button processing shown in FIG. 27 in the front panel processing. In step 2122, it is determined that the pot tea supply button 41a5 has changed from off to on, and in step 2124, "0" is assigned to the counter variable T0 and "1500" is assigned to the counter variable T1. To do. Here, the counter variable T0 represents the elapsed time after the continuous pouring button 41a4 is pressed, and the counter variable T1 is a variable representing the elapsed time after the pot tea supply button 41a5 is pressed. When the button 41a5 is pressed, "1500" is assigned to the counter variable T1 as described above, and if it is determined in step 2126 that the variable T1 is not "0", the value of the variable T1 is set to "2". Subtract only 1 ".

When "1500" is assigned to the counter variable T1 and "1" is subtracted every 10 milliseconds, the variable T1 becomes a positive value only for 15 seconds. Therefore, when the counter variable T1 is a positive value, it can be detected that it is less than 15 seconds after the pot tea supply button 41a5 is pressed.

Note that the CPU executes the continuous pouring button process shown in FIG. 26 in the same manner as the pot tea feeding button process in the front panel process, and in step 2102 of the continuous pouring button process. When it is determined that the continuous dispensing button 41a4 has changed from off to on, "1500" is substituted for the counter variable T0 in step 2104 and "0" is substituted for the counter variable T1. When it is determined that the variable T0 is not "0", the counter variable T0 is subtracted by "1" at step 2108. Therefore, also in this case, it can be detected whether or not it is less than 15 seconds after the continuous dispensing button 41a4 is pressed.

Further, when the continuous pouring button 41a4 is pushed, "0" is forcibly substituted for the counter variable T0 corresponding to the pot tea feeding button 41a5, and when the pot tea feeding button 41a5 is pushed. "0" is set in the counter variable T1 corresponding to the continuous dispensing button 41a4.
Since the button is pushed, the button that was pressed later becomes valid, and if you make a mistake, you can correct it by simply pressing the correct button.

1 after pressing the pot tea supply button 41a5
If you press the tea button 41a1 within 5 seconds, CP
U is the tea button 41a1 in step 2142 in the tea button processing shown in FIG. 28 in the front panel processing.
Is determined to be ON, and in step 2144, "1" is set to the flag FB0 indicating the state of the tea button 41a1. In addition, from pressing the pot tea supply button 41a5 to pressing the tea button 41a1, the CPU determines in step 2146 that the tea button 41a1 is off, and sets the flag FB0 to "0" in step 2148. There is.

The CPU executes hot water temperature control and hot water level control in the main routine as well as the tea supply selection process shown in FIG. 12, and the flag FB0 is executed at step 1302 in the same process.
Is set to "1". While the tea button 41a1 is not pressed, the flag FB0 is set to "0" in the front panel processing, and the tea supply selection processing is ended without doing anything. However, when the tea button is pressed, the CPU proceeds to step 1302. It is determined that "1" is set in the flag FB0, the flag FB0 is reset in step 1304, and the tea supply start condition check process shown in FIG. 16 is executed in step 1306.

In the tea supply start condition check processing, various conditions for starting tea supply are checked, and the result is flag FC1.
Set to CP when you can start tea supply
U sets "0" to the flag FC1 in step 3020, and if the conditions for starting tea supply are not satisfied, step 30
At 22, the flag FC1 is set to "1".

The states in which the tea supply cannot be started include the case where the tea supply cannot be performed because other processing is being executed, and the case where the conditions for the tea supply are not satisfied. The setting of the flag indicating each state and the detection of the sensor are performed. Judge based on the value of the variable that represents the result. In the present embodiment, when it is determined that the setting panel 42 is operated based on the flag FS1 (step 3002), hot water is poured out based on the flag FS3 as a case where other processing is being executed. If it is determined that the cold water supply unit is connected (step 3006), and if it is determined that the cold water of the cold water supply unit is being drained based on the flag FS2 (step 3004). , And when it is determined that cold water is being poured out based on the flag FS4 (step 3008).

When the condition for supplying tea is not satisfied, when it is determined that the drain tank 204 in the water supply unit is full based on the variable DW representing the detection result of the drain sensor 33 (step 3010). When the value of the variable HL representing the detection result of the hot water level sensor 32 becomes equal to or less than the variable FHL3 representing the lowest water level of the hot water storage tank 101 and it is determined that the amount of hot water is exhausted (step 3012), the tea discharge sensor 37 is activated. When it is determined that the tea discharge tank 140 is full based on the variable DL indicating the detection result (step 3014), the tea leaves in the tea leaf receiver 161 are determined based on the variable LF indicating the detection result of the tea leaf sensor 38. There is a time (step 3016) when it is determined that the data is gone.

However, in the tea supply machine 100, the tea discharge tank 1
When 40 is full and when there are no tea leaves in the tea leaf receiver 161, the tea supply is not immediately disabled. This is because even if the tea discharge tank 140 is full, there is no problem unless the tea is discharged, and even if the tea leaves in the tea leaf receiver 161 are exhausted, there is no problem unless the tea leaves are replaced.

Therefore, when the tea discharge tank 140 is full and when the tea leaves in the tea leaf receiver 161 are exhausted, the CPU determines in step 3018 the value of the variable AM1 representing the amount of tea dispensed after the tea leaves are exchanged. And the value of the variable FAM0 representing the amount of tea leaf exchange dispensed is compared, and if the variable AM1 is smaller than the variable FAM0 and the exchange of tea leaves is not required, the flag FC is given in step 3020 to permit the start of tea supply.
Set "0" to 1.

By doing so, it is possible to avoid a situation where the tea supply becomes impossible as much as possible.

The CPU executes the tea supply start condition check processing described above to set the flag FC1 and then returns to the tea supply selection processing to determine in step 1308 whether tea supply can be started based on the flag FC1. Then, the same flag FC1
Is set to "1" and the tea supply cannot be started, the tea supply selection process is terminated without starting the tea supply.

On the other hand, if the tea supply can be started, the CPU proceeds to step 131 based on the values of the counter variables T0 and T1.
At 0 and step 1312, it is determined whether the continuous pouring button 41a4 or the pot tea supply button 41a5 is pressed within 15 seconds before the tea button 41a1 is pressed. As described above, since the tea supply button 41a5 is pressed and then the tea supply button 41a1 is pressed, only the counter variable T1 has a positive value, and the CPU sets the pot supply using the setting switch 39 in step 1314. It is determined whether or not is on.

If the setting switch 39 is set not to supply the pot tea at the time of start-up, the CPU executes the continuous pouring process for pouring the tea only while pressing the tea button 41a1 in step 1318. However, since it is currently set to perform pot tea supply, the CPU starts execution of pot tea supply processing in step 1316.

In the pot tea supply processing, the tea pouring is executed until the tea pouring amount reaches a preset predetermined amount. The setting and measurement of the tea pouring amount will be described here.

The setting amount of tea is set by operating the setting panel 42. The CPU executes the setting panel processing shown in FIG. 23 every 10 milliseconds during execution of the main routine, scans the operation status of each touch switch in step 2202, and prepares for each touch switch in step 2204. If the touch switch is turned on, the button flags FB1 to FB4 ... Are set to "1", and if the touch switch is turned off, "0" is set. In step 2206, the counter variables T0 and T1 are set similarly to the panel. With the operation timer variable FT, it is measured whether or not it is within 10 seconds after the touch switch on the setting panel is finally pressed. That is, the CPU substitutes "1000" into the panel operation timer variable FT when any one of the touch switches is turned on, and thereafter, the value of the panel operation timer variable FT is set every time the setting panel process is executed. "1" unless is "0"
We are subtracting one by one.

It is assumed that when the power is turned on, the tea amount 1 lamp 42b1 on the setting panel 42 is lit, and the display switching button 42a1 is pressed to set the pouring amount in the pot tea supply. This allows
The CPU sets "1" to the button flag FB1 in the setting panel processing.
Is set, and the panel operation timer variable FT is set to "1.
000 "is set.

On the other hand, the CPU executes the setting panel operation processing shown in FIG. 18 in step 1400 of the main routine, and determines in step 1402 whether the panel operation is started based on the value of the panel operation timer variable FT. .
Since the value of the panel operation timer variable FT is now positive, the CPU sets 1404 in the flag FS1 indicating that the panel operation is in progress, and also sets 1 in the button flag FB1. Therefore, the CPU determines in step 1406 that the display switching button 42a1 has been pressed, and executes the display switching button processing shown in FIG. 19 in step 1408.

In the display switching button process, the CPU increases the pointer variable SL representing the setting target by "1". Here, in the initial state, the pointer variable SL is set to "1" and the dispensing amount for one cup in the first fixed amount tea supply is set, but it is set to "2" by pressing the display switching button 42a1. The target to be set is the amount dispensed to the pot in pot tea supply. In addition, when the value of the pointer variable exceeds "8" in step 1432 and step 1434, it is returned to "1", and in step 1436, the setting of the button flag FB1 is reset to "0".

By the way, in order to control the display element on the setting panel, the CPU executes the display control process shown in FIG. 24 by the interrupt process, and the CPU executes step 2502.
Read the data value to be displayed in step 2504
The display is controlled based on the data value read in.
In the initial setting, the CPU substitutes "1" into the pointer variable SL and also substitutes the value of the variable DT0 (1 to 8) into the variable WK (1 to 8) of the work area. The tea fixed quantity 1 lamp 42b1 is turned on in order to indicate that the setting target is the discharged quantity in the first fixed amount tea supply corresponding to the value of the variable SL, and the first fixed amount tea supply amount and the pot. The value of the variable WK (1) in which the first fixed amount tea supply amount is stored is displayed on the first display portion 42c1 which displays the tea supply amount.

However, since the pointer variable SL has become "2", the CPU turns on the tea quantity 2 lamp 42b2 to indicate that the setting object is the pouring amount in the pot tea supply, and together with this, the first display. The value of the variable WK (2) in which the amount of pot tea dispensed is stored is displayed in the portion 42c1. Further, when the display switching button 42a1 is pressed to set the hot water temperature or the water temperature, the same processing as described above is performed.

When the tea quantity 2 lamp 42b2 lights up,
By looking at the display of the first display portion 42c1, the upper button 42a2 is pressed to increase the dispensing amount, and the lower button 42a3 is pressed to decrease the dispensing amount. If the upper button 42a2 is pressed to increase the dispensing amount, "1" is set to the button flag FB2 in the setting panel process, and in step 1410 of the setting panel operation process, based on the button flag FB2, step 1412 is executed. Executes the upper button process.

In step 1440 of the up button processing shown in FIG. 20, the CPU adds the variable DT1 (2) which is the increase / decrease value of the setting object corresponding to the value of the pointer variable SL to the variable WK (2) of the work area. In step 1442 and step 1444, the value of the variable WK (2) is adjusted so as not to be larger than the value of the constant DT2 (2) that stores the maximum value of the setting target, and in step 1446, the button flag FB2 is set. Is returned to "0".

Further, when the lower button 42a3 is pressed to decrease the dispensed amount, "1" is set in the button flag FB3 in the setting panel processing in the same manner, and step 141
At step 6, the down button processing shown in FIG. 21 is executed to decrease the work area variable WK (2).

When the display on the first display section 42c1 reaches an appropriate value, the setting button 42a4 is pressed. The same setting button 42a
When 4 is pressed, the CPU executes the button flag FB in the setting panel processing.
4 is set to "1", and the CPU executes the setting button processing of step 1420 based on the value of the button flag FB4 in step 1418 of the setting panel operation processing.

In the setting button processing shown in FIG. 22, the CPU
Is a variable DT0 that stores the set value in step 1460.
The variable WK (2) of the work area corresponding to the current setting target is written in (2), and "0" is set in the button flag FB4 in step 1462, and step 146
At 4, "0" is substituted into the panel operation timer variable FT. In this setting panel operation process, the panel operation timer variable FT is also used as an ending condition in the operation of the setting panel, and the setting panel operation process is ended when the value of the variable FT becomes “0”. I have to.

The CPU is step 1 of the setting panel operation processing.
If it is determined in 422 that the value of the variable FT is “0”, the setting value DT (2) corresponding to the current setting target is read into the variable WK (2) in the work area in step 1424. Since the opposite operation is performed when 42a4 is pressed, this reading does not change the value of the variable WK (2) in the work area.

However, if the setting button 42a4 is not pressed after the upper button 42a2 and the lower button 42a3 are pressed, the panel operation timer variable FT is set after 10 seconds.
Value becomes "0", and the CPU determines in step 1422 that the ending condition is satisfied and reads the set value into the work area in step 1424. When the setting button 42a4 was pressed, the value of the work area did not change because the setting value was read into the work area after writing the value of the work area to the setting value. Since the value of the set value is read into the work area without being written in, the value of the work area returns to the value before the operation of the setting panel 42 was started. That is, the upper button 42a2 and the lower button 42a3
Even if the display of the set value is changed by pressing, if the setting button 42a4 is not pressed within 10 seconds, the change is invalid.

Thereafter, the CPU sets "1" in the flag FS1 to indicate that the panel operation is completed.
"0" is set and the setting panel operation process is ended.

On the other hand, the CPU executes the tea pouring amount measurement process shown in FIG. 29 by interrupt processing every 10 milliseconds, and at step 2302, the tea pouring amount is measured based on the set value of the flag FS5 indicating that tea is being poured. To determine whether or not.

The tea pouring amount is measured as the tea pouring time, and when it is determined in step 2302 that the tea is being poured out, the CPU outputs three types of tea in steps 2304 to 2308. The value of the variable AM2 representing the amount of dispensed per unit time is added to the variables AM0, AM1, and AM3 representing the amount of dispensed.

Returning to the pot tea supply processing, the CPU substitutes "0" into the variable AM3 representing the current pouring amount in order to measure the pouring amount in step 3302, and in step 3304, sets the tea feeding state. "1" is set to the flag FS5, and the tea pouring valve 25 is energized to open the same in step 3306. At this time, the flag FS6 indicating immediately after the exchange of tea leaves is set to "0" in order to indicate that hot water has been poured into the tea leaves in relation to the processing of the tea amount 1 described later.

When the tea pouring valve 25 is opened, the hot water storage tank 10 is opened.
Hot water is poured onto the tea strainer 131 from 1 through a pipe, tea is poured out in the tea strainer 131 and dropped on the pour liquid receiving tray 111, and then the tea pour liquid receiving tray 111 is poured out. It is supplied into the pot through a pipe connected to the hole 111a.

When the tea supply is started in this way, the CPU
Determines in step 3308 whether the drainage tank 204 is full based on the value of the variable DW, and in step 3310 a variable HL representing the water level in the hot water storage tank 101 and a variable FHL3 representing the water level that cannot be supplied with water. It is determined whether hot water can be supplied based on the above, and if it is possible to continue the tea supply, in step 3312, the value of the variable AM1 representing the amount of tea dispensed after the tea leaf replacement and the tea pouring serving as a guide for the tea leaf replacement. The value of the variable FAM0 representing the output is compared to determine whether tea leaf replacement is necessary.

If it is not necessary to replace the tea leaves, the CPU, in step 3314, sets the variable AM3 representing the current pouring amount of tea.
Is reached to the value of the variable DT0 (2) set as the pouring amount in the pot tea supply, and while the variable AM3 representing the present pouring amount is smaller, step 33
Returning to 08, the pot tea supply processing is continued.

Since the pouring amount in the pot tea supply processing is relatively large, the value of the variable AM1 representing the pouring amount of tea after the tea leaves are exchanged during the tea pouring is the tea pouring amount as a guide for the tea leaf exchange. It becomes larger than the variable FAM0 that indicates that it is necessary to replace the tea leaves. Then, the CPU determines in step 3312 that the value of the variable AM1 has become larger than the value of the variable FAM0, and in step 3316, determines whether or not the tea discharge tank 140 is full based on the value of the variable DL. At 3318, it is determined based on the value of the variable LF whether or not the tea leaves in the tea leaf receiver 161 are exhausted, and if both tea leaves can be exchanged, step 332 is performed.
At 0, the tea leaf exchange shown in FIG. 17 is performed.

In the same tea leaf exchange, the CPU executes step 350.
In step 2, the flag FS5 indicating the tea supply state is set to "0", and in step 3504 the tea pouring valve 25 is closed to temporarily stop the tea supply. Then, step 3506
Then, based on the setting of the setting switch 39, it is determined whether or not the tea leaf time difference exchange is set. The time difference exchange of tea leaves is a process for removing the water contained in the tea leaves in the tea strainer 131 and then discarding it in the tea discharge tank 140. Only when the time difference exchange of tea leaves is set, step 3508 is performed.
The CPU waits for 5 seconds without doing anything, and then the CPU energizes the tea exchange motor 29 in step 3510.

When the tea exchange motor 29 starts to rotate,
The tea leaves in the strainer 131 are discarded and new tea leaves are replenished. During that time, the CPU determines in step 3512 whether the micro switch 36 is turned off, and the micro switch 36 is turned off. It is determined that the rotating shaft of the cod roe tea exchange motor 29 has rotated once to the initial position, and at step 3514, a variable CT representing the number of exchanges of the tea leaves.
The value of is increased by "1" and step 351
At 6, the power supply to the tea leaf exchange motor 29 is stopped.

Thereafter, the CPU sets "1" to the flag FS5 indicating the tea supply state in step 3518, energizes the tea pouring valve 25 in step 3520 to restart the tea pouring, and proceeds to step 3522. "1" is set to the flag FS6 indicating that tea leaves have been exchanged, and the tea leaf exchange is completed.

In this way, when the tea supply in the pot is continued while the tea leaves are exchanged on the way, the variable A representing the current pouring amount is obtained.
The value of M3 gradually increases and becomes larger than the variable DT0 (2) representing the set value of pot tea supply. Therefore, when the CPU determines in step 3314 of the pot tea supply processing that the value of the same variable AM3 has become larger than the variable DT0 (2), it sets "0" to the flag FS5 indicating the tea supply state in step 3322 and also executes step At 3324, the power supply to the tea pouring valve 25 is stopped. Tea supply is stopped by stopping the power supply to the tea pouring valve 25, and the pot tea supply process is ended.

The drainage tank 204 may become full before the pouring amount reaches the set value for pot tea supply, or the hot water storage tank 10
Step 3322 and step 3322 also when the remaining amount of hot water in 1 runs out, or when the tea discharge tank 140 is full or the tea leaves in the tea leaf receiver 161 are exhausted when the tea leaves need to be replaced. At 3324, the tea supply is interrupted to end the pot tea supply.

Up to now, the pot tea supply, in which a large amount of tea such as a pot is replenished in a container such as a pot, has been described so far. However, when the tea supply device 100 presses the tea button 41a1 once. It is possible to execute the first fixed amount tea supply in which one cup of tea is poured.

When the user presses the tea button 41a1 without pressing the pot tea supply button 41a5 or the like, the CPU causes the flag FB in the tea button processing in the front panel processing.
Since "1" is set to 0, it is determined in step 1302 of the tea supply selection process in the main routine that the tea button is turned on based on the flag FB0. Thereafter, as in the case of pot tea supply, after resetting the flag FB0 in step 1304, a tea supply start condition check is performed in step 1306, and if tea supply can be started, it is determined in steps 1310 and 1312 15 Continuous pouring button 41a4 or pot tea supply button 41a5 within seconds
It is determined whether or not is pressed.

However, this time, only the tea button 41a1 is being pressed, and the CPU judges that neither button is pressed, and in step 1320, it is judged whether or not the setting of the first fixed amount tea supply is ON. However, since the setting of the first fixed amount tea supply is turned on by the setting switch 39 in advance, the CPU executes the first fixed amount tea supply processing shown in FIG. 14 in step 1322.

When starting the first fixed amount tea supply, as in the case of pot tea supply, the CPU substitutes "0" into the variable AM3 representing the current pouring amount in step 3202, and proceeds to step 3
In step 204, the flag FS5 indicating the tea supply state is set to "1", and in step 3206 the tea pouring valve 25 is energized to start the tea supply.

The condition for ending the first fixed amount tea supply is basically that the value of the variable AM3 representing the current supply amount exceeds the set value DT0 (1) for storing the first fixed amount tea supply amount. It is in a state of being.

By the way, when the tea leaves are replaced, the tea strainer 13
Although new tea leaves are supplied to the inside of 1, the dry tea leaves are supplied, so that some of the hot water poured thereafter is absorbed by the tea leaves themselves. Therefore, when comparing the amount of hot water poured into the tea leaves with the set value in the first fixed amount tea supply, for the cup poured into the teacup immediately after the tea leaves are replaced, only the amount absorbed by the tea leaves itself The amount of tea poured out will decrease. Although this is not a serious problem in pot tea supply with a large amount to be dispensed, it is a non-negligible error when an appropriate amount of tea is drunk, such as in the first fixed amount tea supply.

Since the flag FS6 is set to "1" when the tea leaves are exchanged as described above, the CPU determines in step 3208 based on the flag FS6 whether or not the tea leaves have been exchanged immediately. If it is not immediately after the replacement, in step 3210, the tea is continuously dispensed until the value of the variable AM3 representing the current tea dispense amount exceeds the set value DT0 (1) of the first fixed amount tea supply.

However, when the flag FS6 is set to "1" and it is judged that the tea leaves have just been exchanged,
In step 3211, the CPU sets "0" in the flag FS6 indicating immediately after the tea exchange to indicate that hot water has been poured into the tea leaves, and then in step 3212, the value of the variable AM3 that indicates the amount of tea dispensed this time. The pouring is continued until the value becomes larger than the value obtained by adding the set value DT0 (1) and the variable FAM3 representing the water absorption amount of tea leaves. That is, the amount of hot water poured into the tea strainer 131 is (DT0 (1) + FAM3), but the tea leaves in the tea strainer 131 absorb only (FAM3) of hot water and (DT0 (1 )) Will be poured only.

As a result, even when tea is supplied immediately after the tea leaves are exchanged, the same amount of tea as in the normal case can be dispensed.

Even when the first fixed amount tea supply is being performed, the pouring amount AM1 after the tea leaf exchange is measured. It may be larger than the standard pouring amount FAM0.

However, the tea supply for one cup of tea is completed in just a few seconds, and if the tea supply is interrupted until the tea supply is interrupted, it takes an extra time and is often inconvenient. Further, even if the amount of tea to be poured out slightly exceeding the amount of tea to be replaced, the concentration of tea does not change suddenly.

Therefore, in the case of the first fixed amount tea supply, it is necessary to supply tea until one cup of tea is dispensed in step 3210 or step 3212, and then it is necessary to replace the tea leaves in step 3214. Determine whether or not. When it is necessary to replace the tea leaves, it is determined in step 3222 whether or not the tea discharge tank 140 is full, as in the case of pot tea supply, and in step 3224 the tea leaf receiver 16 is supplied.
It is judged whether or not the tea leaves in 1 have run out, and if both are in a state where the tea leaves can be exchanged, the tea leaves are exchanged in step 3226.

If it is not necessary or necessary to replace the tea leaves, the CPU sets "0" in the flag FS5 indicating the tea supply state in step 3216, and then dispenses the tea in step 3218. The energization of the valve 25 is stopped and the first fixed amount tea supply process is ended.

Now, in the two quantitative tea supply described above,
The amount of tea can be dispensed by pressing the tea button 41a1 once, but in the case of a large cup or a small cup of tea, an appropriate amount of tea cannot be dispensed by a fixed amount tea supply.

For such a case, the tea supply machine 100 can carry out continuous pouring while pouring tea only while pressing the tea button 41a1. In order to perform the continuous pouring, the user presses the continuous pouring button 41a4 and then the tea button 41a1 until the required amount of tea is poured.
Just press and hold.

When the continuous pouring button 41a4 is pressed, the CPU executes step 210 of the continuous pouring button processing as described above.
When "1500" is assigned to the variable T0 for the counter in step 4 and the tea button 41a1 is pressed, the continuous pouring button 4 is pressed within 15 seconds in step 1310 in the tea supply selection process.
Since it is determined that 1a4 has been pressed, the CPU starts the continuous dispensing process shown in FIG.

Unlike the case of tea quantity 1 and tea quantity 2,
Since the continuous pouring does not end when the tea pouring amount reaches the predetermined value, the CPU does not substitute “0” for the variable AM3 representing the present pouring amount, and proceeds to step 31.
In step 02, "1" is set in the flag FS5 indicating the tea supply state, and in step 3104, the tea pouring valve 25 is energized to start the tea supply. Also in this case, in order to indicate that hot water has been poured into the tea leaves in relation to the processing of the tea amount 1, "0" is set in the flag FS6 indicating immediately after the tea leaves are exchanged.

When the tea supply is started, the CPU proceeds to step 31.
At 06, it is determined whether or not the drain tank 204 is full based on the value of the variable DW, and step 3108
Determines whether hot water can be supplied based on a variable HL representing the water level in the hot water storage tank 101 and a variable FHL3 representing the water level that cannot be supplied with water. Variable A that represents the amount of tea to be poured later
The value of M1 is compared with the value of the variable FAM0 that represents the amount of tea dispensed, which is a guide for tea leaf exchange, to determine whether tea leaf exchange is necessary.

If it is not necessary to replace the tea leaves, the CPU determines in step 3112 whether "0" is set in the flag FB1 representing the state of the tea button 41a1 and sets "1" in the flag FB1. If it is present, continuous dispensing is continued, but if "0" is set in the same flag FB1, continuous dispensing is terminated. .

In the tea button processing, the tea button 41a1
When is pressed to turn on, the flag FB0 is set to "1", and when the tea button 41a1 is released to turn off, the flag FB0 is set to "0". Therefore, when the user removes the finger from the tea button 41a1 when he / she sees the amount of tea poured into the teacup and determines that the tea has been poured in an appropriate amount,
The CPU sets "0" to the flag FB0 by the tea button processing. Therefore, while the user continues to press the tea button 41a1, the flag FB0 is set to "1", and the continuous dispensing process is continued to dispense tea.

However, when the user releases the finger from the tea button 41a1, "0" is set in the flag FB0 and the CPU
Determines in step 3112 that the tea button 41a1 has been turned off based on the setting of the flag FB0, sets "0" in the flag FS5 representing the tea supply state in step 3114, and then dispenses tea in step 3116. The electricity supply to the outlet valve 25 is stopped and the tea supply is finished.

When the drainage tank 204 becomes full before the tea button 41a1 is released, the remaining amount of hot water in the hot water storage tank 101 is exhausted, or when it becomes necessary to replace the tea leaves, the discharge tea tank 140 becomes full. Or tea leaf receiver 161
Step 311 when the inner tea leaves are gone
4 and step 3116 complete the tea supply.

By the way, during the execution of the above-mentioned main routine, the CPU performs the management display processing at step 1600, and the setting button 42a4 and the display switching button 42a1 are simultaneously pressed at step 1601 shown in FIG. It is determined whether or not, and if not pressed at the same time, the management display process is terminated without doing anything.

In the management display, the CPU proceeds to step 1602.
The value of the variable AM0 representing the total pouring amount is set to the variable amount DT0 set as the pouring amount for one teacup in the first fixed amount tea supply.
Divide by the value of (1) to calculate the number of cups of tea that have been poured so far (only tea quantity 1). At this time, four digits are prepared as the calculation area, and when the number of digits is four or more, the upper digits are ignored.

By the way, each time the tea leaves are exchanged, the variable C is changed.
The value of T is increased by “1”, and the CPU displays the value of the variable CT representing the number of times of tea leaf replacement on the first display portion 42c1 of the setting panel 42 in step 1604. Since the first display unit 42c1 has only a three-digit display area, the CPU displays only the lower three digits of the number of tea leaf exchanges stored in the variable CT.

After the first display portion 42c1 is displayed, the CPU displays the upper two digits of the tea pouring cup number calculated in step 1602 on the second display portion 42c2 in step 1606 and the lower two digits in step 1608. Is displayed on the third display section 42c3.

The administrator can know the number of tea leaf exchanges in a predetermined period by recording the number of tea leaf exchanges at the present time by looking at the display of the first display section 42c1 and subtracting the previous number of tea leaf exchanges.

In this embodiment, the administrator must record the previous number of tea leaf exchanges. However, when the setting button 42a4 is pressed, the number of tea leaf exchanges currently being displayed is written in the storage area. , Up button 42
When the user presses a2 or the down button 42a3, the data written in the storage area may be sequentially displayed on the first display section 42c1, and the administrator may record the number of tea leaf exchanges within a predetermined period. .

It should be noted that the displayed number of tea leaf exchanges is ignored because the upper digits exceeding three digits are ignored, and therefore it is considered that the carry has been carried when the number of times of this time is smaller than the number of times of last time. In normal use, it is considered that the carry will not be carried twice during the management period.
00 ”is added and the previous number of tea leaf exchanges is subtracted.

Further, the second display portion 42c2 and the third display portion 4
For 2c3, the administrator can know the current number of pouring cups by multiplying the display value of the second display portion 42c2 by "100" and adding the value to the display value of the third display portion 42c3. In this case as well, since the upper digits exceeding four digits are ignored, when the number of times this time is smaller than the number of times of the previous time, it may be calculated as a carry.

Furthermore, the upper button 42a3 and the lower button 42
When a2 and a2 are pressed at the same time, the CPU detects this in step 1610 and returns a predetermined variable to "0" in step 1612.

After the start of the management display, the CPU starts timing, and if it is determined in step 1614 that 15 seconds have elapsed, the management display is ended and the processing of the main routine is restarted.

The operation when the setting panel 42 is not operated at the time of starting the microcomputer has been described above, but it is assumed that the administrator turns on the power while pressing a predetermined switch of the setting panel 42.

When the CPU is started up in this manner, the CPU makes initial settings in step 1010 and then, in step 1020, the setting panel 42 within 2 seconds after the power is turned on.
It is determined whether or not a predetermined switch is operated, and when the switch is operated, it is determined that the startup is not normally performed, and the setting back mode processing is executed. In this back mode processing, settings can be made so that the settings are usually not changed so much, and if the settings are completed and no operation is performed within a fixed time, the normal operation is restored.

Although not described in the above embodiment, the hot water pouring process may be performed by energizing the hot water pouring valve 24 instead of energizing the tea pouring valve 25. Also, the set number of pouring cups for tea exchange DT0 (6)
When "0" is set to 0, the dispensed amount FAM0, which is a guideline for tea leaf replacement, is also "0", but when the canister 162 is not replenished with tea leaves and the necessity of tea leaf replacement is determined in the above embodiment. (Step 3018, Step 3110, Step 3214, Step 3312)
When it is determined that it is not necessary to replace the tea leaves when the same dispensed amount FAM0 is “0”, the tea button 41a1
The hot water can be poured out when is pressed.

In addition, the reset button 4 on the setting panel 42 is used as an operation which is not described in the above embodiment.
When 2a5 is pressed, the CPU resets the tea dispenser 100 to the state immediately after the power supply, and when the tea leaf manual replacement button 42a6 is pressed, the tea leaf replacement motor 29 is energized to replace the tea leaf and the boiling button 42a7 is pushed. Sometimes, the hot water in the hot water storage tank 101 is boiled once. Furthermore, CPU
Lights the pouring lamp 41b4 on the front panel when pouring tea or the like, blinks the tea adjusting lamp 41b1 during tea leaf replacement to display the operating state to the user, and the tea discharge sensor 37. The value of the variable DL indicating the detection result of the above, the variable LF indicating the detection result of the tea leaf sensor 38, and the variable DW indicating the detection result of the drainage sensor 33 is “1”.
If it is, the processing for turning on the full tea discharge lamp 42b13, the cut tea leaves lamp 42b11, and the full discharge water lamp 42b12 in the setting panel 42 is additionally performed.
