The operation control by the control circuit 100 will be described below with reference to the flowcharts shown in FIGS. In the following control, the heater 2 is divided into a main heater for boiling water and a sub-heater for keeping heat, and the heating of the content liquid in the hot water storage tank 1 is controlled.

When the power is turned on, the program starts and the processing of block 1 shown in FIG. 11 is performed.

In this process, first, initialization such as clearing various memories and setting initial data is performed. In the present embodiment, the content liquid is boiled at the same time when the power is turned on, and the control for keeping it warm is automatically achieved.
Therefore, the boiling memory is set by default.

Then, the start of the program is notified by a buzzer sound, and after the program progresses or is repeated according to the power failure determination, a pump operation processing subroutine is executed, and an electric drive is performed depending on whether or not the pouring key is operated. Turn on the pump.

Next, the abnormality detection of various sensors such as the temperature sensor of the water storage section B and the temperature sensor of the hot water storage section A, and the display and processing corresponding thereto are performed. If there is no abnormality, the liquid amount determination processing subroutine is executed, and the hot water storage tank 1 and the amount of liquid in the water storage tank 11 is detected.

In the next blocks 2 and 3 shown in FIG. 12, the processing required when the cooling key and the water supply key are turned on is performed.

In block 2, when the cooling key is turned on, if there is a cooling operation memory, it is the cooling key operation again in the state where the cooling operation mode is actually set, so the cooling output is turned off and the cooling is performed. -The cool LED is turned off, the cooling operation memory and the cooling timer are reset to release the cooling operation mode, and when there is no memory during the cooling operation, the boiling of the content liquid in the hot water storage tank 1 is completed and the water is sent to the water storage tank 11. Time point (in the present invention, it may be any time point after the start of boiling water in the hot water storage tank 1 and before this water feeding time)
In order to cope with the fact that the cooling means 12 rises slowly, the cooling operation memory is set, the cooling timer is started, and the cooling operation mode is entered.

As a result, each time the cooling key is turned on, the cooling operation mode is set and released by the rotary system.

In block 3, when the water supply key is turned on, if the water is not kept warm, the boiling water in the hot water storage tank 1 has not been completed. Therefore, the water supply is not performed, and NG is notified as an operation error.

While the temperature is being maintained, the boiling of the content liquid in the hot water storage tank 1 has been completed, and the mode has been switched to the temperature maintaining mode. Therefore, the cooling operation memory is set and the cooling timer is started in order to send water.

As a result, it is possible to simultaneously cool the water in the water storage section B together with the water supply. This is because the rise of cooling in the water storage section B is slow, so that the cooling operation is started at the same time as the water supply. Therefore, the cooling in the water storage tank 11 is started early and the waiting time is shortened.

In the next Glock 4 shown in FIG. 13, when there is a memory during the water heating operation when the water heating key is turned on, it is the operation of the water heating key in the water heating mode, so the heater output is turned off and the boiling The heat retention LED is turned off, the boiling water operation memory is reset, and the boiling water mode is released.

On the other hand, when there is no memory during the water heating operation, the water heating key is operated in a state where the water heating mode is not set, so the water heating operation memory is set to enter the water heating mode setting state.

As a result, in addition to the fact that the water heating is started when the power is turned on, it is possible to manually release and set the water heating mode at any time by the rotary system.

Finally, it is decided whether to proceed to the next block 5 in the figure or to jump to the block 9 shown in FIG. 16 depending on whether or not there is an empty cooking memory.

In block 5 shown in FIG. 13, when the ode mode setting key is turned on, it is determined whether or not the liquid amount in the hot water storage tank 1 is 1 liter or more, and if not, an NG is notified as an operation error.

In the automatic mode, the hot water storage tank 1 and the water storage tank 1 are used for cooling the water by sending the content liquid after boiling in the hot water storage tank 1 to the water storage tank 11 to cool and keep it cool.
The setting of the automatic mode is prohibited because the amount of the liquid that cannot be stored and stored in both the hot water and the hot liquid is sufficient for both of the above cases.

When the liquid amount in the hot water storage tank 1 is 1 liter or more, the operation display LED is turned off and the cooling output is turned off so that even if the cooling operation is performed, it is stopped.

Then, the auto mode memory is set to enter the auto mode setting state, and the buzzer sound and the lighting of the auto LED indicate the auto mode setting state.

In block 6 shown in FIG. 14, processing corresponding to the timer boiling key being turned on is performed.

When the timer boiling key is turned on, the operation display LED is turned off, the cooling output is turned off, and the corresponding timer time LED is turned on and the buzzer is turned on depending on whether the timer boiling set time is 6 hours or 9 hours. The timer boiling mode is set and displayed by the sound and the lighting of the timer boiling LED.

In block 7 of FIG. 15, when the timer auto setting key is turned on, the auto mode operation is performed in accordance with the timer setting time. If the liquid volume is not more than 1 liter, NG is notified and the timer auto is not set.

When the liquid volume is 1 liter or more, the timer is turned on by turning on the timer time LED according to the timer auto set time and the buzzer sound and turning on the timer auto LED as in the case of the timer boiling of the block 6. Set and display the auto mode.

In block 8 shown in FIG. 16, processing is performed depending on whether or not there is a timer memory.

If there is a timer memory, a timer operation is performed to determine whether the post-timer has expired. If the timer has expired, the timer memory is reset to cancel the timer setting, and the process returns to the power failure judging section of block 1 through the other processing shown in FIG.

If the timer has not expired, the process directly returns to the power failure judging section.

In block 9 shown in FIG. 16, if there is a memory during boiling water operation, it is determined whether or not the temperature is 105 ° C. or higher, and if it is 105 ° C. or higher, an empty cooking memory is set and the boiling memory is reset. Make sure to take measures to prevent empty cooking.

In block 10 shown in FIG. 16, when the reboil key is turned on, there is a boiling memory, and if the content liquid in the hot water storage tank 1 is not higher than 80 ° C., the boiling of the content liquid in the boiling water mode is completed. Since it is the operation of the re-boiling key in the state where it has not been performed, the boiling memory is set so that the boiling is continued, and the buzzer sounds to inform that the boiling mode is being performed.

When the content liquid is 80 ° C. or higher, it means that the boiling water is finished in the boiling water mode and the temperature is immediately kept. Therefore, the boiling memory is reset and a buzzer sound is issued to inform that there is no need for the boiling water. .

Further, when the reboil key is turned on, there is no boiling memory, and there is no empty cooking memory, the reboil key is operated when not in the water heating mode, and there is no worry of empty cooking. Reset and set the boiling memory so that re-boiling will occur,
This is notified by a buzzer sound.

Although the reboil key is turned on and there is no boiling memory, it is possible to switch to the boiling water mode. However, if there is an empty cooking memory, there is a danger of empty cooking in the boiling water mode unless the content liquid is 80 ° C or less. Therefore, the process returns to the power failure determination unit of block 1 and is processed so that the water heating is not performed as it is. However, if the content liquid is 80 ° C. or lower, there is no concern about empty cooking, so the empty cooking memory is reset and the boiling memory is set so that re-boiling is performed.

In block 11 shown in FIG. 17, it is again determined that there is no emptying memory and the content liquid is 80 ° C. or lower. If this is not satisfied, the process proceeds to step # 1-1 of block 1, The boiling and heat-retaining LEDs are alternately blinked to notify the danger of empty cooking, and after the main heater and sub-heater of the block 1 are controlled to be turned off, the procedure after the power failure determination unit is repeated through other processing to allow empty cooking. Do not be discouraged.

In block 11, there is no empty cooking memory,
Only when it is confirmed that the temperature is 0 ° C. or lower, the boiling memory is set to enable the water heating mode, and the process proceeds to the process of block 12 and subsequent steps shown in FIG. 17, otherwise, the process of block 12 is performed as it is. Move on to.

In block 12, if there is a boiling memory after the above processing, the main heater and the sub heater are turned on to enter the water heating mode, and the boiling LED is turned on.
Is displayed to indicate that it is in the water heating mode, and the process proceeds to block 14 shown in FIG.

If there is no boiling memory in block 12, the sub-heater is turned off when the temperature is 1 ° C. higher than the predetermined temperature because it is in the heat retention mode, and the sub-heater is turned on when the temperature is lower than the predetermined temperature to set the predetermined temperature in the hot water storage tank 1. Make sure that the temperature is kept warm.

Next, moving to the processing of block 13 in FIG. 17,
If it is not being kept cold, the process returns to the process after the power failure determination through the other processes in FIG.

The process proceeds to block 16 shown in FIG. 19 when the water storage tank 11 is on while the cold storage is in progress and not in the auto mode, and when the cold storage is in the auto mode and there is a water storage memory. To do.

Then, when the cold storage is not in the automatic mode and the water storage tank 11 is not on, and when the cold storage is in the automatic mode and there is no water storage memory, the processing shifts to the block 17 shown in FIG. To do.

In block 14 shown in FIG. 18, following the boiling mode process in block 12, while the content liquid in the hot water storage tank 1 does not reach 90 ° C. or higher, the boiling data is reset and the power failure process in FIG. Then, the water heating mode in the hot water storage tank 1 is continued.

When the content liquid reaches 90 ° C. or above,
If the reboil key is turned on, it is determined that the descaling mode is set, and the boiling data is fetched every 30 seconds. If the reboil key is not turned on, the descaling mode is not set. After taking in the boiling data, when the addition of the predetermined boiling data is completed, the process moves to block 15.

Is turned off and the cool LED is blinked to warn of this.

Next, while the temperature of the content liquid in the water storage tank 11 is not lower than 20 ° C., the refrigerating compressor 41 and the fan 104 are turned on, and the cooling LED is turned on to indicate that cooling is being performed. And the cold storage memory so that cooling continues.

When the content liquid falls below 20 ° C, 15 ° C
Refrigeration compressor 41 and fan 1 until the following is reached
04 is kept in the ON state, and if there is a cold storage memory, the cold insulation LED
Is displayed to indicate that cold water can be supplied, and if there is no cold memory, the cooling LED is turned on to indicate that the cooling means continues to operate. And in either case, the compressor off memory is reset so that the cooling means continue to operate.

When the content liquid reaches 15 ° C. or below, the purpose of the auto mode has been achieved.
The ED is turned off, the auto mode memory is reset, and the cold storage memory is set so that the cold storage state is continued.

Next, the floc 18 is treated, and the temperature is 10 ° C.
Refrigerating compressor 41 and fan 10 are as follows.
4 is turned off to stop the cooling operation, the compressor off memory is set, and the cold insulation LED is turned on so that the cold insulation is not displayed and the cooling operation is not performed any more.

If the temperature is not lower than 10 ° C., the cooling operation is stopped if there is an off memory, so the refrigeration compressor 41 and the fan 104 are turned on to restart the cooling operation, and the cold insulation LED is turned on to keep the cold insulation. Continue to display.

If there is no off-memory, the cooling operation is in progress, so the refrigeration compressor 41 and the fan 104 are turned off to prevent further cooling operation, and the cold insulation LED is turned on to indicate that the cold insulation is in progress. To continue.

By the processing in this block 18, 10 ° C.
Cooling is achieved in the range of 15 ° C.

In this embodiment, the cooling means 12 is operated at the same time when the electric pump is operated. However, in the case where the above-mentioned water heating is performed before the operation of the electric pump, it may be performed as necessary. It is also possible to activate the cooling means 12 by making use of such a boiling time so that the cooling means 12 can be started up earlier.

This should be set before the water supply by a predetermined time required. Further, such an early rising process is effective in any mode after that, as long as cooling is performed in the water storage tank 11 with water supply.

Further, the electric pumps 4 and 14 have been described as operating individually, but they may be operated simultaneously.

This is convenient when the pouring of water from the hot water storage section A and the pouring of water from the water storage section B are carried out at the same time, and this is received in one container and mixed.

The cooling means 12 has been described only in the case where the refrigerating cycle is used.
It suffices if it can be cooled to about 15 ° C to 15 ° C, and various known ones such as a freezing mechanism using a Peltier element can be adopted.
