<Example> Hereinafter, the boiler-cooker of the present invention will be described in more detail by taking the bean kneader 70 as an example.

First Embodiment A kneading machine 70 of this embodiment is provided with a ball pot 3, an agitator 5, a gas pot 25 and a controller 80 as shown in FIG. The same members as those described in the conventional example are designated by the same reference numerals, and the description thereof will be partially omitted.

The pot is not limited to the bowl type.

The stirring means is not limited to the agitator 5 described above, and for example, center rotation, oblique axis rotation, horizontal type hot kneader or the like can be used.

The heating means is not limited to the gas kettle 25 described above, and for example, a heat generator using electric power, kerosene, or steam as a heat source can be used. The valve 71 for adjusting the heating output was the direct acting transformer shown in FIG. The valve 71 is composed of a diaphragm 72, a spring 73 and a main valve 74. Then, the movable portion 75 connected to the upper end of the spring 73 is moved up and down by the solenoid 76 to adjust the main valve 74. In this embodiment, the gas flow rate is adjusted in 15 steps depending on the position of the main valve 74.

As shown in FIG. 4, the control device 80 includes a CPU 81 (central processing unit), RAM 82 (storage means), ROMs 86 and 87, and an input device 88.

The CPU 81 functions as the heating amount detecting means 46, the writing means 47, and the first control means 49 shown in FIG.

The RAM 82 has an address 83 which serves as the storage means 48 shown in FIG.

ROM86 stores the control program.

In the ROM 87, the heating amount data and the stirring amount data for each time, which are used in advance when performing a standard kneading operation, are sequentially stored at regular time intervals.

The input device 88 is for operating the stirrer 5 and the gas pot 25, and selecting a work mode.

Next, the connection between the control device 80 and other devices will be described.

The heating output of the gas kettle 25 is adjusted by moving the piston of the solenoid 76 in and out of the valve 71 to adjust the opening amount of the main valve 74. The adjustment of the solenoid 76 is performed by adjusting the applied current. The CPU 81 and the solenoid 76 are connected via a D / A converter 90 and an amplifier 91.

The CPU 81 and the inverter type drive control device 89 are connected. When a control signal is input from the CPU, the drive control device 89 internally converts the control signal into a DC voltage signal, and drives the motor 11 at a rotation speed set according to the height of this voltage.

Next, the operation of the bean kneading machine 70 of the embodiment will be described (see FIGS. 6 to 8).

First, a certain amount of red beans (or raw bean paste, bleached bean paste), sugar and water is set in the bowl pot 3. Then turn on the power. Then, the CPU 81 calls the program from the ROM 86 and the initial set 100 is performed. After that, an external display device (not shown) displays a mode selection screen and prompts the operator to select a mode (steps 101 to 102).

At the start of work, the mode selection switch 88c of the input device 88
First, the operator selects the program mode 103 for teaching. Then, while the operator is manually operating the kneading operation as in the past, for example, as shown in FIG. 12 and FIG. 13, the heating amount and the stirring amount are adjusted according to the elapsed time, as described below. Good boiling is done manually.

At this time, the opening adjustment of the valve 71, that is, the output of the heating device,
By operating the gas kettle switch 88b of the input device 88 to output a heating signal from the CPU 81 to the solenoid 76. The rotation of the agitator 5 is performed by operating the agitator switch 88a to output a control signal from the CPU 81 to the drive control device 89.

When the program mode for teaching is selected and the operation of the kneading machine is started, the CPU 81 executes the teaching process shown in FIG. 7 by, for example, a timer interrupt process that enters every 10 seconds. The heating signal at that time (the heating amount data set in the input device 88 by the gas kettle switch 88b) is read, and in step 112, R
Store in the teaching program area of AM82 in order of time. Next, in step 113, the CPU 81 reads the stirring signal (the stirring amount data set in the input device 88 by the stirring device switch 88a) at that time, and in step 114, R
Store in the teaching program area of AM82 in order of time. By repeating such processing every 10 seconds, for example, the CPU 81 causes the RAM 82 to sequentially store the data of the heating amount and the stirring amount at that time. During this time, the operator operates the kneading machine while manually operating the gas kettle switch 88b and the agitator switch 88a of the input device,
The amount of heating and the amount of stirring are adjusted as shown in FIG. 12 and FIG. 13 according to the elapsed time to perform good kneading. For this reason,
The data of the heating amount and the stirring amount at the time of the good kneading work performed by the operator are all sequentially stored in the RAM 82.

In this embodiment, the heating signal and the stirring signal are sequentially written to the RAM 82 based on the operation of each switch of the input device 88, but the writing of each signal is collectively performed after the work is completed. You can also do it. Furthermore, the heating signal is
It can be obtained by detecting the state of the solenoid 76 or the gas flow rate. Similarly, the stirring signal can also be obtained by detecting the rotation of the motor 11.

Next, the automatic mode 104 will be described.

First, a predetermined amount of red beans, sugar and water (the same as in the program mode) is set in the bowl pot 3. Then, the mode selection switch 88c of the input device 88 is operated to select the automatic mode 104, and the gas tank is ignited to start the automatic operation. Then, the subroutine 120 of FIG. 8 is called.

In this subroutine 120, first in step 121, the CPU 81
Reads the heating data written at the time of teaching from the RAM 82 in chronological order, and in step 122 controls the solenoid 76 based on the heating data to adjust the opening of the valve 71 and adjust the heating amount. Further, in step 123, similarly, the stirring data is read from the RAM 82 in order of time, and in step 124
Then, the motor 11 is controlled based on the stirring data, and the rotation of the stirrer 5 is drive-controlled. Thus steps 121-1
24 is repeated and the bean kneader is automatically operated, so that the bean kneading work stored in the above-mentioned teaching program mode is reproduced as it is, and the heating amount and the stirring amount as shown in FIG. 12 and FIG. Is adjusted, the bean paste is satisfactorily performed in the same manner as that performed by a skilled operator, and a delicious bean paste is automatically produced.

The reading operation of each signal is performed by the clock generator at the same time as the program sub 110. As a result, the operator's kneading work is reproduced.

In this embodiment, since the ROM 87 stores the patterns of the heating signal and the stirring signal corresponding to the standard bean kneading operation, the automatic sub-120 should read these signals appropriately to operate the bean kneader 70. You can Particularly, since the timing of stirring does not significantly affect the properties of the bean jam, the stirring signal stored in the ROM 87 can be used.

In addition, when the operator simply performs the work manually, the manual mode 105 is selected. And the manual subroutine 150
Executes so that CPU81 is not activated.

When the work is finished, the key is turned off 107.

Second Embodiment FIG. 9 shows the bean kneading machine 160 of this embodiment. The same parts as those in the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted.

Reference numeral 161 in the figure is a buzzer, which emits a sound based on an operation signal from the CPU 81.

Reference numeral 163 is a contact-type temperature detector, which uses a thermistor. The temperature detector 163 detects the temperature of the bowl 3 and inputs a digital signal to the CPU 81.

The input device 88 is newly provided with a correction signal setting switch 88d and a stop switch 88e. Correction signal setting switch 88d
Is a preparation step (before heating; the temperature of the bowl pan 3 is room temperature) in the standard bean kneading work (first work).
Compensation for the shortening time of the standard bean kneading work for the temperature difference between the bowl 3 and the ball pan 3 at the preparation stage of the actual bean kneading work (the temperature of the ball pan 3 may be raised) It is for writing as a signal to the address 167 (correction signal storage means) of the RAM 82. If the temperature of the ball pot 3 is raised in the actual kneading work, a part of the heat is given to the contents, and the amount of heat wasted to raise the temperature of the ball pot 3 is reduced. In view of this, this shortening time is set according to the amount of decrease in the total amount of heat to be given by the heating means.

According to a study by the present inventor, a standard bean kneading work was performed from the bowl pan 3 cooled to room temperature (15 ° C.) according to the time chart shown in FIGS. A suitable bean paste was obtained in minutes. By the way, by this bean paste work, the first 22kg of ingredients (red beans: sugar: water = 10: 7: 5)
Had reduced its total weight by 4 kg. This weight reduction is due to the evaporation of water. Immediately after the completion of this work, the next mixing work was carried out with the same amount and the same amount of raw material along the time chart shown in Figs. At that time, a suitable bean paste was obtained at 52 minutes and 39 seconds. By the way, the total weight of raw materials was reduced by 4 kg. In the subsequent work, the temperature of the bowl pan 3 before heating was 65 ° C.

Therefore, in this case, the shortening of the working time of 1 minute 21 seconds is the content of the correction signal corresponding to the temperature difference of the bowl 3 of 65 ° C-15 ° C = 50 ° C.

When using the kneading machine 70, it is preferable to maximize the amount of heating at first.

In this way, the correction signal corresponding to the temperature difference is obtained, and the correction signal setting switch 88d stores the table in the address 167 of the RAM 82. Of course, when changing the quality and quantity of raw materials, a new temperature difference-correction signal table is prepared accordingly.

When the stop switch 88e is turned on, all the heating signals read from the address 83 of the RAM 82 are corrected to heating signals corresponding to the heating amount 0.

Next, the operation of the kneading machine 160 of this embodiment will be described.

The basic operation is the same as that of the kneading machine of the previous embodiment, but in this kneading machine 160, the program mode 103 (6th
10) is selected, the subroutine 170 of FIG. 10 is executed. In this program sub 170, the temperature of the bowl pan 3 immediately before starting the work is read by the temperature detector 163.
1, a predetermined address 165 of the RAM 82 as the reference temperature signal t
172 is written to (reference temperature signal storage means). The subsequent steps 111 to 115 are the same as in FIG.

When the automatic mode 104 is selected, the automatic sub 120 shown in FIG. 8 is executed and the subroutine 180 shown in FIG. 11 is executed. In the correction sub-180, first, the temperature of the bowl pan 3 immediately before the start of work is detected by the temperature detector 163 and is read into the CPU 81 as a temperature signal T 181. Then, the reference temperature signal t stored in the address 165 of the RAM 82 is read 182, and the temperature signal T and the reference temperature signal t are compared 183. Then, based on the difference, the correction signal stored in the address 167 of the RAM 82 is read 184 and the end time of the kneading operation corresponding to the correction signal is determined 185. Then, the current work time of the beaker 161 is compared with the correction end time determined above 186, and when the current work time reaches the correction end time, an operation signal is output to the buzzer 161.
Sounds this to call the operator's attention 187.

When the buzzer sounds, the operator turns on the stop switch 88e. Then, all the heating signals read by the automatic sub (FIG. 8) are corrected to heating signals corresponding to the heating amount 0. Therefore, the heating is stopped.

By doing so, when the bean kneading machine 160 is automatically operated, the total amount of heat applied to the contents can be constantly kept constant. As a result, a more uniform bean paste can be manufactured.

In this embodiment, in order to stop the heating, the stop switch 88e is turned on to correct the heating signal read from the RAM 82 to the one corresponding to the heating amount 0.
25 may be stopped manually.

A lamp or the like can be used instead of or in combination with the buzzer 161.

Further, although the reference temperature signal is detected immediately before the work is started, it may be detected after the work is started. In this case,
Steps after reading the temperature signal T (step 181) are shifted after the start of the kneading operation.

Also, in the standard kneading work and the actual kneading work,
Since the conditions of the contents themselves may differ, the reference temperature signal and the temperature signal can be detected from the contents.

It is also possible to detect the reference temperature signal and the temperature signal from the fire bed (gas kettle 25).

Needless to say, the heating time can be adjusted more accurately by setting the correction signal based on the reference temperature signal and / or the temperature signal detected from two or more locations and / or detected at two or more timings.

Further, in the above embodiment, the buzzer is sounded based on the correction signal, but if the heating signal read from the RAM 82 is directly corrected to the one corresponding to the heating amount 0 based on the correction signal, it is possible to correspond to complete automation. . In this case, it is not necessary to correct all the heating signals to those corresponding to the heating amount 0,
For example, the heating amount can be corrected so as to be reduced by 50%.

The control device 80 has been described above by taking the digital control device as an example, but of course, this may be analog control.

<Effects of the Invention> As described above, the cooker of the present invention is a cooker comprising a pan, a heating means for the pan, and a stirring means for stirring the contents of the pan. Amount detection means for detecting a heating signal and outputting a heating signal, a heating signal writing means for writing the heating signal to the storage means, a heating signal is read from the storage means, and an output of the heating means is detected based on the heating signal. First control means that is the same as when it is detected by the means,
It is characterized by including. According to this, in the cooking operation performed by the operator, it is possible to reproduce the heating condition which has a particularly large influence on the product, so that the product of uniform quality can be constantly produced.

Further, if the timing of stirring is decided, the heating adjustment is automatically performed, so that the operator does not have to always come to the simmer. Therefore, the running cost of the cooker can be reduced.

Furthermore, if you set the reference temperature of the pot etc. and compare the reference temperature with the actual temperature during each cooking operation, you can correct the total heating amount according to the condition of each operation, A more uniform quality product is obtained.
