Description

TECHNICAL FIELD The present invention relates to a control device for a cooking device used in a general household.

2. Description of the Related Art In recent years, control of a cooking device is complicated and is a sequence control for a long time. Therefore, a microcomputer has been used for the control, and as shown in the control flowchart shown in FIG. The control processes of ~ 208 are executed at regular intervals. When it is desired to check the control operation of the microcomputer or the operation of the control element to be controlled here, for example, the fourth step of FIG.
When confirming the movement of 207, it was started normally, waited near the end time of the third control step of step 205, then the operation was started to be checked, and step 207 was checked. Further, the execution time is increased by several hundred times, and the process is advanced to near the end of the third control step of step 205, then returned to the normal execution time, and the fourth step of step 207 is checked.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above method, when executing the check at a normal execution time for checking, it is necessary to wait until the control step to be checked is reached, and a great amount of time is spent for checking. It was In addition, the method of accelerating the execution time is also set to a very early execution time in order to reach the check point quickly, so it is not possible to return to the normal execution time at the exact position, it is a few minutes too early, or the worst. In the case of, I went too far and had to start over again.

In view of such problems, an object of the present invention is to obtain a control device for a cooker having a check system that can be executed quickly, easily and accurately from a control process to be checked.

Means for Solving the Problems In order to achieve the above object, the present invention is provided with a test means capable of arbitrarily selecting and setting from which position in a predetermined execution order the execution is started. It is a thing.

With the above configuration, the control device for a cooking device according to the present invention, when the operation check of each control step or the operation check of various control elements such as a relay, a triac, and a solenoid to be controlled is performed, the control element When the process in which is operated is set to the process which the control element control means first starts to execute by the test means and is started, the process starts from that step, so that the check can be easily performed.

Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram of a control device for a bread maker according to an embodiment of the present invention, in which 1 is an AC power source, 2 is a motor for kneading bread ingredients, and 3 is yeast in the bread ingredients. Solenoid for turning on solenoid 4 is a diode bridge for producing a DC power source for driving solenoid 3. 5 is a heater for baking bread dough,
Energization of the heater 5 is controlled by a relay 6. 7,8
Are triacs, these triacs 7,8 are motors
2, Energize the solenoid 3. 9 is the triac
Timing data for controlling the sequence control of 7, 8 and the relay 6 is recorded in the control process storing means, and the control process storing means 9 includes 1A to 3C as shown in FIG.
There are 9 types.

Reference numeral 10 denotes an execution order storage means group that stores the order in which several steps to be used are selected from the control step storage means 9 and executed. The execution order storage means group 10 is as shown in FIG. , Bread, French bread, soft bread, etc. There are three types from A to C according to the menu. And in this embodiment,
The execution order storage means A is stored so that the three types of control process storage means 1A, 2A, 3A are executed in this order. Similarly, the execution order storage means B is stored in the control process storage means 1B, 2A.
B, 3B are stored so as to be executed in this order, and the execution order storage means C further includes control process storage means 1C, 2
It is stored so that three types of C and 3C are executed in this order. Reference numeral 11 is a key input means composed of four kinds of key switches SW1 to SW4, and SW1 is a control element control means 12 which will be described later.
, SW2 is a switch for stopping, SW3 is a switch for selecting three menus of execution order storing means A to C, and SW4 is a time for starting control by the first control process storing means by the execution order storing means. It is a timer setting switch for.

Reference numeral 12 is a control element control means for sequentially reading the control process storage means in accordance with the order stored in the execution order storage means and controlling and executing the triacs 7, 8 and the relay 6. Reference numeral 13 is a test means for setting a test mode when SW2 and SW3 are simultaneously pressed by the key input means 11 and setting which step of the process order stored in the execution order storage means starts execution.

Next, the operation of the control device for the bread maker configured as described above will be described with reference to the flowcharts shown in FIGS. 2 and 3.

First, in step 100, it is determined whether SW2 and SW3 are pressed at the same time. If they are not pressed at the same time, the normal mode is set, and the process proceeds to the next step 101. In step 101, it is determined whether or not the switch SW4 for setting the timer is pressed. If it is pressed, the timer is set in step 102, and the process proceeds to the next step 103. On the other hand, if SW4 is not pressed in step 101, the process proceeds to step 103. In step 103, if the switch for selecting A, B, C of the execution order storing means 10 of FIG. 1 which is three kinds of menus is pressed, the menu is changed in step 104 and the menu number M is selected. Put A, B or C in. If SW3 is not pressed, the process proceeds to step 105. Here, the menu number is assumed to have A as an initial value.

In step 105, if the switch SW1 for starting is pressed, the control starts and the next step 10
6, the process number K for counting the execution order stored in the execution order storage means A, B, C of FIG.
Set to. If SW2 and SW3 are pressed at the same time in step 100, the test mode is entered. If SW3 is pressed in step 108, the menu number is changed in step 109. If not pressed, the process proceeds to the next step 110. . step 1
At 10, in the normal mode, see the input state of SW4 which is the timer setting switch. On the other hand, in step 110, which is the test mode, when the switch is pressed, step 1
At step 11, change the value of process number K and set it. If SW4 is not pressed, the process proceeds to step 112. Then, when SW1 is pressed in this step 112, the normal mode is set, and the routine proceeds to step 107. In this case, if the switch is not pressed, the process returns to step 108 and is repeated until SW1 is pressed.

In step 107, the menu A is designated by the menu number M.
Becomes M = A, the process proceeds to the subroutine of step 113,
Further, the menu B becomes M = B, and the process proceeds to the subroutine of step 114, and the menu C becomes M = C, and the process proceeds to the subroutine of step 115. When returning from each subroutine, the process returns to the first step 100.

Next, the case where M = A at step 107 and the routine proceeds to the subroutine of step 113 will be described with reference to the flowchart of FIG. First, if the timer is set in step 116, it waits until the timer ends in steps 117 and 118, and when the timer ends, the process proceeds to the next step 119. If the timer is not set in step 116, the process similarly proceeds to step 119. At step 119, the process proceeds to any one of steps 120, 121, 122 and 123 depending on the value of the process number K. Step 120 is one of the control process storage means 9 shown in FIG.
Corresponding to A, the content of the process is a process of controlling the motor 2 for kneading the bread ingredients. Step 121 corresponds to 2A of the control step storage means 9, and the content of the step is a step of controlling the solenoid 3 for introducing yeast. Step 122 corresponds to 3A, and the process content is a process of controlling the heater 5 for baking the bread dough. In the normal mode, since K = 0 at step 119 at first, always proceed to the next steps 120 and 124, and knead 2
Do it for 0 minutes. Then, in step 125, the process number K is incremented by 1, and the process returns to step 119.

Similarly, when K = 1, steps 121 and 126 are performed.
Go to the yeast loading process, and when K = 2, step 12
Go to 2,127 firing process. When K = 3, the routine proceeds to step 123, where all controls are stopped and the subroutine is finished.

Here, when this menu A subroutine is set to the test mode and the process number K is executed with a value of 1 or 2 instead of 0, when K = 1 from the beginning, the yeast feeding process 121 starts, and when K = 2. Starts from the baking step 122 and is thereafter executed until the end step to complete the bread making.

The subroutine of steps 114 and 115 is step 113.
Only the process contents in the subroutine of menu A are different, and the description thereof will be omitted.

EFFECTS OF THE INVENTION As is clear from the description of the above embodiments, according to the present invention, since the test means capable of starting each control process unit is provided, only once during the long time from the kneading of bread ingredients to the end. Even when checking the operating state of the solenoid for yeast movement that does not move, it is possible to start from the yeast feeding process, so there is no waiting time compared to when starting from the kneading process and checking, You can check in a short time.
Further, as compared with the method of increasing the execution speed and advancing to the point before the check point, the control time can be accurately checked because the control can be started accurately from that point.
