Description

TECHNICAL FIELD The present invention relates to a jar rice cooker capable of executing a program for an assembly process.

2. Description of the Related Art In a conventional jar rice cooker equipped with a microprocessor, the microprocessor is reset when the power is turned on, so a normal program and a program for the assembly process can be executed by the first input after the reset is released. There was something to execute selectively.

Problems to be Solved by the Invention However, in recent years, it has become mainstream to provide a jar rice cooker with a clock function and guarantee a clock function operation by a backup battery even when the power is turned off. Since there is no reset even when the power is turned on, the conventional configuration has a problem that the program for the assembly process cannot be switched.

The present invention solves such a conventional problem, and in a very basic state in which no menu is selected and no reservation time is set, the program is switched by discriminating a predetermined key combination input. It is intended to provide a jar rice cooker that can be executed and easily inspected during assembly.

Means for Solving the Problems In order to solve the above problems, the jar rice cooker of the present invention is
Key combination discriminating means for discriminating that a predetermined key combination has been input without menu selection and reservation time setting, and program switching means for switching programs by the output of the key combination discriminating means Is.

Operation With the jar rice cooker of the present invention having the above-described configuration, it is possible to switch a program by executing a predetermined key combination in a specific state.

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 jar rice cooker according to an embodiment of the present invention, in which 1 is a key input section for a reserved time calling key 10, a minute digit key 11, a reservation completion key 12, and a menu select key 13. The output is input to the menu selection unit 2, the reserved time setting unit 3, and the key combination determination unit 4. The menu selection means 2 is
The menu is changed each time the menu select key 13 is pressed, and a corresponding program, for example, a white rice menu program 5a or a cooked rice menu program 5b is changed.
Is selected from the storage means 5 and transmitted to the program switching means 6. The reservation time setting means 3 increases or decreases the reservation time with the reservation time call key 10, the minute digit key and the hour digit key (not shown), and sets the reservation time with the reservation completion key 12. The key combination discriminating means 4 receives the output of the key input section 1 as an input, and before the menu select key 13 and the reservation time calling key 10 are pressed (that is, the menu select and the reservation time are not set). , When the reservation time call key 10, the minute digit key 11 and the reservation completion key 12 are pressed simultaneously, an output is generated and transmitted to the program switching means 6. The program switching means 6 selects the assembly process program 5c from the storage means 5 only when the output is transmitted from the key combination determination means 4. As an example of the assembly process program 5C, a reserved time call key 10
When the minute digit key 11 and the reservation completion key 12 are released, the heating operation (rice cooking operation) is immediately started, and the rice cooking operation is stopped when the heated pan reaches a predetermined temperature (not shown). There are various programs. If this process program 5C is started in an empty pan state in which rice and water as a load are not put, the temperature rises and the heating operation stops in a relatively short time (several minutes). If the heating operation stops within a few minutes, it can be seen that the temperature sensor and the control circuits such as the microcomputer have operated correctly. This is a demo program for process inspection.

Next, the operation of this embodiment will be described. FIG. 2 is a flow chart showing the main part of the processing flow of this embodiment. Reference numeral 20 is a step for judging whether or not the menu select key 13 has been pressed. When there is a key input, the menu is determined in step 21, and a flag is set in step 22 to indicate that the menu select has been performed. Reference numeral 23 is a step for judging whether or not the reservation time calling key is pressed. If there is a key input, a reservation time setting process is performed in step 24 and a flag is set in step 25. On the other hand, if the reserved time call key 10 is not pressed, it is determined in step 26 based on the flag whether menu selection or reservation time setting has already been made, and if the flag is not set (that is, menu select (If the reserved time is not set), it is confirmed in step 27 whether or not there is a predetermined combination of key inputs. If a predetermined key input has been made, the assembly process program 5C is executed. When the flag is set in step 26 and when there is no predetermined key input in step 27, the process proceeds to step 28, and the above loop is repeated until a rice cooking start key (omitted in FIG. 1) is pressed. .

As described above, in one embodiment of the present invention, the program 5C for the assembling process can be executed by giving a predetermined combination of key inputs when neither menu selection nor reservation time setting has been made. It is very useful because it can.

EFFECTS OF THE INVENTION As described above, according to the present invention, it is possible to switch programs by giving a predetermined combination of key inputs when neither menu selection nor reservation time setting has been made. In addition, the program can be surely switched, and as a result, the process of assembling the product can be simplified and a great effect can be brought about in the inspection of the product.
