Hereinafter, the present invention will be described with reference to the accompanying drawings.

The system shown in Figure 1 is a system in which the present invention is used. In general, the cooker control device 100, igniter, electronic valve, thermal coupler, thermistor, burner.

The cooker control device 100 uses a thermocouple, an igniter, and an electric stool in relation to the steaming of bread. In relation to cooking, the thermistor is further used, and a specific method of use thereof will be described later.

And a timer (not shown) is built in. When cooking bread, unlike cooking, the fire is fired regardless of the temperature of the pot, and when the predetermined bread steaming time elapses, fire extinguishing takes place. The steaming time is checked using the timer.

The bread steaming time is not variable according to the user operation, it is fixed to one. This is to be suitable for military use.

The steaming time varies depending on the type and quantity of military bread, the size and weight of the pot, and the material.

For example, it is a conventional military bread for 50 people, and gas consumption is LNG-29,000 kcal / h, LPG-2,417 kcal / h, and W700 x D777 x H1,337 (W: horizontal, D: vertical, H: height) In the case of), approximately 13 minutes are preferred.

The thermal couple is used to detect the ignition and is installed around the burner of the cooker. When the output voltage is more than a predetermined voltage, it is determined that the burner is ignited, and the predetermined voltage is about 8 to 16 (mV).

The thermistor is used to detect the temperature of the pot and is installed at the bottom of the pot. When the output voltage thereof is equal to or higher than a predetermined voltage, that is, when the temperature reaches the normal temperature, it is determined that cooking is completed and the steam is passed to the steaming, and the predetermined voltage is about 1.5 to 4.7 (V).

The cooking control operation of such a system is as follows.

First, when the cooking key signal is input from the outside according to the user's selection, the cooking device control device 100 turns on the igniter and the electronic valve.

Then, when the output voltage of the thermal couple is equal to or higher than a predetermined voltage, that is, when ignited, the electronic valve is kept on. On the other hand, when the output voltage of the thermal couple is smaller than the predetermined voltage, that is, when the ignition is not performed, the electronic valve is turned off.

If ignition occurs, the temperature of the pot is detected. And it digests according to the detected result. For example, when the output voltage of the thermistor installed under the pot is equal to or higher than a predetermined voltage, that is, when the temperature of the pot reaches a normal temperature, the electronic valve is turned off to be extinguished.

When you're digested, wait until the rice is steamed and let the outside know you're done. That is, after the electronic valve is turned off, when the predetermined moxibustion time elapses, the predetermined lamp is turned on to notify the outside that cooking is completed.

Next, the bread steaming control operation of the system is as follows.

First, when the bread steaming key signal is input according to a user's selection, the cooking apparatus control device 100 turns on the igniter and the electronic valve.

And when the output voltage of a thermocouple is more than predetermined voltage, it determines with ignition. Then, the electron valve is kept on. On the other hand, when the output voltage of the thermal couple is smaller than the predetermined voltage, it is determined that no ignition has occurred. Then, the electron valve is turned off.

On the other hand, when the ignition is performed, the electronic valve is turned off, and then the electronic valve is turned off when the preset steaming time elapses.

When the electronic valve is turned off, the predetermined lamp is turned on to inform the outside that the steaming is completed.

The cooker control method illustrated in FIG. 4 is an example of the cooker control method according to the present invention.

Referring to FIG. 4, a method of controlling the cooking operation and the steaming operation is as follows.

First, the cooking operation is controlled.

First, a key signal is received from the outside (S400).

The key signal may be input through an operation panel according to a user selection.

When the key signal input in step S400 is a cooking key signal (S401), the igniter is driven and the electronic valve is turned on (S402). Thus, the burner can be ignited.

Next, it is determined whether to ignite.

Specifically, when the output voltage of the thermal couple used to detect whether the ignition is a predetermined voltage or more, it is determined that the ignition. Thus, the electron valve is kept on.

On the other hand, when the output voltage of the thermal couple is smaller than the predetermined voltage, it is determined that the ignition is not performed (S403). Then, the electronic valve is turned off so that no gas is supplied to the burner (S404).

Next, if it is determined that the ignition is in step S403, in order to detect the temperature of the pot, the output voltage of the thermistor installed around the pot is read.

When the output voltage of the thermistor is equal to or greater than a predetermined voltage (S405), that is, when the temperature of the pot reaches a predetermined normal temperature, the electronic valve is turned off (S406) to allow the burner to be extinguished.

When the digestion is performed in this way, the predetermined moxibustion waits for a time, and then informs the outside that cooking is completed.

That is, after the electronic valve is turned off according to the step S406, when the predetermined moxibustion time elapses (S407), the lamp is turned on (S408) to inform the outside that cooking is completed.

The following is a method of controlling the steaming operation.

When the key signal received in step S400 is a bread key signal (S409), the igniter is driven and the electronic valve is turned on (S410). This allows the burner to ignite.

Next, it is determined whether to ignite.

Specifically, when the output voltage of the thermal couple used to detect whether the ignition is a predetermined voltage or more, it is determined that the ignition. Thus, the electron valve is kept on.

On the other hand, when the output voltage of the thermal couple is smaller than the predetermined voltage, it is determined that the ignition is not performed (S411). Then, the electronic valve is turned off so that no gas is supplied to the burner (S404).

When the ignition is performed according to the step (S411), if a predetermined bread steaming time has elapsed since the electronic valve is turned on (S412), by turning off the electronic valve (S413), the burner can be digested.

When the electronic valve is turned off according to the step S413, the lamp is turned on (S414) to inform the outside that the bread steaming is completed.
