Description

Demo mode processing method of electric rice cooker.

The present invention relates to a demonstration mode processing method of the electric insulation rice cooker, and more particularly, to a demo mode processing method of the electric insulation rice cooker to check the respective process state of the electric insulation rice cooker by a simple operation.

As is well known, the electric thermal rice cooker is provided with an operation environment for each process according to the contents of the bar, which is first started after the cooking operation of each cooking key after the state where the inner pot is settled. The general electric rice cooker, as shown in the block diagram shown in Figure 1, a key input unit 12 consisting of keys for setting various operating environment of the electric rice cooker having a cooking function and the heat insulating function, and the bottom of the electric rice cooker and The thermostat rice cooker is installed on the body and the lid and detects a temperature generated by various heaters by a sensor, and an electric heat cooker based on a temperature value detected by a key input and a temperature sensor of the key input unit 12. Microprocessor 10 for controlling the operation of, and is installed on the bottom and lid and the body of the electric thermal cooker and operates under the control of the microprocessor 10 to control the operation of the heater to heat the inside of the electric thermal cooker It consists of the heater drive part 16 and the display part 18 which displays the operation state of the said electric thermal rice cooker.

Referring to the electric insulation rice cooker in more detail by referring to FIG. 3, the microprocessor 10 built in the electric insulation rice cooker maintains the standby state when the operation power is supplied (S301), and determines whether various cooking modes are set by key input. It determines (S302). As a result of the determination, if the cooking mode (refers to Jinbap, Donbap, Ordinary rice, Mixed grain rice, brown rice, etc.) is not set, the standby state is continuously maintained (S301), and when the cooking mode is set, cooking of the heater driving unit 16 is performed. The heater, the lid heater and the body heater are operated to execute the set cooking mode (S303). That is, it is determined whether cooking is complete by controlling the operation time or operating temperature of the cooking heater of the heater driving unit 16, the lid heater, and the body heater according to each cooking mode to perform the cooking mode (S304).

If the cooking operation is not terminated, the microprocessor 10 continues to execute the cooking mode (S303). When the operation of the set cooking mode is terminated, the cooking heater and the lid heater of the heater driving unit 16 are finished. And blocking the operation power supplied to the body heater (S305), and performing an insulating function, and detecting an internal temperature of the electric thermal cooker (S306) detected by the cooking temperature sensor of the sensing unit 14 (for example, 75). It is determined whether it is lower than (° C.) (S307). As a result, when the internal temperature of the electric insulation rice cooker is higher than a predetermined temperature (eg 75 ° C.), the internal temperature of the electric insulation rice cooker is detected again (S306), and the internal temperature of the electric insulation rice cooker is a constant temperature (eg 75 ° C.). If lower than), the various heaters of the heater driving unit 16 are operated (S308) to increase the internal temperature of the electric thermal cooker. Therefore, since the internal temperature of the electric rice cooker maintains a certain temperature (eg 75 ℃), it is possible to heat the rice stored inside.

Referring to the cooking process of the electric insulation rice cooker in more detail by FIG. 2, first, when the operation mode of the electric insulation rice cooker is set to the cooking mode, supply operation power to the cooking heater and lid heater and body heater of the heater driving unit 16; To increase the internal temperature while absorbing water into the rice inside (T1) for a certain period of time (refer to about 10 to 12 minutes) to maintain the internal temperature Increase to). When the absorption step (T1) is completed to allow the water to be absorbed into the inside of the rice is completed by performing the first heating step (T2) to determine the cooking amount while raising the interior to a predetermined temperature (for example, 75 ℃) rice inside the rice Determine the amount of. That is, when it takes about 2 minutes to increase the internal temperature of the electric rice cooker to 75 ° C, it is determined as the amount of cooking for one person and is supplied to each heater in the second heating step T3 and the boiling maintenance step T4. The amount of heat supplied to the heater is adjusted to 80%, and if it takes about 3 minutes, it is determined as the amount of cooking for 2 servings and the amount of heat supplied to each heater in the second heating step (T3) and boiling maintenance step (T4) is adjusted to 85%. .

When it takes about 4 minutes, it is determined as the cooking quantity of 3 servings, and the amount of heat supplied to each heater is adjusted to 90% in the second heating step T3 and the boiling maintenance step T4. The amount of heat supplied to each heater is adjusted to 95% in the second heating step (T3) and the boiling point holding step (T4), and if it takes about 6 minutes, it is determined as the cooking amount for 5 people. By adjusting the amount of heat supplied to each heater in the second heating step (T3) and boiling maintenance step (T4) to 100%, in the second heating step (T3) to raise the internal temperature to a certain temperature (for example, 102 ℃) . Subsequently, the second heating step (T3) is extended to heat the inside to perform a boiling maintenance step (T4) for heating the inside so that the internal temperature rises to the cooking temperature (for example, 125 ℃). After each process is completed, the cooking process is completed and the heating process is completed while the steaming process (T5) is performed to heat the cooked rice to a predetermined temperature (115 ° C.) for a predetermined time (about 12 minutes). do.

As in other household appliances, when the electric rice cooker is produced or sold, it performs demo mode to check the operation status of the electric rice cooker, which operates a specific key (key for setting the demo mode). After that, there is a hassle to supply the driving power of the electric rice cooker.

The present invention has been made in order to eliminate the problems as described above, so that a simple operation, that is, to perform a demo mode for notifying each operation state of the electric insulation rice cooker even when the main power supply of the electric insulation rice cooker The purpose is to provide a demonstration mode processing method of the electric rice cooker.

The present invention for achieving this object is the step of checking the input state of the main power supply, the step of checking whether a specific key flag for setting the demo mode when the main power supply, and the power failure mode if the specific key flag is set It is characterized in that it performs the step of determining whether, and when the power supply normally set the demo mode flag and outputting a message informing each process state of the electric rice cooker at a predetermined time (T) interval.

The configuration of the electric insulation rice cooker for explaining an embodiment of the present invention is a key input unit for inputting cooking data as in the conventional electric rice cooker, a sensing unit having various sensors, a heater driving unit for heating each unit, a display unit, etc. It consists of.

Figure 4 is a flow chart illustrating an operating state according to an embodiment of the electric thermal cooker for achieving the object of the present invention, the step of checking the input state of the main power supply, and a specific for setting the demo mode when the main power supply Checking whether the key flag is set, determining if the key flag is set, whether the power failure mode is set, and setting a demo mode flag when the power is normally supplied and displaying a message indicating each process state of the electric rice cooker for a predetermined time ( T) outputting at intervals.

Looking at the process of performing the demonstration mode of the electric rice cooker (S1), first, the microprocessor checks the main power (S2) to check whether a key for supplying the main power is input (S3). When the main power is not supplied, the power failure mode that maintains the standby state is maintained (S4), and when a specific key for supplying the main power is input, a specific key for performing the demo mode (here, the specific key is formed in the key input unit). It is checked whether the flag of one of the keys or a key separately configured to set the demo mode is set (S5). If the flag of the specific key is not set, the general process of sequentially performing the absorption process, the heating process, the boiling maintenance process, the steaming process, and the warming process is performed as in the conventional electric rice cooker (S6).

If the flag of the specific key is set, it is determined whether the electric rice cooker is in the blackout mode (S7). In the blackout mode, regardless of the cooking amount or cooking method (usually rice, rice, jinbab, etc.), the electric rice cooker is heated to 130 ° C. as a conventional electric rice cooker to perform a heating process and a boiling process. Subsequently, an electrostatic treatment mode for performing the moxibustion process and the thermal insulation process is performed (S8). However, if the power failure mode is set, the demo mode flag is set (S9) and the demo mode is performed (S10). In more detail, first, the display time is counted while outputting a message indicating the absorption process, which is the first process of the electric rice cooker, to the display unit (S11), and the predetermined time T elapses (S12; for example, 5 seconds). When the time) is displayed, the display time is counted while outputting a message indicating the heating process, which is the next process, to the display unit (S13). As a result, after the predetermined time T has elapsed, a message indicating the boiling maintenance process and the moxibustion process is displayed for a predetermined time, and finally, a message indicating the warming process is output to the display unit for a predetermined time (S15) (S16). The demo mode is terminated while the demo mode flag is cleared (S17).

The present invention can perform a demo mode for notifying each operation state of the electric thermal cooker by a simple operation, that is, even a simple key operation even when the main power supply of the electric thermal cooker is supplied.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
