It is made up.

Referring to the effects of the present invention configured as described above are as follows.

First, when the power is applied to the electronic cooker, the microcomputer 100 of the electronic cooker goes to the timer function performing step 201, and is initially reset. Then, as shown in FIG. When the day, day, and time keys are set by pressing, the microcomputer 100 receives a key signal according to the pressed state of the keyboard unit 110 and operates the timer 101 at the current month, day, day, and time. Data for the display is output to the display driver 140 and displayed on the display panel 150.

In this way, the user displays the month, day, day of the week, and time on the display panel 150 of the electronic cooker through the timer function performing step 201. When the microcomputer 100 goes to the menu display input step 202 of the menu selection display step 240 to determine whether the menu display is pressed, and the menu display signal of the keyboard unit 110 is inputted, The microcomputer 100 controls the signal and outputs the controlled signal to the memory 130 so that the menu type and menu information stored in the memory 130 are transferred to the menu display step 203 through the microcomputer 100. The display driving unit 140 is operated to display various kinds of menus with the display panel l50.

Subsequently, when the user does not have a menu to cook in the menu display step 203 and enters a progress key to view the next menu through the keyboard unit 110, the microcomputer 100 goes to the progress key input determination step 204. After determining whether the advance key signal is input, if the advance key is input, the microcomputer 100 controls the memory 130 to display data on the next type of menu stored in the memory 130 through the microcomputer 100. Go to the display step 203 to operate the display driver 140 to display the next menu on the display panel 150.

Subsequently, when the user selects one of the menus displayed on the display panel 150 through the keyboard unit 110, the microcomputer 100 controls the selected key signal and goes to the menu selection determination step 210 to complete the menu selection. If the user does not press the progress key in the progress key input determination step 204, the menu selection completion step 210 goes to determine whether the user's menu selection is completed.

On the other hand, if the menu display is not pressed in the menu display input step 202, the microcomputer 100 goes to the menu encouragement key input step 206 and determines whether the menu encouragement key is pressed from the keyboard unit 110. In this case, when the user presses the 몌 New Encouragement Key, the microcomputer 100 goes to the season discrimination step 207 and determines the current month, day, day, and time that are being counted by the timer 101 to determine the season or the memory from the memory l30. After reading the menu suitable for each meal, go to the menu display step 208 and display the menu through the display panel l50. Then, go to the menu selection completion judgment step 210 of the menu selection and the preparation display step 250. In this case, if the user does not select a menu, the menu display input step 202 is repeatedly performed.

Subsequently, if the menu is selected in the menu selection completion step 210, the user inputs the number of people to eat food through the keyboard unit 110, and the microcomputer 100 confirms the input in the number of people input step 211. Then, go to the preparation display step 212 required for cooking the selected menu is read from the memory 130 to display the food and the amount through the display panel 150.

In the state in which the food and the quantity for the selected menu are displayed as described above, the microcomputer 100 goes to the cooking start key input judging step 213 to determine whether the cooking start key signal of the heating cooking step 260 is input. If the start key signal is not input, the menu display input step 202 is repeated, and if the cooking start key signal is input, the microcomputer 100 goes to the cooking operation step 214 to drive cooking while driving the heater. To get started.

On the other hand, if the menu encouragement key is not pressed in the menu encouragement key input determination step 206, it goes to the cooking key input determination step 209 and judges whether the cooker key is pressed, and displays the menu when the cooker key is not pressed. Starting from the key input step 202, if the user has pressed the cooking key to cook rice, and performs the cooking step (214).

At this time, there is a difference in the cooking method between the food and rice, including soup or stew, when cooking, the cooking is performed by detecting the temperature of the food variable as the heater is driven in the same manner as the usual cooking method In the case of foods with a lot of soup, such as soup or stew, the food is cooked by heating the food for a predetermined heating time according to the menu.

That is, when the user presses the cooking start key or the cooking key of the keyboard unit 110, a high potential signal is output from the output terminal OUT1 of the microcomputer 100 and applied to the base of the transistor TR1 of the heater driving unit 160. As the transistor TR1 conducts, a current flows through the relay RL, so that a relay switch is connected to the heater H to heat the container containing the food.

As the food is heated, the resistance value of the dummyster TH of the temperature sensing unit 120 decreases, the input voltage of the operational amplifier OP decreases gradually, and the temperature detection voltage as described above is calculated by the operational amplifier ( Amplified through the OP) and then input to the input terminal IN1 of the microcomputer 100 through the analog / digital converter 121, the microcomputer 100 of the heater driver 160 according to the output of the temperature sensing unit 120. The operation is controlled to cook food.

In particular, when cooking soup or stew, the heater (H) is driven and at the same time the timer 101 is operated to heat food for a set time according to each menu to perform cooking.

While cooking as described above, the microcomputer 100 goes to the cooking completion step 215 of the cooking completion alarm and the warming step 270 to determine whether the cooking operation is completed, and when the cooking is completed, the output terminal of the microcomputer 100 (OUT2). The high potential signal is outputted through the signal, and the two transistors TR2 and TR3 of the display and alarm unit 170 are turned on by the signal, and thus the display attached to the control panel 2 in the cooking completion alarm step 216. The device 171 is turned on, and at the same time, the buzzer BZ rings for a predetermined time and alerts that cooking is completed, and the microcomputer 100 according to the output data of the temperature sensing unit 120 is heated by the heater driver.
