It works to shine.

  Next, a specific operation method of the operation unit 6 will be described with reference to FIGS.

  First, an operation for selecting and cooking an automatic cooking menu will be described. The user opens the door 3 of the heating cooker and places the object 1 on the table 4, and then closes the door 3. Then, the LED display 24 is controlled by the microcomputer 21, and the automatic cooking menu display parts 6e, 6f, 6g of the operation part 6 are illuminated. Further, the LCD display unit 6d is controlled and displayed.

  Next, when the user rotates the dial 602 of the second input means 6b in the right or left direction, the microcomputer 21 recognizes the setting of auto cooking, and the LCD display unit 6d indicates “auto cooking”. “Character 605 is displayed. Then, the LED display 24 is controlled to illuminate the display section 6i of the second input means 6b and illuminate the “menu selection” character notation. Further, the number of the currently selected auto cooking menu is displayed on the LCD display unit 6d by rotating the dial 602.

  For example, when the number 1 of the auto cooking menu is selected, “1” of the auto cooking menu number is displayed on the LCD display portion 6d, the auto cooking menu display portion 6e is illuminated, and the other auto cooking menu display portions are displayed. The 6f and 6g lights are turned off. Therefore, as shown in FIG. 6, when the illuminated auto cooking menu display section 6e is viewed, it can be determined at a glance that cooking No. 1 in the auto cooking menu is “warming milk”.

  In this manner, an auto cooking menu set in advance by the number of the auto cooking menu selected by rotating the dial 602 can be selected. The automatic cooking menu display sections 6e and 6f are selected depending on whether the number selected by the rotation of the dial 602 is “warm”, “bread / confectionery”, or “baked / fried” in the automatic cooking menu. , 6g lighting is controlled by the LED display 24, so that the desired auto cooking menu can be easily set by classifying even if the number of auto cooking menus is large.

  Next, an example of performing auto cooking for “warming sake” of No. 2 in the “hot” category of the auto cooking menu will be described in detail. The user opens the door 3 of the heating cooker and places the object 1 to be cooked on the table 4, then closes the door 3 and turns the dial 602 of the second input means 6 b to rotate the dial 602. Any of the automatic cooking menu display sections 6e, 6f, 6g corresponding to the classification to which the selected number belongs is illuminated. Then, the dial 602 of the second input means 6b is turned to illuminate the “hot” auto cooking menu display portion 6e, and as shown in FIG. 6, the second “hot for alcohol” in the “hot” category is displayed. After confirmation, the dial 602 is rotated so that the auto cooking menu number displayed on the LCD display unit 6d is 2. Then, the “finished” character notation on the display unit 6 h of the first input means 6 a is illuminated, and the current setting state is displayed beside the “strong, medium, weak” character in the notation 606 indicating the finished setting of the LCD display unit 6 d. Is displayed, and the start key 604 "START" character is flashed and illuminated. The meaning of the blinking illumination indicates a key operation to be operated next. Therefore, if the user wants to change the finishing state of cooking, the user turns the dial 601 to set the cooking finishing state next to the “strong, medium, weak” character 606 in the notation 606 indicating the finishing setting of the LCD display unit 6d. The user can start cooking by operating the start key 604 after setting it to strong, medium or weak while looking at the mark display indicating. Or if it is not necessary to change the finishing state of cooking, the start key 604 is operated as it is to start cooking. Then, the microcomputer 21 selects microwave cooking, and cooks by controlling the microwave output and cooking time by the input of the sensor 22.

  If the cancel key 6c is operated during the operation, the contents of the operation can be canceled to return to the initial state before the operation. Further, when the cancel key 6c is operated after the start of cooking, cooking can be stopped and the initial state before the operation can be restored.

  Next, the manual cooking operation will be described. When the user opens the door 3 of the cooking device and places the object 1 on the table 4, closes the door 3 and rotates the dial 601 right or left, the microcomputer 21 performs manual cooking. Recognizing the setting, the automatic cooking menu display units 6e, 6f, and 6g are turned off, and the "selection" character notation on the display unit 6h of the first input means 6a is illuminated to dial the LCD display unit 6d. The cooking method set by the rotation of 601 is displayed. Further, the “determined” character notation at the center of the dial 601 is illuminated in a blinking manner. Here, when the dial 601 is rotated, the display of the cooking method displayed on the LCD display unit 6d is displayed according to the rotation of the dial 601 such as a range, an oven, steam, and a combination thereof. Therefore, the user selects a desired cooking method by turning the dial 601 and then operates the enter key 603 to determine the cooking method.

  For example, when “RANGE” is selected as the cooking method and the enter key 603 is operated, 500 W, which is the initial value of the cooking output, is displayed on the LCD display portion 6d. At this time, the “selection” continuous illumination on the display unit 6h and the “decision” blinking illumination on the enter key 603 are continued. Therefore, the user selects the cooking output by turning the dial 601 and then operates the enter key 603 to determine the cooking output. Then, the cooking time is then displayed on the LCD display portion 6d, the “time” character notation on the display portion 6h is illuminated, and the “decision” character notation on the enter key 603 is flashed. Then, after the dial 601 is turned to select an appropriate cooking time, the enter key 603 is operated to determine the cooking time. The enter key 603 “determine” character light is turned off and the start key 604 “start” character is turned on. The notation flashes and is illuminated. Therefore, when the start key 604 is operated, cooking is started, and the microcomputer 21 performs cooking by controlling the inverter power supply 8 based on the set microwave output and the set cooking time.

  Thus, since the number of operation keys can be significantly reduced, the amount of movement of the hand for operation is small, and the ease of use can be greatly improved. Moreover, in the operation method of auto cooking and manual cooking, since the input means operated first is clearly separated, it can be easily operated without hesitation. In addition, the input means of the operation unit is divided into manual cooking and automatic cooking, so that the difference between the manual cooking operation method and the automatic cooking operation method is easy for the user to understand. It can be easily operated.

  Next, an operation method for performing manual cooking by microwave cooking with a particularly simple operation will be described. Since the structure of the heating cooker of a present Example is the same as that of Example 1, detailed description is abbreviate | omitted.

  In this embodiment, the user opens the door 3 of the heating cooker and places the object to be cooked 1 on the table 4, then closes the door 3 and operates the enter key 603. "Display, 700W display of output display, and 0 second display of cooking time are displayed. And the "time" character of the display part 6h of the 1st input means 6a is blinked and illuminated. Next, when the cooking time is set while turning the dial 601 while watching the display of the cooking time on the LCD display unit 6d, the blinking illumination of the “time” character on the display unit 6h of the first input means 6a is always illuminated. The “start” character notation of the start key 604 is flashed, and when the start key 604 is operated, cooking is started with a cooking output 700 W in microwave cooking. Also, when the first operation of pressing the enter key 603 is repeated, the output display on the LCD display section 6d changes from 700W to 500W, and this is displayed alternately, so that either output can be easily set and cooking is performed. it can.

  In this way, in the operation unit 6 in which the number of operation keys can be significantly reduced, a cooking method with a high frequency of use, for example, microwave cooking performed at an output of 700 W or 500 W in a microwave oven from only three times. Since cooking can be started by four operations, even the operation unit 6 in which the number of operation keys is greatly reduced does not impair usability.

  Note that such an operation method is not limited to single cooking of a microwave oven, and may be a cooking method that is performed alone or in combination of oven cooking and steam cooking.

  The cooking time is initially displayed as 0 seconds, but if the frequently used cooking time is stored in advance, the determination key 603 is pressed to set the heating output for microwave cooking, and then the start key 604 is operated. By simply doing, cooking can be started immediately, and cooking can be started with a simpler operation.

  As described above, since the number of operation keys can be reduced as compared with the conventional operation unit, the amount of hand movement for operation is small, and the ease of use can be greatly improved. Further, since the operation procedure of the operation keys is easy to understand, it can be easily operated.
