When heating is performed, the heating operation is performed in a state where the above-mentioned rotating dish is attached and the food is placed on the rotating dish. On the other hand, when performing heating cooking using an electric heater, the heating operation is performed in a state where the rotating plate is removed and the food is placed on a shelf board or the like.

In the above configuration, it is prohibited to perform heating by the magnetron while forgetting to attach the rotating plate, and to perform heating by the electric heater while attaching the rotating plate. Therefore, in such a heating cooker, the presence or absence of the rotating dish is detected by a weight sensor provided for performing automatic cooking and detecting the weight of the food.
Thus, for example, when the user forgets to remove the rotating plate, selects the cooking setting switch used for heating cooking by the electric heater, and then performs an operation start operation, an error is displayed and the operation is not performed. Like that.

(Problems to be Solved by the Invention) In the above-described conventional configuration, the cooking setting switch is selectively operated,
Then, after performing the operation start operation, an error display is performed. Therefore, in order to normally perform the heating operation in the above case, after removing the rotating plate, the same operation as the first operation must be performed again, that is, the cooking setting switch must be selected and the operation must be started. However, the operability was poor and the usability was poor.

Therefore, an object of the present invention is to provide a heating cooker that can prevent erroneous operations and improve usability.

[Structure of the Invention] (Means for Solving the Problems) The heating cooker of the present invention includes a magnetron that microwave-heats an object to be heated, and an electric heater that heats the object to be heated. In a device in which accessories used for heating are detachably provided in a cooking chamber, a first cooking setting switch group used for heating cooking by the magnetron is provided, and for heating cooking by the electric heater, A second cooking setting switch group to be used, a plurality of switch illuminating elements provided to respectively illuminate the respective cooking setting switches, and a detecting means for detecting the presence or absence of the accessory. If the detection result by the detection means is “present” before the operation of the cooking setting switch, the first cooking setting switch group is illuminated to perform the detection. Fruit has characterized in that and a lighting control means for driving and controlling the switching illumination element to illuminate the second cooking select keys if "NO".

(Operation) According to the above-mentioned means, for example, when an accessory is attached, the detection result by the detection means becomes “present”, and before the operation of each cooking setting switch, the second one used for heating cooking by the magnetron is used. One cooking setting switch group is illuminated. Therefore, when the user wants to heat and cook with the electric heater in such a state, the second cooking setting switch group used for that purpose is not illuminated, and the user forgets to remove the accessory. Get noticed immediately. Also, contrary to the above, if no accessories are attached, before operating each cooking setting switch,
Since the second cooking setting switch group is illuminated, the first cooking setting switch group used for that purpose is not illuminated when the user desires heating cooking by the magnetron in such a state. You will soon notice that you have forgotten to install accessories. Therefore, unlike the related art, erroneous operation can be prevented, and it becomes unnecessary to perform the operation again.

I am going to receive it. The microcomputer 41 controls the driving of the electric heater 6 and the magnetron 44 via the driving circuits 45 and 46, and controls the driving of the display unit 36. The microcomputer 41 drives and controls a switch illumination unit 47 having a plurality of switch illumination elements 35.

Next, the operation of the above configuration will be described with reference to FIG.
FIG. 1 is a flowchart mainly showing a switch illumination function part of the control program stored in the microcomputer 41. As shown in FIG. 1, when the door 3 is closed, the door switch 43 is turned off (proceed to “YES” in step S1), and the presence or absence of the rotating plate 12 before the operation of each of the cooking setting switches 15 to 31 is performed. Is determined. Here, since the weight detected by the weight sensor 9 differs depending on whether or not the rotating plate 12 is placed on the rotating plate 11, the rotating plate 12 is determined based on the level of the weight information detection signal that is the detection result of the weight sensor 9.
You can see 12 "Yes" and "No". Rotating plate 12 is "Yes"
In step S2, the process proceeds to "YES" in step S2, in which the switch lighting elements 35 corresponding to the first cooking setting switch groups 15 to 21 used for heating cooking by the magnetron 44 emit light, and the switch groups 15 to Light 21 (Step S
3). And, the cooking setting switch 15-2 desired by the user
When 1 is pressed (step S4), only the operated switches 15 to 21 are illuminated, and the remaining switches 15 to 21 are turned off by turning off the switch illumination element 35 (step S5). In step S4, the state in which none of the cooking setting switches 15 to 21 is pressed is one.
After a lapse of one minute, the switch lighting element 35 is turned off to stop illuminating the cooking setting switches 15 to 21, and the process returns to step S1 (steps S6 and S7). Well, step S5
Subsequently, when the start switch 37 is pressed (step 8), the cooking operation is started in the set cooking mode (step S9). Then, when the cooking is completed, the switch lighting element 31 which has been emitting light is turned off to stop illuminating the cooking setting switches 15 to 21 (step S1).
0 and S11).

On the other hand, when the rotating plate 12 is "none", the process proceeds to "NO" in step S2, and the switch lighting element corresponding to the second cooking setting switch group 22 to 31 used for heating cooking by the electric heater 6 The switch group 22 to 31 is illuminated by emitting 35 light (step S12). Subsequent processing proceeds in substantially the same manner as described above. That is, the user sets the cooking setting switch
After pressing a desired one from 22 to 31, the start switch 37 is pressed to start the cooking operation.

According to the present embodiment having such a configuration, when the rotating plate 12 is mounted in the heating cooking chamber 2, the detection result of the weight sensor 9 is “Yes”, and each of the cooking setting switches 15 to
Prior to the operation of 31, the first cooking setting switches 15 to 21 used for heating cooking by the magnetron 44 are illuminated. Therefore, when the user wants to perform heating cooking by the electric heater 6 in such a state, the second cooking setting switch groups 22 to 31 used for that purpose are not illuminated. Rotating pan 12 before operation 31
Notice that you have forgotten to remove the. Conversely, when the rotating dish 12 is not mounted, the second cooking setting switch group 22 to 31 is illuminated before the operation of each of the cooking setting switches 15 to 31. When the user wants to cook by magnetron in a proper state, the first cooking setting switch group 15-21 used for that purpose is not illuminated, so the user rotates before operating the cooking setting switches 15-31. You will notice that you forgot to install the tray 12. For this reason, erroneous operation can be prevented, so that the usability can be improved as compared with the related art in which after performing the erroneous operation, the rotating plate is attached or detached and the same operation as the first operation is repeated again.

[Effects of the Invention] As is clear from the above description, the present invention includes a detecting means for detecting the presence or absence of an accessory, and if the detection result by the detecting means is "present" before the operation of each cooking setting switch, the magnetron. First used for cooking by
Illuminating the second set of cooking setting switches used for heating cooking by the electric heater if the detection result is "none". With the configuration including the control means, before operating each of the cooking setting switches, it is possible to notice that the user has forgotten to attach or remove the accessories used for heating by the magnetron in the heating cooking chamber, thereby preventing erroneous operation. It has an excellent effect that the usability can be improved.
