  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 shows a block diagram of an induction heating cooker according to the first embodiment of the present invention.

  In FIG. 1, a heated object 1, a top plate 2 on which the heated object 1 is placed, a heating coil 3 for inductively heating the bottom surface of the heated object 1 by passing a high-frequency current below the top plate 2, and a heating coil The control part 4 which controls the magnitude | size of the high frequency current which flows into 3 and controls the heating output at the time of heating the to-be-heated material 1 and the time control part 5 which controls heating time are provided. Further, the first operation unit 6 configured by a plurality of touch keys, the second operation unit 7 configured by a plurality of touch keys, and the first operation unit 6 are set on the surface of the top plate 2. A display corresponding to the setting state is configured by a display device such as an LCD or LED, and a display corresponding to the setting state set by the second operation unit 7 is displayed by an LCD or LED. The 2nd display part 9 comprised by is provided.

  FIG. 2 shows the first operation unit 6, the second operation unit 7, the first display unit 8, and the second display unit 9 of the induction heating cooker according to the first embodiment of the present invention. An external view is shown.

  In FIG. 2, the first operation unit 6 includes a down key 6a and an up key 6b for setting a heating power, and the second operation unit 7 includes a minus key 7a for setting a timer and a heating temperature, and a plus key. 7b and a display switching key 7c. A first display unit 8 that displays the thermal power setting is disposed in the vicinity of the first operation unit 6, and a second display that displays a timer, a temperature, and the like in the vicinity of the second operation unit 7. Part 9 is arranged.

  About the induction heating cooking appliance comprised as mentioned above, the operation | movement and an effect | action are demonstrated below using FIG. 3, FIG.

  3 and 4 are flowcharts showing operations of the second operation unit 7 and the second display unit 9.

  In FIG. 3, first, in step 101, a power switch (not shown) is turned on. Next, in step 102, it is determined whether or not the minus key 7a or the plus key 7b of the second operation unit 7 is pressed. When the minus key 7a or the plus key 7b of the second operation unit 7 is pressed, the process proceeds to step 103, and the timer time set on the second display unit 9 is displayed. Next, in step 104, it is determined whether or not the heating off / on key 11 has been pressed. When the heating off / on key 11 is pressed, the routine proceeds to step 105, where heating is started. When heating is started in step 105, the process proceeds to step 106, and it is determined whether or not the set timer time has elapsed. When the set timer time has elapsed, the routine proceeds to step 108 and heating is stopped. If the set timer time has not elapsed, the routine proceeds to step 107, where it is determined whether or not the heating off / on key 11 has been pressed. When the heating off / on key 11 is pressed, the routine proceeds to step 108 and the heating is stopped. If the heating off / on key 11 has not been pressed, the process returns to step 106.

  In FIG. 4, first, in step 109, a power switch (not shown) is turned on. Next, in step 110, the menu key 10 is used to set the deep-fried food mode. Next, in step 111, it is determined whether or not the heating off / on key 11 has been pressed. When the heating off / on key 11 is pressed, the routine proceeds to step 112, where heating is started. When heating is started in step 112, the process proceeds to step 113 and the set heating temperature is displayed on the second display unit 9. Next, in step 114, it is determined whether or not the minus key 7a or the plus key 7b of the second operation unit 7 is pressed. When the minus key 7a or the plus key 7b of the second operation unit 7 is pressed, the process proceeds to step 115 where the set heating temperature is updated and displayed on the second display unit 9 again. Next, in step 116, it is determined whether or not the heating off / on key 11 has been pressed. When the heating off / on key 11 is pressed, the routine proceeds to step 117, where heating is stopped. If the heating off / on key 11 has not been pressed, the process returns to step 114.

  As described above, in the present embodiment, by providing the second operation unit 7 for setting the heating temperature in the vicinity of the second display unit 9 for displaying the heating temperature, the operability is improved and the usability is improved. Can do well.

  When the first display unit 8 is not displaying and the second display unit 9 is displaying, the setting displayed on the second display unit 9 is changed to the first operation unit. 6 and the second operation unit 7 can be set. For example, in the deep-fried food mode, no display is made on the first display unit 8, and the set heating temperature is displayed on the second display unit 9. When the heating temperature is set, the first operation unit 6 is used. However, the second operating unit 7 can also set the heating temperature. In the automatic rice cooking mode, no display is made on the first display unit 8, and the number of cups is displayed on the second display unit 9. When setting the number, the number of cups can be set by either the first operation unit 6 or the second operation unit 7. In addition, when both the first display unit 8 and the second display unit 9 are displayed, the settings displayed on the first display unit 8 are set by the first operation unit 6 and the second display The settings displayed on the unit 9 can be set on the second operation unit 7. For example, in the timer heating mode, the set heating power is displayed on the first display unit 8, the timer setting time is displayed on the second display unit 9, and the first operation unit is used when setting the heating power. When the thermal power setting is performed at 6 and the timer setting is performed, the timer setting is performed at the second operation unit 7.

  As described above, when the display is not performed on the first display unit 8 and the display is performed on the second display unit 9, the setting displayed on the second display unit 9 is set to the first display unit 9. When the first display unit 8 and the second display unit 9 are displayed, the setting displayed on the first display unit 8 can be set by the operation unit 6 and the second operation unit 7. Is set by the first operation unit 6 and the setting displayed on the second display unit 9 can be set by the second operation unit 7 so that the user can operate without confusion. Yes, it can improve usability.

  Note that the second operation unit 7 may be positioned closer to the front side than the second display unit 9 on the back side, with the user's standing position as the front side. Thereby, when setting heating temperature, the operativity of the 2nd operation part 7 which sets heating temperature becomes good, and can improve usability.

  The second display unit 9 can perform abnormality display, automatic cooking setting display, and current temperature display, and can be switched appropriately within the same region by operating the display switching key 7c of the second operation unit 7. Can be displayed.

  Moreover, although the case where there are two heating coils is shown in the present embodiment, there may be one or three or more.

  As described above, since the induction heating cooker according to the present invention is provided with an operation part for setting the heating temperature in the vicinity of the display part of the heating temperature, the operability is improved and the usability can be improved. The present invention can also be applied to uses such as a cooking device having a display unit and an operation unit such as an induction cooking device, a high-frequency cooking device, and a halogen cooking device.
