Furthermore, the induction heating cooker 1 is provided with a temperature detector 40, which detects the temperature of the object to be heated.

  The control unit 21 includes a light emission adjustment unit 22, a time measurement unit 23, a storage unit 24, and a rotation detection unit 25, and the light emission adjustment unit 22 adjusts the light emission pattern of the light emission unit 6. . FIGS. 7A, 7 </ b> B, and 7 </ b> C are perspective views showing lighting of the light emitting unit 6 in the first embodiment. 7A is a perspective view showing that the light emitting unit 6 is turned off, FIG. 7B is a perspective view showing that the light emitting unit 6 is turned on, and FIG. 7C. These are perspective views which show that the light emission part 6 is lighting in the color different from FIG.7 (b). When heating by the heating unit 4 is not performed, as illustrated in FIG. 7A, the heating operation unit 5a is housed in the operation panel 5, and the light emission adjusting unit 22 turns off the light emitting unit 6. To do. This state is an off state in which the operation of the heating unit 4 is not performed. When the heating operation unit 5a is pressed from this state, as shown in FIG. 7B, the heating operation unit 5a protrudes from the operation panel 5, and then the heating operation unit 5a is rotated to a predetermined position. Then, the light emission adjusting unit 22 lights the light emitting unit 6 in blue. This predetermined position is a position for preparing a heating state in which the heating power of the heating unit 4 can be adjusted. When the heating operation unit 5a is further rotated from this state, the operation of the heating unit 4 is started, and the light emission adjusting unit 22 lights the light emitting unit 6 in red as shown in FIG. 7C. To do. That is, this state is a heating power input state of the heating unit 4.

  In addition to the light emission adjusting unit 22, the time measuring unit 23 provided in the control unit 21 measures the heating time of the heating unit 4. The storage unit 24 stores a predetermined heating time threshold value, a light emission pattern of the light emitting unit 6, and the like. The heating time threshold value is compared with the heating time measured by the time measuring unit 23. The light emission adjusting unit 22 controls the light emitting unit 6 based on the comparison result, and is used to promote adjustment of the heating power in the heating unit 4.

  In addition, this heating time threshold value can also be changed by the heating power of the heating unit 4 in order to suppress excessive heating of the object to be heated. Specifically, when the heating power of the heating unit 4 is low, the object to be heated is difficult to be heated excessively, so the heating time threshold is set to a large value. On the other hand, when the heating power of the heating unit 4 is medium or strong, the object to be heated may be heated excessively, so the heating time threshold is set to a small value. And this heating time threshold value may be preset at the time of factory shipment of the induction heating cooking appliance 1, and can also be comprised so that a user may change suitably. Furthermore, the rotation detection unit 25 detects a rotation angle when the heating operation unit 5a is rotated. Information on the rotation angle detected by the rotation detection unit 25 is transmitted to the inverter circuit 31, and the heating power of the heating unit 4 is controlled.

  Next, operation | movement of the induction heating cooking appliance 1 which concerns on this Embodiment 1 is demonstrated. FIG. 8 is a first flowchart showing the control of induction heating cooker 1 according to the first embodiment. As shown in FIG. 8, first, when the power switch 5b is turned on, the light emitting unit 6 around the heating operation unit 5a is lit for a predetermined time (step S1). At this time, the fact that the power switch 5b has been turned on is notified not only by the lighting of the light emitting unit 6, but also by sound emitted from the speaker 36. And the control part 21 determines whether the heating operation part 5a was pushed down and the heating operation part 5a was pushed out from the operation panel 5 (step S2). If the heating operation unit 5a is not pushed out, the process returns to step S1 (No in step S2). On the other hand, if the heating operation unit 5a is pushed out, the process proceeds to the next step S3 (Yes in step S2).

  In the next step S3, the light emitting unit 6 around the pressed heating operation unit 5a blinks in blue. That is, the light emission adjusting unit 22 blinks the first light emitting unit 6a. Thereby, the person in the place away from the induction heating cooking appliance 1 can also recognize that it is the stage where the heating operation part 5a was pressed down. Thereafter, the rotation detection unit 25 determines whether or not the heating operation unit 5a has been rotated to a predetermined position (step S4). As described above, the predetermined position is a position for setting the heating unit 4 in a preparation state in which the operation of the heating unit 4 can be performed. If the rotation detection unit 25 does not detect that the heating operation unit 5a has been rotated to a predetermined position, the process returns to step S3 (No in step S4). On the other hand, if the heating operation unit 5a is rotated to a predetermined position, the process proceeds to the next step S5 (Yes in step S4).

  In the next step S5, the light emitting unit 6 around the heating operation unit 5a that has been rotated to a predetermined position changes from flashing blue to lighting. That is, the light emission adjusting unit 22 lights the first light emitting unit 6a. Thereby, the person in the place away from the induction heating cooking appliance 1 can recognize that the heating operation part 5a is rotated to a predetermined position and the heating part 4 is in a ready state. Then, the rotation detection unit 25 determines whether or not the heating operation unit 5a is further rotated (step S6). When the heating operation unit 5a is further rotated from a predetermined position, the operation of the heating unit 4 is started. When the heating operation unit 5a is not rotated and remains in a predetermined position, the process returns to step S5 (No in step S6). On the other hand, if the heating operation unit 5a is further rotated, the process proceeds to the next step S7 (Yes in step S6).

  In the next step S7, the light emitting unit 6 around the heating operation unit 5a further rotated from a predetermined position is lit in red. That is, the light emission adjusting unit 22 lights the second light emitting unit 6b. Thereby, the person who exists in the place away from the induction heating cooking appliance 1 can recognize that the heating operation part 5a is further rotated from the predetermined position and the heating part 4 is operating. In this manner, the light emitting unit 6 around the heating operation unit 5a is lit red and the heating power of the heating unit 4 is turned on (step S8).

  FIG. 9 is a second flowchart showing the control of induction heating cooker 1 according to the first embodiment. In step S8 of FIG. 8 (first flowchart), when the heating power of the heating unit 4 is turned on, the induction heating cooker 1 is subsequently controlled based on the second flowchart. As shown in FIG. 9, when the heating power of the heating unit 4 is turned on, the time counting unit 23 measures the heating time by the heating unit 4 (step S <b> 11). And it is determined whether the heating time measured by the time measuring part 23 exceeded the heating time threshold memorize | stored by the memory | storage part 24 (step S12). When it is determined that the heating time measured by the timer unit 23 does not exceed the heating time threshold, the process returns to step S11 (No in step S12). On the other hand, if it determines with the heating time measured by the time measuring part 23 being over the heating time threshold value, it will progress to the following step S13 (Yes of step S12).

  In the next step S13, the light emitting unit 6 around the heating operation unit 5a corresponding to the heating unit 4 for which the heating time has been measured changes from red lighting to blinking. That is, the light emission adjusting unit 22 blinks the second light emitting unit 6b. Here, the case where the to-be-heated material heated by the heating unit 4 is curry will be described. When cooking curry, the quality of curry can be improved by adjusting the baking color of onions contained in the curry. Then, the display unit 13 provided on the top 2 displays a message “When the onion becomes dark brown, please lower the heating power from 8 to 4.” In this case, the heating power of the heating unit 4 is 8 for strong fire and 4 for medium heat. In the present embodiment, in addition to the display by the display unit 13, the light emission adjusting unit 22 blinks the light emitting units 6 around the heating operation unit 5a corresponding to the mounting unit 3 on which the curry is mounted in step S13. Let If the storage unit 24 stores the heating time threshold value as 0 s, the light emitting unit 6 can be blinked immediately after the start of heating.

  Thus, when the light emission adjustment part 22 needs to adjust the heating power of the heating part 4, in order to make the light emission part 6 blink, the user of the induction heating cooking appliance 1 left | separated from the induction heating cooking appliance 1. Even in the place, it is possible to recognize the necessity of adjusting the thermal power by the blinking of the light emitting unit 6. In addition, although the control part 21 can also output the sound of "If an onion turns into a tan color, please lower a heat power from 8 to 4,", the user of the induction heating cooking appliance 1 can also output. If you are deaf, this voice is difficult to hear. However, in the present embodiment, since the light emission adjusting unit 22 blinks the light emitting unit 6, even a user who is deaf can recognize whether or not the adjustment of the thermal power is necessary.

  After step S13, the rotation detection unit 25 determines whether or not the heating operation unit 5a has been rotated (step S14). If the rotation detecting unit 25 does not detect that the heating operation unit 5a has been rotated, the process returns to step S13 (No in step S14). On the other hand, if the rotation detecting unit 25 detects that the heating operation unit 5a has been rotated, for example, in the low heat direction, the process proceeds to the next step S15 (Yes in step S14). In the next step S15, the light emitting unit 6 around the heating operation unit 5a corresponding to the heating unit 4 for which the heating time has been measured changes from flashing red to lighting. That is, the light emission adjusting unit 22 lights the second light emitting unit 6b. In this state, heating by the heating unit 4 is continued.

  Further, when the cooking menu corresponding to the type of the object to be heated or the cooking means is selected by the menu operation unit 3a arranged in the upper heating unit 1a, the light emission adjusting unit 22 includes the first light emitting unit 6a and All of the second light emitting units 6b are turned on and turned on in pink. As described above, in this embodiment, when the cooking menu is selected, the lighting unit lights in pink different from red during normal heating when the cooking menu is not selected. Or it can make it easy to recognize whether it is normal cooking.

  As described above, the light emission adjusting unit 22 changes the light emission pattern of the light emitting unit 6 according to the status of the induction heating cooker 1. FIG. 10 is a diagram showing a light emission pattern of the light emitting unit 6 in the first embodiment. As shown in FIG. 10, when the heating unit 4 is off, that is, when the heating operation unit 5 a is accommodated in the operation panel 5, the light emitting unit 6 is turned off. And when the heating operation part 5a protrudes, the light emission part 6 blinks in blue (step S3 of FIG. 8). Further, when the heating operation unit 5a is rotated to a predetermined position, that is, when the heating unit 4 is in a preparation state, the light emitting unit 6 is lit in blue (step S5 in FIG. 8). Further, when the heating operation unit 5a is further rotated from a predetermined position and the heating unit 4 is in a heating state, the light emitting unit 6 is lit in red (step S7 in FIG. 8). Then, after the heating threshold time has elapsed from the start of heating, that is, when the user is urged to adjust the heating power of the heating unit 4, the light emitting unit 6 blinks red (step S13 in FIG. 9). . And in the heating at the time of cooking menu selection, the light emission part 6 lights in pink.

  In addition, said light emission pattern is only an example, For example, the light emission color of the light emission part 6 can be changed, and the blinking speed can also be changed. Examples of the means for changing the emission color include changing the gradation of the first light emitting unit 6a and the second light emitting unit 6b, and further adding a third light emitting unit. In the present embodiment, the induction heating cooker 1 may be provided with a function for forcibly turning off the light emitting unit 6. Thereby, when the user does not need the light emission of the light emission part 6, light emission of the light emission part 6 can be stopped.

  Furthermore, when an abnormality occurs during cooking, the light emission adjusting unit 22 may cause the light emitting unit 6 to blink at a faster blinking speed than the blinking for notifying whether or not the heating power needs to be adjusted as described above. it can. For example, when the spill detection unit 39 provided in the induction heating cooker 1 detects liquid spilled from the object to be heated, the controller 21 recognizes that it is in an abnormal state, and the light emission adjustment unit 22 The flashing speed of the light emitting unit 6 is increased. As another example, when the temperature of the object to be heated detected by the temperature detection unit 40 provided in the induction heating cooker 1 is higher than a predetermined temperature, the controller 21 is in an abnormal state. The light emission adjusting unit 22 increases the blinking speed of the light emitting unit 6.

  As described above, the present embodiment provides the heating operation unit 5a in consideration of universal design (UD) and safety by providing the light emitting unit 6 around the heating operation unit 5a to enhance the visibility. Can be realized. Moreover, the light-emitting unit 6 in the heating operation unit 5a corresponding to the placement unit 3 on which the object to be heated is placed is turned on or blinked, thereby preventing the heating operation unit 5a other than the operation target from being erroneously operated. There is an effect that can be done.

From this state, when the heating operation unit 5a is touched, the light emitting unit 6 is lit in blue as shown in FIG. This state is a preparation state in which the operation of the heating unit 4 can be performed. Then, from this state, for example, when the user's finger is traced along the peripheral edge of the heating operation unit 5a, the operation of the heating unit 4 is started. As shown in FIG. Lights red. That is, this state is a heating power input state of the heating unit 4.

  Thus, in this Embodiment, since the heating operation part 5a is comprised with the touch panel, the heating operation part 5a can be integrally formed with the operation panel 5. FIG. For this reason, in addition to the effect obtained in Embodiment 1, there is an effect that the number of parts can be reduced. Moreover, since the heating operation part 5a does not protrude from the operation panel 5, the operation panel 5 can be easily cleaned.

  In the present embodiment, the heating operation unit 5a may be provided with vibration generating means such as a vibration motor so that the heating operation unit 5a vibrates when contacting the heating operation unit 5a. Thereby, when it contacts the heating operation part 5a, the feedback by vibration is performed and it can recognize that operation is performed normally.
