On the back side of the operation panel 37, a micro switch 48 is provided. In the microswitch 48, the tip of the actuator 48a is in contact with the back surface of the cylindrical portion 46 of the dial 43. Thus, as shown in FIG. 5A, when the dial 43 is in the storage position, the micro switch 48 is turned off, and when the dial 43 is in the protruding position, as shown in FIG. 48 is turned on. In this case, the ON / OFF signal of the microswitch 48 is input to the control circuit 38 to perform a function for starting (executing) or stopping the operation of the induction heating unit 29 as described later. ing.

Further, a rotary encoder 49 is provided on the back side of the operation panel 37 so as to correspond to the dial 43. The rotary encoder 49 is connected to the shaft portion 47 of the cylindrical portion 46, and outputs a pulse signal according to the turning operation direction and the turning amount of the dial 43 when the dial 43 (the cylindrical portion 46) is at the projecting position. It is configured to output to the control circuit 38. Thereby, a function for adjusting the output of the corresponding induction heating unit 29 is performed.

FIG. 6 is a diagram showing an example of an output signal from the rotary encoder 49. For example, when the dial 43 is rotated clockwise, as shown in FIG. 6A, after a pulse signal is output from the terminal A, a pulse signal is output from the terminal B with a delay of a certain time (T0). You. On the other hand, when the dial 43 is turned counterclockwise, a pulse signal is output from the terminal A after a pulse signal is output from the terminal B with a delay of a predetermined time (T0).

The terminals A and B of the rotary encoder 49 are connected to the control circuit 38 as shown in FIG. Thereby, the control circuit 38 is configured to detect the rotation direction of the dial 43 based on the phases of the pulse signals output from the terminals A and B, and to detect the rotation amount of the dial 43 based on the number of pulses. ing.

The dials 44 and 45 have the same configuration as the dial 43. Accordingly, as shown in FIG. 4, the micro switch 50 and the rotary encoder 51 are provided on the dial 44, and the micro switch 52 and the rotary encoder 5 are provided on the dial 45.
3 are provided corresponding to each other, and are connected to the control circuit 38. The control circuit 38 includes a radiant heater 28, a roaster 36 (seed heater),
The induction heating coils 26 and 27 are connected via a drive circuit 54. Further, the control circuit 38 controls the display unit 32
To 34 and the high-temperature caution display section 35 and the like (shown by a display device 55 in FIG. 4).

Here, the induction heating unit 29 on the left side can adjust the output to seven levels of "1 to 6" and "strong".
As illustrated in FIG. 3, the left display unit 32 includes characters “1 to 6” and “strong” and seven LEDs 32a corresponding thereto.
The current output is displayed by turning on the LED 32a. Also, the induction heating unit 30 on the right side
The output can be adjusted to six levels of “1 to 6”, and the right display unit 33 displays the characters “1 to 6” and the corresponding 6
The LED 33a is provided, and the current output is displayed by turning on the LED 33a. At this time, the output of the induction heating section 32 on the left side and the output of the induction heating section 33 on the right side are set to be equal if the level numbers are the same. Therefore, for example, the output level “6”
In the case of the above, 2k is applied to both the heating units 32 and 33.
W output.

In the induction heating sections 32 and 33,
When the dials 43 and 45 are displaced from the storage positions to the protruding positions, the control circuit 38 controls the micro switches 48 and 52
In response to the input of the ON signal from the control unit, a preset heating output, for example, an output “5” is output by the induction heating coil 26,
27 is started.

Although the detailed description is omitted, the induction heating unit 32 on the right side is operated by the
It is possible to execute a “tempura cooking mode” in which the induction heating coil 26 is controlled so that the object to be heated is controlled to the set temperature based on the temperature detection of the object to be heated. Therefore, the tempura mode display lamp 56
Are provided, and L of "2", "4", "6"
The ED 34a also serves as a set temperature display of 160 ° C, 180 ° C, and 200 ° C.

On the other hand, the heater heating unit 31 can adjust the output to three levels of “strong”, “medium”, and “weak”, and the middle display unit 33 displays “strong”, “medium”, “ The character "weak" and three LEDs corresponding thereto are provided, and the current output is displayed by turning on the LED 33a. Then, in the heater heating unit 31, the dial 4
When the button 4 is pressed and displaced from the storage position to the protruding position, the control circuit 38 is configured to put the coil heater 28 into a heating start preparation state in response to an ON signal input from the microswitch 50. Have been.

Here, the heating / heating preparation state means a state in which heating is started only when the dial 44 is rotated, and at this time, the output of the heater heating unit 31 is:
Switching can be performed by rotating the dial 44.

On the other hand, the roaster 36 can adjust the output to three levels of “strong”, “medium” and “weak”, and the roaster key 41 has “strong”, “medium”, “ weak"
And three LEDs 41a corresponding thereto are provided, and the current output is displayed by turning on the LED 41a. The on / off operation and output adjustment of the roaster 36 are performed by operating the dial 44 while the roaster key 41 is pressed. At this time, when the dial 44 is displaced from the storage position to the protruding position, the control circuit 38 starts the operation of the roaster 36 with the output “medium”, and the output is adjusted by rotating the dial 44.

That is, the center dial 44 is configured so as to be selectively used in a first mode in which the heating operation is started when switching from the storage position to the projecting position, and in a second mode in which the heating operation is ready. It is. The first mode is a mode of heating and cooking by the roaster 36, and the second mode is a mode of heating and cooking in the heater heating unit 31. When the roaster key 41 is in the pressed state, the roaster key 41 is lit and the dial 4
4 is configured to display that it is functioning as an operating means for the roaster 36.

Now, the operation of the above configuration will be described.
When performing induction heating cooking, the user places an object to be heated such as a pot on one of the left and right induction heating units 29 and 30. Here, in order to perform heating cooking requiring a relatively strong heat, the induction heating unit 2 having a maximum output of 3 kW on the left side.
The case where 9 is used will be described as an example.

First, the user checks the position of the dial 43 corresponding to the induction heating unit 29 on the left side, and switches the storage position from the storage position to the protrusion position by pressing the dial 43. Thereby, the induction heating unit 29 on the left side performs the heating operation with the output “5”, and at the same time, the LED 32 a of the left display unit 32 on the top plate 25 is turned on, and the output is “5”. indicate.

At this time, if an even higher heating power is required, the output is increased by turning the dial 43 clockwise while watching the display on the left display section 32. To weaken the output, the dial 43 is turned counterclockwise to lower the output. Then, when cooking is completed, the heating operation in the induction heating unit 29 is stopped by pressing the dial 43 to the storage position.

On the other hand, when performing heater heating cooking, the user places an object to be heated on the heater heating unit 31 and presses the dial 44 corresponding to the heater heating unit 31 to protrude from the storage position. Switch to position. As a result, the heater heating unit 31 enters a heating preparation state, and the high-temperature warning display unit 35 is turned on. Then, when the user rotates the dial 44, the heater heating unit 31 starts the heating operation, and thereafter, the output is changed by the rotating operation of the dial 44. At this time, the LED 33a of the middle display section 33 displays the current output. Also, when cooking is completed,
The heating operation in the heater heating unit 31 is stopped by pressing the dial 44 to the storage position.

On the other hand, when the roaster 36 is used, the user places an object to be heated such as a fish in the roaster 36 and presses the roaster key 41.
Then, when the dial 44 is pressed and displaced to the protruding position, the roaster 36 starts the heating operation with the output “medium”. At the same time, the LED 41a provided on the roaster key 41 is turned on to indicate that the output is "medium". In this case as well, the output can be switched by rotating the dial 44, and the dial 4
By pressing the button 4 to set it in the storage position, the heating cooking can be stopped.

According to the present embodiment having such a configuration, the display units 32-3 for displaying the current outputs of the heating units 29-31.
4 was arranged on the top plate 25, and dials 43 to 45 were arranged on the operation panel 37. Therefore, the display units 32-34 are placed near the heating units 29-31 and
Since the heaters 29 to 31 can be provided corresponding to the positions of the heaters 29 to 31, the display on the display units 32 to 34 can be confirmed without greatly moving the line of sight from the object to be heated on the heaters 29 to 31.

On the other hand, in the operation panel 37, since the display portions 32 to 34 are provided on the top plate 25, the space for providing the dials 43 to 45 can be made large, so that the user can adjust the shape of the dials 43 to 45. It can be designed to be easy to operate. Therefore, the user can operate the dials 43 to 45 corresponding to the heating unit to be used without bending down the posture each time the dials 43 to 45 are operated and checking the position. for that reason,
Even when the dials 43 to 45 are operated while looking at the display units 32 to 34, erroneous operations of the dials 43 to 45 can be prevented as much as possible.

In the present embodiment, the dial 43
45 are configured so that the storage position can be moved in and out of the protruding position. When not cooking, dial 4
Since the positions 3 to 45 can be set to the storage positions and can be flush with the operation panel 37, the dials 43 to 45 do not hinder the cleaning, and the cleaning performance is improved. In addition, dial 43
To 45 can be turned on and off by displacing the heat sources between the protruding position and the storage position, and by turning the dials 43 to 45 at the protruding position, the output of each heat source can be changed. It was configured so that it could be adjusted. As a result, the number of dials and switches on the operation panel 37 can be reduced and the number of switches and switches on the operation panel 37 can be reduced in comparison with a case where the on / off operation and the output adjustment are performed by separate operation means.

Further, in the induction heating units 29 and 30, when the dials 43 and 45 are displaced from the storage positions to the protruding positions, the heating operation is started at the output "5". Moreover, considering that there are many cooking methods that cook with relatively strong heat until heating progresses to some extent,
The heating operation is started at a relatively high output “5”. Therefore, the heating operation is started only by switching the dials 43 and 45 from the storage position to the protruding position, so that the operation for adjusting the output can be omitted and the usability is improved.

Further, since the dial 44 is configured so that the operation means of the heater heating unit 31 and the operation means of the roaster 36 can be switched by pressing the roaster key 41, the operation is different from the case where the operation means is separately provided. The number of dials can be reduced. Then, when the dial 44 functions as the operating means for the roaster 36, a message to that effect is displayed, so that the user can visually check the state of the dial 44.

The dial 44 is connected to the heater heating section 31.
When the dial 44 is displaced from the storage position to the protruding position, the heating preparation state is established. This is because the induction heating units 29 and 30
This is because, unlike the heater heating unit 31, the temperature of the top plate 25 becomes high due to the heat generated by the radiant heater 28. Thus, when the dial 44 is pressed by mistake, the heating operation in the heater heating unit 31 can be prevented from being started, and safety is improved.

When the dial 44 functions as operating means for the roaster 36, the heating operation is started at a predetermined output when the dial 44 is displaced from the storage position to the protruding position. This is because, unlike the heater heating unit 31, the influence of the heat of the roaster 36 on the outside is small, so that the risk of malfunction is small. Therefore, also in this case, the effect that the operability is improved is obtained as in the case of the induction heating units 29 and 30.

Further, in this embodiment, even when two induction heating units 29 and 30 having different maximum outputs are provided, the amount of rotation of the dials 43 and 45 corresponding to the respective induction heating units 29 and 30 is limited. The heating output was changed so as to have the same change amount. Therefore, the induction heating sections 29, 3
It is not necessary to change the amount of rotation of the dials 43 and 45 in accordance with the maximum output of 0, and the operability is improved.

The rotary amounts of the dials 43, 44, 45 are detected by the rotary encoders 49, 51, 53. Therefore, the detection of the amount of rotation of the dials 43 to 45 can be made simple and reliable.

FIG. 7 shows a second embodiment of the present invention, which differs from the first embodiment in the following points. That is, in the second embodiment, the dial 43 as the operation knob is constituted by the outer cylinder portion 61, the pressing portion 62 fitted into the outer cylinder portion 61, and the coil spring 63.
The other dials 44 and 45 have the same configuration.

And. The right opening end of the outer cylinder 61 shown in the figure is rotatably connected to a rotary encoder 49, and the amount and direction of rotation of the outer cylinder 61 are detected by the rotary encoder 49. ing.

A tact switch 64 is provided in a concave portion 49a provided at the center of the rotary encoder 49.
Is installed. Then, each time the user presses the pressing portion 62, the pressing portion 62 is displaced in the axial direction, the tact switch 64 is turned on, and an operation signal is output.
