Similarly, other appropriate characters such as "tempura" and "tempura" for "fried food" and "remaining time" and "timer" for "remaining" may be used. As for the graphic "bar graph", a pie graph or other appropriate graphic may be used.

  In the example of FIG. 2, a display example using all of the numbers, characters, and figures for the driving state or the setting state for driving, such as the thermal power, the oil temperature at the time of cooking the fried food, the setting state of the timer, and the remaining time of the timer, is shown. However, it is also conceivable that some of these may be displayed in combination according to the surrounding conditions, product specifications, and the like.

  By performing the above display, even if the user is an elderly person, it can be understood at a glance and is easier to see.

  Next, the cooling structure of the present invention will be described with reference to FIG. The figure is the figure which looked at the inside of the main body 1 from the side, and the arrow has shown the flow of the air.

  As described above, the exhaust port 8 is disposed behind the main body 1, the intake port 9 is disposed above and in front of the main body 1, and the display units 14 and 15 are provided on the top plate 2 surface.

  Reference numeral 16 denotes a display structure portion, which is disposed below the transparent display portions 14 and 15 provided on the top plate 2 surface, and includes operating conditions such as thermal power, oil temperature during fried food cooking, a timer setting state, and a timer remaining time. Alternatively, the setting state for driving is displayed on the display units 14 and 15 by combining all or a part of numbers, characters, and graphics.

  Further, the display structure section 16 has display contents corresponding to each of the induction heaters 17 described later. That is, the user checks the display content corresponding to the induction heater 17 on the right through the transparent display unit 14 provided on the surface of the top plate 2, and displays the display corresponding to the induction heater 17 on the left through the display unit 15. Check the contents. Thereby, since a plurality of remaining timer times can be displayed at the same time, a timer operation of a plurality of induction heaters 17 described later can be simultaneously performed.

  Reference numeral 17 denotes an induction heater, which is composed of a coil, is disposed below the top plate 2, and heats a load such as a pot 20 described later placed above the top plate 2. Reference numeral 18 denotes a temperature sensor, which is arranged at the center of the induction heater 17, that is, the coil, and detects the temperature of the pan 20 described later.

  Reference numeral 19 denotes a blower fan, which is arranged between the intake port 9 and the induction heater 17, sucks cool air outside the main body 1 from the intake port 9, cools the induction heater 17 and the like, and then discharges the same through the exhaust port 8. This is for keeping the induction heater 17 and the like at an appropriate temperature.

  Further, the display structure 16 is arranged near the air inlet 9 and is forcibly cooled by the blower fan 19. Thereby, the display structure 16 is maintained at an appropriate temperature, and the reliability is improved.

  A pan 20 is placed at the right induction heater position 4 or the left induction heater position 5 on the top plate 2 and is heated by the induction heaters 17 arranged at the lower portions thereof.

  The overall operation of the above configuration will be described with reference to FIGS.

  It is assumed that the two pots 20 are heated by the right and left induction heaters 17.

  The two pots 20 are placed on the right induction heater position 4 and the left induction heater position 5 on the top plate 2, and the main switch 11 in the operation panel unit 10 is turned on.

  As a first operation example, a case where the basic operation and the fried food cooking are performed simultaneously will be described.

  An on / off switch 21 in the operation unit 12 for the right induction heater is operated.

  Then, the right induction heater 17 is energized to start heating, and a corresponding heat power display similar to the display example shown in FIG. 2A (heat power display) can be confirmed on the right display unit 14 corresponding thereto. At this time, when the volume knob 24 in the right induction heater operation unit 12 is operated while looking at the display unit 14 to change the setting of the heating power, the numeral and the bar graph indicating the heating power are changed according to the operation, and the desired heating power display and The setting operation is terminated at the point of time when it becomes. Thereafter, heating proceeds with this set thermal power.

  On the other hand, the fried food switch 23 in the operation unit 13 for the left induction heater is operated.

  Then, on the left display section 15 corresponding to the left induction heater 17, a fried food display similar to the display example shown in FIG. 2B (fried food display) can be confirmed. At this time, when the volume knob 24 in the left induction heater operation unit 13 is operated while looking at the display unit 15 to change the set temperature, the numeral indicating the set temperature and the position of the dashed bar graph indicating the set temperature change according to the operation. Then, the setting operation is terminated when the desired temperature is displayed. After that, the oil temperature detected by the temperature sensor 18 increases, and the number of lighting of the bar graph indicating the oil temperature (the solid bar graph in FIG. 2B) changes.

  Next, as a second operation example, a case where two timer operations are performed simultaneously will be described.

  The timer switch 22 in the operation unit 12 for the right induction heater and the operation unit 13 for the left induction heater is operated.

  Then, on the display unit 14 of the induction heater 17 on the right side, the same timer setting time as the display example shown in FIG. 2C (remaining time display), that is, the remaining time display can be confirmed. At this time, when the volume knob 24 in the right induction heater operation unit 12 is operated while looking at the display unit 14 to change the timer setting time, the number indicating the timer setting time changes according to the operation, and the desired timer is changed. Stop operation when time is reached.

  Further, when it is desired to change the heating power, after operating the on / off switch 21 in the right induction heater operation unit 12 and then operating the volume knob 24 in the right induction heater operation unit 12, the lighting number of the bar graph indicating the heating power is reduced. The setting operation is terminated when the power changes to the desired thermal power. Thereafter, the heating proceeds with the set heating power, and the remaining time is displayed on the display unit 14 as a number by subtraction with the passage of time.

  The operation of setting the timer operation of the left induction heater 17 is the same as the case of the timer operation of the right induction heater 17, and a description thereof will be omitted.

  In addition to the two operation examples described above, the three types of heating methods of basic operation, fried food cooking, and timer operation can be used to heat the two right and left induction heaters 17 individually or in combination. Although it is possible, these operation examples are the same as those described above, and a description thereof will be omitted.

  In the above-described example, an example is shown in which the thermal power is simply displayed by a number. However, a method of adding a letter “W” or “kW” near the number to make it easier to understand is also conceivable.

  In addition, when displaying a temperature as in the example of fried food display, a method of adding “° C.” and “degree” to the vicinity of the temperature number and displaying the temperature may be considered.

It is an outline view of one example of the present invention. It is a figure showing the example of a display of the display structure part of one example of the present invention. It is a figure showing the cooling structure of one example of the present invention.
