And a plurality of inverter circuits that are provided corresponding to the plurality of heating coils, convert DC power into high frequency power, and supply the power to the plurality of heating coils, respectively, and the top plate includes a first heating zone section. The second heating zone portion indicating the placement position of the second cooking container having a smaller diameter than the first cooking vessel is displayed on the second cooking container placed on the second heating zone portion. Heating is performed by a plurality of heating coils.

  According to this invention, the 2nd heating zone part which shows the mounting position of the 2nd cooking container whose diameter is smaller than the 1st cooking container is displayed in the 1st heating zone part, and the 2nd cooking container When cooking, the second cooking container is placed on the second heating zone and heated by a plurality of heating coils. Thereby, it heats from the part which opposes a some heating coil among the bottoms of a 2nd cooking container, For this reason, the content of a 2nd cooking container can be convected and the 2nd cooking container is heated. It is possible to suppress bumping that tends to occur.

2 is a plan view showing a display example of the right heating zone portion of the top plate, the configuration of the right heating coil, and the arrangement of the temperature sensor in the cooking device of FIG.

  The right heating coil 23 disposed under the right heating zone section 5 includes a circular inner heating coil 23a and a ring-shaped outer heating coil 23b surrounding the outer periphery of the inner heating coil 23a with a gap. ing. The right heating zone section 5 has a diameter corresponding to a normal-sized pan 50 (first cooking container, see FIG. 3). In the right heating zone section 5, when the top plate 2 is viewed from above, a heating zone section 5 a (second heating zone section) for a small pan is placed at a position straddling a part of the inner heating coil 23 a and the outer heating coil 23 b. Is displayed. In addition, the white circle of FIG. 2 has shown the heating surface of the pan bottom of the small pan 50a.

  For example, two thermistors 21a and 21b (first 2 temperature sensors). In addition, an infrared sensor 22 (first temperature sensor) is installed in a gap between the inner heating coil 23a and the outer heating coil 23b and located in the center of the heating zone portion 5a for the small pan. The thermistors 21a and 21b are provided in contact with the lower surface of the top plate 2, and the infrared sensor 22 is installed below the top plate 2 (see FIG. 3).

  In addition, although the thermistors 21a and 21b are two, one may be sufficient. Further, a thermistor may be used in place of the infrared sensor 22.

Next, the circuit configuration on the right heating coil 23 side will be described with reference to FIG.
FIG. 3 is a block diagram showing a circuit configuration of the cooking device according to Embodiment 1 of the present invention.
The thermistors 21 a and 21 b generate a signal (for example, voltage) according to the heat transmitted from the small pot 50 a to the top plate 2 and input it to the temperature detection circuit 25. The infrared sensor 22 generates a signal (for example, a voltage) based on the amount of infrared rays emitted from the top 2 and inputs the signal to the temperature detection circuit 25. The temperature detection circuit 25 detects the temperature of the small pot 50 a based on signals from the thermistors 21 a and 21 b and inputs the temperature to the control circuit 27. Further, the temperature detection circuit 25 detects the temperature of the small pot 50 a based on the signal from the infrared sensor 22 and inputs it to the control circuit 27.

  The inverter circuit 24a converts DC power into high-frequency power based on the input of the drive signal (PWM) from the control circuit 27, and supplies it to the inner heating coil 23a. Similarly to the above, the inverter circuit 24b converts DC power into high-frequency power based on the input of the drive signal from the control circuit 27, and supplies it to the external heating coil 23b.

  When the thermal power (set thermal power) set by the upper surface operation unit 7 or the front operational unit 12 is input, the control circuit 27 generates a drive signal based on the set thermal power, and the inverter circuits 24a and 24b are activated by the drive signal. To drive. Further, the control circuit 27 generates a drive signal so that the set thermal power and the output power (thermal power) of the inverter circuits 24a and 24b are substantially the same, and drives the inverter circuits 24a and 24b by the drive signal. Operations such as determination of whether the small pot 50a or the normal-sized pot 50 is performed by the control circuit 27, and determination of whether the small pot 50a is placed on the predetermined heating zone 5a will be described later.

The operation of the heating cooker 100 configured as described above will be described with reference to FIGS. 4 and 5.
FIG. 4 is a flowchart showing the operation of the heating cooker according to Embodiment 1 of the present invention, and FIG. 5 is a diagram showing temperature changes of the two thermistors and the infrared sensor when heating the small pan. In addition, (b) of FIG. 5 has shown the thermal power when detecting the presence or absence of a pan, and the thermal power when heating a small pan.
When the heating power of the right heating coil 23 is set by the upper surface operation unit 7 or the front operation unit 12, the control circuit 27 starts heating by the right heating coil 23 (S1). First, as shown in FIG. 5 (b), the control circuit 27 outputs a drive signal at which each heating power of the inner heating coil 23a and the outer heating coil 23b becomes 500 W for 2 seconds to output inverter circuits 24a, 24b. Is driven (S2). That is, an intermittent drive signal is output that is ON (output) for 2 seconds and OFF (stop) for 2 seconds. Whether or not 2 seconds have passed is determined from the time measured by the time measuring unit 26.

  Thereafter, the control circuit 27 determines whether or not each output power of the inner heating coil 23a and the outer heating coil 23b is within a range of 50W to 100W (S3). The control circuit 27 proceeds to S9 when each output power is not within the range of 50W to 100W, but when each output power is within the range of 50W to 100W, the small pot 50a is placed in the right heating zone section 5. The inverter circuits 24a and 24b are controlled so as to be heated by the heating power for the small pot 50a (S5).

  For example, when the heating power set by the upper surface operating unit 7 or the front operating unit 12 is 2000 W, as shown in FIG. 5 (b), the inverter 50 a is heated so that the small pot 50 a is heated by the 1/2 1000 W heating power. The circuits 24a and 24b are controlled. In addition, although the thermal power of the small pot 50a was made into 1/2 of setting thermal power, this is an example and is not limited. Alternatively, the thermal power of the small pot 50a may be set in advance according to the cooking menu, and the inverter circuits 24a and 24b may be controlled so that the small pot 50a is heated with the thermal power according to the selection of the cooking menu.

  Thereafter, the control circuit 27 reads the temperature (thermistor temperature) detected by the thermistors 21a and 21b and the temperature (IR temperature) detected by the infrared sensor 22 from the temperature detection circuit 25, and (IR temperature) − (thermistor temperature). ) It is determined whether or not ≧ 100 ° C. (S6). The thermistor temperature to be subtracted from (IR temperature) selects the higher one of the two thermistors 21a and 21b.

  When the small pot 50a is placed in the heating zone 5a, the IR temperature of the infrared sensor 22 is higher than the thermistor temperatures detected by the thermistors 21a and 21b, respectively, as shown in FIG. (IR temperature) − (thermistor temperature) ≧ 100 ° C. In that case, the control circuit 27 enters the next process (S13) assuming that the small pot 50a is placed in the heating zone section 5a (S7). In this case, the control circuit 27 controls the inverter circuits 24a and 24b so that the small pot 50a is continuously heated at 1000W. At this time, it heats from the part which opposes the inner heating coil 23a and the outer heating coil 23b among the pot bottoms of the small pot 50a, and the contents of the small pot 50a convect inwardly. When receiving a stop instruction from the front operation unit 12, the control circuit 27 ends the heating operation of the small pot 50a.

  Further, when the small pot 50a is not placed in the heating zone portion 5a, for example, when the small pot 50a is positioned on one of the thermistors 21a and 21b, the change in the IR temperature is low and the thermistor temperature below the small pot 50a. Therefore, the thermistor temperature becomes higher than the IR temperature, and (IR temperature) − (thermistor temperature) ≧ 100 ° C. does not occur. Further, when the small pan 50a is not installed on any of the infrared sensor 22 and the thermistors 21a and 21b, the change in both the IR temperature and the thermistor temperature is low, so the temperature difference between the IR temperature and the thermistor temperature is small. , (IR temperature) − (thermistor temperature) ≧ 100 ° C.

  In this case, the control circuit 27 enters the next process (S13) assuming that the small pot 50a is not placed in the heating zone 5a (S8). In this case, the control circuit 27 notifies, for example, with a buzzer that the small pot 50a is not placed in the heating zone 5a, and ends the heating of the small pot 50a.

  In S3, when each output power is not within the range of 50W to 100W, the control circuit 27 determines whether the sum of the output power of the inner heating coil 23a and the output power of the outer heating coil 23b is less than 100W. (S9). When the total is less than 100 W, the control circuit 27 assumes that neither the normal-sized pot 50 or the small pot 50a is placed in the right heating zone section 5 (S10), and enters the next process (S13). In this case, the control circuit 27 notifies a buzzer that there is no pan in the right heating zone section 5 and ends the heating operation.

  In S9, when the total of the output power of the inner heating coil 23a and the output power of the outer heating coil 23b exceeds 100W, the control circuit 27 places the normal-sized pan 50 on the right heating zone section 5. (S11), the inverter circuits 24a and 24b are controlled so that the pan 50 is heated by the heating power set by the upper surface operation unit 7 or the front operation unit 12 (S12). Then, the control circuit 27 enters the next process (S13). In this case, for example, when the control circuit 27 controls the inverter circuits 24a and 24b so that the pot 50 is continuously heated with the set heating power, and receives a stop instruction from the front operation unit 12, the normal size The heating operation of the pot 50 is finished.

  As described above, according to the first embodiment, the heating zone portion 5a for the small pan is displayed in the right heating zone portion 5 at a position straddling a part of the inner heating coil 23a and the outer heating coil 23b. When cooking, the small pot 50a is mounted in the heating zone part 5a, and it heats with the inner heating coil 23a and the outer heating coil 23b. Thereby, it heats from the part facing two heating coils 23a and 23b among the pot bottoms of the small pot 50a, Therefore The contents of the small pot 50a can be convected inward, and it is easy to generate | occur | produce at the time of the heating of the small pot 50a. Bumping can be suppressed.

  Further, when (IR temperature) − (thermistor temperature) ≧ 100 ° C., it is assumed that the small pot 50a is placed in the heating zone 5a, and the heating of the small pot 50a is continued. (IR temperature) − (thermistor temperature) When it is not ≧ 100 ° C., the heating of the small pot 50a is finished. Thus, since the heating of the small pot 50a is continued only when the small pot 50a is placed in the heating zone portion 5a, bumping that easily occurs during the heating of the small pot 50a can be reliably suppressed.
