  Conventionally, as a cooking device, there is one that can change the rated power in accordance with the power environment (see, for example, JP-A-2005-76997 (Patent Document 1)).

  As with such cooking devices, in microwave ovens that cook using microwaves, the input power (input current) increases as the microwave output increases. Therefore, there is a need for a usage method that reduces peak power.

  When the microwave oven is used with a low input power, it is necessary to set the microwave output low in the manual heating operation for setting the microwave output and the heating time.

  However, in the above microwave oven, in the heating operation of the automatic menu in which the microwave output and the heating time are set in advance, a high output is set against the user's will, and thus there is a problem that the peak power cannot be suppressed. is there. In addition to the background of the macro power situation, there is a problem that the breaker is shut off due to an overcurrent exceeding the current capacity in a state where a plurality of home kitchen devices are used.

  The input operation unit is not limited to this, and may be a touch panel having a display function.

  In this heating cooker, a heating chamber 10 whose opening 10 a is opened and closed by a door 2 is arranged in the casing 1. And the turntable 11 which rotates the to-be-heated material mounted in the bottom part in the heating chamber 10 is arrange | positioned. In addition, a heater 21 (shown in FIG. 2) for heating the object to be heated is disposed in the upper part of the heating chamber 10, and the object to be heated is heated in the casing 1 and to the side of the heating chamber 10. A magnetron 22 (shown in FIG. 2) as an example of a microwave generating unit that generates the microwave is disposed.

  FIG. 2 shows a control block diagram of the cooking device.

  As shown in FIG. 2, the heating cooker includes a control device 20 including a microcomputer and an input / output circuit. The control device 20 is connected to a heater 21, a magnetron 22, a turntable motor 23, a display unit 6, an input operation unit 7, and an internal temperature sensor 12. Based on the signal from the input operation unit 7 and the detection signal from the internal temperature sensor 12, the control device 20 controls the heater 21, magnetron 22, turntable motor 23, and the like.

  The input operation unit 7 has an output upper limit value setting key 8 for setting the output upper limit value of the microwave output. The output upper limit value setting key 8 may set an output upper limit value with a single key, or may set an output upper limit value with a combination of a plurality of keys.

  The control device 20 includes an output upper limit value setting means 20a for setting the output upper limit value of the microwave output of the magnetron 22, a microwave control means 20b for controlling the magnetron 22, and an automatic menu heating operation for performing an automatic menu heating operation. Operation control means 20c, automatic menu heating time correction means 20d for correcting the heating time of the automatic menu, non-volatile memory 20e for storing the output upper limit value of the microwave output, and the output value and heating of the magnetron 22 for manual heating Manual heating setting means 20f for setting the time, manual heating time correction means 20g for correcting the heating time set by the manual heating setting means 20f according to the output upper limit value, and manual heating operation control for performing the manual heating operation Means 20h for setting the time zone for limiting the microwave output Has a between range setting means 20i, the timing means 20j for measuring time.

  Next, the operation of the control device 20 will be described below in accordance with the flowcharts shown in FIGS.

First, when the heating cooker is turned on, the output upper limit value P _MAX of the microwave output stored in the nonvolatile memory 20e is read in step S1. The output upper limit value P _MAX is initially set to the maximum value (for example, 1000 W) of the microwave output of the magnetron 22.

Next, the process proceeds to step S2, and if it is determined that the output upper limit value has been input by the user using the output upper limit value setting key 8 on the operation panel 5, the process proceeds to step S3, where the output upper limit value setting means 20a uses the micro of the magnetron 22. The output upper limit value P _MAX of the wave output is set to the changed value.

Next, the process proceeds to step S4, where the output upper limit value P _MAX set by the output upper limit value setting means 20a is stored in the nonvolatile memory 20e, and the process proceeds to step S5.

  On the other hand, if it determines with the output upper limit being not input by step S2, it will progress to step S5.

  Next, if it is determined in step S5 that the user has selected the manual heating operation by the input operation unit 7, the process proceeds to step S11 shown in FIG. 4, while the input operation unit 7 determines that the user has not selected the manual heating operation. Then, it progresses to step S6.

  Next, in step S6, if it is determined by the input operation unit 7 that the user has selected the automatic menu heating operation, the process proceeds to step S21 shown in FIG. 5, while the user has selected the automatic menu heating operation by the input operation unit 7. If it is determined that there is not, the process proceeds to step S7.

  Next, if it is determined in step S7 that the user operates the input operation unit 7 and the time zone W has been input, the process proceeds to step S8, whereas if it is determined that the time zone W has not been input, the process returns to step S2.

  In step S8, the input time zone W is set (or changed) by the time zone setting means 20i.

[Manual heating operation]
Next, in step S11 shown in FIG. 4, the user operates the input operation unit 7, and the output value P1 of the microwave output in the manual heating operation is set by the manual heating setting means 20f.

  Next, it progresses to step S12 and a user operates the input operation part 7, and sets the heating time T1 in manual heating operation by the manual heating setting means 20f.

Next, the process proceeds to step S13, and if it is determined that the set microwave output value P1 is larger than the output upper limit value P _MAX , the process proceeds to step S14, while the set microwave output value P1 is the output upper limit value. If it is determined that the value is less than or equal to the value P _MAX , the process proceeds to step S17.

In step S14, if it is determined that the current time of the time measuring means 20j is included in the time zone W, the process proceeds to step S15. On the other hand, if it is determined that the current time of the time measuring means 20j is not included in the time zone W, step S17 is performed. Proceed to In addition, by setting 25:00 to 25:00 or the like in the time zone W, it is possible not to be limited by the output upper limit value P _MAX of the microwave output depending on the time zone.

Next, in step S15, the output value P1 is set as the output upper limit value P _MAX .

Next, proceeding to step S16, the heating time T1 is corrected by the manual heating time correction means 20g. Here, the correction of the heating time T1 by the manual heating time correction means 20g is, for example, when a microwave output of 1000 W and a heating time of 120 seconds are set, assuming that the output upper limit value P _MAX is 500 W, the heating time T1 is Is obtained by the following equation.
T1 = T1 × P1 / P _MAX + α
= 120 seconds x 1000W / 500W + α
= 240 seconds + α

Here, α is a correction value applied when the difference between the output value P1 and the output upper limit value P _MAX is large and the corrected heating time T1 is long. This is because if the microwave output is reduced and the heating time is further increased, the influence of heat radiation increases, so that the cooking finish is made similar by increasing the heating time.

Specifically, when the difference between the output value P1 and the output upper limit value P _MAX is equal to or greater than the threshold value Pa and the corrected heating time T1 is equal to or greater than the threshold value Ta, the calculated correction value α is added according to the corrected heating time T1. When the difference between the output value P1 and the output upper limit value P _MAX is less than the threshold value Pa or the corrected heating time T1 is less than the threshold value Ta, the correction value α = 0. The calculation method of the correction value α according to the corrected heating time T1 is performed using an equation or a table created based on an experiment or the like.

When the microwave output 300W and the heating time 45 seconds are set, the output value P1 of the set microwave output and the heating time T1 are given priority as they are without being limited by the output upper limit value P _MAX. It can cope with cooking such as melting butter with wave output.

Next, when it is determined in step S17 that the user presses the start button to start the manual heating operation, the process proceeds to step S19, where manual heating operation processing is performed by the manual heating operation control means 20h, and then shown in FIG. Return to step S2. In this manual heating operation process, the magnetron 22 is controlled by the microwave control means 20b under the condition of the output value P1 (≦ output upper limit value P _MAX ) or the output upper limit value P _MAX (≦ output value P1) and the heating time T1. Since the heating operation is performed, the microwave output of the magnetron 22 does not exceed the output upper limit value P _MAX .

  On the other hand, if it is determined in step S17 that the manual heating operation is not started, the process proceeds to step S18 to determine whether or not the manual heating operation is cancelled.

  If it is determined in step S18 that the manual heating operation is cancelled, the process returns to step S2 shown in FIG. 3, while if it is determined that the manual heating operation is not canceled, the process returns to step S17.

[Automatic menu heating operation]
Next, in step S21 shown in FIG. 5, a desired automatic menu is selected from a plurality of automatic menus. For example, as an automatic menu, there is one stage heating for heating rice (for one cup) with a microwave output of 1000 W and a heating time of 30 seconds.

  Next, the process proceeds to step S22, and if it is determined that the selected automatic menu is two-stage heating, the process proceeds to step S31 shown in FIG. 6, while the selected automatic menu is not two-stage heating, that is, one-stage heating. If it determines, it will progress to step S23. Here, the two-stage heating is an automatic menu for continuously performing two-stage heating processes with different microwave outputs and heating times.

Automatic first stage heating Next, in step S23, if it is determined that the output value P1 of the microwave output of the automatic menu 1 stage heating which is selected is greater than the output upper limit value P _MAX, the process proceeds to step S24, the selected If it is determined that the output value P1 of the microwave output of the menu is equal to or lower than the output upper limit value P _MAX , the process proceeds to step S27.

  In step S24, if it is determined that the current time of the time measuring means 20j is included in the time zone W, the process proceeds to step S25, while if it is determined that the current time of the time measuring means 20j is not included in the time zone W, step S27 is performed. Proceed to

Next, in step S25, the output value P1 is set as the output upper limit value P _MAX .

In step S26, the automatic menu heating time correction unit 20d corrects the heating time T1 of the selected automatic menu. Here, the correction of the heating time T1 by the automatic menu heating time correction means 20d is, for example, when an automatic menu (microwave output 1000 W, heating time 30 seconds) for heating rice (one cup) is selected. Assuming that P _MAX is 500 W, the heating time T1 is obtained by the following equation.
T1 = T1 × P1 / P _MAX + α
= 30 seconds x 1000W / 500W + α
= 60 seconds + α

Here, α is a correction value applied when the difference between the output value P1 and the output upper limit value P _MAX is large and the corrected heating time T1 is long. This is because if the microwave output is reduced and the heating time is further increased, the influence of heat radiation increases, so that the heating time needs to be increased.

Specifically, when the difference between the output value P1 and the output upper limit value P _MAX is equal to or greater than the threshold value Pa and the corrected heating time T1 is equal to or greater than the threshold value Ta, the calculated correction value α is added according to the corrected heating time T1. When the difference between the output value P1 and the output upper limit value P _MAX is less than the threshold value Pa or the corrected heating time T1 is less than the threshold value Ta, the correction value α = 0. The calculation method of the correction value α according to the corrected heating time T1 is performed using an equation or a table created based on an experiment or the like.

  Next, when it is determined in step S27 that the start button is pressed by the user to start the automatic menu heating operation, the process proceeds to step S29, and automatic menu heating operation processing (one stage heating) is performed by the automatic menu heating operation control means 20c. After that, the process returns to step S2 shown in FIG.

In this automatic menu heating operation process, in the time zone W, the magnetron is controlled by the microwave control means 20b under the conditions of the output value P1 (≦ output upper limit value P _MAX ) or the output upper limit value P _MAX (≦ output value P1) and the heating time T1. Therefore, the microwave output of the magnetron 22 does not exceed the output upper limit value P _MAX .

  On the other hand, if it is determined in step S27 that the automatic menu heating operation is not started, the process proceeds to step S28 to determine whether or not the automatic menu heating operation is cancelled.

  If it is determined in step S28 that the user has performed a cancel operation to cancel the automatic menu heating operation, the process returns to step S2 shown in FIG. 3, while if it is determined not to cancel the automatic menu heating operation, the process proceeds to step S27. Return.

2-stage heating Next, in step S31 shown in FIG. 6, if it is determined that the output value P1 of the microwave output of the automatic menu of the first stage which is selected is greater than the output upper limit value P _MAX, the process proceeds to step S32, If it is determined that the output value P1 of the microwave output of the first stage automatic menu is equal to or less than the output upper limit value P _MAX , the process proceeds to step S35.

  In step S32, if it is determined that the current time of the time measuring means 20j is included in the time zone W, the process proceeds to step S33, while if it is determined that the current time of the time measuring means 20j is not included in the time zone W, step S35 is performed. Proceed to

Next, in step S33, the output value P1 is set as the output upper limit value P _MAX .

  In step S34, the automatic menu heating time correction means 20d corrects the heating time T1 of the first stage automatic menu.

Here, the correction of the heating time T1 by the automatic menu heating time correction means 20d is, for example, when the first stage condition is a microwave output of 1000 W and a heating time of 120 seconds, and the output upper limit value P _MAX is 500 W. The heating time T1 is obtained by the following equation.
T1 = T1 × P1 / P _MAX + α
= 120 seconds x 1000W / 500W + α
= 240 seconds + α

Here, α is a correction value applied when the difference between the output value P1 and the output upper limit value P _MAX is large and the corrected heating time T1 is long. This is because if the microwave output is reduced and the heating time is further increased, the influence of heat radiation increases, so that the heating time needs to be increased.

Specifically, when the difference between the output value P1 and the output upper limit value P _MAX is equal to or greater than the threshold value Pa and the corrected heating time T1 is equal to or greater than the threshold value Ta, the calculated correction value α is added according to the corrected heating time T1. When the difference between the output value P1 and the output upper limit value P _MAX is less than the threshold value Pa or the corrected heating time T1 is less than the threshold value Ta, the correction value α = 0. The calculation method of the correction value α according to the corrected heating time T1 is performed using an equation or a table created based on an experiment or the like.

Next, the process proceeds to step S35, and if it is determined that the output value P2 of the microwave output of the selected second stage automatic menu is larger than the output upper limit value P _MAX , the process proceeds to step S36 while the second stage automatic menu is selected. If it is determined that the output value P2 of the microwave output is equal to or less than the output upper limit value P _MAX , the process proceeds to step S41 shown in FIG.

  Next, in step S36, if it is determined that the current time of the time measuring means 20j is included in the time zone W, the process proceeds to step S37, while if it is determined that the current time of the time measuring means 20j is not included in the time zone W, FIG. The process proceeds to step S41 shown in FIG.

Next, in step S37, the output value P2 is set as the output upper limit value P _MAX .

  Next, proceeding to step S38, the heating time T2 of the automatic menu of the second stage is corrected by the automatic menu heating time correcting means 20d, and the process proceeds to step S41 shown in FIG.

  Here, the correction of the heating time T2 by the automatic menu heating time correction means 20d is performed in the same manner as the correction of the heating time T1 of the first stage.

  Next, when it is determined in step S41 shown in FIG. 7 that the start button is pressed by the user to start the automatic menu heating operation, the process proceeds to step S43, and the automatic menu heating operation control means 20c performs automatic menu heating operation processing (2 After performing (stage heating), it returns to step S2 shown in FIG.

In this automatic menu heating operation process, in the time zone W, the output value P1 (≦ output upper limit value P _MAX ) or the output upper limit value P _MAX (≦ output value P1), the condition of the first stage of the heating time T1, and the output value Since the microwave control unit 20b controls the magnetron 22 to perform heating operation under the condition of P2 (≦ output upper limit value P _MAX ) or output upper limit value P _MAX (≦ output value P2) and the second stage of the heating time T2. The microwave output of the magnetron 22 does not exceed the output upper limit value P _MAX .

  On the other hand, if it is determined in step S41 that the automatic menu heating operation is not started, the process proceeds to step S42 to determine whether or not the automatic menu heating operation is cancelled.

  If it is determined in step S42 that the cancel operation has been performed by the user and the automatic menu heating operation is cancelled, the process returns to step S2 shown in FIG. 3, while if it is determined not to cancel the automatic menu heating operation, the process proceeds to step S41. Return.

According to the cooking device having the above-described configuration, the output upper limit value setting unit 20a sets the output upper limit value P _MAX smaller than the maximum value of the microwave output of the magnetron 22, thereby allowing the microwave to cover the inside of the heating chamber 10. Since the microwave control means 20b controls the magnetron 22 so that the microwave output of the magnetron 22 does not exceed the output upper limit value P _MAX when heating the heated object, the power consumption can be suppressed, and the peak power can be reduced from the power situation. It is possible to reduce power consumption and to cope with a power supply environment in which current capacity is insufficient at the maximum output of microwaves.

Further, the automatic menu heating operation control means 20c automatically selects an automatic menu for which the output value of the magnetron 22 among the plurality of automatic menus exceeds the output upper limit value P _MAX set by the output upper limit value setting means 20a. Since the magnetron 22 is controlled so that the microwave output of the magnetron 22 becomes the output upper limit value P _MAX during the menu heating operation, power consumption can be suppressed even in a plurality of preset automatic menus.

Further, the automatic menu heating operation control means 20c is an automatic menu output values of the magnetron 22 of the plurality of automatic menus exceeds the output upper limit value P _MAX, the output upper limit value P _MAX and automatic menu heating time correcting means 20d Since the automatic menu heating operation is performed by controlling the magnetron 22 under the corrected heating time T1, the heating conditions set in the automatic menu while suppressing power consumption even in a plurality of preset automatic menus. It is possible to realize a cooking finish equivalent to the heating operation performed at (microwave output value and heating time).

Further, the microwave control means 20b controls the magnetron 22 so that the microwave output of the magnetron 22 does not exceed the output upper limit value P _MAX stored in the nonvolatile memory 20e, so that the output is performed every time the power is turned on / off. without setting an output upper limit value P _MAX by upper limit setting unit 20a, available output upper limit value P _MAX stored in the nonvolatile memory 20e, thereby improving the user experience.

In addition, since the output upper limit value P _MAX is set by the output upper limit value setting key 8 of the input operation unit 7 by the output upper limit setting means 20a, the operability is improved by the dedicated key and the convenience of the user can be improved.

Also, the when the output value P1 of the manual heating setting section 20f magnetron 22 set by is greater than the output upper limit value P _MAX is the output upper limit value P _MAX and manual heating time correction means heating time which has been corrected by 20 g T1 Since the manual heating operation is performed by controlling the magnetron 22 by the manual heating operation control means 20h under the conditions, the recommended microwave output and heating time of the food to be heated can be set as it is by the manual heating setting means 20f. The heating time corresponding to the microwave output of the magnetron 22 may not be converted by the user himself during manual heating.

Further, in the time zone W set by the time zone setting means 20i, the magnetron 22 is controlled by the microwave control means 20b so that the microwave output of the magnetron 22 does not exceed the output upper limit value P _MAX. The time zone which suppresses power consumption according to can be set.

  The time zone W can be set by inputting two start times and end times using the input operation unit 7 or by setting a plurality of preset time zone patterns (from 9:00 am to 24 pm, where power peaks are likely to occur). Or from 13:00 pm to 16:00 pm).

  Conventionally, in developing countries where power supply conditions are poor, it is difficult to heat at high output, and there are differences depending on the region, so a cooking device having a low microwave output as a maximum output value has been shipped.

  On the other hand, according to the heating cooker of the present invention, for example, a user who uses a heating cooker with a low microwave output in an area where the power supply situation is bad is like an emerging residential area from an area where the power supply situation is bad When moving to a new area, the heating cooker is provided with a means that can be changed so that heating can be performed at a higher output than the current level, so that heating at a higher output is possible without the need for a new replacement.
