  However, in the conventional power control system, when the induction heating cooker (hereinafter referred to as IH cooking heater) uses a plurality of heating ports as a method of reducing the power of the IH cooking heater in order to prevent the breaker from falling, It has not been clarified whether to select a certain amount of heating ports at a uniform rate or to select a heating port with a reduced priority.

  According to the present invention, the cooking device includes a power adjustment unit, and when the power adjustment request signal is received, by adjusting the usage power from the heating cooking unit that uses a large amount of power, the user-friendliness is not impaired and the user is not impaired. It is an object of the present invention to provide a heating cooker, a heating cooker control method, and a program that reduce power consumption and prevent breaker breakage.

  In order to solve the conventional problem, first heating cooking means and second heating cooking means for heating a cooked item, mode setting means for setting a heating mode of the first heating cooking means and the second heating cooking means, Receiving means for receiving a power adjustment request signal transmitted from the power control device; and power adjusting means for adjusting the used power from the heating cooking means having a larger power consumption when the receiving means receives the power adjustment request signal As a method of demand control to prevent dropping the breaker in the home, when using the heating cooker with multiple heating ports at the same time, heating using large electric power Since power is suppressed from the mouth, the inconvenience that cooking cannot be performed by avoiding stopping heating as much as possible is eliminated, and a certain amount of power reduction can be expected. It is possible to prevent the cut-off of over mosquitoes.

  The heating cooker, the heating cooker control method, and the program according to the present invention can be used by a user himself / herself in a case where the heating cooker is simultaneously used at a plurality of heating ports when there is not enough room in the household. Without powering down the heating power of the heating cooker, the power is automatically suppressed from the heating port that uses a large amount of power, so the user can avoid stopping the heating completely as much as possible. It is possible to continue cooking smoothly even when there is little room in the household power without impairing the convenience of use. Furthermore, since power is reduced from the larger heating port, a certain amount of power reduction can be expected, and breaker breakage can be prevented.

  In addition, the power controller side does not need to be aware of the setting state such as the operation mode on the device side or the power consumption state, and simply sends the necessary reduced power to the device, and the device side performs complex control processing. Even if it is not necessary, the power can be suppressed in accordance with the received power reduction request, so that a complicated information processing function is not required, so that a system can be constructed at low cost.

The first invention is the first heating cooking means and the second heating cooking means for heating the food, the mode setting means for setting the heating mode of the first heating cooking means and the second heating cooking means, and the first A power calculation means for calculating the power consumption of the heating cooking means and the second heat cooking means, and a power reduction request signal for requesting that the power consumption be reduced below the power consumption calculated by the power calculation means, or Receiving means for receiving a power reduction cancellation signal from an external power control device that requests to use more power than the amount of power used by the power calculating means, and receiving the power reduction request signal by the receiving means If the power consumption reduction amount is determined from the heating cooking means with the larger power consumption, the power consumption adjustment amount is determined from the reduced heating cooking means when the power reduction cancellation signal is received by the receiving means. And an adjustment amount determining means, said mode setting means can be set in a heating mode, the first cooking unit or the second cooking unit does not change the heating temperature level during the heating the food manual system mode And an automatic cooking system mode that automatically changes the heating temperature level during heating of the first heating cooking means or the second heating cooking means, and is provided to the first heating cooking means or the second heating cooking means The manual system mode is a heating cooker that determines a power consumption adjustment amount preferentially over the automatic cooking system mode when a power reduction cancellation signal is received by the receiving means , and has room for power in the home. When the cooker is used at the same time with multiple heating ports, the user automatically uses large power without having to operate the cooker quickly to lower the heating power of the cooker. Since the power is controlled from the heating port, it is possible to continue cooking smoothly even when there is little room in the household power without damaging the user's convenience by avoiding stopping heating as much as possible. Can do. In addition, since power is reduced from the larger heating port, a certain amount of power reduction can be expected, and the breaker can be prevented from being interrupted. It is not necessary to be conscious of it, it is complicated because the device only needs to adjust the output power according to the received power adjustment request contents without sending complicated control processing by simply transmitting the power adjustment request signal to the device. Since a simple information processing function is not required, a system can be constructed at low cost. In addition, when there is enough power in the home after the heating cooker has been adjusted for power, a power reduction cancellation signal is received from the power control device, and the amount of power used is adjusted from the heating cooking means with the larger power reduction By determining, usability can be improved.

Et al. Is, by increasing the resolving priority of the manual system mode than automatic cooking system mode, such as when you want to be heated quickly with a weak thermal power, if the available power, even a little, to make it possible to use, user It is possible to prevent a decrease in convenience.

If the power consumption adjustment amount determined when receiving the power reduction cancellation signal is greater than 0, it is provided with a notification means for performing notification, and the power adjustment after the power adjustment in the home has no margin. The user can know by the notification means that the state can be resolved. Note that if output power is automatically restored, spilling or bumping may occur depending on the heating condition, so the output power is not automatically restored, but the user is informed and operated by the user himself / herself. Safety can be ensured by returning to.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a system configuration diagram of a power control system of the present invention, and FIG. 2 is a block diagram of a power control device and an IH cooking heater of the power control system.

  In the first embodiment of the present invention, the current clamp 2 is sandwiched between the power lines on the input side of the distribution board 1 that draws the single-phase three-wire type 200V into the home, and the input currents L1 and L2 are supplied to the power control device 3. Measure with In the distribution board, there is a breaker (not shown) that cuts off the supply of power when the rated current is exceeded. The breaker is a type that shuts off when the current value of one phase of the L1 phase or L2 phase flows over a predetermined value, or shuts down when the total current value of both the L1 and L2 phases flows over a predetermined value In the present embodiment, a description will be given assuming a breaker of a type that shuts off when a current value that is a sum of both the L1 phase and the L2 phase flows over a predetermined value.

  Also, on the output line of the distribution board, IH cooking heater 4 as AC200V system, AC5V system, one adapter 5a connected to air conditioner 7a in L1 phase, one dryer 8 and air conditioner 7b connected to L2 phase It is assumed that one adapter 5b is connected. The power control device 3, the IH cooking heater 4, and the adapters 5a and 5b incorporate a wireless communication device 6 and can transmit information. As a wireless communication method, communication is performed using a specific low-power wireless and a transmission frequency of 400 MHz band.

  The device unit 9 includes the wireless communication device 6 and can intercept wireless communication data transmitted in a space within the same system, and can collect information on each device. In addition, this is a unit that can be built at low cost because it has a Web server installed therein as software and does not have display means for displaying characters and images.

  The device unit 9 and the television 10 are connected via a hub 201 via a general-purpose network. The television 10 is provided with a web browser, and the device unit 9 is displayed on the screen using a web browser of a device having a web client function such as the television 10 or a personal computer (not shown) via a general-purpose network. You can browse the information collected in.

  The general-purpose network is not particularly specified physically, and may be anything as long as it is a network network that can transmit and receive using the HTTP protocol.

  The TV can be connected to the Internet via the modem / router 202.

  In an actual home, many other devices are connected. However, in order to simplify the description, the following description will be given as the above configuration.

  FIG. 2 is a block diagram of the power control device 3 and the IH cooking heater 4 of the power control system. The power control device 3 measures the current flowing through the L1-phase power system line of the single-phase three-wire system 200V. There are an L2 current detector 11b that measures the current flowing through the power supply system line of the unit 11a and the L2 phase, and a voltage detector 12 that measures the voltage of the L1 phase or the L2 phase, and the L1 current detector 11a and the L2 current detector 11b. Based on the current value and the voltage value measured by the voltage detection unit 12, the power calculation unit 13 calculates the power value. Note that the power is calculated such as an L1 phase input power value, an L2 phase input power value, and a total input power value of both phases L1 and L2.

  The control unit 14 performs arithmetic processing on the input information and data, and generates and sends out control signals and data.

  The current upper limit setting unit 15 sets an upper limit value of the current value flowing in the L1 phase and the L2 phase. The upper limit value is set in advance as an initial value, and if a change is necessary, an input means such as a switch or an external terminal may be attached so that it can be set from a dedicated terminal or a personal computer. In this embodiment, the initial value = 30 A is used. Here, when the total current value of both phases flowing in the L1 phase and the L2 phase exceeds the set upper limit value, an instruction is given to the device to reduce the power. In addition, after the power reduction, if the total current value of the L1 phase and the L2 phase is 90% or less of the upper limit value, an instruction to suppress the power reduction is given to the device that has reduced the power because the power is available. I will put it out. Note that the numerical value of 90% of the upper limit value is an example of a numerical value that takes hysteresis into consideration so as not to frequently reduce power to the device.

  The priority setting unit 16 determines the use priority of the device. For example, the priority is set by the user by providing a dip switch on the device side, and when the device is turned on or when the setting is switched, the priority information is transmitted to the power control device 3 and the power is set. The control device 3 receives the priority information from the device, sets and grasps the priority of the device by the priority setting unit 16, and updates the priority information of the data managed by the management unit 18. As another method, the priority setting screen is displayed on the TV screen using the device unit 9 and the TV 10, and the priority of the device connected using the TV remote control is displayed on the TV screen. The user may be able to set freely.

  The management unit 18 manages setting values and states such as the above-described priority information, device power consumption information, and device power suppression control status as data, and information other than the device power consumption information is stored in a nonvolatile memory such as an EEPROM. The data is stored in the memory so that the data is not erased even when the power is cut off.

  The available power notification unit 19 calculates the difference between the current upper limit value set by the current upper limit value setting unit 15 and the current value measured by the L1 current detection unit 11a or the L2 current detection unit 11b, and an inquiry from the device, Information including a usable power value based on the difference is transmitted to the device whose power is suppressed as a usable power notification signal. That is, when the device side receives the usable power notification signal, it means that the device can be further used if the power is within the usable power value. In particular, when there is a device whose power is suppressed, an available power notification signal is transmitted when it becomes 90% or less of the upper limit set by the current upper limit setting unit 15.

  When the current value measured by the L1 current detection unit 11a or the L2 current detection unit 11b exceeds the current upper limit value set by the current upper limit value setting unit 15, the reduction power request unit 20 causes the breaker of the distribution board to drop. Since there is a possibility, the reduced power request signal is transmitted with the excess amount as the reduced power value so as to reduce the power consumption to the device side. That is, when the device side receives the reduced power request signal, it reduces the power used.

  The transmission / reception unit 21 transmits / receives data via the communication network unit 50 that performs wireless communication.

  The notification unit 22 notifies a warning or the like with sound using a buzzer, a speaker, or the like. The IH cooking heater 4 has four heating ports 41 and uses the functions of three IH coils 41a, 41b, 41c and one grill 41d, and the output level can be set stepwise on the IH coil. The user can select and use various functions such as “heating” of the manual system, “fried food”, and “heating cooking” of the automatic cooking system. The grill is controlled by a heater, and an automatic cooking system cooking mode (heating mode) using several kinds of sequence patterns such as “fish grill” and “gratin” can be selected. Note that the automatic cooking system cooks by automatically controlling the output power by using a cooking mode, temperature sensor, infrared sensor, etc. for a time determined by the sequence pattern of the relationship between time and output power. It is a convenient function that allows cooking to be performed by the device such as a cooking mode, and the manual system is a function that outputs a constant heating power (electric power) according to the selected heating level. The principle of heating the IH cooking heater is well known and will not be described and illustrated.

  The IH cooking heater 4 includes a current detection unit 31 that measures a current flowing through a 200 V single-phase power system line and a voltage detection unit 32 that measures a voltage. The current value measured by the current detection unit 31 and the voltage detection unit 32 Based on the voltage value, the power calculation unit 33 calculates the power usage value of the IH cooking heater 4.

  The control unit 34 performs arithmetic processing on the input information and data, and generates and sends out control signals and data.

  The operation unit 35 includes switches such as buttons for selecting functions such as “heating”, “fried food”, “heating cooking”, and “hot water” in each IH coil and grill of the IH cooking heater 4.

  The switch of the operation unit 35 may be an electrostatic switch, a tact switch, a touch panel, or the like. Further, the display unit 36 displays the mode display of the function selected by the operation unit 35, the operation state during the driving operation, and the like on the LED and the liquid crystal panel.

  The IH output power management unit 37 is a table showing required output power corresponding to each IH coil and grill heating mode (detailed description will be given later, but FIG. 5 shows a table example).

  The necessary power transmission unit 38 refers to the table of the IH output power management unit 37 for the contents operated by the user and inquires the power control device 3 about the necessary power.

  When the device output power determination unit 39 receives the inquiry result or the available power notification signal from the power control device 3, the table of the IH output power management unit 37 with respect to the available power value included in the received information. Is used to determine the heating mode of the maximum power within the usable power value, and output power control to each heating port for the heating mode determined by the IHCH control unit 40 via the control unit 34 is performed.

  Further, when the IH cooking heater 4 receives the power reduction request signal from the power control device 3, the IH cooking heater 4 refers to the table of the IH output power management unit 37, selects the heating mode to be reduced, and stores the table in the table until the power reduction value or more is reduced. Repeat the search.

  Next, the operation of reducing the power of the power control system of the present invention will be described with reference to the sequence diagram of FIG. 3, the flowchart of FIG. 4, and the data table of FIG.

  FIG. 3 is a sequence diagram illustrating an operation of reducing the power of each device when the power control apparatus detects power of a predetermined value or more.

  In FIG. 3, in the power control device 3, the sum of the current values detected by the control unit 14 by the L1 current detection unit 11 a and the L2 current detection unit 11 b is the current value set by the current upper limit value setting unit 15 (in the present embodiment). , 30A) is exceeded (S31), the notification unit 22 issues a warning notification by sound or display because the household power is excessively used (S32), and the reduced power request unit 20 sets the priority. The devices are selected in the order of the devices with the lowest priority set by the unit 16, and the power reduction request signal is transmitted from the transmission / reception unit 21 (S33). The information included in the power reduction request signal is a power value. For example, when the control unit 14 determines that the current value set by the current upper limit value setting unit 15 exceeds 5 A, the power value is converted to 500 W. Let (5A × 100V) be the power value for which reduction is requested. That is, the over-threshold value set by the current upper limit value setting unit 15 is converted into a power value and a reduction request is made. Here, in order to simplify the description, it is assumed that two devices, an IH cooking heater and an adapter (air conditioner connection), are present as devices that can be controlled, and that the IH cooking heater is set to have a higher priority than the adapter. .

  The adapter that has received the power reduction request signal turns off the air conditioner. The adapter may be turned off by a method of turning off the air conditioner by switching means such as a relay or by sending a remote control signal with a remote control light emitting element. Moreover, even if it is not OFF, electric power is reduced by changing an operation mode to a ventilation mode or reducing the rotation speed of a compressor.

  Further, the adapter responds with the power to be reduced (S35).

  The power control device 3 receives a response from the adapter by the transmission / reception unit 21, analyzes the received information by the control unit 14, and the reduction power value of the response from the adapter is less than the threshold value over (S 31) (S36), since the necessary power reduction is still insufficient, the power reduction requesting unit 20 sends the information power reduction request signal including the power value of the shortage to the next priority device (here, IH cooking heater). In response to this, a reduction request signal is transmitted from the transmitting / receiving unit 21 (S37). As a specific example, when a power reduction request signal of a reduction request 800W is transmitted in (S33), if a 500W reduction power response signal is returned as power that can be reduced by the adapter, a difference value of 300W (800W− 500 W) is transmitted to the IH cooking heater of the next priority.

  When the IH cooking heater receives the power reduction request signal at the transmission / reception unit 21, the control unit 34 analyzes the received information and performs power suppression control (S38). As a result, the reduced power value determined by the device output power determination unit 39 is obtained. A power reduction request signal is transmitted as a power response for reducing the information to be included (S39). The detailed operation of the power suppression control (S38) will be described later with reference to FIG.

  For example, if the power value is over 800W in (S31), a reduction of 800W is required. If the air conditioner connected to the adapter is operating at 500 W, even if the air conditioner is stopped, 300 W is insufficient, so a request for 300 W reduction is made to the IH cooking heater.

  Here, when the IH cooking heater uses a plurality of heating ports at the same time, the heating port used in the table shown in FIG. 5 and the power in the heating mode are reduced.

  FIG. 5 shows a data table managed by the IH output power management unit 37.

  “Heating mode” and “electric power” are provided for each heating port (left IH, right IH, rear IH, grill) of the IH cooking heater. “Heating mode” indicates a mode selected by the user on the operation panel. As a manual system, left IH and right IH are 10 levels (hereinafter referred to as L1 to L10) of levels 1 to 10, and later IH is 6 levels (hereinafter referred to as L1 to L6) from level 1 to level 6. It is possible to select a desired firepower. Moreover, as an automatic cooking system, fried food and cooked rice can be selected for the left IH and the right IH. In addition, the grill can be heated with a heater, and a menu of fish and gratin is prepared as an automatic cooking system.

  The item described as “power” indicates the output power of the IH or heater. In the automatic cooking system, the output power pattern is changed, and the maximum output power is described in a sequence performed in one cooking. In particular, after the heating mode of the automatic cooking system has been stopped due to power reduction, a usable power notification signal is not sent from the power control device 3 as a condition for returning again after the power control device 3 exceeds the maximum power value in the sequence. The breaker is prevented from falling by not allowing the automatic cooking operation.

  FIG. 4 is a flowchart showing an operation for reducing the power of the IH cooking heater. In FIG. 4, in order to simplify the description, the case where the first heating port (left IH) and the second heating port (right IH) are used at the same time will be described.

  First, the classification of the first heating port and the second heating port is examined. If only one of them is the manual system mode (S41), the heating port operating in the manual system is selected (S43c). That is, in the automatic cooking system, if an automatic cooking sequence such as rice cooking stops halfway, delicious rice may not be cooked, so the heating port used in the manual system is preferentially reduced in power.

  If both the first heating port and the second heating port are operating in the manual system, refer to the table in FIG. 5 and compare the output power of the two heating ports (S42). The larger heating port is selected (S43a) (S43b).

  After selecting the heating port whose power is to be reduced, the device output power determination unit 39 refers to the IH output power management unit 37 via the control unit 34 and calculates the power that can be reduced by reducing the level by one ( S44).

  If the reduction power more than the reduction required power cannot be secured (S45), the process returns to (S41) and the same process is repeated.

  In this way, the IH cooking heater can be used with confidence without dropping the breaker. Furthermore, automatic cooking does not stop, so it is very easy to use.

  If the control unit 34 determines that the power is reduced even a little (S46), the display unit 36 turns on the LED lamp to notify that the heating power (power) output in the heating mode selected by the user is suppressed. (S47) (Although, of course, notification by sound such as a buzzer may be used), the output of the thermal power (electric power) determined for each heating port by the device output power determination unit 39 is controlled. This is performed by the IHCH control unit 40 via the unit 34 (S48).

  Of course, although not shown in FIG. 2, not only the display unit as a notification method, but also notification by a buzzer, voice, etc. makes it easier for the user to notice that the power has been reduced. If the display shows which heating mode is controlled, the user knows the situation well and the breaker does not fall.

  In this way, when there is not enough room in the household, if the cooking device is used at the same time with a plurality of heating ports, the user himself / herself rushes to lower the heating power of the cooking device. Therefore, power is automatically suppressed from the heating port that uses a large amount of power, so avoiding stopping heating as much as possible without damaging the user's convenience and leaving room for household power. Even if there are few, cooking can be continued smoothly. Furthermore, to reduce the power from the larger heating port, a certain amount of power reduction can be expected, and the breaker can be prevented from being cut off. You don't need to be aware of the status, just send a power adjustment request signal to the device, and the device can adjust the output power according to the received power adjustment request, without complicated control processing. Since a complicated information processing function is unnecessary, a system can be constructed at a low cost.

  In addition, as shown in FIG. 5, since the automatic cooking system performs sequence control in which the output power is changed as a classification of the heating mode, and heating cooking stops, the cooking contents will be hindered, so power saving is necessary. In such a case, power is reduced by giving priority to the manual system. In particular, in the case of cooking rice, since it greatly affects the condition of rice brewing, the highest priority is set so that automatic cooking is not stopped as much as possible.

  Next, the operation of canceling the power reduction of the power control system of the present invention will be described with reference to the sequence diagram of FIG. 6, the flowchart of FIG. 7, and the data table of FIG.

  FIG. 6 is a sequence diagram showing an operation of canceling power reduction for a device that has been performing power reduction after the power control apparatus detects power equal to or lower than a predetermined value, and FIG. 7 cancels power reduction of the IH cooking heater. It is a flowchart which shows the operation | movement to do.

  In FIG. 6, in the power control device 3, the total current value detected by the L1 current detection unit 11 a or the L2 current detection unit 11 b based on the determination of the control unit 14 is the current value set by the current upper limit setting unit 15 (this embodiment) In this form, when it is reduced to 90% or less of 30A) (S61), the alarm notification is canceled by sound or display because the notification unit 22 has enough power in the home (S62). Then, the available power notification signal is transmitted from the transmission / reception unit 21 in the order of the devices with the higher priority set by the priority setting unit 16 (S63). Here, it is assumed that there are two IH cooking heaters and adapters (air conditioner connection) as devices that can be controlled, and the IH cooking heater has a higher priority than the adapter. A possible power notification signal is transmitted. The information included in the usable power notification signal is a power value. For example, the current detected by the L1 current detection unit 11a or the L2 current detection unit 11b with respect to the current value 30A set by the current upper limit setting unit 15 When the total value is 27% of 90%, the difference value 3A is converted into a power value, and 300W (3A × 100V) is set as the power value that can be used.

  When the IH cooking heater receives the available power notification signal by the transmission / reception 21, the control unit 34 analyzes the received information, performs the power suppression release process (S 64), and as a result, the usable device power determined by the device output power determination unit 39 can be used. An available power notification response signal is transmitted as a response indicating whether or not power suppression can be canceled for information including the power value (S65). The detailed operation of the power suppression release process (S64) will be described later with reference to FIG.

  When the IH cooking heater receives the available power notification signal, the IH cooking heater performs a power suppression release process. The power suppression release process will be described with reference to the flowchart of FIG.

  In FIG. 7, first, one heating port being reduced is selected (S71).

  Subsequently, the control unit 14 determines whether the heating mode classification of the selected heating port is a manual system or an automatic cooking system (S72), and if it is a manual system, the device output power determination unit 39 causes the control unit 34 to The IH output power management unit 37 is referred to, and the power value that is one level higher than the reduced level is referred to (S73). Subsequently, the difference value between the power value in the case of level up and the current reduced power value is calculated as the power difference value for the level up, and the available power received from the power control device 3 and the power difference for the level up If the values are compared (S74) and the available power is larger, it means that the heating mode of the selected heating port can be raised.

  If it is not a manual system in (S72), in the case of an automatic system, the power value shown in FIG. 5 is handled as a differential value for level up (S75).

  If the available power is smaller in (S74), it is determined that the heating port cannot be leveled up, and a search is made for other heating ports that are being reduced (S76). If there is a mouth, the heating mouth being reduced is selected (S77). Hereinafter, similarly, it is determined whether the level can be increased by the processing of (S72) to (S74).

  If there is no other device being reduced in (S76), the heating level of the IH cooking heater cannot be increased, and the power reduction state is continued.

  In (S74), if the available power is larger, the heating mode level of the selected heating port can be increased, so the notification during power reduction can be canceled and the heating level can be recovered even a little. In order to notify the user that the power has been reduced, a power reduction cancellation possible notification is performed (S78).

  In this way, the device output power determination unit 39 refers to the IH output power management unit 37 via the control unit 34, and changes the heating level in a direction in which each heating port increases even a little within the usable power value. I will determine if this is possible.

  As a notification method of the power reduction cancellation possible notification in (S78), notification is made by a method such as blinking the LED lamp on the display unit 36, or although not shown in FIG. In addition, when the user is notified by voice or voice, the user can easily notice that the power reduction can be canceled.

  Further, regarding the display, the user can further improve the usability by knowing which heating port can increase the power.

  It should be noted that the expressions (S73) and (S75) level up and automatic cooking ON are only for referring to the power value in the table, and are not reflected in the power output. If the heating power (power) is returned to the heating port once it has reduced power, it may cause spillage depending on the state before the power is reduced. When the user confirms and operates with a sound or a display that (power) can be raised, the level of the heating port that has been reduced in power is increased or automatic cooking is restored. .

  As described above, when there is not enough room in the household, if you are using a cooking device with multiple heating ports at the same time, the user himself can hurry to lower the heating power of the cooking device, etc. Power is automatically suppressed from the heating port that uses a large amount of power, so that the user's convenience is not lost by avoiding stopping heating as much as possible, and there is room for power in the home. Even if there is little, cooking can be continued smoothly. In addition, since power is reduced from the larger heating port, a certain amount of power reduction can be expected, and the breaker can be prevented from being interrupted. It is not necessary to be conscious of it, it is complicated because the device only needs to adjust the output power according to the received power adjustment request contents without sending complicated control processing by simply transmitting the power adjustment request signal to the device. Since a simple information processing function is not required, a system can be constructed at low cost. In addition, when there is enough power in the home after the heating cooker has been adjusted for power, a power reduction cancellation signal is received from the power control device, and the amount of power used is adjusted from the heating cooking means with the larger power reduction By determining, usability can be improved.

  In addition, when the power of the IH cooking heater is reduced or reduced, the power value corresponding to the heating mode shown in the table of FIG. 5 is compared with the usable power and the reduced power sent from the power control device, so that the heating mode is one level. Control is performed with the power difference value when changed. For example, in the table of FIG. 5, if left IH = L5, 900 W, and if reduction by 100 W is necessary, if left IH = L4, 200 W may be reduced more than necessary. In other words, if the output power is set to 800W and it is clearly shown that the display unit is operating at 800W, it is only necessary to reduce the necessary minimum power. Can be used.

  In addition, if the power control device sets a predetermined value for requesting reduced power to the device as the rated value for breaker cutoff, even if the current value detected by the power control device exceeds the predetermined value, the device with low priority By suppressing the power, it is possible to prevent the breaker from being interrupted, and to effectively operate the rated current capacity to operate the equipment. In addition, the power controller side does not need to be aware of the setting state such as the operation mode on the device side or the power consumption state, and simply sends the necessary reduced power to the device. Even if it is not necessary, the power can be suppressed in accordance with the received power reduction request, so that a complicated information processing function is not required, so that a system can be constructed at low cost.

  In addition, if the power supply system to be measured has a margin below the rated current, the communication power is streamlined by transmitting usable power notification signals in the order of priority from the devices in the power suppression state. In order to alleviate the power suppression state of the device or cancel the power suppression, the device is operated by effectively utilizing the rated current capacity.

  In addition, in the power reduction suppression control process, if the power can be increased even a little, the user is notified and the operation of increasing the power is performed by an operation after confirming the user. If the state of the cooking pan on the heating port can be accurately grasped by an image sensor or the like and the heating power (electric power) is returned, there is no concern about spilling, and the heating power (electric power) may be automatically restored.

  In this embodiment, when it is necessary to reduce the power while using a plurality of heating ports at the same time, the power is reduced from the heating port with the larger power consumption. If the user can select the power reduction method in consideration of the case where the power is reduced from the smaller heating port, the user has more options and the convenience is improved.

  In this embodiment, data is transmitted and received by specific low-power wireless communication that does not require wiring as a communication network unit. However, power line communication or wired connection may be used.

  In this embodiment, the IH cooking heater is used. However, any device may be used as long as it can set and operate a plurality of operations simultaneously in the same device.

  In addition, all of this embodiment can be configured in the same manner as a program for causing a computer to function as all or part of the means of the power control system.

  Note that the means and units described in this embodiment cooperate with hardware resources such as a CPU (or microcomputer), a RAM, a ROM, a storage / recording device, an electrical / information device including an I / O, a computer, a server, and the like. You may implement in the form of the program to work. In the form of a program, new functions can be easily distributed / updated and installed by recording them on a recording medium such as magnetic media or optical media or distributing them via a communication line such as the Internet.

  As described above, the heating cooker, the heating cooker control method, and the program according to the present invention use the IH cooking heater as the heating cooker. The same method can be applied as long as the device can be used.
